Description

保温装置及び配送用保温ボックスThermal insulation device and thermal insulation box for delivery
　本発明は、配送用ボックス内の配送物を所定の温度に維持する保温装置および当該保温装置を備えた配送用保温ボックスに関するものである。 The present invention relates to a heat retaining device that maintains a delivery in a delivery box at a predetermined temperature, and a heat retaining box for delivery including the heat retaining device.
　従来から医薬品や食品などにおいては、品質保持のために所定の温度での配送、運搬が求められてきた。特に医薬品では１０℃以下の維持が厳密に求められている。従来、このような医薬品や食料品等は、大量の保冷剤で配送物を包み保温ボックスに収容して配送、運搬していた。しかし、この方法は、能動的な温度管理とは言えず、急激な温度変化を制御できず、所定の温度より、低い温度、または高い温度になるおそれがあった。 Conventionally, pharmaceuticals and foods have been required to be delivered and transported at a predetermined temperature in order to maintain quality. In particular, pharmaceuticals are strictly required to maintain at 10 ° C. or lower. Conventionally, such medicines and foods have been delivered and transported by wrapping a delivery item with a large amount of a cooling agent and storing it in a heat insulation box. However, this method cannot be said to be active temperature management, and a rapid temperature change cannot be controlled, and there is a possibility that the temperature becomes lower or higher than a predetermined temperature.
　特許文献１では、外気の温度に左右されることなく長時間にわたり、食品、医薬品、血液などを所定の温度範囲に保温（保冷）可能な恒温ボックスについて記載されている。そして、この恒温ボックスでは１３kg以上の蓄冷剤を使用して２５時間５℃付近を維持している。 Patent Document 1 describes a thermostatic box that can keep food, medicine, blood, and the like within a predetermined temperature range for a long time without being influenced by the temperature of the outside air. And in this constant temperature box, 13 kg or more of regenerator is used and maintained at about 5 ° C. for 25 hours.
　特許文献２では、断熱ボックスの内部に予冷室と保冷室とを区画して上下に形成し、予冷室と保冷室とを冷気連通口で連通させているクールボックスについて記載されている。この連通口には開度調整扉が配置され、保冷室内の温度に基づき開閉制御されるようになっている。このクールボックスでは１２kgほどのドライアイスと蓄冷剤を用いて、５５時間１０℃以下を保っている。しかし、このクールボックスは人が手で持ち運びするようなクールボックスではない。また、ドライアイスは、医薬品や食料品を過度に冷却し、凍結させるおそれがあるとともに、航空貨物では危険品扱いとなり、航空便での配送には不向きである。さらにドライアイスは備蓄に特別な設備を要し、一般的には使用する都度購入しなければならない。 Patent Document 2 describes a cool box in which a pre-cooling chamber and a cold-insulating chamber are partitioned and formed vertically in an insulated box, and the pre-cooling chamber and the cold-insulating chamber are communicated with each other through a cold air communication port. An opening adjustment door is disposed at this communication port, and is controlled to be opened and closed based on the temperature in the cold insulation chamber. In this cool box, about 12 kg of dry ice and a cold storage agent are used and maintained at 10 ° C. or lower for 55 hours. However, this cool box is not a cool box that people carry with their hands. In addition, dry ice may cause excessive cooling and freezing of medicines and foodstuffs, and is handled as dangerous goods in air cargo, and is not suitable for delivery by air mail. In addition, dry ice requires special equipment for stockpiling and generally must be purchased each time it is used.

