Description

保冷箱Cold box
　本発明は、物品を収容して保冷する保冷箱に関し、特に、折り畳み可能な保冷箱に関する。 The present invention relates to a cold box that accommodates articles and keeps them cool, and more particularly to a foldable cold box.
　物流システムにおいては、物品を一定温度、例えば低温で輸送するサービスが、陸送、空輸を問わず提供されている。物品を低温で輸送する場合は、例えば、断熱性を有する保冷箱に物品とともに保冷材を収容し、この保冷材の冷気によって物品を保冷しながら輸送することが考えられる。また、倉庫内にて物品を低温で保管する場合も同様に、断熱性を有する保冷箱に物品とともに保冷材を収容し、保冷材の冷気によって物品を保冷しながら保管することが考えられる。 In the logistics system, a service for transporting goods at a constant temperature, for example, a low temperature, is provided for both land transportation and air transportation. In the case of transporting an article at a low temperature, for example, it is conceivable to store a cold insulation material together with the article in a cold insulation box having heat insulation properties, and transport the article while keeping the article cool by the cold air of the cold insulation material. Similarly, when storing an article in a warehouse at a low temperature, it is conceivable to store the cold insulating material together with the article in a heat insulating cool box and store the article while keeping the cold by the cold air of the cold insulating material.
　このような保冷箱としては、外箱内に、板状の断熱材を外箱の内壁に重ね合わせるように配置したものが考えられている（例えば、特許文献１参照）。このように外箱となる収納容器内に板状の断熱板を配置した構成の保冷箱を用いることで、断熱性を有する箱体を用いることなく、物品を保冷することができる。 As such a cold box, it is conceivable that a plate-like heat insulating material is arranged in the outer box so as to overlap the inner wall of the outer box (for example, see Patent Document 1). By using a cold box having a structure in which a plate-like heat insulating plate is arranged in a storage container serving as an outer box in this manner, an article can be kept cold without using a box having heat insulation properties.

　近年、上述したように、保冷箱を用いて物品を低温で輸送することが多く行われている。そのため、低温で物品を輸送する場合も、常温で物品を輸送する場合に近い取り扱いやすさが求められている。その１つとして、常温で物品を輸送する際に利用されるコンテナと同様に、保冷箱を素早く容易に折り畳んだり組み立てたりすることが求められる。 In recent years, as described above, articles are often transported at low temperatures using a cold box. Therefore, even when an article is transported at a low temperature, the ease of handling is demanded that is close to that when an article is transported at a normal temperature. As one of them, it is required to fold and assemble a cold box quickly and easily like a container used for transporting articles at room temperature.
　しかしながら、上述したように収納容器内に板状の断熱材を配置した保冷箱を折り畳む場合、例えば、収納容器から断熱材を取り出して収納容器を折り畳むこととなる。そのため、素早く容易に折り畳んだり組み立てたりすることができない。そこで、可撓性を有するシートから収納容器を構成し、収納容器内に板状の断熱材が配置された状態で収納容器を折り畳むことが考えられる。しかしその場合、収納容器が可撓性を有することから、折り畳まれる際にきれいに折り畳まれずにくしゃくしゃになりやすく、折り畳んだり組み立てたりする際に手間取ってしまい、素早く容易に折り畳んだり組み立てたりすることができるとは言い難い。また、収納容器が可撓性を有する場合、収納容器内に配置された板状の断熱材を組み立てにくくなってしまい、これによっても、素早く容易に折り畳んだり組み立てたりすることができるとは言い難い。 However, when a cold box in which a plate-like heat insulating material is arranged in the storage container as described above is folded, for example, the heat insulating material is taken out of the storage container and the storage container is folded. Therefore, it cannot be folded or assembled quickly and easily. Therefore, it is conceivable that the storage container is composed of a flexible sheet, and the storage container is folded in a state where a plate-like heat insulating material is disposed in the storage container. However, in that case, since the storage container has flexibility, it is easy to be crumpled without being folded neatly when folded, and it takes time when folding and assembling, and it can be folded and assembled quickly and easily. It's hard to say. Further, when the storage container has flexibility, it becomes difficult to assemble the plate-like heat insulating material arranged in the storage container, and it is difficult to say that it can be quickly and easily folded and assembled. .
　本発明は、上述したような従来の技術が有する問題点に鑑みてなされたものであって、収納容器内に断熱板が配置された構成において、素早く容易に折り畳んだり組み立てたりすることができる保冷箱を提供することを目的とする。 The present invention has been made in view of the problems of the conventional techniques as described above, and can be quickly and easily folded or assembled in a configuration in which a heat insulating plate is arranged in a storage container. The purpose is to provide a box.
　上記目的を達成するために本発明は、
　天面が開閉自在に構成され、少なくとも側面が可撓性部材からなる直方体または立方体の収納容器と、
　前記収納容器の４つの側面の内側にそれぞれ重ね合わされるように配置され、前記収納容器の底面側の端辺を中心として前記側面の内側に重ね合わされた状態から前記底面に対向する状態まで回動自在に構成された４つの断熱板とを有し、
　前記４つの側面のうち互いに対向する１組の側面はそれぞれ、当該側面の上下の端辺に沿う領域をそれぞれ第１の辺とし、該第１の辺間に第２の辺を共通に有し、前記第１の辺が前記第２の辺よりも長い２つの略等脚台形からなる領域を備え、
　当該領域は、当該領域の外側のうち、前記２つの略等脚台形の脚と当該側面の他の側面との連接辺とで囲まれた領域よりも硬く、かつ、前記第２の辺にて折り畳み可能に構成されている。 In order to achieve the above object, the present invention provides:
A cuboid or cubic storage container having a top surface that can be opened and closed and at least a side surface made of a flexible member;
It is arranged so as to be overlapped inside the four side surfaces of the storage container, and rotates from the state where it is overlapped inside the side surface to the state facing the bottom surface with the end on the bottom side of the storage container as the center. 4 heat insulating plates configured freely,
Each of the pair of side surfaces facing each other among the four side surfaces has a region along the upper and lower end sides of the side surface as a first side, and a second side in common between the first sides. , The first side includes a region having two substantially isosceles trapezoids longer than the second side,
The region is harder than the region surrounded by the two sides of the substantially isosceles trapezoidal leg and the connecting side of the other side surface of the side surface, and the second side. It is configured to be foldable.
