Abstract
A foamer nozzle assembly has a foaming barrel defining a turbulence chamber for creating foam upon actuation of the trigger of a trigger sprayer as the conical spray impacts against the smooth inner surface of the barrel as so to emerge as loosely compacted, large foam bubbles having a relatively wide foam spread. A foaming grid in the form of an offset rectangular mesh screen is mounted on a hinged panel for movement between operative and inoperative positions. In the former the grid lies coaxial with the discharge orifice and provides a supplemental foam generator for breaking up the foam bubbles into finer and more concentrated foam having a relatively smaller foam spread. The grid comprises first and second sets of ribs lying in first and second parallel planes, the ribs of the first set being contiguous to the ribs of the second set, and the ribs being mutually spaced apart to define uniformly sized openings therebetween. The ribs of both sets have flat surfaces facing upstream and lie perpendicular to the central axis of the barrel.
