Description

本発明は、断熱容器に関する。 The present invention relates to a heat insulating container.

従来、発泡スチロール等の断熱材を用いた定温保管用の断熱容器が知られている。近年、凍結細胞等を保管または輸送する場合、前記断熱容器は、極低温領域での温度維持が要求される。このような凍結細胞等の定温保管用の断熱容器に発泡スチロール等の断熱材を用いた場合、発泡スチロール等の断熱性能では、断熱材の厚さが大きくなる、大量の蓄熱材を使用する必要があるといった問題がある。この結果、断熱容器の重量が大きくなる。 Conventionally, a heat insulating container for constant temperature storage using a heat insulating material such as Styrofoam is known. In recent years, when storing or transporting frozen cells and the like, the heat insulating container is required to maintain the temperature in a cryogenic region. When a heat insulating material such as Styrofoam is used for a heat insulating container for constant temperature storage of frozen cells or the like, it is necessary to use a large amount of heat storage material which increases the thickness of the heat insulating material in terms of heat insulating performance such as Styrofoam. There is a problem such as. As a result, the weight of the heat insulating container increases.

そこで、凍結細胞等の保管・輸送においては、断熱性能に優れた断熱容器が要求されている。なかでも、真空断熱材は、厚み方向の熱伝導率が極めて低い。それゆえ、真空断熱パネルを使用した断熱容器が注目されている。 Therefore, in the storage and transportation of frozen cells and the like, a heat insulating container having excellent heat insulating performance is required. Among them, the vacuum heat insulating material has extremely low thermal conductivity in the thickness direction. Therefore, a heat insulating container using a vacuum heat insulating panel is attracting attention.

例えば特許文献１，２には、真空断熱パネルを使用した断熱容器が開示されている。 For example, Patent Documents 1 and 2 disclose a heat insulating container using a vacuum heat insulating panel.

特許文献１には、折り畳み式保冷保温容器が開示されている。そして、当該容器の壁部を構成する断熱体は、真空断熱パネルとしての第一断熱材と第二断熱材とがカバー材内に収容された構成となっている。 Patent Document 1 discloses a foldable cold insulation and heat insulation container. The heat insulating body constituting the wall portion of the container has a structure in which the first heat insulating material and the second heat insulating material as the vacuum heat insulating panel are housed in the cover material.

また、特許文献２に開示された断熱容器では、壁部を構成する断熱体が、真空断熱パネルとしての真空断熱要素と、前記真空断熱要素に組み合わされた断熱要素と、を備えている。そして、前記真空断熱要素および前記断熱要素は共に外皮によって覆われている。 Further, in the heat insulating container disclosed in Patent Document 2, the heat insulating body constituting the wall portion includes a vacuum heat insulating element as a vacuum heat insulating panel and a heat insulating element combined with the vacuum heat insulating element. Then, both the vacuum heat insulating element and the heat insulating element are covered with an exodermis.

上述の特許文献１または２に記載の断熱容器は、カバー材または外皮といったケース内に真空断熱パネルおよび他の断熱材の集合物が収容された構成となっている。当該集合物は、ケースと隙間なく収容されている。このため、特許文献１および２に記載の技術では、ケースから真空断熱パネルを取り外すことが困難であるという問題があることが本発明者らの検討により明らかとなった。 The heat insulating container described in Patent Document 1 or 2 described above has a structure in which a vacuum heat insulating panel and an aggregate of other heat insulating materials are housed in a case such as a cover material or an outer skin. The assembly is housed tightly with the case. Therefore, it has been clarified by the studies by the present inventors that the techniques described in Patent Documents 1 and 2 have a problem that it is difficult to remove the vacuum heat insulating panel from the case.

また、特許文献１および２に記載の断熱容器では、真空断熱パネルの損傷を防ぎ、かつ側壁同士の接合部分での熱の漏洩を防止する点で改善の余地がある。 Further, in the heat insulating container described in Patent Documents 1 and 2, there is room for improvement in preventing damage to the vacuum heat insulating panel and preventing heat leakage at the joint portion between the side walls.

