Among these, a double-faced corrugated cardboard sheet is preferable from the viewpoints of workability, economy, durability, and the like. The direction of the ridge line of the core of the corrugated cardboard sheet is not particularly limited, but can be, for example, the direction in which the first panel and the second panel are connected (the direction perpendicular to the folding line). .

The first panel 1 and the second panel 2 are composed of main bodies 1a and 2a having substantially the same shape and having substantially the same shape, which are arranged to face each other with an article sandwiched therebetween when assembled in a packaging container, and the main bodies 1a and 2a folded back. The base flaps 1b and 2b extend from the edge on the line 11 side and the tip edges are connected via the folding line 11, and the side flaps 1c and 2c extend from the side edges on both sides of the main bodies 1a and 2a, respectively. and end flaps 1d and 2d extending from the edges of the main bodies 1a and 2a on the tip side (opposite side of the folding line 11). Also, the first panel 1 and the second panel 2 are provided with claw pieces 1e and 2e extending from both side edges of the side flaps 1c and 2c, respectively.

The uneven height H1 of the first uneven edge 15a (the height of the top of the protrusion relative to the bottom of the recess) (see FIG. 4) is preferably at least the sheet thickness, more preferably at least twice the sheet thickness. preferable. Further, the upper limit of the unevenness height H1 is preferably 6 times the sheet thickness, more preferably 5 times the sheet thickness. If the height H1 of unevenness is less than the lower limit, it may be difficult to properly engage the first uneven edge 15a and the second uneven edge 15b, which will be described later.

The lower limit of the uneven pitch P1 (uneven period) of the first uneven edge 15a is preferably 3 cm, more preferably 4 cm. On the other hand, the upper limit of the uneven pitch P1 is preferably 6 cm, more preferably 5 cm. If the uneven pitch P1 is less than the lower limit, there is a possibility that the engagement work between the first uneven edge 15a and the second uneven edge 15b will not be easy. Conversely, if the uneven pitch P1 exceeds the upper limit, the shape maintenance function of the packaging container 20 due to the engagement between the first uneven edge 15a and the second uneven edge 15b may deteriorate.

The side edge 12b and the end edge 13b of the second panel 2, which overlap the first uneven edge 15a, have a wave-like second uneven edge having recesses and protrusions alternately arranged with the recesses and protrusions of the first uneven edge 15a. 15b is provided.

As a result, the article-packing sheet 10 can easily and reliably maintain the overlapping of the first uneven edges 15a and the second uneven edges 15b in the assembled state. In addition, in the article packing sheet 10, the first uneven edge 15a and the second uneven edge 15b interfere with each other in the thickness direction of the packaging container 20, so that the packaging container 20 can be suppressed from being crushed.

(folding line)
The folding line 11 has a plurality of wavy slits 11a arranged at intervals. According to this configuration, the article-packing sheet 10 is formed by placing an article on the inner surface of the first panel 1 and then folding the second panel 2 along the folding line 11 toward the inner surface of the first panel 1 . The concave portion and the convex portion facing each other across the slit 11a of 11 can be engaged. As a result, the folded state of the folding line 11 can be maintained more stably. In addition, since the concave portion and the convex portion facing each other across the slit 11a of the folding line 11 interfere with each other in the thickness direction of the packaging container 20, crushing of the packaging container 20 can be suppressed.

The uneven height H2 (meandering width of the slit 11a) (see FIG. 3) of the slit 11a provided on the folding line 11 is preferably at least the sheet thickness, preferably at least 1.5 times the sheet thickness. On the other hand, the upper limit of the unevenness height H2 is preferably 5 times the sheet thickness, more preferably 3 times the sheet thickness. If the unevenness height H2 is outside the above range, it may be difficult to engage the concave portion and the convex portion facing each other across the slit 11a.

The upper limit of the concave-convex pitch P2 (meandering period) of the slit 11a is preferably 6 cm, more preferably 4 cm. If the unevenness pitch P2 exceeds the upper limit, it may become difficult to properly engage the recessed portion and the projected portion that face each other with the slit 11a interposed therebetween.

In addition, since the concave portion and the convex portion facing each other across the slit 17a interfere with each other in the thickness direction of the packaging container 20, crushing of the packaging container 20 can be suppressed.

The unevenness height H3 (meandering width of the slit 17a) (see FIG. 4) of the slit 17a provided on the first folding line 16a is preferably at least the sheet thickness, preferably at least 1.5 times the sheet thickness. . On the other hand, the upper limit of the unevenness height H3 is preferably five times the sheet thickness, and more preferably three times the sheet thickness. If the unevenness height H3 is less than the lower limit, there is a possibility that the concave portion and the convex portion facing each other across the slit 17a may not be sufficiently meshed. Conversely, if the unevenness height H3 exceeds the upper limit, there is a possibility that a gap is likely to occur between the concave portion and the convex portion facing each other with the slit 11a interposed therebetween.

The lower limit of the concave-convex pitch P3 of the slits 17a (meandering period of the slits 17a) is preferably 2 cm, more preferably 3 cm. On the other hand, the upper limit of the uneven pitch P3 is preferably 6 cm, more preferably 4 cm. If the concave-convex pitch P3 is less than the lower limit, it may be difficult to easily and appropriately engage the concave portion and the convex portion facing each other with the slit 17a interposed therebetween. Conversely, if the unevenness pitch P3 exceeds the upper limit, it may be difficult to cause the recesses and protrusions facing each other across the slit 17a to interfere with each other in the thickness direction of the packaging container 20 .

The second panel 2 has a second folding line 16b extending parallel to and spaced from the inside of the second rugged edge 15b.
