Description

The present invention relates to a container for packaging and transportation which can be handled by a forklift and can be easily assembled and disassembled.

As a packing box for packing and transporting an article, a box having a bottom made of reinforced corrugated cardboard on a metal pallet has been proposed (Patent Document 1). In this packing box, an article is placed on a pallet and fixed with a band, and then a reinforced cardboard box is placed on the pallet to fix the box to the pallet. The box is fixed by a method in which a locking member having a hole is attached to the pallet, the position of the locking hole opened in the box is matched with the hole, and the locking tool is used. The pallet and the box can be separated by removing the locking tool.

From the viewpoint of ease of handling of pallets, for example, ease of stacking, it is not preferable that the above-described locking member is attached because it hinders stacking. It is desirable that the pallet surface remain flat to form a box that can be used for packaging and transporting various items. It would be even better if small items could be piled up and handled with a forklift. Even more desirable is to be able to stack more than one box of this type.

On the other hand, pallets were made of plastic-based materials and their dimensions could be adjusted within a certain range. The pallet is made of plastic, the required number of L-shaped blocks used for the corners, the T-shaped blocks used for the sides and the X-shaped blocks used for the inside, and the required number of metal or plastic shafts connecting the blocks. It is configured by combining. Each block has a shape in which the upper piece and the lower piece are connected by a connecting piece, and a hole for inserting a shaft is provided in each of the upper piece and the lower piece in two, three, or four sides. A fork can be inserted, and a structure that functions as a pallet can be created.

This plastic pallet can be adjusted to an overall multiple of the unit by using a shaft of a selected length and adjusting the overall size of the pallet, and by connecting the shaft with an increased number of blocks. There is an advantage that you can. However, it is not considered to place a box on top of it, and it is naturally not considered to stack what was put in a container with a box. Since the flatness of the bottom surface is not ensured unless a plate is laid again, it does not withstand loose stacking.
JP2002-205738

The object of the present invention is to make use of the advantages of the above-mentioned plastic pallet that the size can be adjusted, and to keep the upper surface of the pallet itself flat and to form a container with a box on the pallet. It is an object of the present invention to provide a container for packaging and transportation which makes it easier to assemble and disassemble the box, can accommodate smaller articles as needed, and can be stacked in two or more stages.

A container for packaging and transporting according to the present invention which achieves the above object and which is easy to assemble and disassemble is shown in FIG. 1 schematically and in detail in FIGS. The pallet (1) is made of plastic and has an L-shaped block (2) used for the corner, a T-shaped block (3) used for the side, and an X used for the inside. Each block is configured by combining the required number of the character blocks (4) and the required number of metal or plastic shafts (5) connecting the blocks, and each block has an upper piece (21, 31, 41) and a lower piece. (22, 32, 42) are connected by connecting pieces (23, 33, 43), and the holes (24, 34, 44) for inserting the shaft (5) into the upper piece and the lower piece are two-way and three-way. Or the structure provided on all sides The L-shaped block (2) and the T-shaped block (3) are provided with grooves (25, 35) for fitting the lower part of the side wall in parallel with the pallet outer edge of the upper piece. The side wall (7) is characterized by being a plastic cardboard or paper cardboard having a length matching the groove of the pallet.

The container for packaging and transportation according to the present invention employs a plastic pallet made of a material mainly composed of plastic, and has the advantage that its dimensions can be adjusted and is lightweight, and this pallet is made of plastic. By combining the corrugated cardboard or paper corrugated cardboard as the side wall, it can serve as a container that is not required for the pallet. This container does not have a locking member such as a known packing box on the pallet, and can be easily stacked as a pallet, not only easy to assemble and disassemble as a container, but also the pallet itself can be disassembled. Therefore, the container of the present invention, whether it is a side wall or a pallet, can be used continuously by replacing the part damaged or worn by use, and can enjoy a long life as a whole.

The three types of blocks constituting the container pallet of the present invention can be manufactured by plastic injection molding. The material must be tough but should not be expensive, so it is selected from plastics such as polypropylene and ABS resin. Plastics such as polycarbonate, nylon and polyacetal can be used if the price permits. The connecting shaft is preferably made of a tough metal, such as steel or duralumin, but it can also be made of a plastic material if it is desired that the load on the pallet be relatively small and lightweight. .

As described above, the side wall of the container of the present invention is formed by cutting plastic cardboard or paper cardboard into a length corresponding to the length of the groove provided in the pallet. “Plastic corrugated cardboard” means that a so-called plastic foam board is included in a hollow plate that has a plastic material having a corrugated paper structure or a similar structure (for example, a cross section of a harmonica type). Select from the group of highly rigid plastic hollow plates. "Plastic bubble board" is a cap sheet having a large number of cap-shaped protrusions formed by molding a melt-extruded plastic sheet, and a flat back sheet and liner sheet are pasted on the bottom and top surfaces of the cap. Is a molded product.