　上記のように本発明は、収納容器の４つの側面のうち互いに対向する１組の側面がそれぞれ、その側面の上下の端辺に沿う領域をそれぞれ第１の辺とし、第１の辺間に第２の辺を共通に有し、第１の辺が第２の辺よりも長い２つの略等脚台形からなる領域が、当該領域の外側のうち、２つの略等脚台形の脚と当該側面の他の側面との連接辺とで囲まれた領域よりも硬く、かつ、第２の辺にて折り畳み可能に構成されている。そのため、４つの断熱板を、可撓性部材からなる収納容器の側面に重ね合わされた状態から底面に対向する状態にそれぞれ回動させた後、収納容器の上端部を下方に押し付けるようにすると、収納容器の４つの側面のうち互いに対向する１組の側面においては、２つの略等脚台形からなる領域が、第２の辺となる部分が頂点となって収納容器の内側に向かって凸となるように折り畳まれていくとともに、２つの略等脚台形からなる領域の外形に沿って折り畳まれ、２つの略等脚台形の脚と、その側面の他の側面との連接辺とで囲まれた領域が、略等脚台形からなる２つの領域に挟まれるように折り畳まれていく。そして、１組の側面がこのように折り畳まれていくことで、他の側面においては、１組の側面との連接部分の近傍が、略等脚台形からなる２つの領域に挟まれるように高さ方向中央部分にて折り畳まれていく。これにより、収納容器がくしゃくしゃにならずに決められた形状に折り畳まれていき、保冷箱がきれいに折り畳まれることになる。またその際、２つの略等脚台形からなる領域が硬いことで収納容器の側面が略伸張状態となりやすく、それにより、断熱板を回動させやすくなる。また、このように折り畳まれた保冷箱を組み立てる場合は、収納容器の上端部を上方に引き上げるようにして側面を伸ばした後、４つの断熱板を、底面に対向する状態から側面に重ね合わされた状態にそれぞれ回動させる。 As described above, according to the present invention, a pair of side surfaces facing each other among the four side surfaces of the storage container each have a region along the upper and lower end sides of each side surface as a first side, and between the first sides. A region having two substantially isosceles trapezoids having a second side in common and the first side being longer than the second side is composed of two substantially isosceles trapezoidal legs and the outside of the region. The side surface is harder than the region surrounded by the connecting side with the other side surface, and can be folded at the second side. Therefore, after rotating each of the four heat insulating plates from the state of being superimposed on the side surface of the storage container made of a flexible member to the state facing the bottom surface, the upper end of the storage container is pressed downward. In one set of side surfaces facing each other among the four side surfaces of the storage container, the region formed of two substantially isosceles trapezoids is convex toward the inside of the storage container with the second side as a vertex. And is folded along the outline of the region consisting of two substantially isosceles trapezoids, and is surrounded by two substantially isosceles trapezoidal legs and the connecting side of the other side of the side The region is folded so as to be sandwiched between two regions having a substantially isosceles trapezoid. In addition, by folding one set of side surfaces in this way, on the other side, the vicinity of the connecting portion with the set of side surfaces is so high that it is sandwiched between two regions that are substantially isosceles trapezoids. It is folded at the center in the vertical direction. Accordingly, the storage container is folded into a predetermined shape without being crumpled, and the cold box is folded neatly. Further, at that time, since the region composed of the two substantially isosceles trapezoids is hard, the side surface of the storage container is likely to be in the substantially extended state, thereby easily rotating the heat insulating plate. In addition, when assembling the cold box folded in this way, after extending the side by pulling up the upper end of the storage container, the four heat insulating plates were superimposed on the side from the state facing the bottom. Rotate to each state.
　このように、４つの断熱板を回動させるとともに、収納容器の上端部を下方に押し付けるようにするだけで、収納容器がくしゃくしゃにならずに決められた形状に折り畳まれることとなるとともに、２つの略等脚台形からなる領域が硬いことで収納容器の側面が略伸張状態となりやすい。それにより、素早く容易に保冷箱を折り畳んだり組み立てたりすることができる。 In this way, the four heat insulating plates are rotated and the upper end portion of the storage container is pressed downward, so that the storage container is folded into a predetermined shape without being crumpled. The side surface of the storage container is likely to be substantially stretched because the region composed of two substantially isosceles trapezoids is hard. Thereby, the cold box can be folded and assembled quickly and easily.
　本発明においては、収納容器の４つの側面のうち互いに対向する１組の側面がそれぞれ、その側面の上下の端辺をそれぞれ第１の辺とし、第１の辺間に第２の辺を共通に有し、第１の辺が第２の辺よりも長い２つの略等脚台形からなる領域が、当該領域の外側のうち、２つの略等脚台形の脚と当該側面の他の側面との連接辺とで囲まれた領域よりも硬く、かつ、第２の辺にて折り畳み可能に構成されているため、４つの断熱板を、収納容器の側面に重ね合わされた状態から底面に対向する状態にそれぞれ回動させた後、収納容器の上端部を下方に押し付けるようにすることで、収納容器がくしゃくしゃにならずに決められた形状に折り畳まれることとなる。また、収納容器の上端部を上方に引き上げるようにして側面を伸ばした後、４つの断熱板を、底面に対向する状態から側面に重ね合わされた状態にそれぞれ回動させることで、保冷箱が組み立てられることとなる。このように、収納容器内に断熱板が配置された構成において、素早く容易に折り畳んだり組み立てたりすることができる。また、２つの略等脚台形からなる領域が硬いことで、保冷箱を組み立てる際に収納容器の側面が略伸張状態となりやすくなる。それにより、断熱板を回動させやすく、保冷箱を素早く容易に組み立てることができる。 In the present invention, among the four side surfaces of the storage container, each of the pair of side surfaces facing each other has the upper and lower end sides of the side surfaces as the first side, and the second side is shared between the first sides. A region formed of two substantially isosceles trapezoids having a first side longer than the second side, and two of the substantially isosceles trapezoidal legs and the other side surface of the side surface outside the region. Since it is harder than the region surrounded by the connecting sides of the two and foldable at the second side, the four heat insulating plates are opposed to the bottom surface from the state of being superimposed on the side surface of the storage container. After each rotation to the state, the upper end portion of the storage container is pressed downward, so that the storage container is folded into a predetermined shape without being crumpled. In addition, after extending the side by pulling the upper end of the storage container upward, the four heat insulation plates are rotated from the state facing the bottom to the state superimposed on the side, thereby assembling the cold box. Will be. As described above, in the configuration in which the heat insulating plate is arranged in the storage container, it can be quickly and easily folded or assembled. Moreover, since the area | region which consists of two substantially isosceles trapezoids is hard, when assembling a cold box, the side surface of a storage container becomes easy to be in a substantially expansion | extension state. Thereby, it is easy to rotate the heat insulating plate, and the cold box can be assembled quickly and easily.

　蓋部１１ａ，１１ｂは、可撓性を有する２枚のアルミシートが重ね合わされて構成されている。蓋部１１ａは、側面１２ｃの天面側の端辺と連接している。また、蓋部１１ｂは、側面１２ｃに対向する側面１２ｄの天面側の端辺と連接している。そして、蓋部１１ａ，１１ｂは、側面１２ｃ，１２ｄとの連接辺を中心としてそれぞれ回動することで、収納容器の天面が開閉自在に構成されている。そのため、蓋部１１ａ，１１ｂは、側面１２ｃ，１２ｄとの連接方向の長さが、蓋部１１ａ，１１ｂが閉じられた場合にその一部が重なる長さとなっている。 The lid portions 11a and 11b are configured by overlapping two flexible aluminum sheets. The lid portion 11a is connected to the end of the side surface 12c on the top surface side. Moreover, the cover part 11b is connected with the edge of the top | upper surface side of the side surface 12d facing the side surface 12c. And the cover parts 11a and 11b are each comprised centering on the connection side with the side surfaces 12c and 12d, and the top | upper surface of a storage container is comprised so that opening and closing is possible.

Further, a handle 29 is attached between the lid portion 11a and the hook-and-loop fastener 31 so that the lid portion 11a can be easily opened.
　底面１３は、可撓性を有するシートで構成されている。底面１３は、収納容器の内側となる面に、底面１３に対向しない面の全面がアルミシートで覆われた断熱板２３が取り付けられている。また、底面１３の収納容器の外側となる面には、側面１２ａ，１２ｂとの連接辺の近傍にベルト２８が取り付けられている。このベルト２８は、一端が底面１３に取り付けられ、他端の一方の面に面ファスナー３３が取り付けられている。 The bottom surface 13 is composed of a flexible sheet. The bottom surface 13 is attached to the inner surface of the storage container with a heat insulating plate 23 whose entire surface not facing the bottom surface 13 is covered with an aluminum sheet. Further, a belt 28 is attached to the surface of the bottom surface 13 which is the outside of the storage container, in the vicinity of the connecting side with the side surfaces 12a and 12b. One end of the belt 28 is attached to the bottom surface 13, and a surface fastener 33 is attached to one surface of the other end.
