Abstract
A front cylinder and base are rotatably connected. Relative rotations cause stick-type cosmetic material retained by a core chuck member to slide forward and backward along an axial hole of the cylinder. Axially extending first slide grooves along an inner circumference of the hole have an inside diameter almost equal to a diameter of the material. Second grooves, deeper than the first, extend continuously from ends of the first grooves. Claws at a front-end section of the chuck retain the material and are slidably guided by the grooves. Back surfaces of the claws slide into contact with bottoms of the first grooves. Inner surfaces of the claws almost coincide with an inside diameter of the hole. If the material is loaded in the chuck with the claws at the second grooves, the claws elastically deform outward and the claws receive the material. With the claws at the first grooves, the claws tightly sandwich the material.
