Each finger-hanging folding portion 20 is provided so as to correspond to each of the packages 1 packed in the packaging box 10. Each folded portion 20 may correspond to two adjacent packages 1, 1.
[0012]
As shown in FIG. 2 and FIG. 5A, the finger hooking fold 20 extends over the side plate 11 (or 12) and the flap 13 (or 14) connected to the side plate 11 via the connecting line 21. Cuts 22, 22 (all cut lines or half cut lines in the case of a cardboard box) which are provided as described above, and a first ruled line 23 connecting one end of the two cuts 22, 22 formed in the flap 13 to each other. (A half cut line is also possible) and a second ruled line 24 (which is formed on the flap 13 and connects the midpoints of the two cuts 22, 22 and is located between the first ruled line 23 and the continuous line 21. A half cut line is also possible), a third ruled line 25 connecting the other ends of the two cuts 22, 22 formed in the side plate 11 to each other (a half cut line is also possible), and two cuts 22 formed in the side plate 11. , 22 are connected to each other and a third ruled line 5 and accompanied by (or a half-cut line) fourth ruled line 26 located between the continuous 設線 21. The folding portion 20 is set in a range surrounded by the two cuts 22, 22 and the first and third ruled lines 23, 25.
[0013]
The finger hooking folding section 20 makes the length of the first ruled line 23 and the length of the third ruled line 25 different from the length of the continuous line 21. Specifically, the length of the continuous line 21 is set to the minimum length (for example, 50 mm) required for the folding operation of the folding part 20 and the finger hanging on the exposed surface of the packaged object 1, and the first ruled line 23 and the The length of the ruled line 25 (for example, 25 mm) is shorter than the length of the continuous line 21 (FIG. 5A, (the unit of display length in FIG. 5 is mm)). Then, the cuts 22, 22 are connected so that the interval between the two cuts 22, 22 from the side of the connecting line 21 toward the first ruled line 23 or the third ruled line 25 is gradually reduced. It was provided obliquely to the line 21. Accordingly, the lengths of the second ruled line 24 and the fourth ruled line 26 are also shorter than the length of the continuous line 21.

[0024]
The difference between the finger folding part 20 and the first embodiment is that not only the length of the first ruled line 23 and the third ruled line 25 is different from the length of the continuous line 21 but also the first ruled line. That is, the length of the ruled line 23 and the length of the third ruled line 25 are different from each other. The length of the first ruled line 23, the length of the continuous line 21, and the length of the third ruled line 25 are shortened in this order, and the length of the first ruled line 23 is reduced by the folding operation of the folding part 20 and the packaged object 1. The length of the third ruled line 25 (for example, 25 mm) is made shorter than the length of the first ruled line 23 by setting the minimum length (for example, 50 mm) required for finger hanging on the exposed surface of the first ruled line 23. Then, the cuts 22, 22 are formed so that the interval between the two cuts 22, 22 from the side of the first ruled line 23 to the side of the third ruled line 25 via the continuous line 21 is gradually reduced. Is provided obliquely with respect to the continuous line 21.
[0025]
In the packaging box 10 of the first to third embodiments, the two cuts 22 provided so as to straddle the side plate 11 (12) and the flaps 13 (14) are as shown in FIG. In a state in which the packaged object 1 can be taken out by opening the flaps 13 (14) of the packaging box 10, the cut surfaces 22A, 22A of the packaging box 10 with respect to the side plate 11 and the surface of the flap 13 are placed.
