<p>This invention relates to improved dispenser nozzles and methods of making the same. The dispenser nozzles of the invention comprises a body which define two or more internal chambers, both of which have outlets and at least one of which has an inlet. The inlet comprises an inlet valve and the outlet comprises an outlet valve. Fluid is dispensed from the dispenser nozzles by applying a pressure to a resiliently deformable or 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.</p> |
