Abstract

A tamper-evident closure (10) for a container is provided. The closure (10) comprises a base (20) attachable to a container neck (50). The base (20) comprises a sidewall (21) having a tamper-evident drop band (40). The band includes an abutment (43) for engaging the container neck to cause the band to break away from the sidewall if an attempt is made to remove the closure from the neck once fitted. The band (40) further comprises an extension (45) against which the sidewall pushes if the closure is reapplied to push the band (40) away from the base (20).
