Description

Technical Field

[0001] This invention relates to a connector for a constant-temperature conveying container and a heat storage material encapsulation component. Background Technology

[0002] As a method for transporting or storing articles such as pharmaceuticals, medical devices, cells, specimens, organs, chemicals, or food in a cold or warm state, the following method can be cited. That is, a method in which pre-frozen or solidified cold-storage or heat-storage material is placed inside an insulated container to serve as a cold-storage or heat-storage container, and the latent heat of fusion or solidification of the cold-storage or heat-storage material is used to transport or store the articles contained within the insulated transport container while maintaining their temperature. In order to maintain the articles that will be the object of the aforementioned heat preservation (hereinafter sometimes referred to as "temperature-storage articles") within a specified temperature range (hereinafter sometimes referred to as "managed temperature") for a long period of time, a constant-temperature transport container is preferably used. This constant-temperature transport container includes a cold-storage or heat-storage material having a melting temperature within the specified temperature range, and an insulated container. Typically, a constant-temperature transport package is formed to encapsulate the temperature-storage articles within the constant-temperature transport container to transport the temperature-storage articles.

[0003] In recent years, a technology has been proposed in the field of constant-temperature conveyor packaging: manufacturing a tray carrying temperature-controlled items, and then mounting the tray together with the constant-temperature conveyor packaging. This technology requires a pallet-in-pallet shipper. However, in order to form a structure that can carry the tray carrying the temperature-controlled items, the constant-temperature conveyor packaging must be large. Moreover, with this increase in size, the amount of heat-storing material mounted on the constant-temperature conveyor packaging also increases. In addition, when the side wall panels are designed to insert the heat-storing material from above, if the side wall panels are made larger, the height of the side wall panels increases, making it difficult for the user to seal the heat-storing material from above. Furthermore, when moving the side wall panels and top panels containing the heat-storing material, the weight of the panels due to the heat-storing material becomes very heavy, making operation difficult.

[0004] As a technology to solve the problem of inserting heat storage material from above the aforementioned side wall panel, for example, patent documents 1 and 2 disclose a constant temperature conveying container that allows heat storage material to be inserted from the side of the side wall panel.

[0005] Furthermore, the constant-temperature conveying containers disclosed in Patent Documents 3 and 4 have a structure in which the heat storage material is inserted vertically relative to the side wall panel (hereinafter, sometimes referred to as a longitudinal insertion structure). Additionally, the constant-temperature conveying container disclosed in Patent Document 5 has a structure in which the heat storage material is inserted horizontally relative to the side wall panel (hereinafter, sometimes referred to as a transverse insertion structure).

[0006] In addition, in recent years, the workability of thermal storage material packaging has been emphasized in the field of constant temperature delivery packaging. As a method to improve the workability of thermal storage material packaging, the packaging time can be significantly shortened by designing a connector that links thermal or cold storage material packaging components.

[0007] Existing connectors for heat storage or cold storage material encapsulation components are disclosed, for example, in Patent Documents 6 and 7.

[0008] Patent Document 6 discloses a connector for encapsulating heat storage material, comprising a strip having multiple storage bags, each containing heat storage material. The connector of Patent Document 6 is used by winding it around an article intended for temperature maintenance.

[0009] Furthermore, Patent Document 7 discloses a connector having a cold storage plate as a heat storage material encapsulation component. This cold storage plate contains a freezeable refrigerant. Patent Document 7 also discloses a cold storage body consisting of multiple such cold storage plates connected by hinges. The multiple cold storage plates are connected via a connecting portion in a manner capable of rotating at least 180 degrees. The cold storage body of Patent Document 7 is configured to allow for selection of a state where the cold storage plates are overlapped and a state where the cold storage plates are unfolded when maintaining cold through the cold storage body and when freezing the refrigerant in the cold storage body.

[0017] However, in the technologies described in Patent Documents 1-7, there is room for improvement in preventing the inflow of external air into the sidewall panel. Furthermore, there is room for improvement in the efficiency of encapsulating the heat storage material relative to the sidewall panel. Summary of the Invention

[0018] One aspect of the present invention is to provide a constant-temperature delivery container that prevents external air from flowing into the interior of the sidewall panel and that can efficiently encapsulate heat storage material relative to the sidewall panel.

[0019] To address the aforementioned issues, one aspect of the present invention relates to a constant-temperature transport container capable of transporting temperature-maintaining articles at a constant temperature. The container is characterized by having four sidewall panels, a top panel, and a bottom panel. Each sidewall panel includes: a first receiving portion for receiving heat-storing material; and a first insertion port disposed on one side of the sidewall panel for inserting the heat-storing material into the first receiving portion. The sides of the four sidewall panels with the first insertion ports are adjacent to each other, forming first insertion corners for the heat-storing material, with the first insertion ports exposed to the outside. Two first insertion corners are formed in a mutually opposing manner. The sidewall panels are connected to each other on the side opposite to the first insertion corners. A first fitting corner is provided at each first insertion corner, closing the first insertion port and fitting into the side with the first insertion port.

[0020] According to one aspect of the present invention, it is possible to prevent the inflow of external air into the interior of the sidewall panel and to efficiently encapsulate the heat storage material relative to the sidewall panel. Attached Figure Description

Detailed Implementation

[0047] [Summary of Embodiments 1 to 6 of the Invention]

[0048] As described above, in existing constant-temperature conveying containers (e.g., Patent Documents 1 and 2) that allow for the insertion of heat storage material from the side of the sidewall panel, there is room for improvement, for example, in the following aspects.

[0049] In the constant-temperature conveying container of Patent Document 1, after the heat storage material is inserted into an insertion port formed on the side of the side wall panel, the insertion port is sealed by an upright rod. This easily creates a gap between the insertion port of the heat storage material and the upright rod, making it impossible to prevent external air from flowing into the interior of the side wall panel. Therefore, in the constant-temperature conveying container of Patent Document 1, high dimensional accuracy is required for both the sealing component and the insertion port to prevent external air from flowing into the interior of the side wall panel. In the constant-temperature conveying container of Patent Document 1, there is room for improvement in preventing external air from flowing into the interior of the side wall panel.

[0050] Furthermore, in the technology described in Patent Document 2, after assembling the four sidewall panels, it is impossible to encapsulate the heat storage material from the sides of all four sidewall panels. Therefore, in the constant-temperature delivery container of Patent Document 2, there is room for improvement in the efficiency of encapsulating the heat storage material relative to the sidewall panels.

[0051] Therefore, in the constant temperature conveying container according to this embodiment, the four side wall panels include: a receiving portion for receiving heat storage material inside; and an insertion port provided on one side of the side wall panel for inserting the heat storage material into the receiving portion. Moreover, the four side wall panels have the following structures (1) to (4): (1) The side panels provided with the insertion ports form insertion corners of the heat storage material adjacent to each other with the insertion ports exposed to the outside. (2) Two insertion corners are formed in a mutually opposing manner. (3) The side wall panels are connected to each other on the side opposite to the insertion corners. (4) A fitting corner is provided at the insertion corner, the fitting corner closes the insertion port and fits into the side panel provided with the insertion port.

[0052] According to the structures described in (1) to (3) above, after assembling the four sidewall panels, the mounting portions of the heat storage material converge at the two insertion corners. Therefore, the user can efficiently encapsulate the heat storage material relative to all four sidewall panels after assembling them.

[0053] Furthermore, according to the structure described in (4) above, the insertion port is sealed by fitting the insertion corner portion with the fitting corner portion. Moreover, this complex-shaped fitting structure can prevent external air from flowing into the interior of the side wall panel.

[0054] [Implementation Method 1]

[0055] Hereinafter, one embodiment of the present invention will be described in detail. Figure 1 This is an exploded perspective view showing the outline structure of the constant temperature conveying container 10 according to this embodiment.

[0056] like Figure 1 As shown, the constant-temperature transport container 10 is a rectangular box-shaped assembled container capable of transporting temperature-controlled items at a constant temperature. It consists of a container body X with an open upper surface and a top panel 6 that closes the open upper surface of the container body X. The container body X is composed of four side wall panels 1, 2, 3, and 4 and a bottom panel 5. The side wall panels 1, 2, 3, and 4, the bottom panel 5, and the top panel 6 are made of heat-insulating materials and are rectangular in shape when viewed from above.

[0057] The bottom panel 5 is composed of rectangular plates that can be separated from the side wall panels 1, 2, 3, and 4. Similarly, the side wall panels 1, 2, 3, and 4 are each composed of rectangular plates. These rectangular plates are separable from each other. Here, for each of the rectangular plates constituting the side wall panels 1, 2, 3, and 4, the direction defining the thickness is called the thickness direction, and the direction defining the height relative to the vertical direction when the bottom panel 5 is erected is called the height direction. Furthermore, the direction perpendicular to both the height direction and the thickness direction is called the lateral or horizontal direction. Additionally, relative to the side wall panels 1-4, the bottom panel 5, and the top panel 6, the storage chamber side of the constant-temperature conveying container 10 is designated as the inner side, and the side opposite to this inner side is designated as the outer side.

[0058] Side wall panels 1, 2, 3, and 4 and bottom panel 5 are connected by a known connecting mechanism. For example, side wall panels 1, 2, 3, and 4 are connected to bottom panel 5 by a concave-convex structure. In this case, a concave-convex fitting structure is formed between the lower end of each of the side wall panels 1, 2, 3, and 4 and the opposing portion of the bottom panel 5 relative to that lower end. In addition, the upper end of each of the side wall panels 1, 2, 3, and 4 is fitted with the top panel 6.

[0059] Next, the structure of side wall panels 1 to 4 will be described. Furthermore, the following description will focus on the structure of side wall panels 1 and 2. Since the structure of side wall panels 3 and 4 is the same as that of side wall panels 1 and 2, descriptions will be omitted.

[0060] The sidewall panel 1 has a storage portion 1a (first receiving portion) for storing storage materials P1 and P2 as heat storage materials, and an insertion port 1b (first insertion port) for inserting the storage materials P1 and P2 into the storage portion 1a. The insertion port 1b is formed on one side 1c of the sidewall panel 1. The storage portion 1a forms a space for storing the storage materials P1 and P2 inside the sidewall panel 1 and extends horizontally from the insertion port 1b. The storage portion 1a does not reach the other side 1d of the sidewall panel 1. That is, the storage portion 1a is not a hole that extends from one side 1c to the other side 1d. Therefore, the insertion port 1b is not formed on the other side 1d of the sidewall panel 1. In addition, in Figure 1 In the structure shown, there are three storage sections 1a arranged in the height direction. However, the number of storage sections 1a can be appropriately set according to the size of the side wall panel 1, the size of the storage materials P1 and P2, etc.

[0061] Additionally, the side wall panel 2 includes a storage portion 2a (first receiving portion) for storing storage materials P1 and P2, which are heat storage materials; and an insertion port 2b (first insertion port) for inserting storage materials P1 and P2 into the storage portion 2a. The storage portion 2a and the insertion port 2b have the same structure as the storage portion 1a and the insertion port 1b of the side wall panel 1, so their description is omitted.

[0062] Here, in Figure 1 In the constant temperature conveying container 10 shown, insertion openings are formed on the sides of each of the side wall panels 1 to 4, and a receiving portion extending horizontally from the insertion opening is provided. Therefore, when assembling the constant temperature conveying container 10, receiving materials P1 and P2 can be inserted from the side relative to the side wall panels 1 to 4 respectively.

[0063] Existing constant-temperature delivery containers have a structure where the storage material is inserted from above the side panel. In this structure, if the size of the constant-temperature delivery container increases, the height of the side panel also increases, making it difficult for the user to store the storage material inside. This is especially problematic for shorter women assembling the container, as their line of sight and hands cannot easily reach the insertion point on the side panel, making it difficult to store the storage material. Furthermore, after the storage material is inserted, moving the side panel results in significant weight, further complicating the operation.

[0064] Compared to existing constant-temperature conveying containers, in the constant-temperature conveying container 10, during assembly, the storage materials P1 and P2 can be inserted from the sides of each of the side wall panels 1 to 4. Therefore, even if the size of the constant-temperature conveying container increases and the height of the side wall panels increases, the insertion ports for the storage materials are easily accessible to the user. As a result, storing the storage materials in the side wall panels becomes easier in the constant-temperature conveying container 10. Furthermore, there is no need to move the heavy side wall panels after the storage materials are inserted. Consequently, the workload of the assembly operation can be reduced.

[0065] Here, the constant temperature conveying container 10 according to this embodiment can prevent external air from flowing into the interior from the side wall panels 1 to 4 respectively, and can efficiently encapsulate heat storage material relative to the side wall panels 1 to 4 respectively.

[0066] In the constant temperature conveying container 10, two insertion corners Y and Z (first insertion corners) are formed on the four side wall panels 1 to 4. The two insertion corners Y and Z are opposite to each other. In this way, the insertion corners Y and Z are arranged opposite each other, thereby stabilizing the structure of the constant temperature conveying container 10 even when the fitting corner 7 is not fitted into the insertion corners Y and Z. For the side wall panels 1 and 2, the insertion corner Y is composed of a side surface 1c with an insertion port 1b and a side surface 2c with an insertion port 2b. In addition, the insertion corner Z has the same structure as the insertion corner Y. That is, for the side wall panels 3 and 4, the insertion corner Z is composed of side surfaces 3c and 4c with insertion ports for receiving materials P1 and P2. Hereinafter, the insertion corner Y will be described. Since the insertion corner Z is the same as the insertion corner Y, the description is omitted.

[0067] In the side wall panels 1 and 2, the side surfaces 1c and 2c form an insertion corner Y with the insertion openings 1b and 2b exposed to the outside and adjacent to each other.

[0068] In the constant-temperature conveying container 10, side wall panels 1 and 4 are connected to each other on side 1d opposite to the insertion corner Y and side 4d opposite to the insertion corner Z. Similarly, side wall panels 2 and 3 are connected to each other on side 2d opposite to the insertion corner Y and side 3d opposite to the insertion corner Z. The structure described here, where side 1d and side 4d are connected, includes a structure where one side of side 1d and side 4d contacts and is connected to a side wall panel having the other side, and a structure where side 1d and side 4d contact and are connected to each other. Figure 1 In the structure shown, the structure where side 1d and side 4d are connected is a structure in which side 4d of side wall panel 4 contacts and is connected to side wall panel 1.

[0069] In the constant temperature conveying container 10, a fitting corner portion 7 (first fitting corner portion) is provided at the insertion corner Y. The fitting corner portion 7 is configured to close the insertion ports 1b and 2b and fit into the side surfaces 1c and 2c where the insertion ports 1b and 2b are respectively provided. Specifically, a fitting recess 1e is provided on the side surface 1c where the insertion port 1b is provided in the side wall panel 1. In addition, a fitting recess 2e is provided on the side surface 2c where the insertion port 2b is provided in the side wall panel 2. The fitting recesses 1e and 2e are grooves that extend in the vertical direction.

