  The present invention relates to a transport container for transporting a stored transport target product while keeping the temperature constant for a predetermined time, and a transport system using the transport container.

  Vegetables, fruits and other fruits and vegetables, fresh foods such as meat and fish, and flowers must be transported while maintaining a certain temperature suitable for each item during distribution in order to maintain freshness or maintain quality. is there. In addition, ethical drugs and chemicals are required to be transported under stricter temperature control than in the food supply chain.

  Usually, in a supply chain in Japan, fresh foods are transported to stores and the like by a vehicle having a cold insulation function while being kept cold from the production area. In recent years, business development outside of Japan has increased, but when transporting in countries and regions where a cold chain equivalent to that in Japan has not been established, it depends on the performance of the transport container to maintain the proper temperature of the goods to be transported. There are times when it must be. Therefore, it is estimated that in the future, the demand for transport containers that can keep the internal temperature constant will increase.

  Patent Document 1 describes an example of a transport container (cold insulation box) that can maintain the internal temperature well.

JP, 2015-160620, A

  In a transport container that is configured by combining multiple heat insulation panels such as vacuum insulation materials, the connection between the heat insulation panels becomes a heat conduction path, and heat is transferred between the inside and outside of the transport container to insulate performance. Decreases, and there is a problem that the temperature inside the transport container cannot be kept constant for a long time.

  The cold insulation box body described in Patent Document 1 includes a top panel, a side panel, and a bottom panel made of a heat insulating panel including a vacuum heat insulating material, a joint between adjacent side panels, and each side panel and bottom panel. The junction between the two is protected by the flexible heat insulating material, and the internal temperature can be maintained well.

  However, depending on the item to be stored in the transport container, the time that the transport container should keep the internal temperature constant (for example, transport time), and the temperature difference between the inside and outside of the transport container, the transport container It is necessary to further reduce the amount of heat transferred between the inside and the outside of the machine. In other words, the amount of heat transfer between the inside and outside of the transport container is further reduced over a longer period of time, and the transport with further improved thermal insulation function that can keep the temperature of the stored transported object within a predetermined temperature range for a predetermined time. A container is desired.

  The constant temperature transport container according to the present invention (hereinafter also simply referred to as “transport container”) suppresses the movement of heat between the inside and the outside of the transport container at the connection portion where the heat insulating members are connected to each other. And the temperature of the stored transport object can be kept within a predetermined temperature range required for the transport object for a predetermined time required for transport of the transport object. For example, the constant temperature transport container according to the present invention is configured by combining a plurality of heat insulating members, and includes a heat conduction suppressing body including a heat storage material in the connecting portion in order to suppress heat transfer at the connecting portion of the heat insulating member. The temperature of the stored transport object is kept within a predetermined temperature range for a predetermined time.

  In addition, since the transport container according to the present invention can optimize the amount and position of the heat storage material disposed inside the transport container, the weight of the transport container can be reduced, and the internal volume for storing the object to be transported can be reduced. It can be enlarged, and the transporter can efficiently transport the goods to be transported. Furthermore, the transport container according to the present invention has a feature that it is convenient to store when not in use, such as having a simple configuration and being able to be stored in a narrow place when not in use.

  In general, a transport container includes a heat insulating member and a heat storage material, and the size (volume) and number of the heat insulation member and the heat storage material are determined so that the product to be transported can be kept within a predetermined temperature range for a predetermined time. It is done. For this reason, the transport container may increase in weight even if it does not contain a product to be transported, and it may not be easy to move the transport container. Therefore, it is desirable that the transport container has a smaller weight.

  Hereinafter, a constant temperature transport container according to an embodiment of the present invention will be described with reference to the drawings.

  4 is a plan view of the transport container 1 (that is, the storage unit 12) with the lid 11 removed, as viewed from the direction of the arrow D shown in FIG.

  5A to 5C are plan views of the lid portion 11 as seen from the direction of the arrow C shown in FIG. 6 (the direction of the arrow C shown in FIG. 7 described later).

  2, 3 and 6 show the transport container 1 with the lid 11 closed.

