Since they are engaged with each other and assembled, the work efficiency cannot be sufficiently improved in each process of manufacturing and assembling. (B) The cost required for packaging increases accordingly. (C) Since the partition that combines a plurality of corrugated cardboard pieces is bulky, the cost for storage and transportation also increases. (D) If the assembled partitions are carelessly handled, the meshing points will be disengaged, and the assembled shapes will easily collapse. Therefore, an object of the present invention is to simply and quickly fold only one cushioning plate material along the fold line, to surely fold it up into a partition shape so as not to lose its shape, It is to provide a partition material for packaging that achieves a significant reduction in manufacturing / assembly costs and storage / transportation costs.

The half halves 1 and 2 on both sides of the overlapping fold A extend orthogonally from the center of each side toward the overlapping fold A and have a length that does not reach the center of the fold. A fold line B is provided. This results in halves 1 and 2
On both sides of each of the orthogonal folds B, the partitions 1a and 1b are respectively provided.
And 2a and 2b are formed (see FIG. 3).

In order to make it possible to bend along each of the folding folds A, the lengths of the overlapping folds A which do not reach the central portion of the folds along the folds, respectively, in this embodiment, Separation notches C each having a length about 1/4 of A are provided. Further, each of the separation notches C is provided with a bending cut D that extends in a direction away from each other toward the end of the orthogonal fold B. Although the folding cut D of this embodiment is provided in an L shape (see FIG. 1), it is not limited to this shape.

夫々折曲させる。Next, from the corrugated board 101, the partition 201
The procedure for folding up will be described. First, the folding crease A for polymerization is given an upward crease. After that, a pair of partition pieces 1b and 2b, which are diagonally opposed to each other on both sides of the fold A for superposition, are picked with one hand respectively, and along the orthogonal fold B as shown in FIG. Bend each upward at a slightly smaller angle than the right angle.

れる。At this time, at the end of the orthogonal fold line B, the engagement piece 3 is formed so as to be surrounded by the engagement cut line F.
Is left without being bent, and a notch d is formed at a portion corresponding to the left portion as shown in FIG.

【００１３】次いで、段ボール１０１を、図２に示した

折し終えると、両仕切片１ｂ，２ｂは縦列状に隣接して
起立された状態になる（図３参照）。Next, as shown in FIG. 2, when the corrugated board 101 is folded upward along the folding fold A, the two pieces 1b and 2b are in a state of being overlapped with each other. As the sheets are further folded, they rub against each other, and when the two pieces are completely folded, the two pieces 1b and 2b are vertically erected adjacent to each other (see FIG. 3).

中仕切２０１が簡単・迅速に折上がる。At the same time, the partitions 1a and 2a are integrally connected to the partitions 1b and 2b through the orthogonal fold line B.
Also, they are erected in a column in association with the bending operation. Thus, as shown in FIG. 3, each partition 1a, 1b, 2
The partition 201 having a desired shape, in which a and 2a are arranged in a cross shape in plan view, can be folded up easily and quickly.

行える。While the overlapping portion b plays a role of increasing the structural strength of the intermediate partition 201, when a packaged article is housed in each partition section S, the packaged article is likely to be caught in the step portion c. Therefore, the folded partition 201 is turned upside down as shown in FIG.
It is good to put it inside. In this way, each partition 1a, 1
The cross-shaped arrangement of b, 2a, and 2b is also stable, and the operation of putting the packed article in each of the four partition sections S can be performed smoothly.

高められる。The packing partitioning material may be shipped in the form of a single flat corrugated cardboard 101 with the folds and cuts provided, or by using an assembly robot or the like, once the partitioning material of the partition 201 is removed. After being folded up into a shape, it may be shipped in a flatly crushed state as shown in FIG. Either way, it can be stored and transported in an extremely compact form. And, if shipped in a crushed state, the work efficiency at the packing work site can be further improved.

As shown in FIG. 6, the packaging partitioning material of this embodiment is composed of one substantially convex corrugated cardboard (buffer sheet material) 102 having creases and cuts at required plural points. Simply fold it along the line shown in Figure 7,
The middle partition 202 including the six partition sections S can be folded up.

の形態に折上がる。The operation of folding the corrugated board 102 into the shape of the partition 202 is substantially the same as that of the first embodiment. That is, first, the folding fold A for polymerization has a crease. next,
The folding fold A for overlapping is formed by bending one set of the partition pieces 1a and 2a of the one half side (upper half side of FIG. 6) of the imaginary boundary line connecting the imaginary line G and the break H upward at right angles. First, this half side is folded up into a cross-shaped partition shape in a plan view by folding it in half.

Fold up to. As a result, as shown in FIG. 7, the partition 202 having a desired shape and having six partition sections S is formed in a form such that two cross-shaped partitions are connected side by side. Unlike the complicated folding operation, it can be folded very easily and quickly.