[0070] The fitting corner portion 7 has a cuboid shape that accommodates the space formed by the side surface 1c and the side surface 2c within the insertion corner portion Y. The fitting corner portion 7 fits into the insertion corner portion Y in a manner coplanar with the side wall panels 1 and 2. Fitting protrusions 7e and 7e are provided on the surfaces of the fitting corner portion 7 that face the side surfaces 1c and 2c, respectively. The two fitting protrusions 7e and 7e are protruding strips that extend in the vertical direction. One of the two fitting protrusions 7e and 7e fits into the fitting recess 1e, and the other fitting protrusion 7e fits into the fitting recess 2e. In this way, in the constant temperature conveying container 10, the side surfaces 1c and 2c of the side wall panels 1 and 2, which are provided with insertion ports 1b and 2b, are respectively provided with fitting recesses 1e and 2e for fitting into the insertion corner portion Y. Moreover, the fitting corner portion 7 is provided with fitting protrusions 7e and 7e that fit into the fitting recesses 1e and 2e.

[0071] At the insertion corner Y, the sides 1c and 2c of the side wall panels 1 and 2 engage with the fitting corner 7, thereby sealing the insertion ports 1b and 2b. As a result, it is possible to prevent external air from flowing into the receiving portion 1a of the side wall panel 1. Similarly, it is possible to prevent external air from flowing into the receiving portion 2a of the side wall panel 2.

[0072] In the constant temperature transport container 10, the fitting corner 7 is fixedly relative to the insertion corner Y by a fitting structure. In this way, the insertion ports 1b and 2b are closed by the fitting corner 7 which is fixedly relative to the insertion corner Y, thus more reliably preventing the inflow of external air into the side wall panels 1 and 2.

[0073] Next, the assembly method of the constant temperature conveying container 10 will be described.

[0074] First, a side wall panel 1 is erected relative to the bottom panel 5. At this time, it is connected to the bottom panel 5 by fitting together, for example, a concave-convex fitting structure formed between the side wall panel 1 and the bottom panel 5. Next, a side wall panel 2 is arranged relative to the side wall panel 1 such that an insertion corner Y is formed by side surface 1c and side surface 2c, and in this state, the side wall panel 2 is erected relative to the bottom panel 5. Furthermore, the method of erecting side wall panels 2 to 4 relative to the bottom panel 5 is the same as the method of erecting side wall panels 1 relative to the bottom panel 5, therefore, its description is omitted.

[0075] Next, side wall panel 4 is erected relative to bottom panel 5 such that side surface 4d of side wall panel 4 is connected to side surface 1d of side wall panel 1. Furthermore, side wall panel 3 is erected relative to bottom panel 5 such that side surface 3d of side wall panel 3 is connected to side surface 2d of side wall panel 2. By erecting side wall panels 3 and 4 relative to bottom panel 5 in this way, the side surface 3c of side wall panel 3 and the side surface 4d of side wall panel 4 form the insertion corner Z.

[0076] This creates a structure in which sidewall panels 1, 2, 3, and 4 are erected relative to the bottom panel 5. Relative to this structure, storage materials P1 and P2 are inserted through insertion ports 1b, 2b, 3b, and 4b to encapsulate them within the sidewall panels 1 to 4. Here, the insertion corners Y and Z are opposite each other. Furthermore, the insertion ports 1b, 2b, 3b, and 4b for storage materials P1 and P2 converge at the insertion corners Y and Z. Therefore, when encapsulating storage materials P1 and P2 within the sidewall panels 1 to 4, the user can access all insertion ports 1b, 2b, 3b, and 4b simply by moving to either of these two locations. Thus, efficient encapsulation of storage materials P1 and P2 relative to each of the sidewall panels 1, 2, 3, and 4 is achieved. Furthermore, since the insertion ports 1b, 2b, 3b and 4b of the storage materials P1 and P2 are located in two places, the assembly space of the constant temperature conveying container 10 can be reduced.

[0077] Furthermore, the constant-temperature delivery container 10 has four side wall panels 1-4 erected relative to the bottom panel 5, forming insertion corners Y and Z. Therefore, the user does not need to erect the very heavy side wall panels 1-4, which contain the storage materials P1 and P2, relative to the bottom panel 5. The user only needs to erect the lighter side wall panels 1-4, which do not contain the storage materials P1 and P2, on the bottom panel 5. Therefore, according to the structure of the constant-temperature delivery container 10, the burden on the user from assembling the side wall panels 1-4 can be reduced.

[0078] After encapsulating the storage materials P1 and P2 onto the side wall panels 1 to 4, the fitting corner 7 is fitted into the insertion corners Y and Z, thereby forming the container body X. Furthermore, by connecting the top panel 6 to the upper end of the assembled container body X, the constant temperature delivery container 10 is completed.

[0079] As described above, the constant temperature conveying container 10 according to this embodiment can prevent external air from flowing into the interior of the side wall panels 1 to 4, and can efficiently encapsulate and store materials P1 and P2 relative to the side wall panels 1 to 4.

[0080] Here, the material used for the constant-temperature conveying container 10 is not particularly limited as long as it has heat insulation properties; foamed plastics and vacuum insulation components are preferred. Specifically, foamed plastics are materials obtained by foaming polystyrene, polyethylene, polypropylene, polyurethane, or poly(3-hydroxyalkanoate) resins. Furthermore, materials containing radiative heat transfer inhibitors are preferred for excellent heat insulation. For example, carbon-containing bead-based foamed bodies containing carbon that can act as radiative heat transfer inhibitors can be cited. Examples of carbon include graphite, graphene, activated carbon, coke, and carbon black. From the perspective of balancing cost and improved heat insulation, graphite and carbon black are preferred, with graphite being even more preferred. Additionally, structures using silica powder, glass wool, or glass fiber in the core material can be cited as examples of vacuum insulation components.

[0081] Furthermore, the constant-temperature conveying container 10 can also be composed of a combination of two or more foamed plastics. Specifically, examples of such a combination include a foam obtained by foaming polyethylene and a foam obtained by foaming polystyrene.

[0082] Furthermore, the constant-temperature conveying container 10 can also be constructed from a combination of foamed plastic and vacuum insulation. In this case, a conveying container with high thermal insulation performance is obtained by covering the outer or inner surface of the container body X and / or the top panel 6 made of foamed plastic with vacuum insulation, or by embedding the vacuum insulation inside the wall constituting the container body X and the top panel 6.

[0083] Furthermore, in the constant temperature conveying container 10, the fitting structure of the sides 1c and 2c with the fitting corner 7 is not particularly limited. From the viewpoint of improving the efficiency of the fitting corner 7 relative to the insertion corner Y, it is preferable that the fitting corner 7 is inserted and fitted from the side of the constant temperature conveying container 10 (hereinafter referred to as the horizontal insertion structure).

[0084] For example in Figure 1In the structure shown, the horizontal insertion configuration is preferably such that the fitting corner 7 can be fitted with the insertion corner Y in the horizontal direction. The horizontal insertion configuration can be implemented, for example, by the following structure: when viewed from the horizontal direction of the other side wall panel, the fitting recess of at least one of the side wall panels 1 and 2 is exposed to the fitting surface of the fitting corner 7.

[0085] For example, regarding the horizontal insertion construction described above, in Figure 1 In the structure shown, when viewed from the horizontal direction of the other sidewall panel 2, the mating surface of the recess 1e of one sidewall panel 1 and the mating surface of the protrusion 7e are exposed. That is, the mating surface of the recess 1e and the protrusion 7e is not obscured by the outer surface of the sidewall panel 1, and can be visually confirmed from the horizontal direction of the sidewall panel 2. In other words, the recess 1e is located at the outermost end of the side surface 1c of the sidewall panel 1, and no outer sidewall is formed for the recess 1e.

[0086] According to this horizontal insertion structure, in order to engage the fitting recess 1e with one of the fitting protrusions 7e, the fitting corner portion 7 is moved from the side of the constant temperature conveying container 10 in a manner close to the side surface 1c. Therefore, if the fitting recess 1e engages with one of the fitting protrusions 7e, the fitting recess 2e and the other fitting protrusion 7e can also engage with each other. Thus, it is not necessary for the fitting protrusion 7e of the fitting corner portion 7 to engage from above relative to the fitting recesses 1e and 2e, thereby improving the efficiency of the fitting operation of the fitting corner portion 7.

[0087] Furthermore, the preferred fitting corner portion 7 is a structure that fits not only with the sides 1c and 2c, but also with at least one of the bottom panel 5 and the top panel 6. In other words, it is preferred that at least one of the bottom panel 5 and the top panel 6 is connected to the fitting corner portion 7 via a fitting structure. Thus, the fitting corner portion 7 is also fixed by fitting relative to at least one of the bottom panel 5 and the top panel 6, and therefore the fitting corner portion 7 is firmly held relative to the insertion corner portion Y.

[0088] Furthermore, the fitting structure of sides 1c and 2c with the fitting corner 7 is not particularly limited. From the viewpoint of maximizing the efficiency of inserting the storage materials P1 and P2 into the insertion ports 1b and 2b of the insertion corner Y, such as Figure 1 As shown, it is preferable to provide fitting recesses 1e and 2e on sides 1c and 2c instead of fitting protrusions. When fitting protrusions are provided on sides 1c and 2c, it may be difficult to insert the storage materials P1 and P2 into the insertion ports 1b or 2b due to these fitting protrusions.

[0089] (Regarding storage materials P1 and P2)

[0090] The storage materials P1 and P2 are heat storage materials, respectively. The heat storage materials mentioned here include not only the heat storage material itself but also the cold storage material. That is, the storage materials P1 and P2 are at least one of heat storage materials and cold storage materials. Heat storage materials or cold storage materials refer to materials that encapsulate heat storage components or cold storage components in plastic containers, film bags, etc.

[0091] The material used for containers or bags filled with heat-storing or cold-storing components is not particularly limited, and examples include polyethylene, polypropylene, polyethylene terephthalate, polystyrene, polyvinyl chloride, nylon, or polyester. One of these materials can be used alone, or a combination of two or more of these materials can be used to form a multilayer structure to improve heat resistance and barrier properties. Furthermore, the shape of the container or bag is not particularly limited, but from the viewpoint of improving heat exchange efficiency, a shape that ensures a large surface area is preferred.

[0092] Furthermore, it is preferred that the storage materials P1 and P2 are at least one of latent heat storage material and cold storage material, respectively. Latent heat storage material or cold storage material refers to a material that utilizes the thermal energy accompanying the phase change of the heat storage component or cold storage component. It is a material that utilizes the thermal energy absorbed when the phase of the heat storage component or cold storage component changes from a solid state (solid) to a molten state (liquid), or the thermal energy released when the phase of the heat storage component or cold storage component changes from a molten state (liquid) to a solid state (solid).

[0093] The solidification / melting temperature of a heat storage component or cold storage component refers to the temperature at which its phase changes from a solid state (solid) to a molten state (liquid), or from a molten state (liquid) to a solid state (solid). In this specification, the "melting temperature" of a cold storage material composition refers to "the temperature exhibited by the cold storage material composition when it melts and liquefies in its solid state." More specifically, using... Figure 2 Let's explain the "melting temperature" mentioned above. Figure 2 This is a graph obtained by plotting the temperature of the cold storage material composition relative to time after placing the solidified cold storage material composition in a constant temperature bath and allowing the temperature of the bath to rise from an extremely low temperature at a constant rate. For example... Figure 2 As shown, compared to the temperature of the constant-temperature bath which rises at a constant rate, the temperature of the cold storage material composition changes sequentially according to the following (1) to (3): (1) it rises at a constant rate; (2) it remains almost unchanged at temperature T1 due to the latent heat of the cold storage material composition, and remains constant from temperature T1 to temperature T2; (3) it begins to rise again with temperature T2 as the boundary. In this specification, temperature T1 is referred to as the "melting start temperature" and temperature T2 is referred to as the "melting end temperature". The temperature T3, the midpoint between temperature T1 and temperature T2, is defined in this specification as the "melting temperature".

[0094] Phase usually refers to the three phases of a substance: solid, liquid, and gas. However, in this embodiment, the solid and liquid phases are used. The phase of the heat storage component or cold storage component refers to the phase of 50% or more by weight. For example, the phase of the heat storage component is solid (solidified state) where 80% by weight is in a solid state and 20% by weight is in a liquid state.

[0095] The composition constituting the latent heat storage component or cold storage component used in this embodiment is not particularly limited. Examples include inorganic hydrate salts such as calcium chloride hexahydrate, sodium sulfate decahydrate, sodium acetate trihydrate, potassium chloride hexahydrate, and quaternary ammonium salt hydrate; at least one higher alkane selected from the group consisting of straight-chain and branched alkanes with 9 to 30 carbon atoms, such as n-tetradecane, n-hexadecane, n-heptadecane, n-dodecane, and n-dodecane; saturated fatty acids with 6 to 18 carbon atoms, such as octanoic acid, decanoic acid, lauric acid, dodecanoic acid, and stearic acid; and fatty acid esters such as methyl laurate, methyl myristate, and butyl stearate. Compositions of organic compounds for heat storage materials, including palmitic acid, oleic acid, linoleic acid, unsaturated fatty acids with 6 to 18 carbon atoms and their ester compounds, 1-decyl alcohol, 2-decyl alcohol, undecyl alcohol, lauryl alcohol, tridecyl alcohol, myristyl alcohol, pentadecyl alcohol, cetyl alcohol, heptadecanol, stearyl alcohol, nonadecanol, eicosyl alcohol, docosyl alcohol, carnauba palmitol, wax alcohol, transoleyl alcohol, l-menthol, etc., monohydric alcohols with 6 or more carbon atoms (i.e., higher alcohols, including any one of straight-chain alcohols, branched-chain alcohols, primary alcohols, secondary alcohols, and tertiary alcohols), dihydric alcohols such as polyethylene glycol and polybutylene glycol (i.e., polyalkylene glycols), etc., can also be used, or mixtures of one or more of these compounds.

[0096] In addition, examples include substances whose main component is water, such as calcium chloride aqueous solution, calcium bromide aqueous solution, potassium bicarbonate aqueous solution, potassium chloride aqueous solution, ammonium chloride aqueous solution, and sodium chloride aqueous solution, as well as substances containing water and highly absorbent polymers.

[0097] exist Figure 1 The constant-temperature conveying container 10 shown contains two types of heat storage materials, P1 and P2 (one or both of the heat storage material and the cold storage material). However, in the constant-temperature conveying container according to this embodiment, it is also possible to contain and configure one type of heat storage material and / or cold storage material (one or both of the heat storage material and the cold storage material). In cases where the outside air temperature is lower than the managed temperature, such as in winter, materials that are in a molten state and are temperature-controlled at a temperature higher than the solidification / melting temperature of the heat storage material and / or cold storage material are contained. In this case, the heat storage material and / or cold storage material are cooled by the outside air temperature, causing a temperature drop and a phase change from a molten state (liquid) to a solidified state (solid), thereby releasing heat energy. This prevents the temperature-maintaining article from being exposed to the outside air and maintains it within a specified temperature range.