  As shown in FIGS. 1A and 1B, the storage portion 12 of the transport container 1 includes a plurality of heat insulating members 2 and is configured by combining these heat insulating members 2. As shown in FIGS. 2 to 4, the heat insulating member 2 of the storage unit 12 includes one front heat insulating member 2 a, two side heat insulating members 2 b, one back heat insulating member 2 c, and one bottom heat insulating member 2 e. The front heat insulating member 2a faces the back heat insulating member 2c and contacts the two side heat insulating members 2b. The two side heat insulating members 2b are opposed to each other and are in contact with the front heat insulating member 2a and the back heat insulating member 2c. The bottom heat insulating member 2e is in contact with the front heat insulating member 2a, the side heat insulating member 2b, and the back heat insulating member 2c, and faces the lid portion 11 when the lid portion 11 is closed. The front heat insulating member 2a, the side heat insulating member 2b, and the back heat insulating member 2c are erected on the bottom heat insulating member 2e.

  Inside the storage part 12, a storage space 14 is configured by these heat insulating members 2 (the front heat insulating member 2a, the side heat insulating member 2b, the back heat insulating member 2c, and the bottom heat insulating member 2e). In the storage space 14, the product 7 to be transported is stored.

  As shown in FIGS. 2, 3, and 5 </ b> A to 5 </ b> C, the lid portion 11 of the transport container 1 includes an upper surface heat insulating member 2 d that is the heat insulating member 2. When the lid portion 11 is closed, the upper surface heat insulating member 2d is in contact with the front heat insulating member 2a, the side heat insulating member 2b, and the rear heat insulating member 2c.

  The outer periphery of the heat insulating member 2 (front heat insulating member 2a, side heat insulating member 2b, back heat insulating member 2c, top heat insulating member 2d, and bottom heat insulating member 2e) is covered with a cover 13 (FIGS. 1A to 4). An existing heat insulating cover or heat insulating sheet can be used for the cover 13.

  In the transport container 1, a portion where the heat insulating members 2 are connected to each other is referred to as a connecting portion 3 (FIGS. 1A to 4). The two heat insulating members 2 form, for example, the connecting portion 3 by connecting the end surfaces of one heat insulating member 2 and the surface of the other heat insulating member 2 in contact with each other.

  In order to keep the temperature inside the transport container 1 constant, it is necessary to make the inside of the transport container 1 less susceptible to the temperature outside the transport container 1. For this reason, the heat insulating member 2 is made of a heat insulating material having high heat insulating performance, such as a closed cell heat insulating material or a vacuum heat insulating material. These heat insulating materials have excellent heat insulating performance against heat passing through the heat insulating material in the thickness direction, but heat is transferred through the surface of the heat insulating material through one end surface of the heat insulating material. From the surface to the other surface opposite to the surface, that is, a phenomenon in which heat is conducted through the end face of the heat insulating material as a path.

  Therefore, in the transport container 1 configured by combining a plurality of heat insulating members 2, the connection portion 3 where the heat insulating members 2 are connected to each other serves as a heat conduction path, and heat transfer is performed between the inside and the outside of the transport container 1. Occur. If the temperature difference between the inside and the outside of the transport container 1 is large, the heat conduction at the connecting portion 3 becomes remarkable, and even if a heat storage material is arranged inside the transport container 1, the temperature of the transport object 7 and the storage space 14 is increased. Is difficult to keep within a predetermined temperature range for a predetermined time.

  Therefore, the transport container 1 according to the present embodiment includes the heat conduction suppressing body 4 in the connection portion 3 in order to reduce the amount of heat transfer in the connection portion 3, and sets the temperature of the transport object 7 and the storage space 14 to a predetermined value. Within the temperature range for a predetermined time.

  As shown in FIGS. 1A, 1B, and 4, the heat conduction suppressing body 4 includes a heat conduction suppressing body (vertical direction) 4a erected on the bottom heat insulating member 2e. The heat conduction suppressing body (vertical direction) 4a is installed in the connecting portion 3 between the front heat insulating member 2a and the side heat insulating member 2b and the connecting portion 3 between the side heat insulating member 2b and the back heat insulating member 2c.

