Description

Die Erfindung betrifft Sicherungsringe für Flaschen-, Weithals- oder ähnliche Behälterverschlusse entsprechend dem Oberbegriff des Anspruchs 1, bestehend aus einem von außen auf den Behälterverschluß aufzusetzenden Befestigungsteil und mehreren daran befestigten Sicherungsklauen. Die Sicherungsklauen greifen nach dem Aufsetzen des Verschlusses auf einen Behälter unter einen an dessen Außenseite angebrachten Ringwulst. Beim ersten Öffnen bzw. Aufdrehen des Verschlusses bleiben die Sicherungsklauen an dem Ringwulst hängen und werden dadurch von dem Befestigungsteil des Sicherungsrings mehr oder weniger abgetrennt.The invention relates to locking rings for bottle, wide neck or similar container closures according to the preamble of claim 1, consisting of a fastening part to be placed on the outside of the container closure and a plurality of securing claws attached thereto. After the closure has been put in place, the securing claws grip a container under an annular bead attached to the outside thereof. When the lock is opened or unscrewed for the first time, the locking claws get caught on the ring bead and are thereby more or less separated from the fastening part of the locking ring.

Ein Sicherungsring entsprechend dem Oberbegriff des Patentanspruchs 1 ist aus der DE-OS 25 54 553 bekannt. Hierbei sind die Sicherungsklauen durch einzelne, zwischen ihnen vorgesehene axiale Dehnungsschlitze in Umfangsrichtung voneinander getrennt. Die einzelnen Sicherungsklauen sind über radiale Stege mit dem Befestigungsteil des Sicherungsrings verbunden. Am Übergang zwischen den Stegen und dem Befestigungsteil sind Sollbruchstellen mit verminderter Wandstärke vorgesehen.A locking ring according to the preamble of claim 1 is known from DE-OS 25 54 553. Here, the securing claws are separated from one another in the circumferential direction by individual axial expansion slots provided between them. The individual locking claws are connected to the fastening part of the locking ring via radial webs. At the transition between the webs and the fastening part, predetermined breaking points with reduced wall thickness are provided.

Beim Abdrehen dieses bekannten Verschlusses von dem Behälter reißen die Sicherungsklauen von dem Befestigungsteil des Sicherungsrings ab und bleiben unterhalb des Behälterwulstes als geschlossener Ring hängen, weil die axialen Dehnungsschlitze nicht vollständig bis zur unteren Kante der Sicherungsklauen durchgehen, so daß in diesem Bereich eine durchgehende ringförmige Verbindung der Sicherungsklauen vorliegt.When this known closure is unscrewed from the container, the locking claws tear off the fastening part of the locking ring and remain underneath the container bead as a closed ring, because the axial expansion slots do not go all the way to the lower edge of the locking claws, so that a continuous annular connection in this area the safety claws are present.

Da die vom Befestigungsteil abgerissenen Sicherungsklauen als Ring an dem Behälter hängenbleiben und bei dessen Wiederverwendung umständlich entfernt werden müssen, ist ein solcher Verschluß insbesondere für Pfandbehälter ungeeignet.Since the securing claws torn off the fastening part remain attached to the container as a ring and have to be laboriously removed when they are reused, such a closure is particularly unsuitable for deposit containers.

Aufgabe der Erfindung ist es daher, die genannten Nachteile zu vermeiden und einen Sicherungsring für Behälterverschlüsse zu schaffen, der einfach herstellbar und sicher mit dem Behälterverschluß verbunden ist und der umweltfreundlich recycliert werden kann.The object of the invention is therefore to avoid the disadvantages mentioned and to provide a locking ring for container closures which is simple to manufacture and securely connected to the container closure and which can be recycled in an environmentally friendly manner.

Diese Aufgabe wird durch die in den Patentansprüchen, insbesondere im Patentanspruch 1, angegebenen Merkmale gelöst.This object is achieved by the features specified in the claims, in particular in claim 1.