　側面１２ａ，１２ｂはそれぞれ、互いに対向して配置され、その一部の領域を除いて可撓性を有する２枚のアルミシートが重ね合わされて構成されている。側面１２ａ，１２ｂの天面側の端辺に沿う領域を第１の辺とした等脚台形領域１４ａと、側面１２ａ，１２ｂの底面１３側の端辺から所定の幅を有する領域と、その領域の底面１３とは反対側の辺を第１の辺とする等脚台形領域１４ｂとが、２枚のアルミシートが重ね合わされて構成されている。なお、等脚台形領域１４ａ，１４ｂは、第１の辺間に第２の辺を共通に有し、第１の辺が第２の辺よりも長くなっている。また、等脚台形領域１４ａ，１４ｂの脚と側面１２ａ，１２ｂの側面１２ｃ，１２ｄとの連接辺とで囲まれた三角領域１６ａ，１６ｂが、１枚のアルミシートから構成されている。２枚のアルミシートが重ね合わされた等脚台形領域１４ａ，１４ｂは、その周囲にステッチ１５が形成されている。それにより、三角領域１６ａ，１６ｂとの境界部分及び等脚台形領域１４ａ，１４ｂの境界部分が折り畳まれやすくなっている。これにより、互いに対向する１組の側面１２ａ，１２ｂはそれぞれ、側面１２ａ，１２ｂの上下の端辺に沿う領域をそれぞれ第１の辺とし、第１の辺間に第２の辺を共通に有し、第１の辺が第２の辺よりも長い２つの等脚台形領域１４ａ，１４ｂからなる領域が、等脚台形領域１４ａ，１４ｂの外側のうち、等脚台形領域１４ａ，１４ｂの脚と側面１２ａ，１２ｂの側面１２ｃ，１２ｄとの連接辺とで囲まれた領域よりも硬く、かつ、第２の辺にて折り畳み可能に構成されている。また、等脚台形領域１４ａのうち収納容器の外側となる面に面ファスナー３２が取り付けられている。側面１２ａ，１２ｂには、収納容器の内側となる面に重ね合わされるように断熱板２２ａ，２２ｂが配置されている。また、側面１２ａ，１２ｂのうち、収納容器の天面側の端辺には、フラップ部５１ａ，５１ｂがそれぞれ連接している。 Each of the side surfaces 12a and 12b is disposed so as to face each other, and is configured by overlapping two flexible aluminum sheets excluding a part of the side surfaces. An isosceles trapezoidal region 14a having a region along the top side of the side surfaces 12a, 12b as a first side, a region having a predetermined width from the side of the side surface 12a, 12b on the bottom surface 13 side, and the region An isosceles trapezoidal region 14b having a side opposite to the bottom surface 13 as a first side is formed by overlapping two aluminum sheets. The isosceles trapezoidal regions 14a and 14b have a second side in common between the first sides, and the first side is longer than the second side. Further, the triangular regions 16a and 16b surrounded by the legs of the isosceles trapezoidal regions 14a and 14b and the connecting sides of the side surfaces 12c and 12d of the side surfaces 12a and 12b are composed of a single aluminum sheet. The isosceles trapezoidal regions 14a and 14b in which two aluminum sheets are overlapped have stitches 15 formed around them. Thereby, the boundary portion between the triangular regions 16a and 16b and the boundary portion between the isosceles trapezoidal regions 14a and 14b are easily folded. As a result, each of the pair of side surfaces 12a and 12b facing each other has a region along the upper and lower end sides of the side surfaces 12a and 12b as a first side, and a common second side between the first sides. An area composed of two isosceles trapezoidal areas 14a and 14b whose first side is longer than the second side is the outside of the isosceles trapezoidal areas 14a and 14b and the legs of the isosceles trapezoidal areas 14a and 14b. The side surfaces 12a and 12b are configured to be harder than a region surrounded by the side connected to the side surfaces 12c and 12d and to be foldable at the second side. Moreover, the hook-and-loop fastener 32 is attached to the surface which becomes the outer side of a storage container among the isosceles trapezoid area | regions 14a. The heat insulating plates 22a and 22b are disposed on the side surfaces 12a and 12b so as to be superimposed on the inner surface of the storage container. Further, of the side surfaces 12a and 12b, the flap portions 51a and 51b are connected to the end on the top surface side of the storage container.
　フラップ部５１ａ，５１ｂには、フラップ部５１ａ，５１ｂが折り畳まれた場合に収納容器の内側となる面に、側面１２ａ，１２ｂとの連接辺に沿って面ファスナー３６が取り付けられている。また、フラップ部５１ａ，５１ｂには、フラップ部５１ａ，５１ｂが折り畳まれた場合に収納容器の外側となる面のうちフラップ部５１ａ，５１ｂの長手方向中央部に面ファスナー３５が取り付けられている。 A hook-and-loop fastener 36 is attached to the flap portions 51a and 51b along the connecting side with the side surfaces 12a and 12b on the inner surface of the storage container when the flap portions 51a and 51b are folded. In addition, a hook-and-loop fastener 35 is attached to the flap portions 51a and 51b at the center in the longitudinal direction of the flap portions 51a and 51b on the outer surface of the storage container when the flap portions 51a and 51b are folded.
　断熱板２２ａ，２２ｂは、その全面がアルミシートで覆われており、側面１２ａ，１２ｂの幅と同等の幅を有している。断熱板２２ａ，２２ｂは、側面１２ａ，１２ｂの高さから断熱板２３及び後述する断熱板２２ｃ，２２ｄを重ね合わせた厚さを減じた高さを有している。断熱板２２ａ，２２ｂは、断熱板２３の端辺に取り付けられた非折り曲げ部２５上に起立した状態で側面１２ａ，１２ｂに重ね合わされ、非折り曲げ部２５との当接面のうち重ね合わされた側面１２ａ，１２ｂとは反対側の辺が非折り曲げ部２５に縫合等によって接合されている。それにより、断熱板２２ａ，２２ｂはそれぞれ、底面１３側の端辺を中心として側面１２ａ，１２ｂに重ね合わされた状態から底面１３に対向する状態まで回動自在に構成されている。 The entire surface of the heat insulating plates 22a and 22b is covered with an aluminum sheet and has a width equivalent to the width of the side surfaces 12a and 12b. The heat insulating plates 22a and 22b have a height obtained by subtracting the thickness of the heat insulating plate 23 and heat insulating plates 22c and 22d described later from the height of the side surfaces 12a and 12b. The heat insulating plates 22 a and 22 b are overlaid on the side surfaces 12 a and 12 b in a state of standing on the non-bending portion 25 attached to the end side of the heat insulating plate 23, and the side surfaces overlapped among the contact surfaces with the non-bending portion 25. The side opposite to 12a and 12b is joined to the unfolded portion 25 by stitching or the like. Thereby, each of the heat insulating plates 22a and 22b is configured to be rotatable from the state of being overlaid on the side surfaces 12a and 12b to the state of being opposed to the bottom surface 13 with the end on the bottom surface 13 side as the center.
　非折り曲げ部２５は、その高さが、断熱板２２ｃ，２２ｄを重ね合わせた厚さと同等のものとなっている。それにより、断熱板２２ｃ，２２ｄが底面１３に対向する状態とされた後に断熱板２２ａ，２２ｂが底面１３と対向する状態とされると、図２ｂに示すように、断熱板２２ａ，２２ｂの上面が底面１３と略平行な状態となる。なお、非折り曲げ部２５は、断熱板２２ａ，２２ｂと同等の材料から構成することが考えられるが、本願発明における断熱板を構成するものではない。 The height of the non-bending portion 25 is equivalent to the thickness of the heat insulating plates 22c and 22d overlapped. Accordingly, when the heat insulating plates 22a and 22b are opposed to the bottom surface 13 after the heat insulating plates 22c and 22d are opposed to the bottom surface 13, as shown in FIG. 2b, the upper surfaces of the heat insulating plates 22a and 22b. Is substantially parallel to the bottom surface 13. In addition, although it is possible to comprise the non-bending part 25 from the material equivalent to the heat insulation board 22a, 22b, it does not comprise the heat insulation board in this invention.
