ABSTRACT:
The stationary or mobile container makes possible containing or shipping of solid, liquid, powdery, granular or gaseous substances and in particular that are toxic, dangerous, polluted or, in any case, harmful to health and the environment. It comprises an outside wall (1), for example of metal, a protective inside wall in one or more layers (2, 3), unattackable or in any case inert with respect to the substances contained in it, self-sealing in case of perforation or tearing of outside wall (1) and elastically deformable to compensate for the change in volume caused by deformations of the container in case of impact so that the inside pressure remains almost constant and, an optional expanding additional container (4) connected by a check valve (5) to protective inside wall (2, 3).
