ABSTRACT:
The present invention relates to a dispenser for flowable material having a container with open and closed ends and a dispensing head with a product outlet mounted on the open end of the container. The flowable material, stored within the chamber defined by the container, is forced by a piston downwardly through the chamber and then upwardly through a hollow rod on which the piston is mounted, a tube extending from the dispensing head, and the product outlet. The threaded rod terminates at a cup which receives and is sealed by sealing surfaces of the tube, thereby providing a fluid coupling from the container to the dispensing head.
