Abstract

The invention relates to a piston for a cartridge (8) with a ring collar (3) that is integrally formed on the piston wall (2) and that is provided with a sealing lip (6). Said ring collar, when not inserted in the cartridge, extends outwardly at an angle with its free end. When inserted, said ring collar is radially deformed in a direction towards the interior and the sealing lip (6) is prestressed to closely fit the cartridge wall (11). When such a piston is inserted in the cartridge, the sealing lip (6) is often damaged, especially if the piston is not inserted sufficiently centrally. The aim of the invention is to provide a piston for a cartridge that is designed in such a manner as to substantially avoid damages to the sealing lip (6). To this end, at the free end the piston land (3) extends beyond the sealing lip (6).

Description

Kolben für eine Kartusche Piston for a cartridge

Die Erfindung betrifft einen Kolben für eine Kartusche nach dem Oberbegriff des Anspruches 1.The invention relates to a piston for a cartridge according to the preamble of claim 1.

Die bekannten Kartuschenkolben weisen einen an der Kolbenwand angeformten Ringsteg auf, dessen äußerer Rand als Dichtlippe ausgebildet ist. Der Ringsteg weist im nicht eingesetzten Zustand mit seinem freiem Ende schräg nach außen. Zwischen dem Ringsteg und dem Kolbenboden besteht ein ringförmiger Spalt V-förmigen Querschnitts. Im in die Kartusche eingesetzten Zustand wird der Ringsteg radial nach innen deformiert, so daß die Dichtlippe unter Vorspannung zur Anlage an die Kartuschenwand kommt.The known cartridge pistons have an annular web molded onto the piston wall, the outer edge of which is designed as a sealing lip. When not in use, the ring web has its free end obliquely outwards. There is an annular gap V-shaped cross-section between the ring land and the piston crown. When inserted into the cartridge, the ring web is deformed radially inward so that the sealing lip comes to bear against the cartridge wall under pretension.

Der Kolben besteht aus einem weichen Kunststoffmaterial, während die Kartusche aus einem dazu härteren Material besteht. Beim Einsetzen des Kolbens in die Kartusche kommt es immer wieder vor, daß die Dichtlippe an den scharfkantigen Rand der Kartusche stößt und hierdurch beschädigt wird. Dies ist insbesondere dann der Fall, wenn das Einsetzen des Kolbens in die Kartusche nicht ausreichend zentrisch erfolgt. Weitere Beschädigungen der Dichtlippe erfolgen beim Transport, da die Kolben aus Kostengründen als Schüttgut in Kartons transportiert werden und sich sowohl beim Transport als auch beim Umfüllen gegenseitig beschädigen können.The piston is made of a soft plastic material, while the cartridge is made of a harder material. When inserting the plunger into the cartridge, it often happens that the sealing lip hits the sharp-edged edge of the cartridge and is thereby damaged. This is particularly the case if the piston is not inserted sufficiently centrally into the cartridge. Further damage to the sealing lip occurs during transport, since the pistons are transported in bulk in cartons for cost reasons and can damage one another both during transport and during decanting.

Diese Beschädigungen der Dichtlippe führen dazu, daß beim Auspressen des Füllmaterials der Kartusche Material zwischen der Kartuschenwand und der Dichtlippe austreten kann.This damage to the sealing lip means that material can escape between the cartridge wall and the sealing lip when the filling material of the cartridge is pressed out.

Es besteht die Aufgabe, den Kolben für eine Kartusche so auszubilden, daß eine Beschädigung der Dichtlippe weitgehend vermieden wird. Gelöst wird diese Aufgabe mit den Merkmalen des Anspruches 1. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.The object is to design the piston for a cartridge in such a way that damage to the sealing lip is largely avoided. This object is achieved with the features of claim 1. Advantageous refinements can be found in the subclaims.

Ausführungsbeispiele werden nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:Exemplary embodiments are explained in more detail below with reference to the drawings. Show it:

Figur 1 einen Schnitt durch den Kolben beim Einsetzen in die Kartusche;Figure 1 shows a section through the piston when inserted into the cartridge;

Figur 2 einen Schnitt bei in die Kartusche eingesetztem Kolben undFigure 2 shows a section with the piston inserted into the cartridge and

Figur 3 einen Schnitt bei einem Ringkolben für eine Zweikomponenten-FIG. 3 shows a section through an annular piston for a two-component

Kartusche.Cartridge.

