Description

本発明は、真空断熱材から構成された断熱容器に係り、その断熱容器を使用しての食品の運搬方法に関するものである。   The present invention relates to a heat insulating container composed of a vacuum heat insulating material, and relates to a method for transporting food using the heat insulating container.

近年、食品の普及に伴い、断熱を必要とする冷凍食品、冷蔵食品や常温で保存を要する常温保存食品が、多数存在する。また、それら食品を、例えば半日間、その温度帯で保存したり運搬したりするニーズも存在する。これらの食品を半日間保存する場合、庫内がそれぞれの温度帯の保冷庫に保存し、運搬する場合、コンテナ内がそれぞれの温度帯の配送車で運搬していた。   In recent years, with the spread of foods, there are a large number of frozen foods that require heat insulation, refrigerated foods, and cold-preserved foods that need to be stored at room temperature. There is also a need to store and transport these foods in that temperature range, for example, for half a day. When these foods are stored for half a day, the interior of the container is stored in a refrigerator in each temperature zone, and when the food is transported, the container is transported by a delivery vehicle in each temperature range.

しかし、この場合、庫内及びコンテナ内を一定の温度に電力により維持しなくてはならないため、電気代がかかると同時に保冷庫や配送車のリース料金が高い。   However, in this case, since the inside of the container and the inside of the container must be maintained at a constant temperature by electric power, an electricity bill is charged and at the same time the lease fee for the cold storage and the delivery vehicle is high.

また、これを解決する手段として、断熱容器に、発泡ポリスチレンや硬質発泡ウレタンフォームなどの簡易な断熱材を用い、チャックや面ファスナなどを用いて蓋の開閉を行うものが多用されている。   As a means for solving this problem, a heat insulating container that uses a simple heat insulating material such as foamed polystyrene or rigid foamed urethane foam and that uses a chuck or a hook and loop fastener to open and close the lid is often used.

しかし、このような断熱容器は、断熱材の初期熱伝導率が高く断熱性能に劣り、しかも、保管に嵩張る傾向がある。このため、断熱性能を向上させた折り畳み可能な断熱容器が開発された（特許文献１参照）。   However, such a heat insulating container has a high initial thermal conductivity of the heat insulating material, is inferior in heat insulating performance, and tends to be bulky in storage. For this reason, a foldable heat insulating container with improved heat insulating performance has been developed (see Patent Document 1).

図９は、特許文献１に開示された断熱容器１００を示す斜視図である。特許文献１に開示された断熱容器１００は、柔軟性を有する外袋１０１および内袋１０３と、真空断熱パネル１０２で構成される。外袋１０１は、底面と４つの側面の計５面が略直方体に縫製され、側面から底面を経て対向する側面に渡ってベルト１０５が掛けられている。また、外袋１０１の上部一辺には蓋部１０４が縫製され、外袋１０１の底部と蓋部１０４の内部には、予め真空断熱パネルが設けられている。   FIG. 9 is a perspective view showing the heat insulating container 100 disclosed in Patent Document 1. FIG. The heat insulating container 100 disclosed in Patent Document 1 includes a flexible outer bag 101 and inner bag 103 and a vacuum heat insulating panel 102. The outer bag 101 has a bottom surface and four side surfaces, a total of five surfaces sewn in a substantially rectangular parallelepiped shape, and a belt 105 is hung from the side surface to the opposite side surface through the bottom surface. A lid 104 is sewn on the upper side of the outer bag 101, and a vacuum heat insulation panel is provided in advance in the bottom of the outer bag 101 and the inside of the lid 104.

使用に際しては、外袋１０１の４つの側面に沿って４枚の断熱パネル１０２を挿入し、断熱パネル１０２の面ファスナ１１１を、外袋１０１の面ファスナ１１０に係合させる。更に、内袋１０３を断熱パネル１０２の装着された外袋１０１の内部に挿入し、内袋１０３の面ファスナ１１２を、断熱パネル１０２の面ファスナ１１１に係合させて組み立てられる。   In use, four heat insulation panels 102 are inserted along the four side surfaces of the outer bag 101, and the surface fasteners 111 of the heat insulation panel 102 are engaged with the surface fasteners 110 of the outer bag 101. Further, the inner bag 103 is inserted into the outer bag 101 to which the heat insulating panel 102 is attached, and the surface fastener 112 of the inner bag 103 is engaged with the surface fastener 111 of the heat insulating panel 102 for assembly.

