Abstract

Ein Problem liegt bei Verschlußdeckeln darin, eine Absenkung eines Öffnungsbereiches zu erlauben und eine höhere Druckfestigkeit zur Verfügung zu stellen, so daß mechanische Knick-Verformungen des abgesenkten Bereiches bei Einwirken von flächigem Druck von unten bei höheren Drücken nicht zu befürchten sind. Vorgeschlagen wird dazu ein Verschlußdeckel aus Blech für Getränkedosen mit - von innen nach außen - einem Deckelspiegel (10), einer umlaufenden Dämpfungssicke (20) und einem Falzrand (21), bei welchem Blechverschlußdeckel im Deckelspiegel (10) ein an die Form einer Grifflasche (9) und eines Öffnungsbereiches (8) angepaßter Flachbereich (40) gegenüber der Ebene des Deckelspiegels (10) abgesenkt ist. Der Flachbereich (40) weist längere (42, 43) und kürzere (45, 46) Randbereiche auf, die ihn zum nicht abgesenkten Rest des Deckelspiegels (10) hin begrenzen. Zumindest einer der kürzeren Randbereiche (45) verläuft sanft von der Ebene des abgesenkten Flachbereiches (40) zu der höher liegenden Ebene des Deckelspiegels (10) ansteigend (α), zur Schaffung eines elastisch nachgiebigen Übergangs bei Einwirken von flächigem Druck von der Unterseite des Deckels. Auch ein Werkzeug aus Einzelstempeln (G, R, H, S) zum Ausformen dieses Deckels wird vorgeschlagen.
