<p>This invention relates to pump-action nozzle devices and methods of making the same. The dispenser nozzles of the invention comprises a body which defines an internal chamber having an inlet (108) 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 pulling the trigger handle (401) of a trigger actuator (400) to resiliently deform or displace a portion (102b)of the body of the device that defines the chamber, thereby compressing the chamber and actuating the dispensing of fluid. In preferred embodiments, the outlet comprises an outlet passageway that extends from the chamber to an outlet orifice. One or more spray-modifying features (204) are preferably formed within the outlet passageway.</p> |
