ABSTRACT:
A dispensing device includes a frame designed to receive and support a cartridge containing a viscous product. The dispensing device has a plunger with a plunger shaft and plate for dispensing the viscous product from the cartridge, and a drive assembly with a handle and a trigger for advancing the plunger. The frame of the dispensing device has a front yoke to receive and align the nozzle at one end of the cartridge, and sidewalls defining an aperture designed to receive the cartridge and support the body of the cartridge. A cartridge biasing assembly integral with the frame biases the cartridge toward the front yoke of the frame. The cartridge biasing assembly includes a biasing plate and a spring at least partially surrounded by a shroud. The cartridge is received within an entrance opening in the shroud and is spring-biased forwardly in the dispensing device by the biasing plate to prevent the cartridge from becoming misaligned.
