ABSTRACT:
A cartridge for dispensing a filler stick wherein the stick is advanced automatically out of one end of the cartridge by the removal of the cap. The stick is supported on a piston slidable in the cartridge and vented at the bottom of the cartridge to the atmosphere and the cap and cartridge have a slidable seal such that removal of the cartridge creates a vacuum within the cap to enable the air pressure on the piston to force the stick out of the cartridge.
