Description

  The present invention relates to a transport container that is placed in a refrigerator or freezer and cools the stored items by introducing cold air into the interior.

  Conventionally, Patent Document 1 discloses a transport container having ventilation holes on a bottom surface portion and a side surface portion.

  In the conventional example shown in Patent Document 1, the transport container is provided with a lid that can be freely opened and closed on the upper opening frame portion, and a ventilation hole is also formed in the lid in order to improve air permeability to the inside. Further, ventilation holes are also formed in the upper opening frame.

  In the conventional example shown in Patent Document 1, when stacking transport containers in upper and lower stages, the upper transport container is stacked on the lid of the lower transport container. Yes.

  Therefore, in this conventional example, when the stored item is cooled in a refrigerator or a freezer, cold air enters from the ventilation hole formed in the side surface portion to cool the stored item, and the cold air is It flows out from the ventilation hole formed in the part or flows from the inside of the upper transport container into the lower transport container. Here, in the above conventional example, there is a problem that the vent hole is blocked by the stored item. Moreover, external cold air is not introduced into the lower transport container from the overlapping portion of the lower transport container and the upper transport container.

  There is also known a transport container that is not provided with a lid that can be stacked up and down in multiple stages. This transport container is formed with ventilation holes in the side surface and the bottom surface, provided with a fitting portion on the bottom surface portion of the transport container, and the fitted portion of the upper transport container with the upper opening frame portion of the lower transport container. It is designed to be stacked up and down.

  This is because cold air does not enter from the outside at the fitting portion of the upper transport container and the upper opening frame of the lower transport container, so the upper end inside the lower transport container There is a problem that the part around the part is not cooled by the cold air entering directly from the outside.

  In addition, it is conceivable to form ventilation holes penetrating from the outer surface side to the inner surface side in the upper opening frame of the transport container that is stacked so that the fitting portion fits into the upper opening frame portion. When the fitting part is fitted into the upper opening frame part, the ventilation hole provided in the upper part of the upper opening frame part is closed by the fitting part, and eventually the upper end inside the lower transport container from the outside in the fitting part. Outside air cannot be allowed to enter the portion, and even if a vent hole is formed in the upper opening frame portion, cold air can only be introduced from the outside below the fitting portion.

In addition, if the stored item in the transport container closes the ventilation hole provided in the bottom surface part, closes the ventilation hole provided in the side surface part, or if the stored item is tall, the upper opening frame part In such a case, the entry of cold air from the outside is obstructed, and the stored items cannot be effectively cooled.
JP 2002-19779 A

  The present invention has been invented in view of the above-described conventional problems, and has a simple configuration, while suppressing rattling at the fitting portion between the fitting portion and the upper opening frame portion, and from the fitting portion to the outside. It is an object of the present invention to provide a transport container capable of effectively cooling by introducing cold air therein.

  In order to solve the above-mentioned problems, a transport container according to the present invention is a transport container A that can be stacked up and down in a plurality of stages and has vent holes 3 in the bottom surface portion 1 and the side surface portion 2. A fitting portion 5 that can be fitted into the upper opening frame portion 4 of the lower transportation container A is provided on the bottom surface portion of the container A, and the fitting portion 5 of the transportation container A is fitted into the upper opening frame portion 4. In the state where the upper and lower frame parts 4 are stacked in the vertical direction, the outer and lower transport containers A are provided on one or both of the outer surface of the fitting part 5 and the inner surface of the upper opening frame part 4 in the fitting part of the fitting part 5 and the upper opening frame part 4. And a ventilation recess 7 serving as a cold air introduction passage 6 for introducing cold air from the outside into the lower transport container A.

