PACKING BOX

PROBLEM TO BE SOLVED: To provide a packing box which exhibits sufficient strength and is positioned easily when stacked in multiple stages.SOLUTION: The packing box is obtained by bending a plate-like member formed from a bendable material and has a bottom face part 9 being the bottom thereof, side face parts 8a, 8b, 8c, 8d for forming the periphery of the bottom face part, and top face parts 7a, 7b being lids for covering the space formed by the bottom face part and the side face parts. The bottom face part has first notched parts formed by cutting off four corners each of which is the area surrounded by bending lines for forming the side face parts. The side face part has ridgeline parts for forming the side faces, by each of which the first notched part and the bottom face part are defined, by bending the outlines of the first notched part in such a state that the side face part is bent perpendicularly to the bottom face part. The top face part has second notched parts each of which is bent relatively to the side face part and formed oppositely to the first notched part while the space formed by the bottom face part and the side face parts is covered with the top face part.
