Lather device
First Claim
1. A device for use with dilute soapy water contained in a container, whereby said device mechanically converts a mixture of the soapy water and pressurized ambient air into a dense lather, wherein said device comprises a source for pressurized ambient air, a reservoir as a direct source for the soapy water to be converted to lather, a mixing chamber for admixture of the soapy water and the pressurized ambient air and the formation of a foam therein, a lather formation chamber containing a porous member for converting foam to lather by forced passage of the foam therethrough;
- said device further comprising first conduit means providing a direct air connection between the source for pressurized ambient air and the mixing chamber;
second conduit means providing a direct air connection between the source for pressurized ambient air and the reservoir;
third conduit means providing a connection for flow of soapy water from the reservoir to the mixing chamber;
measured metering means between the mixing chamber and each of the first and third conduit means respectively whereby a fixed ratio of compressed air to soapy water is maintained in said mixing chamber; and
porous means capable of converting foam to lather by the forced expressing of foam therethrough.

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.
