PROBLEM TO BE SOLVED: To provide a side face opening packaging box which can be manufactured at low cost. SOLUTION: According to the packaging box, side faces 1 and the other side faces 2 are adjacent to each other to form a peripheral wall. Inner flaps 4 are extended from the side faces 1, and outer flaps 5 are extended from the other side faces 2, and outer flaps 5 are pasted on the inner flaps 4 to seal the packaging box. A longitudinal tear band 7 formed between two perforation lines 6 is formed on each side face 1, where a push-in portion 8 at the start end of the tear band 7 is formed to reach the inner flaps 4 and is exposed through cutouts 9 formed on the outer flaps 5. Lateral cut lines 10 are so formed on the inner flaps 4 that each cut line 10 is separated from the ridge between the inner flaps 4 and the side board 1 across a gap. Removing the tear band 7 cuts the lateral cut line 10, thereby allowing the side face 1 to be swung opened on the ridges between the side face 1 and the side faces 2. COPYRIGHT: (C)2007,JPO&INPIT |
