Description

本発明は、窒素および酸素を吸着可能とした気体吸着デバイスを搭載した真空断熱材において、真空断熱材の信頼性向上に関するものである。 TECHNICAL FIELD The present invention relates to improving the reliability of a vacuum heat insulating material equipped with a gas adsorption device capable of adsorbing nitrogen and oxygen.

近年、高真空を用いた断熱材への需要が高まりつつある。 In recent years, the demand for heat insulating materials using high vacuum is increasing.

家庭用電化製品については、特に冷蔵庫、冷凍庫、自動販売機などの保温保冷機器において、熱損失を低減させるために、優れた断熱性能を有する断熱材が求められている。 BACKGROUND ART For household electrical appliances, particularly in heat and cold storage equipment such as refrigerators, freezers, and vending machines, there is a demand for heat insulating materials having excellent heat insulating performance in order to reduce heat loss.

近年では、家庭用電化製品に限らず、住宅などにおいても、電気、ガスなどのエネルギ消費量を低減させるため、断熱性能のすぐれた断熱材が求められている。 In recent years, in order to reduce the consumption of energy such as electricity and gas, a heat insulating material with excellent heat insulating performance is required not only for household electric appliances but also for houses and the like.

断熱材には、一般的にグラスウールやウレタンフォームなどが主に用いられている。しかし、これらの断熱材の断熱性能を向上させるためには断熱材の厚さを増す必要がある。断熱材を充填できる空間に制限がある場合や、省スペースや空間の有効利用が求められる場合においては、適用できない。 Glass wool and urethane foam are generally used as heat insulating materials. However, in order to improve the insulation performance of these heat insulating materials, it is necessary to increase the thickness of the heat insulating materials. This method cannot be applied when there is a limit to the space that can be filled with heat insulating material, or when space saving or effective use of space is required.

そこで、上記課題を解決する高性能な断熱材として、真空断熱材が提案されている。これはスペーサーの役割を持つ芯材を、ガスバリア性を有する外被材中に挿入し、内部を減圧して封止した断熱体である。 Therefore, a vacuum heat insulating material has been proposed as a high-performance heat insulating material that solves the above problems. This is a heat insulator in which a core material serving as a spacer is inserted into an outer covering material having gas barrier properties, and the inside is depressurized and sealed.

真空断熱材は、内部が真空であるために、高い断熱性を有するが、内部の真空度の低下によって、性能が大きく変化する。 The vacuum heat insulating material has a high heat insulating property because the inside is vacuum, but the performance changes greatly due to the decrease in the degree of the inside vacuum.

外被材内部の真空度が低下する主な要因は、生産時に外被材中に残留した窒素、酸素および水分を中心とする気体や、時間とともに外被材を通過して内部に侵入する気体である。 The main factors that reduce the degree of vacuum inside the outer covering material are gases, mainly nitrogen, oxygen, and moisture, that remain in the outer covering material during production, and gases that pass through the outer covering material and enter the interior over time. is.

これらの気体のうち、水分を吸着するために、水分吸着材を真空断熱材の外被材内部に、芯材とともに挿入する方法が考案されている。 In order to adsorb moisture among these gases, a method has been devised in which a moisture adsorbent is inserted into the outer covering material of the vacuum heat insulating material together with the core material.

窒素や酸素等の水分以外の成分を吸着するために、窒素、酸素、水分を吸着可能な気体吸着デバイスを、真空断熱材の外被材内部に、芯材とともに挿入する方法が考案されている。気体吸着デバイスは、通常、難気体透過性の容器の内部に、ゼオライト等の気体吸着物質を減圧密封したものが使われる。気体吸着デバイスを、真空断熱材の外被材内部に、芯材とともに挿入した後、気体吸着物質を覆う難気体透過性の容器の一部を破壊し、真空断熱材の外被材内部の気体を、気体吸着物質に吸着させる事で、真空断熱材内部の真空度を低く維持する事が可能になる。破壊方法には、容器の一部の材質を脆性物質とし、この脆性物質に荷重を加え、変形させることによって破壊し、上記容器に開口を作る方法が考案されている（特許文献１）
他にも、気体吸着デバイスを構成する難気体透過性の容器へ、突起部を有する開封部材を取り付け、開封部材に荷重を加えることによって、突起部が容器に開口を作る方法が考案されている（特許文献２） In order to adsorb components other than moisture such as nitrogen and oxygen, a method has been devised in which a gas adsorption device capable of adsorbing nitrogen, oxygen and moisture is inserted into the outer covering material of the vacuum insulation material together with the core material. . As a gas adsorption device, a gas-adsorbing substance such as zeolite, etc., is sealed under reduced pressure inside a gas-poorly permeable container. After inserting the gas adsorption device into the outer covering material of the vacuum insulation material together with the core material, a part of the gas-impermeable container that covers the gas adsorption material is broken, and the gas inside the outer covering material of the vacuum insulation material is removed. is adsorbed on the gas-adsorbing substance, it is possible to keep the degree of vacuum inside the vacuum heat insulating material low. As a breaking method, a method has been devised in which a part of the container is made of a brittle material, and a load is applied to the brittle material to deform it to break it, thereby creating an opening in the container (Patent Document 1).
In addition, a method has been devised in which an opening member having protrusions is attached to a gas-impermeable container constituting a gas adsorption device, and a load is applied to the opening member so that the protrusions form an opening in the container. (Patent document 2)

しかしながら、特許文献１に記載の構成では、脆性物質が破壊される際、脆性物質が粉化し、粉化した脆性物質が開口を閉塞する可能性があり、その場合、真空断熱材外被材内部と、気体吸着物質の間に、大きな通気抵抗が生まれ、気体吸着デバイスに必要な気体吸着速度（ｍｏｌ／ｓ）および吸着量（ｍｏｌ／個）が得られなくなる課題がある。 However, in the configuration described in Patent Document 1, when the brittle substance is destroyed, the brittle substance may be pulverized and the pulverized brittle substance may block the opening. , a large ventilation resistance is generated between the gas adsorption substances, and there is a problem that the gas adsorption speed (mol/s) and the adsorption amount (mol/piece) required for the gas adsorption device cannot be obtained.

逆に脆性物質が破壊される際、大きな亀裂が形成され、真空断熱材外被材内部と気体吸着物質の間の通気抵抗が少なくなる場合も考えられ、その場合は、生産時に真空断熱材の外被材中に残留した水分や、時間とともに外被材を通過して外被材内部に侵入する水分を、気体吸着デバイスと共に真空断熱材中に挿入される水分吸着材よりも、気体吸着デバイスが優先的に吸着してしまい、気体吸着デバイスが窒素や酸素などの成分を十分に吸着しなくなる課題がある。 Conversely, when the brittle material is destroyed, a large crack may be formed and the ventilation resistance between the inside of the vacuum insulation material and the gas adsorbing material may decrease. Moisture remaining in the outer covering material and moisture passing through the outer covering material over time and entering the outer covering material are removed by the gas adsorption device rather than the moisture adsorbent inserted into the vacuum insulation material together with the gas adsorption device. is preferentially adsorbed, and the gas adsorption device does not sufficiently adsorb components such as nitrogen and oxygen.

他にも、真空断熱材の成型工程や、真空断熱材に常に加わる大気圧による荷重で、脆性物質が容易に破壊され、真空断熱材の生産時に外被材中に残留した水分を、気体吸着デバイスと共に真空断熱材中に挿入される水分吸着材よりも、気体吸着デバイスが優先的に吸着してしまい、気体吸着デバイスが窒素や酸素などの成分を十分に吸着しなくなる課題がある。 In addition, the molding process of the vacuum insulation material and the load caused by the atmospheric pressure that is constantly applied to the vacuum insulation material easily destroys brittle substances, and the moisture remaining in the outer covering material during the production of the vacuum insulation material is absorbed by the gas. There is a problem that the gas adsorption device preferentially adsorbs components such as nitrogen and oxygen over the moisture adsorbent inserted into the vacuum heat insulating material together with the device, and the gas adsorption device does not sufficiently adsorb components such as nitrogen and oxygen.

また、脆性物質の破壊を確認する方法として、破壊時に発生するかすかな音波を確認するなどが考えられるが、音波が小さいため、この確認は困難を伴う。 As a method for confirming the breakage of a brittle material, it is conceivable to confirm a faint sound wave generated at the time of breakage, but this confirmation is difficult because the sound wave is small.

また特許文献２に記載の構成では、突起部を有する開封部材により、気体吸着デバイスの容器に開口を形成するが、開口を形成する面に対し、突起部が垂直に近い形で配置されるため、気体吸着デバイスの総厚さが大きくなるという課題を有している。このことは、搭載する真空断熱材を薄くしたり、平滑にしたりできない事になり、真空断熱材が搭載される製品の設計および断熱性能の大きな制約になる。 Further, in the configuration described in Patent Document 2, an opening is formed in the container of the gas adsorption device by an unsealing member having a projection. , the problem is that the total thickness of the gas adsorption device increases. This means that the vacuum heat insulating material to be mounted cannot be made thin or smooth, and this greatly limits the design and heat insulation performance of the product on which the vacuum heat insulating material is mounted.

真空断熱材が平滑にならず、表面に起伏ができる事は、この起伏部分にこすれ等のストレスが集中的に加わり、真空断熱材の外被材が破損し易い課題がある。 If the surface of the vacuum insulation material is not smooth and has undulations, stress such as rubbing is applied intensively to the undulations, causing the problem that the outer covering material of the vacuum insulation material is easily damaged.

他にも、保管等で真空断熱材を積み上げた場合、上記起伏に荷重が集中し、意図しないタイミングで突起部が気体吸着デバイスの容器に開口が形成され、真空断熱材の生産時に外被材中に残留した水分を、気体吸着デバイスと共に真空断熱材中に挿入される水分吸着材よりも、気体吸着デバイスが優先的に吸着してしまい、気体吸着デバイスが窒素や酸素などの成分を十分に吸着しなくなる課題がある。 In addition, when vacuum insulation materials are piled up for storage, etc., the load is concentrated on the undulations, and the protrusions form openings in the container of the gas adsorption device at an unintended timing. The moisture remaining inside is preferentially adsorbed by the gas adsorption device over the moisture adsorption material inserted into the vacuum insulation material together with the gas adsorption device, and the gas adsorption device sufficiently removes components such as nitrogen and oxygen. There is a problem that it will not be adsorbed.

また、開封部材は気体吸着デバイスの容器に取り付けられているため、開封部材が真空断熱材の生産時に外れ、もしくは開封部材の位置が変わり、気体吸着デバイスの容器に開口を作れない可能性があり、課題である。 In addition, since the opening member is attached to the container of the gas adsorption device, there is a possibility that the opening member may come off during production of the vacuum insulation material, or the position of the opening member may change, making it impossible to form an opening in the container of the gas adsorption device. , is a problem.

さらに、開封部材は気体吸着デバイスの容器に取り付けられているため、気体吸着デバイスの真空断熱材への挿入時や、気体吸着デバイスを有する真空断熱材の保管中に、開封部材が真空断熱材の外被材に接触し、外被材の破損に繋がる課題がある。 Furthermore, since the opening member is attached to the container of the gas adsorption device, the opening member may be attached to the vacuum insulation material when the gas adsorption device is inserted into the vacuum insulation material or during storage of the vacuum insulation material having the gas adsorption device. There is a problem that it comes into contact with the outer covering material and leads to breakage of the outer covering material.