If the side wall is folded before the container is assembled and after the container is disassembled, it is preferable that the side wall is not bulky and is easy to store and return. An example of such a foldable sidewall is shown in FIG. When plastic corrugated cardboard is used, the bent portion of the side wall is advantageously a hinge structure. The hinge structure can also be realized by the V-cut method, but it is preferable that the hinge structure can be bent without reducing the strength of the bent portion, that is, without reducing the thickness. The method of forming is preferable.

When it is necessary to increase the buckling strength of the side wall, there is a restriction that the size and shape of the pallet allow, but the cross-sectional shape of the side wall is a shape close to a cylinder, or a shape that combines multiple polygons. This can meet this demand. This requirement is particularly strong when the containers of the present invention are used in a stack of two or more stages. The simplest example is a corner dropping square tube (octagon) as shown in FIG. 6A, but a more complicated polygonal tube with four sides as shown in FIG. 6B is also possible. These side wall cross-sectional shapes are naturally limited because the grooves corresponding to the cross-sectional shape must be carved in the block parts of the pallet in order to be supported by the pallet as a whole. A significant improvement in buckling strength can be expected. When the side wall has such an aspect, the above-described hinge structure is also useful.

As for the groove for fitting the lower part of the side wall in the L-shaped block and the T-shaped block, as shown in FIG. 7A, the simplest method is to design a plastic mold so that the groove can be formed. It can be provided by molding in the above. However, it is necessary to provide a deep groove in order to make the side wall fit into the groove sufficiently strong.

In such a case, as shown in FIG. 7B, a U-shaped side wall support (8) made of a rigid material is fixed to the upper surface of the upper piece of the L-shaped block and the T-shaped block. It is recommended that a groove be provided. A metal is suitable as the material having rigidity, but an engineering plastic can also be used. The U-shaped side wall support (8) can be fixed by melt bonding using the same kind of plastic material to a plastic L-shaped block or T-shaped block, or by screwing or bonding. You can also. Produce a shape with an anchor (not shown) at the bottom of the side wall support and insert it into an L-shaped block or T-shaped block. By doing so, the installation and fixing of the groove can be realized at the same time.

In some cases, as shown in FIG. 7C, a U-shaped side wall support (8) made of a rigid material is embedded in the upper surface of the upper piece of the L-shaped block and the T-shaped block. The upper part may be provided by being fixed in an exposed manner. This aspect has an advantage that a sufficient depth and strength for fitting the side walls are ensured, and that the side wall support protrudes slightly on the upper surface of the upper piece, and does not jam.

Of course, a lid can be used when it is necessary to cover the top of the container of the present invention. The lid is suitably a cover lid or a folded lid (both not shown), and in any case, a shape that fits with the upper portion of the side wall on the lower surface is preferable.

A convenient aspect for using the container of the present invention in a stack of two or more stages is that the groove (25 provided in the upper piece described above is provided below the lower piece of the L-shaped block and T-shaped block constituting the pallet. , 35), and steps (27, 37) are provided so that the outside is high and the inside is low, as seen in each of FIGS. By placing the upper part of the side wall of the lower container inside the step of the upper pallet, the position of the side wall becomes stable when stacked, and stacking can be easily performed.

When it is desired to supplement the flatness of the bottom of the container of the present invention, for example, when a container capable of stacking small articles as described above is configured, as shown in FIG. An inner groove (36) is provided on the inner side of the groove (35) for inserting the lower portion of the T-block) and the side wall (7) in parallel with the inner groove (36). A rectangular bottom plate (6) having 61) in the periphery may be combined with the pallet. As shown in FIG. 8, it is preferable that the periphery of the plate extends outward and reaches the inside of the side wall. This rectangular plate can also be produced with the plastic corrugated board as described above, which is advantageous.

In the aspect of using the side wall support (8) having a U-shaped cross section as shown in B and C of FIG. 7, the bottom plate (6) adopts a modified side wall support. Thereby, it can fix to a container bottom part, without depending on the protrusion (61) fitted to an inner side groove | channel. Specifically, for example, as shown in FIG. 9, the bottom plate fixing piece (81) can be extended from the side wall support (8), and the end of the bottom plate can be pressed by the bottom plate fixing piece.

As another method, as shown to A of FIG. 10, an inner side opening part (82) is provided in a side wall support body (8), and the end of a baseplate is inserted there and fixed. In this embodiment, in order to secure the strength of the inner opening (82), it is necessary to provide a connecting portion (83) as shown in FIG. It goes without saying that the portion of the bottom plate that hits the connecting portion (83) is cut out accordingly.

The containers of the present invention can be used to package and transport a wide range of articles, except when intended for packages that are not overly heavy and severely dislike impact.
