Abstract

The container closure in the form of a plug has an outer wall which grips over the container edge and an originality securing ring which is attached to its underside by means of tear-off webs and has tabs on its inner cylindrical surface which are directed obliquely inwards and in the opening direction.

Description

Die Erfindung betrifft einen Behälterverschluß in Form eines Stopfens für einen Behälter mit einer am Rand von dessen zu verschließender Behälteröffnung vorgesehenen umlaufenden Umbördelung oder Randverstärkung mit einer den Behälterrand stirnseitig radial überragenden flachen Deckelpartie, an deren Rand eine zum Behälter gewandte äußere Wand angesetzt ist, an deren Unterseite mittels abreißbarer Stege ein Originalitätssicherungsring angesetzt ist, der an seiner inneren Zylinderfläche schräg nach innen und in Öffnungsrichtung gerichtete Laschen aufweist.The invention relates to a container closure in the form of a stopper for a container with a circumferential flanging or edge reinforcement provided at the edge of its container opening to be closed, with a flat lid portion projecting radially beyond the end of the container, on the edge of which an outer wall facing the container is attached, on the edge of which A tamper-evident securing ring is attached to the underside by means of webs that can be torn off, and has tabs on its inner cylindrical surface that are directed obliquely inwards and in the opening direction.

Behälterverschlüsse mit Originalitätssicherungsmitteln sind in vielfältigen Formen bekannt. Am häufigsten findet man sie in Form von Schraubverschlüssen, bei denen der Originalitätssicherungsring durch den unteren Rand des Gewindes zurückgehalten wird.Container closures with tamper-evident means are known in many forms. Most often they are found in the form of screw caps, in which the tamper-evident ring is retained by the lower edge of the thread.

Für Verschlußstopfen, die beispielsweise bei Röhrchen für Vitamin-Brausetabletten Anwendung finden, gibt es auch bereits Lösungsvorschläge. So kann der Sicherungsring beispielsweise dadurch an einer Randverdickung oder der Umbördelung des Röhrchens festgehalten werden, daß er an seiner Innenseite einen Wulst aufweist, der durch unterschiedliche Schrägflächen zwar das Aufstecken ermöglicht, aber beim Öffnen festgehalten wird. Infolge der Elastizität des Kunststoffs ist es jedoch nicht möglich, diesen Verschluß absolut sicher zu gestalten. Der Sicherungsring kann ohne Zuhilfenahme eines Werkzeugs beim Öffnen des Verschlusses über den Rand des Röhrchens geschoben werden, ohne daß er abreißt.There are already proposed solutions for sealing plugs, which are used, for example, in tubes for vitamin effervescent tablets. For example, the retaining ring can be held on a thickened edge or the flanging of the tube by having a bulge on the inside, which allows attachment by different inclined surfaces, but is held in place when opened. However, due to the elasticity of the plastic, it is not possible to make this closure absolutely secure. The locking ring can be pushed over the edge of the tube without the aid of a tool when the closure is opened, without tearing off.

