The thermal insulation / cold insulation container 10 includes one opening 14 that opens upward at the top of the container body 12. In the embodiment, the plurality of lids 16, 18 are arranged side by side at a rear edge (one edge) of the opening 14 in the container body 12 and hingedly connected. In the thermal insulation / cold insulation container 10, an item 80 is put in and taken out of the item storage chamber 12a through the opening 14 by opening a part or all of the plurality of lids 16, 18. In addition, the thermal insulation / cold insulation container 10 includes a heat insulating member 28 having heat insulating properties in the container body 12 and the lids 16, 18, and the item storage chamber 12a is kept at a predetermined temperature such as low temperature, normal temperature, or high temperature. The thermal insulation / cold storage container 10 is a square in plan view, and the relationship between the front-to-back, left-to-right, top-to-bottom lengths can be changed as appropriate, but the thermal insulation / cold storage container 10 in the embodiment is a rectangular parallelepiped that is long in the left-to-right direction. Also, the opening 14 of the container body 12 may be opened and closed by three or more lids, but the embodiment illustrates a configuration in which one opening 14 provided at the top of the container body 12 is opened and closed by two lids 16, 18.

[0016] 9, the container body 12 of the embodiment includes a main body portion 20 configured in a box shape with an open top, an outer bag 22 covering the outside of the main body portion 20, and an inner bag 24 covering the inside of the main body portion 20. In the container body 12, the main body portion 20 is disposed inside the outer bag 22, and the outer bag 22 forms the outer surface of the container body 12. In the container body 12, the inner bag 24 is disposed inside the main body portion 20, and the inner bag 24 forms the inner surface of the item storage chamber 12a.

[0017] 6 to 8, the main body 20 of the embodiment is configured in a box shape with a bottom by combining a plurality of panels 26. In the embodiment, the bottom, front wall, rear wall, left wall, and right wall of the main body 20 are each configured with a separate panel 26. Each panel 26 is a hard plate-like body having sufficient rigidity to be self-supporting. In the main body 20 of the embodiment, adjacent panels 26 are joined together by sewing or welding the skins 30 of the panels 26, which will be described later.

[0018] As shown in Figs. 6 to 8, each panel 26 includes a heat insulating member 28 having heat insulating properties and a skin 30 covering the outside of the heat insulating member 28. The heat insulating member 28 is plate-shaped. For example, foam-based heat insulating materials made of foam such as urethane foam, polystyrene foam, and phenol foam, vacuum heat insulating materials in which the air inside is removed and put into a vacuum state, and inorganic heat insulating materials such as glass wool or rock wool can be used alone or in combination. For example, the heat insulating member 28 is exemplified by a vacuum heat insulating material sandwiched between two sheets of foam-based heat insulating materials. In addition, from the viewpoints of heat insulating property, rigidity, cost, and the like, a hard foam is preferable, and among these, polystyrene foam and polyurethane foam are preferable. The skin 30 of the embodiment is a bag-shaped material capable of storing the heat insulating member 28 by combining sheets by sewing, welding, or the like to form a three-dimensional shape. For the sheet constituting the skin 30, a plastic sheet such as polyvinyl chloride, a composite sheet of a plastic sheet and an aluminum vapor deposition film, or a sheet of other material can be used.

[0019] As shown in Fig. 9, the outer bag 22 is formed by combining sheets by sewing, welding, etc., into a three-dimensional shape with an open top and a bottom. The sheets constituting the outer bag 22 may be plastic sheets such as polyvinyl chloride sheets, composite sheets of plastic sheets and aluminum vapor deposition films, or sheets of other materials. It is preferable that the bottom part of the outer bag 22 is made of a sheet having higher strength, such as abrasion resistance, than the wall parts of the outer bag 22. This can protect the bottom, which is easily rubbed against the floor, and improve the lifespan of the thermal insulation / cold storage container 10.

[0020] As shown in Figs. 6 to 8, the upper part of the container body 12 has a stepped shape with the outer edge being higher than the inner part on the article storage chamber 12a side.

The lid support surface 32 and the lid enclosure pieces 34 are provided on the front, rear, left and right opening edges of the opening 14 of the container body 12. In the embodiment, the protruding dimension of the lid enclosure pieces 34 from the lid support surface 32 is set to approximately the thickness of the lid bodies 16, 18. When the multiple lid bodies 16, 18 are closed, the lid bodies 16, 18 are fitted between the front, rear, left and right lid enclosure pieces 34. Thus, the periphery of the multiple lid bodies 16, 18 is covered with the lid enclosure piece 34. The lid enclosure piece 34 of the embodiment is formed by overlapping a skin 30 connected to the panel 26 constituting the main body 20 with a portion of the outer bag 22 that protrudes upward beyond the main body 20. In addition, the skin 30 extending from the panel 26 constituting the lid enclosure piece 34 and the outer bag 22 are joined together with double-sided tape or the like to be integrated. By forming the lid enclosure piece 34 by overlapping multiple sheets in this manner, the strength of the lid enclosure piece 34 can be improved.

