1 to 3, a closed container 10 according to an embodiment of the present invention includes a container 100 having an accommodation space 110 for accommodating cosmetics therein and an opening formed at an upper portion thereof, ; A cover 200 formed to open and close the opening and formed with a first discharge groove 230 for discharging the air inside the accommodation space 110 to the outside; A soft member 400 disposed on a bottom surface of the cover 200 and having a second discharge groove 410 formed in the first discharge groove 230 and having a hollow shape; And a button stopper 300 disposed on the upper surface of the lid 200 and configured to be opened and closed in close contact with the second discharge groove 410.

The container 100 includes an accommodation space 110 for accommodating the liquid cosmetics and an outer wall 130 for enclosing the accommodation space 110 on the outside of the container.

An opening (not illustrated) is formed in the upper part of the container 100 to serve as a passage for the cosmetics to flow in and out. The container 100 is formed with an outer wall 130 for protecting the cosmetics from the outside.

The outer wall 130 protects the cosmetics from the outside. The outer wall 130 is formed such that the first outer wall 131 and the second outer wall 133 are spaced apart from each other. Here, the first outer wall 131 is disposed on the inner side with respect to the container 100 to form the accommodation space 110. On the other hand, the second outer wall 133 is disposed on the outer side to form the outer surface of the container 100. At this time, since the first outer wall 131 and the second outer wall 133 are formed apart from each other, an empty space is formed therebetween. At this time, since the empty space is filled with air, it acts as a blocking film to prevent external heat from being transferred to the accommodation space 110. That is, even when the temperature of the outside of the container 100 rises, the sealed container 10 does not transmit heat to the liquid cosmetic product, so that the liquid cosmetic product can be stored for a long period of time.

4, the container 100 may further include a fixing portion 135 for fixing the heat insulating member 170 to the inside of the first outer wall 131. As shown in FIG. The fixing portion 135 is formed so as to be spaced inward of the first outer wall 131. That is, the fixing portion 135 forms the receiving space 110 of the container 100. The heat insulating member 170 is disposed between the fixing portion 135 and the first outer wall 131 to prevent heat from being injected from the outside.

The container 100 is formed with an air groove 190 for discharging air to the outer surface of the second outer wall 133. The air groove 190 is formed through the second outer wall 133. The air groove 190 discharges the air between the first outer wall 131 and the second outer wall 133 to the outside. At this time, it is appropriate that at least two air grooves 190 are formed uniformly on the outer peripheral surface through the second outer wall 133.

The accommodation space 110 is formed inside the first outer wall 131. The accommodation space 110 stores cosmetics inside the container 100. The accommodation space 110 stores liquid cosmetics and solid cosmetics. In this case, the liquid cosmetics include not only viscous gel cosmetics but also viscous liquid cosmetics. In addition, cosmetics include base makeup cosmetics such as foundations and point makeup cosmetics such as eye shadow and lipstick.

Referring to Figs. 5 and 6, the lid 200 is fastened to the container 100 to open and close the opening. The lid 200 is formed with a first discharge groove 230 for discharging the internal air located inside the accommodation space 110 to the outside.

The lid 200 may be integrally hinged to one side of the container 100, and the lid 200 may be screwed and threaded.

The lid 200 is formed with a cover part 150 for fixing the button stopper 300 and the opening and closing handle 210. The cover part 150 is formed to protrude from the upper part of the lid 200. At this time, the cover part 150 is formed such that a part of the upper part has a step. That is, the cover unit 150 is disposed with a button-type cap 300 inserted into the upper stepped portion. At this time, the stepped portion of the cover portion 150 sets the angle at which the button-type cap 300 rotates (see FIG. 8B). That is, the stepped portion of the cover portion 150 determines the rotation range of the button-type cap 300 together with the opening / closing handle 210. The cover portion 150 is suitably formed integrally with the opening and closing handle 210 (see Figs. 1 and 2).

The lid 200 protrudes from the outer surface to form the opening / closing handle 210. That is, at least one opening / closing handle 210 is formed in the radial direction with respect to the outer peripheral surface of the lid 200. The opening and closing handle 210 is for easily opening and closing the lid 200 by grasping the lid 200 with ease and applying an external force.

The opening / closing handle 210 is formed to extend along a stepped portion of the cover portion 150. At this time, the opening and closing handle 210 is formed to be open by a stepped portion of the cover part 150. That is, the opening / closing handle 210 is formed with a part of the inside thereof being opened, and a button-type cap 300 is inserted and disposed in the opened position. The opening / closing handle 210 limits the range of the pushing plate of the button-type plug 300 (see FIG. 8B).

