Further, in the constant temperature storage transport container 100, the upper surface of the bottom plate portion 31 is provided with only the storage material 52 which is a heat storage material, or the storage recess 32 which can store the storage material 53 and dry ice.

Next, a method of assembling the constant temperature storage transport container 100 will be described. In the method of assembling the constant temperature storage transport container 100, the rectangular plate material constituting the closed side wall portion 41 is finally assembled. When unpacking the constant temperature storage transport container 100, first, the top plate portion 11 is unpacked. Next, the side wall portion 21, the side wall portion 22, and the facing side wall portion 42 are unpacked, and finally the closed side wall portion 41 is unpacked.

First, the rectangular plate material forming the top plate portion 11, the rectangular plate material forming the side wall portions 21 and 22, and the rectangular shape forming the bottom plate portion 31 by the horizontal uneven fitting portion and the vertical uneven fitting portion. The plate material and the rectangular plate material constituting the facing side wall portion 42 are fitted to assemble the container body X. The order of fitting of the rectangular plate members constituting the container main body X can be appropriately set according to the formed portions of the horizontal uneven fitting portion and the vertical uneven fitting portion.

Next, the constant temperature storage transport container 100 is completed by assembling the rectangular plate material constituting the closed side wall portion 41 by fitting the container body X thus assembled. At this time, the lower ends of the vertical ridges 41a formed at both end portions of the closed side wall portion 41 are formed on both the side wall portion 21 side and the side wall portion 22 side in the notch portion 12 of the top plate portion 11, respectively. A rectangular plate material constituting the closed side wall portion 41 is installed so as to be inserted into the vertical concave groove 11a. Then, in this state, by moving the rectangular plate material constituting the closed side wall portion 41 in the vertical downward direction, the vertical convex strip 41a passes through the vertical concave groove 11a of the top plate portion 11 and the vertical concave portion of the side wall portion 21. The vertical concave groove formed in the groove 21a and the side wall portion 22 is slid. Then, the horizontal ridge 41b of the closed side wall portion 41 is fitted into the horizontal concave groove 31a of the bottom plate portion 31, so that the closed side wall portion 41 is assembled in the container body X.

As described above, in the constant temperature storage transport container 100, with respect to the top plate portion 11 and the closed side wall portion 41 adjacent to each other, the top plate portion so that the closed side wall portion 41 slides between the outside and the inside of the top plate portion 11. A sliding fitting portion is formed between the 11 and the closed side wall portion 41. This sliding fitting portion is composed of a ridge and a concave groove, and is configured so that the ridge can slide in the concave groove.

More specifically, the ridges in the sliding fitting portion are vertical ridges 41a formed at both end portions of the closed side wall portion 41. Further, the concave groove in the sliding fitting portion includes a vertical concave groove 11a formed on the side wall portion 21 side in the notch portion 12, a vertical concave groove 21a in the side wall portion 21, and a side wall portion 22 in the notch portion 12. It is composed of a vertical concave groove 11a formed on the side and a vertical concave groove formed on the side wall portion 22. The vertical concave groove 11a formed on the side wall portion 21 side in the notch portion 12 and the vertical concave groove 21a of the side wall portion 21 are connected to each other. Further, the vertical concave groove 11a formed on the side wall portion 22 side in the notch portion 12 and the vertical concave groove formed on the side wall portion 22 are connected to each other. Therefore, the closed side wall portion 41 slides between the outside and the inside of the top plate portion 11 by the sliding fitting portion configured as described above. Since the sliding fitting portion is provided in this way, the constant temperature storage transport container 100 can be opened and closed only by sliding the closed side wall portion 41, and the convenience is improved.

Further, according to the configuration of the constant temperature storage and transportation container 100, the opening and closing operation of the constant temperature storage and transportation container 100 can be simplified as compared with the configuration in which the container main body is closed by the top plate portion. Therefore, it is possible to easily store the temperature-controlled article that requires low-temperature storage in the constant-temperature storage transport container 100 by shortening the time for exposing the article to the outside air. In the configuration in which the container body is closed by the top plate portion, (a) the bottom plate portion is installed and then the temperature-controlled article is placed, (b) the side wall portions are arranged on three sides to accommodate the temperature-controlled article, or (C) The temperature-controlled article is stored in the constant-temperature storage transport container by any of the methods of storing the temperature-controlled article from the rear top surface after assembling the bottom plate portion and the side wall portion. Regardless of which method (a) to (c) is used to accommodate the temperature-controlled article, the time for the temperature-controlled article to come into contact with the outside air becomes long.

