Definitions
- the protrusion 54a of the opening member 54 is formed. It is configured to come into contact with the storage container 53 and eventually penetrate the storage container 53. Furthermore, as shown in FIG. 30 and FIG. 31A, the storage container 53 can be held in one of the two parts sandwiching the concavo-convex part that contacts the storage container 53 in a state where no stress is applied to the convex surface.
- a holding portion 54b molded in a U shape is provided.
- the gas adsorbing substance 52 Since the gas adsorbing substance 52 is sealed under reduced pressure in the gas barrier container 53, the gas adsorbing substance 52 does not come into contact with the air even if the gas adsorbing device 51 is left in the atmosphere for a long time. For this reason, the deactivation of the gas adsorbing substance 52 can be suppressed, and can be stored in the atmosphere for a long time. For the same reason, deactivation during production can be suppressed.
- the laminate film covering the core material of the vacuum heat insulating material is flexible, the core material is deformed by the atmospheric pressure applied after sealing under reduced pressure, and compressive force is applied to the gas adsorption device 51.
- the protrusion 54a applies a piercing force to the storage container 53, so that a through hole is formed in the storage container 53, and the gas adsorbing substance 52 in the storage container 53 can adsorb the gas in the laminate film.
- the portions other than the protrusion 54 a of the opening member 54 are made of polypropylene resin and easily deform, so that the protrusion 54 a is pressed against the storage container 53. Since the protrusion 54a is made of metal and has sufficient strength, a through hole is formed in the storage container 53.
- the inside of the storage container 53 communicates with the inside of the laminate film, and the gas in the laminate film can be adsorbed by the gas adsorbing substance 52 in the storage container 53.
- the holding portion 54b that holds the storage container 53 is formed by molding one of the two legs contacting the storage container 53 into a U-shape. It is. Therefore, depending on the variation in the size of at least one of the portion gripped by the holding portion 54b in the storage container 53 and the portion gripping the storage container 53 in the holding portion 54b, and the state of the surface where the holding portion 54b and the storage container 53 contact, The force (frictional force) at which 54b grips the storage container 53 changes.
- the opening member 54 when the opening member 54 is displaced (moved) toward the holding portion 54b, the force (frictional force) with which the holding portion 54b grips the storage container 53 is weakened, and the opening member 54 is displaced (moved) toward the holding portion 54b. If the distance to be operated is large, the holding portion 54b cannot grasp the storage container 53.
- the organic coupling relationship between the opening member 54 and the storage container 53 is poor (the opening member 54 is easily displaced with respect to the storage container 53), and the opening member 54 There was a problem that stable opening of the storage container 53 was difficult.

Since it is difficult to come off, the organic coupling relationship between the opening member and the storage container is strong, and the opening of the storage container by the opening member can be facilitated.
- a gas adsorption device is provided on the outside of the storage container with respect to a gas barrier storage container having an elongated flat cylindrical body in which a gas adsorption substance is sealed under reduced pressure.
- the opening member sandwiches the outer peripheral surface of the cylindrical body in the width direction of the storage container, and at least the protrusion that has entered the storage container among the surfaces opposite to the surface that opens the through hole.
- a holding portion that surrounds the outer peripheral surface of the cylindrical body in the circumferential direction so as to cover a portion that may come into contact with the inside of the storage container, and a fixed end that is connected to the holding portion, and the protrusion at the free end. And formed movable parts.
- the movable portion when the holding container is sandwiched in the width direction by the holding portion, before opening, the movable portion is opposed to the surface on the side where the through hole is opened with a predetermined angle and is opposed to the movable portion. Is pushed with a predetermined force in a direction approaching the surface on the side where the through hole is to be opened, and the protrusion is configured to pierce the surface on the side where the through hole is to be opened.
- the opening member sandwiches the outer peripheral surface of the cylindrical body of the storage container in the width direction of the storage container, and covers at least a part of the surface opposite to the surface that opens the through hole.
- the holding member that surrounds the outer peripheral surface of the cylindrical body in the circumferential direction is provided, the opening member is not easily detached from the storage container, and the opening member and the storage container are easily handled as an integral member. be able to. In other words, even if an external force is applied in any direction of the storage container, the opening member is not easily displaced (is difficult to come off), so the organic coupling relationship between the opening member and the storage container is strong, and the opening member Stable opening of the storage container can be facilitated.
- the opening member there is a possibility that at least the protrusion that has entered the storage container is abutted from the inside of the storage container, of the surface opposite to the surface where the holding portion opens the through hole. Since the portion is covered, there is no possibility that the protrusion of the opening member that has penetrated the storage container may damage other members.
- the opening member sandwiches the storage container in the width direction and surrounds the outer peripheral surface of the storage container in the circumferential direction so as to cover at least a part of the surface opposite to the surface that opens the through hole.
- the opening member can be configured by bending a flat plate that can be elastically deformed and bent with one end being a free end, the opening member can be manufactured at low cost, By using the opening member that can be manufactured at a low cost, the manufacturing cost of the gas adsorption device can be reduced.
- the gas adsorbing device of the present invention can easily handle the opening member and the storage container as an integral member, and it is difficult to cause variations in the magnitude of external force required for opening.
- the possibility that the gas adsorbing device is opened by pushing the opening member is small, and the occurrence of the problem that the protrusion cannot open the through-hole in the storage container despite the predetermined displacement of the movable part can be reduced.
- the protrusion has a gap between an edge of a through hole formed by the protrusion entering the storage container and the protrusion. It has a shape that creates a gap that can adsorb the gas around the storage container with a gas adsorbing substance.
- a gas adsorption device is a gas adsorbent material and a substantially flat cylindrical shape having an opening at one end in the longitudinal direction, and the gas adsorbent material