　側面１２ｃ，１２ｄは、互いに対向して配置され、可撓性を有する２枚のアルミシートが重ね合わされて構成されている。側面１２ｃ，１２ｄには、収納容器の内側となる面に重ね合わされるように断熱板２２ｃ，２２ｄが配置されている。 The side surfaces 12c and 12d are arranged to face each other, and are configured by overlapping two flexible aluminum sheets. The heat insulating plates 22c and 22d are disposed on the side surfaces 12c and 12d so as to be superimposed on the inner surface of the storage container.
　断熱板２２ｃ，２２ｄは、その全面がアルミシートで覆われており、側面１２ｃ，１２ｄの幅から断熱板２２ａ，２２ｂの厚さを減じた幅を有している。断熱板２２ｃは、側面１２ｃの高さから断熱板２３の厚さを減じた高さを有している。断熱板２２ｃは、断熱板２３の端辺に起立した状態で側面１２ｃに重ね合わされ、断熱板２３との当接面のうち側面１２ｃとは反対側の辺が断熱板２３に縫合等によって接合されている。それにより、断熱板２２ｃは、底面１３側の端辺を中心として側面１２ｃに重ね合わされた状態から底面１３に対向する状態まで回動自在に構成されている。断熱板２２ｄは、側面１２ｄの高さから断熱板２２ｃ及び断熱板２３の厚さを減じた高さを有している。断熱板２２ｄは、断熱板２３の端辺に取り付けられた非折り曲げ部２４上に起立した状態で側面１２ｄに重ね合わされ、非折り曲げ部２４との当接面のうち側面１２ｄとは反対側の辺が非折り曲げ部２４に縫合等によって接合されている。それにより、断熱板２２ｄは、底面１３側の端辺を中心として側面１２ｄに重ね合わされた状態から底面１３に対向する状態まで回動自在に構成されている。なお、非折り曲げ部２４は、断熱板２２ｄと同等の材料から構成することが考えられるが、本願発明における断熱板を構成するものではない。 The entire surface of the heat insulating plates 22c and 22d is covered with an aluminum sheet, and has a width obtained by subtracting the thickness of the heat insulating plates 22a and 22b from the width of the side surfaces 12c and 12d. The heat insulating plate 22c has a height obtained by subtracting the thickness of the heat insulating plate 23 from the height of the side surface 12c. The heat insulating plate 22c is superposed on the side surface 12c while standing on the end side of the heat insulating plate 23, and the side opposite to the side surface 12c of the contact surface with the heat insulating plate 23 is joined to the heat insulating plate 23 by sewing or the like. ing. Accordingly, the heat insulating plate 22c is configured to be rotatable from a state where the heat insulating plate 22c is superimposed on the side surface 12c with the end on the bottom surface 13 side as a center to a state where the heat insulating plate 22c faces the bottom surface 13. The heat insulating plate 22d has a height obtained by subtracting the thickness of the heat insulating plate 22c and the heat insulating plate 23 from the height of the side surface 12d. The heat insulating plate 22d is superposed on the side surface 12d while standing on the non-bending portion 24 attached to the end side of the heat insulating plate 23, and the side of the contact surface with the non-folding portion 24 opposite to the side surface 12d. Is joined to the non-folded portion 24 by stitching or the like. Accordingly, the heat insulating plate 22d is configured to be rotatable from a state where the heat insulating plate 22d is superimposed on the side surface 12d with the end on the bottom surface 13 side as a center to a state where the heat insulating plate 22d faces the bottom surface 13. In addition, although it is possible to comprise the non-bending part 24 from the material equivalent to the heat insulation board 22d, it does not comprise the heat insulation board in this invention.
　断熱板２２ｃ，２２ｄは、それぞれが底面１３に対向する状態とされると、一部が互いに重なり合う高さを有している。そのため、非折り曲げ部２４の高さが、断熱板２２ｃの厚さと同等のものとなっており、それにより、断熱板２２ｃが底面１３に対向する状態とされた後に断熱板２２ｄが底面１３と対向する状態とされると、図３ｂに示すように、断熱板２２ｄの上面が底面１３と略平行な状態となる。 When the heat insulating plates 22c and 22d are in a state of facing the bottom surface 13 respectively, the heat insulating plates 22c and 22d have a height at which some of them overlap each other. Therefore, the height of the non-bending portion 24 is equivalent to the thickness of the heat insulating plate 22c, whereby the heat insulating plate 22d is opposed to the bottom surface 13 after the heat insulating plate 22c is opposed to the bottom surface 13. In this state, the upper surface of the heat insulating plate 22d is substantially parallel to the bottom surface 13 as shown in FIG. 3b.

　図１ａ～図１ｃ、図２ａ、図２ｂ、図３ａ及び図３ｂに示した保冷箱１において断熱板２２ｃ，２２ｄを倒していく場合はまず、図５ａに示すように、断熱板２２ｃを、底面１３側の端辺の断熱板２３との接合部分を中心として、側面１２ｃに重ね合わされた状態から回動させ、断熱板２３に当接させて断熱板２３上に載置された状態とする。これにより、断熱板２２ｃは、底面１３に対向した状態となる。 When the heat insulating plates 22c and 22d are brought down in the cool box 1 shown in FIGS. 1a to 1c, 2a, 2b, 3a and 3b, first, as shown in FIG. Rotating from the state of being overlapped with the side surface 12c around the joint portion with the heat insulating plate 23 on the side edge on the 13th side, brought into contact with the heat insulating plate 23 and placed on the heat insulating plate 23. Thereby, the heat insulation board 22c will be in the state facing the bottom face 13. FIG.
　次に、図５ｂに示すように、断熱板２２ｄを、底面１３側の端辺の非折り曲げ部２４との接合部分を中心として、側面１２ｄに重ね合わされた状態から回動させていく。すると、上述したように、断熱板２２ｃ，２２ｄは、それぞれが底面１３に対向する状態とされた場合に、一部が互いに重なり合う高さを有していることから、図５ｃに示すように、断熱板２２ｄの非折り曲げ部２４との接合部分とは反対側の辺側の領域が、断熱板２２ｃに当接し、底面１３に対向した状態となる。この際、非折り曲げ部２４の高さが、断熱板２２ｃの厚さと同等のものとなっているため、断熱板２２ｄの上面が底面１３と略平行な状態となる。 Next, as shown in FIG. 5 b, the heat insulating plate 22 d is rotated from the state where it is overlapped with the side surface 12 d around the joint portion with the non-bent portion 24 at the end on the bottom surface 13 side. Then, as described above, when each of the heat insulating plates 22c and 22d is in a state of facing the bottom surface 13, as shown in FIG. The region on the side opposite to the joint portion of the heat insulating plate 22d with the non-bent portion 24 is in contact with the heat insulating plate 22c and faces the bottom surface 13. At this time, since the height of the non-bending portion 24 is equivalent to the thickness of the heat insulating plate 22c, the upper surface of the heat insulating plate 22d is substantially parallel to the bottom surface 13.
　このようにして断熱板２２ｃ，２２ｄを倒して底面１３と対向する状態とした後、図４ｂに示すように、断熱板２２ａ，２２ｂを倒していく。 In this way, after the heat insulating plates 22c and 22d are tilted to face the bottom surface 13, the heat insulating plates 22a and 22b are tilted as shown in FIG. 4b.
