Abstract
A sprayer device with a trigger operated pump is operative for pumping and spraying liquid from an attached liquid container. The sprayer device includes an integrally molded valve body provided with a base portion that is configured to be mounted to the neck of the liquid container and a delivery nozzle from which the liquid is sprayed. A pumping chamber in the valve body is in fluid communication with an inside of the fluid container and is further in fluid communication with the delivery nozzle. The valve body is further provided with a head portion that has a filling passage extending between the head portion and the base portion such that a liquid received in the head portion flows through the valve body, around the pumping chamber and exits the base portion into the mounted liquid container.