　本発明の保温装置で能動的に温度管理することにより所望の温度範囲を確実に長時間維持することができ、急激な温度変化も制御可能で過度の冷却や高温を回避できる。これにより、配送物の品質の保証が可能であり、温度管理が必要な、医薬品、食料品等の配送において本発明の保温装置は効果を発揮する。特に、医薬品、治験薬、試薬、血液、検体などの厳密な温度維持が求められる物品の配送に優れた効果を有する。
　また、本発明の保温装置により、保冷剤または蓄熱剤の熱量を有効に利用することができ、保冷剤または蓄熱剤の使用量を少なくすることができる。例えば、－２０℃～０℃の保冷剤を４kg使用して配送目的物を２℃～８℃に４０時間以上維持することができる。

(Example 2)
　本発明の保温装置は、遮蔽板、温度センサーおよび可動遮蔽板駆動機構（可動遮蔽板駆動装置）を備えている。
　保温装置が保温ボックスの内部に装填された状態では、遮蔽板は保温ボックス内部を熱源室と温度管理室に仕切って、両室を遮断することができる。
　本発明の保温装置は、温度管理室を所望の温度に維持するものである。本発明の保温装置は、蓄熱剤を使用することにより、温度管理室内を外気温より高温に維持するものであってもよいし、保冷剤を使用することにより、温度管理室内を外気温より低温に維持する（保冷）するものであってもよい。 The heat retaining device of the present invention includes a shielding plate, a temperature sensor, and a movable shielding plate driving mechanism (movable shielding plate driving device).
In a state in which the heat retaining device is loaded inside the heat retaining box, the shielding plate can partition the heat retaining box into a heat source chamber and a temperature control chamber and block both chambers.
The heat retaining device of the present invention maintains the temperature control room at a desired temperature. The heat insulation device of the present invention may be one that maintains the temperature management room at a temperature higher than the outside air temperature by using a heat storage agent, or the temperature inside the temperature management room is lower than the outside air temperature by using a cold insulation agent. It may be maintained (cold).
　遮蔽板には、複数の開口部が設けられている。開口部閉状態では、熱源室と温度管理室の空気の移動は遮断される。また、遮蔽板は断熱部材で構成されており、熱源室の熱は温度管理室には伝導されない。断熱により、配送物の所望の温度範囲外への曝露を回避できる。
　遮蔽板の開口部が開状態のときには、熱源室で冷却された、又は暖められた空気が温度管理室に移動し、温度管理室の温度が所望の温度に保たれる。遮蔽板表面の広範囲に、より好ましくは略全体に複数の開口部が設けられている。広範囲に開口部を設けることにより空気移動を容易にし、温度管理室内の温度を迅速に所望の温度に到達させる。
　開口部の数は２以上であればよい。好ましくは、２～１００、より好ましくは、３～８０、さらに好ましくは、４～６０である。開口部の総面積は遮蔽板の表面積の１０％～５０％、より好ましくは、１５％～４５％、さらに好ましくは２０～４０％である。開口部の総面積が遮蔽板の表面積の１０％未満である場合は、迅速な空気移動が達成されず、温度管理室内の温度を所望の温度に到達させるまでに時間がかかってしまう。また開口部の総面積が遮蔽板の表面積の５０％より大きい場合は、過度な空気移動が行われてしまうため、温度管理室内の温度が所望の温度よりも上昇または低下しすぎる恐れがある。開口部の形は、スリット、円形、楕円形、長方形など形は問わないが、スリットが好ましい。 The shielding plate is provided with a plurality of openings. In the closed state of the opening, the movement of air in the heat source chamber and the temperature control chamber is blocked. Moreover, the shielding board is comprised with the heat insulation member, and the heat | fever of a heat-source room is not conducted to a temperature control room. Thermal insulation can avoid exposing the delivery to outside the desired temperature range.
When the opening of the shielding plate is in the open state, the air cooled or warmed in the heat source chamber moves to the temperature management chamber, and the temperature of the temperature management chamber is maintained at a desired temperature. A plurality of openings are provided over a wide area on the surface of the shielding plate, more preferably substantially over the entire surface. By providing an opening in a wide range, air movement is facilitated, and the temperature in the temperature control chamber is quickly reached to a desired temperature.
