  • Patent number: 7278554
    Abstract: There is provided a dispensing apparatus having a liquid container located therein which is provided with a valve assembly having a foam pump and an actuator for actuating the foam pump in which the housing includes a cover pivotally attached to a backing plate. The cover is movable from a fully open position in which the container may be inserted therein to a closed position. A housing adaptor is attached to a projection on the interior surface of the cover and engages the actuator. The housing adaptor is configured so that as the cover is moved in a first direction from a non-dispensing position in which no liquid is dispensed from the container to an dispensing position, the actuator moves in a second direction to actuate the foam pump and dispense foam from the container.