組み立てられた断熱容器１００の内袋１０３の内部に、冷凍食品などを収納し、蓋部１０４を外袋１０１に被せて、蓋部１０４の面ファスナ１０６，１０８を外袋１０１の面ファスナ１０７，１０９に各々係合させて閉じられ保存が行われる。   Frozen food or the like is stored inside the inner bag 103 of the assembled heat insulating container 100, the cover 104 is covered with the outer bag 101, and the surface fasteners 106, 108 of the cover 104 are connected to the surface fastener 107 of the outer bag 101, It is closed by being engaged with each of 109 and stored.

また、特許文献１に開示された断熱容器１００は、不使用時に折り畳み可能である。則ち、不使用時は、組み立て時とは逆に、外袋１０１から内袋１０３および５枚の断熱パネル１０２を取り外し、外袋１０１の内部に取り外した断熱パネル１０２および折り畳んだ内袋１０３を収納する。そして、外袋１０１を折り畳みつつ蓋部１０４を底面に対向させて重ね合わせ、ベルト１０５の両端にベルト１１３をかけて折り畳まれる。
特開２００３―１１２７８６号公報 Moreover, the heat insulation container 100 disclosed in Patent Document 1 can be folded when not in use. That is, when not in use, contrary to the assembly, the inner bag 103 and the five heat insulation panels 102 are removed from the outer bag 101, and the heat insulation panel 102 and the folded inner bag 103 are removed inside the outer bag 101. Store. Then, the outer bag 101 is folded while being overlapped with the lid portion 104 facing the bottom surface, and the belt 105 is folded over both ends of the belt 105.

A flexible engagement flap having a fastener is provided in a state of being biased upward from the lateral direction, and a hook-and-loop fastener is provided on the lid of the two surfaces corresponding to the hook-and-loop fastener. When the lid portions of the two surfaces are rotated toward the closed position, the lid portions are brought into contact with each other while pressing the engagement flap, and the surface fasteners are engaged with each other. Since the engagement flap is provided along the upper edge of the portion, when the lid portion is turned toward the closed posture, the engagement flap is pushed down by the inner surface of the lid portion so as to fall inward. Then, the surface fasteners of the engagement flap and the lid portion are engaged with each other, and the space between the bendable peripheral wall portion and the lid portion is shielded by the engagement flap. improves.

更には、係合フラップが横方向よりも上方へ向けて付勢されている。従って、係合フラップの付勢力に抗して蓋部を閉姿勢へ向けて回動させるだけで、自ずと係合フラップと蓋部の面ファスナ同士を係合させることができる。   Further, the engagement flap is urged upward from the lateral direction. Therefore, it is possible to naturally engage the engagement flap and the surface fasteners of the lid portion only by rotating the lid portion toward the closed posture against the urging force of the engagement flap.

更には、係合フラップを横方向よりも上方へ向けて付勢させる構成としては、例えば、係合フラップに復元力を有する素材（生地）を使用し、前記係合フラップを折曲可能な周壁部の上側縁のシート材に略上方へ向けて縫製するような構成を採ることができる。この構成によれば、長期間の使用によっても係合フラップが下方へ垂れ下がることがなく、蓋部を閉姿勢へ向けて回動させるだけで面ファスナ同士を確実に係合させることが可能となる。   Furthermore, as a configuration for urging the engagement flap upward from the lateral direction, for example, a material (cloth) having a restoring force is used for the engagement flap, and the engagement flap can be bent.

Refrigerated food can be delivered for more than 8 hours. Along with this, an extra refrigeration vehicle or refrigeration vehicle is not required for delivery, and the delivery cost can be reduced.

また、断熱容器に収納した冷凍食品の品質（温度）を維持しつつ配送可能な時間は、冷凍食品の収納割合や配送車の種類によって異なる。則ち、断熱容器に収納する冷凍食品の量、および、冷凍車または冷蔵車または常温車のいずれを使用するかによって、断熱容器に収納した冷凍食品の品質を保持しつつ配送可能な時間は異なる。   In addition, the delivery time while maintaining the quality (temperature) of the frozen food stored in the heat insulating container varies depending on the storage ratio of the frozen food and the type of delivery vehicle. In other words, the time that can be delivered while maintaining the quality of the frozen food stored in the insulated container varies depending on the amount of frozen food stored in the insulated container and whether the frozen car, refrigerated car, or normal temperature car is used. .

従って、配送する車種毎に予め試験を行い、冷凍食品の収納割合に対して冷凍食品の品質を維持しつつ配送可能な時間を求めておくことにより、配送に要する時間に応じて配送車両を容易に選択することができ、冷凍食品の品質を損なうこともない。   Therefore, it is easy to make the delivery vehicle according to the time required for delivery by conducting a test in advance for each vehicle type to be delivered and obtaining the delivery time while maintaining the quality of the frozen food with respect to the storage ratio of the frozen food. The quality of frozen foods is not impaired.

