Description

Schraubkappe mit Innendichtung und FlaschenmUndung Es sind eine Reihe von Schraubverschliissen bekannt, die mit einer lamellenartigen oder rohrstückformigen Innendichtung versehen sind. Bei allen bekannten Ausfiihrungen geht man davon allas, dass der ringförmige, meist konische, Ansatz in der Schraubkappe in die Mundung des Behälters eintaucht und da-aus elastischem Material gefertigt-die Dichtung elastisch si cul an die Flaschenwandung anschmiegt. Diese Ausführungen, die in die Flaschenmündung hinaintauchend, bevorzugen einen steilen Konus. Daneben gibt es eine zweite Hauptru) e die eine sehr flach liegende Ringlamelle vorsehen, die wiederum elastisch gegen die Mündung drückt, Jedoch auf den obersten Rand der Mündung. Bei allen Ausfiihrungen wird aliein die Elastizität des Materials @echnisch als Unsache einer Abdichtung beabsichtigt.Screw cap with inner seal and bottle neck There are a number of them known of screw closures that have a lamellar or tubular piece Inner seal are provided. In all known designs, one assumes all that the ring-shaped, usually conical, approach in the screw cap into the mouth of the container is immersed and there-made of elastic material-the seal is elastic si cul clings to the bottle wall. These designs that go into the bottle mouth diving down, prefer a steep cone. There is also a second main room. e which provide a very flat ring lamella, which in turn is elastic against the mouth presses, however, on the uppermost edge of the mouth. In all versions is considered to be the elasticity of the material @technically as an improper seal intended.

Vorliegende Neuerung sieht demgegenüber eine Verformung des elastischen Kunststoffmaterials vor, die teilweise aus der Blastizität des Naterials, teilweise aus dem kalten Fluß her wirksam wird. Dies wArd dadurch erreicht, dass der ringförmige Schlauchansatz(4) gegen einen Absatz inner@alb der Behältermundung (3) anstoßt, wobei heim Augenblick des Auftreffens auf den Absatz (3) noch eine Vorspannung ( 5 ) vorhanden ist. Beim weiteren aufschrauben der Schraubkappe ( 1 ) gegen die Flaschenn. ündun@ ( 2) entsteht zwangsläufig dje beabsichtigte Verformung (h). Diese gschicht gegen eine konische Fläche der @eh@ltermündung ( 7 ).In contrast, the present innovation sees a deformation of the elastic Plastic material, partly from the blasticity of the material, partly takes effect from the cold river. This is achieved by making the ring-shaped Hose extension (4) hits a shoulder inside the container mouth (3), where at the moment of impact on paragraph (3) there is still a bias ( 5) is present. When you continue to screw on the screw cap (1) against the bottle. ündun @ (2) inevitably results in the intended deformation (h). This gschicht against a conical surface of the @ eh @ lter mouth (7).
