ABSTRACT:
A dispenser unit includes a container formed from a tubular member having a constant transverse cross-sectional configuration which is adapted to contain an extrudable material. One end of the tube is closed by an end wall having a discharge nozzle therein which can be selectively sealed by a closure cap. The other end of the tubular member is sealed by an air-tight end wall. Disposed within the tubular member is a compression arrangement which includes a threaded shaft adapted for rotational non-longitudinal motion within the tubular member and a compression element mounted on the shaft and adapted for longitudinal motion within the tubular member when the threaded shaft rotates to exert an expelling or compression force on the extrudable material. An operating structure adapted for longitudinal non-rotational reciprocating motion on a support associated with the container has an idle position and an actuated position, and is constantly urged to its idle position. A kinematic translating train in operative engagement with the operating structure and the compression arrangement converts the longitudinal non-rotational motion of the operating structure from its idle position to its actuated position to rotational motion of the shaft and permits the operating structure to return to its idle position without rotational motion of the shaft.
