On the other hand, the closed side wall 41 has a vertical dimension larger than that of the side wall 21, the side wall 22, and the opposing side wall 42. The vertical dimension of the closed side wall part 41 is a dimension obtained by adding the thickness of the top plate 11 to the vertical dimension of the side wall part 21, the side wall part 22, and the opposing side wall part 42.

In addition, a horizontal unevenness fitting portion (not shown) is formed at a portion facing the top plate portion 11 and the bottom plate portion 31, the

side wall portions

21 and 22, and the opposite side wall portion 42. This horizontal uneven | corrugated fitting part is comprised from the ditch | groove and the protruding item | line which extend in a horizontal direction. By this horizontal unevenness fitting portion, the upper end portion is fitted to the top plate portion 11 and the lower end portion is fitted to the bottom plate portion 31 in the

side wall portions

21 and 22 and the opposite side wall portion 42. Note that the ridges and horizontal grooves forming the horizontal uneven fitting portion only need to be formed in the facing portions of the top plate portion 11 and the bottom plate portion 31, the

side wall portions

21 and 22, and the opposing side wall portion 42. The formation location is not particularly limited.

Further, the side wall portion 21, the side wall portion 22, and the opposing side wall portion 42 are connected by a vertical uneven fitting portion (not shown) that connects the opposing surfaces of the side wall portions adjacent to each other. This vertical uneven | corrugated fitting part is comprised from the ditch | groove and the protruding item | line formed over the vertical direction up-and-down whole length of the rectangular-shaped board | plate material which comprises each side wall part. In addition, the ditch | groove and protrusion which comprise a vertical uneven | corrugated fitting part should just be formed in the opposing part with the

side wall parts

21 and 22 and the opposing side wall part 42, and a formation location is not specifically limited.

Further, as shown in FIGS. 2A and 2B and FIG. 3, vertical ridges 41 a are provided at both end portions of the closed side wall portion 41. The vertical ridge 41 a is formed over the entire vertical length of the closed side wall 41. A vertical groove 21 a that fits with the vertical ridge 41 a is formed on the opposite surface of the side wall 21 that faces the closed side wall 41. Similarly, a vertical groove that fits with the vertical ridge 41a is also formed on the opposite surface of the side wall 22 that faces the closed side wall 41.

Further, the top plate portion 11 is formed with a U-shaped notch 12. The notch 12 is provided at the end of the top plate 11 on the closed side wall 41 side. In the plan view, the closed side wall 41 is accommodated in the notch 12 of the top plate 11. Moreover, the vertical ditch | groove 11a in which the vertical protruding item | line 41a is inserted is provided in the side surface which opposes the vertical protruding item | line 41a of the obstruction | occlusion side wall part 41 in the notch part 12. As shown in FIG. The vertical groove 11 a is provided on both the side surface on the side wall 21 side and the side surface on the side wall 22 side in the notch 12. And in the side surface by the side wall part 21 side in the notch part 12, the vertical ditch | groove 11a is formed so that it may connect with the vertical ditch | groove 21a. Further, on the side surface of the notch portion 12 on the side wall portion 22 side, the vertical groove 11 a is formed so as to be connected to the vertical groove formed in the side wall portion 22.

Further, a horizontal ridge 41b is formed on the opposing surface of the closed side wall 41 that faces the bottom plate 31. The horizontal ridge 41b is formed over a portion of the closed side wall portion 41 between the one end in the X direction and the other end that ignores the portion of the vertical ridge 41a. Further, it can be said that the horizontal ridges 41 b are formed between the side wall part 21 and the side wall part 22. And in the opposing surface facing the obstruction | occlusion side wall part 41 in the baseplate part 31, the horizontal ditch | groove 31a fitted with the horizontal protruding item | line 41b is formed. The horizontal ridges 41b and the horizontal grooves 31a are different in shape from the ridges and grooves forming the horizontal unevenness fitting portion described above. The horizontal ridge 41b and the horizontal groove 31a are shaped so that the closed side wall 41 and the

side walls

21 and 22 are less likely to come off when fitted together. Therefore, when unpacking the constant temperature storage transport container 100, the

side walls

21 and 22 are unpacked before the closed side wall 41.

