ABSTRACT:
A foaming device for generating and dispensing foams formed by mixing air or other gas with a foamable liquid having a high solids content under pressures of a magnitude on the order of pressures developed by manual collapse of an elastomeric bottle. The device includes a continuous passageway extending from a point of submergence in liquid to be foamed through the gas to be mixed with the liquid to a discharge opening, that portion of the passageway located in the gas being formed of a porous tube by which gas under pressure will be introduced to liquid passing upwardly through the passageway under the same pressure and mixed therewith. A flow restriction in the form of a static mixer is located in the passageway at a point to be coextensive with or elevated above the level of the porous tube.
