  • Patent number: 4828419
    Abstract: A cosmetic applicator of the type comprising a longitudinally elongated cap that contains a cosmetic cake, a longitudinally elongated barrel holder with a first end supporting a resilient applicator is improved by a longitudinally elongated godet that encloses the cosmetic cake and presents only a substantially transverse exposed surface for contact with said applicator, and an applicator tip that is resilient and expands transversely into a substantial wiping contact with the godet interior wall upon compression against the exposed cake surface. The invention further is characterized by a mounting to rotatably and removably mount the cap upon the barrel at a substantially fixed longitudinal mounting position, and resiliently to maintain a substantially constant pressure during contact between the applicator and the exposed cosmetic surface as the barrel and cap longitudinally are moved into and out of the fixed mounting position.
