摘要

The plastic stopper (1) has at the bottom of its skirt (10) a zone of least resistance with a guarantee band (2). The band (2) is joined to a first ring (20) connected to the skirt bottom (10) by connecting links (3). A second ring (21) is attached to the first ring by a thin peripheral zone (22) allowing the reversal of the second ring inside the first. The second ring (21) is split into two independent segments (21',21''). End stops (5) extend into the spaces (4) separating the skirt bottom and the first ring (20) of the guarantee band (2). ADVANTAGE - Enables easy removal of the stopper which is cheap.