  By adopting such a configuration, when the stored containers are put in the transport container A, the transport containers A are stacked up and down in multiple stages and placed in the refrigerator and freezer. It is possible to introduce external cold air into the upper end portion of the lower transport container A from the cool air introduction passage 6 provided in the fitting section between the lower fitting part 5 and the upper opening frame part 4 of the lower transport container A. it can. In addition, the cold air introduction passage 6 is formed by forming a ventilation recess 7 on one or both of the outer surface of the fitting portion 5 and the inner surface of the upper opening frame portion 4, and therefore other than the ventilation recess 7 in the fitting portion. As in the conventional case, the cold air can be introduced even in a dimensional relationship in which the inner surface of the fitting portion 5 and the outer surface of the upper opening frame portion 4 are fitted almost closely or with a slight gap as in the conventional case. In this way, it is possible to prevent rattling in the fitting portion between the fitting portion 5 and the upper opening frame portion 4 while the cold air can be introduced from the outside in the fitting portion.

  Moreover, while providing the mounting part 8 for mounting in the upper opening frame part 4 when stacking up and down in the lower part of the container A for conveyance, an outer surface is set inside the mounting part 8 in the lower part of the mounting part 8. It is preferable to provide the retracted fitting portion 5 and to form a recess 9 in a part of the placement portion 8 so as to communicate with the ventilation recess 7 and the outside.

  By adopting such a configuration, the air that becomes the cold air introducing passage 6 formed in the fitting portion between the fitting portion 5 and the upper opening frame portion 4 through the recessed portion 9 provided in the mounting portion 8 is used. It can be introduced into the recess 7 at the upper end in the lower transport container A.

  Moreover, it is preferable that the upper part of the ventilation recess 7 formed in the inner surface of the upper opening frame part 4 is opened to the outside when stacked up and down.

  By setting it as such a structure, cold air can be directly introduce | transduced into the ventilation | gas_flowing recessed part 7 formed in the inner surface of the upper opening frame part 4 from the outside, and can be introduced into the upper end part in the lower container A.

  Moreover, it is preferable that the ventilation recess 7 formed on the inner surface of the upper opening frame portion 4 is made lower as it goes inward.

  By adopting such a configuration, the cold air introduced into the ventilation recess 7 can be made to flow obliquely downward, and the cold air can be made to flow obliquely downward from the corner of the upper end portion in the lower upper opening frame portion 4. Cold air can be effectively introduced from the fitting portion inside the upper end portion in the transport container A.

  Moreover, it is preferable to form a lower opening 10 that allows cool air to flow into the lower transport container A at a position away from the upper opening frame 4 in the ventilation recess 7 formed on the outer surface of the fitting portion 5.

  By adopting such a configuration, the cool air introduced into the vent recess 7 is effectively fitted into the inner side of the upper end portion of the lower transport container A at a position away from the upper opening frame portion 4 from the inner portion, thereby effectively cooling the cool air. Can be introduced.

  Further, it is preferable to form a lower ventilation hole 11 communicating with the inside of the lower end portion of the transport container A in the concave portion 9 provided in a part of the placement portion 8.

  With such a configuration, external cold air can be introduced into the lower end portion of the upper transport container A through the lower ventilation hole 11 provided in the recess 9.

  As described above, the present invention communicates the outside and the inside of the lower transportation container with one or both of the outer surface of the fitting portion and the inner surface of the upper opening frame portion in the fitting portion between the fitting portion and the upper opening frame portion. As a result, it forms a ventilation recess that serves as a cold air introduction passage for introducing cold air from the outside into the lower transport container, so that it has a simple structure and rattling at the fitting portion between the fitting portion and the upper opening frame portion. However, the inside of the lower transport container can be effectively cooled by introducing external cold air directly into the lower transport container from the fit portion between the fit portion and the upper opening frame portion. In addition, when storing things in a transport container, depending on how they are stored, the ventilation holes provided on the bottom and side portions may be blocked with the stored goods, but transport is premised on stacking up and down. In the container, the upper end of the stored item is always lower than the fitting portion. Therefore, the passage for introducing cold air in the present invention is not blocked by the stored item, and therefore, the upper end portion in the container for transportation. It is possible to reliably introduce cold air from the outside.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  In the accompanying drawings, an example of a folding transport container as the transport container A is shown.

