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 gemäß Oberbegriff des Anspruchs 1.The invention relates to a bottle screw cap according to the preamble of claim 1.

Flaschenschraubverschlüsse werden vorzugsweise aus Leichtmetall US-PS 3,812,991 hergestellt und weisen meist ein Innengewinde auf, das in ein Außengewinde eingreift, das an dem zu verschließenden Behälter vorgesehen ist. Ein mit dem Schraubverschluß beziehungsweise dessen Kappe durch Stege verbundener sogenannter Sicherheitsring umschließt einen im Gewindebereich des Behälters angeordneten Absatz derart, daß sich beim ersten öffnen des Flaschenschraubverschlusses der Sicherheitsring verformt und sichtbar beschädigt wird. Diese Verformung beziehungsweise Beschädigung dient dazu, dem Verbraucher erkennenzulassen, daß ein Behälter nach der Abfüllung bereits schon einmal geöffnet wurde.Bottle screw caps are preferably made of light metal US Pat. No. 3,812,991 and mostly have an internal thread that engages in an external thread that is provided on the container to be closed. A so-called safety ring connected to the screw cap or its cap by webs encloses a shoulder arranged in the threaded area of the container in such a way that the safety ring is deformed and visibly damaged when the bottle screw cap is opened for the first time. This deformation or damage serves to show the consumer that a container has already been opened after filling.

In der Praxis hatte sich herausgestellt, daß häufig Handverletzungen auftreten, die durch spanartig abstehende Segmente des Sicherheitsrings, der beim ersten öffnen entlang von Sollbruchlinien aufreißt, verursacht werden, da der festschließende Schraubverschluß insbesondere beim ersten öffnen mit erhöhter Handkraft aufgedreht werden muß.In practice, it had been found that hand injuries often occur, which are caused by the protruding segments of the safety ring, which tears open along predetermined breaking lines when it is first opened, since the tight-fitting screw closure must be unscrewed with increased hand force, particularly when it is first opened.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Flaschenschraubverschluß zu schaffen, der derartige Handverletzungen praktisch ausschließt.The object of the invention is therefore to create a bottle screw cap which practically excludes such hand injuries.

Diese Aufgabe wird bei einem Flaschenverschluß der eingangs genannten Art mit Hilfe der in Anspruch 1 genannten Merkmale gelöst. Dadurch, daß eine den Sicherungsring überlappende Schürze vorgesehen ist, werden Verletzungen an den im Bereich der Sollbruchstellen entstehenden Grate praktisch ausgeschlossen.This object is achieved with a bottle stopper of the type mentioned at the outset with the aid of the features mentioned in claim 1. The fact that an apron overlapping the securing ring is provided prevents injuries to the ridges occurring in the area of the predetermined breaking points.

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 security 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 turned counterclockwise, in such a way that the security ring tears apart at so-called predetermined breaking points.

Dabei stehen die noch mit dem Verschluß 1 durch Stege verbundenen Sicherungsringteile wie Späne vom Flaschenhals ab, die dann bei Unvorsicht durch den Verbraucher Handverletzungen beim Schließ- oder Öffnungsvorgang verursachen können.In this case, the circlip parts still connected to the closure 1 by webs, such as 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.
