Abstract: A Multi-component closure is proposed, which comprises a bottom part with a laminar support and a neck arranged thereto in one piece, which comprises a neck opening, a restring enclosing the neck and a first locking element, which is designed in between a neck opening and the restring. A screw cap is provided with a retaining ring and with a closure cap attached via a hinge to the retaining ring, where the retaining ring is kept rotatable by the restring, and where the closure cap comprises at least a second locking element, which in a closed state acts together with the at least one first locking element, to close the neck opening with the closure cap in a liquid-tight manner and that in the closed state a turn of the screw cap around the neck in a first direction causes an opening of the screw cap.

Abstract: A multi-part closure is proposed with a lower part having a flat support and a neck integrally arranged thereon. A screw cap is provided with a retaining ring and with a closure cap fastened to the retaining ring via a film hinge, the retaining ring being arranged at least partially between the support and a detent ring around the neck and being rotatably held by the detent ring. Further, the film hinge includes a first hinge member forming a portion of the retaining ring, and a second hinge member forming a portion of the closure cap. A three-portion hinge includes a center portion and two outer portions spaced from the center portion and connecting the first hinge member to the second hinge member. The at least two outer parts are designed to exert an at least partially increasing tensile force up to a limit angle during a rotation about a line of rotation and to exert an at least partially decreasing tensile force during a further rotation from this limit angle.
