Description

Selbsttätiger Tubenverschluß Tubenverschlüsse, die sich durch Druck auf die Tube selbsttätig öffnen und die sich beim Drucknachlaß wieder schließen, sind in verschiedenen Ausführungen bekannt. 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.Automatic tube closure Tube closures that are opened by pressure open automatically on the tube and close again when the pressure is released, are known in various designs. These closures have z. Legs clamped in the tube head, guided between two side walls of the closure and leaf spring resting against the edge of the outlet opening under pretension on. In a known embodiment, the contact pressure of the leaf spring can through Support near the edge of the outlet opening can be increased. Farther it is also known instead of the leaf spring closing the outlet opening to provide a pivotable tongue, which by means of a leaf spring or a helical spring is pressed elastically against the edge of the outlet opening. The well-known automatic ones Closures are either firmly connected to the neck of the tube or can be screwed on separately Closure part made.

Die bekannten selbsttätigen Verschlüsse dieser Art weisen den Nachteil auf, daß der Anpreßdruck der die Austrittsöffnung verschließenden Zunge nicht regelbar ist. Nach einem älteren Vorschlag ist der Anpreßdruck der Blattfeder bei einem derartigen Verschluß mittels einer Druckfeder regulierbar. Demgegenüber wird bei dem erfindungsgemäßen Verschluß der Anpreßdruck der Blattfeder durch eine direkt auf diese wirkende Rändelschraube verändert. The known automatic closures of this type have the disadvantage on that the contact pressure of the tongue closing the outlet opening cannot be regulated is. According to an older proposal, the contact pressure of the leaf spring is such Closure adjustable by means of a pressure spring. In contrast, in the inventive Closure of the contact pressure of the leaf spring by a knurled screw acting directly on it changes.

Der erfindungsgemäße Verschluß wird mit dem Innengewinde4, welches dem Außengewinde einer Normaltube entspricht, auf die Tube geschraubt; es ist in der Hauptsache für Zahnpastatuben, Nahrungsmitteltuben und ähnliche Tubenpasten, wie Schuhcreme, 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 thread4, which corresponds to the external thread of a normal tube, screwed onto the tube; it is in the main thing for toothpaste tubes, food tubes and similar tube pastes, such as shoe polish, stove cleaning agent, are suitable. The closure has one between two Side walls 1 guided leaf spring 2, which is against the edge of the outlet opening applies.

Von den bekannten automatischen Verschlüssen unterscheidet sich der erfindungsgemäße Verschluß dadurch, daß eine einstellbare Rändelschraube 3 vor- handen ist, welche die stufenlose Regelung des Anpreßdruckes der Blattfeder 2 gegen den Rand der Austrittsöffnung erlaubt. The differs from the known automatic closures Closure according to the invention characterized in that an adjustable knurled screw 3 is provided act is which the stepless regulation of the contact pressure of the leaf spring 2 against the Edge of the outlet opening allowed.

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.
