The column (C) stands upright in contact with the inner four corners of the bottom plate (A), and has a recess for connecting the adjacent side plates (B) by fitting the vertical ends of the side plates (B). The cross-section in the horizontal direction is L-shaped.

The material of the side plate (B) is not particularly limited.
As a material, for example, a hollow structure plate having a thickness of 1.5 to 20 mm, a plywood having a thickness of 2 to 15 mm, a cardboard board having a thickness of 1 to 15 mm, a paperboard having a thickness of 1 to 5 mm, a thickness of 1 to 5 mm formed from the above thermoplastic resin A resin foam board of 2 to 10 mm may be exemplified. As an example of the resin foam plate, Sumiteller (registered trademark) manufactured by Sumitomo Chemical Co., Ltd. manufactured by a homopolymer of propylene and having an expansion ratio of, for example, 1.3 times may be mentioned. The material and thickness of the side plate (B) may be appropriately determined according to the use and size of the box of the present invention, but the material may be water-resistant and waterproof, workable, light-weight, and high-strength. From the viewpoint, a hollow structure plate molded from a thermoplastic resin is preferable. By the way, Figure 1
The side plate (B) is a hollow panel made of Sumitomo Chemical Co., Ltd., which is a hollow structural plate molded from polypropylene resin.
(Registered trademark) having a thickness of 9 mm.

FIG. 2 shows a column (C) constituting the side portion 4, and FIG. 3 shows an adjacent side plate (B) by fitting a vertical end of the side plate (B) into a concave portion 5 of the column (C). ) Is connected. The material of the column (C) is not particularly limited as long as it can be formed so as to have the concave portion 5 as shown in the figure and have a horizontal cross-sectional shape of an L-shape. Examples of the material include metals such as iron and aluminum, the above-mentioned polyolefin-based resins, polyvinyl chloride-based resins, nylon-based resins, polycarbonate-based resins, and polystyrene-based resins. The thickness of the column (C) is generally 0.5 to 3 mm when the material is metal, and generally 1 to 3 mm when the material is resin. The width W of the concave portion 5 is substantially the same as the thickness of the side plate (B), and the length L of the concave portion 5 is not particularly limited, but is generally 10 to 50 mm. The material and size of the support (C) may be appropriately determined according to the size of the box. By the way,
The column (C) of the box shown in FIG. 2 is made of aluminum having a thickness of 2 mm, and the length L of the concave portion 5 is 30 mm.

The lid (D) is used so as to cover the side surface portion 4. lid
The material, structure and size of (D) may be the same as those of the bottom plate (A). By the way, the lid in Figure 3
The material, structure and size of (D) are the same as those of the bottom plate (A), that is, 9 mm thick Sumipanel (registered trademark)
And is 100 mm high. The bottom plate (A), the side plate (B) and the lid constituting the return box of the present invention
The hollow structural plate molded from a thermoplastic resin which can be used as a preferable material of (D) is a rib 6 as illustrated in FIG.
And can withstand particularly well a compressive force in a direction parallel to the rib 6. This is a well-known material. For example, SUMPLY (registered trademark) and SUMIPANEL (registered trademark) manufactured by Sumitomo Chemical Co., Ltd., which are molded from thermoplastic polypropylene resin, are commercially available. Can be obtained. When a hollow structure plate is used as the side plate (B), a compressive force may be applied to the side plate (B) from above (for example, when returnable boxes containing articles are stacked), and as shown in FIG. Is preferably used in a direction where the direction becomes vertical.

[0014] An integrated bottom plate using a hollow structure plate (A)
When manufacturing the lid or the lid (D), the hollow structure plate must be bent in a direction parallel to the ribs or in a direction perpendicular to the ribs. The bending method and the like will be described below. In order to bend the hollow structure plate in a direction parallel to the rib, for example, a U-shaped blade is pressed on a line to be bent on the hollow structure plate so that a U-shaped blade is pressed in parallel with the rib on the hollow structure plate. ) Insert a groove and bend the groove by hand or a heat bar (a heated bar-shaped jig for melting the part to be bent by heat) on the line to be bent on the hollow structural plate. And a well-known jig), and then bend the portion with the force of a hand or the like, for example. It is convenient to perform the bending when the heat is applied (when the portion to which the heat bar is applied is in a molten state) because the shape of the bent portion is fixed.
When the bending is performed at a cold time, the shape of the bent portion is not fixed but has mobility. For example, in the bottom plate portion (A), the end portions of the adjacent bottom side plates 3 are melted by heat or an adhesive agent. Or it may be joined.

In order to fold the rib in a direction perpendicular to the rib, for example, a method in which a kerf is formed on a line to be bent on the hollow structure plate with a knife or the like, and the kerf portion can be bent by hand or the like, Alternatively, a method of applying a heat bar to a line to be bent on the hollow structure plate and then bending the portion with a force of a hand or the like may be applied. The former bending method is a method that can be bent very easily, and a method in which a bent portion is sharply and beautifully finished. In the latter bending method, for the same reason as described above, it is convenient to perform the bending while heating because the shape of the bent portion is fixed. In the case of bending at the time of cold, adjacent ends may be heat-sealed or bonded with an adhesive for the same reason as described above.

In the method of assembling (using) the returnable box according to the present invention, first, the article is placed on the bottom plate (A), and then the end of the side plate (B) in the vertical direction is recessed in the support (C). 5, the side plate (B) and the column (C) are erected on the bottom plate (A), and then the lid D is put on the side surface 4. Here, when storing or transporting the returnable box containing the articles, it is preferable to hang a string, for example, in the vertical direction of the returnable box in order to prevent troubles such as removal of the lid D. As a method of strapping, for example, a sliding material 1
A method of hanging a string in the up-down direction between the space formed by the metal and the sliding material 1 and the upper surface of the lid D is exemplified.

The method of disassembling the returnable box according to the present invention is the reverse of the above-mentioned assembling method, that is, removing the hanged string if necessary → removing the lid (D) → the side plate (B) and the support (C). This is a simple method that is performed in the following order: The disassembled parts are a flat bottom plate part (A) that is not bulky, four side plates (B) that are not bulky, four columns (C) that are not bulky, and a lid that is not bulky and flat. (D).

[0018]

The returnable box of the present invention is a bottom plate portion (A) made of a hollow thermoplastic resin plate having a flat shape that is not bulky.
And a side plate (B) which is formed from four flat thermoplastic resins having no ribs and has ribs, and which is used in a direction in which the direction of the ribs is vertical, and four columns (C) which are not bulky And a lid (D) composed of a hollow thermoplastic resin plate having a flat shape that is not bulky. Assembly and disassembly of the return box are easy. Since the total volume of simply stacking these parts together is much smaller than the volume of the return box itself assembled from these parts, the return box of the present invention can be stored at a junction point or used as a shipping place. This is extremely convenient when returning to the office.