[0021] As shown in FIG. 9, the inner bag 24 is formed into a three-dimensional shape with an open top and a bottom by assembling sheets by sewing, welding, or the like. It is preferable that the inner bag 24 has a structure that does not leak or is difficult to leak liquid. The upper end of the inner bag 24 is provided with a flange extending outward. The inner bag 24 is attached to the main body 20 by joining a hook-and-loop fastener arranged on the lower surface of the flange to a hook-and-loop fastener arranged on the upper surface of the main body 20. The sheet constituting the inner bag 24 may be a plastic sheet such as polyvinyl chloride, a composite sheet of a plastic sheet and an aluminum vapor deposition film, or a sheet of other material. In this way, by forming the inner surface of the item storage chamber 12a with the inner bag 24 that is detachable from the main body 20, the inner bag 24 that has a defect such as damage or dirt can be easily replaced.

[0022] As shown in Figs. 1 to 7, the heat / cold insulation container 10 of the embodiment includes a first lid body 16 and a second lid body 18 provided adjacent to the first lid body 16 as lid bodies.

The hinge 60a of the inner lid 60 is provided in the center in the left-right direction. The inner lid 60 is not limited to being folded in two as in the embodiment, but may be folded in three or more, but it is preferable to set the number of folds according to the number of the lid bodies 16, 18. In addition, the folding position of the inner lid 60 may be arranged to be aligned with the seam of the adjacent lid bodies 16, 18 as in the embodiment, or may be arranged to be shifted from the seam of the adjacent lid bodies 16, 18.

[0037] The heat and cold storage container 10 has a storage section 64 for storing a temperature adjusting agent 62 such as a cold storage agent or a heat retaining agent. As shown in Figs. 14 and 15, in this embodiment, a plurality of storage sections 64 are arranged side by side on the underside of the inner lid 60. The storage section 64 is formed in a bag shape having an opening 64a for inserting and removing the temperature adjusting agent 62. In this embodiment, the opening 64a opens sideways. The storage section 64 has a flap-shaped opening 66 for opening and closing the opening 64a. The opening 66 can keep the opening 64a closed by a detachable part such as a hook-and-loop fastener.

[0038] The first surface 68 facing the article 80 in the storage section 64 has lower air permeability than the second surface 70 different from the first surface 68. In addition, it is preferable that the first surface 68 facing the article 80 in the storage section 64 has lower thermal conductivity than the second surface 70 different from the first surface 68. In the embodiment, the lower surface of the storage section 64 on which the article 80 is placed is the first surface 68, and the side surface connected to the inner lid 60 is the second surface 70. The first surface 68 can be a sheet similar to the skin 30, and for example, a plastic sheet such as polyvinyl chloride, a composite sheet of a plastic sheet and an aluminum vapor deposition film, or a sheet of other material can be used. The second surface 70 is configured to allow air to flow, for example, by using a mesh sheet or a sheet with many holes. In the embodiment, the opening and closing piece 66 is configured of a mesh sheet and has air permeability similar to the second surface 70.

[0039] As shown in Figs. 6 to 8, the heat and cold insulation container 10 includes a base plate 72 arranged at the bottom of the item storage chamber 12a. The base plate 72 includes a hole 74 in which the temperature adjusting agent 62 is arranged. In this embodiment, a plurality of holes 74 penetrating the base plate 72 are formed side by side in the left-right direction (see Fig. 5). The base plate 72 is set to be thicker than the temperature adjusting agent 62. This prevents the temperature adjusting agent 62 arranged in the hole 74 from coming into contact with the item 80 placed on the base plate 72.

[0040] In the thermal insulation / cold storage container 10, the article 80 can be put in and taken out of the article storage chamber 12a by opening only the second lid body 18 (a part of the multiple lid bodies 16, 18). In this way, even if the second lid body 18 is opened, only a part of the opening 14 is opened, so that it is possible to reduce the intrusion of outside air through the opening 14 and the escape of the internal air cooled by the temperature adjusting agent 62 from the opening 14. Therefore, in the thermal insulation / cold storage container 10, even if the frequency of opening and closing of the second lid body 18 increases, it is possible to reduce the temperature change of the article storage chamber 12a. Since the first lid body 16 and the second lid body 18 are hingedly connected to the rear edge of the opening 14 in the container body 12 side by side, both the first lid body 16 and the second lid body 18 can be opened and closed from the front side, which is easy to use. In addition, since the thermal insulation / cold storage container 10 is provided with the inner lid 60, the double structure of the lid body 16, 18 and the inner lid 60 can improve the insulation performance. Since the inner lid 60 is configured to be foldable at the hinge 60a, when inserting or removing the article 80, the inner lid 60 can be folded at the hinge 60a and retracted from above the article 80. In particular, since the hinge 60a extends in the front-rear direction, when the second lid body 18 is opened, the right side portion of the inner lid 60 can be folded toward the unopened first lid body 16, which is convenient to use.

