As shown in FIGS. 1 and 2, the heat insulating container 10 according to this embodiment is capable of being assembled and folded, and includes six panels 11 to 16. The panels 11 to 16 have a substantially rectangular parallelepiped shape when assembled, and include a top panel 11, a front panel 12, a back panel 13, a right panel 14, a left panel 15, and a bottom panel 16. I'm here. The top panel 11, the front panel 12, the back panel 13, the right panel 14, the left panel 15, and the bottom panel 16 are arranged so that their main surfaces (the widest of the six surfaces constituting each panel) A pair of opposing surfaces) each have a substantially rectangular shape or a substantially square shape. Further, the front panel 12 and the back panel 13 have their main surfaces having substantially the same size, and the right panel 14 and the left panel 15 have their main surfaces having substantially the same size. are doing. Each of the panels 11 to 16 is made of a rigid plate-like member and is designed not to be flexibly deformed during use.

The panels 11 to 16 are provided so that they can be assembled and folded as a whole, and take an assembled state in which they are assembled into a box shape (FIGS. 1 to 5) and a folded state in which they are folded into a small size (FIGS. 6 to 8). be able to.

When the heat insulating container 10 is in an assembled state, the top panel 11 and the bottom panel 16 face each other, the right panel 14 and the left panel 15 face each other, and the back panel 13 and front panel 12 face each other. Further, the bottom panel 16 is surrounded by the front panel 12 , the back panel 13 , the right panel 14 , and the left panel 15 . The bottom panel 16 is foldable relative to the back panel 13. The right panel 14 and the left panel 15 each include a fixed panel (first right panel 14a, first left panel 15a) fixed to the back panel 13, and a movable panel (first right panel 14a, first left panel 15a) that is movable relative to the fixed panel. A second right side partial panel 14b, a third right side partial panel 14c, a second left side partial panel 15b, and a third left side partial panel 15c). Further, in the folded state (FIGS. 6 to 8) in which the heat insulating container 10 is folded, the bottom panel 16 is divided into a fixed panel of the right panel 14 (the first right section panel 14a) and a fixed panel of the left panel 15 (the first left section). It is accommodated between the panel 15a).

In the assembled state, the heat insulating container 10 is surrounded by six panels 11 to 16, thereby forming a substantially rectangular parallelepiped-shaped storage space 20 for storing a loaded object. Each of the six panels 11 to 16 includes a heat insulating panel, as will be described later. For this reason, the housing space 20 is surrounded by a heat insulating material, thereby restricting the inflow and outflow of heat to and from the outside, and can maintain heat insulation properties. Furthermore, at least some of the six panels 11 to 16 are provided movably relative to the adjacent other panels 11 to 16, respectively. Thereby, the heat insulating container 10 can be changed from an assembled state in which the storage space 20 is formed to a folded state in which the storage space 20 is not formed, and can be changed from the folded state to the assembled state. Therefore, when the heat insulating container 10 is not used, by folding the panels 11 to 16, it is possible to store the container in a smaller overall size than in the assembled state. Further, in the assembled state, each of the six panels 11 to 16 has its peripheral edge in close contact with one of the other panels 11 to 16, thereby ensuring the airtightness of the housing space 20.

Next, the configuration of each panel 11 to 16 will be further explained. In addition, in the following, "panels 11 to 16 (partial panels) are parallel (perpendicular) to a predetermined surface" means "the main surfaces of panels 11 to 16 (partial panels) are parallel to a predetermined surface" It means "parallel (perpendicular)".

Furthermore, the width of the movable panel, that is, the total width L7 (=L4+L5) of the second right side partial panel 14b and the third right side partial panel 14c (the second left side partial panel 15b and the third left side partial panel 15c) is the bottom panel 16. It is preferable that the width (length in the X direction) is more than 1/3 of L2 (L4+L5=L7>L2/3). As a result, when folding the right panel 14 and the left panel 15, the movable panels of the right panel 14 (the second right panel 14b and the third right panel 14c) and the movable panels of the left panel 15 (the second left panel 15b and the third left side partial panel 15c), it is possible to prevent only one movable panel from being folded and the other movable panel from not being folded. Thereby, after the heat insulating container 10 is folded, it is possible to suppress the difference in thickness between the right panel 14 side and the left panel 15 side.

