Description

Cold box

The present invention relates to a cold storage box for accommodating articles and keeping them cold, and more particularly to a collapsible cold storage box.

Among the logistics systems, both land and air transport provide services at fixed temperatures, such as at low temperatures. In the case of conveying the article at a low temperature, for example, the article and the cold-preserving material may be housed together in a heat-insulating cold storage box, and the article may be cooled while being cooled by the cold air of the cold-preserving material. Further, in the case where the article is stored at a low temperature in a warehouse, the article and the cold-preserving material can be housed together in a heat-insulating cold storage box, and the article can be kept cold while being cooled by the cold air of the cold-preserving material.

In the case of the cold box, it is considered that the outer casing is arranged such that the plate-shaped heat insulating material is superposed on the inner wall of the outer casing (see, for example, Patent Document 1). As described above, the cold-insulation box in which the plate-shaped heat insulating plates are disposed in the outer container, that is, the storage container, can be used, so that the articles can be kept cold without using the heat-insulating case.

Japanese Patent Laid-Open Publication No. 2003-182777

[Problems to be Solved by the Invention] In recent years, as described above, the cold storage box is often used to transport articles at a low temperature. Therefore, in the case of conveying an article at a low temperature, it is also sought to be close to the ease of handling in the case of conveying the article at a normal temperature. As an example, the cold storage box needs to be quickly and easily folded and assembled in the same manner as the storage device used for conveying articles at normal temperature.

However, as described above, in the case where the cold storage box in which the plate-shaped heat insulating material is disposed in the storage container is folded, for example, the heat insulating material is taken out from the storage container to fold the storage container. Therefore, it cannot be folded and assembled quickly and easily. Then, it is considered that the storage container is constituted by a flexible sheet, and the storage container is folded in a state in which the plate-shaped heat insulating material is disposed in the storage container. However, in this case, since the storage container is flexible, it is not easy to fold and fold at the time of folding, and it is easy to wrinkle, and it is laborious to fold and assemble, and it is difficult to fold and assemble quickly and easily. Moreover, when the storage container is flexible, it is difficult to assemble the plate-shaped heat insulating material disposed in the storage container, and therefore it is difficult to fold and assemble quickly and easily.

The present invention has been made in view of the problems of the prior art described above, and an object thereof is to provide a cold-insulation box which can be quickly and easily folded and assembled under a configuration in which a heat insulating plate is disposed in a storage container. [The way to solve the problem]

In order to achieve the above object, the present invention has a rectangular parallelepiped or a cubic storage container, the top surface of which is configured to be freely opened and closed, and at least the side surface is formed of a flexible member, and four heat insulating plates which are arranged to be superposed and superimposed on the storage. The inner side of the four side faces of the container is configured to be rotatable from the state of the inner side of the side surface to the state of the bottom surface, centering on the end side of the bottom surface side of the storage container. Each of the four side faces facing each other has a region consisting of two slightly isosceles trapezoids, and the first and second sides of the side faces are respectively formed as a first side, and the first side is There is a second side, and the first side is longer than the second side. And the area is configured to be harder than the area surrounded by the "two waists of the first isosceles trapezoid" and the "connecting side of the side and the other side" in the outer side of the area, and the second side can be fold.

