<P>PROBLEM TO BE SOLVED: To provide a packaging box having a body properly formed into an octagonal shape by preventing folding displacement at eight joint parts of the body from affecting pasting displacement upon pasting of side parts, and by temporarily performing right-angled folding at least on a part of the eight joint parts of the body so that the repel against folding on a whole periphery of the body may be reduced and distortion may be reduced. <P>SOLUTION: The side-pasted body A is formed into a rectangular shape in cross section before the cross section of the body is formed into an octagonal shape, and the part between unfolded face plates of the body A is folded outward to form the cross section of the body into the octagonal shape. <P>COPYRIGHT: (C)2013,JPO&INPIT |
