A tamper-evident overcap (100) for a closure (101) comprises a cap superior part (100A) fixable to an exterior surface of the closure (100), and a co-axial annular inferior part (100B) which is releasably connected to the cap superior part (100A) and comprises at least one inwardly directed projection (6) facing an interior of the overcap and at least one zone of weakness (5). At least one projection (6) of the annular inferior part (100B) is capable of interacting with at least one projection (3C) located on the exterior surface of the closure (101). The torque of the engagement of the projections (6, 3C) of the tamper-evident overcap (101) and the closure (101) causes the annular inferior part (100B) to break at the zone of weakness (5) if an attempt is made to open the closure (101) without the annular inferior part (100B) having been removed from the tamper-evident overcap (100). |
