　このうち、第１の箱１０は、図１，３に示すように、前記した３つの箱１０，２０，３０の中で最も小さいな箱であり、物品Ｍを直接入れる箱となっている。ここでは、第１の箱１０は、下部に位置する第１の箱本体部１１と、上部に位置する第１の箱蓋部１２で構成されており、この第１の箱本体部１１と第１の箱蓋部１２とが嵌合することにより、内部が略密閉状態となるように構成されている。 Of these, the first box 10 is the smallest box among the three boxes 10, 20, and 30 described above, as shown in FIGS. Here, the first box 10 is composed of a first box main body 11 positioned at the bottom and a first box cover 12 positioned at the top. The inside is configured to be in a substantially sealed state by fitting with the box lid portion 12 of 1 .
　また、第１の箱本体部１１と第１の箱蓋部１２を構成する部材は、図５に示すように、それぞれ基材１３とコーティング層１４とを有するものとなっている。具体的には、この実施の形態の基材１３は、合成樹脂、特に発泡合成樹脂で形成されている。合成樹脂としては、ポリスチレン、ポリエチレン、ポリプロピレンおよびポリウレタンから選択された１以上の材料で形成されているものが挙げられ、発泡合成樹脂としては、これらの合成樹脂中に微細な気泡を分散させたものを指すものである。ここでは、基材１３として、発泡スチロール（発泡ポリスチレン）を用いている。 Also, the members constituting the first box body 11 and the first box lid 12 each have a base material 13 and a coating layer 14, as shown in FIG.

Examples of such synthetic resins include one or more resins selected from the group consisting of polycarbonate resins, polyethylene resins, polyolefin resins, polyester resins, acrylic resins, polyamide resins, polystyrene resins, ABS resins, and acetal resins. What is formed is mentioned.
　また、コーティング層１４は、基材１３に施したコーティングであり、具体的には、断熱効果を有するポリウレア樹脂をコーティングしたポリウレア樹脂層で形成されている。ポリウレア樹脂のコーティング層１４は少なくとも基材１３の外面に施されており、ここでは、基材１３の外面及び内面を含む全面（表面全て）にポリウレア樹脂層のコーティング層１４が施されている。後述するように、この実施の形態の第１の箱蓋部１２には、上面から下面まで貫通する孔部１５が形成されているが、この孔部１５の壁面にも全てコーティング層１４が施されている。これにより、ポリウレア樹脂の断熱効果をより効果的に発揮することができるものである。 Also, the coating layer 14 is a coating applied to the base material 13, and specifically, it is formed of a polyurea resin layer coated with a polyurea resin having a heat insulating effect. The polyurea resin coating layer 14 is applied to at least the outer surface of the base material 13, and here, the polyurea resin coating layer 14 is applied to the entire surface (entire surface) including the outer surface and the inner surface of the base material 13. As will be described later, the first box cover 12 of this embodiment is formed with a hole 15 penetrating from the top surface to the bottom surface. It is Thereby, the heat insulating effect of the polyurea resin can be exhibited more effectively.

Examples of polyurea resins include those formed by reacting polyisocyanates and polyamines.
　また、基材１３及びコーティング層１４の厚さは、断熱効果を発揮できるように、適宜決定すれば良い。 Also, the thicknesses of the base material 13 and the coating layer 14 may be appropriately determined so that the heat insulating effect can be exhibited.
　なお、ここでは、例として、Ｌ２２９×Ｗ２２９×Ｈ４０ｍｍ、基材厚さ１０ｍｍ、外面コーティング１ｍｍ、内面コーティング０．５ｍｍの箱を用いているが、これに限るものではない。 Here, as an example, a box of L229×W229×H40 mm, base material thickness of 10 mm, outer surface coating of 1 mm, and inner surface coating of 0.5 mm is used, but it is not limited to this.
　また、図５に示すように、第１の箱１０内には保冷手段としてのドライアイス４０が配置されている。この実施の形態では、粒状のドライアイス４０が２０ｋｇ配置されているが、これに限るものではなく、板状等の別形状のドライアイスを用いても良いし、配置する量も状況によって適宜変更すれば良い。また、保冷手段としてはドライアイス以外の他の手段、例えば、第１の箱１０に所定の導入孔を設けて、当該導入孔を介して外部に設けられた冷風装置から第１の箱１０内に冷気を送る等であっても良く、適切な温度に保冷される適宜の手段が用いられれば良い。ここでは、物品Ｍはワクチンであって、保冷手段４０によって、一定期間、約―２５℃、又は、約－７０℃に保持されるように構成されている。 In addition, as shown in FIG. 5, dry ice 40 as a cold insulation means is placed inside the first box 10 .

