摘要： 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.

摘要： A trigger sprayer pump for dispensing a fluid from a container includes a body (12) containing a pumping chamber (46) having an inlet (56) and an outlet conduit (62). A piston (18) is reciprocably mounted in the pumping chamber (46), the piston (18) having a convexly contoured outer end surface (104). A trigger (16) pivotally mounted and locked to the body (12) has a plurality of triangular supports (100) co-joined to form a tapered socket (102) receiving the outer end surface (104) of the piston (18). A channel-defining insert (24) is received in the outlet conduit (60), the insert (24) having a centrally situated, forwardly facing, fixed surface (175,176). The fixed surface can be concave. (176) or a convex (175) protuberance. An elastic, cup-chaped member (26) secured at its periphery (162) to the body (12) has a central aperture (150) situated in contact with and closed by the fixed surface (175,176). The central aperture (150) of the cup-chaped member (26) is a cavity in the center of the interior surface of the member extending only partway through the member, at least two depressions (154, 156) on the exterior surface (158) of the member spaced'from each other yet each intersecting the cavity (150), and a swirl chamber (166) situated between and connected to the depressions (154, 156). The top (14) of the pump (10) is mechanically secured to the outside of the outlet conduit (61) by tabs (81) straddling and locking to the conduit (61).
