ABSTRACT:
Improved dispensing cartridges for use in combination with a dispenser to distribute high viscosity material, such as soap, for example, include an integral but removable bottom wall which serves the dual purpose of acting as the bottom of a container during transportation of the cartridge and acting as a pressure plate in response to atmospheric pressure to assist dispensing of the material when the cartridge is installed on the dispenser and the bottom wall is detached. A modified form of the invention is designed to be utilized selectively with either free running dispensers or with dispensers which include a screw operated pressure plate and includes a centrally disposed removable section in the bottom wall.
