  • a cylindrical body, and a pair of lids which each are provided in a pair of openings of the cylindrical body;

    wherein;

    the pair of lids each have a tongue which extends from their heads, the tongue being disposed so that it is opened and closed on its connection portion as a crease to the body of the packaging box with respect to the body of the packaging box, and a lid gluing portion which is arranged in a specific area on the outer surface of each tongue;

    the body of the packaging box has a pair of body gluing portions which are individually glued to each lid gluing portion, the body gluing portions being arranged in each specific area of both open-side ends where they are placed on top of and joined to each tongue, and at least one transverse split-open portion which guides a fracture from one opening to the other opening in a side face of the packaging box; and

    both open-side ends have side-end split-open portions which guide a fracture so that the body gluing portions are separated from the body when the body gluing portions are kept glued to the lid gluing portions, the side-end split-open portions being arranged so as to surround the body gluing portions.