本発明は、上記課題を解決するものであり、少なくとも気体難透過性素材の軟包材で構成された容器と、気体吸着材と、前記容器に開口をつくる開封部材から構成される気体吸着デバイスであって、前記開封部材は、前記容器に開口を作る突起部を有し、開封部材は前記容器の内側にあり、前記突起部は、開口を作る面に対して水平な方向に配置されており、開封部材に荷重が加えられた際に、開封部材周辺の容器が変形し、突起物が有する突起部が容器と接触し、突起部が容器に開口を作ることを特徴とする、気体吸着デバイスである。 The present invention solves the above-mentioned problems, and is a gas adsorption device comprising a container composed of at least a soft packaging material made of a gas-impermeable material, a gas adsorbent, and an unsealing member forming an opening in the container. wherein the opening member has a protrusion that creates an opening in the container, the opening member is inside the container, and the protrusion is arranged in a horizontal direction with respect to the plane that creates the opening. When a load is applied to the unsealing member, the container around the unsealing member is deformed, the protrusions of the protrusions come into contact with the container, and the protrusions form openings in the container. Device.

通常、開封部材が有する突起部は開口を作る面に対して垂直もしくは角度を持って垂直に近い位置関係とされるが、このことが気体吸着デバイスの総厚さを大きくしている。 Normally, the protrusions of the opening member are positioned perpendicular to the plane of the opening, or nearly perpendicular to the plane at an angle, which increases the total thickness of the gas adsorption device.

この位置関係を、開口を作る面に対して垂直ではなく、水平に近い位置関係とした場合、開口を作るように突起部を稼動させる開封部財の稼動部が複雑になり、気体吸着デバイスの総厚さは同じか、それ以上になり、現実的ではない。 If this positional relationship is not perpendicular to the plane on which the opening is to be made, but is close to horizontal, the operating part of the opening part that moves the projection to make the opening will become complicated, and the gas adsorption device will not work properly. The total thickness will be the same or greater, which is impractical.

そのため、開口を作る突起部は水平とし、稼動部は無い、もしくは殆ど稼動しない形態とする必要があるが、気体吸着デバイスの容器を変形可能にする事で、突起部が容器に接触し、開口を作る事が可能になる。 Therefore, it is necessary to make the protrusions that form the openings horizontal and have no moving parts or a form that hardly moves. It becomes possible to make

外被材に直接開口を作るため、脆性物質を破壊する特許文献１に記載の方法のように、気体吸着デバイスの気体吸着速度が低くなりすぎることは無く、たとえばフィルターなど、気体吸着速度を調整する機構を気体吸着デバイスの容器の内部に設けることで、気体吸着デバイスの気体吸着速度の調整が容易になる。 Since the opening is directly formed in the outer covering material, the gas adsorption speed of the gas adsorption device does not become too low unlike the method described in Patent Document 1, which destroys the brittle substance. By providing the mechanism inside the container of the gas adsorption device, the gas adsorption speed of the gas adsorption device can be easily adjusted.

開封部材が有する突起部は、気体吸着デバイスの容器に対して水平に配置され、開口を作るために容器を変形させる必要があるため、開口を作るために加える荷重は、気体吸着デバイスの開封部材に集中的に加える必要があるため、大気圧や真空断熱材の成型時に意図せず開口が作られる可能性を大幅に低減できる。 The projections of the unsealing member are arranged horizontally with respect to the container of the gas adsorption device, and the container must be deformed to form the opening. Since it is necessary to concentrate on the pressure, it is possible to greatly reduce the possibility of unintentionally creating openings during molding of atmospheric pressure and vacuum insulation materials.

また開封部材が有する突起部は、気体吸着デバイスの容器に対して水平に配置されるため、気体吸着デバイスの総厚さは、特許文献２に記載の方法に比べ薄くする事が可能になり、真空断熱材の平滑性向上および真空断熱材の外被材の破壊リスク低減に繋がる。 In addition, since the projections of the opening member are arranged horizontally with respect to the container of the gas adsorption device, the total thickness of the gas adsorption device can be made thinner than the method described in Patent Document 2. This leads to an improvement in the smoothness of the vacuum insulation material and a reduction in the risk of breakage of the outer covering material of the vacuum insulation material.

さらに、この構成によれば、開封部材は気体吸着デバイスの容器の外側ではなく、容器の内部に配置する事が可能になるため、断熱材の生産時に外れたり、開封部材の位置が変わったりする事が無くなる。また気体吸着デバイスの真空断熱材への挿入時や、気体吸着デバイスを有する真空断熱材の保管中に、開封部材が真空断熱材の外被材に接触し、外被材を破損させるリスクを大幅に低減できる。更に真空断熱材を廃棄する際には、気体吸着デバイスを容器ごと容易に分別することができる。 Furthermore, according to this configuration, the opening member can be placed inside the container of the gas adsorption device, not outside the container. things will go away. In addition, when inserting the gas adsorption device into the vacuum insulation material or during storage of the vacuum insulation material with the gas adsorption device, the opening member comes into contact with the outer covering material of the vacuum insulation material, greatly reducing the risk of damaging the outer covering material. can be reduced to Furthermore, when discarding the vacuum insulation material, the gas adsorption device can be easily sorted together with the container.

本発明により、真空断熱材中の気体吸着デバイスに形成する開口を安定化でき、気体吸着デバイスの気体吸着速度の安定化が容易になり、それに伴い気体吸着量の安定化が容易になる。 According to the present invention, the openings formed in the gas adsorption device in the vacuum heat insulating material can be stabilized, the gas adsorption speed of the gas adsorption device can be stabilized, and accordingly the gas adsorption amount can be easily stabilized.

また、気体吸着デバイスの開封部材に集中的に荷重を加えなければ気体吸着デバイスの容器に開口が作られないため、意図しないタイミングで開口が作られる可能性が大幅に低減され、気体吸着デバイスの気体吸着量の安定化が容易になる。 In addition, since the container of the gas adsorption device does not open unless a concentrated load is applied to the unsealing member of the gas adsorption device, the possibility of opening at an unintended timing is greatly reduced. It becomes easy to stabilize the gas adsorption amount.

また、気体吸着デバイスの総厚さを薄くする事ができ、気体吸着デバイスが搭載された真空断熱材の平面性の向上と、真空断熱材の外被材の破壊リスクを低減できる。 In addition, the total thickness of the gas adsorption device can be reduced, the flatness of the vacuum insulation material on which the gas adsorption device is mounted can be improved, and the risk of breakage of the outer covering material of the vacuum insulation material can be reduced.

さらに、開封部材を気体吸着デバイスの容器の内部に配置する事が可能になり、開封部材の外れや取り付け位置の変化を防止でき、気体吸着デバイスに確実に開口を作り、気体吸着デバイスの気体吸着量の安定化が可能になる。 Furthermore, it is possible to arrange the opening member inside the container of the gas adsorption device, thereby preventing the removal of the opening member and the change of the mounting position, surely creating an opening in the gas adsorption device, and allowing the gas adsorption device to adsorb the gas. volume stabilization is possible.

以下、図表を参照しながら、本発明の実施の形態について説明する。
（第１実施の形態）
図１は、本発明の第１実施の形態における気体吸着剤の概略図である。 BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 is a schematic diagram of a gas adsorbent according to a first embodiment of the invention.

図１に示すように、本実施の気体吸着デバイス１は、気体難透過性素材の軟包材からなる気体難透過性素材の軟包材からなる容器２と、気体吸着剤３と、前記容器に開口を作る開封部材４から構成されている。 As shown in FIG. 1, the gas adsorption device 1 of this embodiment includes a container 2 made of a flexible packaging material made of a material with low gas permeability, a gas adsorbent 3, and the container It consists of an opening member 4 which creates an opening in the.

開封部材４は、気体難透過性素材の軟包材からなる容器２に開口を作る突起部５を有する。 The unsealing member 4 has a protrusion 5 that forms an opening in the container 2 made of a soft packaging material that is impermeable to gas.

また開封部材４は気体難透過性素材の軟包材からなる容器２の内側に配置される。 The unsealing member 4 is placed inside the container 2 made of a soft packaging material that is impermeable to gas.

突起部５は、開口を作る面に対して水平な方向に配置されており、開封部材４に荷重が加えられた際に、開封部材４周辺の気体難透過性素材の軟包材からなる容器２が変形し、開封部材４が有する突起部５が気体難透過性素材の軟包材からなる容器２と接触し、突起部５が気体難透過性素材の軟包材からなる容器２に開口を作る。 The projecting portion 5 is arranged in a horizontal direction with respect to the surface forming the opening, and when a load is applied to the opening member 4, the container made of a soft packaging material made of a gas impermeable material around the opening member 4 2 is deformed, the protrusion 5 of the unsealing member 4 comes into contact with the container 2 made of the flexible packaging material of the gas-impermeable material, and the protrusion 5 opens in the container 2 of the flexible packaging material of the gas-impermeable material. make.

上記構成のように、開封部材４は気体難透過性素材の軟包材からなる容器２に対して水平に配置され、なおかつ開封部材４は突起部５の位置を気体難透過性素材の軟包材からなる容器２に開口を作るために移動するための稼動部を有しないため、気体吸着デバイス１の総厚さを薄くできる。 As in the above configuration, the unsealing member 4 is arranged horizontally with respect to the container 2 made of the soft packaging material of the gas-impermeable material, and the protrusions 5 of the opening member 4 are positioned in the flexible packaging of the gas-impermeable material. The total thickness of the gas adsorption device 1 can be reduced because the container 2 made of material does not have a moving part for making an opening.

また突起部５を含む開封部材４は、気体難透過性素材の軟包材からなる容器２の内側に配置されているため、気体吸着デバイスを真空断熱材の外被材の内側に挿入する場合に、真空断熱材の外被材を傷つけるリスクを低減できる。 In addition, since the opening member 4 including the projecting portion 5 is arranged inside the container 2 made of a soft packaging material that is impermeable to gas, when the gas adsorption device is inserted inside the jacket material of the vacuum insulation material, In addition, the risk of damaging the outer covering material of the vacuum insulation material can be reduced.

このことは、気体吸着デバイスを搭載した真空断熱材の保管中および使用中に、真空断熱材の外被材を傷つけるリスクも低減できる事を意味する。 This means that the risk of damage to the outer covering material of the vacuum insulation material can be reduced during storage and use of the vacuum insulation material equipped with the gas adsorption device.

さらに、開封部材４および突起部５が、気体吸着デバイスの真空断熱材への挿入時や、真空断熱材へ挿入された後、気体吸着デバイスから外れる可能性をほぼ無くす事が可能になる。 Furthermore, it is possible to substantially eliminate the possibility that the unsealing member 4 and the protruding part 5 will come off the gas adsorption device when the gas adsorption device is inserted into the vacuum insulation material or after being inserted into the vacuum insulation material.

