ABSTRACT:
This foam dispensing device includes an outer container for holding foamable liquid, and a foam producing unit mounted in the discharge port of the outer container. The foam producing unit includes an inner container of substantial smaller cross section than the outer container, and a closure cap having a pressurized air inlet and foam outlet. A one-way valve is provided between the inner and outer containers which opens to replenish the foamable liquid supply in the inner container but remains closed during the foam forming process.
