[Embodiment 1]
An embodiment of the present invention will be described in detail below. FIG. 1 is a perspective view showing a schematic configuration of a constant temperature transportation container 10 according to this embodiment.

The constant-temperature transportation container 10 according to the present embodiment has an assembly type configuration capable of constant-temperature transportation of temperature-maintaining articles. As shown in FIG. 1, the constant-temperature transportation container 10 has a rectangular box shape and includes four side wall panels 11, a top panel 12, a bottom panel 13, and a heat storage material P.

The top panel 12 and bottom panel 13 are separable from the four side wall panels 11 and have a rectangular plate shape. Each of the four side wall panels 11 has a rectangular plate shape. The four side wall panels 11 are separable from each other. Here, with respect to the side wall panel 11, the top panel 12, and the bottom panel 13, the luggage compartment A side of the constant temperature transportation container 10 is defined as the inside, and the side opposite to the inside is defined as the outside. Furthermore, in the constant temperature transportation container 10, the top panel 12 side is the upper side, and the bottom panel 13 side is the lower side.

Also, for each panel constituting the constant temperature transport container 10, the direction from the inside to the outside is defined as the thickness direction. Also, in the rectangle of each panel viewed from the outside, the direction of one of two adjacent sides is defined as the vertical direction, and the direction of the other side is defined as the horizontal direction. Taking the side wall panel 11 as an example, in the side wall panel 11 viewed from the outside, of the two adjacent sides, the vertical direction is defined as the vertical direction, and the horizontal direction is defined as the vertical direction. Horizontal direction.

In the constant temperature transportation container 10, each of the four side wall panels 11, the top panel 12 and the bottom panel 13 is composed of a plurality of blocks 1.

The configuration of the side wall panel 11 will be mainly described below. The configuration of the top panel 12 and the bottom panel 13 is the same as that of the side wall panel 11, so the description thereof is omitted.

The side wall panel 11 is configured by arranging and combining a plurality of blocks 1 in both the vertical direction and the horizontal direction on the same plane when viewed from the outside. In the configuration shown in FIG. 1, the side wall panel 11 has a configuration in which sets of two horizontally arranged blocks 1 are vertically stacked in three stages. In addition, in the constant temperature transportation container 10 according to the present embodiment, the arrangement, dimensions, and number of the blocks 1 are not limited to the configuration shown in FIG.

Also, the block 1 is planar. The term “planar” as used herein means a shape that does not have a bent portion. When a plurality of blocks 1 having such a shape are combined, it is possible to configure a side wall panel 11 that configures only one surface. As a configuration different from that in FIG. 1, when the block 1 has a bent portion and is not planar, the bent portion corresponds to the corner of the constant temperature transport container 10. Therefore, the side wall panel in which a plurality of blocks 1 are combined is , constitute at least two sides. Such a planar block 1 may be, for example, a substantially rectangular parallelepiped or substantially cubic block having six rectangular faces. A block 1 shown in FIG. 1 is a substantially rectangular parallelepiped.

In addition, a plurality of blocks 1 are provided with storage portions 4 for storing storage material P, which is a heat storage material. As shown in FIG. 1, the block 1 has an insertion opening 3 for inserting the containing material P and a containing portion 4 . An insertion opening 3 is formed on one side of the two sides of the block 1 when viewed from the outside. The accommodating portion 4 constitutes a space for accommodating the accommodating material P inside the block 1 and extends laterally from the insertion opening 3 . The accommodation portion 4 does not reach the other side surface of the block 1 . In other words, the housing portion 4 is not a cavity passing through the block 1 in the lateral direction. In this way, the block 1 is configured to store the storage material P from the side (horizontal direction).

It should be noted that the accommodating portion 4 may be provided in at least one of the plurality of blocks 1 . In addition, the housing portion 4 may contain a dummy housing material made of a heat insulating material instead of the heat storage material. In the constant-temperature transport container 10, the configuration design of each block 1 can be appropriately set according to the constant-temperature transport environment of the constant-temperature transport container 10 and the like.

