Description

Technical Field

[0001] The present invention relates to a compact case, and more particularly to a compact case that is detachably coupled to a cosmetic container and can be used to refill cosmetics in the form of compacts. Background Art

[0002] Generally, cosmetics such as foundation, cream, eye shadow, etc. are a type of cosmetics in which a cosmetic composition is impregnated in a sponge or a foam. After being filled in a powder shell, the powder shell is installed in a cosmetic container for use.

[0003] Therefore, when the cosmetics are completely consumed, the empty powder shell is removed from the cosmetics container to be separated, and a new powder shell filled with cosmetics is installed in the conventional cosmetics container, thereby making it possible to easily replenish new cosmetics in the cosmetics container.

[0004] A conventional compact shell provided for cosmetics filling is configured such that a storage container filled with cosmetics is placed in a lower shell and then covered with an upper cover to be sealed from the outside. The upper shell and the lower shell are connected as one body, and in a separate process, the storage container filled with cosmetics is transferred and fixed to the lower shell, and the upper shell and the lower shell are combined with each other to form a compact shell.

[0005] At this time, the storage container is provided as a medium for storing the cosmetics in the storage space of the lower shell in a state where the upper shell and the lower shell are connected as one body. In particular, the storage container is provided as a solid object having heat resistance corresponding to the filling temperature of the cosmetics and absorbing external vibration or impact to stably maintain the shape of the filled cosmetics.

[0006] However, since the storage container is provided as a medium for filling the cosmetics, the weight of the powder shell will increase, which makes it difficult to meet the trend of compact and lightweight powder shells.

[0007] Furthermore, the storage container and the upper and lower shells are manufactured separately, and the powder shells are manufactured through two different processes, which complicates the manufacturing process and causes cost increase.

[0008] Therefore, there is an increasing demand for a new compact shell that simplifies the process by directly filling the cosmetics in the lower shell without a storage container. Summary of the invention

[0009] The present invention has been made to improve the above-mentioned problems, and an object of the present invention is to provide a compact case that can stably maintain the shape of cosmetics directly filled without a storage container and has sufficient sealing properties.

[0010] A powder compact shell according to an embodiment of the present invention for achieving the above-mentioned purpose may include: a lower shell, comprising a bottom plate having a fixed pattern on the inner bottom surface for fixing the lower part of the cosmetics to be contained, and a side wall extending upward from the peripheral portion of the bottom plate and defining a storage space for containing the cosmetics together with the bottom plate; an upper shell, which is combined with the lower shell to seal the storage space from the outside; and a coupling section, which is respectively arranged on the lower shell and the upper shell, and detachably couples the lower shell and the upper shell.

[0011] Effects of the Invention

[0012] In the compact shell according to the exemplary embodiment of the present invention, the heat-resistant lower shell and the upper shell are combined by a combining section that can simply combine and separate them as needed, thereby accommodating cosmetics directly filled in the lower shell without a storage container.

[0013] In order to prevent deformation of the lower shell and the upper shell caused by the high-temperature filling process, the upper shell and the lower shell are respectively provided with an upper sealing structure and a lower sealing structure having high airtightness and sealing properties, so that high airtightness of the cosmetics storage space of the powder shell can be ensured. In addition, deformation suppression ribs that can suppress thermal deformation of the side wall are provided on the peripheral portion of the side wall, so that the airtightness of the storage space caused by the deformation of the lower shell can be prevented from decreasing.

[0014] In particular, the cosmetics directly contained in the lower housing can be stably fixed in the containing space by the fixing pattern on the bottom plate and the position fixing member on the inner side of the side wall. Therefore, the cosmetics directly filled in the lower housing can be prevented from being deformed or deteriorated, thereby preventing the cosmetics directly filled in the lower housing from being defective.

