Abstract (en)
[origin: WO2006074661A1] The present application relates to a method for manufacturing a lid (2) and a lid (2) for a container, which lid comprises an outer lid (12) and an inner lid (14) , which are rotatably connected to each other via a centrally positioned connection element (16) , where the connection element serves as a force transferring means in an axial direction. The manufacturing method comprises at least the following steps, execution of at least one process of forming a projection (18) , which process comprises at least one double operation, which double operation comprises a first stamping in a matrix (20) with a punch (22) with a first large diameter (24) and a first large rounding (26) (large radius of curvature) , and subsequently executing a second stamping with a punch (30) that has substantially the same diameter and a second smaller rounding (32) , placing the connection element around the projection, placing a rubber block (40) inside the projection, a third stamping operation, where a punch (50) is pressed toward the rubber block, while the projection is supported by supporting means (42) from the opposite side, attachment of the inner lid to the connection element.
