Abstract

A screw cap, especially one made of plastic, for closing a bottle or the like, with a cylindrical threaded section having a female thread to be screwed on the male thread of a bottle-neck, connected to the security ring via break points, on which there are inwardly-directed catches to engage with an outer collar on a bottle-neck. The free edge (14) of the cylindrical part (3) has at least one axial projection (15) which engages positively in a recess (17) in the opposite edge of the security ring (11) in the circumferential direction and releasably in the axial direction. This positive toothing ensures that, when the screw cap is first screwed on the neck of a bottle, the webs (10) are not sheared off by increased torques which can be applied if the catches run on the outer collar of the bottle-neck under tension.

Description

Schraubkappe, insbesondere aus Kunststoff, zum Verschließen einer Flasche oder dergleichen Screw cap, in particular made of plastic, for closing a bottle or the like
Die Erfindung betrifft eine Schraubkappe der im Ober¬ begriff des Anspruchs 1 genannten Art zum Verschließen einer Flasche oder dergleichen.The invention relates to a screw cap of the type mentioned in the preamble of claim 1 for closing a bottle or the like.
Durch DE 41 08 453 AI ist eine Schraubkappe der be- treffenden Art bekannt, bei der die nach innen gerichteten Rastvorsprünge hakenförmig ausgebildet sind, so daß beim erstmaligen Aufschrauben der Schraubkappe auf das Außen¬ gewinde eines Flaschenhalses die Rastvorsprünge hinter einen zu Sicherungszwecken am Flaschenhals angeordneten, umlaufenden Außenwulst schnappen. Beim Abschrauben der Schraubkappe halten die hakenförmigen Rastvorsprünge den Sicherungsring hinter dem Außenwulst am Flaschenhals fest, so daß die durch dünne Stege zwischen dem Sicherungsring und dem zylindrischen Teil der Schraubkappe gebildeten Sollbruchstellen abreißen und so der Sicherungsring auf dem Flaschenhals verbleibt. Dadurch ist eine Originali¬ tätssicherung gegeben, indem nach Wiederaufschrauben der Schraubkappe der Sicherungsring lose auf dem Flaschenhals gehalten ist. Dadurch ist für jeden leicht erkennbar, daß die Flasche bereits einmal geöffnet worden ist.From DE 41 08 453 AI a screw cap of the type in question is known, in which the inward locking projections are hook-shaped, so that when the screw cap is first screwed onto the external thread of a bottle neck, the locking projections are arranged behind one for security purposes on the bottle neck , snap the outer bead. When unscrewing the screw cap, the hook-shaped locking projections hold the retaining ring behind the outer bead on the bottle neck, so that the predetermined breaking points formed by thin webs between the retaining ring and the cylindrical part of the screw cap tear off and the retaining ring thus remains on the bottle neck. This ensures originality by holding the locking ring loosely on the bottle neck after screwing the screw cap back on. This makes it easy for everyone to see that the bottle has already been opened.
Ein Nachteil dieser bekannten Schraubkappe besteht darin, daß ein verhältnismäßig großes Drehmoment erforder¬ lich ist, wenn die hakenförmigen Rastvorsprünge an dem Sicherungsring über den Außenwulst am Flaschenhals hinweg¬ bewegt werden. Aufgrund dieses erhöhten Drehmoments be¬ steht die Gefahr, daß die durch die dünnen Stege gebilde¬ ten Sollbruchstellen zwischen dem Sicherungsring und dem zylindrischen Teil der Schraubkappe bereits beim Auf¬ schrauben abgeschert werden, so daß nachfolgend der Siche¬ rungsring lose auf dem Hals der Flasche sitzt, genauso, wie das der Fall ist, wenn die Flasche erstmalig geöffnet und dann wieder verschlossen worden ist. Die Originalität des Flascheninhalts ist daher nicht erkennbar oder gewähr¬ leistet .A disadvantage of this known screw cap is that a relatively large torque is required if the hook-shaped locking projections on the Circlip can be moved over the outer bead on the bottle neck. Because of this increased torque, there is the danger that the predetermined breaking points formed by the thin webs between the locking ring and the cylindrical part of the screw cap will be sheared off when screwing on, so that subsequently the locking ring will loosely rest on the neck of the bottle sits, just as it does when the bottle is first opened and then closed again. The originality of the bottle contents is therefore not recognizable or guaranteed.