In addition, combining the above, the width of the movable panel, that is, the total width L7 of the second right side partial panel 14b and the third right side partial panel 14c (the second left side partial panel 15b and the third left side partial panel 15c) is the width of the bottom panel 16. It is more preferable that the width L2 is more than 1/3 and less than 1/2 (L2/3<L4+L5=L7≦L2/2).

Further, as shown in FIG. 4, in the assembled state, the height (Z direction length) H1 of the right panel 14 (left panel 15) is preferably 500 mm or more and 1200 mm or less, and preferably 700 mm or more and 1000 mm or less. More preferred. Furthermore, the total height (length in the Z direction) H2 of the heat insulating container 10 is preferably 600 mm or more and 1300 mm or less, and more preferably 800 mm or more and 1100 mm or less. According to this embodiment, the movable panels of the right panel 14 (the second right panel 14b and the third right panel 14c) and the movable panels of the left panel 15 (the second left panel 15b and the third left panel 15c) is foldable. Therefore, when assembling the heat insulating container 10, the right panel 14 and the left panel 15 can be expanded by pulling the movable panel of the right panel 14 and the movable panel of the left panel 15 from the outside. Thereby, even if the total height H2 of the heat insulating container 10 exceeds the length of a person's hand (for example, 600 mm or more), there is no need to insert a hand into the heat insulating container 10 from above. Further, when assembling the heat insulating container 10, it is easy to make the right side panel 14 and the left side panel 15, especially the bottom side, perpendicular to the bottom side panel 16.

Further, the depth (length in the Y direction) L6 (see FIG. 3) of the bottom panel 16 is preferably less than or equal to the height (length in the Z direction) H1 (see FIG. 4) of the right panel 14 and the left panel 15 (see FIG. 4). L6≦H1). Thereby, in the folded state, the bottom panel 16 does not protrude from the upper end of the right panel 14 (left panel 15), making it easier to accommodate the panels 11 to 16.

Note that the "height" of each of the panels 11 to 16 refers to the length of each of the panels 11 to 16 in the direction from the bottom panel 16 to the top panel 11. The "width" of each panel 11-16 refers to the length in the direction parallel to the main surface of each panel 11-16 and perpendicular to the height direction of each panel 11-16. The "thickness" of each panel 11-16 refers to the length in the direction perpendicular to the main surface of each panel 11-16.

(Internal structure of panel)
Next, the structure of each panel 11 to 16 will be further explained.

Each of the panels 11 to 16 is composed of a heat insulating panel having heat insulating properties as described above. The heat insulating material used in such a heat insulating panel may be any material as long as it exhibits the desired heat insulating properties, such as fiber-based heat insulating materials such as glass wool, rock wool, cellulose fiber, and insulation board, wool, carbonized cork, etc. natural material insulation materials, polyethylene foams such as extruded polystyrene foam and bead polystyrene foams, polyurethane foams such as rigid urethane foams, polyethylene foams such as highly foamed polyethylene, foam insulation materials such as phenol foams, and vacuum insulation materials. etc. can be mentioned.

As the heat insulating material, plastic Dan (hollow structure), polypropylene plastic pearl (registered trademark by Kawakami Sangyo Co., Ltd.), and polyethylene twin cone (registered trademark by Ube Eximo Co., Ltd.) may be used as the heat insulating material. In this case, hollow plastic cardboard made of polypropylene or polyethylene can be used.

