Example 1
In each of the following embodiments, a cardboard box is taken as an example of a packaging paper box.
The corrugated cardboard box according to the first embodiment shown in FIGS. 1, 2, and 3 includes two first body wall portions 1 and 1 and two second body wall portions 2 and 2. , 1 and 2 are integrally connected via folding lines 80, 81 and 82.
A glue margin piece 11 is integrally connected to a side end of the first trunk wall portion 1 via a fold line 83, and the glue margin piece 11 is bent from each of the fold lines 80, 81, 82 to form the second margin wall section. By joining to the 2 side ends, the first barrel wall portions 1 and 1 are opposed to each other, and the second cylindrical wall portion 2 and 2 are opposed to each other.

In the embodiment, by forming the lateral width L1 of the first body wall portion 1 wider than the lateral width L2 of the second body wall portion 2, the rectangular tubular body 3 having a rectangular shape in plan view is formed. In addition, the said square cylindrical trunk | drum 3 may be formed in the square by planar view.

Outer flaps 10, 10 are integrally connected to the upper and lower edges of the first body wall part 1 via folding lines 13, and inner flaps 20, 20 are connected to the upper and lower edges of the second body wall part 2, respectively. 14 are connected together via a folding line 14.

The height H1 of the outer flap 10 is formed to be half (1/2) the lateral width L2 of the second body wall portion, and the height H2 of the inner flap 20 is formed to be the same as the height H1 of the outer flap 10. ing.

Next, the shape of the inner flap 20 will be described. If the inner flap is assumed to be a square, the flap area is reduced to the left and right sides of the virtual square K (a rectangle including the parallel diagonal lines in FIG. 1). Removal portions 25 and 25 (parallel oblique line portions in FIG. 1) are formed.
Furthermore, the central part which overlaps the front edge butt | matching part 9 of the outer flaps 10 and 10 in the box assembly state is formed as a non-removal area which is not removed.

In the corrugated cardboard box according to the first embodiment, the shape of the inner flap 20 is the same as that of the second body wall portion 2 by forming triangular removal portions 25 and 25 at the left and right corner portions of the virtual square K. It is formed in a trapezoidal shape with the connecting edge 14 as a base.

(Example 2)
In the corrugated cardboard box of Example 2 shown in FIGS. 4 and 5, the shape of the inner flap 20 is such that square removal portions 25 and 25 (parallel hatched portions in FIG. 4) are formed at the left and right corners of the virtual square K.