The number of openings may be two or more. Preferably, it is 2 to 100, more preferably 3 to 80, still more preferably 4 to 60. The total area of the openings is 10% to 50% of the surface area of the shielding plate, more preferably 15% to 45%, and still more preferably 20 to 40%. When the total area of the openings is less than 10% of the surface area of the shielding plate, rapid air movement is not achieved, and it takes time until the temperature in the temperature control chamber reaches the desired temperature. In addition, when the total area of the openings is larger than 50% of the surface area of the shielding plate, excessive air movement is performed, so that the temperature in the temperature control chamber may be increased or decreased more than the desired temperature. The shape of the opening may be a slit, a circle, an ellipse, a rectangle or the like, but a slit is preferable.
　遮蔽板は少なくとも固定遮蔽板と可動遮蔽板から構成され、ガイド用遮蔽板など他の構成要素を含んでもよい。温度管理室の温度センサーと接続された可動遮蔽板駆動機構により可動遮蔽板はスライドする。可動遮蔽板が温度管理室の温度に基づき自動的にスライドすることにより遮蔽板の複数の開口部が自動的に開閉する。同時に開口部の全部が開閉してもよいし、一部が開閉してもよく、開口率を調節することができる。例えば可動遮蔽板のスライドによる開口部の開閉は、同様の形および数の開口部が固定遮蔽板および可動遮蔽板に設けられている場合、可動遮蔽板がスライドすることにより両者の開口部の重複を調節して行うことがき、この場合開口部の開口率を調節することも可能である。可動遮蔽板駆動機構は温度センサーの感知した温度情報シグナルに基づき、可動遮蔽板を駆動（スライド）し得るものであればいかなるものであってもよい。 The shield plate is composed of at least a fixed shield plate and a movable shield plate, and may include other components such as a guide shield plate. The movable shielding plate slides by the movable shielding plate driving mechanism connected to the temperature sensor in the temperature management room. The movable shield plate automatically slides based on the temperature in the temperature control room, so that the plurality of openings of the shield plate are automatically opened and closed. At the same time, all of the openings may be opened and closed, or some of them may be opened and closed, and the opening ratio can be adjusted. For example, when the opening and closing of the opening by sliding the movable shielding plate is the same shape and number of openings provided in the fixed shielding plate and the movable shielding plate, the opening of both of them is overlapped by sliding the movable shielding plate In this case, it is also possible to adjust the aperture ratio of the opening. The movable shielding plate driving mechanism may be any mechanism that can drive (slide) the movable shielding plate based on the temperature information signal sensed by the temperature sensor.
　固定遮蔽板と可動遮蔽板は断熱部材からなる。断熱部材としては、例えば、塩化ビニル、発泡スチロール、発泡塩化ビニル等が挙げられる。固定遮蔽板と可動遮蔽板は同じ断熱部材からなるものであってもよいし、異なる断熱部材からなるものであってもよい。固定遮蔽板と可動遮蔽板を構成する断熱部材としては、遮熱能力に加えて、耐久性、加工性等から発泡塩化ビニルを用いることが好ましい。断熱部材が発泡塩化ビニルである場合は、発泡倍率が約２倍程度であることが好ましい。発泡倍率とは、下記の式より得られるものである。
（式）発泡倍率＝（発泡前の原料塩化ビニルの密度）／（発泡後の塩化ビニル発泡体の見掛け密度）
　また断熱部材の比重は、JIS規格番号JISK7112「プラスチック－非発泡プラスチックの密度及び比重の測定方法」に基づいて測定した値が、0.5～0.9、好ましくは0.6～0.8である。 The fixed shielding plate and the movable shielding plate are made of heat insulating members. Examples of the heat insulating member include vinyl chloride, polystyrene foam, and foamed vinyl chloride. The fixed shielding plate and the movable shielding plate may be made of the same heat insulating member, or may be made of different heat insulating members. As the heat insulating member constituting the fixed shielding plate and the movable shielding plate, it is preferable to use foamed vinyl chloride from the viewpoint of durability, workability and the like in addition to the heat shielding ability. When the heat insulating member is foamed vinyl chloride, the foaming ratio is preferably about twice. The expansion ratio is obtained from the following formula.