As the vacuum heat insulating material, one having a core material and an exterior material may be used. As the core material, for example, porous bodies such as powders such as silica, foams such as urethane polymers, and fibrous bodies such as glass wool may be used. The exterior material is a member that covers the outer periphery of the core material, and may be a flexible sheet in which a heat-welding layer and a gas barrier layer are laminated in this order from the core material. The gas barrier layer may be a metal foil, a vapor-deposited sheet in which a vapor-deposited layer is formed on one side of a resin sheet, or the like. For example, aluminum can be used as the metal foil. For example, aluminum, aluminum oxide, or silicon oxide can be used for the vapor deposition layer. Further, the foamed heat insulating material can be arranged adjacent to at least the accommodation space 20 side of the vacuum heat insulating material. Furthermore, a heat insulating envelope may be formed to surround the vacuum heat insulating material.

Furthermore, the panels 11 to 16 may be made of radio wave transparent non-metallic members. In this case, when the IC tag is placed inside the heat insulating container 10, the information on the IC tag can be read from outside the heat insulating container 10 by a reading device via non-contact communication.

(Configuration of outer bag)
As shown in FIG. 9, the entire outer surface of each panel 11 to 16 is covered with an outer bag 30 having heat insulating properties.

This outer bag 30 has a top cover 31, a first front cover 32a, a second front cover 32b, a back cover 33, a right cover 34, a left cover 35, and a bottom cover 36. . Of these, the top cover 31 is attached to the top panel 11. Moreover, the first front cover 32a and the second front cover 32b are attached to the first front partial panel 12a and the second front partial panel 12b, respectively. Note that the first front cover 32a and the second front cover 32b may be attached to and detached from each other using an attachment/detachment tool such as a hook-and-loop fastener (not shown). Furthermore, the back cover 33 is attached to the back panel 13. Note that the right cover 34, left cover 35, and bottom cover 36 are not directly attached to the right panel 14, left panel 15, and bottom panel 16, respectively.

In the assembled state shown in FIGS. 1 to 5, the top cover 31 covers the top panel 11, the first front cover 32a covers the first front partial panel 12a, and the second front cover 32b covers the second front partial panel 12b. cover. Further, the back cover 33 covers the back panel 13, and the right cover 34 covers the right panel 14. Furthermore, the left cover 35 covers the left panel 15 and the bottom cover 36 covers the bottom panel 16. In this way, in the assembled state, the heat insulating container 10 is entirely covered by the outer bag 30 having heat insulating properties, so that heat transfer to the accommodation space 20 can be further suppressed.

In the folded state shown in FIGS. 6 to 8, the top cover 31 covers the top panel 11, the first front cover 32a covers the first front partial panel 12a, and the second front cover 32b covers the second front partial panel 12b. , and the back cover 33 covers the back panel 13. On the other hand, as described above, the right cover 34, left cover 35, and bottom cover 36 are not directly attached to the right panel 14, left panel 15, and bottom panel 16, respectively. Therefore, the right cover 34, the left cover 35, and the bottom cover 36 are folded around the right panel 14, left panel 15, and bottom panel 16, respectively.

Further, as shown in FIG. 9, attachment/detachment tools 37 such as hook-and-loop fasteners are attached to the right cover 34 and the left cover 35, respectively. The right cover 34 and the left cover 35 are removably fixed in the folded state by the attachment/detachment tool 37, and the heat insulating container 10 is held in the folded state (see FIG. 6).

In this way, the top panel 11, the first front panel 12a, the second front panel 12b, and the back panel 13 are each attached to the outer bag 30. Further, the first right side partial panel 14a is fixed to the back panel 13, the second right side partial panel 14b is attached to the first right side partial panel 14a via the first right side hinge member 24a, and the third right side partial panel 14c is fixed to the first right side partial panel 14a. It is attached to the second right side partial panel 14b via the second right side hinge member 24b. Further, the first left partial panel 15a is fixed to the back panel 13, the second left partial panel 15b is attached to the first left partial panel 15a via the first left hinge member 25a, and the third left partial panel 15c is attached to the first left partial panel 15a. It is attached to the second left side partial panel 15b via the second left side hinge member 25b. Further, the bottom panel 16 is attached to the back panel 13 via a bottom hinge member 26a. In this way, since the panels 11 to 16 are all directly or indirectly attached to the outer bag 30, when the panels 11 to 16 are folded, each panel 11 to 16 does not fall off from the other panels 11 to 16. It is designed not to.

