<P>PROBLEM TO BE SOLVED: To provide a perforation structure and a packing container with a lid using the structure in which a feeling of use is improved because it becomes difficult to touch a cutting part during use. <P>SOLUTION: A separation perforation 16 is made in a corrugated form which uses the container 11 side for a solitary meal as a bottom by a plurality of openings 21 formed with a certain interval therebetween in a boundary between the container 11 (use assumption area) for a solitary meal and the individual flange 14 (removal area). The portion 22 to be cut of the separation perforation 16 is formed in the bottom part of the corrugated form shown with the dashed line (1). When the portion 22 to be cut is cut, the sharp burr 23 is produced toward the outside at the portion 22 to be cut of the container 11 for solitary meal as shown in (2). However, the portion 22 to be cut is formed at the bottom part of the corrugated form so that the cutting part, which is left in the use assumption area by cutting, is located to be closer to the container 11 for solitary meals than a straight line shown with a two-dot chain line in (1). Therefore, it becomes difficult to touch a cutting part during use and a feeling of use is improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
