Abstract

A closure cap having a separate tamper indicating element made of plastic consists of a tamper indicating ring and a tear-off ring which is connected to said tamper indicating ring via tear-off webs, the tamper indicating element being engageable on the closure cap, and the tear-off ring engaging over a transfer ring of the bottle to be closed when the assembled closure cap is screwed on and resting with an annular shoulder against said transfer ring from the underside. To achieve defined tear-off characteristics of the webs and precise positioning of the tear-off ring relative to the transfer ring, provision is made for a plurality of centring knobs (23) to be arranged on the tear-off ring (18), distributed around its circumference, said centring knobs (23) projecting beyond the annular shoulder (24) of the tear-off ring (23), which annular shoulder faces the inside of the closure cap and rests against the transfer ring (7), and resting from the outside at least against the widest point of the transfer ring (7). <IMAGE>

Description

Die Erfindung richtet sich auf eine Verschlußkappe mit einem gesonderten Originalitäts-Sicherungselement aus Kunststoff bestehend aus einem Originalitätsring und einem über abreißbare Stege mit diesem verbundenen Abreißring, wobei das Originalitäts-Sicherungselement auf die Verschlußkappe aufrastbar ist, und wobei der Abreißring beim Aufschrauben der zusammengesetzten Verschlußkappe einen Transfer-Ring der zu verschließenden Flasche übergreift und von dessen Unterseite her mit einer Ringschulter an diesem anliegt.The invention relates to a closure cap with a separate tamper-evident element made of plastic, consisting of an tamper-evident ring and a tear-off ring connected to it by means of rip-off webs, the tamper-evident element being able to be snapped onto the closure cap, and the tear-off ring being one when the assembled closure cap is screwed on The transfer ring of the bottle to be closed overlaps and rests on the underside thereof with an annular shoulder.

Eine Verschlußkappe der gattungsgemäßen Art ist aus dem deutschen Patent 25 54 553 bekannt. Ein derartiger zweiteiliger Originalitätsverschluß weist den grundsätzlichen Vorteil auf, daß die einzelnen Teile herstellungstechnisch einfach realisierbar sind, daß das Originalitäts-Sicherungselement in einem Vormontageschritt einfach aufrastbar ist, und daß beim Abschrauben des Verschlusses das Sicherungselement vollständig abgetrennt wird, so daß sofort und dauernd das erstmalige Öffnen des Verschlusses erkennbar ist und bleibt, wobei das Aufschrauben mit vertretbar niedrigem Kraftaufwand erfolgen kann.A closure cap of the generic type is known from German Patent 25 54 553. Such a two-part tamper-evident closure has the basic advantage that the individual parts can be easily produced in terms of production technology, that the tamper-evident securing element can be simply snapped on in a pre-assembly step, and that when the closure is unscrewed, the securing element is completely separated off, so that the first time is permanent Opening of the closure is and remains recognizable, the screwing on being able to take place with a reasonably low expenditure of force.

Allerdings hat sich in der Praxis gezeigt, daß es zuweilen vorkommt, daß aufgrund kleiner spritztechnischer Unregelmäßigkeiten die Verbindungsstege zwischen Abreißring und Originalitätsring einseitig abreißen, so daß dann beim Weiterdrehen der Abreißring über die noch nicht abgetrennten Stege nach oben gezogen und teilweise über den Wulst gedrückt wird, so daß für die handhabende Person der Aufdrehvorgang mühsam wird, weil die beim Aufdrehvorgang übertragenen Kräfte kein gleichmäßiges Widerlager mehr finden.However, it has been shown in practice that it sometimes happens that, due to small spraying irregularities, the connecting webs between the tear-off ring and the tamper-evident ring tear off on one side, so that when the turn-off ring is turned further, it is pulled up over the not yet separated webs and is partially pressed over the bead , so that the unscrewing process becomes tedious for the handling person because the forces transmitted during the unscrewing process no longer find a uniform abutment.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Verschlußkappe der gattungsgemäßen Art so zu verbessern, daß beim Aufschrauben eine vorzeitige Beschädigung des Verschlusses vermieden wird und andererseits insbesondere beim Abschrauben ein gleichmäßiges Abreißen der Stege des Abreißrings bei niedrigen Abschraubkräften sichergestellt ist.Proceeding from this, the object of the invention is to improve a closure cap of the generic type in such a way that premature damage to the closure is avoided when it is screwed on and on the other hand, in particular when unscrewing, a uniform tearing off of the webs of the tear-off ring is ensured at low unscrewing forces.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an dem Abreißring eine Mehrzahl von um dessen Umfang verteilten Zentriernoppen angeordnet ist, wobei die Zentriernoppen die der Verschlußkappeninnenseite zugewandte, an dem Transfer-Ring anliegende Ringschulter des Abreißringes überragen und von außen wenigstens an der breitesten Stelle des Transfer-Ringes anliegen, wobei die Unterseite der Verschlußkappe zwischen dem Originalitätsring und diesen Zentriernoppen eingerastet ist.This object is achieved in that a plurality of centering knobs distributed around its circumference is arranged on the tear-off ring, the centering knobs projecting beyond the ring shoulder of the tear-off ring facing the inside of the closure cap and resting on the transfer ring and from the outside at least at the widest point of the transfer -Ringes abut, the underside of the cap is snapped between the tamper-evident ring and these centering knobs.

