ABSTRACT:
A low cost trigger sprayer has a housing with a first liquid passage containing a spinner assembly. An elastomeric pump element is positioned generally horizontally such that pulling the trigger retracts the element and releasing the trigger allows the element to extend. The sprayer includes a low cost spinner assembly and low cost valving to control the flow of liquid within the sprayer. In one aspect of the invention, the housing 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. In another aspect of the invention, the container has a rear portion which extends upwardly past the neck and defining a saddle recess, with the housing connected to the neck of the container and positioned forwardly of the upwardly extending container portion. The sprayer may include an elastomeric spring for biasing the pump element in the extended position.
