Definitions

  • the present invention relates to an aerosol dispenser which uses compressed air as the propellant.
  • the adoption of this dispenser as a substitute for ordinary household aerosols eliminates the use of chemical propellants such as chlorofluorocarbons or hydrocarbons; solid waste is also reduced.
  • the dispenser which uses a non-disposable compressor section coupled to a recyclable or refillable product container, uses air as the propellant. This is generated by the natural act of shaking the dispenser a few times before using which compresses air via a small pump located inside the unit.
  • a side coupled aerosol container improves the prior art with the following novel features.
  • a side coupled two-part dispenser with one key difference.
  • the pump module can be decoupled and shared with other product modules. The product module stays pressurized even when decoupled, and the liquid product remains sealed by the check valve.
  • a refillable dispenser is provided wherein a compressor assembly is attached to a screw-on cap, thereby permitting the use of standard blow molded or metallic or even glass containers.
  • the volume within the compressor housing is vented through the cap but is isolated from the pressurized container.
  • the present invention improves the prior art with the following novel features.
  • the outer housing splits apart to permit the insertion and removal of factory filled recyclable product containers.
  • a further improvement is provided in the use of tapered bellows as a pumping air compressor elements.
  • the present invention includes a liquid module containing a liquid to be sprayed, and a pump module with an air compressor pumping means, with the liquid spray flowing in response to urging by the compressed air.
  • a piston and cylinder type of compressor is a workable solution.
  • sizing the stroke, bore and driving weight is a compromise which stacks a desire for quick pressure build ⁇ up of an unpressurized depleted container against a desire for high maximum pressure with a given weight and oscillatory frequency. A bellows would pose a similar compromise.
  • the pumping means of the pumping module may use a piston and cylinder compressor wherein the cylinder is an integral part of the recyclable product container.
  • a reusable weight disk attached to the discharge hose is clipped onto the product container with the same motion required to pierce the seal on the container top to attach the discharge hose coupling to the dip tube which is integral to the container.
  • the product container may be a standard type metal can or a plastic container.
  • the pumping means of the pumping module may alternatively use a tapered bellows compressor.
  • the tapered bellows version permits more standard can manufacture in that a cylinder and outlet check valve need not be part of the can bottom as in the piston and cylinder case.
  • the internal product container is guided by the sides of the housing in its pumping excursions.
  • the product container is removed or inserted in a manner very similar to replacing batteries in a flashlight.
  • the piston and cylinder pumping module may be further modified with a telescoping piston and cylinder assembly.
  • this particular assembly has three cylinders which nest into each other and a small piston.
  • Appropriate seals must be fitted to each section and extension limits (strings) must be used to limit the excursion of each section during the fill stroke. This achieves some advantage in that with low back pressure, such as in a startup condition or in a depleted pressure situation in a product container, the entire array will be flattened to a significant height, thus compressing a large volume of air per stroke. As the back pressure quickly builds up, the down stroke force will no longer be adequate to compress the air in the largest cylinder. In effect, the large section decouples and stays dormant. The upper sections keep pumping until back pressure decouples the next section and so forth until finally, even the top solid piston "locks up" against back pressure.
  • a preferred process is to take a completed bellows of any manufacture and to apply reinforcing fibers in the circumferential direction by first dipping the bellows in appropriate adhesive and then rolling on the fiber reinforcement.
  • This thickening of selected portions of the bellows surface supplies just the right kind of an anisotropic reinforcement, to resist radial expansion, while not adversely affecting the longitudinal suppleness of folding capability.
  • even inexpensive dip molded bellows of thin uniform cross section can be made usable for this application.
  • the narrow section of the bellows is extended a few convolutions.
  • the top section is made a bit wider than the design point would suggest, with shallower convolutions and a larger root diameter. This in itself reduces the tendency to bend, but it may not produce the desired high pressure. The latter capability can be restored, while at the same time insuring straight folding without bending, by fitting the top section of the tapered bellows with a short guide rod internally that takes up most of the root diameter of the extended section of small convolutions. The effective volume of this top section is reduced by the rod volume, thereby insuring high pressure results.
