Description
本発明は、断熱容器に関する。 The present invention relates to a heat insulating container.
従来より、青果物等の荷物を出荷拠点から目的地へと冷蔵輸送車で輸送することが行われている。冷蔵輸送車を使用した冷蔵輸送では、車内に積載される位置によって荷物の冷蔵温度にムラが生じることに加え、満載・混載や荷降ろしに起因して冷蔵効果が低減されてしまう。また、冷蔵輸送車を使用すると、途中で荷物の積替作業が発生したり、到着時等に荷物が常温のまま放置されたりする場合がある。このため、たとえ荷物を予冷したとしても目的地まで低温状態を維持することは困難であった。 2. Description of the Related Art Conventionally, cargo such as fruits and vegetables has been transported from a shipping base to a destination using refrigerated transport vehicles. In refrigerated transportation using refrigerated transport vehicles, the refrigeration temperature of the cargo varies depending on the position in the vehicle, and the refrigeration effect is reduced due to full loading, mixed loading, and unloading. Furthermore, when a refrigerated transport vehicle is used, cargo may have to be transshipped on the way, or the cargo may be left at room temperature upon arrival. For this reason, even if the cargo is pre-cooled, it is difficult to maintain it at a low temperature until the destination.
そこで、現在においては、荷物を収納するための断熱容器に、ドライアイスや蓄冷材等の冷媒を収納する冷媒収納空間を設け、冷媒収納空間に収納した冷媒から荷物へと冷気を供給する技術が提案されている（例えば、特許文献１及び２参照）。かかる技術を採用すると、冷媒から供給される冷気により荷物の低温を維持することができる、とされている。また、近年においては、荷物輸送後における容器の占有空間を縮小する目的で、分解・組立可能な断熱容器が種々提案されている（例えば、特許文献３参照）。 Therefore, there is currently a technology that provides a refrigerant storage space for storing refrigerant such as dry ice or cold storage material in an insulated container for storing luggage, and supplies cold air from the refrigerant stored in the refrigerant storage space to the luggage. It has been proposed (for example, see Patent Documents 1 and 2). It is said that by adopting this technology, it is possible to maintain the low temperature of the cargo using the cold air supplied from the refrigerant. Furthermore, in recent years, various heat-insulating containers that can be disassembled and assembled have been proposed for the purpose of reducing the space occupied by the container after cargo transportation (for example, see Patent Document 3).
ところで、冷蔵輸送車を使用した冷蔵輸送では、予冷庫にて荷物に予冷用の風を供給して通風予冷を行うのが一般的であるが、特許文献１及び２に記載されたような断熱容器は側板が底板と一体的に構成されていることから、当該断熱容器内に荷物を収納した状態で通風予冷を行うと、予冷用の風が側板によって遮られて冷却効率が低下するという問題がある。一方、特許文献３に記載の断熱容器は側板が床板から分離可能とされているが、側板が無い状態で床板上に荷物を積載すると荷物の位置ずれが生じてしまい、積載作業が滞ってしまうという問題が生じ得る。 By the way, in refrigerated transportation using a refrigerated transport vehicle, it is common to perform ventilation precooling by supplying precooling air to the cargo in a precooling warehouse, but the heat insulation method described in Patent Documents 1 and 2 Since the side plate of the container is integrated with the bottom plate, if ventilation pre-cooling is performed with cargo stored in the insulated container, the pre-cooling air will be blocked by the side plate, reducing cooling efficiency. There is. On the other hand, in the heat-insulating container described in Patent Document 3, the side plates are said to be separable from the floor plate, but if cargo is loaded on the floor plate without the side plates, the cargo will be misaligned and the loading operation will be delayed. This problem may arise.
本発明は、かかる事情に鑑みてなされたものであり、積載時における荷物の位置ずれを抑制して積載作業の効率化をもたらすことができ、かつ、通風予冷の冷却効率を向上させることができる断熱容器を提供することを目的とする。 The present invention has been made in view of the above circumstances, and can improve the efficiency of loading work by suppressing the displacement of cargo during loading, and can improve the cooling efficiency of ventilation pre-cooling. The purpose is to provide an insulated container.
