  The conventional transport container for medical devices can easily hold the product to be transported within a predetermined temperature range. However, since the heat transfer in the transport container is suppressed, the non-uniformity of the temperature distribution in the transport container may become serious. For example, if the amount of heat released from the bottom surface of the transport container is too large, the temperature on the bottom surface side decreases, and the temperature of the heat storage material on the bottom surface side decreases early. In this case, even if a heat storage material having a sufficient heat storage amount is arranged on the upper surface side in consideration of heat dissipation from the bottom surface side, it becomes difficult to transfer the heat storage amount to the heat radiating part by the heat insulation function, and the amount of heat Cannot be used effectively. The temperature of the product to be transported decreases from the bottom side.

  When transporting a plurality of products to be transported, it is difficult to transfer heat between the products to be transported. As a result, a transported product that cannot be maintained within a desired temperature range may occur. In addition, when the outside air temperature is low or when the transportation time is long, the amount of heat release increases, so it is necessary to add heat storage to supplement heat dissipation. It may not be possible.

  The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to maintain a predetermined temperature range for a long time in a constant temperature transport container having a simple configuration.

  In this constant temperature transport container, the upper end portion of the heat conducting member may be formed in a bent shape, and the bent shape portion may be used to allow the user to take out the individual packaging container. You may cover with 2 heat conductive members. Further, the inner surface shape of the heat insulating container is a cylindrical shape, and the heat insulating material is a mat-like vacuum heat insulating material, and a plurality of vacuum heat insulating materials are laminated along the cylindrical surface, and the circumferential end portion of the vacuum heat insulating material May be changed in the stacking direction, and the lower end surface of the vacuum heat insulating material may be lower than the inner bottom surface of the heat insulating container. A temperature sensor may be provided on the back surface of the lid, and a display unit for displaying the temperature detected by the temperature sensor may be provided on the surface of the lid, and the temperature sensor may be in contact with the heat conducting member.

In order to achieve the above object, a thermostatic transport container includes a heat insulating container and a lid that allows the heat insulating container to be sealed, and the heat insulating container includes a heat insulating member disposed on an inner peripheral surface side, and the heat insulating member is formed. The heat conduction member is disposed in the space inside the heat insulating container, and the heat conduction member can accommodate the heat insulation member that accommodates the transported goods and the heat storage material that changes in phase with solid and liquid alternately stacked. , it is disposed so as to contact these heat storage material, and to be transmitted through the heat conducting member thermally one of the heat storage material to another heat storage material of the laminated heat storage material.

In order to achieve the above object, a thermostatic transport container includes a heat insulating container and a lid that allows the heat insulating container to be sealed, and the heat insulating container includes a heat insulating member disposed on an inner peripheral surface side, and the heat insulating member is formed. A heat conduction member is disposed in the inner space of the heat insulating container, and a plurality of heat storage materials that change phase between solid and liquid enclosed in the container are disposed on the inner surface side of the heat conduction member.

FIG. 2 is a partial cross-sectional perspective view of an individual container stored in the constant temperature transport container shown in FIG. 1.

The longitudinal cross-sectional view of the other Example of the constant temperature transport container which concerns on this invention. The longitudinal cross-sectional view of the further another Example of the constant temperature transport container which concerns on this invention.

  Hereinafter, an embodiment of the constant temperature transport container according to the present invention will be described with reference to FIGS. FIG. 1 is a longitudinal sectional view of the constant temperature transport container 30, FIG. 2 is a detailed perspective view of the individual container 8 accommodated in the constant temperature transport container 30, and FIG. 3 is a cross sectional view of the constant temperature transport container 30. The constant temperature transport container 30 includes a cylindrical heat insulating container 1 and a lid 15 that covers the upper surface of the heat insulating container 1.