In addition, in the constant temperature transportation container 10, the insertion port 3 of the block 1 is closed by the block 1L adjacent to the block 1 concerned. In addition, in the constant-temperature transportation container 10, the block 1 is not limited to such a configuration, and may have a configuration in which a member for closing the insertion port 3 is provided separately.

Further, the storage portion 4 of the block 1 is not limited to the configuration shown in FIG. 1, and is not particularly limited as long as the storage material P can be stored. For example, an insertion opening 3 may be formed on the upper side of the block 1 and the accommodation portion 4 may be a space extending downward from the insertion opening 3 . In this case, the block 1 is configured to accommodate the storage material P from above.

Also, the insertion openings 3 may be formed on both of the two side surfaces of the block 1, and the housing portion 4 may be a cavity penetrating the block 1 in the lateral direction. Even with such a configuration, the two insertion openings 3 can be closed by the blocks 1R and 1L adjacent to the block 1. FIG. Therefore, the accommodating portion 4, which is hollow, can accommodate the accommodating material P. As shown in FIG.

Also, as shown in FIG. 1, preferably, the storage section 4 is provided on the luggage compartment A side (inside) for storing the temperature maintaining article. More specifically, the accommodation portion 4 constitutes a space in the block 1 that is open on the luggage compartment A side. Therefore, the storage material P stored in the storage portion 4 is exposed on the luggage compartment A side. Therefore, the temperature retention in the luggage compartment A is improved.

The constant temperature transport container 10 also has a fitting structure 2 between the block 1 and the block 1L adjacent to the block 1. The fitting structure 2 has a fitting concave portion 2a and a fitting convex portion 2b. The fitting recess 2a is formed in a surface of the block 1 facing the block 1L and is a recess extending in the vertical direction. The fitting projection 2b is formed on the surface of the block 1L facing the block 1, and is a projection extending in the vertical direction. The block 1 and the block 1L are connected so as to form a part of the corner of the constant temperature transportation container 10 by fitting the fitting concave portion 2a and the fitting convex portion 2b. As described above, in the constant temperature transportation container 10, the plurality of blocks 1 have fitting recesses 2a (fitting portions) that fit with the adjacent blocks 1L in the lateral direction.

Also, the block 1R adjacent to the block 1 on the opposite side of the block 1L and the block 1 are connected by means other than fitting. Similarly, the block 1 and the block vertically adjacent to the block 1 are connected by means other than fitting. The connection structure between the adjacent blocks 1 is not limited to the fitting structure 2, and is not particularly limited as long as it is a structure capable of maintaining close contact between the blocks 1 . The blocks 1 may be connected to each other by double-sided tape, adhesive, Velcro (registered trademark), or the like. Further, after the constant temperature transportation container 10 is assembled, the side wall panel 11 may be compressed and connected by winding a stretch film or a PP band from the outside. The double-sided tape may be any known one, and examples thereof include rubber-based, acrylic-based, and silicone-based double-sided tapes. Moreover, the adhesive may be any known one, and examples thereof include epoxy-based, acrylic-based, and urethane-based adhesives.

In the constant temperature transportation container 10 according to the present embodiment, the plurality of blocks 1 are not limited to the configuration shown in FIG. If it is

Next, a method for assembling the constant temperature transportation container 10 will be described. For example, the assembly method is implemented by the following procedures (1) to (3).

(1) A plurality of blocks 1 constituting four side wall panels 11, a top panel 12, and a bottom panel 13 are prepared. (2) In consideration of a constant-temperature transport environment and the like, the storage material P, which is a heat storage material, is stored in a plurality of blocks 1 . (3) A constant-temperature transport container 10 composed of a side wall panel 11, a top panel 12, and a bottom panel 13 is constructed by connecting a plurality of blocks 1 in which the storage material P is stored. The constant temperature transportation container 10 is completed by the procedures (1) to (3).

In this assembling method, if the accommodating portion 4 is a cavity that penetrates the block 1 in the horizontal direction, the accommodating material P may be accommodated collectively after assembling one side wall panel 11 first.