As described above, in the present invention, one of the four side faces of the storage container facing each other is configured such that "the area along the upper and lower end sides along the side faces thereof is respectively the first side, at the first The second side, the first side is longer than the second side, and the two sides are slightly isosceles trapezoidal, and the two sides of the outer side of the area are "two slightly isosceles trapezoidal waist" and "the side and The area around which the connecting side of the other side is surrounded is harder and foldable on the second side. Therefore, when the four heat insulating plates are respectively rotated from the state of being stacked on the side surface of the storage container made of the flexible member to the state facing the bottom surface, when the upper end portion of the storage container is pushed downward, the storage is carried out. Among the four side faces of the four sides of the container, the area formed by the two isosceles trapezoids is folded so that the portion forming the second side becomes the apex and protrudes toward the inner side of the storage container, and is folded along Folded by the shape of the area consisting of two slightly isosceles trapezoids; and the area surrounded by the "two waists of the isosceles trapezoid" and the "connecting sides of the sides and other sides" are sandwiched by a slightly isosceles trapezoid The two areas that make up the fold. Further, a plurality of side faces are folded as described above, whereby the other side faces are folded in the central portion in the height direction so as to be sandwiched by the vicinity of the connecting portion of the one set of the side faces in two regions constituted by the slightly isosceles trapezoidal shape. Thereby, the storage container is folded into a predetermined shape without wrinkles, and the cold storage box is collapsed and folded. Further, in this case, since the region composed of the two slightly isosceles trapezoids is hard, the side surface of the storage container is likely to be slightly stretched, whereby the heat insulating plate is easily rotated. Further, as described above, in the case where the folded cold box is assembled, the upper end portion of the storage container is pulled upward to extend the side surface, and then the four heat insulating plates are respectively rotated from the state toward the bottom surface to the overlap. In the state of the side.

As described above, as long as the four heat insulating plates are rotated and the upper end portion of the storage container is pushed downward, the storage container is folded into a predetermined shape without wrinkles, and the area composed of two slightly isosceles trapezoids is hard. The side of the storage container is likely to be slightly stretched. Thereby, the cold storage box can be folded and assembled quickly and easily. [Effects of the Invention]

In the present invention, one of the four side faces of the storage container facing each other is configured such that "the upper and lower end sides of the side faces respectively serve as the first side, and the first side has the second side, The area where the first side is longer than the second side and the two isosceles trapezoidal is surrounded by the "two slightly isosceles trapezoidal waist" and the "connecting side of the side and the other side" in the outer side of the area. The area is harder and folds on the second side. Therefore, when the four heat insulating sheets are respectively rotated from the state of being superposed on the side surface of the storage container to the state facing the bottom surface, the upper end portion of the storage container is pressed downward, and the storage container is folded into a predetermined shape without wrinkles. Further, after the upper end portion of the storage container is pulled upward and the side surface is extended, the four heat insulating plates are respectively rotated from the state toward the bottom surface to the state of being superposed on the side surface, thereby assembling the cold insulation box. As described above, in the configuration in which the heat insulating plate is disposed in the storage container, it can be quickly and easily folded and assembled. Further, since the area composed of the two slightly isosceles trapezoids is hard, the side surface of the storage container is likely to be slightly stretched when the cold storage box is assembled. Thereby, the heat insulating plate can be easily rotated, and the cold storage box can be assembled quickly and easily.

In the present embodiment, as shown in FIGS. 1a to 1c, 2a, 2b, 3a, and 3b, a rectangular parallelepiped storage container including the lid portions 11a and 11b, the side surfaces 12a to 12d, and the bottom surface 13 is disposed inside the storage container. The heat insulating plates 21a, 21b, 22a to 22d, and 23 are formed.

The lid portions 11a and 11b are formed by laminating two flexible aluminum sheets. The lid portion 11a is connected to the end side of the top surface side of the side surface 12c. Further, the lid portion 11b is connected to the end side on the top surface side of the side surface 12d facing the side surface 12c. Further, the lid portions 11a and 11b are respectively rotated about the side where they are connected to the side surfaces 12c and 12d, whereby the top surface of the storage container is freely opened and closed. Therefore, among the lid portions 11a and 11b, the length in the direction in which the side faces 12c and 12d are connected is a length in which the lid portions 11a and 11b are partially overlapped in the case of closing.