また、近時、冷凍車や冷蔵車のなかには、自動アイドリングストップを採用したものがある。また、ドライバーが自主的にアイドリングストップを励行する場合もある。自動アイドリングストップ車は、例えば、車両が停止しトランスミッションがニュートラル位置になると自動的にエンジンが停止し、発進に際してクラッチを踏むとエンジンが自動的にスタートする構造を備えた車両である。   Recently, some freezer and refrigerated vehicles employ an automatic idling stop. In addition, the driver may voluntarily encourage idling stop. The automatic idling stop vehicle is, for example, a vehicle having a structure in which the engine is automatically stopped when the vehicle is stopped and the transmission is in the neutral position, and the engine is automatically started when the clutch is stepped on the start.

ところが、このようなアイドリングストップを採用した冷凍車や冷蔵車では、エンジンの停止に伴って冷凍装置の駆動が停止する。このため、冷凍庫や冷蔵庫内部の温度が変動し易く、断熱性能の低い断熱容器に収納して配送する場合は、冷凍車であるにも拘わらず、アイドリングストップを採用しているがために冷凍食品の品質を損なうおそれがある。   However, in refrigeration vehicles and refrigeration vehicles that employ such an idling stop, the driving of the refrigeration system stops as the engine stops. For this reason, when the temperature inside the freezer or refrigerator is likely to fluctuate and is stored in a heat-insulated container with low heat insulation performance, the frozen food is used because it is an idling stop even though it is a freezer. The quality of the product may be impaired.

しかし、本発明によれば、断熱容器に真空断熱材を用い、内蓋により更に食品を包むことができるため、断熱性能が著しく高い。これにより、従来、断熱容器に収納した冷凍食品を冷凍車で配送するところを、冷凍車以外の車両で配送することを可能にしている。従って、アイドリングストップに伴う冷凍庫内部の温度変動によっても断熱容器内部の温度変動への影響が少なく、冷凍食品に影響を与えることが防止される。   However, according to the present invention, a vacuum heat insulating material is used for the heat insulating container, and the food can be further wrapped by the inner lid, so that the heat insulating performance is remarkably high. This makes it possible to deliver a frozen food stored in a heat-insulated container by a vehicle other than the frozen vehicle. Therefore, even if the temperature fluctuation inside the freezer accompanying the idling stop has little influence on the temperature fluctuation inside the heat insulating container, it is possible to prevent the frozen food from being affected.

ここで、冷凍車とは、断熱性能を持つ収納庫に専ら冷凍肉類やアイスクリームなどの冷凍食品の品質を維持しつつ搬送する車両で、収納庫内部温度を概ね−２５℃〜−１０℃の範囲で制御可能な冷凍装置を搭載した車両を指す。また、常温車とは、断熱性能を持たない通常の収納庫を備え、概ね１５℃〜２５℃の範囲で制御可能な装置を搭載した車両を指す。   Here, the freezer truck is a vehicle that conveys to a storage with heat insulation performance while maintaining the quality of frozen foods such as frozen meats and ice cream, and the internal temperature of the storage is about −25 ° C. to −10 ° C. A vehicle equipped with a refrigeration system that can be controlled within a range. Moreover, a normal temperature vehicle points out the vehicle which equips the normal storage which does not have heat insulation performance, and mounts the apparatus which can be controlled in the range of 15 to 25 degreeC in general.

以下、本発明の実施の形態について、図面を参照しながら説明するが、従来例または従来に説明した実施の形態と同一構成については同一符号を付して、その詳細な説明は省略する。なお、この実施の形態によってこの発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same reference numerals are given to the same configurations as those of the conventional examples or the embodiments described above, and detailed description thereof will be omitted.

また、真空断熱材の熱貫流率を０．１Ｗ／ｍ2Ｋより小さくするには、吸着剤を併用しなくてはならないため、コストが上昇する。逆に、熱貫流率を４．０Ｗ／ｍ2Ｋより大きくすると、冷凍車で運搬中、冷蔵食品の品質を維持することができなかった。以上より真空断熱材の熱貫流率は０．１Ｗ／ｍ2Ｋ以上、４．０Ｗ／ｍ2Ｋ以下とした。 Moreover, since it is necessary to use an adsorbent together in order to make the thermal conductivity of the vacuum heat insulating material smaller than 0.1 W / m 2 K, the cost increases. On the other hand, if the heat transmissibility is greater than 4.0 W / m 2 K, the quality of the refrigerated food could not be maintained during transportation with the freezer.