(Formula) Foaming ratio = (density of raw material vinyl chloride before foaming) / (apparent density of foamed vinyl chloride)
The specific gravity of the heat insulating member is 0.5 to 0.9, preferably 0.6 to 0.8, as measured based on JIS standard number JIS K7112 “Plastics—Method of measuring density and specific gravity of non-foamed plastic”.
　また、固定遮蔽板と可動遮蔽板の厚さは、５～２０mm、好適には６～１２mmである。固定遮蔽板および可動遮蔽板の厚さが５mm未満であると遮熱能力や耐過重性などの耐久性に問題があり、２０mmより厚い場合は熱源室や温度管理室の体積が小さくなってしまい、配送物の大きさや保冷剤等の量が限定されてしまうという問題がある。 The thickness of the fixed shielding plate and the movable shielding plate is 5 to 20 mm, preferably 6 to 12 mm. If the thickness of the fixed shielding plate and the movable shielding plate is less than 5 mm, there is a problem in durability such as heat shielding ability and overload resistance. If it is thicker than 20 mm, the volume of the heat source room and the temperature control room becomes small. There is a problem that the size of the delivery item and the amount of the cooling agent are limited.
　本発明の保温装置を用いて配送物を航空貨物として配送するためには、駆動力は好ましくは乾電池により配給される。スライド機構は開き戸式扉機構と比較して、温度管理室の体積を最大に確保でき、より大きな配送物の収納を可能にする。また、空気の遮断効果も高い。 In order to deliver a delivery as an air cargo using the heat retaining device of the present invention, the driving force is preferably distributed by dry batteries. Compared with the hinged door mechanism, the slide mechanism can secure the maximum volume of the temperature control room and can accommodate larger deliveries. In addition, the air blocking effect is high.
　本発明の保温装置は配送時に保温ボックス中に備えられて持ち運びするものであることより、軽いものが好ましい。１kg～８kgであれば好適であり、２kg～５kgであればより好適である。 The light insulation device of the present invention is preferably light because it is provided in a heat insulation box and carried at the time of delivery. 1 kg to 8 kg is preferable, and 2 kg to 5 kg is more preferable.
　温度管理室の温度を迅速正確に測定するために、温度センサーは、好ましくは熱伝導率のよい材料に付着させて温度管理室に備えられる。好ましい材料はアルミニウムや銅である。好適には、温度センサーはアルミニウム管や銅管に接着されて備えられる。 In order to quickly and accurately measure the temperature of the temperature control room, the temperature sensor is preferably attached to a material having good thermal conductivity and provided in the temperature control room. Preferred materials are aluminum and copper. Preferably, the temperature sensor is provided by being bonded to an aluminum tube or a copper tube.
　可動遮蔽板駆動機構は、予め定められた温度で可動遮蔽板をスライドさせて遮蔽板の開口部を開にする。また、別の予め定められた温度で可動遮蔽板をスライドさせて遮蔽板の開口部を閉にする。温度管理室の温度を２℃～８℃に維持したい場合は、この２℃～８℃の間で駆動機構が動く２つの温度を設定する。この場合、駆動機構が動く温度の一方は６℃～８℃であり、他方が４℃～６℃であることが好ましく、さらに一方が７℃であり、他方が５℃であることが好ましい。例えば冷却することにより温度管理室の温度を２℃～８℃に維持したい場合は、開口部を開にする温度が７℃であり、開口部を閉にする温度が５℃である。 The movable shield driving mechanism slides the movable shield at a predetermined temperature to open the opening of the shield. Further, the movable shield plate is slid at another predetermined temperature to close the opening of the shield plate. When it is desired to maintain the temperature of the temperature control room at 2 ° C. to 8 ° C., two temperatures at which the drive mechanism moves are set between 2 ° C. and 8 ° C. In this case, one of the temperatures at which the drive mechanism moves is 6 ° C. to 8 ° C., the other is preferably 4 ° C. to 6 ° C., one is 7 ° C., and the other is preferably 5 ° C. For example, when it is desired to maintain the temperature of the temperature control room at 2 ° C. to 8 ° C. by cooling, the temperature for opening the opening is 7 ° C., and the temperature for closing the opening is 5 ° C.