[0098] On the other hand, in situations where the outside air temperature is higher than the managed temperature, such as in summer, materials are placed at a temperature lower than the solidification / melting temperature of the heat storage and / or cold storage materials and are in a solidified state. In this case, the heat storage and / or cold storage materials are heated by the outside air temperature, causing their temperature to rise and undergo a phase change from a solidified state (solid) to a molten state (liquid), thus absorbing heat energy. This prevents the temperature-maintaining item from being exposed to the outside air and maintains it within a specified temperature range.

[0099] When using a heat storage material and / or cold storage material composed of one of the above-mentioned types, the release / absorption of latent heat energy by the heat insulation component constituting the constant-temperature conveying container can suppress the effects of temperature rise and fall caused by the temperature difference with the outside air, and maintain the temperature within a specified range for a certain period of time. However, it is troublesome to pre-adjust the heat storage material and / or cold storage material to a specified temperature relative to the external ambient temperature, and there is a tendency for the quantity / weight of heat storage material and cold storage material used to increase in order to maintain the temperature for a long time.

[0100] Alternatively, in this embodiment, multiple heat storage materials with different melting temperature ranges can also be used. In the constant-temperature conveying container involved in this embodiment, such as... Figure 1 As shown, it is possible to store two or more heat storage materials and / or cold storage materials with different solidification / melting states relative to storage materials P1 and P2. For example, when using a first heat storage material or cold storage material (a) and a second heat storage material or cold storage material (b) to maintain the same temperature control conditions throughout the year regardless of the outside air temperature, the following combination of storage materials P1 and P2 is illustrated. An example is a combination in which storage material P1, located near the temperature-maintaining item, stores a first heat storage material or cold storage material (a) whose solidification / melting temperature is near the control temperature and is in a molten state, and storage material P2, located on the outer periphery of the first heat storage material or cold storage material (a), stores a second heat storage material or cold storage material (b) whose solidification / melting temperature is below 0°C and is in a solidified state.

[0101] Alternatively, when using a first heat storage material or cold storage material (a) and a second heat storage material or cold storage material (b), the first heat storage material or cold storage material (a) can be conditioned to a molten state at a temperature higher than the control temperature, and the second heat storage material or cold storage material (b) can be solidified at a temperature below its melting temperature. In this case, the first heat storage material or cold storage material (a) is housed in the storage material P1 near the temperature-maintaining article, and the second heat storage material or cold storage material (b) is housed in the storage material P2. Furthermore, the second heat storage material or cold storage material (b) disposed outside the first heat storage material or cold storage material (a) functions as a heat buffer material relative to the outside air temperature to maintain the temperature of the temperature-maintaining article within the desired temperature range.

[0102] When using two or more heat storage materials and / or cold storage materials with different solidification and melting states, the heat insulation component constituting the container can act as a heat buffer material by using a first heat storage material disposed adjacent to the temperature-keeping article or a second heat storage material or cold storage material (b) disposed outside the cold storage material (a). This can suppress the effects of temperature rise and fall caused by temperature difference with the outside air. Through the temperature interaction between the first heat storage material or 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 melting state is cooled, resulting in a temperature drop and a phase change from the melting state (liquid) to the solidification state (solid), thereby releasing heat energy. This can protect the temperature-keeping article from the influence of both higher and lower temperatures. As a result, the amount of heat storage material or cold storage material used can be reduced, and the temperature-keeping article can be maintained within the specified temperature range for a longer period of time.

[0103] When using two or more heat storage materials and / or cold storage materials with different solidification and melting states, as a specific example, the heat storage material or cold storage material whose melting temperature is adjusted to around 5°C or 20°C is contained in the housing material P1, and the heat storage material or cold storage material whose melting temperature is adjusted to 0°C is contained in the housing material P2.

[0104] Furthermore, the storage materials P1 and P2 are not particularly limited as long as they are shaped to be inserted from the sides of the side panels 1 to 4. For example, the storage materials P1 and P2 may be heat storage materials and / or cold storage materials obtained by containing a heat storage component and / or cold storage component in a long container that is accommodated in the storage part of the side panel.

[0105] From the viewpoint of the versatility of heat storage materials and / or cold storage materials, it is preferable that the housing materials P1 and P2 are a connector formed by linking multiple heat storage materials and / or cold storage materials. This improves the workability of housing materials P1 and P2 during encapsulation and allows for the construction of housing materials P1 and P2 for each of multiple constant-temperature delivery containers of different sizes. The result is increased versatility of housing materials P1 and P2.

[0106] [Implementation Method 2]

[0107] Another embodiment of the present invention will be described below. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0108] Figure 3 This is a perspective view showing the outline structure of the constant-temperature conveying container 10A according to this embodiment. Furthermore, in Figure 3 For simplicity, the storage section 1a, storage section 2a, and top panel 6 are omitted.

[0109] like Figure 3 As shown, the structure of the fitting corner 7A of the constant temperature conveying container 10A in this embodiment differs from that in Embodiment 1. For example... Figure 3 As shown, the fitting corner portion 7A is composed of multiple components and can be assembled. More specifically, the fitting corner portion 7A is composed of components 71, 72, and 73 and can be assembled. Components 71, 72, and 73 are each rectangular parallelepiped in shape.

[0110] The fitting corner portion 7A is an assembly of components 71, 72, and 73, forming a space within the insertion corner portion Y formed by side surface 1c and side surface 2c. Components 71, 72, and 73 are fitted into the insertion corner portion Y in a manner coplanar with side wall panels 1 and 2. Fitting protrusions 71e and 71e are provided on the surfaces of component 71 opposite to side surfaces 1c and 2c, respectively. Similarly, fitting protrusions 72e and 72e are provided on the surfaces of component 72 opposite to side surfaces 1c and 2c, respectively. Furthermore, fitting protrusions 73e and 73e are provided on the surfaces of component 73 opposite to side surfaces 1c and 2c, respectively. The fitting protrusions 71e, 71e, 72e, 72e, 73e, and 73e engage with the fitting recesses 1e and 2e of the side wall panels 1 and 2, respectively.

[0111] When components 71, 72, and 73 are assembled, viewed from above, the mating protrusions 71e, 72e, and 73e are positioned in overlapping positions. Therefore, when components 71, 72, and 73 are assembled, the mating protrusions 71e, 72e, and 73e engage with each other, forming a ridge extending in the vertical direction.

[0112] According to the constant-temperature conveying container 10A of this embodiment, it is possible to prevent the inflow of external air into the side wall panels 1 to 4, and to efficiently encapsulate and store materials (heat storage materials or cold storage materials) relative to the side wall panels 1 to 4. In particular, in the constant-temperature conveying container 10A, the fitting corner portion 7A can be miniaturized and lightened into components 71, 72, and 73. Therefore, the fitting operation of the fitting corner portion 7A can be performed using miniaturized and lightweight components 71, 72, and 73, and the fitting operation of the fitting corner portion 7A is made more efficient.

[0113] [Implementation Method 3]

[0114] Another embodiment of the present invention will be described below. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0115] Figure 4 This is a perspective view showing the outline structure of the constant-temperature conveying container 10B according to this embodiment. Furthermore, in Figure 4 For simplicity, the storage section 1a, storage section 2a, and top panel 6 are omitted.

[0116] like Figure 4 As shown, the structures of the fitting recesses 1e and 2e and the fitting corner portion 7B of the constant temperature conveying container 10B involved in this embodiment are different from those in Embodiment 1. For example... Figure 4 As shown, the fitting recess 1e is provided at the outermost end of the side surface 1c of the side wall panel 1, and no side wall is formed on the outer side of the fitting recess 1e. In addition, the fitting recess 2e is provided at the outermost end of the side surface 2c of the side wall panel 2, and no side wall is formed on the outer side of the fitting recess 2e.

[0117] The fitting corner portion 7B is composed of multiple components and is assembleable. The fitting corner portion 7B is composed of components 74 and 75 and is assembleable. Components 74 and 75, when assembled into the fitting corner portion 7B, are accommodated in the space formed by side surface 1c and side surface 2c within the insertion corner portion Y. The fitting corner portion 7B is fitted into the insertion corner portion Y in a manner coplanar with the side wall panels 1 and 2.

[0118] Component 74 is a cuboid rod shape. Component 74 has sides 74a and 74b. When the fitting corner 7B is fitted with sides 1c and 2c, sides 74a and 74b abut against sides 1c and 2c, respectively.

[0119] Component 75 has mating protrusions 75e and 75e on its surfaces opposite to sides 1c and 2c, respectively. The mating protrusions 75e and 75e are protruding strips extending in the vertical direction and mating with mating recesses 1e and 2e, respectively. Component 75 also has abutting surfaces 75a and 75a extending in the vertical direction. When the mating corner 7B is mated with sides 1c and 2c, the abutting surfaces 75a and 75a abut with sides 1c and 2c, respectively. Additionally, component 75 has abutting recesses 75b that abut with the sides of component 74. When the sides of component 74 abut with the abutting recesses 75b, one abutting surface 75a is coplanar with side 74a, and the other abutting surface 75a is coplanar with side 74b.

[0120] According to the constant temperature conveying container 10B of this embodiment, it is possible to prevent the inflow of external air into the side wall panels 1 to 4, and to efficiently encapsulate and store materials (heat storage materials or cold storage materials) relative to the side wall panels 1 to 4.

[0121] Furthermore, in the constant-temperature conveying container 10B, in order to engage the fitting recess 1e with one of the fitting protrusions 75e, the fitting corner portion 7B is moved from the side side of the constant-temperature conveying container 10B in a manner close to the side side 1c. Therefore, if the fitting recess 1e engages with one of the fitting protrusions 75e, the fitting recess 2e and the other fitting protrusion 75e can also engage with each other. That is, the fitting corner portion 7B is configured to be inserted and engaged from the side side of the constant-temperature conveying container 10B. Therefore, according to the constant-temperature conveying container 10B, the engagement operation of the fitting corner portion 7B is highly efficient.

[0122] Furthermore, in the constant-temperature conveying container 10B according to this embodiment, the side wall panels 1 and 4 are connected to each other by a concave-convex fitting structure on the side 1d opposite to the insertion corner Y and the side 4d opposite to the insertion corner Z. More specifically, a fitting protrusion 1f is provided on the side 1d. This fitting protrusion 1f is a protrusion extending in the vertical direction. Furthermore, a fitting recess 4f is formed in the portion near the side 4d of the side wall panel 4, that is, the portion of the side wall panel 4 opposite to the side 1c, to fit with the fitting protrusion 1f. The fitting recess 4f is a groove extending in the vertical direction.

[0123] Similarly, on side 2d opposite to the insertion corner Y and side 3d opposite to the insertion corner Z, side wall panels 2 and 3 are connected to each other by a concave-convex fitting structure. A fitting protrusion 3f is provided on side 3d. Furthermore, a fitting recess 2f is formed in the portion near side 2d of side wall panel 2, that is, the portion of side wall panel 2 opposite to side 3c, to fit with the fitting protrusion 3f. The fitting protrusion 3f is a raised strip extending in the vertical direction, and the fitting recess 2f is a groove extending in the vertical direction.

[0124] [Implementation Method 4]

[0125] Another embodiment of the present invention will be described below. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0126] Figure 5 This is a perspective view showing the outline structure of the constant-temperature conveying container 10C according to this embodiment. Furthermore, in Figure 5 For simplicity, the storage section 1a, storage section 2a, and top panel 6 are omitted.

[0127] like Figure 5 As shown, the structure of the fitting corner 7C of the constant temperature conveying container 10C in this embodiment differs from that in Embodiment 1. For example... Figure 5 As shown, the fitting corner portion 7C is composed of multiple parts and can be assembled. More specifically, the fitting corner portion 7C is composed of parts 76 and 77 and can be assembled.

[0128] The fitting corner portion 7C is an assembly of components 76 and 77, forming a space accommodated in the insertion corner portion Y by the space formed by side surface 1c and side surface 2c. Components 76 and 77 are columnar in shape, extending vertically. Component 76 has a fitting portion 76a, side surfaces 76b and 76c, and a fitting protrusion 76e. Component 77 has a fitting portion 77a, side surfaces 77b and 77c, and a fitting protrusion 77e. Components 76 and 77 are connected to each other by the interlocking of fitting portions 76a and 77a. Furthermore, when components 76 and 77 are fitted together, side surface 76c and side surface 77b are coplanar. Additionally, the fitting protrusion 76e of component 76 fits into the fitting recess 1e of the side wall panel 1. On the other hand, the fitting protrusion 77e of component 77 fits into the fitting recess 2e of the side wall panel 2.

[0129] When the fitting corner 7C is fitted with the sides 1c and 2c, the side 76b of component 76 abuts against the side 1c of the side wall panel 1. In addition, the side 76c of component 76 and the side 77b of component 77 abut against the side 2c of the side wall panel 2.

[0130] According to the constant temperature conveying container 10C of this embodiment, it is possible to prevent the inflow of external air into the side wall panels 1 to 4, and to efficiently encapsulate and store materials (heat storage materials or cold storage materials) relative to the side wall panels 1 to 4.

[0131] Specifically, according to the constant temperature conveying container 10C, the fitting corner portion 7C is composed of a component 76 having a fitting protrusion 76e that fits into the fitting recess 1e and a component 77 having a fitting protrusion 77e that fits into the fitting recess 2e. Moreover, the component 76 and the component 77 can be assembled by fitting the fitting portions 76a and 77a. In this way, by designing the components constituting the fitting corner portion 7C as component 76 fitting into side 1c and component 77 fitting into side 2c, the fitting operation of the fitting corner portion 7C is made more efficient.

[0132] For example, the following fitting operation can be performed. First, component 76 is moved from the side towards side 1c, so that component 76 fits into side 1c. Next, component 77 is moved from the side towards side 2c, so that component 77 fits into side 2c, and components 76 and 77 are connected by the fitting of fitting portions 76a and 77a. In this way, during the fitting operation at the fitting corner 7C, components 76 and 77 can be fitted from the side of the constant temperature conveying container 10C to sides 1c and 2c, respectively. Therefore, the fitting operation at the fitting corner 7C is highly efficient.

[0133] [Implementation Method 5]

[0134] Another embodiment of the present invention will be described below. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0135] Figure 6 This is a perspective view showing the outline structure of the constant-temperature conveying container 10D according to this embodiment. Furthermore, in Figure 6 For simplicity, the storage section 1a, storage section 2a, and top panel 6 are omitted.

