Patent

CA 2514014

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.

L~invention concerne des buses perfectionnées pour vaporisateurs, ainsi que leurs procédés de fabrication. Ces buses comportent un corps définissant au moins deux chambres internes, chacune possédant des orifices de sortie, et au moins une présentant un orifice d~admission. L~orifice d~admission est pourvu d~une soupape d~admission et l~orifice de sortie est doté d~une soupape de refoulement. La distribution du fluide s~effectue depuis les buses du vaporisateur par application d~une pression sur une partie élastiquement déformable ou déplaçable du corps du dispositif définissant la chambre, laquelle se trouve ainsi soumise à une compression déclenchant la diffusion du fluide. La ou les chambres supplémentaires peuvent renfermer d~autres liquides ou une substance gazeuse (par exemple de l~air). Dans des modes préférés de réalisation, le poussoir de commande est une coiffe ou un poussoir à gâchette.