　本発明の保温装置は、保温ボックス内に装填され、熱源室と温度管理室を形成させる。本発明の保温装置は、専用の保温ボックスと組合わせて使用することができる。また、市販の保温ボックスと組合わせて使用してもよい。保温ボックスは、限定されるものではないが、長時間所望の温度範囲を維持するためには、断熱効果の高い保温ボックスが好ましい。例えば、断熱剤として、発泡スチロール、発泡ウレタン、発泡塩化ビニルを用いた保温ボックスが挙げられ、六面真空断熱パネルによる保温ボックスは軽くて断熱効果が高い好適な保温ボックスである。 The heat retaining device of the present invention is loaded in a heat retaining box to form a heat source chamber and a temperature control chamber. The heat retaining device of the present invention can be used in combination with a dedicated heat retaining box. Moreover, you may use it combining with a commercially available heat retention box. Although the heat insulation box is not limited, in order to maintain a desired temperature range for a long time, a heat insulation box with a high heat insulation effect is preferable. For example, a heat insulation box using foamed polystyrene, foamed urethane, or foamed vinyl chloride is used as the heat insulating agent, and the heat insulation box using a six-sided vacuum heat insulation panel is light and has a high heat insulation effect.
　保温装置が保温ボックス内に装填された状態では、遮蔽板により保温ボックス内部を熱源室と温度管理室に区切ることにより、熱源室と温度管理室が形成される。保温装置は保温ボックス内に装填可能な大きさであればよい。熱源室と温度管理室の形成は、遮断板により分離されていればいかなる態様であってもよい。保温ボックスが箱状である場合には例えば以下のような態様が例示される。 In a state where the heat insulation device is loaded in the heat insulation box, the heat source room and the temperature management room are formed by dividing the heat insulation box interior into the heat source room and the temperature management room by the shielding plate. The heat retaining device may be of a size that can be loaded into the heat retaining box. The heat source chamber and the temperature control chamber may be formed in any form as long as they are separated by the shielding plate. When the heat insulation box is box-shaped, for example, the following modes are exemplified.
（１）１つの遮断板の周縁４辺が保温ボックス室内の４つの壁面に密着することにより、保温ボックス内の空間を上下または左右に分離する態様。
　上記態様において保温ボックス内の空間を上下に分離する場合は、遮断板の平面に対して垂直方向に２以上の脚部が連結されていることが好ましい。脚部は本発明の目的を達成し得るものであれば、いかなる形状、材質であってもよい。 (1) A mode in which the space in the heat insulation box is separated into the top and bottom or the left and right by the four peripheral edges of one blocking plate being in close contact with the four wall surfaces in the heat insulation box.
In the above aspect, when the space in the heat insulation box is separated vertically, it is preferable that two or more legs are connected in a direction perpendicular to the plane of the shielding plate. The leg may be any shape and material as long as the object of the present invention can be achieved.
（２）遮断板の平面に対して垂直方向に２つ以上（例えば４つ）の壁体が、遮断板に連結しており、これらの壁体と、保温ボックス室内の１つ以上の壁面（底面や側面）とが協働して、保温ボックス内において遮断板により分離された空間を形成する態様。
　上記態様においては、遮断板に連結した壁体は熱源室と温度管理室とを遮断するものであるため、遮断板の構成要素とみなすことができる。遮断板に連結した壁体は、断熱部材により構成されている。 (2) Two or more (for example, four) wall bodies perpendicular to the plane of the shield plate are connected to the shield plate, and these wall bodies and one or more wall surfaces in the heat insulation box chamber ( A mode in which the bottom surface and the side surface) cooperate to form a space separated by a blocking plate in the heat insulation box.