気体吸着デバイスの内部は大気圧および真空断熱材の外被材の内側の圧力よりも低くなっているため、気体難透過性素材の軟包材からなる気体難透過性素材の軟包材からなる容器２は、気体吸着デバイス１の内外の圧力差により、気体難透過性素材の軟包材からなる容器２の内側に向かって変形し、気体難透過性素材の軟包材からなる容器２により開封部材４および突起部５が強く固定されるため、気体難透過性素材の軟包材からなる容器２内部で、開封部材４および突起部５が移動する可能性を大幅に低減できる。 Since the inside of the gas adsorption device is at a pressure lower than the atmospheric pressure and the pressure inside the outer covering material of the vacuum heat insulating material, it is made of a flexible packaging material of a gas-impermeable material. Due to the pressure difference between the inside and outside of the gas adsorption device 1, the container 2 is deformed toward the inside of the container 2 made of the soft packaging material of the gas-impermeable material. Since the unsealing member 4 and the protrusions 5 are strongly fixed, the possibility of the unsealing member 4 and the protrusions 5 moving inside the container 2 made of the soft packaging material of the gas-impermeable material can be greatly reduced.

気体難透過性素材の軟包材からなる容器２の内外の圧力差により加わる荷重は気体難透過性素材の軟包材からなる容器２に対して垂直なので、気体難透過性素材の軟包材からなる容器２に水平に固定された開封部材４および突起部５は、気体難透過性素材の軟包材からなる容器２に開口９を形成するだけの荷重を気体難透過性素材の軟包材からなる容器２に加えない。 Since the load applied by the pressure difference between the inside and outside of the container 2 made of the soft packaging material of gas-impermeable material is perpendicular to the container 2 made of the flexible packaging material of the gas-impermeable material, the flexible packaging material is made of the gas-impermeable material. The unsealing member 4 and the projecting portion 5 which are horizontally fixed to the container 2 made of gas-impermeable material apply a load sufficient to form the opening 9 in the container 2 made of the soft-packaging material of the gas-impermeable material. Do not add to container 2 made of material.

図１に示す開封部材４は円柱状であるが、板状や、円柱および板状の部材が湾曲した形状であっても同様の効果が得られる。 Although the unsealing member 4 shown in FIG. 1 has a cylindrical shape, the same effect can be obtained even if the opening member 4 has a plate shape or a shape in which the column and the plate-like members are curved.

図１に示す突起部５は、先端が鋭利な形状になっているが、実際には気体難透過性素材の軟包材からなる気体難透過性素材の軟包材からなる容器２に、開口が形成されるだけの荷重を加えられる範囲で、球形など、その他の形状でもよい。 The projecting portion 5 shown in FIG. 1 has a sharp tip. Other shapes, such as spheres, may be used as long as they are loaded enough to form a .

図２は、上記図１に記載の気体吸着デバイス１搭載した真空断熱材の断面の概略図である。図２に記載の真空断熱材の断面の概略図は、開封部材４が有する突起部５により、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９が形成された後の状態を示している。 FIG. 2 is a schematic cross-sectional view of a vacuum heat insulating material on which the gas adsorption device 1 shown in FIG. 1 is mounted. In the schematic diagram of the cross-section of the vacuum heat insulating material shown in FIG. It shows the after state.

図２に示すように、真空断熱材６は、芯材７および気体吸着デバイス１を、気体難透過性素材からなる気体難透過性素材からなる外被材８で覆い、気体難透過性素材からなる外被材８の内側の圧力が、大気圧よりも低い圧力に減圧されたものであり、気体吸着デバイス１が有する開封部材４に集中的に力が加えられることにより、気体難透過性素材の軟包材からなる容器２が変形し、開封部材４が有する突起部５が気体難透過性素材の軟包材からなる容器２と接触し、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２の内部と、真空断熱材６の気体難透過性素材からなる外被材８内部の空間を連結する開口９を形成している。 As shown in FIG. 2, the vacuum heat insulating material 6 covers the core material 7 and the gas adsorption device 1 with a jacket material 8 made of a gas-impermeable material. The pressure inside the outer covering material 8 is reduced to a pressure lower than the atmospheric pressure, and by applying a concentrated force to the opening member 4 of the gas adsorption device 1, the gas impermeable material The container 2 made of the flexible packaging material is deformed, the protrusion 5 of the opening member 4 comes into contact with the container 2 made of the soft packaging material of the gas-impermeable material, and the gas-impermeable material of the gas adsorption device 1 is softened. An opening 9 is formed to connect the inside of the container 2 made of the packaging material and the space inside the outer covering material 8 made of the gas impermeable material of the vacuum heat insulating material 6 .

上記開封部材４に集中的に加えられた荷重により、芯材７が変形し、真空断熱材６の表面の、前記荷重が加えられた位置に凹部１０が形成される。 Due to the concentrated load applied to the opening member 4, the core material 7 is deformed, and a concave portion 10 is formed on the surface of the vacuum heat insulating material 6 at the position where the load is applied.

図２には、凹部１０を記載しているが、芯材７が復元性の高い材料の場合には凹部１０は存在せず、この有無が及ぼす本発明への影響は無い。 Although the recess 10 is shown in FIG. 2, the recess 10 does not exist when the core material 7 is made of a highly restorable material, and the presence or absence of this does not affect the present invention.

より好ましくは、気体難透過性素材の軟包材からなる容器２が変形した際、突起部５が気体難透過性素材の軟包材からなる容器２に強い荷重が加えるよう、開封部材４もしくは突起部５は、気体難透過性素材の軟包材からなる容器２に比べ高いヤング率である事が好ましい。 More preferably, the opening member 4 or It is preferable that the protrusion 5 has a higher Young's modulus than the container 2 made of a soft packaging material that is impermeable to gas.

残留水分による真空断熱材６の気体難透過性素材からなる外被材８の内部の真空度の低下を低減するため、真空断熱材６の気体難透過性素材からなる外被材８の内部に、水分吸着材（図に記載無し）を気体吸着デバイス１とあわせて挿入しても良い。 In order to reduce the reduction in the degree of vacuum inside the outer covering material 8 made of the gas-impermeable material of the vacuum heat insulating material 6 due to residual moisture, , a moisture adsorbent (not shown in the figure) may be inserted together with the gas adsorption device 1 .

図２に示す開口９は、気体分子に対して十分に大きければよく、例えばわずかな亀裂など、目視可能な明確な貫通孔でなくとも良い。
（実施例１）
次に、第１実施の形態における気体吸着デバイス１および気体吸着デバイス１を搭載した真空断熱材６の実施例１について説明する。 The openings 9 shown in FIG. 2 need only be sufficiently large for the gas molecules and need not be clear visible through-holes, for example slight cracks.
(Example 1)
Next, Example 1 of the gas adsorption device 1 according to the first embodiment and the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted will be described.

まず、使用した気体吸着デバイス１について説明する。 First, the used gas adsorption device 1 will be described.

気体吸着デバイス１の気体難透過性素材の軟包材からなる気体難透過性素材の軟包材からなる容器２として、アルミニウムを蒸着したＰＥＴ層と、アルミニウム層と、低密度ポリエチレン層からなる複層材料を用いた。アルミニウムを蒸着したＰＥＴ層の厚さは１２μｍ、アルミニウム層の厚さは６μｍ、低密度ポリエチレン層の厚さは５０μｍとした。上記複層フィルムの２枚を、低密度ポリエチレン層同士を対向させて配置し、周辺部を加熱して溶着することで袋状にし、気体難透過性素材の軟包材からなる容器２を形成した。 As a container 2 made of a flexible packaging material made of a gas-impermeable material for the gas adsorption device 1, a composite made of a PET layer deposited with aluminum, an aluminum layer, and a low-density polyethylene layer was used. A layer material was used. The thickness of the PET layer deposited with aluminum was 12 μm, the thickness of the aluminum layer was 6 μm, and the thickness of the low-density polyethylene layer was 50 μm. Two of the multi-layered films are arranged so that the low-density polyethylene layers face each other, and the peripheral portion is heated and welded to form a bag shape, forming a container 2 made of a flexible packaging material made of a gas-impermeable material. did.

気体難透過性素材の軟包材からなる容器２の寸法は、短辺の長さを４５ｍｍ、長辺の長さを１１０ｍｍとした。 As for the dimensions of the container 2 made of the soft packaging material of gas-impermeable material, the length of the short side was 45 mm and the length of the long side was 110 mm.

この複層材料の気体透過速度（酸素）は、１ｃｃ／（日・ｍ２・ＭＰａ）以下であった。 The gas permeation rate (oxygen) of this multilayer material was 1 cc/(day·m 2 ·MPa) or less.

開口９が形成されていない状態では、気体難透過性素材の軟包材からなる容器２の内部に封入された気体吸着剤３が、気体吸着デバイス１周辺のガスを吸着することはなく、気体吸着能力は封入時の能力を維持した。 In the state where the opening 9 is not formed, the gas adsorbent 3 sealed inside the container 2 made of a soft packaging material of gas-impermeable material does not adsorb the gas around the gas adsorption device 1, and the gas Adsorption capacity was maintained at the time of encapsulation.

本実施例では、上記樹脂とアルミニウム箔から成る複層フィルムを用いたが、ガスバリア性があり、荷重に対し変形し易ければその他の材質でも良い。 In this embodiment, a multilayer film composed of the above resin and aluminum foil was used, but other materials may be used as long as they have gas barrier properties and are easily deformed under load.

気体吸着剤３には、ＺＳＭ－５型のゼオライトを用いた。あらかじめ真空中で加熱することで吸着ガスを脱ガスし、気体が吸着できるようにしたものを用いた。 ZSM-5 type zeolite was used as the gas adsorbent 3 . The adsorbed gas was degassed by heating in advance in a vacuum, and the adsorbed gas was used.

開封部材４は、材質がステンレスの、円柱形状のものを用いた。直径は１ｍｍとした。 The unsealing member 4 was made of stainless steel and had a cylindrical shape. The diameter was 1 mm.

突起部５は、開封部材４の円柱の一端のＲを１ｍｍに加工して形成した。 The projecting portion 5 was formed by processing one end of the cylinder of the unsealing member 4 to have a radius of 1 mm.

突起部５を含む開封部材４は、気体難透過性素材の軟包材からなる容器２の短辺側一辺と、長辺側二辺の３方を熱溶着して袋状にした後、気体難透過性素材の軟包材からなる容器２の短辺側に、短辺と平行になるように配置した。 The unsealing member 4 including the projecting portion 5 is formed by heat-welding one short side and two long sides of the container 2 made of a soft packaging material made of a gas-impermeable material to form a bag. It was arranged on the short side of a container 2 made of a soft packaging material made of a low-permeability material so as to be parallel to the short side.

その後、上記予め脱ガスした気体吸着剤３を、アルゴン雰囲気にて気体難透過性素材の軟包材からなる容器２に充填し、再度真空雰囲気にしたうえで、気体難透過性素材の軟包材からなる容器２の、溶着していない短辺側一辺を熱溶着し、封止した。 After that, the gas adsorbent 3 degassed in advance is filled in the container 2 made of a soft packaging material of gas-impermeable material in an argon atmosphere, and the vacuum atmosphere is again made, and then the soft packaging of the gas-impermeable material is performed. The non-welded short side of the container 2 made of material was thermally welded and sealed.

気体難透過性素材の軟包材からなる容器２への気体吸着剤３の充填重量は、０．５ｇとした。この気体吸着剤３の１０Ｐａでの気体吸着能力は４ｃｃ／ｇであった。 The filling weight of the gas adsorbent 3 in the container 2 made of a soft packaging material of gas-impermeable material was 0.5 g. The gas adsorption capacity of this gas adsorbent 3 at 10 Pa was 4 cc/g.