  The heat insulating container 1 is formed of a heat insulating material container 2 having a cylindrical outer shape, and the vacuum heat insulating material 3 is double disposed along the inner wall of the container 2. Inside the vacuum heat insulating material 3, a metal heat conduction member 4 having a good heat conductivity in the shape of a bent plate is arranged extending in the vertical direction. The lower end portion of the heat conducting member 4 is positioned slightly above the vacuum heat insulating material 3 and forms a bottom surface portion 4a. On the inner surface of the lid 15, a heat conducting member 4b is stuck. A temperature sensor 20 that detects the temperature of the heat conducting member 4 in contact with the heat conducting member 4 is attached to a part of the lid 15. A temperature indicator 21 for displaying the temperature detected by the temperature sensor 20 is provided on the upper surface of the lid 15.

  As shown in FIG. 3, the heat conducting member 4 has a shape in which two opposing plates are connected at the lower end. A space formed between the two plates of the heat conducting member 4 is a space for storing a plurality of individual containers 8, three in FIG. Urethane is filled in the space between the vacuum heat insulating material 3 and the outside of the space for housing the individual container 8, and the heat conducting member 4 is held together with the heat insulating action. The individual container 8 has a rectangular parallelepiped shape with rounded corners, and has a size matching the space formed by the heat conducting member 4. Since the size of the individual container 8 is adjusted to the heat conducting member 4, the individual container 8 is prevented from being displaced in the constant temperature transport container 30 during transportation. A rectangular parallelepiped transport article 6 covered with the second heat conducting member 7 is held inside the individual container 8, and the gap between the second heat conducting member 7 and the individual container 8 is held in the individual container 8. Is filled with the heat storage material 5.

  Here, the vacuum heat insulating material 3 is formed by sealing the periphery of a fibrous core member for maintaining the shape with a thin plate or a film and evacuating the inside, and examples of the core member include metal fine wires and glass wool fibers. As the film material, a thin plate or film of aluminum or stainless steel is used. The heat conducting member 4 is, for example, a copper plate, and the individual container 8 is made of a transparent resin so that the internal state can be grasped. Since the vacuum heat insulating material 3 is formed in a mat shape and is wound around the inner periphery of the heat insulating container 1, a slight gap is formed at the circumferential end of the vacuum heat insulating material 3. Therefore, another vacuum heat insulating material 3 is further wound inside so as to cover this end. In this case, the circumferential end position of the inner vacuum heat insulating material 3 is made different from the circumferential end position of the outer vacuum heat insulating material 3.

  FIG. 2 shows details of holding the transported product 6 in the individual container 8. The individual container 8 has a lid portion 10 and a box portion 11 having substantially the same shape. A plurality of upper ribs 12 are formed inside the top plate portion 10 a of the lid portion 10, and a plurality of lower ribs 13 are formed inside the bottom plate portion 11 a of the box portion 11. The upper rib 12 and the lower rib 13 are formed in parallel to the side walls 10b and 11b, respectively. The mating surface of the lid portion 10 with the box portion 11 and the mating surface of the box portion 11 with the lid portion 10 are covered with a flexible film 16. The heat storage material 5 is held in the space formed by the film 16. The heat storage material 5 is preferably a latent heat storage material that undergoes a solid-liquid phase change at a constant temperature, such as sodium phosphate, paraffin, and water.

  A space for holding the transported product 6 is formed near the center of the films 16 and 16. The transported article is covered with the second heat conducting member 7 having good heat conductivity and held in this space. For the second heat conducting member 7, for example, a film or thin plate copper is used.

  The operation and operation of the constant temperature transport container 30 of the present embodiment configured as described above will be described below. The heat conduction member 4 has a sufficiently higher heat conductivity than the individual container 8 and the heat storage material 5 disposed inside, and the heat input from the bottom 1a of the heat insulating container 1 is larger than the heat input from the side surface 1b. Even if the temperature of the bottom portion 1 a rises, the heat that has entered from the bottom portion 1 a is transferred into the heat insulating container 1 by the heat conducting member 4. Even if the transport goods 6 are stacked in the vertical direction inside the heat insulating container 1, the temperature deviation in the vertical direction can be suppressed. Moreover, since the nonuniformity of temperature distribution can be suppressed, in all the individual packaging containers 8 accommodated in the heat insulating container 1, the heat storage material 5 absorbs heat evenly, and the variation in the heat absorption amount of the heat storage material 5 is suppressed. .

