Description

  The present invention relates to a packaging structure, and more particularly to a packaging structure that can exhibit sufficient strength even when stacked in a plurality of stages.

  In a distribution process in which an industrial product is transported for shipment or stored in a warehouse, the product is generally handled in units of pallets so that the product can be easily transported and loaded. On the pallet, for example, one or a plurality of loads are placed in a state protected by a packaging material such as cardboard. A large amount of luggage can be transported and stored by stacking the pallets (pallet packing bodies) on which the luggage is placed in multiple stages. FIG. 10 shows an example of a box pallet. The box pallet 1 in this case has a box 5 formed by connecting a side surface 4 to a frame 3 fixed on the pallet 2 and a cover lid 6 covering the upper surface of the box 5 (non-patent). Reference 1).

  When such pallet packages are stacked, the product on the lower pallet receives a load from the upper pallet, and there is a concern that quality abnormality such as deformation and distortion may occur in the product without pressure resistance. . Therefore, the frame body 3 receives a load so that an excessive load is not applied to the loaded product even when the pallet packing bodies are stacked. The frame 3 is made of a steel material or the like so as to withstand the load from the upper pallet package when the pallet package is stacked in multiple stages.

In addition to the above configuration, there is a so-called post pallet as shown in FIGS. 11A and 11B, for example. The post pallet refers to a pallet having a support column 7. The support column 7 includes a fixed type, a detachable type, a folding type, and the like. Further, as shown in FIG.

However, the pallet packing body such as the box pallet and the post pallet is generally expensive, and is based on the premise of reuse. In addition, it is difficult to palletize a large amount of boxed products and it is difficult to discard the pallet package itself.
When stacking pallet packages in multiple stages, the frames 3 of the pallet packages are not necessarily stacked with their positions aligned, and a load is not necessarily applied only to the frames. Therefore, when the pallet package is loaded, the covering lid 6 which becomes the top plate of the pallet package does not have a sufficient load resistance particularly in the vertical direction. Therefore, as shown in FIG. The possibility of causing anomalies is still not wiped out.

  The present invention has been made in view of the above situation, and provides a packaging structure that has high strength and does not cause defects in the stored luggage even when stacked, and has improved disposal and recycling of material resources. The purpose is that.

Hereinafter, preferred embodiments of a packaging structure according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is an exploded perspective view of a packing structure as an example of a packing structure according to the present invention.
The packing structure 100 includes a pallet 13 as a mounting table on which industrial products 11 and the like as luggage are mounted, a plurality of outer support columns 15 erected on the outer edge of the mounting table, and outer support columns. 15 and a cap 17 as a lid supported by the upper end of 15. A center column 19 as an auxiliary support member for connecting the pallet 13 and the cap 17 is provided inside a region connecting the arrangement positions of the outer columns 15 on the pallet 13.

  The packing structure 100 further includes a tray 21 on which the product 11 is placed on the upper surface of the pallet 13, and the tray 21 is hit against the pallet 13 with an umbrella nail 23. In addition, the tray 21 and the cap 17 form a peripheral wall by folding the corners and fixing them with the adhesive tape 27. A sleeve 25 having a “U” -shaped cross section serving as a body frame is assembled to the side surface between the outer support column 15 and the product 11 disposed at the corners of the four corners.

  The center column 19 of this embodiment is a column formed in a bar shape, and is disposed at a substantially central position on the upper surface of the pallet 13. Further, the product 11 composed of a plurality of boxes is stacked so as to surround the center column 19. And each member is assembled and fixed by winding the string and tape which are not illustrated around each part. Thus, when assembling, disassembly and separation are facilitated without using an adhesive or the like.

  The outer support column 15 is made of cardboard or a wooden support column, and is particularly preferably L-shaped in order to have independence. By making the outer support column 15 L-shaped, the assembly position on the packing structure 100 can be easily defined, and displacement is less likely to occur.

  In the above-described packing structure 100, since the center column 19 is erected between the tray 21 on the pallet 13 and the cap 17 and at a substantially central position of the tray 21, the packing structure 100 is stacked. In this case, even if a load due to the weight of the packing structure 100 stacked on the upper side is applied to the lower packing structure 100, the load can be distributed to the outer support column 15 and the center support column 19.