本発明の一態様は、（ｉ）外部衝撃による真空断熱パネルの損傷を防ぎ、かつ側壁同士の接合部分での熱の漏洩を防止するとともに、（ｉｉ）側壁を構成する真空断熱側面パネルについて側面ケースから真空断熱パネルの出し入れが容易であり、出し入れ時に真空断熱パネルを損傷することを防ぐことができる断熱容器を実現することを目的とする。 One aspect of the present invention is to (i) prevent damage to the vacuum heat insulating panel due to an external impact, prevent heat leakage at the joint portion between the side walls, and (ii) side surface of the vacuum heat insulating side panel constituting the side wall. It is an object of the present invention to realize a heat insulating container in which the vacuum heat insulating panel can be easily taken in and out of the case and the vacuum heat insulating panel can be prevented from being damaged at the time of taking in and out.

上記の課題を解決するために、本発明の一態様に係る断熱容器は、上面板、下面板、複数の側面板、および前記上面板と、前記下面板と、前記側面板とにより形成された断熱空間を備え、前記複数の側面板はそれぞれ、真空断熱側面パネルと、前記真空断熱側面パネルを収容する側面ケースと、を備え、前記真空断熱側面パネルは、前記側面ケース内にて、前記断熱空間側の第１の側壁および当該第１の側壁に隣接する第２の側壁に接し、かつ前記第２の側壁と対向する第３の側壁と離間するように配置されており、前記複数の側面板はそれぞれ、一方の側面板の前記第１の側壁が他方の側面板の前記第２の側壁と接するように、配置されている構成である。 In order to solve the above problems, the heat insulating container according to one aspect of the present invention is formed of a top plate, a bottom plate, a plurality of side plates, the top plate, the bottom plate, and the side plates. A heat insulating space is provided, each of the plurality of side plates includes a vacuum heat insulating side panel and a side case accommodating the vacuum heat insulating side panel, and the vacuum heat insulating side panel comprises the heat insulating in the side case. It is arranged so as to be in contact with the first side wall on the space side and the second side wall adjacent to the first side wall, and away from the third side wall facing the second side wall, and the plurality of sides. Each of the face plates is arranged so that the first side wall of one side plate is in contact with the second side wall of the other side plate.

本発明の一態様によれば、（ｉ）外部衝撃による真空断熱パネルの損傷を防ぎ、かつ側壁同士の接合部分での熱の漏洩を防止するとともに、（ｉｉ）側壁を構成する真空断熱側面パネルについて側面ケースから真空断熱パネルの出し入れが容易であり、出し入れ時に真空断熱パネルを損傷することを防ぐことができるという効果を奏する。 According to one aspect of the present invention, (i) damage to the vacuum heat insulating panel due to an external impact is prevented, heat leakage at the joint portion between the side walls is prevented, and (ii) the vacuum heat insulating side panel constituting the side wall is prevented. The vacuum insulation panel can be easily taken in and out from the side case, and it is possible to prevent the vacuum insulation panel from being damaged when it is taken in and out.

〔実施形態１〕
以下、本発明の一実施形態について、詳細に説明する。図１は、本実施形態に係る定温保管容器１００（断熱容器）の概略構成を示す分解斜視図である。 [Embodiment 1]
Hereinafter, one embodiment of the present invention will be described in detail. FIG. 1 is an exploded perspective view showing a schematic configuration of a constant temperature storage container 100 (insulated container) according to the present embodiment.