　図６ａ及び図６ｂは、図１ａ～図１ｃ、図２ａ、図２ｂ、図３ａ及び図３ｂに示した保冷箱１において断熱板２２ａ，２２ｂを倒していく際の作用を説明するための断面図である。 6a and 6b are cross-sectional views for explaining the action when the heat insulating plates 22a and 22b are tilted in the cold insulation box 1 shown in FIGS. 1a to 1c, 2a, 2b, 3a and 3b. It is.
　図１ａ～図１ｃ、図２ａ、図２ｂ、図３ａ及び図３ｂに示した保冷箱１において、断熱板２２ｃ，２２ｄを上記のようにして倒して底面１３と対向する状態とした後、断熱板２２ａ，２２ｂを倒していく場合は、断熱板２２ａ，２２ｂがそれぞれ、底面１３に対向する状態とされた場合に、互いに重なり合わない高さを有していることから、図６ａに示すように、断熱板２２ａ，２２ｂを同時に倒していくことができる。 In the cold box 1 shown in FIGS. 1a to 1c, 2a, 2b, 3a and 3b, the heat insulating plates 22c and 22d are brought down to face the bottom surface 13 as described above. As shown in FIG. 6a, when 22a and 22b are brought down, the heat insulating plates 22a and 22b have a height that does not overlap each other when they are in a state of facing the bottom surface 13, respectively. The heat insulating plates 22a and 22b can be defeated at the same time.
　そして、上述したように、底面１３に取り付けられた断熱板２３上には、その一部が重なり合った状態で倒された断熱板２２ｃ，２２ｄが載置された状態となっているため、図６ｂに示すように、断熱板２２ｃ，２２ｄのうち上側となった断熱板２２ｄ上に断熱板２２ａ，２２ｂが載置された状態となる。その際、上述したように、非折り曲げ部２５の高さが、断熱板２２ｃ，２２ｄを重ね合わせた厚さと同等のものとなっているため、断熱板２２ａ，２２ｂが倒されて底面１３に対向した状態においては、断熱板２２ａ，２２ｂの上面が底面１３と略平行な状態となる。 And as above-mentioned, since it is in the state in which the heat insulation board 22c, 22d which fell down in the state with which the one part overlapped was mounted on the heat insulation board 23 attached to the bottom face 13, FIG. 6b. As shown, the heat insulating plates 22a and 22b are placed on the heat insulating plate 22d which is the upper side of the heat insulating plates 22c and 22d. At that time, as described above, since the height of the non-bending portion 25 is equal to the thickness of the heat insulating plates 22c and 22d overlapped, the heat insulating plates 22a and 22b are tilted to face the bottom surface 13. In this state, the upper surfaces of the heat insulating plates 22a and 22b are substantially parallel to the bottom surface 13.
　このようにして断熱板２２ａ～２２ｄが全て倒されて底面１３に対向する状態とされると、側面１２ａ～１２ｄがアルミシートから構成されていることで側面１２ａ～１２ｄの自立性がなくなり、収納容器の上端部を下方に押し付けるようにすると、図４ｃに示すように、収納容器を折り畳むことができる。 When the heat insulating plates 22a to 22d are all turned down and face the bottom surface 13 in this way, the side surfaces 12a to 12d are made of an aluminum sheet, so that the side surfaces 12a to 12d are not self-supporting. When the upper end of the container is pressed downward, the storage container can be folded as shown in FIG. 4c.
　ここで、収納容器を折り畳む際の側面１２ａ～１２ｄの作用について説明する。 Here, the operation of the side surfaces 12a to 12d when the storage container is folded will be described.
　図７ａ～図７ｃは、図１ａ～図１ｃ、図２ａ、図２ｂ、図３ａ及び図３ｂに示した保冷箱１において収納容器を折り畳む際の側面１２ａ～１２ｄの作用を説明するための図であり、保冷箱１を天面側から見た図である。 7a to 7c are views for explaining the action of the side surfaces 12a to 12d when the storage container is folded in the cold box 1 shown in FIGS. 1a to 1c, 2a, 2b, 3a and 3b. It is the figure which looked at the cold storage box 1 from the top | upper surface side.
　図１ａ～図１ｃ、図２ａ、図２ｂ、図３ａ及び図３ｂに示した保冷箱１は、上述したように、収納容器の４つの側面のうち互いに対向する１組の側面１２ａ，１２ｂがそれぞれ、その側面１２ａ，１２ｂの上下の端辺に沿う領域をそれぞれ第１の辺とし、第１の辺間に第２の辺を共通に有し、第１の辺が第２の辺よりも長い２つの等脚台形領域１４ａ，１４ｂから構成される領域が、等脚台形領域１４ａ，１４ｂの外側のうち、２つの等脚台形の脚と側面１２ａ，１２ｂの側面１２ｃ，１２ｄとの連接辺とで囲まれた三角領域１６ａ，１６ｂよりも硬く、かつ、第２の辺にて折り畳み可能に構成されている。そのため、側面１２ａ，１２ｂにおいては、図７ａに示すように折り畳まれていない状態から、収納容器の上端部を下方に押し付けるようにすると、図７ｂに示すように、２つの等脚台形領域１４ａ，１４ｂが、第２の辺となる部分が頂点となって収納容器の内側に向かって凸となるように折り畳まれていくとともに、側面１２ａ，１２ｂが２つの等脚台形領域１４ａ，１４ｂの外形に沿って折り畳まれ、２つの略等脚台形の脚と、側面１２ａ，１２ｂの側面１２ｃ，１２ｄとの連接辺とで囲まれた三角領域１６ａ，１６ｂが、等脚台形領域１４ａ，１４ｂに挟まれるように折り畳まれていく。 As described above, the cold box 1 shown in FIGS. 1a to 1c, 2a, 2b, 3a, and 3b includes a pair of side surfaces 12a and 12b that face each other among the four side surfaces of the storage container. The regions along the upper and lower end sides of the side surfaces 12a and 12b are respectively defined as first sides, the second side is shared between the first sides, and the first side is longer than the second side. The region composed of the two isosceles trapezoidal regions 14a and 14b is a connection side between the two isosceles trapezoidal regions 14a and 14b and the side surfaces 12c and 12d of the side surfaces 12a and 12b. It is harder than the triangular areas 16a and 16b surrounded by, and is foldable on the second side. Therefore, on the side surfaces 12a and 12b, when the upper end portion of the storage container is pressed downward from the unfolded state as shown in FIG. 7a, as shown in FIG. 14b is folded so that the portion serving as the second side becomes a vertex and protrudes toward the inside of the storage container, and the side surfaces 12a and 12b have the outer shapes of the two isosceles trapezoidal regions 14a and 14b. The triangular regions 16a and 16b, which are folded along the two sides and surrounded by the two substantially isosceles trapezoidal legs and the connecting sides of the side surfaces 12c and 12d of the side surfaces 12a and 12b, are sandwiched between the isosceles trapezoidal regions 14a and 14b. It will be folded.
　そして、側面１２ａ，１２ｂがこのように折り畳まれていくことで、図７ｃに示すように、側面１２ｃ，１２ｄにおいては、側面１２ａ，１２ｂとの連接部分の近傍が、等脚台形領域１４ａ，１４ｂに挟まれるように横方向に二つ折りに折り畳まれていく。 Then, by folding the side surfaces 12a and 12b in this way, as shown in FIG. 7c, in the side surfaces 12c and 12d, the vicinity of the connecting portion with the side surfaces 12a and 12b is the isosceles trapezoidal regions 14a and 14b. It is folded in half so that it is sandwiched between the two.
