2. Description of the Related Art Conventionally, in a high-performance heat-insulating container, a metal layer such as an aluminum vapor deposition layer or an aluminum foil is provided on the exterior part in order to improve the heat insulating property, mainly for the purpose of heat shielding effect. Further, as such a heat insulating container, there is also a container having a vacuum heat insulating material (VIP) including an aluminum vapor deposition layer mainly for ensuring a barrier property.

(Structure of heat insulation container)
The structure of the heat insulating container according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a diagram showing the structure of the heat insulating container according to the present embodiment. FIG. 2 is a diagram showing a state in which each panel of the heat insulating container according to the present embodiment is removed.

As shown in FIG. 1, the heat insulating container 10 according to the present embodiment has a substantially cubic shape or a substantially rectangular parallelepiped shape when assembled, and includes a top surface heat insulating panel 11, a first side surface heat insulating panel 12, and a first side heat insulating panel 12. Six (plural) heat insulating panels 11 to 16 including a two-side heat insulating panel 13, a third side heat insulating panel 14, a fourth side heat insulating panel 15, and a bottom heat insulating panel 16 are provided.

In addition, in this specification, the top heat insulation panel 11, the 1st side heat insulation panel 12, the 2nd side heat insulation panel 13, the 3rd side heat insulation panel 14, the 4th side heat insulation panel 15, and the bottom heat insulation panel 16. May be collectively referred to as heat insulating panels 11 to 16. Further, the first side heat insulating panel 12, the second side heat insulating panel 13, the third side heat insulating panel 14, and the fourth side heat insulating panel 15 may be collectively referred to as side heat insulating panels 12 to 15.

Each of the heat insulating panels 11 to 16 has a main surface (a pair of widest surfaces facing each other, which is the widest of the six surfaces forming each heat insulating panel) having a substantially square shape or a substantially rectangular shape. The top heat insulating panel 11 and the bottom heat insulating panel 16 face each other, and their main surfaces have substantially the same size. The first side heat insulation panel 12 and the third side heat insulation panel 14 are opposed to each other and their main surfaces have substantially the same size. Further, the second side heat insulating panel 13 and the fourth side heat insulating panel 15 face each other and their main surfaces have substantially the same size. Each of the heat insulation panels 11 to 16 is made of a single plate-shaped member having rigidity, and is configured not to be flexibly deformed during use.

The heat insulating container 10 can form a heat insulating space 20 surrounded by six heat insulating panels 11 to 16. Further, the six heat insulating panels 11 to 16 are provided so as to be detachable and assembleable with respect to the other adjacent heat insulating panels 11 to 16, respectively. As a result, the heat insulating container 10 can be changed from an assembled state in which the heat insulating space 20 is formed to a disassembled state in which the heat insulating space 20 is not formed, and a disassembled state to an assembled state. Therefore, when the heat insulating container 10 is not used, the heat insulating container 10 can be stored and transported in a disassembled state in which the heat insulating container 10 is disassembled and piled up.

The heat insulating container 10 is used, for example, in the field of physical distribution for storing and transporting articles that need to be kept cold or warm. In such a heat-insulating container 10, generally, the heat-insulating space 20 capable of accommodating an article is surrounded by the six heat-insulating panels 11 to 16, so that the temperature change inside the heat-insulating container 10 is suppressed as much as possible. Is configured to be.

All of the six heat insulating panels 11 to 16 are heat insulating panels. In this case, the heat insulating panels 11 to 16 are vacuum heat insulating panels, and each has a heat insulating portion 40 including a vacuum heat insulating material 41 as described later (see FIG. 3 ).

In the present embodiment, at least one of the six heat insulating panels 11 to 16 is a radio wave transmitting non-metal panel. Specifically, the top surface heat insulation panel 11 and the bottom surface heat insulation panel 16 facing each other are non-metal panels that transmit radio waves. The non-metal panel is a panel that does not substantially contain metal, and is a panel that transmits radio waves in the thickness direction (direction crossing a pair of main surfaces). In this case, since the top heat insulating panel 11 and the bottom heat insulating panel 16 transmit radio waves, the IC tag arranged in the heat insulating space 20 can be read from the outside of the top heat insulating panel 11 by non-contact communication, for example. On the other hand, the side heat insulation panels 12 to 15 are radio wave impermeable metal panels. The metal panel is a panel that substantially contains metal, and is a panel that does not transmit radio waves in its thickness direction (direction crossing a pair of main surfaces). In this case, since the side heat insulating panels 12 to 15 which are metal panels reflect radio waves, the IC tag 26 (described later) arranged in the heat insulating space 20 is read from the outside of the side heat insulating panels 12 to 15 by non-contact communication. Is practically difficult.

