PROBLEM TO BE SOLVED: To solve the problem that, when a closed lid of a corrugated box or the like is opened at the center of the lid, the lid has to be cut open toward both left and right, which takes a force for opening twice as strong as a force for opening in one direction to make the opening of the lid difficult, and a removed unsealing cutout forms an opening that allows a foreign matter, such as dust, to come into the box, which deteriorates the preservation condition of a content, such as a food, of the box when it is used again. SOLUTION: A packaging box 10 is provided. When the packaging box 10 is closed, opening/closing edges 3a and 3b of the lids 9 and 12 are fixed on side panels 5 and 6 forming an opening, using a closure means 28. An unsealing cutout 28, which can be cut out along a cut line 29 consisting of a plurality of incisions, is formed at the corner end of the opening/closing edge 3a. COPYRIGHT: (C)2005,JPO&NCIPI
