Definitions

• the present invention relates to a container lid, a container, in particular a beverage can, containing this container lid, and a method for producing a container lid.
• Disposable containers for liquids have long been used in a wide variety of shapes and sizes. This is particularly often the case with beverage cans made of light metal, in which the can lid is equipped with a so-called clip closure.
• the area forming the outlet opening or cover piece is pressed in the direction of the can interior by pressing this bracket or lever lock and remains captively connected to the can lid.
• this closure is removed together with the area forming the dispensing opening or cover piece when the flip-top closure is actuated.
• Such closure systems can be found e.g. in WO 97/030902, DE 100 18 685 C2, US Pat. No. 4,148,410, EP 564 725 A1, WO 2005/056400 A1 and GB 2 379 917 A.
• the strap closure or the lever flap is rotatable about a fastener, often in the form of a rivet, in central position with the lid surface.
• the lever tab overlaps at its first end with an area of the lid surface which covers the dispensing opening. By exerting a force on this area by lifting the lever tab at the opposite second end, the dispensing opening is released. Since the first end of the lever tab usually has only a slight overlap with the area of the lid surface which covers the dispensing opening and which is often delimited by a weakening profile, it is usually necessary to arrange this opening operation from an ideally aligned lever tab, i. from the opener position
