Description

[Detailed explanation of the idea] [Industrial application field]

The present invention mainly relates to a packaging case that is housed in a container and used for transporting various articles.

[Conventional technology]

Conventionally, packaging cases made of cardboard or the like that are housed in containers and used to transport various items have been designed to be of a predetermined size, such as vertical or vertical, in order to effectively utilize the space inside the container.
Width and height 750-2300mm, preferably 1100x1100
The containers are made to a size of 1100 mm and are stored in multiple tiers, but regular wood pallets are used each time to load and unload the containers. loading site,
Pallets were also required at the loading and unloading site. However, each time loading and unloading requires manual labor, the pallets may have moisture attached to them, and if the case is made of cardboard, the moisture can weaken the case. This can cause damage to the packaging. In addition, it may be possible if pallets are provided at the loading and unloading site, but if pallets are not provided, heavy packages must be loaded and unloaded manually each time. It was impossible. Therefore, it was necessary to carry the necessary pallets.

[Problem that the invention attempts to solve]

The present invention focuses on the above-mentioned actual situation, and aims to solve the problem by improving the bottom structure of the packaging case.

[Means to solve the problem]

That is, the features of the present invention that solve the above problems are as follows:
A pallet can be held by folding the bottom component into the bottom of a transport packaging case that can be folded and assembled and has two side pieces and a foldable bottom component that extends downward from the bottom sides of the side pieces. In a packaging case with a pallet integrally provided, the bottom folding lines of the two opposing sides of the bottom component piece are positioned below the folding lines of the other two sides by the height of the pallet, and the upper folding line is positioned below the folding line of the other two sides. Fold the two sides together, place the pallet on the bottom side, fold the remaining two sides along the lower folding line, and fold the other two opposing bottom pieces with the two opposing sides of the pallet exposed. The reason is that the pallets are held together and integrated by folding. Here, the packaging case stored in the container is usually made of cardboard, and typically has four side pieces and a foldable bottom component that extends downward from each bottom side of the side pieces. The pallet can be folded and assembled freely, and holding the pallet at the bottom can be achieved by shifting the folding position of the bottom component downward. In this case, the bottom component pieces whose folding position is shifted downward need only be two of the four faces that face each other. The distance by which the fold line is shifted downward is a distance commensurate with the height of the pallet. On the other hand, the pallet that is held and integrated into the packaging case can be made of various materials such as wood, metal, and synthetic resin, but the most suitable one is made of cardboard. The pallet base plate is held by spacers and, like the structure of a normal pallet, fork insertion holes are provided so that one-way or two-way forks can be inserted thereinto. In this case, in the cardboard pallet, since cardboard has directional strength, the spacing pieces are arranged in the direction of the ridges of the cardboard. In addition, in contrast to the basic form described above, the packaging case of the present invention is usually provided with a lid on the upper opening, and further has a side piece that makes it easy to store items in the case and take out items from the case. Various modifications are possible, such as providing a storage and take-out section for items. When attaching the lid, it is convenient to appropriately provide a member for receiving the lid on the outer surface of one of the side surfaces. Furthermore, if the case is made of cardboard, it is also a preferable embodiment to apply waterproofing to the cardboard.

[Effect]

Thus, when the packaging case constructed as described above is used, a fork is inserted into the pallet at the bottom of the packaging case and the pallets are loaded and unloaded into the container, just like a conventional pallet.
It is not necessary to use a separate pallet for each pallet and to load the packaging cases containing the goods thereon, and since the packaging case itself has a pallet, it is easy to load and unload the packaged goods easily and efficiently. be able to. Note that when using a foldable and assembleable cardboard case, the case can be folded and held when not in use, and when used, the pallet can be held by the bottom component and assembled for use.

