Refrigerator door () includes outer packaging material () including a resin sheet, and a core material and gas adsorption each contained in outer packaging material (). The gas adsorption device includes a vacuum sealed container containing a gas adsorbing substance that adsorbs various gases, an opening pin that opens the vacuum sealed container by a physical load from an outside, and a load-bearing spacer that suppresses displacement of the opening pin to less than or equal to a predetermined amount.

Vacuum insulation material, and thermally insulating container and thermally insulating wall using same

A vacuum heat insulation material includes outer covering material which has a gas barrier property and a core material that is provided in an inside of outer covering material, the inside of the outer covering material being vacuum sealed, in which a sealed portion that is configured by sealing the peripheral edge of outer covering material, fin that is formed on the peripheral edge of outer covering material, and compressed portion which is formed by a protrusion being compressed, the protrusion is generated when the peripheral edge of outer covering material is folded back toward the core material are provided. Thereby, it is possible to provide a vacuum heat insulation material that is able to suppress reduction of a heat insulation property when a plurality of sheets are disposed lined up.

Vacuum thermal insulation material

The present invention provides a refrigerator with improved refrigerator box strength and high heat insulating performance, which is configured such that external deformation due to entry of air into a vacuum heat insulating material, the entry of air being caused by aging degradation, is prevented. The present invention includes: a heat-insulated box including an inner casing and an outer casing, in which space between the inner casing and the outer casing is filled with a foamed heat insulating material; and a vacuum heat insulating material disposed in at least a side wall of the heat-insulated box together with the foamed heat insulating material, the vacuum heat insulating material including an outer skin material, the outer skin material including at least a core material and being decompression-sealed. The vacuum heat insulating material includes a gas adsorbent. Since the vacuum heat insulating material including the gas adsorbent is included in the side wall, which tends to be greatly distorted among the heat insulating walls of the refrigerator, the rigidity of the side wall is improved and aging degradation of the vacuum heat insulating material is suppressed. As a result, the rigidity of the heat-insulated box can be maintained for a long term, and external deformation of the outer casing of the body can be prevented.

Refrigerator and vacuum heat insulating material for use in refrigerator

A vacuum insulation material includes: a core member having a large number of minute spaces; a cover member having an internal space in which the core member is housed, the internal pressure being decompression-sealed; and an inspection member provided between the core member and the cover member. The inspection member includes a retaining portion disposed on the core member and a hole formed in the retaining portion.