[0015] Therefore, the weight and size of the compact case can be reduced by directly accommodating the cosmetics in the lower case without a storage container for storing the cosmetics. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0038] Figure 11 is a perspective view showing a powder compact shell according to an embodiment of the present invention. Figure 2 It is shown in Figure 1 Exploded three-dimensional image of the powder compact shell. Figure 3a It means that Figure 2 A three-dimensional view of the lower shell of the powder shell, Figure 3b It means that Figure 3a A three-dimensional view of the back structure of the lower shell. Figure 4a It means that Figure 2 A three-dimensional view of the upper shell of the powder shell, Figure 4b It means that Figure 4a A three-dimensional view of the back structure of the upper shell. Figure 5 It will be shown in Figure 1 A cross-sectional view of the powder shell cut along the II' direction.

[0039] refer to Figures 1 to 5 According to an embodiment of the present invention, a powder shell 500 may include: a lower shell 100 having a storage space RS for storing cosmetics (not shown), an upper shell 200 that seals the storage space RS to prevent the cosmetics from drying out and being defective, and a connecting section 300 that detachably connects the lower shell 100 and the upper shell 200.

[0040] As an embodiment, the lower housing 100 has a storage space RS, and cosmetics can be directly loaded into the storage space RS for storage through a filling process. For example, the cosmetics may include impregnated cosmetics represented by foundation, cream, eye shadow, etc., in which a cosmetic composition is impregnated in a sponge or polyurethane foam. However, it is not limited to this, and various cosmetics can be used as long as they can be accommodated in the storage space RS through a filling process.

[0041] For example, the lower housing 100 may include a bottom plate 110 , a side wall 120 extending upward from a peripheral portion of the bottom plate 110 and defining a storage space RS together with the bottom plate 110 , and a lower sealing structure 130 capable of being combined with the upper housing to seal the storage space RS.

[0042] The base plate 110 may be provided as a flat plate having sufficient heat resistance at the filling temperature of the cosmetics and having appropriate strength and hardness. For example, the base plate 110 may be provided as a polyurethane photocurable resin having sufficient heat resistance at a filling temperature of about 80° C. or more and excellent tensile properties.

[0043] In particular, a fixing pattern P formed by a plurality of protrusions protruding regularly is arranged on the inner bottom surface B1 of the bottom plate 110, which can fix the lower part of the cosmetics contained in the containing space RS. Therefore, even if the powder shell 500 is moved or transferred in various ways after the cosmetics are filled in the containing space RS, the cosmetics can be stably fixed inside the containing space RS. That is, the cosmetics can be fixed by the fixing pattern P to prevent the cosmetics from being deformed during the movement of the powder shell 500.

[0044] In the present embodiment, the fixing pattern P may be provided as a checkered pattern protruding inside a specific pattern area set around the center of the bottom plate 110. However, this is merely an example, and it is obvious that various fixing patterns P may be provided as long as the lower portion of the cosmetics can be fixed inside the accommodation space RS.

[0045] The side wall 120 extends upward from the peripheral portion of the bottom plate 110 and defines a receiving space RS for receiving cosmetics together with the bottom plate 110. Therefore, the receiving space RS is defined by the bottom plate 110 and the side wall 120 and is provided as an open space with an open upper portion.

[0046] For example, the side wall 120 is provided in a form integrated with the bottom plate 110 and can be provided with the same polyurethane photocurable resin as the bottom plate 110. However, this is only an example, and the side wall 120 may be made of another material different from the bottom plate 110.

[0047] A position fixing member 122 for fixing the side of the cosmetics to suppress deformation may also be provided on the inner side of the side wall 120. The position fixing member 122 is arranged on the inner side of the side wall 120 in a manner surrounding the storage space RS, and can support the side of the cosmetics and suppress displacement at various positions of the side. Therefore, the flow of the contained cosmetics can be suppressed during the movement of the powder shell 500 to minimize deformation.

[0048] In the case of this embodiment, the position fixing member 122 may include at least one fixing ring 122 a continuously extending along the inner side surface of the side wall 120 to surround the accommodation space RS.

