Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover box for protecting articles. In detail, the present invention, for example, when storing articles such as synthetic rubber such as ethylene-propylene rubber / ethylene-propylene-diene rubber and chemicals such as petrochemicals and fertilizers such as polyethylene / polypropylene synthetic resin outdoors, BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover box suitably used for preventing (protecting) articles from being contaminated by dust or moisture and from being deteriorated or deteriorated by high temperatures or ultraviolet rays.

[0002]

2. Description of the Related Art When stocking products such as ethylene-propylene rubber, it is desirable to store them in a room such as a warehouse in order to prevent them from being contaminated, deteriorated or deteriorated. Due to their small size, too much inventory, or the desire to reduce inventory costs, they may have to be kept outdoors.

Conventionally, for example, about 40 cm (length) × about 30 c
When storing ethylene-propylene rubber or ethylene-propylene-diene rubber having a rectangular parallelepiped shape having a size of m (horizontal) × about 20 cm (height) outdoors, the rubber is wrapped in a resin film for each piece and then wrapped. Figure 1 shows what was done
In a box with pallets as shown in the above, then place these boxes of goods side by side outdoors, and finally cover the aggregate of boxes with a large area vinyl sheet called blue sheet, and then vinyl sheet Is tied with a rope. Here, the boxes may be arranged in a state of being stacked in several stages.

[0004] The box shown in FIG.
It is a box assembled by joining steel and a long object 3 made of steel with screws. Here, the side surface portion 1 and the top plate portion 2 are a hollow structure plate having a thickness of 9 mm formed of a thermoplastic resin (hereinafter, this plate is also referred to as a “thermoplastic resin hollow structure plate” or a “hollow structure plate”). The details are described later), and a part of the side surface portion 1 is a door 4 for taking in and out of articles. Here, the parallel lines in the circles attached to the side surface portion and the top plate portion in the drawing indicate the direction of the rib when a hollow structure plate having parallel ribs is used.

In the conventional storage method described above, when removing a box containing articles for shipping or adding a box containing articles for storage, unwrap the rope and turn up a vinyl sheet, and After taking out a box to be stored or adding a storage box, cover the sheet with a vinyl sheet again and tie the vinyl sheet with a rope.

[0006]

However, in this conventional storage method, every time a box containing goods is shipped or added, a rope is tied or untied, or a large area vinyl sheet is rolled or covered. Doing so is a very time-consuming task. In particular, it is not easy to work on a rainy day or windy day on a vinyl sheet; the box with the goods is covered with the vinyl sheet, but the sides 1 and 2 of the box shown in FIG. Top plate 2 and long object 3 made of steel
Fine dust and moisture enter the inside of the box through a slight gap between them, and insufficient protection against temperature rise and UV cuts makes it inadequate to prevent articles from being contaminated, deteriorated or deteriorated. Is a problem.

[0007] It is an object of the present invention to provide an article protective covering box which solves these problems.

[0008]

The ribs 23 are in a parallel positional relationship, and the ribs 33 shown in FIG. The upper plates 21 and 31 and the lower plates 22 and 32 shown in FIG.
There is no distinction between the front and the back of the hollow structure plate. The hollow structure plate is a resin plate that is lightweight, has excellent water and water resistance, excellent mechanical strength, durable weather resistance, and heat insulation, and is easily processed (cut or joined).

The hollow structure plate shown in FIG.
And can withstand a compressive force in a direction parallel to the direction of the arrow (in the direction of the arrow). For example, SUMPLY (registered trademark) manufactured by Sumika Plastics Co., Ltd. (Registered trademark) is commercially available, and hollow structural plates having various thicknesses can be obtained. The thickness of the thermoplastic resin hollow structure plate used for the side portion and the top plate portion of the cover box for article protection of the present invention is not particularly limited,
The thickness may be appropriately selected according to the size of the covering box or the like, but the thickness is generally in the range of 1.5 mm to 20 mm. When the covering box is used as shown in FIG. 3, the strength of the covering box is not so required, so that the thickness is 1.5 mm to 7 mm.
mm, preferably a thin hollow structure plate having a thickness of 2 mm to 5 mm.

From the viewpoints of the weather resistance of the cover box, the protective power of the article, and the like, a cover box made of a thermoplastic resin hollow structural plate containing a light stabilizer is preferred. Examples of the light stabilizer include a benzotriazole-based, benzophenone-based, salicylate-based, cyanoacrylate-based ultraviolet absorber, a hindered amine-based radical scavenger, and a nickel complex-based quencher, among which the radical scavenger is preferred. Used for These can be used alone or in combination of two or more. Further, it can be combined with a generally used phenol-based, thioether-based or phosphorus-based antioxidant.