　このようにして側面１２ａ～１２ｄが折り畳まれた後、図４ｄに示すように、蓋部１１ｂを閉じた後に蓋部１１ａを閉じる。そして、蓋部１１ａの面ファスナー３１と蓋部１１ｂの面ファスナーとを接合させる。また、フラップ部５１ａ，５１ｂを折り畳んで蓋部１１ａ，１１ｂの面ファスナーにフラップ部５１ａ，５１ｂの面ファスナー３６を接合させる。さらに、底面１３に取り付けられたベルト２８を保冷箱１の側面１２ａ，１２ｂにかけてベルト２８の面ファスナー３３とフラップ部５１ａ，５１ｂの面ファスナー３５とを接合させ、保冷箱１を折り畳み状態とする。 After the side surfaces 12a to 12d are folded in this way, the lid portion 11a is closed after the lid portion 11b is closed as shown in FIG. 4d. And the hook_and_loop | surface fastener 31 of the cover part 11a and the hook_and_loop | surface fastener of the cover part 11b are joined. Further, the flap portions 51a and 51b are folded, and the surface fasteners 36 of the flap portions 51a and 51b are joined to the surface fasteners of the lid portions 11a and 11b. Further, the belt 28 attached to the bottom surface 13 is applied to the side surfaces 12a and 12b of the cool box 1 to join the surface fastener 33 of the belt 28 and the surface fastener 35 of the flap portions 51a and 51b, so that the cool box 1 is folded.
　このように保冷箱１が折り畳まれることになるが、側面１２ａ，１２ｂが上記のような構成を有しているため、４つの断熱板２２ａ～２２ｄを、収納容器の側面１２ａ～１２ｄに重ね合わされた状態から底面１３に対向する状態にそれぞれ回動させた後、収納容器の上端部を下方に押し付けるようにすることで、収納容器がくしゃくしゃにならずに決められた形状に折り畳まれていく。それにより、断熱板を有する構成においても素早く容易に折り畳むことができる。 In this way, the cold box 1 is folded, but since the side surfaces 12a and 12b have the above-described configuration, the four heat insulating plates 22a to 22d are overlapped with the side surfaces 12a to 12d of the storage container. After rotating from the raised state to the state facing the bottom surface 13, the upper end portion of the storage container is pressed downward, whereby the storage container is folded into a predetermined shape without being crumpled. Thereby, it can fold quickly and easily also in the structure which has a heat insulating board.
　上述したようにして折り畳まれた保冷箱１は、側面１２ｄが上側となるように抱えた状態で取っ手２９を掴めば、蓋部１１ａ，１１ｂが開くことなく簡単に持ち運ぶことができる。 The cold box 1 folded as described above can be easily carried without opening the lid portions 11a and 11b if the handle 29 is grasped with the side surface 12d held upward.
　なお、等脚台形領域１４ａ，１４ｂは、第１の辺と第２の辺とが平行とならず、また、脚部が等しい長さとならない台形に近い形状であってもよく、これらを含めて略等脚台形領域と定義する。 In addition, the isosceles trapezoidal regions 14a and 14b may have a shape close to a trapezoid in which the first side and the second side are not parallel and the leg portions do not have the same length. It is defined as a substantially isosceles trapezoidal region.
　次に、上記のようにして折り畳まれた保冷箱１の組み立て方法について説明する。 Next, a method for assembling the cold box 1 folded as described above will be described.
　図８ａ～図８ｄは、図１ａ～図１ｃ、図２ａ、図２ｂ、図３ａ及び図３ｂに示した保冷箱１の組み立て方法を説明するための外観斜視図である。 FIGS. 8a to 8d are external perspective views for explaining a method of assembling the cold box 1 shown in FIGS. 1a to 1c, 2a, 2b, 3a, and 3b.
　上記のようにして折り畳まれた保冷箱１を組み立てる場合はまず、図８ａに示すように、フラップ部５１ａ，５１ｂの面ファスナー３５からベルト２８の面ファスナー３３を剥離し、蓋部１１ａ，１１ｂの面ファスナーからフラップ部５１ａ，５１ｂの面ファスナー３６を剥離してフラップ部５１ａ，５１ｂを開く。そしてさらに、蓋部１１ａの面ファスナー３１から蓋部１１ｂの面ファスナーを剥離して蓋部１１ａ，１１ｂを開く。 When assembling the cold box 1 folded as described above, first, as shown in FIG. 8a, the hook-and-loop fastener 33 of the belt 28 is peeled off from the hook-and-loop fastener 35 of the flap portions 51a and 51b, and the lid portions 11a and 11b. The surface fasteners 36 of the flap portions 51a and 51b are peeled off from the surface fastener to open the flap portions 51a and 51b. Further, the surface fastener of the lid portion 11b is peeled from the surface fastener 31 of the lid portion 11a to open the lid portions 11a and 11b.
　そして、収納容器の上端部を上方に引き上げるようにして側面を伸ばした後、図８ｂに示すように、断熱板２２ａ，２２ｂをそれぞれ、底面１３側の端辺の非折り曲げ部２５との接合部分を中心として、底面１３に対向した状態から回動させ、側面１２ａ，１２ｂに重ね合わされた状態とする。この際、側面１２ａ，１２ｂが、等脚台形領域１４ａ，１４ｂが硬いことで略伸張状態となりやすくなり、断熱板２２ａ，２２ｂを、底面１３に対向した状態から側面１２ａ，１２ｂに重ね合わされた状態まで回動させやすくなる。 And after extending the side surface by pulling up the upper end of the storage container, as shown in FIG. 8b, each of the heat insulating plates 22a and 22b is joined to the non-bent portion 25 on the side of the bottom surface 13 side. The center is turned from the state facing the bottom surface 13 and is superposed on the side surfaces 12a and 12b. At this time, the side surfaces 12a and 12b tend to be substantially stretched because the isosceles trapezoidal regions 14a and 14b are hard, and the heat insulating plates 22a and 22b are superposed on the side surfaces 12a and 12b from the state facing the bottom surface 13. It becomes easy to rotate to.
　断熱板２２ａ，２２ｂを側面１２ａ，１２ｂに重ね合わされた状態とした後、図８ｃに示すように、断熱板２２ｄを、底面１３側の端辺の非折り曲げ部２４との接合部分を中心として、底面１３に対向した状態から回動させ、側面１２ｄに重ね合わされた状態とする。また、断熱板２２ｃを、底面１３側の端辺の断熱板２３との接合部分を中心として、底面１３に対向した状態から回動させ、側面１２ｃに重ね合わされた状態とする。 After the heat insulating plates 22a and 22b are overlapped with the side surfaces 12a and 12b, as shown in FIG. 8c, the heat insulating plate 22d is centered on the joint portion with the non-bending portion 24 on the end side on the bottom surface 13 side. It is made to rotate from the state facing the bottom face 13, and it is made the state superimposed on the side surface 12d. Further, the heat insulating plate 22c is rotated from the state facing the bottom surface 13 around the joint portion with the heat insulating plate 23 at the end on the bottom surface 13 side, and is superposed on the side surface 12c.
　断熱板２２ｃ，２２ｄがそれぞれ側面１２ｃ，１２ｄに重ね合わされた状態となると、断熱板２２ｃ，２２ｄの幅がそれぞれ、側面１２ｃ，１２ｄの幅から断熱板２２ａ，２２ｂの厚さを減じた幅となっているため、図８ｄに示すように、断熱板２２ｃ，２２ｄの両端部が断熱板２２ａ，２２ｂと当接した状態となる。それにより、断熱板２２ａ～２２ｄが側面１２ａ～１２ｄに重ね合わされた状態に保持されることとなる。 When the heat insulating plates 22c and 22d are overlaid on the side surfaces 12c and 12d, the width of the heat insulating plates 22c and 22d is the width obtained by subtracting the thickness of the heat insulating plates 22a and 22b from the width of the side surfaces 12c and 12d, respectively. Therefore, as shown in FIG. 8d, both end portions of the heat insulating plates 22c and 22d are in contact with the heat insulating plates 22a and 22b. As a result, the heat insulating plates 22a to 22d are held in a state of being superimposed on the side surfaces 12a to 12d.