The lid portions 11a and 11b are respectively provided with heat insulating plates 21a and 21b having the same shape as each other on the inner surface of the storage container. Among the heat insulating plates 21a, the entire surface of the surface of the lid portion 11a is not covered with an aluminum foil. When the lid portions 11a and 11b are closed, the heat insulating plate 21a is attached to the innermost surface of the heat insulating plates 22a and 22b so as not to interfere with the thickness of the heat insulating plates 22a and 22b from the peripheral edge portion of the lid portion 11a. : heat insulating plates 22a to 22c superposed on the side faces 12a to 12c; and a lid portion 11b. Among the heat insulating plates 21b, the entire surface of the surface of the lid portion 11b is not covered with an aluminum foil. In the case where the lid portion 11b is closed, the heat insulating plate 21b is mounted on the substantially entire surface so as not to interfere with the heat insulating plates 22a, 22b, and 22d stacked on the side faces 12a, 12b, and 12d, avoiding the area along the lower side. a connecting side of the cover portion 11b to the side surface 12d; and a side to which the connecting side is joined. Thereby, the lengths of the cover portions 11a and 11b and the side faces 12c and 12d in the connection direction are as follows: the cover portion 11a is longer than the cover portion 11b by the "size of the region overlapping each other".

Among the lid portions 11a, in the surface on the inner side of the storage container, the fastening tape 31 is attached to the lid portion 11b in a region where the lid portions 11a and 11b are closed. Further, among the lid portions 11b, in the surface of the outer side of the storage container, when the lid portions 11a and 11b are closed, a fastening tape (not shown) is attached to the lid portion 11a. Further, among the lid portions 11a and 11b, a fastening tape (not shown) is attached to each of the surfaces of the outer surface of the storage container which are "the side that is joined to the side of the side surfaces 12c and 12d." Further, in a region where the heat insulating plates 21a and 21b are not mounted, the cover portions 11a and 11b are respectively provided with a resin sheet (not shown) made of polypropylene and having a thickness of 1 mm between the two aluminum sheets to maintain the fixing strength. Further, a handle 29 for easily opening the lid portion 11a is attached between the lid portion 11a and the fastening tape 31.

The bottom surface 13 is formed of a flexible sheet. Among the bottom surface 13, a heat insulating plate 23 is attached to the inner surface of the storage container, and the entire surface of the bottom surface 13 is not covered with an aluminum foil. Further, the bottom surface 13 serves as a surface on the outer side of the storage container, and the belt body 28 is attached to the side adjacent to the side surface of the side surfaces 12a and 12b. One end of the belt body 28 is attached to the bottom surface 13, and one side of the other end is fitted with a fastening tape 33.

The side faces 12a and 12b are disposed to face each other, and are formed by laminating two flexible aluminum sheets except for a part of the region. The following area is formed by laminating two aluminum sheets: "the area along the end side of the top side 12a, 12b" is the first side of the isosceles trapezoidal area 14a; the bottom surface of the side surfaces 12a, 12b The region having a predetermined width from the end side of the 13 side; and the "side of the region having the predetermined width opposite to the bottom surface 13" is the first side of the isosceles trapezoidal region 14b. Further, among the isosceles trapezoidal regions 14a, 14b, the first side has a second side, and the first side is longer than the second side. Further, the triangular regions 16a and 16b surrounded by the "waist of the isosceles trapezoidal regions 14a and 14b" and the "connecting sides of the side faces 12a and 12b to the side faces 12c and 12d" are composed of an aluminum foil. Among the isosceles trapezoidal regions 14a and 14b in which two aluminum sheets are laminated, a trace 15 is formed around the isosceles trapezoidal regions 14a and 14b. Thereby, the boundary portion with the triangular regions 16a and 16b and the boundary portions of the isosceles trapezoidal regions 14a and 14b are easily folded. Thereby, each of the side faces 12a and 12b facing each other is configured such that "the area along the upper and lower end sides along the side faces 12a, 12b is the first side, and the second side is shared between the first side. The area formed by the two isosceles trapezoidal regions 14a and 14b which are longer than the second side, the waist of the isosceles trapezoidal regions 14a and 14b and the side faces 12a and 12b in the outer side of the isosceles trapezoidal regions 14a and 14b. The area surrounded by the connecting side of the side faces 12c, 12d is harder and foldable on the second side. Further, a fastening tape 32 is attached to a surface of the isosceles trapezoidal region 14a which is the outer side of the storage container. The side surfaces 12a and 12b are provided with heat insulating plates 22a and 22b so as to overlap the surface which becomes the inner side of the storage container. Further, the end portions on the top surface side of the storage container in the side surfaces 12a and 12b are respectively connected to the flap portions 51a and 51b.

