  • Patent number: 5505041
    Abstract: A deodorant/antiperspirant solid stick form product, formed and extruded from a mold having a cavity in the shape of the desired stick and within said cavity a threaded shaft axially oriented therein and rotably mounted at the bottom side through an aperture. An elevator platform is threadably mounted to the base of the threaded shaft. Chemical product is then poured into the mold in its liquid or molten state. Upon cooling, the product solidifies and takes on the shape of the cavity of the mold. Reverse rotation of the threaded shaft advances the elevator platform and its now attached stick out of the mold and into a thin walled recyclable refill package. The body of the package is in the shape of the stick, one end is closed and has a sealed vent aperture, the other end is open, broadened and sealed. An empty dispenser (now with its used up stick elevator platform removed and discarded) is coupled to the refill containers open broadened end in a close fitting engagement.