[0049] For example, a plurality of fixing rings 122a may be arranged at regular intervals along the inner side surface of the side wall 120. Therefore, the side portion of the cosmetics accommodated in the accommodation space RS is supported by the plurality of fixing rings 122a, and shape deformation is suppressed.

[0050] Different from this, the position fixing member 122 may also be provided as a discontinuous fixing block 122 b.

[0051] Figure 6a It means that Figure 3aA perspective view of another embodiment of the lower housing, Figure 6b It is shown in Figure 6a A top view of the lower housing.

[0052] refer to Figure 6a and 6b The lower housing 200a according to another embodiment of the present invention has the same structure as shown in FIG. 1 except that the fixing ring 122a is replaced by a fixing block 122b. Figure 3a Therefore, regarding the deformed lower housing 200a, the fixing block 122b will be mainly described.

[0053] The fixing block 122b protrudes from the inner side of the side wall 120 to have a set thickness and can extend along the height direction of the side wall 120. In the present embodiment, a plurality of fixing blocks 122b are provided at regular intervals along the inner side of the side wall 120 to intermittently surround the accommodation space RS.

[0054] Therefore, the side portion of the cosmetics loaded in the storage space RS is intermittently supported by the plurality of fixing blocks 122 b , thereby suppressing positional variation. Therefore, deformation of the cosmetics in the storage space RS can be suppressed.

[0055] The lower sealing structure 130 is fixed to the outer side of the side wall 120 and can be combined with the upper sealing structure 220 of the upper housing 200 described later. The storage space RS is sealed and isolated from the outside by the combination of the lower sealing structure 130 and the upper sealing structure 220. Therefore, the cosmetics stored in the storage space RS are also sealed from the outside and can be protected from the external environment such as moisture and temperature.

[0056] For example, the lower sealing structure 130 may include a leg cylinder 131 , a cover disk 132 , and a lower sealing ring 133 .

[0057] The leg cylinder 131 is provided in a manner of surrounding the side wall 120 separately from the side wall 120. Therefore, a separate space between the side wall 120 and the leg cylinder 131 is provided as a leg space LS, and is configured to accommodate the bottom plate 110 and the side wall 120 inside the leg cylinder 131.

[0058] At this time, the end of the leg cylinder 131 is configured to be located at a height substantially the same as or higher than the outer bottom surface B2 of the bottom plate 110, or to protrude further downward than the outer bottom surface B2. Therefore, when the powder case 50 is placed on any surface, the leg cylinder 131 contacts the outer bottom surface B2 more preferentially, and the vibration and external force transmitted to the storage space RS containing the cosmetics can be minimized.

[0059] That is, by absorbing the vibration or external force transmitted from the outside of the powder case 500 , the damage or deformation of the cosmetics accommodated in the accommodation space RS due to the external force can be minimized.

[0060] The cover plate 132 is connected to the outer side surface of the side wall 120 and the leg cylinder 131, respectively, and can fix the leg cylinder 131 to the side wall 120. The leg cylinder 131 is arranged in a manner separated from the side wall 120, but can also be fixed to the side wall 120 by the cover plate 132. Therefore, the leg space LS is covered by the cover plate 132 and is formed into a space that is closed at the top and open at the bottom.

[0061] The cover plate 132 has a plate shape having a flat upper surface, and a lower sealing ring 133 is disposed on the upper surface of the cover plate 132 and is separated from the side wall 120 by a certain distance to provide a lower coupling gap LG.

[0062] The lower sealing ring 133 is provided in a ring shape having a set radius and surrounding the upper end portion of the sidewall 120. Therefore, a lower coupling gap LG provided between the lower sealing ring 133 and the sidewall 120 is also formed as a space having a certain volume.

[0063] A second upper seal ring 222 of an upper seal structure 220 described later is inserted into the lower coupling gap LG by interference fitting, so that the accommodation space RS can be sealed from the external environment.