Among the flap portions 51a and 51b, when the flap portions 51a and 51b are folded, the inner surface of the container is formed, and the fastening tape 36 is attached along the side of the side surface 12a and 12b. Further, in the flap portions 51a and 51b, when the flap portions 51a and 51b are folded, the center portion in the longitudinal direction of the flap portions 51a and 51b on the outer surface of the storage container is attached with the fastening tape 35. .

Among the heat insulating plates 22a and 22b, the entire surface thereof is covered with an aluminum foil and has a width equivalent to that of the side faces 12a and 12b. The heat insulating plates 22a and 22b have a height from the height of the side faces 12a and 12b minus the thickness at which the heat insulating plate 23 and the heat insulating plates 22c and 22d described later are superposed. The heat insulating plates 22a and 22b are erected on the non-folded portions 25 to which the end faces of the heat insulating plates 23 are erected, and are superimposed on the side faces 12a and 12b, and overlapped with the non-curved portions 25. The side faces 12a and 12b are opposite sides, and are joined to the non-curved portion 25 by sewing or the like. Thereby, each of the heat insulating plates 22a and 22b is configured to be able to freely rotate from the state of being overlapped on the side faces 12a and 12b to the state of the bottom face 13 centering on the end side on the bottom face 13 side.

The height of the non-curved portion 25 is equal to the thickness at which the heat insulating plates 22c and 22d are superposed. Thereby, when the heat insulating plates 22c and 22d are set to face the bottom surface 13, and the heat insulating plates 22a and 22b are set to face the bottom surface 13, the heat insulating plates 22a and 22b are as shown in Fig. 2b. The upward facing surface is approximately parallel to the bottom surface 13. Further, it is considered that the non-buckling portion 25 is made of the same material as the heat insulating plates 22a and 22b, but the non-bending portion 25 does not constitute the heat insulating plate in the present invention.

The side faces 12c and 12d are disposed to face each other, and are formed by laminating two flexible aluminum sheets. The side surfaces 12c and 12d are provided with heat insulating plates 22c and 22d so as to be superposed on the inner surface of the storage container.

Among the heat insulating plates 22c and 22d, the entire surface thereof is covered with an aluminum foil and has a width from which the thickness of the heat insulating plates 22a and 22b is subtracted from the width of the side faces 12c and 12d. The heat insulating plate 22c has a height from which the thickness of the heat insulating plate 23 is subtracted from the height of the side surface 12c. The heat insulating plate 22c is superposed on the side surface 12c in a state of being erected on the end side of the heat insulating plate 23, and the side opposite to the side surface 12c of the abutting surface of the heat insulating plate 23 is joined by sewing or the like. To the insulation board 23. Thereby, the heat insulating plate 22c is configured to be freely rotatable from the state of being overlapped on the side surface 12c to the state of facing the bottom surface 13 at the center of the end side on the bottom surface 13 side. The heat insulating plate 22d has a height from which the thickness of the heat insulating plate 22c and the heat insulating plate 23 is subtracted from the height of the side surface 12d. The heat insulating plate 22d is superposed on the side surface 12d with the non-buckling portion 24 attached to the end side of the heat insulating plate 23 erected, and "the side opposite to the side surface 12d of the abutting surface of the non-buckling portion 24" The side is joined to the non-curved portion 24 by sewing or the like. Thereby, the heat insulating plate 22d is configured to be freely rotatable from the state of being overlapped on the side surface 12d to the state facing the bottom surface 13 at the center of the end side on the bottom surface 13 side. Further, it is considered that the non-bending portion 24 is made of the same material as the heat insulating plate 22d, but the non-buckling portion 24 does not constitute the heat insulating plate in the present invention.

The heat insulating plates 22c, 22d have a height at which a part overlaps each other when they are respectively set to face the bottom surface 13. Therefore, the height of the non-bending portion 24 is equal to the thickness of the heat insulating plate 22c, and after the heat insulating plate 22c is set to face the bottom surface 13, the heat insulating plate 22d is set to face the bottom surface 13 again. At this time, as shown in Fig. 3b, the upwardly facing surface of the heat insulating plate 22d is in a state in which the bottom surface 13 is approximately parallel.

