FIELD OF THE INVENTION
[0001] The present invention relates to a pouch and a manufacturing method thereof, and
more particularly to a pouch and a manufacturing method thereof, in which contents
can be conveniently heated or cooled.
BACKGROUND ART
[0002] In general, a pouch includes an accommodating section which accommodates a temperature
controllable object, a temperature control agent which is packaged in a container
separated from the accommodating section and heats or cools the temperature controllable
object accommodated in the accommodating section, and a liquid reactant bag filled
with a liquid reactant for exothermically or endothermically reacting with the temperature
control agent.
[0003] If a user breaks the liquid reactant bag, the exothermic or endothermic reaction
occurs to thereby heat or cool contents.
[0004] In a conventional pouch that includes the liquid reactant bag filed with the liquid
reactant for reacting with the temperature control agent, the liquid reactant bag
is so easily broken that unexpected exothermic or endothermic reaction may occur.
[0005] Meanwhile, if a heating space accommodating a heating element is opened, water or
the like liquid reactant may be added while contents are put into the poutch and then
sterilized.

MODES FOR CARRYING THE INVENTION
[0044] Hereinafter, a pouch according to exemplary embodiments of the present invention
will be described in detail with reference to accompanying drawings.
<First exemplary embodiment>
[0045] As shown in FIGs. 1 to 3, a pouch 200 according to a first exemplary embodiment includes
a contents-accommodating section 210 having a contents-accommodating space S1 for
accommodating contents; a temperature controller 220 placed in at least one side between
a front side and a rear side with respect to the contents-accommodating section 210
in order to heat or cool the contents-accommodating section 210; and a sealing portion
230 sealing up a liquid reactant entrance 222 communicating with temperature control
spaces S2, S3 inside the temperature controller 220.
[0046] Here, the contents may include food such as boiled rice, Bibimbap, soup, stew or
dry milk; a pad containing medicine for taking a hot massage or a cold massage, or
a mask pad containing beauty ingredients. Besides, the contents may be varied as long
as it has to be instantly heated or cooled.
[0047] The contents-accommodating section 210 includes a first front film 211 and a first
back film 213 placed in front and back to form the contents-accommodating space S1.
[0048] The first front film 211 and the first back film 213 may be made of a plastic film.
In more detail, the plastic film may include polyethylene (PE), polypropylene (PP),
or a polyethyelene terephthalate (PET). Besides, the first front film 211 and the
first back film 213 may be made of well-known synthetic resin films of various materials.
[0049] The temperature controller 220 couples with the contents-accommodating section 210,
in more detail, couples with the contents-accommodating section 210 so as to form
the temperature control spaces S2, S3 provided in at least one side between the front
and rear sides with respect to the contents-accommodating space S1.
[0050] FIGs. 1 to 3 illustrate that the temperature control spaces S2, S3 are formed in
front and back, but not limited thereto. As necessary, the temperature control spaces
S2, S3 may be formed at only one side.
[0051] The temperature controller 220 includes a second front film 221 coupled in the front
of the contents-accommodating section 210 and forming the temperature control space
52 in a front side; and a second back film 224 coupled in the back of the contents-accommodating
section 210 and forming the temperature control space 53 in a back side.
[0052] The second front film 221 and the second back film 224 made of a plastic film such
as polyethylene (PE), polypropylene (PP), or a polyethyelene terephthalate (PET).
Besides, the second front film 221 and the second back film 224 may be made of well-known
synthetic resin films of various materials.
[0053] Here, the temperature control spaces S2, S3 are isolated from the contents-accommodating
space
[0054] The front and back temperature control spaces S2, S3 can communicate with each other
through a communication space S4. The communication space S4 may be formed by arranging
the contents-accommodating section 210 so that the lower end portion 211c of the contents-accommodating
section 210 can be spaced apart from the lower end portion C1 of the temperature controller
220. In this case, the lower end portion C1 of the temperature controller 220 is a
part where the respective lower end portions of the second front film 221 and the
second back film 224 are coupled by ultrasonic waves or thermal welding. Of course,
coupling between the plastic films may be achieved various well-known methods besides
the foregoing ultrasonic waves or thermal welding.
[0055] Meanwhile, the contents-accommodating section 210 and the temperature controller
220 may be coupled with each other at left and right end portions C1, C2 by ultrasonic
waves or thermal welding.
[0056] The temperature controller 220 includes a plurality of temperature control agents
223, 225 respectively arranged in the plurality of temperature control spaces S2,
S3.
[0057] As described above, if the temperature control spaces S2, S3 are formed at only one
side between front and back sides, the temperature control agents 223, 225 may be
arranged at only one corresponding side.
[0058] Here, the temperature control agents 223, 225 includes heating elements 223a, 225a
to exothermically react with the liquid reactant, and absorption fabrics 223b, 225b
surrounding the heating elements 223a, 225a and absorbing the liquid reactant to make
the exothermic reaction smoothly.
[0059] As necessary, the absorption fabrics 223b, 225b may be omitted.
[0060] Also, a heat absorption agent endothermically reacting with the liquid reactant may
be used instead of the heating elements 223a, 225a. The heating element and the heat
absorption agent react with the liquid reactant to heat and cool the contents accommodated
in the contents-accommodating space S1.
[0061] The heating element may include at least one among calcium oxide, calcium hydroxide,
magnesium chloride, iron, and aluminum. Of course, the foregoing substances may be
replaced or changed by other substances as long as it can react with the liquid reactant.
[0062] The heat absorption agent may include at least one of ammonium nitrate (NH4NO3),
sodium acetate and urea.
[0063] Here, the plurality of temperature control agents 223, 225 may all include only the
heating elements, or only the heat absorption agent.
[0064] As necessary, in the plurality of temperature control agents 223, 225, the front
temperature control agent 223 may include only the heating element, and the back temperature
control agent 225 may include only the heat absorption agent. In this case, the front
and back temperature control spaces S2, S3 may not communicate with each other but
isolated from each other with the contents-accommodating space S1 therebetween.
[0065] The temperature controller 220 may further include a liquid reactant entrance 222
through which the liquid reactant is put into the temperature control spaces S2, S3.
[0066] The liquid reactant entrance 222 is to put the liquid reactant capable of reacting
with the temperature control agents 223, 225.
[0067] The liquid reactant entrance 222 is sealed up but openable in the sealing portion
230 to be described later.
[0068] Also, the liquid reactant entrance 222 is arranged at a lower side of the contents-accommodating
section 210 rather than an upper end thereof. That is, an upper edge of the liquid
reactant entrance 222 is lower than the upper end of the contents-accommodating section
210 so that a user can easily check the position of the liquid reactant entrance 222
with his/here naked eyes.
[0069] The liquid reactant entrance 222 may be formed as a partial upper end section G of
the second front film 221 of the temperature controller 220 is not coupled with the
first front film 211. At this time, the second front film 221 of the remaining upper
end section C3 may be permanently sealted up with the first front film 211.
[0070] Here, the drawings illustrate the liquid reactant entrance 222 is formed in the partial
upper end section G of the second front film 221. As necessary, the liquid reactant
entrance 222 may be formed in the entire upper end section of the second front film
221.
[0071] Also, the height of the liquid reactant entrance 222 from the lower end of the pouch
may be relatively greater than that of the remaining section C3 of the second front
film 221 from the lower end of the pouch. Of course, the liquid reactant entrance
222 may have the same height as the remaining section C3 of the second front film
221.
[0072] The liquid reactant entrance 222 may include a grip portion extended frontward to
be griped by a user's hand. Thus, a user can easily open the liquid reactant entrance
222.
[0073] Here, the grip portion 222a may be as shown in FIG. 3 formed to be folded down from
the first front film 211.
[0074] As necessary, instead of the grip portion 222a of FIG. 3, the upper end of the second
front film 221 may be as shown in FIG. 4 provided as it is spaced from the contents-accommodating
section 210, specifically from the first front film 211 by a predetermined space K.
Thus, a user puts his/her fingers in the space K and broadens the liquid reactant
entrance 222, thereby opening the liquid reactant entrance 222.
[0075] Meanwhile, the sealing portion 230 seals up the liquid reactant entrance 222. Thus,
it is possible to prevent foreign materials from entering the liquid reactant entrance
222 while the contents is put into and sterilized in the contents-accommodating section
S1 of the pouch 200. Such sterilization is essential when a retort pouch is produced
by putting stew, soup, boiled rice and the like instant foods into the pouch 200.
[0076] Accordingly, the pouch 200 according to an exemplary embodiment facilitates the manufacture
of the retort pouch.
[0077] As shown in FIG. 3, the sealing portion 230 may be provided between the second front
film 221 and the first front film 211 at a side lower than the grip portion 222a of
the liquid reactant entrance 222.
[0078] The sealing portion 230 may be provided to allow opening between the first front
film 211 and the second front film 221 when force of not less than a predetermined
magnitude is applied thereto. In other words, if external force of not less than a
predetermined magnitude is applied, the sealing portion 230 may open the liquid reactant
entrance 222. Thus, if a user grips and then pulls the grip portion 222a by force
of not less than a predetermined magnitude, the liquid reactant entrance 222 is opened.
[0079] A user puts the liquid reactant (for example, water) into the opened liquid reactant
entrance 222, thereby heating or cooling the contents accommodated in the contents-accommodating
space S1.
[0080] In particular, it is convenient for a user because the liquid reactant entrance 222
is easily opened to put the liquid reactant therein.
[0081] The sealing portion 230 may include an adhesive or a double-sided tape. As necessary,
the sealing portion 230 may be formed by fusing the first front film 211 and the second
front film 221 through thermal welding or ultrasonic waves. At this time, the first
front film 211 and the second front film 221 may be fused to such an extent as to
be separated from each other when the sealing portion 230 receives external force
of a predetermined magnitude.
[0082] Of course, the sealing portion 230 may be varied as long as it can seal up the liquid
reactant entrance and prevent foreign materials, such as liquid (e.g., water), from
being introduced therein if there is no external force of not less than a predetermined
magnitude.
[0083] Meanwhile, the pouch 200 may further include a ziplock 260 to selectively seal up
the upper portion of the contents-accommodating section 210.
[0084] The ziplock 260 includes a female zipper 261 formed inside the first front film 211
and a male zipper 263 formed inside of the first back film 213. Of course, the positions
of the female zipper 261 and the male zipper 263 may be exchanged.
[0085] Also, various well-known sealing means may be employed instead of the ziplock 260
as long as it can selectively seal up the contents-accommodating section 210.
[0086] Meanwhile, the pouch 200 may further include a transparent window 215, 216, 217 for
checking whether the contents-accommodating space S1 is sealed up or not. That is,
the defect of the contents-accommodating section 210 can be determined by naked eyes
through the transparent windows 215, 216, 217.
[0087] As shown in FIG. 1, the transparent window 215 may be arranged between the liquid
reactant entrance 222 and the upper end of the first front film 211. Through the transparent
window 215, contact between the first front film 211 and the contents accommodated
therein is checked by naked eyes, and it is thus possible to determine whether a product
is defective or not. For example, if solid food is put into the contents-accommodating
section 210 and then the contents-accommodating space S1 is vacuumized, it is possible
to determine by naked eyes through the transparent window 215 whether there is a trouble
in the vaccumization.
[0088] Meanwhile, the transparent window 216 may be as shown in FIGs. 1 and 2 formed in
a lower portion of the pouch 200. If the contents accommodated in the contents-accommodating
section 210 is liquid and the liquid leaks out because the contents-accommodating
section 210 is defective, it is possible to determine by naked eyes through the transparent
window 216 of the lower portion whether the product is defective or not. To make it
easier to determine through the transparent window 216 of the lower portion whether
the contents-accommodating section 210 is sealed up or not, a corresponding region
of the second front film 221 formed with the transparent window 216 may be transparently
formed, but a corresponding region of the first front film 221 may be opaque. For
example, the second front film 221 may be entirely made of a transparent film, while
the first front film 221 may be entirely made of an opaque film.
[0089] Also, the transparent window 217 formed in a vertical direction may be as shown in
FIG. 1 formed at one side between left and right sides of the pouch 200 along a lengthwise
direction. Thus, a user leans the pouch 200 and checks by his/her naked eyes through
the transparent window 217 whether the contents accommodated in the contents-accommodating
section 210 leak out or not, thereby determining whether a product is defective or
not.
[0090] The plurality of transparent windows 215, 216, 217 are to check whether the contents-accommodating
space S1 of the contents-accommodating section 210 is surely isolated from the temperature
control spaces S2, S3. If it is chedcked through the plurality of transparent windows
215, 216, 217 that there is no defect in a product, the contents of the contents-accommodating
space S1 is not affected by a byproduct produced by the exothermic or endothermic
reaction within the temperature control spaces S2, S3.
[0091] The drawings show the plurality of transparent windows 215, 216, 217, but the number
and positions of the transparent windows 215, 216, 217 may be varied.
[0092] Meanwhile, the foregoing description illustrates that the liquid reactant entrance
222 is formed at only one side between the front and back sides, but not limited thereto.
Alternatively, the liquid reactant entrance 222 may be formed at both the front and
back sides.
<Second exemplary embodiment>
[0093] Meanwhile, a pouch 200a according to the second exemplary embodiment may as shown
in FIG. 5 include a contents-accommodating section 210a, a temperature controller
220 and a sealing portion 230.
[0094] The contents-accommodating section 210a of the pouch 200 according to the first exemplary
embodiment has the lower end 211c spaced apart from the lower end of the temperature
controller 220 as shown in FIG. 3. On the other hand, in the pouch 200a according
to the second exemplary embodiment, as shown in FIG. 5, the lower end of the contents-accommodating
section 210a is extended to the lower end of the temperature controller 220 so that
the contents-accommodating section 210a and the temperature controller 220 can be
coupled with each other in a lower region by ultrasonic waves or thermal welding.
[0095] A communication hole 211b, 213b may be formed in the contents-accommodating section
210a so that the front and back temperature control spaces S2, S3 can communicate
with each other. Here, the edge of the communication hole 211b, 213b is sealed up
to prevent the contents accommodated in the contents-accommodating space S1 from leaking
out through the communication hole 211b, 213b.
<Third exemplary embodiment>
[0096] A pouch 200b according to the third exemplary embodiment may as shown in FIGs. 6
and 7 include a contents-accommodating section 210, a temperature controller 220 and
a sealing portion 240.
[0097] According to the third exemplary embodiment, the contents-accommodating section 210
and the temperature controller 220 except the sealing portion 240 are the same as
those of the first exemplary embodiment.
[0098] According to the third exemplary embodiment, the sealing portion 240 may include
an adhesive tape 240 to seal up the upper end of the liquid reactant entrance 222.
Thus, it is possible to prevent foreign materials (in particular, liquid) from being
introduced into the temperature control spaces S2, S3 while the contents are put into
the contents-accommodating section S1 and sterilized after the upper end of the contents-accommodating
section S1 is sealed up.
[0099] Meanwhile, the adhesive tape 240 includes an extended portion 241 extended so that
one side there of can be gripped. Thus, a user can easily put the liquid reactant
into the pouch 200b by pulling the extended portion 241 and removing the adhesive
tape 240.
<Fourth exemplary embodiment>
[0100] A pouch 200c according to a fourth exemplary embodiment includes a contents-accommodating
section 210; a temperature controller 220; a sealing portion 230 and a pouch stand
250 as shown in FIG. 8.
[0101] The pouch 200c according to the fourth exemplary embodiment allows the contents-accommodating
section 210 to stand by itself without any separate standing device as compared with
the pouches 200, 200a, 200b according to the first to third exemplary embodiments.
[0102] The pouch stand 250 is coupled to a lower side of the pouch 200c so that the pouch
200c can stand.
[0103] In more detail, one end of the pouch stand 250 is coupled to the lower end portion
of the second front film 221a, thereby forming a front lower edge. Also, the other
end of the pouch stand 250 is coupled to the lower end of the second back film 224a,
thereby forming a back lower edge spaced apart from the front lower edge. Thus, the
lower edges of the pouch 200c are broadened so that the pouch 200c can stand by itself
without any separate device.
[0104] Here, if it is desired to change the pouch 200a as shown in FIG. 4 in a standable
form, the pouch stand 250 may be interposed between the lower end of the first front
film 211a and the lower end of the first back film 213a.
[0105] Meanwhile, the pouch stand 250 may include a transparent window 253 through which
the inside of the pouch 200c can be seen. In the case of the standable pouch 200c
according to the fourth exemplary embodiment, a bottom formed by the pouch stand 250
may have a transparent window 253 besides the plurality of transparent windows 215,
216, 217 described in the first exemplary embodiment. The transparent window 253 may
be formed by making at least one region of the pouch stand 250 with a transparent
substance. As necessary, the pouch stand 250 may be entirely made of a transparent
substance. Thus, a user can determine whether a product is defective or not with his/her
naked eyes through the transparent window 253 formed on the bottom of the pouch 200c.
