Abstract

The screwthread in a screw cap for a bottle has at least one gap which interrupts the screwthread, at a position which is spaced at less than 360 DEG from the start of the screwthread whereby, if the screw cap is fitted in an angled position on to the screwthread on the bottle, the screw cap can snap over the first turn of the screwthread on the bottle in order to move into the proper position.

Description

Die Erfindung betrifft eine KunststoffSchraubkappe für Flaschen, mit einem eingängigen erhabenen Gewinde, das zwischen Gewindeanfang und Gewindeende eine einzige Unterbrechung aufweist, die sich vor Erreichen eines Winkels von 360° gerechnet vom Gewindeanfang (unteres Gewindeende) befindet.The invention relates to a plastic screw cap for bottles, with a catchy raised thread, which has a single interruption between the beginning and end of the thread, which is located before reaching an angle of 360 ° calculated from the beginning of the thread (lower end of the thread).

Bei den bekannten Kunststoff-Schraubkappen für Flaschen besteht die Gefahr, daß beim Aufschrauben der Schraubkappen auf die Flaschen mittels eines Automaten die Schraubkappe auf der Flaschenmündung bzw. auf dem Flaschengewinde schräg zu liegen kommt. Dies ist der Fall, wenn der Gewindeanfang (unteres Gewindeende) der Schraukappe in einem Bereich von 0 bis ca. 180° des Flaschengewindes zu liegen kommt. Dann nämlich kommt das Schraubkappengewinde bei anfänglich in Bezug auf die Flasche ausgerichteter Schraubkappe über weniger als 180° in Anlage mit dem Flaschengewinde, so daß es mit seinem größeren Teil frei über dem Flaschengewinde steht und die Schraubkappe beim Aufsetzen, was ja mit einem gewissen Druck erfolgen muß, kippt bzw. verkantet. Eine auf diese Weise verkantete Schraubkappe wird vom Automaten in dieser verkanteten Stellung beim Aufdrehen festgehalten, so daß eine ordnungsgemäße Schraubverbindung nicht zustande kommt. Mit der Erfindung wird nun die Aufgabe gelöst, hier Abhilfe zu schaffen und eine Schraubkappe der angesprochenen Art derart auszubilden, daß sie vom Automaten ohne weiteres ordnungsgemäß aufgeschraubt werden kann.In the known plastic screw caps for bottles, there is a risk that when the screw caps are screwed onto the bottles by means of an automatic machine, the screw cap will lie obliquely on the bottle mouth or on the bottle thread. This is the case if the thread start (lower thread end) of the screw cap is in a range from 0 to approx. 180 ° of the bottle thread. Then namely the screw cap thread comes into contact with the bottle thread at initially aligned with respect to the bottle over less than 180 °, so that it is freely above the bottle thread with its larger part and the screw cap when put on, which is done with a certain pressure must, tilts or cant. A screw cap tilted in this way is held by the machine in this tilted position when unscrewed, so that a proper screw connection does not come about. With the invention, the problem is solved to remedy this situation and to design a screw cap of the type mentioned in such a way that it can be screwed on properly by the machine without further notice.

Diese Unterbrechung ermöglicht nun ein leichteres Aufweiten des Umfanges der Schraubkappe im Bereich der ersten Gewindewindung, so daß beim Aufsetzen der Schraubkappe innerhalb ei-. nes Drehbereiches, in dem die Schraubkappe ansonsten schräg zu liegen käme, nunmehr unter Aufwand einer geringen Kraft die erste Windung des Gewindes der Schraubkappe über das erste Gewinde des Flaschengewindes überschnappen kann und dadurch die Schraubkappe eben zu liegen kommt und ordnungsgemäß aufgedreht werden kann.This interruption now makes it easier to widen the circumference of the screw cap in the area of the first thread, so that when the screw cap is put on inside. Nes range of rotation, in which the screw cap would otherwise lie obliquely, can now snap over the first turn of the thread of the screw cap over the first thread of the bottle thread with little effort and thereby the screw cap comes to lie flat and can be opened properly.

Vorzugsweise ist die Unterbrechung an einer Stelle vorgesehen, an der die Kraft zum Überschnappen des Schraubkappengewindes über das Flaschenhalsgewinde beim Aufsetzen der Schraubkappe, wenn diese schräg zu liegen kommt, im Mittel am geringsten ist.The interruption is preferably provided at a point at which the force for snapping the screw cap thread over the bottle neck thread when placing the screw cap, when it comes to lie at an angle, is on average the lowest.

