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 10 having a tip opening hole 11 through which a stick type cosmetic material advances and retreats is rotatably connected with a container body 3. A core chuck member 30 having a spiral section 34 is inserted in the container body 3 and a rotation regulating mechanism for synchronously rotating the front cylinder 10 and the core chuck member 30 is provided. Further, an elastic engagement section 68 is provided in a through hole 61 of an elastic cylindrical body 60 which rotates synchronously with the container body 3. Also, it is arranged such that a diameter of the engagement section 68 is smaller than an outside diameter of a rod 32 of the core chuck member 30 and the engagement section 68 constitutes a spiral engagement mechanism together with the spiral section 34 provided on the rod 32. Thus, when an overload is imposed on the spiral engagement mechanism at the uppermost limit or the like, the engagement section 68 is deformed, thereby preventing the spiral engagement mechanism from breaking which may occur resulting from the overload.
