Abstract

The cap has a locking ring shearing off the first time it is unscrewed, joined to it by a shear lug and having internal teeth engaging with external ones on the bottle neck. Between the neck (2) and the locking ring (4) of the cap (1) a separate coupling ring (8) is inserted, having lugs on the underside engaging between the radial lugs (5) on the neck. This ring has saw-teeth round the outer periphery, engaging when the cap is screwed home with mating internal teeth (6) of the locking ring. The design allows the bottle to be delivered with the cap on and the coupling ring sent separately, thus preventing dirt getting inside before filling. After filling, the coupling ring is fitted in place and the cap screwed home to form a seal guaranteeing that the contents have not been tampered with.

Description

Schraubkappe Die Erfindung betrifft eine als Originalverschluß verwendbare Schraubkappe aus Kunststoff für Behälter mit einem während des ersten Abschraubvorganges abscherbaren Sicherungsring, der eine dem mit Außenverzahnung versehenen Behälter-Ausgußstutzen zugekehrte Innenverzahnung aufweist und über Abreißstege mit der Schraubkappe verbunden ist. Screw cap The invention relates to one which can be used as an original closure Plastic screw cap for containers with one during the first unscrewing process Shearable locking ring, which is one of the container spout with external teeth Has facing internal teeth and connected to the screw cap via tear-off bars is.

Bei den bekannten Schraubkappen vorstehender Art ist es nicht möglich, den fertigen Behälter vom hersteller verschlossen an den Abfüller zu liefern. Behälter und Schraubkappe werden getrennt versandt, so daß während des Tranaports Schmutz in den Behälter gelangen kann. Es ist auch nicht möglich, derartige Originalverschlüsse als Normalverschlüsse zu verwenden, denn die Verriegelungselemente bilden mit der Schraubkappe eine Einheit.With the known screw caps of the above type, it is not possible The manufacturer delivers the finished container to the bottler in a sealed state. container and screw cap are shipped separately, so that dirt during the Tranaport can get into the container. It is also not possible to use such original closures to use as normal closures, because the locking elements form with the Screw cap one unit.

Man hat diese Nachteile damit zu beheben versucht, indem am izchraubkappenunterrand ein getrennter Sicherungsring befestigt wurde. Die Montage ist Jedoch umstiindlich und zeitraubend. Auch ist der Sicherungsring störanfällig und kann brechen, ohne du die Kappe geöffnet wurde.Attempts have been made to remedy these disadvantages by adding on the lower edge of the screw cap a separate circlip has been attached. However, the assembly is cumbersome and time consuming. The locking ring is also prone to failure and can break without you opened the cap.

Diese Nachteile worden durch die Erfindung dadurch vermieden, daß zwischen Behälterstutzen und Sicherungsring der Schraubkappe ein getrennter Kupplungsring eingelegt ist, der nit an seiner Unterseite angeordneten Nocken zwischen die radial nach außen gerichteten Nocken der Außenverzahnung des Behälterstutzens eingreift und mit seinem sägezahnförmig ausgebildeten Außenumfang bei zugeschraubter Schraubkappe in die entsprechend geformte Innenverzahnung des Sicherungsringes einrastet.These disadvantages have been avoided by the invention in that a separate coupling ring between the container nozzle and the locking ring of the screw cap is inserted, the nit arranged on its underside cam between the radially engages outwardly directed cam of the external toothing of the container nozzle and with its sawtooth-shaped outer circumference when the screw cap is screwed on engages in the correspondingly shaped internal toothing of the locking ring.

Die mit einem getrennten Kupplungsring ausgerüstete Schraubkappe kann vom Verpakungshersteller zur Auslieferung an den Abfüller fest auf dem Behälterstutzen aufgeschraubt werden. Der Kupplungsring wird gesondert mitgeliefert. In diesem lall wirkt der Verschluß als Normalverschlu Soll der Normalverschluß in einen gegen unbefugtes Offnen gesicherten UriginalverschluB verwandelt werden, wird der Kupplungsring mit seinen Nocken in einfacher Weise zwischen die Nocken der Außenverzahnung des Behälterstutzens lose eingelegt und die Schraubkappe zugeschraubt. Am Ende des Schraubweges gleitet die Innenterzahnung des Sicherungsringes über die schwach geneigten Zahnflanken des sägezahnförmigen Außenumfanges des Kupplungsringes und rastet hinter die senkrecht sur Ringachse stehenden Stirnflanken ein. Beim Aufschrauben der Kappe wird der Sicherungsring über den Kupplungsring unverdrehbar am Behälter festgehalten, so daß die den Sicherungsring nit der Kappe verbindenden Abreißstege brechen.The screw cap equipped with a separate coupling ring can from the packaging manufacturer for delivery to the filler firmly on the container nozzle be screwed on. The coupling ring is supplied separately. In this lall the lock acts as a normal lock When the original lock is opened, the coupling ring is transformed with it its cam in a simple manner between the cams of the external toothing of the container nozzle loosely inserted and screwed on the screw cap. Slides at the end of the screwing path the internal teeth of the locking ring over the slightly inclined tooth flanks of the sawtooth-shaped outer circumference of the coupling ring and locks behind the perpendicular on the ring axis standing end flanks. When the cap is screwed on, the locking ring held non-rotatably on the container via the coupling ring, so that the locking ring Break the tear-off bars connecting the cap.

