Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a material used for protecting a product by bending a thick plate material and applying it to a corner of the product.

[0002]

[Prior art]

 In order to protect articles contained in boxes, cases, etc., protective materials are applied around the articles.

[0003] If the protective material made of corrugated cardboard is delivered as a flat plate, an operation of assembling it three-dimensionally on the user side is required, and the assembled product has a fixed shape, so that strength and thickness are not free. Also, in the case of a protective material to which a corrugated cardboard is attached, there is a problem that it is naturally thicker than a flat plate and bulky. In addition, when a corrugated cardboard is bent to be used as a protective material, there is a drawback that a force is required to bend and a repulsive force is activated during use.

[0004]

[Problems to be solved by the invention]

 The present invention has been made in view of the above points, and its problem is to protect a material which is not bulky while being kept on a flat plate during transportation or storage, is easily bent at the time of use, and does not return due to repulsive force. To provide lumber.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention provides a bent portion for bending a thick plate, a punched portion from which the material is removed, leaving a thin portion for connection, and a concave portion which meshes with the thin portion when bent. And convex portions are formed on the thick portions on both sides of the die-cut portion.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The article protecting material according to the present invention is used to bend a thick plate material and apply it to a corner of an article to protect the article. One type of packing or stuffing, characterized by being arranged especially at the corners.

As the thick board material, cardboard, a cardboard such as a corrugated cardboard core, a styrene foam board, and the like, which are laminated with a material having a thickness and a structure suitable for protection of articles, are suitable. By applying such a thick plate material to the corners, that is, the four corners, of an article stored in a box or a case, the article can be fixed so as not to move and can be protected from external force. Also, the amount of packaging material is saved because it does not have to be applied all around the article.

[0008] At the bent portion for bending the thick plate material, the material is removed, leaving a thin portion for connection, and a die-cut portion is provided. The die-cut portion is formed to facilitate bending of a thick-walled material, and is located on the side that becomes the inner surface during bending. In this state, as shown in FIG. 5, the thin portion 11 functions as a so-called hinge for connecting the thick portions 12 and 13 on both sides of the bent portion. The die-cut portion 14 is a necessary condition for facilitating bending, and may be left after the bending (FIG. 5A) or not (FIG. 5B).

[0009] A concave portion and a convex portion that mesh with each other when bent at the thin portion are formed in the die-cut portion. By forming the concave portion and the convex portion at the ends of the thick portion on both sides of the bent portion facing the die-cut portion, an uneven fitting state is created, and the bent portion is fixed. .

[0010] By forming the engagement means including the concave portion and the convex portion, the material for protecting an article of the present invention can be easily bent, and also maintains the bent shape even after releasing the hand after bending. For this reason, it is necessary to maintain the bent state by bonding or the like in FIGS. 5 (a) and 5 (b), whereas when the engagement means is provided, assembly is easy. In addition, packing work becomes easier and workability is improved.

【Example】

 More specifically, with reference to the illustrated embodiment, the example thick plate 10 is formed of a cardboard laminate. The outermost one of the corrugated boards is left as a thin portion 11 and meshes with the thick portions 12 and 13 on both sides of the punched portion 14 from which the material has been removed when the thin portion 11 is bent. A concave portion 15 and a convex portion 16 are formed.

[0012] At least one set is required for the engagement means 17 including the concave portion 15 and the convex portion 16. In the illustrated example, the concave portion 15 and the convex portion 16 having a substantially rectangular wave shape in front are engaged with each other so that the concave portion 15 of one thick portion 12 becomes the convex portion 16 of the other thick portion 13. Means 17 are formed.

The rectangular wave-shaped concave portion 15 and convex portion 16 constituting the meshing means 17 may have right-angled corners 18 and 19, and when the thickness of the thick plate material 10 is sufficiently large, sufficient meshing is possible. Power is gained. However, when the thickness of the thick plate material 10 is relatively thin, the corner portions 18 and 19 are formed to have an acute angle, and when they are formed in a so-called dovetail joint shape, a more reliable engagement force can be obtained. .

FIG. 3A shows an example of a concave portion 15 and a convex portion 16 having a dovetail shape, and FIG. 3B shows an example of a concave portion 15 and a convex portion 16 having right-angled corners 18 and 19. In the case of the embodiment using laminated cardboard, if the thickness of the thick plate material 10 is close to 30 mm, the corners 18 and 19 are perpendicular and sufficient engaging force can be obtained. It is better to do. It should be noted that good results were obtained when the angles of the corners 18 and 19 in the case of a dovetail shape were in the range of a right angle minus one degree to several degrees.

A bending line 21 can be provided in the thin portion 11. The folding line 21 determines the position at which the material for protecting articles 20 of the present invention is bent into a square shape. The example of the bending line 21 employs a means for weakening a part of the thin portion 11 such as a so-called perforation. Therefore, the bending position is automatically determined, and when bent, the concave portion 15 and the convex portion 16 are engaged with each other, the die-cut portion 14 is filled, and the bent portion is bent at a predetermined angle such as a right angle. This is the state shown by the solid line in FIG.

The article protecting material 20 is applied to a box for packaging the article 22 and a corner of the article 22 stored in the cases 23 to fill a gap between the box and the inner surface of the case 23 at four corners. Are arranged as follows. See FIG. Until it is set at the four corners, since the article protecting material 20 maintains a predetermined bent shape by the engagement means 17, the operator only has to insert it into the gap.

[0017]

[Effect of the invention]

 Since the present invention is constructed and operates as described above, it is simply flat when transported or stored, etc. No space is required, and the concave and convex portions engage with each other by simply bending during use, and maintain a predetermined bent shape. Therefore, it is not necessary to suppress the bending back due to the repulsive force, and workability is good. For this reason, for example, a protective material made of, for example, polystyrene foam, which has been conventionally used, can be eliminated. The protection material of the present invention can be suitably used for large and small home appliances and furniture.