[0064] A plurality of deformation suppression ribs 140 connected to the outer side surface of the side wall 120 and the inner side surface of the leg cylinder 131 and arranged at regular intervals along the outer periphery of the leg cylinder 131 may be arranged in the leg space LS.

[0065] The process of filling the storage space RS with cosmetics is performed at a high temperature of 80° C. or higher, so the shapes of the bottom plate 110 and the side wall 120 may be deformed due to temperature changes. The deformation of the bottom plate 110 and the side wall 120 may reduce the airtightness of the storage space RS, and may deform or change the properties of the stored cosmetics, resulting in defective cosmetics.

[0066] A plurality of deformation suppression ribs 140 are arranged along the outer side surface of the side wall 120 to suppress deformation of the side wall 120. The deformation suppression ribs 140 are supported by the leg cylinders 131, and the rigidity of the deformation suppression ribs 140 and the leg cylinders 131 suppresses deformation of the side wall 120.

[0067] By suppressing the deformation of the side wall 120, it is also possible to suppress the deformation of the bottom plate 110 integrally connected to the side wall 120. Therefore, it is possible to suppress the deformation of the side wall 120 and the bottom plate 110 to improve the sealing property and airtightness of the storage space RS.

[0068] A plurality of friction blocks 150 are disposed on the outer side of the leg cylinder 131 to increase friction with the cosmetic container (not shown) in contact with the lower housing 100. The powder housing 500 is ultimately stored in a cosmetic container as an external container for use, so the powder housing 500 needs to be stably fixed inside the cosmetic container.

[0069] Therefore, by disposing a plurality of friction blocks 150 as external walls that are in contact with the lower shell 100 and that can increase the friction with the cosmetic container, for example, on the outer side surface of the lower shell 100 located below the powder shell 500, the mobility on the lower shell 100 inside the cosmetic container can be improved. Therefore, the storage stability of the powder shell 500 in the cosmetic container can be improved.

[0070] As an embodiment, the upper housing 200 may include a top plate 210 covering the lower housing 100 and an upper sealing structure 220 extending downward from the top plate 210 and combined with the lower sealing structure 130 to seal the accommodation space RS.

[0071] The top plate 210 has a shape corresponding to the plane shape of the lower housing and can be fastened to the upper portion of the lower housing 100 with high accuracy to seal the accommodation space RS from the outside. For example, the top plate 210 can be made of polyurethane photocurable resin having high hardness and strength and excellent heat resistance like the bottom plate 110 and the side wall 120.

[0072] The upper sealing structure 220 may include a first upper sealing ring 221 , a second upper sealing ring 222 , and a third upper sealing ring 223 which are fixed to surround the peripheral portion of the top plate 210 and extend downward.

[0073] For example, the upper sealing structure 220 may be configured with a third upper sealing ring 223 that is integrally configured along the peripheral portion of the top plate 210 and accommodates the top plate 210 internally, and may include a second upper sealing ring 222 and a first upper sealing ring 221 that are connected to the lower portion of the top plate 210 on the inner side of the third upper sealing ring 223 and are configured in a manner separated from each other by a certain interval.

[0074] The first upper sealing ring 221 protrudes downward from the top plate 210 and extends along the inner surface of the side wall 120 in a ring shape having a first radius from the center of the top plate. Therefore, the first upper sealing ring 221 can contact the inner surface of the side wall 120 and act as a primary sealing portion for the storage space RS.

[0075] The second upper sealing ring 222 has a second radius larger than the first radius, and protrudes downward from the top plate 210 in a ring shape separated from the first upper sealing ring 221. The second upper sealing ring 222 is inserted and coupled to the lower coupling gap LG by interference fit. Therefore, the second upper sealing ring 222 can supplement the airtightness of the first upper sealing ring 221 and act as a secondary sealing portion for the accommodation space RS.

[0076] The third upper sealing ring 223 has a third radius larger than the second radius, and protrudes downward from the top plate 210 in a ring shape separated from the second upper sealing ring 222. The third upper sealing ring 223 contacts the outer side surface of the lower sealing ring 133, and can complement the airtightness of the second upper sealing ring 222 to act as a tertiary sealing portion for the accommodation space RS.

