ABSTRACT:
A lip balm or other stick is adapted to be propelled and repelled by a piston slidable in a first end opening of a package tube having a second end opening in which a knob is slidable and rotatable approximately 90 degrees between propel and repel positions. An axial post on the knob is adapted to be connected to the piston by a reversible translatory clutch comprising propel and repel pawls on the piston, spaced apart approximately 90 degrees, and engageable by ratchet teeth and interspersed ratchet notches adapted to be presented to the propel pawls, when the knob is in its propel position, and to the repel pawls, when the knob is turned approximately 90 degrees to its repel position. A spring biases the knob outwardly and is operative to repel the piston after the knob is pushed inwardly when in its repel position. When in its propel position, the ratchet teeth propel the propel pawls when the knob is pushed inwardly. In a second embodiment, the post has friction clutch surfaces of enlarged diameter and adapted to be presented selectively to the propel and repel pawls by turning movement of the knob.
