PROBLEM TO BE SOLVED: To provide a packing box of which a lid part can be opened easily with small force, wherein the packing box includes the lid part connected through a fold line from an upper end of a rear surface part of a sleeve-like part having a front surface part, a right side surface part, a left side surface part, and the rear surface part, and a lid flap connected to a tip of the lid part through a fold line, and the packing box is closed by inserting the lid flap to an inner side of the front surface part.SOLUTION: A cutout 12 is formed on an upper end of a front surface part 10. A lid flap 80 includes a main body part 82, and a rotation piece part 90 connected to the main body part 82 through fold lines 94b, 94f. When a packing box A is closed, a bottom side part 12b of the cutout 12 is positioned above the fold lines 94b, 94f of the lid flap 80. When the rotation piece part 90 is rotated around the fold lines 94b, 94f, the rotation piece part 90 abuts on the bottom side part 12b, and when the rotation piece part 90 is rotated further, the lid flap main body part 82 is lifted by the rotation piece part 90.SELECTED DRAWING: Figure 1 |