前記目的を達成するため、本発明に係る断熱容器は、断熱材パネルからなる前板、後板、左右一対の側板、底板及び天板を備える略直方体状の断熱容器であって、剛性を有する材料で構成された平板状の第一支持部と、剛性を有する材料で構成された平板状の第二支持部と、からなる断面略Ｌ字状の支持部材を備え、支持部材の第一支持部は、底板の少なくとも一部を兼ねるものであるか、又は、底板に略平行に重ねられて配置されるものであり、支持部材の第二支持部は、後板の少なくとも一部を兼ねるものであるか、又は、後板の近傍に配置されるものである。 In order to achieve the above object, the insulating container according to the present invention is a generally rectangular parallelepiped-shaped insulating container comprising a front plate, a rear plate, a pair of left and right side plates, a bottom plate, and a top plate made of a heat insulating panel, and has rigidity. The support member has a substantially L-shaped cross section and includes a first support part in the form of a flat plate made of a material and a second support part in the form of a flat plate made of a rigid material. The second supporting part of the support member also serves as at least a part of the rear plate, or is arranged substantially parallel to the bottom plate, and the second support part of the support member also serves as at least a part of the rear plate. or placed near the rear plate.
かかる構成を採用すると、断面略Ｌ字状の支持部材の第一支持部を、底板の少なくとも一部として、又は、底板に略平行に重ねて配置（例えば略水平に配置）して、積載される荷物を支持することができる。この際、第一支持部から略垂直に立ち上がる第二支持部をガイドとして（すなわち第二支持部に荷物の縁部を当接させながら）荷物を積載することができる。従って、積載時における荷物の位置ずれを抑制することができるので、積載作業の効率化をもたらすことができる。また、断面略Ｌ字状の支持部材に荷物を載せたまま予冷庫で通風予冷を行うことができる。この際、他の側面を断熱材パネルで覆う必要がないため、予冷用の風が遮られることがなく、冷却効率を向上させることができる。さらに、荷物をフォークリフト等で移動させる際に断面略Ｌ字状の支持部材で荷物を支持することができるので、荷崩れを防止することができ、安全性の向上に寄与することができるとともに、フォークリフトのフォークを支持部材で受けることができるため、荷物や容器の破損を防ぐことができる。 When such a configuration is adopted, the first support part of the support member having a substantially L-shaped cross section is placed as at least a part of the bottom plate or is placed substantially parallel to the bottom plate (for example, placed substantially horizontally), and the first support part is stacked. can support loads. At this time, the cargo can be loaded using the second support section that stands up substantially perpendicularly from the first support section as a guide (that is, while the edge of the cargo is in contact with the second support section). Therefore, it is possible to suppress the positional shift of the cargo during loading, so that it is possible to improve the efficiency of the loading operation. In addition, ventilation precooling can be performed in the precooling warehouse while the cargo is placed on the support member having a substantially L-shaped cross section. At this time, since there is no need to cover the other sides with a heat insulating panel, the pre-cooling air is not blocked, and cooling efficiency can be improved. Furthermore, when the load is moved by a forklift or the like, the load can be supported by the support member having a substantially L-shaped cross section, which prevents the load from collapsing and contributes to improved safety. Since the fork of the forklift can be supported by the support member, damage to cargo and containers can be prevented.
本発明に係る断熱容器において、第一支持部及び第二支持部は、７００Ｎ／ｍｍ以上の曲げ剛性を有することができる。 In the heat insulating container according to the present invention, the first support part and the second support part can have a bending rigidity of 700 N/mm or more.
