Description

Verschluss eines BehältersClosure of a container

Die Erfindung betrifft einen Verschluss eines Behälters mit einem mit dem Behälter verbundenen Stutzen, dessen Ausgießöffnung durch eine Kunststoff- Verschlusskappe verschlossen ist, die mit ihrem Rand den Stutzen außen übergreift.The invention relates to a closure of a container with a nozzle connected to the nozzle, the pouring spout is closed by a plastic closure cap, which engages over the outside with its edge.

Es sind die unterschiedlichsten Kappenverschlüsse für Behälterstutzen bekannt. Hierbei werden aufwendige Konstruktionen benutzt, um sicherzustellen, dass ein unbefugtes vorheriges öffnen nicht erfolgt ist. Es werden dabei insbesondere Abreißlaschen und Abreißringe verwendet, die ein vorheriges Öffnen anzeigen.There are a variety of cap closures for container neck known. In this case, elaborate constructions are used to ensure that an unauthorized previous opening was not done. In particular, tear-off tabs and tear-off rings are used which indicate a previous opening.

Aufgabe der Erfindung ist es, einen Verschluss der eingangs genannten Art so zu verbessern, dass er bei einfachster Konstruktion und wenig Einzelteilen ein unbefugtes vorheriges Öffnen aufzeigt und hierbei eine hohe Dichtigkeit, einen sicheren Halt und eine Wiederverschließbarkeit gewährleistet.The object of the invention is to improve a closure of the type mentioned so that it shows the simplest construction and few items unauthorized prior opening and this ensures a high density, a secure fit and resealability.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der innere Kappenboden von einer Kunststofffolie bedeckt ist, die am Kappenboden unlösbar befestigt ist, und dass bei aufgesetzter Kappe die Folie auf dem oberen Rand des Stutzens aufgeschweißt ist, wobei die flüssigkeits- und gasdichte Schweißverbindung beim Abschrauben der Kappe lösbar ist. Bei einem solchen Verschluss erzeugt ein Abnehmen der Verschlusskappe ein Abreißen der Stutzenoberseite von der Folie, wobei dieses Abreißen einen zusätzlichen Kraftaufwand erfordert, der nach einem Zweitverschließen nicht mehr nötig ist, so dass der Benutzer beim Abnehmen der Kappe erkennen kann, ob er als Erster den Behälter öffnet. Hierbei ist die Konstruktion in Herstellung und Benutzung besonders einfach.This object is achieved in that the inner cap base is covered by a plastic film, which is permanently attached to the cap base, and that with the cap attached the film is welded to the upper edge of the nozzle, wherein the liquid and gas-tight welded joint when unscrewing the Cap is detachable. In such a closure, a removal of the cap produces a tearing of the nozzle top of the film, this tearing requires additional force, which is no longer necessary after a second closure, so that the user can recognize when removing the cap, whether he is the first Container opens. Here, the construction in production and use is particularly simple.

Eine besonders einfache Herstellung ist dann gegeben, wenn die Folie in die Kappe durch ein Inmould-Verfahren beim Kunststoffspritzen der Kappe eingebracht ist. Auch ist hierbei von Vorteil, wenn Stutzenrand und Folie durch Ultraschallschweißen miteinander verbunden sind.A particularly simple production is given when the film is introduced into the cap by an in-mold process during plastic injection of the cap. It is also advantageous if the nozzle edge and film are connected to each other by ultrasonic welding.

Vorzugsweise wird vorgeschlagen, dass an der Innenwand des Kappenrandes mindestens ein insbesondere ringförmiger Vorsprung insbesondere Wulst vorsteht, der unter mindestens einem insbesondere ringförmigen Vorsprung an der Außenseite des Stutzens liegt. Damit ist die Kappe allein durch ein Aufdrücken (Aufprellen) verschließbar. Alternativ kann aber auch die Kappe durch Aufschrauben befestigt und durch Abschrauben lösbar sein.Preferably, it is proposed that on the inner wall of the cap edge at least one in particular annular projection in particular bead protrudes, which lies under at least one particular annular projection on the outside of the nozzle. Thus, the cap is closed by pressing (bouncing) alone. Alternatively, however, the cap can be attached by screwing and detachable by unscrewing.

Auch wird vorgeschlagen, dass die Folie mindestens ein elektronisches Bauteil insbesondere Datenspeicher aufweist. Hierdurch kann die Kappe zusätzliche Funktionen übernehmen und insbesondere Informationen über den Inhalt und dessen Zustand als auch über den Zustand des Verschlusses abgeben.It is also proposed that the film has at least one electronic component, in particular data memory. In this way, the cap can take on additional functions and in particular deliver information about the content and its condition as well as about the state of the closure.

