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.
