Description

Es sind Schraubkapselverschlüsse für Flaschen mit Außengewinde und einer in der Schraubkapsel angeordneten, den Flaschenhals auch mit einem Rand seitlich umfassenden Dichtungskappe bekannt. Diese Schraubkapselverschlüsse haben den Nachteil, daß der dicke, umlaufende Rand der Dichtungskappe den Eingriff in ein verjüngtes Ende des Flaschenhalses erforderlich macht. Diese Schraubkapselverschlüsse eignen sich daher nicht zur Anwendung bei Flaschen mit' nicht verjüngtem Ende des Flaschenhalses, wie sie allgemein im Gebrauch sind. Abgesehen davon bedingt die Anwendung dieser Schraubkapselverschlüsse für jede Flaschenhalsweite eine besonders bemessene Dichtungskappe, die mit ihrem inneren Durchmesser dem verjüngten Ende des Flaschenhalses, mit ihrem äußeren Durchmesser dem inneren Durchmesser der Verschlußkapsel angepaßt ist. Hierdurch sind im Hinblick auf die vorhandenen unterschiedlichen Flaschengrößen auch Dichtungskappen notwendig, die der jeweiligen Flaschenhalsgröße entsprechen müssen, was in wirtschaftlicher Beziehung als erheblicher Nachteil anzusehen ist. They are screw caps for bottles with an external thread and one arranged in the screw cap, the bottle neck also with an edge on the side comprehensive sealing cap known. These screw caps have the disadvantage that the thick, circumferential edge of the sealing cap engages in a tapered Requires the end of the bottle neck. These screw caps are suitable therefore not suitable for use with bottles with a 'non-tapered end of the bottle neck, as they are commonly in use. Apart from that, the application requires this Screw cap closures for each bottle neck width a specially dimensioned sealing cap, those with their inner diameter the tapered end of the bottle neck, with their outer diameter is adapted to the inner diameter of the closure capsule. Through this are also sealing caps in view of the different bottle sizes available necessary, which must correspond to the respective bottle neck size, which in economic Relationship is to be regarded as a significant disadvantage.

Die Erfindung hilft diesen Mängeln der bekannten Schraubkapselverschlüsse ab. Sie betrifft einen Schraubkapselverschluß für Flaschen und flaschenähnliche Behälter mit Außengewinde und einer in der mit einem Vorsprung versehenen Schraubkapsel angeordneten, auf das unverjüngte Flaschenhalsende auftreffenden Dichtungsscheibe, und die Erfindung besteht darin, daß der Vorsprung der Schraubkapsel zwecks Bildung einer abschnürenden Abdichtung der Dichtungsscheibe als Kegelstumpf ausgebildet ist, dessen größter Durchmesser etwa dem Innendurchmesser des Flaschenhalses entspricht. The invention remedies these shortcomings of the known screw cap closures away. It relates to a screw cap closure for bottles and bottle-like ones Container with external thread and one in the screw cap provided with a projection arranged sealing washer that hits the untapered end of the bottle neck, and the invention consists in that the projection of the screw cap for the purpose of formation a constricting seal of the sealing washer designed as a truncated cone is, whose largest diameter corresponds approximately to the inner diameter of the bottle neck.

In der Zeichnung ist der erfindungsgemäße Schraubkapselverschluß an einer Flasche imLängsschnitt veranschaulicht; Abt. ? zeigt einen der Abb. 1 entsprechenden Schnitt durch die Verschlußkappe allein. In the drawing is the screw cap according to the invention illustrated on a bottle in longitudinal section; Dept.? shows one of Fig. 1 corresponding Section through the cap alone.

I ist der obere Teil einer Flasche, die an ihrem Halse in bekannter Weise mit Außengewinde versehen ist. 3 ist die in bekannter Weise mit Innengewinde versehene Verschlußkapsel, die an ihrem Boden 4 mit einem nach innen vortretenden, als Kegelstumpf 6 (Abb. 2) ausgebildeten Vorsprung 5 versehen ist, dessen größter Durchmesser etwa dem Innendurchmesser des Flaschenhalses entspricht. I is the top of a bottle that is on its neck in well known Way is provided with external thread. 3 is the one in a known manner with an internal thread provided closure capsule, which at its bottom 4 with an inwardly protruding, as a truncated cone 6 (Fig. 2) formed projection 5 is provided, the largest of which Diameter roughly corresponds to the inside diameter of the bottle neck.

Die elastische Dichtungsscheibe 7 (Abb. I) legt sich nicht nur, wie dies bei den bekannten Abdichtungen der Fall ist, beim Zuschrauben der Verschlußkapsel 3, 4 eben abdichtend auf die Stirnfläche des unverjüngten Flaschenhalses 2, sondern sie führt darüber hinaus auch eine einschnürende Abdichtung an der kegeligen Ringfläche 7' zwischen dem Vorsprung 5 und der Flaschenhals-Stirnfläche herbei. Vermöge dieser besonderen Wirkung des Verschlusses wird jegliches ungewollte Austreten des öl- oder sirupartigen, mehr oder weniger flüssigen Flascheninhalts bei geschlossener Flasche auf einfachste Weise erfolgreich verhindert.The elastic sealing washer 7 (Fig. I) does not just lie down, like this is the case with the known seals when the closure capsule is screwed on 3, 4 just sealingly on the end face of the untapered bottle neck 2, but it also leads to a constricting seal on the conical ring surface 7 'between the projection 5 and the bottle neck end face. Fortune of this the special effect of the closure prevents any unwanted leakage of the oil or syrupy, more or less liquid bottle contents when the bottle is closed Bottle successfully prevented in the simplest way.

PATEXTANSPEECII Schraubkapselverschluß für Flaschen und flaschenähnliche Behälter mit Außengewinde und einer in der mit einem Vorsprung versehenen Schraubkapsel angeordneten, auf das Flaschenhalsende auftreffenden Dichtungsscheibe, dadurch gekennzeichnet, daß der Vorsprung (5) zwecks Bildung einer abschnürenden Abdichtung der Dichtungsscheibe (7) als Kegelstumpf (6) ausgebildet ist, dessen größter Durchmesser etwa dem Innendurchmesser des unverjüngten Flaschenhalses (2) entspricht. PATEXTANSPEECII screw cap for bottles and similar bottles Container with external thread and one in the screw cap provided with a projection arranged sealing washer impinging on the bottle neck end, characterized in that that the projection (5) for the purpose of forming a constricting seal of the sealing washer (7) is designed as a truncated cone (6), the largest diameter of which is approximately the inner diameter of the untapered bottle neck (2).
