  • Dispenser for a flowable product
    Patent number: 7374066
    Abstract: A dispenser for a flowable product such as liquid soap is arranged to receive a can containing the liquid soap as well as two different propellants. Gaseous nitrogen under pressure acts as a primary propellant, while propane and/or butane in a liquid phase acts to foam the soap when it is released from the can. An electronically controlled valve is actuated when a sensor detects the presence of a user's hand adjacent an outlet, and a predetermined quantity of foamed soap is then dispensed.