Der Kolben nach den Figuren 1 und 2 weist einen Kolbenboden 1, eine Kolbenwand 2 und einen an die Kolbenwand 2 angeformten Ringsteg 3 auf. Zwischen dem Ringsteg 3 und dem Kolbenboden 1 wird somit ein ringförmiger Spalt 4 V-förmigen Querschnitss gebildet. Im nicht eingesetzten Zustand gemäß Figur 1 weist der Ringsteg 3 mit seinem freien Ende schräg nach außen, bildet also im Querschnitt gesehen einen Kegelstumpf.The piston according to FIGS. 1 and 2 has a piston head 1, a piston wall 2 and an annular web 3 molded onto the piston wall 2. An annular gap 4 of V-shaped cross-section is thus formed between the ring web 3 and the piston crown 1. In the non-inserted state according to FIG. 1, the ring web 3 points obliquely outwards with its free end, that is, seen in cross section, forms a truncated cone.

An der Außenseite des Ringstegs ist ein rechteckiger Vorsprung 5 angeformt, dessen obere äußere Kante die Funktion einer Dichtlippe 6 aufweist. Der Ringsteg 3 ist an seinem freien Ende über die Dichtlippe hinaus verlängert, wobei diese Verlängerung als Ringrippe ausgebildet ist.A rectangular projection 5 is formed on the outside of the ring web, the upper outer edge of which has the function of a sealing lip 6. The annular web 3 is extended at its free end beyond the sealing lip, this extension being designed as an annular rib.

Wird der Kolben 1 in die Kartusche 8 eingesetzt, dann kommt als erstes der äußere Rand 9 der Ringrippe 7 in Kontakt mit der Einführungsschräge 10 am unteren Rand der Kartusche 8. Beim weiteren Einsetzen wird der Ringsteg 3 radial nach innen deformiert, wobei dann im eingesetzten Zustand die Dichtlippe 6 unter Vorspannung in Kontakt steht mit der Innenwand 11 der Kartusche 8, wie dies die Figur 2 zeigt. Der äußere Rand 9 der Ringrippe 7 befindet sich hierbei im Abstand zur Innenwand 11. Im nicht eingebauten Zustand des Kolbens verläuft die Verbindungslinie 12 zwischen dem äußeren Rand 9 der Ringrippe 7 und der Dichtlippe 6 unter einem spitzen Winkel α zur Einfuhrungsschräge 10 der Kartusche 8. Damit ist gewährleistet, daß stets der äußere Rand 9 in Kontakt tritt mit der Einführungsschräge 10. Die Dichtlippe 6 kommt erst dann mit der Kartuschenwand in Berührung, wenn der Kolben beim Eindrücken in die Kartusche 8 von der konischen Einführungsschräge in den zylindrischen Wandbereich 11 gleitet.If the piston 1 is inserted into the cartridge 8, the outer edge 9 of the ring rib 7 comes first into contact with the insertion slope 10 at the lower edge of the cartridge 8. When it is inserted further, the ring web 3 is deformed radially inward, in which case it is inserted When the sealing lip 6 is in prestressed contact with the inner wall 11 of the cartridge 8, as shown in FIG. 2. The outer edge 9 of the annular rib 7 is located at a distance from the inner wall 11. In the non-installed state of the piston, the connecting line 12 runs between the outer edge 9 of the annular rib 7 and the sealing lip 6 at an acute angle α to the insertion slope 10 of the cartridge 8. This ensures that the outer edge 9 always comes into contact with the insertion slope 10. The sealing lip 6 only comes into contact with the cartridge wall when the piston slides from the conical insertion bevel into the cylindrical wall region 11 when it is pressed into the cartridge 8.

Trotz des vorhandenen Spalts 13 zwischen der Innenwand 11 und der Ringrippe 7 im eingesetzten Zustand des Kolbens ist die Funktion der Dichtlippe 6 beim Auspressen des Füllmaterials voll gewährleistet, da die außenseitige Fläche der Ringrippe 7 wesentlich kleiner ist, als die innenseitige Fläche des Ringstegs 3.Despite the existing gap 13 between the inner wall 11 and the annular rib 7 in the inserted state of the piston, the function of the sealing lip 6 is fully guaranteed when the filling material is pressed out, since the outer surface of the annular rib 7 is considerably smaller than the inner surface of the annular web 3.

Wie die Figur 3 zeigt, ist das vorbeschriebene Prinzip auch anwendbar bei einem Ringkolben für eine Zweikomponenten-Kartusche. Hier ist zusätzlich ein innerer Ringsteg 14 vorgesehen. As shown in FIG. 3, the principle described above can also be applied to an annular piston for a two-component cartridge. An inner ring web 14 is additionally provided here.