Der Erfindung liegt die Aufgabe zugrunde, eine Schraubkappe der betreffenden Art zu schaffen, bei der die Gefahr des Abreißens der Sollbruchstellen zwischen dem zylindrischen Teil der Schraubkappe und dem Sicherungsring beim erstmaligen Aufschrauben verringert ist.The invention has for its object to provide a screw cap of the type in question, in which the risk of tearing off the predetermined breaking points between the cylindrical part of the screw cap and the locking ring is reduced when screwing on for the first time.
Die der Erfindung zugrundeliegende Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebene Lehre ge¬ löst. Der Grundgedanke dieser Lehre besteht darin, den zy¬ lindrischen Teil der Schraubkappe und den Sicherungsring in Umfangsrichtung formschlüssig, in Schraubrichtung je¬ doch lösbar miteinander zu verbinden. Durch formschlüssi¬ ges Ineinandergreifen der gegenüberliegenden Ränder von zylindrischem Teil und Sicherungsring können große Drehmo¬ mente ohne gegenseitige Drehbewegung der beiden Teile übertragen werden, so daß keine Gefahr besteht, daß die den Sicherungsring im Originalzustand mit dem zylindri¬ schen Teil der Schraubkappe verbindenden Sollbruchstellen abgeschert oder abgerissen werden.The object on which the invention is based is achieved by the teaching specified in the characterizing part of claim 1. The basic idea of this teaching is to positively connect the cylindrical part of the screw cap and the locking ring in the circumferential direction, but releasably in the screwing direction. By interlocking the opposing edges of the cylindrical part and the locking ring, large torques can be transmitted without mutual rotation of the two parts, so that there is no danger that the predetermined breaking points connecting the locking ring in the original state with the cylindrical part of the screw cap will shear off or be demolished.
Der Vorsprung und die Ausnehmung sind zweckmäßigerwei¬ se rechteckig, wobei mehrere Vorsprünge und Ausnehmungen vorteilhafterweise vorgesehen sind, die vorzugsweise mäan- derförmig ineinandergreifen. Die Stege können sich grund- sätzlich an beliebigen Stellen befinden, also z.B. dort, wo keine Vorsprünge und Ausnehmungen ineinandergreifen. Zweckmäßigerweise befinden sich die Sollbruchstellen zwi¬ schen in Umfangsrichtung aneinander angrenzenden Flächen der Vorsprünge und Ausnehmungen. Die Sollbruchstellen kön¬ nen auch durch zwischen den Vorspüngen und Ausnehmungen angeordnete Stege gebildet sein. Die Verzahnung erstreckt sich zweckmäßigerweise über den gesamten Umfang.The projection and the recess are expediently rectangular, a plurality of projections and recesses being advantageously provided, which preferably engage in a meandering manner. In principle, the webs can be located anywhere, for example there, where there are no projections and recesses. The predetermined breaking points are expediently located between surfaces of the projections and recesses which adjoin one another in the circumferential direction. The predetermined breaking points can also be formed by webs arranged between the projections and recesses. The toothing expediently extends over the entire circumference.
Anhand der Zeichnung soll die Erfindung näher erläu¬ tert werden.The invention will be explained in more detail with reference to the drawing.
Fig. 1 zeigt einen Axialschnitt durch ein Ausfüh¬ rungsbeispiel einer Schraubkappe gemäß der Erfindung, zusammen mit einem zugehörigen Hals einer Flasche, Fig. 2 ist eine vergrößerte Ansicht II in Fig. 1,1 shows an axial section through an exemplary embodiment of a screw cap according to the invention, together with an associated neck of a bottle, FIG. 2 is an enlarged view II in FIG. 1,
Fig. 1 zeigt eine Schraubkappe 1 aus Kunststoff gemäß einem Ausführungsbeispiel der Erfindung. Sie weist einen Boden 2 und ein zylindrisches Schraubteil 3 auf mit einem Innengewinde 4 zum Aufschrauben auf ein Außengewinde 5 eines Flaschenhalses 6, der nur teilweise dargestellt ist. Zwischen dem Boden 2 und einer Stirnkante 7 des Flaschen¬ halses 6 befindet sich eine Dichtung 8.Fig. 1 shows a screw cap 1 made of plastic according to an embodiment of the invention. It has a base 2 and a cylindrical screw part 3 with an internal thread 4 for screwing onto an external thread 5 of a bottle neck 6, which is only partially shown. A seal 8 is located between the base 2 and an end edge 7 of the bottle neck 6.