図１に示されるように、本実施形態に係る定温保管容器１００は、断熱容器本体１０と、断熱容器本体１０を収容する外箱２０と、を備えている。外箱２０は、断熱容器本体１０が収容される外箱本体２０ａと、外箱本体２０ａを閉塞する蓋部２０ｂと、を備えている。外箱本体２０ａおよび蓋部２０ｂの材料は、特に限定されないが、ポリスチレン系樹脂発泡体、ポリオレフィン系樹脂発泡体などの発泡樹脂、プラスチック段ボール、紙製ダンボールなどの段ボールが好ましく、断熱性の観点からポリスチレン系樹脂発泡体、ポリオレフィン系樹脂発泡体などの発泡樹脂がより好ましい。また、外箱２０は、発泡樹脂と段ボールとを組み合わせて構成してもよい。さらに、外箱２０は、外装材を備えていてもよく、外装材は、例えば、繊維製シートの一方の面にアルミ蒸着されたアルミ蒸着シートで構成されている。外箱２０は、断熱容器本体１０を適合して収容する寸法に形成される。断熱容器本体１０は、外箱２０に収容される。 As shown in FIG. 1, the constant temperature storage container 100 according to the present embodiment includes a heat insulating container main body 10 and an outer box 20 for accommodating the heat insulating container main body 10. The outer box 20 includes an outer box main body 20a in which the heat insulating container main body 10 is housed, and a lid portion 20b that closes the outer box main body 20a. The material of the outer box body 20a and the lid 20b is not particularly limited, but foamed resins such as polystyrene-based resin foams and polyolefin-based resin foams, and corrugated cardboard such as plastic cardboard and paper cardboard are preferable, and from the viewpoint of heat insulating properties. Foamed resins such as polystyrene-based resin foams and polyolefin-based resin foams are more preferable. Further, the outer box 20 may be formed by combining foamed resin and corrugated cardboard. Further, the outer box 20 may be provided with an exterior material, and the exterior material is composed of, for example, an aluminum-deposited aluminum-deposited sheet on one surface of a fiber sheet. The outer box 20 is formed in a size that fits and accommodates the heat insulating container main body 10. The heat insulating container main body 10 is housed in the outer box 20.

断熱容器本体１０は、直方体の箱形状であり、側面を構成する側面板１〜４と、下面を構成する下面板５と、上面を構成する上面板６と、を備えている。側面板１〜４は、断熱容器本体１０の角部Ａ〜Ｄ（接合部分）にて、互いに端部が隣り合うように接合されている。断熱容器本体１０では、側面板１〜４、下面板５、および上面板６により、断熱空間Ｅが形成されている（図３参照）。なお、ここでは、断熱容器本体１０における下面板５側を下側とし、その反対側（すなわち、上面板６側）を上側とする。また、側面板１〜４各々について、下側から上側へ向かう方向を高さ方向とし、当該高さ方向および側面板の厚さ方向の両方に垂直な方向を幅方向とする。 The heat insulating container main body 10 has a rectangular parallelepiped box shape, and includes side plates 1 to 4 forming side surfaces, a lower surface plate 5 forming a lower surface, and an upper surface plate 6 forming an upper surface. The side plates 1 to 4 are joined at the corners A to D (joining portions) of the heat insulating container main body 10 so that their ends are adjacent to each other. In the heat insulating container main body 10, the heat insulating space E is formed by the side plates 1 to 4, the bottom plate 5, and the top plate 6 (see FIG. 3). Here, the lower surface plate 5 side of the heat insulating container main body 10 is the lower side, and the opposite side (that is, the upper surface plate 6 side) is the upper side. Further, for each of the side plates 1 to 4, the direction from the lower side to the upper side is the height direction, and the direction perpendicular to both the height direction and the thickness direction of the side plates is the width direction.