[0136] like Figure 6 As shown, the structure of the fitting corner 7D of the constant temperature conveying container 10D in this embodiment differs from that in Embodiment 1. For example... Figure 6 As shown, the fitting corner portion 7D is composed of multiple components and can be assembled. More specifically, the fitting corner portion 7D is composed of components 78a and 78b and component 79 and can be assembled. In the insertion corner portion Y, three fitting recesses 1e are formed on the side surface 1c in a vertically arranged manner. In addition, two fitting recesses 2e are formed on the side surface 2c in a vertically arranged manner.

[0137] The fitting corner portion 7D is an assembly of components 78a and 78b and component 79, forming a structure that accommodates the space formed by side surface 1c and side surface 2c within the insertion corner portion Y. Components 78a and 78b are rectangular parallelepipeds that are elongated in the horizontal direction. In the horizontal direction of the side wall panel 2, components 78a and 78b are respectively fitted into the fitting recess 2e.

[0138] Component 79 is a column shape extending vertically. Component 79 has sides 79a and 79b, horizontal grooves 79c and 79d, and three fitting protrusions 79e. When the fitting corner 7D is fitted with sides 1c and 2c, sides 79a and 79b abut against sides 1c and 2c, respectively. Furthermore, the fitting protrusions 79e fit into the fitting recesses 1e of side 1c. The three fitting protrusions 79e are formed in a vertically arranged manner. Moreover, three fitting recesses 1e are formed corresponding to the three fitting protrusions 79e.

[0139] Horizontal grooves 79c and 79d are grooves extending horizontally along the sidewall panel 2. Horizontal grooves 79c and 79d are respectively formed to connect with two fitting recesses 2e. The side surface of component 78a slides without clearance in the horizontal direction of the sidewall panel 2 relative to the entire side surface of horizontal groove 79c. Similarly, the side surface of component 78b slides without clearance in the horizontal direction of the sidewall panel 2 relative to the entire side surface of horizontal groove 79d. Therefore, components 78a and 78b respectively pass through the horizontal grooves 79c and 79d of component 79 to fit into the fitting recesses 2e.

[0140] According to the constant temperature conveying container 10D of this embodiment, it is possible to prevent the inflow of external air into the side wall panels 1 to 4, and to efficiently encapsulate and store materials (heat storage materials or cold storage materials) relative to the side wall panels 1 to 4.

[0141] Specifically, according to the constant temperature conveying container 10D, the fitting corner 7D is composed of components 78a and 78b that fit into the fitting recess 2e and component 79 having a fitting protrusion 79e that fits into the fitting recess 1e. Furthermore, components 78a and 78b can be assembled with component 79 via horizontal grooves 79c and 79d. In this way, by designing the components constituting the fitting corner 7D as component 79 fitting into side 1c and components 78a and 78b fitting into side 2c, the fitting operation of the fitting corner 7D is made more efficient.

[0142] For example, the following fitting operation can be performed. First, component 79 is moved from the side towards side 1c, so that component 79 fits into side 1c. Next, components 78a and 78b are moved from the side through the horizontal grooves 79c and 79d of component 79, respectively, towards side 2c, so that components 78a and 78b fit into side 2c. In this way, during the fitting operation at the fitting corner 7D, components 79 and components 78a and 78b can be fitted from the side of the constant temperature conveying container 10D into sides 1c and 2c, respectively. Therefore, the fitting operation at the fitting corner 7D is highly efficient.

[0143] Furthermore, in the constant temperature conveying container 10D according to this embodiment, an insertion port 6b (second insertion port) is provided on the top panel 6. Figure 7 This is a front view showing the outline structure of the constant-temperature conveying container 10D according to this embodiment. Furthermore, Figure 7 This is the front view viewed from the horizontal direction of side wall panels 2 and 4 when side wall panel 1 is removed.

[0144] like Figure 7 As shown, in the constant-temperature conveying container 10D according to this embodiment, the insertion port 6b is an opening for inserting storage material (heat storage material or cold storage material), and it communicates with the storage portion 6a (second receiving portion) of the top panel 6. That is, for the constant-temperature conveying container 10D, in addition to the side wall panels 1 to 4, storage material can also be inserted from the side relative to the top panel 6. Therefore, in the constant-temperature conveying container 10D, storage material can be inserted from the side relative to the top panel 6. Furthermore, Figure 7 The structure shown can also be applied to the constant-temperature conveying containers 10 and 10A to 10C described in embodiments 1 to 4 above. Furthermore, the storage portion 6a and the insertion port 6b are the same as those provided in the constant-temperature conveying container 10E described in embodiment 6 below. Therefore, for details regarding the storage portion 6a and the insertion port 6b, please refer to embodiment 6 below.

[0145] [Implementation Method 6]

[0146] Another embodiment of the present invention will be described below. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0147] Figure 8 This is an exploded perspective view showing the outline structure of the constant temperature transport container 10E according to this embodiment.

[0148] like Figure 8As shown, the connection between the side wall panels 2 and 4 and the top panel 6 of the constant temperature conveying container 10E according to this embodiment differs from that in embodiments 1 to 5 described above. The top panel 6 has a storage portion 6a for storing heat storage material and an insertion port 6b (second insertion port) for inserting the heat storage material into the storage portion 6a. The insertion port 6b is formed on both the side surface 6f of the top panel 6 and the side surface (not shown) opposite to the side surface 6f. Furthermore, the insertion port 6b only needs to be formed on at least one side surface of the top panel 6.

[0149] In this way, in the constant temperature delivery container 10E, an insertion port 6b is formed on the side 6f of the top panel 6, and a storage portion 6a (second storage portion) communicating with the insertion port 6b extends to the side. Therefore, when assembling the constant temperature delivery container 10E, heat storage material can be inserted from the side relative to the top panel 6.

[0150] In the constant-temperature conveying container 10E, the top panel 6 and the side wall panels 1-4 form a second insertion corner for heat storage material. This second insertion corner is formed by a side surface 6f of the top panel 6 with an insertion port 6b and the upper surface 2g of the side wall panel 2 adjacent to the side surface 6f. Furthermore, in this second insertion corner, the insertion port 6b is exposed to the outside. Additionally, although in Figure 8 The second insertion corner is formed on the upper surface of the side panel 4 of the top panel 6, which also has an insertion opening 6b, on the side opposite to the side panel 6f, and on the side wall panel 4 adjacent to the side opposite to that side.

[0151] Furthermore, in the constant temperature conveying container 10E, a fitting corner portion 8 (second fitting corner portion) is provided at the aforementioned second insertion corner. The fitting corner portion 8 has a structure that closes the insertion port 6b and fits into at least one of the side surface 6f where the insertion port 6b is provided and the upper surface 2g of the side wall panel 2. Specifically, a fitting recess 2h is provided on the upper surface 2g of the side wall panel 2. Similarly, a fitting recess 4g is provided on the upper surface of the side wall panel 4. The fitting recesses 2h and 4g are grooves that extend in the horizontal direction along the side wall panels 2 and 4, respectively.

[0152] The fitting corner portion 8 has a shape that accommodates the space formed by the side surface 6f and the upper surface 2g within the second insertion corner portion. The fitting corner portion 8 fits into the second insertion corner portion in a manner that is coplanar with the side wall panel 2 and the top panel 6. A fitting protrusion 8f is provided on the surface of the fitting corner portion 8 opposite to the upper surface 2g, which fits into the fitting recess 2h. The fitting protrusion 8f is a protruding strip that extends horizontally along the side wall panel 2. By fitting the upper surface 2g of the side wall panel 2 into the second insertion corner portion, the insertion opening 6b is closed. As a result, it is possible to prevent the inflow of external air into the receiving portion of the top panel 6.

[0153] Furthermore, the fitting corner portion 8 can also be configured to fit into the side surface 6f of the top panel 6. Additionally, the fitting corner portion 8 can also be configured to fit into the side wall panel 3 adjacent to the side wall panel 2. For example... Figure 8 As shown, a fitting protrusion 3g is formed on the surface of the side wall panel 3 opposite to the fitting corner portion 8. The fitting protrusion 3g is a protruding strip that extends in the vertical direction. A fitting recess (not shown) is formed in the fitting corner portion 8 as a groove that fits into the fitting protrusion 3g.

[0154] According to the constant temperature conveying container 10E involved in this embodiment, the following effects are achieved during the assembly of the constant temperature conveying container 10E.

[0155] That is, in the assembly method of the constant temperature delivery container 10E, after the container body is manufactured by erecting four side wall panels 1 to 4 relative to the bottom panel 5, the top panel 6 is connected to the upper end of the container body. The second insertion corner is formed with the top panel 6 connected in this manner. Therefore, the user does not need to lift the very heavy top panel 6, which is encapsulated with heat storage material, to connect to the upper end of the container body. The user only needs to connect the lighter top panel 6, which is not encapsulated with heat storage material, to the upper end of the container body. Moreover, the heat storage material can be encapsulated in the top panel 6 simply by inserting it into the insertion port 6b after connecting the top panel 6. Therefore, according to the structure of the constant temperature delivery container 10E, the burden on the user caused by assembling the top panel 6 can be reduced.

[0156] Furthermore, after encapsulating the heat storage material in the top panel 6, the fitting corner 8 is fitted into the second insertion corner, thereby completing the constant temperature delivery container 10E.

[0157] Alternatively, a handle may be provided at the fitting corner portion 8. For example, when disassembling the constant temperature delivery container 10E, the user can use this handle to pull out the fitting corner portion 8 from the side panel 2 and the top panel 6. As a result, the disassembly of the constant temperature delivery container 10E becomes easier.

[0158] [Purpose of Embodiments 7-10 of the present invention]

[0159] Based on the structures of embodiments 1 to 6 described above, the constant temperature conveying container according to embodiments 7 to 10 of the present invention further includes a structure in which adjacent heat storage material receiving portions in the vertical direction have communication holes that connect them to each other.

[0160] Here, compared with the constant temperature conveying container with a longitudinal placement structure described in Patent Documents 3 and 4, the constant temperature conveying container with a transverse placement structure described in Patent Document 5 is advantageous in terms of operability in easily accommodating the heat storage material in the side wall panel.

[0161] However, while the workability of the transversely placed constant-temperature conveying container is better than that of the longitudinally placed constant-temperature conveying container, the inventors' research has revealed a new problem: a shorter temperature holding time inside the constant-temperature conveying container.

[0162] The purpose of embodiments 7 to 10 of the present invention is to realize a constant temperature conveying container that, in addition to the effects of embodiments 1 to 6 described above, can also improve the workability related to the containment of heat storage material to the side wall panel and extend the temperature holding time inside the container.

[0163] [Summary of Embodiments 7-10 of the Invention]

[0164] As a result of further research on the transversely placed constant-temperature conveying container, the inventors of this application have independently discovered a new problem: compared to the longitudinally placed constant-temperature conveying container, the transversely placed constant-temperature conveying container has a shorter temperature-holding time for the item. This problem related to the temperature-holding time of the transversely placed constant-temperature conveying container is entirely new and has not been recognized in the technical field to which this application pertains. Therefore, the inventors of this application have conducted in-depth development with the goal of creating a transversely placed constant-temperature conveying container with a longer temperature-holding time.

[0165] As a result, the inventors of this application discovered a new insight: by providing interconnecting holes to adjacent heat storage material receiving sections in the vertical direction, not only is workability improved, but surprisingly, the temperature holding time is also significantly better than that of a constant-temperature conveying container with a longitudinal placement structure. Furthermore, based on this new insight, a constant-temperature conveying container of this embodiment was completed.

[0166] That is, the constant-temperature conveying container according to embodiments 7 to 10 of the present invention is an assembled constant-temperature conveying container capable of conveying temperature-maintaining articles at a constant temperature, comprising a side wall panel, a top panel, and a bottom panel, and having the following characteristics. Specifically, based on the structure of embodiments 1 to 6 described above, the side wall panel comprises a receiving portion for housing heat-storing material and an insertion port for inserting heat-storing material into the receiving portion from one side of the side wall panel. Multiple receiving portions are arranged in a vertical direction, and adjacent receiving portions in the vertical direction have communicating holes that connect them to each other.

[0167] According to the above structure, multiple heat storage material receiving sections are arranged and configured in the vertical direction, and adjacent heat storage material receiving sections in the vertical direction have communication holes that connect them to each other. Therefore, according to the above structure, the workability related to the reception of heat storage material into the side wall panel is improved, and the temperature retention time inside the container is extended.

[0168] [Implementation Method 7]

[0169] Hereinafter, Embodiment 7 of the present invention will be described in detail. Figure 9 This is an exploded perspective view showing the outline structure of the constant temperature transport container 10F according to Embodiment 7 of the present invention.

[0170] like Figure 9 As shown, similar to embodiments 1 to 6, the constant temperature conveying container 10F involved in this embodiment has a structure in which the fitting corner portions 7 and 7 are respectively fitted into the insertion corner portions Y and Z.

[0171] Furthermore, the structure of the side wall panels 1, 2, 3, and 4 of the constant-temperature conveying container 10F according to this embodiment differs from that of embodiments 1 to 6. The side wall panels 1, 2, 3, and 4 each have panel bodies 11, 21, 31, and 41 that are rectangular plates. The panel bodies 11, 21, 31, and 41 are separable from each other. Here, the bottom panel 5 side is positioned as the lower side, and the top panel 6 side is positioned as the upper side, relative to the side wall panels 1, 2, 3, and 4. In the side wall panels 1, 2, 3, and 4, inner structural portions 11A, 21A, 31A, and 41A are respectively provided in the panel bodies 11, 21, 31, and 41.

[0172] Next, the structure of side wall panels 1 to 4 will be described. Furthermore, the following description will focus on the structure of side wall panel 1. Since the structure of side wall panels 2 to 4 is the same as that of side wall panel 1, descriptions will be omitted. Figure 10 1001 is an exploded perspective view showing the outline structure of the side wall panel 1. Figure 10 1002 is a perspective view showing the outline of the appearance of the side wall panel 1. Additionally, Figure 11 This is a front view showing the internal structure of the side wall panel 1 as viewed from the inside.

[0173] like Figure 10 1001 and 1002 and Figure 11 As shown, the side wall panel 1 includes: receiving portions S1 to S3 for receiving receiving materials P1 and P2 as heat storage materials; and insertion ports B1 to B3 for inserting receiving materials P1 and P2 into receiving portions S1 to S3 respectively. Insertion ports B1 to B3 are respectively formed on one side 1c of the side wall panel 1.

[0174] The storage materials P1 and P2 are heat storage materials with different melting temperature ranges. In addition, the storage materials housed in the housing sections S1 to S3 can also be heat storage materials with the same melting temperature range.

[0175] Furthermore, in each of the storage sections S1 to S3, multiple storage materials P1 and P2 are arranged side by side in the horizontal direction, overlapping in the thickness direction. Alternatively, each of the storage sections S1 to S3 may contain only one storage material.

[0176] More specifically, the side wall panel 1 includes a panel body 11, an inner structural part 11A, a closing member 16, and a protective member 17. The inner structural part 11A is provided on the inner surface of the panel body 11. The inner structural part 11A includes a support part 12, a lower track part 13, a middle track part 14, and an upper track part 15.

