Abstract

A novel dual bladder-type aerosol power system which can be used in a standard aerosol spray container. The aerosol powering system utilizes a dual independent rubber-type bladder combination to generate the expulsion power for the aerosol. A power system for an aerosol spray generating nozzle comprising: (a) a nozzle adapted to generate an aerosol vapor spray; (b) an inner hollow resilient power bladder connected to the nozzle, the resilient bladder being adapted to contain the liquid used to generate the aerosol spray, and (c) an outer resilient power bladder enveloping the inner bladder, the inner and outer bladders cooperating to generate a pressure on the liquid when filled with the liquid.

Claims

1. An aerosol spray generating power system comprising:

(a) a nozzle adapted to generate an aerosol vapour spray from a pressurized liquid;

(b) a first hollow elastic resilient open-ended closed bottom elongated cylindrical power tube, the open end communicating with the nozzle, the elastic resilient power tube having a circular flange around the open-end being adapted to contain liquid used to create the aerosol spray, the resilient power tube storing elastic energy on being expanded with a liquid and generating a pressure on the liquid when the resilient power tube is expanded with the liquid, the first power tube exerting an expelling force on the liquid when the nozzle is opened; and

(c) a second hollow elastic resilient open-ended closed bottom elongated cylindrical power tube of an internal diameter greater than the external diameter of the first power tube, located on the exterior of the first resilient power tube, and being of a length longer than the first power tube to form a space between the closed bottom of the first power tube and the closed bottom of the second power tube, the second power tube having a circular flange around the open-end adapted to mate with the circular flange of the first power tube, the resilient second power tube storing elastic energy on being expanded with the liquid in the first power tube and generating a pressure on the liquid when the resilient second power tube is expanded with the liquid, the first resilient power tube and the second resilient power tube being independent of one another in movement but cooperating together when expanded with the liquid in the first hollow power tube to provide a cumulative pressure on the liquid to thereby together dispense the liquid through the nozzle when the nozzle is open; and

(d) a collar connected to the base of the nozzle and being adapted to hold the mating flanges of the first and second power tubes and thereby causing the open end of the first power tube and the open end of the second power tube to communicate with the nozzle.

2. An apparatus as defined in claim 1 wherein the first resilient power tube acts as a liner which separates the liquid from the second resilient power tube.

3. An apparatus as defined in claim 2 wherein the first resilient power tube is formed of a material selected from the group of materials consisting of food grade silicone rubber, natural latex, and Neoprene.

4. An apparatus as defined in claim 1 wherein the second resilient power tube is formed of natural rubber.

5. An apparatus as defined in claim 4 wherein the second resilient power tube is capable of expanding at least about 600%.

6. An apparatus as defined in claim 5 wherein the first resilient power tube is capable of expanding at least about 800%.

7. An apparatus as defined in claim 6 wherein the first resilient power tube and the second resilient power tube are housed in a container, and the nozzle is located at the top of the container and is attached to the container and attached by the collar to the open ends of the pair of power tubes.
