A container for storing liquefied gas and for delivering the liquefied gas in either gas or liquid form is provided, the container having an inner vessel which holds the liquefied gas and an outer shell spaced apart therefrom, creating an evacuable spae between the inner vessel and outer shell. The inner vessel is suspended from the outer shell by a necktube. An upper necktube support structure which minimizes necktube damage or rupture from impact or other lateral forces includes a lateral support disc extending across a space between a cylindrical collar surrounding a portion of the necktube and the interior surface of the upper head of the outer vessel. The lateral support disc and the cylindrical collar are spaced apart by an insulative annular sleeve, while the disc is supported at its peripheral edge on insulative bosses and is spaced from an insulative ring extending around the circumference of the interior surface to provide a double heat break. A lateral support structure of similar design is provided at a lower end of the inner vessel. The container further employs a heat exchanger integral with the wall of the outer vessel, a gas line withdrawal conduit telescoped within a liquid line withdrawal conduit, and an economizer circuit which affords simplicity of design and ease of manufacture.
