An inner flap connected to the upper and lower edges of the end plate, and an outer flap connected to the upper and lower edges of the side plate and the dividing side plate are sequentially horizontally bent to close the upper and lower openings. Along with extending the superposed piece connected to the upper and lower edges to the side, extending the extended piece from the outer flap of the dividing side plate having a partition wall, the superposed piece and the extended piece,
Each was superimposed on the inner surface of the outer flap on the same side.

[0011] In this corrugated cardboard box, the deflection of the partition wall is regulated by the overlapped piece during manufacture, so that the fixed piece is fixed to a predetermined position on the side plate with high accuracy.

Further, in the assembled state, not only the inner flap but also the overlapped piece and the extended piece overlap with the outer flap on the same side, respectively. Equally supported. From this, it is possible to design the contents while protecting the contents and making effective use of the strength.

Further, in the folded state, the overlapped piece and the extended piece are sandwiched between the opposing outer flaps, so that when they are bundled and stacked, a stable packing form is obtained.
