Claims

[Scope of utility model registration request]

In a packaging box that is assembled into a rectangular parallelepiped shape using plate-like panels, the panels form a cylinder whose top and bottom are open, and a pair of side plates on long sides facing each other of the cylinder forms a V-shaped folding line diagonally from the center of the upper and lower edges, and when the upper and lower parts of the long side side plates are folded in along the folding line, the pair of short side side plates facing each other are folded. a pair of mutually opposing short sides of the cylindrical body, the upper and lower portions of which are bent by approximately half the width of the long side side plate, that is, approximately half the length of the long side, so as to close the upper and lower openings; A V-shaped folding line is formed diagonally from the center of the upper and lower edges of the side plate, and when the upper and lower parts of the short side side plate are folded in along the folding line, a pair of long sides facing each other are formed. A packaging box characterized in that the upper and lower parts of the side plates are each bent by approximately half the width of the short side side plate, that is, the length of the short side, so as to close the upper and lower openings.
