ABSTRACT:
An improved cosmetic applicator is described in which an inner tubular member has cam slots to guide lugs on a carrier. The carrier supports a cosmetic substance such as lipstick and is moved between retracted and exposed positions by the action of helical grooves in an outer tubular member. A cam slot in the inner tubular member is provided with elongate resilient and flexible elements located to restrict the passage of the carrier lugs into and out of off-sets that provide axial carrier locking positions. The lugs can be moved past the elements which flex in a manner that retains an even swivel torque. A rib is mounted on the inner tubular member so as to contact the carrier and impart an even drag thereto.