Als sicherer gegen ein unbemerktes Öffnen des Verschlusses ohne Abreißen des Sicherungsrings ist demgegenüber eine Ausgestaltung des Verschlusses der eingangs erwähnten Art (FR-A-2 134 286) zu bewerten, bei welcher der Sicherungsring nicht mit einem umlaufenden, nach innen gerichteten Wulst, sondern mit einer Vielzahl von von seinen Innenflächen schräg nach innen und in Öffnungsrichtung gerichteten Laschen versehen ist, deren freie Enden krallenartig unter den Randwulst oder die Umbördelung des Behälterrandes greifen, so daß der Sicherungsring auch dann, wenn er sich elastisch aufzuweiten vermag, nicht über den Randwulst bzw. die Umbördelung hinwegtreten kann. Bei der Herstellung dieses bekannten Verschlusses im spritzgußverfahren aus Kunststoff stellt sich aber das Problem der Erzeugung der Zunge durch eine Ausbildung der Spritzgußform derart, daß die zwischen der Innenfläche des Sicherungsrings und den dieser zugewandten Rückseiten der Zungen entstehenden Hinterschnitträume einerseits durch entsprechende Vorsprünge der Spritzgußform erzeugt werden müssen, andererseits aber diese Vorsprünge die Entformung und das Auswerfen des Verschlusses nach der Erstarrung des eingespritzten Kunststoffes nicht behindern dürfen. Eine Lösung dieses spritztechnischen Problems erscheint bei dem bekannten Verschluß - wenn schon nicht ausgeschlossen - dann doch nur durch Verwendung sehr aufwendiger Spritzgußformen mit speziellen, die hinterschnittenen Räume im Bereich der Zunge erzeugenden Schiebern möglich, wobei diese Schieber in der die Innenfläche des Verschlusses erzeugenden Formenhälfte integriert sein müßten und vor der Entformung eine Drehung um ein von der Breite der Zungen abhängiges Winkelmaß ermöglichen müßten.In contrast, a design of the closure of the type mentioned at the beginning (FR-A-2 134 286), in which the securing ring is not provided with a circumferential, inwardly directed bead, but with, is to be rated as safer against an unnoticed opening of the closure without tearing off the securing ring a large number of tabs directed obliquely inward and in the opening direction is provided, the free ends of which engage like claws under the bead or the flange of the container edge, so that the retaining ring, even if it can expand elastically, does not extend over the bead or the flanging can step away. In the production of this known closure in the injection molding process from plastic, however, the problem of producing the tongue arises by designing the injection mold in such a way that the undercut spaces which arise between the inner surface of the securing ring and the rear sides of the tongues facing it are produced on the one hand by corresponding projections of the injection mold must, on the other hand, these projections the demolding and ejection of the closure after solidification of the injected plastic must not hinder. A solution to this injection molding problem appears in the known closure - if not excluded - only by using very complex injection molds with special sliders that create the undercut spaces in the area of the tongue, these sliders being integrated in the mold half producing the inner surface of the closure should be and should allow a rotation by an angular dimension dependent on the width of the tongues before removal from the mold.

