A packing box with a flexible section

摘要

The present invention relates to a packing box (10). The packing box is characterized by comprising a lateral bending line (143a) which begins from a bending point (142) and which extends between the upper surface (15) and the lower surface (16); another lateral bending line (143b) which extends between the upper and the lower surface (15, 16) so that there is a certain angle between it and said lateral bending line (143a); an intermediate bending line (145) which begins from the bending point (142) and which extends between the upper and the lower surfaces (15, 16) so as to remain between the lateral bending lines (143a, 143b); and a lower bending line (144) which extends along the lower surface (16) between the ends of said lateral bending lines (143a, 143b).