断熱容器本体１０では、側面板１〜４、下面板５、および上面板６は、真空断熱パネルを備えている。外部衝撃による真空断熱パネルの損傷を防ぐために、これらの真空断熱パネルは、保護ケースに収容されている。当該保護ケースは、真空断熱パネルの寸法に適合した寸法に設定されている。真空断熱パネルの寸法に適合した寸法とは、１つの真空断熱パネルが収容されることを想定して設計された保護ケースの寸法を意味する。当該寸法は、保護ケースの体積に対する真空断熱パネルの占有体積の割合が５０％以上１００％未満、好ましくは７０％以上９８以下、より好ましくは８０％以上９５％以下となる寸法である。また、前記保護ケースの材料は、真空断熱パネルの保護に使用される従来公知の材料であればよく、例えば、ポリエチレンテレフタレート（ＰＥＴ）、ポリ塩化ビニル、ポリカーボネート、ポリエチレン、ポリプロピレン等が挙げられる。なお、断熱容器本体１０においては、側面板１〜４、下面板５、および上面板６のうち少なくとも隣り合う２つのパネルが真空断熱パネルを備えていればよい。 In the heat insulating container main body 10, the side plates 1 to 4, the bottom plate 5, and the top plate 6 are provided with a vacuum heat insulating panel. These vacuum insulation panels are housed in a protective case to prevent damage to the vacuum insulation panels due to external impact. The protective case is set to a size suitable for the size of the vacuum insulation panel. The dimensions conforming to the dimensions of the vacuum insulation panel mean the dimensions of the protective case designed to accommodate one vacuum insulation panel. The dimensions are such that the ratio of the occupied volume of the vacuum insulation panel to the volume of the protective case is 50% or more and less than 100%, preferably 70% or more and 98 or less, and more preferably 80% or more and 95% or less. Further, the material of the protective case may be any conventionally known material used for protecting the vacuum heat insulating panel, and examples thereof include polyethylene terephthalate (PET), polyvinyl chloride, polycarbonate, polyethylene and polypropylene. In the heat insulating container main body 10, at least two adjacent panels of the side plates 1 to 4, the bottom plate 5, and the top plate 6 may be provided with the vacuum heat insulating panel.

図２は、本実施形態に係る定温保管容器１００に備えられた断熱容器本体１０の前提的構成を概略的に示す水平断面図である。図２に示されるように、前提的構成としての断熱容器本体１０’では、側面板１〜４はそれぞれ、真空断熱側面パネル１１、２１、３１、および４１と、側面ケース１２、２２、３２および４２と、を備えている。なお、以下、真空断熱側面パネル１１、２１、３１、および４１は、真空断熱側面パネル１１〜４１と称することもある。また、側面ケース１２、２２、３２および４２は、側面ケース１２〜４２と称することもある。 FIG. 2 is a horizontal cross-sectional view schematically showing a prerequisite configuration of a heat insulating container main body 10 provided in the constant temperature storage container 100 according to the present embodiment. As shown in FIG. 2, in the heat insulating container main body 10'as a prerequisite configuration, the side plates 1 to 4 are the vacuum heat insulating side panels 11, 21, 31, and 41, and the side cases 12, 22, 32, respectively. 42 and. Hereinafter, the vacuum insulation side panels 11, 21, 31, and 41 may be referred to as vacuum insulation side panels 11 to 41. The side cases 12, 22, 32 and 42 may also be referred to as side cases 12 to 42.

側面ケース１２〜４２はそれぞれ、真空断熱側面パネル１１〜４１を収容するためのケースであり、前記保護ケースに対応する。側面ケース１２〜４２はそれぞれ、真空断熱側面パネル１１〜４１の寸法に適合した寸法で設計されている。 The side cases 12 to 42 are cases for accommodating the vacuum heat insulating side panels 11 to 41, respectively, and correspond to the protective case. The side cases 12 to 42 are each designed to have dimensions conforming to the dimensions of the vacuum insulated side panels 11 to 41.

ここで、図２に示されるように、通常、真空断熱側面パネル１１〜４１はそれぞれ、側面ケース１２〜４２の中心に配置される。このため、断熱容器本体１０の角部Ａ〜Ｄにおいて、真空断熱側面パネル１１〜４１同士の間に隙間が生じる。通常、真空断熱側面パネルは、各パネルで寸法のバラツキが大きい。このため、角部Ａ〜Ｄにおける真空断熱側面パネル１１〜４１同士の隙間にもバラツキが生じる。さらに、側面ケース１２〜４２の寸法は、真空断熱側面パネルの寸法のバラツキ範囲の中で最大寸法に適合して設計される。このため、角部Ａ〜Ｄにおける真空断熱側面パネル１１〜４１同士の隙間が大きくなる。 Here, as shown in FIG. 2, the vacuum insulation side panels 11 to 41 are usually arranged at the center of the side cases 12 to 42, respectively. Therefore, in the corners A to D of the heat insulating container main body 10, a gap is generated between the vacuum heat insulating side panels 11 to 41. Usually, the vacuum insulation side panel has a large variation in dimensions among the panels. Therefore, the gaps between the vacuum heat insulating side panels 11 to 41 at the corners A to D also vary. Further, the dimensions of the side cases 12 to 42 are designed to fit the maximum dimension within the dimensional variation range of the vacuum insulated side panel. Therefore, the gap between the vacuum heat insulating side panels 11 to 41 at the corners A to D becomes large.