  Furthermore, as shown in FIGS. 2 to 4, the heat conduction suppressing body 4 includes a heat conduction suppressing body (horizontal direction) 4 b provided in parallel to the bottom heat insulating member 2 e. The heat conduction suppressing body (horizontal direction) 4b includes a connecting portion 3 between the bottom heat insulating member 2e and the front heat insulating member 2a, a connecting portion 3 between the bottom heat insulating member 2e and the side heat insulating member 2b, a bottom heat insulating member 2e and the back surface. It installs in the connection part 3 with the heat insulation member 2c.

  Furthermore, as shown in FIG. 2, the heat conduction suppressing body 4 includes a heat conduction suppressing body (horizontal direction) 4b provided in parallel with the upper surface heat insulating member 2d. The heat conduction suppressing body (horizontal direction) 4b includes a connecting portion 3 between the upper surface heat insulating member 2d and the front heat insulating member 2a, a connecting portion 3 between the upper surface heat insulating member 2d and the side heat insulating member 2b, an upper surface heat insulating member 2d, and the rear surface. It installs in the connection part 3 with the heat insulation member 2c.

  In FIGS. 1A to 4, all the heat insulating members 2 (front heat insulating member 2 a, side heat insulating member 2 b, back heat insulating member 2 c, top heat insulating member 2 d, and bottom heat insulating member 2 e) and The heat conduction suppressing body 4 (the heat conduction suppressing body (vertical direction) 4a and the heat conduction suppressing body (horizontal direction) 4b) is not shown.

  The heat conduction suppressing body 4 (the heat conduction suppressing body (vertical direction) 4a and the heat conduction suppressing body (horizontal direction) 4b) is insulative so as to be in contact with the heat insulating member 2 constituting the connecting portion 3 and to cover at least the connecting portion 3. Provided on member 2. The heat conduction suppressing body 4 may be provided on the heat insulating member 2 so as to cover only the connecting portion 3. The heat conduction suppressing body 4 extends in the longitudinal direction along the connecting portion 3.

  If a heat insulating material is installed so as to cover the connection part 3, the movement of heat between the inside and the outside of the transport container 1 can be suppressed. For example, when the plant is the product to be transported 7, transport Since the target product 7 itself generates heat, it is difficult to keep the temperature inside the transport container 1 constant.

  Therefore, in the transport container 1 according to the present embodiment, as shown in FIGS. 1A to 3, the heat conduction suppressing body 4 (4 a, 4 b) includes the heat storage material 6 b. The heat storage material 6 b extends in the longitudinal direction along the connection portion 3. Any heat storage material 6b may be used as long as it has a heat retention function for keeping the temperature constant and has a heat storage temperature (heat retention temperature) required for the product 7 to be transported. Since the heat conduction suppressing body 4 includes the heat storage material 6b, and the amount of heat stored in the heat storage material 6b suppresses heat conduction in the connection portion 3, the transport container 1 according to the present embodiment Heat transfer between the two can be suppressed.

  Since the transport container 1 according to the present embodiment has such a configuration, the temperatures of the transport object 7 and the storage space 14 can be maintained within a predetermined temperature range for a predetermined time.

  In the transport container 1 according to the present embodiment, as shown in FIGS. 1B to 3, the heat conduction suppressing body 4 can include a heat storage material 6 b and a heat conduction plate 5. The heat conductive plate 5 is a plate-like member having heat conductivity, and extends in the longitudinal direction along the connection portion 3. The heat conduction plate 5 is preferably made of a metal having good heat conduction, and is preferably made of, for example, copper. The heat conductive plate 5 is provided on the heat insulating member 2 so as to contact the heat insulating member 2 constituting the connecting portion 3 and cover at least the connecting portion 3. The heat conductive plate 5 may be provided on the heat insulating member 2 so as to cover only the connecting portion 3. The heat storage material 6 b is provided on the heat conductive plate 5 so as to be in contact with the heat conductive plate 5.

