    摘要: Provided is a cosmetic container including: a side surface member that forms a closed curved surface shielded from an outside so as to form a reception space; a top surface member formed integrally with the side surface member on an upper portion of the side surface member, the top surface member including a cap coupling part protruding from a center region of the top surface member; and a bottom member disposed on a lower portion of the side surface member so as to be fixed to the side surface member. The bottom member is drawn inward of the side surface member, and an overlapping member that overlaps the bottom member is formed by a double injection scheme to allow the side surface member to surround a bottom surface of the bottom member, so that the bottom member and the side surface member are integrally bonded.