Thus, in the constant temperature storage and transport container 100, the top plate portion 11 and the bottom plate portion 31 are fitted to the

side wall portions

21 and 22 and the upper end portion and the lower end portion of the opposite side wall portion 42 by a horizontal uneven fitting portion (not shown). To do. And the adjacent side wall parts in the

side wall parts

21 and 22 and the opposing side wall part 42 are fitted by the vertical uneven | corrugated fitting part which is not shown in figure. Further, the closed side wall portion 41 is fitted to the top plate portion 11 and the side wall portion 21 by inserting the vertical ridges 41a into the vertical groove 11a and the vertical groove 21a. Further, the closed side wall portion 41 is fitted to the side wall portion 22 by inserting the vertical ridge 41 a into the vertical groove formed in the vertical groove 11 a and the side wall portion 22. Further, the closed side wall portion 41 is fitted to the bottom plate portion 31 by the horizontal ridge 41b being inserted into the horizontal groove 31a. Therefore, the inside of the constant temperature storage transport container 100 is a sealed space.

Here, the material of the constant temperature storage transport container 100 is not particularly limited as long as it has heat insulation properties, and foamed plastic and vacuum heat insulating material are preferably used. As the foamed plastic, specifically, polystyrene, polyethylene, polypropylene, or polyurethane foamed foam is used. Moreover, as a vacuum heat insulating material, the thing using silica powder, glass wool, glass fiber etc. for the core material is used, for example.

Furthermore, the constant temperature storage transport container 100 may be configured by a combination of foamed plastic and a vacuum heat insulating material. In that case, the outer surface or the inner surface of the container main body X and / or the closed side wall portion 41 made of foamed plastic is covered with a vacuum heat insulating material, or the vacuum heat insulating material is provided inside the wall constituting the container main body X and the closed side wall portion 41. By embedding, a transport container having high heat insulation performance can be obtained.

The constant temperature storage transport container 100 includes a storage material 51 (first heat storage material) disposed on the

side walls

21 and 22 and a storage material 52 (second heat storage material) disposed on the bottom plate portion 31. This is a configuration provided. More preferably, the storage material 51 is stored in the side wall portion 21 and the side wall portion 22, and the storage material 52 is stored in the bottom plate portion 31. Specifically, on the inner surfaces of the

side wall portions

21 and 22, a storage material 51 that is a heat storage material and a storage recess 23 that can store dry ice are provided. An accommodation recess 32 capable of accommodating a storage material 52 that is a heat storage material is provided on the upper surface of the bottom plate portion 31. In addition, the formation location of the accommodation recessed part 23 is not limited to the

side wall parts

21 and 22, What is necessary is just at least 1 among four side wall parts which comprise the constant temperature storage transport container 100. FIG. For example, the housing recess 23 may be formed on the closed side wall 41 or may be formed on the opposing side wall 42.

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

First, a rectangular plate material constituting the top plate portion 11, a rectangular plate material constituting the

side wall portions

21 and 22, and a rectangular shape constituting the bottom plate portion 31 by the horizontal unevenness fitting portion and the vertical unevenness fitting portion. The container body X is assembled by fitting the plate material and the rectangular plate material constituting the opposed side wall portion 42. In addition, the order of fitting of each rectangular plate material which comprises the container main body X can be suitably set according to the formation location etc. of the said horizontal uneven | corrugated fitting part and the said vertical uneven | corrugated fitting part.

Next, the container body X assembled in this manner is assembled by fitting a rectangular plate material constituting the closed side wall portion 41, whereby the constant temperature storage and transport container 100 is completed. At this time, the lower ends of the vertical ridges 41a formed on both side ends of the closed side wall 41 are formed on both the side wall 21 side and the side wall 22 side in the notch 12 of the top plate part 11, respectively. A rectangular plate material constituting the closed side wall 41 is installed so as to be inserted into the vertical groove 11a. In this state, the vertical plate 41a passes through the vertical groove 11a of the top plate portion 11 by moving the rectangular plate material constituting the closed side wall portion 41 vertically downward, so that the vertical recess of the side wall portion 21 is The vertical groove formed in the groove 21a and the side wall portion 22 slides. Then, the closed side wall 41 is assembled to the container body X by fitting the horizontal ridge 41 b of the closed side wall 41 into the horizontal groove 31 a of the bottom plate portion 31.

