DUAL CHAMBER DISPENSER PUMP

摘要

This invention relates to pump-action nozzle devices and methods of making t he same. The dispenser nozzles of the invention comprises a body which defines two or more internal chambers, both having outlets and at least one of which has an inlet (104a, 104b) through which fluid may be drawn into said chamber . 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 (400) which in turn engages a resiliently deformable/displacable portion of the body of the device that defines the chamber, thereby compressing the chamber and actuating the dispensing of fluid. The additional chamber(s) may contain further liquids or gaseous substance (e.g. air). In preferred embodiments, the actuator is an over cap or a trigger actuator.