[0106] When the contents-accommodating section 210 is filled with the contents, the lower
portion of the contents-accommodating section 210 may be expanded toward the pouch
stand 25. In more detail, the lower portion of the contents-accommodating section
210 is creased so that the contents-accommodating section 210 can expand toward the
pouch stand 25 when the contents-accommodating section 210 is filled with the contents.
[0107] Also, the lower portion of the contents-accommodating section 210 is arranged near
to the inside of the pouch stand 25 so that both the pouch stand 25 and the contents-accommodating
section 210 can expand toward the bottom supporting the pouch 200 by the weight of
the contents accommodated in the contents-accommodating section 210.
<Fifth exemplary embodiment>
[0108] A pouch 200d according to a fifh exemplary embodiment as shown in FIG. 9 includes
a contents-accommodating section 210b; a temperature controller 220; a sealing portion
230 and a pouch stand 250.
[0109] According to the fifth exemplary embodiment, the contents-accommodating section 210b
may be formed by sealing up a first front film 211b, an inner bottom film 218 and
a first back film 213b. In more detail, one end and the other end of the inner bottom
film 218 are respectively sealed and coupled to the lower end of the first front film
211b and the lower end of the first back film 213b, thereby forming the contents-accommodating
section 210b. The inner bottom film 218 surely secures a lower space of the contents-accommodating
section 210b so that the contents-accommodating space S1 can be filled with more contents.
<Sixth exemplary embodiment>
[0110] FIG. 10 is a perspective view of a pouch according to the sixth exemplary embodiment,
FIG. 11 is a section view, taken along line A2-A2 of FIG. 10, FIG. 12 is a section
view showing that the pouch shown in FIG. 11 is filled with the temperature controllable
object, and FIG. 13 is a section view showing that a sealing portion is opened to
put a liquid reactant into the temperature control space of the pouch shown in FIG.
11.
[0111] As shown in FIGs. 10 to 13, a pouch 100 according to the sixth exemplary embodiment
includes an accommodating section 110, a temperature controller 130 provided with
a temperature control agent 131, a sealing portion 140, a grip portion 150, a supporter
160, a sealing-bar attachment-preventing portion 170 and a cutting portion 180. The
pouch 100 according to the sixth exemplary embodiment does not include the temperature
control agent 131 and the liquid reactant W for the exothermic or endothermic reaction.
That is, the liquid reactant W is put into the poutch 100 from the outside in order
to control the temperature of the temperature controllable object 10.
[0112] Here, the temperature controllable object 10 includes various instant food such as
the retort pouch. For example, the contents may include food such as boiled rice,
Bibimbap, soup, stew or dry milk; a pad containing medicine for taking a hot massage
or a cold massage, or a mask pad containing beauty ingredients. Besides, the contents
may be varied as long as it has to be instantly heated or cooled.
[0113] The accommodating section 110 includes a first accommodating section film 112 and
a second accommodating section film 114. An accommodating space 116 for accommodating
the temperature controllable object 10 is formed between the first accommodating section
film 112 and the second accommodating section film 114. Here, the first accommodating
section film 112 and the second accommodating section film 114 may be made of a heat-resistant
plastic film.
[0114] In more detail, the accommodating section 110 may be made of the plastic film such
as polyethylene (PE), polypropylene (PP), or a polyethyelene terephthalate (PET).
Of course, the first accommodating section film 112 and the second accommodating section
film 114 constituting the accommodating section 110 may be made of well-know synthetic
resin films of various materials.
[0115] For example, the first accommodating section film 112 may include a CPP film having
a thickness of 60
µm, an aluminum film having a thickness of 9
µm, or a combination film between a nylon film having a thickness of 15
µm and a CPP film having a thickness of 60
µm. Of course, this is nothing but illustrative. The first accommodating section film
112 may include a combination film of various materials, or as necessary include a
film of a single material. The second accommodating section film 114 may be made of
the same material as that of the first accommodating section film 112.
[0116] The first accommodating section film 112 and the second accommodating section film
114 form an envelope shape as the other side and both sides connecting one side and
the other side are adhered and sealed so as to open one side. As the first accommodating
section film 112 and the second accommodating section film 114 are adhered, the accommodating
space 116 accommodating the temperature controllable object 10 is formed. Trough an
opening side of the accommodating section 110, the temperature controllable object
10 is filled in the accommodating space 116, and the opening side is sealed up by
the sealing-bar attachment-preventing portion 170 to be described later after the
temperature controllable object 10 is completely filled.
[0117] The temperature controller 130 may be formed at one side between both sides of the
accommodating section 110. The temperature control agent 131 is accommodated in between
the temperature controller 130 and the outer side of the accommodating section 110,
and exothermally or endothermally reacts with the liquid reactant w to be inserted,
thereby heating or cooling the temperature controllable object 10.
[0118] The temperature controller 130 according to the sixth exemplary embodiment includes
the temperature control agent 131 arranged at least one side between front and back
sides of the accommodating section 110 and heating or cooling the temperature controllable
object (i.e., the contents); and a temperature control space forming member 132 provided
in a lower side of the accommodating section 110 rather than an upper side thereof,
having the liquid reactant entrance 136 through which the liquid reactant w is inserted,
and forming a temperature control space 134 where the exothermic or endothermic reaction
occurs.
[0119] The temperature control agent 131 includes a reactant 131b and a reactant accommodating
section 131a. According to the sixth exemplary embodiment, the temperature control
agent 131 is arranged at one side between both sides of the accommodating section
110. The temperature control agent 131 may be arranged at a side facing the first
accommodating section film 112. The temperature control agent 131 reacts with the
liquid reactant w such as water inserted from the outside.
[0120] The reactant 131b includes the heating element or the heat absorption agent in accordance
with whether to heat or cool the temperature controllable object 10 accommodated in
the accommodating section 110. The reactant 131b may include at least one as the heating
element among calcium oxide (CaO), calcium hydroxide (Ca(OH)2), magnesium chloride
(MgCl2), iron (Fe) and aluminum (Al). Here, the reactant 131b may be replaced or changed
by other substances as long as it can exothermally react with the liquid reactant
w.
[0121] On the other hand, the reactant 131b may include at least one as the heat absorption
agent among ammonium nitrate (NH4NO3), sodium acetate (CH3COONa) and (urea). Of course,
the reactant 131b may be replaced or changed by other substances as long as it can
endothermally react with the liquid reactant w.
[0122] The reactant accommodating section 131a accommodates the reactant 131b. The reactant
accommodating section 131a includes a body 131a1 and a partition 131a2. The reactant
accommodating section 131a is provided as an absorption fabric to quickly absorb the
liquid reactant w. As necessary, the reactant accommodating section 131a may be made
of not the absorption fabric but other substances.
[0123] The body 131a1 is provided to accommodate the reactant 131b. Here, the body 131a1
according to an exemplary embodiment is partitioned into four accommodating regions
by the partition 131a2. Thus, the reactant 131b is accommodated in each of the plurality
of accommodating regions partitioned by the partition 131a2, thereby preventing the
reactant 131b from being leaning by its own weight. Also, the reactant 131b is accommodated
in each of the plurality of accommodating regions, and thus the divided reactant 131b
individually contacts the liquid reactant w, thereby making a temperature control
reaction quickly.
[0124] The temperature control space forming member 132 together with the first accommodating
section film 112 forms the temperature control space 134 to accommodate the temperature
control agent 131. The temperature control space 134 is a space where the exothermic
or endothermic reaction occurs when the liquid reactant w is inserted, and has a margin
space to accommodate the liquid reactant w in addition to the temperature control
agent 131.
[0125] Here, the temperature control space forming member 132 may be made of a transparent
synthetic resin film so that the liquid reactant w and the temperature control agent
131 to be inserted can be checked by naked eyes. Of course, the temperature control
space forming member 132 may be partially made of the transparent synthetic resin
film checkable by naked eyes. Of course, checkability by naked eyes is optional, and
thus an opaque film may be used as necessary. The temperature controller 130 may be
provided smaller than the accommodating section 110 so that an upper opening of the
accommodating section 110 for inserting the temperature controllable object 10 can
be exposed. According to an exemplary embodiment, the height of the temperature control
space forming member 132 may be eight tenth with respect to the height of the accommodating
section 110.
[0126] The temperature control space forming member 132 may have an upper end lower than
that of the contents-accommodating section 110.
[0127] The temperature control space forming member 132 may be made of the plastic film.
For example, the temperature control space forming member 132 may be the plastic film
where a PET film having a thickness of 12
µm and a CPP film having a thickness of 60
µm are combined. Of course, this is nothing but illustrative. Alternatively, the plastic
film may be a combination film where films of various well-known substances are combined
or a single material film.
[0128] Meanwhile, the temperature controller 130 adjacent to the opening of the accommodating
section 110 includes a liquid reactant insertion portion 136 for opening and closing
the temperature control space 134 to insert the liquid reactant therethrough. The
liquid reactant insertion portion 136 is coupled to the contents-accommodating section
110 by the sealing portion 140 to be described later, and seals up the temperature
control space 134.
[0129] The liquid reactant insertion portion 136 may be spaced part from the sealing portion
140 or the first accommodating section film 112 when force of not less than a predetermined
magnitude is applied for inserting the liquid reactant w in the temperature control
space 134. Thus, the upside of the temperature control space 134 is opened so that
the liquid reactant w can be inserted in the temperature control space 134.
[0130] The sealing portion 140 seals up the accommodating section 110 and the temperature
controller 130, specifically, the liquid reactant insertion portion 136, thereby sealing
up the temperature control space 134. Here, the sealing portion 140 seals up the accommodating
section 110 and the liquid reactant insertion portion 136 with predetermined intensity
of adhesion so that the temperature control space 134 can be opened when force of
not less than a predetermined magnitude is applied for spacing the liquid reactant
insertion portion 136 apart from the accommodating section 110. That is, when the
liquid reactant insertion portion 136 is pulled by force of not less than a predetermined
magnitude strong enough to overcome the adhesion, the temperature control space 134
is opened. On the other hand, if force of not less than a predetermined magnitude
is not applied, the sealing is maintained so that foreign materials including the
liquid reactant cannot be introduced into the temperature control space 134.
[0131] Here, the sealing portion 140 may have an adhesive strength of not less than 200gf/cm
2 and not more than 5kgf/ cm
2. In experimental results, if the adhesive strength is less than 200gf/cm
2, the sealing may not be maintained when the temperature controllable object 10 is
filled and then heated to expand the temperature control space 134. On the other hand,
the adhesive strength is more than 5kgf/cm
2, it is difficult for a regular adult to open the temperature control space 134.
[0132] Preferably, the sealing portion 140 may have a adhesive strength of 500gf/cm
2 ∼ 3kgf/cm
2.
[0133] According to an exemplary embodiment, the sealing portion 140 is placed on the planar
surface of the first accommodating section film 112, and seals up between the liquid
reactant insertion portion 136 of the temperature controlled 130and the first accommodating
section film 112. Thus, the sealing portion 140 seals up between the first accommodating
section film 112 and the liquid reactant insertion portion 136, and prevents foreign
materials from being introduced into the temperature control space 134 while the temperature
controllable object 10 is filled in the accommodating space 116 of the accommodating
section 110 and then sterilized. Such sterilization is essential when a retort pouch
is produced by putting stew, soup, boiled rice and the like instant foods into the
pouch 100.
[0134] Meanwhile, the sealing portion 140 may be released from the sealing with the liquid
reactant insertion portion 136 when force of not less than a certain magnitude is
applied for inserting the liquid reactant w into the temperature control space 134
as temperature control is required for the temperature controllable object 10. Then,
the liquid reactant insertion portion 136 is opened to open the temperature control
space 134, so that the liquid reactant w can be inserted in the temperature control
space 134. Accordingly, the exothermic or endothermic reaction occurs between the
temperature control agent 131 and the liquid reactant w.
[0135] Here, the sealing portion 140 may include at least one among liquid adhesive for
adhereing the first accommodating section film 112 and the liquid reactant insertion
portion 136, a solid adhesive tape, and an easy peel film provided between the first
accommodating section film 112 and the liquid reactant insertion portion 136.
[0136] Here, the solid adhesive tape may be a film type tape, one or both sides of which
the adhesive is applied to.
[0137] The easy peel film couples both films thereof with predetermine thermal adhesion
when heat of a predetermined temperature range is applied. Here, the coupling force
or adhesion may be controlled by adjusting the temperature range of heat applied to
the easy peel film.
[0138] Here, the adhesive strength due to the sealing portion 140 between the liquid reactant
entrance 136 and the accommodating section 110 is weaker than contact strength between
the temperature control space forming member 132 and the accommodating section 110
besides the liquid reactant entrance 136.
[0139] In more detail, the liquid reactant entrance 136 is expected to be opened so as to
insert the liquid reactant in the temperature control space 134, and therefore the
adhesive strength of the partial sealing portion C6 between the liquid reactant entrance
136 and the accommodating section 110 may be weaker than the adhesive strength of
the partial sealing portion C7 in a lateral edge between the temperature control space
forming member 132 and the accommodating section 110. This may be achieved by changing
the temperature range of the sealing bar used when sealing the partial sealing portions
C7, C6. Such temperature range will be described later.
[0140] Meanwhile, the grip portion 150 is provided to grip the liquid reactant insertion
portion 136 of the temperature controller 130. The grip portion 150 is extended from
the liquid reactant insertion portion 136 and formed integrally with the liquid reactant
insertion portion 136.
[0141] The grip portion 150 may protrude from the liquid reactant insertion portion 136.
The grip portion 150 may be provided in a center region of the liquid reactant insertion
portion 136. The grip portion 150 protrudes from the center region of the liquid reactant
insertion portion 136 and is gripped by a user. In particular, the grip portion 150
is gripped by a user and transfers a user's force to the liquid reactant insertion
portion 136 so that the liquid reactant insertion portion 136 can be released from
the accommodating section 110. To make a user easily grip the grip portion 150 and
efficiently transfer his/her force, the grip portion 150 may protrude from the center
portion of the liquid reactant insertion portion 136.
[0142] Of course, the grip portion 150 may be provided at both sides of the liquid reactant
insertion portion 136.
[0143] The supporter 160 is provided in at least one of the outer side of the accommodating
section 110 forming the temperature control space 134 and the inner side of the temperature
controller 130. The supporter 160 supports the temperature control agent 131 in the
temperature control space 134 and prevents the temperature control agent 131 from
moving. That is, the supporter 160 prevents the temperature control agent 131 from
moving during a distribution process of the pouch 100. The supporter 160 is not essential
for the pouch 100, and may be omitted as necessary.
[0144] According to an exemplary embodiment, the supporter 160 is placed on an inner side
of the temperature control space forming member 132 and supports the temperature control
agent 131. Of course, the supporter 160 may be placed on an outer side of the first
accommodating section film 112 and support the temperature control agent 131. The
supporter 160 may be made of various adhesive materials such as the adhesive tape
in order to support the temperature control agent 131 against the temperature control
space forming member 132.
[0145] Meanwhile, when the sealing-bar attachment-preventing portion 170 seals up the upper
ends of the first accommodating pack film 112 and the second accommodating pack film
114 by the sealing bar 131a2 having a predetermined sealing temperature in order to
seal up the upper side of the accommodating section 110, the first accommodating pack
film 112 is attached to and not separated from the sealing bar.
[0146] In more detail, the first accommodating pack film 112 is as described above made
of a single CPP film or a combination film where the CPP film is exposed. The CPP
film may be attached to and not well separated from the sealing bar, and to prevent
this, the sealing-bar attachment-preventing portion 170 may be provided in the accommodating
section 110 contacting the sealing bar.
[0147] The PET substance may be used as a material not well attached to the sealing bar.
The sealing-bar attachment-preventing portion 170 may include a film of which a part
exposed frontward is combined with the PET film, or a single PET film.
[0148] For example, the sealing-bar attachment-preventing portion 170 may be the same plastic
film as the temperature control space forming member 132, where the PET film having
a thickness of 12
µm and the CPP film having a thickness of 60
µm are combined. Here, the PET film has to be arranged to be exposed frontward so that
the PET film can contact the sealing bar.
[0149] Here, it is just illustrative that the PET is used as a material for the sealing-bar
attachment-preventing portion 170. The PET may be replaced by the plastic films of
various well known materials as long as it cannot well attached to the sealing bar.
[0150] The cutting portion 180 is provided between the liquid reactant insertion portion
136 and the sealing-bar attachment-preventing portion 170.
[0151] The cutting portion 180 may include a notch cut in a transverse direction at one
or both sides of the accommodating section 110 so that the accommodating section 110
can be torn when transverse force of not less than a certain magnitude is applied.
