JP 2012-096819 A

The packaging material 10 described in Patent Document 1 has a long side upper surface covering piece 11b, a long side lower surface covering piece 11c, a short side upper surface covering piece 12b, and a short side lower surface covering piece 12c all having a rectangular shape in plan view. At the four corners of the object upper surface 1c, the long side upper surface covering piece 11b and the short side upper surface covering piece 12b are overlapped, and a gap 15 corresponding to the overlapped thickness (t) is generated. Similarly, the long side lower surface covering piece 11c and the short side lower surface covering piece 12c overlap each other at the four corners of the lower surface 1d to be packed, and a gap 16 corresponding to the overlapping thickness (t) is generated.

When the packaging body 20 in such a state is deposited, as shown in FIG. 9, at the four corners of the top surface 1c of the object to be packed, the long side top surface covering piece 11b and the short side top surface covering piece 12b of the lower packaging body 20A And the gap 16 caused by the overlap of the long side lower surface covering piece 11c and the short side lower surface covering piece 12c of the upper packaging body 20B are vertically aligned to form a step corresponding to twice the thickness (2t). Become. When a large number of packings are deposited in this way, there is a problem that a level difference amplified by the number of depositions occurs, and the central part is bent by its own weight. In particular, if the item to be packed is a long plate material (or a laminate thereof) such as a flooring material, the center part in the length direction of the long material is easily bent when the package is deposited, As a result, the plate material is easily wrinkled with a concave warp, making the construction work difficult and reducing the commercial value.

Therefore, the problem to be solved by the present invention is to reduce a gap or a step due to overlapping of the covering pieces of the packing material at the four corners of the upper surface of the packaged object, and the packaged object is bent when the package is deposited. It is to prevent the wrinkle of the concave warp from sticking.

In order to solve this problem, the present invention according to claim 1 is a packing material for packing a substantially rectangular parallelepiped packaged article, and has a pair of long side covering portions and a pair of short side covering portions, Each long side covering portion is a long side side covering piece that covers the long side surface of the object to be packed and a length that covers each part of the upper and lower surfaces by folding back from the long side surface covering piece along the upper and lower surfaces of the object to be packed. It consists of a side upper surface covering piece and a long side lower surface covering piece, and each short side covering portion is provided on the upper and lower surfaces of the object to be packed from the short side surface covering piece covering the short side surface of the object to be packed and the short side surface covering piece. A short side upper surface covering piece and a short side lower surface covering piece that are folded back along and covering each part of the upper and lower surfaces, the long side upper surface covering piece and the short side upper surface covering piece along the upper surface of the package When folded, it is formed so that the edges are substantially in contact with each other without overlapping at the four corners of the upper surface of the packaged item. And wherein the door.

The present invention according to claim 3 is the packing material according to claim 1, wherein the long side upper surface covering piece has substantially the same length as the long side of the object to be packed and the short side upper surface covering piece is the object to be packed. The short side upper side covering piece has a length shorter than the short side of the object to be packed by the folded length of the long side upper surface covering piece on both sides of the short side, or the short side upper surface covering piece is substantially the same length as the short side of the object to be packed And the long side upper surface covering piece has a length shorter than the long side of the object to be packed by the folded length of the short side upper surface covering piece on both long sides of the object to be packed.

The present invention according to claim 4 is the packaging material according to any one of claims 1 to 3, wherein the long side lower surface covering piece and the short side lower surface covering piece are folded back along the lower surface of the article to be packed. It is characterized in that they are formed so as to overlap each other at the four corners on the lower surface of the object to be packed.

According to the present invention, when packing an object to be packed with a packing material, the covering pieces of the packing material do not overlap each other at the corners of the four corners on the upper surface of the object to be packed. As in the prior art described in Patent Document 1, a large step does not occur. Therefore, it can suppress that the center part of a package body bends with dead weight, and can prevent thru | or suppress that the to-be-packaged goods, such as a board | plate material, gets a wrinkle of a concave curvature.

The packaging material according to the present invention is particularly suitable for packaging in a state in which a plurality of plate materials such as floor materials are laminated.

It is a perspective view which shows the packing body which packed the board | plate material (floor material) laminated body with the packing material by one Embodiment (Example 1) of this invention. It is a fragmentary top view which shows the one end part of the length direction of this package. It is AA sectional drawing in FIG. It is AA sectional drawing of the state which accumulated this package. It is the same partial top view as FIG. 3 of the package which packed the board | plate material (floor material) laminated body with the packaging material by other embodiment (Example 2) of this invention (a binding band is abbreviate | omitting illustration). It is the same partial top view as FIG. 3 of the package which packed the board | plate material (floor material) laminated body with the packaging material by other embodiment (Example 3) of this invention (a binding band is abbreviate | omitting illustration). It is a perspective view similar to FIG. 1 which shows the package body which packed the board | plate material (floor material) laminated body with the packaging material by a prior art. It is sectional drawing similar to FIG. 3 of this package. It is sectional drawing similar to FIG. 4 of the state which accumulated this package.

Hereinafter, with reference to the accompanying drawings, a packing material according to some embodiments of the present invention and a packing material in which a plate material (floor material) laminated body in which a plurality of plate materials (floor materials) are stacked with the packing material will be described. To do. In these drawings, parts, elements, members and the like that are the same as or correspond to those of the packing material and the packing body (FIGS. 7 to 9) according to the prior art described in Patent Document 1 are denoted by the same reference numerals.

