As shown in the figure, bottom flaps b, c, d, and e are connected to the lower edge of the body a of the rectangular cylinder. The matching bottom flaps b and c, d and e are each folded and fixed. Further, this bottom flap is provided with fold lines f and g that are folded inwards at the bisecting positions of each corner, so that the entire box can be folded as shown in FIG.

さらに、底フラップb、dには、それぞれ切り欠きhが
設けられており、組み立て状態においては、第10図に

However, in the assembled state, the notch in the bottom flap is simply engaged, so if the opposite corner is pushed inward, the engagement will come off and the packaging box will easily become flat. . When the packaging box becomes flat in this way,
The bottom flap also becomes half erect and cannot completely close the bottom opening, causing the contents to fall out from the bottom of the box.

In this state, if you push both sides of the flat body inward,
Since the continuous side walls and end walls of each bottom wall expand around their respective corners, the bottom wall also expands and falls toward the bottom opening of the body. At this time,
The bottom flap 31 is in contact with the inner surface of one end wall 13,
Although its movement is restricted, the portion that makes contact at the crease line 35 bends upward, thereby avoiding the restriction and falling down smoothly.
