Abstract
A cosmetic applicator includes a hollow tubular insert axially mounted in a hollow tubular body member for joint rotational movement. The forward end of the insert has at least one longitudinal slit which permits the insert to be in an open condition. A piston is axially mounted in the insert. The piston has a threaded outer surface disposed for threaded engagement with a threaded inner surface of the forward end of the insert. The threaded surfaces are brought into engagement with each other by mounting a cosmetic containing cartridge in between the forward end of the insert and the forward end of the body member until the cosmetic is received in a cup at the forward end of the piston. The components are dimensioned to form a plurality of seals at spaced locations on the inner surface of the cartridge.