It is also possible to send cold air to the inside of the container, and it is sufficient to use an appropriate means for keeping the temperature at an appropriate temperature. Here, the article M is a vaccine, and is configured to be kept at approximately -25°C or approximately -70°C for a certain period of time by the cooling means 40 .
　また、第２の箱２０は、図１，３に示すように、前記した３つの箱１０，２０，３０の中で２番目に小さい箱であり、第１の箱１０を入れるような大きさ及び形状の箱となっている。ここでは、第２の箱２０は、下部に位置する第２の箱本体部２１と、上部に位置する第２の箱蓋部２２で構成されており、この第２の箱本体部２１と第２の箱蓋部２２とが嵌合することにより、内部が略密閉状態となるように構成されている。 1 and 3, the second box 20 is the second smallest box among the three boxes 10, 20 and 30, and is large enough to contain the first box 10. And it is a box of shape. Here, the second box 20 is composed of a second box main body 21 positioned at the bottom and a second box cover 22 positioned at the top. 2 is fitted with the box lid portion 22, the inside is configured to be in a substantially airtight state.
　また、第２の箱本体部２１と第２の箱蓋部２２を構成する部材は、図４に示すように、真空断熱構造を有する真空断熱材で構成されている。具体的には、グラスウールを真空処理したＶＩＰ材２３とその周りに配置された樹脂材２４（ここではポリスチレンフォーム）、その周りに配置された第１のアルミシート２５とを有する構成の板状部材２６を備えており、さらにそれらを箱形状に組んだ上から第２のアルミシート２７で覆うような構成となっている。なお、真空断熱材としては、同様の真空断悦構造、作用効果を有するものであれば、適宜のものを使用すれば良い。 Also, the members forming the second box main body 21 and the second box lid 22 are made of a vacuum heat insulating material having a vacuum heat insulating structure, as shown in FIG. Specifically, a plate-shaped member having a VIP material 23 obtained by vacuum-processing glass wool, a resin material 24 (here, polystyrene foam) arranged around it, and a first aluminum sheet 25 arranged around it. 26, which are assembled into a box shape and covered with a second aluminum sheet 27 from above. As the vacuum heat insulating material, any suitable material may be used as long as it has the same vacuum insulation structure and effect.
　また、ここでは、例として、Ｌ２４４×Ｗ２４４×Ｈ５５ｍｍ、厚さ３０ｍｍの箱を用いているが、これに限るものではない。 Also, here, as an example, a box of L244×W244×H55 mm and a thickness of 30 mm is used, but it is not limited to this.
　また、この実施の形態では、図５に示すように、第１の箱１０の内部温度を測定する測定装置（センサ）６０が設けられている。ここでは、第２の箱蓋部２２の表面（上面）に測定装置を配設する設置部としての凹部２８が設けられており、ここに設置された測定装置６０から延びた測定部５０を、第２の箱２０の第２の箱本体部２１と第２の箱蓋部２２との間の隙間を通して第１の箱蓋部１１に設けられた孔部１５を介して第１の箱１０の内部に挿入させて、内部温度を測定するようになっている。 Also, in this embodiment, as shown in FIG. 5, a measuring device (sensor) 60 for measuring the internal temperature of the first box 10 is provided. Here, a concave portion 28 is provided on the surface (upper surface) of the second box lid portion 22 as an installation portion for arranging the measuring device, and the measuring portion 50 extending from the measuring device 60 installed here is The first box 10 passes through the hole 15 provided in the first box lid 11 through the gap between the second box body 21 and the second box lid 22 of the second box 20. It is designed to be inserted inside to measure the internal temperature.
