[0019] FIG. 1 is a perspective view of a cosmetic container 100 according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view of the cosmetic container 100 illustrated in FIG. 1. And FIG. 3 is a perspective cross-sectional view of the engagement ring 130 illustrated in FIG. 2, and FIG. 4 is an enlarged view of a portion A in FIG. 3. FIG. 5 is a perspective cross-sectional view of the cosmetic container 100 according to the first embodiment of the present invention, and FIG. 6 is an enlarged view of a portion B in FIG. 5.

[0020] Referring to FIGS. 1 to 6, a cosmetic container 100 according to a first embodiment of the present invention includes a lower case 160 that houses contents (not shown), an engagement ring 130 that engages with the upper part of the lower case 160, and an upper case 110 that is rotatably engaged with the lower case 160 and covers the opened upper part of the lower case 160. And a mesh (not shown) or the like can be engaged with the engagement ring 130 to cover the opened upper part of the lower case 160.

[0021] The cosmetic container 100 according to this embodiment may be used alone or may be used by being engaged inside an external case (not shown). For example, the cosmetic container 100 according to this embodiment can be used as an inner case for refilling a compact container.

[0022] The lower case 160 has a circular cross-section and is equipped with a lower circumferential surface 162 and an engaging circumferential surface 166 to form an internal space in which contents (such as cosmetic liquid) can be contained. The lower circumferential surface 162 protrudes vertically from the edge of the bottom surface (not indicated in the drawing) of the lower case 160 and has a certain height. The engaging ring 130 is engaged with the upper part of the lower circumferential surface 162. The engaging circumferential surface 166 is located on the outer circumference of the lower circumferential surface 162 and has a larger diameter than the lower circumferential surface 162.

[0023] An engagement space 164 is formed between the lower circumferential surface 162 and the engagement circumferential surface 166, at a fixed interval. The engagement space 164 corresponds to a circular groove formed around the entire circumference of the lower case 160 and has a fixed depth. The ring circumferential surface 132 of the engagement ring 130 is inserted into the engagement space 164, and the ring circumferential surface 132 comes into contact with the outer circumferential surface of the lower circumferential surface 162, thereby engaging the engagement ring 130 with the lower case 160.

[0024] An engagement groove 170 having a certain depth in its longitudinal direction is formed on the engagement circumferential surface 166. The outer circumferential surface 140 formed on the engagement ring 130 is inserted into the engagement groove 170.

[0025] In the lower case 160, a seating surface 168 can be formed in the portion that engages with the rotary hinge 112 of the upper case 110. The sealing seating surface 138 of the engagement ring 130 is located on the seating surface 168. The seating surface 168 is formed to protrude outward from the engagement circumferential surface 166 of the lower case 160, thereby creating a space into which the rotary hinge 112 of the upper case 110 can engage.

[0026] The lower case can be formed from a single plastic resin, such as polypropylene (POPY).

[0027] The upper case 110 rotatably engages with the lower case 160 and covers the open opening of the lower case 160. The upper case 110 can also be formed from a single plastic resin such as polypropylene.

[0028] A rotary hinge 112 is formed protruding from one side of the upper case 110. The rotary hinge 112 rotatably engages with the lower case 160, thereby allowing the upper case 110 to rotate relative to the lower case 160.

[0029] The upper case 110 comprises an upper bottom surface 116 and an upper circumferential surface 118, thereby forming an upper space 114. Cosmetic tools such as buffs (not shown) can be stored in the upper space 114. Since the upper circumferential surface 118 has a certain height, the upper space 114 also has a certain depth. In addition, the edge of the upper bottom surface 116 protrudes upward in a curve and connects to the upper end of the upper circumferential surface 118.

[0030] A pressure projection 120 is formed at the lower end of the upper circumferential surface 118. The pressure projection 120 has a thinner thickness than the upper circumferential surface 118 and provides a sealing force while being located inside the engagement ring 130.

[0031] The engaging ring 130 comprises a ring circumferential surface 132 and an engaging upper surface 136. The ring circumferential surface 132 and the engaging upper surface 136 are connected perpendicularly to each other. The ring circumferential surface 132 is inserted into an engaging space 164 formed in the lower case 160 and abuts against the outer circumferential surface of the lower circumferential surface 162. The engaging upper surface 136 is bent perpendicularly inward from the upper end of the ring circumferential surface 132 and has a fixed length. A through hole (not indicated in the drawing) with a fixed diameter is formed in the center of the engaging upper surface 136, and the lower case 160 is opened by this through hole.

[0032] An inner circumferential surface 134 is formed at the lower part of the engaging upper surface 136. The inner circumferential surface 134 is formed to have a constant length (shorter than the ring circumferential surface 132) along the entire circumferential direction of the engaging ring 130. The inner circumferential surface 134 is located inside the ring circumferential surface 132 at a constant distance from it and is formed parallel to the ring circumferential surface 132. Therefore, a groove with a certain depth is formed between the ring circumferential surface 132 and the inner circumferential surface 134, and the upper end of the lower circumferential surface 162 of the lower case 160 is inserted into the groove by interference fit.

[0033] A seal seating surface 138 extending horizontally outward is formed on the outer surface of the ring circumferential surface 132. The horizontal member 152 of the seal member 150 sits on the seal seating surface 138. An outer peripheral surface 140 of a certain length protrudes vertically from the end of the seal seating surface 138. The seal seating surface 138 and the outer peripheral surface 140 are connected perpendicularly to each other, and the seal member 150 having an L-shaped cross-section is housed inside.

[0034] The engagement ring 130 can be formed from polypropylene material.

[0035] The sealing member 150 is located in the space formed by the sealing seating surface 138 and the outer peripheral surface 140 of the engaging ring 130, and plays a role in increasing the sealing force of the upper case 110 by contracting under pressure from the pressurizing projection 120 of the upper case 110. The sealing member 150 can be made of a softer material than the engaging ring 130, such as elastomer or silicone. Thus, the sealing member 150, which is made of a different material than the engaging ring 130, is formed integrally with the engaging ring 130 by double injection molding.

[0036] The sealing member 150 includes a horizontal member 152 and a vertical member 154 that are connected perpendicularly to each other, and are located on the sealing seating surface 138 and outer peripheral surface 140 of the engagement ring 130, respectively. An inner projection 156 is formed protruding from the inner peripheral surface of the vertical member 154. The inner projection 156 abuts against the outer peripheral surface of the pressure projection 120 of the upper case 110, thereby strengthening the sealing force of the upper case 110.

[0037] The cosmetic container 100 according to this embodiment can provide a cosmetic container that can enhance its sealing ability through a simple structure and manufacturing method.