[0077] The 1st to 3rd upper sealing rings 221, 222, 223 are respectively inserted into the inner wall of the side wall 120, the lower coupling gap LG and the outer side surface of the lower sealing ring 133 in a contact manner, so that the side wall 120 is combined in the inner upper gap UG1 serving as the separation space between the 1st and 2nd upper sealing rings 221, 222 by interference fit, and the lower sealing ring 133 is combined in the outer upper gap UG2 serving as the separation space between the 2nd and 3rd upper sealing rings 222, 223 by interference fit.

[0078] Therefore, the lower sealing ring 133 on the lower shell 100 is combined with the upper sealing structure 220 by interference fit, and the first to third upper sealing rings 221, 222, 223 on the upper shell are combined with the lower sealing structure 130 by interference fit, so that the airtightness of the combination of the lower shell 100 and the upper shell 200 can be fully maintained at a high level.

[0079] Therefore, the storage space RS can be triple-sealed from the outside by the combination of the upper sealing structure 220 and the lower sealing structure 130. Therefore, when the cosmetics are directly loaded into the lower housing 100, even if the upper housing and the lower housing are deformed due to the high temperature of the loading process, the triple-sealing structure using the first to third upper sealing rings 221, 222, and 223 can prevent the cosmetics stored in the storage space RS from being deformed or deteriorating in composition.

[0080] In particular, by configuring the lower sealing ring 133 and the first to third upper sealing rings 221, 222, 223 to have different hardnesses, the sealing force for the storage space RS can be further improved. When the lower sealing ring 133 having different hardnesses is combined with the first to third upper sealing rings 221, 222, 223, the gap between the storage space RS and the outside can be blocked by configuring the softer sealing ring to surround the contact area with the harder sealing ring. Therefore, by configuring any one of the lower sealing ring 133 and the first to third upper sealing rings 221, 222, 223 to be made of a material with high hardness and configuring the other one to be made of a material with low hardness, the sealing characteristics of the storage space RS can be further improved according to the characteristics of the materials.

[0081] As an embodiment, the combining section 300 can detachably combine the lower housing 100 and the upper housing 200 .

[0082] For example, the coupling section 300 may include a coupling base 310 fixed to the leg cylinder 131 and having a rotation shaft 312 , and a rotation cylinder 320 fixed to the top plate 210 and detachably coupled to the rotation shaft 312 .

[0083] The coupling base 310 may include a shaft fixing portion 311 protruding from an outer side surface of the leg cylinder 131 and a rotating shaft 312 fixed to the shaft fixing portion 311 .

[0084] The rotating cylinder 320 includes a detachable portion CO partially opened along the longitudinal direction of the rotating shaft 312 , and the rotating shaft 312 can be selectively coupled to the rotating cylinder 320 via the detachable portion CO.

[0085] Figure 7 is a diagram showing an embodiment of the present invention. Figure 1 A cross-sectional view of a rotating cylinder of a combined section. Figure 8a is the axis of rotation and is shown in Figure 7 The rotating cylinder is combined with the previous state diagram, Figure 8b is the axis of rotation and is shown in Figure 7 A diagram showing the state of the rotating cylinder after it is combined.

[0086] refer to Figure 7 , 8a and 8b, the rotating cylinder 320 may include: a connecting portion 321 extended from the side of the third upper sealing ring 223 in a manner corresponding to the rotating shaft 312, a first cylindrical portion 322 connected to the connecting portion 321 and having a coupling space S1 inside, a second cylindrical portion 323 connected to the first cylindrical portion 323 and having an entry space S2 inside, and a protrusion OP protruding from the inner side surface of the boundary portion between the first cylindrical portion 322 and the second cylindrical portion 323.

