In FIG. 1, 1 is an inner wall made of a stainless steel plate having a wall thickness of about 0.8 to 1.5 mm, and 2 is a wall thickness of 1.0 to 3.
The outer wall is made of a stainless steel plate of about 0 mm, and the ends of the inner wall 1 and the outer wall 2 are sealed by the sealing material 5 welded around the opening , and the space between the inner wall 1 and the outer wall 2 is vacuum. It is said that. Further, 3 is a heat insulating material such as a glass board filled in this space.

It is formed on the entire surface of the adjacent inner wall 1. In this embodiment, since there are a plurality of bent portions 6, the amount of absorption of thermal expansion of each bent portion 6 is small, and the depth of the bent portion 6 can be reduced to 15 mm or less. The rigidity can be increased.

納するときに邪魔になることがない。 The vacuum insulation container of the present invention constructed as above is used for housing the high temperature battery 4 therein, and the inner wall 1 is opposed to the outer wall 2 by the high temperature of about 300 to 350 ° C. The thermal expansion is the same as the conventional one. However, in the present invention, the bent portion 6 is formed at a required portion of the inner wall 1 adjacent to the opening , and the expansion of the inner wall 1 is absorbed by the deformation of the bent portion 6 as shown in FIG. The end sealing material 5 is not pushed out. Therefore, the vacuum heat insulating container of the present invention has an advantage that the welded portion of the seal material 5 is not damaged and air does not enter from the outside, so that excellent heat insulating property can be always maintained. In addition, the bent portion 6 is bent to the outer wall side.
Since it is installed on the inner wall 1, the high temperature battery 4 is stored from the opening.
It does not get in the way when it is delivered.