According to the constant temperature transportation container 10 according to the present embodiment, the side wall panel 11, the top panel 12, and the bottom panel 13 are an assembly of a plurality of blocks 1, so the weight of the block 1 loaded with the container P can be reduced to I can do it lightly. Therefore, the handleability of the block 1 is remarkably improved, and it is easy to mount the heat storage material on each panel.

In addition, depending on the type of temperature-retaining goods transported in the constant-temperature transport package, the capacity of the luggage compartment A and the constant-temperature keeping time required for the constant-temperature transport container 10 change. It is very difficult to prepare a constant-temperature transportation container set to the optimum volume of cargo room A and constant-temperature holding time for each type of temperature-maintaining article each time. Since each panel of the constant temperature transport container 10 according to this embodiment is an assembly of a plurality of blocks 1, it is possible to cope with such changes in the volume of the luggage compartment A and the constant temperature holding time. That is, the capacity of the luggage compartment A can be freely changed according to the amount of each type of temperature keeping article. Furthermore, by changing the capacity of the luggage compartment A or the quantity of the storage material P, which is a heat storage material, the constant temperature holding time can be freely changed.

As described above, according to the constant-temperature transportation container 10 according to the present embodiment, the capacity of the luggage compartment A can be freely changed according to the amount of temperature-maintaining articles, and the heat storage material can be easily mounted on each panel. is.

In addition, in the constant-temperature transport container 10 shown in FIG. 1, it is preferable that two of the four side wall panels 11 facing each other have the same block 1 between them. In this case, assembly of the side wall panel 11 is facilitated. Furthermore, by adding or removing blocks 1 from two opposing side wall panels 11, the size of the side wall panel 11 can be easily changed. Therefore, the constant-temperature transportation container 10 in which the capacity of the luggage compartment A can be changed can be easily constructed. For the above reason, it is preferable that the blocks 1 constituting the top panel 12 and the bottom panel 13 facing each other are the same.

In addition, in the constant temperature transport container 10 according to the present embodiment, the sizes of the blocks 1 constituting the two opposing panels may be different.

Here, the materials for the side wall panel 11, top panel 12, and bottom panel 13 are not particularly limited as long as they have heat insulating properties, and foamed plastics and vacuum heat insulating materials are preferably used. Specific examples of foamed plastics include foamed polystyrene, polystyrene/polyolefin composite resin, polyethylene, polypropylene, polyurethane, poly(3-hydroxyalkanoate)-based resin, and the like. Further, from the point of view of excellent heat insulation properties, those containing a radiation heat transfer suppressor are preferable. For example, a carbon-containing bead foam molded product containing carbon that can act as a radiation heat transfer suppressor can be used. Here, carbon includes graphite, graphene, activated carbon, coke, carbon black, and the like. Graphite and carbon black are preferable, and graphite is more preferable, in terms of cost and the effect of improving heat insulating properties. Examples of the vacuum heat insulating material include those using silica powder, glass wool, glass fiber, or the like as a core material.

Furthermore, the constant temperature transportation container 10 may be configured by a combination of two or more types of foamed plastics. Specific examples of such a combination include a combination of a foam obtained by foaming polyethylene and a foam obtained by foaming polystyrene.

Furthermore, the constant temperature transportation container 10 may be configured by a combination of foamed plastic and vacuum insulation. In that case, the outer surface or the inner surface of the heat insulating container X made of foamed plastic is covered with a vacuum heat insulating material, or the vacuum heat insulating material is embedded inside the wall constituting the heat insulating container X, so that the transport container with high heat insulating performance is obtained.

In addition, in the configuration shown in FIG. 1, the top panel 12 and the bottom panel 13 are configured by combining a plurality of blocks 1 . However, the constant temperature transportation container 10 according to this embodiment is not limited to the configuration shown in FIG. For example, the constant temperature transportation container 10 may have a configuration in which the side wall panel 11 is composed of a plurality of blocks 1, while the top panel 12 and the bottom panel 13 are one panel. With this configuration, the capacity of the luggage compartment A can be freely changed in the vertical direction of the constant temperature transportation container 10 .

From the viewpoint of increasing the degree of freedom in changing the capacity of the luggage compartment A, as shown in FIG. , a plurality of blocks 1 . In the configuration shown in FIG. 1, the capacity of the luggage compartment A can be freely changed not only in the vertical direction of the constant temperature transportation container 10 but also in the horizontal direction.

