Abstract
A stick type cosmetic material feeding container which houses a stick type cosmetic material in such a manner that the stick type cosmetic material can be fed out prevents a spiral engagement mechanism from breaking at the uppermost limit or the like. The stick type cosmetic material feeding container further eliminates unsteadiness of the spiral engagement mechanism and can obtain the stress of slide due to the spiral engagement mechanism. A front cylinder having a tip opening hole through which a stick type cosmetic material advances and retreats is rotatably connected with a container body . A core chuck member having a spiral section is inserted in the container body and a rotation regulating mechanism for synchronously rotating the front cylinder and the core chuck member is provided. Further, an elastic engagement section is provided in a through hole of an elastic cylindrical body which rotates synchronously with the container body . Also, it is arranged such that a diameter of the engagement section is smaller than an outside diameter of a rod of the core chuck member and the engagement section constitutes a spiral engagement mechanism together with the spiral section provided on the rod . Thus, when an overload is imposed on the spiral engagement mechanism at the uppermost limit or the like, the engagement section is deformed, thereby preventing the spiral engagement mechanism from breaking which may occur resulting from the overload.