In the above configuration, the convex strip (vertical convex strip 41a) constituting the sliding fitting portion is formed on the closed side wall portion 41, while the concave groove (vertical) constituting the sliding fitting portion is formed. The concave groove 11a, the vertical concave groove 21a, etc.) were formed in the top plate portion 11 and the side wall portions 21 and 22. However, the positions where the ridges and grooves are formed may be any position as long as they can be fitted to each other to form a sliding fitting portion. For example, the ridges constituting the sliding fitting portion are formed on the top plate portion 11 and the side wall portions 21 and 22, and the concave groove constituting the sliding fitting portion is formed on the closed side wall portion 41. May be.

Here, in the constant temperature storage and transportation container 100 according to the present embodiment, an insertion groove 33 for inserting a forklift claw is formed in a bottom plate portion 31 which is one of the constituent members of the constant temperature storage and transportation container 100. There is. The term "forklift claw" as used herein means a fork-shaped lift claw that holds a container and is provided in a device that transports and stores the container by raising and lowering it. Therefore, "forklift claws" also include handlift claws. FIG. 4 is a diagram showing a schematic configuration of a bottom plate portion 31 of a constant temperature storage transport container 100. FIG. 4A is a side view of the bottom plate portion 31 as viewed from the Y direction. FIG. 4B is a side view of the bottom plate portion 31 as viewed from the X direction. FIG. 4 (c) is a top view of the bottom plate portion 31 as viewed from above. FIG. 4D is a bottom view of the bottom plate portion 31 as viewed from below.

As shown in FIGS. 4A to 4D, two insertion grooves 33 are formed on the lower surface of the bottom plate portion 31. The two insertion grooves 33 extend from one end to the other end of the bottom plate portion 31 in the Y direction so as to be parallel to each other. Further, since the insertion groove 33 is formed, the bottom plate portion 31 is in contact with the ground in a part of the bottom surface. As shown in FIG. 4D, the ground contact surface 35 in the bottom plate portion 31 in contact with the ground is a part of the bottom surface of the bottom plate portion 31.

The insertion groove 33 may be formed, for example, when the rectangular plate material constituting the bottom plate portion 31 is manufactured before assembling the constant temperature storage transport container 100. For example, a rectangular plate material constituting the bottom plate portion 31 in which the insertion groove 33 is formed can be manufactured by cutting, integrally molding, bonding a rectangular member to the rectangular plate material by adhesion, or the like. Therefore, in the configuration in which the insertion groove 33 is formed in the bottom plate portion 31, the existing forklift pallet or handlift pallet is used in the manufacturing process of the bottom plate portion 31 (for example, the existing forklift). A configuration in which a pallet for a hand lift or a pallet for a hand lift and a molded product constituting the bottom plate portion 31 are fixed by a fixing means or the like) cannot be included.

As described above, the constant temperature storage transport container 100 includes a bottom plate portion 31 in which an insertion groove 33 for inserting a forklift claw is formed. Therefore, at the time of cargo handling work by the forklift, the user inserts the claws of the forklift into the insertion groove 33 of the bottom plate portion 31 and transports the constant temperature storage transport container 100. That is, it is not necessary to separately prepare a forklift pallet for the cargo handling work of the constant temperature storage transport container 100. Therefore, it is not necessary to design the dimensions of the constant temperature storage transport container 100 according to the dimensions of the forklift pallet. Further, for the cargo handling work by the forklift, the bottom plate portion 31 is placed on the forklift pallet, and the step of fixing the constant temperature storage transport container 100 and the forklift pallet is not required, and the forklift pallet is fixed to the bottom plate portion 31. The process of cargo handling work can be simplified without the need for a process to be performed. Further, since the forklift pallet is not required, the load applied to the forklift can be reduced. In particular, when the bottom plate portion 31 is made of foamed plastic, the effect of reducing the load applied to the forklift is remarkable. Further, since the pallet-shaped portion of the bottom plate portion 31, that is, the insertion groove 33 forming portion is made of a heat insulating material, the heat insulating performance of the constant temperature storage transport container 100 is improved.

From the above, by using the constant temperature storage transport container 100, the degree of freedom in container design is not affected by the transport pallet, and the workability of cargo handling work by the forklift is improved. The number and dimensions of the insertion grooves 33 can be appropriately set according to the dimensions of the constant temperature storage transport container 100, the dimensions of the forklift claws inserted into the insertion grooves 33, and the like.

