ABSTRACT OF THE DISCLOSURE The foam nozzle assembly is mounted to a trigger sprayer and comprises an outer barrel portion defining a foam generating chamber into which liquid is ejected in a conical spray from an orifice in a back wall of the foam generating chamber. The cone of the spray subtends a predetermined angle. The nozzle assembly includes a perforated wall which is located in the outer barrel portion and which is spaced forwardly of the orifice from which the conical spray is ejected. The perforated wall has ribs and slots therein and the back edges of the portions of the ribs between slots is rounded to provide a surface upon which the conical spray can impinge and be deflected in different directions to mix with air in the foam generating chamber to create foam. The rounded back edge of each of the ribs is defined by a generally circular round having a given radius R. Preferably, the width of each slot is defined as S, and the radius R is in a ratio to the slot width S, R:S, of between approximately 1:2 and 1:4.