Even if the amount of heat stored in the heat storage material 5 of the individual container 8 on the bottom 1a side of the heat insulating container 1 is lost early, the remaining amount of the heat storage amount stored by the heat storage material 5 is different for each individual container 8. Since the heat storage amount of the heat storage material 5 accommodated in the individual container 8 can be transmitted by heat transfer, the temperature increase of the heat conducting member 4 is suppressed.
Thereby, the temperature rise of the transport goods 6 arrange | positioned at the bottom 1a side of the heat insulation container 1 can be suppressed.

  Since the heat storage material 5 and the transported product 6 are held inside the individual packaging container 8 and the heat storage material 5 is disposed around the transported product 6, even if heat is input from the outside of the individual packaging container 8. Unless the temperature of the heat storage material 5 increases, the temperature of the transported product 6 does not increase. Since the heat storage material 5 is provided, the temperature of the transported product 6 can be maintained in a predetermined range for a long time. Since the heat of each individual container 8 is transmitted to the heat conducting member 4, the heat conducting member 4 equalizes the temperature of each individual container 8. Accordingly, it is possible to avoid problems such as the amount of heat input to the heat storage material 5 being biased depending on the location or a part of the heat storage material 5 remaining unmelted. The amount of heat of the heat storage material 5 can be used effectively. In the present embodiment, the example in which the transported article 6 is kept cool by the heat insulating container 1 has been described, but the same effect can be obtained when the transported article 6 is kept warm by the heat insulating container 1.

  Since the transported item 6 is covered with the second heat conducting member 7, even if the heat storage heat amount is lost only by the heat storage material 5 arranged on the lower side of the transported item 6, it remains above or on the side of the transported item 6. The rise in temperature of the transported product 6 can be suppressed using the amount of stored heat. Note that the amount of the heat storage material 5 accommodated inside the individual container 8 may be a constant amount in consideration of productivity, or may be variable according to each transported product 6. When making the quantity of the thermal storage material 5 constant, it sets on the conditions with the largest required thermal storage amount. If an individual container 8 with a different amount of the heat storage material 5 is prepared, it is possible to easily cope with a change in the transportation time of the transported item 6 and the like. In this case, when the heat storage material 5 may be small, the time for storing heat in the heat storage material 5 can be shortened, and the amount of heat can be suppressed. In addition, it can respond, even if the kind etc. of the thermal storage material 5 are changed.

  If the amount of the heat storage material 5 accommodated inside only some of the individual containers 8 is changed, the remaining amount of heat storage varies, but the heat storage material in other individual containers 8 via the heat conducting member 4 The heat storage of 8 is transmitted into the heat insulating container 1. Therefore, the temperature in the heat insulation container 1 can be equalized over a long period of time.

  Since the accommodation space for the heat storage material 5 is formed inside the individual container 8 and the transported product 6 is held between the mating surfaces of the film 16, the heat storage material 5 is easily and reliably disposed around the transported product 6. be able to. Thereby, the malfunction that the temperature of the transported goods 6 partially deviates outside the appropriate range due to the uneven distribution of the heat storage material 5 can be prevented. Since the upper rib 10 and the lower rib 11 formed on the lid portion 10 and the box portion 11 face the heat storage material 5, the contact area between the heat storage material 5 and the individual container 8 increases. Heat exchange between the heat storage material 5 and the individual container 8 is promoted, and the temperature equalization of the individual container 8 is promoted. Since the individual container 8 is molded from a transparent resin, the molten state of the heat storage material 5 can be visually and easily confirmed. Therefore, when the individual container is transported, the heat storage state can be visually grasped, and the mistake of using the individual container 8 that is not sufficiently heat-accumulated can be prevented.

  When the heat storage material 5 undergoes a phase change that is liquid at the time of heat storage and becomes solid at the time of heat dissipation, the heat storage proceeds and the heat storage material 5 accumulates in the lower part of the space that houses the heat storage material 5. In this case, as shown in FIG. 2, the distances between the heat storage material 5 and the top plate portion 10 a and between the heat storage material 5 and the bottom plate portion 11 a are different, so that the upper rib 12 is made longer than the lower rib 13. Thereby, the upper rib 12 and the lower rib 13 reliably reach the inside of the heat storage material 5. When the end face of the upper rib 12 and the end face of the lower rib 13 are brought into contact with the film 16, the temperature of the transported article 6 rises through the ribs 12 and 13 before the temperature of the heat storage material 5 rises. For this reason, the ribs 12 and 13 are configured to be connected only to the top plate portion 10a or the bottom plate portion 11a of the individual container 8.