Hereinafter, a method of using the cold box 1 having the above configuration will be described.

First, a folding method of the cold box 1 will be described.

4a to 4d are external perspective views for explaining a folding method of the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b.

In the case where the cold-insulation box 1 shown in FIGS. 1a to 1c, 2a, 2b, 3a, and 3b is folded, first, as shown in FIG. 4a, in the cover portions 11a, 11b and the flap portion 51a. When the 51b is in the open state, the heat insulating plates 22c and 22d are lowered.

5a to 5c are cross-sectional views for explaining the effects of placing the heat insulating plates 22c and 22d in the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b.

In the case where the heat insulating plates 22c, 22d are placed in the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b, first, as shown in Fig. 5a, the heat insulating plate 22C is bottomed. The end portion of the 13 side is centered on the joint portion with the heat insulating plate 23, and is rotated from the state of being superposed on the side surface 12c, and is placed in contact with the heat insulating plate 23 to be placed on the heat insulating plate 23. Thereby, the heat insulating plate 22c is in a state of facing the bottom surface 13.

Then, as shown in Fig. 5b, the heat insulating plate 22d is rotated from the side where the end side of the bottom surface 13 side and the non-buckling portion 24 are centered, and is superposed on the side surface 12d. In this way, as described above, the heat insulating plates 22c, 22d have a height at which a part thereof overlaps with each other in a state of being oriented toward the bottom surface 13, respectively, so that the heat insulating plate 22d is non-flexed as shown in Fig. 5c. The joint portion of the portion 24 is a side portion on the opposite side, and is in contact with the heat insulating plate 22c and facing the bottom surface 13. At this time, since the height of the non-bending portion 24 is equal to the thickness of the heat insulating plate 22c, the upward facing surface of the heat insulating plate 22d is approximately parallel to the bottom surface 13.

As described above, after the heat insulating plates 22c and 22d are placed down and set to face the bottom surface 13, the heat insulating plates 22a and 22b are lowered as shown in Fig. 4b.

6a and 6b are cross-sectional views for explaining the effect of placing the heat insulating plates 22a and 22b in the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b.

In the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b, the heat insulating plates 22c and 22d are placed in a state of being opposed to the bottom surface 13 as described above, and then placed down. In the case of the heat insulating plates 22a and 22b, the heat insulating plates 22a and 22b can be simultaneously lowered as shown in Fig. 6a for the following reasons: the heat insulating plates 22a and 22b are disposed in a state of being oriented toward the bottom surface 13, respectively. The height that does not overlap each other.

Further, as described above, the heat insulating plate 23 to which the bottom surface 13 is attached is in a state in which a part of the heat insulating plates 22c and 22d which are placed in a stacked state is placed, and as shown in FIG. 6b, the heat insulating plate 22c is in a state of the following state: In the upper and lower heat insulating plates 22d of 22d, the heat insulating plates 22a and 22b are placed thereon. In this case, as described above, the height of the non-bending portion 25 is equal to the thickness at which the heat insulating plates 22c and 22d are overlapped. Therefore, in the state where the heat insulating plates 22a and 22b are fallen down toward the bottom surface 13, the heat insulating plates 22a and 22b are The upward facing surface is approximately parallel to the bottom surface 13.

As described above, when all of the heat insulating plates 22a to 22d are fallen and are oriented toward the bottom surface 13, the side faces 12a to 12d are made of an aluminum foil, and the self-supporting properties of the side faces 12a to 12d are lost, when the upper end of the storage container is to be closed. When the portion is pushed downward, as shown in Fig. 4c, the storage container can be folded.

Here, the effect of folding the side surfaces 12a to 12d of the storage container will be described.

7a to 7c are views for explaining the effects of folding the side surfaces 12a to 12d of the cold storage box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b into the storage container, and are The cold storage tank 1 is observed on the top side.

