Abstract:
A hot melt glue gun for receiving a solid glue stick, heating the glue stick to its melting point, and dispensing the melted glue, said hot melt glue gun comprising:a housing comprising a grip portion and a dispensing nozzle; a heating chamber defined in the housing for heating a solid glue stick to its melting point; means for heating the heating chamber; means for feeding the solid glue stick into the heating chamber; a sleeve for holding a portion of the solid glue stick outside the heating chamber; and insulating means in the form of a cylindrical member engaged in the sleeve, with the solid glue stick extending through the sleeve and the cylindrical member and entering the heating chamber, with the insulating means prohibiting heat transfer from the heating chamber to the sleeve to keep the sleeve at a temperature below the melting point of the solid glue stick, thereby preventing melting of the portion of the solid glue stick outside the heating chamber.
