Abstract:
A hand-held apparatus for spraying foam comprises (a) a manually-operated dispensing pump capable of receiving a foamable liquid from a suitable container and ejecting it into the atmosphere through an atomizing nozzle, thereby forming a spray from such liquid and projecting it outwardly from the nozzle in a predetermined spray pattern, and (b) foam-forming device including an air inlet and a screen retained in the path of the spray. The screen can be retained in a foam-forming position by suitable means such as a housing operatively associated with the dispensing pump. Substantially all the spray passes through the foam-forming device without contact except by the screen, thereby generating foam with little modification of the predetermined spray pattern.
