Description

Tubenverschlüsse sind gewöhnlich als kleine Hütchen ausgebildet, deren offenes Ende mit Innengewinde zum Aufschrauben auf das Gewinde der Tubenöffnung versehen ist. Diese Hütchen müssen vor dem Gebrauch der Tube abgeschraubt werden und können dann leicht verlorengehen. Um dies zu vermeiden, hat man Tubenverschlüsse konstruiert, die entweder nach einer Umdrehung die Austrittsöffnung freigeben oder bei Druck auf die Tube einen Mechanismus in Tätigkeit setzen, der den Tubeninhalt heraustreten läßt und sich bei Nachlassen des Druckes selbsttätig schließt. Die Fertigung solcher Tubenverschlüsse ist jedoch schwierig und ihre Wirkung nicht zuverlässig. Einen noch anderen Tubenverschluß hat man ohne t)ffnung hergestellt, jedoch an einer Stelle die Wandstärke besonders dünn gemacht, so daß die Wand bei der ersten Inbetriebnahme an dieser Stelle platzt und den Tubeninhalt freigibt. Die aufgeplatzte Stelle schließt jedoch später nicht ausreichend, so daß der Tubeninhalt dann dem Vertrocknen oder Verderben ausgesetzt ist. Tube closures are usually designed as small hats, its open end with internal thread for screwing onto the thread of the tube opening is provided. These caps must be unscrewed before using the tube and can then easily be lost. To avoid this, you have tube closures constructed, which either release the outlet opening after one turn or when pressure is applied to the tube, a mechanism is activated that controls the contents of the tube can emerge and closes automatically when the pressure drops. the However, the manufacture of such tube closures is difficult and their effect is not reliable. Another tube closure has been made without an opening, but on one Make the wall thickness extra thin so that the wall is when you first use it bursts at this point and releases the contents of the tube. The ruptured area closes but later not sufficient, so that the tube contents then dry up or Susceptible to spoilage.

Dieser Nachteil wird durch den erfindungsgemäßen Tubenverschluß vermieden. Der Tubenverschluß besteht nach der Erfindung aus einer auf die Tube aufschraubbaren Kappe, mindestens zum Teil aus dehnbarem Material, mit einem erhöhten Mittelstück und ist dadurch gekennzeichnet, daß das Mittelstück mit offenen, im Ruhezustand elastisch verschlossenen Durchbrüchen in Gestalt zweier rechtwinklig zueinander verlaufender Schlitze versehen ist. This disadvantage is avoided by the tube closure according to the invention. According to the invention, the tube closure consists of one that can be screwed onto the tube Cap, at least partly made of stretchable material, with a raised middle section and is characterized in that the middle piece with open, at rest elastically closed breakthroughs in the form of two at right angles to each other running slots is provided.

In den Abbildungen ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt und nachstehend beschrieben, ohne daß die Erfindung jedoch auf diese Ausführungsform beschränkt sein soll. An exemplary embodiment of the invention is shown schematically in the figures shown and described below, without the invention, however, on this Embodiment should be limited.

Fig. 1 zeigt einen erfindungsgemäßen Tubenverschluß im Querschnitt, Fig. 2 in der Draufsicht. Fig. 1 shows a tube closure according to the invention in cross section, Fig. 2 in plan view.

Die Offnung I der Tube 2 ist an den Seiten mit einem Gewinde 3 versehen, auf das der etwas konische Gewindeteil 4 aufgeschraubt ist. Der Gewindeteil 4 ist mit einem Dorn 5 aus elastischem Material, wie Gummi, oder einem elastischenKunststoff versehen, der oben von zwei rechtwinklig zueinander verlaufenden Einschnitten 6 und 7 durchbrochen ist. The opening I of the tube 2 is provided with a thread 3 on the sides, onto which the somewhat conical threaded part 4 is screwed. The threaded part 4 is with a mandrel 5 made of elastic material such as rubber or an elastic plastic provided, the top of two perpendicular incisions 6 and 7 is broken.

Der Gewindeteil 4 und der Dorn 5 können beide aus elastischem Material bestehen, jedoch kann der Gewindeteil 4 auch aus festem Material, wie Hartgummi oder Metall, angefertigt sein. The threaded part 4 and the mandrel 5 can both be made of elastic material exist, but the threaded part 4 can also be made of solid material, such as hard rubber or metal.

Beim Druck auf den Inhalt der Tube geben die zungenartigen Vorsprünge 8 nach, biegen sich nach außen und lassen einen Teil des Tubeninhaltes hindurch. Sobald der Druck auf den Tubeninhalt nachläßt, drücken die Zungen 8 sich gegeneinander, so daß der noch zwischen ihnen befindliche Tubeninhalt nach innen zurückgedrückt oder tach außen herausgequetscht wird. Die Tube ist dann wieder verschlossen und der Tubeninhalt äußeren Einwirkungen entzogen. pATENTANSPR8CHE: I. Tubenverschluß, mindestens zum Teil aus dehnbarem Material, der aus einem mit Gewinde versehenen Ring zum Aufschrauben auf die Tube und einem erhöhten Mittelstück besteht, dadurch gekennzeichnet, daß das Mittelstück mit offenen, im Ruhezustand elastisch verschlossenen Durchbrüchen in Gestalt zweier rechtwinklig zueinander verlaufender Schlitze versehen ist. When pressure is applied to the contents of the tube, the tongue-like protrusions appear 8 after, bend outwards and let part of the tube contents through. As soon as the pressure on the tube contents subsides, the tongues 8 press against each other, so that the contents of the tube still between them are pushed back inwards or is squeezed out on the outside. The tube is then closed again and the tube contents are withdrawn from external influences. PATENT CLAIMS: I. Tube closure, at least in part made of stretchable material, that of a threaded one Ring for screwing onto the tube and a raised center piece consists of this characterized in that the middle piece with open, elastically closed at rest Provided breakthroughs in the form of two slots running at right angles to one another is.