(About heat storage material)
The heat storage material used in this embodiment will be described. The heat storage material referred to here includes the cold storage material in addition to the heat storage material itself. That is, the storage material used in this embodiment includes at least one of a heat storage material and a cold storage material. A heat storage material or a cold storage material is a material in which a heat storage component or a cold storage component is enclosed in a plastic container, a film bag, or the like.

The material of the container or bag filled with the heat storage component or the cold storage component is not particularly limited, and examples include polyethylene, polypropylene, polyethylene terephthalate, polystyrene, polyvinyl chloride, nylon, polyester, etc. One of these materials is selected. It may be used alone, and in order to improve heat resistance and barrier properties, it is also possible to use a multi-layer structure in which two or more of these materials are combined. The shape of the container or bag is not particularly limited, but from the viewpoint of increasing the heat exchange rate, a shape that can secure a large surface area is preferable.

Also, the heat storage material is preferably at least one of a latent heat type heat storage material and a cold storage material. A latent heat-type heat storage material or cold storage material utilizes thermal energy associated with a phase transition of a heat storage component or a cold storage component, and the phase state of the heat storage component or cold storage component changes from a solid state (solid) to a molten state ( The heat energy absorbed during the phase transition from the molten state (liquid) to the solidified state (solid) is utilized.

The solidification/melting temperature of a heat storage component or cold storage component is the temperature at which the phase state changes from a solid state (solid) to a molten state (liquid) or from a molten state (liquid) to a solid state (solid). In the present specification, the "melting temperature" of the cold storage material composition means "the temperature exhibited by the solid cold storage material composition when it melts and liquefies". The above "melting temperature" will be described more specifically with reference to FIG. FIG. 2 shows the temperature of the cold storage material composition when the temperature of the cold storage material composition in the solidified state is placed in the constant temperature tank and then the temperature of the constant temperature tank is raised from a cryogenic temperature at a constant temperature rising rate. It is a graph plotted against time. As shown in FIG. 2, the temperature of the cold storage material composition changes in the following order (1) to (3) as compared with the temperature of the constant temperature bath, which rises at a constant rate: (1) constant; _{( 2} ) _At temperature T1, it hardly changes due to the latent heat of the cold storage material composition, and maintains _a constant temperature from temperature T1 to temperature T2; resume. _In this specification, the temperature T1 is referred to as the "melting start temperature" and the temperature _T2 is referred to as the "melting end temperature". _The temperature T3, which is the midpoint between the temperatures _T1 and T2 _, is defined herein as the "melting temperature".

The phase state generally represents the three phase states of a substance: solid, liquid, and gas. In this embodiment, the solid and liquid phase states are used. The phase state of the heat storage component or the cold storage component refers to a phase state of 50% by weight or more. be.

The composition constituting the latent heat type heat storage component or cold storage component used in the present embodiment is not particularly limited, and for example, WO2014/125878, WO2019/151074, WO2016/068256. , International Publication No. 2019/172260, International Publication No. 2018/180506, etc. can be used.

In the constant-temperature transport container according to the present embodiment, one type of heat storage material and/or cold storage material (one or both of the heat storage material and the cold storage material) may be stored and arranged. When the outside air temperature is lower than the control temperature, such as in winter, the temperature is adjusted to a temperature higher than the solidification/melting temperature of the heat storage material and/or cold storage material to be stored and arranged, and the material in the melted state is arranged. In this case, the temperature of the heat storage material and/or the cold storage material is cooled by the outside air temperature, the temperature is lowered, and thermal energy is released due to the phase transition from the molten state (liquid) to the solidified state (solid). can be suppressed from being exposed to the outside air, and can be maintained within a predetermined temperature range.

On the other hand, when the outside air temperature is higher than the control temperature, such as in the summer, the temperature is adjusted to a temperature lower than the solidification/melting temperature of the heat storage material and/or the cold storage material to be stored, and the material in the solidified state is placed. In this case, the heat storage material and/or the cold storage material are heated by the outside air temperature to raise the temperature, and the temperature is maintained by absorbing thermal energy for the phase transition from the solidified state (solid) to the melted state (liquid). The article can be prevented from being exposed to the outside air, and can be maintained within a predetermined temperature range.

