Abstract
An apparatus for dispensing a post-foaming gel soap is disclosed. The dispenser includes a housing containing a first actuator and a second actuator. A motor is operatively connected to said first and second actuator. A circuit is connected to said motor, as well as a sensor assembly and a power supply. In operation, said first and second actuator moves a stem valve and a cylindrical pump located on a reservoir containing a gel soap and an inert propellant gas. The cylindrical pump operates on a piston principle and also closes to prevent any dripping after use. Further disclosed are various methods of accurately dispensing a consistent dose of gel soap.