This outer bag 30 may be made of, for example, a heat shielding sheet. The heat shielding sheet may be a non-metallic member that transmits radio waves, and has sufficiently low transmittance to visible light and sufficiently high reflectivity to infrared rays. The heat shielding sheet constituting the outer bag 30 may be made of stretched or unstretched plastic such as polyester such as polyethylene terephthalate and polyethylene naphthalate, polypropylene, polycarbonate, cellulose acetate, polyethylene, polyvinyl chloride, polyamide, and polymethylpentene. Films, sheets, etc., sheets or nonwoven fabrics made of natural fabrics, synthetic resin fibers, etc. can be used. Furthermore, an alloy or a stack of two or more of these materials may be used. In order to provide these various resin films and sheets with light-shielding properties and reflectivity of visible light and infrared rays as necessary, non-metallic white materials such as titanium oxide, barium sulfate, zinc oxide, zinc sulfide, and calcium carbonate are used. It may be colored by printing, painting, etc. with ink using pigments. In addition, there are no particular restrictions on the thickness of the heat shield sheet perpendicular to the sheet surface direction, but considering the flexibility and durability of the heat shield sheet, visible light and infrared transmittance, reflectivity, etc. .2 mm or more and 15.0 mm or less. In this way, when the heat shield sheet is made of a non-metallic material that transmits radio waves, when an IC tag is placed inside the heat insulating container 10, it can be read from outside the heat insulating container 10 by a reader through non-contact communication. It becomes possible to read the information on the IC tag.

(Disassembly and assembly of insulation container)
Next, the operation when disassembling and assembling the heat insulating container 10 will be explained.

(Disassembly of insulated container)
First, the operation when the assembled heat insulating container 10 (see FIGS. 1 to 5) is disassembled into the disassembled heat insulating container 10 (see FIGS. 6 to 8) will be described.

First, assume that six panels 11 to 16 are assembled into a box shape as shown in FIGS. 1 to 5, and the heat insulating container 10 is in an assembled state. At this time, a substantially rectangular parallelepiped-shaped accommodation space 20 is formed between each of the panels 11 to 16. Although not shown, a load such as food may be stored in the storage space 20.

Next, the top panel 11 is rotated with respect to the back panel 13 and moved to the back side of the back panel 13 (the positive side in the Y direction). At this time, the top panel 11 is arranged so as to hang down from the back panel 13 and is arranged parallel to the back panel 13.

Subsequently, the bottom panel 16 is folded onto the back panel 13 via the bottom hinge member 26a. At this time, the bottom panel 16 is folded so as to overlap the inside of the back panel 13 (on the negative side in the Y direction). Further, at this time, the bottom panel 16 is accommodated between the first right side partial panel 14a and the first left side partial panel 15a.

Next, the second right side partial panel 14b and the third right side partial panel 14c of the right side panel 14 are folded via the first right side hinge member 24a and the second right side hinge member 24b, respectively. At this time, the second right partial panel 14b and the third right partial panel 14c are folded inward with respect to the first right partial panel 14a. Further, the second right side partial panel 14b and the third right side partial panel 14c are arranged between the folded bottom panel 16 and the front panel 12, and are respectively perpendicular to the horizontal plane (XY plane) and vertical to the back panel 13 (ZX parallel to the plane).

Similarly, the second left side partial panel 15b and the third left side partial panel 15c of the left side panel 15 are folded via the first left side hinge member 25a and the second left side hinge member 25b, respectively. At this time, the second left partial panel 15b and the third left partial panel 15c are folded inward with respect to the first left partial panel 15a. Further, the second left partial panel 15b and the third left partial panel 15c are arranged between the folded bottom panel 16 and the front panel 12, and are respectively perpendicular to the horizontal plane (XY plane) and vertical to the rear panel 13 (ZX parallel to the plane).

