A cosmetic pencil capable of advancing a soft cosmetic mass a short predetermined distance. The pencil has a lower barrel which includes a gripping disk stop. A hollow sheath member is held in the lower barrel and has an outwardly facing cam surface. A holding tube is rotatably inserted into the lower barrel and surrounds the sheath member. The holding tube also has a cam surface, and a spring member and gripping disk surround a push rod which extends into the center portion of the sheath which holds the soft cosmetic mass. Turning the holding tube forces the sheath inwardly, and the gripping disk holds the push rod steady with respect to the lower barrel and, thus, a small amount of cosmetic mass is moved upwardly by the movement of the sheath with respect to the push rod.

A cosmetic pencil capable of advancing a soft cosmetic mass a short, predetermined distance, said pencil comprising: a lower barrel having a central axis and said lower barrel having a hollow center with an interior surface and having a gripping disk stop member extending from the interior surface thereof; a hollow sheath member having an inner end and an outer end and having an inner cylindrical opening including an inner end and an outer surface, said sheath member being held within said lower barrel to permit the rotation of the sheath member within the lower barrel, said sheath member extending outwardly from the lower barrel, said sheath member and said lower barrel including means to limit the rotation between the lower barrel and the sheath member, and said sheath member including an outwardly facing cam surface located around its outer surface; a spring element positioned between said lower barrel and said sheath member urging said sheath member outwardly with respect to said lower barrel; a hollow holding tube having an inner surface and an outer surface rotatably held in said lower barrel between said lower barrel and said sheath member and said holding tube having an inwardly facing cam surface adjacent said outwardly facing cam surface of said sheath member; a push rod having a cylindrical exterior surface held axially within said lower barrel and extending into close contact with the inner cylindrical opening of said sheath member and movable into said cylindrical opening; a cosmetic mass held within said inner cylindrical opening of said sheath member and extrudable therefrom by the insertion of the push rod into said opening; and a gripping disk having a central opening slightly larger than the exterior surface of said push rod and an exterior surface that fits within said interior surface of said lower barrel and abuts the gripping disk stop member of the lower barrel, said gripping disk also abutting said spring element, which spring element urges said gripping disk against said gripping disk stop, whereby when said holding tube is rotated with respect to said lower barrel and sheath member, the inwardly facing cam surface of the holding tube moves the outwardly facing cam surface of the sheath member and the sheath member itself inwardly with respect to the lower barrel, forcing the gripping disk against the gripping disk stop causing it to bind against the push rod and hold it steady against the inwardly moving sheath member thereby forcing a small amount of the cosmetic mass outwardly from the sheath member, and when the holding tube is further turned, the cam surface moves into a position permitting the spring element to push the sheath member outwardly positioning it for a later cycle.
