| titleOfInvention | Pressurised Aerosol Dispensers |
| abstract | An aerosol dispensing device for a pressurized container containing a liquid product composition in a lower product layer, an intermediate liquid propellant layer and an upper vapor propellant layer, comprises valve and diptube means adapted to draw off simultaneously product and liquid propellant to said valve means, said diptube means extending to a point near the bottom of said container, and comprising means permeable only to said liquid propellant and means impermeable to said product and vapor propellant and being open to said product layer. The diptube means may comprise separate dip tubes either side-by-side as shown, or concentric tubes. The tube 13 is open and impermeable to the product and the tube 19 is impermeable to the product but permeable to the liquid propellant. Liquid from the two tubes mix in the valve 6 which may also have a vapour tap 18. Alternatively the diptube means may comprise a single tube of composite construction. <IMAGE> |
