  • Removable cartridges for a glue gun system
    Patent number: 5769272
    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 stick 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.
