Abstract
A noncontainer pressurizing pump sprayer includes a body, which defines a chamber. A piston is positioned within the container and is coupled to a shaft. The piston divides the chamber into an upper section and a lower section. An inlet valve is positioned on the body and permits flow of fluid into the lower section but restricts flow out of the lower section. The shaft of the piston is coupled to a handle. A spray nozzle includes an actuator that is coupled to a control valve and a discharge outlet that is in fluid communication with the lower section of the chamber. In one embodiment, a tube extends continuously from a point upstream of the control valve to a point downstream of the control valve. In another embodiment, a tube is coupled to the piston and extends through the handle. In another embodiment, the tube extends continuously from the spray nozzle and is coupled to the piston.