Die Zentriernoppen, die sich seitlich über den Transfer-Ring der Flasche erstrecken, sorgen für eine sehr definierte Positionierung des Abreißringes, so daß von dem Anfang des Abschraubvorgangs an die durch die Schraubbewegung übertragenen Abreißkräfte ein zuverlässiges und gleichmäßiges Widerlager finden. Darüber hinaus wirken die überstehenden Bereiche der Zentriernoppen als Hebelarme, welche ein Hochziehen des Abreißringes durch die auf die Stege wirkenden Abreißkräfte unterbinden und dadurch das Abreißen der Stege erleichtern.The centering knobs, which extend laterally over the transfer ring of the bottle, ensure a very defined positioning of the tear-off ring, so that from the beginning of the unscrewing process, the tear-off forces transmitted by the screwing movement find a reliable and uniform abutment. In addition, the protruding areas of the centering knobs act as lever arms, which prevent the tear-off ring from being pulled up by the tear-off forces acting on the webs and thereby make it easier to tear off the webs.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß die Unterkante der Verschlußkappe gegenüber der Oberkante des Originalitäts-Sicherungselementes eine Montageschräge aufweist. Hierdurch wird sichergestellt, daß die Verschlußkappe problernlos mit dem Originalitäts-Sicherungselement verrastbar ist, auch wenn sich beim Entformungsvorgang Abweichungen von der Sollkonfiguration ergeben bzw. wenn Grate verbleiben. Die Montageschräge der Verschlußkappe wirkt zusammen mit einer entsprechenden inneren Schrägfläche bzw. einem inneren konischen Abschnitt an der Oberseite des Originalitätssicherungsringes.In a further embodiment of the invention, it can be provided that the lower edge of the closure cap has a mounting slope relative to the upper edge of the tamper-evident element. This ensures that the closure cap can be easily locked with the tamper-evident element, even if there are deviations from the desired configuration during the demolding process or if burrs remain. The mounting bevel of the closure cap works together with a corresponding inner inclined surface or an inner conical section on the top of the tamper-evident ring.

Vorteilhafterweise ist weiterhin vorgesehen, daß die Verschlußkappe oberhalb des innenliegenden Rastwulstes des Originalitätssicherungsringes einen Anschlagwulst aufweist. Hierdurch wird das Originalitäts-Sicherungselement gegenüber der Verschlußkappe in axialer Richtung definiert und sicher festgelegt, so daß ein problemloses Auf- und Abschrauben gewährleistet ist.It is also advantageously provided that the closure cap has a stop bead above the inner locking bead of the tamper-evident ring. As a result, the tamper-evident element is defined in relation to the closure cap in the axial direction and securely fixed, so that problem-free screwing and unscrewing is ensured.

Mit Vorteil kann weiterhin vorgesehen sein, daß die Verschlußkappe einen unteren Zylinderabschnitt aufweist, der die Zentriernoppen des Abreißringes um- und übergreift, wobei an der Innenseite dieses Zylinderabschnittes im Übergangsbereich zur Verschlußkappe eine Hinterschneidung vorgesehen ist. Durch diese Hinterschneidung wird einerseits die Montage des Originalitäts-Sicherungselementes an der Verschlußkappe begünstigt und andererseits der Aufschraubvorgang durch die Zentriernoppen nicht behindert, sondern in der vorstehend beschriebenen Weise unterstützt.It can also be advantageously provided that the closure cap has a lower cylinder section which engages around and overlaps the centering knobs of the tear-off ring, an undercut being provided on the inside of this cylinder section in the transition region to the closure cap. This undercut on the one hand favors the assembly of the tamper-evident element on the closure cap and on the other hand the screwing-on process is not impeded by the centering knobs but is supported in the manner described above.

In der Zeichnung ist eine Verschlußkappe 1 dargestellt, welche an ihrer Außenseite in an sich bekannter Weise mit einer Mehrzahl von in axialer Richtung verlaufenden Greifrippen 2 versehen ist. An der Innenseite der Verschlußkappe 1 ist ein Innengewinde 3 angeordnet, welches das Aufschrauben auf eine in Fig. 1 gestrichelt angedeutete Flasche 4 bzw. auf ein Außengewinde 5 am Hals 6 der Flasche 4 ermöglicht. Unterhalb des Außengewindes 5 ist am Hals 6 der Flasche 4 ein nach außen wulstartig vorspringender Transfer-Ring 7 ausgebildet, der nach oben hin eine flach nach innen verlaufende Schrägfläche 8 und an seiner Unterseite eine nahezu rechtwinklig nach innen verlaufende Schrägfläche 9 aufweist.In the drawing, a closure cap 1 is shown, which is provided on its outside in a manner known per se with a plurality of gripping ribs 2 running in the axial direction. An internal thread 3 is arranged on the inside of the closure cap 1, which thread enables screwing onto a bottle 4 indicated by dashed lines in FIG. 1 or onto an external thread 5 on the neck 6 of the bottle 4. Below the external thread 5 on the neck 6 of the bottle 4 there is a transfer ring 7 which projects outwards in a bead-like manner and which has a flat inwardly sloping surface 8 and an underside which is almost at right angles inwards on its underside.