Bei einer als Abdeckung für Aerosol-Sprühdosen vorgesehene Verschlußkappe ist zur Erzeugung von von einem Sicherungsring einwärts gerichteten Vorsprüngen eine Ausbildung der Spritzgußform bekannt (GB-A-1 423 834), bei welcher von der die Außenfläche der Form erzeugenden Formenhälfte Zungen vorspringen, welche die als Verriegelungskante wirkende Fläche der Vorsprünge erzeugen. Damit diese Zungen nicht zu lange und somit durch den Druck des schmelzflüssigen Kunststoffs beim Spritzgußvorgang bruchgefährdet sind, muß die bekannte Verschlußkappe eine unmittelbar oberhalb des Sicherungsrings liegende radiale Stufenfläche aufweisen, durch welche dann entsprechend kürzer zu bemessende Zungen hindurchgreifen. Beim Entformen der bekannten Verschlußkappe entstehen dann dem Querschnitt dieser Zungen entsprechende Ausschnitte in der Stufenfläche. Eine Übertragung dieser Technik auf den Verschlußstopfen gemäß der FR-A-2 134 286 ist aber nicht möglich, weil eine solche Stufenfläche nicht vorgesehen ist. An der äußeren Formenhälfte vorgesehene Zungen würden dann nämlich den Sicherungsring unterbrechen.In the case of a closure cap provided as a cover for aerosol spray cans, an injection mold design is known for producing projections directed inwards from a securing ring (GB-A-1 423 834), in which tongues project from the mold surface producing the outer surface, which tongues protrude generate the surface of the projections acting as a locking edge. So that these tongues are not too long and are therefore at risk of breakage due to the pressure of the molten plastic during the injection molding process, the known sealing cap must have a radial step surface located directly above the locking ring, through which then shorter tongues have to be dimensioned. When the known closure cap is removed from the mold, cutouts corresponding to the cross section of these tongues are formed in the step surface. A transfer of this technique to the sealing plug according to FR-A-2 134 286 is not possible, however, because such a step surface is not provided. Tongues provided on the outer mold half would then interrupt the locking ring.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, den gattungsmäßigen Behälterverschluß mit vertrebarem Aufwand im Spritzgußverfahren herzustellen und zugleich den Originalitätssicherungsring gegen ungewolltes Abreißen zu schützen.In contrast, the invention has for its object to produce the generic container closure with reasonable expenditure in the injection molding process and at the same time to protect the tamper-evident ring against unwanted tearing.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die äußere Wand die umlaufende Umbördelung oder Randversteifung des Behälterrands außen umgreift, daß der Außendurchmesser des Sicherungsrings den Außendurchmesser der umgreifenden Wand nicht überragt, und daß die ebenflächige Deckelpartie oberhalb der Laschen von einer der Anzahl und Breite der Laschen entsprechenden Anzahl von Ausschnitten durchsetzt wird. Dadurch, daß die ebenflächige Deckelpartie des Behälterverschlusses im Durchmesser so groß ausgebildet ist, daß die zum Behälter weisende Wand den Behälterrand zu umgreifen vermag, kann der Sicherungsring fluchtend unter der Wand angeordnet werden, und die von den Zungen in der äußeren Formenhälfte erzeugten Ausschnitte entstehen radial innerhalb der Wand unterhalb der flachen Deckelpartie. Da der Sicherungsring die zum Behälter zurückweisende Wand radial nicht überragt, ist auch eine erhöhte Sicherheit gegen ungewolltes Abreißen des Sicherungsrings gegeben.This object is achieved in that the outer wall surrounds the circumferential flanging or stiffening of the edge of the container on the outside, that the outer diameter of the retaining ring does not protrude beyond the outer diameter of the surrounding wall, and that the flat lid portion above the tabs of one of the number and width of the tabs appropriate number of cutouts is enforced. The fact that the flat lid part of the container closure is so large in diameter that the wall facing the container is able to encompass the edge of the container, the locking ring can be arranged in alignment under the wall, and the cutouts produced by the tongues in the outer mold half are created radially inside the wall below the flat lid section. Since the locking ring does not protrude radially beyond the wall facing the container, there is also increased security against unwanted tearing of the locking ring.

Ein Ausführungsbeispiel der Erfindung ist im folgenden anhand der beiliegenden Zeichnung beschrieben.An embodiment of the invention is described below with reference to the accompanying drawings.

Die Zeichnung zeigt einen Stopfen 1 zum Verschluß eines Röhrchens für Vitamin-Brausetabletten. Der Stopfen ist im oberen Teil der Zeichnung in Seitenansicht und teilweise geschnitten, im unteren Teil der Zeichnung in Aufsicht gezeigt. Auf der rechten, geschnittenen Seite ist zum besseren Verständnis das Röhrchen 2 eingezeichnet.The drawing shows a stopper 1 for closing a tube for vitamin effervescent tablets. The plug is shown in the upper part of the drawing in side view and partially cut, in the lower part of the drawing is shown in supervision. For a better understanding, tube 2 is drawn on the right, cut side.

Der Stopfen weist eine flache Deckelpartie 3 und eine äußere zylindrische Wand 4 auf, die über den Rand des Röhrchens greift. An der zylindrischen Außenfläche der Wand 4 sind umlaufende Rippen angebracht, um das Ergreifen beim Öffnen zu erleichtern.The stopper has a flat lid section 3 and an outer cylindrical wall 4 which engages over the edge of the tube. Circumferential ribs are attached to the cylindrical outer surface of the wall 4 in order to facilitate gripping when opening.

