Closure for a Container with an Indication of Whether the Closure has Already Been Opened, and Different Applications for Said Closure

Abstract

Closure for a container, in particular a bottle or a cardboard/plastic composite package, with a base element including a rotatably opening closure with lateral cap jacket, an anchor ring connected to the closure cap by means of a hinge element and a free gap running substantially in the circumferential direction between the anchor ring and cap jacket wherein the free gap connects on both sides next to the hinge element and wherein there are no material bridges between the anchor ring and closure cap in the free gap that can break on initial opening. To achieve low, constant and well controlled opening forces on first opening in a closure of this type, it is provided for the closure to have a tamper-evident seal which, in the unopened state, is connected to the anchor ring via at least one breakable element and by the tamper-evident seal on the anchor ring being designed in such a way that the at least one breakable element is broken after a relative rotational movement between the closure cap and container of a maximum of 25°.

Dependencies are inferred from the claim text.