  As shown in FIGS. 1 to 5, the transport container A includes a bottom plate portion 12, a pair of folding side plates 13, a pair of rotating side plates 14, and an upper opening frame portion 4.

  The bottom plate portion 12 is provided with a mounting portion 8 on the outer peripheral portion, and a fitting portion 5 whose outer surface is drawn inward from the mounting portion 8 protrudes downward from the mounting portion 8.

  The folding side plate 13 is configured by connecting the lower end of the upper side plate half 15 and the upper end of the lower side plate half 16 so as to be foldable in an inward shape by a shaft support means. A pair of opposing sides (in the embodiment, opposing long sides) are respectively pivotally supported at the lower end of the lower plate half 16 of the folding side plate 13 by pivot support means, and the opposed pair of the upper opening frame 4. The upper end of the upper plate half 15 is pivotally supported by the pivotal support means at the lower end of each side (long sides facing each other in the embodiment).

  Moreover, the upper end part of the rotation side plate 14 is pivotally supported by the pivotal support means at the lower end part of the other pair of sides facing the upper opening frame part 4, respectively.

  In the transport container A having the above-described configuration, the folding side plates 13 are spread so that the lower plate half 16 and the upper plate half 15 are straight up and down, and then both the rotating side plates 14 are rotated. By making it stand, it is assembled into a box shape having an open top as shown in FIG. In this case, the lower end portion of the rotating side plate 14 is detachably locked to the bottom plate portion 12 by the locking means, and the side end portion of the rotating side plate 14 is detachably locked to the folding side plate 13 by the locking means. Thus, the box shape is maintained.

  Here, in the transport container A of the present embodiment, the bottom plate portion 12 constitutes the bottom surface portion 1, and the folding side plate 13 and the rotation side plate 14 constitute the side surface portion 2.

  A plurality of ventilation holes 3 are formed in each of the bottom plate portion 12 constituting the bottom surface portion 1, the folding side plate 13 constituting the side surface portion 2, and the rotating side plate 14.

  In the embodiment shown in the accompanying drawings, a plurality of support protrusions 17 for supporting the stored items are provided on the upper surface of the bottom plate portion 12 and the inner surface of the rotating side plate 14, respectively.

  In the state assembled in the box shape as shown in FIG. 1, the stored items are stored in the transport container A, but in the embodiment of FIG. It is fitted and stored so as to support the lower edge and both side edges of the substantially plate-like storage item. An example of the plate-like storage is a cold storage agent, but of course, it is not limited to this.

  The container A for storing the stored items is stacked up and down, and the stored items stored in the refrigerator or freezer are cooled. When the transport containers A are stacked up and down, the placement portion 8 of the upper transport container A is placed on the upper surface of the upper opening frame 4 of the lower transport container A as shown in FIG. The fitting portion 5 of the upper transport container A is fitted into the upper opening frame portion 4 of the lower transport container A so that stable stacking can be performed.

  In the refrigerator or freezer, cold air is introduced into the transport container A from the vent hole 3 provided in the side surface portion 2, and further passes through the vent hole 3 provided in the bottom surface portion 1 of the upper transport container A. It is introduced into the lower transport container A.

  Thus, by introducing cool air into the interior, the stored items are cooled.

  On the other hand, when the stored item is not stored, both the rotating side plates 14 are rotated so as to be turned sideways, both the folding side plates 13 are folded inwardly, and the rotating side plates 14 are placed on the folded folding side plate 13. Are folded and made compact as shown in FIG.

  In the transport container A having the above-described configuration, in the present invention, the fitting part 5 is fitted into the fitting part 5 between the upper transport container A and the upper opening frame part 4 of the lower transport container A. For introducing cold air from the outside into the lower transport container A by communicating the outside and the lower transport container A with one or both of the outer surface and the inner surface of the upper opening frame 4 A ventilation recess 7 is formed.

