BACKGROUND OF THE INVENTION
[0001] The present invention disclosed herein relates to a compact case, and more particularly,
to a compact case in which a sealing member opening/closing an upper end of a contents
storage part is coupled with screws to a contents storage part, such that an open
upper end of the contents storage part can be sealed by the screw combination of the
contents storage part and the sealing member when a lower case is rotated, and thereby,
it is possible not only to improve the internal airtightness of the contents storage
portion but also to prevent leakage of contents during the decompression process.
[0002] Generally, a compact case refers to an article that stores color cosmetics or powder
used for facial makeup for women to easily carry.
[0003] The compact cases are being provided in various shapes, and store contents of powder
or color cosmetics regardless of their shape. When using a compact case, a user pressurizes
a button provided on the front surface portion of the container body to open the external
cover from the container body by hinge pivoting, and applies cosmetics for facial
makeup using cosmetic tools such as a puff or a brush contained in the container body.
[0004] Conventional compact cases as in the above are configured to maintain internal airtightness
by covering the upper end portion of the content storage part by means of an inner
cap. In this case, it is possible to block air from entering the inside to a certain
extent, but internal airtightness cannot be perfectly maintained due to a structural
limitation.
[0005] Recently, "a compact container, which is configured to contain and discharge liquid
contents in/out of the compact case while blocking the inflow of air, is disclosed
in Korean Patent No.
10-1333044.
[0006] The registered patent is characterized to comprise a lower case, receiving a contents
storage part where contents are stored, and forming a guide protrusion at an inner
lower end thereof to raise/lower a contents storage part; a middle case rotatably
coupled at an upper portion of the lower case; a contents storage part storing contents
and received to the lower case, and forming a rotation protrusion moving along the
guide protrusion; a rotation body mounted on an upper portion of the middle case,
interlocked and rotated together when the middle case rotates, and guiding a vertical
movement of the contents storage part; a sealing member coupled with screws to one
side of the rotation body to open/close an upper end of the rotation body; and an
upper case hinge-coupled to one side of the middle case, and rotating to one side
or the other side direction by pressurization of a user and rotating together with
the middle case.
[0007] The registered patent is configured in a way that when a rotation body rotates, a
contents storage part rotates together by an ascending/descending protrusion of the
contents storage part which is inserted to a guide groove of the rotation body, and
when the contents storage part rotates, a rotation protrusion formed at a lower end
of the contents storage part moves along on a sloped surface of the guide protrusion
of a lower case. Therefore, the contents storage part ascends and thereby an upper
end of the contents storage part is sealed by a sealing part of a sealing member.
[0008] However, the above-mentioned registered patent has a complicated structure for the
airtight property, which incurs a problem of increasing in manufacturing time and
cost.
[0009] Meanwhile, recently there has been an increasing tendency to accommodate the urethane
foam impregnated with liquid contents in the interior, and also various sealing structures
are being developed in order to solve the problem that contents stored in a contents
storage part are leaked during a decompression test due to the limitation of sealing
structures.

[0025] Referring to FIGS. 1 to 6, a compact case according to an exemplary embodiment of
the present invention may include a lower case 100, a middle case 200, a contents
storage part 300, a sealing member 400, an upper case 500, and a support body 600.
[0026] The lower case 100, receiving a contents storage part 300, is provided with a coupling
protrusion 110 where the contents storage part 300 is coupled such that the contents
storage part 300 can rotate together according to rotation of the lower case 100 at
an inner side thereof.
[0027] Furthermore, at an inner side of the lower case 100 is provided an insertion groove
120 where an insertion protrusion 610 of a support body 600 is inserted such that
the support body 600 can rotate together according to rotation of the lower case 100,
and at an inner side is provided a separation-preventing groove 130 where a separation-preventing
protrusion 620 of the support body 600 is coupled such that the support body 600 can
be prevented from being separated to an upward direction in a state that the insertion
protrusion 610 is inserted to the insertion groove 120.
[0028] Meanwhile, at the lower case 100 is provided a first protrusion part 140 which meets
a first rotation-limiting protrusion 230 and limits rotation of the lower case 100
in a rotational process thereof, and the first protrusion part 140 is preferably configured
to be in pair which protrude to be faced each other as illustrated in FIG. 1.
