Abstract
Embodiments include reusable stick deodorant containers and associated inserts. The container includes a rotatable detachable base that allows an empty insert to be removed and replaced with a full insert. Each insert includes a screw and a follower that engages the screw. The screw engages the detachable base following insertion into the container, so that rotating the base causes the screw to rotate, moving the follower through the insert and expelling the end of a deodorant stick that is disposed upon the follower.
