ABSTRACT:
The glue dispenser comprises a collapsible tube having an externally threaded spout. A nozzle assembly comprises an internal nozzle threaded onto the spout and a external nozzle mounted on the internal nozzle. A nozzle valve registers with the opening of the external nozzle and is biased into closing engagement therewith by a deformable portion of the valve being urged against a cam surface. A piercing element is formed on the internal nozzle element, and when the nozzle is completely threaded down on the threads of the spout of the collapsible tube, the piercing element penetrates the sealing diaphragm of the spout so that the material in the collapsible tube can be squeezed through the spout and through the nozzle, with the nozzle valve controlling the flow of the material from the dispenser.