Der Stopfen ist in bekannter Weise mit einem federnd angebrachten Ring 5 zum Niederhalten des Inhalts des Röhrchens versehen. Außerdem weist der Stopfen eine Kammer 6 auf, die mit Trocknungsmittel 7 gefüllt ist. Die Kammer ist mit einem Deckel 8 abgeschlossen.The stopper is provided in a known manner with a spring-mounted ring 5 for holding down the contents of the tube. In addition, the stopper has a chamber 6 which is filled with drying agent 7. The chamber is closed with a lid 8.

Eine zylindrische Schürze 9 mit einem Außendurchmesser, der dem Innendurchmesser des Röhrchens 2 entspricht, dient dem luft- und feuchtigkeitsdichten Verschluß.A cylindrical apron 9 with an outer diameter, which corresponds to the inner diameter of the tube 2, is used for the air and moisture-tight closure.

Das Röhrchen 2 ist im vorliegenden Fall ein Metallröhrchen, das am oberen Rand eine Umbördelung 10 aufweist. Im Fall eines Kunstotoffröhrchens würde dies durch eine umlaufende Randverstärkung ersetzt werden.The tube 2 is a metal tube in the present case, which has a flange 10 at the upper edge. In the case of a plastic tube, this would be replaced by a peripheral edge reinforcement.

Die äußere Wand 4 der Deckelpartie 3 greift über diesen Rand und hält den Stopfen am Röhrchen fest.The outer wall 4 of the lid section 3 reaches over this edge and holds the stopper on the tube.

Mit der Unterseite der Wand 4 ist ein Originalitätssicherungsring 11 verbunden. Der Ring 11 ist zylindrisch, und die Verbindung mit der Wand 4 erfolgt durch dünne Stege 12, die bei geringem Kraftaufwand abreißen.A tamper-evident ring 11 is connected to the underside of the wall 4. The ring 11 is cylindrical, and the connection to the wall 4 is made by thin webs 12, which tear off with little effort.

Auf seiner Innenseite trägt der Ring 11 acht schräg nach innen und in Öffnungsrichtung gerichtete Laschen 13, die unter den umgebördelten Rand 10 des Röhrchens 2 greifen. Die Laschen 13 sind in gleichen Abständen um den Umfang verteilt und haben eine Breite, die etwa 20 Winkelgraden entspricht. Anstelle der beim vorliegenden Ausführungsbeispiel vorgesehenen acht Laschen können auch weniger oder mehr die gewünschte Funktion erfüllen. Die Laschen sind, wie der ganze Stopfen, aus Kunststoff und sind entsprechend elastisch. Beim Öffnen wirken die Laschen 13 wie Widerhaken und verkrallen sich unter der Ümbördelung 10 des Röhrchens, so daß der Ring 11 sicher zurückgehalten wird und die Stege 12 abreißen, wenn der Stopfen abgenommen wird.On its inside, the ring 11 carries eight tabs 13 directed obliquely inwards and in the opening direction, which engage under the flanged edge 10 of the tube 2. The tabs 13 are evenly spaced around the circumference and have a width which corresponds to approximately 20 degrees. Instead of the eight tabs provided in the present exemplary embodiment, fewer or more functions can also be performed. The tabs, like the entire stopper, are made of plastic and are accordingly elastic. When opened, the tabs 13 act like barbs and claw under the flanging 10 of the tube, so that the ring 11 is held back securely and the webs 12 tear off when the plug is removed.

Für die Herstellung der Laschen 13 ist es notwendig, den entsprechenden, hinter die Lasche greifenden Werkzeugteil von oben her einzusetzen, Aus diesem Grund weist der Deckel der Laschenzahl und -breite entsprechende Ausschnitte 14 auf.For the manufacture of the tabs 13, it is necessary to insert the corresponding tool part reaching behind the tab from above. For this reason, the cover has cutouts 14 corresponding to the number and width of the tabs.
