ABSTRACT:
A simplified device for use with dilute soapy water in a container, with the device being adapted to mechanically convert the soapy water together with ambient air into a dense lather. The device comprises a manually operable bladder as a pressurized ambient air source and the only moving part. The device further comprises conduits for movement of air and soapy water, a mixing chamber, specifically sized orifice entries into the mixing chamber for predetermined metered entry of the air and soapy water into the mixing chamber, an elongated porous plug for the mixing chamber and various check valves. In operation, a portion of the pressurized air is directed through a first conduit, to provide air, through a specifically sized orifice, into the mixing chamber. Simultaneously therewith, another portion of the pressurized air is directed through a second conduit into a soapy water reservoir to force a predetermined relative amount of soapy water through a third conduit and a second specifically sized orifice, into forcible engagement with incoming air in the mixing chamber. The resultant foam is forcibly pushed through the porous plug to form lather. A single application of air pressure consistently provides the requisite ratio mixture to the mixing chamber, while drawing additional soapy water into the reservoir. The foam is expressed through a porous nylon sponge element to form the foam.
