Abstract: The trigger operated dispensing device for mounting to a container comprises: a body made of plastic material and having a pumping chamber therein. The pumping chamber has an open outer end and an inner back wall, a pumping mechanism associated with the body and includes a plastic piston situated in the pumping chamber and a plastic trigger coupled to the body. Non-metal biasing structure is situated between the trigger and the body for biasing the piston out of the pumping chamber. Non-metal fluid inlet structure and non-metal fluid outlet structure are associated with the pumping chamber and comprise first and second plastic flap valves in or adjacent the back wall. Also provided is non-metal structure for coupling the body to the container. The trigger operated dispensing device has only parts made of non-metal or synthetic material therein.

Abstract: The tamper evident trigger sprayer bottle cap/bottle neck assembly comprises: a trigger sprayer including a body and a fluid intake portion, the fluid intake portion having retaining structure protruding laterally outwardly therefrom for retaining an open top bottle cap thereon; a bottle cap comprising a top portion, a cylindrical wall depending from the top portion, and a tamper evident ring depending from the cylindrical wall, the top portion having a central opening therein, the fluid intake portion extending upwardly through the central opening and the cap being supported on the retaining structure; sealing structure associated with the retaining structure and the bottle cap for effecting a seal between them when the bottle cap is mounted on a bottle neck to a fully connected position, the tamper evident ring being frangibly connected to the cylindrical wall by a plurality of spaced apart easily breakable webs or filets molded to and extending between the tamper evident ring and the cylindrical wall of th

Abstract: A trigger operated fluid dispensing device for mounting to a container comprising: a body having a front end including opposed side walls at the front end, a nose bushing extending from the front end between the body side walls and at least one, elongate, nozzle cap blocking member which extends from the body front end and which is adapted to engage and prevent rotation of a nozzle cap upon rotation of the cap without manipulation of the body side walls; a nozzle assembly at the body front end including the nose bushing, a nozzle cap received on the nose busing and cooperating structure on or in the nozzle cap and on or in the nose bushing for selectively establishing an off position, a spray position or a stream position of the nozzle cap upon rotation of the nozzle cap; the nozzle cap being mounted for rotation on the nose bushing between the three positions and the nozzle cap having engaging structure therein positioned adjacent the blocking member for engaging the blocking member when someone attempts to

Abstract: The tamper evident cover assembly is used with a sprayer nozzle of a trigger sprayer of the type including a body, a trigger movably mounted to the body for operating a pumping mechanism upon actuation thereof and a sprayer nozzle at the front end of the body. The tamper evident cover assembly comprises a cover for the nozzle, at least one flange extending rearwardly from the cover and having first coupling structure thereon for coupling to the trigger, a frangible connection between the flange and the cover, and, second coupling structure on the trigger for coupling with the first coupling structure upon the flange, whereby actuation of the trigger will cause the cover to be pulled against the nozzle to cause tensioning and breaking of the frangible connection between the flange and the cover and separation of the cover from the sprayer nozzle, such resulting separation being evidence of tampering with the trigger sprayer.

Abstract: The trigger operated fluid dispensing device is adapted to be mounted to a container. The device comprises a body having a top wall portion and front end portion. A nozzle assembly is provided at the front of the body and comprises a nose bushing at the front end of the body and a nozzle cap rotatably mounted to the nose bushing. The nozzle cap has blocking structure that is engageable with structure that prevents rotation of the nozzle cap. A pull-away piece is detachably connected to the top wall portion of the body and has extending structure extending into the area between the nozzle cap and the front end of the body for engaging the blocking structure for preventing relative movement between the nozzle cap and the body.
