Abstract
A method of forming a closure member may include: providing a support member with an outer support surface; providing a member including a first member made of electrically conductive material, wherein the first member includes a first tubular sleeve extending along a longitudinal direction between a first top end and a first bottom end; positioning the member on the support member; applying a magnetic field on the member to deform at least a portion of the first tubular sleeve around the support member to form the closure member; and/or removing the formed closure member from the support member for subsequently fitting the formed closure member on a neck of a container or a closure body.