In the said aspect, since the wall body connected with the interruption | blocking board interrupts | blocks a heat-source room and a temperature control room, it can be considered as a component of an interruption | blocking board. The wall body connected to the blocking plate is constituted by a heat insulating member.
　上記（１）および（２）の態様において、遮断板における脚部もしくは壁体の連結は、本発明の目的を達成し得るものであればいかなる状態であってもよく、取り外しが可能であってもよいし、取り外しが不可能であってもよい。 In the above aspects (1) and (2), the connection of the leg portion or the wall body in the blocking plate may be in any state as long as the object of the present invention can be achieved, and can be removed. Alternatively, it may be impossible to remove.
　保温ボックスは一人で持ち運びできる大きさ、重量であることが好ましい。
　限定されるものではないが、保温ボックスの内容量は、好ましくは５L～５０L、より好ましくは１０L～４０L、さらに好ましくは、１５～３０Lである。また、保温ボックスの外形寸法は、幅が300～600mm、好ましくは350mm～500mm、より好ましくは400～450mmであり、奥行きと高さが200～400mm、好ましくは250mm～350mm、より好ましくは300～330mmである。
　保温装置、保温ボックスおよび熱源室に収納される保冷剤または蓄熱剤を合計した総重量は、保冷剤もしくは蓄熱材の性能により変わるが、６kg～２０kgが好ましく、８～１５kgがより好ましい。現状技術においては総重量６kg未満では所望の保冷もしくは保温効果を得ることが難しいと考えられる。総重量が２０kgより重い場合は、配送者一人での持ち運びが困難である。 It is preferable that the heat insulation box has a size and weight that can be carried by one person.
Although not limited, the internal volume of the heat retaining box is preferably 5 L to 50 L, more preferably 10 L to 40 L, and still more preferably 15 to 30 L. The external dimensions of the heat insulation box are 300 to 600 mm in width, preferably 350 to 500 mm, more preferably 400 to 450 mm, and 200 to 400 mm in depth and height, preferably 250 to 350 mm, more preferably 300 to 330mm.

In the current technology, it is considered that it is difficult to obtain a desired cold or warming effect if the total weight is less than 6 kg. When the total weight is heavier than 20 kg, it is difficult for the delivery person to carry.
　本発明はさらに、保温装置を備えた配送用保温ボックスに関する。
　本発明の保温ボックスは、内部に保温装置が固定されて備えられていても、取り外し可能に備えられていてもよい。配送物を収納する時に、保温装置が保温ボックス内にその都度装填されてもよい。
　本発明の配送用保温ボックスは、遮蔽板により仕切られた熱源室と温度管理室を備える。
　保温ボックスの材質、大きさ、重量については、前述したとおりである。 The present invention further relates to a heat retaining box for delivery provided with a heat retaining device.
The heat retaining box of the present invention may be provided with a heat retaining device fixed therein or detachably. When storing the delivery item, the heat insulating device may be loaded into the heat insulating box each time.
The heat retaining box for delivery of the present invention includes a heat source chamber and a temperature control chamber partitioned by a shielding plate.
The material, size, and weight of the heat insulation box are as described above.
