Abstract
A hand-held foaming apparatus includes a pressure vessel for containing a foamable liquid and an air space overlying the liquid. A hand pump is mounted within the vessel and sealably connected to a sealable opening at the top of the vessel. The pump comprises an external handle connected to a piston that extends substantially to the bottom of the vessel. Actuating the pump by operating the handle causes formation of foam from the foamable liquid in the overlying air space and discharge of the foam from a foam discharge outlet that comprises foam discharge control means and an interchangeable nozzle and is located on the vessel above the air space.
