DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail. However, when the present invention is described with reference to the drawings, what is illustrated is merely an example of the present invention, and the present invention is limited to the illustrated one. Not something. Also, the drawings focus on drawing the present invention in an easy-to-understand manner, and the scale and the like do not always accurately reflect actual ones.

FIG. 1 is a perspective view of a preferred box of the present invention. This box is composed of a sliding member 1, a bottom portion, a side portion 2 and a lid portion 3 in this order from the bottom, but in this figure, the bottom portion is hidden by the side portion 2 and is not visible. In the box of the present invention, the bottom part and the side part are indispensable. However, joining the sliding member to the lowermost part of the box is convenient when the box is moved by a forklift or the like. Similarly, it is preferable to cover the side portion with a lid in order to prevent the article from dust and damage (scratch caused by contact with other objects, etc.). When storing or transporting articles in a box as shown, tie a string or the like from below the bottom to the top of the lid so that the bottom, sides, and lid do not come off from each other. I just need. Instead of hanging a string or the like, the side surface and the bottom and / or the lid may be joined with, for example, a stapler. In order to join the side portion and the bottom portion with a stapler, in FIG. 3 described below, the stapler may be driven from the outside of the side plate 7 forming the side portion 2 toward the bottom frame 9 forming the bottom portion 6.
To join the side and lid with a stapler,
A stapler may be driven from the outside of the lid 3 (see FIG. 2) to the tension 5 through the side surface 7. The size of the box may be appropriately determined according to the use of the box, etc. The size of the box in FIG. 2 is about 1110 mm in length and width, and about 610 mm in height.
It is.

FIG. 2 is a perspective view showing a state in which a lid is removed from the box of FIG. In this figure, a part of the pillar 4 and the tension (beam) 5, which are the parts constituting the side surface part 2, and
Part of the bottom 6 is visible. FIG. 3 is a perspective view of a state in which the box (not including a lid) of FIG. 2 is further disassembled. Side part 2
Are four side columns 4 and four columns 4 that are not joined to the side panel 7 and are placed in contact with the four inside corners of the side panel 7.
Consists of four tension members 5 located on the top, and two opposing tension members 5 are respectively joined on the two columns 4,
The bottom portion 6 includes a bottom plate 8 and a bottom frame 9 which is joined to the bottom plate 8 at the periphery of the bottom plate 8 and is located inside the side portion 2 to prevent the side portion 2 from moving in the horizontal direction.

The side plate is formed by processing a plate-like material (described later). The side plate 7 shown in FIG. 3 is composed of four plate-like objects each having a 5 mm-thick hollow structure plate (described later) formed of a thermoplastic resin. Two of the four plate-like objects (the plate members on the left side and the right front side in FIG. 3) have joint portions 11 (hereinafter, referred to as “glue margins”) to adjacent plate members. The side plate 7 is formed by joining four plate-like objects with a margin. As a method of joining the margins, a method using a stitch, a rivet, an adhesive, a metal or resin tack, or the like can be exemplified, but a method using a stitch or a rivet is preferable from the viewpoints of joining workability and firmness. 3 is a method using stitching.

With respect to the four pillars 4 and the four pillars 5 shown in FIG. 3, two of the four pillars 5 (the left and right front pillars 5 in FIG. 3) correspond to the pillar 4 and the right pillar 5, respectively. Each of the remaining two stiffeners 5 (the left stiffness 5 and the right stiffness 5 in FIG. 3) is a non-joined tension 5.
And are joined. The material of the pillars and the tension is not particularly limited, but wooden is generally used from the viewpoint of ease of processing and joining. The material of the support 4 and the tension 5 in FIG. 3 is wooden.

As a method of joining the support 4 and the tension 5,
A method using a stapler, a nail, an adhesive, or the like can be exemplified, but a method using a stapler is preferable from the viewpoints of joining workability and rigidity. 3 is a method using a stapler. The size of the support and the tension are not particularly limited, and may be appropriately designed according to the size of the box, the weight of the article, and the like. In the case of FIG. 3, the support is 30 mm × 60 mm × 430.
mm (length), tension is 30 mm x 60 mm x 11
00mm (length of tension not joined to the support) and 1
040 mm (the length of the tension jointed to the support).

