Abstract
Method for forming a closure arrangement for a container, the closure arrangement having at least one lid element with an opening and a closure element arranged on the lid element for the repeatable closure of the opening, the closure element comprising a plurality of components which can be moved relative to one another; wherein the lid element has an outer side and an inner side and the opening has an opening edge and an opening plane formed by the opening edge; wherein the closure element has, as a first component, at least one frame part with a window which is non-detachably arranged on the opening edge.
Claims13
A method of manufacturing a closure arrangement for a container, the closure arrangement comprising at least one lid element with an opening and a closure element arranged on the lid element and configured to repeatably close the opening, the closure element comprising a plurality of components configured to move relative to one another;
- wherein the lid element has an outer side and an inner side and the opening comprising an opening edge and an opening plane formed by the opening edge;
- wherein the closure element comprises a first component, comprising at least one frame part with a window, the frame part being non-detachably arranged on the opening edge, the method comprising:
- providing the lid element with the opening;
- providing the frame part;
- arranging the frame part in the opening, wherein the frame part extends on both sides of the opening plane;
- plasticly deforming at least a subsection of the frame part consisting of a plastic material, so that the frame part extends around at least a part of the opening edge, so that an inseparable positive first connection is formed between the frame part and the lid element with respect to an axial direction extending transversely to the opening plane
- whereby plasticly deforming at least the subsection of the frame part is a cold forming process.
