Description
Schraubkappe fürfschx-` ü. dgl. Verschlüsse Es gibt Schraubkappen für Flaschen- u. dgl. Verschlüsse mit einem schraubengängigen Einsatzblech, das in das Nippelgewinde des Flaschenmundes oder des Ausgußstutzens des Gefäßes eingreift. Dieses Einsatzblech hat wie eine gewöhnliche Schraubkappe ein durch Rollen erzeugtes Rundgewinde, so daß es leicht überdreht werden und sich lockern kann.Screw cap for fschx-`ü. Like closures There are screw caps for bottle and the like. Closures with a screw-thread insert sheet that engages in the nipple thread of the bottle mouth or the pouring spout of the vessel. Like an ordinary screw cap, this insert sheet has one produced by rolling Round thread so that it can easily be overtightened and loosened.
Dieser Nachteil soll durch die Erfindung vermieden werden, die darin besteht, daß das Einsatzblech anstatt mit einem gebräuchlichen Muttergewinde mit einer Schraubenfläche versehen ist, die sich auf einen ganzen Gewindegang erstreckt und von einer parallel zum Kappenboden verlaufenden Schulter -des Einsatzbleches ausgepreßt ist.This disadvantage is to be avoided by the invention, which consists in the fact that the insert sheet is provided with a screw surface instead of a common female thread, which extends over an entire thread and is pressed out from a shoulder running parallel to the cap base - of the insert sheet.
Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt, und zwar zeigen Fig. i das Einsatzblech im Schaubild, Fig.2 einen Grundriß der Schraubkappe, von unten gesehen, mit dem drehfest gehaltenen Einsatzblech, Fig.3 einen senkrechten Schnitt nach der Linie II-I-III der Fig. 2 und Fig.4 einen senkrechten Schnitt nach der Linie IV-IV der Fig. 2 (Schraubkappe auf dem Nippelgewinde).The drawing shows an embodiment of the invention, namely Fig. 1 shows the insert sheet in the diagram, Fig. 2 a plan view of the screw cap, seen from below, with the insert sheet held in a rotationally fixed manner, FIG. 3 a vertical one Section along the line II-I-III of FIGS. 2 and 4, a vertical section the line IV-IV of Fig. 2 (screw cap on the nipple thread).
Der Kappenteil hat im Flansch seines Mantels 14 radial liegende Auspressungen, welche zur drehfesten Verbindung mit dem Einsatzblech und als Griffe der Schraubkappe dienen.The cap part has 14 radially located press-outs in the flange of its shell, which are used for non-rotatable connection with the insert sheet and as handles of the screw cap to serve.
Das Einsatzblech besteht aus einem Mantel 13, dessen radiale Flanschlappen 15 in die vorgenannten Auspressungen im Flansch des Kappenmantels 14 eingreifen und dessen zwischen den Lappen 15 liegende Flanschteile durch den umgebördelten Rand des Flansches des Kappenmantels 14 festgehalten werden.The insert sheet consists of a jacket 13, the radial flange tabs of which 15 engage in the aforementioned press-outs in the flange of the cap shell 14 and its flange parts lying between the tabs 15 by the flanged Edge of the flange of the cap shell 14 are held.
Vom unteren Ende 16 des Mantels 13 des Einsatzbleches ist ein Flachring abgeschultert, der zu einer über einen ganzen Gewindegang 11, 12, i ,-,a sich erstreckenden geschlitzten Schraubenfläche ausgepreßt ist, deren Innenrand in das Gewinde des Nippels eingreift (Fig. 4).From the lower end 16 of the jacket 13 of the insert sheet is a flat ring shouldered to form a whole thread 11, 12, i, -, a extending slotted screw surface is pressed, the inner edge of which into the thread of the Nipple engages (Fig. 4).
Beim festen Anziehen der Schraubkappe verringert sich die Steigung der Schraubenfläche des Einsatzbleches und damit deren Innendurchmesser, wodurch sich der Innenrand der Schraubenfläche an das Gewinde des Nippels anpreßt und die Sicherung der Lage der Schraubkappe am Gewindenippel erreicht wird. Überdies ist bei der geschlitzten Schraubenfläche auch eine ungleichmäßige Formänderung möglich, wodurch ein dichter Abschluß auch bei unebenem Rande des Gewindenippels erzielt wird.When the screw cap is tightened firmly, the slope is reduced the screw surface of the insert sheet and thus its inner diameter, whereby the inner edge of the screw surface is pressed against the thread of the nipple and the Securing the position of the screw cap on the threaded nipple is achieved. Moreover is An uneven change in shape is also possible with the slotted screw surface, whereby a tight seal is achieved even with an uneven edge of the threaded nipple will.