[0014] In a side surface portion composed of a side plate, two stiffeners that are not joined to the support, and two parts consisting of the support and the stiffness joined to each other, the support and the stiffness are formed inside and at the bottom of the side plate. It only sits on top of it and is not joined to the side plate or bottom. Here, the ends of the two stiffeners that are not joined to the struts (total of four places) are, as shown in the figure in the circle of FIG. Are simply placed on the upper end (total of 4 places). The figure inside the circle also shows the side plate 7.

The bottom part comprises a bottom plate and a bottom frame joined to each other. The bottom plate 8 in FIG. 3 is made of a single wooden plate having a thickness of 18 mm, but its material and size are not particularly limited, and are appropriately determined according to the size of the box, the weight of the article, the use of the box, and the like. I just need. As a material, besides wood, a resin or metal material can be exemplified, but wood is preferred from the viewpoint of ease of production of the bottom. In addition, the bottom plate may be in the shape of a cage.

The bottom frame joined to the peripheral portion of the bottom plate is for preventing horizontal movement of the side portion placed on the bottom portion. The material and size of the bottom frame are not particularly limited, and may be appropriately determined according to the size of the box, the use of the box, and the like. As a material, besides wood, a resin or metal material can be exemplified, but wood is preferred from the viewpoint of ease of production of the bottom. The material of the bottom frame 9 in FIG. 3 is wooden, and its size is 30 mm in width × 60 mm in height × 1036 mm in length (the bottom frame 9 on the left rear side and the right front side in FIG. 3) and 1100 mm (the remaining two bottom frames) 9). As a method of joining the bottom plate and the bottom frame, a method using a nail, an adhesive, or the like can be exemplified, but a method using a nail is preferable from the viewpoint of joining workability, rigidity, and the like. The joining method in FIG. 3 is a method using nails. Note that FIG.
The reason why the upper horizontal plane of the two bottom frames 9 (the bottom left side and the right front side bottom frame 9) in the bottom 6 is higher than the upper horizontal plane of the remaining two bottom frames 9 is as follows. This is to stabilize the support placed in contact with the box so that it does not wobble, thereby increasing the stability of the side portion when the box is assembled. For this reason, the structure of the bottom frame of the box of the present invention is preferably the structure shown in FIG. 3, but the upper horizontal planes of all the bottom frames may have the same height.

Although the sliding member joined to the lower part of the bottom is not essential in the box of the present invention, the provision of the sliding member is, as described above, when the box containing the articles is moved by a forklift or the like. It is convenient. How to use the box shown in FIG. 3 (how to assemble a box containing articles) will be described. First, an article is placed on the bottom 6. Thereafter, the side plate 7 is lifted up and placed on the bottom 6 while being careful not to hit the article and damage it. Then, the two parts composed of the pillar 4 and the tension member 5 joined to each other are attached to the side plate 7. Place the remaining two tension members 5 on the support 4 while standing inside the.
Lid if necessary (not required for boxes of the present invention)
To the side surface 2.

Here, since the side plate constituting the side portion of the box of the present invention is not joined to the support or the tension,
The effort and care required to assemble the box of the present invention (care to avoid scratching the article) is lower than when the side parts, which are integrally joined together, are placed on the bottom. Less is needed. This reduction in labor and care is particularly significant in the case of a heavy side portion.

The material of the side plate constituting the side portion is not particularly limited, and may be appropriately selected according to the size and use of the box. As a raw material, for example, when a plate-like object is bent to provide a glue margin as shown in FIG. 3, a hollow structural plate having a thickness of 1.5 to 20 mm molded from a thermoplastic resin and a thickness of 3 to 15 mm
Paper cardboard board, 1-5mm thick paperboard, 2-1 thickness
A 0 mm resin foam plate or resin plate may be used. In addition, as a material in the case where the adhesive margin by bending is not provided, a plywood or a wooden plate having a thickness of 2 to 15 mm can be exemplified in addition to the above-described materials.

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 size of the side plate may be appropriately determined according to the use and size of the box of the present invention. As a material of the side plate according to the box of the present invention, a hollow structural plate molded from a thermoplastic resin is particularly preferable from the viewpoint of workability, light weight, water resistance, and the like. This material is a hollow structure plate having ribs 10 as illustrated in FIG. 4 and is a material well known as a lightweight and water-resistant plate-like material. In particular, the hollow structure plate of FIG.
It can withstand a compressive force in a direction parallel to the rib 10, and is, for example, a sample made from a thermoplastic polypropylene resin such as Sun Ply (registered trademark) or Sumipanel (registered trademark) manufactured by Sumitomo Chemical Co., Ltd. It is commercially available and hollow structural plates of various thicknesses can be obtained. When a hollow structure plate is used as a side plate, a compressive force may be applied to the side plate from above (for example, when boxes of articles are stacked), so that the direction of the ribs becomes vertical as shown in FIG. It is good to use it. The side plate 7 shown in FIG. 3 is made of 5 mm thick Sun Ply (registered trademark), which is a hollow structural plate manufactured by Sumitomo Chemical Co., Ltd., which is molded from a polypropylene resin.

