TECHNICAL FIELD:
[0001] The present invention relates to a cling wrap case with a form where a cling wrap
film stored within a case can be used by pulling out and cutting off to a required
length as required.
BACKGROUND TECHNOLOGY:
[0002] Since this type of cling wrap case that has been conventionally known has construction
in which a metal cutter is attached to a cardboard box (refer to Patent Reference
1, the cutter and the cardboard box are thrown away after separating them from each
other, which is also troublesome (reference is made, for example, to Japanese Utility
Model Publication Hei 07 - 38129).
[0003] Further, the disposable cling wrap case is not preferable for restraining environmental
pollution, highlighted as a problem in recent years; for lessening the waste of earth's
resources and incineration fuel; and for diminishing the waste collecting cost of
each household and local government.
[0004] At present, while the environmental problems have been questioned, vinyl chloride
has become a general social problem because of the generation of dioxin, so cling
wrap made from vinyl chloride is about to be changed to a polyethylene cling wrap.
[0005] However, in the case of trying to cut off the polyethylene cling wrap by a conventional
cardboard box case cutter, since the polyethylene cling wrap is sticky compared vinyl
chloride cling wrap, it is difficult to cut it off, and in the case of forcibly cutting
it off, there is a possibility that it may inadvertently cause hand cuts.
[0006] Further, when the polyethylene cling wrap is cut off, since the hand is generally
rotated and turned toward the user, an end portion of the cut cling wrap film often
clings together, so there are many cases in which users cannot smoothly use the cut
cling wrap film.
[0007] Further, with conventional cling wrap, in the case of pulling out or cutting off
the cling wrap film, there is also the problem that fingers touch the cutter, which
may easily cause finger cuts.
[0008] The objective of the present invention is to resolve the various problems in the
background technology. Specifically, the objective is to provide a new cling wrap
case that is easily, assuredly and safely used, even for polyethylene cling wrap that
is not disposable but which is repeatedly usable for many times; enabling savings
of resources.

as shown in Fig. 2 and Fig. 4, a fastener means 25 is magnetically established at
the back surface side of the bottom of the storage case 2. Further, the cling wrap
film 5 is formed from polyethylene, or polypropylene, or a composite material of polyethylene
and polypropylene. Further, the cutter member 34 is toothed.
[0070] Illustrated embodiments of the present invention arc explained next.
[0071] First, the cling wrap case 1 relating to the present invention, as shown in Fig.
1 and Fig. 2, is constructed by establishing the storage case 2 and the cover 3, and
both the storage case 2 and cover 3 are molded from a synthetic resin, specifically,
from the ABS resin.
[0072] The storage case 2, as shown in Fig. 1 and Fig. 2, stores the cylindrically-formed
cling wrap roll 4 and holds it. Concurrently, it is formed to be horizontally long
box-like whose upper portion is opened, so as to be able to pull out the cling wrap
film 5.
[0073] Furthermore, the cling wrap roll 4, as shown in Fig. 2 and Fig. 4, is constructed
by wrapping the cling wrap film 5 around the external circumference of the tube 6,
formed to be cylindrical from cardboard. Then, the cling wrap film 5 is formed from
polyethylene, or polypropylene or a composite material of polyethylene and polypropylene.
The conventional vinyl chloride cling wrap film generates a toxic substance, such
as dioxin, in the case of incineration. However, this cling wrap film 5, formed from
polyethylene generally, does not generate any toxic substance even when it is incinerated,
preventing environmental pollution.
[0074] The cling wrap roll 4 that is stored within the storage case 2, as shown in Fig.
1, Fig. 5 and Fig. 6, is held by seizing with cling wrap seizing members 7 so as not
to slip out. The cling wrap seizing members 7 are attached to the end walls 8, formed
at both lengthwise ends of the storage case 2.
[0075] The cling wrap seizing members 7, as shown in Fig. 1, Fig. 5 and Fig. 6, have disc-state
heads 9 and cylinders 10, which project inward from the heads 9, respectively, the
cylinders 10 being formed so as to be easily elastically deformed, and seizing parts
12 are established on the external surfaces of the end of the cylinders 10, respectively.
