Stick-shaped material propelling container
摘要:
In a stick-shaped material propelling container capable of propelling and retracting a stick-shaped material, the influence of variation of the dimension of the stick-shaped material can be made small. An inner barrel is slidably inserted in an outer barrel, an elastic body which urges the inner barrel rearward is provided between the inner barrel and the outer barrel, a chuck piece which holds a stick-shaped material is provided at a tip end portion of the inner barrel, and a chuck ring is inserted between the chuck piece and the outer barrel. A cross section of the stick-shaped material forms a triangular shape, the frictional force applying part which is in contact with the stick-shaped material to apply a frictional force is formed on an inner peripheral surface of the outer barrel, and the frictional force applying part abuts on a side in the vicinity of a vertex of the stick-shaped material in a cross section of the stick-shaped material.