[0152] The cutting portion may be so thin that the portion cut by the notch can be easily
torn.
[0153] As shown in FIG. 11, since the first accommodating section film 112 and the second
accommodating section film 114 exist in the cutting portion AA1 formed with the notch,
it is thinner than three layered films of the sealing-bar attachment-preventing member
170, and the first and second accommodating section films 112, 114 placed above the
accommodating section 110.
[0154] Also, total four layered films of the temperature control space forming member 132,
the sealing portion 140, the first accommodating section film 112 and the second accommodating
section film 114 exist below the cutting portion AA1, and therefore the cutting portion
AA1 having total two layered films is relatively thin. Thus, the cutting portion AA1
can be more easily torn.
[0155] Meanwhile, the supporter 160, the sealing-bar attachment-preventing portion 170 and
the cutting portion 180 described above are not essential, and all or a part of them
160, 170, 180 may be omitted as necessary.
[0156] Meanwhile, the foregoing illustrates that the lateral edges C7 of the first accommodating
section film 112 and the second accommodating section film 114 of the accommodating
section 110 are directly sealed up. As necessary, the cross section of the lateral
edges may be creased like

so that a user can more easily grip the lateral side of the pouch 100. This may be
achieved by interposing a separate fim between the lateral edges of the first accommodating
section film 112 and the second accommodating section film 114 and thus broadening
both edges.
<Seventh exemplary embodiment>
[0157] FIG. 14 is a section view of a pouch according to a seventh exemplary embodiment,
and FIG. 15 is a section view showing that a temperature controllable object is filled
in the pouch shown in FIG. 14
[0158] As shown in FIG. 14 and FIG. 15, a pouch 300 according to the seventh exemplary embodiment
includes a temperature controller 330 provided with a plurality of temperature control
agents 131 respectively arranged in the first accommodating section film 112 and the
second accommodating section film 114 of the accommodating section 110. Here, among
the elements of the pouch 300 according to the seventh exemplary embodiment, the accommodating
section 110, the temperature control agent 131, the supporter 160, the sealing-bar
attachment-preventing portion 170 and the cutting portion 180 are the same as those
of the sixth exemplary embodiment, and thus repetitive descriptions thereof will be
avoided.
[0159] The temperature controller 330 includes a first temperature control space forming
member 331, a second temperature control space forming member 332, a first liquid
reactant insertion portion 337 and a second liquid reactant insertion portion 338.
The first temperature control space forming member 331 and the second temperature
control space forming member 332 respectively accommodate the first accommodating
section film 112 and the second accommodating section film 114. Beween the first temperature
control space forming member 331 and the second temperature control space forming
member 332 and between the first accommodating section film 112 and the second accommodating
section film 114 are formed the first temperature control space 334 and the second
temperature control space 335, respectively. Here, each of the first temperature control
space 334 and the second temperature control space 335 accommodate the temperature
control agent 131.
[0160] Further, the upper regions of the first temperature control space forming member
331 and the second temperature control space forming member 332 are provided with
the first liquid reactant insertion portion 337 and the second liquid reactant insertion
portion 338 to open and close the temperature control spaces 334, 335, respectively.
[0161] The sealing portion 340 is provided to allow the first liquid reactant insertion
portion 337 and the second liquid reactant insertion portion 338 to seal up the first
temperature control space 334 and the second temperature control space 335, respectively.
The sealing portion 340 includes the first sealing portion 342 for sealing up between
the first accommodating section film 112 and the first liquid reactant insertion portion
337, and a second sealing portion 344 for sealing up between the second accommodating
section film 114 and the second liquid reactant insertion portion 338. Here, the first
sealing portion 342 and the second sealing portion 344 may include the liquid adhesive
or the solid adhesive tape or the easy peel film like the sealing portion 140 according
to the sixth exemplary embodiment.
[0162] The grip portion 350 includes a first grip portion 352 and a second grip portion
354 to be gripped so that the first liquid reactant insertion portion 337 and the
second liquid reactant insertion portion 338 can open the first temperature control
space 334 and the second temperature control space 335, respectively. The first grip
portion 352 may be placed in the center region of the first liquid reactant insertion
portion 337, and the second grip portion 354 may be placed in the center regionthe
second liquid reactant insertion portion 338. The first grip portion 352 and the second
grip portion 354 have the same shape as that of the grip portion 150 according to
the sixth exemplary embodiment. Of course, the first grip portion 352 and the second
grip portion 354 may have a different shape from the grip portion 150 according to
the sixth exemplary embodiment.
[0163] As described above, the pouch 300 according to the seventh exemplary embodiment accommodates
two temperature control agents 131 in two temperature control spaces 334, 335 on the
contrary to the sixth exemplary embodiment, and thus can more quickly control the
temperature of the temperature controllable object 10 than the pouch 100 according
to the sixth exemplary embodiment.
<Eighth exemplary embodiment>
[0164] FIG. 16 is a perspective view of a pouch according to an eighth exemplary embodiment.
[0165] A pouch 500 according to the eighth exemplary embodiment as shown in FIG. 16 includes
a grip portion 550 different from those of the pouches 100, 300 according to the first
and seventh exemplary embodiments.
[0166] The grip portion 550 according to the eighth exemplary embodiment includes a grip
body 552 and a cutting line 554. The grip body 552 is provided in a transvers direction
of the drawing at the upper opening of the temperature control space 134, that is,
a region to be sealed up by the sealing portion 140. The cutting line 554 is provided
to open the temperature control space 134 when force of not less than a certain magnitude
is applied to the grip body 552. That is, the cutting line 554 is removed from the
temperature controller 130 when transverse force is applied to the grip body 552,
and opens the temperature control space 134.
[0167] Here, in the pouch according to the eighth exemplary embodiment, foreign materials
may enter the temperature control space 134 through the cutting line 554 during a
sterilization process. Therefore, the pouch according to the eighth exemplary embodiment
can be used when there is no need of the sterilization process after the temperature
controllable object (i.e., the contents) is filled in the accommodating section 110
of the pouch 500. For example, if the temperature controllable object (i.e., the contents)
is solid dried food or a liquid or solid beauty product, the sterilization process
may be not needed.
[0168] Here, a partial region of the grip body 552 may protrude from the accommodating section
110 so that a user can easily grip it.
[0169] The grip portion 550 according to the eighth exemplary embodiment is provided with
the cutting line 554 at the opening side of the temperature controller 130, thereby
improving the sealing of the temperature control space 134 and convenience when opening
the temperature control space 134.
<Ninth exemplary embodiment>
[0170] Lastly, FIG. 17 is a section view of a pouch according to a ninth exemplary embodiment.
[0171] The pouch 700 according to the ninth exemplary embodiment may be applied to the pouches
100, 300, 500 according to the first to eighthexemplary embodiments. The pouch 700
according to the ninth exemplary embodiment includes a pouch stand 790 so as to make
the accommodating section 110 stand.
[0172] The pouch stand 790 according to an exemplary embodiment is provided between the
first accommodating section film 112 and the second accommodating section film 114
of second accommodating section 110. Here, the pouch stand 700 may be made of a film
thickner than the first accommodating section film 112 and the second accommodating
section film 114 constituting the accommodating section 110. Of course, the pouch
stand 790 may be placed between the accommodating section 110 and the temperature
controller 130, but may be placed between the first accommodating section film 112
and the second accommodating section film 114 constituting the accommodating section
110 according to an exemplary embodiment in order to stably keep a standing state
the pouch 700.
[0173] Thus, the pouch stand 790 is provided to make the pouch 700 stand, so that the temperature
control for the temperature controllable object inside the pouch 700 can be stably
performed.
<Tenth exemplary embodiment>
[0174] A pouch 100a according to a tenth exemplary embodiment as shown in FIG. 18 to FIG.
20 includes an accommodating section 110; a temperature controller 130 including a
temperature control agent 131, a liquid reactant entrance 136 and a temperature control
space forming member 132; a sealing portion 140, a cutting portion 180 and a pouch
stand 790.
[0175] The pouch 100a according to the tenth exemplary embodiment does not include the supporter
160 and the sealing-bar attachment-preventing portion 170 as compared with that 100
of the sixth exemplary embodiment.
[0176] As shown in FIG. 19, in the state that the upper end portions of the first and second
accommodating section films 112, 114 are not sealed up and the upper portion of the
accommodating section 110 is being opened, the temperature controllable object 10
is inserted in the accommodating section 110 along an inserting direction D.
[0177] To heat or cool the temperature controllable object 10 accommodated in the accommodating
section 110, a user first grips the grip portion 150 as shown in FIG. 21, and pulls
the liquid reactant entrance 136 in a direction F, thereby spacing it apart from the
accommodating section 110. At this time, if force of not less than a predetermined
magnitude is applied for spacing the liquid reactant entrance 136 apart from the accommodating
section 110, the liquid reactant entrance 136 is opened. As described above, the thermal
adhesive strength in the sealing region C6 due to the sealing portion 150 is weaker
than the thermal adhesive strength of the edge portionC7 of the accommodating section
110, and therefore the liquid reactant entrance 136 can be more easily opened than
other portions.
[0178] In the state that the temperature control space 134 is being opened, the liquid reactant
is inserted in a direction H. Accordingly, the exothermic or endothermic reaction
occurs between the liquid reactant and the temperature control agent 131 within the
temperature control space 134, and thus the temperature controllable object 10 accommodated
in the accommodating space 116 is heated or cooled.
[0179] After a lapse of predetermined time, a user uses the grip portion 180 to cut open
the upper end of the accommodating section 110. Thus, a user takes in, takes out or
uses the heated or coold temperature controllable object 10 through the accommodating
section 110 having the opened upper portion.
<Eleventh exemplary embodiment>
[0180] A pouch 300a according to an eleventh exemplary embodiment as shown in FIG. 22 includes
an accommodating section 110; a temperature controller 330 provided with a plurality
of temperature control agents 131 respectively arranged in a first accommodating section
film 112 and the second accommodating section film 114; and a sealing portion 140a
for sealing up a plurality of temperature control spaces 334, 335 accommodating a
plurality of temperature control agents 131.
[0181] As compared with the pouch 300 according to the seventh exemplary embodiment shown
in FIG. 14, the pouch 300a according to the eleventh exemplary embodiment does not
include the supporter (160 in FIG. 14) and the sealing-bar attachment-preventing portion(170
in FIG. 14) of the eventh exemplary embodiment. Also, the pouch 300a according to
the eleventh exemplary embodiment is different in including a pouch stand 790 and
standing from that 300 of the seventh exemplary embodiment.
[0182] The sealing portion 140 includes a first sealing portion 141 for sealing up the first
temperature control space 334 and a second sealing portion 143 for sealing up the
second temperature control space 335.
[0183] The first and second sealing portions 141, 143 may be made of the same substance
as that of the foregoing sealing portion 140.
[0184] The first and second sealing portions 141, 143 seal up between the first temperature
control space forming member 331 and the first accommodating section film 112 and
between the second temperature control space forming member 332 and the second accommodating
section film 114 so that the first and second liquid reactant entrances 337, 338 can
be opened when force of not less than a certain magnitude is applied for spacing the
first and second liquid reactant entrances 337, 338 and the contents-accommodating
section 110 apart from each other.
[0185] Here, a user employs the plurality of first grip portion 352 and second grip portion
354 as shown in FIG. 22 to respectively open the first and second temperature control
spaces 334, 335, and inserts the liquid reactant therein, thereby heating or cooling
the temperature controllable object within the accommodating space 116.
<Twelfth exemplary embodiment>
[0186] A pouch 300b according to a twelfth exemplary embodiment as shown in FIG. 23 includes
an accommodating section 110a including a first accommodating section film 112, a
second accommodating section film 114 and a spacing film 115 spaced apart from the
pouch stand 790; a temperature controller 230 including the plurality of temperature
control agents 131 respectively arranged in the first accommodating section film 112
and the second accommodating section film 114; a sealing portion 140 for sealing up
one among the plurality of temperature control spaces 234, 235 accommodating the plurality
of temperature control agents 131; a grip portion 150; and a cutting portion (180
in FIG. 1).
[0187] The pouch 300b according to the twelfth exemplary embodiment does not include the
supporter (600 in FIG. 14) as compared with the pouch 300 according to the seventh
exemplary embodiment shown in FIG. 14. Also, the pouch 300b according to the twelfth
exemplary embodiment is different from that 300 of the seventh exemplary embodiment
in that it includes the pouch stand 790 and is capable of standing, that the lower
portion of the accommodating section 110a is spaced apart from the pouch stand 790,
that the sealing portion 140 is arranged at one side among the plurality of temperature
control spaces 234, 235, that the sealing-bar attachment-preventing portion 170 is
arranged at one side between the front and back sides of the pouch 300b, and that
the plurality of temperature control spaces 234, 235 communicate with each other.
[0188] The first and second accommodating section films 112, 114 and the spacing film 115
of the accommodating section 110a may be provided as a single material film. As necessary,
they may be manufactured as individually separately cut-open films and then sealed
up.
[0189] The temperature controller 230 includes first and second temperature control space
forming members 231, 232 sealed with the first and second accommodating section films
112, 114 to form the first and second temperature control spaces 234, 234; and the
plurality of temperature control agents 131 respectively accommodated in the first
and second temperature control spaces 231, 232.
[0190] The upper end of the first temperature control space forming member 231 is lower
than the upper end of the contents-accommodating section 110.
[0191] The first temperature control space forming member 231 includes a liquid reactant
entrance 237 through which the liquid reactant for exothermically or endothermically
reacting with the temperature control agent 131 can be inserted in the first temperature
control space 231.
[0192] The sealing portion 140 is provided between the liquid reactant entrance 237 of the
first temperature control space forming member 231 and the first accommodating section
film 112.
[0193] The liquid reactant entrance 237, the sealing portion 140 and the first accommodating
section film 112 are thermally adhered by heat and thus sealed up.
[0194] After the temperature controllable object (i.e., the contents) is filled in the state
that the accommodating section 110a is being opened, the sealing bar heated up to
a predetermined temperature applies heat along the upper end edges of the accommodating
section 110 toward the sealing-bar attachment-preventing portion 170, thereby sealing
up the upper end of the accommodating section 110. Accordingly, it is possible to
prevent the accommodating section 110 from being attached to the sealing bar.
[0195] The sealing-bar attachment-preventing portion 170, the first temperature control
space forming member 231 and the second temperature control space forming member 232
may be all maded of the same material. For example, the sealing-bar attachment-preventing
portion 170, the first temperature control space forming member 231 and the second
temperature control space forming member 232 may be made of the plastic film where
the PET film having a thickness of 12
µm and the CPP film having a thickness of 60
µm are combined.
[0196] To heat or cool the temperature controllable object, a user grips the grip portion
150 and applies force to the liquid reactant entrance 237, thereby opening the first
temperature control space 234. Further, the liquid reactant is inserted in the opened
first temperature control space 234. The liquid reactant put into the first temperature
control space 234 is introduced into a second temperature control space 235 through
a communication space J between the accommodating section 110 and the pouch stand
790. Thus, the exothermic or endothermic reaction can occur between the liquid reactant
and the temperature control agent 131 within even the second temperature control space
235.
[0197] In the case of the pouch 300b according to the twelfth exemplary embodiment, even
though a user opens not both the temperature control spaces 234, 235 but one of them
to insert the liquid reactant, the inserted liquid reactant can be transferred to
the unopened space. Accordingly, it is convenient for a user.
<Thirteenth exemplary embodiment>
[0198] A pouch 100b according to a thirteenth exemplary embodiment as shown in FIG. 24 includes
the accommodating section 110, the temperature controller 130, the sealing portion
240, the grip portion 150, the sealing-bar attachment-preventing portion 170 and the
cutting portion(refer to 180 in FIG. 1).
[0199] As compared with the pouch 100 according to the sixth exemplary embodiment, the pouch
100b according to the thirteenth exemplary embodiment does not include the supporter
160 and has the sealing portion 240 different in shape from the sealing portion 140
according to the sixth exemplary embodiment. Also, as compared with the pouch 100
according to the sixth exemplary embodiment, the pouch 100b according to the thirteenth
exemplary embodiment further includes the pouch stand 790 and thus is standable.
[0200] The sealing portion 240 may be provided to cover the entire of the first accommodating
section film 112 of the accommodating section 110.
[0201] While the sealing portion 140 of the pouch 100 according to the sixth exemplary embodiment
has a predetermined width as shown in FIG. 2, the pouch 100b according to the thirteenth
exemplary embodiment includes the sealing portion 240 provided to cover the entire
of the accommodating section 110.
