A hand-held foaming apparatus includes a pressure vessel for containing a foamable liquid and an air space overlying the liquid. A hand pump is mounted within the vessel and sealably connected to a sealable opening at the top of the vessel. The pump comprises an external handle connected to a piston that extends substantially to the bottom of the vessel. Actuating the pump by operating the handle causes formation of foam from the foamable liquid in the overlying air space and discharge of the fo...

The present invention relates to a low cost, article for the delivery of personal care foams comprising a package comprising a container having flexible, deformable walls, an opening portion, a first sponge having a density of from about 1.5 to about 3.0 lbs./ft.sup.3 ; an indentation force deflection of from about 40 to about 65 lbs./50 in.sup.2 ; and a porosity of from about 50 pores per inch to about 100 pores per inch; and a second sponge having a density of from about 1.30 to about 2.00 lbs...

An apparatus for making and dispensing foam has a housing forming a generally closed foaming chamber, a liquid pump for drawing liquid from a supply and spraying the liquid into the foaming chamber, and an air pump for forcing air into the foaming chamber. A conduit forms a continuously open passage having an inner end opening into the foaming chamber and an outer end open to outside. A foam generator in the foaming chamber mixes the spray and air therein to generate foam and expand the foam to ...

A foam dispenser comprises a housing having an opening, a fluid reservoir placed in the opening of the housing, a plug connected to the fluid reservoir in the opening, and a foam pump, comprising an air pump, a fluid pump, a closable supply to the air pump, a nozzle, and a movable operating part, wherein the foam pump dispenses a quantity of foam through the nozzle upon actuation of the operating part in a direction of pumping, wherein the foam pump and the fluid reservoir are combined into a re...

A dispenser for dispensing a soap product includes a soap pump, a dispensing nozzle, and an expandable and contractible suction chamber. The dispensing nozzle has an outlet for dispensing soap, and the suction chamber is disposed between the soap pump and the dispensing nozzle. The suction chamber is expandable and contractible in volume and is predisposed to an expanded volume. Actuation of the soap pump causes the suction chamber to contract to a contracted volume that is less than the expande...

A fluid dispensing assembly comprising a terminal orifice assembly having a terminal orifice aperture or element therein from which fluid from the dispensing container on which the dispensing assembly is mounted, issued, wherein an anti-foaming composition is disposed on the exterior surface of the terminal orifice assembly adjacent and/or contiguous to the terminal orifice so as to immediately engage fluid product issuing from the terminal orifice in order to reduce and/or eliminate any foaming...

This foam dispensing device includes a flexible container for foamable liquid, having a discharge opening at one end. A foam producing assembly is housed within the container, the assembly including a self-supporting porous member of rigid material held within the neck of the container and a tubular member of non-porous material having one end extending into the porous member and the other end extending into the interior of the container. Fluid mixing within the porous member is facilitated by f...

A piston pump for dispensing foam by simultaneously dispensing air and liquid through a foam generator and in which air to be dispensed is drawn into a chamber from which it is to be dispensed, at least in part, through an air inlet passageway which is different than a flow path out which foam is dispensed. A lost link valve arrangement provides for relative motion to open the air inlet passageway when air is drawn into the chamber and to close the air inlet passageway when air is forced out of ...

A manually operated liquid foaming dispenser is attached to a bottle of liquid and pumps and mixes both the liquid and air to create a foam from the liquid and to dispense the foam. The dispenser includes a pump housing containing an air pump chamber and a liquid pump chamber, and a pump plunger that is manually reciprocated in both the air pump chamber and the liquid pump chamber. An air piston and a liquid piston are mounted on the plunger and are reciprocated by the plunger in the respective ...

A manually operated liquid foaming dispenser is attached to the top of a container of liquid and is manually vertically reciprocated to dispense the liquid from the container as a foam. The dispenser includes a liquid pump chamber and an air pump chamber that respectively pump liquid and air under pressure to a discharge passage of the pump where the liquid and air are mixed, generating the foam dispensed from the dispenser. The air pump chamber has a tube valve controlling the discharge of air ...
