Abstract
A dispenser for dispensing a soap product includes a soap pump, a dispensing nozzle, and an expandable and contractible suction chamber. The dispensing nozzle has an outlet for dispensing soap, and the suction chamber is disposed between the soap pump and the dispensing nozzle. The suction chamber is expandable and contractible in volume and is predisposed to an expanded volume. Actuation of the soap pump causes the suction chamber to contract to a contracted volume that is less than the expanded volume to which it is predisposed, and soap is forced through the suction chamber and the dispensing nozzle to the outlet where it is dispensed. Soap that has not been dispensed at the outlet resides in the dispensing nozzle after actuation of the soap pump, and this residual soap is sucked back into the suction chamber during a return of the suction chamber to the expanded volume to which it is predisposed.
