The two side surfaces 16 are overlapped in parallel with each other, but the folding lines 24 and 26 are slightly opened by the elastic force of the blank sheet, and the direction away from the side surfaces 18 and 14 as the distance from the folding lines 24 and 26 increases. The pushing portions 50 and 52 intersect, the end face 51 and the end face 53 are locked, and the crease lines 24 and 26 are prevented from opening more than a certain amount. Thereby, a flat folded state is maintained. The folding folds 56 and 60 are formed by sewing lines in which short cutting lines are arranged at a relatively long predetermined interval, and are set so as to generate repulsion when folded in half, so that the packaging box 10 returns to its original shape. Energize to. However, since the pushing parts 50 and 52 are faced and locked by the end faces 51 and 53 intersecting in the return direction of the packaging box 10, the end faces 51 and 53 are pressed against each other and reliably locked and released. There is no. Further, at the end portions 48b and 48c of the finger pushing break line 48, uncut portions are located between the finger breaking line 54 and 58, and the finger pushing break line 48 and the disposal break lines 54 and 58 are connected to each other. When cut, small protrusions that are traces of uncut portions are formed so as to protrude, and the protrusions engage with each other and are more reliably locked.

  According to the packaging box 10 of this embodiment, after use, it can be folded by a simple operation to make it compact and can be disposed of or recovered. When performing the folding operation for disposal, the shape is maintained by cutting the side surface 16 with the finger pushing break line 48 and the disposal breaking lines 54, 58 by simply pushing the pushing portions 50, 52 with a finger. By releasing the function and folding the box while pressing the push-in portions 50 and 52, it can be folded flat with one touch. And the pushing parts 50 and 52 are faced and locked by the end surfaces 51 and 53 which cross | intersect the direction in which the packaging box 10 returns to an original shape in the folded state, and it prevents that the packaging box 10 returns to an original shape. The flat folded state can be maintained. Thereby, the conveyance processing in the case of disposal or resource recovery can be easily performed. The folding folds 56 and 60 are set so as to generate repulsion when folded in half, and are urged in the direction in which the pushing portions 50 and 52 come into contact with each other. . Further, when the finger pushing break line 48 and the disposal break lines 54 and 58 are cut, the projections formed by cutting the uncut portions are engaged with each other and are more reliably locked. Further, the packaging box 10 has a simple assembly process, can be applied to an automatic packaging device, and has high production efficiency.