The packaging material 10 of the embodiment (Example 1) shown in FIGS. 1 to 4 has substantially the same configuration as the packaging material 10 according to the prior art described in Patent Document 1, and includes a pair of long side covering portions 11. , 11 and a pair of short side covering portions 12, 12. Each long side covering portion 11 includes a long side surface covering piece 11a that covers a side surface of a long side 1a (not shown in FIG. 3) of the article to be packed (a laminate of the plate materials 1), and a long side surface covering piece 11a. It consists of a long side upper surface covering piece 11b and a long side lower surface covering piece 11c which are folded back along the upper and lower surfaces 1c, 1d of the package to cover each part of the upper and lower surfaces 1c, 1d. Each short side covering part 12 is folded back along the upper and lower surfaces 1c and 1d of the object to be packed from the short side surface covering piece 12a covering the short side 1b side surface of the object to be packed, and the upper and lower surfaces. The short side upper surface covering piece 12b and the short side lower surface covering piece 12c covering a part of Each of the long side upper surface covering piece 11b and the short side upper surface covering piece 12b only covers a part of the upper surface 1c of the object to be packed, and the upper surface 1c (or the uppermost surface of the object to be packed) is formed on the open portion 13 formed therebetween. The protective sheet placed on the upper plate 1 is exposed. Although not shown in the drawing, the same applies to the lower surface 1d of the object to be packed. Several places are bound with the binding band 14 in the state packed with the packing material 10, and the package 20 shown in FIGS. 1-3 is obtained.

In the packaging material 10 according to this embodiment, the long side upper surface covering piece 11b and the short side upper surface covering piece 12b are both cut at an angle of about 45 degrees at both ends in the length direction and have a trapezoidal shape in plan view. Therefore, when these are folded back along the upper surface 1c of the article to be packed, they are in a state of being substantially in contact with each other without overlapping at the four corners. For this reason, the gap 15 as in the case of the prior art described in Patent Document 1 is not formed, and the level difference generated when the packing bodies 20A and 20B are deposited is reduced, and the amount of flexure of the packing body is reduced. The plate material 1 is less likely to have a concave warp.

In addition, since the long side lower surface covering piece 11c and the short side lower surface covering piece 12c are not cut at both ends in the length direction and extend substantially the same length as the long side and the short side of the object to be packed, On the lower surface, these end faces overlap at the four corners. This prevents the packed plate material 1 from falling off the lower surface of the packing material 10. Therefore, in the four corners of the lower surface of the packing body 20, gaps 16 are generated due to the overlapping of the covering pieces 11c, 12c. However, according to the prior art described in Patent Document 1, in the upper four corners of the lower packing body 20A. A gap corresponding to the thickness (2t) of two covering pieces (FIG. 9) is generated between the gap 15 generated and the gap 16 generated at the four corners of the lower surface of the upper package 20A (FIG. 9). Since no gaps are generated at the four corners of the upper surface of the packaging body 20A, it is possible to stop at a step corresponding to the thickness (t) of one covering piece by the gaps 16 generated at the four corners of the lower surface of the upper packaging body 20A. The bending amount of the board | plate material 1 becomes small, and it can make it difficult to get a wrinkle of a concave curvature.

In the packaging material 10 of Example 1, the long side upper surface covering piece 11b and the short side upper surface covering piece 12b are cut at an angle of about 45 degrees at both ends in the length direction, and are formed to have a trapezoidal shape in plan view. Instead of this, in this embodiment, as shown in FIG. 5, the long side upper surface covering piece 11b is formed so as to have substantially the same length (La) as the long side of the article to be packed, and the short side The upper surface covering piece 12b is formed so as to have a length shorter than the short side of the object to be packed by the folding length (Lb × 2) of the long side upper surface covering piece on both short sides of the object to be packed.

Also in this embodiment, when the long side upper surface covering piece 11b and the short side upper surface covering piece 12b are folded back along the upper surface 1c of the object to be packed, these edges do not overlap at the four corners, and the edges are substantially the same. Since they are in contact with each other, the level difference generated when the packing bodies 20A and 20B are deposited is reduced, and the amount of flexure of the packing body is reduced. It is demonstrated in the same way.

In this embodiment, as shown in FIG. 6, the short side upper surface covering piece 12b has substantially the same length as the short side of the object to be packed, and the long side upper surface covering piece 11b is on both sides of the long side of the object to be packed. The short side upper surface covering piece is formed so as to have a length shorter than the long side (La) of the object to be packed by the folding length (Lc × 2).

Also in this embodiment, when the long side upper surface covering piece 11b and the short side upper surface covering piece 12b are folded back along the upper surface 1c of the object to be packed, these edges do not overlap at the four corners, and the edges are substantially the same. Since they are in contact with each other, the level difference generated when the packing bodies 20A and 20B are deposited is reduced, and the amount of flexure of the packing body is reduced. It is demonstrated in the same way.

Although the present invention has been described in detail with reference to the examples, the present invention is not limited to this, and can be implemented with various changes or modifications within the scope of the invention described in the claims. is there. The article to be packed to be packed with the packing material 10 is not limited to a plate laminated body in which a plurality of plate materials such as floor boards as described in the embodiment are laminated, and may be a single one as long as it has a substantially rectangular shape in plan view. It does not ask | require that it is a several laminated body.