また、折り畳み時に、作業効率が要求されている場合には、内蓋２５を取り外すことにより作業効率を上昇させることもできる。また、断熱容器１の内部には、場合によっては蓄冷剤を収納する蓄冷剤収納部２６を設けている。蓄冷剤収納部２６は、図１、図５の様に、メッシュ状のネット材を用いて形成した袋体であり、図５の様に、内部に蓄冷剤３４を収納可能である。これにより、冷凍食品や冷蔵食品を保存する場合は、蓄冷剤３４および食品Ｓ１〜Ｓ４を内蓋２５で容易に覆うことができ、食品Ｓ１〜Ｓ４の断熱性能および遮蔽性の向上を図っている。   In addition, when work efficiency is required at the time of folding, the work efficiency can be increased by removing the inner lid 25. In addition, a cool storage agent storage unit 26 that stores a cool storage agent is provided inside the heat insulating container 1 in some cases. The regenerator storage unit 26 is a bag formed using a mesh net material as shown in FIGS. 1 and 5, and the regenerator 34 can be stored therein as shown in FIG. 5. Thereby, when preserve | saving frozen food or refrigerated food, the cool storage agent 34 and food S1-S4 can be easily covered with the inner cover 25, and the heat insulation performance and shielding of food S1-S4 are aimed at. .

次に、本実施の形態の断熱容器１の使用時に際しての組み立て手順を説明する。   Next, the assembly procedure when using the heat insulating container 1 of the present embodiment will be described.

まず、図６の様に、底面部２１を閉姿勢（水平方向）へ回動させて、図５の様に、側縁２９同士を突き合わせる。そして、一方の底面部２１に設けた係合フラップ２２を他方の底面部２１に押圧して、係合フラップ２２の面ファスナ２２ａと他方の底面部２１の面ファスナ２８を互いに係合させる。   First, as shown in FIG. 6, the bottom surface portion 21 is rotated to the closed posture (horizontal direction), and the side edges 29 are brought into contact with each other as shown in FIG. Then, the engagement flap 22 provided on one bottom surface portion 21 is pressed against the other bottom surface portion 21 so that the surface fastener 22a of the engagement flap 22 and the surface fastener 28 of the other bottom surface portion 21 are engaged with each other.

底面部２１をこのように係合すると、図５の様に、双方の底面部２１によって略平面が形成され、前記底面２１の下方には全面を覆うように底面シート２７が位置する。従って、底面部２１と周壁部１３との間に僅かな隙間が生じた場合でも、底面シート２７によって内外の連通が遮断され、断熱性能が損なわれることがない。   When the bottom surface portion 21 is engaged in this way, a substantially flat surface is formed by both the bottom surface portions 21 as shown in FIG. 5, and a bottom surface sheet 27 is positioned below the bottom surface 21 so as to cover the entire surface. Accordingly, even when a slight gap is generated between the bottom surface portion 21 and the peripheral wall portion 13, the communication between the inside and the outside is blocked by the bottom surface sheet 27, and the heat insulating performance is not impaired.

また、本実施の形態では、底面シート２７に耐水性および防水性を有するシート材３０ｂを用いており、内部に滞留する水が容器外部に流出することを防止している。   In the present embodiment, the bottom sheet 27 is made of a water-resistant and waterproof sheet material 30b to prevent water staying inside from flowing out of the container.

収納しようとする食品Ｓ１〜Ｓ４を全て収納すると、蓋部１６を閉姿勢（略水平方向）へ回動させる。図５の様に、蓋部１６を内方へ向けて回動すると、周壁部１３に略上方へ向けて設けられた係合フラップ２４が、蓋部１６の回動によって押圧されて内方へ倒れ、係合フラップ２４の面ファスナ２４ａと蓋部１６の面ファスナ１９が互いに係合する。そして、蓋部１６，１６の双方を閉姿勢に移動すると、係合フラップ２４の面ファスナ２４ａの全面が蓋部１６の面ファスナ１９と係合し、蓋部１６と周壁部１３との間が係合フラップ２４によって遮蔽される。   When all the foods S1 to S4 to be stored are stored, the lid 16 is rotated to the closed position (substantially horizontal direction). As shown in FIG. 5, when the lid portion 16 is rotated inward, the engagement flap 24 provided substantially upward on the peripheral wall portion 13 is pressed inward by the rotation of the lid portion 16. The surface fastener 24a of the engagement flap 24 and the surface fastener 19 of the lid portion 16 are engaged with each other. When both the lid portions 16 and 16 are moved to the closed posture, the entire surface fastener 24a of the engagement flap 24 is engaged with the surface fastener 19 of the lid portion 16, and the gap between the lid portion 16 and the peripheral wall portion 13 is established. It is shielded by the engagement flap 24.