The amount of these light stabilizers is appropriately determined depending on the conditions of use such as indoor use or outdoor use. Generally, the amount is 0.01 to 100 parts by weight of the thermoplastic resin. 2.0 parts by weight, preferably 0.5 to
1.5 parts by weight. Coloring black with carbon black or the like is also one of the preferable embodiments from the viewpoint of the weather resistance of the cover box, the protective power of the article, and the like. In this case, the compounding amount of the carbon black is generally the same as that of the thermoplastic resin 1.
The amount is 0.01 to 2.5 parts by weight, preferably 0.5 to 2.0 parts by weight, based on 00 parts by weight.

In manufacturing the cover box for protecting articles according to the present invention, the broken line portion of one piece as shown in FIGS. 4 and 5 must be bent, but the hollow structure plate shown in FIG. An example of a method of bending the fold along a line parallel to the direction of the rib or a line perpendicular to the direction of the rib is described below. First, as a method of bending along a line parallel to the direction of the rib, a line such as a knife or the like is cut on a line to be bent of the upper plate 21 (this line must be a line located between the ribs). (Only the upper plate is completely cut) and the remaining lower plate 22 is folded by hand or the like (Method 1, see FIG. 7); the cutting edge is U (U) on the line to be bent. By pressing the U-shaped blade, a U-shaped groove parallel to the rib is formed on the hollow structural plate,
A method of bending the groove portion by hand or the like (method-2); a heat bar (a heated rod-shaped jig for melting a portion to be bent by heat) on a line to be bent; A method of bending the portion when hot (when it is in a molten state) or cold (when it is not in a molten state) by, for example, the force of a hand or the like (method-3); Is mentioned. In the method-2, the U-shaped groove may be bent inside or outside. In method 3, when the bending is performed at the time of heating, the shape of the bent portion is fixed. However, when the bending is performed at the time of cooling, the shape of the bent portion is not fixed and is movable (flexibility; easiness of bending). Therefore, it is possible to return from the folded state to the original flat state.

Next, as a method of bending along a line perpendicular to the direction of the ribs, a groove is cut on a line to be bent with a knife or the like, and the groove is outwardly bent by force of a hand or the like ( Method-4): A method in which a heat bar is applied on a line to be bent on a hollow structure plate, and then the portion is bent, for example, by hand or the like when hot or cold (method-5). Method-4 is a method that can be bent very easily, and the bent portion is sharp and beautifully finished. Method-5 is similar to method-3, and the shape of the bent portion is fixed when the bending is performed during heating. When the bending is performed in a cold state, the shape of the bent portion is not fixed, but has flexibility (flexibility; ease of bending), so that the folded state can be returned to the original flat state.

When the cover box of the present invention is manufactured by the method 3 or the method 5 and the bent portion is to be fixed, it is preferable that the bending is performed while heating. In this case, the sheet may be bent with the side to which the heat bar is applied inward or outward, but it is preferable to bend inward from the viewpoint of the strength of the obtained molded body. Further, when it is desired to make the bent portion movable, it is preferable to perform the bending at a cold time. In this case, there is an advantage that the space before storage can be reduced because the whole before being assembled with the stapler, rivet, adhesive or the like can be folded into a flat shape by folding (FIGS. 4 and 5). .

Further, the cover box, which is one of the embodiments of the present invention, has a feature that it can be folded while maintaining the configuration in use after assembly. That is, FIG.
Indicates a book cover box and its folded state. This box can be made using a rectangular thermoplastic resin hollow structure plate as shown in FIG. When the thermoplastic resin hollow structure plate is small, it is used by adding.

The folding line 55 is engraved on each of them.

On the side plate portion 53, two base fold lines 57 of a right-angled triangular fold side 56 having the short side of the top plate portion 51 as an oblique side are engraved. A central folding line 59 extending from the intersection 58 of the two base folding lines 57 is engraved to form a trapezoidal folding piece 60 on the side plate 53 in addition to the right triangular folding piece 56. Next, in the connecting portion 54,
An oblique fold line 61 connecting the corner of the top plate portion 1 and the corner of the thermoplastic resin hollow structure plate is carved.

Further, a folding line 64 around the top plate 51 passing through the intersection 68 is formed on the side plate 53, the connecting portion 54 and the side plate 52. Next, the folding procedure will be described. First, as shown in FIG. 9, the side plate portion 52 and the side plate portion 53 are folded to one side along the folding line 55 with respect to the top plate 1. The connecting portion 54 is folded at an oblique fold line 61 and a triangular connecting portion 62
Is formed, and the triangular connection portion 62 is fixed to the side plate portion 52 with a stapler 63.