　さらに本発明は、保温装置を備えた配送用保温ボックスに、配送物、並びに保冷剤または蓄熱剤を梱包することを特徴とする配送物の保温方法に関する。保冷剤としては好ましくはゲルおよび／または液体を内包する保冷剤である。
　熱源室には、保冷剤または蓄熱剤をそのまま、または紙や布に包んでから収納する。所望の維持温度が外気温より低いときは保冷剤を、配送物の所望の維持温度が外気温より高いときは蓄熱剤を収納する。たとえば、配送物の所望の維持温度が２～８℃である場合でも、極寒地であれば、凍結を避けるために蓄熱剤を収納する。
　保冷剤または蓄熱剤の量、態様は外気温、所望の温度範囲、所望の温度維持時間に応じて決定される。外気温と所望の温度が離れている場合は、保冷剤または蓄熱剤の量を増加する。好ましい量として例示されるのは、１～８kg、より好ましくは、２～６kg、より好ましくは、３～５kgの量である。
　保冷剤および蓄熱剤の種類は限定されるものではない。長時間温度管理が必要な場合や、外気温と所望の温度が離れている場合は、高性能であるものが好ましいが、一般に市販されている保冷剤でもよい。例えば、熱源室に収納される保冷剤は、－５０℃～０℃のもの、好ましくは－２０～－５℃のものを使用することができるが、現状技術では－５℃～０℃程度のものを容易に使用することができる。 Furthermore, the present invention relates to a method for keeping warm of a delivery item, wherein the delivery item and a cold insulation agent or a heat storage agent are packaged in a delivery heat insulation box provided with a thermal insulation device. The cryogen is preferably a cryogen containing a gel and / or liquid.
In the heat source chamber, the cold insulating agent or the heat storage agent is stored as it is or after being wrapped in paper or cloth. When the desired maintenance temperature is lower than the outside air temperature, the refrigerant is stored. When the desired maintenance temperature of the delivery is higher than the outside air temperature, the heat storage agent is contained. For example, even when the desired maintenance temperature of the delivery is 2 to 8 ° C., the heat storage agent is stored in order to avoid freezing in an extremely cold region.
The amount and mode of the cold insulating agent or the heat storage agent are determined according to the outside air temperature, a desired temperature range, and a desired temperature maintenance time. When the outside air temperature and the desired temperature are different from each other, the amount of the refrigerant or the heat storage agent is increased. Examples of preferred amounts are 1 to 8 kg, more preferably 2 to 6 kg, more preferably 3 to 5 kg.
The kind of the cold insulating agent and the heat storage agent is not limited. When temperature control is required for a long time or when the outside air temperature and the desired temperature are separated from each other, those having high performance are preferable, but commercially available cryogens may be used. For example, the cryogen stored in the heat source chamber may be -50 ° C to 0 ° C, preferably -20 ° C to -5 ° C, but the current state of technology is about -5 ° C to 0 ° C. Things can be used easily.
　さらに、温度管理室には加熱装置が備えられていてもよい。加熱装置は、温度管理室内の温度を上昇させるためのものであり、温度管理室の過冷却を防止する。例えば外気温が－２５℃～０℃の寒冷地において本発明の保温装置および保温ボックスを使用する場合に温度管理室に加熱装置を備えることが好ましい。加熱装置は、本発明の保温装置もしくは保温ボックスと接続して設けられていてもよいし、別個に温度管理室に設置されてもよい。加熱装置は温度管理室の温度を感知する温度センサーと、温度管理室内に熱を放射する加熱プレートと、加熱プレートを加熱するヒーターとを担持するものが好適である。加熱プレート自体が温度センサーの機能を有していてもよいし、温度センサーが加熱プレートと別個に設けられていてもよい。加熱プレート自体が温度センサーの機能を有する場合は、加熱装置を小さくすることができ、温度管理室の空間を有効に利用することができる。 Furthermore, the temperature control room may be equipped with a heating device. The heating device is for increasing the temperature in the temperature control room and prevents overcooling of the temperature control room. For example, in the case where the heat retaining device and the heat retaining box of the present invention are used in a cold region where the outside air temperature is −25 ° C. to 0 ° C., it is preferable to provide a heating device in the temperature control room. The heating device may be provided in connection with the heat retaining device or the heat retaining box of the present invention, or may be separately installed in the temperature management room. The heating device preferably has a temperature sensor that senses the temperature of the temperature control room, a heating plate that radiates heat into the temperature control room, and a heater that heats the heating plate. The heating plate itself may have the function of a temperature sensor, or the temperature sensor may be provided separately from the heating plate. When the heating plate itself has the function of a temperature sensor, the heating device can be made small, and the space in the temperature control room can be used effectively.
