性能が低下するということが指摘されていた。In the case of the above-mentioned known heat insulating structure, the thickness of the aluminum vapor deposited layer of the metal vapor deposited film used for the synthetic resin thin film constituting the container can only be obtained as thin as measured in angstroms. However, the gas barrier properties are poor, and the airtightness inside the insulation structure cannot be maintained for a long time.
7 It is difficult to maintain the airtightness of the insulation structure, and as time passes, external air, water vapor, Freon-11 gas, etc. can enter the inside of the insulation structure through the thin synthetic resin I9 containing the metal-deposited film, and the airtightness of the structure can be compromised. It has been pointed out that this causes the insulation to deteriorate.

In order to improve the mutual closeness, the extra length portion 15 extending around the periphery (four circumferences 122) of the heat insulating structure a in the state of FIGS. 6 and 7 is insulated as shown in FIG. 8. When the folding process is performed so as to make it contact with the side surface of the structure a, a pinhole or ooze occurs in the aluminum foil layer 14 located at the folded part, and air flows inside from the pinhole part. This has the disadvantage that airtightness is lost as a result.

It is formed by thermally welding the peripheral edges of 11, but when welding and integrating the two, in order to make it possible to thermally weld the synthetic resin thin films on both the front and back sides, the synthetic resin thin films that will be the joint surfaces of each other are It is important to use a material that can be thermally welded, such as a polyethylene film, for the resin thin film 11.11. (See the enlarged partial view of FIG. 2 and FIGS. 4 and 5.) Also, the layer of aluminum foil 14 laminated on the surface of the metal vapor deposited film 12 is placed on the top surface of the layer of synthetic resin 12 as illustrated in FIG. Although the aluminum foil 14 may be left exposed as it is, in consideration of later workability, a coating layer 16 of another synthetic resin film is placed on the upper surface of the aluminum foil 14 as shown in FIG.
It is desirable to protect the surface of the aluminum foil 14 by laminating the aluminum foil 14 with the aluminum foil 14.

しい。Note that the synthetic resin thin film 11 is laminated with a metal vapor deposited film on one side of which is integrally formed with a layer of Alu-i foil 14.
Although it may be used for both the front and back sheets constituting the container 1, from an economical point of view it is desirable to use it on the side facing the high temperature side of the surface to be insulated. (This is because gas movement mainly diffuses from the high temperature side to the low temperature side.) Also, in the example, an example is shown in which a layer of aluminum foil 14 is laminated on the back side of the metallized film, but the present invention is not limited to this. Alternatively, for example, the aluminum foil layer 14 may be polymerized so as to face the aluminum vapor deposited layer 13 and laminated integrally. (In this case, the container 1 is made of synthetic resin film 11 +
Aluminum foil 14 + aluminum vapor deposition layer 13 + synthetic resin layer 12 (
