Abstract
The invention contemplates sealed lead-screw propulsion mechanism for the piston of a container for stick deodorant or the like substance, wherein the container must be filled by hot melted substance which becomes the stick after it has been allowed to cool. The seal is operative when the piston is in its lower-most position within the container, so that liquid (melted) substance cannot seep through the region of lead-screw engagement to the piston. Once the substance has solidified, there is no further need for the seal, beyond retention of aromatic ingredients, i.e., until the product has reached the ultimate consumer; and the seal is operable only upon first dispensing use of the container.