　ヒーターは温度センサーと接続されており、ヒーターが加熱プレートの温度を上昇させ、加熱プレートから熱が放射することにより、温度管理室の温度が上昇する。ヒーターは、加熱装置の温度センサーが得た温度管理室の温度情報シグナルに基づき駆動、あるいは、停止する。温度管理室の温度を２℃～８℃に維持したい場合は、この２℃～８℃の間で加熱装置の稼働もしくは停止となる２つの温度を設定する。例えば加熱装置が停止する温度を５℃～７℃、加熱装置が開始する温度を２～４℃とすることが好ましい。本発明の保温装置を用いて配送物を航空貨物として配送するためには、ヒーターの駆動力は好ましくは乾電池により配給される。 The heater is connected to the temperature sensor, and the heater raises the temperature of the heating plate, and heat is radiated from the heating plate, thereby raising the temperature of the temperature control room. The heater is driven or stopped based on the temperature information signal of the temperature control room obtained by the temperature sensor of the heating device. If it is desired to maintain the temperature in the temperature control room at 2 ° C. to 8 ° C., two temperatures between the 2 ° C. and 8 ° C. at which the heating device is activated or stopped are set. For example, the temperature at which the heating device stops is preferably 5 ° C. to 7 ° C., and the temperature at which the heating device starts is preferably 2 to 4 ° C. In order to deliver deliveries as air cargo using the heat retaining device of the present invention, the driving force of the heater is preferably delivered by dry batteries.
　また温度管理室に加熱装置を設ける場合、熱源室に収納するものは保冷剤であっても、蓄熱剤であってもよいが、保冷剤が好ましい。熱源室の冷却された空気と、温度管理室の加熱装置により、外気温が低い寒冷地で使用する場合であっても、温度管理室内の温度を所望の温度に維持することが可能となる。 Further, when a heating device is provided in the temperature control room, what is stored in the heat source room may be a cold storage agent or a heat storage agent, but a cold storage agent is preferable. The temperature in the temperature control chamber can be maintained at a desired temperature by using the cooled air in the heat source chamber and the heating device in the temperature control chamber even when used in a cold region where the outside air temperature is low.
　本発明の保温方法は、好ましくは配送物を内箱に収納してから保温ボックスに収納する。内箱は断熱効果を有する箱が好ましく、例えば、段ボウル箱などが安価で使い易く好適である。さらに好ましくは、内箱の内部に保冷剤または蓄熱剤を配置する。内箱の内部の保冷剤または蓄熱剤は、配送物の所望の温度と略同一の温度であることが好ましい。この内部の保冷剤または蓄熱剤が配送物の近くに存在することにより配送物が所望の温度をより長く保つことができる。また配送物もしくは内箱に収納した配送物を、さらに断熱効果を有するパネルで覆ってもよい。断熱効果を有するパネルは、いかなるものであってもよいが、材質が紙であれば焼却して廃棄することが可能であり、取扱いが容易である。断熱効果を有するパネルを用いることにより、寒冷地で本発明の保温ボックスを使用する際に温度管理室内の温度をより効率よく所望の温度に維持することが可能となる。 In the heat insulation method of the present invention, the delivery item is preferably stored in the inner box and then stored in the heat storage box. The inner box is preferably a box having a heat insulating effect. For example, a corrugated bowl box is inexpensive and easy to use. More preferably, a cooling agent or a heat storage agent is disposed inside the inner box. It is preferable that the cooling agent or the heat storage agent inside the inner box has a temperature substantially the same as the desired temperature of the delivery. The presence of the internal cold insulation or heat storage agent near the delivery allows the delivery to keep the desired temperature longer. Further, the delivery item or the delivery item stored in the inner box may be further covered with a panel having a heat insulating effect. The panel having a heat insulating effect may be any panel, but if the material is paper, it can be incinerated and discarded, and is easy to handle. By using a panel having a heat insulating effect, the temperature in the temperature control room can be more efficiently maintained at a desired temperature when the heat retaining box of the present invention is used in a cold region.