[0202] Here, the sealing portion 240 may be provided as at least one bwteen the liquid or
solid adhesive tape for adhering the first accommodating section film 112 and the
liquid reactant insertion portion 136, and the easy peel film provided between the
first accommodating section film 112 and the liquid reactant insertion portion 136.
[0203] Here, the solid adhesive tape may include a film type tape, one-side or double-sides
of which the adhesive is applied.
[0204] The easy peel film couples both films thereof with predetermined thermal adhesive
strength when heat of a predetermined temperature range is applied thereto. Here,
the coupling force or adhesive force can be controlled by adjusting a sealing temperature
of sealing up the easy peel film.
[0205] According to the thirteenth exemplary embodiment, the sealing portion 240 is provided
to cover the entire of the first accommodating section film 112, and therefore there
is no need of any separate position adjusting device for interposing the sealing portion
240 between the liquid reactant entrance 136 and the first accommodating section film
112.
<Fourteenth exemplary embodiment>
[0206] A pouch 300c according to a fourteenth exemplary embodiment as shown in FIG. 25 includes
the accommodating section 110; the temperature controller 330; the sealing-bar attachment-preventing
portion 170; the cutting portion (refer to 180 in FIG. 1); the sealing portion 240a
and the grip portion 350.
[0207] As compared with the pouch according to the seventh exemplary embodiment shown in
FIG. 14, the pouch 300c according to a fourteenth exemplary embodiment further includes
the pouch stand 790 and is standable. Also, the sealing portion 240a according to
the fourteenth exemplary embodiment has the sealing portion 340 different in shape
from that of the seventh exemplary embodiment shown in FIG. 14.
[0208] The sealing portion 240a includes a first sealing portion 241 for convering the outer
side, i.e., the front of the first accommodating section film 112; and a second sealing
portion 243 for covering the outer side, i.e., the back of the second accommodating
section film 114.
<Fifteenth exemplary embodiment>
[0209] A pouch 300c according to the fifteenth exemplary embodiment as shown in FIG. 26A
and FIG. 26B includes a accommodating section 110b capable of accommodating the temperature
controllable object; a temperature controller 430; a sealing portion 245; a sealing-bar
attachment-preventing portion 170; a cutting portion (refer to 180 in FIG. 1); and
the grip portion 150.
[0210] The accommodating section 110b includes a first accommodating section film 115 and
a second accommodating section film 117 to form the accommodating space 116 for accommodating
the temperature controllable object.
[0211] The first and second accommodating section films 115, 117 may be made of the same
material as those 112, 114 of the sixth exemplary embodiment.
[0212] The first and second accommodating section films 115, 117 includes communication
holes 115a, 117a for communicating the first temperature control space 434 and the
second temperature control space 436 of the temperature controller 430 with each other
[0213] The temperature controller 430 includes the plurality of temperature control agents
131 respectively arranged at both sides of the accommodating section 110b to heat
or cool the temperature controllable object; a liquid reactant entrance 437 through
which the liquid reactant exothermically or endothermically reacting with the temperature
control agent 131 is insertable; and first and second temperature control space forming
members 431, 432 forming the first and second temperature control spaces 434, 436
to accommodate the plurality of temperature control agents 131, respectively.
[0214] The sealing-bar attachment-preventing portion 170 is as described above to prevent
the accommodating section 110b from being attached to the sealing bar when the upper
end of the accommodating section 110b is thermally adhered by the sealing bar heated
up to a predetermined temperature.
[0215] The sealing-bar attachment-preventing portion 170 may be as described above made
of the same material as that of the first temperature control space forming member
431.
[0216] The sealing portion 245 may be provided to cover the outer side, i.e., the front
side of the first accommodating section film 115, like the sealing portion 240 of
the thirteenth exemplary embodiment.
[0217] The sealing portion 245 may also include a sealing portion communication hole 245a
formed at a position corresponding to the communication holes 115a, 117a in the accommodating
section 110a so that the first temperature control space 434 and the second temperature
control space 436 can communicate with each other.
[0218] Thus, when the grip portion 150 is gripped to space the liquid reactant entrance
437 apart from the accommodating section 110b and the liquid reactant is put into
the first temperature control space 434, the inserted liquid reactant can be introduced
into the second temperature control space 436 via the communication holes 245a, 115a,
117a.
<Sixteenth exemplary embodiment>
[0219] A pouch 100c according to a sixteenth exemplary embodiment as shown in FIG. 27A and
FIG. 27B includes the accommodating section 110 accommodating the temperature controllable
object; the temperature controller 130; the sealing portion 140; the grip portion
150; the pouch stand 790 and a spout cap 170.
[0220] The pouch 100c according to the sixteenth exemplary embodiment does not includes
the cutting portion 180, the supporter 160 and the sealing-bar attachment-preventing
portion 170 as compared with the pouch according to the sixth exemplary embodiment.
[0221] The pouch 100c according to the sixteenth exemplary embodiment includes the spout
cap 170 instead of the cutting portion (refer to 180 in FIG. 1). If there is the cutting
portion (refer to 180 in FIG. 1) like the sixth exemplary embodiment, a user cuts
the cutting portion (refer to 180 in FIG. 1) and opens the accommodating section 110,
thereby taking in or using the temperature controllable object 10a filled therein.
On the other hand, in the eleventh exemplary embodiment, a user opens the spout cap
170 instead of cutting the cutting portion (refer to 180 in FIG. 1) and then takes
in the temperature controllable object 10a.
[0222] Here, the spout cap 170 may be replaced by a straw hole (not shown) for receiving
a straw and and a soft tape attached to the hole. In this case, a user puts the straw
through the tape and takes in the temperature controllable object 10a in the accommodating
section 110 through the hole.
[0223] The temperature controllable object 10a may include coffee, soupe or the like beverage,
or food.
[0224] Meanwhile, a method of manufacturing the pouch 100a according to the fourteenth exemplary
embodiment will be described below with reference to FIG. 25 and FIG. 28A to FIG.
28C.
[0225] First, the first temperature control space forming member 331, the first sealing
portion 241 and the first accommodating sectionfilm 112 are combined to form the front
side, i.e., the outer skin. Here, the sealing-bar attachment-preventing portion 170
may also be placed on an upper side of the first sealing portion 241.
[0226] If the first temperature control space forming member 331 and the sealing-bar attachment-preventing
portion 170 are made of the same PET film, the PET films are cut and arranged at predetermined
positions before combination, so that the first temperature control space forming
member 331 and the sealing-bar attachment-preventing portion 170 can be arranged.
[0227] A back outer skin opposite to the front outer skin is formed with the pouch stand
790 therebetween. The back outer skin is symmetrical to the front outer skin with
the pouch stand 790 therebetween, and the second accommodating section film 114, the
second sealing portion 243 and the second temperature control space forming member
332 are arranged in sequence from the upside.
[0228] Here, the temperature control agent 131 may be inserted between the first sealing
portion 241 and the first temperature control space forming member 331 and between
the second sealing portion 243 and the second temperature control space forming member
332.
[0229] Meanwhile, the first and second temperature control space forming members 331, 332,
the temperature control agent 131 and the sealing-bar attachment-preventing portion
170 may be wored by the following process. That is, in more detail, the pouch stand
790, the first and second accommodating section films 112, 114 and the first and second
sealing portions 241, 243 are first sealed in the form of an envelope except their
upper regions, and then the first and second temperature control space forming members
331, 332 and the sealing-bar attachment-preventing portion 170 are arranged on the
outer side of the envelop and then secondarily sealed up.
[0230] In the state of being combined as shown in FIG. 28A, the edges of the other regions
D2, D3 and D4 are sealed up except the edge D1 corresponding to an upper opening of
the contents-accommodating space as shown in FIG. 28B. At this time, the sealing may
be achieved by thermal adhesion using the sealing bar heated within a predetermined
second temperature range. Thus, the first and second accommodating section films 112,
114 form the contents-accommodating space 116.
[0231] At this time, the predetermined second temperature range may be 230°C or higher and
300°C or lower.
[0232] Next, the upper end region L of the the first temperature control space forming member
331 is thermally adhered to the first sealing portion 241 and the first accommodating
section film 112 by the sealing bar heated within a predetermined first temperature
range. In more detail, the region to be sealed by the sealing bar is a predetermined
section S5 from a position spaced apart by a predetermined width K1 from the upper
end 331a of the first temperature control space forming member 331 toward the temperature
control agent 331.
[0233] Here, the sealing of the sealing bar is not performed up to a section spaced part
by a predetermined width w from the upper end 331a of the first temperature control
space forming member 331. This region corresponds to the foregoing grip portion 150.
The center region upper end portion 331b of the temperature control space forming
member 331 is provided to protrude so that the grap portion (see 150 in FIG. 1) can
be formed in the form of the protruded center portion.
[0234] Here, the first temperature range may be 150°C or higher and 220°C or lower.
[0235] Sinced the first temperature range is lower than the second temperature range, the
sealing region J sealed up by the sealing bar of the first temperature control space
forming member 331 within the first temperature range has a thermal adhesive strengthsealing
weaker than those of the edge regions (refer to D1, D2, D3, D4 in FIG. 28B) sealed
up by the sealing bar of the second temperature range.
[0236] The sealing region J of the first temperature control space forming member 331 corresponds
to the foregoing liquid reactant entrance 337. Accordingly, a user can easily open
the liquid reactant entrance 337 having a relatively weak thermal adhesive strength.
[0237] After sealing up the sealing region J of the first temperature control space forming
member 331, the edge region D1 is not being sealed but opened so that the temperature
controllable object can be inserted through such an opend opening.
[0238] Next, after the temperature controllable object is completely inserted, the opened
edge region D1 is thermally adhered by the sealing bar heated within the second temperature
range.
[0239] At this time, the predetermined second temperature range may be 230°C or higher and
300°C or lower.
[0240] Meanwhile, the method of thermllay adhering the second temperature control space
forming member 332 to the second accommodating section film 114 and the second sealing
portion 243 is the same as that for the first temperature control space forming member
332, and the repetitive descriptions thereof will be avoided.
[0241] Meanwhile, in the foregoing, the temperature control agent 131 is inserted between
the first temperature control space forming member 331 and the first sealing portion
241 and the edges D2, D3, D4 are sealed up, and then the temperature controllable
object is filled in the accommodating space between the first and second accommodating
section films 112, 114.
[0242] However, in the case where the edges D2, D3, D4 of the first and second accommodating
section films 112, 114 first undergo the sealing work, and then the first and second
sealing portions 241, 243 and the first and second temperature control space forming
members 331, 332 undergo the following sealing process, the contents-accommodating
space is already formed, and therefore the accommodating space is firste filled with
the temperature controllable object and then filled with the temperature control agent
131. Accordingly, the sealing work for the edges D2, D3, D4 may be performed once
again. That is, the contents filling and sealing process and the temperature control
agent filling and sealing process may be exchanged in order.
[0243] Here, if the temperature controllable object (i.e., the contents) is coffee, soup
or the like liquid food needed to be sterilized, the contents filling and sealing
processes may be previously performed to the temperature control agent filling the
sealing process so as to make the contents filling process more safety.
[0244] The sealing of the upper end edge D1 of the pouch may be performed after the temperature
controllable object (i.e., the contents) is filled. As necessary, the upper end edge
D1 may not be sealed if the temperature controllable object (i.e., the contents) is
hardly affected by an external environment or if there is no need of sealing the contents-accommodating
space because its expiration date is short.
[0245] Meanwhile, a method of manufacturing the pouch will be described below with reference
to FIG. 18 to FIG. 21 and
[0247] First, the contents-accommodating section 110 capable of accommodating the contents
therein, the temperature control space forming member 132 arranged in at least one
side between the front and back sides of the contents-accommodating section 110 and
having the upper end lower than that of the contents-accommodating section, and at
least one sealing portion 140 inserted between the temperature control space forming
member and the contents-accommodating section are combined (S10).
[0248] Then, the upper end region of the temperature control space forming member 132 with
the sealing portion 140 is thermally adhered to the contents-accommodating section
110 by the sealing bar heated at the first temperature (S20). Here, the upper end
region, which corresponds to the liquid reactant entrance 136 of the temperature control
space forming member 132, seals up the liquid reactant entrance 136.
[0249] Here, the first temperature may be 150°C or higher and 220°C or lower. If the first
temperature for heating the sealing bar to thermally adhere the upper end region is
lower than 150°C, the thermal adhesive strength of the liquid reactant entrance 136
is so weak that the sealing of the temperature control space 134 is deteriorated between
the temperature control space forming member 131 and the contents-accommodating section
110, thereby allowing foreign materials (e.g., moisture or the like) to be introduced.
[0250] On the other hand, if the first temperature is higher than 220°C, the thermal adhesive
strength of the liquid reactant entrance 136 is so strong that it is difficult for
a user to open the temperature control space 134.
[0251] Next, the temperature control agent 131 is inserted in the temperature control space
forming member 131 and the contents-accommodating section 140 (S30).
[0252] Next, the left and right sides and the lower sides of the temperature control space
forming member 132 filled with the temperature control agent 131 are thermally adhered
to the contents-accommodating section 110 by the sealing bar heated up to the second
temperature (S40).
[0253] Here, the second temperature may be 230°C or higher and 300°C or lower.
[0254] Here, the first temperature is lower than the second temperature. As described above,
this is to make a user easily open the temperature control space 134 while keeping
its sealing as the thermal adhesive strength of the liquid reactant entrance 136 expected
to be open is weaker than the other portions (i.e., the left, right and lower edges).
[0255] Meanwhile, the combination of S10 includes primarily sealing the left, right and
lower edges of the contents-accommodating section 110 and the sealing portion 140
so that the upper end of the contents-accommodating section 110 can be open, by combining
the contents-accommodating section 110 and the sealing portion 140 (S11); and combining
the temperature control space forming member 132 to the front side of the primarily
sealed sealing portion 140 (S12). Thus, the accommodating space 116 is formed to accommodate
the temperature controllable object 10 in the state that the upper end of the contents-accommodating
section 110 is opend.
[0256] Here, in the primarily sealing (S11), only the contents-accommodating section 110
may be combined and sealed without the sealing portion 140. In this case, the sealing
portion 140 together with the temperature control space forming member 132 may be
sequentially combined to the contents-accommodating section 110 in the combination
(S12).
[0257] Meanwhile, the operation of putting the temperature controllable object 10 in the
accommodating space 116 formed by the primarily sealing may be performed between the
primarily sealing (S11) and the combination of the temperature control space forming
member 132 (S12).
[0258] As necessary, the operation of putting the temperature controllable object 10 may
be peformed after the operation S40 of thermally adhering the left, right and lower
end regions of the temperature control space forming member 132.
<Seventeenth exemplary embodiment>
[0259] As shown in FIG. 30 to FIG. 32, a pouch 2100 according to the seventeenth exemplary
embodiment includes a temperature controller 2130 provided with a contents-accommodating
section 2110, a temperature control agent 2131 and a liquid reactant container 2190;
a sealing portion 2140, a grip portion 2150 and a pouch cutting portion 2180.
[0260] The contents-accommodating section 2110 is provided to accommdate the contents, that
is, the temperature controllable object 10.
[0261] Here, Here, the temperature controllable object 10 includes various instant food
such as the retort pouch. For example, the contents may include food such as boiled
rice, Bibimbap, soup, stew or dry milk; a pad containing medicine for taking a hot
massage or a cold massage, or a mask pad containing beauty ingredients. Besides, the
contents may be varied as long as it has to be instantly heated or cooled.
[0262] The contents-accommodating section 2110 includes a first accommodating section film
2112 and a second accommodating section film 2114. Between the first accommodating
section film 2112 and the second accommodating section film 2114 is formed an accommodating
space 2116 for accommodating the temperature controllable object 10. Here, the first
accommodating section film 2112 and the second accommodating section film 2114 may
be made of a heat resistant plastic film.
[0263] In more detail, the contents-accommodating section 2110 may include the plastic film
such as polyethylene (PE), polypropylene (PP), or a polyethyelene terephthalate (PET).
[0264] Of course, the first accommodating section film 2112 and the second accommodating
section film 2114 constituting the contents-accommodating section 2110 may be made
of well-known synthetic resin films of various materials.
[0265] For example, the first accommodating section film 2112 may include a CPP film having
a thickness of 60
µm, an aluminum film having a thickness of 9
µm, or a combination film between a nylon film having a thickness of 15
µm and a CPP film having a thickness of 60
µm. Of course, this is nothing but illustrative. The first accommodating section film
112 may include a combination film of various materials, or as necessary include a
film of a single material. The second accommodating section film 2114 may be made
of the same material as that of the first accommodating section film 2112.
