In a fuel tank and a process for manufacturing the fuel tank, accessories emerging through the wall of the tank are covered by a flexible film of multilayer structure that includes a fuel barrier layer. The perimeter of the film is welded to the wall of the tank.

Fuel tank and method for making same

System for closing off an opening in a plastic tank, formed from a sheet of multilayer plastic that includes a barrier layer, the said sheet being welded around the perimeter of the opening and provided with a peripheral region that is slimmed down so as to effectively restrict the permeation of gases and liquids into the layer located between the tank and the barrier layer. Method of closing of a tank by welding such a plate, comprising the welding of the slimmed-down peripheral part by the technique of laser or infrared radiation welding. Use of the method to close off a fuel tank for a motor vehicle.

System and method for sealing a tank opening

Process for manufacturing hollow plastic bodies, especially motor-vehicle fuel tanks, from an extruded parison of closed cross section, in which at least one cut is made in the parison which is then formed by moulding.

Process for manufacturing hollow plastic bodies

Process for manufacturing hollow plastic bodies, especially motor-vehicle fuel tanks, from an extruded parison of closed cross section, in which at least one cut is made in the parison which is then formed by molding.

System and for sealing an opening of a plastic tank with a multilayer wall by means of a multilayer plate itself constituted by a polymer structure including at least one internal barrier layer and an exterior layer compatible with the exterior layer of the tank wall. The multilayer plate is welded over an opening in the tank and the plate and the wall of the tank are superimposed so that the number of superimposed layers is equal to the sum of the number of layers in the plate and the number of layers in the wall of the tank.

System and method for closing a tank opening

Process for manufacturing a plastic fuel tank from two shells formed by molding, which are joined together, at least one shell being produced by compression-molding a portion of a plastic sheet between a mold and a punch and by the remaining portion of the sheet being blow-molded in the region not compression-molded.

Method for making a fuel tank in plastic material

Fuel tank comprising a canister containing a composition capable of retaining fuel vapours and which is associated with an overfill prevention device also located inside the tank.
