Definitions
- This invention is directed to a novel bladder-type aerosol power system which can be used in a standard aerosol spray container. More particularly, this invention pertains to an aerosol powering system which utilizes a rubber-type bladder to generate the expulsion power for the aerosol. This system circumvents the need to use volatile propellants which have been demonstrated to be harmful to the protective ozone layer of the earth.
- the protective ozone layer of the earth is shrinking in thickness.
- the ozone layer is critical to the health of living organisms inhabiting the earth because the ozone layer filters out deadly ultra-violent rays, and other rays, emitted by the sun.
- Considerable evidence has been gathered to demonstrate that the damage that is occurring to the ozone layer is caused by a number of civilization generated free radicals and Freeon-type propellents which have been used in aerosol container spray systems for many years. These propellents are lighter than the atmosphere and rise to the elevation of the ozone layer.
- U.S. Patent No. 3,993,069 illustrates a pumping system which utilizes a natural rubber bladder which is inflated and thereby generates pumping action from the force created by the bladder in seeking to return to its original size and shape.
- I have invented an aerosol spray generating system which utilizes a special rubber tube to generate the power required to create the aerosol spray, when the liquid contents in the aerosol can are forced into a spray nozzle.
- a power system for an aerosol spray generating nozzle comprising: (a) nozzle means adapted to generate an aerosol vapour spray; and (b) a hollow resilient means connected to the nozzle means, the resilient means being adapted to contain the liquid used to generate the aerosol spray, and generate a pressure on the liquid when filled with the liquid.
- the resilient means may have a liner which separates the resilient means from the liquid.
- the resilient means may be formed of natural rubber.
- the liner is separate from the resilient means.
- the liner may be formed of a material selected from the group of materials consisting of food grade silicone rubber, natural latex, and Neoprene.
- the resilient means can be capable of expanding at least about 600%.
- the liner can be capable of expanding at least about 800%.
- the resilient means can be constructed in the form of a elongated tube which is closed at one end, is open at the other end, and has a collar around the open end.
- the liner tube can be adapted to fit into the interior of the resilient tube means.
- the apparatus can include a connector means which connects the collars of the liner tube and the resilient tube means with the nozzle means.
- the resilient tube means and the liner tube can be housed in a container, and the nozzle means can be located at the top of the container and attached to the container and the pair of tubes.
- Figure 1 illustrates a side elevation partial section view of the components that make up the bladder powered aerosol can 2.
- a conventional aerosol can 2 has at the top thereof a stamped metal can top 4. Inserted into the interior of the can 2 through can top 4, is a rubber power tube 10, which embraces an inner liner tube 8.
- a conventional aerosol spray nozzle-cap 6 is positioned above the liner tube 8 and the power tube 10.
- a connector 16 and a collar 14 combination is used to enable the various components to be assembled together.
- Figure 1 illustrates a side partial-section view of the manner in which the liner tube 8 and the power tube 10 inflate within the interior of aerosol can 2, when the liner tube 8 is pumped fall of an appropriate consumer product.
- Figure 1 which can be interpreted somewhat as a stylized representation in order to illustrate the function of the invention, the outside of liner tube 8 remains juxtapositioned against the inside of power tube 10.
- the spray top 6 is manually activated, the energy stored in the expanded power tube 10 forces a small portion of the contents of liner tube 8 out to the nozzle of the spray top 6.
- the size of the power tube 10 and the liner tube 8 gradually decrease as the contents of the liner tubes are gradually expelled through repeated activations of nozzle 6.
- Figure 2 illustrates a side elevation view of the liner tube 8.
- This liner tube 8 may be constructed of a number of suitable liquid impermeable resilient materials, depending upon the nature of the contents that are to be packaged in the interior of the liner tube 8.
- the liner tube 8 has a flange 9 around the top thereof. If food items are to be contained in the liner tube, then a food grade quality silicone can be used for construction the liner tube 8.
