Description

Die Erfindung betrifft eine Dicb.tungseinlage für Verschlußkappen, die auf ihrer dem Behältermündungsrand zugewandten Seite mindestens zwei axial vorstehende, konzentrisch angeordnete Dichtlippen aufweisen, von denen die radial innenliegende Dichtlippe die übrigen Dichtlippen axial überragt, nach Hauptpatent 32 124.The invention relates to a Dicb.tungseinlage for closure caps, which on the edge of the container mouth 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 32 124.
Diese Dichtungseinlage gemäß Hauptpatent eignet sich besonders für Standardflaschen, deren Öffnungsdurchmesser nur relativ geringe Toleranzen aufweist. This sealing insert according to the main patent is particularly suitable for standard bottles, the opening diameter of which 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 Dichtungslippe 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.Around the sealing insert also for single-use bottles, which are made of thinner glass and larger ones Having tolerances in the opening diameter to be able to use, is in development of the teaching of Main patent suggested that the inner sealing lip axially through one between them radially inside and outside delimiting conical annular surfaces located flat annular surface is limited, the The radially inner sealing lip is arranged perpendicular to the central axis of the closure cap therefore does not have a triangular, but an - asymmetrical - trapezoidal cross-section the sealing insert is also suitable for larger tolerances in the opening diameter of the bottle bridge.
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 Dichtun^seinlage 40 mit einer radial außenliegenden. Dichtlippe 25b und einer radial innenliegenden, axial vorstehenden Dichtungslippe i4b. 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 one. Sealing lip 25b and a radially inner, axially protruding sealing lip i4b. This sealing lip is delimited radially on the inside by a conical ring surface 56 and radially on the outside by a conical ring surface 58 and above, between these conical ring surfaces, by a flat ring surface 60 which is arranged perpendicular to the central axis A of the closure cap CS.The width of the ring surface 60 is as follows dimensioned so that a reliable sealing effect for bottles of the entire diameter range of the upper opening is guaranteed
