The outer plate 1 is shaped like a container, and the inner plate 5 has a bank 5'projecting in a direction opposite to the outer plate 1. The outer plate 1 and the inner plate 5 are fixed by screws 6. And, the heat insulating pack 2 has a powder filling inside,
The inside was covered with a bag made of a metal-plastic laminate film and the inside pressure was reduced to 10 -1 Torr. Therefore, the surface of the heat insulating pack 2 is covered with a flexible bag, and since there is a powder filling, it is difficult to obtain flatness on the surface of the bag, and therefore wrinkles occur on the surface. Therefore, it is difficult for the heat insulating pack 2 and the outer plate 1 to come into close contact with each other, and a gap C is formed between them. Therefore,
Freon gas in the foamed heat insulating material 4 accumulates in the gap C, and if one of them is cooled or heated, the temperature change causes the freon gas to contract and expand, resulting in a corrugated deformation of the outer plate 1. Was there.

The length A of the opening of the outer plate 1 is formed larger than the length E of the heat insulating pack 2, and the outer plate 1 of the first heat insulating material is formed.
The distance C between the heat insulating pack 2 and the heat insulating pack 2 is smaller than the thickness B of the heat insulating pack 2. Reference numeral 8 denotes a second heat insulating material which is attached to the inner plate 5 and has a recess formed in a shape along one surface of the heat insulating pack 2. The length F of the recess is the same as the total length E of the heat insulating pack 2 and the thickness G Is greater than the distance C between the skin 1 and the heat insulating pack 2.

EFFECTS OF THE INVENTION As described above, the present invention includes an outer plate, an inner plate arranged at a predetermined distance from the outer plate, a heat insulating pack arranged between the both plates, and the outer plate. It is composed of a first heat insulating material and a second heat insulating material which are attached to an inner plate and have a recess formed in a shape along one side of the heat insulating pack, and the distance between the outer plate and the heat insulating pack is made smaller than the thickness of the heat insulating pack. And the opening length of the recess of the second heat insulating material is the same as the total length of the heat insulating pack, and the opening thickness is larger than the distance between the outer plate and the heat insulating pack,
A heat insulating pack is housed between the recesses of the first heat insulating material and the second heat insulating material. Since the first heat insulating material is interposed between the outer plate and the heat insulating pack, a gap is generated as in the conventional case. Fluorocarbon gas will not accumulate and will not deform the skin. Also, because the opening of the outer plate is formed larger than the heat insulation pack,
When storing the insulation pack, it does not damage the vacuum and break the vacuum.
