  • Patent number: 4098426
    Abstract: The improved double-walled transport container for transporting liquids and gases which have to be protected against heating or cooling and against mechanical shock, has a fully insulated inner vessel and an outer vessel comprising an upper shell, a lower shell and two dished endwalls. A shock-absorbing and thermally insulating layer is provided between the outer and the inner vessel, and support flanges extend over the entire length of the outer vessel. The sum of the distances between the endwalls of the inner and the outer vessel is at least equal to the distance of the crest of the arch from the edge of an endwall of the outer vessel.
