As shown in FIG. 1, the packing material 101 has a central area as the bottom surface 1 of the packing 201.
Two bottom folds A and A are provided in parallel on the bottom surface 1, and in the process of folding the packing 201, the bottom surface 1 has a cross section as shown in FIGS. It is designed to be bent into an inverted trapezoidal bowl. The portion indicated by 1a in the figure is the inverted trapezoidal inclined bottom surface.
[0010]
Then, one opposing side surfaces 2 and 2 of the packing 201 are connected to both ends (left and right ends in FIG. 1) via trapezoidal creases B that expand outward.
The opposing side surface 2 is provided with a fold C extending outward from each end of the two folds A provided on the bottom surface 1 and reaching the upper edge of the opposing side surface 2.
The other opposing side surfaces 3 and 3 are connected to both side edges (upper and lower ends in FIG. 1) of the bottom surface 1 via a crease D.
[0011]
Further, between each side edge of each pair of adjacent side surfaces 2 and 3 adjacent to each other, a substantially L-shaped spacer piece 4 is laid across an outward fold E.
Each spacer piece 4 is provided with an inward oblique fold F extending from each corner of the bottom surface 1 and reaching the outer edge thereof.
This oblique fold F is for folding the spacer piece 4 in two in a stacked manner as shown in FIG.

And since one opposing side surface 2 continues to the both ends of the bottom face 1 via the trapezoidal crease B, the opposing side surface 2 rising along the trapezoidal crease B has a packing 201 as shown in FIG. It is in a state of projecting in a trapezoidal plan view toward the inside.
Therefore, the packaged article 400 is effectively protected against an impact force exerted from the direction of the other opposing side wall 33 of the packaging box 300.
[0021]
Further, when closing the lid flap 31 of the packaging box 300, as shown in FIG. 7, first, one of the lid flaps 31 is folded upward with the bent piece 31a at the tip thereof being turned upward. It is made to fit in the notch location a and a provided in the upper edge part of the opposing side surfaces 2 and 2. FIG.
[0022]
Then, the leading end portion of the bent piece 31 is in a state of being just abutted against the upper surface of the packaged article 400 in a buffered manner.
Subsequently, if the remaining three lid flaps 31 are closed, as shown in FIG. 9, the above contact state is fixed, and the packaged article 400 is protected against an impact force from above.
Thus, the operation of packing the packed article 400 in a state in which the packing article 400 is securely buffered and held using the packing box 300 and the packing material 101 can be completed extremely efficiently.
[0023]
Next, FIGS. 10-13 has shown the packing material of 2nd Example.

The second difference is that the U-shaped cut 7 is formed on the inclined bottom surface 1a so as to contact the fold D so that the support piece 6 that receives and supports the load of the packing article 400 in a buffered manner is formed. There is.
[0029]
The third difference is that a strip-like auxiliary spacer piece 8 interposed between the side surface and the side wall of the packaging box 300 is connected to the upper edge of one opposing side surface 2 via a crease J. By the way.
As shown in FIG. 17, the auxiliary spacer piece 8 is provided with a plurality of creases K for bending into a substantially trapezoidal shape. In addition, it is not restricted to a trapezoid.
Thereby, the impact force exerted on the opposing side surface 2 can be effectively dispersed.
[0030]
Furthermore, the auxiliary spacer piece 8 is provided with two hooking protrusions 8a for fixing the bent shape.
In addition, the auxiliary spacer piece 8 is provided with a fold line M for superposition for reinforcing it by folding it in the width direction.
On the other hand, the opposing side surface 2 is provided with a latching hole 9 into which each latching protrusion 8a is inserted.
[0031]
The fourth difference is that the buffer protrusion 10 for interposing between the side surface and the side wall of the packaging box 300 at the upper edge of the opposite side surface 3 and serving as a buffer rib is shown in FIG. As shown in FIG. 17, a cut-and-cut line 11 for forming a cut-and-cut shape is provided.
The superposed piece 5 is provided with escape holes 12 for avoiding the protrusions of the packed article 400.
[0032]
