As a result, both the lid and the bottom plate can be developed in parallel with the side wall that is connected to the lid, and the packing box can be easily crushed. Also,
Since only two slits are intermittently provided in the bottom plate, the strength of the bottom plate can be sufficiently secured before the strip-shaped break portion is peeled off, and the bottom plate of the present invention is opened during transportation of the product to open the product. There is no danger of falling.

According to a second aspect of the present invention, the band-shaped break portion is provided near a center between two sides connected to the side wall. As described above, since the band-shaped broken portion is provided near the center between the two sides connected to the side wall, the band-shaped broken portion is easily peeled off from the bottom plate. Therefore, it is possible to shorten the time for peeling the strip-shaped broken portion from the bottom plate.

According to a third aspect of the present invention, a central slit perpendicular to the longitudinal direction of the band-shaped broken portion is provided near the center of the band-shaped broken portion. As described above, since the center slit is provided near the center of the band-shaped broken portion, the band-shaped broken portion can be divided into two parts from the center, and the divided band-shaped broken portions can be simultaneously peeled off to the left and right. Therefore, it is possible to shorten the time for peeling the strip-shaped broken portion from the bottom plate.

[0010] A simple disassembled packaging box in which a rectangular cylindrical body is formed by four side walls, an openable / closable lid is provided at one end of the rectangular cylindrical body, and a rectangular bottom plate is provided at the other end. In the above, the rectangular bottom plate is characterized in that four sides thereof are connected to the side wall, and two slits are intermittently provided diagonally so that the strip-shaped broken portions are formed diagonally.

As described above, since the breaking line is formed diagonally on the bottom plate, the bottom plate is formed by peeling off the strip-shaped broken portion.
It can be divided into two and deployed. As a result, not only the lid but also the bottom plate can be developed in parallel with the side wall to which the bottom plate is connected, and the simple dismantling type packaging box can be easily crushed and discarded in a compact state. In addition, since the slits are only provided diagonally on the bottom plate, the strength of the bottom plate can be sufficiently ensured before the strip-shaped broken portion is peeled off. Therefore, there is no possibility that the bottom plate of the present invention is opened and the product falls during transportation of the product.