[0177] The support column 12 is configured to protrude inward from the inner side of the panel body 11 and is located on the side opposite to the side 1c. In addition, the support column 12 is a column shape that extends along the height direction.

[0178] The lower track section 13, the middle track section 14 and the upper track section 15 extend horizontally from the support section 12 toward the side 1c.

[0179] The storage materials P1 and P2, inserted through the insertion ports B1 to B3, slide along the lower track section 13, the middle track section 14, and the upper track section 15. The lower track section 13, the middle track section 14, and the upper track section 15 function as guide tracks to guide the storage materials P1 and P2 into the side wall panel 1.

[0180] In the height direction, the lower track section 13, the middle track section 14, and the upper track section 15 are equally spaced from each other. This spacing only needs to be larger than the height dimension of the materials P1 and P2. Furthermore, in the height direction, the distance between the upper end of the support column 12 and the upper track section 15 only needs to be larger than the height dimension of the materials P1 and P2. With this structure, the materials P1 and P2 can be accommodated in the space between the lower track section 13 and the middle track section 14, the space between the middle track section 14 and the upper track section 15, and the space above the upper track section 15. In addition, a top panel 6 (not shown) is provided on the upper end of the support column 12 to enclose the space formed by the side of the support column 12 and the upper surface of the upper track section 15.

[0181] Furthermore, the sealing member 16 is a member that seals the insertion ports B1 to B3 from the side 1c. The structure of the sealing member 16 is not particularly limited as long as it can seal the insertion ports B1 to B3. From the viewpoint of preventing air inside the receiving parts S1 to S3 from leaking to the outside of the side wall panel 1, it is preferable that the sealing member 16 has a structure that fits into the insertion ports B1 to B3 in the side wall panel 1.

[0182] Furthermore, the protective component 17 is a sheet material that covers the support portion 12, lower track portion 13, middle track portion 14, and upper track portion 15 of the panel body 11 from the inside. The protective component 17 is inserted between the temperature-maintaining item and the storage materials P1 and P2 inside the constant temperature conveying container 10. The protective component 17 serves to prevent the storage materials P1 and P2 from falling towards the temperature-maintaining item and to prevent the temperature-maintaining item from directly contacting the storage materials P1 and P2. Examples of protective components 17 include corrugated cardboard, thick paper, and plastic sheets.

[0183] In the side wall panel 1, the receiving section S1 has a space formed by the upper surface of the lower track section 13, the lower surface of the middle track section 14, the side of the support section 12, the closing member 16, and the protective member 17, and the receiving section S2 contains materials P1 and P2. Similarly, the receiving section S2 has a space formed by the upper surface of the middle track section 14, the lower surface of the upper track section 15, the side of the support section 12, the closing member 16, and the protective member 17, and the receiving section S3 has a space formed by the upper surface of the upper track section 15, the top panel 6, the side of the support section 12, the closing member 16, and the protective member 17, and the receiving section S3 contains materials P1 and P2. For example, in the receiving section S3, storage materials P1 and P2 are inserted one group at a time through the insertion port B1, and the storage materials P1 and P2 slide on the upper track section 15 to move horizontally toward the support section 12, thereby storing multiple storage materials P1 and P2 in the receiving section S3.

[0184] In the constant-temperature transport container 10F according to this embodiment, a plurality of receiving portions S1 to S3 are arranged vertically relative to each other. Moreover, adjacent receiving portions S1 and S2 in the vertical direction have communication holes 18 that connect them to each other. Similarly, adjacent receiving portions S2 and S3 in the vertical direction have communication holes 18 that connect them to each other.

[0185] like Figure 10 1001 and Figure 11As shown, the connecting hole 18 extends along the thickness direction of the side wall panel 1 and connects adjacent receiving portions S1 and S2 in the vertical direction to each other, or receiving portions S2 and S3 to each other. Moreover, among the multiple receiving portions S1 to S3 arranged and configured in the vertical direction, these connecting holes 18 are configured to overlap each other when viewed from the vertical direction.

[0186] In existing temperature-controlled conveyor containers with a longitudinal insertion structure, storage materials need to be inserted from above the side panel. Therefore, if the size of the temperature-controlled conveyor container increases, the height of the side panel increases, making it difficult for users to store the materials. This is especially problematic for shorter women assembling the container, as their line of sight and hands cannot easily reach the insertion point on the side panel, making it difficult to store the materials. Furthermore, after inserting the materials, moving the side panel becomes very heavy, further complicating the operation.

[0187] On the other hand, the constant-temperature conveying container 10F according to this embodiment is a lateral insertion structure in which the storage materials P1 and P2 are inserted into the insertion ports B1 to B3 provided on the side 1c relative to the side wall panel 1. Therefore, even if the size of the constant-temperature conveying container 10F increases and the height of the side wall panel 1 increases, the insertion ports for storing the storage materials can be easily accessed by the user. As a result, storing the storage materials P1 and P2 into the side wall panel 1 in the constant-temperature conveying container 10F becomes easier. Furthermore, it is not necessary to move the heavy side wall panel 1 after the storage materials P1 and P2 are inserted. As a result, the workload of assembly operations can be reduced, and workability is improved.

[0188] Furthermore, in the constant-temperature transport container 10F according to this embodiment, adjacent receiving portions S1 and S2 (or receiving portions S2 and S3) in the vertical direction have communicating holes 18 that connect them to each other. Therefore, compared with a constant-temperature transport container with a longitudinal insertion structure, the temperature holding time inside the container can be extended.

[0189] As described above, the constant-temperature conveying container 10F according to this embodiment improves workability related to the containment of materials P1 and P2 to the side wall panels 1 to 4 and extends the temperature retention time inside the container.

[0190] Here, the materials used for the panel bodies of the side wall panels 1 to 4, the bottom panel 5, and the top panel 6 in the constant temperature conveying container 10F are not particularly limited as long as they have heat insulation properties, and the materials of the constant temperature conveying container 10 involved in Embodiment 1 can be used.

[0191] Furthermore, in the constant-temperature conveying container 10F according to this embodiment, multiple receiving sections for storing materials may also be provided on the top panel 6. Additionally, the top panel 6 may or may not have connecting holes for communicating with each of the multiple receiving sections.

[0192] <Regarding the housing material (heat storage material) for the top panel and side wall panels of the constant-temperature conveying container according to this embodiment>

[0193] The storage material housed in the side wall panels 1-4 and the top panel 6 is not particularly limited, but it is preferably composed of storage material P1 and storage material P2, which has a lower melting temperature than storage material P1. Furthermore, it is preferable that storage material P2 is overlapped and arranged outside storage material P1 (on the side opposite to the storage compartment) within the housing. Here, the combination of storage materials P1 and P2 is not particularly limited, but it is preferable that the melting temperature range of storage material P1 is adjusted to 5°C and the melting temperature range of storage material P2 is adjusted to 0°C.

[0194] Furthermore, the weight ratio of the storage materials P1 and P2 housed in the side wall panels 1 to 4 and the top panel 6 can be appropriately set according to the environment in which the constant temperature conveying container is installed (e.g., summer, winter), the capacity of the storage chamber, etc. Regarding this weight ratio, when the storage material P1 is set to 1, the storage material P2 is preferably 1.5 or less, more preferably 0.2 to 1.4, and even more preferably 0.8 to 1.3.

[0195] Especially in summer environments, to efficiently transfer the cool air from storage material P2 to storage material P1 through the connecting holes to promote air convection, it is preferable to set the weight ratio of storage materials P1 and P2 as described above. In particular, when the melting temperature range of storage material P1 is adjusted to 5°C and the melting temperature range of storage material P2 is adjusted to 0°C, the weight ratio of storage materials P1 and P2 set as described above is particularly effective.

[0196] Furthermore, the weight of the storage material corresponds to the weight of the heat-storing or cold-storing component contained within it. That is, the weight of the heat-storing or cold-storing component contained within the storage material naturally increases proportionally to the weight of the storage material itself. In other words, the aforementioned weight ratio of storage materials P1 and P2 can be interpreted as the weight ratio of the heat-storing or cold-storing component contained in storage material P1 to the weight ratio of the heat-storing or cold-storing component contained in storage material P2.

[0197] Additionally, a heat-insulating element for regulating heat transfer may be provided between the housing materials P1 and P2. The material of the heat-insulating element is not particularly limited as long as it has heat-insulating properties; foamed plastics and vacuum insulation materials are preferred. Specifically, foamed plastics are materials obtained by foaming polystyrene, polyethylene, polypropylene, polyurethane, or poly(3-hydroxyalkanoate) resins. From the viewpoint of heat insulation performance and cost, foamed polystyrene is preferred. The thickness of the heat-insulating element is preferably 5 mm to 20 mm, and more preferably 8 mm to 12 mm.

[0198] [Implementation Method 8]

[0199] The following describes embodiment 8 of the present invention. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated. Figure 12 This is a front view taken from the inside, showing the internal structure of the side wall panel 1A of the constant temperature conveying container according to Embodiment 8 of the present invention.

[0200] like Figure 12 As shown, the configuration of the connecting holes 18 in the side wall panel 1A of the constant temperature conveying container according to this embodiment is different from that in Embodiment 7 described above. In the multiple receiving portions S1 to S3 arranged in the vertical direction, the connecting holes 18 are configured so that they do not overlap when viewed from the vertical direction.

[0201] Even with this structure, it improves workability related to the containment of materials P1 and P2 to the side wall panels 1-4 and extends the time the temperature inside the container is maintained.

[0202] [Implementation Method 9]

[0203] The following describes embodiment 9 of the present invention. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated. Figure 13 This is a front view taken from the inside, showing the internal structure of the side wall panel 1B of the constant temperature conveying container according to Embodiment 9 of the present invention.

[0204] like Figure 13 As shown, the structure of the lowest-lying housing S1 in the constant-temperature conveying container of this embodiment, which has multiple housing sections S1 to S3 arranged in the vertical direction, differs from that in embodiment 7. The bottom wall of housing section S1 corresponds to the lower track section 13. In the constant-temperature conveying container of this embodiment, housing section S1 has a through hole 18a that penetrates the lower track section 13.

[0205] The through hole 18a is a hole in the side wall panel 1B that communicates with the outside. In the constant temperature transport container according to this embodiment, the receiving portions S1 to S3 of the side wall panel 1B are connected to the storage chamber space of the constant temperature transport container via the through hole 18a. Therefore, air (cold air) in the receiving portions S1 to S3 flows into the storage chamber space of the constant temperature transport container through the through hole 18a.

[0206] The constant-temperature conveying container according to this embodiment is particularly effective when used in environments where the temperature is higher than the management temperature range of the temperature-maintaining item. For example, when the constant-temperature conveying container is used in a high-temperature environment in summer, air in the housing sections S1 to S3 flows into the storage chamber space through the through-hole 18a, thereby preventing the temperature inside the storage chamber from exceeding the upper limit temperature of the management temperature range. Therefore, according to the constant-temperature conveying container according to this embodiment, especially when used in environments where the temperature is higher than the management temperature range of the temperature-maintaining item, the temperature maintenance time inside the container is further extended.

[0207] [Other variations of the connecting hole 18]

[0208] The structure of the connecting hole 18 in the constant temperature conveying container 10 is not limited to the structure described in embodiments 7 to 9 above. In embodiments 7 to 9 above, the connecting hole 18 is formed as a slit extending in the thickness direction in the middle track portion 14 and the upper track portion 15, respectively. However, in the embodiments of the present invention, the connecting hole 18 can be any structure that connects adjacent receiving portions S1 and S2 (or receiving portions S2 and S3) in the vertical direction. For example, the middle track portion 14 (or the upper track portion 15) can also be a mesh structure to connect adjacent receiving portions S1 and S2 (or receiving portions S2 and S3) in the vertical direction.

[0209] [Implementation Method 10]

[0210] The following describes Embodiment 10 of the present invention. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0211] The constant temperature conveying container involved in this embodiment differs from the structure of the side wall panel in embodiment 7. Specifically, the constant temperature conveying container involved in this embodiment differs from embodiment 7 in that (1) the uppermost receiving part among the multiple receiving parts arranged in the vertical direction is formed by a track part provided on the panel body instead of a top panel, and (2) the inner end of each track part is provided with protruding strips that protrude upward and downward.

[0212] The following is about Figure 9The shape of side wall panel 1 among the side wall panels 1 to 4 shown will be described. In the constant temperature conveying container according to this embodiment, the shape of side wall panels 2 to 4 is the same as that of side wall panel 1, so the description is omitted. Figure 14 This is a perspective view showing the outline of the internal structure of the side wall panel 1A of the constant temperature conveying container according to this embodiment.

[0213] The side wall panel 1A of the constant temperature conveying container involved in this embodiment is equipped with Figure 5 The fitted corner portion 7C shown serves as the structure of the aforementioned closed component. For example... Figure 14 As shown, the side wall panel 1A includes a panel body 11, a component 76 serving as a closure member, and a protective component 17. A support column 12, a lower track 13, a middle track 14A, a middle track 14B, an upper track 15, and an uppermost track 19 are provided on the inner surface of the panel body 11.

[0214] In the height direction, the lower track section 13, the middle track section 14A, the middle track section 14B, the upper track section 15, and the uppermost track section 19 are equally spaced from each other. The uppermost track section 19 is configured to be coplanar with the upper surface of the panel body 11.

[0215] Four receiving sections S1 to S4 are formed in the side wall panel 1A. Receiving section S1 has a space formed by the upper surface of the lower track section 13, the lower surface of the middle track section 14A, the side of the support section 12, the component 76, and the protective component 17, and this space is used to store material P. Receiving section S2 has a space formed by the upper surface of the middle track section 14A, the lower surface of the middle track section 14B, the side of the support section 12, the component 76, and the protective component 17, and this space is used to store material P. Receiving section S3 has a space formed by the upper surface of the middle track section 14B, the lower surface of the upper track section 15, the side of the support section 12, the component 76, and the protective component 17, and this space is used to store material P. Receiving section S4 has a space formed by the upper surface of the upper track section 15, the lower surface of the uppermost track section 19, the side of the support section 12, the component 76, and the protective component 17, and this space is used to store material P. For example, in the receiving section S4, the storage material P is inserted through the insertion port B4, and the storage material P slides on the upper track section 15 to move horizontally toward the support section 12, thereby the storage material P is received in the receiving section S4.

[0216] In addition, each of the housing sections S1 to S4 arranged in the vertical direction is provided with a connecting hole 18 that connects adjacent housing sections to each other.