The lid 200 may protrude downward to form the locking part 140. At this time, it is appropriate that the lock portion 140 is formed to extend from the cover portion 150 and partially protrude downward. The locking part 140 fastens the lid 200 and the container 100 to prevent foreign substances from entering from the outside. The locking portion 110 is formed by projecting downward from the rim of the lid 200 so as to surround the outer surface of the container 100 when the lid 200 closes the opening of the container 100. [ The inner surface of the lock portion 140 is brought into close contact with the outer surface of the container 100 to prevent foreign matter from entering the container 100.

The first discharge groove 230 is formed on the top of the lid 200. The first discharge groove (230) is formed in communication with the accommodation space (110). That is, the first discharge groove 230 serves to discharge the internal air located inside the accommodation space 110 through the discharge port 371 to the outside. The first discharge groove 230 is sealed by inserting the second discharge groove 410 and the projection 370 into the interior.

It is appropriate that the first discharge groove 230 is formed in the vicinity of the opening / closing handle 210 on the cover 200. This is because the first discharge groove 230 is engaged with the button stopper 300 and the opening and closing handle 210. It is appropriate that the first discharge groove 230 is formed in a circular shape. This is not intended to limit the shape of the first discharge groove 230 to a circular shape.

The flexible member 400 is disposed on the bottom surface of the lid 200 and is inserted into the first discharge groove 230 to form a second discharge groove 410 having a hollow shape. The soft member 400 is formed of an elastic material. The soft member 400 discharges the air inside the accommodation space 110 to the outside when the pressure plate 330 of the button-type cap 300 is pressed. When the pressing member 330 is not pressed by the elastic member 400, the connection member 400 is formed to be in close contact with the button-type cap 300 while being in contact with the elastic member 400.

The flexible member 400 is formed to seal the lid 200 and the container 100. Suitably the flexible member 400 is formed along the rim of the lid 200 to seal the container 100. At this time, the upper portion of the soft member 400 is inserted into the lid and the lower portion is formed to protrude in the direction of the container 100. That is, the lower portion of the flexible member 400 is inserted into the empty space between the first outer wall 131 and the second outer wall 133 when the lid 200 closes the opening of the container 100. This causes the lower portion of the soft member 400 to seal the accommodation space 110 from the outside. Therefore, the sealed container according to the present invention prevents the liquid cosmetics and food from leaking from the accommodation space 110 even if it is severely shaken or impacted from the outside.

The second discharge groove 410 serves as a passage for discharging the air inside the accommodation space 110 to the outside. The second discharge groove 410 is formed to be coupled with the first discharge groove 230 in correspondence with each other. That is, the second discharge groove 410 is formed to be inserted into the first discharge groove 230. At this time, it is appropriate that the second discharge groove 410 is formed to protrude above the soft member 400. This is to increase the adhesion between the second discharge groove 410 and the first discharge groove 230. The second discharge groove 410 is inserted and fixed in the hollow of the first discharge groove 230 so that the second discharge groove 410 fixes the flexible member 400 so as not to shake. In addition, the second discharge groove 410 serves as a passage for discharging the air inside the accommodation space 110 to the outside.

The second discharge groove 410 allows the lid 200 to be in close contact with the button stopper 300. That is, the button-type plug 300 is sealed using the elastic force of the second discharge groove 410 (see FIGS. 4 and 8). That is, the elastic force of the second discharge groove 410 is used to cause the button-type plug 300 to be closed downward.

The button-type cap 300 is disposed on the upper surface of the lid and is formed to be in close contact with the second discharge groove 410 to open and close. The button-type cap 300 includes a plate 310 having a flat surface; One side of the plate 310 is formed with a pressure plate 330 bent upwardly; The other side of the plate 310 includes a protrusion 370 protruding downward; And a support 350 disposed between the pressure plate 330 and the protrusion 370 and supporting the pressing force of the plate 310 downward. The button-type plug 300 discharges the air inside the accommodation space 110 to the outside (see FIG. 8B). In addition, the button-type cap 300 also plays a role of canceling the compression state of the accommodation space. That is, the button-type cap 300 keeps the inner and outer pressure states of the container 100 parallel so that the button-type cap 300 allows the container 100 and the cap 200 to be easily opened and closed. The button-type cap 300 maintains the state of the inside and outside air pressure of the container 100 in parallel so that the button-type cap 300 does not close by the air pressure when the container 100 and the cap 200 are closed .

The plate 310 is formed in a plane. The plate 310 is disposed on the top of the lid 200. A pressing plate 330, a protrusion 370 and a support 350 are formed on the surface of the plate 310. The plate 310 is suitably made of a material having rigidity.

A pressing plate is formed on one side of the plate, and a protrusion is disposed on the other side of the plate.