　このようにして保冷箱１が組み立てられることになるが、側面１２ａ，１２ｂが上記のような構成を有して折り畳まれているため、収納容器の上端部を上方に引き上げるようにして側面を伸ばした後、４つの断熱板２２ａ～２２ｄを、収納容器の底面１３に対向した状態から側面１２ａ～１２ｄに重ね合わされる状態にそれぞれ回動させることで、素早く容易に組み立てることができ、断熱板を有する構成においても素早く容易に組み立てることができる。 The cold box 1 is assembled in this way, but the side surfaces 12a and 12b are folded with the above-described configuration, so that the side surfaces are extended by pulling the upper end of the storage container upward. After that, by rotating the four heat insulating plates 22a to 22d from the state facing the bottom surface 13 of the storage container to the state where they are superimposed on the side surfaces 12a to 12d, the heat insulating plates can be assembled quickly and easily. Even in the configuration having it, it can be assembled quickly and easily.
　なお、本形態においては、等脚台形領域１４ａ，１４ｂが２枚のアルミシートが重ね合わされて構成されるとともに、等脚台形領域１４ａ，１４ｂの境界部分にステッチ１５が形成されており、また、三角領域１６ａ，１６ｂが１枚のアルミシートから構成されていることにより、等脚台形領域１４ａ，１４ｂからなる領域が、等脚台形領域１４ａ，１４ｂの脚と側面１２ａ，１２ｂの側面１２ｃ，１２ｄとの連接辺とで囲まれた三角領域１６ａ，１６ｂよりも硬く、かつ、等脚台形領域１４ａ，１４ｂの境界部分にて折り畳み可能に構成されているが、等脚台形領域１４ａ，１４ｂと三角領域１６ａ，１６ｂとの材質や厚さを異ならせることで、等脚台形領域１４ａ，１４ｂが三角領域１６ａ，１６ｂよりも硬くなる構成としてもよい。 In this embodiment, the isosceles trapezoidal regions 14a and 14b are configured by overlapping two aluminum sheets, and stitches 15 are formed at the boundary portions of the isosceles trapezoidal regions 14a and 14b. Since the triangular regions 16a and 16b are made of a single aluminum sheet, the regions formed of the isosceles trapezoidal regions 14a and 14b are the legs of the isosceles trapezoidal regions 14a and 14b and the side surfaces 12c and 12d of the side surfaces 12a and 12b. It is harder than the triangular areas 16a and 16b surrounded by the connecting side and the foldable area at the boundary between the isosceles trapezoidal areas 14a and 14b. The isosceles trapezoidal regions 14a and 14b may be harder than the triangular regions 16a and 16b by making the materials and thicknesses of the regions 16a and 16b different.
　また、収納容器の天面が、２つの蓋部１１ａ，１１ｂによって開閉自在に構成されているが、側面１２ａ～１２ｄのうち１つの側面と連接した１つの蓋部によって開閉自在に構成されていてもよい。また、蓋部が取り外し可能なものであってもよい。 The top surface of the storage container is configured to be opened and closed by two lid portions 11a and 11b, but is configured to be freely opened and closed by one lid portion connected to one of the side surfaces 12a to 12d. Also good. Further, the lid may be removable.
　また、蓋部１１ａ，１１ｂ及び底面１３は、可撓性を有さないシートから構成されていてもよい。 Further, the lid portions 11a and 11b and the bottom surface 13 may be made of a sheet having no flexibility.
　さらに、収納容器の形状は、直方体ではなく立方体であってもよい。ただし、収納容器の形状が立方体である場合は、上述した断熱板２２ａ，２２ｂについても、底面１３に対向する状態とされた場合にその一部が重なり合うものとなるため、非折り曲げ部２５の高さを互いに異ならせる必要がある。 Furthermore, the shape of the storage container may be a cube instead of a rectangular parallelepiped. However, when the shape of the storage container is a cube, the above-described heat insulating plates 22a and 22b also overlap when part of the heat insulating plates 22a and 22b is opposed to the bottom surface 13; It is necessary to make them different from each other.
　（他の実施の形態）
　図９ａは、本発明の保冷箱の他の実施の形態における天面が開かれた状態の外観斜視図である。図９ｂは、図９ａに示した保冷箱１０１の天面が閉じられた状態の外観斜視図である。図９ｃは、図９ａに示した保冷箱１０１が折り畳まれた状態の外観斜視図である。 (Other embodiments)
FIG. 9a is an external perspective view of a state in which the top surface is opened in another embodiment of the cold box of the present invention. FIG. 9B is an external perspective view showing a state where the top surface of the cold box 101 shown in FIG. 9A is closed. FIG. 9c is an external perspective view of the cold insulation box 101 shown in FIG. 9a in a folded state.
　本形態は図９ａ～図９ｃに示すように、図１ａ～図１ｃ、図２ａ、図２ｂ、図３ａ及び図３ｂに示したものに対して、蓋部１１１ａ，１１１ｂの側面１１２ｃ，１１２ｄとの連接方向の長さが大きく異なり、それにより、蓋部１１１ａ，１１１ｂに取り付けられた断熱板１２１ａ，１２１ｂの形状が互いに異なっている点が異なるものである。これは、本形態の保冷箱１０１においては、蓋部１１１ａの側面１２１ｃとの連接方向の長さを、側面１１２ｃの高さと同等としていることで、蓋部１１１ａの長さが、蓋部１１１ｂの長さよりも、蓋部１１１ａ，１１１ｂが閉じられた際に蓋部１１１ｂに重なり合う領域の幅以上に長くなっていることによるものである。 As shown in FIGS. 9a to 9c, the present embodiment is different from those shown in FIGS. 1a to 1c, 2a, 2b, 3a and 3b with respect to the side surfaces 112c and 112d of the lid portions 111a and 111b. The length in the connecting direction is greatly different, which is different in that the shapes of the heat insulating plates 121a and 121b attached to the lid portions 111a and 111b are different from each other. This is because, in the cold box 101 of this embodiment, the length in the direction of connection with the side surface 121c of the lid portion 111a is equal to the height of the side surface 112c, so that the length of the lid portion 111a is equal to the height of the lid portion 111b. This is because the length is longer than the width of the region overlapping the lid 111b when the lids 111a and 111b are closed.
　以下に、上記のように構成された保冷箱１０１による特有の効果について説明する。 Hereinafter, a specific effect of the cold box 101 configured as described above will be described.
　図１０は、図９ａ～図９ｃに示した保冷箱１０１において断熱板１２２ａ～１２２ｄがそれぞれ底面１１３に対向する状態に倒された状態を示す断面図である。 FIG. 10 is a cross-sectional view showing a state in which the heat insulating plates 122a to 122d are brought down to face the bottom surface 113 in the cold box 101 shown in FIGS. 9a to 9c.
　断熱板１２２ａ～１２２ｄが全て倒されて底面１１３に対向している状態においては、側面１１２ａ～１１２ｄがアルミシートから構成されていることで側面１１２ａ～１１２ｄの自立性がなくなっている。しかし、蓋部１１１ａの側面１２１ｃとの連接方向の長さが、側面１１２ｃの高さと同等となっており、蓋部１１１ａにはその略全面に断熱板１２１ａが取り付けられているため、図１０に示すように、側面１１２ｃが起立した状態となる。それにより、保冷箱１０１を組み立てる際に、底面１１３と対向した状態となっている断熱板１２２ａ，１２２ｂを側面１１２ａ，１１２ｂに重ね合わされる状態まで回動させやすくなる。 In the state where the heat insulating plates 122a to 122d are all turned down and face the bottom surface 113, the side surfaces 112a to 112d are made of an aluminum sheet, so that the side surfaces 112a to 112d are not self-supporting. However, since the length in the connecting direction of the lid portion 111a with the side surface 121c is equal to the height of the side surface 112c, and the heat insulating plate 121a is attached to almost the entire surface of the lid portion 111a, FIG. As shown, the side surface 112c is upright. Thereby, when the cold box 101 is assembled, the heat insulating plates 122a and 122b facing the bottom surface 113 can be easily rotated to a state where they are superimposed on the side surfaces 112a and 112b.