[0217] In the constant-temperature conveying container of this embodiment, upward and downward protruding ribs are provided at the inner ends of each track section. Specifically, an upward protruding rib 13c is formed at the inner end of the lower track section 13. Additionally, an upward protruding rib 14c and a downward protruding rib 14d are formed at the inner ends of the middle track sections 14A and 14B, respectively. Furthermore, an upward protruding rib 15c and a downward protruding rib 15d are formed at the inner end of the upper track section 15. And, a downward protruding rib 19d is formed at the inner end of the uppermost track section 19. These ribs 13c, 14c, 14d, 15c, 15d, and 19d extend horizontally toward the sidewall panel 1A.

[0218] The protrusions 13c, 14c, 14d, 15c, 15d, and 19d function to lock the storage material P in place, preventing the storage material P housed in the housing sections S1 to S4 from falling inward. By providing these protrusions, the storage material P is stably held within the side wall panel 1A. Especially when the storage material P is relatively heavy, this reduces the load of the storage material P on the protective member 17, and allows the storage material P to be held stably.

[0219] Furthermore, in the constant-temperature conveying container according to this embodiment, the side wall panel 1A may or may not have a protective component 17. For example... Figure 14 As shown, when the side wall panel 1A has the protective component 17, the cold air from the storage material P (heat storage material) is less likely to flow into the storage chamber space, and the temperature fluctuations within the storage chamber space are stable. On the other hand, when the side wall panel 1A does not have the protective component 17, the cold air from the storage material P easily flows into the storage chamber space. Therefore, when the temperature regulation temperature of the storage material P is outside the management temperature range, after the storage material P is sealed to the side wall panel 1A, the temperature within the storage chamber space can be quickly adjusted to within the management temperature range.

[0220] Furthermore, in the constant-temperature conveying container according to this embodiment, component 76 is configured to fit into the side of the panel body 11. More specifically, component 76 has a fitting protrusion 76e. The fitting protrusion 76e is a raised strip extending in the height direction. Moreover, a fitting recess 1e is formed on the side of the panel body 11 opposite to the closing component 16A, which fits into the fitting protrusion 76e. This fitting recess 1e is a groove extending in the height direction. In addition, Figure 14 The component 77 shown fits into the side wall panel adjacent to the side wall panel 1A (equivalent to...). Figure 9The side of the side wall panel 2 shown. That is, in the constant temperature conveying container according to this embodiment, components 76 and 77 constitute the above-mentioned fitting corner portion 7C. The fitting corner portion 7C fits into the insertion corner portion between the side wall panel 1A and the side wall panel adjacent to the side wall panel 1A.

[0221] (Modified Example)

[0222] A modified example of the side wall panel of the constant temperature conveying container according to this embodiment will be described. Figure 15 It means Figure 14 The diagram shows a perspective view of the internal structure of a modified example of the side wall panel 1A, namely the side wall panel 1B.

[0223] like Figure 15 As shown, the sidewall panel 1B differs from the sidewall panel 1A in that it has slits (grooves) extending horizontally along the inner end of each track section. Specifically, a slit 13e is formed on the upper surface of the inner end of the lower track section 13. Additionally, slits 14e and 14f are formed on the upper and lower surfaces of the inner end of the middle track section 14A, respectively. The middle track section 14B also has slits 14e and 14f, similar to the middle track section 14A. Slits 15e and 15f are formed on the upper and lower surfaces of the inner end of the upper track section 15, respectively. Furthermore, a slit 19f is formed on the lower surface of the inner end of the uppermost track section 19.

[0224] Protective component 17A is inserted into these slits 13e, 14e, 15e, 14f, 15f, and 19f. For example, in the height direction, protective component 17A is inserted into slits 15e and 19f that are opposite each other. Thus, protective component 17A is fixed relative to the upper track portion 15 and the uppermost track portion 19. Therefore, the contained storage material P is fixed inside the storage portion S4 and will not fall towards the temperature holding component side.

[0225] [Objective of Embodiments 11-13 of the Invention]

[0226] Embodiments 11-13 of the present invention relate to the structure of heat storage material housed in the housing portion of the constant temperature transport container of Embodiments 1-10 described above, and more specifically to the connector of the heat storage material package. The connector of the heat storage material package according to Embodiments 11-13 includes at least two heat storage material packages connected to each other. Each heat storage material package includes heat storage material and an outer box made of a cuboid that houses the heat storage material. The at least two heat storage material packages are connected to each other on one side of the upper or lower surface of their respective outer boxes in a foldable structure.

[0227] Here, the connector described in Patent Document 6, because it is a structure in which heat-storing material is contained in a storage bag of a strip sheet, is difficult to stand upright on its own, leaving room for improvement in terms of sealing operability. In addition, the number of storage bags is predetermined, making it difficult to increase or decrease the amount of heat-storing material as needed.

[0228] Furthermore, the connector described in Patent Document 7 is a structure that directly connects high-rigidity cold storage plates via hinges, making it difficult to change the size of the plates. Typically, when temperature regulation of heat storage materials is required, it is difficult to use large-sized heat storage materials due to the limited size of the constant temperature bath and the refrigerator chamber.

[0229] Therefore, in the technology described in Patent Documents 6 and 7, there is room for improvement in the connection of the heat storage material encapsulation component.

[0230] In addition to the effects of embodiments 1 to 10 described above, embodiments 11 to 13 of the present invention also aim to achieve a connector for a heat storage material package with excellent workability in terms of temperature regulation and encapsulation.

[0231] [Implementation Method 11]

[0232] Figure 16 This is a perspective view showing the structure of the connector P3 of the heat storage material package according to this embodiment and the heat storage material T provided in the connector P3, showing the state in which the connector P3 is folded. Figure 17 It is a three-dimensional diagram showing the state of the connector P3 unfolded and bent. Figure 18 These are the side view, top view, and bottom view representing the state where the connector P3 is unfolded and flattened.

[0233] like Figures 16-18 As shown, the connector P3 in this embodiment has heat storage material encapsulation parts 1P to 3P that are interconnected. Figures 16-18 The connector P3 shown is a structure obtained by connecting three heat storage material encapsulation components 1P to 3P. However, in the connector P3 according to this embodiment, the number of heat storage material encapsulation components connected to each other is not limited to three, and can be appropriately set according to the structure of the connector P3.

[0234] Here, the connection direction of the heat storage material encapsulation components 1P to 3P is set as the front-back direction. Furthermore, in the connection direction of the connector P3, the side of heat storage material encapsulation component 1P is designated as the front side, and the side of heat storage material encapsulation component 3P is designated as the rear side. In this embodiment, the up-down direction and the left-right direction (also referred to as the side direction) are set based on the aforementioned front-back direction. Additionally, the upper and lower sides represent the state where the connector P3 is unfolded and flat. Figure 18 Based on the side view. That is, in this embodiment, the side view is used as a reference. Figure 18 In the side view, the upper and lower sides are defined as the upper and lower sides.

[0235] As for the structure of the heat storage material encapsulation components 1P to 3P, for example, each of the heat storage material encapsulation components 1P to 3P includes a heat storage material T and an outer casing 1AP to 3AP for housing the heat storage material T. The outer casing 1AP to 3AP are boxes made of cuboids of the same dimensions. The outer casing 1AP includes a drawer portion 1BP that constitutes the housing space for the heat storage material T and a box body. The box body has an opening C on the side. The drawer portion 1BP has an opening at the top. By inserting the drawer portion 1BP into the box body through the opening C on the side, the drawer portion 1BP is housed inside the box body. By pulling the drawer portion 1BP out from the box body to the side, the opening D at the top of the drawer portion 1BP is exposed. Then, the heat storage material T is housed in the drawer portion 1BP through this opening D. In addition, the outer casings 2AP and 3AP have the same structure as the outer casing 1AP, so their description is omitted.

[0236] Next, the connection between the three heat storage material encapsulation components 1P to 3P in connector P3 will be described in further detail. For example... Figures 16-18 As shown, outer casing 1AP has a front side 11P, a rear side 12P, a top surface 13P, and a bottom surface 14P. Similarly, outer casing 2AP has a front side 21P, a rear side 22P, a top surface 23P, and a bottom surface 24P. Likewise, outer casing 3AP has a front side 31P, a rear side 32P, a top surface 33P, and a bottom surface 34P.

[0237] In connector P3, the outer casing 1AP of thermal storage material package 1P and the outer casing 2AP of thermal storage material package 2P are connected via connector A and are foldable. Similarly, the outer casing 2AP of thermal storage material package 2P and the outer casing 3AP of thermal storage material package 3P are connected via connector B and are foldable. Thermal storage material packages 1P to 3P are detachable from each other.

[0238] In the connector P3, at least two heat storage material packages 1P and 2P, selected from heat storage material packages 1P to 3P, are connected by connector A such that their respective outer casings 1AP and 2AP have their rear side 12P and front side 21P in contact with each other. Similarly, heat storage material packages 2P and 3P are connected by connector B such that their respective outer casings 2AP and 3AP have their rear side 22P and front side 31P in contact with each other.

[0239] Furthermore, the heat storage material encapsulation components 1P and 2P connect one side 21bP, 21bP of the lower surfaces 14P and 24P of the rear side 12P and the front side 21P, respectively. Similarly, the heat storage material encapsulation components 2P and 3P connect one side 22aP, 22aP of the upper surfaces 23P and 33P of the rear side 22P and the front side 31P, respectively. In other words, the connecting part A of the outer casings 1AP and 2AP connects one side 21bP of the lower surface 14P of the rear side 1AP in the outer casing 1AP with one side 21bP of the lower surface 24P of the front side 21P in the outer casing 2AP, making it foldable. Similarly, the connecting part B of the outer casings 2AP and 3AP connects one side 22aP of the upper surface 23P of the rear side 22P in the outer casing 2AP with one side 22aP of the upper surface 33P of the front side 31P in the outer casing 3AP.

[0240] In connector P3, one side 21aP of the upper surface 13P of the rear side 12P of the outer casing 1AP is separate from the other side 21aP of the upper surface 23P of the front side 21P of the heat storage material encapsulation component 2P. Similarly, one side 22bP of the lower surface 24P of the rear side 22P of the outer casing 2AP is separate from the other side 22bP of the lower surface 24P of the front side 31P of the outer casing 3AP.

[0241] Therefore, the heat storage material encapsulation component 1P rotates relative to the heat storage material encapsulation component 2P around one side 21bP of its lower surface 24P. When the connector P3 is unfolded, the heat storage material encapsulation component 1P rotates downward relative to the heat storage material encapsulation component 2P from the position where its lower surface 14P and lower surface 24P are in contact. Moreover, the rotation of the heat storage material encapsulation component 1P is stopped by the contact between its rear side surface 12P and its front side surface 21P. That is, when the connector P3 is unfolded, the heat storage material encapsulation component 1P can rotate relative to the heat storage material encapsulation component 2P within an angle range of 0° to 180°. Therefore, in the unfolded state of the connector P3, since the rotation of the heat storage material encapsulation component 1P is stopped by the front side surface 21P, the heat storage material encapsulation component 1P cannot rotate upward relative to the heat storage material encapsulation component 2P. On the other hand, with the connector P3 folded, the heat storage material encapsulation 1P rotates relative to the heat storage material encapsulation 2P with one side 21bP of the lower surface 24P as the axis. Moreover, the heat storage material encapsulation 1P is stacked relative to the heat storage material encapsulation 2P so that the lower surface 14P and the lower surface 24P are in contact with each other.

[0242] Similarly, the heat storage material encapsulation component 3P rotates about one side 22aP of the upper surface 23P relative to the heat storage material encapsulation component 2P. When the connector P3 is unfolded, the heat storage material encapsulation component 3P rotates upward relative to the heat storage material encapsulation component 2P from the position where the upper surface 33P and the upper surface 23P are in contact. Moreover, the rotation of the heat storage material encapsulation component 3P is stopped by the contact between the front side 31P and the rear side 22P. That is, when the connector P3 is unfolded, the heat storage material encapsulation component 3P can rotate relative to the heat storage material encapsulation component 2P within an angle range of 0° to 180°. Therefore, in the unfolded state of the connector P3, since the rotation of the heat storage material encapsulation component 3P is stopped by the rear side 22P, the heat storage material encapsulation component 3P cannot rotate downward relative to the heat storage material encapsulation component 2P. On the other hand, with the connector P3 folded, the heat storage material package 3P rotates relative to the heat storage material package 2P with one side 22aP of the upper surface 23P as the axis. Moreover, the heat storage material package 3P is stacked relative to the heat storage material package 2P so that the upper surface 33P and the upper surface 23P are in contact with each other.

[0243] According to the connector P3 of this embodiment, when the heat storage material encapsulation components 1P to 3P are unfolded flat without bending, heat storage material encapsulation component 1P cannot rotate upwards relative to heat storage material encapsulation component 2P, and heat storage material encapsulation component 3P cannot rotate downwards relative to heat storage material encapsulation component 2P. Therefore, when the heat storage material encapsulation components 1P to 3P are unfolded without bending, the connector P3 can maintain a flat state. Therefore, even if the connector P3 is placed perpendicular to the ground in the back-to-back direction (even if it is placed with the front side 11P of the connector P3 in contact with the ground), the connector P3 can maintain its unfolded state and stand upright on its own. Furthermore, the heat storage material encapsulation components 1P to 3P are all cuboid boxes. Therefore, even if the connector P3 is placed with its side in contact with the ground, the connector P3 can maintain its unfolded state and stand upright on its own. Therefore, according to this embodiment, it is possible to realize the connector P3 of the heat storage material encapsulation parts 1P to 3P used in the heat preservation of temperature-maintaining articles, which is assumed to be in a flat unfolded state.

[0244] Furthermore, when temperature-regulating heat storage materials used in constant-temperature conveying containers, large-sized heat storage materials cannot be used due to the limited size of the constant-temperature bath or freezer. On the other hand, when using small-sized heat storage materials, each material needs to be temperature-regulated individually, which is time-consuming. Additionally, when using small-sized heat storage materials, sealing the temperature-regulated materials into the constant-temperature conveying container requires sealing each material individually, which also takes time.

[0245] In the connector P3 of this embodiment, three heat storage material packages 1P to 3P are connected, and the heat storage material package 2P has two connecting portions (connecting portions A and B) with the other heat storage material packages 1P and 3P. Furthermore, the connector P3 is configured such that connecting portion B of one heat storage material package 2P is located on one side 22aP of the upper surface 23P, while connecting portion A of the other is located on one side 21bP of the lower surface 24P. By forming this configuration, the connector P3 can be folded back and forth in a zigzag pattern to a smaller size. Therefore, the heat storage material T within the heat storage material packages 1P to 3P can be temperature-controlled in a constant temperature bath or freezer while the connector P3 is folded. Thus, the temperature of the heat storage material T within the heat storage material packages 1P to 3P can be controlled regardless of the size of the constant temperature bath or freezer. Furthermore, as a connector P3, multiple small heat storage materials T can be encapsulated in a constant-temperature conveying container, thus simplifying the encapsulation operation of the heat storage materials T into the constant-temperature conveying container. As a result, the time required for the encapsulation operation of the heat storage materials T can be shortened. Therefore, according to this embodiment, a connector P3 for heat storage material encapsulation components 1P to 3P with excellent workability in temperature regulation and encapsulation can be realized.