  FIG. 2 is a sectional view showing a state in which a load is applied to the packaging structure shown in FIG. As shown in this figure, the load is distributed to the outer support column 15 and the center support column 19, so that the deflection of the cap 17 is greatly suppressed, and the product 11 can be prevented from being crushed by this deflection. As a result, even when the pressure resistance of the product 11 is low, quality abnormalities such as deformation and distortion do not occur, and the number of stages in which the packing structure 100 can be stacked can be increased, and space for transportation and storage can be increased. Efficiency can be improved, and transportation and storage costs can be reduced. The cap 17 can be made of corrugated cardboard, thin plywood, resin board, or the like as it is because of the above effects, and does not require a high-strength material such as metal.

  In addition, since the packing structure 100 of this configuration does not use steel or the like as the material of the support column, it is not only lightweight, but also has high discardability and high material recyclability. Convenience becomes even more remarkable.

As a modification of the center support column 19, the following form is mentioned as an example.
FIG. 3 is a perspective view showing a modification of the center column. The center column 31 has a configuration in which flange portions 33 are integrally formed at the upper and lower ends. By providing the flange portion 33, the load applied to the cap 17 can be received on a wider surface, and the product 11 can be more safely protected from the applied load. In addition to integrally forming the flange portion 33, as shown in FIG. 4, the center column 35 and the flange portion 37 may be separated and used in combination. Furthermore, when the flange portion 37 separated is attached to the cap 17 and the tray 21 by adhesion or the like, the packing operation can be facilitated.

FIG. 5 is an explanatory view showing an example in which a plurality of center columns are provided.
The center support column 19 described above is only provided at a substantially central position on the pallet 13, but may be disposed at a plurality of positions on the pallet 13 as shown in FIG. In this case, since the load to be applied can be further dispersed, the local concentration of the load is alleviated and the load resistance is improved.

Next, a second embodiment of the packing structure according to the present invention will be described.
FIG. 6 shows an exploded perspective view of the packaging structure according to the second embodiment of the present invention. Note that the same members as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.
The packaging structure 200 of the present embodiment has the same configuration as that of the first embodiment except that the auxiliary support member is a partition plate 41 formed in a plate shape. The partition plate 41 is made of corrugated cardboard, fiberboard, or wood, and is arranged so as to bisect the product 11 at a position including the approximate center of the loaded product 11.
According to this configuration, the upper end of the partition plate 41 abuts on the cap 17 and the lower end abuts on the tray 21, so that a load to be loaded is released from the cap 17 side to the tray 21 side via the partition plate 41. . Thereby, it is possible to prevent an excessive load from being applied to the product 11. Further, since the partition plate 41 is disposed at a position including the substantially central portion of the tray 21, the distribution of the load to the packing structure 200 is equalized, and the twist and the bending moment due to the load bias are less likely to be applied.

  The partition plate 41 may have a configuration in which a plurality of partition plates 41 are provided in addition to the single-plate configuration described above. FIG. 7 shows an example in which a plurality of partition plates are arranged between products. Thus, by arranging the plurality of plate-like partition plates 41, the load to be applied is more finely distributed, and the load can be reduced as compared with the case of a single partition plate 41. Accordingly, the restriction on the strength of the partition plate 41 is relaxed, and the range of material selection can be expanded.

Next, a third embodiment of the packing structure according to the present invention will be described.
FIG. 8 is an external perspective view of a center column used in the packing structure of the present embodiment, and FIG. 9 is an explanatory diagram showing a state in which products are loaded using the center column.
The center column 51 of the present embodiment is formed integrally with the partition plate 55 radially from the column body 53, and each partition plate 55 prevents the lateral displacement of the product 11 as shown in FIG. It becomes. In addition, since the load to be applied is distributed to the column main body 53 and each partition plate 55, the strength of the packing structure is improved, and the reduction of the load resistance due to the load distribution reduces the column main body 53 and the partition plate 55. The degree of freedom of material selection is improved.

As described above in each embodiment, according to the packaging structure according to the present invention, even when stacked, the load applied to the lid is dispersed by the auxiliary support members such as the center column and the partition plate. Thus, the deflection of the lid is greatly suppressed. As a result, the baggage can be safely transported or stored without causing any trouble in the packaged product or the like.
In addition, as an auxiliary | assistant support member, the shape may be arbitrary as long as it is a member for disperse | distributing a load other than the said form.
