  • Nozzle assembly for trigger sprayer
    Patent number: 5368234
    Abstract: A nozzle assembly for a trigger sprayer having a cap rotatable relative to a housing to establish the spray character of the fluid discharged and a slot and cam follower connection between the trigger sprayer housing and the cap with the cam shaped to impart an "off" condition, a gradually increasing spray condition, a combination spray and stream condition of gradually reversed relative influence, and a stream only condition. The different flow conditions are established by the interrelationship between a spinner head section and the cap that is rotatable along a path controlled by the cam and cam follower.
