<p><P>PROBLEM TO BE SOLVED: To provide a fuel tank made of a synthetic resin which can surely prevent the permeation of a fuel from a welded section between the tank body and an accessory part from occurring, and in addition, which keeps the accessory part combined with the tank body by an excellent strength. <P>SOLUTION: A multi-layer container has an internal layer and an external layer of a polyolefin resin, and has a permeation preventive layer as the intermediate layer. For the multi-layer container for the fuel tank, this member for permeation prevention made of a metal sheet or a foil having an adherent resin layer comprising a polyolefin which is denaturalized by an unsaturated carboxylic acid or its inductor is welded to a discontinuous section of the permeation-preventive layer. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
