Description
Aus Cellulosederivaten bestehender Überzug für Dichtungsscheiben von Flaschenverschlüssen. Bei Flaschenverschlüssen mit Metallkapseln, wie z. B. bei dem weitverbreiteten Kronkork, bestehen die Dichtungsscheiben aus Kork. Ein vollkommenes Dichtungsmaterial ist Korlc indessen aus vielen Gründen durchaus nicht. Abgesehen von dem zuweilen auftretenden Korkgeschmack bestehen die Nachteile in ungleichmäßigem Material, den Poren und dem Umstande, daß die Korkrinde nicht dick genug ist, um sie in die für den Fabrikationsgang geeignete Form zu bringen. Ferner dringt nach dem Verschließen der Flasche durch die Poren der Korkscheibe Feuchtigkeit bis zur Metallkapsel durch. Deshalb muß zwischen Kork und Metall eine besondere Zwischenlage aus wasserdichtem Stoff, in der Regel paraffiniertem Papier, Harzpapier oder Stanniol eingelegt werden. Man hat bereits vorgeschlagen, zur Beseitigung dieser Übelstände die Korkscheiben mit einem Überzug aus reiner Dinitrocellttlose zu versehen oder Holzscheiben mit diesem Überzug zu verwenden. Die geringe Dehnbarkeit und Sprödigkeit solcher Überzüge hat indessen ihre Anwendung vereitelt. Auch die Verwendung von Faserstoffen statt Kork ist an den bisher vorgeschlagenen ungeeigneten Überzügen gescheitert.Coating consisting of cellulose derivatives for sealing washers from Bottle caps. In the case of bottle closures with metal capsules, such as B. at the widespread crown cork, the sealing washers are made of cork. A perfect one For many reasons, however, Korlc is by no means a sealing material. Apart from that The disadvantages of the occasional cork taste are that it is uneven Material, the pores and the fact that the cork bark is not thick enough to to bring them into the form suitable for the production process. Further penetrates closing the bottle through the pores of the cork disc moisture up to Metal capsule through. Therefore, a special intermediate layer must be placed between the cork and the metal Made of waterproof fabric, usually paraffin paper, resin paper or tinfoil be inserted. It has already been suggested to remedy this evil to provide the cork discs with a coating of pure dinitrocellulose or Use wooden discs with this coating. The low ductility and brittleness however, such coatings have prevented their application. Also the use of Fibers instead of cork are the unsuitable coatings proposed so far failed.
Gemäß der Erfindung werden derartige Dichtungsscheiben aus Faserstoffen, wie beispielsweise Pappe, mit einer hochelastischen Haut überzogen, die durch die Scheibe gegen die Zündung der Flasche gepreßt wird. Diese Haut besteht beispielsweise aus Nitrocellulose, die durch Zusatz von nicht flüchtigen Gelatiniermitteln die erforderliche Elastizität, Dehnbarkeit und Schmiegsamkeit erhalten hat. Die so hergestellte filmartige Haut, die auf der Scheibe aus Faserstoff fest angebracht sein kann, besitzt nun alle Eigenschaften, um sich vollkommen fest und dicht jeder Unebenheit der Flaschenmündung anzuschmiegen, ohne zu zerreißen. Hierdurch gelingt es, die Flaschen hermetisch zu verschließen, und zwar so, daß deren Inhalt nur mit dem Glase und der elastischen Haut in Berührung kommt. Als brauchbare, nicht flüchtige Gelatiniermittel kommen alle die bekannten Kampferersatzmittel in Frage, soweit sie sich für den genannten Zweck eignen, Lösungsvermögen für Celluloseester besitzen, geruch- und geschmacklos sind. Als Beispiel sei auf die verschiedenen Phthals.äureester und Essigsäureester verwiesen.According to the invention, such sealing washers are made of fibrous materials, such as cardboard, covered with a highly elastic skin that is covered by the Disc is pressed against the ignition of the bottle. This skin exists, for example made of nitrocellulose, which by adding non-volatile gelatinizing agents the required elasticity, ductility and pliability. The one made in this way film-like skin, which can be firmly attached to the pulp made of fiber material, possesses now all the properties in order to be perfectly firm and tight against every unevenness of the bottle mouth to fit without tearing. This makes it possible to hermetically seal the bottles to close, in such a way that their contents only with the glass and the elastic Comes into contact with skin. Come as useful, non-volatile gelling agents all the known camphor substitutes in question, insofar as they are in favor of the said Suitable for the purpose, have solvent power for cellulose esters, odorless and tasteless are. As an example, consider the various phthalic acid esters and acetic acid esters referenced.
