Abstract
The glue gun system includes a gun having a barrel. A cartridge can be removably placed in the barrel. The cartridge has an open central passage to accept a glue slick and a tip to dispense the glue. Once received into the barrel the cartridge is heated, melting the glue therein. Additional cartridges can be maintained in a heated state by a heating stand. Thus, after one glue stick is used, a second can be immediately installed and used. An insulated tab allows for the easy handling of the cartridges.
Claims12
A glue gun system for dispensing glue from sticks, comprising:
- a glue gun having a body with a mating region for accepting a removable cartridge;
- said removable cartridge operable to be removably disposed within said mating region and suitable for accepting a glue stick, and having an insulated member disposed about at least a portion of said removable cartridge for a user to grasp when removing said removable cartridge from said mating region in said body of said glue gun while said removable cartridge is at operating temperatures;
- said removable cartridge when mated with said body allowing melt flow glue to be dispensed at operating temperatures;
- a heating device for heating at least a portion of the glue stick in a cartridge heat zone, said heating device being mounted to said removable cartridge;
- a releasable interface for interfacing said removable cartridge with said body to allow said heating device to heat to said operating temperatures when said removable cartridge is mated with said body in said mating region, wherein said interface is interrupted by the action of removing said removable cartridge from a mating relationship with said body;
- and
- the glue gun providing a glue-stick gripper and a glue-stick advancement means at a first end of said removable cartridge for moving the glue stick through said cartridge heat zone and dispensing melt flow glue from an opening disposed in a second end of said removable cartridge.
The glue gun system of claim l wherein said removable cartridge comprises:
- (c) a tip having an orifice in fluid connection central passage of said removable cartridge;
- and
- (d) a extension from said tip.
A glue gun system for dispensing glue from sticks, comprising:
- a glue gun having a barrel body with a central passage for interiorly receiving a removable cartridge;
- said removable cartridge operable to be removably disposed within said central passage of said barrel body and having an insulated tab disposed about at least a portion of said removable cartridge for a user to grasp when removing said removable cartridge from said barrel body while said removable cartridge is at operating temperatures;
- said removable cartridge suitable for interiorly receiving a glue stick, and having a cartridge heat zone for melting the glue stick therein when said removable cartridge is mated with said body;
- said removable cartridge when mated with said body allowing melt flow glue to be dispensed at operating temperatures;
- a heating device for heating at least an end portion of the glue stick in said cartridge heat zone, said heating device being mounted to said removable cartridge;
- a releasable interface for interfacing said removable cartridge with said barrel body to allow said heating device to heat to said operating temperatures when said removable cartridge is disposed within said barrel body, wherein said interface is interrupted by the action of removing said removable cartridge from said barrel body;
- and
- the glue gun providing a glue-stick gripper and a glue-stick advancement means at a first end of said removable cartridge for moving the glue stick through said cartridge heat zone and dispensing melt flow glue from an opening disposed in a second end of said removable cartridge.