In each drawing, the radio wave non-transmissive non-metal panel is shown in white and the radio wave non-transmissive metal panel is shown in gray in each figure. It should be noted that each non-metal panel and each metal panel may actually be colored in mutually different colors so that the non-metal panel through which radio waves can be visually identified can be specified.

Although the heat insulating container 10 can be assembled and disassembled in the present embodiment, the present invention is not limited to this. Some of the heat insulating panels 11 to 16 may not be assembled and disassembled. For example, the side heat insulation panels 12 to 15 and the bottom heat insulation panel 16 are integrated into a box shape so as not to be disassembled, and the top surface heat insulation panel 11 can be attached to and detached from the box shaped heat insulation panels 12 to 16 like a lid. Is also good.

(Structure of heat insulation panel)
Next, the structure of each of the heat insulation panels 11 to 16 will be further described. In the following, "the heat insulating panels 11 to 16 are parallel (vertical) to a predetermined surface" means "the main surfaces of the heat insulating panels 11 to 16 are parallel (vertical) to the predetermined surface". Means.

The top surface heat insulation panel 11 is a heat insulation panel located on the top surface side (Z direction plus side), and is arranged parallel to the horizontal plane (XY plane). Moreover, the top surface heat insulation panel 11 is arrange|positioned above the side surface heat insulation panels 12-15.

The first side heat insulating panel 12 is a heat insulating panel that is located below the top heat insulating panel 11 and above the bottom heat insulating panel 16 and is parallel to the third side heat insulating panel 14, and is on a horizontal plane (XY plane). In contrast, they are arranged vertically (parallel to the ZX plane). Further, the first side heat insulating panel 12 is arranged vertically to the second side heat insulating panel 13 and the fourth side heat insulating panel 15.

The second side heat insulation panel 13 is a heat insulation panel that is located below the top surface heat insulation panel 11 and above the bottom surface heat insulation panel 16 and is parallel to the fourth side heat insulation panel 15, and is on a horizontal plane (XY plane). In contrast, they are arranged vertically (parallel to the YZ plane). In addition, the second side heat insulating panel 13 is arranged perpendicular to the first side heat insulating panel 12 and the third side heat insulating panel 14.

The third side heat insulating panel 14 is a heat insulating panel that is located below the top heat insulating panel 11 and above the bottom heat insulating panel 16 and is parallel to the first side heat insulating panel 12, and is on a horizontal plane (XY plane). In contrast, they are arranged vertically (parallel to the ZX plane). The third side heat insulating panel 14 is arranged vertically to the second side heat insulating panel 13 and the fourth side heat insulating panel 15.

The fourth side heat insulation panel 15 is a heat insulation panel that is located below the top surface heat insulation panel 11 and above the bottom surface heat insulation panel 16 and is parallel to the second side heat insulation panel 13, and in the horizontal plane (XY plane). In contrast, they are arranged vertically (parallel to the YZ plane). Further, the fourth side heat insulating panel 15 is arranged vertically to the first side heat insulating panel 12 and the third side heat insulating panel 14.

The bottom surface heat insulation panel 16 is a heat insulation panel located on the bottom surface side (negative side in the Z direction), and is arranged parallel to the horizontal plane (XY plane). The bottom heat insulating panel 16 is arranged below the side heat insulating panels 12 to 15.

It is preferable that the thickness of each of the heat insulation panels 11 to 16 is, for example, 5 mm or more and 80 mm or less. In the present embodiment, the case where the heat insulating panels 11 to 16 have the same thickness will be described as an example, but the heat insulating panels 11 to 16 may have different thicknesses.

(Internal structure of heat insulation panel)
Next, the structure of each heat insulation panel 11-16 will be described. FIG. 3 is a cross-sectional view showing the heat insulating portion 40 of each heat insulating panel 11-16. 4A and 4B are cross-sectional views showing the vacuum heat insulating material 41 included in the heat insulating unit 40.

As shown in FIG. 3, the heat insulating section 40 of each of the heat insulating panels 11 to 16 includes a vacuum heat insulating material 41, a foam heat insulating material 42, a heat insulating envelope 43, a heat insulating material protecting member 44, and a heat shield sheet 45. have.