1A to 1c, 2a, 2b, 3a, and 3b, the cold storage box 1 is as described above, and one of the four side faces 12a and 12b of the four sides of the storage container is configured to be The two isosceles trapezoidal regions 14a, 14b are formed along the upper and lower end sides of the side faces 12a, 12b as the first side, the second side sharing the first side, and the first side being longer than the second side. The area is harder than the triangular regions 16a, 16b surrounded by the "two isosceles trapezoidal waists" and the "connecting sides of the side faces 12a, 12b to the side faces 12c, 12d" in the outer sides of the isosceles trapezoidal regions 14a, 14b. And can be folded on the second side. Therefore, among the side faces 12a and 12b, when the upper end portion of the container is pushed downward from the unfolded state as shown in Fig. 7a, the two isosceles trapezoidal regions 14a, 14b are formed as shown in Fig. 7b. The second side portion is apexed and protrudes toward the inside of the storage container, and the side faces 12a, 12b are folded along the outer shape of the two isosceles trapezoidal regions 14a, 14b, "two slightly isosceles trapezoidal waists The triangular regions 16a and 16b surrounded by the "connecting sides of the side faces 12a, 12b and the side faces 12c, 12d" are folded so as to be sandwiched by the isosceles trapezoidal regions 14a, 14b.

Further, the side faces 12a, 12b are folded as described above, whereby as shown in Fig. 7c, the side faces 12c, 12d are folded to be folded in the lateral direction, and the vicinity of the joint portion with the side faces 12a, 12b is sandwiched in the isosceles trapezoidal region 14a, 14b.

After folding the side faces 12a to 12d as described above, as shown in Fig. 4d, the lid portion 11a is closed after closing the lid portion 11b. Further, the fastening tape 31 of the lid portion 11a is joined to the fastening tape of the lid portion 11b. Further, the flap portions 51a and 51b are folded so that the fastening tapes 36 of the flap portions 51a and 51b are joined to the fastening tapes of the lid portions 11a and 11b. Further, the belt body 28 attached to the bottom surface 13 is joined to the side surface 12a, 12b of the cold box 1 to be bonded to the fastening tape 33 of the belt body 28 and the fastening tape 35 of the flap portions 51a, 51b, and the cold box 1 is placed. Set to collapse.

Since the cold-insulation box 1 is folded as described above, and since the side faces 12a and 12b have the above-described configuration, the four heat insulating plates 22a to 22d are respectively rotated from the state of being superposed on the side faces 12a to 12d of the container to the bottom face 13 After that, the upper end portion of the storage container is pushed downward, so that the storage container is folded into a predetermined shape without wrinkles. Thereby, even the structure having the heat insulating plate can be folded quickly and easily.

As described above, the cold-retaining box 1 can be easily transported without opening the lid portions 11a and 11b as long as the handle 29 is gripped while the side surface 12d is held on the upper side.

Further, the isosceles trapezoidal regions 14a, 14b may be shaped such that the first side and the second side are not parallel, or the waist portion is not equal to a trapezoidal shape, and the inclusions are defined as a slightly isosceles ladder type.

Next, a method of assembling the cold storage box 1 as described above is said.

8a to 8d are perspective views showing the appearance of a method of assembling the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b14.

In the case of assembling the cold-insulation box 1 as described above, first, as shown in FIG. 8a, the fastening tape 33 of the belt body 28 is peeled off from the fastening tape 35 of the flap portions 51a, 51b, and from the lid portion 11a, The fastening tape of 11b peels off the fastening tape 36 of the flap portions 51a, 51b, and opens the flap portions 51a, 51b. Further, the fastening tape of the lid portion 11b is peeled off from the fastening tape 31 of the lid portion 11a, and the lid portions 11a, 11b are opened.

Further, after the upper end portion of the storage container is pulled upward and the side surface is extended, as shown in FIG. 8b, the heat insulating plates 22a and 22b are respectively centered on the joint portion of the end side on the bottom surface 13 side and the non-curved portion 25. Rotating from the state toward the bottom surface 13 is defined as being superimposed on the side faces 12a, 12b. In this case, the isopic trapezoidal regions 14a and 14b are hard and the side faces 12a and 12b are likely to be approximately stretched, and the heat insulating plates 22a and 22b are easily rotated from the state toward the bottom face 13 to the side faces 12a and 12b.