Hiernach ist zusätzlich zu den Sollbruchstellen an den Stegen zwischen den Sicherungsklauen und dem Befestigungsteil mindestens ein Anbindungssteg vorgesehen, der einen größeren Querschnitt als die Sollbruchstellen hat. Beim erstmaligen Öffnen des Verschlusses verhaken sich somit die Sicherungsklauen unter dem Ringwulst des Behälters und reißen leicht an den Sollbruchstellen ab. Infolge des zusätzlichen Anbindungsstegs werden jedoch die abgerissenen Sicherungsklauen in zusammenhängender Ringform am Sicherungsring und damit an dem abgezogenen Behälterverschluß festgehalten. Sie stehen wie Fahnen von dem Behälterverschluß ab und lassen sich mechanisch zusammen mit dem Befestigungsteil des Sicherungsrings gut von dem Material des eigentlichen Behälterverschlusses trennen, um so eine Recyclierung zu ermöglichen. Auch in optischer Hinsicht wird durch die herausstehenden Fahnen der eigentliche Zweck des Sicherungsrings in hervorragender Weise erfüllt, es wird nämlich nach außen hin kenntlich gemacht, daß der Behälter bereits einmal geöffnet wurde.According to this, in addition to the predetermined breaking points on the webs between the securing claws and the fastening part, at least one connecting web is provided, which has a larger cross section than the predetermined breaking points. When the closure is opened for the first time, the securing claws get caught under the ring bulge of the container and tear off easily at the predetermined breaking points. As a result of the additional connecting web, however, the torn-off securing claws are held in a coherent ring shape on the securing ring and thus on the removed container closure. They protrude from the container closure like flags and can be mechanically separated from the material of the actual container closure together with the fastening part of the securing ring, in order to enable recycling. From an optical point of view, the actual purpose of the circlip is excellently fulfilled by the protruding flags, namely that it is indicated to the outside that the container has already been opened.

Die Unteransprüche kennzeichnen vorteilhafte Weiterbildungen der Erfindung. Gemäß Anspruch 2 sind mehrere, insbesondere zwei Anbindungsstege über den Umfang des Sicherungsrings verteilt angeordnet. Somit bilden sich beim erstmaligen Öffnen des Verschlusses zwei abstehende Fahnen, die sich jeweils über etwa 180° in Umfangsrichtung erstrecken.The subclaims characterize advantageous developments of the invention. According to claim 2, several, in particular two connecting webs are arranged distributed over the circumference of the securing ring. Thus, when the closure is opened for the first time, two protruding flags are formed, each of which extends over approximately 180 ° in the circumferential direction.

Gemäß Anspruch 3 sind die Anbindungsstege und die Sollbruchstellen jeweils in den Räumen zwischen den Sicherungsklauen angeordnet, so daß der Sicherungsring leicht herstellbar ist und die Sollbruchstellen beim erstmaligen Aufdrehen des Verschlusses sicher aufreißen.According to claim 3, the connecting webs and the predetermined breaking points are each arranged in the spaces between the securing claws, so that the securing ring can be produced easily and the predetermined breaking points are torn open when the closure is unscrewed for the first time.

Nach Anspruch 4 weist der Befestigungsteil des Sicherungsrings am oberen Rand eine wulstförmige Verdickung auf, mit deren Hilfe er fest am unteren Rand des Behälterverschlusses verankert werden kann. Wenn zusätzlich gemäß Anspruch 5 der Befestigungsteil des Sicherungsrings an der oberen Abschlußkante eine sägezahnförmige Aufrauhung aufweist, wird der Sicherungsring hakenartig oder formschlüssig mit dem unteren Rand des Behälterverschlusses verklammert.According to claim 4, the fastening part of the securing ring has a bead-shaped thickening at the upper edge, with the aid of which it can be firmly anchored to the lower edge of the container closure. If, in addition, according to claim 5, the fastening part of the securing ring has a sawtooth-shaped roughening at the upper end edge, the securing ring is clamped like a hook or in a form-fitting manner with the lower edge of the container closure.

