ABSTRACT:
At least one cutting element on a closure having a spout and a screw cap, which can be screwed thereon and which has a tamper-evident band. The tamper-evident band is joined to a lower edge of an outer wall of the screw cap via specified rupture location bridges. The at least one cutting element outwardly projects through an intermediate space. When the screw cap is unscrewed for the first time, the at least one cutting element cuts through the specified rupture location bridges. A distance between the tamper-evident band upper edge and the lower edge of the screw cap is provided with a measure whereby enabling the distance to be surmounted only occurs once all specified rupture location bridges are cut through.