As described above, in the constant temperature storage and transport container 100, the top plate portion 11 and the closed side wall portion 41 adjacent to each other are slid 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 11 and the closed side wall portion 41. This sliding fitting part consists of a protruding item | line and a ditch | groove, and it is comprised so that a protruding item | line can slide a ditch | groove.

More specifically, the ridges in the sliding fitting portion are vertical ridges 41 a formed at both end portions of the closed side wall portion 41. Further, the groove in the sliding fitting portion includes a vertical groove 11 a formed on the side wall 21 side in the notch 12, a vertical groove 21 a in the side wall 21, and a side wall 22 in the notch 12. It is comprised by the vertical ditch | groove 11a formed in the side, and the vertical ditch | groove formed in the side wall part 22. FIG. The vertical groove 11a formed on the side wall 21 side in the notch 12 and the vertical groove 21a of the side wall 21 are connected to each other. Moreover, the vertical ditch | groove 11a formed in the side wall part 22 side in the notch part 12 and the vertical ditch | groove formed in the side wall part 22 mutually connect. Therefore, the closed side wall portion 41 slides between the outer side and the inner side of the top plate portion 11 by the sliding fitting portion configured as described above. By providing the sliding fitting portion in this manner, the opening / closing operation of the constant temperature storage transport container 100 can be performed only by the operation of sliding the closed side wall portion 41, and convenience is improved.

Further, according to the configuration of the constant temperature storage transport container 100, the opening and closing operation of the constant temperature storage transport container 100 can be simplified compared to the configuration in which the container body is closed by the top plate portion. For this reason, it is possible to easily store the temperature management target article requiring low temperature storage in the constant temperature storage transport container 100 by shortening the time for contacting the outside air. In the configuration in which the container body is closed by the top plate portion, (a) after placing the bottom plate portion, the temperature management target article is arranged, (b) three side wall portions are arranged to accommodate the temperature management target article, or (C) The temperature management object is housed in the constant temperature storage and transport container by any method of housing the temperature management object from the top surface after assembling the bottom plate part and the side wall part. Regardless of the method of (a) to (c), the temperature management target article is kept in contact with the outside air even if it is accommodated.

Further, in the case where the temperature management target article is stored from the top as in (c) above, when the temperature management target article is stored by a human hand, the human body is placed in the constant temperature storage transport container in which the dry ice is arranged. It is necessary to put in. For this reason, although the safety aspect is ensured also in the structure which obstruct | occludes a container main body by a top-plate part, there is not a small possibility that the danger degree in a safety aspect (oxygen deficiency, carbon dioxide poisoning) will increase.

In addition, as the time in which the outside air is touched becomes longer, the temperature of the temperature management target item that needs to be maintained at a low temperature rises due to the outside air, and a part of the temperature may be melted.

On the other hand, the constant-temperature storage transport container 100 having the above-described sliding fitting portion can be accommodated without increasing the temperature of the temperature management target article. In addition, by designing the container to accommodate the temperature control target article by the opening / closing operation from the closed side wall portion 41, the risk of oxygen deficiency and carbon dioxide poisoning due to dry ice is greatly reduced.

In the configuration described above, the ridges (vertical ridges 41a) constituting the sliding fitting portion are formed on the closed side wall portion 41, while the concave grooves (vertical vertices constituting the sliding fitting portion are provided). 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 formation positions of the ridges and the grooves may be any positions that can be fitted to each other to form the 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 grooves constituting the sliding fitting portion are formed on the closed side wall portion 41. It may be.