  The heat conductive plate 5 has an effect of uniformly spreading the heat transmitted to the heat conductive plate 5 and the heat amount of the heat storage material 6b. The heat storage material 6b provided on the heat conduction plate 5 is a connection that is a heat conduction path by conducting the heat amount of the heat storage material 6b to the heat conduction plate 5 or conducting the heat transmitted to the heat conduction plate 5. The movement of heat in the part 3 is suppressed.

  In the storage space 14, the transport container 1 is provided with the heat conductive plate 5 so as to be in contact with the heat insulating member 2, and inside the heat conductive plate 5 (closer to the center of the storage space 14 than the heat conductive plate 5). The heat storage material 6b is disposed in contact with the heat conductive plate 5. Since the heat conductive plate 5 is disposed outside the heat storage material 6 b (a position farther from the center of the storage space 14 than the heat storage material 6 b) and covers the connection portion 3, the heat conduction plate 5 is a transport container 1 that passes through the connection portion 3. Block heat transfer from outside to inside. The heat transmitted to the heat conductive plate 5 is transmitted to the heat storage material 6b, and conduction to the storage space 14 and the product to be transported 7 is suppressed. In the transport container 1 according to the present embodiment, since the heat conduction plate 5 is disposed outside the heat storage material 6b in the storage space 14, the movement of heat from the outside to the inside of the transport container 1 can be effectively blocked. The movement of heat from the inside of the transport container 1 to the outside can be blocked mainly by the heat storage material 6b.

  By providing the heat conductive plate 5, the transport container 1 according to the present embodiment further improves the effect of maintaining the temperatures of the transport object 7 and the storage space 14 within a predetermined temperature range for a predetermined time.

  Since the heat conducting plate 5 is provided on the heat insulating member 2 so as to cover at least the connection portion 3, it is preferably an L-shaped member in which two planes are connected to each other at an angle of approximately 90 degrees. That is, the heat conductive plate 5 is preferably an L-shaped member in a cross section perpendicular to the longitudinal direction along the connecting portion 3. The length of the heat conducting plate 5 in the longitudinal direction is preferably equal to the length of the connecting portion 3. The width of the two planes constituting the heat conducting plate 5 (the length of the two sides of the L-shape) is set so that the end surface of the heat insulating member 2 serves as a path from one surface of the heat insulating member 2 to the other side opposite to this surface. It is desirable for the length to cover a region where the change in the surface temperature of the heat insulating member 2 generated by the heat conducted to the surface is remarkable.

  In addition, although the heat conduction suppression body 4 showed the transport container 1 provided with the thermal storage material 6b and the heat conductive board 5 in FIG. 1B-FIG. 3, the heat conduction suppression body 4 is a heat conduction board as shown to FIG. 1A. 5 may be provided, and only the heat storage material 6b may be provided. In the configuration in which the heat conduction suppressing body 4 includes only the heat storage material 6 b, the heat storage material 6 b is provided on the heat insulating member 2 so as to contact the heat insulating member 2 configuring the connection portion 3 and cover at least the connection portion 3. You may provide the thermal storage material 6b in the heat insulation member 2 so that only the connection part 3 may be covered.

  In the transport container 1 shown in FIGS. 1A and 1B, the heat storage material 6 b included in the heat conduction suppression body (vertical direction) 4 a has a triangular shape in a cross section perpendicular to the longitudinal direction along the connection portion 3. In the transport container 1 shown in FIGS. 2 and 3, the heat storage material 6 b provided in the heat conduction suppressing body (horizontal direction) 4 b provided in parallel to the bottom heat insulating member 2 e is perpendicular to the longitudinal direction along the connecting portion 3. The cross-sectional shape is a triangle. When the heat storage material 6b has such a shape, the volume of the storage space 14 can be increased.

