Abstract

See full text

A cosmetic pencil is provided in which the color tone of its cosmetic material may be distinguished from the outside without marking a cylindrical shaft or a tail cap thereof with the same color, and does not require a secondary processing such as cutting processing for preventing a movement of the cosmetic material when the cylindrical shaft is formed. A transparent cylindrical shaft (2) having a good cutting property is formed from a composite material of olefin-based polymer with polypropylene as the base material, a softened cosmetic material (M) is filled and set in a shaft hole (22) of this cylindrical shaft (2), and the tip end side of the cylindrical shaft (2) is cut to use the cosmetic material (M). The transparent cylindrical shaft (2) has moving prevention measure (5) for the cosmetic material (M) to prevent the filled cosmetic material (M) from moving within the shaft hole (22), and this moving prevention measure (5) may be molded by an injection molding method.
