PURPOSE: An airtight ring structure of a cosmetic container is provided to uniformly contact the internal surface of the cosmetic container when an external lid is closed, thereby keeping the cosmetic contents air tightly for a long time. CONSTITUTION: An airtight ring structure of a cosmetic container includes a container body(100), an inner container(200), a shoulder(300), an external lid(400), and an internal lid(500). The container body forms a hanging end projection(120) and an assembly groove(130) on an inner surface and an outer surface. The inner container is combined with the container body by a horizontal hanging piece(220), and has a sealing protrusion(230). The shoulder is assembled by a inner bending ring(310), and covers the upper side of the horizontal hanging piece. The external lid is combined with the shoulder by a hinge piece(410). The internal lid comprises a sealing accepting groove(540) and an elastic hanging piece(550). |
