Abstract: A LIQUID STORAGE CONTAINER INCLUDES INNER AND OUTER VESSELS SPACED FROM ONE ANOTHER TO DEFINE AN INSULATING SPACE THEREBETWEEN. IN ONE FORM OF THE INVENTION, THE SIDE WALLS OF THE INNER AND OUTER VESSELS EACH HAVE RESILIENT BLANKET MEANS DISPOSED ADJACENT THERETO AND DEFINING A SPACE THEREBETWEEN. THE SPACE BETWEEN THE RESILIENT BLANKET MEANS IS FILLED WITH A MASS OF SUBSTANTIALLY FREEFLOWING LIGHTWEIGHT THERMAL INSULATING MATERIAL. THE ROOF OF THE INNER VESSEL IS SUPPORTED BY SUPPORT MEANS DISPOSED WITHIN THE INNER VESSEL AND EXTENDING VERTICALLY UPWARDLY THEREWITHIN. A ROOF OF THE OUTER VESSEL IN ANOTHER FORM OF THE INVENTION IS SUPPORTED BY SUPPORT MEANS SUPPORTED BY THE ROOF OF THE INNER VESSEL. FURTHER MODIFICATIONS OF THE INVENTIONAL INCLUDE A VESSEL HAVING ONLY ONE SIDE WALL WITH INSULATING MEANS DISPOSED IN SURROUNDING RELATIONSHIP TO THE SIDE WALL AND HELD IN PLACE ADJACENT THE OUTER SURFACE THEREOF.
