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. A vertical wall having circumferentially spaced vertically disposed ribs exteriorly thereof is carried by the base and wrench and forms an element of the metering device for regulating the amount of contents to be discharged by upward motion of the piston. A pawl clicker is carried by the dial apron and is positioned to strike the vertical ribs on the vertical wall to cause an audible click and signal discharge of a metered amount of contents.