かかる構成を採用すると、支持部材を構成する第一支持部及び第二支持部の曲げ剛性を特定の値（７００Ｎ／ｍｍ以上）に設定するため、積載時における支持部材の変形や破損を抑制することができ、断熱容器が破損して容器内部の熱やガスが漏れることを抑制することができる。 When such a configuration is adopted, the bending rigidity of the first support part and the second support part constituting the support member is set to a specific value (700 N/mm or more), thereby suppressing deformation and damage of the support member during loading. This makes it possible to prevent the heat and gas inside the container from leaking due to breakage of the insulating container.

In such a case, the front plate, side plate, and top plate can be stacked on the bottom plate to form a laminate, either in a mutually separated state or in a connected state. In this case, the second support part of the support member can be arranged near the rear plate and can be configured to rise vertically upward to approximately the same height as the height of the laminate arranged on the bottom plate.
かかる構成を採用すると、支持部材の第二支持部を、後板の近傍に配置するとともに、第一支持部（底板）の上に積層された積層体（前板、側板、天板）の高さと略同じ高さまで鉛直上方に立ち上がるように構成することができる。従って、断熱容器を分解し、前板、側板及び天板からなる積層体を第一支持部（底板）の上に配置して小容積化する際に、積層体の縁部を第二支持部に当接させながら配置することができる。この結果、積層体の位置ずれを抑制することができ、小容積化作業の効率化に寄与することができる。また、第二支持部の高さを、第一支持部（底板）の上に配置した積層体の高さに略一致させているため、積層体を構成する板の不足を目視で容易に認識することができる。従って、パーツの紛失防止に寄与することができる。 When such a configuration is adopted, the second support part of the support member is arranged near the rear plate, and the height of the laminate (front plate, side plate, top plate) stacked on the first support part (bottom plate) is increased. It can be configured to rise vertically upward to approximately the same height as the Therefore, when disassembling the heat insulating container and placing the laminate consisting of the front plate, side plate and top plate on the first support part (bottom plate) to reduce the volume, the edge of the laminate is placed on the second support part. It can be placed in contact with the As a result, it is possible to suppress misalignment of the laminate, contributing to increased efficiency in volume reduction work. In addition, since the height of the second support part is approximately the same as the height of the laminate placed on the first support part (bottom plate), it is easy to visually recognize the lack of plates that make up the laminate. can do. Therefore, it is possible to contribute to prevention of loss of parts.
本発明に係る断熱容器において、支持部材の第一支持部を、底板の上に略水平に配置することができる。かかる場合において、前板、側板及び天板は、相互に分離した状態又は連結された状態で、第一支持部の上に積層されて積層体を構成することができる。この際、支持部材の第二支持部を、後板の近傍に配置するとともに、第一支持部の上に配置された積層体の高さと略同じ高さまで鉛直上方に立ち上がるように構成することができる。 In the heat insulating container according to the present invention, the first support part of the support member can be arranged substantially horizontally on the bottom plate. In such a case, the front plate, side plate, and top plate can be stacked on the first support part in a mutually separated state or in a connected state to form a laminate. At this time, the second support part of the support member may be arranged near the rear plate and configured to rise vertically upward to approximately the same height as the height of the laminate placed on the first support part. can.

It can be configured to rise vertically upward to a maximum height. Therefore, when the heat insulating container is disassembled and the laminate consisting of the front plate, side plate and top plate is placed on the first support part to reduce the volume, the edge of the laminate is brought into contact with the second support part. It can be placed while As a result, it is possible to suppress misalignment of the laminate, contributing to increased efficiency in volume reduction work. In addition, since the height of the second support section is approximately the same as the height of the laminate placed above the first support section, it is easy to visually recognize the lack of plates constituting the laminate. can. Therefore, it is possible to contribute to prevention of loss of parts.

It is preferable to do so. By surrounding the cargo with a heat insulating material panel made of a heat insulating material having a specific thermal resistance, the heat insulating effect can be effectively maintained. Further, it is preferable to employ a heat insulating panel made of a heat insulating material having a bending strength of 0.15 N/mm 2 or more. In this way, by surrounding the cargo with a heat insulating panel made of a heat insulating material with a specific bending strength, it is possible to suppress the deformation of the heat insulating panel during transportation, as well as absorb vibrations and shocks to prevent crushing. This allows you to reliably protect your luggage and maintain the insulation effect effectively.
