Definitions

• the invention relates to a lid for a beverage can, as they are usually made of sheet metal.
• Such beverage cans which can be closed by lids are on the market in various embodiments.
• a punched pouring opening with a tearable opening closure is provided in the lid mirror.
• a region which can be pressed in and is delimited by a line of scoring or notching is provided in the lid mirror and can be torn out or pressed in by means of a lever-like grip tab in order to expose the pouring opening.
• the area that can be pressed in can be completely detachable from the cover mirror or can be permanently connected to it, that is to say captively.
• beverage cans cannot be resealed sufficiently tightly in cases where the contents are not emptied all at once. However, this would be necessary if the content was to be removed in portions and at intervals without significant loss of quality.
• this lid is to be designed especially in the event that the pouring opening is only exposed by breaking open a scratch or score line.
• Counter-engagement elements on the inside of the wall and the outside of the closure can be applied with a sufficiently high closing force for tightly reclosing the pouring opening.
• Intervention or counter-engagement elements working and designed in the manner of a bayonet catch are particularly suitable Intervention or counter-engagement elements working and designed in the manner of a bayonet catch.

• a particular advantage of the embodiment according to claim 6 or claim 7 is that the design is particularly suitable for lids in which the pouring opening is only exposed by breaking in a score or score line.
• the relative rotary movement of the bayonet-like interlocking engagement and counter-engagement elements can be used for controlled breaking in and exposing the opening.
• the breaking-in process requires only a very small amount of force, since the rotational movement and the positive engagement of the parts rotating relative to each other result in a considerable increase in force.
