The center area 28 has a plurality of first teeth 38 with a high tooth height and a plurality of second teeth with a smaller tooth height, one of the first teeth being situated at the V-shaped apex portion and the other first teeth 38 being situated at a prescribed spacing centered around the first tooth 38 at the apex portion, and the second teeth being situated between the first teeth. When the cutting edge is mounted at a prescribed location of the packaging container, the tip section of the first tooth 38 situated at the V-shaped apex portion is curved toward the side opposite the front wall of the cover of the packaging container. A straight line L2 connecting the tips of the second teeth is located between a straight line L1 connecting the tips of the first teeth and a third straight line connecting the bases of the first teeth and second teeth. The side areas 30 comprise a plurality of side teeth 31, and the tips of the side teeth 31 are situated on line L2 or between lines L2 and L3.
