PROBLEM TO BE SOLVED: To provide a packing box with a take-out port where the closed state of the take-out port due to a free piece can be easily formed and maintained though having a simple structure and the opening/closing of the take-out port due to the free piece can be extremely easily performed.SOLUTION: A free piece 8 is made free from a side wall 4 by breaking a part of the side wall 4 along a breakable line 5 and then a take-out port 9 is formed. A projection 10 is made at the free piece 8. The tip part of the free piece 8 is folded toward the inside of the side wall 4 via a creased line 7, the projection 10 is engaged with the peripheral edge part of the take-out port 9 and then the closed state of the take-out port 9 due to the free piece 8 is maintained.SELECTED DRAWING: Figure 4 |
