  • Patent number: 3954206
    Abstract: A hand held applicator for extruding molten thermoplastic material wherein a supply of the material is contained within an attached receptacle, which receptacle is provided with means for melting a portion of the material contained therein. The melted material within the receptacle is drawn under reduced pressure into a passageway extending through a heated member, and is extruded under increased pressure from a valve controlled orifice provided on one end of the passageway by means of either a motor driven conveyor screw or an electromechanical solenoid actuated piston. Heat for melting the plastic material is conducted from the heated member to the inside of the receptacle by means of a metallic duct member which communicatively connects the inside base region of the receptacle to the passageway. Melting of the plastic material is confined to the base region of the receptacle by thermally insulating the walls of the receptacle from the heated inner base region.