  FIG. 6 shows an example in which ventilation recesses 7 are provided on both the outer surface of the fitting portion 5 and the inner surface of the upper opening frame portion 4, and the cold air introduction passage 6 is formed in the fitting portion by both ventilation recesses 7. is there.

  Moreover, each embodiment of FIG.6, FIG.8, FIG.9 has shown the example which provided the ventilation recess 7 in the inner surface of the upper opening frame part 4, and formed the channel | path 6 for cold air introduction.

  Further, FIG. 10 shows an example in which the ventilation recess 7 is provided only on the outer surface of the fitting portion 5 to form the cool air introduction passage 6 without providing the ventilation recess 7 on the inner surface of the upper opening frame portion 4. It is. In this example, the upper opening frame portion 4 can be vented without providing the ventilation recess 7, so that the strength of the upper opening frame portion 4 does not decrease.

  The cold air introduction passage 6 formed in the fitting portion as described above communicates with the introduction port 20 whose upstream end is opened to the outside, and the outlet 21 where the downstream end communicates with the lower transport container A. The external cold air is introduced into the lower transport container A through the cold air introduction passage 6 formed in the fitting portion.

  Several examples will be described with respect to an example in which the introduction port 20 opened to the outside is formed.

  In each of the embodiments shown in FIGS. 6 and 8 to 10, a recess 9 that communicates with the ventilation recess 7 and the outside is formed in a part of the mounting portion 8, thereby constituting the introduction port 20. That is, the ventilation recess 7 provided in a part of the mounting portion 8 has an outer surface side and a lower surface opened, and external cold air is introduced into the recess 9 from the opening on the outer surface side of the recess 9. Is introduced into the upper end portion of the cold air introduction passage 6 from the opening on the lower surface of the recess 9 and is introduced from the lower end portion of the cold air introduction passage 6 into the upper end portion of the lower transport container A. It has become.

  In the embodiment shown in FIGS. 6, 8, and 10, it is not necessary to form the introduction port 20 on the outer surface of the upper opening frame portion 4, and the appearance is good and the strength reduction of the upper opening frame portion 4 is prevented. it can. Further, the bottom of the upper transport container A can be prevented from being caught by the upper opening frame portion 4 of the lower transport container A by sliding during stacking.

  Further, FIG. 9 shows that the upper part of the ventilation recess 7 formed on the inner surface of the upper opening frame part 4 is communicated with the outside, and in addition, a part of the mounting part 8 communicates with the outside and the ventilation recess 7. The example which formed the recessed part 9 to show is shown, and in this embodiment, the upper part of the ventilation recessed part 7 formed in the inner surface of the recessed part 9 and the upper opening frame part 4 comprises the inlet 20.

  In the embodiment shown in FIG. 9, cold air can be introduced from the outside through the recess 9 and the upper portion of the ventilation recess 7 formed in the inner surface of the upper opening frame portion 4, thereby increasing the amount of cold air introduced from the outside. Can do.

  Although not shown, the mounting portion 8 is not provided with a recess 9 and only the upper portion of the ventilation recess 7 formed on the inner surface of the upper opening frame portion 4 is opened to the outside when stacked up and down. (That is, an example in which the recess 9 is not provided in FIG. 9). In this embodiment, the upper portion of the ventilation recess 7 formed on the inner surface of the upper opening frame portion 4 communicates directly with the outside to form the introduction port 20, and cool air is directly introduced into the ventilation recess 7 from the outside. Thus, it can be introduced into the upper end of the lower transport container A. Moreover, in this embodiment, it is not necessary to provide the introduction port 20 in the mounting part 8, and stable mounting is possible.

  Next, an example of the outlet 21 will be described.