By the way, in the configuration in which the storage material and the dry ice as the heat storage material are stored in the wall portion constituting the constant temperature storage and transport container 100 as described above, the space inside the container is secured while storing the temperature management target article. It was difficult to keep the temperature at a low temperature for a long time. For example, the constant temperature storage and transport container described in Patent Document 1 has a configuration in which the storage material stored in the side wall and the storage material stored in the bottom plate are separated by the heat insulating material of the container body. Therefore, for example, when the dry ice is disposed so as to contact the storage material, the dry ice contacts both the storage material and the heat insulating material of the container body. For this reason, when the volume of dry ice decreases due to sublimation, it accumulates at the bottom and finally comes into contact with the heat insulating material of the container body. As a result, the dry ice finally accumulated at the bottom is deprived of latent heat by the heat insulating material, sublimates relatively quickly, and the volume becomes small. For this reason, the latent heat of the dry ice finally accumulated at the bottom cannot be effectively used for cooling the storage material as the heat storage material. In the constant temperature storage and transport container described in Patent Document 1, there is room for improvement in that the latent heat of dry ice is effectively used when used together with dry ice.

The constant temperature storage transport container 100 according to the present embodiment has a configuration that can effectively use the latent heat of dry ice finally accumulated at the bottom for cooling the storage material that is a heat storage material. FIG. 4A is a cross-sectional view showing the positional relationship between the

storage materials

51 and 52 and the dry ice 61 accommodated in the constant temperature storage and transport container 100 according to the present embodiment. FIG. 4B is a cross-sectional view showing a state where the dry ice 61 is accumulated at the bottom due to the volume reduction due to sublimation.

As shown in FIG. 4A, a plurality of storage materials 51 are stacked in the storage recess 23 in the vertical direction. The arranged storage materials 51 are in contact with each other. A plurality of storage materials 52 are arranged in the horizontal direction in the storage recesses 32. The arranged storage materials 52 are in contact with each other.

In the constant temperature storage transport container 100, the storage material 51 accommodated in the accommodation recess 23 of the

side wall portions

21 and 22 and the storage material 52 (second heat storage material) accommodated in the bottom plate portion 31 are in contact with each other. Yes. Further, in the housing recess 23, a dry ice storage chamber D is formed by the storage material 51, the storage material 52, and the outer side wall surface 23 a of the storage recess 23 facing the storage material 51. The storage material 51 and the storage material 52 constitute a part of the wall portion of the dry ice storage room D. The dry ice 61 stored in the dry ice storage chamber D is disposed so as to be in contact with both the

storage materials

51 and 52.

Therefore, as shown in FIG. 4B, the dry ice 61 is in contact with both the

storage materials

51 and 52 even when the dry ice 61 is accumulated at the bottom due to the volume reduction due to sublimation. As a result, since the

storage materials

51 and 52 are cooled by the dry ice 61 accumulated at the bottom, the latent heat of the dry ice 61 finally accumulated at the bottom is effectively used for cooling the

storage materials

51 and 52. it can. Further, since the latent heat of the dry ice 61 can be effectively used, the space for installing the dry ice 61 can be reduced, and a sufficient space can be secured for storing the temperature management target article. Therefore, in the constant temperature storage transport container 100, the inside of the container can be kept at a low temperature for a long time while securing a space for storing the temperature management object.

It should be noted that the constant temperature storage transport container 100 may have a configuration that can effectively use the latent heat of the dry ice 61 for cooling at least one of the storage material 51 and the storage material 52. Therefore, the dry ice 61 may be in contact with at least one of the storage material 51 and the storage material 52. For example, the dry ice 61 may be disposed so as to contact only the storage material 52 and be separated from the storage material 51. Even in such a configuration, the latent heat of the dry ice 61 can be effectively used for cooling the storage material 51 and the storage material 52.

Further, it is preferable that the difference between the melting temperature of the

heat storage materials

51 and 52 and the sublimation temperature (−78 ° C.) of the dry ice 61 is as small as possible. Thereby, the volume reduction rate by the sublimation of the dry ice 61 can be reduced, and the latent heat of the dry ice 61 can be effectively used for cooling the

storage materials

51 and 52.

Also, when the dry ice 61 is exposed to air or the like, it sublimes faster and the volume decreases. Therefore, it is preferable that the dry ice 61 is disposed outside the storage material 51. With such a configuration, the dry ice 61 is disposed in contact with both the storage material 51 and the outer side wall surface 23 a of the storage recess 23. Therefore, the air exposure area in the dry ice 61 can be reduced, and volume reduction due to sublimation can be suppressed.