Die Verschlußkappe 1 weist im Bereich ihres unteren Randes einen Zylinderabschnitt 10 auf, der zur Unterkante 11 hin in eine Montageschrägfläche 12 übergeht. In diesem Bereich sind auch Ausnehmungen 13 angeordnet, welche für eine Verdrehsicherung in der Form sorgen. An der Innenseite des Zylinderabschnittes 10 ist eine Hinterschneidung 11 vorgesehen, welche überraschenderweise ein besonders günstiges Verhalten beim Auf- und Abschrauben ermöglicht.The closure cap 1 has in the region of its lower edge a cylinder section 10 which merges into a mounting bevel surface 12 towards the lower edge 11. In this area there are also recesses 13 which ensure that the mold is secured against rotation. An undercut 11 is provided on the inside of the cylinder section 10, which surprisingly enables a particularly favorable behavior when screwing on and off.

Oberhalb des Zylinderabschnittes 10 ist im Abstand zu diesem unter Ausbildung einer Rastnut 14 ein Anschlagwulst 15 vorgesehen.Above the cylinder section 10, a stop bead 15 is provided at a distance from it, forming a locking groove 14.

Das in Fig. 3 dargestellte Originalitäts-Sicherungselement 16 umfaßt einen Originalitätssicherungsring 17 und einen Abreißring 18, der mit dem Originalitätssicherungsring 17 über eine Mehrzahl dünner Stege 19 verbunden ist. Der Abreißring 18 erstreckt sich konisch nach innen oben und weist an seiner Innenseite über den Umfang verteilt eine Mehrzahl von V-förmigen Abschnitten 20 mit reduzierter Wandstärke auf, welche das Überstreifen des Abreißringes 18 über den Transfer-Ring 7 einer Flasche 4 erleichtern.The tamper-evident element 16 shown in FIG. 3 comprises an tamper-evident ring 17 and a tear-off ring 18 which is connected to the tamper-evident ring 17 via a plurality of thin webs 19. The tear-off ring 18 extends conically inwards and has on its inside distributed over the circumference a plurality of V-shaped sections 20 with reduced wall thickness, which make it easier to slip on the tear-off ring 18 via the transfer ring 7 of a bottle 4.

Der Originalitätssicherungsring 17 weist im Bereich seiner Oberkante an der Innenseite einen Rastwulst 21 auf, wobei an der Oberseite des Rastwulstes 21 eine Schrägfläche 22 ausgebildet ist, die beim Verrasten der Verschlußkappe 1 mit dem Originalitäts-Sicherungselement 16 mit der Schrägfläche 12 an dem Zylinderabschnitt 10 der Verschlußkappe 1 zusammenwirkt. Bei diesem Einrastvorgang gelangt der Rastwulst 21 des Originalitätssicherungsringes 17 in die Rastnut 14 zwischen dem Anschlagwulst 15 und dem nach außen vorspringenden Zylinderabschnitt 10 der Verschlußkappe 1 und ist damit axial definiert festgelegt.The tamper-evident ring 17 has in the region of its upper edge on the inside a latching bead 21, an inclined surface 22 being formed on the top of the latching bead 21 which, when the closure cap 1 is latched with the tamper-evident locking element 16 with the oblique surface 12 on the cylinder section 10 Cap 1 interacts. During this latching process, the latching bead 21 of the tamper-evident locking ring 17 enters the latching groove 14 between the stop bead 15 and the outwardly projecting cylinder section 10 of the closure cap 1 and is thus axially defined.

An dem Abreißring 18 ist über den Umfang verteilt eine Mehrzahl von Zentriernoppen 23 angeordnet, welche die obere Ringschulter 24 des Abreißringes 18, welche in dem in Fig. 1 dargestellten montierten Zustand an der Schrägfläche 9 des Transfer-Rings 7 der Flasche 4 anliegt, nach oben hin mit einem Abschnitt 25 derart überragen, daß dieser Abschnitt 25 an der breitesten Steile des Transfer-Rings 7 außen an diesem anliegt und einen Hebelarm ausbildet, der verhindert, daß der Abreißring 18 beim Aufschrauben aufgrund der durch die Stege 19 übertragenen Abreißkräfte angehoben und über den Transfer-Ring 7 hochgezogen wird.On the tear-off ring 18, a plurality of centering knobs 23 are arranged distributed over the circumference, which follow the upper ring shoulder 24 of the tear-off ring 18, which in the assembled state shown in FIG. 1 bears against the inclined surface 9 of the transfer ring 7 of the bottle 4 protrude above with a section 25 such that this section 25 abuts the widest part of the transfer ring 7 on the outside thereof and forms a lever arm which prevents the tear-off ring 18 from being lifted when screwing on due to the tear-off forces transmitted by the webs 19 and is pulled up over the transfer ring 7.
