Dispensing cartridge refilling system

摘要

A dispenser refilling system (20) includes a bulk container (30) for refilling a cartridge (88) of a dispenser, so that the cartridge need not be disposed of after a single use. The system preferably includes one or more fill tubes (78) that are movable by lever operation for extension into the chamber of the cartridge when desired. Each fill tube couples to a piston in the cartridge and directs the component to be replenished in the cartridge chamber through a port in the piston. In certain embodiments, the system includes two bulk containers and a dual chamber dispensing cartridge, and structure is provided to prevent inadvertently reversing the position of the cartridge and for insuring placement of the containers in proper receptacles. $$