Of these, the vacuum heat insulating material 41 is attached to the foam heat insulating material 42. The vacuum heat insulating material 41 includes a core material 41a and an exterior material 41b provided around the core material 41a. A foamed heat insulating material 42 is arranged on the heat insulating space 20 side of the vacuum heat insulating material 41 (lower side in FIG. 3 ). As a result, it is possible to reduce the risk of the vacuum heat insulating material 41 being damaged when a load placed in the heat insulating space 20 collides with it.

The foam heat insulating material 42 can be disposed adjacent to at least the heat insulating space 20 side of the vacuum heat insulating material 41. A known foamable heat insulating material containing no metal can be used as the foam heat insulating material 42. For example, one or both of a polyurethane foam and a polystyrene foam may be used.

The heat insulation surrounding portion 43 is formed so as to surround the vacuum heat insulating material 41. The heat insulation surrounding portion 43 is arranged on the foam heat insulating material 42 and is fixed to the foam heat insulating material 42. Since the heat insulating enclosure 43 is arranged so as to surround the vacuum heat insulating material 41, the heat insulating performance is improved as compared with the case where the heat insulating enclosure 43 is not arranged. Further, a panel structure in which the vacuum heat insulating material 41 has substantially the same area as the foam heat insulating material 42 and the heat insulating surrounding portion 43 is not used is also possible. In this case, although the heat insulation performance can be further improved, since there is no heat insulation surrounding portion 43, there is a possibility that the vacuum heat insulation material 41 is weak against bag breakage due to intrusion of a sharp object from the side. A slight gap is formed between the heat insulating enclosure 43 and the vacuum heat insulating material 41, so that even if the size of the vacuum heat insulating material 41 changes slightly, the vacuum heat insulating material 41 is removed from the heat insulating outside. It can be accommodated in the enclosure 43. As the heat-insulating surrounding portion 43, a known foamable heat-insulating material containing no metal can be used. For example, one or both of a polyurethane foam and a polystyrene foam may be used.

Further, the heat insulating material protecting member 44 is provided on the heat insulating surrounding portion 43 and mainly plays a role of protecting the vacuum heat insulating material 41. As the heat insulating material protecting member 44, for example, a metal-free organic polymer protecting material can be used.

The heat shield sheet 45 is arranged so as to enclose the entire outer circumference of the vacuum heat insulating material 41, the foam heat insulating material 42, the heat insulating surrounding portion 43, and the heat insulating material protecting member 44. The heat shield sheet 45 can be arranged so as to cover the entire vacuum heat insulating material 41 and the foam heat insulating material 42.

As the heat shield sheet 45, there are a heat shield sheet containing metal (metal heat shield sheet) and a sheet not containing metal (non-metal heat shield sheet). Of these, examples of the heat shield sheet 45 containing a metal include a multilayer sheet containing a metal foil, a vapor deposition sheet in which a vapor deposition layer is formed on one surface of a resin sheet, and the like. As the heat shield sheet 45 containing no metal, for example, a white film type synthetic resin heat shield sheet or the like can be cited.

Next, the vacuum heat insulating material 41 will be further described. As shown in FIG. 4A, the vacuum heat insulating material 41 is composed of a core material 41a and an exterior material 41b having a gas barrier property, and is a heat insulation material obtained by decompressing the interior of the exterior material 41b. FIG. 4B is another example of the vacuum heat insulating material 41. In FIG. 4A, voids are formed at both ends inside the vacuum heat insulating material 41, but in FIG. 4B, voids are not formed. The void may or may not be formed depending on the manufacturing method of the vacuum heat insulating material 41.

As the core material 41a, a material containing no metal, for example, powder such as silica, foam such as urethane polymer, or porous material such as fiber such as glass wool may be used.

The exterior material 41b is a member that covers the periphery of the core material 41a, and a flexible sheet in which a core material, a heat-welding layer, and a gas barrier layer are sequentially laminated may be used. As the gas barrier layer, there are a gas-containing layer (metal gas barrier layer) and a metal-free layer (non-metal gas barrier layer). Among these, examples of the gas barrier layer containing a metal (metal gas barrier layer) include a metal foil or a vapor deposition sheet having a metal vapor deposition layer formed on one surface of a resin sheet. Aluminum can be used for the metal foil, for example. As the metal vapor deposition layer, for example, aluminum or aluminum oxide can be used. Examples of the gas barrier layer containing no metal (non-metal gas barrier layer) include a vapor deposition sheet in which a non-metal vapor deposition layer is formed on one surface of a resin sheet. As the non-metal vapor deposition layer, for example, an inorganic oxide such as silicon oxide can be used.

