Description

Mit Schwächungslinien und Dichtungsscheiben versehene Flaschenkapsel Die Erfindung betrifft einen Flaschenverschluß. Es ist bekannt, Flaschenverschlüsse aus solchem Werkstoff herzustellen, daß se durch Strecken zum satten Anliegen an dem Flaschenhals gebracht werden können. Dieses Strecken, das es gestattet, sowohl eine Vergröberung des Metalls als auch ein vollkommen gleichmäßiges Glattziehen in dem unterhalb der Flaschenmündung befindlichen Teil geringeren Durchmessers zu erzielen, ist nur dann möglich, wenn die Kapsel in ihrer Fläche keine Unterbrechungen aufweist, zum mindesten nicht in dem Teil, der gedreht, gestreckt und im Durchmesser verringert werden muß. Durch die Anbringung der bekannten, zum Aufreißen der Kapsel dienenden Schwächungslinien würde aber eine solche Unterbrechung der Kapseloberfläche auftreten, welche während des Streckvorganges zum Bruch der Kapsel führt.Bottle cap with lines of weakness and sealing washers The invention relates to a bottle closure. It is known, bottle caps Manufacture from such a material that se by stretching to the full concern can be brought to the neck of the bottle. This stretching that allows both a coarsening of the metal as well as a perfectly even smoothing in the part of the smaller diameter located below the bottle mouth Achievement is only possible if the capsule has no interruptions in its area has, at least not in the part that is rotated, stretched and in diameter must be reduced. By attaching the known, to tear open the capsule Serving lines of weakness would, however, such an interruption of the capsule surface occur, which leads to breakage of the capsule during the stretching process.

Zur Vermeidung dieser Nachteile werden nun nach der Erfindung 'diese zum Aufreißen dienenden Schwächungslinien in dem unter der Flaschenmündung liegenden Kapselteil aufgebracht, nachdem die Metallkapsel auf dem Flaschenhals glattgestreckt worden ist. Die Zeichnung zeigt eine Flaschenkapsel gemäß der Erfindung.To avoid these disadvantages are now according to the invention 'these for tearing open weakening lines in the one below the bottle mouth Capsule part applied after the metal capsule is stretched smooth on the bottle neck has been. The drawing shows a bottle cap according to the invention.

Die Kapsel i wird nach ihrer Anbringung an dem Flaschenhals einer Streckung unterworfen, damit sie sich der Form des Halses derart anschmiegt, daß sie an allen Teilen der Halsfläche ohne Faltenbildung satt anliegt und eine vollkommen glatte Fläche aufweist, als ob sie ein angestrichener Lack wäre.The capsule i is after its attachment to the bottle neck a Subjected to stretching so that it conforms to the shape of the neck in such a way that it fits snugly on all parts of the neck surface without wrinkling and one perfectly has a smooth surface as if it were a painted varnish.

In der gestreckten Zone A-B werden nun, nachdem die Streckung vorgenommen worden ist, Stellen geringeren Widerstandes erzeugt, indem man z. B. den gestreckten Kapselteil mit kleinen Einschnitten 3 oder tiefen Scbraffierungen oder Durchlöcherungen oder sonstigen Markierungen versieht.In the stretched zone A-B, after the stretching is carried out has been generated, places of lower resistance by z. B. the stretched one Capsule part with small incisions 3 or deep scratches or perforations or other markings.