Ein unterer Rand 9 des zylindrischen Teils 3 ist über Stege 10 mit einem Sicherungsring 11 verbunden, der innen Rastvorsprünge 12 aufweist, die in dem dargestellten Auf¬ schraubzustand einen Außenwulst 13 am Flaschenhals 6 hin¬ tergreifen.A lower edge 9 of the cylindrical part 3 is connected via webs 10 to a locking ring 11 which has locking projections 12 on the inside which, in the screwed-on state shown, engage an outer bead 13 on the bottle neck 6.
Fig. 2 zeigt eine Ansicht II in Fig. 1. Aus ihr ist zu erkennen, daß ein unterer Rand 14 des zylindrischen Teils 3 rechteckige Vorsprünge 15 aufweist, die bündig in ent¬ sprechende Ausnehmungen 16 in dem Sicherungsring 11 ein¬ greifen. Zwischen den Vorsprüngen 15 und dem Boden der Ausnehmungen 11 ist ein Zwischenraum 17 gebildet, in dem die Stege 10 angeordnet sind, die den Sicherungsring 11 an dem zylindrischen Teil halten.FIG. 2 shows a view II in FIG. 1. From this it can be seen that a lower edge 14 of the cylindrical part 3 has rectangular projections 15 which engage flush in corresponding recesses 16 in the locking ring 11. Between the projections 15 and the bottom of the recesses 11, an intermediate space 17 is formed, in which the webs 10 are arranged, which attach the locking ring 11 hold the cylindrical part.
Beim erstmaligen Aufschrauben einer Schraubkappe 1 gemäß Fig. 1 sorgen die aus Fig. 2 ersichtlichen Vorsprün¬ ge 15 dafür, daß der Sicherungsring 11 auch dann ohne ge- genseitige Bewegung mitgenommen wird, wenn ein größeres Drehmoment auftritt, was dann der Fall ist, wenn die Rast¬ vorsprünge 12 auf den Außenwulst 13 aufgleiten und sich unter Spannung über ihn hinwegbewegen. Dadurch sind die dünnen Stege 10 während des AufSchraubvorganges gegen ein Abscheren oder Abreißen gesichert.When screwing on a screw cap 1 according to FIG. 1 for the first time, the projections 15 shown in FIG. 2 ensure that the locking ring 11 is also taken along without mutual movement when a greater torque occurs, which is the case when the locking projections 12 slide onto the outer bead 13 and move over it under tension. As a result, the thin webs 10 are secured against shearing off or tearing off during the screwing-on process.
Die Vorsprünge 15 brauchen nur an der in Aufschraub¬ richtung gegenüberliegenden Kante der Ausnehmungen 16 an¬ zuliegen, nicht unbedingt jedoch in der entgegengesetzten Richtung, der Abschraubrichtung. Dort, z. B. im Bereich zwischen Flächen 18, 19 und durch gestrichelte Linien an¬ gedeuteten Flächen 20, 21 können dann durch Schraffur an¬ gedeutete Sollbruchstellen 22, 23 angeordnet sein, die dem gleichen Zweck dienen wie die Sollbruchstellen bildenden Stege 10, die dann entfallen können. The projections 15 need only lie against the edge of the recesses 16 opposite in the screwing-on direction, but not necessarily in the opposite direction, the unscrewing direction. There, e.g. B. in the area between surfaces 18, 19 and surfaces 20, 21 indicated by dashed lines, hatching points 22, 23 can then be arranged which serve the same purpose as the webs 10 forming the predetermined breaking points, which can then be omitted .