As described above, the bottom panel 16 is housed in advance between the first right partial panel 14a and the first left partial panel 15a. Therefore, when folding the second right side partial panel 14b and the third right side partial panel 14c of the right side panel 14 (the second left side partial panel 15b and the third left side partial panel 15c of the left side panel 15), the folded bottom panel 16 There is no fear of interference with the second right partial panel 14b (second left partial panel 15b), and the second right partial panel 14b (second left partial panel 15b) can be folded smoothly.

Thereafter, the front panel 12 is moved parallel to the back panel 13 in the Y direction plus side, and the front panel 12 is brought closer to the third right partial panel 14c and the third left partial panel 15c.

In this way, the six panels 11-16 of the heat-insulating container 10 are in the folded state shown in FIGS. 6-8 as a whole. Finally, the right cover 34 and the left cover 35 of the outer bag 30 may be fixed in the folded state using the attachment/detachment tool 37. As described above, when the heat insulating container 10 is not used, the panels 11 to 16 can be folded to make the overall volume as small as possible for storage and transportation.

(Assembling the insulation container)
The insulating container 10 can be assembled by performing the disassembly method described above in the reverse order. That is, first, after removing the attachment/detachment tool 37, the front panel 12 is moved parallel to the back panel 13 in the Y direction minus side, and the front panel 12 is separated from the third right side partial panel 14c and the third left side partial panel 15c. .

Next, by unfolding and assembling the second right side partial panel 14b and the third right side partial panel 14c of the right side panel 14 (the second left side partial panel 15b and the third left side partial panel 15c of the left side panel 15), each position parallel to.

Subsequently, the bottom panel 16 is rotated toward the horizontal plane (XY plane). At this time, the bottom panel 16 is arranged parallel to the horizontal plane (XY plane) and surrounded by the front panel 12, the back panel 13, the right panel 14, and the left panel 15.

after that. The top panel 11 is rotated relative to the back panel 13 and placed above the front panel 12, the back panel 13, the right panel 14, and the left panel 15. At this time, the top panel 11 is arranged parallel to a horizontal plane (XY plane). In this way, the six panels 11-16 of the insulated container 10 are assembled as a whole as shown in FIGS. 1-5.

As described above, according to the present embodiment, the plurality of panels 11 to 16 can take an assembled state in which they are assembled into a box shape and a folded state in which they are folded into a small size. Thereby, by bringing the panels 11 to 16 into an assembled state, it is possible to form a highly airtight storage space 20 in which a loaded object can be stored inside the panels 11 to 16. On the other hand, when the heat insulating container 10 is not used, the heat insulating container 10 can be stored compactly by folding the panels 11 to 16.

Further, according to the present embodiment, in the assembled state, the bottom panel 16 is arranged so as to be surrounded by the front panel 12, the back panel 13, the right panel 14, and the left panel 15 (side panels 12 to 15). Thereby, the heat insulation of the accommodation space 20 can be improved. Further, in the assembled state, the side panels 12 to 15 are sandwiched between the outer bag 30 and the outer periphery of the bottom panel 16, so that the side panels 12 to 15 can be stably held.

Further, according to the present embodiment, the first right partial panel 14a and the first left partial panel 15a are each fixed to the back panel 13, and in the folded state, the bottom panel 16 is connected to the first right partial panel 14a. It is accommodated between the first left side partial panel 15a and the first left side partial panel 15a. As a result, while the heat insulating container 10 is being moved from the assembled state to the folded state, the bottom panel 16 folded earlier than the side panels 12 to 15 becomes an obstacle, causing the second right side partial panel 14b and the third right side partial panel 14c. (movable panel), the second left side partial panel 15b, and the third left side partial panel 15c (movable panel) are prevented from becoming difficult to fold. As a result, the heat insulating container 10 can be folded smoothly, and the folded heat insulating container 10 can be made compact.

