  • Patent number: 4595124
    Abstract: The present disclosure is directed to a container for dispensing semi-solid products consisting of a cylindrical body having a rounded closed applicator end and an opposite open ended base. A dome shaped product discharge piston is movable through the body beneath the storage chamber driven by a piston drive screw having two flat and two arcuate sides opposed each other for driving the piston upwardly in the cylindrical body to discharge the product. A dial and screw drive ratchet is positioned within said container and has a manually rotatable apron for advancing the screw shaft and piston and is positioned beneath said piston. A base and wrench is positioned at the open end of the container for positioning and supporting the dial and screw drive ratchet to permit the drive screw to be rotated by the dial apron while permitting axial motion of the drive screw through the base and wrench to drive the piston upwardly.

  • Patent number: 4359292
    Abstract: A cosmetic dispenser is disclosed which include a socket having a dispensing opening and three orthogonal axes, one axis extending through the socket and the other two lying substantially in the plane thereof. An applicator member is retained in the socket and has an upper portion extending exteriorly of the dispensing opening and a skirt portion substantially retained within the socket. The applicator is adapted for rotation about the three axes, but stop means limit rotation of the applicator member about the two axes in the plane of the socket. In this manner when rotation occurs about the axes of limited rotation, the dispenser is operable to feed cosmetic across the skirt portion to the upper portion of the applicator member for application to a surface to be treated with the cosmetic.

    Abstract: A roller-type cosmetic applicator is described featuring a cap of T-configuration adapted to fit on the outlet of a product container. The head portion of the cap has an integral cylindrical bearing element through which extends an axle having two rollers affixed at opposite ends. The axle has a reduced central portion defining a chamber between the axle and the bearing element. The chamber is in communication with the container, and, through two small openings, with the uppermost portion of the cap, where the product is delivered for distribution by the rollers. In one embodiment the reduced portion of the axle is provided with vanes comprising an impeller, which when rotated with the rollers and axle, assist dispensing of the product.