【Example】

Hereinafter, embodiments of the packaging case of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing one example of a packaging case according to the present invention. In the figure, 1 is a transport case main body of an appropriate size to be stored in a container, 4 is an upper lid, and 5 is a pallet. Each of these is made of cardboard, fiberboard, or the like, and a case body 1 is assembled with a side piece 2 and a bottom piece 3. In the case structure described above, the case body 1 is constructed by folding the side pieces 2a to 2d and the bottom component pieces 3a to 3d into each of the four side pieces along predetermined folding lines A to D, as shown in the exploded view in FIG. Therefore, it is assembled into a box, but as shown in Fig. 2, the folding lines are at different levels, and on the two opposing sides, the folding lines of the bottom component pieces 3b and 3d are the same as the folding lines of the other two sides 3a and 3c. It is located below by an amount approximately corresponding to the height of the pallet 5, and the cuts a, b,
From the point where c is the same depth, the bottom component piece 3a
3d, there is a gap between the bottom formed by the pair of mutually opposing bottom forming pieces 3a and 3c and the bottom formed by the abutment of the other pair of mutually opposing bottom forming pieces 3d and 3d. A void is formed for holding the pallet 5. Therefore, first, after folding the bottom component pieces 3a and 3c to be folded into the inner side to form a temporary bottom surface,
The pallet 5 is placed in the lower part of the pallet 5, and then the bottom component pieces 3b and 3d, which are folded in toward the outside, are folded into the lower part of the pallet 5 and fastened flat with a stitcher or the like to form a packaging case body. The packaging case shown in FIG. 3 is obtained by fitting the lid 4 onto the upper part of the packaging case main body as required. In addition, 9 in the figure is a receiving member when the lid 4 is fitted, and also plays the role of reinforcing the case body 1 at the same time. In the above-mentioned packaging case, the pallet 5 generally has an upper and lower pallet base plate 6,
6', and a plurality of intervals which are interposed between both pallet base plates 6, 6', maintain the distance between both pallet base plates 6, 6', maintain strength, and form fork insertion holes 8. It is composed of pieces 7, and when made of cardboard, the spacing pieces 7 are interposed with the ridge direction of the cardboard facing up and down, taking advantage of the directional characteristics of the cardboard. Although this pallet 5 is only provided with fork insertion holes 8 facing in one direction in FIGS. 1 and 3, it is also possible to use a pallet with fork insertion holes that intersect in a cross shape. . Fig. 4 shows yet another embodiment of the packaging case of the present invention, whereas the case described above is surrounded by four side pieces to form the case body, it is difficult to store and take out articles within the case. For convenience, a storage/retrieval portion 11 is provided on one side of the side piece. Therefore, one side of the side piece is formed so that it can be folded back from the middle, and when necessary, it can be folded back to store and take out items, and when items are stored, the folded back can be returned to its original shape and used as a normal case structure. can do. In this case, since the side piece is folded back from the middle, it is preferable that the member 9' for receiving the lid be arranged parallel to the upper side, rather than in the vertical direction as shown. The above are limited examples of the packaging case of the present invention, and it goes without saying that the present invention can be further modified in various ways without departing from its purpose. In each of these embodiments, a pallet is integrally provided at the bottom of the packaging case, and by inserting a fork into the pallet at any time to support and convey the packaging case, loading into a container or unloading from the container is possible. Loading and unloading is facilitated, and transportation can be facilitated without using separate wooden pallets as in the past.

[Effect of the idea]

As described above, in the present invention, the pallet is integrally held at the bottom of the packaging case, so the fork can be directly inserted into the through hole of the pallet part to open the container without using a separate pallet as in the conventional case. Loading and unloading can be carried out inside the container, thus eliminating the need to carry wooden or other pallets one by one during transport, making transport work extremely simple, and the pallets being held by the bottom component. The bottom of the packaging case itself has been strengthened, and since it looks almost the same as a packaging case, it has no effect on storage in a container, making it extremely practical as a completely new way of thinking about conventional transportation cases. It is true. In addition, since the pallets of this invention are exposed on both sides, there is no need to drill holes in the case, which not only does not weaken the case, but also makes it extremely easy to insert forks, etc. can be inserted securely,
Furthermore, since the pallets are firmly held at the top and bottom by the upper and lower folding surfaces, the pallets are held extremely stably. In addition, the inside of the article storage area of the case is blocked from the pallet held at the bottom of the case, which is open to the outside air, by a bottom component piece that is also folded in and abutted on the top surface of the pallet, which prevents dust and dirt during cargo handling. Items can be stored safely and hygienically without the intrusion of foreign substances such as insects or moisture absorption. Furthermore, by making the packaging case of the present invention especially made of cardboard so that it can be folded and assembled freely, and by making the pallet also of cardboard, it is lightweight, and by applying waterproofing treatment to it, waterproofness can be easily ensured. Another advantage is that when not in use, the packaging case body can be folded up like a conventional cardboard case, making it convenient to carry.