　また、この実施の形態では、測定装置６０による測定結果をリアルタイムで外部の受信装置に送信する通信装置７０を有している。ここでは、測定装置６０と一体になって構成されている。なお、通信装置７０を第２の箱２０の第２の箱蓋部２２の表面側に配置すると、その上に後述する第３の箱３０の第３の箱蓋部３２が存在することになるため、当該蓋部３２の素材によっては通信電波が届き難くなるという不具合を起こす場合があるが、後述するように第３の箱蓋部３２は、第１の箱１０と同様の基材３３とポリウレア樹脂のコーティング層３４で形成されており、特にポリウレア樹脂は電波を良好に通すことが実証されているので良好な通信環境が補償されるものである。また、ここでは測定装置６０による測定結果を通信装置７０からリアルタイムで外部に送信するようになっていたが、これに限るものではなく、一定時間毎に送信するようになっていても良い。また、通信装置７０を有していないとき、または何らかの障害があって通信環境が整わない場合等には、測定結果を測定装置６０内に保存しておき、その後、取り出すようにすることもあり得る。また、第３の箱３０の外面等の、測定装置６０から有線で繋げる箇所に測定結果を表示する表示装置を配置するようになっていても良い。 In addition, this embodiment has a communication device 70 that transmits the measurement result of the measuring device 60 to an external receiving device in real time. Here, it is configured integrally with the measuring device 60 . If the communication device 70 is arranged on the surface side of the second box lid portion 22 of the second box 20, the third box lid portion 32 of the third box 30, which will be described later, is present thereon. Therefore, depending on the material of the lid portion 32, there may be a problem that it is difficult for communication radio waves to reach. It is formed of the coating layer 34 of polyurea resin, and polyurea resin in particular has been proven to pass radio waves well, so a good communication environment is guaranteed. Also, here, the measurement results of the measurement device 60 are transmitted from the communication device 70 to the outside in real time, but the transmission is not limited to this, and may be transmitted at regular time intervals. In addition, when the communication device 70 is not provided, or when the communication environment cannot be established due to some kind of failure, the measurement results may be stored in the measurement device 60 and then taken out. obtain. Also, a display device for displaying the measurement results may be arranged at a place, such as the outer surface of the third box 30, which is connected from the measuring device 60 by wire.

It is a box of Here, the third box 30 is composed of a third box main body 31 positioned at the bottom and a third box cover 32 positioned at the top. 3 is fitted with the box lid portion 32, the inside is configured to be in a substantially airtight state.
　また、第３の箱本体部３１と第３の箱蓋部３２を構成する部材は、図５に示すように、それぞれ基材３３とポリウレア樹脂のコーティング層３４とを有するものとなっている。このポリウレア樹脂のコーティング層３４は、前記したコーティング層１４と同様に、少なくとも基材３３の外面に施されており、ここでは、基材３３の外面及び内面を含む全面（表面全て）にポリウレア樹脂層のコーティング層３４が施されている。 Also, as shown in FIG. 5, the members forming the third box body 31 and the third box lid 32 each have a base material 33 and a coating layer 34 of polyurea resin. The polyurea resin coating layer 34 is applied to at least the outer surface of the base material 33 in the same manner as the coating layer 14 described above. A layer coating layer 34 is applied.
　なお、基材３３及びコーティング層３４は、前記した第１の箱１０の基材１３及びコーティング層１４と同様の構成であるため、その他の説明を省略する。また、基材３３及びコーティング層３４の厚さは、断熱効果を発揮できるように、適宜決定すれば良く、基材１３及びコーディング層１４と同様であっても良いし、基材１３及びコーディング層１４と異ならせても良い。 Note that the base material 33 and the coating layer 34 have the same configurations as the base material 13 and the coating layer 14 of the first box 10 described above, so other explanations are omitted. In addition, the thicknesses of the base material 33 and the coating layer 34 may be appropriately determined so as to exhibit a heat insulating effect, and may be the same as those of the base material 13 and the coating layer 14, or the thicknesses of the base material 13 and the coating layer 14 may be different.
　また、ここでは、例として、Ｌ４８３×Ｗ４８３×Ｈ３９４ｍｍ、基材厚さ３０ｍｍ、外面コーティング２ｍｍ、内面コーティング０．５ｍｍの箱を用いているが、これに限るものではない。 Also, here, as an example, a box of L483×W483×H394 mm, base material thickness of 30 mm, outer surface coating of 2 mm, and inner surface coating of 0.5 mm is used, but it is not limited to this.
　なお、図２に示すように、この第３の箱３０には、箱を閉じたあとで、開かないように止める、留め具３５が設けられている。ここでは、留め具３５として、長さを調整して第１の箱１０が開かないように保持するベルト状の留め具３５が設けられているが、これに限るものではなく、適宜のもので閉状態を保持するようになっていれば良い。 As shown in FIG. 2, this third box 30 is provided with a fastener 35 that prevents the box from opening after it is closed. Here, as the fastener 35, a belt-like fastener 35 is provided that adjusts the length and holds the first box 10 so that it does not open. It is sufficient if the closed state is maintained.
