Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing the packaging container 1 of the present embodiment. As shown in FIG. 1, the packaging container 1 of the present embodiment includes a plurality of packs 2 filled with fruits F (shown in FIG. 11) and a shipping box 3 containing the packs 2.

Pack 2 can be packed with a plurality of (two in this embodiment) fruit F. The pack 2 is preferably made of a transparent resin. As such a pack 2, the pack 2 used at the time of selling a normal fruit F can be adopted, so that the cost can be reduced.

FIG. 2 is a perspective view of the pack 2. As shown in FIG. 2, the pack 2 includes a fruit holding portion 4 for individually holding a plurality of fruits F (shown in FIG. 11) and a flange portion 5 protruding laterally outward from the fruit holding portion 4. It is desirable to include. The flange portion 5 of the present embodiment has a substantially rectangular shape in a plan view, and has four corner portions 5a (three corner portions 5a are shown in FIG. 2).

The pack 2 of the present embodiment has an integral structure in which a pack main body 2A in which the fruit F is packed and a pack lid 2B covered from above the fruit F are connected by a connecting portion 2C. It is desirable that the pack main body 2A includes a fruit holding portion 4A on the main body side and a flange portion 5A on the main body side. Further, it is desirable that the pack lid portion 2B includes a fruit holding portion 4B on the lid portion side and a flange portion 5B on the lid portion side.

FIG. 3 is a perspective view of the shipping box 3, and FIG. 4 is a plan view of the shipping box 3. Further, FIG. 5 is a partially enlarged view of FIG. As shown in FIGS. 3 to 5, the transport box 3 of the present embodiment has a bottom plate 6, four side walls 7 extending upward from the periphery of the bottom plate 6, and four corner portions 5a of the flange portion 5 of the pack 2. Includes a plurality of support portions 8 for supporting the vehicle from below.

In such a transport box 3, since the pack 2 is supported only by the four corners 5a of the flange portion 5, it is difficult for the impact during transportation to be transmitted to the fruit F (shown in FIG. 11). Therefore, the transport box 3 can transport the fruit F contained therein without damaging it.

The bottom plate 6, the side wall 7, and the support portion 8 are integrally formed of, for example, a foamed resin such as expanded polystyrene, expanded polyethylene, or expanded polypropylene. Since the foamed resin has a function of absorbing the impact during transportation, the transportation box 3 can further suppress the impact during transportation from being transmitted to the fruit F. Further, it is easy to maintain the inside of such a transport box 3 in an environment suitable for the contained fruit F.

FIG. 6 is a bottom view of the transport box 3, and FIG. 7 is a cross-sectional view taken along the line AA of FIG.

The bottom plate 6 of the present embodiment has a sealing structure that blocks the flow of air. That is, the bottom plate 6 does not have a ventilation portion that communicates the upper surface 6a and the lower surface 6b.

The transport box 3 having such a bottom plate 6 is, for example, ethylene generated from the fruit F (shown in FIG. 11) housed in the lower transport box 3 when being stacked and transported (shown in FIG. 12). There is no risk that gas or the like will come into direct contact with the fruit F contained in the transport box 3 above it.

FIG. 8 is a front view of the shipping box 3, and FIG. 9 is a side view of the shipping box 3. As shown in FIGS. 7 to 9, the bottom plate 6 of the present embodiment employs a stepped structure in which the central portion projects downward. Such bottom plates 6 are stacked because, for example, when the transport boxes 3 are stacked and transported, the step structure of the bottom plate 6 of the upper transport box 3 fits inside the lower transport box 3. There is no risk that the shipping box 3 will shift.

As shown in FIG. 3, the side wall 7 includes an inner surface 7a located inside the transport box 3 and an outer surface 7b located outside the transport box 3. It is desirable that the side wall 7 has a ventilation portion 9 through which air can flow. The ventilation portion 9 communicates the inner surface 7a and the outer surface 7b. Therefore, the inside of the transport box 3 can introduce air from the outside and can be maintained in an environment suitable for the contained fruit F (shown in FIG. 11).

