Definitions

  • the invention relates to a lid for closing a beverage can made of sheet metal.
  • lids are commercially available in various embodiments.
  • Lids are well known in which a break-in area surrounded by a crack or score line is provided in the lid mirror, which can be brought to break-in with the aid of a lifting-shaped bottle , With the handle tab the collapsible area can be completely separated from the lid mirror or pivoted relative to it only into a position that does not impede the pouring out.
  • Lids are also known in which a pre-punched pouring opening is provided, while a tearable closure element hermetically seals the opening
  • a particular advantage is that the areas of the lid lying outside the core wall are left untouched by the invention, so that they remain as before and allow conventional connection with commercially available cans.
  • the rotational engagement for reclosing also achieves a high closing force, so that in the reclosed state a loss of quality of the remaining drink (escaping carbon dioxide) is not to be feared or only to a very small extent
  • the engagement elements and counter-engagement elements of the twist lock attached in the cover mirror are designed such that they can be brought into and out of engagement with one another in the manner of a bayonet lock (claim 2).
  • the closure element consists of dimensionally stable material, in particular metal (claim 3)
  • metal claim 3
  • a separate sealing element is assigned to the closure element, which comes into direct sealing engagement with the edge of the pouring opening and is held securely in this position by the closure element (claims 8 to 10).
  • the closure element can remain captively connected to the cover mirror (claim 11, 16, 17).
  • the invention proposes several possibilities, firstly a pin-slot guide, wherein a rivet engages in an arcuate slot opening on the closure piece in order both to pivot it around the Opening edge of the pouring opening, as well as tilting of the sealing portion of the n piece against the actuating arm in which the pin-slot guide is arranged, another time the use of an intermediate layer, which is rotatably supported around the pouring opening (the opening edge) and is held and extends away from the opening at the end of the intermediate piece remote from the opening, a hinge joint is provided, in particular by an edge-side engagement from to
  • a hook-shaped counter-engagement element is formed in such a way that it engages in the engagement element which is also hook-shaped on the cover mirror upwards and radially outwards and which is formed on the opening edge or forms the opening edge
  • a circumferential sealing lip can be provided in the lower region, which cooperates sealingly with the sealing section of the closure piece, which is recessed downwards, in the locking engagement