[0266] The first accommodating section film 2112 and the second accommodating section film
2114 form an envelope shape as the other side and both sides connecting one side and
the other side are adhered and sealed so as to open one side. As the first accommodating
section film 2112 and the second accommodating section film 2114 are adhred, the accommodating
space 2116 accommodating the temperature controllable object 10 is formed. Trough
an opening side of the accommodating section 2110, the temperature controllable object
10 is filled in the accommodating space 2116, and the opening side is sealed up by
the sealing-bar attachment-preventing portion 2170 to be described later after the
temperature controllable object 10 is completely filled.
[0267] The temperature controller 2130 may be formed at one side between both sides of the
accommodating section 2110.
[0268] The temperature controller 2130 according to the seventeenth exemplary embodiment
as shown in FIG. 30 to FIG. 32 and FIG. 34 includes the temperature control agent
2131 arranged in a temperature control space 2134 provided in at least one side between
front and back sides of the contents-accommodating section 2110 and heating or cooling
the temperature controllable object (i.e., the contents); a liquid reactant container
2190 arranged in the temperature control space 2134 and containing the liquid reactant
for exothermically or endothermically reacting with the temperature control agent
2131; and a temperature control space forming member 2132 forming the temperature
control space 2134 in which the exothermic or endothermic reaction occurs.
[0269] The temperature control agent 2131 includesthe reactant 2131b and the reactant accommodating
section 2131a. The temperature control agent 2131 according to the seventeenth exemplary
embodiment is arranged at one side between both sides of the contents-accommodating
section 2110. The temperature control agent 2131 accordingto according to an exemplary
embodiment is arranged at a side facing the first accommodating section film 2112.
The temperature control agent 2131 reacts with the liquid reactant w such as water
inserted from the outside.
[0270] The reactant 2131b includes the heating element or the heat absorption agent in accordance
with whether to heat or cool the temperature controllable object 10 accommodated in
the accommodating section 2110. The reactant 2131b may include at least one as the
heating element among calcium oxide (CaO), calcium hydroxide (Ca(OH)2), magnesium
chloride (MgCl2), iron (Fe) and aluminum (Al). Here, the reactant 131b may be replaced
or changed by other substances as long as it can exothermally react with the liquid
reactant w.
[0271] On the other hand, the reactant 2131b may include at least one as the heat absorption
agent among ammonium nitrate (NH4NO3), sodium acetate (CH3COONa) and (urea). Of course,
the reactant 131b may be replaced or changed by other substances as long as it can
endothermally react with the liquid reactant w.
[0272] The reactant accommodating section 2131a accommodates the reactant 2131b. The reactant
accommodating section 131a includes a body 2131a1 and a partition 2131a2. The reactant
accommodating section 2131a is provided as an absorption fabric to quickly absorb
the liquid reactant w. As necessary, the reactant accommodating section 2131a may
be made of not the absorption fabric but other substances.
[0273] The body 2131a1 is provided to accommodate the reactant 2131b. Here, the body 2131a1
according to an exemplary embodiment is partitioned into four accommodating regions
by the partition 2131a2. Thus, the reactant 2131b is accommodated in each of the plurality
of accommodating regions partitioned by the partition 2131a2, thereby preventing the
reactant 2131b from being leaning by its own weight. Also, the reactant 2131b is accommodated
in each of the plurality of accommodating regions, and thus the divided reactant 2131b
individually contacts the liquid reactant W1, thereby making a temperature control
reaction quickly.
[0274] The temperature control space forming member 2132, as shown in FIG. 30, is arranged
in a lower side rather than an upper end of the contents-accommodating section 2110.
In more detail, the upper end of the temperature control space forming member 2132
is lower than the upper end of the contents-accommodating section 2110.
[0275] The temperature control space forming member 2132 includes a liquid reactant entrance
2136 through which the liquid reactant container 2190 is taken out from the temperature
control space 2134 and the liquid reactant W1 contained in the liquid reactant container
2190 is put in.
[0276] The temperature control space forming member 2132 together with the first accommodating
section film 2112 forms the temperature control space 2134 to accommodate the temperature
control agent 2131 and the liquid reactant container 2190. The temperature control
space 2134 is a space where the exothermic or endothermic reaction occurs when the
liquid reactant W1 contained in the liquid reactant container 2190 is inserted, and
has a margin space to accommodate the liquid reactant W1 in addition to the temperature
control agent 2131.
[0277] Here, the temperature control space forming member 2132 may be made of a transparent
synthetic resin film so that the liquid reactant W1, the liquid reactant container
2190 and the temperature control agent 131 to be inserted can be checked by naked
eyes. Of course, the temperature control space forming member 2132 may be made of
the transparent synthetic resin film with regard to only a part that can be checked
by naked eyes. Of course, the temperature control space forming member 132 may be
partially made of the transparent synthetic resin film checkable by naked eyes. Of
course, checkability by naked eyes is optional, and thus an opaque film may be used
as necessary. The temperature controller 2130 may be lower than the accommodating
section 2110 so that an upper opening of the accommodating section 2110 for inserting
the temperature controllable object 10 can be exposed. According to an exemplary embodiment,
the height of the temperature control space forming member 132 may be eight tenth
with respect to the height of the accommodating section 110.
[0278] The temperature control space forming member 2132 may have an upper end lower than
that of the contents-accommodating section 2110.
[0279] The temperature control space forming member 2132 according to an exemplary embodiment
may be arranged to have a height from the lower end of the contents-accommodating
section 2110 to the upper end of the temperature control space forming member 2132,
which is lower by 20% than the hight from the same position to the upper end of the
contents-accommodating section 2110.
[0280] The temperature control space forming member 2132 may be made of the plastic film.
For example, the temperature control space forming member 132 may be the plastic film
where a PET film having a thickness of 12
µm and a CPP film having a thickness of 60
µm are combined. Of course, this is nothing but illustrative. Alternatively, the plastic
film may be a combination film where films of various well-known substances are combined
or a single material film.
[0281] The liquid reactant container 2190 as shown in FIG. 34 includes a liquid reactantthe
accommodating section 2191 forming the accommodating space to accommodate the liquid
reactant W1; a liquid reactant outlet 2193 through which the accommodated liquid reactant
flows out; and a liquid reactant container cutting portion 2195 for cutting the liquid
reactant outlet 2193.
[0282] The liquid reactant container 2190 may be made of soft or hard plastic film. According
to an exemplary embodiment, the liquid reactant container 2190 may be an envelope
made of a soft plastic film. As necessary, the liquid reactant container 2190 may
be achieved by sealing a hard plastic film (or plate) and a soft plastic film with
each other.
[0283] The liquid reactant outlet 2193 may have a width narrower than the liquid reactantthe
accommodating section 2191. Thus, through the liquid reactant outlet 2193 having a
relatively narrow width, the liquid reactant W1 can easily flow out in a predetermined
direction.
[0284] The liquid reactant container cutting portion 2195 may include a notch formed at
one side of the liquid reactant outlet 2193. The notch may be replaced by a cutting
groove formed along the cutting direction. Besides, the notch may have various shapes
as long as it can be cut with a hand gripping the liquid reactant outlet 2193.
[0285] The liquid reactant container cutting portion 2195 may be cut when a user artificially
applies shear force in a width direction with his/her two hands. Thus, it is possible
to prevent the liquid reactant container cutting portion 2195 from being cut by mistake
while carrying the pouch 22100a.
[0286] The liquid reactant insertion portion 2136 is coupled to the contents-accommodating
section 2110 by the sealing portion 2140 to be described later, and closes the temperature
control space 2134.
[0287] Also, the liquid reactant insertion portion 2136 is provided to open the temperature
control space 2134 closed by the sealing portion 2140 so that the liquid reactant
container 2190 can be taken out and the liquid reactant W1 contained in the liquid
reactant container 2190 can be put in.
[0288] In more detail, the liquid reactant insertion portion 2136 can be spaced apart from
the sealing portion 2140 or the first accommodating section film 2112 when force of
not less than a predetermined magnitude is applied, in order to take out the liquid
reactant container 2190 from the temperature control space 2134 and put the liquid
reactant W1 of the liquid reactant container 2190. Thus, the upper side of the temperature
control space 2134 is opened so that the liquid reactant W1 can be put in the temperature
control space 2134.
[0289] The sealing portion 2140 seals up the accommodating section 2110 and the temperature
controller 2130, specifically, the liquid reactant insertion portion 2136, thereby
sealing up the temperature control space 2134. Here, the sealing portion 2140 seals
up the accommodating section 2110 and the liquid reactant insertion portion 2136 with
predetermined intensity of adhesion so that the temperature control space 2134 can
be opened when force of not less than a predetermined magnitude is applied for spacing
the liquid reactant insertion portion 2136 apart from the accommodating section 2110.
That is, when the liquid reactant insertion portion 2136 is pulled by force stronger
than the adhesive strength of the sealing portion 2140, the temperature control space
2134 is opened. On the other hand, if force of not less than a predetermined magnitude
is not applied, the sealing due to the sealing portion 2140 is maintained, thereby
maintaining the sealed state of the temperature control space 2134
[0290] Here, the sealing portion 2140 may have an adhesive strength of not less than 2200gf/cm
2 and not more than 5kgf/ cm
2. In experimental results, if the adhesive strength is less than 2200gf/cm
2, the sealing may not be maintained when the temperature controllable object 10 is
filled and then heated to expand the temperature control space 2134. On the other
hand, the adhesive strength is more than 5kgf/cm
2, it is difficult for a regular adult to open the temperature control space 2134.
[0291] Preferably, the sealing portion 2140 may have a adhesive strength of 500gf/cm
2 ∼ 3kgf/cm
2.
[0292] According to an exemplary embodiment, the sealing portion 2140 is placed on the planar
surface of the first accommodating section film 2112, and seals up between the liquid
reactant insertion portion 136 of the temperature controller 130and the first accommodating
section film 2112. Thus, the sealing portion 2140 seals up between the first accommodating
section film 2112 and the liquid reactant insertion portion 2136, and prevents foreign
materials from being introduced into the temperature control space 134 while the temperature
controllable object 10 is filled in the accommodating space 2116 of the accommodating
section 2110 and then sterilized. Such sterilization is essential when a retort pouch
is produced by putting stew, soup, boiled rice and the like instant foods into the
pouch 2100.
[0293] Meanwhile, the sealing portion 2140 may be released from the sealing with the liquid
reactant insertion portion 2136 when force of not less than a certain magnitude is
applied for inserting the liquid reactant W1 into the temperature control space 1134
as temperature control is required for the temperature controllable object 10. Then,
the liquid reactant insertion portion 2136 is opened to open the temperature control
space 2134, so that the liquid reactant w can be inserted in the temperature control
space 2134. Accordingly, the exothermic or endothermic reaction occurs between the
temperature control agent 2131 and the liquid reactant W1.
[0294] Here, the sealing portion 2140 may include at least one among liquid adhesive for
adhereing the first accommodating section film 2112 and the liquid reactant insertion
portion 2136, a solid adhesive tape, and an easy peel film provided between the first
accommodating section film 2112 and the liquid reactant insertion portion 2136.
[0295] Here, the solid adhesive tape may be a film type tape, one or both sides of which
the adhesive is applied to.
[0296] The easy peel film couples both films thereof with predetermine thermal adhesion
when heat of a predetermined temperature range is applied. Here, the coupling force
or adhesion may be controlled by adjusting the temperature range of heat applied to
the easy peel film.
[0297] Here, the adhesive strength due to the sealing portion 2140 between the liquid reactant
entrance 2136 and the accommodating section 2110 is weaker than contact strength between
the temperature control space forming member 132 and the accommodating section 2110
besides the liquid reactant entrance 2136.
[0298] In more detail, the liquid reactant entrance 2136 is expected to be opened so as
to insert the liquid reactant in the temperature control space 2134, and therefore
the adhesive strength of the partial sealing portion C10 between the liquid reactant
entrance 2136 and the accommodating section 2110 may be weaker than the adhesive strength
of the partial sealing portion C9 in a lateral edge between the temperature control
space forming member 2132 and the accommodating section 2110. This may be achieved
by changing the temperature range of the sealing bar used when sealing the partial
sealing portions C9, C10. Such temperature range will be described later.
[0299] The upper end region of the temperature control space forming member 2132 and the
contents-accommodating section 2110 between which the sealing portion 2140 is interposed
are may be thermally adhered by the sealing bar heated at the first temperature. Here,
the upper end region, which corresponds to the liquid reactant entrance 2136 of the
temperature control space forming member 2132, seals up the liquid reactant entrance
2136.
[0300] Here, the first temperature may be 150°C or higher and 220°C or lower. If the first
temperature of the sealing bar thermally adhering the upper end regions is lwer than
150°C, the thermal adhesive strength of the liquid reactant entrance 2136 is so weak
that the sealability of the temperature control space 2134 between the temperature
control space forming member 2131 and the contents-accommodating section 2110 is deteriorated
to thereby allowing external foreign materials (e.g., moisture or the like) to be
introduced therein.
[0301] On the other hand, if the first temperature is higher than 220°C, the thermal adhesive
strength of the liquid reactant entrance 2136 is so strong that it is difficult for
a user to open the temperature control space 2134.
[0302] Meanwhile, the partial sealing portion C9 of the left, right and lower edge regions
between the temperature control space forming member 2132 and the contents-accommodating
section 2110 may be thermally adhered by the sealing bar heated at the second temperature.
[0303] Here, the second temperature may be 230°C or higher and 2300°C or lower.
[0304] Here, the first temperature is lower than the second temperature. As described above,
this is to make a user easily open the temperature control space 134 while keeping
its sealing as the thermal adhesive strength of the liquid reactant entrance 136 expected
to be open is weaker than the other portions (i.e., the left, right and lower edges).
[0305] Meanwhile, the grip portion 2150 is provided to allow a user to easily grip the liquid
reactant insertion portion 2136 of the temperature controller 2130. The grip portion
2150 may be extended from the liquid reactant insertion portion 2136 and may be formed
integrally with the liquid reactant insertion portion 2136.
[0306] The grip portion 2150 may protrude from the liquid reactant insertion portion 2136.
The grip portion 2150 may be provided in the center region of the liquid reactant
insertion portion 2136. The grip portion 2150 protrudes from the center region of
the liquid reactant insertion portion 2136 and is gripped by a user. In particular,
the grip portion 2150 is gripped by a user and transfers a user's force to the liquid
reactant insertion portion 2136 so that the liquid reactant insertion portion 2136
can be released from the accommodating section 2110. To make a user easily grip the
grip portion 2150 and efficiently transfer his/her force, the grip portion 2150 may
protrude from the center portion of the liquid reactant insertion portion 2136.
[0307] Of course, the grip portion 2150 be plurally provided at both sides of the liquid
reactant insertion portion 136.
[0308] As shown in FIG. 31, the upper end portions of the first and second accommodating
section films 2112, 2114 are not sealed so that the temperature controllable object
10 can be put into the contents-accommodating section 2110 along the inserting direction
B1 in the state that the upper portion of the contents-accommodating section 2110
is opened.
[0309] To heat or cool the temperature controllable object 10 accommodated in the contents-accommodating
section 2110, as shown in FIG. 33, a user first grips the grip portion 2150 and pulls
the liquid reactant entrance 2136 in a direction of Fl, thereby spacing it apart from
the accommodating section 2110. At this time, if force of not less than a predetermined
magnitude is applied for spacing the liquid reactant entrance 2136 apart from the
accommodating section 2110, that is, stronger than the adhesive strength due to the
sealing portion 2140, the liquid reactant entrance 2136 is opened. As described above,
the thermal adhesive strength in the sealing region C10 due to the sealing portion
150 is weaker than the thermal adhesive strength of the edge portion C9 of the accommodating
section 2110, and therefore the liquid reactant entrance 2136 can be more easily opened
than other portions.
[0310] In the state that the temperature control space 2134 is being opened, the liquid
reactant container 2190 is taken out from the temperature control space 2134 and the
liquid reactant container 2190 is cut using the liquid reactant container cutting
portion 2195 of the liquid reactant container 2190. From the cut liquid reactant container
2190, the liquid reactant is put into the temperature control space 2134. Accordingly,
the exothermic or endothermic reaction occurs between the liquid reactant and the
temperature control agent 2131 within the temperature control space 2134, so that
the temperature controllable object 10 accommodated in the accommodating space 2116
can be heated or cooled. As a proper amount of the liquid reactant contained in the
liquid reactant container 2190 reacts with the temperature control agent 2131, the
optimal exothermic or endothermic reaction may occur.
[0311] After a lapse of predetermined time, a user uses the grip portion 2180 to cut open
the upper end of the accommodating section 2110. Thus, a user takes in, takes out
or uses the heated or coold temperature controllable object 10 through the accommodating
section 2110 having the opened upper portion.
