Definitions

  • This invention relates to a method for producing metal bases for delivery devices such as aerosol valves, metering pumps and/or atomizers and the like, where said bases are used to fix said devices onto the aperture of a metal can or other vessel which is to contain the product or products to be delivered.
  • the invention also relates to the metal base produced.
  • the bases in question are produced by pressing steel or aluminium alloy sheet.
  • the steel sheet can be tin-, chromium- or nickel-­plated to protect it form oxidation.
  • the sheet is varnished with a protective varnish, for example epoxide-bases.
  • the main object of the present invention is therefore to provide a method for producing a base which not only obviates the aforesaid drawback but also enables the seal between the base and the vessel on which it is fixed to be made without the need to use the conventional gasket.
  • a further object of the present invention is to provide a method which enables bases to be produced in two colours, thus satisfying certain commercial requirements.
  • the reference numeral 1 indicates an aerosol container comprising a preferably metal can or vessel 2 for containing the product or products to be delivered plus the propellant.
  • the can 2 upperly comprises a wide aperture flanged at its edge 3.
  • a base 4 which supports the delivery valve 5 in conventional manner is fixed onto this aperture by clinching along its edge.
  • This valve is also conventional and can be different from that shown, which in this case comprises a delivery button 6, a valving element 7 on which the button is mounted, a gasket 10, a compression spring 8 acting on the valving element, and a member 9 which retains the entire assembly and on which there is fixed a dip tube 11 through which the product is withdrawn from the bottom of the container 2.
  • the base 4 ( Figures 2 and 3) is formed by conventional methods (pressing) from untreated steel or aluminium alloy sheet.
  • untreated as used in the text and in the accompanying claims signifies that no layer or coating of plastics material exists on the starting sheet.
  • the steel sheet can however be tin-, chromium- or nickel-plated.
  • the base is hot-coated with a layer of plastics material, preferably polyethylene or polypropylene, by immersion or spraying, or in a fluidized-bed, or by other conventional methods.
  • plastics material preferably polyethylene or polypropylene
  • the polyethylene can be dissolved (if necessary with heat) in an organic solvent such as cycloaliphatic or aromatic hydrocarbons, and sprayed on the preferably hot base by usual spray guns, or alternatively the base can be immersed in such a solution.
  • the known fluidized-bed method can also be used to coat the base. Hot polythene in the liquid state can also be sprayed onto the base or the base can be immersed in a polyethylene bath.
  • the spraying method enables different plastics materials, for example in terms of their colour, to be applied to the base.
  • plastics materials for example in terms of their colour
  • this accumulation constitutes an effective seal element when the base is fixed to the vessel 2.
  • Such an accumulation can be obtained during spraying by accentuating the application in the appropriate points.
  • the spraying method is also suitable for applying two different materials, one on the inner surface and the other on the outer surface.
  • the two materials can be different in terms of physical properties. For example a more elastic material can be applied to the inner side A and a different colour material can be applied to the outer side B.
  • Figure 3 The base 4 of this figure is hot-sprayed at points C and D with elastic, chemically resistant plastics material able to provide good sealing on fitting to the vessel. At the points E, coloured protective plastics material is hot-sprayed.
  • the invention also enables the coating to be obtained at the punch-cut points of regions Z, so that in contrast to known bases, the base of the invention is effectively protected in these regions against oxidation.
  • the invention is not limited to the described embodiments, and covers all modification within the same inventive scope.
  • the coating can also be only partial and be applied only to those regions which it is required to protect.