[0029] The middle case 200, made of shape of a ring and rotatably coupled to an upper portion
of the lower case 100, is provided with a hinge part 210 such that a sealing member
400 and an upper case 500 can be hinge-coupled at an upper end thereof and swiveled
upwards and downwards, and further provided with a penetration groove 220 such that
an opening/closing protrusion 520 of the upper case 500 can be penetrated.
[0030] In the present invention, it is characterized to be provided with a first and a second
rotation-limiting protrusion 230, 240 at an inner side of the middle case 200 so as
to limit the rotational range of the lower case 100 and the contents storage part
300. The first and the second rotation-limiting protrusions 230, 240, which are placed
in the above and the below, respectively limits the rotational range of the lower
case 100 and the contents storage part 300, and are configured to be preferably in
pair which are formed with protrusion so as to correspond each other inside the middle
case 200.
[0031] The contents storage part 300, coupled to an inner side of the lower case 100 and
storing a contents absorption member 700 impregnated with liquid contents, is provided
with a coupling groove 320 which is coupled with a coupling protrusion 110 of the
lower case 100 at an outer circumferential surface thereof such that the contents
storage part 300 can be coupled to an inner side of the lower case 100.
[0032] The contents absorption member 700 which is stored in the contents storage part 300
can be made of various materials such as puff, sponge, foam, and brush where liquid
contents are impregnated, and preferably made of porous material which easily absorbs
liquid contents.
[0033] Furthermore, at an inner side of the contents storage part 300 is provided a fixation
tube 800 which encases the contents absorption member 700 so as to fix the contents
absorption member 700, and at an upper portion of the fixation tube 800 is provided
a fixation protrusion 810 to an inward direction such that the fixation protrusion
810 supports an upper end of the contents absorption member 700 and thereby prevents
the contents absorption member 700 from being separated from the contents storage
part 300.
[0034] In the present invention, it is characterized in that at an outer circumferential
surface of the contents storage part 300 is provided a first screw thread 310 for
being screw-coupled with the sealing member 400. As the contents storage part 300
interlocked with the lower case 100 rotates when rotating the lower case 100, the
first screw thread 310 and a second screw thread 430 of the sealing 400 get screw-coupled,
and perform a sealing process through a screw-coupling, thereby effectively preventing
the contents stored in the contents storage part 300 from being leaked in a process
of decompression.
[0035] Meanwhile, at an outer circumferential surface of the contents storage part 300 is
provided a pair of second protrusion parts 330 which meet second rotation-limiting
protrusions 240 and limit the rotation of the contents storage part 300 during a rotation
process by the rotation of the lower case 100, as illustrated in FIG. 5.
[0036] Meanwhile, as illustrated in FIG. 9, when all the contents, which are impregnated
in the contents absorption member 700 stored in the contents storage part 300, are
used up, it is possible to exchange the contents absorption member 700. In this case,
it is possible easily to exchange the contents absorption member 700', by separating
the contents storage part 300 from the lower case 100 in a state of swiveling the
sealing member 400 upwards, and then by coupling with combined-fit the contents storage
part 300 which stores a new contents storage part 700' impregnated with liquid contents.
[0037] As in the above, when the exchange of the contents absorption member 700 is complete,
it is possible to use the contents impregnated in the contents absorption member 700'
after a sealing tape (S) which is attached on an upper end of the contents storage
part 300 to prevent the evaporation of the contents impregnated in the contents absorption
member 700'.
[0038] The sealing member 400 is hinge-coupled to the middle case 200 to open/close the
open upper end of the contents storage part 300, wherein a handle part 410 is provided
at a front surface thereof for easy controlling when swiveling upwards and downwards
according to the hinge combination, and a reception groove 420 is provided at an upper
portion thereof such that a contents application member 900 such as puff can be received
therein.
[0039] In the present invention, it is characterized in that at an inner circumferential
surface of the sealing member 400 is provided a second screw thread 430 which is screw-coupled
with the first screw thread 310 of the contents storage part 300. As illustrated in
the above, since a sealing process is performed by closing the open upper end of the
content storage part 300 by means of the screw combination, it is possible to effectively
prevent the contents stored in the contents storage part 300 from being leaked in
a process of decompression.
