<p>PROBLEM TO BE SOLVED: To eliminate the necessity to individually prepare partitioning plates, save labor for the building up, and reduce the preparation cost for the partitioning plates by a method wherein an area which is surrounded by incisions and a folding line, is provided on a side wall, and the area is cut off at the incisions, and is bent to the inside of the container. SOLUTION: At the centers of a side wall 2A and a side wall 2B, a rectangular area being surrounded by incisions 5, 6, 7 and a folding line 4, is provided. When this packaging container 1 is built up, both side walls 2A, 2B are bent so as to be rectangular to a bottom wall 13, and side walls 11, 11 are bent so as to be rectangular to the side wall 2A, and in addition, both bottom wall end pieces 14, 14 being connected to the right and the left of the bottom wall 13, are bent so as to be rectangular to the bottom wall 13, and bonded to the insides of the side walls 11, 11. Then, side walls 12, 12 are bent so as to be rectangular to the side wall 2B, and both side walls 12, 12 are bonded to the insides of both side walls 11, 11. Then, the rectangular area is cut off at the incisions 5, 6, 7, and is bent by the folding line 4 to the inside of the container at approx. 90 deg., and a partitioning plate 3 is formed.</p> |
