PROBLEM TO BE SOLVED: To reduce shocks by forming boundary cuts in the front end of the top plate cut and erected in a state that a commodity is wrapped up and putting the cuts into the inside to form a fitting part and then, fitting and fixing a disc into the fitting part. SOLUTION: A top piece 3 extended through a bottom line at the top edge of the side walls 2 bent and erected at the four sides of a commodity 4 are folded at the bottom lines and put them in piles on the commodity 4. A boundary cuts 5 cut by half are formed from the front edge of a pair of top pieces 3 oposed to each other. The boundary cut 5 is shaped to coincide with the circular form of the disc 7. When the disc 7 is contained in a square case, it is shaped to form a U-shape and when it is not contained in a case, the inside zone surrounded by the boundary cuts 5 is pressed to squash the corrugated plate 8 and make a dent therein. The dent is used for the fitting part 6 and a disc 7 is fitted in the fitting part 6 and contained in an external case to complete the packing. In this way, the disc can be safely packed without shifting during transportation.
