Abstract
This invention relates to pump-action nozzle devices methods of making the same. The nozzle devices of the invention comprises a body which defines an internal chamber having an inlet through which fluid may be drawn into said chamber and an outlet through which fluid present in the chamber may be expelled from the nozzle. The inlet comprises an inlet valve and the outlet comprises an outlet valve. Fluid is dispensed from the dispenser nozzles by applying pressure to an actuator member that engages and resiliently deforms or displaces a portion of the body of the device that defines the chamber, thereby compressing the chamber and actuating the dispensing of fluid. In preferred embodiments, the actuator provides a rigid actuator surface that an operator can apply a pressure to.
