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.