[0076] In the cling wrap seizing members 7, as shown in Fig. 1, Fig. 5 and Fig. 6, the heads
9 are arranged at the external surface sides of the end walls 8, formed at both lengthwise
ends of the storage case 2, and the cylinders 10 are fitted in a state which penetrates
through holes 13, formed in the end walls 8, respectively.
[0077] Construction is such that the cylinders 10 of the cling wrap seizing member 7 are
movable inward and outward relative to the holes 13, respectively. When these are
moved outward, the seizing parts 12 seize at the edge of the holes 13 at the internal
surface sides of the end walls 8, preventing the cylinders 10 from slipping out, and
if the cylinders 10 are reduced toward the radical direction, the seizure by the seizing
parts 12 is disengaged, and the seizing parts 12 become passable through the holes
13, and the cling wrap seizing members 7 become removable from the end walls 8, respectively.
[0078] When the cling wrap roll 4 is stored within the storage case 2; the cling wrap seizing
members 7 are fitted to the end walls 8, respectively; and when the cylinders 10 are
moved inward, the cylinders 10 are inserted into the inside of the tube 6 of the cling
wrap roll 4, and the cling wrap roll 4 is held so as not to be released from the storage
case 2.
[0079] Conversely, if the cylinders 10 are extracted from the end walls 8, the cling wrap
roll 4 becomes free and extractable from the storage case 2. Furthermore, the dimension
has been established so as to be able to extract the cling wrap roll 4 even if the
cylinders 10 are moved outward and these become in the state where the seizing parts
12 are still seized at the edges of the holes 13 at the internal surface side of the
end walls 8, respectively.
[0080] In the case of pulling out the cling wrap film 5 of the cling wrap roll 4, which
is stored within the storage case 2, the cling wrap roll 4 turns. Therefore, if the
cling wrap roll 4 does not smoothly turn, it obstructs the pulling-out of the cling
wrap film 5. Then, the ribs 14 for the purpose of easily tuming the cling wrap roll
4 are formed widthwise at multiple lengthwise places on the bottom surface of the
storage case 2.
[0081] The ribs 14 have the cling wrap abrading surfaces 15, which can support the cylinder
cling wrap roll 4 to allow to the roll to be turnable and are formed from a curved
surface, respectively.
[0082] Furthermore, the ribs 14 can be formed such that the height dimension of the widthwise
rear side of the storage case 2 shall be greater than that of the widthwise front
side. In this case, the cling wrap roll 4 arc arranged in a state where they always
protrude forward due to the difference of the height of the ribs within the storage
case 2, so any rewind will never occur backward along the widthwise direction of the
storage case 2, and the pulling-out of the cling wrap film 5 becomes easier for next
use.
[0083] As shown in Fig. 1 and Fig. 2, a jaw plate 17, which protrudes forward, is established
at the widthwise front end of the storage case 2, in other words, at the upper end
of the from wall 16 in the storage case 2, and the cutter member housing 18 is established
on the jaw plate 17.
[0084] The cutter member housing 18, as shown in Fig. 1 and Fig. 2, is comprised of a pair
of the front & rear cutter member housing walls 19 & 20 that are vertically arranged
in parallel. These cutter member housing walls 19 & 20 are formed along the lengthwise
direction at the upper surface side of the jaw plate 17, and the notches 21 & 22 with
a width where fingers can be inserted, as shown in Fig. 1 and Fig. 2, are formed in
the lengthwise center, respectively.
[0085] Therefore, the insertion of fingers into the notches 21 & 22 enables easy pulling-out
of the cling wrap film 5 of the cling wrap roll 4, which is stored within the storage
case 2, by grasping with fingers.
[0086] The cling wrap slip stoppers 23, as shown in Fig. I and Fig. 2, are established on
the upper surface, the front side and the rear side of the cutter member housing wall
20, which is positioned behind widthwise in the cutter member housing 18.
[0087] The cling wrap slip stoppers 23 are formed by adhering a sheet-state material, in
the present embodiments. The cling wrap slip stoppers 23 that are formed to be sheet-state
have a structure where an elastic ABS resin, which demonstrates an extremely high
non-slip property even with a minute load, is laminated onto a synthetic rubber padding
containing a carbon ceramic.
[0088] Furthermore, the cling wrap slip stoppers 23 can also be established by applying
an adhesive capacity substance.
[0089] Further, a plastic plate containing a powder magnet 26, as shown in Fig. 2 and Fig.