気体難透過性素材の軟包材からなる容器２のヤング率は開封部材４に比べ低いため、開封部材４の一部に集中的に荷重を加えることで、開封部材４以上に気体難透過性素材の軟包材からなる容器２が大きく変形し、開封部材４の突起部５が、気体難透過性素材の軟包材からなる容器２に接触し、開口９が作られる。 Since the Young's modulus of the container 2 made of a soft packaging material made of a gas-impermeable material is lower than that of the unsealing member 4, by applying a concentrated load to a part of the unsealing member 4, the gas-impermeability can be improved more than that of the unsealing member 4. The container 2 made of the flexible packaging material is greatly deformed, and the protrusion 5 of the opening member 4 comes into contact with the container 2 made of the flexible packaging material of gas-impermeable material, and an opening 9 is formed.

このことにより、気体吸着デバイス１の内外の雰囲気が連通し、気体吸着デバイス１の周辺の気体を吸着できるようになる。 As a result, the atmosphere inside and outside the gas adsorption device 1 communicates, and the gas around the gas adsorption device 1 can be adsorbed.

次に、上記気体吸着デバイス１を搭載した、真空断熱材６について説明する。 Next, the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted will be described.

真空断熱材６の芯材７には、グラスウールを用いた。芯材７のサイズは幅２５０ｍｍ、長さ３２０ｍｍであり、重量は２０２ｇとした。 Glass wool was used for the core material 7 of the vacuum heat insulating material 6 . The core material 7 had a width of 250 mm, a length of 320 mm, and a weight of 202 g.

外装材には、１５μｍのナイロン層と、２５μｍのナイロン層と、６μｍのアルミニウム層と、５０μｍの低密度ポリエチレン層を重ねた複合フィルムを用いた。 A composite film in which a 15 μm nylon layer, a 25 μm nylon layer, a 6 μm aluminum layer, and a 50 μm low-density polyethylene layer were laminated was used as the exterior material.

本実施例では、上記樹脂とアルミニウム箔から成る複層フィルムを用いたが、ガスバリア性があれば、その他の材質でも良い。 In this example, a multilayer film made of the above resin and aluminum foil was used, but other materials may be used as long as they have gas barrier properties.

上記フィルム二枚を、低密度ポリエチレン層同士を対向させ、周縁部を熱溶着することで袋状に形成した。 The two films described above were formed into a bag shape by placing the low-density polyethylene layers facing each other and heat-sealing the peripheral edges.

気体吸着デバイス１は、開口９が作られていない状態で芯材７の内部に配置し、気体難透過性素材からなる外被材８中に芯材７とともに挿入した。 The gas adsorption device 1 was placed inside the core material 7 without the opening 9, and inserted together with the core material 7 into the outer covering material 8 made of a gas impermeable material.

真空断熱材６の気体難透過性素材からなる外被材８の内部を減圧し、熱伝導率を３．５ｍＷ／ｍ・Ｋにした。 The inside of the outer covering material 8 made of the gas-impermeable material of the vacuum heat insulating material 6 was decompressed to set the thermal conductivity to 3.5 mW/m·K.

その後、上記気体吸着デバイス１を搭載した真空断熱材６について、真空断熱材６の気体難透過性素材からなる外被材８の外側から、気体吸着デバイス１の開封部材４の一部に集中的に荷重を加えた。 After that, the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted is concentrated on a part of the opening member 4 of the gas adsorption device 1 from the outside of the outer covering material 8 made of a gas impermeable material of the vacuum heat insulating material 6. was loaded.

荷重を加えるために使用した設備は、プレス機にφ１０ｍｍのウレタン製の治具を固定したものを使用した。 The equipment used for applying the load was a pressing machine to which a urethane jig of φ10 mm was fixed.

上記プレス機により、開封部材４に、気体難透過性素材からなる外被材８の外側から２０ｋｇｆの力を加えた。 A force of 20 kgf was applied to the unsealing member 4 from the outside of the covering member 8 made of a gas impermeable material by the press machine.

その結果、真空断熱材６の熱伝導率は、２．０ｍＷ／ｍ・Ｋとなった。 As a result, the thermal conductivity of the vacuum heat insulating material 6 was 2.0 mW/m·K.

上記荷重を加える前後で、熱伝導率が１．５ｍＷ／ｍ・Ｋ下がったが、このことは、真空断熱材６の気体難透過性素材からなる外被材８の内部の圧力が下がった事を意味し、さらには、気体難透過性素材からなる外被材８の外側から開封部材４に上記荷重を加えた事により、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９が作られ、気体吸着剤３が真空断熱材６の気体難透過性素材からなる外被材８の内部の気体を吸収した事を意味する。
（第２実施の形態）
図３は、本発明の第２実施の形態において、気体吸着デバイス１に搭載した開封部材４の概略図である。 Before and after applying the above load, the thermal conductivity decreased by 1.5 mW/m·K. Furthermore, by applying the above load to the opening member 4 from the outside of the outer covering material 8 made of a gas-impermeable material, the container of the gas adsorption device 1 made of a soft packaging material of a gas-impermeable material 2 is formed with an opening 9, and the gas adsorbent 3 absorbs the gas inside the outer covering material 8 made of the gas impermeable material of the vacuum heat insulating material 6.
(Second embodiment)
FIG. 3 is a schematic diagram of the unsealing member 4 mounted on the gas adsorption device 1 in the second embodiment of the present invention.

開封部材４は、突起部５が開封部材４の外表面より内側に配置されており、荷重が加えられた際に破断もしくは変形する易破断変形部１１を有しており、突起部５の位置は、易破断変形部１１で破断もしくは変形した際に、突起部５が開封部材４の外表面より外側に突出する位置であることを特徴とする。 The unsealing member 4 has a protrusion 5 arranged inside the outer surface of the unsealing member 4 and has an easily breakable deformable portion 11 that breaks or deforms when a load is applied. is a position where the projecting portion 5 protrudes outward from the outer surface of the unsealing member 4 when it is broken or deformed at the easily breakable deformable portion 11 .

突起部５および易破断変形部１１は、開封部材４に切抜部１２を配置する事で形成される。切抜部１２は、開封部材４を厚さ方向に貫通させたものである。 The projecting portion 5 and the easily breaking deformable portion 11 are formed by arranging the cut-out portion 12 in the unsealing member 4 . The cut-out portion 12 is formed by penetrating the unsealing member 4 in the thickness direction.

切抜部１２により、突起部５を鋭利な形状としており、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２と接触したときに、突起部５は気体難透過性素材の軟包材からなる容器２に集中的に荷重が加わるため、気体難透過性素材の軟包材からなる容器２に開口９が作られる。 The protrusion 5 has a sharp shape due to the cut-out portion 12 , and when it comes into contact with the container 2 made of the soft packaging material of the gas-impermeable material of the gas adsorption device 1 , the protrusion 5 is a soft material of the gas-impermeable material. Since the load is applied intensively to the container 2 made of the packaging material, an opening 9 is formed in the container 2 made of the soft packaging material of gas-impermeable material.

易破断変形部１１は、切抜部１２により開封部材４を構成する部材が、開封部材４の他の位置に比べて少ないため、荷重により破断もしくは変形し易くなっている。 The breakable deformable portion 11 is easily broken or deformed by a load because the number of members constituting the unsealing member 4 by the cutout portion 12 is smaller than other positions of the unsealing member 4 .

本実施の形態では切抜部１２により突起部５および易破断変形部１１を形成したが、その他、切り欠きや、破断や変形しやすい部材で形成しても良い。 In the present embodiment, the cutout portion 12 is used to form the projecting portion 5 and the easily breakable deformable portion 11, but they may be formed by notches or members that are easily broken or deformed.

上記図３に記載の開封部材４を、第１実施の形態同様に、気体難透過性素材の軟包材からなる気体難透過性素材の軟包材からなる容器２の内側に配置し、気体吸着デバイス１とした。 The unsealing member 4 shown in FIG. 3 is arranged inside the container 2 made of the soft packaging material of the gas-impermeable material, similarly to the first embodiment, and the gas is It is referred to as adsorption device 1 .

本実施の形態の構成により、開封部材４に荷重が加えられた際に、開封部材４の易破断変形部１１が破断もしくは変形すると共に、開封部材４の周辺の気体難透過性素材の軟包材からなる容器２が変形することとで、開封部材４が有する突起部５が気体難透過性素材の軟包材からなる容器２と接触し、突起部５が気体難透過性素材の軟包材からなる容器２に開口９を作る。 According to the configuration of this embodiment, when a load is applied to the unsealing member 4, the easily rupture deformable portion 11 of the unsealing member 4 is ruptured or deformed, and the gas-impermeable material around the unsealing member 4 is softly wrapped. When the container 2 made of the material is deformed, the projecting portion 5 of the opening member 4 comes into contact with the container 2 made of the flexible packaging material of the gas-impermeable material, and the projecting portion 5 becomes the soft packaging material of the gas-impermeable material. An opening 9 is made in a container 2 made of material.

上記構成により、第１実施の形態に記載のメリットがあるだけでなく、突起部５が開封部材４の外表面より内側に配置されているため、開口９を作る前に開封部材４が気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２を破損させるリスクをさらに低減する事ができる。 With the above configuration, there is not only the advantage described in the first embodiment, but also because the protrusions 5 are arranged inside the outer surface of the unsealing member 4, the unsealing member 4 adsorbs gas before the opening 9 is formed. It is possible to further reduce the risk of damaging the container 2 of the device 1, which is made of a soft packaging material that is impermeable to gas.

図３では、開封部材４の形状は、長方形の板状であるが、四方の角をＲ形状としたり、正方形や円形、楕円形としたりしてもよく、形状はこの限りではない。
（実施例２）
次に、第２実施の形態における気体吸着デバイス１および気体吸着デバイス１を搭載した真空断熱材６の実施例２について説明する。 In FIG. 3, the shape of the unsealing member 4 is a rectangular plate, but the shape may be rounded, square, circular, or elliptical, and the shape is not limited to this.
(Example 2)
Next, Example 2 of the gas adsorption device 1 according to the second embodiment and the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted will be described.

まず、使用した気体吸着デバイス１について説明する。 First, the used gas adsorption device 1 will be described.

開封部材４を除く気体吸着デバイス１の構成は、実施例１に記載の通りである。 The structure of the gas adsorption device 1 except for the opening member 4 is as described in the first embodiment.

開封部材４の材質は、ステンレス製の鋼板とした。 The material of the unsealing member 4 was a stainless steel plate.

開封部材４の寸法は、幅を１０ｍｍ、長さを３５ｍｍ、厚さを１ｍｍとした。 The dimensions of the opening member 4 were 10 mm in width, 35 mm in length, and 1 mm in thickness.

切抜部１２は、幅０．５ｍｍの幅で開封部材４を構成するステンレス製の鋼板を厚さ方向に貫通させて形成した。 The cut-out portion 12 was formed by penetrating the stainless steel plate forming the unsealing member 4 with a width of 0.5 mm in the thickness direction.

突起部５の先端のＲを０．５ｍｍで形成した。 R of the tip of the protrusion 5 was formed to be 0.5 mm.

