A heat-insulating container being used under an environment where exposure to water of liquid is possible, includes a container main body having a substance holding portion which holds a substance at a temperature which is lower than a normal temperature on the inside of the substance holding portion; and a heat-insulating structure body which is provided in the container main body and includes at least a vacuum heat-insulating material. In addition, the vacuum heat-insulating material includes an outer cover material and an inner member sealed in a tightly closed and decompressed state on an inside of the outer cover material. In addition, the inner member is configured of a material which does not generate hydrogen in a case of coming into contact with the moisture of the liquid.

The present invention is directed to a reinforcement method for a cylindrical high-pressure tank reinforced by FRP prepreg bandage, totally. For that purpose, this invention developed the manufacturing process for the internal metallic tank assembly where its diameter is comparatively large. It is effective for lightening weight of a high-pressure tank.

Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.

A storage container for liquefied gas, having a first, inner tank extending in a horizontal longitudinal direction and configured to store the liquefied gas, a second, outer tank disposed around the first tank, the container having a device for supporting the first tank in the second tank, the support device having a fixed and rigid connection extending in a longitudinal direction (A) between one end of the second tank and an adjacent end of the first tank, the fixed and rigid connection including a set of walls forming back-and-forths in the longitudinal direction (A) to constitute a thermal insulation path between the second tank and the first tank, wherein the set of walls forming back-and-forths in the longitudinal direction (A) of the fixed and rigid connection has at least one wall made of titanium.
