Abstract: A foam dispenser having a pump assembly includes a liquid pump, an air pump and a common actuation part to simultaneously actuate the liquid pump and the air pump. The pump assembly includes a dispensing channel having a dispensing opening. The pump assembly further includes a porous matrix which contains a dispensate material.

Abstract: A foam dispensing device uses a single actuator to actuate two concentric pistons, one for an air chamber and one for a telescopically oriented liquid chamber. In all of the various embodiments the liquid chamber stops its actuation first and can continue to move along with the single actuator and the air chamber continues to dispense air. The air and liquids are dispensed into foaming chamber and then dispensed. The liquid chamber can continue to move because the liquid chamber is attached to the pump system by a deformable connector or some form. This arrangement allows for a foaming device that uses just one actuator that has the ability to dispense foam in the first phase and just air to clear out the nozzle effectively in the second phase.