また、蓋部１６を閉姿勢に移動すると、図５の様に、蓋部１６の側縁１７同士が互いに突き合わされる。そして、最後に、一方の蓋部１６に設けた係合フラップ１８を他方の蓋部１６に押圧して、面ファスナ１８ａ，２０を互いに係合させる。これにより、蓋部１６の側縁１７同士の突き合わせ部位が係合フラップ１８で覆われる。   When the lid portion 16 is moved to the closed posture, the side edges 17 of the lid portion 16 are abutted with each other as shown in FIG. Finally, the engagement flap 18 provided on one lid 16 is pressed against the other lid 16 to engage the surface fasteners 18a and 20 with each other. Thereby, the abutting portion between the side edges 17 of the lid portion 16 is covered with the engagement flap 18.

則ち、本実施の形態の断熱容器１は、底面部２１および蓋部１６を閉姿勢に回動して係合フラップ１８で係合するだけで、図７（ａ）の様に、真空断熱材３１を内包した周壁部１０，１３、底面部２１および蓋部１６で囲まれた箱体が形成される。   In other words, the heat insulating container 1 according to the present embodiment is simply vacuum insulated as shown in FIG. 7A only by rotating the bottom surface portion 21 and the lid portion 16 to the closed posture and engaging with the engaging flap 18. A box body surrounded by the peripheral wall portions 10 and 13 including the material 31, the bottom surface portion 21 and the lid portion 16 is formed.

そして、形成された箱体は、図５の様に、底面部２１の側縁２９同士の突き合わせ部位が係合フラップ２２で覆われると共に、底面部２１の外面が底面シート２７で覆われる。更に、図５の様に、蓋部１６の突き合わせ部位は係合フラップ１８で覆われると共に、蓋部１６と周壁部１３との間が係合フラップ２４によって遮蔽される。   As shown in FIG. 5, the formed box is covered with the engagement flap 22 at the abutting portion between the side edges 29 of the bottom surface portion 21, and the bottom surface 27 is covered with the outer surface of the bottom surface portion 21. Further, as shown in FIG. 5, the abutting portion of the lid portion 16 is covered with the engagement flap 18, and the gap between the lid portion 16 and the peripheral wall portion 13 is shielded by the engagement flap 24.

このように、本実施の形態の断熱容器１は、底面部２１および蓋部１６を閉姿勢に移動させて組み立てるだけで、内外の連通が完全に遮断され、しかも全面が真空断熱材で囲まれた極めて断熱性能の高い箱体を形成することができる。   As described above, the heat insulating container 1 of the present embodiment is assembled by moving the bottom surface portion 21 and the lid portion 16 to the closed posture, and the communication between the inside and the outside is completely blocked, and the entire surface is surrounded by the vacuum heat insulating material. In addition, a box body with extremely high heat insulation performance can be formed.

次に、不使用時に際しての断熱容器１の折り畳み手順を説明する。   Next, the folding procedure of the heat insulation container 1 when not in use will be described.

断熱容器１の折り畳みは、例えば、配送を終えて断熱容器１が空になった時や、配送元に戻って断熱容器１を収納保管する際に行われる。   The insulation container 1 is folded, for example, when the insulation container 1 is emptied after delivery, or when the insulation container 1 is stored and returned to the delivery source.

折り畳みに際しては、まず、図７（ａ）の様に、箱体とされている断熱容器１の蓋部１６の係合フラップ１８を掴んで引き上げる。そして、図７（ｂ）の様に、係合フラップ１８の面ファスナ１８ａと蓋部１６の面ファスナ２０の係合、および、係合フラップ２４の面ファスナ２４ａと蓋部１６の面ファスナ１９の係合を解除しつつ蓋部１６を開姿勢へ回動する。   When folding, first, as shown in FIG. 7A, the engaging flap 18 of the lid portion 16 of the heat insulating container 1 which is a box is grasped and pulled up. 7B, the engagement of the surface fastener 18a of the engagement flap 18 and the surface fastener 20 of the lid portion 16, and the engagement of the surface fastener 24a of the engagement flap 24 and the surface fastener 19 of the lid portion 16. The lid 16 is rotated to the open posture while releasing the engagement.

