  • Patent number: 9718069
    Abstract: The present disclosure relates to a non-aerosol foam pump for use in association with an unpressurized liquid container and a foaming element comprising. The pump includes a liquid pump portion and an air pump portion. The liquid pump portion has a liquid chamber with a liquid internal volume and a shuttle liquid piston. The liquid chamber is in flow communication with the unpressurized liquid container and in flow communication with the foaming element. The air pump portion has an air chamber with an air internal volume. The air chamber is in flow communication with the foaming element. The liquid pump portion and the air pump portion have an activation stroke and a return stroke. During the activation stroke the air internal volume is reduced and during a beginning stage of the stroke the liquid internal volume remains the same and during a later stage the liquid internal volume is reduced.

  • Patent number: 9073066
    Abstract: A foam assembly connectable to a liquid container includes a main pump body, a resiliently deformable piston dome, an air chamber, a liquid chamber, a mixing zone and a porous member. The main pump body has an exit nozzle with the porous member therein. The air chamber and the liquid chamber are each defined by the piston dome and the main pump body. The liquid chamber has a liquid inlet valve and a liquid outlet valve. The mixing zone is in flow communication with the air chamber and the liquid chamber. The volume of the air chamber and the liquid chamber are each dependent on the position of piston dome and during an activation stroke the piston moves from the at rest position to the depressed position and responsively the volume of the air chamber and the volume of the liquid chamber are reduced.

  • Publication number: 20020153389
    Abstract: A foam dispenser includes a resiliently deformable bottle which has an interior, a neck at one end thereof and an opposed end. The bottle has an at rest position and an under pressure position. A mixing chamber is proximate to the neck and has a soap inlet and an air inlet both upstream of an outlet. The outlet has a porous material thereover. The interior of the bottle is in flow communication with the mixing chamber through the soap inlet. An air tube extends from the mixing chamber into the interior of the bottle and has a distal end proximate to the opposed end of the bottle whereby the mixing chamber is also in flow communication with the interior of the bottle through the air tube. A self sealing pressure actuated valve is for selectively opening and closing the outlet and is responsive to pressure applied to the bottle.
