PURPOSE:To contrive the packaging of each item individually in a simple, rapid and compact manner by a method wherein, after inserting a locking piece completely into a locking hole and the locking piece is strongly pushed down to resiliently deform an arcuate projecting part under the locking piece. CONSTITUTION:After blank board A is folded to engage its side edge 1 with the opposite side edge 2, a nearly T-shaped locking piece 4 is inserted into a locking hole 3 as far as it will go while bending both the end parts toward each other with overlapping pieces 5 and 5 extending along the underside of a first folding face A1. In this condition, since an arcuate projecting part 3a is made to underlie the locking piece 4, the locking piece 4 is strongly pushed down to resiliently force down the arcuate projecting part 3a provided at the edge of the locking hole 3, the locking piece 4 is passed under the arcuate projecting part 3a and the arcuate part 3a overlies the locking piece 4. For this reason, the T-shaped locking piece 4 and the arcuate projecting part 39 forms so strong an interlocking joint as to withstand the weight of a motor M. |