A method of bending a side plate-like plate like the side plate 7 with a margin in FIG. 3 will be described. For the above-mentioned materials other than the hollow structure board (paper cardboard board, paperboard, resin foam board or resin board), a cut groove is formed on the line to be bent with, for example, a normal cutter knife, and the cut groove portion is formed by hand or the like. May be bent by the force of. When a hollow structure plate is used as a side plate, it must be bent in a direction parallel to the ribs or in a direction perpendicular to the ribs. A method of bending the hollow structure plate is described below.

In order to bend the hollow structure plate in a direction parallel to the ribs, a blade having a U-shaped blade is pressed on a line to be bent on the hollow structure plate so that the hollow structure plate is bent in parallel with the ribs. (U) -shaped groove is inserted, and the groove portion is bent by hand or the like, or a heat bar (a heated rod-shaped member for melting the portion to be bent by heat) is placed on the line to be bent on the hollow structural plate. After applying a jig (which is a well-known jig), the part is heated (when it is in a molten state) or cold (when it is not in a molten state), for example, by hand. May be bent by the force of. When the bending is performed at the time of heating, the shape of the bent portion is fixed, and when the bending is performed at the time of cooling, the shape of the bent portion is not fixed but has mobility (the original flat shape can be formed). The side plate 7 with the glue margin shown in FIG. 3 is obtained by being bent when heated by a method using a heat bar.

In order to bend the hollow structure plate in a direction perpendicular to the ribs, for example, a cut groove is formed on a line to be bent on the hollow structure plate with a blade such as a knife, and the cut groove portion is formed by a force of a hand or the like. A method of bending, or a method of applying a heat bar on a line to be bent on a hollow structure plate and then bending the portion at the time of hot or cold by, for example, the force of a hand or the like may be applied. The former bending method is a method that can be bent very easily and the method is a method in which a bent portion is sharply and beautifully finished. Since the thickness of the remaining portion that is not cut off is small, the strength may be disadvantageous.

The box of the present invention is not limited to the one illustrated in FIG. In particular, various aspects are possible for the side plate of the box, which will be described below. The side plate 7 in FIG. 3 is formed by joining four plate-like objects with a glue margin 11, but in addition, although not shown, one plate-like object (box) cut out from a hollow structure plate A side plate obtained by bending a plate-like material corresponding to an area obtained by adding the area of one glue margin to the area of all the side surfaces of the above at four places, and then joining with a glue margin can be exemplified. Although not shown, a side plate corresponding to an intermediate mode between the side plate and the side plate 7 in FIG. 3, that is, a side plate formed by joining two plate-like objects or a three plate-like object is used. Side plates joined together can also be exemplified.

In the manufacture of the side plate from the plate-like material, it is not essential to provide a margin for the plate-like material, and it may not be possible to provide the paste margin. For example, when manufacturing a side plate from four plywoods or wooden plates (no glue margins can be provided), adjacent plate-like objects may be joined with nails or the like. In the case of manufacturing a side plate from four resin plate-shaped objects having no paste margin, adjacent plate-shaped objects may be joined with an adhesive or the like.

When a hollow structure plate made of a thermoplastic resin is used as a material for the side plate, if the hollow structure plate is bent at a cold time, the shape of the bent portion is not fixed but has mobility (original flat plate). The side plate obtained by such a method can be folded into a flat plate without bulk. Therefore, the box of the present invention comprising such side plates is composed of side plates that can be folded and formed into a flat plate shape, non-bulky supports and firmness, and a bottom portion that is originally flat, so that the box as a whole is bulky. Such a box of the present invention is particularly useful as a returnable box for returning a used box to a shipping source or the like.

[0027]

The box of the present invention is a box having a square bottom and a side portion simply placed on the bottom, and is characterized in that the side plate constituting the side portion is not joined to the support or the tension. Due to the structure, the box can be assembled from the bottom and the side without any damage to the article and easily (with less labor), especially in the case of the heavy side, This is a box that can be disassembled into a bottom part and a side part.