本実施形態に係る断熱容器１は、図１、図３、図４に示すように、容器に収納される荷物を積載する際のガイド等として機能する支持部材８０を備えている。支持部材８０は、剛性を有する材料で構成された平板状の第一支持部８１と、剛性を有する材料で構成された平板状の第二支持部８２と、が断面Ｌ字状に剛接合されて構成されている。本実施形態における支持部材８０の第一支持部８１は、図１及び図３に示すように、底板４０の上に略平行に（略水平に）重ねられて配置された状態で、底板４０に固定されている。支持部材８０の第二支持部８２は、図１に示すように、後板２０の第一後板部２１の近傍に配置されており、図４に示すように、第一支持部８１の上に配置された（全てパーツが揃っている場合の）積層体Ｐの高さと略同じ高さまで鉛直上方に立ち上がるように構成されている。 As shown in FIGS. 1, 3, and 4, the heat insulating container 1 according to this embodiment includes a support member 80 that functions as a guide when loading cargo to be stored in the container. The support member 80 has a flat first support part 81 made of a rigid material and a flat second support part 82 made of a rigid material, which are rigidly joined to have an L-shaped cross section. It is composed of As shown in FIGS. 1 and 3, the first support part 81 of the support member 80 in this embodiment is placed on the bottom plate 40 in a state where it is stacked substantially parallel (substantially horizontally) on the bottom plate 40. Fixed. As shown in FIG. 1, the second support part 82 of the support member 80 is arranged near the first rear plate part 21 of the rear plate 20, and as shown in FIG. It is configured to rise vertically upward to approximately the same height as the height of the stacked body P (when all parts are arranged).
支持部材８０の第一支持部８１及び第二支持部８２は、７００Ｎ／ｍｍ以上の曲げ剛性を有している。このように第一支持部８１及び第二支持部８２の曲げ剛性を特定の値（７００Ｎ／ｍｍ以上）に設定するため、積載時における支持部材８０の変形や破損を抑制することができ、断熱容器１が破損して容器内部の熱やガスが漏れることを抑制することができる。第一支持部８１及び第二支持部８２の曲げ剛性は、２５００Ｎ／ｍｍ以上であることが好ましい。支持部材８０の材料は、上記曲げ強度を実現させるものであればよく、例えば金属材料、木材、プラスチック、石、ゴム等を採用することができる。支持部材８０は、多孔質構造を有してもよい。 The first support part 81 and the second support part 82 of the support member 80 have a bending rigidity of 700 N/mm or more. In this way, since the bending rigidity of the first support part 81 and the second support part 82 is set to a specific value (700 N/mm or more), deformation and damage of the support member 80 during loading can be suppressed, and the insulation It is possible to suppress leakage of heat and gas inside the container due to damage to the container 1. It is preferable that the bending rigidity of the first support part 81 and the second support part 82 is 2500 N/mm or more. The material of the support member 80 may be any material as long as it achieves the above-mentioned bending strength, and for example, metal materials, wood, plastics, stone, rubber, etc. can be used. Support member 80 may have a porous structure.
なお、断熱容器１は、ガス交換速度１回／時以下の気密性を有することが好ましい。このように特定の気密性を有する断熱容器１で荷物を包囲することにより、容器内のガス濃度（例えばＣＯ2濃度）を制御することができる。従って、例えば荷物が青果物である場合には、青果物の呼吸を抑制して鮮度を維持することができる。 In addition, it is preferable that the heat insulating container 1 has airtightness with a gas exchange rate of 1 time/hour or less. By surrounding the cargo with the heat-insulating container 1 having a specific airtightness in this manner, the gas concentration (for example, CO 2 concentration) within the container can be controlled. Therefore, for example, when the cargo is fruits and vegetables, the freshness of the fruits and vegetables can be maintained by suppressing the respiration of the fruits and vegetables.
