In addition, the four corner reinforcement members are connected to the inner lid flaps or the inner bottom flaps to form the four stepped bumps. A piece of corrugated paper and cut each corrugated paper piece It is formed by bending at a substantially right angle along the eyes.

[0008]   In this configuration, four pieces of corrugated cardboard from the inner lid flap or the inner bottom flap. Is cut off and each of the cut pieces of corrugated cardboard cuts four corners. The chemical conversion member is formed. The inner lid flap and the inner bottom flap have almost no compressive strength of the packaging box. Cut the corrugated cardboard piece from the inner lid flap or inner bottom flap that does not contribute However, the compressive strength of the packaging box does not weaken. On the other hand, attach each corner reinforcement member to the inside 4 of the side plate. By arranging them in the corners, the compressive strength of the packaging box is strengthened. That is, each corner The reinforcing member is formed by a piece of corrugated cardboard cut from the inner lid flap or the inner bottom flap. Since it was made, it does not require additional paper material to form the corner reinforcement member. Instead, the compressive strength of the packaging box can be increased by using the same amount of paper. Therefore, the use of paper Even if the dose is reduced and the paper thickness of the packaging box is reduced, the compressive strength of the packaging box can be maintained. It will be possible. Also, each corner reinforcing member is formed by bending a corrugated paper piece at a substantially right angle. Since it is formed, the strength is increased, which further increases the compressive strength of the packaging box.
