The reservoir consists of a metal outer shell 1, 2, 3 and an adherent inner shell 10 produced by rotational molding from a thermoplastic material capable of undergoing shrinkage after molding and, after molding and removal of this shell, an elastomeric resin is injected between the outer casing 1, 2, 3 and the inner casing 10 so as to fill the space 11 created between these casings and to secure them on all their facing surfaces. |