易破断変形部１１は、切抜部１２により、開封部材４を構成するステンレス製の鋼板を、切抜部１２の両端の開封部材４の残肉部の幅を各１ｍｍとする事で形成した。 The easy breaking deformable portion 11 is formed by setting the width of the unsealing member 4 at both ends of the cut-out portion 12 to 1 mm on each of the stainless steel plates constituting the opening member 4 .

開封部材４の幅は３５ｍｍだが、２箇所の易破断変形部１１の幅が１ｍｍと狭くすることで、開封部材４に荷重が加わった際に、易破断変形部１１が優先的に破断もしくは変形する。 The width of the unsealing member 4 is 35 mm, but by narrowing the width of the easily rupture deformable portions 11 at two locations to 1 mm, the easily rupture deformable portions 11 are preferentially broken or deformed when a load is applied to the unsealing member 4. do.

上記開封部材４を、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２の内部に配置した。 The unsealing member 4 was placed inside the container 2 of the gas adsorption device 1, which is made of a soft packaging material that is impermeable to gas.

気体吸着デバイス１の製作方法は、実施例１に記載の通りである。 A method for manufacturing the gas adsorption device 1 is as described in the first embodiment.

開封部材４の一部に集中的に荷重を加えることで、開封部材４が有する易破断変形部１１が破断もしくは変形し、突起部５が気体難透過性素材の軟包材からなる容器２側に移動すると共に、開封部材４よりもヤング率の低い気体難透過性素材の軟包材からなる容器２が開封部材４よりも大きく変形し、開封部材４の突起部５が、気体難透過性素材の軟包材からなる容器２に接触し、開口９が作られる。 By applying a concentrated load to a part of the unsealing member 4, the breakable deformable portion 11 of the unsealing member 4 is broken or deformed, and the projecting portion 5 of the container 2 is made of a soft packaging material of gas-impermeable material. At the same time, the container 2 made of a soft packaging material having a gas-impermeable material having a Young's modulus lower than that of the unsealing member 4 deforms more than the unsealing member 4, and the protrusion 5 of the unsealing member 4 becomes gas-impermeable. An opening 9 is made in contact with a container 2 made of flexible packaging material.

このことにより、気体吸着デバイス１の内外の雰囲気が連通し、気体吸着デバイス１の周辺の気体を吸着できるようになる。 As a result, the atmosphere inside and outside the gas adsorption device 1 communicates, and the gas around the gas adsorption device 1 can be adsorbed.

次に、上記気体吸着デバイス１を、真空断熱材６に搭載した。 Next, the gas adsorption device 1 was mounted on the vacuum heat insulating material 6 .

真空断熱材６の構成および製作方法は、実施例１に記載の通りである。 The structure and manufacturing method of the vacuum heat insulating material 6 are as described in the first embodiment.

気体難透過性素材からなる外被材８の内部を減圧した真空断熱材６の熱伝導率を３．８ｍＷ／ｍ・Ｋにした。 The thermal conductivity of the vacuum heat insulating material 6, which is obtained by decompressing the inside of the outer covering material 8 made of a gas-impermeable material, is set to 3.8 mW/m·K.

その後、上記気体吸着デバイス１を搭載した真空断熱材６について、真空断熱材６の気体難透過性素材からなる外被材８の外側から、気体吸着デバイス１の開封部材４の一部に集中的に荷重を加えた。 After that, the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted is concentrated on a part of the opening member 4 of the gas adsorption device 1 from the outside of the outer covering material 8 made of a gas impermeable material of the vacuum heat insulating material 6. was loaded.

荷重を加えるために使用した設備および加えた荷重に関する条件は、実施例１に記載の通りである。 The equipment used to apply the load and the conditions for the applied load are as described in Example 1.

その結果、真空断熱材６の熱伝導率は、２．５ｍＷ／ｍ・Ｋとなった。 As a result, the thermal conductivity of the vacuum heat insulating material 6 was 2.5 mW/m·K.

荷重を加える前後で、熱伝導率が１．３ｍＷ／ｍ・Ｋ下がったが、このことは、真空断熱材６の気体難透過性素材からなる外被材８の内部の圧力が下がった事を意味する。 Before and after the load was applied, the thermal conductivity decreased by 1.3 mW/m·K. means.

このことから、気体難透過性素材からなる外被材８の外側から開封部材４に荷重を加えた事により、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９が作られ、気体吸着剤３が真空断熱材６の気体難透過性素材からなる外被材８の内部の気体を吸収したと言える。 Therefore, by applying a load to the unsealing member 4 from the outside of the jacket material 8 made of a gas-impermeable material, an opening 9 is formed in the container 2 of the gas adsorption device 1 made of a soft packaging material of a gas-impermeable material. is produced, and the gas adsorbent 3 can be said to have absorbed the gas inside the outer covering material 8 made of the gas-impermeable material of the vacuum heat insulating material 6 .

上記確認の後、真空断熱材６から気体吸着デバイス１を取り出し確認したところ、開封部材４は易破断変形部１１で変形しており、突起部５が気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２を突き破り、開口９を形成している事を確認した。 After the above confirmation, the gas adsorption device 1 was taken out from the vacuum insulation material 6 and confirmed. It was confirmed that the container 2 made of soft packaging material was pierced and the opening 9 was formed.

本実施例において、切抜部１２により突起部５を形成したが、開封部材４を貫通させるかわりに、切り欠きや、軟質材とするなどとしても同様の効果を実現できる。
（実施例３）
次に、第２実施の形態における気体吸着デバイス１および気体吸着デバイス１を搭載した真空断熱材６の実施例３について説明する。 In this embodiment, the protrusion 5 is formed by the cut-out portion 12, but the same effect can be achieved by notching or using a soft material instead of allowing the unsealing member 4 to pass through.
(Example 3)
Next, Example 3 of the gas adsorption device 1 according to the second embodiment and the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted will be described.

まず、使用した気体吸着デバイス１について説明する。 First, the used gas adsorption device 1 will be described.

開封部材４の材質を除く気体吸着デバイス１の構成は、実施例２に記載の通りである。 The structure of the gas adsorption device 1 except for the material of the opening member 4 is as described in the second embodiment.

開封部材４の材質は、ＳＫ鋼板とした。 The material of the unsealing member 4 was SK steel plate.

ＳＫ鋼板は、ステンレス鋼板よりも硬く脆いため、ステンレス鋼板よりも変形しづらく、破断しやすい性質を持つ。 Since the SK steel plate is harder and more brittle than the stainless steel plate, it is less deformable than the stainless steel plate and easily broken.

この材質にする事により、易破断変形部１１は、変形ではなく破断し易い状態になる。 By using this material, the easily fracture deformable portion 11 is in a state of being easily fractured rather than being deformed.

破断により、音波などの振動が発生する。 The rupture generates vibrations such as sound waves.

そのため、開封部材４に荷重が加えられ、易破断変形部１１が破断する際に、発生する音波により、易破断変形部の破断と、それに伴う気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２への開口９の形成を確認可能にする事ができる。 Therefore, when a load is applied to the unsealing member 4 and the easily rupturable deformable portion 11 is ruptured, the generated sound waves cause the easily rupturable deformable portion to break and the gas impermeable material of the gas adsorption device 1 to break. It is possible to make it possible to confirm the formation of the opening 9 in the container 2 made of material.

次に、上記気体吸着デバイス１を、真空断熱材６に搭載した。 Next, the gas adsorption device 1 was mounted on the vacuum heat insulating material 6 .

真空断熱材６の構成および製作方法は、実施例１に記載の通りである。 The structure and manufacturing method of the vacuum heat insulating material 6 are as described in the first embodiment.

気体難透過性素材からなる外被材８の内部を減圧した真空断熱材６の熱伝導率を３．６ｍＷ／ｍ・Ｋにした。 The heat conductivity of the vacuum heat insulating material 6 whose inside of the outer covering material 8 made of a gas-impermeable material is decompressed is set to 3.6 mW/m·K.

その後、上記気体吸着デバイス１を搭載した真空断熱材６について、真空断熱材６の気体難透過性素材からなる外被材８の外側から、気体吸着デバイス１の開封部材４の一部に集中的に荷重を加えた。 After that, the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted is concentrated on a part of the opening member 4 of the gas adsorption device 1 from the outside of the outer covering material 8 made of a gas impermeable material of the vacuum heat insulating material 6. was loaded.

荷重を加えるために使用した設備および加えた荷重に関する条件は、実施例１に記載の通りである。 The equipment used to apply the load and the conditions for the applied load are as described in Example 1.

その結果、荷重を加えた際に、聴覚で明確に確認できる音が発生した。 As a result, when the load was applied, a sound that was clearly audible was generated.

また、真空断熱材６の熱伝導率は、２．３ｍＷ／ｍ・Ｋとなった。 Moreover, the thermal conductivity of the vacuum heat insulating material 6 was 2.3 mW/m·K.

さらに真空断熱材６から気体吸着デバイス１を取り出し確認したところ、開封部材４は易破断変形部１１で破断しており、突起部５が気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２を突き破り、開口９を形成している事を確認した。 Furthermore, when the gas adsorption device 1 was taken out from the vacuum heat insulating material 6 and confirmed, the opening member 4 was broken at the easily breakable deformable portion 11, and the projecting portion 5 was removed from the gas impermeable soft packaging material of the gas adsorption device 1. It was confirmed that the opening 9 was formed by breaking through the container 2.

このことから、開封部材４は易破断変形部１１で破断し、その際に聴覚で明確に確認できる音を発生し、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９を形成し、気体吸着剤３が真空断熱材６の気体難透過性素材からなる外被材８の内部の気体を吸収した事を確認した。 As a result, the opening member 4 is broken at the easily broken deformable portion 11, and at that time, a sound that can be clearly confirmed by hearing is generated. An opening 9 was formed, and it was confirmed that the gas adsorbent 3 absorbed the gas inside the jacket material 8 made of the gas impermeable material of the vacuum heat insulating material 6 .

上記のことから、易破断変形部１１に脆性材料を用いることで、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９が作られた事を音波によって確認できる。 As described above, by using a brittle material for the easily fracture deformable portion 11, it can be confirmed by sound waves that the opening 9 is formed in the container 2 of the gas adsorption device 1 made of the soft packaging material of the gas impermeable material.

次に、第２実施の形態における気体吸着デバイス１および気体吸着デバイス１を搭載した真空断熱材６の実施例４について説明する。 In the present embodiment, the protrusion 5 and the breakable deformable portion 11 are formed by the cut-out portion 12, but similar effects can be achieved by notching or using a soft material instead of penetrating. (Example 4)
Next, Example 4 of the gas adsorption device 1 according to the second embodiment and the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted will be described.

まず、使用した気体吸着デバイス１について説明する。 First, the used gas adsorption device 1 will be described.

開封部材４を除く気体吸着デバイス１の構成は、実施例１に記載の通りである。 The structure of the gas adsorption device 1 except for the opening member 4 is as described in the first embodiment.

使用した開封部材４の構成を図４に示す。 The configuration of the used opening member 4 is shown in FIG.

開封部材４の材質は、ステンレス製の鋼板とした。 The material of the unsealing member 4 was a stainless steel plate.

寸法は、３０ｍｍ角、厚さを１ｍｍとした。 The dimensions were 30 mm square and 1 mm thick.

開封部材４は、切抜部１２を十字に形成する事により、突起部５を４箇所有するものとした。 The opening member 4 has four projecting portions 5 by forming the cutout portion 12 in a cross shape.

