PROBLEM TO BE SOLVED: To make a tab easily pinchable and to make break-off of a vertical breaking means and an annular breaking means extremely easy by a method wherein the tab is formed in a shape having an arcuate part extending from a rise part arcuately above the annular breaking means along the outer circumferential face of a main part of a skirt wall. SOLUTION: In order to unseal a mouth-neck part by removing a container cap 2, an arcuate part 38 of a tab 8 is forced to the outside to break a thin connecting piece. Then, the arcuate part 38 is held and pulled in a required direction to break a vertical break means 42 formed at a tamper-evident skirt part 16. More specifically, a thin part formed with a groove is broken, and further an annular breaking means 12 is broken. Further more specifically, an annular thin part formed with an annular groove is broken. Thus, the tamper-evident skirt part 16 is separated from a main part of a skirt wall 6 and removed from the mouth-neck part. |
