Abstract
A device for dispensing molten thermoplastic material which an operator grips while using his thumb to press a solid block of the thermoplastic material through a sleeve and into a heated melting chamber from which the molten thermoplastic material is discharged through a nozzle. The device includes a bracket adapted to hold a second block of thermoplastic material in end-to-end relationship with a first block in the sleeve, and a heated barrier ring at the inlet to the melting chamber that restricts escape of the molten thermoplastic material through the sleeve; and may also include a slidable pressure plate between the block and an operator's thumb and/or a trigger-operated outlet valve between the melting chamber and nozzle.