切抜部１２は、開封部材４を厚さ方向に０．５ｍｍの幅で貫通させて形成した。 The cut-out portion 12 was formed by penetrating the unsealing member 4 with a width of 0.5 mm in the thickness direction.

突起部５の先端のＲは０．５ｍｍで形成した。 R of the tip of the protrusion 5 was formed to be 0.5 mm.

易破断変形部１１は、切抜部１２により、開封部材４を構成するステンレス製の鋼板を、切抜部１２の両端の開封部材４の残肉部の幅を各１ｍｍとする事で形成した。 The easy breaking deformable portion 11 is formed by setting the width of the unsealing member 4 at both ends of the cut-out portion 12 to 1 mm on each of the stainless steel plates constituting the opening member 4 .

開封部材４の幅方向の寸法は３０ｍｍだが、４箇所の易破断変形部１１の幅を各１ｍｍと狭くすることで、開封部材４に荷重が加わった際に、易破断変形部１１が優先的に破断もしくは変形する。 Although the size of the opening member 4 in the width direction is 30 mm, by narrowing the width of each of the four easy-to-break deformation portions 11 to 1 mm, when a load is applied to the opening member 4, the easy-to-break deformation portion 11 is given priority. break or deform.

上記開封部材４を、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２の内部に配置した。 The unsealing member 4 was placed inside the container 2 of the gas adsorption device 1, which is made of a soft packaging material that is impermeable to gas.

気体吸着デバイス１の製作方法は、実施例１に記載の通りである。 A method for manufacturing the gas adsorption device 1 is as described in the first embodiment.

開封部材４の一部に集中的に荷重を加えることで、開封部材４が有する易破断変形部１１が破断もしくは変形し、突起部５が気体難透過性素材の軟包材からなる容器２側に移動する事で、開封部材４の突起部５が、気体難透過性素材の軟包材からなる容器２に接触し、開口９が作られる。 By applying a concentrated load to a part of the unsealing member 4, the breakable deformable portion 11 of the unsealing member 4 is broken or deformed, and the projecting portion 5 of the container 2 is made of a soft packaging material of gas-impermeable material. , the protrusion 5 of the opening member 4 comes into contact with the container 2 made of a soft packaging material that is impermeable to gas, and an opening 9 is formed.

このことにより、気体吸着デバイス１の内外の雰囲気が連通し、気体吸着デバイス１の周辺の気体を吸着できるようになる。 As a result, the atmosphere inside and outside the gas adsorption device 1 communicates, and the gas around the gas adsorption device 1 can be adsorbed.

上記開封部材４のように、突起部５を複数設け、なおかつ易破断変形部１１を開封部材４の端部に配置する事により、開封部材４に荷重を加える位置が、開封部材４から外れない範囲においてずれたとしても、易破断変形部１１が破断もしくは変形し、突起部５が気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に接触し、開口９が形成される。 By providing a plurality of protrusions 5 and arranging the easily breaking deformable portion 11 at the end of the opening member 4 as in the opening member 4, the position where the load is applied to the opening member 4 does not deviate from the opening member 4. Even if it deviates within the range, the easily rupturable deformable portion 11 is broken or deformed, the projecting portion 5 comes into contact with the container 2 of the gas adsorption device 1 made of a soft packaging material of a gas impermeable material, and an opening 9 is formed. .

次に、上記気体吸着デバイス１を搭載した、真空断熱材６について説明する。 Next, the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted will be described.

真空断熱材６の構成および製作方法は、実施例１に記載の通りである。 The structure and manufacturing method of the vacuum heat insulating material 6 are as described in the first embodiment.

気体難透過性素材からなる外被材８の内部を減圧した真空断熱材６の熱伝導率は、３．３ｍＷ／ｍ・Ｋにした。 The thermal conductivity of the vacuum heat insulating material 6 in which the inside of the outer covering material 8 made of a gas-impermeable material is depressurized was set to 3.3 mW/m·K.

その後、上記気体吸着デバイス１を搭載した真空断熱材６について、真空断熱材６の気体難透過性素材からなる外被材８の外側から、気体吸着デバイス１の開封部材４の一部に集中的に荷重を加えた。 After that, the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted is concentrated on a part of the opening member 4 of the gas adsorption device 1 from the outside of the outer covering material 8 made of a gas impermeable material of the vacuum heat insulating material 6. was loaded.

荷重を加えるために使用した設備は、プレス機にφ５ｍｍのウレタン製の治具を固定して使用した。 The equipment used to apply the load was a pressing machine with a φ5 mm urethane jig fixed.

上記プレス機により、開封部材４に、気体難透過性素材からなる外被材８の外側から２０ｋｇｆの力を加えた。 A force of 20 kgf was applied to the unsealing member 4 from the outside of the covering member 8 made of a gas impermeable material by the press machine.

その結果、真空断熱材６の熱伝導率は、２．５ｍＷ／ｍ・Ｋとなった。 As a result, the thermal conductivity of the vacuum heat insulating material 6 was 2.5 mW/m·K.

上記荷重により、熱伝導率が０．８ｍＷ／ｍ・Ｋ下がったが、このことは、真空断熱材６の気体難透過性素材からなる外被材８の内部の圧力が下がった事を意味し、さらには気体難透過性素材からなる外被材８の外側から開封部材４に上記荷重が加えられた事により、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９が作られ、気体吸着剤３が真空断熱材６の気体難透過性素材からなる外被材８の内部の気体を吸収した事を意味する。 Due to the above load, the thermal conductivity decreased by 0.8 mW/m·K, which means that the pressure inside the outer covering material 8 made of the gas-impermeable material of the vacuum heat insulating material 6 decreased. Further, the load is applied to the unsealing member 4 from the outside of the jacket material 8 made of a gas-impermeable material, so that the container 2 of the gas adsorption device 1 made of a soft packaging material of a gas-impermeable material is opened. 9 is produced, and the gas adsorbent 3 has absorbed the gas inside the outer covering material 8 made of the gas impermeable material of the vacuum heat insulating material 6 .

実施例１と比較して、本実施例は開封部材４に荷重を加えるために使用した治具の先端径を小さくしたが、本実施例の開封部材の構成のように、突起部５を複数設け、気体難透過性素材の軟包材からなる容器２の表面に対して水平な面上で、様々な角度に配置する事で、安定して開封する事が可能になる。 Compared with Example 1, the tip diameter of the jig used for applying a load to the unsealing member 4 in this example was made smaller. By arranging them at various angles on a plane horizontal to the surface of the container 2 made of a soft packaging material of gas-impermeable material, it is possible to stably unseal the container.

また本実施例において、切抜部１２により突起部５および易破断変形部１１を形成したが、切り欠きや、軟質材とするなどとしても同様の効果を実現できる。
（実施例５）
次に、第２実施の形態における気体吸着デバイス１および気体吸着デバイス１を搭載した真空断熱材６の実施例５について説明する。 Further, in the present embodiment, the protrusion 5 and the easily fracture deformable portion 11 are formed by the cutout portion 12, but the same effect can be achieved by notching or using a soft material.
(Example 5)
Next, Example 5 of the gas adsorption device 1 according to the second embodiment and the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted will be described.

まず、使用した気体吸着デバイス１について説明する。 First, the used gas adsorption device 1 will be described.

開封部材４を除く気体吸着デバイス１の構成は、実施例１に記載の通りである。 The structure of the gas adsorption device 1 except for the opening member 4 is as described in the first embodiment.

使用した開封部材４の概略図を図５に示す。 A schematic diagram of the used opening member 4 is shown in FIG.

開封部材４の材質は、ステンレス製の鋼板とした。 The material of the unsealing member 4 was a stainless steel plate.

開封部材４の寸法は、幅を１０ｍｍ、長さを３５ｍｍ、厚さを１ｍｍとした。 The dimensions of the opening member 4 were 10 mm in width, 35 mm in length, and 1 mm in thickness.

切抜部１２は、幅０．５ｍｍの幅で開封部材４を構成するステンレス製の鋼板を厚さ方向に貫通させて、合計で３箇所形成した。 A total of three cutouts 12 were formed by penetrating the stainless steel plate forming the opening member 4 with a width of 0.5 mm in the thickness direction.

切抜部１２の一つは、開封部材４の略中央部に設け、易破断変形部１１と突起部５を形成した。 One of the cut-out portions 12 was provided substantially in the central portion of the unsealing member 4 to form the easily breakable deformable portion 11 and the projecting portion 5 .

突起部５の先端のＲを０．５ｍｍとした。 R of the tip of the protrusion 5 was set to 0.5 mm.

切抜部１２の残りの二つは、開封部材の端部に設け、易破断変形部１１を形成した。 The remaining two cut-out portions 12 were provided at the ends of the opening member to form easily fracture deformable portions 11 .

易破断変形部１１は全て、切抜部１２により、開封部材４を構成するステンレス製の鋼板を、切抜部１２の両端の開封部材４の残肉部の幅を各１ｍｍとする事で形成した。 All of the easy-to-break deformable portions 11 are formed by cutting out portions 12 from a stainless steel plate forming the opening member 4 and setting the width of the remaining portions of the opening member 4 at both ends of the cutout portion 12 to 1 mm.

本実施例の開封部材４の幅は３５ｍｍだが、２箇所の易破断変形部１１の幅が１ｍｍと狭くすることで、開封部材４に荷重が加わった際に、易破断変形部１１が優先的に破断もしくは変形する。 Although the width of the opening member 4 in this embodiment is 35 mm, the width of the easily breaking deformable portions 11 at the two locations is narrowed to 1 mm, so that when a load is applied to the opening member 4, the easily breaking deformable portions 11 are given priority. break or deform.

上記のように、気体吸着デバイス１が有する開封部材４に対して、切抜部１２および易破断変形部１１を開封部材４の端部に設ける事で、開封部材４の一部に集中的に荷重を加え、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９を作る際に、開封部材４の端部に設けられた易破断変形部１１が破断もしくは変形し、開封部材４の端部が開口９と逆の方向に移動する量を低減し、開封部材４が気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２および気体吸着デバイス１を搭載した真空断熱材６の気体難透過性素材からなる外被材８を破損するリスクを低減できる。 As described above, with respect to the opening member 4 of the gas adsorption device 1, by providing the cutout portion 12 and the easy breaking deformation portion 11 at the end portion of the opening member 4, the load is concentrated on a part of the opening member 4. is added, and when the opening 9 is formed in the container 2 of the gas adsorption device 1 made of a soft packaging material made of a gas-impermeable material, the easily breakable deformable portion 11 provided at the end of the unsealing member 4 is broken or deformed, The container 2 and the gas adsorption device 1 are mounted. It is possible to reduce the risk of damaging the outer covering material 8 made of the gas-impermeable material of the vacuum heat insulating material 6 .

上記開封部材４を、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２の内部に配置した。 The unsealing member 4 was placed inside the container 2 of the gas adsorption device 1, which is made of a soft packaging material that is impermeable to gas.

気体吸着デバイス１の製作方法は、実施例１に記載の通りである。 A method for manufacturing the gas adsorption device 1 is as described in the first embodiment.

次に、上記気体吸着デバイス１を、真空断熱材６に搭載した。 Next, the gas adsorption device 1 was mounted on the vacuum heat insulating material 6 .

