The band comprises a first portion () directed downwardly from the cap skirt and a second portion () which extends from the lower end of the first portion and which is folded over inwardly and back in the direction of the head plate for engaging behind a securing ring on a container neck. At least one extension () is provided in axial extension of the second portion. The extension is provided with one or more notches () and the interior of the skirt is provided with one or more corresponding projections () which locate in the notches when the second portion is folded. Wherein when the closure is unscrewed the skirt breaks away from the band, and when the skirt is reapplied to the container neck the projections can push on the extension to ensure that the band drops away from the skirt.
