Japanese Unexamined Patent Publication No. 2012-096819

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

When the packing body 20 in such a state is deposited, as shown in FIG. 9, at the four corners of the upper surface 1c of the object to be packed, the long side upper surface covering piece 11b and the short side upper surface covering piece 12b of the lower packing body 20A are formed. The gap 15 due to the overlap of the above and the gap 16 due to the overlap between the long side lower surface covering piece 11c and the short side lower surface covering piece 12c of the upper packing body 20B are aligned vertically to form a step of twice the thickness (2t). Become. When a large number of packages are deposited in this way, there is a problem that a step amplified by the number of deposits is generated and the central portion is bent by its own weight. In particular, when the object to be packed is a long plate material (or a laminated body thereof) such as a floor material, when the packed body is deposited, the central portion in the length direction of the long material becomes large and easily bends, and the packing The plate material that is being made tends to have a habit of warping, which makes construction work difficult and reduces the commercial value.

Therefore, the problem to be solved by the present invention is to reduce the gap or step due to the overlapping of the covering pieces of the packing material at the four corners of the upper surface of the packed object, and the packed object is bent when the packed body is deposited. It is to suppress the habit of warping due to swelling.

In order to solve this problem, the present invention according to claim 1 is a packing material for packing a substantially rectangular object to be packed, and has a pair of long side covering portions and a pair of short side covering portions. Each long side covering portion is a length that covers each part of the upper and lower surfaces by folding back along the upper and lower surfaces of the packaged object from the long side side covering piece that covers the long side side surface of the packaged object and the long side side covering piece. It consists of a side upper surface covering piece and a long side lower surface covering piece, and each short side covering portion covers the short side side surface of the packaged object and the short side side surface covering piece and the short side side surface covering piece to the upper and lower surfaces of the packaged object. In a composition consisting of a short-sided upper surface covering piece and a short-sided lower surface covering piece that are folded back along and cover each part of the upper and lower surfaces, the long side upper surface covering piece and the short side upper surface covering piece are placed along the upper surface of the packaged object. When folded back, the four corners of the upper surface of the packaged object are formed so that the edges are substantially in contact with each other without overlapping , and the long side lower surface covering piece and the short side lower surface covering piece are folded back along the lower surface of the packed object. when the features a Rukoto formed such that they overlap with object to be packed lower surface of the corner portion.

The present invention according to claim 2 is the packing material according to claim 1, wherein both the long side upper surface covering piece and the short side upper surface covering piece have a plan view trapezoidal shape.

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 packed object. Has a length shorter than the short side of the packaged object 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 has substantially the same length as the short side of the packaged object. The long side upper surface covering piece has a length shorter than the long side of the packed object by the folded length of the short side upper surface covering piece on both sides of the long side of the packaged object.

According to the present invention, when the object to be packed is packed with the packing material, the covering pieces of the packing material do not overlap each other at the four corners of the upper surface of the object to be packed. There is no large step as in the conventional technique described. Therefore, it is possible to prevent the central portion of the package from bending due to its own weight, prevent or suppress the tendency of the packaged object such as a plate material to warp , and at the four corners of the lower surface of the packaged object. Since the covering pieces of the packing material are overlapped with each other, it is possible to prevent the packaged object from falling off.

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

It is a partial plan view similar to FIG. 3 of the packing body in which the board material (floor material) laminate is packed with the packing material according to another embodiment (Example 3) of the present invention (the binding band is not shown). It is the same perspective view as FIG. 1 which shows the packing body which packed the board material (floor material) laminated body with the packing material by the prior art. It is a cross-sectional view similar to FIG. 3 of this package body. It is a cross-sectional view similar to FIG. 4 in the state where this package body is piled up.

Hereinafter, with reference to the attached drawings, a packing material according to some embodiments of the present invention and a packing body in which a plate material (floor material) laminate in which a plurality of plate materials (floor materials) are laminated with the packing material are described. To do. In these figures, the same reference numerals are given to parts, elements, members, etc. that are the same as or correspond to the packing materials and packing bodies (FIGS. 7 to 9) according to the prior art described in Patent Document 1.