Further, when the sublimation temperature of the dry ice 61 is compared with the melting temperature of the storage material 51 (heat storage material), the storage material 51 generally has a melting point higher than the sublimation temperature of the dry ice 61. Therefore, if the dry ice 61 is arranged outside the storage material 51, the sublimation heat of the dry ice 61 can be used effectively and the inside of the constant temperature storage and transport container 100 can be maintained at a low temperature for a long time.

The arrangement of the storage material 51 and the dry ice 61 is not limited to the arrangement shown in FIGS. 4 (a) and 4 (b). When the storage material 51 has a melting point lower than the sublimation temperature of the dry ice 61, the dry ice 61 may be disposed on the inner side of the storage material 51.

The constant temperature storage transport container 100 includes a storage material 53 (third heat storage material) and dry ice 61 disposed on the opposite side of the bottom plate portion 31 in the temperature management target article stored in the constant temperature storage transport container 100. It may be. FIG. 5 shows a modified example of the constant temperature storage transport container 100 including the storage material 53 and the dry ice 61. FIG. 5A is a cross-sectional view showing a configuration of the storage frame Y1 for storing the storage material 53 and the dry ice 61, and FIG. 5B is a constant temperature storage transport container in which the storage frame Y1 is arranged. 1 is a top view showing the configuration of 100. FIG. In addition, the top plate part 11 is abbreviate | omitted in (b) of FIG.

As shown in (a) and (b) of FIG. 5, in the constant temperature storage and transport container 100, the storage material 53 and the dry ice 61 are separately stored in the separate storage frame Y 1 and It is arrange | positioned on the opposite side to the baseplate part 31, ie, the upper side of the temperature management object article. The storage material 53 and the dry ice 61 are not stored in the top plate portion 11.

The housing frame Y1 is configured to be engaged with the side wall portion to hold the position. As a result, a cargo room space for accommodating the temperature management target article is secured in the constant temperature storage transport container 100.

(Regarding storage materials 51 to 53 which are heat storage materials)
The heat storage material (also referred to as cold storage material) in the storage materials 51 to 53 is obtained by enclosing a heat storage component (also referred to as cold storage component) in a plastic container, a film bag, or the like.

As the material of the container or bag filled with the heat storage component, a material that does not cause low-temperature brittleness at the sublimation temperature of dry ice or that is relatively resistant to low-temperature brittleness is preferable. Examples of the material of the container or bag filled with the heat storage component include polyethylene, polycarbonate, polystyrene, polyphenyl oxide, or fluororesin, and one of these materials may be used alone, In order to improve the properties and barrier properties, it is also possible to use a multilayer structure obtained by combining two or more of these materials. The shape of the container or bag is not particularly limited, but a shape that can ensure a large surface area is preferable from the viewpoint of increasing the heat exchange rate.

The storage materials 51 to 53 are preferably latent heat storage materials. The latent heat type heat storage material uses thermal energy that accompanies the phase transition of the heat storage component and absorbs when the phase state of the heat storage component changes from a solid state (solid) to a molten state (liquid). Or thermal energy released when the phase transition from a molten state (liquid) to a solidified state (solid) is utilized.

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, SII EXSTAR 6000 DSC manufactured by Seiko Instruments Inc.) is used and measured at a rate of temperature increase of 2 ° C./min. The maximum peak temperature is defined as the solidification / melting temperature.

The phase state generally represents three phase states of a solid, a liquid, and a gas. In this 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. For example, a phase state in which 80% by weight of the heat storage component is a solid state and 20% by weight is a liquid state is a solid (solidified state).

The composition constituting the latent heat type heat storage component used in the present embodiment only needs to be contained in the heat storage material used in a container for the purpose of maintaining a low temperature in combination with dry ice. As the composition constituting the latent heat type heat storage component, for example, those containing water as a main component, for example, potassium bicarbonate aqueous solution, potassium chloride aqueous solution, ammonium chloride aqueous solution, sodium chloride aqueous solution, calcium chloride aqueous solution, calcium bromide aqueous solution, The thing containing water and a super absorbent polymer is mentioned.
