PROBLEM TO BE SOLVED: To easily enable the partial opening of the packaging box of an intermediate layer of a plurality of packaging boxes which are stacked. SOLUTION: The packaging box is provided with a circumferential wall 10 surrounded by wall parts 13A, 13B, 14A and 14B, and the lower end opening of the circumferential wall 10 is closed by a bottom wall 12, and flaps 17A, 17B, 18A and 18B for closing the upper end opening of the circumferential wall 10 are continuous with the wall parts 13A, 13B, 14A and 14B. A breaking part 22 is formed at least in a first wall part 14B of the wall parts 13A, 13B, 14A, and 14B, and the inside of the packaging box is exposed by breaking a part thereof in a sealed state. The breaking part 22 is sectioned in the first wall part 14B by a cutting line 23 which is spaced apart with a predetermined interval S from a boundary line 21 between the first wall part 14B and the flap 18B continuous with the first wall part 14B and extends along the boundary line 21 and a breaking means 25 which extends from both ends of the cutting line 23 toward a bottom wall 12. A grasping part 32 for grasping during the breakage of the breaking part 22 is formed at the breaking part 22. COPYRIGHT: (C)2008,JPO&INPIT
