The nozzle assembly comprises a cap and a bushing for mounting to the front of the body of a trigger sprayer in communication with a passage in the trigger sprayer. The cap is mounted to said bushing and is rotatable on the bushing between three positions, they being a stop position, a spray position and a foam position. The nozzle has first passage means and the cap has second passage means. The respective first and second passage means are arranged to communicate with each other in the rotated spray position and in the rotated foam position of the cap. The cap is provided with foam generating means within the cap and in communication with the respective passage means when the cap is rotated to a foam position for generating foam on actuation of a trigger of the trigger sprayer to which the nozzle assembly is mounted.

Nozzle assembly

The two piece foamer nozzle assembly comprises a first piece including a body having a front end and a rear end and a second piece releasably connected to the first piece. The first piece has a first cavity in the body thereof opening onto the rear end thereof and being adapted to be received over a nozzle bushing mounted at the front end of the body of a hand manipulatable pumping apparatus. The nozzle bushing is of the type which will eject fluid into the first cavity in a swirl or spiral manner. The first piece further comprises a barrel portion having a second cavity opening onto the front end thereof and an intermediate wall within the first piece between the first and second cavities. The intermediate wall has an orifice extending therethrough with a rear end communicating thereof with the first cavity and a front end communicating with the second cavity. The swirl of liquid is ejected in a spray pattern from the front end of the orifice. The second piece has a rearwardly extending formation sized to be releasably received and fixed within the second cavity of the first piece. The formation has a foam generating chamber therein which opens onto the rear end of the second piece in front of the front end of the orifice and which has an irregular surface therein. The second piece also has a front end with a nozzle opening therein and the foam generating chamber is in communication with the nozzle opening whereby liquid sprayed in a generally conical pattern into the foam generating chamber and impinging upon the irregular surface mixes with air and creates foam which is ejected through the nozzle opening.