Each side wall 7 of the present embodiment has one ventilation portion 9. A plurality of ventilation portions 9 may be formed on each side wall 7, for example. The number and size of the vents 9 can be appropriately determined according to the type of fruit F contained in the transport box 3.

As shown in FIGS. 3, 8 and 9, the four side walls 7 of the present embodiment include a pair of first side walls 7A having a relatively small length and a pair of second side walls 7 having a relatively large length. Includes side wall 7B.

The second side wall 7B of the present embodiment has one second ventilation portion 9B formed in a concave shape from the upper portion thereof. That is, the ventilation portion 9 includes the first ventilation portion 9A and the second ventilation portion 9B. Each ventilation portion 9 may have a hole shape, for example.

As shown in FIGS. 3 and 8, each first side wall 7A has a recess 10 at a boundary portion with the bottom plate 6. The recess 10 can be suitably used when carrying the transport box 3.

As shown in FIG. 7, the support portion 8 of the present embodiment extends upward from the upper surface 6a of the bottom plate 6. It is desirable that the support portion 8 is provided with a support surface 8a parallel to the upper surface 6a of the bottom plate 6 on the upper end side thereof. The height H1 from the upper surface 6a of the bottom plate 6 to the support surface 8a of the support portion 8 is, for example, 40% to 60% of the height H2 from the upper surface 6a of the bottom plate 6 of the side wall 7.

As shown in FIGS. 3 and 5, it is desirable that each support portion 8 has a rib 11 projecting upward from the support surface 8a. The rib 11 is formed, for example, in a straight line. Such ribs 11 can come into contact with the straight portion of the flange portion 5 of the pack 2 to regulate the horizontal movement of the pack 2. It is desirable that the height of the rib 11 from the support surface 8a is equal to or slightly larger than the height of the end portion of the flange portion 5 of the pack 2.

As shown in FIGS. 3 to 5, the support portion 8 of the present embodiment includes a side wall side support portion 12 arranged along the side wall 7 and a central side support portion 13 not in contact with the side wall 7. ..

As shown in FIG. 4, the side wall side support portion 12 includes, for example, a first side wall side support portion 12A that contacts only the first side wall 7A, a second side wall side support portion 12B that contacts only the second side wall 7B, and a second side wall side support portion 12. It includes a third side wall side support portion 12C in contact with the first side wall 7A and the second side wall 7B.

In a plan view, it is desirable that the first side wall side support portion 12A and the second side wall side support portion 12B have a substantially T shape. Such a first side wall side support portion 12A and a second side wall side support portion 12B can reliably support the four corner portions 5a (shown in FIG. 5) of the flange portion 5 of the pack 2. Further, such a first side wall side support portion 12A and a second side wall side support portion 12B have a function of reinforcing the side wall 7.

In a plan view, the third side wall side support portion 12C is preferably substantially L-shaped. Such a third side wall side support portion 12C can reliably support the four corner portions 5a of the flange portion 5 of the pack 2. Further, the third side wall side support portion 12C has a function of reinforcing the side wall 7.

In a plan view, the central support portion 13 preferably has a substantially cross shape. Such a central support portion 13 can reliably support the four corner portions 5a of the flange portion 5 of the pack 2.

FIG. 10 is a cross-sectional view taken along the line BB of FIG. As shown in FIGS. 3 to 5 and 10, the central support portion 13 has a circular bottomed hole 14 in the center thereof. Such a bottomed hole 14 can be used when lifting the corner portion 5a of the flange portion 5 of the pack 2 supported by the central support portion 13, and makes it easy to take out the pack 2. Further, since the bottomed hole 14 of the central support portion 13 suppresses an excessively thick portion, the material can be reduced and the quality of the transport box 3 can be made more uniform.

