ABSTRACT:
A cosmetic container having a coil-spring shaped holding portion, which is provided at the front end of a push rod, for holding a stick type cosmetic material. The rear end of a stick type cosmetic material is inserted into the center hollow-portion of the coil-spring holding portion. Ribs are optionally provided on the inner surface of the coil-spring holding portion for biting into a stick type cosmetic material to more securely hold the stick type cosmetic material. Even without these ribs, the spring-type holding portion holds a stick type cosmetic material elastically tight by making the inner diameter of the coil-spring smaller, because the coil-spring shaped holding portion holds a stick type cosmetic material elastically. If pressure is applied to a held stick type cosmetic material from the side, the coil-spring shaped holding portion bends and prevents damage to the held stick type cosmetic material. If an axial force is applied to a stick type cosmetic material to extract it from the container, for example if the container is dropped, the spring portion of the coil-spring holding portion will axially stretch to resiliently or elastically hold the stick type cosmetic material to prevent it from being damaged and/or extracted from the container.
