A cosmetic container comprising: a side surface member that forms a closed curved surface shielded from an outside so as to form a predetermined reception space for receiving a cosmetic product; a top surface member formed integrally with the side surface member on an upper portion of the side surface member, and including a cap coupling part protruding from a center region of the top surface member so as to be coupled with a cap; and a bottom member disposed on a lower portion of the side surface member so as to be fixed to the side surface member so that the reception space is shielded from the outside, wherein the bottom member is drawn inward of the side surface member by a predetermined interval, 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, wherein a fixing sill into which a fixing bar for fixing the bottom member when the bottom member and the side surface member are bonded to each other is insertable protrudes from a center region of the bottom member, characterized in that a reinforcing rib having a grid shape protruding by a predetermined height from a top surface of the bottom member except for an inside of the fixing sill, wherein the cosmetic container is configured so that a separate filling resin material is applied to a top surface of the bottom member so that the top surface of the bottom member is smooth, wherein the overlapping member is provided on a side surface thereof with a tapered surface, which has a width that is gradually narrowed toward a lower side of the overlapping member and wherein the overlapping member has an outer surface that is curved, and wherein a lower inner surface of the side surface member and the tapered surface are bonded to each other. a side surface member that forms a closed curved surface shielded from an outside so as to form a predetermined reception space for receiving a cosmetic product; a top surface member formed integrally with the side surface member on an upper portion of the side surface member, and including a cap coupling part protruding from a center region of the top surface member so as to be coupled with a cap; and a bottom member disposed on a lower portion of the side surface member so as to be fixed to the side surface member so that the reception space is shielded from the outside, wherein the bottom member is drawn inward of the side surface member by a predetermined interval, 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, wherein a fixing sill into which a fixing bar for fixing the bottom member when the bottom member and the side surface member are bonded to each other is insertable protrudes from a center region of the bottom member, characterized in that a reinforcing rib having a grid shape protruding by a predetermined height from a top surface of the bottom member except for an inside of the fixing sill, wherein the cosmetic container is configured so that a separate filling resin material is applied to a top surface of the bottom member so that the top surface of the bottom member is smooth, wherein the overlapping member is provided on a side surface thereof with a tapered surface, which has a width that is gradually narrowed toward a lower side of the overlapping member and wherein the overlapping member has an outer surface that is curved, and wherein a lower inner surface of the side surface member and the tapered surface are bonded to each other.
