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.
Claims21
A multi-component closure, in particular for a liquid containing cardboard packaging, comprising:
- a bottom part with a laminar support and a neck arranged thereto in one piece, where the neck comprises:
- a neck opening;
- a restring enclosing the neck;
- and
- at least one first locking element, which is arranged between the neck opening and the restring;
- a screw cap with a retaining ring and with a closure cap attached on the retaining ring via a hinge, where the retaining ring is arranged at least partly between the support and the restring around the neck and is kept rotatable by the restring;
- and
- wherein the closure cap comprises at least one 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;
- and
- wherein the hinge comprises a flexible joint arranged between the retaining ring and the closure cap,
- wherein an axis of rotation of the flexible joint is closer to a plane spanned by the neck opening than the first locking element and the second locking element and/or
- wherein the flexible joint is arranged above the first locking element and the second locking element with respect to the laminar support of the bottom part.