After the heat insulating plates 22a and 22b are stacked on the side faces 12a and 12b, as shown in FIG. 8c, the heat insulating plate 22d is centered on the joint portion of the end side on the bottom surface 13 side and the non-buckling portion 24, and Rotation from the state toward the bottom surface 13 is defined as a state of being superposed on the side surface 12d. In addition, the heat insulating plate 22c is rotated from the end portion on the bottom surface 13 side to the joint portion of the heat insulating plate 23, and is rotated from the state toward the bottom surface 13, and is superposed on the side surface 12c.

When the heat insulating plates 22c and 22d are superposed on the side faces 12c and 12d, respectively, the widths of the heat insulating plates 22c and 22d are respectively the following widths: the thickness of the heat insulating plates 22a and 22b is subtracted from the width of the side faces 12c and 12d; 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. Thereby, the heat insulating plates 22a to 22d are held in a state of being superposed on the side faces 12a to 12d.

Since the cold storage box 1 is assembled as described above, and since the side surfaces 12a and 12b are folded as described above, the upper end portions of the storage container are pulled upward and the side surfaces are extended, and the four heat insulating plates 22a to 22d can be respectively separated. From the state of being oriented toward the bottom surface 13 of the storage container to the state of being superposed on the side faces 12a to 12d, it is quickly and easily assembled, and the structure having the heat insulating plate is quickly and easily assembled.

Further, in the present embodiment, the isosceles trapezoidal regions 14a and 14b are formed by laminating two aluminum sheets, and the boundary portions of the isosceles trapezoidal regions 14a and 14b are collectively formed with the traces 15 and the triangular regions 16a and 16b. It is composed of an aluminum foil, and the regions formed by the above-described isosceles trapezoidal regions 14a, 14b are formed as follows: "waist of the isosceles trapezoidal regions 14a, 14b" and "sides 12a, 12b and the side faces 12c, 12d" The triangular regions 16a, 16b surrounded by the connecting edges are harder and are foldable at the boundary portions of the isosceles trapezoidal regions 14a, 14b. However, the isosceles trapezoidal regions 14a and 14b may be made different in material or thickness from the triangular regions 16a and 16b, whereby the isosceles trapezoidal regions 14a and 14b may be formed to be harder than the triangular regions 16a and 16b.

Further, the top surface of the storage container is configured to be openable and closable by the two lid portions 11a and 11b. However, the lid portion may be opened and closed by being connected to one of the side surfaces 12a to 12d. Moreover, the cover portion can also be a detachable person.

Further, the lid portions 11a and 11b and the bottom surface 13 may be formed of a sheet having no flexibility.

Further, the shape of the storage container may be a cube without a rectangular parallelepiped. In the case where the shape of the storage container is a cube, the heat insulating plates 22a and 22b are also overlapped in a state of being oriented toward the bottom surface 13, so that the heights of the non-bending portions 25 are different from each other. .

[Other Embodiments] Fig. 9a is an external perspective view showing a state in which a top surface is opened in another embodiment of the cold-insulation container of the present invention. Fig. 9b is an external perspective view showing the state in which the top surface of the cold insulation box 101 shown in Fig. 9a is closed. Fig. 9c is an external perspective view showing the cold box 101 shown in Fig. 9a in a folded state.

This embodiment is shown in FIGS. 9a to 9c, and the connection directions of the cover portions 111a and 111b to the side faces 112c and 112d are shown in comparison with those shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b. The lengths are quite different, whereby the difference between the two is as follows: the shapes of the heat insulating plates 121a, 121b attached to the lid portions 111a, 111b are different from each other. The reason is as follows: In the cold-insulation box 101 of the present embodiment, the length of the lid portion 111a in the direction of connection with the side surface 121c is made equal to the height of the side surface 112c, so that the length of the lid portion 111a is longer than the length of the lid portion 111b. The width of the region where the lid portions 111a and 111b are overlapped in the lid portion 111b is "above".

