The foam producing unit includes an inner container 18 of substantial smaller cross section than the outer container 12, and a closure cap having a pressurized air inlet 28 and foam outlet 30. A one-way valve 66 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. <IMAGE> |
