Abstract: A can end having a first flat side and a second flat side facing away from the first flat side. An opening is formed in the end surface. The opening is bounded by a closed margin of the end surface and closed by a closure piece that is separated from the surrounding end surface by a microgap extending along the margin of the end surface. A first end region of the closure piece is connected to the surrounding end surface via a pivot bearing and a tear-open member that is arranged at the first flat side so that a pivoting of the closure piece is made possible by pulling at the tear-open member. The microgap is interrupted between the first end region and the second end region by at least one holding web. A pressure relief wave is embossed into the end surface.

The metallic end region disposed within the peripheral microgap or the weakening line is received and held in the opening region of the end. The sealing frame is bonded to the fixed end surface and the closure unit is bonded to the upwardly pivotable metallic end region. Except for a possibly provided lacquer layer, the inner end side is at least largely free of lamination and the like.