Further, according to the present embodiment, the movable panels of the right panel 14 and the left panel 15 include a plurality of partial panels (the second right panel 14b, the third right panel 14c, the second left panel It is composed of a partial panel 15b and a third left side partial panel 15c). As a result, even if the total height H2 of the insulating container 10 is high and exceeds the length of a person's hand, there is no need to reach from above the insulating container 10 when the insulating container 10 is assembled. . As a result, it is possible to easily arrange the right panel 14 and the left panel 15, especially the bottom surfaces, perpendicularly to the bottom panel 16.

Further, according to this embodiment, the top panel 11 is foldably attached to the back panel 13 via the top hinge member 21a. Thus, when the heat insulating container 10 is folded, the top panel 11 is wrapped around the outside of the back panel 13, so that the top panel 11 does not interfere with the folding of the other panels 12 to 16.

Further, according to the present embodiment, each of the panels 11 to 16 is a rigid plate-like member. This prevents the panels 11 to 16 from being flexibly deformed, so that the heat insulating container 10 becomes a rectangular parallelepiped in the assembled state, and the accommodation space 20 can be reliably formed.

Further, according to this embodiment, each panel 11 to 16 is covered with an outer bag 30. Thereby, the airtightness of the storage space 20 can be further improved, and a decrease in the heat insulation properties of the heat insulating container 10 can be suppressed.

Further, according to the present embodiment, the plurality of panels 11 to 16 include a top panel 11, a front panel 12, a back panel 13, a right panel 14, a left panel 15, and a bottom panel 16. As a result, the storage space 20 is covered from all directions by the panels 11 to 16, so that the loaded items in the storage space 20 can be protected from all directions.

Further, according to the present embodiment, the front panel 12 includes a plurality of foldable front panel panels 12a and 12b, and can be opened and closed in a double-door shape. Thereby, by folding the front partial panels 12a and 12b, the front side of the heat insulating container 10 is opened, and it becomes easy to take out the loaded items from the storage space 20 and to store them in the storage space 20.

In this embodiment, the bottom panel 16 is foldable with respect to the back panel 13, and the first right partial panel 14a and the first left partial panel 15a (fixed panel) are foldable with respect to the rear panel 13. The explanation has been given by taking the case where it is fixed as an example. However, the present invention is not limited thereto, and the bottom panel 16 is foldable with respect to the front panel 12, and the first right partial panel 14a and the first left partial panel 15a (fixed panel) are each fixed to the front panel 12. may be done. In this case, the right panel 14 corresponds to the first side panel, the left panel 15 corresponds to the second side panel, the front panel 12 corresponds to the third side panel, and the back panel 13 corresponds to the fourth side panel. It's okay. Alternatively, the left panel 15 corresponds to the first side panel, the right panel 14 corresponds to the second side panel, the front panel 12 corresponds to the third side panel, and the back panel 13 corresponds to the fourth side panel. Also good.

Preferably (L8≦(L2/2)). Thereby, in the folded state shown in FIG. 11, the second right side partial panel 14d and the second left side partial panel 15d are prevented from interfering with each other. As a result, the heat insulating container 10 can be folded into a smaller size, and it is possible to prevent scratches and the like from occurring on the second right side panel 14d and the second left side panel 15d.

In this case, the width (length in the Y direction) L9 of the first right partial panel 14a is different from the width (length in the Y direction) L10 of the first left partial panel 15a. Specifically, the width L9 of the first right partial panel 14a is longer than the width L10 of the first left partial panel 15a (L9>L10). Note that the present invention is not limited to this, and the width L10 of the first left partial panel 15a may be longer than the width L9 of the first right partial panel 14a (L10>L9).