- the liner tube can be manufactured of natural latex, or a synthetic rubber such as Neoprene, manufactured by Thiokol.
- FIG. 3 illustrates a side elevation view of the power tube 10, with top flange 11.
- the power tube 10 is critical to the successful operation and performance of the aerosol generating power system.
- the power tube 10 is preferably constructed of a natural formulated rubber obtained from Malaysia.
- the natural rubber from which the power tube 10 is formed should be capable of expanding at least 600%.
- the liner 8 should be constructed of a resilient material which can expand in the order of 800 to 1,000%. This is necessary in order to permit the liner tube 8 to remain abutted against the interior of the power tube 10 when inflation or deflation occurs.
- the liner tube 8 must be able to expand proportionately greater than the power tube 10, in order that the two items can remain closely juxtapositioned when the power tube 10 and the liner tube 8 are inflated with the contents that are to be held in the aerosol container.
- Figure 4 illustrates side elevation view the manner in which the liner tube 8 is positioned in the interior of the power tube 10.
- the orientation illustrated in Figure 4 is in the "at-rest" position.
- Figure 5 illustrates in side elevation partial-section view a valve connection arrangement that can be utilized for the liner tube 8-power tube 10 combination.
- the liner tube 8 and power tube 10 are held in place by a collar 14.
- This collar 14 can be molded of a suitable polymer material.
- the liner 8-power tube 10-collar 14 combination are fitted into a connector l6, which is secured to the underside of the can top 4 of the aerosol container.
- Connector 16 has a fill-hole formed therein, which can be utilized for top-filling the liner 8 with the product that is to be packaged in the aerosol container.
- a one way valve is secured to the bottom part of the fill-hole 18 in order to prevent the contents of the aerosol container from exiting through the fill-hole 18 once the aerosol container has been filled.
- Figure 6 illustrates a graphical depiction of the relationship between pressure and air volume as the bladder-like means (power tube 10) is inflated with air.
- the solid line depicts the pressure behaviour of the tube 10 upon first inflation up to 100 millimeters of air.
- the dotted line depicts the pressure behaviour of the tube 10 upon reinflation up to 100 millimeters of air after the power tube 10 has been deflated following the first inflation.
- the pressure rises in a linear manner until a threshold "set" peak is reached. At that point, the pressure drops to a certain extent while the power tube is being inflated with additional air.
- an important advantage of an aerosol powering system according to the invention is that it can be used in any position. It is not necessary to hold the aerosol can upright. Moreover, it operates efficiently at pressures lower than those typically used for propellent powered aerosol container system. Thus, with an aerosol power system according to the invention, it is not necessary to mark the containers as explosive or inflammable. Another important advantage of the aerosol power system of the invention is that no solvent dilution of the consumer product that is contained in the inner liner takes place because there is no propellant or solvent.
- Prototypes of the invention have been constructed utilizing a natural rubber obtained and formulated in Malaysia, and a liner tube 8 formed of natural latex.
- aerosol containers are pressurized to about 60 psi in order to obtain the desired aerosol spray effect.
- This high pressure can be somewhat dangerous, particularly if the aerosol can is heated, eg. thrown into a fire.
- the prototype it has been dis covered need only pressurize the contents of the inner liner 8, and power tube 10 to about 22 psi.
- the pressure-size gradient for the power tube, as it is inflated and then deflated, once it passes a threshold peak is nearly horizontal.
- a liner tube-power tube combination was repeatedly inflated with 100 millimeters of air.
- Various combinations of new power tube and new liner tubes, together with used power tubes and used liner tubes were used.
- the objective of these tests was to determine and record the different elongation and performance properties which the various brands of latex rubber that were used to produce the power tubes and the liner tubes. It was observed that after the third or fourth inflation, there was essentially no significant change in the pressure-volume relationship from further repeated inflations and deflations. To provide consistency in the test results, all inflations were maintained for thirty minutes with fifteen minute intervals between inflations.