4, is adhered onto the back surface side of the bottom plate 24 of the storage case
2 as the fastener means 25 utilizing a magnetic force. Therefore, in the case of not
using this cling wrap case 1, it can be stored by adhering onto a refrigerator, generally.
[0090] Further, the cover 3, as shown in Fig. 1 through Fig. 4, is formed to be horizontally
long box-state so as to be able to cover the upper portion of the storage case 2,
and its widthwise rear end is rotatably connected to the widthwise rear end of the
storage case 2. In other words, hinges 29 & 30 are formed at the upper end of the
rear wall 27 in the storage case 2, and at the lower end of the rear wall 28 of the
cover 3 along the lengthwise direction, respectively, and the insertion of a central
rotation axis 31 into these hinges 29 & 30 results in the rotatable connection of
the cover 3 and the storage case 2.
[0091] In other words, it is constructed such that rotating of the cover 3 forward, as shown
in Fig. 3 and Fig. 4, results in covering &
closing the upper portion of the storage case 2. Conversely, rotating backward results in
opening the upper portion of the storage case 2.
[0092] The stoppers 32 & 33, which can stop the rotating at approximately 135 ° from the
close state, are established, as shown in Fig. 8 and Fig. 9, at the positions where the
cover 3 and the storage case 2 are rotatably connected, so as not to fully open the
cover 3 relative to the storage case 2. Furthermore, the configuration and the structure
of these stoppers 32 & 33 are various, and are not be limited to that which is illustrated.
[0093] Further, as shown in Fig. 1 through Fig. 4, the cutter member 34 is established at
the end of the cover 3 along the rotating direction, in other words, at the widthwise
front end. This cutter member 34 is formed by establishing a serration 36 along the
one side edge of a narrow metal plate 35, and the serration 36 is toothed.
[0094] The cutter member 34, as shown in Fig. 1, is arranged lengthwise, slightly behind
the front wall 37 in the cover 3, and its anchor extremity is fixed to the cover 3.
[0095] As shown in Fig. 3 and Fig. 4, when the cover 3 is rotated forward and it covers
&
closes over the storage case 2, the cutter member 34 is arranged so as to be inserted into
the cutter member housing 18 from the upper portion, and so as to be positioned between
a pair of the cutter member housing walls 19 & 20.
[0096] The back board 38 is established in the lengthwise direction of the cutter member
34, as shown in Fig. 1 through Fig. 4, at the front end of the cover 3 and slightly
behind the cutter member 34.
[0097] The end of the back board 38 is formed so as to be protruded outward more than the
cutting edge of the cutter member 34. Further, the end of the front wall 37 in the
cover 3 is also formed so as to be protruded outward more than the cutting edge of
the cutter member 34. In other words, the cutting edge of the cutter member 34 is
formed to be lower than the end of the back board 38 and the end of the front wall
37.
[0098] Therefore, in the case that a finger is brought close to the cutting edge of the
cutter member 34 while the cover 3 is opened, the finger makes contact with the end
of the back board 38 or the end of the front wall 37, and any contact of the cutting
edge of the cutter member 34 by the finger can be prevented. This enables the prevention
of finger cuts by touching the cutting edge, and the safety can be enhanced.
[0099] Further, the back board 38, as shown in Fig. 4, has a function to push down the cling
wrap film 5, placed on the cutter member housing walls 19 & 20, from top to bottom
behind the rear side of the cutter member housing wall 20 when the cover 3 is rotated
forward and covers &
closes over the storage case 2, enabling the application of a tension force to the cling
wrap film 5.
[0100] As shown in Fig. 1 and Fig. 7, the lock mechanisms 39, for the purpose of securing
the state where the cover 3 is rotated forward and it covers &
closes over the storage case 2, are established.
[0101] The lock mechanisms, as shown in Fig. 1 and Fig. 7, are comprised of lock pieces
40 and seizing grooves 41, respectively. For the lock pieces 40, their ends are established
so as to protrude from the end walls 42, which are at both lengthwise ends of the
cover 3, respectively, and the seizing grooves 41 are formed on the internal surfaces
of the end walls 8, which are at both lengthwise ends of the storage case 2, respectively.