  Furthermore, the transport container 1 according to the present embodiment can include a heat storage material 6a in addition to the heat storage material 6b (FIGS. 1A to 4). The heat storage material 6a is a storage space other than the position covering the connection portion 3 on the surface of the heat insulating member 2 (front heat insulating member 2a, side heat insulating member 2b, back heat insulating member 2c, top heat insulating member 2d, and bottom heat insulating member 2e). 14 can be arranged at a position facing 14. Any heat storage material 6a may be used as long as it has a heat retaining function for keeping the temperature constant and has a heat storage temperature (heat retaining temperature) required for the product 7 to be transported. As long as the heat storage material 6 a is inside the transport container 1, the heat storage material 6 a can be arranged at any position according to the transport container 1 and the transport object 7. The optimum position of the heat storage material 6a is determined so that the temperature of the product to be transported 7 can be kept within a predetermined temperature range for a predetermined time.

  In order for the heat conduction suppression body 4 provided with the heat storage material 6b to suppress the movement of heat at the connection portion 3, the heat storage material 6a disposed inside the transport container 1 is used to store the amount of heat (heat storage amount) in the transport container 1. Can be effectively used to keep the temperature inside the container (that is, the temperature of the goods 7 to be transported and the storage space 14) constant. Therefore, the transport container 1 provided with the heat storage material 6a can more effectively maintain the temperatures of the transport object 7 and the storage space 14 within a predetermined temperature range for a predetermined time.

  The heat storage material 6a and the heat storage material 6b may be either a sensible heat storage material or a latent heat storage material. The shape of the heat storage materials 6 a and 6 b may be arbitrary, such as a block shape or a sheet shape, as long as it can be arranged inside the transport container 1.

  In addition, although the transport container 1 provided with the heat storage material 6a was shown in FIG. 1A-FIG. 4, the transport container 1 does not need to be provided with the heat storage material 6a.

  Moreover, as shown in FIG. 3, the upper surface heat insulating member 2d can include a heat storage material 6b that also serves as the heat storage material 6a shown in FIG. The heat storage material 6b provided on the upper surface heat insulating member 2d shown in FIG. 3 covers the plurality of connection portions 3 and connects these connection portions 3 to the surface of the upper surface heat insulating member 2d facing the storage space 14. It is extended and arranged. Moreover, as shown in FIG. 3, the heat conductive plate 5 which contacts such a heat storage material 6b can be provided in the upper surface heat insulating member 2d. The amount of heat stored in the heat storage material 6b provided on the upper surface heat insulating member 2d is such that the temperature between the transport object 7 and the storage space 14 is kept constant, and the heat between the inside and the outside of the connection portion 3 is constant. Used for both movement control.

  5A to 5C are plan views of the lid portion 11 as seen from the direction of the arrow C shown in FIG. 6, and the heat conduction suppressing body 4 (the heat storage material 6 b and the heat conduction plate 5 provided on the upper surface heat insulating member 2 d. ). The upper surface heat insulating member 2 d shown in FIGS. 5A to 5C includes a heat storage material 6 b and an annular heat conductive plate 5 as the heat conduction suppressing body 4. The upper surface heat insulating member 2d shown in FIG. 5C further includes a heat storage material 6a. In addition, the heat conduction suppression body 4 provided in the upper surface heat insulating member 2d may not include the heat conductive plate 5 but may include only the heat storage material 6b.

  The upper surface heat insulating member 2d shown in FIG. 5A includes three heat storage materials 6b. One of the heat storage materials 6b covers the connecting portion 3 between the upper surface heat insulating member 2d and the front heat insulating member 2a, covers the connecting portion 3 between one of the upper surface heat insulating member 2d and the side heat insulating member 2b, and covers the upper surface heat insulating member 2d and the rear surface. It installs so that the connection part 3 with the heat insulation member 2c may be covered. The other of the heat storage material 6b covers the connecting portion 3 between the upper surface heat insulating member 2d and the front heat insulating member 2a, covers the connecting portion 3 between the upper surface heat insulating member 2d and the other side heat insulating member 2b, and the upper surface heat insulating member 2d. It installs so that the connection part 3 with the back heat insulation member 2c may be covered. The remaining one of the heat storage materials 6b covers the connecting portion 3 between the upper surface heat insulating member 2d and the front heat insulating member 2a, and covers the other two portions so as to cover the connecting portion 3 between the upper surface heat insulating member 2d and the rear heat insulating member 2c. It is installed between the heat storage materials 6b.