Further, in the constant temperature storage transport container 100, the insertion groove 33 includes a protective member 34 (first protective member) provided on the inner wall surface thereof. The protective member 34 is provided on the wall surface constituting the insertion groove 33, and is composed of a plurality of protective sheets 34a. The protective sheet 34a is uniformly provided on the side wall surface and the bottom wall surface of the insertion groove 33, for example, by adhesion with an adhesive or double-sided tape. The protective member 34 has a role of protecting the insertion groove 33 from the claws of the forklift when the constant temperature storage transport container 100 is transported by the forklift. Therefore, since the protective member 34 is provided in the insertion groove 33, it is possible to prevent the insertion groove 33 from being damaged, and the load of the constant temperature storage transport container 100 and the article subject to temperature control is also dispersed. It is possible to reduce the biting of the insertion groove 33 itself due to the forklift. In particular, when the bottom plate portion 31 is made of foamed plastic, the strength of the bottom plate portion 31 is weak, so that the protective effect of the protective member 34 is effective.

The material of the protective member 34 is not particularly limited as long as it can protect the forklift claws. For example, examples of the material of the protective member 34 include a hard resin material such as polypropylene and polyethylene, an elastic material such as rubber, and a combination of these materials. Further, from the viewpoint of reducing the weight of the constant temperature storage transport container 100, the hard resin material is preferably a foamed resin or a slightly foamed resin.

Further, the insertion groove 33 is not particularly limited in the extending direction as long as the forklift claw can be inserted. More preferably, the insertion groove 33 has a configuration extending in a plurality of directions. As a result, the forklift claws can be inserted in the extending direction of the insertion groove 33, so that the forklift claws can be efficiently aligned with the bottom plate portion 31 of the constant temperature storage transport container 100 with respect to the insertion groove 33. It can be combined and the efficiency of cargo handling work is improved.

FIG. 5 is a diagram showing a configuration example of a bottom plate portion 31A in which an insertion groove 33A extending in a plurality of directions is formed. FIG. 5A is a side view of the bottom plate portion 31A as viewed from the Y direction. FIG. 5B is a side view of the bottom plate portion 31A as viewed from the X direction. FIG. 5C is a top view of the bottom plate portion 31A as viewed from above. FIG. 5D is a bottom view of the bottom plate portion 31A as viewed from below.

As shown in FIGS. 5A to 5D, the insertion groove 33A is composed of a groove 33B and a groove 33C. Two grooves 33B and 33C are formed on the lower surface of the bottom plate portion 31A, respectively. The groove 33B extends from one end of the lower surface of the bottom plate portion 31A in the Y direction to the other end, while the groove 33C extends from one end of the lower surface of the bottom plate portion 31A in the X direction to the other end. Further, the groove 33B and the groove 33C intersect with each other.

Further, by forming the insertion groove 33A composed of the grooves 33B and 33C in this way, the bottom plate portion 31 is in contact with the ground in a part of the bottom surface. As shown in FIG. 5D, the ground contact surface 35A in the bottom plate portion 31 in contact with the ground is a part of the bottom surface of the bottom plate portion 31.

With such a configuration, the insertion groove 33A can be inserted with a forklift claw for transporting or a transporting device from each direction of the grooves 33B and 33C. Therefore, the insertion groove 33A has a shape that allows insertion from four directions, so that cargo handling work is streamlined.

In the constant temperature storage transport container 101, the top plate portion 14 and the bottom plate portion 31 are fitted to the side wall portions 22 and 23 and the upper end portions and the lower end portions of the opposite side wall portions 42 by horizontal uneven fitting portions (not shown). Then, the side wall portions 22 and 23 and the adjacent side wall portions in the opposite side wall portion 42 are fitted by a vertical uneven fitting portion (not shown). Further, the closed side wall portion 43 is fitted with the top plate portion 14 and the bottom plate portion 31 by inserting the horizontal ridge 43a into the horizontal concave groove formed in the top plate portion 14 and the bottom plate portion 31. Further, the closed side wall portion 43 fits into the side wall portion 22 by inserting the vertical convex strip 43b into the horizontal concave groove 31a into the vertical concave groove (not shown) formed in the side wall portion 22. Therefore, the inside of the constant temperature storage transport container 100 is a closed space.