The exterior material 41b of the vacuum heat insulating material 41 or the heat shield sheet 45 preferably has a structure that does not transmit visible light. As a result, it is possible to prevent the core material 41a from being deteriorated by the irradiation of visible light.

As described above, at least one of the six heat insulating panels 11 to 16 of the heat insulating container 10 is a radio wave transmitting non-metal panel. Specifically, each of the top heat insulating panel 11 and the bottom heat insulating panel 16 is a radio wave transmitting non-metal panel. A non-metal panel is a panel that is substantially free of metallic elements. For example, when the non-metal panel having the configuration shown in FIGS. 3 and 4 is used, the vacuum heat insulating material 41, the foam heat insulating material 42, the heat insulating surrounding portion 43, the heat insulating material protecting member 44, and the heat shield sheet 45 are all It is preferable that no metal be included.

On the other hand, of the six heat insulating panels 11 to 16 of the heat insulating container 10, the heat insulating panels except the non-metal panel are metal panels that are impermeable to radio waves. Specifically, each of the side heat insulating panels 12 to 15 is a radio wave impermeable metal panel. A metal panel is a panel of which at least some elements are metal elements. For example, when the metal panel having the structure shown in FIGS. 3 and 4 is used, any one of the vacuum heat insulating material 41, the foam heat insulating material 42, the heat insulating surrounding portion 43, the heat insulating material protecting member 44, and the heat shield sheet 45 is used. , Preferably including metal elements. In particular, it is preferable that a part or all of the exterior material 41b of the vacuum heat insulating material 41 and the heat shield sheet 45 include a metal element.

Note that all of the six heat insulation panels 11 to 16 do not necessarily have to be vacuum heat insulation panels. Part or all of the heat insulating panels 11 to 16 may be panels including a foam heat insulating material such as polyurethane foam and polystyrene foam. For example, the top heat insulating panel 11 and the bottom heat insulating panel 16 may be panels including a foaming heat insulating material, and the side heat insulating panels 12 to 15 may be vacuum heat insulating panels.

(Operation of the present embodiment)
Next, the operation of the present embodiment having such a configuration will be described.

First, as shown in FIG. 5, the side heat insulating panels 12 to 15 and the bottom heat insulating panel 16 are assembled in a box shape, and the contents 25 with an IC tag are housed therein. The content 25 with an IC tag has an IC tag 26 on its outer surface.

The IC tag 26 is also called a non-contact IC tag, an RFID (Radio Frequency Identification) tag, an RF tag, or the like, and is a microminiature communication terminal in which an IC chip and a wireless antenna are sealed with resin or glass to form a tag shape. Is. The IC tag 26 recognizes and displays the information recorded in the IC chip by recording predetermined information in the IC chip, attaching the tag to the object, and reading the recorded information by the reading device 35 side by wireless communication. It is a thing. As the IC tag 26, there are an active type that has a built-in power source (active type) and a passive type that does not have a built-in power source (passive type), but it is preferable to use the passive type. Further, the IC tag 26 may be an electromagnetic induction system that uses a frequency band of 135 kHz or 13.56 MHz depending on a communication frequency to be used, and a radio wave that uses a frequency band of UHF (900 MHz) band or 2.45 GHz. It may be a system. The IC tag 26 may be located inside the content 25 with the IC tag.

After the contents 25 with the IC tag are accommodated in the box-shaped side heat insulating panels 12 to 15 and the bottom heat insulating panel 16, the top heat insulating panel 11 is mounted on the side heat insulating panels 12 to 15 and hermetically sealed. In this way, the heat-insulating container 30 including the heat-insulating container 10 having the heat-insulating panels 11 to 16 and the content 25 with the IC tag housed in the heat-insulating container 10 can be obtained. In the present embodiment, such a heat insulating container 30 containing contents is also provided.

Then, the information stored in the IC tag 26 of the content 25 with the IC tag is read by using the reading device 35 such as a reader/writer. The reading device 35 is arranged at a position facing the top heat insulating panel 11 which is a radio wave transmitting non-metal panel. In this case, since radio waves pass through the top heat insulation panel 11, wireless communication is performed between the IC tag 26 and the reading device 35 (see arrow C1 in FIG. 5), and the reading device 35 causes the IC chip of the IC tag 26 to be used. The data recorded in can be recognized.

