Cosmetic stick with replaceable cartridge - has plastic sleeve, spiral spring, housing, with annular collar, threaded spindle and ridges and grooves

摘要

It has a replaceable cartridge (1) containing the stick (5), the inner end of which is fixed in a plastic screw (7). A spiral spring (10) grips round the stick or plastic sleeve, and rests on the cartridge housing's (2) end inner annular collar and on the plastic sleeve's annular collar (9). A threaded spindle's front end grips the stick's or sleeve's back and is held by an internally threaded sleeve fitting into a housing-part resting on the cartridge by ridges (23,18) or grooves (22). The threaded spindle has outer lengthwise ridges fitting into the cartridge's star-shaped cavity (19), and is enclosed by a spiral spring. ADVANTAGE - The re-useable parts of the easily produced and handled cosmetic stick are kept to a minimum.
