Description

Die Erfindung betrifft ein Garantieverschlusssystem für ein Behältnis, insbesondere für eine Tube, dessen Auslassöffnung im Auslieferungszustand mit einer Versiegelung versehen ist und durch eine Verschlusseinrichtung verschließbar ist, die eine Hilfseinrichtung trägt, mittels derer die Versiegelung beim ersten Gebrauch geöffnet werden kann.The invention relates to a guarantee closure system for a container, in particular for a tube, the outlet opening is provided in the delivery state with a seal and can be closed by a closure device which carries an auxiliary device by means of which the seal can be opened during the first use.

Derartige Verschlüsse sind im Stand der Technik hinlänglich bekannt und werden in großer Verbreitung beispielsweise zum Verschließen von Behältnissen mit hygienischen, kosmetischen oder pharmazeutischen Produkten eingesetzt, bei denen die Manipulationssicherheit der Verschlüsse eine wichtige Anforderung darstellt.Such closures are well known in the art and are widely used, for example, for sealing containers with hygienic, cosmetic or pharmaceutical products, in which the tamper resistance of the closures represents an important requirement.

Eine der im Stand der Technik bekannten Arten zur Versiegelung von Behältnissen, insbesondere Tuben, sieht die Verwendung von Folien oder Plättchen vor, die auf die Auslassöffnungen der Behältnisse z. B. aufgeklebt sind. Bei der ersten Verwendung der Behältnisse müssen die Folien oder Plättchen von Hand durch den Verbraucher entfernt werden. Das bedarf eines gewissen Geschicks, da die Plättchen nicht immer einfach zu ergreifen sind. Ferner ergibt sich das hygienische Risiko, dass Bakterien und Keime von der Hand auf den Verschluss und somit auf den Inhalt der Tube übertragen werden. Ein weiterer Nachteil ist, dass das so abgezogene Garantiesiegel als Abfallprodukt anfällt.One of the known in the art for sealing containers, in particular tubes, provides for the use of films or platelets, which are on the outlet openings of the containers z. B. are glued. When using the containers for the first time, the foils or plates must be removed by the consumer by hand. This requires a certain amount of skill, as the tiles are not always easy to grab. Furthermore, there is the hygienic risk that bacteria and germs are transferred by hand to the closure and thus to the contents of the tube. Another disadvantage is that the warranty seal thus deducted is a waste product.

Ein anderes bekanntes Verschlusssystem ist, wie beispielsweise in der US 4,688,703 und der WO 2004/043816 A1 dargestellt, so konstruiert, das zum Entfernen der Versiegelung die Verschlusskappe geöffnet, gewendet und als Werkzeug zum Abdrehen des Versiegelungselements verwendet wird. Die Durchführung dieses Vorgangs erfordert ein gewisses Maß an technischem Verständnis und motorischem Geschick, was in den erwähnten Schriften als Vorteil zu Gunsten der Kindersicherheit beschrieben wird, beispielsweise jedoch für ältere Menschen oft ein schwieriges Hindernis darstellen kann.Another known closure system is, as in the US 4,688,703 and the WO 2004/043816 A1 shown, designed to remove the seal, the cap is opened, turned and used as a tool for turning off the sealing element. Carrying out this process requires a degree of technical understanding and motor skill, which is described in the cited documents as an advantage in favor of child safety, but may often be a difficult obstacle for the elderly, for example.