  The embodiment shown in FIGS. 6 and 10 is an example in which the outlet 21 is configured by forming the lower opening 10 that opens downward in the ventilation recess 7 formed on the outer surface of the fitting portion 5. In this embodiment, the cool air is caused to flow directly into the lower transport container A from the lower opening 10 of the ventilation recess 7 that forms the cool air introduction passage 6. In this embodiment, since the lower opening 10 that opens downward is formed on the lower surface of the ventilation recess 7 formed on the outer surface of the fitting portion 5 to form the outlet port 21, the inner end of the lower opening 10 is the upper portion. Therefore, the cold air introduced into the ventilation recess 7 is moved from the upper opening frame 4 to the inner side. Thus, it is possible to effectively introduce cold air toward the inside of the upper end portion in the lower transport container A at a position away from the front.

  Further, as shown in FIGS. 8 and 9, a ventilation recess 7 is formed on the inner surface of the upper opening frame portion 4, and a lower end portion of the ventilation recess 7 is formed below the fitting portion 5. The part below the fitting part 5 of 7 may constitute the outlet 21.

  Further, although not shown, a ventilation recess 7 is formed on the outer surface of the fitting portion 5 to form a lower opening 10 that opens downward on the lower surface of the ventilation recess 7, and the upper opening frame portion 4. By forming the ventilation recess 7 on the inner surface and forming the lower end portion of the ventilation recess below the fitting portion 5, the ventilation recess 7 formed on the inner surface of the fitting portion 5 and the inner surfaces of the upper opening frame portion 4. The outlets 21 may be formed in both of the ventilation recesses 7 formed in the above. In this case, the amount of cool air flowing from the cool air introduction passage 6 into the lower transport container A can be increased.

  Further, when the ventilation recess 7 is formed in the upper opening frame portion 4, it is preferable that the ventilation recess 7 formed on the inner surface of the upper opening frame portion 4 becomes lower as it goes inward. 6 to 9 show an example in which the ventilation recess 7 formed on the inner surface of the upper opening frame portion 4 is inclined so as to become lower toward the inner side.

  In this way, when the ventilation recess 7 formed on the inner surface of the upper opening frame portion 4 is configured to become lower as it goes inward, the cold air introduced into the ventilation recess 7 is allowed to flow obliquely downward, so that the lower upper opening frame The cool air can flow obliquely downward from the corner of the upper end portion in the portion 4, and the cool air can be effectively introduced from the fitting portion inside the upper end portion in the lower transport container A.

  Here, as shown in FIG. 6, the ventilation recess 7 formed on the inner surface of the upper opening frame portion 4 is configured to become lower toward the inside, and the ventilation recess 7 formed on the outer surface of the fitting portion 5. When both of the configurations of forming the lower opening 10 opened downward on the lower surface are provided, the cold air flows in the direction away from the upper opening frame portion 4 as a flow that flows obliquely downward in the cold air introduction passage 6, and the upper opening Cold air can be more reliably introduced toward the inside of the upper end portion in the lower transport container A at a position away from the frame portion 4.

  In any of the embodiments, in the present invention, at the fitting portion between the fitting portion 5 and the upper opening frame portion 4, one or both of the outer surface of the fitting portion 5 and the inner surface of the opening frame portion 4 is used for transportation between the outside and the lower stage. A vent recess 7 serving as a cold air introduction passage 6 is formed to communicate with the inside of the container A and introduce cold air into the lower transport container A from the outside, so that the lower part of the upper transport container A is fitted. External cold air can be introduced into the lower transport container A from the fitting portion between the portion 5 and the upper opening frame 4 of the lower transport container A.

  By the way, in the transportation container A in which the fitting portion 5 is fitted in the upper opening frame portion 4 and stacked vertically as in the present invention, the upper end of the stored item put in the transportation container A is the fitting portion 5. When it is fitted into the upper opening frame 4 and stacked up and down, it is generally stored so as not to hit the lower surface of the upper transport container A (the lower surface of the fitting portion 5). There is a gap between the upper end of the stored item stored in the container A and the lower surface of the upper transport container A.