The pressure plate is formed by being bent to the upper side of one side of the plate. The platen provides a plane for the user to transmit pressure. The pressing plate 330 is inserted and fixed to the opening / closing handle 210 and the cover unit 150. When the pressure plate 330 is pressed, part of the pressure plate 330 is caught by the cover portion and is not released. That is, the pressure plate 330 is formed to be in close contact with the upper surface of the lid when pressurized, so that the pressure plate 330 prevents the button-type cap 300 from being detached from the opening and closing handle and the cover unit 150.

The support portion 350 is formed at an intermediate portion of the plate 310 and the support portion 350 is formed to protrude downward from the plate 310. At this time, the support portion 350 is formed to abut the groove formed in the lid 200. That is, the support portion 350 is fastened to the lid 200 and fixed.

The support portion 350 is disposed between the plate 310 and the pressure plate 330. The supporting portion 350 is suitably formed to have a curvature in a downward direction of the plate 310. The supporting portion 350 serves as a supporting point for rotating the cover 200 with respect to the cover 200. That is, the support portion 350 switches the direction of the pressing force of the pressing plate 330 in the opposite direction with respect to the supporting point. That is, the support portion 350 uses the leverage principle to open or close the protrusion 370 by contacting the second discharge groove 410.

The protrusion 370 discharges the air inside the accommodation space 110 to the outside. A discharge port 371 is formed on the outer circumferential surface of the projection 370. It is preferable that the protrusion 370 is formed on the opposite side where the pressure plate 330 is formed. The protrusion 370 is formed corresponding to the second discharge groove 410. The protrusion 370 is formed to be in sealing contact with the inner peripheral surface of the second discharge groove 410. At this time, it is appropriate that the protruding portion 370 is inserted into the second discharge groove 410 and disposed closely to the periphery.

The upper portion of the protrusion 370 is integrally formed on the lower surface of the plate 310. It is appropriate that the protruding portions 370 are formed so that the areas of the middle portion and the bottom portion are different from each other. It is preferable that the protruding portion 370 has a larger area at the lower end than the intermediate portion. That is, the upper end and the lower end of the protrusion 370 are preferably formed in a trapezoidal shape. This is because the projecting portion 370 abuts the lower end of the second discharge groove 410 to maintain the sealing force.

The discharge port 371 serves as a passage for discharging the air inside the accommodation space 110 to the outside. At this time, the discharge port 371 discharges the inside air of the accommodation space 110 to the outside when the pressure plate 330 is pressed. If the discharge port 371 is not pressed to the pressure plate, the protrusion 370) is sealed (see Fig. 8). It is appropriate that the discharge port 371 is formed in the direction opposite to the pressure plate 330. This is because the discharge port 371 facilitates discharge of the internal air to the outside when the button-type cap 300 is pressed. The discharge port 371 is formed by opening the middle portion and the lower portion of the protrusion 370. The discharge port 371 is formed by partially opening the outer circumferential surface of the protrusion 370.

That is, the upper end and the lower end of the protrusion 370 are preferably formed in a trapezoidal shape. This is because the projecting portion 370 abuts the lower end of the second discharge groove 410 to maintain the sealing force.

Referring to Figs. 9 to 11, the lower end of the protrusion 370 is formed with a deviation preventing portion 373 in the radial direction. The detachment preventing portion 373 prevents the detachable cap 300 and the cover 200 from being separated from each other. The release preventing portion 373 is formed by protruding from the outer peripheral surface of the lower end of the protruding portion 370 (see FIG. 10 or 11). At this time, it is appropriate that the separation preventing portion 373 is formed to have a plane. The release preventing portion 373 is fixed in close contact with the lower surface of the lid 200 (see Fig. 9). It is appropriate that at least one of the separation preventing portions 373 is formed. The release preventing portion 373 is preferably formed in the direction of the pressing plate 330. This is because the release-preventing portion 373 is such that the internal air pressure is discharged to the outside by the button-type cap 300 using the lever principle. That is, the release preventing portion 373 is formed in the pressing direction so that the release preventing portion 373 prevents the button-type plug 300 from being separated from the cover (see FIG. 9). The release preventing portion 373 is suitably formed on the other surface of the discharge port 371 (see FIG. 10 or 11).

The discharge port 371 serves as a passage for discharging the air inside the accommodation space 110 to the outside. At this time, the discharge port 371 discharges the inside air of the accommodation space 110 to the outside when the pressure plate 330 is pressed. If the discharge port 371 is not pressed to the pressure plate, the protrusion 370) is sealed (see Fig. 8). It is appropriate that the discharge port 371 is formed in the direction opposite to the pressure plate 330. This is because the discharge port 371 facilitates discharge of the internal air to the outside when the button-type cap 300 is pressed. The discharge port 371 is formed by opening the middle portion and the lower portion of the protrusion 370.