次いで、図６、図７（ｃ）の様に、内蓋２５を蓄冷剤収納部２６側へ寄せ、底面部２１の係合フラップ２２を掴んで引き上げて、係合フラップ２２の面ファスナ２２ａと底面部２１の面ファスナ２８の係合を解除する。そして、図７（ｄ）の様に、底面部２１を周壁部１０の内面に折り重ねると共に、蓋部１６を周壁部１０の外面に折り重ねる。   Next, as shown in FIG. 6 and FIG. 7C, the inner lid 25 is moved toward the regenerator storage unit 26, the engagement flap 22 of the bottom surface portion 21 is grasped and pulled up, and the surface fastener 22 a of the engagement flap 22 The engagement of the hook-and-loop fastener 28 of the bottom surface portion 21 is released. 7D, the bottom surface portion 21 is folded on the inner surface of the peripheral wall portion 10, and the lid portion 16 is folded on the outer surface of the peripheral wall portion 10.

続いて、図７（ｄ）の様に、周壁部１３を折り畳み線２３に沿って内方に折曲しつつ、周壁部１０同士を近接させる。これにより、図７（ｅ）の様に、外側から順に蓋部１６、周壁部１０、底面部２１および折曲された周壁部１３の４面が対象に重ね合わせられ、全８面が重なった状態で折り畳みが完了する。   Subsequently, as shown in FIG. 7D, the peripheral wall portions 10 are brought close to each other while the peripheral wall portion 13 is bent inward along the fold line 23. As a result, as shown in FIG. 7E, the four surfaces of the lid portion 16, the peripheral wall portion 10, the bottom surface portion 21, and the bent peripheral wall portion 13 are overlapped in order from the outside, and all eight surfaces overlap. Folding is completed in the state.

このように、本実施の形態の断熱容器１は、従来のように断熱パネルなどの部材の着脱を行うことなく、短時間に極めて容易にコンパクトに折り畳むことができる。   Thus, the heat insulation container 1 of this Embodiment can be folded up very easily in a short time, without attaching / detaching members, such as a heat insulation panel, conventionally.

断熱容器１を折り畳むと、図７（ｅ）の様に、蓋部１６、周壁部１０、底面部２１および周壁部１３の合計８面が折り重ねられた状態となる。   When the heat insulating container 1 is folded, as shown in FIG. 7E, a total of eight surfaces of the lid portion 16, the peripheral wall portion 10, the bottom surface portion 21, and the peripheral wall portion 13 are folded.

また、上記したように、本実施の形態では、周壁部１０，１３の高さＨ（３００ｍｍ）に対して、蓋部１６および底面部２１の長さＬ（２００ｍｍ）が短い。これにより、断熱容器１を折り畳むと、周壁部１０を最大外寸として前記８面が重ね合わせられた形状となる。   Further, as described above, in the present embodiment, the length L (200 mm) of the lid portion 16 and the bottom surface portion 21 is shorter than the height H (300 mm) of the peripheral wall portions 10 and 13. Thereby, when the heat insulation container 1 is folded, it will become the shape where the said 8 surface was piled up by making the surrounding wall part 10 into the largest outer dimension.

また、図１の断熱容器１は、使用時または不使用時に外部側に位置する全ての面に対して、図２で示した厚手のシート材３０ａを使用している。則ち、周壁部１０、周壁部１３および底面部２１の外面側と、蓋部１６の内面および外面側の各々の面に、図２で示した厚手のシート材３０ａを採用している。   Further, the heat insulating container 1 of FIG. 1 uses the thick sheet material 30a shown in FIG. 2 for all surfaces located on the outside side when in use or not in use. That is, the thick sheet material 30a shown in FIG. 2 is employed on the outer surface side of the peripheral wall portion 10, the peripheral wall portion 13, and the bottom surface portion 21, and on the inner surface and outer surface side of the lid portion 16, respectively.

より具体的には、蓋部１６は、真空断熱材３１の厚さ（１０ｍｍ）と、それを内包するシート材３０ａの厚さ（４ｍｍ＋４ｍｍ）の和である厚さ１８ｍｍである。周壁部１０，１３は、真空断熱材３１の厚さ（１０ｍｍ）と、それを内包するシート材３０ａ，３０ｂの厚さ（４ｍｍ＋２ｍｍ）の和である厚さ１６ｍｍである。また、底面部２１は、真空断熱材３１の厚さ（１０ｍｍ）と、それを内包するシート材３０ａ，３０ｂの厚さ（４ｍｍ＋２ｍｍ）の和である厚さ１６ｍｍである。従って、仮に面ファスナ２５aを下に折りながら、８面を折り畳んで重ね合わせると、その厚さの合計は略１３２ｍｍとなる。   More specifically, the lid portion 16 has a thickness of 18 mm, which is the sum of the thickness (10 mm) of the vacuum heat insulating material 31 and the thickness (4 mm + 4 mm) of the sheet material 30a that encloses it. The peripheral wall portions 10 and 13 have a thickness of 16 mm, which is the sum of the thickness (10 mm) of the vacuum heat insulating material 31 and the thicknesses (4 mm + 2 mm) of the sheet materials 30a and 30b enclosing it. Further, the bottom surface portion 21 has a thickness of 16 mm, which is the sum of the thickness (10 mm) of the vacuum heat insulating material 31 and the thicknesses (4 mm + 2 mm) of the sheet materials 30a and 30b enclosing it. Accordingly, if the eight fasteners are folded and overlapped while the surface fastener 25a is folded downward, the total thickness becomes approximately 132 mm.