The side heat insulation panels 12 to 15 are each a radio wave non-transmissive metal panel. Therefore, the reflectivity of radio waves inside the side heat insulation panels 12 to 15 is enhanced, and the communication characteristics in the direction of passing through the top heat insulation panel 11 can be improved.

Since the side heat insulating panels 12 to 15 are radio wave impermeable metal panels, if the reading device 35 is opposed to any of the side heat insulating panels 12 to 15, the side heat insulating panels 12 to 15 are connected to the IC tag 26. It is practically difficult to perform wireless communication in (see arrows C2 and C3 in FIG. 5).

As described above, according to the present embodiment, at least one heat insulating panel among the plurality of heat insulating panels 11 to 16 is a radio wave transmitting non-metal panel. Thereby, the information of the IC tag 26 arranged inside the heat insulating container 10 is directly read from the outside of the heat insulating container 10 while maintaining the heat insulating property, the heat insulating property, and the airtight property of the heat insulating space 20 by the heat insulating panels 11 to 16. It becomes possible.

Further, according to the present embodiment, at least one heat insulating panel among the plurality of heat insulating panels 11 to 16 is a radio wave impermeable metal panel. As a result, the metal panel functions as a radio wave reflection surface, and the reflectivity of radio waves from the IC tag 26 can be enhanced. As a result, the information of the IC tag 26 can be easily read outside the non-metal panel, and the reading probability (efficiency) of the IC tag 26 by the reading device 35 can be improved. In general, a metal panel has higher heat insulating properties and heat shielding properties than a non-metal panel. Therefore, by making a part of the heat insulating panels metal panels, it is possible to prevent the heat insulating property and the heat insulating property of the heat insulating container 10 from being lowered. it can.

Further, according to the present embodiment, the two heat insulating panels (top heat insulating panel 11 and bottom heat insulating panel 16) facing each other out of the plurality of heat insulating panels 11 to 16 are non-metal panels, respectively, and other heat insulating panels. Each of the panels (side heat insulating panels 12 to 15) is a metal panel. In this case, the reading direction of the IC tag 26 by the reading device 35 coincides with the normal direction of the main surface of the non-metal panel. On the other hand, it is practically difficult to read the information of the IC tag 26 from the normal direction of the main surface of the metal panel. In this way, the reading direction of the IC tag 26 by the reading device 35 can be limited so that the information of the IC tag 26 can be read only from a specific direction. Specifically, in the present embodiment, the top heat insulating panel 11 and the bottom heat insulating panel 16 are each a non-metal panel, and the plurality of side heat insulating panels 12 to 15 are each a metal panel. In this case, the reading direction of the IC tag 26 by the reading device 35 is made to coincide with the normal direction (Z direction) of the main surfaces of the top heat insulating panel 11 and the bottom heat insulating panel 16, and the other directions (X direction and Y direction). From this, it becomes substantially difficult to read the information of the IC tag 26. In addition, since the plurality of side heat insulating panels 12 to 15 are each a metal panel, even when another heat insulating container 10 is arranged around the heat insulating container 10, the interference by the IC tag of the other heat insulating container 10 is caused. Can be suppressed.

Further, according to the present embodiment, the metal panel has the core material 41a and the gas barrier layer containing the metal that covers the periphery of the core material 41a. Can be suppressed.

Further, according to the present embodiment, the non-metal panel has the core material 41a and the gas barrier layer that does not include a metal that covers the periphery of the core material 41a, so that the non-metal panel can secure the gas barrier property and the radio wave. Are transparent to non-metallic panels.

(Modification 4)
FIG. 9 is a diagram showing a combination 50 of a plurality (three) of heat insulation containers according to the fourth modification. In FIG. 9, the heat insulating container combination 50 includes a first heat insulating container 10A, a second heat insulating container 10B, and a third heat insulating container 10C. The first heat insulating container 10A, the second heat insulating container 10B, and the third heat insulating container 10C (collectively referred to as heat insulating containers 10A to 10C) are respectively a top heat insulating panel 11, a bottom heat insulating panel 16, and a plurality of heat insulating containers. Side insulation panels 12 to 15 and a plurality of insulation panels 11 to 16. For example, the first heat insulating container 10A stores frozen contents, the second heat insulating container 10B stores cold contents, and the third heat insulating container 10C stores normal temperature contents. May be done.