Hereinafter, the specific effects of the cold storage box 101 configured as described above will be described.

Fig. 10 is a cross-sectional view showing the state in which the heat insulating plates 122a to 122d in the cold-insulation box 101 shown in Figs. 9a to 9c are respectively turned down toward the bottom surface 113.

In a state in which all of the heat insulating plates 122a to 122d are lowered and directed toward the bottom surface 113, the side faces 112a to 112d are made of an aluminum foil, and the self-supporting properties of the side faces 112a to 112d are lost. However, the length of the cover portion 111a in the connection direction with the side surface 121c is equal to the height of the side surface 112c, and the cover portion 111a is attached with the heat insulating plate 121a on the substantially entire surface thereof, so that the side surface 112c is erected as shown in FIG. . As a result, when the cold-insulation box 101 is assembled, it is easy to rotate the heat-insulating plates 122a and 122b which are opposed to the bottom surface 113 to be superposed on the side faces 112a and 112b.

Further, among the regions of the lid portion 111a where the heat insulating plate 121a is not attached, a 1 mm thick resin sheet made of polypropylene is interposed between the two aluminum sheets to maintain the fixing strength, and thus the resin sheet is supported thereby. Side 112c. However, by attaching the heat insulating plate 121a to the substantially entire surface of the lid portion 111a, even if the resin sheet is not interposed in the region where the heat insulating plate 121a is not attached to the lid portion 111a, the side surface 112c is kept in the upright state. Further, by forming a trace (not shown) on the peripheral portion of the lid portion 111a, the strength of the region of the lid portion 111a where the heat insulating plate 121a is not attached can be lifted.

Fig. 11a is an external perspective view showing a state in which the top surface is opened in another embodiment of the cold box of the present invention. Fig. 11b is an external perspective view showing the state in which the top surface of the cold insulation box 201 shown in Fig. 11a is closed. Fig. 11c is an external view showing the state in which the cold box 201 shown in Fig. 11a is folded.

This embodiment is shown in Figs. 11a to 11c, and the side surface 212d and the side surface facing it are the same as those shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b (Fig. 11a - Fig. 11c). The configuration of the side surface 212a and the side surface opposite thereto (not shown in FIGS. 11a to 11c) are different.

The side surface 212d and the side surface facing the same in this embodiment are composed of an upper side region 217a on the side of the lid portions 11a and 11b and a lower side region 217b on the bottom surface side. The upper side region 217a is formed by laminating a fabric (cloth) on the inner side of the cold-storage box 201 of an aluminum foil. The lower side region 217b is composed of one aluminum foil. Thereby, the upper side region 217a is harder than the lower side region 217b. A line 218 is formed at the boundary between the upper side region 217a and the lower side region 217b. The traces 218 extend parallel to the boundary between the "side surface 212d and the side surface facing the side" and the "cover portions 11b, 11a" at the same height as the second side of the isosceles trapezoidal regions 14a, 14b.

Further, in the side surface 212a and the side surface facing the same in the present embodiment, each of the triangular regions 16a and 16b is formed with a trace 219 extending from the side surface 212d and the side line 218 facing the side surface.

The cold-insulation box 201 having the above configuration is also folded and assembled in the same manner as those shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b. At this time, among the side faces 212d and the side faces facing therewith, a line 218 is formed at the boundary between the upper side region 217a and the lower side region 217b, whereby the boundary portion between the upper side region 217a and the lower side region 217b is easily folded. Further, the triangular regions 16a and 16b are also easily folded by the traces 219 on the side faces 212a and the side faces facing them. Further, the upper region 217a is made harder than the lower region 217b, whereby the upper region 217a is stretched and the cold box 20 is directly folded, and the side surface 212d and the side surface facing it are less likely to wrinkle.

Further, in the cold-insulation boxes 1 and 101 shown in FIGS. 1a to 1c and 9a to 9c, the side faces 12a and 112a and the triangular regions 16a, 16b, 116a, and 116b facing the side faces thereof may be formed. There are the same traces as the trace 219 shown in Figs. 11a to 11c.
