Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a box for storing, transporting, etc. a roll product formed by winding a belt-like material around a core, such as an original film.
[0002]
[Prior art]
For example, a raw film such as a resin film such as polypropylene or polystyrene, or cloth is wound around a cylindrical core (core) to form a roll, and is stored and transported. While the film itself is very delicate, the roll is so heavy that it cannot be placed directly on a flat or pallet. Therefore, when storing or transporting, the roll core is mainly fixed to a wooden frame and suspended in a suspended state and placed on a wooden or plastic pallet. And the fork of a forklift is inserted in a pallet in such a form, and the roll goods are conveyed.
[0003]
However, when these wooden frames and pallets are used, there is a problem that the efficiency of storage and transportation is poor because the member that supports the roll product and the pallet for carrying it with a forklift are separate. In addition, these wooden frames and pallets have high manufacturing costs, and it is necessary to secure a storage place for the wooden frames and pallets themselves, and it is difficult to dispose of them such as disposal and recycling.
Furthermore, since there is a risk of pests on the wooden frame and the wooden pallet, it is necessary to perform steaming or heat treatment in advance, and in recent years, export using these may be restricted.
[0004]
[Problems to be solved by the invention]
Therefore, in order to solve the above problem, in the present invention, a high-weight roll product obtained by winding a belt-like material such as a resin film around the core can be accommodated, and storage and transportation can be efficiently performed. An object of the present invention is to provide a roll product storage box that can be manufactured at a low cost and is not subject to export restrictions.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, there is provided a box for accommodating a roll product obtained by winding a strip around a winding core, each of which is made of corrugated cardboard, and is disposed opposite to the upper surface member. A bent bottom member, and the upper surface member and two supporting members disposed opposite to each other so as to be perpendicular to the bottom surface member, and both edges of the upper surface member and the bottom surface member are folded in a U-shape. Portions are fitted to the upper and lower edges of the support member via the engaging portions, respectively, and the support member supports the ends of the cores protruding from both ends of the roll product. There is provided a corrugated cardboard box for containing a roll product, characterized in that it has a notch, and the bent portion of the bottom member has a fork insertion port for carrying with a forklift.
[0006]
If it is a corrugated cardboard box for accommodating a roll product having such a structure, it is very strong in structure, and can accommodate the roll product in a suspended state in the box, and the box itself also has the function of a pallet. Therefore, it is not necessary to prepare a pallet separately, and the storage and transportation efficiency is excellent.
Further, since the entire box is made of a simple member made of cardboard, it is lightweight, easy to assemble, and can be manufactured at low cost. It can be easily recycled after use. Furthermore, since no pests are parasitized, there is no need for fumigation or heat treatment, and there is no restriction when exporting roll products.
[0007]
In this case, it is preferable that the support member is formed by stacking cardboards so that the width direction of the cardboards is vertical.
Thus, if the support member is laminated so that the width direction (longitudinal direction) of the cardboard is vertical, the strength of the support member in the vertical direction becomes very high. It can be reliably supported and accommodated, and the support member does not break. In this case, the type of cardboard used or the number of stacked sheets may be appropriately adjusted according to the weight of the roll product to be accommodated.
[0008]
Of the bent portions of the bottom surface member and the top surface member, at least the bent portion of the bottom surface member is preferably formed by laminating a corrugated cardboard whose cardboard width direction is vertical and a horizontal corrugated cardboard.
Thus, if the bent portion is formed by laminating the corrugated cardboard in which the width direction of the corrugated cardboard is vertical and the corrugated cardboard that is horizontal, high strength can be exhibited in both the vertical and horizontal directions. Since the bent portion has a fork insertion port, it is possible to prevent damage to members when transported by a forklift or when boxes are stacked.
[0009]
The support member may have a plurality of notches for supporting the end of the core.
If the support member has a plurality of notches as described above, a plurality of relatively small-diameter roll products can be accommodated together.
[0010]
Furthermore, the cardboard box of the present invention further includes a cover made of cardboard, and when the cover is covered from above the cardboard box, the lower edge of the cover is the same as the upper edge of the fork insertion opening of the bottom member, It can also be a higher position.
By providing such a cover, it is possible to prevent contamination of the roll product without causing any obstacle to transportation by a forklift.
[0011]
Further, in the present invention, it is preferable that a water-soluble resin coat is applied to at least a portion facing the outside of the top member, the bottom member, the support member, and the cover.
By applying such a water-soluble resin coat, water repellency, moisture proofing, etc. can be imparted. For example, even if it gets wet with water due to rain, the strength of the box is not impaired, and the roll product in the box is contaminated. Can be surely prevented.
[0012]
Furthermore, each member constituting the cardboard box can be made of a composite material of cardboard and plywood.
If a member made of a composite material of corrugated cardboard and plywood is used in this way, the strength becomes very high, and even a particularly heavy roll product can be safely stored and transported.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings, but the present invention is not limited thereto.
[0014]
FIG. 1 shows an example of a corrugated cardboard box for storing rolls according to the present invention, FIG. 2 shows its front side, and FIG. 3 shows its side face.