このように真空断熱側面パネル１１〜４１同士に隙間が生じるため、断熱容器本体１０’では、側面板１〜４の接合部分（角部Ａ〜Ｄ）にて熱の漏洩が生じる。 Since a gap is formed between the vacuum heat insulating side panels 11 to 41 in this way, heat leaks at the joint portions (corners A to D) of the side plates 1 to 4 in the heat insulating container main body 10'.

また、このような熱の漏洩を防止するために、真空断熱側面パネル１１〜４１それぞれが側面ケース１２〜４２に隙間なく収容されるように側面ケース１２〜４２の寸法を設定することが考えられる。しかし、この場合、側面ケース１２〜４２それぞれから真空断熱側面パネル１１〜４１を出し入れすることが困難である。さらには、出し入れする時に、真空断熱側面パネル１１〜４１が損傷するおそれがある。 Further, in order to prevent such heat leakage, it is conceivable to set the dimensions of the side case 12 to 42 so that each of the vacuum heat insulating side panels 11 to 41 is housed in the side cases 12 to 42 without a gap. .. However, in this case, it is difficult to put in and take out the vacuum heat insulating side panels 11 to 41 from each of the side cases 12 to 42. Furthermore, the vacuum insulation side panels 11 to 41 may be damaged when they are taken in and out.

本実施形態に係る定温保管容器１００は、次の（１）および（２）の両方の効果を奏する。（１）側面ケース１２〜４２により真空断熱側面パネル１１〜１４の損傷を防ぎ、かつ側面板１〜４同士の接合部分での熱の漏洩を防止する。（２）側面板１〜４について側面ケース１２〜４２それぞれから真空断熱側面パネル１１〜４１の出し入れが容易になる。図３は、本実施形態に係る定温保管容器１００に備えられた断熱容器本体１０の概略構成を示す水平断面図である。 The constant temperature storage container 100 according to the present embodiment exhibits both the following effects (1) and (2). (1) The side cases 12 to 42 prevent damage to the vacuum heat insulating side panels 11 to 14, and prevent heat leakage at the joint portion between the side plates 1 to 4. (2) With respect to the side plates 1 to 4, the vacuum heat insulating side panels 11 to 41 can be easily taken in and out from each of the side cases 12 to 42. FIG. 3 is a horizontal cross-sectional view showing a schematic configuration of a heat insulating container main body 10 provided in the constant temperature storage container 100 according to the present embodiment.

図３に示されるように、断熱容器本体１０の側面板１〜４において、真空断熱側面パネル１１〜４１は、側面ケース１２〜４２内にて、次の（ａ）および（ｂ）の両方の要件を満たすように配置されている。（ａ）真空断熱側面パネル１１〜４１はそれぞれ、断熱空間Ｅ側の第１側壁１２ａ〜４２ａおよび第１側壁１２ａ〜４２ａに隣接する第２側壁１２ｂ〜４２ｂに接する。（ｂ）真空断熱側面パネル１１〜４１はそれぞれ、第２側壁１２ｂ〜４２ｂと対向する第３側壁１２ｃ〜４２ｃと離間する。なお、第１側壁１２ａ〜４２ａは、第１側壁１２ａ、２２ａ、３２ａおよび４２ａを意図する。また、第２側壁１２ｂ〜４２ｂは、第２側壁１２ｂ、２２ｂ、３２ｂ、および４２ｂを意図する。 As shown in FIG. 3, in the side plates 1 to 4 of the heat insulating container main body 10, the vacuum heat insulating side panels 11 to 41 are placed in the side cases 12 to 42 in both of the following (a) and (b). Arranged to meet the requirements. (A) The vacuum heat insulating side panels 11 to 41 are in contact with the first side walls 12a to 42a on the heat insulating space E side and the second side walls 12b to 42b adjacent to the first side walls 12a to 42a, respectively. (B) The vacuum heat insulating side panels 11 to 41 are separated from the third side walls 12c to 42c facing the second side walls 12b to 42b, respectively. The first side walls 12a to 42a are intended as the first side walls 12a, 22a, 32a and 42a. The second side walls 12b to 42b are intended as the second side walls 12b, 22b, 32b, and 42b.

