た。2. Description of the Related Art In heat-insulating containers such as thermos bottles, cooler boxes, ice boxes, heat-insulating cups, heat-insulating tableware and heat-insulating lunch boxes, conventional stainless steel inner and outer containers are arranged with a space between them. A metal double-walled container is used in which the outer container is joined and integrated at the mouth of the opening, and the void is evacuated to have a heat insulating function.
Then, in order to further improve the heat insulation performance, a foil of copper or aluminum is arranged to prevent radiant heat, particularly on the surface of the inner container or the outer container facing the void portion, or a plating layer of copper, silver or the like is formed. . However, since the inner and outer containers of this kind of heat-insulating container are made of metal such as stainless steel, it is not possible to see the inside of the container from the side. The reality is that I was peeping from the club. For this reason, by opening the opening each time the inside of the container is checked, heat enters and leaves through the opening, and the original heat retention performance is maintained despite the heat insulation performance originally being maintained as a heat insulating container. There was an inconvenience and a problem that it could not be done.

A level gauge consisting of a pipe is provided. However, in such a structure, since it is a heat-insulating container, it is necessary to insulate the glass level gauge to be installed upright, and it is necessary to stand upright inside the heat-insulating layer or to visually check it. In order to be able to do so, it is necessary to perform processing such as providing a window that maintains airtightness in the stainless steel of the outer container. Therefore, in this case, not only the number of parts is increased, but also the structure is complicated and the manufacturing cost is increased.

And, in the case of the synthetic resin, an air layer is interposed in the void to form a heat insulating layer, or a solid heat insulating material is arranged to form a heat insulating layer, and in the case of glass, the void is evacuated, A heat insulating layer is formed. In the heat insulating container having such a structure, in order to improve heat insulating performance, the surface facing the void is subjected to metal plating for preventing radiant heat or a metal foil is arranged. Therefore, by these,
Despite the fact that the outer container is transparent, the visibility inside the container is blocked, and the inside of the container cannot be viewed. On the other hand, in order to be able to see the inside of the container, it is necessary to omit the metal plating or the provision of the metal foil for preventing the radiant heat, and as a result, there is a problem in that the heat insulation performance is improved.

It is not always necessary to directly form the protective film on 2b and 23b, and a transparent film such as antimony-doped tin oxide that transmits visible light and reflects infrared light is vapor-deposited, sputtered, or ion-plated. The radiant heat prevention film 5a is formed by coating with a coating or the like, and the radiant heat prevention film 5a is formed by winding it around the wall surfaces 22b or 23b facing each other with the void portion 24 of the inner and outer containers 22 and 23 interposed therebetween. It can be arranged. In this case, since the film material of the radiant heat preventive film layer 5 to be attached by vapor deposition, sputtering, or ion plating is expensive, the film of the radiant heat preventive film layer 5 is vapor-deposited, sputtered, or ion-coated on only one side of the film. The film surface is plated and adhered, and
When it is provided so as to be placed on the side, the cost is low and the same radiant heat prevention effect as that provided on both sides can be achieved.
