ABSTRACT:
A plastic material squeeze tube dispenser comprising an elongated conical housing having an opening at one end through which is passed in a sealed manner the nozzle end of a squeeze tube containing a plastic material to be dispensed therefrom. A handle body is attached to the housing and includes a trigger actuatable valve means whereby gas under pressure from a source connected to the handle body may be admitted into the housing to apply pressure to the squeeze tube. Upon release of the trigger, the gas then in the housing is vented to the atmosphere to reduce the pressure within the housing to the ambient level. The valve means is constructed so that when operated, no gas from the pressure source can escape directly through the vent, but only after it has been utilized within the housing.
