Abstract: A storage box includes a wall including: a packaging member; and a heat transfer body and a cold storage agent that are stored in the packaging member. The cold storage agent is disposed closer to an outer surface of the storage box than the heat transfer body is. Consequently, a chill from the cold storage agent spreads over the heat transfer body, and the chill is transferred to an inside of the storage box through the heat transfer body. Thus, a temperature can be more homogeneously maintained in the storage box.

Abstract: A vacuum insulation body includes an outer box (2), an inner box (3), open-cell urethane foam (4) in the insulation space (1b) between the outer box (2) and the inner box (3); and a vacuum outlet (6) in one of the outer box (2) and the inner box (3). The urethane foam (4) includes a through passage (8a) leading to the vacuum outlet (6). The vacuum outlet (6) is sealed after the insulation space (1b) filled with the urethane foam (4) is vacuum-evacuated.

Abstract: A vacuum-sealing device includes external cylinder part (501B) which includes a distal end face that is brought into airtight contact with an outer face of a container that is a vacuum-sealing target to cover an exhaust hole of the container, and includes body part (501A) provided within external cylinder part (501B) and movable forward and backward along an axial center of external cylinder part (501B). The vacuum-sealing device further includes driver (503) that moves external cylinder part (501B) and body part (501A) forward and backward in the direction of extension of the axial center of external cylinder part (501B), and heater (504) that heats distal end portion (51) of body part (501A). Exhaust space (58) communicating with the distal end face of external cylinder part (501B) is formed between an outer circumferential face of distal end portion (51) of body part (501A) and an inner circumferential face of external cylinder part (501B).

Abstract: A vacuum heat insulator according to the present invention includes a core material and an outer packaging material including an inner plate and an outer plate each of which includes a resin sheet. The core material is covered by the outer packaging material. The vacuum heat insulator further includes a heat welded part formed by welding a part of the inner plate and a part of the outer plate. The heat welded part has a recess having a thickness that is 50% or less of an average thickness of the heat welded part. As a result thereof, the adhesion and airtightness of the heat welded part can be maintained, and a highly reliable vacuum heat insulator can be provided.
