摘要： PROBLEM TO BE SOLVED: To maintain a sure vacuum sealed state even with the generation of slow leak to a first vacuum seal part by providing the first vacuum seal part for vacuum-sealing an exhaust port of a vacuum-insulated body after vacuum exhaust, and a second vacuum seal part for vacuum-sealing a part outside of the first vacuum seal part. SOLUTION: In a vacuum-insulated body of double structure vacuum- exhausted after filling powder vacuum heat insulating material between an external wall and an internal wall, the inside of a space 2 is vacuum-exhausted to a specified level through an exhaust port 1, and a sealing plug 4 is screwed into an internal thread part 3. At this time, a gasket 11 made of soft metal is firmly inserted between cutting edge parts 8, 10 to aim at vacuum sealing. In this case, a first step part 7 is formed around the exhaust port 1 in an annular member 6, and a second step part 15 is formed around the first step part 7. A flange 17 is then fitted to the annular member 6 by bolts 18 so as to hold the soft metal gasket 20 firmly between the cutting edge parts 16, 19, thus aiming at double vacuum sealing.

摘要： PURPOSE: To secure handling performance and constructing performance and completely prevent the deformation of a vacuum insulator after evacuation by sewing a laminated body in the state of being compressed in the laminated direction to the density withstanding atmospheric pressure to vacuum, with a string, formed of material decomposed by gasification at the specific temperature or lower in the air, piercing in the thickness direction. CONSTITUTION: A laminated body 3 formed by alternately laminating a large number of metallic foil 1 with a low heat radiation rate and silica group inorganic fiber sheets 2 is compressed in the laminated direction to the density withstanding atmospheric pressure to vacuum and in this compressed state sewn with a thread, formed of material decomposed by gasification at 500 deg.C or less in the air, piercing in the thickness direction to form a filler for a vacuum insulator. Since the laminated body formed by alternately laminating a large number of metallic foil 1 with a low heat radiation rate and silica group inorganic fiber sheets 2 is sewn with the string 4 in the compact state, the laminated body 3 is integrated by this string 4, and handling performance and constructing performance are secured.

摘要： PURPOSE: To reduce the heat loss in the opening part of a container body by forming a taper that can come in close contact with a lid, at an opening part or in its vicinity. CONSTITUTION: The external wall 14 of a container body 11 is formed in taper shape over the whole wall so as to be gradually tapered toward an opening part 12 from the bottom part of the container body 11. With such a constitution, even if there is a certain degree of difference between the outer dimension of the container body 11 and the inner dimension of a lid 17, the external wall 14 of the container body 11 and the internal wall 18 of the lid 17 are brought into close contact with each other at one place without fail because of the tapered structure of the external wall 14 of the container body 11 so as to prevent the generation of a clearance between the container body 11 and the lid 17. As a result, there is no lowering of heat insulating performance between the container body 11 and the lid 17 so as to prevent the generation of heat loss at that part.

摘要： PURPOSE:To measure degree of vacuum accurately in a short time without disturbing production of the vacuum insulator and without generating problem after production. CONSTITUTION:Inside of the small chamber 11 fixed in airtight state on the surface of an outer vessel 13 of vacuum insulator vessel 11 is evacuated in vacuum to the equivalent level of the inside of a vacuum insulation later 14 of the vacuum insulator vessel 11. The outer vessel 13 part facing to inside of the small chamber 17 in vacuum state is opened in penetrated state with drill shape hit shaft 21. By this, the small chamber 17 and the vacuum insulation later 14 are connected and so the degree of vacuum in the vacuum insulation layer 14 is measured with a vacuum sensor 31 connecting to the small chamber 17.