[0312] Meanwhile, the foregoing illustrates that the lateral edges D6 of the first accommodating
section film 2112 and the second accommodating section film 2114 of the contents-accommodating
section 2110 are directly sealed up. As necessary, the cross section of the lateral
edges may be creased like

so that a user can more easily grip the lateral side of the pouch 2100. This may
be achieved by interposing a separate fim between the lateral edges of the first accommodating
section film 2112 and the second accommodating section film 2114 and thus broadening
both edges.
<Eighteenth exemplary embodiment>
[0313] A pouch 2200 according to the eighteenth exemplary embodiment, as shown in FIG. 35
to FIG. 37 includes a contents-accommodating section 2210 having a contents-accommodating
space S6 to accommodate the contents; a temperature controller 2220 provided in at
least one side between the front and back sides of the contents-accommodating section
2210 to heat or cool the contents-accommodating section 2210; and a sealing portion
2230 sealing up a liquid reactant entrance 2222 communicating the temperature control
spaces S7, S8 in the temperature controller 2220.
[0314] The contents-accommodating section 2210 includes a first accommodating section film
2211 and a second accommodating section film 2213 to form the contents-accommodating
space S6.
[0315] The first accommodating section film 2211 and the second accommodating section film
2213 may be made of a plastic film. In more detail, the plastic film may include polyethylene
(PE), polypropylene (PP), or a polyethyelene terephthalate (PET). Besides, the first
accommodating section film 2211 and the second accommodating section film 2213 may
be made of well-known synthetic resin films of various materials.
[0316] The temperature controller 2220 couples with the contents-accommodating section 2210,
in more detail, couples with the contents-accommodating section 2210 so as to form
the temperature control spaces S7, S8 provided in at least one side between the front
and rear sides with respect to the contents-accommodating space S6.
[0317] FIG. 35 to FIG. 37 illustrate that the temperature control spaces S7, S8 are formed
in front and back, but not limited thereto. As necessary, the temperature control
spaces S7, S8 may be formed at only one side.
[0318] The temperature controller 2220 includes a second front film 2221 coupled in the
front of the contents-accommodating section 2210 and forming the temperature control
space S7 in a front side; and a second back film 2224 coupled in the back of the contents-accommodating
section 2210 and forming the temperature control space S8 in a back side.
[0319] The first temperature control space forming member 2221 and the second temperature
control space forming member 2224 may be made of a plastic film such as polyethylene
(PE), polypropylene (PP), or a polyethyelene terephthalate (PET). Besides, the first
temperature control space forming member 2221 and the second temperature control space
forming member 2224 may be made of well-known synthetic resin films of various materials.
[0320] Here, the temperature control spaces S7, S8 are isolated from the contents-accommodating
space S6.
[0321] The front and back temperature control spaces S7, S8 can communicate with each other
through a communication space S9. The communication space S9 may be formed by arranging
the contents-accommodating section 2210 so that the lower end portion 2211c of the
contents-accommodating section 2210 can be spaced apart from the lower end portion
D6 of the temperature controller 2220. In this case, the lower end portion D6 of the
temperature controller 2220 is a part where the respective lower end portions of the
first temperature control space forming member 2221 and the second temperature control
space forming member 2224 are coupled by ultrasonic waves or thermal welding. Of course,
coupling between the plastic films may be achieved various well-known methods besides
the foregoing ultrasonic waves or thermal welding.
[0322] Meanwhile, the contents-accommodating section 2210 and the temperature controller
2220 may be coupled with each other at left and right end portions D6, D7 by ultrasonic
waves or thermal welding.
[0323] The temperature controller 2220 includes a plurality of temperature control agents
2223, 2225 respectively arranged in the plurality of temperature control spaces S7,
S8.
[0324] As described above, if the temperature control spaces , S8 are formed at only one
side between front and back sides, the temperature control agents 2223, 2225 may be
arranged at only one corresponding side.
[0325] Here, the temperature control agents 2223, 2225 includes heating elements 2223a,
2225a to exothermically react with the liquid reactant, and absorption fabrics 2223b,
2225b surrounding the heating elements 2223a, 2225a and absorbing the liquid reactant
to make the exothermic reaction smoothly.
[0326] As necessary, the absorption fabrics 223b, 225b may be omitted.
[0327] Also, a heat absorption agent endothermically reacting with the liquid reactant may
be used instead of the heating elements 2223a, 2225a. The heating element and the
heat absorption agent react with the liquid reactant to heat and cool the contents
accommodated in the contents-accommodating space S6.
[0328] The heating element may include at least one among calcium oxide, calcium hydroxide,
magnesium chloride, iron, and aluminum. Of course, the foregoing substances may be
replaced or changed by other substances as long as it can react with the liquid reactant.
[0329] The heat absorption agent may include at least one of ammonium nitrate (NH4NO3),
sodium acetate and urea.
[0330] Here, the plurality of temperature control agents 2223, 2225 may all include only
the heating elements, or only the heat absorption agent.
[0331] As necessary, in the plurality of temperature control agents 2223, 2225, the front
temperature control agent 2223 may include only the heating element, and the back
temperature control agent 2225 may include only the heat absorption agent. In this
case, the front and back temperature control spaces S7, S8 may not communicate with
each other but isolated from each other with the contentsaccommodating space S6 therebetween.
[0332] The temperature controller 2220 may further include the liquid reactant container
2190 arranged in the temperature control spaces S7, S8.
[0333] If the temperature control spaces S7, S8 communicate with each other, the liquid
reactant container 2190 may be provided in only the temperature control space S7 formed
with the liquid reactant entrance 2222 to be described later. If the liquid reactant
entrances 2222 are respectively formed at both sides of the plurality of temperature
control space S7, S8, the liquid reactant container 2190 may be provided in each of
the temperature control spaces S7, S8.
[0334] The temperature controller 2220 may further include the liquid reactant entrance
2222 through which the liquid reactant container 2190 is taken out from the temperature
control spaces S7, S8 and the liquid reactant (refer to W1 of FIG. 34) of the liquid
reactant container 2190 is put in.
[0335] The liquid reactant entrance 2222 is sealed up by the sealing portion 2230 so as
to be openable.
[0336] Also, the liquid reactant entrance 2222 is arranged at a lower side of the contents-accommodating
section 2210 rather than an upper end thereof. That is, an upper edge of the liquid
reactant entrance 2222 is lower than the upper end of the contents-accommodating section
2210 so that a user can easily check the position of the liquid reactant entrance
2222 with his/here naked eyes.
[0337] The liquid reactant entrance 222 may be formed as a partial upper end section G1
of the first temperature control space forming member 2221 of the temperature controller
2220 is not coupled with the first accommodating section film 2211. At this time,
the first temperature control space forming member 2221 of the remaining upper end
section D8 may be permanently sealted up with the first accommodating section film
2211.
[0338] Here, the liquid reactant entrance 222 the partial upper end section G of the second
front film 221. As necessary, the liquid reactant entrance 222 may be formed in the
entire upper end section of the second front film 221.
[0339] Here, the drawings illustrate the liquid reactant entrance 2222 is formed in the
partial upper end section G1 of the first temperature control space forming member
2221. As necessary, the liquid reactant entrance 222 may be formed in the entire upper
end section of the first temperature control space forming member 2221.
[0340] Also, the height of the liquid reactant entrance 2222 from the lower end of the pouch
may be relatively greater than that of the remaining section D8 of the first temperature
control space forming member 2221 from the lower end of the pouch 2200. Of course,
the liquid reactant entrance 2222 may have the same height as the remaining section
D8 of the first temperature control space forming member 2221.
[0341] The pouch 2200 may include a grip portion 2222a extended frontward so that a user
cen easily grip the liquid reactant entrance 2222 with his/her hand. Thus, a user
can easily grip and open the liquid reactant entrance 2222.
[0342] Here, the grip portion 2222a may be as shown in FIG. 37 formed to be folded down
from the first accommodating section film 2211.
[0343] As necessary, instead of the grip portion 2222a of FIG. 37, the upper end of the
first temperature control space forming member 2221 may be provided as it is spaced
apart from the contents-accommodating section 2210, specifically from the first accommodating
section film 2211 by a predetermined space K. Thus, a user puts his/her fingers in
the space and broadens the liquid reactant entrance 2222, thereby opening the liquid
reactant entrance 2222.
[0344] Meanwhile, the sealing portion 2230 seals up the liquid reactant entrance 2222 as
long as the liquid reactant entrance 2222 is not spaced from the contents-accommodating
section 2210 by force of not less than a predetermined magnitude. Thus, it is possible
to prevent foreign materials from entering the liquid reactant entrance 2222 while
the contents is put into and sterilized in the contents-accommodating section S6 of
the pouch 2200. Such sterilization is essential when a retort pouch is produced by
putting stew, soup, boiled rice and the like instant foods into the pouch 2200.
[0345] Accordingly, the pouch 2200 according to an exemplary embodiment facilitates the
manufacture of the retort pouch.
[0346] As shown in FIG. 37, the sealing portion 2230 may be provided between the first temperature
control space forming member 2221 and the first accommodating section film 2211 at
a side lower than the grip portion 2222a of the liquid reactant entrance 2222.
[0347] The sealing portion 2230 may be provided to allow opening between the first accommodating
section film 2211 and the first temperature control space forming member 2221 when
force of not less than a predetermined magnitude is applied thereto. In other words,
if external force of not less than a predetermined magnitude is applied, the sealing
portion 2230 may open the liquid reactant entrance 2222. Thus, if a user grips and
then pulls the grip portion 2222a by force of not less than a predetermined magnitude,
the liquid reactant entrance 2222 is opened.
[0348] A user takes out and cuts the liquid reactant container 2190 from the open liquid
reactant entrance 2222, and puts the liquid reactant (refer to W1 of FIG. 34, for
example, water) into the temperature control space S7, thereby heating or cooling
the contents accommodated in the contents-accommodating space S6.
[0349] Here, the liquid reactant (refer to W1 of FIG. 34) put into the temperature control
space S7 causes the exothermic or endothermic reaction while moving to another temperature
control space S8 through the communication space S9.
[0350] Also, since the liquid reactant entrance 2222 is easily opened to put the liquid
reactant, it is convenient for a user.
[0351] The sealing portion 2230 may be made of the same material as the sealing portion
2140 of the foregoing seventeenth exemplary embodiment. In more detail, the sealing
portion 2230 may include at least one among liquid adhesive, a solid adhesive tape,
and an easy peel film arranged between the first accommodating section film 2112 and
the liquid reactant insertion portion 2136.
[0352] As necessary, the sealing portion 2230 may be formed by fusing the first accommodating
section film 2211 and the first temperature control space forming member through thermal
welding or ultrasonic waves. At this time, the first accommodating section film 2211
and the first temperature control space forming member 2221 may be fused to such an
extent as to be separated from each other when the sealing portion 2230 receives external
force of a predetermined magnitude.
[0353] Of course, the sealing portion 2230 may be varied as long as it can seal up the liquid
reactant entrance and prevent foreign materials, such as liquid (e.g., water), from
being introduced therein if there is no external force of not less than a predetermined
magnitude.
[0354] Meanwhile, the pouch 2200 may further include a ziplock 2260 to selectively seal
up the upper portion of the the contents-accommodating section 2210. As necessary,
the ziplock 2260 may be omitted.
[0355] The ziplock 2260 includes a female zipper 2261 formed inside the first accommodating
section film 2211 and a male zipper 2263 formed inside of the second accommodating
section film 2213. of course, the positions of the female zipper 2261 and the male
zipper 2263 may be exchanged.
[0356] Also, various well-known sealing means may be employed instead of the ziplock 2260
as long as it can selectively seal up the contents-accommodating section 2210.
[0357] Meanwhile, the pouch 2200 may further include a transparent window 2215, 2216, 2217
for checking whether the contents-accommodating space S6 is sealed up or not. That
is, the defect of the contents-accommodating section 210 can be determined by naked
eyes through the transparent windows 2215, 2216, 2217.
[0358] As shown in FIG. 35, the transparent window 2215 may be arranged between the liquid
reactant entrance 2222 and the upper end of the first accommodating section film 2211.
Through the transparent window 2215, contact between the first accommodating section
film 2211 and the contents accommodated therein is checked by naked eyes, and it is
thus possible to determine whether a product is defective or not. For example, if
solid food is put into the contents-accommodating section 2210 and then the contents-accommodating
space S6 is vacuumized, it is possible to determine by naked eyes through the transparent
window 2215 whether there is a trouble in the vaccumization.
[0359] Meanwhile, the transparent window 216 may be as shown in FIG. 35 and FIG. 36 formed
in a lower portion of the pouch 2200. If the contents accommodated in the contents-accommodating
section 2210 is liquid and the liquid leaks out because the contents-accommodating
section 2210 is defective, it is possible to determine by naked eyes through the transparent
window 2216 of the lower portion whether the product is defective or not. To make
it easier to determine through the transparent window 2216 of the lower portion whether
the contents-accommodating section 2310 is sealed up or not, a corresponding region
of the the first temperature space forming member 2221 formed with the transparent
window 2216 may be transparently formed, but a corresponding region of the first temperature
space forming member 2221 may be opaque. For example, the first temperature space
forming member 2221 may be entirely made of a transparent film, while the first accommodating
section film 2211 may be entirely made of an opaque film.
[0360] Also, the transparent window 2217 formed in a vertical direction may be as shown
in FIG. 35 formed at one side between left and right sides of the pouch 2200 along
a lengthwise direction. Thus, a user leans the pouch 2200 and checks by his/her naked
eyes through the transparent window 2217 whether the contents accommodated in the
contents-accommodating section 2210 leak out or not, thereby determining whether a
product is defective or not.
[0361] The plurality of transparent windows 2215, 2216, 2217 are to check whether the contents-accommodating
space S6 of the contents-accommodating section 2210 is surely isolated from the temperature
control spaces S7, S8. If it is chedcked through the plurality of transparent windows
2215, 2216, 2217 that there is no defect in a product, the contents of the contents-accommodating
space S6 is not affected by a byproduct produced by the exothermic or endothermic
reaction within the temperature control spaces S7, S8.
[0362] The drawings show the plurality of transparent windows 2215, 2216, 2217, but the
number and positions of the transparent windows 2215, 2216, 2217 may be varied.
[0363] Meanwhile, the foregoing description illustrates that the liquid reactant entrance
2222 is formed at only one side between the front and back sides, but not limited
thereto. Alternatively, the liquid reactant entrance 222 may be formed at both the
front and back sides.
<Nineteenth exemplary embodiment>
[0364] The pouch 2200a according to the nineteenth exemplary embodiment as shown in FIG.
38 and FIG. 39 includes the contents-accommodating section 2210; the temperature controller
2220 and a sealing portion 2240.
[0365] The nineteenth exemplary embodiment is the same as the eighteenth exemplary embodiment
except that the ziplock 2260 is omitted and the sealing portion 2240 is arranged in
a different position.
[0366] The sealing portion 2240 of the nineteenth exemplary embodiment may includes an adhesive
tape 2240 attached to the upper end outside of the liquid reactant entrance 2222 and
sealing up the temperature control space S7. Thus, it is possible to prevent foreign
materials (in particular, liquid) from being introduced into the temperature control
spaces S7, S8 while contents are put into the contents-accommodating section S6 and
sterilized after the upper end of the contents-accommodating section S6 is sealed
up.
[0367] Meanwhile, the adhesive tape 2240 includes a tape grip portion 2241 extended so that
its one side can be gripped. Thus, if a user pulls the tape grip portion 2241 and
removes the adhesive tape 2240, the liquid reactant of the liquid reactant container
2190 accommodated in the temperature control space S7 can be easily put into the pouch
2200b.
<Twentieth exemplary embodiment>
[0368] A pouch 2300 according to a twentieth exemplary embodiment as shown in FIG. 40 includes
a contents-accommodating section accommodating section 2110; a temperature controller
2330 provided with a plurality of temperature control agents 2131 respectively arranged
in a first accommodating section film 2112 and a second accommodating section film
2114; a sealing portion 2140 sealing up the plurality of temperature control spaces
2334, 2335 accommodating the plurality of temperature control agents 2131 and the
plurality of liquid reactant container 2190; and a pouch stand 2790 arranged in lower
portions of the first accommodating section film 2112 and the second accommodating
section film 2114 and allowing the pouch 2300 to stand.
[0369] The temperature controller 2330 includes a first temperature control space forming
member 2331, a second temperature control space forming member 2332, a first liquid
reactant insertion portion 2337 and a second liquid reactant insertion portion 2338.
[0370] The first temperature control space forming member 2331 and the second temperature
control space forming member 2332 are respectively opposite to the first accommodating
section film 2112 and the second accommodating section film 2114. Between the first
temperature control space forming member 2331 and the first accommodating section
film 2112 and between the second temperature control space forming member 2332 and
the second accommodating section film 2114 are respectively formed a first temperature
control space 2334 and a second temperature control space 2335. Here, the first temperature
control space 2334 and the second temperature control space 2335 accommodate the temperature
control agent 2131 and the liquid reactant container 2190, respectively.
