A cosmetic preparation dispenser permits filling of a dispenser cartridge and retraction thereof, but is subsequently inoperable until assembly with a master case. The cartridge includes a cam sleeve, innerbody and elevator cup. The locking of the cartridge is obtained by lower leftwardly extending track segments at the lower end of innerbody longitudinal track segments, which trap and retain the elevator cup when it is retracted after the cartridge is filled with a cosmetic stick. When the cartridge is assembled with the master base, a stem in the master base pushes against the elevator cup to urge it out of it locked position to permit the elevator cup to be freely movable along the axial path.