As shown in FIG. 13, in the folded state, the second right partial panel 14d and the second left partial panel 15d are arranged between the front panel 12 and the bottom panel 16 so as to overlap each other. Specifically, the second left partial panel 15d is located between the bottom panel 16 and the second right partial panel 14d, and the second right partial panel 14d is located between the second left partial panel 15d and the front panel 12. located in between. Further, the second right side partial panel 14d and the second left side partial panel 15d are respectively arranged perpendicular to the horizontal plane (XY plane) and parallel to the back panel 13 (ZX plane).

In FIG. 12, the width (length in the Y direction) L11 of the second right partial panel 14d and the width (length in the Y direction) L12 of the second left partial panel 15d are the width (length in the X direction) of the bottom panel 16, respectively. It is preferable that it is below L2 (L11≦L2, L12≦L2). As a result, in the folded state shown in FIG. 13, the second left partial panel 15d is prevented from interfering with the first right partial panel 14a, and the second right partial panel 14d is prevented from protruding toward the first left partial panel 15a. can be suppressed. Further, the heat insulating container 10 can be folded into a smaller size, and it is possible to prevent scratches and the like from occurring on the second left side panel 15d and the first right side panel 14a.

Note that the difference (L9-L10) between the width L9 of the first right side partial panel 14a and the width L10 of the first left side partial panel 15a is equal to or greater than the thickness (X direction length) T2 of the second right side partial panel 14d. is preferable ((L9-L10)≧T2). Thereby, in the folded state, the second left partial panel 15d can be easily accommodated between the first bottom panel 16 and the second right partial panel 14d.

(Modification 3)
FIG. 14 shows a heat insulating container 10 according to a third modification. In FIG. 14, the top panel 11 is removable, and the top hinge member 21a is not provided. That is, the top panel 11 does not need to be attached to the back panel 13 and the outer bag 30 in advance.

In this case, a part of the inner surface 14e (inner surface 15e) of the second right partial panel 14b (second left partial panel 15b) contacts the first right partial panel 14a (first left partial panel 15a).

In this case, the width of the movable panel, that is, the total width L7 (=L4+L5) of the second right side partial panel 14b and the third right side partial panel 14c (the second left side partial panel 15b and the third left side partial panel 15c) is The width (length in the X direction) is preferably less than half of L1 (L4+L5=L7≦L1/2). As a result, when folding the right panel 14 and the left panel 15, the movable panels of the right panel 14 (the second right panel 14b and the third right panel 14c) and the movable panels of the left panel 15 (the second left panel 15b and the third left side partial panel 15c) are prevented from interfering with each other. As a result, the heat insulating container 10 can be folded into a smaller size, and scratches and the like occur on the second right side panel 14b and the third right side panel 14c, and on the second left side panel 15b and the third left side panel 15c. You can suppress things.

Further, the width of the movable panel, that is, the total width L7 (=L4+L5) of the second right side partial panel 14b and the third right side partial panel 14c (the second left side partial panel 15b and the third left side partial panel 15c) is the width of the back panel 13. It is preferable that the width (length in the X direction) is more than 1/3 of L1 (L4+L5=L7>L1/3). As a result, when folding the right panel 14 and the left panel 15, the movable panels of the right panel 14 (the second right panel 14b and the third right panel 14c) and the movable panels of the left panel 15 (the second left panel 15b and the third left side partial panel 15c), it is possible to prevent only one movable panel from being folded and the other movable panel from not being folded. Thereby, after the heat insulating container 10 is folded, it is possible to suppress the difference in thickness between the right panel 14 side and the left panel 15 side.

In addition, combining the above, the width of the movable panel, that is, the total width L7 of the second right side partial panel 14b and the third right side partial panel 14c (the second left side partial panel 15b and the third left side partial panel 15c) is equal to the width of the bottom panel 16. It is more preferable that the width L1 is more than 1/3 and less than 1/2 (L1/3<L4+L5=L7≦L1/2).

It is also possible to appropriately combine the plurality of components disclosed in the above embodiments and modifications as necessary. Alternatively, some components may be deleted from all the components shown in the above embodiments and modifications.