真空断熱材６の構成および製作方法は、実施例１に記載の通りである。 The structure and manufacturing method of the vacuum heat insulating material 6 are as described in the first embodiment.

気体難透過性素材からなる外被材８の内部を減圧した真空断熱材６の熱伝導率を３．５ｍＷ／ｍ・Ｋにした。 The thermal conductivity of the vacuum heat insulating material 6 whose inside of the outer covering material 8 made of a gas impermeable material is decompressed is set to 3.5 mW/m·K.

その後、上記気体吸着デバイス１を搭載した真空断熱材６について、真空断熱材６の気体難透過性素材からなる外被材８の外側から、気体吸着デバイス１の開封部材４の一部に集中的に荷重を加えた。 After that, the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted is concentrated on a part of the opening member 4 of the gas adsorption device 1 from the outside of the outer covering material 8 made of a gas impermeable material of the vacuum heat insulating material 6. was loaded.

荷重を加えるために使用した設備および加えた荷重に関する条件は、実施例１に記載の通りである。 The equipment used to apply the load and the conditions for the applied load are as described in Example 1.

その結果、真空断熱材６の熱伝導率は、２．４ｍＷ／ｍ・Ｋとなった。 As a result, the thermal conductivity of the vacuum heat insulating material 6 was 2.4 mW/m·K.

荷重を加える前後で、熱伝導率が１．１ｍＷ／ｍ・Ｋ下がったが、このことは、真空断熱材６の気体難透過性素材からなる外被材８の内部の圧力が下がった事を意味し、さらには、気体難透過性素材からなる外被材８の外側から開封部材４に荷重を加えた事により、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９が作られ、気体吸着剤３が真空断熱材６の気体難透過性素材からなる外被材８の内部の気体を吸収した事を意味する。 Before and after the load was applied, the thermal conductivity decreased by 1.1 mW/m·K. Furthermore, by applying a load to the unsealing member 4 from the outside of the jacket material 8 made of the gas-impermeable material, the container 2 of the gas adsorption device 1 made of the soft packaging material of the gas-impermeable material is It means that the opening 9 is made and the gas adsorbent 3 has absorbed the gas inside the outer covering material 8 made of the gas impermeable material of the vacuum heat insulating material 6 .

上記確認の後、真空断熱材６の上記荷重を加えた側の気体難透過性素材からなる外被材８について、気体吸着デバイス１の開封部材４の端部の位置で、気体難透過性素材からなる外被材８に発生する段差を測定したところ、０．１ｍｍ以下であった。比較として実施例２に記載の方法で気体吸着デバイス１に開口９を作るための荷重を加えた後の真空断熱材６について同様に測定したところ、この段差は０．５ｍｍであった。 After the above confirmation, the outer covering material 8 made of the gas impermeable material on the side of the vacuum heat insulating material 6 to which the load was applied was attached to the gas impermeable material at the end of the opening member 4 of the gas adsorption device 1. When the step generated in the outer covering material 8 made of was measured, it was 0.1 mm or less. As a comparison, when the load for forming the openings 9 was applied to the gas adsorption device 1 by the method described in Example 2, and the vacuum heat insulating material 6 was similarly measured, the step was 0.5 mm.

段差が少ない事は、開封部材４が気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２もしくは真空断熱材６の気体難透過性素材からなる外被材８にストレスを加えて、気体難透過性素材の軟包材からなる容器２もしくは気体難透過性素材からなる外被材８が破壊される事を防ぐばかりでなく、真空断熱材６が、擦れや圧縮など外から加えられるストレスによって気体難透過性素材からなる外被材８が破壊される事も防ぐ事を意味する。 The fact that the difference in level is small means that the unsealing member 4 applies stress to the container 2 made of the soft packaging material of the gas-impermeable material of the gas adsorption device 1 or the outer covering material 8 of the vacuum insulation material 6 made of the material of the gas-impermeable material. In addition to preventing breakage of the container 2 made of a soft packaging material of a gas-impermeable material or the outer covering material 8 of a gas-impermeable material, the vacuum heat insulating material 6 is protected from external forces such as rubbing and compression. It also means that the outer covering material 8 made of a gas impermeable material is prevented from being destroyed by the applied stress.

この事から、開封部材４の端部に易破断変形部１１を設ける事で、気体吸着デバイス１および真空断熱材６の破損を防ぐ事ができる。 For this reason, by providing the breakable deformable portion 11 at the end of the unsealing member 4, the gas adsorption device 1 and the vacuum heat insulating material 6 can be prevented from being damaged.

本実施例において、切抜部１２により突起部５および易破断変形部１１を形成したが、切り欠きや、軟質材とするなどとしても同様の効果を実現できる。
（実施例６）
次に、第２実施の形態における気体吸着デバイス１および気体吸着デバイス１を搭載した真空断熱材６の実施例６について説明する。 In this embodiment, the protrusion 5 and the easily fracture deformable portion 11 are formed by the cut-out portion 12, but the same effect can be achieved by notching or using a soft material.
(Example 6)
Next, Example 6 of the gas adsorption device 1 according to the second embodiment and the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted will be described.

まず、使用した気体吸着デバイス１について説明する。 First, the used gas adsorption device 1 will be described.

開封部材４を除く気体吸着デバイス１の構成は、実施例１に記載の通りである。 The structure of the gas adsorption device 1 except for the opening member 4 is as described in the first embodiment.

使用した開封部材４の概略図を図６に示す。 A schematic diagram of the opening member 4 used is shown in FIG.

開封部材４の材質は、ステンレス製の鋼板とした。 The material of the unsealing member 4 was a stainless steel plate.

開封部材４の寸法は、幅を１０ｍｍ、長さを３５ｍｍ、厚さを１ｍｍとした。 The dimensions of the opening member 4 were 10 mm in width, 35 mm in length, and 1 mm in thickness.

切抜部１２は、幅０．５ｍｍの幅で開封部材４を構成するステンレス製の鋼板を厚さ方向に貫通させて形成した。 The cut-out portion 12 was formed by penetrating the stainless steel plate forming the unsealing member 4 with a width of 0.5 mm in the thickness direction.

突起部５の先端のＲを０．５ｍｍで形成した。 R of the tip of the protrusion 5 was formed to be 0.5 mm.

易破断変形部１１は、切抜部１２により、開封部材４を構成するステンレス製の鋼板を、各１ｍｍの幅のみ存在させる事で形成した。 The easy-to-break deformable portion 11 was formed by making the stainless steel plate constituting the opening member 4 exist only with a width of 1 mm by the cut-out portion 12 .

開封部材４の幅は３５ｍｍだが、２箇所の易破断変形部１１のみ幅を１ｍｍとすることで、開封部材４に荷重が加わった際に、易破断変形部１１が優先的に破断もしくは変形するようにした。 The width of the unsealing member 4 is 35 mm, but by setting the width of only the easily rupture deformable portions 11 at two locations to 1 mm, the easily rupture deformable portions 11 are preferentially broken or deformed when a load is applied to the unsealing member 4. I made it

板状の開封部材４を長辺側からみた断面形状は、湾曲した形状とした。 The cross-sectional shape of the plate-like unsealing member 4 viewed from the long side is curved.

上記開封部材４を、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２の内部に配置した。 The unsealing member 4 was placed inside the container 2 of the gas adsorption device 1, which is made of a soft packaging material that is impermeable to gas.

気体吸着デバイス１の製作方法は、実施例１に記載の通りである。 A method for manufacturing the gas adsorption device 1 is as described in the first embodiment.

次に、上記気体吸着デバイス１を、真空断熱材６に搭載した。 Next, the gas adsorption device 1 was mounted on the vacuum heat insulating material 6 .

真空断熱材６の構成および製作方法は、実施例１に記載の通りである。 The structure and manufacturing method of the vacuum heat insulating material 6 are as described in the first embodiment.

気体難透過性素材からなる外被材８の内部を減圧した真空断熱材６の熱伝導率を３．８ｍＷ／ｍ・Ｋにした。 The thermal conductivity of the vacuum heat insulating material 6, which is obtained by decompressing the inside of the outer covering material 8 made of a gas-impermeable material, is set to 3.8 mW/m·K.

その後、上記気体吸着デバイス１を搭載した真空断熱材６について、真空断熱材６の気体難透過性素材からなる外被材８の外側から、気体吸着デバイス１の開封部材４の一部に集中的に荷重を加えた。 After that, the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted is concentrated on a part of the opening member 4 of the gas adsorption device 1 from the outside of the outer covering material 8 made of a gas impermeable material of the vacuum heat insulating material 6. was loaded.

荷重を加えるために使用した設備および加えた荷重に関する条件は、実施例１に記載の通りであるが、荷重を加える方向は、湾曲した開封部材４の、凸側から荷重を加えた。 The equipment used for applying the load and the conditions regarding the applied load were as described in Example 1, but the load was applied from the convex side of the curved opening member 4 .

その結果、真空断熱材６の熱伝導率は、２．６ｍＷ／ｍ・Ｋとなった。 As a result, the thermal conductivity of the vacuum heat insulating material 6 was 2.6 mW/m·K.

荷重を加える前後で、熱伝導率が１．２ｍＷ／ｍ・Ｋ下がったが、このことは、真空断熱材６の気体難透過性素材からなる外被材８の内部の圧力が下がった事を意味し、さらには、気体難透過性素材からなる外被材８の外側から開封部材４に荷重を加えた事により、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９が作られ、気体吸着剤３が真空断熱材６の気体難透過性素材からなる外被材８の内部の気体を吸収したと言える。 Before and after the load was applied, the thermal conductivity decreased by 1.2 mW/m·K. Furthermore, by applying a load to the unsealing member 4 from the outside of the jacket material 8 made of the gas-impermeable material, the container 2 of the gas adsorption device 1 made of the soft packaging material of the gas-impermeable material is It can be said that the opening 9 was made and the gas adsorbent 3 absorbed the gas inside the outer covering material 8 made of the gas impermeable material of the vacuum heat insulating material 6 .

上記確認の後、真空断熱材６の上記荷重を加えた側の気体難透過性素材からなる外被材８について、気体吸着デバイス１の開封部材４の端部の位置で、気体難透過性素材からなる外被材８に発生する段差を測定したところ、０．１ｍｍ以下であった。比較として実施例２に記載の方法で荷重を加えた後の真空断熱材６について同様に測定したところ、この段差は０．５ｍｍであった。 After the above confirmation, the outer covering material 8 made of the gas impermeable material on the side of the vacuum heat insulating material 6 to which the load was applied was attached to the gas impermeable material at the end of the opening member 4 of the gas adsorption device 1. When the step generated in the outer covering material 8 made of was measured, it was 0.1 mm or less. As a comparison, when the vacuum heat insulating material 6 after applying the load by the method described in Example 2 was measured in the same manner, the step was 0.5 mm.

段差が少ない事は、開封部材４が気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２もしくは真空断熱材６の気体難透過性素材からなる外被材８にストレスを加えて、気体難透過性素材の軟包材からなる容器２もしくは気体難透過性素材からなる外被材８が破壊される事を防ぐばかりでなく、真空断熱材６が、擦れや圧縮など外から加えられるストレスによって気体難透過性素材からなる外被材８が破壊される事も防ぐ。 The fact that the difference in level is small means that the unsealing member 4 applies stress to the container 2 made of the soft packaging material of the gas-impermeable material of the gas adsorption device 1 or the outer covering material 8 of the vacuum insulation material 6 made of the material of the gas-impermeable material. In addition to preventing breakage of the container 2 made of a soft packaging material of a gas-impermeable material or the outer covering material 8 of a gas-impermeable material, the vacuum heat insulating material 6 is protected from external forces such as rubbing and compression. It also prevents the outer covering material 8 made of gas impermeable material from being destroyed by the stress applied.

