Two other side surface forming pieces that form the side surfaces of the one bottom surface forming piece, and the one bottom surface forming piece that is integrally formed with the one bottom surface forming piece through a first fold line. One piece and the other side surface forming piece formed integrally with the one one side surface forming piece via a second fold line formed in a direction intersecting the first fold line. The first packing piece to be formed has the same configuration as the first packing piece, and the front A first packing piece and a second packing piece arranged in a rotationally symmetric position, wherein the first packing piece and the second packing piece are arranged with the one side surface forming piece interposed therebetween. One connection piece formed integrally with the one side surface forming piece via a third fold line formed on the opposite side of the fold line, and the second fold with the other side surface forming piece interposed therebetween The first packing piece and the second packing are connected via the other connecting piece formed integrally with the other side surface forming piece via a fourth folding line formed on the opposite side of the line. A notch portion is formed in a straight line between the two pieces, and the two bottom surface forming members are formed so as to be connectable to each other via a locking portion.

  The packing material which concerns on this invention WHEREIN: The said latching | locking part is by the slit formed in the direction which cross | intersects with respect to the said 1st fold line from the outer periphery of the said bottom face formation piece on the opposite side to the said 1st fold line. It may be configured.

  In the packing material according to the present invention, a plurality of the first packing pieces and the second packing pieces may be connected via a connecting portion.

  The packing material according to the present invention is formed integrally with the bottom surface forming piece of the packing piece of either the first packing piece or the second packing piece via a fold line, and outside the one side surface forming piece. It is formed integrally with the side surface outer piece via a side surface outer piece formed in a superposed manner and another fold line formed on the opposite side of the fold line across the side surface outer piece, and opposed to the bottom surface. And a lid forming piece for forming a lid to be arranged.

  According to the present invention, it is possible to reduce the area of the sheet material and the folding man-hour, and to obtain various excellent effects such as omitting the gluing operation and increasing the efficiency of the assembly operation of the packaging box. it can.