The roll product accommodating cardboard box 1 is composed of four members made of cardboard, and the upper surface member 2 and the bottom surface member 4 are arranged to face each other, and two vertical supports are provided near both ends of the upper surface member 2 and the bottom surface member 4. The member 3 is disposed opposite to the member 3. Both edges of the upper surface member 2 and the bottom surface member 4 are bent substantially vertically into a U-shape to form bent portions 6, 7. The bent portions 6, 7 are formed on the two support members 3. They are fitted through locking portions 9 at two places on the left and right of the upper edge and at two places on the left and right of the lower edge.
[0015]
Each support member 3 has a vertical cutout portion 5 from the upper edge portion to the vicinity of the center portion, and supports the respective end portions of the winding core protruding from both ends of the roll product at the lower end of the cutout portion 5. can do. Further, the bent portion 7 of the bottom member has a fork insertion port 8 for carrying with a forklift.
[0016]
Since each member is made of cardboard, the size can be easily changed according to the size and weight of the roll product to be accommodated, multiple cardboards can be stacked, and reinforced cardboard using a general reinforcing core The strength can be increased by using. In the corrugated cardboard box 1 shown in FIG. 1, a reinforced corrugated cardboard having two layers of reinforcing cores called an AB flute (W (double)), so-called A flute (thickness 5 mm) and B flute (thickness 3 mm) is used. . And in the location where especially high intensity | strength is required, it is supposed that it can endure the load of a roll goods, and the conveyance by a forklift by making it the structure which laminated | stacked several this reinforced corrugated cardboard.
[0017]
In order to reduce the thickness, especially when the cardboard box needs to have a very high strength to accommodate a heavy roll product and each member needs to be laminated with, for example, 10 or more cardboards. In addition, a composite material of cardboard and plywood can be used. For example, if a member is formed by using cardboard attached to both sides of a plywood, a very high strength can be exhibited even though the thickness is relatively small. In particular, if such a composite material is used for the portion supported by the fork, the strength of the fork insertion port portion can be increased, and transportation by a forklift can be performed safely.
[0018]
Moreover, water repellency, moisture proofing, water resistance, oil resistance, etc. can be imparted by providing a water-soluble resin coat on at least the portion of each member of the cardboard box that faces the outside. For example, a water-soluble coating agent or a water-soluble color resin exhibiting water repellency, moisture proof, water resistance, or oil resistance is applied to the corrugated cardboard liner that faces the outside of the top member 2, the support member 3, and the bottom member 4. good. If the water-soluble resin coat is applied to the outside of the box in this way, the strength of each member will not be lost even if the box absorbs moisture during long-term storage or is exposed to some rain. Further, when the roll product is weak against water or oil, contamination of the roll product can be prevented more reliably. In addition, when a color coating agent is applied, the entire surface is monochromatic, so that visibility and discrimination are excellent, and it can be used for differentiation and identification management from others utilizing the color. Needless to say, the water-soluble resin coat may be applied not only to the outside of each member but also to the inside surface.
[0019]
Examples of the water-soluble resin that can be used for the water-soluble resin coat include natural polymer compounds such as casein, albumin, and gelatin, water-soluble celluloses such as methyl cellulose, carboxymethyl cellulose, and hydroxyethyl cellulose, and polyethylene glycol, polypropylene glycol, and the like. Examples thereof include water-soluble acrylic resins such as ethers, (meth) acrylic acid polymers and acrylic-styrene copolymers, and water-soluble synthetic polymer compounds such as water-soluble polybutyral and polyvinyl alcohol. In addition, since such water-soluble resin is easily dissolved in treated water in a recycling process or the like, it is easy to recycle and no toxic substance is generated even when incinerated.
[0020]
Examples of the method for applying the water-soluble resin coating include, for example, a bar coating or roll of a solution obtained by dissolving or dispersing the above resin in water or an emulsion of these resins on a corrugated cardboard surface (corrugated cardboard liner) that is a raw material of each constituent member. A coating layer can be formed by applying by a known coating method such as coating, gravure coating, air knife coating, blade coating or the like. The thickness of the coating layer is not particularly limited, but it is usually preferable that the coating amount be about 5 to 50 g / m ^{2 in} terms of wet weight.
[0021]
A procedure for assembling the corrugated cardboard box for accommodating a roll product shown in FIG. 1 and further accommodating and transporting a roll product such as a resin film will be specifically described.
First, using a corrugated cardboard as a material, this is punched and bonded into a predetermined shape, and a top member 2, a bottom member 4, and a support member 3 as shown in FIG. It is desirable to use a corrugated cardboard material having high strength for both the liner and the core.
[0022]
In particular, since the support member 3 supports the end of the core of the roll product at the end of the notch 5, the support member 3 is required to have high strength that can withstand the weight of the roll product in the vertical direction. Thus, the above-mentioned AB flute is used as a corrugated cardboard material, and the strength can be further increased by laminating a plurality of the same. At this time, rather than stacking so that the cardboard flow direction (perpendicular to the step) is vertical, stacking so that the width direction (longitudinal direction) of the cardboard is vertical is relative to the vertical direction. Higher strength can be exhibited.
