The bristles of a brush applicator for cosmetics are mounted in a centrally located bushing, which is mounted on radial ribs at the outlet from the barrel. The paste to be applied is forced by a lead screw and piston through the ribs into an ample annular space between a surrounding ferrule and the outside of the bushing. A shoulder on the ferrule compresses the tips of the bushing ribs against the outlet, and its outlet nozzle closely engages the bristles and directs the paste into their tip end. The lead screw is rotated by a knob secured to its rear end, which is snapped into the back end of the casing, to advance an octagon shaped piston through a correspondingly shaped barrel. |
