Low cost trigger sprayer having spinner with integral elastomeric check and primary valves

摘要

A trigger sprayer (10) has a housing (12) with a first liquid passage (34) containing a spinner assembly (22). An elastomeric pump element (16) is positioned generally horizontally such that pulling the trigger (14) retracts the element (16) and releasing the trigger (14) allows the element (16) to extend. The sprayer (10) includes a spinner assembly (22) and valving to control the flow of liquid within the sprayer (10). In one aspect of the invention, the housing (12) has front and rear sections with the rear section having a saddle portion and being hinged to the front section for pivotal movement from an open position for molding the housing to a closed position for operating the sprayer (10). In another aspect of the invention, the container (28) has a rear portion (202) which extends upwardly past the neck and defining a saddle recess (214), with the housing (12) connected to the neck of the container (28) and positioned forwardly of the upwardly extending container portion. The sprayer (10) may include an elastomeric spring for biasing the pump element in the extended position.