ここで、前記（ａ）の要件において、真空断熱側面パネル１１〜４１が第１側壁１２ａ〜４２ａまたは第２側壁１２ｂ〜４２ｂに接する構成は、接する状態について、特に限定されない。例えば、当該構成は、真空断熱側面パネル１１〜４１の面全体に隙間なく第１側壁１２ａ〜４２ａまたは第２側壁１２ｂ〜４２ｂが密着した状態であってもよい。また、当該構成は、弾性接着剤等により真空断熱側面パネル１１〜４１と第１側壁１２ａ〜４２ａまたは第２側壁１２ｂ〜４２ｂとが接着した状態であってもよい。さらに、当該構成は、真空断熱側面パネル１１〜４１の凹凸面に第１側壁１２ａ〜４２ａまたは第２側壁１２ｂ〜４２ｂが接した状態であってもよい。一般的に、真空断熱パネルは、断熱材料からなる芯材と、芯材を収容する袋状の外包材（外装フィルム等）と、を備え、外包材の内部が真空状態に維持されている。外包材の形態等に応じて、真空断熱側面パネル１１〜４１の外面は、凹凸面または平面になり得る。 Here, in the requirement (a), the configuration in which the vacuum heat insulating side panels 11 to 41 are in contact with the first side walls 12a to 42a or the second side walls 12b to 42b is not particularly limited in terms of the state of contact. For example, in this configuration, the first side walls 12a to 42a or the second side walls 12b to 42b may be in close contact with each other on the entire surface of the vacuum heat insulating side panels 11 to 41 without any gap. Further, the configuration may be in a state where the vacuum heat insulating side panels 11 to 41 and the first side walls 12a to 42a or the second side walls 12b to 42b are adhered to each other by an elastic adhesive or the like. Further, the configuration may be such that the first side wall 12a to 42a or the second side wall 12b to 42b are in contact with the uneven surface of the vacuum heat insulating side panels 11 to 41. Generally, the vacuum heat insulating panel includes a core material made of a heat insulating material and a bag-shaped outer packaging material (exterior film or the like) for accommodating the core material, and the inside of the outer packaging material is maintained in a vacuum state. Depending on the form of the outer packaging material and the like, the outer surface of the vacuum heat insulating side panels 11 to 41 may be an uneven surface or a flat surface.

また、前記（ａ）および（ｂ）の両方の要件を満たすように配置された状態が維持されていれば、真空断熱側面パネル１１〜４１はそれぞれ、側面ケース１２〜４２に対して任意の公知の形態で配置され得る。例えば、真空断熱側面パネル１１〜４１はそれぞれ、弾性接着剤等の接着剤、または両面テープによって、側面ケース１２〜４２に対して配置されていてもよい。このような真空断熱側面パネル１１〜４１の側面ケース１２〜４２に対する配置形態は、定温保管容器１００の使用状況（運搬または移動の有無等）に応じて適宜設定し得る。 Further, as long as the state of being arranged so as to satisfy the requirements of both (a) and (b) is maintained, the vacuum heat insulating side panels 11 to 41 are arbitrarily known with respect to the side cases 12 to 42, respectively. Can be arranged in the form of. For example, the vacuum heat insulating side panels 11 to 41 may be arranged with respect to the side cases 12 to 42 by an adhesive such as an elastic adhesive or double-sided tape, respectively. The arrangement form of the vacuum heat insulating side panels 11 to 41 with respect to the side cases 12 to 42 can be appropriately set according to the usage situation (whether or not the container is transported or moved, etc.) of the constant temperature storage container 100.

