ABSTRACT:
The present invention relates to a dispenser of the propel/repel type, typically used for solid stick deodorants. The dispenser includes a container, a piston mounted on a threaded rod, and an actuating wheel to rotate the rod and either advance the piston toward a product outlet or retracted it away from the outlet. Filling with molten deodorant material can be effected either through the top (i.e., the product outlet) or the bottom of the dispenser. When top-filling, the container is filled through the product outlet, while the piston is fully retracted. Alternatively, the container can be bottom-filled with a cover over the product outlet simply by advancing the piston slightly toward the product outlet, injecting molten deodorant material through openings in the piston and container, and fully retracting the piston to close the filling openings. Once filled by either technique, the dispenser contents are allowed to cool and solidify.