[0087] The connecting portion 321 extends outward from the third upper sealing ring 223 in a manner covering the rotating shaft 312, and is provided in the shape of a flat plate having a width corresponding to the length of the rotating shaft 312. The first and second cylindrical portions 322 and 323 have a length corresponding to the width of the flat plate of the connecting portion 321, and are provided in the shape of a cylinder connected to the connecting portion 321 as a whole.

[0088] In the case of the present embodiment, the first and second cylindrical portions 322 and 323 are integrally connected to the connection portion 321 , and are provided in a cylindrical shape having an internal space for accommodating the rotating shaft 312 .

[0089] The first cylindrical portion 322 may be integrally connected to the connecting portion 321 and include a coupling space S1 for accommodating the rotating shaft 312 and coupling the rotating cylinder 320 to the coupling base 310. The coupling space S1 is provided to have a size larger than the rotating shaft 312, and the rotating cylinder 320 can rotate around the rotating shaft 312.

[0090] The second cylindrical portion 323 may be connected to the first cylindrical portion 322 as a whole, and has an entry space S2 that can be continuously connected to the loading and unloading portion CO. The entry space S2 is configured to communicate with the loading and unloading portion CO of the rotating cylinder 320, and the rotating shaft 312 can enter the entry space S2 from the outside through the loading and unloading portion CO.

[0091] The protrusion OP protrudes from the inner side surface of the boundary portion between the first cylindrical portion 322 and the second cylindrical portion 323 toward the center of the first cylindrical portion 322 and the second cylindrical portion 323 , and is provided in a ring shape surrounding the coupling space S1 and the entry space S2 .

[0092] Therefore, the size of the boundary space S3 , which is a boundary region between the combining space S1 and the entering space S2 , is reduced to be smaller than the combining space S1 and the entering space S2 due to the protruding portion OP.

[0093] That is, the supporting protrusion OP is disposed in the boundary region between the first and second cylindrical portions 322 and 323 to support the rotating shaft 312 coupled to the coupling space S1 , thereby preventing the rotating shaft 312 from being separated from the entry space S2 .

[0094] In the case of this embodiment, the first cylindrical portion 322 and the second cylindrical portion 323 are made of an elastic body and can be stretched within an elastic range by an external force. Therefore, when an external force is applied to the rotating cylinder 320, the boundary space S3 is expanded by the elastic stretching of the first cylindrical portion 322 and the second cylindrical portion 323, and the rotating shaft 312 selectively moves between the first cylindrical portion 322 and the second cylindrical portion 323 through the expanded boundary space S3.

[0095] When the external force applied to the rotating cylinder 320 is released, the first cylindrical portion 322 and the second cylindrical portion 323 return to their original shapes, and the size of the boundary space S3 also returns to its original size, and becomes smaller than the coupling space S1 and the entry space S2.

[0096] Therefore, the rotating shaft 312 disposed in the coupling space S1 inside the first cylindrical portion 322 is supported by the protruding portion OP, and can be suppressed from escaping into the entry space S2 inside the second cylindrical portion 323. Furthermore, the movement of the rotating shaft 312 disposed in the entry space S2 is suppressed by the protruding portion OP, and the movement into the coupling space S1 is suppressed unless an external force is applied.

[0097] like Figure 8a and 8b As shown, the rotating cylinder 320 and the rotating shaft 312 can be detachably coupled as follows.

[0098] First, the second cylindrical portion 323 of the rotating cylinder 320 is inserted into the rotating shaft 312 so that the rotating shaft 312 is located in the entry space S2. When the rotating cylinder 320 and the rotating shaft 312 are coupled to each other, the rotating shaft 312 is located in the entry space S2 through the attachment and detachment portion CO. At this time, the rotating shaft 312 is located in contact with the protrusion OP in the entry space S2, and the entry into the coupling space S1 is restricted by the protrusion OP.