則ち、本実施の形態の断熱容器１を折り畳むと、周壁部１０の外寸（Ｗ６００ｍｍ×Ｈ３００ｍｍ）を最大外寸とし、厚さを略１３２ｍｍに縮小することができ、使用時の箱体に比べて極めてコンパクトにすることができる。これにより、使用後の回収や保管を容易に行うことができる。   In other words, when the heat insulating container 1 of the present embodiment is folded, the outer dimension (W600 mm × H300 mm) of the peripheral wall portion 10 can be the maximum outer dimension, and the thickness can be reduced to approximately 132 mm. Compared to this, it can be made extremely compact. Thereby, collection | recovery and storage after use can be performed easily.

また、配送先に食品Ｓ１〜Ｓ４を収納した断熱容器１をそのまま引き渡す場合であっても、配送先では、断熱容器１の使用後はコンパクトに折り畳んで保管することができ、空の断熱容器１が無駄なスペースを占有することがない。特に、本実施の形態の断熱容器１は、組み立てや折り畳みを短時間に極めて容易に行うことができ、折り畳みが面倒なために使用が終了した断熱容器１を箱体のまま放置されて無駄なスペースを占有することが解消される。   Even if the insulated container 1 containing the foods S1 to S4 is delivered as it is to the delivery destination, the delivery destination can be compactly folded and stored after the use of the insulated container 1, and the empty insulated container 1 can be stored. Will not occupy wasted space. In particular, the heat insulating container 1 according to the present embodiment can be assembled and folded very easily in a short time, and the use of the heat insulating container 1 that has been discontinued due to troublesome folding is left as a box and is useless. Occupying space is eliminated.

また、断熱容器１をコンパクトに折り畳むことができるので、折り畳んだ複数の断熱容器１を汎用のロールパレットなどに収納して容易に移動させることも可能である。   Moreover, since the heat insulation container 1 can be folded compactly, it is also possible to store the plurality of folded heat insulation containers 1 in a general-purpose roll pallet or the like and easily move them.

また、上記したように、使用時または不使用時に外部側に位置する全ての面に対して、厚手のシート材３０ａを使用している。   Further, as described above, the thick sheet material 30a is used for all the surfaces positioned on the outside side when in use or not in use.

従って、使用に際して箱体が形成されたときは、各面に内包される真空断熱材３１が厚手のシート材３０ａによって外力から保護される。また、不使用時に折り畳むと、蓋部１６の内面が厚手のシート材３０ａによって外力から保護されることとなる。これにより、使用時および不使用時の双方において、真空断熱材３１を外力から保護することができ、真空断熱材３１の破損を防止して耐久性を向上することが可能となる。   Accordingly, when the box is formed in use, the vacuum heat insulating material 31 included in each surface is protected from external force by the thick sheet material 30a. When folded when not in use, the inner surface of the lid portion 16 is protected from external force by the thick sheet material 30a. Thereby, it is possible to protect the vacuum heat insulating material 31 from external force both at the time of use and at the time of non-use, prevent the vacuum heat insulating material 31 from being damaged, and improve the durability.

ここで、本実施の形態の断熱容器１は、上記したように、所定の強度および剛性を備えた真空断熱材３１を内包した蓋部１６、周壁部１０，１３および底面部２１で形成されるので、断熱容器１を単独で使用する場合でも、ある程度の強度および剛性を得ることができる。しかし、断熱容器１を、更に強度および剛性の高い保護容器に収納してセットで使用することにより、断熱容器１の耐久性を著しく向上させることができる。   Here, the heat insulation container 1 of this Embodiment is formed with the cover part 16, the surrounding wall parts 10 and 13, and the bottom face part 21 which included the vacuum heat insulating material 31 provided with predetermined intensity | strength and rigidity as mentioned above. Therefore, even when the heat insulating container 1 is used alone, a certain degree of strength and rigidity can be obtained. However, the durability of the heat insulating container 1 can be remarkably improved by storing the heat insulating container 1 in a protective container having higher strength and rigidity and using it as a set.