In the constant temperature storage transport container 101, the configuration of the sliding fitting portion described above is different from the configuration shown in FIGS. 1 to 3. The above-mentioned sliding fitting portion may be configured such that one of the two side wall portions adjacent to each other slides between the outside and the inside of the other side wall portion. In the constant temperature storage transport container 101, among the side wall portions 24 and the closed side wall portions 43 adjacent to each other, the top plate portion 14 and the bottom plate portion so that the closed side wall portion 43 slides between the outside and the inside of the side wall portion 24. A sliding fitting portion is formed between the container and the 31. This sliding fitting portion is composed of a ridge and a concave groove, and is configured so that the ridge can slide in the concave groove. Further, the length of the side wall portion 24 in the Y direction is shorter than the length of the side wall portion 21 in the Y direction by the thickness of the closed side wall portion 43.

More specifically, the ridges in the sliding fitting portion are horizontal ridges 43a formed on the facing surfaces of the closed side wall portion 43 with the top plate portion 14 and the bottom plate portion 31. Further, the concave groove in the sliding fitting portion is a horizontal concave groove formed on a surface of the top plate portion 14 and the bottom plate portion 31 facing the closed side wall portion 43, which is not shown. The closed side wall portion 43 slides between the outside and the inside of the side wall portion 24 by the sliding fitting portion configured as described above. Since the sliding fitting portion is provided in this way, the constant temperature storage transport container 101 can be opened and closed only by sliding the closed side wall portion 43, and the convenience is improved. In particular, when the size of the constant temperature storage transport container 100 is extremely large, for example, when the height is larger than the height of a person, the opening / closing operation of the constant temperature storage transport container 100 becomes simpler than the configuration in which the container body is closed by the top plate portion. ..

(About storage materials 51 and 52, which are heat storage materials)
The heat storage material (also referred to as a cold storage material) in the storage materials 51 and 52 is a material in which a heat storage component (also referred to as 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 is not particularly limited, and examples thereof include polyethylene, polypropylene, polyethylene terephthalate, polystyrene, polyvinyl chloride, nylon and polyester, and one of these materials is used alone. However, in order to enhance heat resistance and barrier properties, it is also possible to use a multi-layered structure in which two or more of these materials are combined. The shape of the container or bag is not particularly limited, but a shape that can secure a large surface area is preferable from the viewpoint of increasing the heat exchange rate.

Further, the storage materials 51 and 52 are preferably latent heat storage materials. The latent heat storage material utilizes the thermal energy associated with the phase transition of the heat storage component, and is absorbed when the phase state of the heat storage component changes from the solidified state (solid) to the molten state (liquid). It utilizes the thermal energy generated or the thermal energy released during the phase transition from the molten state (liquid) to the solidified state (solid).

The solidification / melting temperature of the heat storage component is a temperature at which the phase state changes from a solidified state (solid) to a molten state (liquid) or from a molten state (liquid) to a solidified state (solid). In this embodiment, a differential scanning calorimeter (for example, manufactured by Seiko Instruments Co., Ltd .: SII EXSTAR6000 DSC) is used to measure at a heating rate of 2 ° C./min, and the peak temperature values of the obtained chart (provided that there are a plurality of values). If there is a peak of, the value of the maximum peak temperature) is defined as the solidification / melting temperature.

The phase state generally represents three phase states of a substance, solid, liquid, and gas, but in the present embodiment, the solid and liquid phase states are used. The phase state of the heat storage component refers to a phase state of 50% by weight or more, and for example, a phase state in which 80% by weight of the heat storage component is in a solid state and 20% by weight is in a liquid state is a solid state (solidification state).

The composition constituting the latent heat storage component used in the present embodiment is not particularly limited, and is, for example, sodium sulfate / 10hydrate, sodium acetate / trihydrate, potassium chloride / hexahydrate. Inorganic hydrate salts such as quaternary ammonium salts and hydrates, normal tetradecane, normal hexadecane, normal heptadecane, normal dodecane, normal docosan and other linear and branched paraffins with 9 to 30 carbon atoms. Saturated fatty acids having 6 to 18 carbon chains such as at least one higher alcohol, octanoic acid, decanoic acid, lauric acid, dodecanoic acid, stearic acid, etc. selected from the group, methyl laurate, methyl myristate, butyl stearate, etc. Fatty acid ester compounds such as palmitoleic acid, oleic acid, linoleic acid, unsaturated fatty acids having 6 to 18 carbon chains and their ester compounds, 1-decanol, 2-decanol, undecanol, lauryl alcohol, tridecanol, myristyl alcohol, penta. High-grade monohydric alcohols having 6 or more carbon atoms such as decanol, cetyl alcohol, heptadecanol, stearyl alcohol, nonadecanol, araquil alcohol, behenyl alcohol, carnauvir alcohol, ceryl alcohol, erizyl alcohol, and l-menthol. Organic compound heat storage material compositions such as polyalkylene glycols, which are dihydric alcohols such as alcohols (including linear alcohols, branched alcohols, primary alcohols, secondary alcohols and tertiary alcohols), polyethylene glycols and polybutylene glycols. As mentioned, one kind or a mixture of two or more kinds can also be used.