[0099] Next, an external force for coupling is applied to the rotating cylinder 320 to force the rotating shaft 312 to enter the coupling space S1. If the connecting portion 321 is pressurized downward, the protrusion OP will also extend within the elastic deformation range of the first and second cylindrical portions 322 and 323, thereby expanding the size of the boundary space S3. Therefore, the rotating shaft 312 can move from the entry space S2 to the coupling space S1.

[0100] If the rotating shaft 312 is inserted into the connecting space S1 through the expanded boundary space S3, the external force applied to the rotating cylinder 320 is released, so that the first and second cylindrical parts 322 and 323 return to their original shapes. Therefore, the protrusion OP also returns to its original position, and the connecting space S1 is also reduced to its original size. Therefore, the rotating shaft 312 arranged in the connecting space S1 is supported by the protrusion OP and can be prevented from escaping from entering the space S2.

[0101] When the rotating cylinder 320 is separated from the rotating shaft 312, an external force is applied to the rotating cylinder 320 to extend the first and second cylindrical portions 322 and 323 to expand the protrusion OP, thereby expanding the boundary space S3. Therefore, the rotating shaft 312 disposed in the coupling space S1 can be separated from the entry space S2 through the expanded boundary space S3 and discharged from the entry space S2 through the loading and unloading portion CO.

[0102] At this time, the rotating shaft 312 moves between the entry space S2 and the coupling space S1 along the surface of the protrusion OP, and thus the surface can be configured in a rounded shape to minimize friction during the movement.

[0103] Therefore, the lower shell 100 and the upper shell 200 can be detachably connected by selectively connecting the base 310 and the rotating cylinder 320. In the conventional filling process, if the lower shell 100 and the upper shell 200 are not separated, it is difficult to fill the cosmetics directly into the lower shell 100 due to the process characteristics. Due to such process restrictions, the conventional powder shell is formed by sequentially performing a first process of filling the cosmetics into the storage container and a second process of storing the storage container filled with the cosmetics in the lower shell.

[0104] However, in the powder shell 500 according to the exemplary embodiment of the present invention, the lower shell 100 and the upper shell 200 can be simply combined or separated by the combining section 300. Therefore, the powder shell 500 can be easily manufactured by directly loading the cosmetics into the lower shell 100 separated from the upper shell and then combining the upper shell 200 with the lower shell 100 filled with the cosmetics.

[0105] Therefore, the process of manufacturing powder case 500 can be simplified and the manufacturing cost can be reduced.

[0106] In the compact shell according to the embodiment of the present invention, the lower shell 100 and the upper shell 200 having high heat resistance are combined by a combining section that can simply combine and separate them as needed, thereby being able to accommodate cosmetics directly filled in the lower shell without a storage container.

[0107] In order to prevent deformation of the lower shell and the upper shell caused by the high-temperature filling process, by configuring an upper sealing structure 130 and a lower sealing structure 220 with high airtightness and sealing properties on the upper shell and the lower shell respectively, high airtightness of the cosmetics containing space RS of the powder shell 500 can be ensured.

[0108] Furthermore, by disposing the deformation suppression rib 140 that can suppress thermal deformation of the side wall at the peripheral portion of the side wall 120 , it is possible to prevent the airtightness of the storage space RS from being reduced due to deformation of the lower housing 100 .

[0109] In particular, the cosmetics directly contained in the lower housing 100 can be stably fixed in the containing space RS by the fixing pattern P provided on the bottom plate 110 and the position fixing member 122 provided on the inner side surface of the side wall 120. Therefore, by preventing the contained cosmetics from being deformed or deteriorated, it is possible to prevent the cosmetics directly loaded in the lower housing from being defective.

[0110] Therefore, the cosmetics can be directly accommodated in the lower housing 100 without a storage container for storing the cosmetics, thereby reducing the weight and size of the compact housing.

[0111] In the above, the preferred embodiments of the present invention are described in detail with reference to the accompanying drawings, but those skilled in the art should understand that various modifications and changes can be made to the present invention without departing from the scope of the idea and field of the present invention as described in the following claims.
