Abstract: A hot glue gun having a no-drip tip 20 comprised of a self-closing tip once the trigger 24 mechanism is disengaged which incorporates a mechanism for advancing 24 the glue cartridge 22 forward which opens the self-closing tip 30, a mechanism for retracting 44 the glue cartridge once the trigger is released and a mechanism for closing 46 the self-closing tip as the glue cartridge is retracted thereby preventing further glue 26 discharge. Apparatus 10 incorporates an interiorly disposed cone shaped tip 20 having a tensioning mechanism 46 keeping the tip halves 54 closed until a predetermined pressure is applied to the trigger 24 whereupon the glue cartridge 22 is advanced forcing the interior tip halves 54 to diverge allowing passage of the adhesive. Once pressure is removed from the trigger 24 a spring 44 abutting the glue canister cartridge 22 and the back end of the self-closing tip moves the cartridge to a tip disengaged position thereby providing for the tip tensioning members to close the no-drip tip 20.