[0246] Furthermore, according to the connector P3 of this embodiment, the heat storage material encapsulation components 1P to 3P are detachable from each other. Therefore, the number of connectors for the heat storage material encapsulation components can be freely adjusted. Thus, according to this embodiment, the design freedom of the dimensions of the connector P3, which corresponds to the dimensions of the constant temperature conveying container, is increased.

[0247] Furthermore, in the connector P3 described in this embodiment, the heat storage material encapsulation components 1P to 3P are not limited to a mutually detachable structure, as long as they can be folded via the connecting portions A and B. For example, the heat storage material encapsulation components 1P to 3P may also be a structure in which one side 21bP and 22aP are foldable to each other via tape or the like.

[0248] Furthermore, in the connector P3 described in this embodiment, the heat storage material encapsulation components 1P to 3P are connected in the front-to-back direction. However, the connection direction of the heat storage material encapsulation components 1P to 3P is not limited to the front-to-back direction. The heat storage material encapsulation components 1P to 3P can also be connected to each other in any direction, including the front-to-back direction and the left-to-right direction.

[0249] (Connecting section)

[0250] The connecting parts A and B in connector P3 will be explained. Furthermore, since connecting part B is identical to connecting part A, its explanation is omitted. Figure 19 This is a perspective view illustrating an example of the connecting part A of the connector P3, showing the outer casings 1AP and 2AP that are separated from each other.

[0251] like Figure 19 As shown, the outer casing 2AP has a front side 21P (first side) that contacts other outer casings 1AP connected to the outer casing 2AP; and a rear side 22P (second side) opposite to the front side 21P. Similarly, the outer casing 1AP has a rear side 12P that contacts other outer casings 2AP connected to the outer casing 1AP.

[0252] Here, a connecting member 4P is provided on one side 21bP of the lower surface 24P side of the front side 21P of the outer casing 2AP. On the other hand, a connecting port 5P is provided on one side 22aP of the upper surface 23P side of the rear side 22P. The side 22aP where the connecting port 5P is provided corresponds to the side of the upper surface 23P side of the side of the upper surface 23P and the lower surface 24P side of the rear side 22P that is opposite to the side of the lower surface 24P side where the connecting member 4P is provided.

[0253] Additionally, a connecting opening 5P is formed on one side 12b of the lower surface 14P side of the rear side 12P of the outer casing 1AP. Although not shown in the attached drawings, a connecting member 4P is provided on one side of the upper surface 13P side of the front side 11P of the outer casing 1AP.

[0254] In addition, although not shown in the attached drawings, the outer casing 3AP of the heat storage material encapsulation component 3P is the same as the outer casing 2AP, with a connecting member 4P provided on one side of the upper surface 33P of the front side 31P and a connecting port 5P provided on one side of the lower surface 34P of the rear side 32P.

[0255] When outer casings 1AP to 3AP are mounted with connecting member 4P on the bottom, the connecting opening 5P is positioned on the top of all outer casings 1AP to 3AP. That is, when mounted with connecting member 4P on the bottom, outer casings 1AP to 3AP have the same shape. In the connecting body P3, the connecting member 4P of outer casings 1AP to 3AP is located in different positions on the top and bottom sides, and correspondingly, the connecting opening 5P is also located in different positions. In this structure, on the two contacting sides of outer casings 1AP to 3AP, the connecting member 4P and the connecting opening 5P are opposite each other.

[0256] The connecting part A includes the aforementioned connecting member 4P and connecting opening 5P. In the outer casing 2AP, the connecting member 4P is a sheet-like structure that is substantially coplanar with the lower surface 24P. Furthermore, the connecting member 4P has a structure where one side 21bP is bent on the lower surface 24P side of the front side 21P. Therefore, the connecting member 4P can rotate about one side 21bP as an axis. The connecting opening 5P is an opening through which the connecting member 4P can be inserted.

[0257] Here, the connection port 5P of outer casing 1AP is configured to lock the connection part 4P of another outer casing 2AP when it is inserted. Figure 19 In the structure shown, the connecting member 4P has a wide portion 41P that is wider in the left-right direction and a narrow portion 42P that is narrower in the left-right direction. The narrow portion 42P and the wide portion 41P are arranged sequentially from one side 21bP towards the front in the connecting member 4P. The width of the wide portion 41P in the left-right direction is smaller than the width of the outer casing 1AP in the left-right direction, but larger than the width of the connecting opening 5P in the left-right direction. On the other hand, the width of the narrow portion 42P in the left-right direction is smaller than the width of the connecting opening 5P in the left-right direction. Therefore, by inserting the connecting member 4P of the outer casing 2AP into the connecting opening 5P of the outer casing 1AP, the outer casing 1AP and the outer casing 2AP are connected in a foldable manner. Moreover, in this state, since the wide portion 41P is stopped by the connecting opening 5P, the connecting member 4P will not separate from the connecting opening 5P. That is, the connection port 5P of the outer casing 1AP is locked by the connection part 4P of the other outer casing 2AP when the connection part 4P of the other outer casing 2AP is inserted.

[0258] In addition, Figure 19 In the structure shown, the outer casing 2AP has a connecting member 4P and a connecting opening 5P respectively provided on the front side 21P and the rear side 22P. However, in the connector P3 according to this embodiment, it is sufficient to have a connecting member 4P and a connecting opening 5P constituting the connecting part A between the sides (rear side 12P and front side 21P) where the outer casings 1AP and 2AP are in contact with each other. For example, the outer casing 2AP may also have a structure in which the connecting opening 5P is provided on both the front side 21P and the rear side 22P. In this case, the connecting member 4P is provided on the rear side 12P of the outer casing 1AP.

[0259] Preferably, such as Figure 19 As shown, the preferred outer casings 1AP to 3AP all have connecting components 4P and connecting ports 5P respectively provided on the front and rear sides. This allows the outer casings 1AP to 3AP to have the same shape, simplifying the manufacturing of the heat storage material encapsulation components 1P to 3P.

[0260] Furthermore, the material of the outer boxes 1AP to 3AP is not particularly limited, but from the viewpoint of ease of manufacture, a bendable sheet material is preferred. Preferably, the outer boxes 1AP to 3AP are composed of at least one of thick paper, corrugated cardboard, plastic corrugated cardboard, and plastic sheet.

[0261] (Cooling (temperature control) method for connector P3)

[0262] The cooling (temperature control) of the connector P3 according to this embodiment is performed with the connector P3 folded. That is, the cooling method of the connector P3 according to this embodiment is performed in a state where the outer casings 1AP to 3AP of the heat storage material encapsulation components 1P to 3P are connected and the heat storage materials T inside the connected outer casings 1AP to 3AP do not come into contact with each other. For example, the connector P3 is cooled by placing it in a constant temperature bath or freezer while the heat storage material encapsulation components 1P to 3P are stacked by folding the connector P3. As a result, the heat storage materials T inside the heat storage material encapsulation components 1P to 3P can be cooled without being limited by the size of the constant temperature bath or freezer.

[0263] Furthermore, a space is created between the outer casings 1AP to 3AP and the heat storage material T housed within these outer casings. Therefore, even when the heat storage material encapsulation components 1P to 3P are stacked, the heat storage material T inside the outer casings 1AP to 3AP does not come into contact with each other. Thus, compared to the case where the heat storage material T is simply stacked in a manner where the heat storage material T comes into contact with each other, the cooling efficiency of the heat storage material T is better.

[0264] Furthermore, by cooling through the partially folded connector P3 (in the unfolded state of the connector P3), the cooling efficiency of the heat storage material T is further improved. For example, as... Figure 17 As shown, the outer casings 1AP to 3AP are deployed in a state where the upper or lower surfaces of adjacent outer casings are separated and do not contact each other. By cooling the connector P3 in this deployed state, the cooling efficiency of the heat storage material T is further improved.

[0265] In the connector P3 of this embodiment, it is preferable that the heat storage material T is capable of changing shape. Examples of such a heat storage material T include materials that seal liquid or gel-like heat storage or cold storage components within a film-made bag. In this way, the heat storage material T, whose shape can be changed, cannot stand upright on its own. By using the connector P3 of this embodiment with such a heat storage material T that cannot stand upright on its own, a temperature-maintaining article can be maintained at a constant temperature while keeping the heat storage material T upright.

[0266] [Implementation Method 12]

[0267] Other embodiments of the present invention will be described below. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0268] Figure 20 This is a perspective view illustrating the structure of the connecting portion of the connector involved in this embodiment, showing the mutually separated outer casings 1AP and 2AP. Figure 21This is a perspective view showing the outer casing 2AP with its front side panel 21P unfolded. (Example) Figure 20 and Figure 21 As shown, the structure of the connecting component 4AP and the connecting port 5BP of the connector involved in this embodiment is different from that in embodiment 1.

[0269] The connecting component 4AP includes an insertion tongue 43P formed on the front side 21P of the outer casing 2AP and an insertion tongue 44P formed on the rear side 12P of the outer casing 1AP. Additionally, the connecting port 5BP includes an opening 51P formed on the rear side 12P of the outer casing 1AP and an opening 52P formed on the front side 21P of the outer casing 2AP.

[0270] like Figure 21 As shown, the front side 21P portion of the outer casing 2AP is composed of an outer wing 21cP and an inner wing 21dP. The inner wing 21dP is bent inward, and then the outer wing 21cP is bent inward in a manner that overlaps with the inner wing 21dP, thereby forming the front side 21P portion of the outer casing 1AP.

[0271] Additionally, two slits 24aP extending in the front-rear direction are provided on one side of the lower surface 24P of the outer casing 2AP, on the front side 21P side. The insert tongue 43P is a portion that can be bent downward through the two slits 24aP. The insert tongue 43P protrudes from one side of the lower surface 24P, on the front side 21P side, in a flat, unbent state and coplanar with the lower surface 24P.

[0272] Furthermore, the outer wing 21cP forms the front side 21P. An opening 52P is formed in the portion of the outer wing 21cP corresponding to one side 21bP of the lower surface 24P. An insert tongue 43P is inserted into the opening 52P. Therefore, in the left-right direction, the insert tongue 43P and the opening 52P are positioned in an overlapping position. By inserting the insert tongue 43P into the opening 52P, the outer wing 21cP is secured and does not separate from the lower surface 24P.

[0273] Additionally, the insert tongue 44P extends protruding from one side of the lower surface 14P of the rear side 12P of the outer casing 1AP. The insert tongue 44P is a rectangular sheet with a width approximately the same as the width of the outer casing 1AP in the left-right direction. When the portion forming the front side 21P of the outer casing 2AP is formed by bending the outer wing 21cP and the inner wing 21dP, the insert tongue 44P is inserted between the outer wing 21cP and the lower surface 24P. Furthermore, the insert tongue 44P is also provided on one side 22aP of the upper surface 23P of the rear side 22P of the outer casing 2AP.

[0274] Additionally, opening 51P is the size into which the tongue 43P can be inserted. When the front side 21P and the rear side 12P are in contact with each other, opening 51P and opening 52P are interconnected.

[0275] Next, the connection method between outer casing 1AP and outer casing 2AP will be explained. First, the front side 21P of outer casing 2AP is formed by bending the outer wing 21cP and the inner wing 21dP. Next, the insert tongue 44P is inserted between the outer wing 21cP and the lower surface 24P with the openings 51P and 52P overlapping. Then, the insert tongue 43P is inserted into both openings 51P and 52P, thus connecting outer casing 1AP to one side 21bP of the lower surface 24P of the front side 21P of outer casing 2AP, making it foldable.

[0276] Even the connectors involved in this embodiment can be used to create a heat storage material encapsulation connector with excellent workability for temperature regulation and encapsulation.

[0277] [Implementation Method 13]

[0278] Another embodiment of the present invention will be described below. Furthermore, for ease of explanation, components having the same functions as those described in the above embodiments will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0279] Figure 22 This is a perspective view showing the structure of the connector P4 according to this embodiment, illustrating the state in which the connector is folded. Figure 22 As shown, the structure of the outer casing 1EP to 3EP of the connector P4 involved in this embodiment is different from that in embodiment 1.

[0280] The outer casings 1EP to 3EP are boxes composed of cuboids of the same dimensions. The outer casing 1EP has an opening F on its side. The heat storage material T is housed inside the main body of the outer casing 1EP through this opening F. Furthermore, the outer casing 1EP has a wing 1FP that closes the opening F. The wing 1FP has a rotating part 1GP that rotates around one side of its upper surface and a fin 1HP. The rotating part 1GP is approximately the same size as the opening F and is the part that closes the opening F. Additionally, the fin 1G is connected to the rotating part 1GP and can be bent at the edge of the rotating part 1GP.

[0281] Within the outer casing 1EP, the fin 1HP is inserted into the opening F to house it within the casing body. This closes the opening F with the wing 1FP. Furthermore, by pulling the fin 1HP laterally from the casing body of the outer casing 1EP from this position, the rotating part 1GP rotates, exposing the opening F. Since the outer casings 2EP and 3EP have the same structure as the outer casing 1EP, their description is omitted.

[0282] Even the connector P4 involved in this embodiment can be used as a connector for a heat storage material package with excellent workability, including temperature regulation and encapsulation.

[0283] Furthermore, the connector P4 described in this embodiment is not limited to a structure that only houses the heat storage material T in the openings F of the outer casing 1EP to 3EP. A container-shaped component can also be housed together with the heat storage material T in the openings F of the outer casing 1EP to 3EP. This container-shaped component is a structure capable of housing the heat storage material T and being housed within the casing body via the openings F of the outer casing 1E to 3EP; for example, [examples would be provided]. Figure 16 The drawer section shown is 1BP. Figure 23 The connector P5 shown is in Figure 22 The opening F shown contains a structure that houses the drawer portion 1BP.

[0285] The constant-temperature transport container that can be used with the connectors described in embodiments 11-13 is not particularly limited as long as it is a structure that can be used with the connector of the heat storage material encapsulation component standing upright on its own. For example, a constant-temperature transport container in which the flatly unfolded connector P3 is placed longitudinally (with the front-back direction of the connector P3 being vertical) can be cited. In addition, a constant-temperature transport container in which the flatly unfolded connector P3 is placed laterally (with the front-back direction of the connector P3 being horizontal) can also be applied. For example, such as Figure 24 As shown, the connector P3 according to Embodiment 11 can be applied to the constant temperature conveying container 10 according to Embodiment 1.