In addition, those containing water as a main component such as potassium hydrogen carbonate aqueous solution, potassium chloride aqueous solution, ammonium chloride aqueous solution, sodium chloride aqueous solution, calcium chloride aqueous solution, calcium bromide aqueous solution, etc., and those containing water and a highly water-absorbent polymer are mentioned. Be done.

A heat storage material made of one kind can be stored and arranged in the constant temperature storage and transportation container 100 according to the present embodiment. When the outside air temperature is lower than the desired temperature-controlled article such as in winter, the temperature is adjusted at a temperature higher than the solidification / melting temperature of the heat storage material to be stored and placed, and the one in the melted state is placed. In this case, the heat storage material is cooled by the outside air temperature to lower the temperature, and heat energy is released for the phase transition from the molten state (liquid) to the solidified state (solid), so that the article subject to temperature control is exposed to the outside air. It can be suppressed and maintained within a predetermined temperature range.

On the other hand, when the outside air temperature is higher than the desired temperature-controlled article such as in summer, the temperature is adjusted at a temperature lower than the solidification / melting temperature of the heat storage material to be stored and arranged, and the one in the solidified state is arranged. In this case, the heat storage material is heated by the outside air temperature to raise the temperature, and the heat energy is absorbed for the phase transition from the solidified state (solid) to the melted state (liquid), so that the article subject to temperature control is exposed to the outside air. Exposure can be suppressed and maintained within a predetermined temperature range.

When a heat storage material composed of these one type is used, the latent heat energy of a single heat storage material component has the influence of temperature rise and fall due to the temperature difference with the outside air through the heat insulating material constituting the constant temperature storage transport container 100. It can be suppressed by the release / absorption action of, and can be maintained within a predetermined temperature range for a certain period of time. However, it is necessary to adjust the heat storage material to a specified temperature in advance with respect to the external environmental temperature, which is complicated, and the quantity / weight of the heat storage material used tends to increase in order to maintain the temperature for a long time. ..

In the constant temperature storage transport container 100 according to the present embodiment, two or more types of heat storage materials having different solidification / melting states can be stored and arranged. When the first heat storage material (a) and the second heat storage material (b) are used and the outside air temperature is lower than the desired temperature control target article such as in winter, the first heat storage material (a) is adjacent to the temperature control target article. A first heat storage material (a) having a solidification / melting temperature of 0 ° C. or higher and in a solidified state is arranged, and a second heat storage material in a molten state is placed on the outer periphery of the first heat storage material (a). An example is the one in which (b) is arranged.

On the other hand, using the first heat storage material (a) and the second heat storage material (b), the temperature of the first heat storage material (a) is adjusted so as to be in a molten state at a temperature higher than that of the article subject to temperature control. And place it adjacent to the temperature controlled article. On the other hand, the second heat storage material (b) is solidified and frozen under the condition of −15 ° C. or lower, and placed outside the first heat storage material (a). In this case, the second heat storage material (b) arranged outside the first heat storage material (a) serves as a heat buffering material against the outside air temperature for maintaining the temperature of the temperature-controlled article in a desired temperature range. Some that work are also exemplified.

When two or more types of heat storage materials with different solidification / melting states are used, the effects of temperature rise and fall due to the temperature difference with the outside air are placed adjacent to the article subject to temperature control via the heat insulating material that constitutes the container. It can be suppressed by using the second heat storage material (b) arranged outside the first heat storage material (a) and acting as a heat buffer material. Then, due to the temperature interaction between the first heat storage material (a) and the second heat storage material (b), the first heat storage material (a) in the melted state is cooled and the temperature drops, and the melted state (liquid). ) To the solidified state (solid) by releasing thermal energy, the temperature-controlled article can be protected from both higher and lower temperatures. As a result, the amount of the heat storage material used can be reduced, and the temperature-controlled article can be maintained within a predetermined temperature range for a longer period of time.