例えば、図８（ａ）の様に、断熱容器１をすっぽり収納可能な保護容器２を用意し、配送に際して箱体とされた断熱容器１を収納してセットで使用する構成を採ることができる。   For example, as shown in FIG. 8 (a), a protective container 2 that can completely store the heat insulating container 1 is prepared, and a structure in which the heat insulating container 1 that is a box is stored and used in a set can be taken. .

図８（ａ）に示す保護容器２は、合成樹脂材を成形加工して作製されたもので、上方が開放された箱形状を有し、極めて軽量である。保護容器２は、上部および下部の外面を全周に渡って突出させてフランジ部２ａ，２ｂを形成している。従って、フランジ部２ａを手掛かりとして保護容器２を容易に持ち運び可能である。また、断熱容器１を保護容器２に収納したまま、係合フラップ１８を掴んで蓋部１６を開閉することができる。   The protective container 2 shown in FIG. 8 (a) is produced by molding a synthetic resin material, has a box shape with the top opened, and is extremely lightweight. The protective container 2 is formed with flange portions 2a and 2b by projecting the outer surfaces of the upper and lower portions over the entire circumference. Therefore, the protective container 2 can be easily carried using the flange portion 2a as a clue. Further, the lid 16 can be opened and closed by grasping the engaging flap 18 while the heat insulating container 1 is stored in the protective container 2.

また、保護容器２のフランジ部２ｂを別の保護容器２のフランジ部２ａに重ね合わせて係合可能な構造とされており、保護容器２を多段に積み重ねることができる。従って、配送車などに、断熱容器１を収納した保護容器２を多数積み込む場合でも、多段に積み上げることによって積み込みスペースを有効に利用でき、しかも、断熱容器１に直接過大な荷重が加わることがなく損傷を受けることがない。   In addition, the flange portion 2b of the protective container 2 is overlapped with the flange portion 2a of another protective container 2 and can be engaged, and the protective containers 2 can be stacked in multiple stages. Therefore, even when a large number of protective containers 2 containing the heat insulating containers 1 are loaded into a delivery vehicle or the like, the loading space can be effectively used by stacking in multiple stages, and an excessive load is not directly applied to the heat insulating containers 1. There is no damage.

このように、断熱容器１を軽量化された保護容器２とセットで使用することにより、断熱容器１の耐久性を著しく向上させることが可能となる。   Thus, it becomes possible to improve the durability of the heat insulation container 1 remarkably by using the heat insulation container 1 with the protective container 2 reduced in weight.

更に、図７（ｅ）に示したように、断熱容器１は、周壁部１０を最大外寸として８面が重ね合わせられた形状に折り畳み可能である。従って、図８（ｂ），（ｃ）の様に、一つの保護容器２に、折り畳んだ複数の断熱容器１を収納することができる。   Furthermore, as shown in FIG.7 (e), the heat insulation container 1 can be folded in the shape where eight surfaces were piled up by making the surrounding wall part 10 into the largest outer dimension. Therefore, as shown in FIGS. 8B and 8C, a plurality of folded heat insulating containers 1 can be stored in one protective container 2.

これにより、複数の断熱容器１を纏めて保護容器２に収納して容易に持ち運ぶことができ、配送に際しての準備作業や回収作業を効率良く行うことができる。また、複数の断熱容器１を保護容器２に整理して保管でき、保管スペースも削減できる。   As a result, a plurality of heat insulating containers 1 can be stored together in the protective container 2 and easily carried, and preparation work and collection work for delivery can be performed efficiently. Further, a plurality of heat insulating containers 1 can be arranged and stored in the protective container 2, and the storage space can be reduced.

尚、図８で示した保護容器２は、箱形に形成されたものとして述べたが、保護容器２を折り畳み可能な構造とすることにより、準備や回収時における保護容器２の持ち運びが容易となり、保管スペースも削減することが可能となる。   Although the protective container 2 shown in FIG. 8 has been described as being formed in a box shape, the protective container 2 can be folded to facilitate carrying the protective container 2 during preparation and collection. The storage space can also be reduced.

以上のように、本発明にかかる断熱容器は断熱容器の断熱性能を極めて高くすることができ、冷凍食品、冷蔵食品、常温保存食品全般の保存が同時に可能となりため、多面的な用途に使用することができる。   As described above, the heat insulating container according to the present invention can greatly enhance the heat insulating performance of the heat insulating container, and can be used to store frozen foods, refrigerated foods, and foods stored at room temperature at the same time. be able to.
