Abstract
A double-walled container having spaced-apart inner and outer wall members enclosing a sealed insulation space, with at least a portion of the wall members being formed of a polymeric thermoplastic material selected from the group consisting of polyethylene, polypropylene, polytetrafluoroethylene and polychlortrifluoroethylene, uncoated with any permeation barrier coatings, so as to be gas permeable. A mass of pelletized adsorbent is disposed in the insulation space in thermal contact with the inner wall member. The introduction of cryogenic liquid to the container effects cooling of the inner wall member and adsorbent in thermal contact therewith, thereby causing increased adsorption of gas in the insulation space by the adsorbent for reduction of pressure therein and enhancement of the insulation quality of the insulation space. Complete removal of cryogenic liquid from the container effects warming of the inner wall member and adsorbent, thereby causing desorption of gas from the adsorbent disposed in the insulation space to raise pressure therein and cause pressure in the insulation space above pressure of the exterior environment of the container to be at least partially relieved by flow of gas through the polymeric thermoplastic wall member portion from the insulation space to the exterior environment.