[0102] While the cover 3 is rotated forward and covers &
closes over the storage case 2, it is constructed such that the engagements of end hooks
43 of the lock pieces 40 with the seizing grooves 41 result in the locked state, respectively.
[0103] A knob 44 is established at the widthwise front end on the external surface of the
cover 3, as shown in Fig. 3, for the purpose of easily opening the cover 3 by grasping
with fingers.
[0104] The cling wrap case 1 relating to the present invention is used as follows:
[0105] As shown in Fig. 1 and Fig. 2, the cover 3 is rotated backward and it results in
the opening of the upper portion of the storage case 2, and while the cling wrap seizing
members 7 are extracted from the end walls 8 of the storage case 2, respectively,
or the cling wrap seizing members 7 are moved outward, the cylindrical cling wrap
roll 4 is stored inside the empty storage case 2.
[0106] In this case, while the cover 3 is opened, the cover 3 is secured so as not to be
fully opened by the stoppers 32 & 33, so even a user with small hands can easily hold
the cling wrap case 1, and it is also easily operable.
[0107] Further, as mentioned above, while the cover 3 is opened, when a hand is brought
close to the cutter member 34, which is attached to the cover 3, the hand touches
the end of the back board 38 or the end of the front wall 37, so touching the cutter
member 34 by hand is prevented. Therefore, it prevents hurting the hand.
[0108] Next, the fitting of the cling wrap seizing members 7 to the end walls 8, respectively,
or the movement of the cling wrap seizing members 7 inward results in the insertion
the cylinders 10 of the cling wrap seizing members 7 into the inside of the tube 6
of the cling wrap roll 4, respectively. This results in the completion to load the
cling wrap roll 4 into the storage case 2, and the cling wrap roll 4 is held within
the storage case 2 so as not to be releasable.
[0109] In the case of using the cling wrap film 5 by cutting to a required length, as shown
in Fig. 2, the required length of the cling wrap film 5 is pulled out from the cling
wrap roll 4, and the portion of the cling wrap film 5 to be cut is placed on a pair
of the front & rear above-mentioned cutter member housing walls 19 & 20, which comprise
the cutter member housing 18. At this time, the cling wrap film 5 makes contact with
the cling wrap slip stoppers 23 and is secured.
[0110] Next, the cover 3 is rotated forward, and as shown in Fig. 3 and Fig. 4, it covers
& stops over the case 2. When this operation is performed, while the back board 38
pushes the cling wrap film 5 downward behind the rear side of the rear cutter member
housing wall 20 and a tension force is applied, the cutter member 34 is inserted in
between a pair of the front & rear cutter member housing walls 19 & 20, which comprise
the cutter member housing 18, and the cling wrap film 5 is cut off.
[0111] In this case, the cut edge of the cling wrap film 5 makes contact with the cling
wrap slip stoppers 23, arranged on the upper surface, the front side and the rear
side of the rear cutter member housing wall 20, and it is secured, so the cling wrap
roll 4 will never be rewound.
[0112] In addition, in the case of using the cling wrap film 5 by cutting to a required
length, the cover 3 is opened and the cut edge of the cling wrap film 5, which makes
contact with the cling wrap slip stoppers 23 that are arranged on the upper surface,
the front side and the rear side of the cutter member housing wall 20 and is secured,
is pulled out by grasping with fingers, and, it that case, the insertion of fingers
into the notches 21 & 22, which are formed in the cutter member housing walls 19 &
20, respectively, enables the easy grasp and pulling out.
[0113] In the case that the cling wrap film 5 is used up and the cling wrap roll 4 is replaced
with a new one, while the cling wrap seizing members 7 are extracted from the edge
walls 8 of the storage case 2, or while the cling wrap seizing members 7 are moved
outward, the cling wrap roll 4 can be easily replaced.
[0114] In the case of not using the cling wrap case 1, it is stored in the state where the
cover 3 is closed. In this case, since the
closed state of the cover 3 is secured by the lock mechanisms 39 and they can prevent the
cover 3 from easily opening, they prevent the cling wrap roll 4 from slipping off
or becoming dirty.
[0115] In the case of storage, the cling wrap case 1 can be stored by adhering onto frequently-used
equipment, such as a refrigerator, using the fastening means 25 where a magnetic force
is utilized, attached at the back surface side of the bottom 24 of the storage case
2.
