Description

Die Erfindung betrifft den Verschluß von Flaschen oder ähnlichen Gefäßen mittels Kronenkorkens. Der Kronenkorkenverschluß ist allgemein bekannt. Ein napfförmiges, mit Kork oder anderem elastischen Material ausgefüttertes Blechstiick umgreift mit seinem gewellten Rand die Mündungswulst des Flaschenhalses, an welche der Rand des Kronen,-korkens auf seinem gesamten Umfang mittels eines konisch gebohrten Druckstückes angepreßt wird.The invention relates to the closure of bottles or similar vessels by means of Crown cap. The crown cap closure is well known. A cup-shaped, with Cork or other elastic material lined sheet metal piece embraced with its corrugated Edge of the mouth bulge of the bottle neck, to which the edge of the crown, cork pressed on its entire circumference by means of a conically drilled pressure piece will.

Diese Kronenkorkenverschlüsse sind billig, zuverlässig und hygienisch. Sie besitzen aber den Nachteil, daß sie schwer zu öffnen sind, selbst, wenn am Flaschenhals besondere, als Stützpunkt dienende Angüsse vorhanden sind, um das Abheben des Kronenkorkens mittels einer als Hebel dienenden Münze zu erleichtern. Im allgemeinen bedarf es besondererThese crown caps are cheap, reliable and hygienic. But you own the disadvantage that they are difficult to open, even if special on the bottle neck, as Base serving sprues are available to lift the crown cap by means of a coin serving as a lever. In general, it needs special ones

ao Öffner, um Kronenkorken der üblichen Form ohne Schwierigkeiten abheben zu können,. Man hat deshalb auch vorgeschlagen, besondere Ohren oder Vorsprünge am Kronenkorkenrand anzuordnen, um so das Abhebenao opener to be able to lift off crown corks of the usual shape without difficulty. It has therefore also been proposed to have special ears or protrusions on the edge of the crown cap to arrange so as to take off

as zu erleichtern. Solche Spezialausbildungen verteuern aber den Verschluß und sind vor allem nicht überall käuflich, wie dies bei den Kronenkorken der üblichen Form der Fall ist.as to facilitate. Such special training but increase the price of the closure and, above all, are not available for sale everywhere, as is the case with the Crown cap of the usual shape is the case.

Die vorliegende Erfindung bezweckt einen Flaschenverschluß unter Verwendung von Kronenkorken der üblichen Urform zu schaffen, der auch leicht, beispielsweise mittels einer Münze geöffnet werden kann, ohne daß am Kronenkorken besondere Ohren oder Vorsprünge vorgesehen sind, und ohne daß besondere Öffner benutzt werden müßten.The present invention aims at a bottle closure using crown corks to create the usual archetype, which can also be opened easily, for example by means of a coin, without the Crown corks special ears or protrusions are provided, and without that special Opener would have to be used.

Dies wird erfindungsgemäß bei dem neuen Kronenkorkenverschluß dadurch erreicht, daß bei dem auf die Mündung einer Flasche aufgeklemmten Kronenkorken der üblichen Urform eine oder mehrere Gruppen von Zacken des Kapselrandes von der Mündungswulst des Flaschenhalses abstehen.This is achieved according to the invention in the new crown cork closure in that with the crown cork of the usual archetype clamped onto the mouth of a bottle one or more groups of spikes on the edge of the capsule protrude from the bead of the mouth of the bottle neck.

Zur Herstellung dieser Kronenkorkenverschlüsse mit einzelnen abstehenden Zackengruppen kann erfindungsgemäß so verfahren werden, daß der Anpreßdruck des Drückstempels auf die Zacken so ausgeübt wird, daß eine oder mehrere Zackengruppen hiervon nicht betroffen werden.For the production of these crown cork closures with individual protruding groups of prongs can be proceeded according to the invention so that the pressure of the pressure ram is exerted on the prongs that one or more groups of peaks are not affected by this.

Hierzu dient beispielsweise ein Drückstempel, welcher in üblicher Weise konisch gebohrt ist, aber auf einem Teil seines inneren .Umfanges mit einer Ausnehmung versehen ist oder einen entsprechenden Schlitz aufweist. Die Ausnehmung kann sich beispielsweise etwa über ein Viertel des Bohrungsumfanges erstrecken, so daß mittels eines solchen Drückstempels nur drei Viertel des Kronenkorkenrandes dicht gegen die Randwulst des Flaschenhalses gepreßt werden, während das übrige Viertel des Randes so weit abstehen bleibt, daß der Kronenkorken durch eine unter die abstehenden Zacken gepreßte Münzie leichtFor example, a pressure ram, which is drilled conically in the usual way, is used for this purpose is, but is provided with a recess on part of its inner .Umfanges or has a corresponding slot. The recess can, for example extend approximately over a quarter of the circumference of the bore, so that by means of such a push ram only three quarters of the crown cork edge is pressed tightly against the bead of the bottle neck, while the the remaining quarters of the edge stick out so far that the crown cork passes through an underneath the protruding prongs pressed coin lightly

Claims

480720 can be lifted. Tests have shown that it is sufficient for the complete and reliable sealing of the new crown cork closure if a little more than half of the edge of the capsule is pressed tightly. For greater "security, however, in the embodiments according to the present invention, three quarters or even more of the crown cork edge are generally pressed tightly. To explain the invention, the drawing illustrates an exemplary embodiment for fastening the new capsule closure device. for clamping crown caps according to the present invention in a perspective view. jFig. 2 is a vertical section through the same punch To attach the latter to your bottle neck is provided with a recess G. When the crown cork is pressed on by means of the stamp shown, a group of prongs of the crown cork edge corresponding to the recess Q protrudes from the mouth bulge of the bottle neck To facilitate the opening of the new crown cork closure by means of a coin reaching under the stealing group of prongs, bottles can be used with sprues or other projections provided on their neck in a manner known per se, which serve as a support point for the coin acting as a lever. In certain cases, the pressure piece that clamps the crown cork can also be equipped with a special, movable countersink, which corresponds to the recess in the throat of the pressure piece, in order to press the cork disc in the crown cork firmly against the bottle mouth at the point where a group of prongs of the crown cork edge remains. It has been found, however, that this precautionary measure is generally unnecessary. (Instead of a group of protruding prongs, several groups of edge prongs can protrude from the new crown cork closure, provided this is compatible with the tightness of the closure . P ΑΤΕΝϊ claims:

1. The usual crown cork clamped onto the mouth of a bottle or the like Original shape, characterized in that one or more groups of prongs of the The edge of the capsule protrudes from the bead of the mouth of the bottle neck.

2. Method for pressing on crown corks clamped on according to claim 1 on bottles, characterized in that the contact pressure on the prongs is exercised in such a way that one or more groups of prongs are not affected.
