Abstract: The invention provides a vacuum insulation panel to which moisture and gas do not easily adsorb while it is being processed or being in storage in an unfinished state. The vacuum insulation panel includes a core provided with air circulation, a getter material which adsorbs moisture and gas from the core, an inner film bag which accommodates the core and the getter material, and an outer barrier bag which accommodates the inner film bag. The getter material is filled in an incision provided on the surface of the core. To prevent the getter material from getting out of the incision, the opening of the incision is narrowed by evacuating air from the interior of the inner film bag and, concurrently, compressing the inner film bag and the core.

Abstract: The invention relates to a vacuum insulation panel which can be used as an insulator for a refrigerator requiring heat insulation to be provided and also to a refrigerator incorporating such a vacuum insulation panel. The invention particularly relates to an arrangement for preventing convection spaces from being formed where an edge of the vacuum insulation panel is folded back. The vacuum insulation panel includes a core which has an inner film bag in which a flexible inorganic fiber laminate is accommodated, and an outer barrier bag which is made of gas-impermeable film such as metallic foil laminated film and which accommodates the core. The inner film bag includes a welded portion and a ventilation portion. The outer barrier bag has a depressurized interior and has been sealed by welding. An edge of the inner film bag is placed in an edge of the outer barrier bag.

Abstract: A vacuum insulating material which minimizes the possibility of absorption of moisture or gas components by its core material during storage in the manufacturing process, improves manufacturing efficiency, and maintains and enhances heat insulation performance. A vacuum insulating material comprises: a core material as an inorganic fiber aggregate; a getter material which absorbs core material gas components; and an envelope with a gas barrier property which encases the core material. The getter material is contained in a housing area made by slitting the core material obliquely with respect to its surface or thickness and the opening of the housing area is narrowed by overlapping.