　なお、蓋部１１１ａの断熱板１２１ａが取り付けられていない領域においては、一定の強度を保持するために２枚のアルミシート間に、ポリプロピレンからなる１ｍｍ厚の樹脂シートが介在しているため、この樹脂シートによっても側面１１２ｃが支えられることとなるが、断熱板１２１ａが蓋部１１１ａの略全面に取り付けられていることにより、蓋部１１１ａの断熱板１２１ａが取り付けられていない領域に樹脂シートが介在していなくても、側面１１２ｃが起立した状態が保持される。なお、蓋部１１１ａの周縁部にステッチ（不図示）を形成することによっても、蓋部１１１ａの断熱板１２１ａが取り付けられていない領域の強度を高めることができる。 In the region where the heat insulating plate 121a of the lid portion 111a is not attached, a 1 mm thick resin sheet made of polypropylene is interposed between the two aluminum sheets in order to maintain a certain strength. The side surface 112c is also supported by the resin sheet. However, since the heat insulating plate 121a is attached to substantially the entire surface of the lid portion 111a, the resin sheet is interposed in the region where the heat insulating plate 121a of the lid portion 111a is not attached. Even if not, the state where the side surface 112c stands is maintained. In addition, the intensity | strength of the area | region where the heat insulation board 121a of the cover part 111a is not attached can also be raised also by forming a stitch (not shown) in the peripheral part of the cover part 111a.
　図１１ａは、本発明の保冷箱の他の実施の形態における天面が開かれた状態の外観斜視図である。図１１ｂは、図１１ａに示した保冷箱２０１の天面が閉じられた状態の外観斜視図である。図１１ｃは、図１１ａに示した保冷箱２０１が折り畳まれた状態を示す外観図である。 FIG. 11a is an external perspective view showing a state in which the top surface is opened according to another embodiment of the cold box of the present invention. FIG. 11B is an external perspective view showing a state where the top surface of the cold box 201 shown in FIG. 11A is closed. FIG. 11C is an external view showing a state where the cold box 201 shown in FIG. 11A is folded.
　本形態は図１１ａ～図１１ｃに示すように、図１ａ～図１ｃ、図２ａ、図２ｂ、図３ａ及び図３ｂに示したものに対して、側面２１２ｄ及びそれに対向する側面（図１１ａ～図１１ｃには表れていない）、並びに側面２１２ａ及びそれに対向する側面（図１１ａ～図１１ｃには表れていない）の構成が異なるものである。 In this embodiment, as shown in FIGS. 11a to 11c, the side surface 212d and the side surface opposite to that shown in FIGS. 1a to 1c, 2a, 2b, 3a and 3b (see FIGS. 11c), and the side surface 212a and the opposite side surface (not shown in FIGS. 11a to 11c) have different configurations.
　本形態における側面２１２ｄ及びそれに対向する側面はそれぞれ、蓋部１１ａ，１１ｂ側の上側領域２１７ａと、底面側の下側領域２１７ｂとからなる。上側領域２１７ａは、１枚のアルミシートの保冷箱２０１の内側の面に生地（布）が重ね合わされて構成されている。下側領域２１７ｂは、１枚のアルミシートから構成されている。それにより、上側領域２１７ａが下側領域２１７ｂよりも硬くなっている。これら上側領域２１７ａと下側領域２１７ｂとの境界には、ステッチ２１８が形成されている。ステッチ２１８は、等脚台形領域１４ａ，１４ｂの第２の辺と同じ高さにおいて、側面２１２ｄ及びそれに対向する側面と蓋部１１ｂ，１１ａとの境界にそれぞれ並行して延びている。 The side surface 212d and the side surface opposite to the side surface 212d in this embodiment are each composed of an upper region 217a on the lid portions 11a and 11b side and a lower region 217b on the bottom surface side. The upper region 217a is configured by overlapping fabric (cloth) on the inner surface of a single aluminum sheet cold box 201. The lower region 217b is composed of a single aluminum sheet. Accordingly, the upper region 217a is harder than the lower region 217b. A stitch 218 is formed at the boundary between the upper region 217a and the lower region 217b. The stitch 218 extends in parallel to the side surface 212d and the boundary between the side surface facing the side surface 212d and the lid portions 11b and 11a at the same height as the second sides of the isosceles trapezoidal regions 14a and 14b.
　また、本形態における側面２１２ａ及びそれに対向する側面はそれぞれ、三角領域１６ａ，１６ｂのそれぞれに、側面２１２ｄ及びそれに対向する側面に形成されたステッチ２１８から延びたステッチ２１９が形成されている。 In addition, the side surface 212a and the side surface opposite to the side surface 212a in this embodiment are respectively formed with stitches 219 extending from the side surface 212d and the stitch 218 formed on the side surface facing the side surface 212d.
　上記のように構成された保冷箱２０１においても、図１ａ～図１ｃ、図２ａ、図２ｂ、図３ａ及び図３ｂに示したものと同様にして折り畳まれたり、組み立てられたりする。その際、側面２１２ｄ及びそれに対向する側面においては、上側領域２１７ａと下側領域２１７ｂとの境界にステッチ２１８が形成されていることにより、上側領域２１７ａと下側領域２１７ｂとの境界部分が折り畳まれやすくなっている。また、側面２１２ａ及びそれに対向する側面においても、三角領域１６ａ，１６ｂが、ステッチ２１９を介して折り畳まれやすくなっている。さらに、上側領域２１７ａが下側領域２１７ｂよりも硬くなっていることにより、上側領域２１７ａが伸長した状態が維持されたまま保冷箱２０１が折り畳まれることになり、側面２１２ｄ及びそれに対向する側面がくしゃくしゃになりにくくなる。 The cold box 201 configured as described above is also folded or assembled in the same manner as shown in FIGS. 1a to 1c, 2a, 2b, 3a, and 3b. At that time, the stitches 218 are formed at the boundary between the upper region 217a and the lower region 217b on the side surface 212d and the side surface opposite thereto, so that the boundary portion between the upper region 217a and the lower region 217b is folded. It has become easier. Further, the triangular regions 16 a and 16 b are also easily folded via the stitch 219 on the side surface 212 a and the side surface opposite to the side surface 212 a. Further, since the upper region 217a is harder than the lower region 217b, the cold insulation box 201 is folded while the upper region 217a is maintained in an extended state, and the side surface 212d and the side surface facing the side surface 212d are crumpled. It becomes difficult to become.
　なお、図１ａ～図１ｃ及び図９ａ～図９ｃに示した保冷箱１，１０１においても、側面１２ａ，１１２ａ及びそれに対向する側面の三角領域１６ａ，１６ｂ，１１６ａ，１１６ｂのそれぞれに、図１１ａ～図１１ｃに示したステッチ２１９と同様のステッチが形成されていてもよい。 In the cold box 1 101 shown in FIGS. 1a to 1c and 9a to 9c, the side surfaces 12a and 112a and the triangular regions 16a, 16b, 116a, and 116b on the side surfaces facing the side surfaces 12a and 112a are respectively shown in FIGS. Stitches similar to the stitches 219 shown in FIG. 11c may be formed.