When using one of these heat storage materials and/or cold storage materials, the influence of the temperature rise and decrease due to the temperature difference with the outside air is suppressed by the single heat storage material and/or cold storage material through the heat insulating material that constitutes the constant temperature transportation container. Alternatively, it can be suppressed by the release/absorption action of the latent heat energy possessed by the cold storage material component, and the temperature can be maintained within a predetermined temperature range for a certain amount of time. However, it is necessary to adjust the temperature of the heat storage material and/or the cold storage material in advance to the specified temperature with respect to the external environment temperature, which is complicated. / Weight tends to increase.

Also, in this embodiment, a plurality of heat storage materials having different melting temperature ranges may be used. Two or more types of heat storage materials and/or cold storage materials having different solidifying/melting states can be stored and arranged in the constant-temperature transportation container 10 according to the present embodiment. For example, when using the first heat storage material or cold storage material (a) and the second heat storage material or cold storage material (b) to set the same temperature control conditions throughout the year regardless of the outside temperature, the following are exemplified. A first heat storage material or cold storage material (a) that has a solidification/melting temperature near the control temperature and is in a molten state is used as the heat storage material (hereinafter sometimes referred to as heat storage material P1) that is close to the temperature-maintaining article. , the heat storage material (hereinafter sometimes referred to as heat storage material P2) in the outer peripheral portion of the first heat storage material or cold storage material (a) has a solidification/melting temperature of 0 ° C. or less and is in a solidified state A combination using the second heat storage material or cold storage material (b) is exemplified.

Further, when the first heat storage material or cool storage material (a) and the second heat storage material or cold storage material (b) are used, the first heat storage material or cold storage material (a) is heated to a temperature higher than the control temperature. The second heat storage material or cold storage material (b) may be solidified and frozen at a temperature equal to or lower than the melting temperature of the second heat storage material or cold storage material (b). In this case, the first heat storage material or cold storage material (a) is used for the heat storage material P1 near the temperature holding article, and the second heat storage material or cold storage material (b) is used for the heat storage material P2. Then, the second heat storage material or cold storage material (b) arranged outside the first heat storage material or cold storage material (a) has a temperature resistance to the outside air temperature for maintaining the temperature of the temperature holding article within a desired temperature range. Acts as a thermal buffer.

When two or more types of heat storage materials and/or cold storage materials with different solidification/melting states are used, the influence of the temperature rise and fall due to the temperature difference with the outside air is measured through the heat insulating material that constitutes the container. It can be suppressed by acting as a thermal buffer using the second heat storage material or cold storage material (b) placed outside the first heat storage material or cold storage material (a) arranged adjacent to the first heat storage material or cold storage material (a). Due to the temperature interaction between the cold storage material (a) and the second heat storage material or cold storage material (b), the first heat storage material or cold storage material (a) in the molten state is cooled, the temperature is lowered, and the molten state ( The release of thermal energy to undergo a phase transition from a liquid) to a solid state (solid) can protect the temperature maintaining article from both temperatures above and below that temperature, resulting in a heat storage material or cold storage material. The amount of material used can be reduced, and the temperature-maintaining article can be maintained within a predetermined temperature range for a longer period of time.

When two or more types of heat storage materials and/or cold storage materials with different solidification/melting states are used, as a specific example, a heat storage material or cold storage material whose melting temperature is adjusted to around 5°C or 20°C corresponds to the heat storage material P1. A heat storage material or cold storage material whose melting temperature is adjusted to 0° C. corresponds to the heat storage material P2.

From the viewpoint of versatility of the heat storage material and/or the cold storage material, preferably, the storage material P is a connected body in which a plurality of heat storage materials and/or cold storage materials are connected. As a result, the storage material P can be configured to improve workability during packing and to correspond to a plurality of constant temperature transport containers having different sizes. As a result, the versatility of the containing material P is enhanced.
