The first bottom cover piece and the second bottom cover piece are each provided with a glued piece that is glued to one of the adjacent bottom flaps and an insertion piece that protrudes toward the other adjacent bottom flap. The pair of bottom flaps is provided with a slit into which the insertion piece is inserted. In the assembled state of the box-forming piece, the insertion piece is inserted into the slit and the bottom portion is locked.

  In addition, when the slit is assembled after the necessary parts of the box-forming piece are bonded, the insertion piece of the first bottom lid piece and the second bottom lid piece follows a locus on which the surface of the bottom flap slides. When the first bottom cover piece and the second bottom cover piece and the pair of bottom flaps are assembled to be flush with each other, the ends of the slits are formed. , Located near the protruding step of the insertion piece, the step of the insertion piece is locked to the end of the slit.

  Further, the box-forming piece is provided with a buffer partition piece for holding the contents, and the partition piece is a rising piece that rises in parallel with the one side surface from the bottom portion in the assembled state of the packaging box. An upper surface piece that is continuous to the upright piece and is positioned substantially parallel to the bottom portion, and a gluing piece for partitioning that is continuous to the upper surface piece and glued to the one side surface is separated from each other by a crease line On the crease line between the upright piece and the upper face piece, a punching portion into which the contents are fitted is formed.

  The buffer partition piece is connected to the end of the bottom flap. Furthermore, the said slit is located in the side edge part of the said sticking piece in an assembly state, and is formed so that it may be substantially hidden.

  The packaging box of the present invention can be easily assembled with a simple structure in a state after being glued, and the bottom part is composed of a first bottom cover piece, a second bottom cover piece, and a pair of bottom flaps. So that they can be stably assembled by either automatic assembly by machines or manual assembly.
