<P>PROBLEM TO BE SOLVED: To provide a packaging box capable of compactly storing articles with an inclined step, being easily sealed and being effectively stacked. <P>SOLUTION: A pair of side plates 1 each having a high stage section, a step section and a low stage section and a pair of high and low side plates 2 orthogonal to the side plates 1 are formed continuously to each other. A high stage plate 4, a step plate 5, and a low stage plate 6 are extended from the opposing side plates 1, the step plate 5 is inclined to the high stage plate 4 and the low stage plate 6, the high stage plate 4 is received by a folding piece 7 extended from the high end face plate 2, the step plate 5 is received by a folding piece 8 extended from the high stage plate 4, and the low stage plate 6 is received by the folding piece 7 extended from the low end face plate 2. Further, a locking piece 11 is inserted into a locking hole 12 in response to bending along folding lines 9, 10 of one of the step plate 5 and the low stage plate 6, and both the step plate 5 and the low stage plate 6 are sealed by connecting them with each other in response to restoration of the bending. <P>COPYRIGHT: (C)2009,JPO&INPIT |