さらに、断熱容器本体１０では、複数の側面板１〜４はそれぞれ、一方の側面板の第１側壁が他方の側面板の第２側壁と接するように、配置されている。より具体的には、図３に示されるように、側面板１〜４はそれぞれ、次の（ｃ）〜（ｆ）を満たすように配置されている。（ｃ）角部Ａにおいて、側面板１の第１側壁１２ａが側面板２の第２側壁２２ｂと接する。（ｄ）角部Ｂにおいて、側面板２の第１側壁２２ａが側面板３の第２側壁３２ｂに接する。（ｅ）角部Ｃにおいて、側面板３の第１側壁３２ａが側面板４の第２側壁４２ｂに接する。（ｆ）角部Ｄにおいて、側面板４の第１側壁４２ａが側面板１の第２側壁１２ｂに接する。 Further, in the heat insulating container main body 10, each of the plurality of side plates 1 to 4 is arranged so that the first side wall of one side plate is in contact with the second side wall of the other side plate. More specifically, as shown in FIG. 3, the side plates 1 to 4 are arranged so as to satisfy the following (c) to (f), respectively. (C) At the corner A, the first side wall 12a of the side plate 1 comes into contact with the second side wall 22b of the side plate 2. (D) At the corner portion B, the first side wall 22a of the side plate 2 comes into contact with the second side wall 32b of the side plate 3. (E) At the corner portion C, the first side wall 32a of the side plate 3 comes into contact with the second side wall 42b of the side plate 4. (F) At the corner D, the first side wall 42a of the side plate 4 comes into contact with the second side wall 12b of the side plate 1.

上述のように、断熱容器本体１０では、前記（ａ）および（ｂ）の要件を満たすように、真空断熱側面パネル１１〜４１が側面ケース１２〜４２内にて配置されているとともに、前記（ｃ）〜（ｆ）の要件を満たすように側面板１〜４が配置されている。それゆえ、断熱容器本体１０では、側面板１〜４の接合部分（角部Ａ〜Ｄ）それぞれにおいて、真空断熱側面パネル１１〜４１同士は隙間なく接することになる。このため、断熱容器本体１０では、（１）側面ケース１２〜４２により真空断熱側面パネル１１〜１４の損傷を防ぎ、かつ側面板１〜４同士の接合部分での熱の漏洩を防止できる。 As described above, in the heat insulating container main body 10, the vacuum heat insulating side panels 11 to 41 are arranged in the side cases 12 to 42 so as to satisfy the requirements (a) and (b), and the above ( c) Side plates 1 to 4 are arranged so as to satisfy the requirements of (f). Therefore, in the heat insulating container main body 10, the vacuum heat insulating side panels 11 to 41 are in contact with each other without a gap at each of the joint portions (corners A to D) of the side plates 1 to 4. Therefore, in the heat insulating container main body 10, (1) the side cases 12 to 42 can prevent damage to the vacuum heat insulating side panels 11 to 14, and prevent heat leakage at the joint portion between the side plates 1 to 4.

さらに、（ｂ）真空断熱側面パネル１１〜４１はそれぞれ、第２側壁１２ｂ〜４２ｂと対向する第３側壁１２ｃ〜４２ｃと離間する。この離間により、真空断熱側面パネル１１〜４１とこれら真空断熱側面パネルを収容する側面ケース１２〜４２との間に隙間が生じる。その結果、（２）側面板１〜４について側面ケース１２〜４２それぞれから真空断熱側面パネル１１〜４１の出し入れが容易になる。また、側面ケース１２〜４２それぞれから出し入れする時に、真空断熱側面パネル１１〜４１を損傷することを防ぐことができる。 Further, (b) the vacuum heat insulating side panels 11 to 41 are separated from the third side walls 12c to 42c facing the second side walls 12b to 42b, respectively. Due to this separation, a gap is created between the vacuum-insulated side panels 11 to 41 and the side cases 12 to 42 accommodating these vacuum-insulated side panels. As a result, (2) the vacuum heat insulating side panels 11 to 41 can be easily taken in and out from the side cases 12 to 42 for the side plates 1 to 4. Further, it is possible to prevent the vacuum heat insulating side panels 11 to 41 from being damaged when they are taken in and out from the side cases 12 to 42 respectively.

