The tamper-evident skirt is formed of a plurality of temper-evident pieces 10 connected respectively with breakable bridging parts 12 to the lower end of the skirt wall 4. Each of the tamper-evident pieces 10 is in a arcuate shape and positioned so as to extend in the tangential direction at the outside in the radial direction of the skirt wall 4 with its top positioned at the upside thereof. A projected part 20 for engagement is provided at one end in the longitudinal direction of each of the tamper-evident pieces 10, while an engagement groove 30 is provided at the underside at the other end in the longitudinal direction of the tamper-evident piece, and a protuberance 40 for enagement is formed in the radial direction at the underside at the outer edge of the tamper-evident piece.