  In this embodiment, since the bent heat conduction member 4 is disposed in the holding portion 40 of the individual packaging container 8 formed of urethane, when the individual packaging container 8 is taken out from the heat insulating container 1, the upper end of the heat conduction member 4 is disposed. Just lift the edge. Therefore, even when a plurality of individual containers 8 are stacked, the transported product 6 can be easily taken out, and the workability is improved. In order to simplify the configuration, the outer surface of the individual container 8 is covered with a metal having good heat conductivity such as copper, and is also used as the heat conductive member 4 so that the temperature distribution in the heat insulating container 1 is not uniform. Oxidation may be suppressed.

  The vacuum heat insulating material 3 has excellent heat insulating properties in the direction perpendicular to the surface. However, since the outer surface of the vacuum heat insulating material 3 is covered with metal, heat easily leaks from the edge. While making the edge part of the same vacuum heat insulating material 3 approach as much as possible in the circumferential direction, the vacuum heat insulating material 3 is made into a double structure so that the edges of the inner and outer layers do not coincide with the circumferential direction. Thereby, the calorie | heat amount which encloses from a circumferential direction edge part can be suppressed. Since the lower edge part of the vacuum heat insulating material 3 is made lower than the inner bottom surface 1c of the heat insulating container 1 and the heat entrainment from the lower edge part is suppressed, the heat insulating performance of the heat insulating container 1 is improved.

  Since the temperature indicator 21 is provided on the lid 15, it can be confirmed without opening the lid 15 whether the internal temperature is maintained within a predetermined temperature range. In addition, since the temperature sensor 20 is provided inside the lid 15 and the temperature indicator 21 is provided on the surface portion, the wiring connecting the two does not come out and is easy to handle. After the temperature of the temperature sensor 20 deviates from the predetermined range, the temperature of the transported product 6 deviates from the predetermined range. Therefore, if the value of the temperature sensor 20 is within the predetermined range, the temperature of the transported product 6 falls outside the predetermined range. There is nothing. In this embodiment, since the temperature of the heat conducting member 4 is adopted as the representative temperature in the heat insulating container 1, the heat insulating container 1 can always be managed on the safe side.

  FIG. 4 shows a state in which a plurality of the constant-temperature transport containers 30 shown in FIG. 1 are accommodated in the transport container 31 and transported. In FIG. 4, a plurality of individual containers 8 each storing a transported product 6 are stored in each constant temperature transport container 30. The transport container 31 is an openable / closable box-shaped container having a main body 33 in which a plurality of holes having a height similar to that of the constant temperature transport container 30 is formed, and a lid 34 covering the upper surface of the stored constant temperature transport container 30. It is. A temperature display section 32 that can collectively display the temperatures detected by the temperature sensor 20 of each constant temperature transport container 30 stored therein is provided on the side surface on the front side.

  According to the present embodiment, it is possible to grasp the temperature in each constant temperature transport container 30 without opening and closing the lid 34 of the transport container 31. Since the transport container 31 functions as a heat insulating material for the periphery of the transport container 31, reducing the number of times of opening and closing the lid 34 is advantageous in terms of maintaining heat insulation, and increases the temperature of the transported product 6. It can be kept at a predetermined temperature for a time. Note that the temperature measured by the temperature sensor 20 of each constant temperature transport container 30 is displayed on the temperature display unit 32 of the transport container 31 by switching the contact of a switch (not shown). Needless to say, the temperature display unit 32 may display a plurality of temperatures.

  The temperature indicator 21 and the temperature display part 32 have an alarm for notifying the transporter that the temperature detected by each temperature sensor 20 has deviated from a predetermined range. The alarm enables the transporter to check the sealed state of the heat storage material 5 and the container 31 for transport, the constant temperature transport container 30, and the individual container 8, and can take necessary actions quickly, and the abnormal temperature of the transported goods. An increase or a decrease in temperature can be avoided.

