发明名称 LOW COST TRIGGER SPRAYER IMPROVEMENT
摘要 A low cost trigger sprayer has a housing with a first liquid passage containing a spinner assembly. A pump element is positioned generally horizontally such that pulling the trigger contracts or retracts the element and releasing the trigger permits the element to return to an extended position. An elastomeric spring is positioned between the housing and pump element to improve the return characteristics of the pump element. 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 upward past the neck and defines a saddle recess with the housing connected to the neck of the container and positioned forward of the upward extending container portion.