本実施例において、開封部材４の断面形状は長辺側から見て湾曲した形状としたが、長辺側でなく易破断変形部１１の位置によっては短辺側であっても同様の効果を実現でき、また、湾曲した形状ではなく端部で折れ曲がった形状であっても同様の効果を実現できる。 In this embodiment, the cross-sectional shape of the unsealing member 4 is curved when viewed from the long side. Moreover, the same effect can be achieved even if the shape is bent at the end instead of the curved shape.

まず、使用した気体吸着デバイス１について説明する。 First, the used gas adsorption device 1 will be described.

開封部材４を除く気体吸着デバイス１の構成は、実施例１に記載の通りである。 The structure of the gas adsorption device 1 except for the opening member 4 is as described in the first embodiment.

開封部材４の材質および形状は実施例１に記載の通りとした。 The material and shape of the opening member 4 were as described in Example 1.

ただし開封部材４の位置は、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２の外側に、ウレタン系の接着剤で接着した。 However, the position of the unsealing member 4 was adhered to the outside of the container 2 of the gas adsorption device 1 made of a soft packaging material made of a gas-impermeable material with a urethane-based adhesive.

次に、上記気体吸着デバイス１を、真空断熱材６に搭載した。 Next, the gas adsorption device 1 was mounted on the vacuum heat insulating material 6 .

真空断熱材６の構成および製作方法は、実施例１に記載の通りである。 The structure and manufacturing method of the vacuum heat insulating material 6 are as described in the first embodiment.

気体難透過性素材からなる外被材８の内部を減圧した真空断熱材６の熱伝導率を４．０ｍＷ／ｍ・Ｋにした。 The thermal conductivity of the vacuum heat insulating material 6 whose inside of the outer covering material 8 made of a gas-impermeable material is decompressed is set to 4.0 mW/m·K.

その後、上記気体吸着デバイス１を搭載した真空断熱材６について、真空断熱材６の気体難透過性素材からなる外被材８の外側から、気体吸着デバイス１の開封部材４の一部に集中的に荷重を加えた。 After that, the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted is concentrated on a part of the opening member 4 of the gas adsorption device 1 from the outside of the outer covering material 8 made of a gas impermeable material of the vacuum heat insulating material 6. was loaded.

(Fourth embodiment)
When the gas adsorption device 1 described in the first embodiment of the present invention is used to form the vacuum heat insulating material 6, the gas adsorption device 1 is composed of the core material 7 and the outer covering material 8 made of a gas impermeable material. inserted in between.

従来、気体吸着デバイス１を含む芯材７と共に真空断熱材６に挿入されるデバイスは、気体難透過性素材からなる外被材８の保護の観点から、芯材７の内部に配置される事が主流であった。 Conventionally, the device inserted into the vacuum insulation material 6 together with the core material 7 including the gas adsorption device 1 is arranged inside the core material 7 from the viewpoint of protecting the outer covering material 8 made of a gas impermeable material. was the mainstream.

本発明の開封部材４を含む気体吸着デバイス１は薄く、なおかつ開封部材４がデバイス内部に配置されているため、気体難透過性素材からなる外被材８に接して配置しても、気体難透過性素材からなる外被材８を破損させる事はない。 Since the gas adsorption device 1 including the unsealing member 4 of the present invention is thin and the unsealing member 4 is arranged inside the device, even if it is placed in contact with the outer covering material 8 made of a gas-impermeable material, it will not be gas-resistant. The covering material 8 made of a permeable material is not damaged.

この事は、気体吸着デバイス１を容易に真空断熱材６の気体難透過性素材からなる外被材８内部に挿入できる事を意味する。 This means that the gas adsorption device 1 can be easily inserted into the outer covering material 8 of the vacuum heat insulating material 6 made of a gas impermeable material.

さらには真空断熱材６の気体難透過性素材からなる外被材８の外側から、気体吸着デバイス１を容易に視認する事が可能にせしめる。 Furthermore, the gas adsorption device 1 can be easily visually recognized from the outside of the outer covering material 8 made of the gas-impermeable material of the vacuum heat insulating material 6 .

これにより、真空断熱材６の製作および開封部材４による開口９の作成の両方を容易にする。
（実施例８）
次に、第４実施の形態における気体吸着デバイス１および気体吸着デバイス１を搭載した真空断熱材６の実施例８について説明する。 This facilitates both the fabrication of the vacuum insulation 6 and the creation of the opening 9 by the opening member 4 .
(Example 8)
Next, Example 8 of the gas adsorption device 1 according to the fourth embodiment and the vacuum heat insulating material 6 on which the gas adsorption device 1 is mounted will be described.

使用した気体吸着デバイス１は、実施例１に記載の通りである。 The gas adsorption device 1 used is as described in Example 1.

上記開封部材４を、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２の内部に配置した。 The unsealing member 4 was placed inside the container 2 of the gas adsorption device 1, which is made of a soft packaging material that is impermeable to gas.

気体吸着デバイス１の製作方法は、実施例１に記載の通りであるが、気体吸着デバイス１を芯材７と気体難透過性素材からなる外被材８の間に配置した。 The method of manufacturing the gas adsorption device 1 was as described in Example 1, but the gas adsorption device 1 was arranged between the core material 7 and the jacket material 8 made of a gas impermeable material.

気体難透過性素材からなる外被材８の内部を減圧した真空断熱材６の熱伝導率を３．５ｍＷ／ｍ・Ｋにした。 The thermal conductivity of the vacuum heat insulating material 6 whose inside of the outer covering material 8 made of a gas impermeable material is decompressed is set to 3.5 mW/m·K.

開封部材４の部分と、それ以外の部分で、真空断熱材６の気体難透過性素材からなる外被材８の表面に発生する段差を測定したところ、０．５ｍｍであった。 The difference in level between the unsealing member 4 and the other parts was measured to be 0.5 mm.

比較として実施例２に記載の方法で荷重を加えた真空断熱材６について同様に測定したところ、この段差は０．３ｍｍであった。 As a comparison, when the vacuum heat insulating material 6 to which the load was applied by the method described in Example 2 was measured in the same manner, the step was 0.3 mm.

この事から、本発明のデバイスは真空断熱材６の気体難透過性素材からなる外被材８の近傍に配置できるため、気体難透過性素材からなる外被材８の外側からの、気体吸着デバイス１の開封部材の視認性をより高める事ができる。 From this fact, since the device of the present invention can be arranged in the vicinity of the outer covering material 8 made of the gas-impermeable material of the vacuum heat insulating material 6, the gas adsorption from the outside of the outer covering material 8 made of the gas-impermeable material. The visibility of the opening member of the device 1 can be further improved.

上記確認の後、本実施例に記載の上記気体吸着デバイス１を搭載した真空断熱材６について、真空断熱材６の気体難透過性素材からなる外被材８の外側から、気体吸着デバイス１の開封部材４の一部に集中的に荷重を加えた。 After the above confirmation, the vacuum heat insulating material 6 mounted with the gas adsorption device 1 described in the present embodiment is coated with the gas adsorption device 1 from the outside of the outer covering material 8 made of a gas-impermeable material of the vacuum heat insulating material 6. A concentrated load was applied to a part of the opening member 4 .

荷重を加えるために使用した設備および加えた荷重に関する条件は、実施例１に記載の通りである。 The equipment used to apply the load and the conditions for the applied load are as described in Example 1.

その結果、真空断熱材６の熱伝導率は、２．７ｍＷ／ｍ・Ｋとなった。 As a result, the thermal conductivity of the vacuum heat insulating material 6 was 2.7 mW/m·K.

荷重を加える前後で、熱伝導率が０．８ｍＷ／ｍ・Ｋ下がったが、このことは、真空断熱材６の気体難透過性素材からなる外被材８の内部の圧力が下がった事を意味し、さらには、気体難透過性素材からなる外被材８の外側から開封部材４に荷重を加えた事により、気体吸着デバイス１の気体難透過性素材の軟包材からなる容器２に開口９が作られ、気体吸着剤３が真空断熱材６の気体難透過性素材からなる外被材８の内部の気体を吸収した事を意味する。 Before and after the load was applied, the thermal conductivity decreased by 0.8 mW/m·K. Furthermore, by applying a load to the unsealing member 4 from the outside of the jacket material 8 made of the gas-impermeable material, the container 2 of the gas adsorption device 1 made of the soft packaging material of the gas-impermeable material is It means that the opening 9 is made and the gas adsorbent 3 has absorbed the gas inside the outer covering material 8 made of the gas impermeable material of the vacuum heat insulating material 6 .

本実施例では気体吸着デバイス１を芯材７と気体難透過性素材からなる外被材８の間に入れたが、表面に起伏ができる範囲で、気体吸着デバイス１を芯材７の内側に配置しても同様の効果が得られる。 In this embodiment, the gas adsorption device 1 is placed between the core material 7 and the jacket material 8 made of a gas-impermeable material. The same effect can be obtained by arranging them.

本実施例において、開封部材４は金属製の円柱状の構成としたが、形状はこの限りではなく、例えば実施例２から６に示す形状でもよく、材質も金属ではなく樹脂などであっても良い。 In this embodiment, the unsealing member 4 has a cylindrical structure made of metal, but the shape is not limited to this. good.

以上のように、本発明に係る気体吸着デバイスは、開封部材が有する突起部が、大気圧や真空断熱材の成型時に意図せず開口が作られる可能性を大幅に低減でき、また断熱材の生産時に外れたり、開封部材の位置が変わったりする事が無く、また気体吸着デバイスの開封部材が外被材を破損させるリスクを大幅に低減できる。 As described above, the gas adsorption device according to the present invention can greatly reduce the possibility that the protrusions of the unsealing member are unintentionally opened at atmospheric pressure or during the molding of the vacuum insulation material. There is no possibility that the unsealing member will come off during production or the position of the unsealing member will change, and the risk that the unsealing member of the gas adsorption device will damage the outer covering material can be greatly reduced.

さらには気体吸着デバイス自体を薄くする事が可能になり、真空断熱材の平滑性および真空断熱材の外被材の破壊リスクを低減できる。 Furthermore, the gas adsorption device itself can be made thinner, and the smoothness of the vacuum heat insulating material and the breakage risk of the outer covering material of the vacuum heat insulating material can be reduced.

これにより、断熱性能が優れ、なおかつ経時耐久性に優れる真空断熱材を実現可能である。そして、この真空断熱材により、冷蔵庫、冷凍庫、自動販売機などの保温保冷機器の熱損失の低減だけでなく、住宅などにおいても、電気、ガスなどのエネルギ消費量を低減させることができる。 Thereby, it is possible to realize a vacuum heat insulating material having excellent heat insulating performance and excellent durability over time. This vacuum insulation material not only reduces heat loss in heat and cold insulation equipment such as refrigerators, freezers, and vending machines, but also reduces energy consumption such as electricity and gas in houses.