なお、本実施形態では、側面ケース１２〜４２にて、真空断熱側面パネル１１〜４１それぞれが少なくとも第３側壁１２ｃ〜４２ｃと離間していれば、前記（２）の効果を奏し得る。図３に示されるように、第３側壁１２ｃ〜４２ｃに加えて、真空断熱側面パネル１１〜４１はそれぞれ、第１側壁１２ａ〜４２ａと対向する第４側壁１２ｄ〜４２ｄと離間することが好ましい。すなわち、好ましくは、真空断熱側面パネル１１〜４１はそれぞれ、第１側壁１２ａ〜４２ａおよび第２側壁１２ｂ〜４２ｂ以外の全ての側壁（第３側壁１２ｃ〜４２ｃおよび第４側壁１２ｄ〜４２ｄ）と離間するように配置されている。なお、第４側壁１２ｄ〜４２ｄは、第４側壁１２ｄ、２２ｄ、３２ｄ、および４２ｄを意図する。上記の構成により、真空断熱側面パネル１１〜４１と側面ケース１２〜４２との間の隙間が大きくなる。それゆえ、側面板１〜４について側面ケース１２〜４２それぞれから真空断熱側面パネル１１〜４１の出し入れがより一層容易になる。 In the present embodiment, in the side cases 12 to 42, if each of the vacuum heat insulating side panels 11 to 41 is separated from at least the third side wall 12c to 42c, the effect of (2) can be obtained. As shown in FIG. 3, in addition to the third side walls 12c to 42c, the vacuum insulated side panels 11 to 41 are preferably separated from the fourth side walls 12d to 42d facing the first side walls 12a to 42a, respectively. That is, preferably, the vacuum-insulated side panels 11 to 41 are separated from all side walls (third side walls 12c to 42c and fourth side walls 12d to 42d) other than the first side walls 12a to 42a and the second side walls 12b to 42b, respectively. It is arranged to do. The fourth side walls 12d to 42d are intended as the fourth side walls 12d, 22d, 32d, and 42d. With the above configuration, the gap between the vacuum insulation side panels 11 to 41 and the side cases 12 to 42 becomes large. Therefore, with respect to the side plates 1 to 4, the vacuum heat insulating side panels 11 to 41 can be taken in and out from the side cases 12 to 42, respectively.

Other embodiments of the present invention will be described below. For convenience of explanation, the same reference numerals will be added to the members having the same functions as the members described in the above embodiment, and the description will not be repeated.

図４は、本実施形態に係る定温保管容器に備えられた断熱容器本体１０Ａの概略構成を示す水平断面図である。図４に示されるように、断熱容器本体１０Ａは、弾性体１３〜４３を備えた点が前記実施形態１と異なる。 FIG. 4 is a horizontal cross-sectional view showing a schematic configuration of a heat insulating container main body 10A provided in the constant temperature storage container according to the present embodiment. As shown in FIG. 4, the heat insulating container main body 10A is different from the first embodiment in that the elastic bodies 13 to 43 are provided.

図４に示されるように、断熱容器本体１０Ａの角部Ａにおいて、真空断熱側面パネル１１と第３側壁１２ｃとの隙間に弾性体１３が配置されている。同様に、角部Ｂ〜Ｄそれぞれにおいて、真空断熱側面パネル２１〜４１と第３側壁２２ｃ〜４２ｃとの隙間に弾性体２３〜４３が配置されている。 As shown in FIG. 4, in the corner portion A of the heat insulating container main body 10A, the elastic body 13 is arranged in the gap between the vacuum heat insulating side panel 11 and the third side wall 12c.

The elastic bodies 13 to 43 bring the vacuum heat insulating side panels 11 to 41 into a state of being urged toward the second side walls 12b to 42b, respectively.
