  • Publication number: 20100025275
    Abstract: A container for transport and storage of liquids comprises a pallet and a metal cage of standard dimensions. The container comprises also an inner bag made of plastic material, an outer envelope disposed between the inner bag and the metal cage, and fastened to the metal cage. The inner bag is not fastened to the outer envelope and is configured to be filled to unfold from an empty condition, in which the inner bag is in a flattened and folded configuration to a filled condition, in which the inner bag is in a parallelepipedal and unfolded configuration, having a volume corresponding substantially to the volume of the housing of the cage and being surrounded by the outer envelope and the metal cage.

  • Patent number: 7556720
    Abstract: Container for the storage and/or transportation of liquids or powders, in particular inflammables, suitable for preventing the formation of electrostatic charge, comprising a tank supported by a pallet, housed in a metallic cage and having an outer surface in contact with said metallic cage. The tank comprises a base layer of plastic material, a layer modified through plasma and a layer of metallic material deposited with vacuum PVD (Physical Vapor Deposition )technique. The metallic layer is in contact with the cage. The metallization of a plastic tank is carried out by generating in a chamber a plasma which activates the outer surface of said tank so as to form a surface layer and carrying out, with vacuum PVD technique, the deposition of a layer of conductive metallic material superposing said surface layer to obtain a tank metallized on the outside.
