Abstract
Abstract A container for cryogenic fluids is described wherein a first layer of insulating blocks completely lines the interior of the container and at least a portion of one face of each block is bonded to the interior of the container by a cryogenic adhesive. The sides of the insulating blocks have a contractable insulating material completely surrounding them. At least a second layer of insulating blocks is bonded to the first layer of blocks; at least about 2 percent of the areas common to the faces of the first and second layers of blocks are bonded. The sides of the second layer of blocks are surrounded by a contractable insulating material. The face areas common to the blocks that are not bonded preferably have a substantially non-friction material attached thereto. The layers of blocks are arranged so that there are no direct heat paths to the walls of the container. A membrane of Mylar polyester film completely covers the interior of the container and is sufficiently bonded to the interior layer of blocks to support the Mylar film. Optionally, another layer of insulating blocks can be bonded to the Mylar film and then another layer of Mylar film bonded to this layer of blocks-this is preferred for containers used in transporting cryogen. Where the container is stationary, the top of the container does not have to have the membrane of Mylar film.
