[0062] That is, unlike a cosmetic container according to the related art, the cosmetic container according to the present invention is provided with the air circulation surface 30 formed on the first oblique surface 14a of the first sealing protrusion 14 of the inner container 10, such that air is circulated on the entire air circulation surface 30 while the inner container lid 20 makes point contact with the fine protrusions of the air circulation surface 30 when the inner container lid 20 is opened or closed. Thus, the inner container lid 20 is prevented from being lifted up by the compressed air, so that the sealing strength is improved and the opening/closing sensitivity of the inner container lid 20 is more improved.

[0063] As shown in FIG. 7, when the inner container lid 20 is opened, the second sealing protrusion 24 formed on the sealing protrusion wheel 22 of the inner container lid 20 goes over the first sealing protrusion 14 formed on the outer wall 13 of the inner container 10. In this case, the second oblique surface 24a of the second sealing protrusion 24 makes contact with the air circulation surface 30 formed on the first oblique surface 14a of the first sealing protrusion 14, so that outside air is uniformly introduced into the entire inner container 10 through the fine protrusions of the air circulation surface 30.

[0064] Similarly, as shown in FIG. 9, when the inner container lid 20 is closed, the second sealing protrusion 24 formed on the sealing protrusion wheel 22 of the inner container lid 20 goes over the first sealing protrusion 14 formed on the outer wall 13 of the inner container 10. In this case, the second oblique surface 24a of the second sealing protrusion 24 makes contact with the air circulation surface 30 formed on the first oblique surface 14a of the first sealing protrusion 14, so that the compressed air is discharged through the fine protrusions of the air circulation surface 30 while being uniformly distributed into the inside of the inner container 10.

[0065] The air circulation surface 30 is injection-molded through a mold having a molding space, a part of which is corroded by chemical, or injection-molded through a mold having a molding space, a part of which is sanded.

[0066] That is, the inner container 10 of the cosmetic container is injection-molded through the mold having a molding space, where a portion corresponding to the first oblique surface 14a of the inner container 10 in the molding space is treated with chemical to be corroded (the surface of the metal is oxidized or altered chemically or electrically), or sanded, such that the air circulation surface 30 including the fine protrusions and grooves is formed on the first oblique surface 14a of the inner container 10 while the inner container 10 is injection-molded by injecting melt resin into the molding space of the mold.

[0067] Hereinafter, a method of assembling the cosmetic container having an air circulation surface configured as described above will be described with reference to the accompanying drawings.

[0068] As shown in FIGS. 4 and 5, to assemble the cosmetic container having an air circulation surface according to an embodiment of the present invention, the impregnation member 60 impregnated with a cosmetic material is inserted to the inside of the inner container 10, or the inner container 10 is directly filled with a cosmetic material, and then, the fixing member 70 is coupled to the inner wall 12 of the inner container 10.

[0069] In this case, the first sealing protrusion 14 is formed on the inner periphery of the upper portion of the outer wall 13 of the inner container 10, and the air circulation surface 30 is formed on the entire first oblique surface 14a of the first sealing protrusion 14.

[0070] Describing in detail the process of forming the air circulation surface 30 in the inner container 10, by treating the portion corresponding to the first oblique surface 14a of the inner container 10 in the molding space with chemical to be corroded (the surface of the metal is oxidized or altered chemically or electrically), or sanding the portion, the air circulation surface 30 including the fine protrusions and grooves is formed on the first oblique surface 14a of the inner container 10 while the inner container 10 is injection-molded through the mold.

[0071] Next, the inner container lid 20 is hinge-coupled to one side of the inner container 10, where the first hinge bracket 137 of the inner container 10 is hinge coupled to the second hinge bracket 27 of the inner container lid 20.

[0072] Then, the inner container 10 and the inner container lid 20 coupled to each other as described above is coupled to the inside of the container main body 40 having one side to which the container lid 50 is hinge-coupled.