The packing material 10 of the embodiment (Example 1) shown in FIGS. 1 to 4 has substantially the same configuration as the packing material 10 according to the prior art described in Patent Document 1, and has 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 is covered from the long side side covering piece 11a that covers the long side 1a (not shown in FIG. 3) side surface of the packaged object (laminated body of the plate material 1) and the long side side covering piece 11a. It is composed 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 and 1d of the package to cover each part of the upper and lower surfaces 1c and 1d. Each short side covering portion 12 is formed by folding back the short side side covering piece 12a that covers the side surface of the short side 1b of the packaged object and the short side side covering piece 12a along the upper and lower surfaces 1c and 1d of the packaged object. It is composed of a short side upper surface covering piece 12b and a short side lower surface covering piece 12c that cover a part of the above. Both the long side upper surface covering piece 11b and the short side upper surface covering piece 12b cover only a part of the packed object upper surface 1c, and the open portion 13 formed between them covers the packed object upper surface 1c (or the most). The protective sheet) covered on the upper plate material 1 is exposed. Although not shown, the same applies to the lower surface 1d of the object to be packed. The packing body 20 shown in FIGS. 1 to 3 is obtained by binding several places with a binding band 14 in a state of being packed with the packing material 10.

In the packing material 10 according to this embodiment, both 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 have a plan view trapezoidal shape. They are formed, and therefore, when they are folded back along the upper surface 1c of the object to be packed, they do not overlap at the four corners, and their end edges are substantially in contact with each other. Therefore, the gap 15 as in the case of the prior art described in Patent Document 1 is not formed, the step generated when the packing bodies 20A and 20B are deposited is reduced, and the amount of bending of the packing body is reduced, so that the packing body is packed. It becomes difficult for the plate material 1 to have a habit of warping.

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 are extended by substantially the same length as the long side and the short side of the object to be packed, respectively, the packing body 20 On the lower surface, these end faces overlap each other at the four corners. As a result, the packed plate material 1 is prevented from falling off from the lower surface of the packing material 10. Therefore, at 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 and 12c, but according to the prior art described in Patent Document 1, the four corners of the upper surface of the lower packing body 20A are formed. A step corresponding to the thickness (2t) of two covering pieces is generated between the gap 15 generated and the gap 16 formed at the four corners of the lower surface of the upper packing body 20A (FIG. 9), whereas according to the above configuration, the lower stage No gaps are formed in the upper four corners of the packing body 20A, and the steps corresponding to the thickness (t) of one covering piece due to the gaps 16 generated in the lower four corners of the upper packing body 20A can be stopped. The amount of bending of the plate material 1 is reduced, and it is possible to prevent the habit of denting and warping.

In the packing material 10 of the first embodiment, 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 plan view trapezoidal shape. 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 object 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 packed object by the folded length (Lb × 2) of the long side upper surface covering piece on both sides of the short side of the packed object.

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, they do not overlap at the four corners, and their edge edges are substantially aligned with each other. Since they are in contact with each other, the step generated when the packing bodies 20A and 20B are deposited is reduced, and the amount of bending of the packing body is reduced, so that the plate material 1 to be packed is less likely to have a habit of denting. It is exhibited 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 packed object, and the long side upper surface covering piece 11b is on both sides of the long side of the packed object. It is formed so as to have a length shorter than the long side (La) of the object to be packed by the folded length (Lc × 2) of the short side upper surface covering piece.

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, they do not overlap at the four corners, and their edge edges are substantially aligned with each other. Since they are in contact with each other, the step generated when the packing bodies 20A and 20B are deposited is reduced, and the amount of bending of the packing body is reduced, so that the plate material 1 to be packed is less likely to have a habit of denting. It is exhibited in the same way.

Although the present invention has been described in detail with reference to examples above, the present invention is not limited to this, and can be variously modified or modified within the scope of the invention described in the claims. is there. The object to be packed with the packing material 10 is not limited to a plate material laminate in which a plurality of plate materials such as floor plates are laminated as described in the examples, and is single as long as it has a substantially rectangular shape in a plan view. It does not matter whether it is a plurality of laminated bodies.