  In the present invention, by forming the cool air introduction passage 6 in the fitting portion between the fitting portion 5 and the upper opening frame portion 4, the upper end and the upper portion of the stored item stored in the lower transport container A are formed. Cold air can be introduced from the outside into the gap between the lower surface of the transport container A, and cool air is introduced into the inside of the upper end of the lower transport container A from the gap and stored in the lower transport container A. The stored items can be cooled almost equally and effectively.

  Further, since the cold air introduction passage 6 is formed by forming a ventilation recess 7 in one or both of the outer surface of the fitting portion 5 and the inner surface of the upper opening frame portion 4, other than the ventilation recess 7 in the fitting portion. As in the conventional case, the cold air can be introduced even in a dimensional relationship in which the inner surface of the fitting portion 5 and the outer surface of the upper opening frame portion 4 are fitted almost closely or with a slight gap as in the conventional case. it can. Therefore, rattling at the fitting portion between the fitting portion 5 and the upper opening frame portion 4 can be prevented while cold air can be introduced from the outside at the fitting portion.

  Of course, even if there is a slight gap between the outer surface of the fitting portion 5 and the inner surface of the upper opening frame portion 4, the fitting portion 5 is displaced and one outer surface of the fitting portion 5 is the upper opening frame portion. 4, even in the abutting portion, even in this abutting portion, the ventilation recess 7 is formed in the outer surface of the fitting portion 5 or the inner surface of the upper opening frame portion 4, so that cool air can be reliably ventilated. .

  Further, when a plate-shaped stored item is placed in the transport container A and supported by the support protrusion 17, the position of the cool air introduction passage 6 is parallel to the plate-shaped stored item supported by the support protrusion 17 ( If it is provided in a direction parallel to the protruding direction of the support protrusion 17, cooling can be performed more efficiently.

  In addition, a ventilation recess 7 is formed on the outer surface of the fitting portion 5, a lower opening 10 that opens downward is formed in the ventilation recess 7 to constitute a lead-out port 21, and a part of the mounting portion 8 is further formed. In the case where the introduction recess 20 is formed by forming the ventilation recess 7 provided in the fitting portion 5 and the outside, the cooling air is supplied from the outside without providing the ventilation recess 7 in the upper opening frame portion 4. Therefore, in this case, even if the ventilation recess 7 is provided in the upper opening frame 4, the ventilation recess 7 can be reduced, and the introduction port 20 communicated with the ventilation recess 7 to the outside. Even when forming, the inlet 20 can be made small. As described above, in the present embodiment, the ventilation recess 7 is not provided in the upper opening frame portion 4 or may be small, and may be small even if the introduction port 20 is provided. As a result, the upper opening frame portion is small. 4 can be efficiently cooled while preventing a decrease in strength.

  Further, in each embodiment shown in the attached drawings, a lower ventilation hole 11 communicating with the lower end portion of the transport container A is formed in a recess 9 provided in a part of the mounting portion 8, and provided in the recess 9. The external cold air can be introduced into the lower end portion of the upper transport container A through the lower ventilation hole 11 so that the cool air is introduced into the lower portion of the upper transport container A from the recess 9. Can be introduced.

  In this case, as shown in the embodiments of FIGS. 6 and 8 to 10, when the concave portion 9 serves as the inlet 20 of the cold air introduction passage 6, the cold air introduced from the concave portion 9 is transferred to the lower transport container. It can introduce | transduce into the upper end part in A, and the lower end part in the upper conveyance container A, and can raise a cooling effect more by simple structure.

  In the embodiment shown in the accompanying drawings, the example of the folding and transporting container has been described as the transporting container A, but it is not necessarily limited to the folding and transporting container. Of course, as long as it has the ventilation hole 3 in the side surface portion 2, it may be an integrally molded transport container having an open top.