[0040] The upper case 500, which encases the contents application member 900 and is hinge-coupled
to the middle case 200 for being able to be swiveled upwards and downwards, allows
the contents application member 900 to be used when swiveled upwards to be opened,
and protects the contents application member 900 from external impact and also prevents
foreign substance from entering a reception groove 420 when swiveled downwards to
be closed. In addition, it is preferable that a mirror 510 is installed at an inner
side of the upper case 500 for a user to check her make-up area when applying contents
on her face.
[0041] In the present invention, it is characterized in that at a front surface of the upper
case 500 is provided an opening/closing protrusion 520 which controls opening/closing
of the upper case 500. The opening/closing protrusion 520, as illustrated in FIG.4,
is supported by a protrusion 630 of a support 600 in a normal state and prevents the
upper case 500 from being opened. Then, when broken away from the protrusion 630 by
the rotation of the upper case 500 and placed in a guide groove 640, the opening/closing
protrusion 520 allows the upper case 500 to open.
[0042] The support 600 is made of a ring shape which is coupled to an inner side of the
lower case 100 and rotates together by rotation of the lower case 100. At an outer
circumferential surface of the support body 600, as illustrated in FIG. 6, is provided
an insertion protrusion 610 which is inserted to an insertion groove 120 of the lower
case 100 for being able to rotate together according to rotation of the lower case
100.
[0043] Furthermore, at an outer side of the support body 600 is provided a separation-preventing
protrusion 620 which is inserted to a separation-preventing groove 130 of the lower
case 100 such that the support body 600 is prevented from moving upwards and being
separated from the lower case 100.
[0044] Meanwhile, at an outer circumferential surface of the support body 600 is provided
a protrusion 630 which supports the opening/closing protrusion 520 of the upper case
500 and prevents the upward swiveling of the upper case 500, wherein at a dead end
of the protrusion 630 is provided a guide groove 640 which guides an upward swiveling
of the upper case 500.
[0045] Hereinafter, referring to FIGS. 7 and 8, a method of using a compact case according
to an exemplary embodiment of the present invention will be described.
[0046] First, as illustrated in FIG. 7, when the lower case 100 is rotated to one side direction
in a state of grabbing the upper case 500, the contents storage part 300 which is
interlocked with the lower case 100 rotates together. Due to this, the first screw
thread 310 of the contents storage part 300 and the second screw thread 430 of the
sealing member 400 are released from the screw-combination and thereby the sealing
member 400 ascends in a narrow range.
[0047] At this, the lower case 100, as illustrated in FIG. 5, rotates up to the point where
the first protrusion part 140 meets the first rotation-limiting protrusion 230.
[0048] As in the above, when the first screw thread 310 of the contents storage part 300
and the second screw thread 430 of the sealing member 400 are released from the screw-combination,
a user swivels in an upward direction, and opens the upper case 500 and the sealing
member 400 in order, and as illustrated in FIG. 8, can smear the contents impregnated
in the contents absorption member 700 by means of the contents application member
900 and apply onto her face.
[0049] Next, after completing application of contents by means of the contents application
member 900, a user swivels the sealing member 400 to a downward direction and receives
the contents application member 900 in the reception groove 420, and then swivels
the upper case 500 to an upward direction.
[0050] As described in the above, if the lower case 100 is rotated to the other direction
after grabbing the upper case 500 in a state of swiveling the upper case to a downward
direction, as the contents storage part 300 interlocked with the lower case 100 rotates
together, the first screw thread 310 of the contents storage part 300 and the second
screw thread 430 of the sealing member 400 get screw-coupled and make the sealing
member 400 descend in a narrow range. Due to this, the sealing process is performed
in accordance with the closing of the open upper end of the contents storage part
300 by the sealing member 400.
[0051] The present invention, as described in the above, as the open upper end of the contents
storage part 300 gets closed by a sealing structure by means of a screw combination
of the contents storage part 300 and the sealing member 400, it is possible to effectively
prevent the leakage of contents.
[0052] As described above, optimal embodiments have been disclosed in the drawings and the
specification. Although specific terms have been used herein, these are only intended