  The temperature indicator 21 or the temperature display unit 32 may be provided with means for predicting the temperature of the transported item 6. The predicting means predicts a subsequent temperature change from the temperature value detected by the temperature sensor 20 and its temporal change rate. When the predicted temperature deviates from the predetermined range, the transporter is notified in advance. As this predicting means, for example, those applied to an electronic thermometer or the like can be used. If an electronic thermometer is used, installation becomes easy at low cost. The transporter may take appropriate measures such as improving the situation around the transport container 31 or contacting the transport source or transport destination before the temperature of the transported product 6 deviates from the predetermined range. it can. This makes it possible to minimize damage due to temperature changes of the transported goods 6. In addition, a function for notifying the transport source or the transport destination of the temperature prediction result may be added to the temperature display 21 or the temperature display unit 32 itself, or the temperature change history of the transported product 6 may be stored.

  Another embodiment of the constant temperature transport container 30 according to the present invention is shown in a longitudinal sectional view in FIG. This embodiment is different from the embodiment shown in FIG. 1 in that the transport article 6 is covered with a heat insulating material 9 instead of the individual container 8, and the transport goods 6 covered with the heat insulating material 9 are laminated. The heat storage material 5 is inserted between the heat insulating materials 9 in the vertical direction. The heat storage material 5 is also laminated on the lower side of the lowermost heat insulating material 9 and on the upper side of the uppermost heat insulating material 9. As the heat insulating material 9, the above vacuum heat insulating material may be used, or a commercially available heat insulating material may be used.

  In this embodiment, since the dedicated individual container 8 is not used, the manufacture is easy. Since the heat storage material 5 can be formed in a plate shape, the volume may be small when the heat storage material 5 is solidified or melted in advance, and a large heating or cooling area can be secured. Therefore, the processing time required for solidification or melting can be shortened. When the number of transport items 6 is small, the space 9 inside the constant temperature transport container 30 can be easily filled with the heat insulating material 9 and the heat storage material 5. When the heat storage material 5 is filled, the heat storage amount increases, and the heat retaining performance of the transported product can be easily enhanced. It is suitable when the temperature conditions such as outside air are severe or when the transportation time is long. In that case, for example, many heat storage materials 5 are arranged above. Even if the heat storage amount is uneven, the heat conduction member 4 can measure the temperature uniformity, and the heat storage effect can be enjoyed over a long period of time. It is possible to reliably extend the transportable time, and it is not necessary to add the heat storage material 5 excessively. In the present embodiment, the heat storage material 5 and the transport product 6 are alternately stacked, but it is not always necessary to stack them alternately. For example, the heat storage material 5 may be a single layer and only the transport product 6 may be stacked.

  FIG. 6 is a longitudinal sectional view showing still another embodiment of the constant temperature transport container according to the present invention. In this embodiment, the transported product 6 covered with the heat insulating material 9 is laminated, the whole laminated heat insulating material 9 is covered with the metal second heat conducting member 7, and the outer peripheral portion of the second heat conducting member 7 is covered. The heat storage material 5 is filled. Since a plurality of the heat storage materials 5 enclosed in the plate-like container are arranged in the heat insulating container 1, the volume of the heat storage material 5 alone can be reduced. In addition, since the second heat conducting member 7 is arranged inside the heat storage material 5 and the heat insulating material 9 is arranged inside the heat storage material 5, even if the temperature of a part of the heat storage material 5 falls below a predetermined temperature, the other Since the amount of heat stored in the heat storage material 5 is transmitted via the second heat conducting member 7, it is possible to avoid a local temperature drop from occurring inside the second heat conducting member.

  In the embodiment shown in FIGS. 1 and 5, the heat conducting member 4 covers the upper, lower, left and right surfaces of the transported article 6, but the heat conducting member 4 may be provided only in a part as in the present embodiment. Good. In the present embodiment, since the amount of the heat conducting member 4 is reduced, the constant temperature transport container 30 is reduced in weight.