Schließlich kann gemäß Anspruch 6 die Anzahl der Sicherungsklauen vorzugsweise sechs oder acht betragen, die symmetrisch über den Umfang verteilt und von einer gleichen Zahl von Sollbruchstellen gehalten sind. Infolge dieser Ausbildung ergibt sich eine leicht herstellbare und trotzdem besonders wirkungsvolle Ausbildung des Sicherungsrings.Finally, the number of securing claws can preferably be six or eight, which are distributed symmetrically over the circumference and are held by an equal number of predetermined breaking points. As a result of this training, the locking ring is easy to manufacture and yet particularly effective.

Im folgenden wird die Erfindung anhand von Ausführungsbeispielen in Verbindung mit der Zeichnung näher erläutert. Es zeigen:

The invention is explained in more detail below on the basis of exemplary embodiments in conjunction with the drawing. Show it:

a container closure, partially in longitudinal section, with the locking ring according to the invention;
Fig. 2
a cross section through the locking ring with a connecting web;

Gemäß Fig. 1 ist der Sicherungsring 1 mittels eines Befestigungsteils 2 auf einen Behälterverschluß 3 aufgeschoben, der an seinem unteren Rand eine wulstförmige Verdickung 4 aufweist. Der Befestigungsteil 2 des Sicherungsrings 1 weist an seinem oberen Rand eine entsprechende wulstförmige Verdickung 17 auf. Die in Umfangsrichtung wirkenden Druckspannungen zwischen den beiden Wülsten 4 und 17 sind so bemessen, daß sich der Behälterverschluß 3 mit dem Sicherungsring 1 und mit den daran an einem Ringteil 5 angeordneten, sehr beweglichen Sicherungsklauen 5a - 5h leicht von oben über die entsprechende Behälteröffnung schieben läßt. Die am unteren Rand des Sicherungsrings 1 bzw. an dessen Befestigungsteil 2 angeordneten Sicherungsklauen 5a - 5h sind über Stege 6 mit dem Befestigungsteil 2 verbunden. Dabei ist die Beweglichkeit der Sicherungsklauen 5a - 5h so eingestellt, daß einerseits das Aufschieben auf die Mündung des Behälterhalses beim Verschließen und andererseits das Abreißen der Sicherungsklauen beim erstmaligen Öffnen des Behälterverschlusses garantiert ist.1, the securing ring 1 is pushed onto a container closure 3 by means of a fastening part 2, which has a bead-shaped thickening 4 on its lower edge. The fastening part 2 of the locking ring 1 has a corresponding bead-shaped thickening 17 on its upper edge. The compressive stresses acting in the circumferential direction between the two beads 4 and 17 are dimensioned such that the container closure 3 with the securing ring 1 and with the very movable securing claws 5a-5h arranged thereon on a ring part 5 can easily be pushed over the corresponding container opening from above . The securing claws 5a - 5h arranged on the lower edge of the securing ring 1 or on its fastening part 2 are connected to the fastening part 2 via webs 6. The mobility of the locking claws 5a - 5h is set so that, on the one hand, it is guaranteed that it is pushed onto the mouth of the container neck when it is closed and, on the other hand, that the locking claws will be torn off when the container closure is opened for the first time.