For example, as shown in FIG. 5 (A), the support member 3 is made of reinforced corrugated cardboard made of AB flute through an adhesive so that the width direction of the corrugated cardboard becomes vertical when assembled into a box. It is supposed that they are laminated.
[0023]
It is preferable that the bottom surface member 4 and the top surface member 2 have sufficient strength. In particular, when the fork of the forklift is inserted into the fork insertion port 8 and lifted at the bent portion 7 of the bottom surface member, it depends on the weight of the roll product. Load is applied. Therefore, of the bent portions 6 and 7 of the bottom surface member and the top surface member, at least the bent portion 7 of the bottom surface member is required to have a high member strength and also be resistant to bending and twisting. Therefore, as shown in FIG. 5 (B), the bent portion 7 of the bottom member is laminated with six reinforced corrugated cardboards made of AB flute so that the width direction of the corrugated cardboard is vertical, horizontal, and vertical. Has been. As a result, it can sufficiently withstand the load when it is lifted by a forklift, and the upper edge of the fork insertion port 8 is not easily deformed as it is used. What is necessary is just to adjust suitably the number of laminated | stacked cardboard materials (or thickness) in the bending part of this bottom surface member, and the height (h) of the part above the fork insertion port 8 according to the weight of the roll goods to accommodate. In this embodiment, the bent portion 6 of the top member is also formed by laminating corrugated cardboard in the same manner as the bent portion 7 of the bottom member. Thereby, it can be set as a corrugated cardboard box which is stronger and more resistant to bending and twisting.
[0024]
Among the members produced by the punching process or the like as described above, the upper surface member 2 and the bottom surface member 4 are folded at predetermined edges to form U-shaped portions 6 and 7. Then, the two support members 3 are fitted to the bent portion 7 of the bottom surface member via the locking portion 9 so as to be perpendicular to the bottom surface member 4 and are arranged to face each other.
[0025]
Next, the end portion of the core 11 protruding from both ends of the roll product is inserted from above the cutout portion 5 of the support member 3 and supported by the lower edge. Accordingly, the roll product is held by the support member 3 in a state of floating on the bottom member 4. Then, the support member 3 is fixed even at the upper part by fitting the bent portion 6 of the upper surface member to the left and right of the upper edge of each support member 3, respectively, and the entire box is resistant to torsion and vibration. It becomes a structure. By such a procedure, the roll product 10 is stably accommodated in the box 1 in the state shown in FIG.
[0026]
And the cardboard box 1 for roll goods accommodation of this invention accommodates the roll goods 10 in the state suspended in the box 1, and since the box itself has the function of a pallet, it uses a separate pallet. It can be transported directly with a forklift without. That is, as shown in FIG. 7, the fork 12 of the forklift can be inserted into the fork insertion port 8 of the bottom surface member 4 and lifted for transport.
[0027]
The corrugated cardboard box for accommodating rolls according to the present invention may be provided with a cover made of cardboard. FIG. 8 shows a state in which the cover 13 is covered from the top of the cardboard box. This cover is a corrugated cardboard box generally referred to as a semi-A type and having no bottom flap, and the lower edge of the cover 13 is slightly higher than the upper edge of the fork insertion port 8 of the bottom member 4. In addition, you may use what the lower edge of the cover 13 becomes the same position as the upper edge of the fork insertion port 8 of a box.
[0028]
For example, when the roll product needs to have a light-shielding property or needs to prevent contamination, the roll product is covered almost entirely with cardboard to prevent contamination and the like. it can. Further, since the fork insertion port 8 is not blocked, the forklift can be transported with the cover 13 covered. In addition, when stacking with such a cover, the load is mainly received by the support member. Therefore, it is not necessary to give the cover a load resistance, and the general-purpose product as described above can be used. Can be offered at.
[0029]
Such a cover also preferably has water resistance and the like. For example, a cover provided with a water-soluble resin coat as described above on at least a portion facing the outside can be used. Thereby, it can prevent more reliably that the accommodated roll goods become dirty with rain etc. In addition, it is possible to use a water-soluble color resin coat that is applied to the entire surface in a single color. Thereby, visibility and discrimination are excellent, and it can be used for differentiation and discrimination management from others using the color.
[0030]
In addition, this invention is not limited to the said embodiment. The above embodiment is merely an example, and the present invention has the same configuration as that of the technical idea described in the claims of the present invention, and any device that exhibits the same function and effect is the present invention. It is included in the technical scope of the invention.
[0031]
For example, the size of the corrugated cardboard box for accommodating a roll product of the present invention and the strength of each member may be designed according to the size and weight of the roll product to be accommodated, and the support member 3 may be the end of the core of the roll product. It is good also as what has two or more notch parts for supporting a part. For example, as shown in FIG. 9, if each support member 3a has three notches 5a, three relatively small-diameter rolls can be accommodated in one box, and can be stored and stored. Transport can be performed more efficiently.
[0032]
Moreover, the material of the roll product accommodated in the corrugated cardboard box for accommodating the roll product of the present invention is not particularly limited. In addition to various resin films, paper, cloth, thin metal, etc. are wound around the core and rolled. If it becomes goods, it can accommodate without limitation.
[0033]