[0041] The thermal insulation / cold insulation container 10 is configured to open and close the opening 14 with a plurality of lids 16, 18, so that the seam between adjacent lids 16, 18 is located above the opening 14. The first lid 16 has a first extension 40 that protrudes toward the lower surface of the second lid 18 adjacent to the first lid 16, so that the first extension 40 covers the lower side of the seam between the first lid 16 and the second lid 18, preventing the seam from becoming a thermal bridge. The second lid 18 has a second extension 44 that protrudes toward the upper surface of the first lid 16 adjacent to the second lid 18, so that the second extension 44 covers the upper side of the seam between the first lid 16 and the second lid 18, preventing the seam from becoming a thermal bridge. In this manner, by covering the seam between adjacent lid bodies 16, 18 from above and below with the first extension portion 40 and the second extension portion 44, the heat insulating performance of the seam between the lid bodies 16, 18 can be improved.

[0042] When the first extension portion 40 abuts against the second lid body 18, the gap between the first extension portion 40 and the second lid body 18 is blocked, so that internal air such as cold air and external air are less likely to pass through the joint between the adjacent lid bodies 16, 18. When the second extension portion 44 abuts against the first lid body 16, the gap between the second extension portion 44 and the first lid body 16 is blocked, so that internal air such as cold air and external air are less likely to pass through the joint between the adjacent lid bodies 16, 18. Since the first extension portion 40 has a first extension portion attachment / detachment portion 40a that is attached and detached to the lower surface of the second lid body 18, the degree of sealing between the first extension portion 40 and the second lid body 18 can be improved. In addition, since the second extension portion 44 has a second extension portion attachment / detachment portion 44a that is attached and detached to the upper surface of the first lid body 16, the degree of sealing between the second extension portion 44 and the first lid body 16 can be improved. By setting the first extension portion 40 so as to span the lid support surface 32, it becomes difficult for internal air such as cold air or external air to pass through the seam between the adjacent lid bodies 16, 18. In addition, by setting the second extension portion 44 to be longer than the upper opening formed by the lid support surface 32, it becomes difficult for internal air such as cold air or external air to pass through the seam between the adjacent lid bodies 16, 18.

[0043] Since the first extending portion 40 has the plate material 42, it is possible to make the first extending portion 40 less likely to bend. This makes it possible to make it difficult for a gap to be formed between the second lid body 18 and the first extending portion 40, and makes it difficult for air in the item storage chamber 12a to pass through the seam between the adjacent lid bodies 16, 18. In addition, since the end of the first extending portion 40 is configured to be supported by the lid support surface 32, it is possible to make it difficult for a gap to be formed between the second lid body 18 and the first extending portion 40, and makes it difficult for air in the item storage chamber 12a to pass through the seam between the adjacent lid bodies 16, 18.

[0044] By arranging the temperature measuring means 48 for measuring the internal temperature of the container body 12 on the inner wall surface on the first lid body 16 side of the container body 12, it is possible to reduce the influence of temperature changes in the item storage chamber 12a caused by opening and closing the second lid body 18.

[0045] The container body 12 of the thermal insulation / cold insulation container 10 has a double structure in which the main body portion 20 is housed in the outer bag 22. The container body 12 has a fall-prevention piece 58 that is connected to the outer bag 22 and is arranged on the inner lower surface of the installation portion 54, and the fall-prevention piece 58 blocks the gap between the outer bag 22 and the lower edge of the installation portion 54 in the main body portion 20, thereby preventing the temperature display means 52 from entering between the main body portion 20 and the outer bag 22 from the installation portion 54. In addition, the container body 12 has a fall-prevention piece 58 that is connected to the outer bag 22 and is arranged on the inner side surface of the installation portion 54, and the fall-prevention piece 58 blocks the gap between the outer bag 22 and the side edge of the installation portion 54 in the main body portion 20, thereby preventing the temperature display means 52 from entering between the main body portion 20 and the outer bag 22 from the installation portion 54.

[0046] In the thermal insulation / cold insulation container 10, the inner lid 60 is provided with a storage section 64 in which a temperature adjusting agent 62 for maintaining the temperature of the item storage chamber 12a is stored. In the storage section 64, a first surface 68 facing the item 80 stored in the item storage chamber 12a has lower air permeability than a second surface 70 different from the first surface 68. In this way, even if the first surface 68 of the storage section 64 contacts the item 80 or is arranged in close proximity to the item 80, adverse effects such as the item 80 being too cold can be prevented. Since the second surface 70 of the storage section 64 that does not face the item 80 has relatively good air permeability, air can pass through the second surface 70 and exchange heat with the temperature adjusting agent 62. Therefore, the temperature of the item storage chamber 12a can be moderately maintained by the temperature adjusting agent 62 stored in the storage section 64.

According to the above-mentioned thermal insulation / cold insulation container, the anti-fall-out piece seals the gap between the main body and the outer bag, thereby preventing the temperature display means from falling out from the installation portion into the gap between the main body and the outer bag.

[0049] In a thermal insulation / cold storage container, when the storage section that contains the ice pack or heat retaining agent is positioned so that it comes into contact with or is placed in close proximity to an item, there is a problem that the item in contact with or close to the storage section may be adversely affected, such as being overcooled or overheated.