[0309] Example

[0310] [Example 1, Comparative Examples 1 and 2]

[0311] [Assembly of constant-temperature transport containers]

[0312] Made Figure 25 The side wall panels of Embodiment 1, Comparative Examples 1 and 2 are shown. The side wall panel of Embodiment 1 is a horizontally inserted structure, and... Figure 9 Similarly, in the structure shown, adjacent heat storage material receiving portions in the vertical direction have interconnecting holes. Furthermore, in a plurality of receiving portions arranged in the vertical direction, these interconnecting holes are arranged to overlap when viewed from the vertical direction. The sidewall panel of Comparative Example 1 is a laterally inserted structure, and adjacent heat storage material receiving portions in the vertical direction do not have interconnecting holes. The sidewall panel of Comparative Example 2 is a longitudinally inserted structure.

[0313] Furthermore, in Examples 1, 1, and 2, the bottom panel 5 and the top panel 6 used the same components.

[0314] In each of Examples 1, 1, and 2, a constant-temperature transport container was assembled using four side wall panels, a bottom panel, and a top panel. In each of the constant-temperature transport containers of Examples 1, 1, and 2, no heat storage material was contained in the bottom panel. The top panel contained nine sheets of heat storage material with a melting temperature of 5°C (grade: Patthermo F5 latent heat storage material, 550g), nine 10mm thick insulation sheets (expanded polystyrene board), and nine sheets of heat storage material with a melting temperature of 0°C (grade: Cold Ice 0HG, 1000g). Furthermore, each side wall panel contained nine sheets of heat storage material with a melting temperature of 5°C (grade: Patthermo F5 latent heat storage material, 550g), nine 10mm thick insulation sheets, and eight sheets of heat storage material with a melting temperature of 0°C (grade: Cold Ice 0HG, 750g). Compared to the side wall panels, each receiving section contains three sets of heat storage materials with a melting temperature of 5°C and one set of heat storage materials with a melting temperature of 0°C. Additionally, the set of heat storage materials housed in the center of the lowest receiving section can be replaced by an empty box of the same size, instead of the heat storage materials with a melting temperature of 0°C.

[0315] [Evaluation of temperature holding time]

[0316] For each of the constant-temperature transport containers of Example 1, Comparative Examples 1 and 2, the time for maintaining the temperature of the storage chamber space at 2 to 8°C in an environment with an external temperature of 30°C or -10°C was measured. More specifically, the temperature at two specific locations (the upper part of the central portion and the lower part of the corner portion) of the storage chamber of each of the constant-temperature transport containers of Example 1, Comparative Examples 1 and 2 was measured, and the temperature holding time of 2°C to 8°C was evaluated based on the time-dependent temperature change.

[0317] 〔result〕

[0318] The results of evaluating the temperature holding time of 2°C to 8°C for each of the constant temperature conveying containers of Example 1, Comparative Example 1 and 2 are shown in Table 1.

[0319] Table 1

[0320]

[0321] As shown in Table 1, the temperature holding time of 2°C to 8°C in an environment of -10°C is almost the same among the constant temperature transport containers of Example 1, Comparative Examples 1 and 2.

[0322] On the other hand, at a temperature of 30°C, significant differences were observed in the temperature holding time from 2°C to 8°C among the constant-temperature transport containers of Examples 1, 1, and 2. Firstly, a comparison between Comparative Example 1 and Comparative Example 2 revealed that, at a temperature of 30°C, the temperature holding time from 2°C to 8°C for the constant-temperature transport container with a transverse placement structure (Comparative Example 1) tended to be shorter than that for the constant-temperature transport container with a longitudinal placement structure (Comparative Example 2). Furthermore, despite this trend, it was surprising that the temperature holding time from 2°C to 8°C for the constant-temperature transport container of Example 1, which had a connecting hole in its transverse placement structure, was longer than that for the constant-temperature transport container with a longitudinal placement structure (Comparative Example 2).

[0323] [Examples 2 and 3, Comparative Examples 3 and 4, and Reference Examples 1 and 2]

[0324] [Structure of a constant-temperature transport container]

[0325] Figure 26 This illustrates the structure of the constant-temperature transport container used in Examples 2, 3, Comparative Examples 3, 4, and Reference Examples 1, 2. Figure 26 2601 is a perspective view showing the internal structure of a constant-temperature transport container. Additionally, Figure 26 2602 is a perspective view showing the structure of the side wall panel of the constant temperature conveying container used in Examples 2, 3 and Reference Example 1. Figure 26 2603 is a perspective view showing the structure of the side wall panel of the constant temperature transport container used in Comparative Examples 3 and 4 and Reference Example 2.

[0326] exist Figure 26 In the constant-temperature transport container shown in 2601, four layers of receiving sections are formed on each of the four side wall panels. Furthermore, each receiving section can accommodate four sheets of a heat storage material with a melting temperature of 5°C (grade: PATTHERMO F5 latent heat storage material) (hereinafter, sometimes referred to as the first connecting body) and four sheets of a heat storage material with a melting temperature of 0°C (grade: ice 0HG) (hereinafter, sometimes referred to as the second connecting body). Additionally, five rows of receiving sections are formed on the top panel, each capable of accommodating five sheets of a heat storage material with a melting temperature of 5°C and five sheets of a heat storage material with a melting temperature of 0°C. Figure 26In the constant-temperature conveying container shown in 2601, each side wall panel can accommodate 16 sheets of heat storage material with a melting temperature of 5°C and 16 sheets of heat storage material with a melting temperature of 0°C. Furthermore, the entire four side wall panels can accommodate 64 sheets of heat storage material with a melting temperature of 5°C and 64 sheets of heat storage material with a melting temperature of 0°C. Additionally, the top panel can accommodate 25 sheets of heat storage material with a melting temperature of 5°C and 25 sheets of heat storage material with a melting temperature of 0°C. Therefore, the constant-temperature conveying container can accommodate 89 sheets of heat storage material with a melting temperature of 5°C and 89 sheets of heat storage material with a melting temperature of 0°C. Furthermore, each of the heat storage materials with a melting temperature of 5°C and a melting temperature of 0°C has an outer casing for housing the main body of the heat storage material.

[0327] In addition, such as Figure 26 As shown in 2602, in the constant-temperature conveying container used in Examples 2, 3 and Reference Example 1, three connecting holes that communicate with each other are equally formed on the side wall panel. On the other hand, as Figure 26 As shown in 2603, in the constant temperature transport container used in Comparative Examples 3 and 4 and Reference Example 2, no communication holes connecting the receiving parts to each other are formed on the side wall panel.

[0328] [Evaluation of temperature holding time]

[0329] The time it took to maintain the temperature of the storage room at 2–8°C under the 7Dsummer program was measured. The 7Dsummer program, designed to simulate a summer environment, is a cycle of steps 1–4 performed sequentially for a total of 24 hours, repeated six times. Step 1: Maintain an environment at 22°C for 4 hours. Step 2: Maintain an environment at 35°C for 2 hours. Step 3: Maintain an environment at 30°C for 12 hours. Step 4: Maintain an environment at 35°C for 6 hours.

[0330] In addition, regarding the evaluation of temperature holding time, specifically, the temperature at six specific locations (upper, middle, and lower parts of the central section and upper, middle, and lower parts of the corners) of each constant-temperature transport container was measured, and the temperature holding time of 2°C to 8°C was evaluated based on the time-dependent changes in this temperature.

[0331] [Example 2]

[0332] exist Figure 26The top panel and side panel receiving portions of the constant-temperature transport containers shown in 2601 and 2602 overlap to house a first connector and a second connector. The first connector is mounted with its position inside the receiving portion and the second connector outside. Furthermore, to prevent the first and second connectors from falling into the inward storage chamber, thick paper is installed inside the receiving portion to assemble the constant-temperature transport container. The assembled constant-temperature transport container is then placed in its storage chamber until the temperature drops below 8°C. Then, under the 7Dsummer program environment, the time it takes to maintain the temperature of the storage chamber at 2–8°C is measured.

[0333] In this embodiment, one sheet of heat storage material with a melting temperature of 5°C weighs 550g. Therefore, the total weight of the heat storage material with a melting temperature of 5°C contained in the constant temperature conveying container is 550g × 89 sheets = 49.0kg.

[0334] On the other hand, regarding the heat storage material with a melting temperature of 0°C used in this embodiment, the weight of the heat storage material housed in the housing portion of the top panel is different from that housed in the housing portion of the side wall panel. One sheet of heat storage material with a melting temperature of 0°C, weighing 1000g, is housed in the housing portion of the top panel. One sheet of heat storage material with a melting temperature of 0°C, weighing 700g, is housed in the housing portion of the side wall panel. Therefore, the total weight of the heat storage material with a melting temperature of 0°C housed in the constant-temperature conveying container is 1000g × 25 sheets + 700g × 64 sheets = 69.8kg.

[0335] The weight ratio of the heat storage material with a melting temperature of 5℃ to the heat storage material with a melting temperature of 0℃ is 1:1.4. Furthermore, a 10mm thick expanded polystyrene board is sealed inside the outer casing of the heat storage material with a melting temperature of 5℃, sandwiched between the heat storage material with a melting temperature of 5℃ and the heat storage material with a melting temperature of 0℃.

[0336] [Example 3]

[0337] Except for using a heat storage material with a melting temperature of 5°C that is not enclosed with a 10mm thick expanded polystyrene board and changing the weight ratio of the heat storage material with a melting temperature of 5°C to the heat storage material with a melting temperature of 0°C, the time for which the temperature of the storage chamber space of the constant temperature conveying container was maintained at 2 to 8°C was determined by the same method as in Example 2.

[0338] In this embodiment, one sheet of heat storage material with a melting temperature of 5°C weighs 800g. Therefore, the total weight of the heat storage material with a melting temperature of 5°C contained in the constant temperature conveying container is 800g × 89 sheets = 71.2kg.

[0339] On the other hand, the heat storage material with a melting temperature of 0°C used in this embodiment has the same structure as in Example 1. Therefore, the total weight of the heat storage material with a melting temperature of 0°C contained in the constant temperature conveying container is 1000g × 25 sheets + 700g × 64 sheets = 69.8kg.

[0340] The weight ratio of heat storage material with a melting temperature of 5℃ to heat storage material with a melting temperature of 0℃ is 1:1.

[0341] [Comparative Example 3]

[0342] In addition to Figure 26 In addition to the overlapping housing portions of the top panel and side panel of the constant temperature conveying container shown in Examples 2601 and 2603, which house the first connector and the second connector, the time during which the temperature of the storage chamber space of the constant temperature conveying container was maintained at 2 to 8°C was measured using the same method as in Example 2.

[0343] [Comparative Example 4]

[0344] In addition to using heat storage material with a melting temperature of 5°C that is not encased in 10mm thick expanded polystyrene board, and... Figure 26 In addition to the overlapping housing portions of the top panel and side panel of the constant temperature conveying container shown in Examples 2601 and 2603, which house the first connector and the second connector, the time during which the temperature of the storage chamber space of the constant temperature conveying container was maintained at 2 to 8°C was measured using the same method as in Example 2.

[0345] [Reference Example 1]

[0346] Except for changing the weight ratio of the heat storage material with a melting temperature of 5°C to the heat storage material with a melting temperature of 0°C, the time during which the temperature of the storage chamber space of the constant temperature conveying container was maintained at 2 to 8°C was determined by the same method as in Example 2.

[0347] In this reference example, one sheet of heat storage material with a melting temperature of 5°C weighs 300g. Therefore, the total weight of the heat storage material with a melting temperature of 5°C contained in the constant temperature conveying container is 300g × 89 sheets = 26.7kg.

[0348] In this reference example, one sheet of heat storage material with a melting temperature of 0°C and a weight of 1000g is housed in the receiving section of the top panel and the side panel. Therefore, the total weight of the heat storage material with a melting temperature of 0°C housed in the constant temperature conveying container is 1000g × 89 sheets = 89.0kg.

[0349] The weight ratio of the heat storage material with a melting temperature of 5℃ to the heat storage material with a melting temperature of 0℃ is 1:3.3. Furthermore, a 10mm thick expanded polystyrene board is sealed inside the outer casing of the heat storage material with a melting temperature of 5℃, sandwiched between the heat storage material with a melting temperature of 5℃ and the heat storage material with a melting temperature of 0℃.

[0350] [Reference Example 2]

[0351] In addition to Figure 26 In addition to the overlapping housing portions of the top panel and side panel of the constant temperature transport containers shown in 2601 and 2603, which house the first connector and the second connector, the time during which the temperature of the storage chamber space of the constant temperature transport container was maintained at 2 to 8°C was measured using the same method as in Comparative Example 5.

[0352] 〔result〕

[0353] The results of evaluating the temperature holding time of 2℃ to 8℃ for Examples 2, 3, and Comparative Examples 3 to 6 are shown in Table 1.

[0354]

[0355] The evaluation of the temperature holding time from 2°C to 8°C shown in Table 2 assumes a summer environment. Under this condition, when the weight ratio of the heat storage material with a melting temperature of 5°C to the heat storage material with a melting temperature of 0°C is 1:1.4 or less, the temperature holding time from 2°C to 8°C for the constant-temperature conveying container with a side wall panel having a connecting hole (Examples 2 and 3) is longer than that for the constant-temperature conveying container with a side wall panel without a connecting hole (Comparative Examples 3 and 4). On the other hand, when the weight ratio of the heat storage material with a melting temperature of 5°C to the heat storage material with a melting temperature of 0°C exceeds 1:1.4, the temperature holding time from 2°C to 8°C for the constant-temperature conveying container with a side wall panel without a connecting hole (Reference Example 2) is longer than that for the constant-temperature conveying container with a side wall panel having a connecting hole (Reference Example 1). Therefore, it can be seen that in summer, regarding the weight ratio of heat storage material with a melting temperature of 5℃ to heat storage material with a melting temperature of 0℃, when the weight of heat storage material with a melting temperature of 5℃ is 1, and when the weight of heat storage material with a melting temperature of 0℃ is 1.4 or less, the temperature holding time of 2℃ to 8℃ becomes longer.

[0356] If the ratio of the heat storage material with a melting temperature of 5°C to the heat storage material with a melting temperature of 0°C is too high, it is considered that the cold air from the heat storage material with a melting temperature of 0°C is excessively supplied to the heat storage material with a melting temperature of 5°C through the connecting hole. Furthermore, it is considered that this results in excessive consumption of the latent heat of the heat storage material with a melting temperature of 0°C. Therefore, the temperature holding time of the constant temperature conveying container of Reference Example 2 from 2°C to 8°C is longer than that of the constant temperature conveying container of Reference Example 1.

[0357] On the other hand, it is believed that in the weight ratio of heat storage material with a melting temperature of 5°C to heat storage material with a melting temperature of 0°C, the higher the ratio of heat storage material with a melting temperature of 5°C, the more air convection is promoted through the connecting holes, and the cold air from the heat storage material with a melting temperature of 0°C can be transferred to the heat storage material with a melting temperature of 5°C without waste. Moreover, it is believed that this results in a longer temperature holding time of 2°C to 8°C for the constant temperature conveying containers of Examples 2 and 3 than for the constant temperature conveying containers of Comparative Examples 3 and 4.