Besonders vorteilhaft ist es, wenn innerhalb der Kunststofffolie eine Metallfolie insbesondere eine Aluminiumfolie liegt, die beidseitig mit Kunststoff kaschiert ist. Hierdurch kann in der metallenen Zwischenschicht Wärme induziert werden, um die zwei Kunststoffaußenseiten an Kappe und Stutzen anzuschweißen bzw. anzuschmelzen.It is particularly advantageous if, within the plastic film, a metal foil, in particular an aluminum foil, is laminated on both sides with plastic. As a result, heat can be induced in the metal intermediate layer in order to weld or melt the two plastic outer sides on the cap and neck.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in einem axialen Schnitt dargestellt und wird im folgenden näher beschrieben. An einem Behälter 1 ist an der Oberseite ein Stutzen 2 aus Kunststoff angeformt, der mit seinem oberen Rand 3 eine Ausgießöffnung 4 bildet. Auf den Stutzen 2 ist eine Verschlusskappe 5 aufdrückbar, wobei die Verschlusskappe 5 mit ihrem insbesondere zylindrischen Rand 6 den Stutzen außen übergreift. Ein sicherer Halt der Kappe 5 am Stutzen 2 ist dadurch gegeben, dass an der Innenwand des Randes 6 ein ringförmiger innerer Vorsprung 7 vorsteht, der über einen äußeren Vorsprung 8 an der Außenseite des Stutzens 2 schiebbar ist, so dass der Vorsprung 7 unter dem Vorsprung 8 einrastet.An embodiment of the invention is illustrated in the drawing in an axial section and will be described in more detail below. On a container 1, a nozzle 2 made of plastic is formed on the upper side, which forms a pouring opening 4 with its upper edge 3. On the nozzle 2, a cap 5 can be pushed, the cap 5 engages with its particular cylindrical edge 6 the nozzle outside. A secure hold of the cap 5 on the nozzle 2 is given by the fact that on the inner wall of the rim 6, an annular inner projection 7 projects, which is slidable over an outer projection 8 on the outside of the nozzle 2, so that the projection 7 under the projection 8 locks in place.

Der innere Kappenboden 5a der Verschlusskappe 5 ist von einer Kunststofffolie 9 als Siegelfolie bedeckt, die am Kappenboden unlösbar befestigt ist durch ein Inmould-Verfahren während der Spritzgießherstellung der Kappe 5 aus Kunststoff. Hierbei besteht die Folie 9 aus einem Kunststoff, der mit dem Kunststoff des Stutzens 2 verschweißbar ist.The inner cap bottom 5a of the cap 5 is covered by a plastic film 9 as a sealing film, which is permanently attached to the cap base by an in-mold process during injection molding of the cap 5 made of plastic. In this case, the film 9 consists of a plastic which is welded to the plastic of the nozzle 2.

Während oder nach des Aufdrückens der Verschlusskappe 5 auf den Stutzen 2 wird der Stutzenrand 3 mit der Folie 9 durch Induktionsschweißen verbunden. Hierzu weist die insbesondere dreischichtige Folie 9 eine mittlere Schicht aus Metallfolie insbesondere aus Aluminiumfolie auf. Wird der Verschluß in ein elektromagnetisches Wechselfeld gebracht, so wird dieDuring or after the pressing of the cap 5 on the nozzle 2, the nozzle edge 3 is connected to the film 9 by induction welding. For this purpose, the particular three-layer film 9 has a middle layer of metal foil, in particular of aluminum foil. If the shutter is placed in an alternating electromagnetic field, the

Metallschicht/Aluminiumschicht erwärmt und damit auch die Kunststoffschichten erwärmt und angeschweißt.Metal layer / aluminum layer heated and thus heated and welded to the plastic layers.

Wird die Verschlusskappe 5 vom Stutzen 2 durch Kraftaufwendung abgenommen, so bleibt die Folie 9 weiterhin fest am Boden der Kappe 5, da die Verbindung zwischen Folie 9 und Kappe 5 unlösbar ist. Dagegen reißt die Schweißverbindung zwischen dem Stutzenrand 3 und der Folie 9 auf.If the cap 5 is removed from the nozzle 2 by application of force, the film 9 remains firmly on the bottom of the cap 5, since the connection between the film 9 and 5 cap is insoluble. In contrast, the welded connection between the nozzle edge 3 and the film 9 breaks.

In und/oder auf der Folie 9 ist mindestens ein elektronisches, nicht dargestelltes Bauteil insbesondere ein Datenspeicher befestigt, dem verschiedene Aufgaben zukommen können. So kann dieses Bauteil aufzeigen, ob die Verschlusskappe bereits vorher einmal abgenommen worden ist. Hierzu ist dann dafür gesorgt, dass eine erstmalige Abnahme der Kappe 5 vom Rand 3 eine Leitung oder ein Bauteil so verändert, dass dies vom elektronischen Bauteil wahrgenommen bzw. dargestellt wird. Ferner kann das elektronische Bauteil Informationen über die Art und/oder den Zustand des Behälterinhalts, insbesondere auch über den Innendruck abgeben. In and / or on the film 9, at least one electronic, not shown, component, in particular a data memory, is attached, which can perform various tasks. Thus, this component can show whether the cap has been removed before. For this purpose, it is then ensured that a first-time acceptance of the cap 5 from the edge 3 changes a line or a component such that this is perceived by the electronic component or is pictured. Furthermore, the electronic component can provide information about the type and / or state of the container contents, in particular also about the internal pressure.