[0371] Further, the first liquid reactant insertion portion 2337 and the second liquid reactant
insertion portion 2338 are provided in the upper regions of the first temperature
control space forming member 2331 and the second temperature control space forming
member 2332 to open and close the respective temperature control spaces 2334, 2335.
[0372] The sealing portion 340 is provided to seal up the first temperature control space
2334 and the second temperature control space 2335 by the first liquid reactant insertion
portion 2337 and the second liquid reactant insertion portion 2338, respectively.
The sealing portion 340 includes the first sealing portion 2342 for sealing up between
the first accommodating section film 2112 and the first liquid reactant insertion
portion 2337, and the second sealing portion 2344 for sealing up between the second
accommodating section film 2114 and the second liquid reactant insertion portion 2338.
Here, the first sealing portion 2342 and the second sealing portion 2344 may include
the liquid adhesive, the solid adhesive tape or the easy peel film, like the sealing
portion 2140 of the seventeenth exemplary embodiment and
[0373] The grip portion 2350 includes the first grip portion 2352 and the second grip portion
2354 respectively connected to the first liquid reactant insertion portion 2337 and
the second liquid reactant insertion portion 2338 and gripped to open the first temperature
control space 2334 and the second temperature control space 2335. The first grip portion
2352 may be arranged in the center region of the first liquid reactant insertion portion
2337, and the second grip portion 2354 may also be arranged in the center region of
the second liquid reactant insertion portion 2338. The first grip portion 2352 and
the second grip portion 2354 have the same shape as the grip portion 2150 of the seventeenth
exemplary embodiment. of course, the first grip portion 2352 and the second grip portion
2354 may have different shapes from that of the grip portion 2150 of the seventeenth
exemplary embodiment.
[0374] As described above, the pouch 2300 according to the twentieth exemplary embodiment
accommodates two temperature control agents 2131 in two temperature control spaces
2334, 2335 as opposed to the seventeenth exemplary embodiment. Accordingly, the pouch
2300 according to the twentieth exemplary embodiment can more quickly control the
temperature of the temperature controllable object 10 than the pouch 2100 according
to the seventeenth exemplary embodiment.
[0375] Meanwhile, the sealing portion 2140 includes the first sealing portion 2141 for sealing
the first temperature control space 2334, and the second sealing portion 2143 for
sealing the second temperature control space 2335.
[0376] The first and second sealing portions 141, 143 may be made of the same material as
the sealing portion 2140 according to the foregoing seventeenth exemplary embodiment.
[0377] The first and second sealing portions 2141, 2143 seal up between the first temperature
control space forming member 2331 and the first accommodating section film 2112 and
between the second temperature control space forming member 2332 and the second accommodating
section film 2114 so that the first and second liquid reactant entrances 2337, 2338
can be opened when force of not less than a certain magnitude is applied to space
the first and second liquid reactant entrances 2337, 2338 apart from the contents-accommodating
section 2110.
[0378] Here, as shown in FIG. 40, a user may use the first grip portion 2352 and the second
grip portion 2354 to open the first and second temperature control spaces 2334, 2335,
respectively. In the state that the first and second temperature control spaces 2334,
2335 are opened, the liquid reactant container 2190 is taken out and cut, and the
liquid reactant therein is put into the first and second temperature control spaces
2334, 2335. Thus, the exothermic or endothermic reaction occurs in the first and second
temperature control spaces 2334, 2335, thereby heating or cooling the temperature
controllable object within the accommodating space 2116.
<Twenty-first exemplary embodiment>
[0379] A pouch 2300a according to a twenty-first exemplary embodiment as shown in FIG. 41
includes a contents-accommodating section 2110a including the first accommodating
section film 2112, the second accommodating section film 2114 and the spacing film
115 spaced apart from the pouch stand 2790; the temperature controller 230 provided
with the plurality of temperature control agents 2131 respectively arranged in the
first accommodating section film 2112 and the second accommodating section film 2114;
the sealing portion 2140 for sealing up one among the plurality of temperature control
spaces 2234, 2235 accommodating the plurality of temperature control agents 2131;
the grip portion 2150; the sealing-bar attachment-preventing portion 2170, and the
pouch cutting portion (refer to 2180 in FIG. 30).
[0380] The first and second accommodating section films 2112, 114 and the spacing film 115
of the contents-accommodating section 2110a may be all provided a single film. As
necessary, they may be manufactured with individually cut films and then sealed.
[0381] The temperature controller 2230 includes the first and second temperature control
space forming members 2231, 2232 respectively sealed with the first and second accommodating
section films 2112, 114 to form the first and second temperature control spaces 2234,
2234; the plurality of temperature control agents 2131 respectively accommodated in
the first and second temperature control spaces 2231, 2232; and the liquid reactant
container 2190 accommodated in the first temperature control space 2231.
[0382] The first temperature control space forming member 2231 has an upper end arranged
to be lower than the upper end of the contents-accommodating section 2110.
[0383] The first temperature control space forming member 2231 includes the liquid reactant
entrance 2237 through which the liquid reactant exothermically or endothermically
reacting with the temperature control agent 2131 can be inserted in the first temperature
control space 231.
[0384] The sealing portion 2140 is provided between the liquid reactant entrance 2237 and
the first accommodating section film 2112 of the first temperature control space forming
member 2231.
[0385] The liquid reactant entrance 2237, the sealing portion 2140 and the first accommodating
section film 2112 are thermally adhered by heat to be sealed.
[0386] When the upper ends of the first accommodating section film 2112 and the second accommodating
section film 2114 are sealed up by the sealing bar having a predetermined sealing
temperature in order to seal up the upside of the contents-accommodating section 2110,
the first accommodating sectionfilm 2112 may be attached to and not separated from
the sealing bar.
[0387] The sealing-bar attachment-preventing portion 2170 prevents the first accommodating
section film 2112 from being attached to and not separated from the sealing bar.
[0388] In more detail, the first accommodating section film 2112 is as described above made
of a single CPP film or a combination film where the CPP film is exposed. The CPP
film may be sticked to and not well separated from the sealing bar, and to prevent
this, the sealing-bar attachment-preventing portion 2170 may be provided on the first
accommodating section film 2112 contacting the sealing bar.
[0389] The PET substance may be used as a material not well attached to the sealing bar.
The sealing-bar attachment-preventing portion 2170 may include a film of which a part
exposed in a direction of pressing the sealing bar, i.e, frontward is combined with
the PET film, or a single PET film.
[0390] For example, the sealing-bar attachment-preventing portion 2170 may be the same plastic
film as the foregoing temperature control space forming member 2132, where the PET
film having a thickness of 12
µm and the CPP film having a thickness of 60
µm are combined. Here, the PET film has to be arranged to be exposed frontward so that
the PET film can contact the sealing bar.
[0391] Here, it is just illustrative that the PET is used as a material for the sealing-bar
attachment-preventing portion 2170. The PET may be replaced by the plastic films of
various well known materials as long as it cannot well attached to the sealing bar.
[0392] After the temperature controllable object (i.e., the contents) is filled while the
accommodating section 2110a is being opend, the sealing bar heated at a predetermined
temperature applies heat toward the sealing-bar attachment-preventing portion 2170
along the upper edges of the accommodating section 2110, thereby sealing up the upper
end of the accommodating section 2110. Accordingly, it is possible to prevent the
accommodating section 2110 from being attached to the sealing bar.
[0393] The sealing-bar attachment-preventing portion 2170, the first temperature control
space forming member 2231 and the second temperature control space forming member
2232 may be all maded of the same material. For example, each of the sealing-bar attachment-preventing
portion 2170, the first temperature control space forming member 2231 and the second
temperature control space forming member 2232 may be the plastic film where the PET
f ilm having a thickness of 12
µm and the CPP film having a thickness of 60
µm are combined.
[0394] Meanwhile, the pouch cutting portion 2180 may be provided between the liquid reactant
insertion portion 2237 and the sealing-bar attachment-preventing portion 2170.
[0395] The pouch cutting portion 2180 may include a notch in a transverse direction at one
or both sides of the contents-accommodating section 2110 so that

the contents-accommodating section 2110 can be torn when transverse force of not
less than a certain magnitude is applied.
[0396] The cutting portion may be arranged in a relatively thin position so that the pouch
cutting portion (refer to 2180 in FIG. 30) can be easily torn through the notch.
[0397] In more detail, as shown in FIG. 41, the sealing-bar attachment-preventing member
2170 and the liquid reactant insertion portion 2237 may be spaced apart from each
other so that a cutting region A7 where the pouch cutting portion (refer to 2180 in
FIG. 30) with the notch is provided can be relatively thin.
[0398] That is, the cutting region A7 includes only the first accommodating section film
2112 and the second accommodating section film 2114, and it is therefore thinner than
three layered films of the sealing-bar attachment-preventing member 170, the first
and second accommodating section films 2112, 2114 provided at the upper side of the
contents-accommodating section 2110.
[0399] Also, total four films of the temperature control space forming member 2231, the
sealing portion 2140, the first accommodating section film 2112 and the second accommodating
section film 2114 are provided under the cutting region A7, and therefore the cutting
region A7 having two layered films is relatively thin. Thus, the contents-accommodating
section 2110a can be more easily cut by the pouch cutting portion (see 2180 in FIG.
30) formed in the cutting region A7.
[0400] To heat or cool the temperature controllable object, a user grips the grip portion
2150 and applies force to the liquid reactant entrance 2237, thereby opening the first
temperature control space 2234. Further, the liquid reactant container 2190 is taken
out and cut from the open first temperature control space 2234, and the liquid reactant
is inserted in the opened first temperature control space 2234. The liquid reactant
put into the first temperature control space 2234 is introduced into a second temperature
control space 235 through a communication space H1 between the liquid reactant

the accommodating section 2110 and the pouch stand 2790. Thus, the exothermic or
endothermic reaction can occur between the liquid reactant and the temperature control
agent 2131 within even the second temperature control space 2235.
[0401] In the case of the pouch 300b according to the twenty-first exemplary embodiment,
even though a user opens not both the temperature control spaces 2234, 2235 but one
of them to insert the liquid reactant, the inserted liquid reactant can be transferred
to the unopened space. Accordingly, it is convenient for a user.
[0402] Meanwhile, the sealing-bar attachment-preventing portion 2170 and the pouch cutting
portion 2180 described above are not essential, and all or a part of the foregoing
elements 2170, 2180 may be omitted.
<Twenty-second exemplary embodiment>
[0403] The pouch 2100b according to the sixth exemplary embodiment as shown in FIG. 42 includes
the contents-accommodating section 2110, the temperature controller 2130, the sealing
portion 2240, the grip portion 2150, the sealing-bar attachment-preventing portion
2170 and the cutting portion (see 2180 in FIG. 30).
[0404] The pouch 2100b according to the twenty-second exemplary embodiment is different
from the pouch 2100 of the seventeenth exemplary embodiment in the shape of the sealing
portion 2140 according to the seventeenth exemplary embodiment.
[0405] The sealing portion 2240 may be provided to conver the entire of the first accommodating
section film 2112 of the contents-accommodating section 2110.
[0406] In the case of the pouch 2100 according to the seventeenth exemplary embodiment,
the sealing portion 2140 has a predetermined width as shown in FIG. 31. On the other
hand, the sealing portion 2240 according to the eighth exemplary embodiment is provided
to cover the entire front side of the contents-accommodating section 2110.
[0407] Here, the sealing portion 2240 may include at least one among the liquid or solid
adhesive tape for adhesion between the first accommodating section film 2112 and the
liquid reactant insertion portion 2136, and the easy peel film arranged between the
first accommodating section film 2112 and the liquid reactant insertion portion 2136.
[0408] Here, the solid adhesive tape may be a film type tape, one or both sides of which
the adhesive is applied to.
[0409] The easy peel film couples both films thereof with predetermine thermal adhesion
when heat of a predetermined temperature range is applied. Here, the coupling force
or adhesion may be controlled by adjusting the temperature range of heat applied to
the easy peel film.
[0410] In the case of the twenty-second exemplary embodiment, the sealing portion 2240 is
provided to cover the entire of the first accommodating section film 2112, and therefore
there is no need of position control work for positioning the sealing portion 2240
to a certain position between the liquid reactant entrance 2136 and the first accommodating
section film 2112. For reference, in the case of the sealing portion 2140 according
to the seventeenth exemplary embodiment shown in FIG. 31, it is positioned at only
a specific potion, and therefore there is a need of work for positioning the sealing
portion 2140 to the corresponding position.
<Twenty-third exemplary embodiment>
[0411] A pouch 1000 according to a twenty-third exemplary embodiment as shown in FIG. 43
and FIG. 44 includes a contents-accommodating section 1100 for accommodating contents,
and a temperature controller 1200 provided with temperature control agent 1210 and
the liquid reactant insertion portions 1230, 1240.
[0412] The contents CA1 may include retort pouch such as solid boiled rice, Bibimbap, liquid
soup, stew or dry milk; a pad containing medicine for taking a hot massage or a cold
massage, or a mask pad containing beauty ingredients. Besides, the contents may be
variously selected as long as it has to be instantly heated or cooled. Besides the
foregoing retort pouch, the food needed for sterilization for prolong expiration date
may also be included in the contents CA1 regardless of the kind or types.
[0413] The contents-accommodating section 1100 may form a contents-accommodating space SP1
where the contents CA1 are accommodated.
[0414] The contents-accommodating section 1100 includes the first accommodating section
film 1110 and the second accommodating section film 1120.
[0415] The first accommodating section film 112 and the second accommodating section film
114 may be made of the plastic film.
[0416] In more detail, the first accommodating section film 1110 and the second accommodating
section film 1120 may be made of the plastic film such as polyethylene (PE), polypropylene
(PP), or a polyethyelene terephthalate (PET). Of course, the first accommodating section
film 112 and the second accommodating section film 114 constituting the accommodating
section 110 may be made of well-known synthetic resin films of various materials.
[0417] For example, the first accommodating section film 1110 may include a CPP film having
a thickness of 60
µm, an aluminum film having a thickness of 9
µm, or a combination film between a nylon film having a thickness of 15
µm and a CPP film having a thickness of 60
µm. Of course, this is nothing but illustrative. The first accommodating section film
1110 may include a combination film of various materials, or as necessary include
a film of a single material. The second accommodating section film 1120 may be made
of the same material as that of the first accommodating section film 1110. As necessary,
the second accommodating section film 1120 may be made of different materials from
the first accommodating section film 1110.
[0418] The left, right and lower ends SA2, SA3, SA4 of the first accommodating section film
1110 and the second accommodating section film 1120 are sealed up to form the contents-accommodating
space SP1.
[0419] The upper end of the contents-accommodating space SP1 may be opened to put the contents
CA1 therein. After the contents CA1 is put in the contents-accommodating space SP1,
the upper end of the contents-accommodating space SP1 may be sealed. A sealing method
may includes a method of using the sealing bar to fuse two films 1110, 1120 with heat,
or a method of fusing two films 1110, 1120 with ultrasonic waves or microwaves. Besides,
if the contents are not food, two films 1110, 1120 may be sealed up by adhesive or
an adhesive film. Besides the foregoing sealing methods, well-known various sealing
methods may be employed.
[0420] As necessary, if the contents CA1 are solid food or a pad for beauty or treatment,
the upper end of the contents-accommodating space SP1 may not be sealed. Also, in
the case that food to be heated or cooled is put into the contents-accommodating space
SP1 of the pouch 1000 and then directly the liquid reactant is inserted in the temperature
control space SP2 formed by the temperature controller 1200, the upper end of the
contents-accommodating space SP1 may not be sealed.
[0421] As shown in FIG. 44, the temperature controller 1200 is arranged in a front side
of the contents-accommodating section 1100 and forms the temperature control space
SP2. Of course, as necessary, the temperature controllers 1200 may be arranged in
the back side as well as the front side, and thus form the temperature control space
at opposite sides with the contents-accommodating section 1100 therebetween.
[0422] The temperature controller 1200 includes the temperature control agent 1210 to be
accommodated in the temperature control space SP2; and the temperature control space
forming member 1220 forming the temperature control space SP2 where the exothermic
or endothermic reaction occurs.
[0423] The temperature control agent 1210 reacts with the liquid reactant (refer to W2 in
FIG. 45) put into the temperature control space SP2, thereby causing the exothermic
or endothermic reaction. Here, The temperature control agent 1210 may include the
liquid reactant (refer to W2 in FIG. 45).
[0424] The temperature control agent 1210 includes the reactant 1211 exothermically or endothermically
reacting with the liquid reactant (refer to W2 in FIG. 45) and the reactant accommodating
section 1213. The reactant 1211 includes the heating element or the heat absorption
agent causing the exothermic or endothermic reaction.
