  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is an explanatory diagram showing a configuration of a cold-insulated interior body according to an embodiment of the present invention. 1A shows a developed state of the cold insulation interior body 10, FIG. 1B shows a state immediately before the cold insulation interior body 10 is assembled into the cold insulation container 30, and FIG. 1C shows the cold insulation container. 30 configurations are shown. As shown to Fig.1 (a), as for the cold insulation interior body 10, the some package bodies 11-16 are joined by the bending parts 21-25. Each package 11-16 is joined in the state which developed 6 sides of a rectangular parallelepiped. In this embodiment, as an example of the cold insulation heat interior body, a cold insulation interior body incorporated in a cold insulation container will be described.

  The packaging bodies 11-16 are packaging the cool storage materials 1-6, respectively. The cold storage materials 1 to 6 are sheet-shaped. The sheet-shaped cold insulation surface has a size corresponding to the six inner surfaces of the cold insulation container 30. On the other hand, the bent portions 21 to 25 can be bent with respect to the adjacent package. Accordingly, the cold insulation interior body 10 assembled as shown in FIG. 1B is integrated into the cold insulation space of the cold insulation container 30 shown in FIG. At this time, the packaging bodies 11 to 16 face the inner surface S11 of the bottom portion of the cold storage container 30, the inner surfaces S12 to S15 of the side portions, and the inner surface S16 of the lid portion, respectively, and stand in close contact with each other. In addition, the bending parts 21-25 are between the package bodies 11 and 13, between the package bodies 12 and 13, between the package bodies 13 and 14, between the package bodies 14 and 15, and between the package bodies 13 and 16, respectively. Are joined so that they can be bent. The expanded state is not limited to FIG. 1A, and may be an arbitrary expanded state.

  Here, since the cool storage materials 1-6 in each packaging body 11-16 are a sheet form, the packaging bodies 11-16 also become a thin sheet form. As a result, the cold insulation space of the cold insulation interior 10 is smaller than the cold insulation space of the cold insulation container 30 by the thickness of each of the packaging bodies 11 to 16, and even if the cold insulation interior 10 is incorporated in the cold insulation container 30, It will not be extremely small.

  When the cold insulation container 30 reaches the conveyance destination and the takeout of the product is completed, the cold insulation interior body 10 can be taken out from the cold insulation space of the cold insulation container 30 at a time. In addition, as shown in FIG. 1, by attaching the handle 41 to the cold insulation interior body 10, the cold insulation interior body 10 can be taken out from the cold insulation container 30 more easily.

  The cold insulation interior body 10 taken out from the cold insulation container 30 can be folded so that the packaging bodies 11 to 16 are stacked in parallel by folding the bent portions 21 to 25 as necessary. That is, it becomes possible to fold the packaging bodies 11 to 16 as a unit.

  In addition, as shown in FIG. 2, the two cool storage materials 1a and 1b corresponding to the cool storage materials 1, 3, 5, and 6 respectively on the packaging bodies 11, 13, 15, and 16 of the cool insulation interior body 10 shown in FIG. When 3a, 3b, 5a, 5b, 6a, 6b are accommodated, the bent portions 31, 32, 34, 33 are provided between the regenerator materials 1a, 1b, 3a, 3b, 5a, 5b, 6a, 6b. The package bodies 11, 13, 15, 16 can be divided into two package bodies 11a, 11b, 13a, 13b, 15a, 15b, 16a, 16b, respectively. Thereby, it can fold for the surface of each cool storage material 1a, 1b, 2, 3a, 3b, 4, 5a, 5b, 6a, 6b as a unit. In this case, it is preferable to make the surfaces of the respective cold storage materials the same because they are compact after folding.

  Furthermore, as shown in FIG. 3, the folding part 34 shown in FIG. 2 is deleted, the packaging bodies 15a and 15b are separated, and the packaging body 12 is provided via the folding part 35 newly provided with the separated packaging body 15b. You may make it connect to. Each package shown in FIG. 2 is symmetrical in the unfolded state. In this case, there is no bent portion between the package 15a and the package 15b, but a plurality of packages 15a and 15b are provided corresponding to one inner surface S15 of the cold container 30. In FIG. 3, two handles 40 a and 40 b are provided instead of the handle 40.

  Here, the several package which packages the cool storage material which has a cold insulating surface respond | corresponds to the inner surface of a cold insulating container. Specifically, in FIG. 1, a plurality of packaging bodies 11 to 16 for packaging the cold storage materials 1 to 6 having a cold insulation surface correspond to the inner surfaces S11 to S16 of the cold insulation container 30. Moreover, in FIG. 2, the package 11a, 11b, 12, 13a, 13b, 14, 15a, 15b, 16a which wraps the cool storage material 1a, 1b, 2, 3a, 3b, 4, 5a, 5b, 6a, 6b, respectively. 16b correspond to the inner surfaces S11 to S16 of the cold container 30. In particular, the two packaging bodies 11a and 11b correspond to one inner surface S11, the two packaging bodies 13a and 13b correspond to one inner surface S13, the two packaging bodies 15a and 15b correspond to one inner surface S15, The two packaging bodies 16 a and 16 b correspond to one inner surface 16. In FIG. 3, the two packaging bodies 15 a and 15 b correspond to the inner surface 16 in a state where they are cut off without being bent.

  In addition, the cold storage container 30 is also a foldable container as described in Patent Document 1. Therefore, at the time when the transportation of the commodity or the like is finished, the cold insulation interior body 10 and the cold insulation container 30 are folded into a compact state and then returned.

