ABSTRACT:
A warming tray and removable heating cartridges of a glue gun system are provided. The warming tray has a base and a heating stand mounted to the base for holding the cartridges. The warming tray includes leads for connecting the cartridges to a source of electricity for heating the cartridges to operating temperatures. 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 placed in the warming tray such that they are electrically connected to a power supply and heated to a heated state. 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.