[0425] The reactant 1211 may include at least one as the heating element among calcium oxide
(CaO), calcium hydroxide (Ca(OH)
2), magnesium chloride (MgCl
2), iron (Fe) and aluminum (Al). Here, the reactant 1211 may be replaced by varioius
materials as long as it can exothermically react with the liquid reactant W2.
[0426] Meanwhile, the reactant 1211 may include at least one as the heat absorption agent
among ammonium nitrate (NH4NO3), sodium acetate (CH3COONa) and (urea). Of course,
the reactant 1211 may be replaced or changed by other substances as long as it can
endothermally react with the liquid reactant W2.
[0427] The reactant accommodating section 1213 accommodates the reactant 1211. The reactant
accommodating section 1213 may be provided as an absorption fabric to absorb or transmit
the liquid reactant W2. As necessary, the reactant accommodating section 1213 may
be made of various materials that can absorb or transmit the liquid reactant W2.
[0428] The temperature control space forming member 1220 is opposite to the first accommodating
section film 1110 of the contents-accommodating section 1100 and forms the temperature
control space 134 for accommodating the temperature control agent 1210 therebetween.
[0429] The temperature control space forming member 1220 may be made of a transparent synthetic
resin film so that the liquid reactant W2 and the temperature control agent 1210 to
be inserted can be checked by naked eyes. Of course, the temperature control space
forming member 1220 may be partially made of the transparent synthetic resin film
checkable by naked eyes. Of course, checkability by naked eyes is optional, and thus
an opaque film may be used as necessary.
[0430] The upper end sealing regions SA1 of the temperature control space forming member
1220 and the first accommodating section film 1110 may be aligned with each other
and then sealed up as shown in FIG. 44. As necessary, the upper end of the temperature
control space forming member 1220 may be positioned lower than the upper end of the
first accommodating section film 1110m abd tge yooer end of the temperature control
space forming member 1220 may be coupoled to the first accommodating section film
1110.
[0431] The temperature control space forming member 1220 maybe provided as the plastic film
such as PP, PE, PET, etc. For example, the temperature control space forming member
1220 may include the plastic film where the PET film having a thickness of 12
µm and the CPP film having a thickness of 60
µm are combined. Of course, this is nothing but illustrative. Alternatively, the plastic
film may be a combination film where films of various well-known substances are combined
or a single material film.
[0432] Meanwhile, the temperature control space forming member 1220 is arranged to be lower
than the upper end of the contents-accommodating section 1110, and includes the liquid
reactant insertion portions 1230, 1240 into which the liquid reactant (refer to W2
in FIG. 45) can be put.
[0433] The liquid reactant insertion portions 1230, 1240 includes a first folding portion
1230 where the temperature control space forming member 1220 is folded outwrd; and
a first cutting portion 1240 for cutting the first folding portion 1230.
[0434] Here, the first folding portion 1230 may be folded inward as opposed to that shown
in FIG. 44. In this case, the first folding portion 1230 may be partially exposed
to the outside so that a user can take out the inward folded first folding portion
1230 before cutting the first folding portion 1230.
[0435] The first folding portion 1230 may protrude to have an end being gradually inclined
downward as shown in FIG. 44. Thus, it is possible to prevent the liquid reactant
remaining after the reaction from leaking out through the cut first folding portion
1230.
[0436] The first cutting portion 1240 may include notches respectively arranged at opposite
edges of the first folding portion 1230. As necessary, the notch may be formed at
only one side.
[0437] The first cutting portion 1240 may include a cutting groove (not shown) extended
along a cutting direction instead of the shown notch. To prevent foreign materials
from being introduced into the temperature control space SP2 through the cutting groove
(not shown), the cutting groove (not shown) may be not a slit completely penetrating
the temperature control space forming member 1220 but a groove where the temperature
control space forming member 1220 is relatively thin.
[0438] Meanwhile, the temperature control space forming member 1220 may further include
a second folding portion 1250 to be expanded by vapor generated by the exothermic
reaction in the temperature control space SP2. Here, the second folding portion 1250
may be omitted as necessary.
[0439] Below, use of the pouch 1000 according to the foregoing twenty-third exemplary embodiment
will be described with reference to FIG. 45 to FIG. 47.
[0440] As described above, the contents CA1 may be put in by a manufacturer or may be put
in the opened contents-accommodating section 1100 of the pouch 1000 by a user. In
the state that the contents CA1 to be controlled with regard to temperature are accommodated
in the contents-accommodating section 1100, a user cuts the first folding portion
1230 through the first cutting portion 1240.
[0441] Thus, as shown in FIG. 45, the first folding portion 1230 is divided into a first
upper folding part 1231 and a first lower folding part 1233. Thus, the temperature
control space SP1 is opened. The liquid reactant W2 is put in between divided first
upper and lower folding parts 1231, 1233.
[0442] As shown in FIG. 46, the put liquid reactant exothermically or endothermically reacts
with the temperature control agent 1210. Here, if the exothermic rection occurs, vapor
is generated and the generated vapor is discharged to the outside through the divided
first upper and first lower folding parts 1231, 1233 while expanding the second folding
portion 1250.
[0443] Here, even though an abnormal state that vapor is suddenly and explosively generated
happerns during the exothermic process, it can be damped as the second folding portion
1250 expands. Thus, it is possible to prevent the temperature control space forming
member 1220 from being torn as it cannot stand vapor pressure, and prevent the temperature
control space SP2 from being opened in other sealing portion except the liquid reactant
insertion portions 1230, 1240 and the liquid reactant W2 from flowing out.
[0444] As necessary, a user may transfer the heated or cooled contents CA1 by the exothermic
or endothermic reaction to a separate external container A9 in order to take it in.
In this case, as shown in FIG. 47, the liquid reactant W3 remaining in the temperature
control space SP2 after the reaction is blocked by the upper end sealing regions SA1
of the temperature control space forming member 1220 and the first accommodating section
film 1110 and does not leak out. As described above, the first folding portions 1231,
1233 protrude being inclined downward, and thus the first folding portions 1231, 1233
are inclined upward when the pouch 1000 is turned upside down as shown in FIG. 47,
thereby further preventing the liquid reactant W3 from leaking out.
[0445] Here, the upper end sealing regions SA1 of the temperature control space forming
member 1220 and the first accommodating section film 1110 are used as a liquid reactant
leaking-out preventing portion.
[0446] Meanwhile, the foregoing is described under conditions that the liquid reactant is
not accommodated in the pouch 1000, but not limited thereto. As necessary, the liquid
reactant may be accommodated and sealed in the temperature control space SP2 of the
pouch 1000.
[0447] In more detail, as shown in FIG. 48, the liquid reactant portion 1300 including the
liquid reactant W2; and a liquid reactant bag 1310 for packing the liquid reactant
W2 may be provided inside the temperature control space SP2.
[0448] The liquid reactant bag 1310 may include an accommodating space portion 1313 for
forming the accommodating space to accommodate the liquid reactant W2; a liquid reactant
discharging portion 1311 through which the accommodated liquid reactant W2 can be
discharged; and a cut portion 1314 for cutting the upper end of the liquid reactant
discharging portion 1311. The liquid reactant discharging portion 1311 may be narrower
than the accommodating space portion 1313. Thus, the liquid reactant can be easily
discharged toward a predetermined target.
[0449] The amount of liquid reactant for optimally racting with the temperature control
agent 1210 is defined. If a general user is allowed to put the liquid reactant into
the temperature control space SP2, the exothermic or endothermic reaction may not
occur as originally designed since a random amount of liquid reactant is put.
[0450] Thus, as necessary, the liquid reactant portion 1300 containing the optimal amount
of liquid reactant for reacting with the temperature control agent 1210 provided in
the temperature control space SP2 may be internally provided.
[0451] The liquid reactant portion 1300 together with the temperature control agent 1210
may be placed in the temperature control space SP2. At this time, the temperature
control space SP2 may be sealed up in the state that the liquid reactant portion 1300
and the temperature control agent 1210 are both placed.
[0452] The liquid reactant portion 1300 is not open if a user artificially cuts the cut
portion 1314, and therefore the liquid reactant does not leak out from the liquid
reactant bag 1310.
[0453] A method of using the pouch provided with both the liquid reactant portion 1300 and
the temperature control agent 1210 is as follows. Using the first cutting portion
1240 shown in FIG. 43, the first folding portion 1230 is cut to open the temperature
control space SP2.
[0454] From the open temperature control space SP2, the liquid reactant bag 1310 is taken
out and its cut portion 1314 is cut. Then, the liquid reactant W2 contained in the
liquid reactant bag 1310 is put into the temperature control space SP2.
[0455] Thus, the exothermic or endothermic reaction occurs in the temperature control space
SP2 so that the contents CA1 filled in the contents-accommodating section 1110 can
be heated or cooled.
[0456] Except for taking out and putting the liquid reactant portion 1300 containing the
liquid reactant, the other using methods are the same as the foregoing pouch using
method, and thus repetitive descriptios will be avoided.
[0457] Meanwhile, the foregoing illustrates that the liquid reactant portion 1300 is accommodated
in the temperature control space SP2, but not limited thereto. As necessary, the liquid
reactant portion 1300 may be detachably attached to the pouch 1000 by adhesive or
the like on the outer surface. Besides, the liquid reactant portion 1300 may be couled
to the pouch 1000 in various forms as long as it can together with the pouch 1000
be carried.
<Twenty-fourth exemplary embodiment>
[0458] A pouch 1000a according to the twenty-fourth exemplary embodiment as shown in FIG.
49 and FIG. 50 includes a contents-accommodating section 1100a; a temperature controller
1200a; a liquid reactant portion 1300; and a pouch stand 1400.
[0459] The pouch 1000a according to the twenty-fourth exemplary embodiment is different
from that of the foregoing twenty-third exemplary embodiment in that the contents-accommodating
section 1100a is formed as a single body, in that the temperature control space SP3,
SP4 and the temperature control agent 1210 are arranged at both front and back sides
with the contents-accommodating section 1100a therebetween, and in that the pouch
1000a can stand by itself. Here, the liquid reactant portion 1300 may be not accommodated
in the pouch 1000a as described above.
[0460] The contents-accommodating section 1100a includes a first accommodating section film
2110a and a second accommodating section film 1120a. The first and second accommodating
section films 1110a, 1120a may be formed as a single body. That is, the contents-accommodating
section 1100a may be provided in the form of foling one sheet of film so as to form
the contents-accommodating space SP1. The contents-accommodating section 1100a according
to the twenty-third exemplary embodiment is formed by thermally sealing up two films
of the first accommodating section film 1110 and the second accommodating section
film 1120. On the other hand, the contents-accommodating section 1100a according to
the twenty-fourth exemplary embodiment is formed as a single body.
[0461] The lower end 1130 of the contents-accommodating section 1100a is spaced apart from
a standing portion 1400. Thus, the liquid reactant to be put into the temperature
controller 1200a can flow out from the first temperature control space SP3 to the
second temperature control space SP4 through the communication space SP5 between the
lower end 1130 of the contents-accommodating section 1100a and the standing portion
1400.
[0462] The temperature controller 1200a according to the twenty-fourth exemplary embodiment
includes a first temperature control space forming member 1220 opposite to the first
accommodating section film 1110 of the contents-accommodating section 1100 and forming
the first temperature control space SP3; a second temperature control space forming
member 1260 opposite to the second accommodating section film 1120 of the contents-accommodating
section 1100; a plurality of temperature control agents 1210 respectively arranged
in the first and second temperature control spaces SP3, SP4; the liquid reactant insertion
portions 1230, 1240 formed in the first temperature control space forming member 1220;
and the second folding portion 1250.
[0463] As described above, the liquid reactant insertion portion 1230 includes a plurality
of first folding portion 1230; and a first cutting portion (refer to 1240 in FIG.
43) for respectively utting the plurality of first folding portion 1230. Here, when
the plurality of first folding portions 1230 are respectively cut and the liquid reactant
cause the exothermic reaction, generated reaction gas may discharge cold air from
the first and second temperature control space to the outside through the plurality
of first folding portions 1231, 1233 cut at opposite sides. Thus, the contents CA1
can be quickly heated and thermal efficiency can be improved.
[0464] The plurality of first folding portion 1230 may protrude from the first temperature
control space forming member 1220 and the second temperature control space forming
member 1260, respectively.
[0465] As necessary, the plurality of first folding portion 1230 may be provided in only
one of the first temperature control space forming member 1220 and the second temperature
control space forming member 1260.
[0466] The plurality of first folding portion 1230 may have a protruding end being inclined
down.
[0467] Here, as described above, the second folding portion 1250 may be omitted as necessary.
[0468] The pouch 1000a according to the twenty-fourth exemplary embodiment as shown in FIG.
43 and FIG. 44 further includes an upper end sealing portion SA1 for sealing up the
upper end portion of the contents-accommodating section 1100a; a liquid reactant leak-out
preventing portion SA5 placed between the upper end sealing portion SA1 and the first
folding portion 1230 and preventing the put liquid reactant from leaking outward from
the temperature control space SP3; and a second cutting portion 1010 placed between
the upper end sealing portion SA1 and the liquid reactant leak-out preventing portion
SA5 and cutting the upper end sealing portion SA1 from the contents-accommodating
section 1100a to open the contents-accommodating section 1100a.
[0469] The upper end sealing portion SA1 may be as shown in FIG. 44 sealed up with the upper
end portions of the first and second temperature control space forming members 1210,
1260 as well as the contents-accommodating section 110.
[0470] As necessary, the upper ends of the first and second temperature control space forming
members 1210, 1260 may be placed to be lower than the upper end of the contents-accommodating
section 1100a. The upper ends of the first and second temperature control space forming
members 1210, 1260 may be regarded as the upper end of the liquid reactant leak-out
preventing portion SA5.
[0471] The liquid reactant leak-out preventing portion SA5 includes the sealing portion
SA5 for sealing up between the contents-accommodating section 1100a and the first
temperature control space forming member 1220 along a transverse direction at a position
spaced apart from the first folding portion 1230 in a longitudinal direction in order
to prevent the liquid reactant from leaking out.
[0472] The contents-accommodating section 1100a, the first and second temperature control
space forming members 1210, 1260 are coupoled by sealing up the respective left and
right ends SA2, SA3 thereof.
[0473] The standing portion 1400 is arranged between the first and second temperature control
space forming members 1210, 1260 so that the lower end portions of the first and second
temperature control space forming members 1210, 1260 can be spaced apart from each
other. Thus, it forms a lower region closed curve of the pouch 1000a according to
the twenty-fourth exemplary embodiment, so that the pouch 1000a can stand by itself
without any separate device.
[0474] In more detail, the standing portion 1400 includes a first end SA4 sealing-coupled
to the first temperature control space forming member 1210, and a second end SA6 sealing-coupled
to the second temperature control space forming member 1260.
[0475] The process of using the pouch 1000a according to the foregoing twenty-fourth exemplary
embodiment will be described with reference to FIG. 51. Using the first cutting portion
1240, the first folding portion 1230 is cut.
[0476] Through the cut first folding portions 1231, 1233, the liquid reactant portion 1300
is taken out from the first temperature control space SP3.
[0477] The cut portion (refer to 1314 in FIG. 48) of the taken-out liquid reactant portion
1300 is cut. Further, the liquid reactant bag 1310 is squeezed to inject the liquid
reactant W2 into the first temperature control space SP3 through the cut first folding
portions 1231, 1233.
[0478] The injected liquid reactant W2 causes the exothermic or endothermic reaction in
the first temperature control space SP3. Meanwhile, the unreaded and remaining liquid
reactant W2 is discharged to the second temperature control space SP4 through the
communication space SP5. The discharged liquid reactant exothermically or endothermically
reacts again with the temperature control agent 1210 provided in the second temperature
control space SP4.
[0479] Thus, the contents CA1 accommodated inthe contents-accommodating section 1100a can
be heated or cooled.
[0480] To take out or take in the heated or cooled contents CA1, the second cutting portion
(refer to 1010 in FIG. 49) is cut to open the contents-accommodating section 1100a.
[0481] At this time, if the pouch 1000a is turned upside down in order to transfer the contents
CA1 accommodated in the contents-accommodating section 1100a to a separate external
container (refer to A in FIG. 47), the liquid reactant W3 remaining in the first temperature
control space SP3 after the reaction is blocked by the liquid reactant leak-out preventing
portion SA5 and prevented from leaking out.
[0482] Although a few exemplary embodiments have been shown and described, it will be appreciated
by those skilled in the art that changes may be made in these exemplary embodiments
without departing from the principles and spirit of the invention, the scope of which
is defined in the appended claims and their equivalents.
