Abstract

Abstract Translated from German Das Garantieband (3) der Schraubkappe (1) hat eine Sollbruchstelle (11), an welcher das Garantieband über seine gesamte Höhe auftrennbar ist. Neben der Sollbruchstelle ist eine vorzugsweise fensterförmige Entlastungsöffnung (12) angeordnet, welche die Dehnbarkeit des Garantiebandes beim erstmaligen Aufschrauben der Kappe verbessert. Die Sollbruchstelle besteht aus wenigstens zwei Materialstegen, von denen ein unterer am unteren Rand der Schraubkappe angeordnet ist. Beim erstmaligen Abschrauben wird ein Kräftefluss im Garantieband erreicht, bei dem die Entlastungsöffnung nicht mehr wirksam wird. <IMAGE> The guarantee band (3) of the screw cap (1) has a predetermined breaking point (11) at which the guarantee band can be separated over its entire height. In addition to the predetermined breaking point, a preferably window-shaped relief opening (12) is arranged, which improves the elasticity of the guarantee band when the cap is screwed on for the first time. The predetermined breaking point consists of at least two material webs, one of which is arranged at the lower edge of the screw cap. When unscrewing for the first time, a flow of forces in the guarantee band is achieved in which the relief opening is no longer effective. <IMAGE>