As shown in FIGS. 3, 4, 7, and 10, a space portion 15 through which air can flow is formed between all the support portions 8 of the present embodiment. That is, the space portion 15 is formed between the side wall side support portions 12, and is also formed between the side wall side support portion 12 and the central side support portion 13 and between the central side support portions 13. Therefore, the inside of the transport box 3 can be maintained in an environment suitable for the contained fruit F (shown in FIG. 11) by an appropriate air circulation.

As shown in FIG. 7, the length L1 of the space portion 15 formed between the second side wall side support portion 12B and the central side support portion 13 at the position of the upper surface 6a of the bottom plate 6 is the length L1 of the second side wall 7B. The distance P1 from the inner surface 7a to the center of the central support portion 13 is preferably 35% or more. If the length L1 is smaller than 35% of the distance P1, the lateral air circulation inside the transport box 3 may not be performed smoothly.

The length L2 of the space portion 15 formed between the second side wall side support portion 12B and the central side support portion 13 at the position of the support surface 8a is preferably 40% or more of the distance P1. If the length L2 is smaller than 40% of the distance P1, the vertical air circulation inside the transport box 3 may not be performed smoothly.

As shown in FIG. 10, the length L3 of the space portion 15 formed between the central support portions 13 at the position of the upper surface 6a of the bottom plate 6 is 20 of the distance P2 between the centers of the adjacent central support portions 13. It is preferably% or more. If the length L3 is smaller than 20% of the distance P2, the lateral air circulation inside the transport box 3 may not be performed smoothly.

The length L4 of the space portion 15 formed between the central support portions 13 at the position of the support surface 8a is preferably 35% or more of the distance P2. If the length L4 is smaller than 35% of the distance P2, the vertical air circulation inside the transport box 3 may not be performed smoothly.

The space portion 15 formed between the first side wall side support portion 12A and the central side support portion 13 and the space portion 15 formed between the side wall side support portions 12 also have substantially the same length as the above-mentioned space portion 15. It is desirable to have. Such a space portion 15 can smoothly circulate air throughout the inside of the transport box 3.

FIG. 11 is a cross-sectional view of the packaging container 1 at the same position as in FIG. As shown in FIGS. 1, 5 and 11, the packaging container 1 of the present embodiment includes the above-mentioned transport box 3 and a plurality of packs 2 housed in the transport box 3. In the present embodiment, the four corners 5a of the flange portion 5 of the pack 2 are supported by the support surface 8a of the support portion 8 of the transport box 3.

In the packaging container 1 of the present embodiment, a gap 16 is provided between the upper surface 6a of the bottom plate 6 of the transport box 3 and the bottom of the pack 2. Therefore, in the packaging container 1, since the fruit holding portion 4 of the pack 2 does not come into contact with the transport box 3, it is difficult for the impact during transportation to be transmitted to the fruit F. Further, the gap 16 promotes the circulation of air inside the packaging container 1.

In the packaging container 1 of the present embodiment, the flange portion 5 of the pack 2 is restricted from moving in the horizontal direction by the rib 11 of the support portion 8 of the transport box 3. In such a packaging container 1, since the fruit holding portion 4 of the pack 2 does not come into contact with the transport box 3, it is difficult for the impact during transportation to be transmitted to the fruit F.

FIG. 12 is a perspective view showing a transportation method of the packaging container 1. As shown in FIG. 12, in the transportation method of the packaging container 1 of the present embodiment, a plurality of packaging containers 1 are stacked in the vertical direction. A lid 17 is placed on the uppermost packaging container 1. Such a lid 17 maintains the inside of the uppermost packaging container 1 in an environment suitable for the fruit F (shown in FIG. 11) contained therein.

The stacked packaging containers 1 are placed on, for example, a pallet 18 and transported. In the transportation method of the present embodiment, four sets of packaging containers 1 stacked in three stages are placed on the pallet 18. In such a transportation method, since the two ventilation portions 9 of each transportation box 3 are in contact with the outside, air from the outside can be introduced into each packaging container 1.

Although the particularly preferable embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and can be modified into various embodiments.
