Abstract: A dispenser for soap, shampoo, tooth paste, etc. has a housing with a removable cover for the reception of disposable refill cartridges. A plunger within the dispenser is caused to advance axially by a rack and pinion mechanism to dispense the contents of the refill cartridge from an opening in the bottom of the housing. Both the plunger and a door covering the dispensing opening are actuated by manipulation of a single knob. The housing is provided with mounting bosses for securing the dispenser on a wall with conventional threaded fasteners.
