ABSTRACT:
The plastic dispenser is of the nature of a caulking gun and it includes a frame having two end members for receiving a caulking cylinder or similar unit therein, a drive screw operatively engaging with one of the end members, and a handle member secured to the drive screw at a portion thereof externally of the frame. This screw has two longitudinally spaced sections of reduced areas, and the engagement between the screw and one end member is such as to permit this screw to be released from or engaged with the one end member when either longitudinal section of reduced thickness is operatively associated therewith to facilitate rapid axial movement of the screw when desired.
