(under subclass 560.04) Subject matter wherein the cryogenic container includes an inner vessel made of a thin sheet of material which is flexibly deformable by the internal pressure exerted by the liquefied gas.
(1) Note. The thin sheet of material normally comes into contact with the inside surface of the adjacent layer--usually insulation--such that the internal pressure of the gas is supported by the outer vessel through the intervening layer or layers.