Eine andere technische Lösung beschreibt beispielsweise die DE 26 53 993 A1 vor. Darin wird ein Verschlusssystem dargestellt, bei dem das Entfernen der Versiegelung während des ersten Öffnens der Verschlusskappe erfolgt, ohne dass ein separater Schritt zum Öffnen der Versiegelung durchgeführt wird. Nachteilig an dieser Konstruktion ist jedoch, dass der Verbraucher bei geschlossenem Deckel nicht erkennen kann, ob eine Verletzung des Garantiesiegels vorliegt. Insbesondere ist es hierbei auch möglich, dass die Versiegelung versehentlich geöffnet wird.Another technical solution describes, for example, the DE 26 53 993 A1 in front. It shows a closure system in which the removal of the seal during the first opening of the cap takes place without a separate step to open the seal is performed. A disadvantage of this construction, however, is that the consumer can not recognize when the lid is closed, whether there is a violation of the warranty seal. In particular, it is also possible that the seal is opened accidentally.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein Garantieverschlusssystem zu schaffen, das die oben genannten Nachteile des Standes der Technik beseitigt und ein hohes Maß an Bedienkomfort und Inhaltsschutz bietet.The present invention is based on the object to provide a guarantee closure system which overcomes the above-mentioned disadvantages of the prior art and offers a high level of ease of use and content protection.

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Anspruchs 1 gelöst. Zu bevorzugende Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the subject matter of claim 1. Preferred developments of the invention are the subject of the dependent claims.

Das erfindungsgemäße Garantieverschlusssystem löst die gestellte Aufgabe dadurch, dass es zum Öffnen der mit einem Versiegelungselement versiegelten Auslassöffnung eine Hilfseinrichtung vorsieht. Diese Hilfseinrichtung ist der Verschlusseinrichtung zugeordnet, mit der das Behältnis auch im Gebrauchszustand verschließbar ist. Durch die Hilfseinrichtung wird im Auslieferungszustand des Verschlusses eine Rotationskraft auf das Versiegelungselement aufgebracht, die zum Öffnen der Versiegelung führt. Dabei wird der Verschluss vom Auslieferungszustand in den Gebrauchszustand überführt, was durch die Hilfseinrichtung selbst angezeigt wird und es dem Benutzer erlaubt, den Status der Versiegelung auch dann zu erkennen, wenn das Behältnis mit der Verschlusseinrichtung verschlossen ist.The guarantee closure system according to the invention achieves the stated object by providing an auxiliary device for opening the outlet opening sealed with a sealing element. This auxiliary device is associated with the closure device with which the container is also in the Use state is closed. By the auxiliary device, a rotational force is applied to the sealing element in the delivery state of the closure, which leads to the opening of the seal. In this case, the closure is transferred from the delivery state into the use state, which is indicated by the auxiliary device itself and allows the user to recognize the status of the seal even when the container is closed with the closure device.

Die Kraftübertragung der Hilfseinrichtung auf das Versiegelungselement erfolgt durch Formschluss. In einer bevorzugten Ausführungsform erfolgt die Kraftübertragung der Hilfseinrichtung auf das Versiegelungselement durch eine Kombination von Form- und Kraftschluss.The power transmission of the auxiliary device to the sealing element is effected by positive locking. In a preferred embodiment, the power transmission of the auxiliary device takes place on the sealing element by a combination of positive and non-positive.

Das Versiegelungselement weist vorzugsweise an seiner Oberseite eine Vertiefung auf, die im Auslieferungszustand des Verschlusses in Richtung der Hilfseinrichtung weist.The sealing element preferably has on its upper side a recess, which points in the delivery state of the closure in the direction of the auxiliary device.

Dabei kann die Vertiefung im wesentlichen einen Innenumriss aufweisen, der eine Form haben kann, die aus einer Gruppe von Formen ausgewählt ist, die ein Dreieck, ein Viereck, ein Fünfeck, ein Sechseck oder ein N-Eck mit beliebiger Zahl von N aufweist, wobei diese Formengruppe auch eine elliptische, ovale oder sonst wie mit einer gekrümmten Außenlinie gebildete Struktur aufweisen kann.In this case, the recess may substantially have an inner contour, which may have a shape which is selected from a group of shapes having a triangle, a quadrangle, a pentagon, a hexagon or an N-corner with any number of N, wherein This group of forms may also have an elliptical, oval or otherwise formed as with a curved outer line structure.

Die Außenfläche des Versiegelungselements weist vorzugsweise eine im wesentlichen zylindrische Form auf.
