Abstract

The sealing insert is for bottle caps. The caps are designed so that towards the bottle mouth two or more concentric sealing lips are formed, protruding in the axial direction. The inner sealing lip protrudes inwards further than the outer lip. The inner lip(14b) ends in the axial direction at a flat annular surface (60), at right angles to the axis (A: of the cap(CS), and between inner and outer conical ring faces (56, 58).

Description

Die Erfindung betrifft eine Dichtungseinlage für Verschlußkappen, die auf ihrer dem Behältermüniiungsrand zugewandten Seite mindestens zwei axial vorstehende, konzentrisch angeordnete Dichtlippen aufweisen, von denen die radial innenliegende Dichtlipipe die übrigen Dichtlippen axial überragt, nach Hauptspatent Ϊ4 32 i24.The invention relates to a sealing insert for Closing caps on the edge of the container facing side have at least two axially protruding, concentrically arranged sealing lips, of which the radially inner sealing lip protrudes axially beyond the remaining sealing lips, according to the main patent Ϊ4 32 i24.

Diese Dichtungseinlage gemäß Hauptpatent eignet sich besonders für Standardflaschen, deren öffnungsdurchmesser nur relativ geringe Toleranzen aufweistThis sealing insert according to the main patent is particularly suitable for standard bottles whose opening diameter has only relatively small tolerances

Um die Dichtungseinlage auch für Einwegflaschen, die aus dünnerem Glas bestehen und größere Toleranzen im Öffnungsdurchmesser aufweisen, verwenden zu können, wird in Weiterbildung der Lehre des Hauptpatents vorgeschlagen, daß die innenliegende Dichtlingslippe axial durch eine zwischen den sie radial innen und außen begrenzenden konischen Ringflächen befindliche ebene Ringfläche begrenzt wird, die senkrecht zur Mittelachse der Verschlußkappe angeordnet ist Die radial innenliegende Dichtungslippe besitzt also im Schnitt nicht einen dreieckigen, sondern einen — unsymmetrischen — Trapezquerschnitt Dadurch ist die Dichtungseinlage geeignet auch größere Toleranzen im Öffnungsdurchmesser der Flasche zu überbrücken.In order to also use the sealing insert for one-way bottles, which are made of thinner glass and have larger tolerances in the opening diameter to be able to, it is proposed in further development of the teaching of the main patent that the internal Sealing lip axially through a conical ring surface that delimits it radially on the inside and outside located flat annular surface is limited, which is arranged perpendicular to the central axis of the closure cap The radially inner sealing lip does not have a triangular section, but a an - asymmetrical - trapezoidal cross-section. This means that the sealing insert is also suitable for larger ones To bridge tolerances in the opening diameter of the bottle.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläutertThe invention is explained in more detail below with reference to the drawing

Die Verschlußkappe CS enthält eine Dichtungseinlage 40 mit einer radial außenliegenden Dichtlippe 256 und einer radial innenliegenden, axial vorstehenden Dichtungslippe 146. Diese Dichtungslippe wird radial innenliegend durch eine konische Ringfläche 56 und radial außenliegend durch eine konische Ringfläche 58 und oberhalb, zwischen diesen konischen Ringflächen, durch eine ebene Ringfläche 60 begrenzt die senkrecht zur Mittelachse A der Verschlußkappe CS angeordnet ist Die Breite der Ringfläche 60 ist so bemessen, daß eine sichere Dichtwirkung für Flaschen des gesamten Durchmesserbereichs der oberen öffnung gewährleistet istThe closure cap CS contains a sealing insert 40 with a radially outer sealing lip 256 and a radially inner, axially protruding sealing lip 146. This sealing lip is radially inner by a conical ring surface 56 and radially outside by a conical ring surface 58 and above, between these conical ring surfaces a flat annular surface 60 delimits which is arranged perpendicular to the central axis A of the closure cap CS. The width of the annular surface 60 is dimensioned so that a reliable sealing effect is ensured for bottles of the entire diameter range of the upper opening
