Abstract

A storage container for cryogenic liquids has an outer container and at least one inner container, an insulation space being situated between the outer container and the inner container or containers. The outer container and/or the inner container have devices for strengthening the container walls. The devices for strengthening the container wall of the outer container and/or of the inner container are constructed as at least one web arranged on the container wall of the outer container and/or of the inner container and/or as at least one supporting plate adapted essentially to the cross-section of the inner container.

Claims

1. A storage container assembly for storing cryogenic liquids, comprising:

an outer container;

an inner container disposed inside the outer container with an insulation space between facing walls of the outer and inner container;

strengthening devices on walls of at least one of the outer and inner containers,

wherein said strengthening devices include a plurality of webs connected at exterior parts of the outer container walls, a plurality of flat supporting plates extending between and connected to facing walls of the inner container, and a plurality of support members which extend through the inner container and are connected at opposite ends of the support members with walls of the outer container, said support members being configured so as to provide no heat-conducting connection between the inner and outer containers, and

wherein said support members are disposed between and spaced from respective ones of the supporting plates.
