DISPENSING APPARATUS

摘要

The apparatus comprises a cartridge holder and main body having a generally circular central portion (17) with three perpendicular flanges (3, 4, 5) extending from one side and an elongate portion (6) extending from the other side. A known drive means (not shown) on the elongate portion mounts a drive rod U-shaped (12) for axial movement. Each flange includes a slot (5) for receiving a pin formed on a replaceable generally cylindrical cartridge to act as a bayonet fitting. Viscous material is expelled from the held cartridge by driving the rod (12) axially. A nozzle attachment has a primary section connected to the exit of the cartridge and includes a secondary section for holding a replaceable hardener tube, the hardener being expelled by axial movement of the portion (14) of the rod (12). The nozzle attachment includes a planar end surface for simple cleaning.