  The heat storage amount of the heat storage material 6b shown in FIG. 5A is used for both keeping the temperature of the product to be transported 7 and the storage space 14 constant and suppressing the movement of heat between the inside and the outside at the connection portion 3. Used.

  The top heat insulating member 2d shown in FIG. 5B includes four heat storage materials 6b. Of the four heat storage materials 6b, one covers the connecting portion 3 between the upper surface heat insulating member 2d and the front heat insulating member 2a, the other two cover the connecting portion 3 between the upper surface heat insulating member 2d and the side heat insulating member 2b, and the remaining 1 One is installed so that the connection part 3 of 2 d of upper surface heat insulation members and the back heat insulation member 2c may be covered.

  The heat storage amount of the heat storage material 6b shown in FIG. 5B is mainly used for suppressing heat transfer between the inside and the outside at the connection portion 3.

  The upper surface heat insulating member 2d shown in FIG. 5C includes four heat storage materials 6b and one heat storage material 6a. Of the four heat storage materials 6b, one covers the connecting portion 3 between the upper surface heat insulating member 2d and the front heat insulating member 2a, the other two cover the connecting portion 3 between the upper surface heat insulating member 2d and the side heat insulating member 2b, and the remaining 1 One is installed so that the connection part 3 of 2 d of upper surface heat insulation members and the back heat insulation member 2c may be covered. The heat storage material 6a is installed in a region (center portion of the lid portion 11) surrounded by the four heat storage materials 6b.

  The heat storage amount of the heat storage material 6b shown in FIG. 5C is mainly used for suppressing heat transfer between the inside and the outside at the connection portion 3. The heat storage amount of the heat storage material 6a shown in FIG. 5C is used to keep the temperatures of the transport object 7 and the storage space 14 constant.

  In the transport container 1 according to the present embodiment, the heat storage material 6b and the heat storage material 6a in the upper surface heat insulating member 2d can be arranged at various positions as in the examples shown in FIGS. 5A to 5C. The optimum positions of the heat storage material 6b and the heat storage material 6a in the upper surface heat insulating member 2d are determined so that the temperature of the transport object 7 can be kept within a predetermined temperature range for a predetermined time.

  As described above, the heat storage material 6b is mainly used to suppress the movement of heat at the connection portion 3, and the heat storage material 6a is used to keep the temperature inside the transport container 1 constant. For this reason, the thermal storage material 6b and the thermal storage material 6a can use the thermal storage material from which thermal storage temperature (thermal insulation temperature) differs mutually. The heat storage temperature and amount (volume) of the heat storage material 6b and the heat storage material 6a, and the position of the heat storage material 6a are, for example, the heat retention temperature required for the product to be transported 7, the size of the transport container 1 (volume of the storage space 14), And the temperature outside the transport container 1 can be determined.

  The transport container 1 according to the present embodiment can optimize the amount and position of the heat storage material 6b and the heat storage material 6a so that the temperature of the product to be transported 7 can be maintained within a predetermined temperature range for a predetermined time. . For this reason, it can prevent that the goods 7 and the storage space 14 deviate from the temperature which should be maintained because the quantity of the heat storage materials 6a and 6b is inappropriate, the weight of the transport container 1 is reduced, and the transport The internal volume of the container 1 can be increased. Note that the optimum heat storage temperature, amount, position, and the like of the heat storage materials 6a and 6b can be obtained by numerical simulation, for example.

  It is preferable that the transport container 1 can be stored in a small place when not in use. For this reason, the transport container 1 may have a configuration that can be folded or disassembled. In the transport container 1 according to the present embodiment, if the heat conducting plate 5 is made of metal, the heat conducting plate 5 serves as a reinforcing member that supports the transport container 1 from the inside when the foldable or disassembleable transport container 1 is used. Has an effect.
