Abstract

The circular cap (1), preferably consisting of lightweight metal or plastic, has a circumferential inwardly beaded skirt (4) which overlaps the webs (2) of the securing ring (3). <IMAGE>

Description

Die Erfindung betrifft einen Flaschenschraubverschluß mit Fingerschürze.The invention relates to a bottle screw cap with a finger apron.

Flaschenverschlüsse werden vorzugsweise aus Leicht­metall oder Kunststoff hergestellt und weisen meist ein Innengewinde auf, das auf ein am Flaschenhals eingegossenes Außengewinde aufgedreht wird. Ein soge­nannter, mit dem Schraubverschluß durch Stege ver­bundener Sicherheitsring umschließt dabei einen am Flaschenhals angeordneten Absatz derart, daß der Flaschen­verschluß beim Öffnen, d.h. beim Drehen des Verschlusses entgegen dem Uhrzeigersinn, der Sicherheitsring verformt und sichtbar beschädigt wird. Dieses Auftreten ist beabsichtigt, um zu erkennen, ob die Flasche nach der Verfüllung geöffnet wurde.Bottle caps are preferably made of light metal or plastic and usually have an internal thread that is screwed onto an external thread cast on the bottle neck. A so-called safety ring connected to the screw cap by webs encloses a shoulder arranged on the bottle neck in such a way that the bottle cap when opened, i.e. when turning the lock counterclockwise, the safety ring is deformed and visibly damaged. This occurrence is intended to identify whether the bottle was opened after backfilling.

Die Praxis hat gezeigt, daß häufig Handverletzungen auf­treten, die durch die spanartig abstehenden Abreiß­stege verursacht werden, da der fest schließende Schraubverschluß mit erhöhter Handkraft aufgedreht werden muß.Practice has shown that hand injuries often occur, which are caused by the tear-off protruding webs, since the tightly closing screw cap must be unscrewed with increased hand force.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Schraubverschluß bereitzustellen, der Handverletzungen eingangs beschriebener Art ausschließt und dabei den genormten und erforderlichen Ansprüchen gerecht wird.The invention is therefore based on the object of providing a screw closure which excludes hand injuries of the type described in the introduction and thereby standardized and necessary requirements.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Flaschenschraubverschluß mit Fingerschürze dadurch gekennzeichnet ist, daß der kreisförmige, vorzugsweise aus Leichtmetall oder Kunststoff bestehende Schraubverschluß eine umlaufende nach innen umgebördelte, die Stege des Sicherungsringes überlappende Schürze aufweist.This object is achieved in that the bottle screw cap with a finger apron is characterized in that the circular, preferably made of light metal or plastic screw cap has a circumferential flanged skirt that overlaps the webs of the locking ring.

Die Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the accompanying drawing.

Figur 1 zeigt eine Ansicht mit Halbschnitt eines erfindungsgemäßen Flaschenschraubverschlusses 1.FIG. 1 shows a view with a half section of a bottle screw cap 1 according to the invention.

Der Sicherheitsring 3, der mit dem Schraubverschluß 1 durch Stege 2 verbunden ist, wird beim Öffnen der Flasche, also bei Verdrehen des Verschlusses 1 entgegen dem Uhrzeigersinn derart verformt, daß der Sicherheits­ring an sogenannten Sollbruchstellen auseinanderreisst.The safety ring 3, which is connected to the screw cap 1 by webs 2, is deformed when the bottle is opened, that is to say when the cap 1 is rotated counterclockwise, in such a way that the safety ring tears apart at so-called predetermined breaking points.

Dabei stehen die noch mit dem Verschluß 1 durch Stege verbundenen Sicherungsringteile wie Späne vom Flaschen­ hals ab, die dann bei Unvorsicht durch den Verbraucher Handverletzungen beim Schließ- oder Öffnungsvorgang verursachen können.Here are still with the closure 1 connected by webs retaining ring parts like chips from the bottle neck, which can cause hand injuries when closing or opening if the consumer is not careful.

Auch nach dem Abbiegen und Entfernen des Sicherheits­rings 3 verbleibt ein Grad am Verschlußdeckel 1, der gleichfalls eine Verletzungsgefahr darstellen kann.Even after the safety ring 3 has been bent and removed, a degree remains on the closure cover 1, which can likewise pose a risk of injury.

Bei der vorliegenden Erfindung sind die geschilderten Verletzungsgefahren gänzlich ausgeschlossen. Dies wird durch die nach innen umgebördelte umlaufende Finger­schürze 4 gewährleistet, die den Sicherheitsring 3 überlappt, so daß dieser nicht mehr wie früher als Span hervortreten kann.In the present invention, the described risk of injury is completely eliminated. This is ensured by the inwardly flanged circumferential finger apron 4, which overlaps the safety ring 3, so that it can no longer emerge as a chip as before.

Die Erfindung stellt eine wesentliche Verbesserung der Flaschenschraubverschlüsse dar und schützt den Verbraucher wirksam vor den geschilderten Verletzungen.The invention represents a significant improvement in bottle screw caps and effectively protects the consumer from the injuries described.
