1. A closure assembly for a container filled or fillable with a pourable product, the closure assembly being manipulatable from an initial state to a manipulated state;
the closure assembly comprises:
a lid;
a first ring member;
a second ring member;
a coupling element connected to the lid and to one of the first ring member and the second ring member;
at least one rupturable first coupling bridge connecting the first ring member and the second ring member to one another in the initial state of the closure assembly, the at least one rupturable first coupling bridge being rupturable as the closure assembly is manipulated to the manipulated stated so that the at least one rupturable first coupling bridge is ruptured and the first and second ring members are completely disconnected from each other; and
at least one rupturable second coupling bridge connecting the second ring member and the lid to one another in the initial state of the closure assembly, the at least one rupturable second coupling bridge being rupturable as the closure assembly is manipulated to the manipulated stated so that the lid and the second ring member are no longer connected to each other by way of the at least one rupturable second coupling bridge while the lid remains connected to the one of the first ring member and the second ring member by way of the coupling element.
