Description

Selbsttätiger Tubenverschluß Die Erfindung betrifft einen Tubenverschluß, der sich durch Druck auf die Tube selbsttätig öffnet und der sich beim Drucknachlaß wieder schließt.Automatic tube closure The invention relates to a tube closure, which opens automatically when pressure is applied to the tube and which opens when the pressure is released closes again.

Die bekannten Schraubverschlüsse für Tuben, die zur Zeit dem Verbraucher hauptsächlich zur Verfügung stehen, haben folgende Nachteile: 1. Sie müssen ab- und wieder aufgeschraubt werden, wobei zwei Hände gebraucht werden. The well-known screw caps for tubes that are currently available to consumers mainly available, have the following disadvantages: 1. You have to and screwed back on, using two hands.

2. Unsauberkeit am Tubengewinde und Schraubverschluß, was auch beim Schieberverschluß zutrifft. 2. Uncleanliness on the tube thread and screw cap, which is also the case with Slider lock applies.

3. Der Schraubverschluß kann leicht verlorengehen. 3. The screw cap can easily be lost.

Durch den Tubendruck selbsttätig öffnende Verschlüsse sind in verschiedenen Ausführungen bekannt. There are different types of closures that open automatically due to the tube pressure Executions known.

Diese Verschlüsse weisen z. B. eine in dem Tubenkopf eingespannte, zwischen zwei Seitenwänden des Verschlusses geführte und gegen den Rand der Austrittsöffnung unter Vorspannung anliegende Blattfeder auf. Bei einer bekannten Ausführungsform kann der Anpreßdruck der Blattfeder durch Unterstützung in der Nähe des Randes der Austrittsöffnung erhöht werden. Weiterhin ist es auch bekannt, an Stelle der die Austrittsöffnung verschließenden Blattfeder eine schwenkbare Zunge vorzusehen, die mittels einer Blattfeder oder einer Schraubenfeder elastisch gegen den Rand der Austrittsöffnung gedrückt wird. Die bekannten selbsttätigen Verschlüsse sind entweder fest mit dem Tubenhals verbunden oder als getrennt aufschraubbares Verschlußteil hergestellt. Die bekannten selbsttätigen Verschlüsse weisen den Nachteil auf, daß der Anpreßdruck der die Austrittsöffnung verschließenden Zunge nicht regelbar ist.These closures have z. B. a clamped in the tube head, guided between two side walls of the closure and against the edge of the outlet opening leaf spring applied under pretension. In a known embodiment can reduce the contact pressure of the leaf spring by supporting near the edge of the Outlet opening can be increased. Furthermore, it is also known in place of the To provide a pivotable tongue that closes the outlet opening by means of a leaf spring or a helical spring elastically against the edge of the Outlet opening is pressed. The known automatic closures are either firmly connected to the tube neck or as a separately screwable closure part manufactured. The known automatic closures have the disadvantage that the contact pressure of the tongue closing the outlet opening cannot be regulated.

Der erfindungsgemäße Verschluß wird mit dem Innengewinde 4, welches dem Außengewinde einer Normaltube entspricht, auf die Tube geschraubt; es ist in der Hauptsache für Zahnpastatuben und ähnliche Tubenpasten, wie Schuhereme, Herdputzmittel, geeignet. Der Verschluß weist eine zwischen zwei Seitenwänden 1 geführte Blattfeder 2 auf, die sich gegen den Rand der Austrittsöffnung anlegt. The closure according to the invention is with the internal thread 4, which corresponds to the external thread of a normal tube, screwed onto the tube; it is in the main thing for toothpaste tubes and similar tube pastes, such as shoe items, stove cleaning agents, suitable. The closure has a leaf spring guided between two side walls 1 2, which rests against the edge of the outlet opening.

Von den bekannten automatischen Verschlüssen unterscheidet sich der erfindungsgemäße Verschluß dadurch, daß eine einstellbare Druckfeder3 vorhanden ist, welche die stufenlose Regelung des Anpreßdruckes der Blattfeder 2 gegen den Rand der Austrittsöffnung erlaubt. Die Einstellung der Druckfeder kann z. B. mittels einer Rändelschraube erfolgen. The differs from the known automatic closures closure according to the invention in that there is an adjustable compression spring3, which the stepless regulation of the contact pressure of the leaf spring 2 against the edge the outlet opening allowed. The setting of the compression spring can, for. B. by means of a knurled screw.

Diese einfache und stufenlose Regelbarkeit des Anpreßdruckes ist insofern von großer Bedeutung, als der Anpreßdruck der Blattfeder der Viskosität der jeweiligen Füllmasse angepaßt werden kann. This simple and stepless controllability of the contact pressure is insofar of great importance as the contact pressure of the leaf spring of the viscosity can be adapted to the respective filling compound.
