PROBLEM TO BE SOLVED: To provide a packing box in which a cushioning material inside of an upper case does not fall down when a packing is opened and a joint is pulled out to lift the upper case in a packing box in which a bottom case and the upper case are connected with each other by the joint. SOLUTION: The joint 40 is inserted into a through-hole 12a of a bottom flap 12 of the bottom case 10 to connect the bottom flap 12 with the side part 22 of the upper case 20. In this instance, tongue pieces 22a and 22b of the upper case 20 are pushed into a window part 32a of the cushioning material 32 with the joint 40. Even when the joint 40 is pulled out and the connection between the bottom case 10 and the upper case 20 is released, the connecting relation between the upper case 20 and the cushioning material 32 is kept by the tongue pieces 22a and 22b. Even when the upper case 20 is lifted when the packing is opened, as the cushioning material 32 can be supported by the tongue pieces 22a and 22b, it does not fall down. COPYRIGHT: (C)2007,JPO&INPIT