Dem liegt folgender Sachverhalt zugrunde. Die größte Schräglage der Schraubkappe wird erreicht, wenn Gewindeanfang auf Gewindeanfang zu liegen kommt. In diesem Fall ist es aber auch bei den bekannten Kunststoff-Schraubkappen relativ leicht möglich, die Schraubkappe durch Überschnappen über das Flaschenhalsgewinde in eine gerade Lage zu überführen, so daß sie ordnungsgemäß aufgeschraubt werden kann. Wird nun von der Stelle, an der die Schraubkappe ihre größte Schräglage einnimmt, die Schraubkappe im Sinne eines Aufschraubens gedreht, so nimmt allnählich die Schräglage entsprechend der Gewindesteigung ab, wobei aber die zum Überschnappen erforderliche Kraft zunimmt, bis sie einen Maximalwert erreicht, um dann wieder abzunehmen. Schließlich liegt die Schraubkappe mit dem größten Teil ihrer ersten Windung auf der ersten Windung des Flaschengewindes auf, so daß eine Schräglage nicht mehr gegeben ist.This is based on the following facts. The greatest inclined position of the screw cap is achieved when the thread start lies on the thread start. In this case, it is also relatively easy with the known plastic screw caps to transfer the screw cap into a straight position by snapping it over the bottle neck thread, so that it can be screwed on properly. If the screw cap is rotated from the point at which the screw cap assumes its largest inclined position, the inclined position gradually decreases in accordance with the thread pitch, but the force required to snap over increases until it reaches a maximum value, and then to take off again. Finally, the screw cap lies with most of its first turn on the first turn of the bottle thread, so that there is no longer an inclined position.

Daher ist es auch zweckmäßig, die Unterbrechung an die Stelle des Schraubkappengewindes zu legen, die vom Schraubkappengewindeanfang so weit entfernt ist, wie die Stelle des Gewindeanfangs der Schraubkappe vom Gewindeanfang der Flasche, wenn die Kraft zum Überschnappen am größten wird.It is therefore also expedient to place the interruption in the place of the screw cap thread which is as far away from the beginning of the screw cap thread as the place where the beginning of the thread of the screw cap is from the beginning of the bottle thread when the force to snap over becomes greatest.

Die oben angesprochenen Stellen lassen sich leicht von Hand nachweisen.The points mentioned above can easily be verified by hand.

Aus den obigen Ausführungen geht hervor, daß, wenn sonst keine weiteren besonderheiten vorliegen, die Stelle, an der die Unterbrechung am Schraubkappengewinde vorgesehen ist, vom Gewindeanfang der Schraubkappe etwa 90° entfernt sein wird.From the above it is clear that, if there are no other special features, the point at which the interruption is provided on the screw cap thread will be approximately 90 ° away from the beginning of the screw cap thread.

Die Gewinde von Schraubkappe und Flasche können mehrere Windungen aufweisen, wobei aber die Unterbrechung immer nur in der ersten Windung des Schraubkappengewindes vorgesehen ist.The threads of the screw cap and bottle can have several turns, but the interruption is always provided only in the first turn of the screw cap thread.

Es sind zwar bereits ähnliche Schraubkappen wie die erfindungsgemäße Schraubkappe bekannt, doch liegen diesen Schraubkappen völlig andere Probleme zugrunde. So handelt es sich beispielsweise bei einer Schraubkappe nach der DE-A-3 006 481 um eine mit einem zweigängigen Gewinde, die so aufgesetzt wird, daß die Gewindeenden von Flaschenhals und Schraubkappe aneinander angrenzen, wobei dann die Schraubkappe vertikal über die Gewindegänge der Flasche geschnappt und in die Endstellung gepreßt wird. Hierbei ergibt sich jedoch nicht das der Erfindung zugrundeliegende Problem und es ist daher auch keine Unterbrechung im Gewinde der Schraubkappe vorgesehen.Screw caps similar to the screw cap according to the invention are already known, but these screw caps are based on completely different problems. For example, a screw cap according to DE-A-3 006 481 is one with a two-start thread, which is placed in such a way that the threaded ends of the bottle neck and screw cap adjoin one another, the screw cap then snapping vertically over the threads of the bottle and is pressed into the end position. However, this does not result in the problem on which the invention is based and therefore there is no interruption in the thread of the screw cap.

Aus US-A-3 402 842 und US-A-1 351 496 sind Kunststoffschraubkappen bekannt, deren Gewinde mehrere Unterbrechungen aufweisen. Hier handelt es sich aber um Schnell- und Sicherheitsverschlüsse, wobei die Unterbrechungen im Gewinde dazu dienen, entsprechende Gewindeabschnitte auf dem Flaschenhals beim Aufsetzen der Schraubkappe hindurchzulassen. Auch hier ist eine völlig andere Aufgabenstellung als bei der Erfindung gegeben.From US-A-3 402 842 and US-A-1 351 496 plastic screw caps are known, the threads of which have several interruptions. However, these are quick-release and safety closures, with the interruptions in the thread serving to allow corresponding thread sections on the bottle neck to pass through when the screw cap is put on. Here, too, the task is completely different from that of the invention.

In der beiliegenden Zeichnung, die zwei Figuren umfaßt, von denen Fig. 1 eine Ansicht von unten auf die offene Seite der Schraubkappe und Fig. einen Schnitt durch die Schraubkappe zeigt, ist die Erfindung nochmals veranschaulicht. Das Gewinde 10 der Schraubkappe mit dem Gewindeanfang 12 ist an der Stelle 14 unterbrochen, wobei die Gewindeenden an der Unterbrechungsstelle 14 wie gezeigt abgeschrägt sind.The invention is illustrated again in the accompanying drawing, which comprises two figures, of which FIG. 1 shows a view from below of the open side of the screw cap and FIG. 1 shows a section through the screw cap. The thread 10 of the screw cap with the The start of thread 12 is interrupted at point 14, the thread ends at the point of interruption 14 being chamfered as shown.
