Abstract (en)
[origin: WO2023012557A1] The invention relates to a method for producing pull-off closures (1) of the ring-pull type to close containers, in which a sheet of metallic material is cut and drawn to obtain a plurality of shells (3) each with a central closing wall (4) and a peripheral skirt wall (5) and in which each shell (3), after drawing, is scored to obtain at least one circumferentially extended score line (7, 9) that forms a preferential breakage line that is broken by pulling a tear element applied to the shell (3). The invention further relates to an apparatus for producing pull-off closures and to a pull-off closure.
