Flexible receptacle for fluids, which receptacle comprises a cylindrical outer casing (1) and an inner bag. The casing is formed by a hose which is doubled up at one end of the receptacle so as to obtain a casing (1) with a double wall. The strength properties of the casing can be considerably improved if the casing in the portions positioned in the vicinity of the doubled end of the receptacle are twisted around the central axis of the receptacle with respect to the mantle face of the receptacle. |