In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt.In the drawing, an embodiment of the invention is for example shown.

Es zeigen: Fig.1 den Behälter-Ausgußstutzen mit aufgeschraubter Kappe tu Längsschnitt. Die linke Hälfte zeigt die Schraubkappe mit eingelegtem Kupplungsring als Originalverschluß, die rechte Hälfte als Normalverschluß ohne Kupplungsring, Fig.2 eine Draufsicht auf die Schraubkappe nach Fig.1 zur Hälfte iu Querschnitt, Fig, 3 den Kupplungsring im Längsschnitt und Fig. 4 den Kupplungsring in der Unteransicht .They show: FIG. 1 the container pouring spout with the cap screwed on do longitudinal section. The left half shows the screw cap with the coupling ring inserted as the original lock, the right half as a normal lock without coupling ring, FIG. 2 is a plan view of the screw cap according to FIG. 1, half in cross section, Fig, 3 shows the coupling ring in a longitudinal section and FIG. 4 shows the coupling ring in a view from below .

Zum Versand vom Verpackungshersteller zum Abfüller wird die Schraubkappe 1, an deren Außenumfang die Griffleisten 11 und an deren Xappenunterrand der Sicherungsring 4 über die radial nach außen gerichteten Abreißstege 7 angeformt sind, ohne eingelegten Kupplungsring auf dem Behälterstutzen 2 aufgeschraubt .The screw cap is used for shipping from the packaging manufacturer to the filler 1, the grip strips 11 on the outer circumference and the locking ring on the lower edge of the Xappen 4 are formed on the radially outwardly directed tear-off webs 7, without inserted Coupling ring screwed onto container nozzle 2.

Somit besteht keine Verbindung &wischen den Nocken 5 der Außenyerzahnung des Behälterstutsens 2 und der Innenverzahnung 6 des Sicherungsringes 4. Die Schraubkappe 1 kann ollne Abscherung des Sicherungsringes 4 abgeschraubt werden.So there is no connection & wipe the cams 5 of the external teeth of the container stub 2 and the internal toothing 6 of the locking ring 4. The screw cap 1 can be unscrewed ollne shear of the locking ring 4.

Erst nach Einlegen des Kupplungsringes 8 nach beendeter Behälterfüllung wird der Originalverschluß hergestellt. Dabei treten die Nocken 10 an der Unterseite des Kupplungsringes 8 in die Zwischenräume zwischen den Nocken 5 der Außenversahnung ein, so daß der Sicherungsring 4 unverdrehbar auf dem Behälter 3 gehalten ist.Only after inserting the coupling ring 8 after the container has been filled the original closure is produced. The cams 10 occur on the underside of the coupling ring 8 in the spaces between the cams 5 of the external teeth a, so that the locking ring 4 is held on the container 3 so that it cannot rotate.

Beim Verschrauben der Kappe 1 gleitet die Innenverzahnung 6 des Sicherungsringes 4 über die in Zuschraubrichtung schwach geneigten Zahnflanken der Sägezähne 9 am Außenumfang des Kupplungsringes 6 und rasten vor die Stirnflanken ein.When the cap 1 is screwed on, the internal toothing 6 of the locking ring slides 4 over the slightly inclined tooth flanks of the saw teeth 9 am in the screwing direction Outer circumference of the coupling ring 6 and snap into place in front of the front flanks.

Statt einer sägezahnförmigen Gestaltung des Kupplungsringes 8 können an dessen Außenumfang auch schräg geneigte Sperrzungen angeformt sein.Instead of a sawtooth-shaped design of the coupling ring 8 can on the outer circumference of which there is also obliquely inclined locking tongues.
