Process for manufacturing a plastic fuel tank (FT) equipped with an internal accessory, by molding a parison using a mold comprising two cavities and a core, said process comprising the following steps: the parison is introduced into the mold cavities; the core is introduced inside the parison, the core having first been fitted with the accessory; the mold is closed so that the cavities come into leaktight contact with the core; the parison is pressed against the cavities by blowing through the core and/or applying a vacuum behind the cavities; the accessory is fastened to the parison by snap riveting using a device attached to the core; the mold is opened to withdraw the core; and the final molding of the parison is carried out by blow molding and/or thermoforming. The accessory comprises an orifice for the snap riveting and at least one protuberance which, during the fastening of the accessory by snap riveting, will at least partially melt to form a local weld which is at another location than the obtained rivet to obtain two different attachment points.

Liquid tank and method for manufacturing it

Method for fastening an accessory () at at least two points of a wall of a plastic fuel tank, this fastening taking place during the actual manufacture of the tank by molding. According to this method, the accessory () is provided, at least at one of its fastening points, with a fastening part (') in such a way that the accessory () is fastened to the wall of the tank and can move relative to the corresponding fastening point on the wall of the tank ().

Layer made of base plastic comprising, in the dispersed form, nodules with a diameter of less than or equal to one micron comprising barrier plastic incompatible with the base plastic; multilayer structure comprising at least one such layer and process for the manufacture of such layers/structures.

Layer made of base plastic comprising barrier plastic nodules

Method for manufacturing a plastic fuel tank by moulding a parison in a mould, in which method the parison is locally deformed during moulding of the parison in order to obtain an impermeable hollow built-in connector provided with a screw thread, and to do so by means of a concave counter-form and a convex form that can penetrate the counter-form, these two pieces being secured, one to the mould and the other to a core located inside the mould, or vice versa, and at least one of these pieces being provided with a screw thread, the moulding of the connector taking place by the convex form penetrating the concave counter-form.
