Reclosable container lid, containers including beverage cans containing said reclosable container lid, methods of manufacturing such containers, and use of said reclosable container lid

Abstract

A reclosable container lid includes a lid surface having an upper side, a lower side, a circumferential edge, and a zone for a dispensing aperture delimited by a circumferential weakening profile. A lever tab is pivotably fastened to the lid surface via a fastener for at least partly opening the dispensing aperture. The lever tab has first and second end portions, wherein the first end portion, in the opening position, at least partly overlaps with a section of the zone for the dispensing aperture. The lever tab also has a closure module comprising a closure collar that rests against the upper side of the lid surface and which, in the closure position, extends along the dispensing aperture in a sealing manner. The closure module also includes a reclosable aperture closure framed by the closure collar. A method of manufacturing reclosable containers using the container lids is also disclosed herein.
