PURPOSE: A packing box is provided to simplify a folding process of a box and minimize a volume when the box is transported and stored. CONSTITUTION: A first edge fold line and a second edge fold line (410,420) are equipped at both edges of a first main board, a second main board, a third main board and a fourth main board (210, 220, 230, 240). A first fold plate, a second fold plate, a third fold plate and a fourth fold plate (510, 520, 530, 540) are respectively protruded to the outside from the first main board, the second main board, the third main board and the fourth main board and folded based on the first edge fold line and the second edge fold line. A first diagonal direction fold line, a second diagonal direction fold line, a third diagonal direction fold line and a fourth diagonal direction fold line (610, 620, 630, 640) are respectively arranged in a diagonal direction of the both ends of the first fold plate, the second fold plate, the third fold plate and the fourth fold plate at the first edge fold line and the second edge fold line of the both end edges of the first main board, the second main board, the third main board and the fourth main board. A first folding ball, a second folding ball, a third folding ball and a fourth folding ball (710, 720, 730, 740) are arranged in order to penetrate through the first fold plate, the second fold plate, the third fold plate and the fourth fold plate. A second adhesion plate (320) is adhered to the inner surface of the fourth fold plate. The first main board, the second main board, the third main board and the fourth main board form a box by being folded along a first fold line, a second fold line, a third fold line and a fourth fold line (110, 120, 130, 140) in order to form a receipt space in the inner space. |