Hierzu sind die Stege 6, wie die Fig. 2 und 4 zeigen, über den Umfang verteilt einerseits als Anbindungsstege 7 und 8 und andererseits als Sollbruchstellen 9 bis 16 ausgebildet. Gemäß Fig. 2 ist nur ein einziger Anbindungssteg 7 vorhanden, während gemäß Fig. 4 zwei Anbindungsstege 7 und 8 etwa diametral einander gegenüber vorgesehen sind. Man erkennt, daß die Sollbruchstellen 9 bis 16 wesentlich dünnere Wandstärken aufweisen als die Anbindungsstege 7 und 8, die beim Abdrehen des Verschlusses eine dauerhafte Befestigung der Sicherungsklauen 5a - 5h an dem Sicherungsring 1 ermöglichen. Die Sicherungsklauen 5a - 5h treten in diesem Fall als Fahne aus dem Sicherungsring 1 heraus und zeigen so nach außen deutlich sichtbar an, daß der Behälter geöffnet wurde.For this purpose, the webs 6, as shown in FIGS. 2 and 4, are designed distributed over the circumference on the one hand as connecting webs 7 and 8 and on the other hand as predetermined breaking points 9 to 16. According to FIG. 2, only a single connecting web 7 is present, while according to FIG. 4 two connecting webs 7 and 8 are provided approximately diametrically opposite one another. It can be seen that the predetermined breaking points 9 to 16 have much thinner wall thicknesses than the connecting webs 7 and 8, which, when the closure is unscrewed, enable the securing claws 5a - 5h to be permanently attached to the securing ring 1. In this case, the securing claws 5a - 5h emerge as a flag from the securing ring 1 and thus clearly indicate to the outside that the container has been opened.

Während bei dem Ausführungsbeispiel nach Fig. 2 beim Öffnen nur eine Ringfahne gebildet wird, handelt es sich beim Ausführungsbeispiel nach Fig. 4 um zwei durch zwei Ringteile 5 gebildete Fahnen, da hier zwei Anbingdungsstege 7 und 8 vorhanden sind. Für die Recyclierung ist es von entscheidender Bedeutung, daß der Kunststoff des Sicherungsrings möglichst in einem Teil leicht von dem übrigen Verschluß getrennt werden kann und nicht etwa Bruchstücke in die Behältermündung hineingelangen.While only one ring flag is formed in the embodiment according to FIG. 2 when opened, the embodiment according to FIG. 4 is two flags formed by two ring parts 5, since two attachment webs 7 and 8 are present here. For recycling, it is of crucial importance that the plastic of the retaining ring can be easily separated from the rest of the closure, if possible, and that fragments do not get into the mouth of the container.

Fig. 3 zeigt eine weitere Variante des Sicherungsrings 1 mit geändertem Befestigungsteil 2, der an seinem oberen Rand mittels einer sägezahnförmigen Aufrauhung 18 am unteren Rand des Behälterverschlusses 3 eingreift. Außerdem hat hierbei der Sicherungsring 1 axial verkürzte Sicherungsklauen 5a - 5d. Hierdurch wird die Aufsteckbarkeit des Sicherungsrings 1 auf die Behältermündungen weiter verbessert, und die Verbindungstechnik zwischen Behälterverschluß 3 und Sicherungsring I wird vereinfacht. Verschluß und Sicherungsring werden einfach ineinandergesteckt und können vor der Recyclierung leicht durch tangentialen Druck voneinander getrennt werden. Die Haftung zwischen dem Sicherungsring 1 und dem Behälterverschluß 3 muß lediglich etwas größer bemessen sein als der beim Aufdrehen des Behälterverschlusses infolge des Zugs der Sicherungsklauen 5a - 5d auftretende Abreißdruck.Fig. 3 shows a further variant of the locking ring 1 with a modified fastening part 2, which engages at its upper edge by means of a sawtooth-shaped roughening 18 at the lower edge of the container closure 3. In addition, the locking ring 1 has axially shortened locking claws 5a - 5d. This further improves the ability of the locking ring 1 to be plugged onto the container mouths, and the connection technology between the container closure 3 and the locking ring I is simplified. Closure and locking ring are simply plugged into each other and can be easily separated by tangential pressure before recycling. The liability between the locking ring 1 and the container closure 3 only has to be dimensioned somewhat larger than the tear-off pressure which occurs when the container closure is unscrewed due to the pulling of the locking claws 5a-5d.