In FIG. 9, the heat insulating panels 11 to 16 of the first heat insulating container 10A and the second heat insulating container 10B each include a radio wave permeable non-metal panel and a radio wave opaque metal panel. In this case, the disposition positions of the non-metal panel and the metal panel of the first heat insulating container 10A and the disposition position of the non-metal panel and the metal panel of the second heat insulating container 10B are different from each other. That is, in the first heat insulating container 10A, the top heat insulating panel 11 and the bottom heat insulating panel 16 are each a non-metal panel, and the side heat insulating panels 12 to 15 are each a metal panel. In the second heat insulating container 10B, the side heat insulating panels 12 and 14 facing each other are non-metal panels, and the top heat insulating panel 11, the side heat insulating panels 13, 15 and the bottom heat insulating panel 16 are each metal panels. The heat insulation panels 11 to 16 of the third heat insulation container 10C are all made of metal panels.

As described above, the arrangement relationship between the non-metal panel and the metal panel is different between the heat insulating containers 10A to 10C. As a result, the first reading device 35A arranged on the top heat insulating panel 11 side can read the information of the IC tag 26 housed in the first heat insulating container 10A. On the other hand, the first reading device 35A cannot read the information of the IC tags 26 housed in the second heat insulating container 10B and the third heat insulating container 10C. Further, the second reader 35B arranged on the side heat insulating panel 12 side can read the information of the IC tag 26 housed in the second heat insulating container 10B. On the other hand, the second reading device 35B cannot read the information of the IC tags 26 housed in the first heat insulating container 10A and the third heat insulating container 10C.

In this way, the first reader 35A and the second reader 35B selectively utilize the IC tags 26 of the specific heat insulating containers 10A and 10B by utilizing the differences in the radio wave transmission directions of the individual heat insulating containers 10A to 10C. Can be read. This suppresses interference from the IC tags 26 of the heat-insulating containers 10A to 10C that are not to be read, and prevents the first reading device 35A and the second reading device 35B from reading the IC tags 26 that are not to be read by mistake. You can In addition, for example, it is possible to detect that the contents to be stored in the first heat insulating container 10A are mistakenly stored in the second heat insulating container 10B. This makes it possible to find the contents contained in the wrong heat insulating container, and prevent the contents from being conveyed while being contained in the wrong heat insulating container.

Further, in FIG. 9, each non-metal panel and each metal panel of the heat insulating containers 10A to 10C may be colored in different colors so that the non-metal panel through which radio waves can be visually identified can be specified.

Furthermore, the arrangement of the radio wave-transmissive non-metal panel of the heat insulating container may be changed so that the direction of communication is changed for each reading device that reads radio waves of different frequency bands. Examples of the frequency band include any of the 2.4 GHz band, 900 MHz band, 135 kHz band, and the like. By placing the contents with IC tags corresponding to these different frequency bands in a heat insulating container in which a non-transparent non-metallic panel corresponding to a predetermined frequency band is placed, a fixed direction for each different frequency band is determined. The IC tag can be read from, and it is possible to prevent erroneous detection of other heat insulating containers.

Further, the second side heat insulating panel 13 of the second heat insulating container 10B and the fourth side heat insulating panel 15 of the third heat insulating container 10C are connected by the connecting member 27.

In this case, the orientation of the radio wave transmitting non-metal panel of the heat insulating containers 10A to 10C and the arrangement of the heat insulating containers 10A to 10C can be fixed. As a result, it is possible to prevent mistakes that the heat insulating containers 10A to 10C are placed in the wrong positions or the orientations of the non-metal panels of the heat insulating containers 10A to 10C are mistaken. Further, for example, when the contents of different temperature zones are stored in the heat insulating containers 10A to 10C, the contents of a plurality of temperature zones that should be delivered to the same place are not lost, and the mistake of the temperature zone and the IC tag 26 It is possible to prevent the reading direction from being mistaken. Furthermore, when the heat insulating containers 10A to 10C are detachably fixed by the connecting member 27, when the heat insulating containers 10A to 10C are individually used (for example, use as a cool box), the heat insulating containers 10A to 10C are connected and used. You can freely switch between cases. As a result, the degree of freedom in use of the heat insulating containers 10A to 10C is increased, and the required number of heat insulating containers 10A to 10C can be reduced.
