Description

Cosmetic Receptacle The present invention relates to a cosmetic container, and more specifically, to a cosmetic container in which a piston is installed inside a container in which a cosmetic is stored, and the cosmetic can be dispensed little by little by raising the piston inside the container by operation of a user. Cosmetics are manufactured in various forms such as powder, liquid, gel or cream, and solid, and are stored in cosmetic containers suitable for each form and use. Cosmetics stored in a cosmetic container are dispensed by the user little by little as needed. As one means of dispensing such cosmetics, a method has been devised in which a piston is installed inside the container in which the cosmetics are stored, and the piston is raised inside the container by the user's operation. FIG. 11 is an exploded view of a conventional cosmetic container, and FIG. 12 is a cross-sectional view of a conventional cosmetic container. A conventional cosmetic container comprises an outer container (110) having an outer container bottom surface (112), an inner container (120) installed inside the outer container (110), a spiral groove member (140) and a spiral protrusion member (150), a piston (130) installed inside the inner container (120) having a circular piston head (131), a concave discharge cap (161) coupled to the top of the inner container (120), and a concave over cap (162) coupled to the top of the outer container (110) to surround the discharge cap (161). The outer container (110) has, in addition to the outer container bottom surface (112), a tubular outer container side surface (111) and an outer container support tube portion (113) formed on the upper surface of the outer container bottom surface (112). The outer container bottom surface (112) extends from the bottom of the outer container side surface (111). The container (120) has a tubular container side portion (121), a container bottom portion (122) extending from the bottom of the container side portion (121), and a container bottom tube portion (123) extending downward from the bottom of the container bottom portion (122). The contents side portion (121) has contents side serrations (121a) formed on the upper outer surface. The inner surface of the container bottom tube section (123) has a container bottom tube serration (123a) formed along the height direction. The inner container (120) is installed such that the inner container side portion (121) is positioned inside the outer container side portion (111) and the inner container bottom portion (122) is positioned above the outer container bottom portion (112). The spiral groove member (140) is formed in a tubular shape, and a rising spiral groove (141a) is formed on the outer surface. The spiral groove member (140) is installed on the outer side of the outer container support tube (113) so as to rotate together with the outer container (110). The spiral protrusion member (150) is formed in a tubular shape, and a rising spiral protrusion (151a) is formed at the bottom of the inner surface, and a protrusion member serration (151b) is formed along the height direction on the outer surface. The spiral protrusion member (150) is installed such that the upward-acting spiral protrusion (151a) is inserted into the lower end of the upward-acting spiral groove (141a), and the protrusion member serration (151b) engages with the bottom tube serration (123a). The piston (130) has a piston head (131) and a piston wing portion (132) extending outward from the piston head (131). The piston (130) is installed such that the piston wing portion (132) contacts the inner surface of the container side portion (121), and a storage space (128) is formed on the upper side of the piston head (131). A discharge hole (161a) is formed in the discharge cap (161). The discharge cap (161) can rotate together with the container (120) through the container side serrations (121a). A method of using a conventional cosmetic container having the above-described configuration is explained as follows with reference to FIG. 13. First, the overcap (162) is separated from the outer container (110). Next, hold the discharge cap (161) and rotate the outer container (110). When the outer container (110) rotates, the spiral groove member (140) rotates. When the spiral groove member (140) rotates, the spiral protrusion member (150) rises due to the interaction between the upward spiral protrusion (151a) and the upward spiral groove (141a). When the spiral protrusion member (150) rises, the rotational movement of the spiral protrusion member (150) is restricted by the entanglement between the protrusion member serration (151b) and the container bottom tube serration (123a). When the spiral protrusion member (150) rises, the piston (130) rises along the height direction of the container side portion (121). When the piston (130) rises, the cosmetic stored in the storage space (128) is discharged to the outside through the discharge port
