ABSTRACT:
A dispensing cartridge, suitable for sealant sausages in use with mechanical and pneumatic sealant applicator guns, comprises a sleeve, a detachable end cap with releasable nozzle and a plunger. The plunger has offsets on its leading and trailing edges, which are the only portions which form a seal with the interior surface of the sleeve. Preferably the support portion of the plunger is bi-concave and the sleeve adapted to receive the end cap on either end. This renders the cartridge bi-directional, allowing loading of sausages and extrusion at either end.