  Moreover, the cold insulation interior body 10 can be directly re-cooled and reused without the presence of a heat insulating material or the like. The re-cooling of the cold insulation interior 10 can reduce the cooling space by cooling in the folded state. Further, for example, when the cold-retained interior body 10 in the unfolded state is cooled in a state where it is hung on a bag or a car, the cooling space in contact with it becomes wider and the cooling time can be shortened. Further, the cold-retained interior body 10 in a developed state may be spread on a net or the like and cooled.

(Maintaining self-supporting state)
The packaging bodies 11 to 16 described above can maintain a self-supporting state by the rigidity of the packaging bodies 11 to 16 themselves or the rigidity of the cold storage materials 1 to 6 themselves. The above-described regenerator materials 1 to 6 are in a sheet form, and for example, if the regenerator material is in a gel state even in a regenerative state, the rigidity of the packaging bodies 11 to 16, particularly the packaging bodies 12 to 15, needs to be high because the rigidity is somewhat low. There is. That is, the cold-insulated interior body 10 is made independent by the surface structure. At this time, the rigidity of the packaging bodies 11 and 16 does not necessarily have to be strong, and the packaging bodies 12 to 15 corresponding to the side surfaces have desired rigidity. Note that it is not necessary to increase the rigidity of all of the packaging bodies 12 to 15, and the rigidity of two adjacent packaging bodies, for example, 12 and 13, whose cross section is L-shaped, is higher than the rigidity of the other packaging bodies. Then, the cold insulation interior body 10 may be made independent.

  In addition, as shown in FIG. 4, each package 11-16 is good also as a mesh-shaped package instead of the sealed package. Here, when the cold storage materials 1 to 6 have low rigidity, it is preferable to use a high-rigidity material such as metal for the mesh wire as the core material. 4A is a cross-sectional view taken along the line AA in FIG. 4B.

  When the mesh-shaped package is used, the mesh-shaped package functions as a spacer provided between the cold storage material and the inner surface of the cold storage container 30, and the cold storage material does not directly touch the inner surface of the cold storage container 30. Insulation / cooling effect can be enhanced. For example, a netron sheet can be used as the mesh-shaped package.

  On the other hand, as shown in FIG. 5, core materials 21 a to 25 a such as metal or reinforced plastic may be embedded in the bent portions 21 to 25. In this case, even if the rigidity of each package 11-16 is low, a self-supporting state can be hold | maintained by the shaft structure of the bending parts 21-25. If possible, as shown in FIG. 6, it is preferable to embed a core material in all sides of the packaging bodies 11 to 16 to maintain the self-supporting state of the cold-insulated interior body 10. In FIG. 6, side parts 51 to 64 are provided in addition to the bent parts 21 to 25, and a core material is embedded in the side parts 51 to 64.

  In embodiment mentioned above, the cold storage materials 1-6 accommodated in the cold storage container 30 can be taken out easily, without affecting the structure of the cold storage container 30. Moreover, the cold insulation interior body 10 can be folded and can be returned in a compact state. Furthermore, since there is no heat insulating material outside the cold insulation interior body 10, it is possible to efficiently recool the taken out cold storage materials 1-6.

(Folding structure by crushing)
In the above-described embodiment, all of the packaging bodies 11 to 16 can be developed. However, as shown in FIG. 7, a part of the packaging bodies 11 to 16 is developed through a plurality of bent portions. It may be a closed structure that is impossible and can be folded by crushing. In FIG. 7, the bending part 26 is further provided and the side packaging bodies 12-15 are joined by the four bending parts 22-24,26. When the wrapping bodies 12 to 15 are crushed, the wrapping bodies 12 to 15 have a parallelogram in the middle and are finally folded.

  Since the cold insulation interior body shown in FIG. 7 having a structure that can be folded by crushing is joined in a closed structure with the side packaging bodies 12 to 15 by the four bent portions 22 to 24 and 26, It becomes easier to maintain a self-supporting state. Moreover, when the regenerator materials 1 to 6 are recooled, for example, when they are in a self-supporting state, the contact area with the cooling space is increased and can be efficiently performed.

(Width of bent part)
The bent portions 21 to 25 described above have a minimum width that allows the cold insulation interior body 10 to be in close contact with the inner surface of the cold insulation container 30. The widths of the bent portions 21 to 25 are provided with an allowance so as to have a margin for accommodating a plurality of cold storage containers having a plurality of different cold storage spaces, like the bent portions 71 to 75 shown in FIG. It is preferable. It is preferable that the stretch allowance is maximized when the packaging bodies 11 to 16 are in close contact with the inner surface of the cold storage container having the maximum cold storage space.

  The folding structure of the bent portions 71 to 75 having the extension allowance may be a wide continuous member, or may be a plurality of narrow strip members assembled in a comb shape or a zigzag shape.

  In the above-described embodiment, the cold insulation container 30 and the cold insulation interior body 10 are rectangular boxes. However, the present invention is not limited to this, and for example, a columnar box having many side faces may be used. Moreover, the packaging bodies 11-16 do not need to be provided corresponding to all six surfaces. For example, the packaging body 11 corresponding to the bottom surface may not be provided. In this case, even if a product or the like is present in the cold insulation container 30, only the cold insulation interior body 10 can be easily taken out.

  Furthermore, the above-described cold insulation container 30 is formed of a heat insulating material. The heat insulating material is formed of, for example, foamed polystyrene or foamed urethane. The heat insulating material may be a vacuum heat insulating material. For example, as the vacuum heat insulating material, a known material in which a core material is covered with a laminate film and the inside is reduced in vacuum to be sealed may be used.
