Description

Die Erfindung betrifft eine Zweikomponentenkartusche nach dem Oberbegriff des Anspruches 1.The invention relates to a two-component cartridge according to the preamble of Claim 1.

Bei Zweikomponentenkartuschen werden die in der Kartusche enthaltenen Komponenten in einer auf die Kartusche aufgesetzten Mischkanüle miteinander vermischt. Üblicherweise sind Kartusche und Mischkanüle über einen lösbaren Bajonettverschluß miteinander verbunden.In the case of two-component cartridges, the components contained in the cartridge are in a mixing cannula placed on the cartridge is mixed together. Usually are Cartridge and mixing cannula connected to each other via a detachable bayonet lock.

Bei der Verwendung dieser Kartuschen und Mischkanülen ergibt sich das Problem, daß bei längeren Arbeitsunterbrechungen nicht nur die Masse aushärtet, die sich in der Mischkanüle befindet, sondern die Aushärtung sich einige Millimeter weit in den Hals der Kartusche fortsetzt, so daß beim Aufsetzen einer neuen Mischkanüle Verstopfungen auftreten bzw. der Halsbereich der Kartusche von ausgehärtetem Material gesäubert werden muß.When using these cartridges and mixing tips, the problem arises that Prolonged work breaks not only cure the mass that is in the mixing tip but the curing is a few millimeters into the neck of the cartridge continues so that blockages occur when the new mixing tip is attached or the The neck area of the cartridge must be cleaned of hardened material.

Um dieses Problem zu lösen, ist es bekannt, die Kartuschen-Austrittsöffnungen in Form von zwei hervorstehenden Röhrchen auszubilden. In diese Röhrchen taucht ein in der Mischkanüle sitzender Einsatz ein, so daß die Aushärtung in der Mischkanüle und dem Mischkanüleneinsatz stattfindet. Beim Entfernen der Mischkanüle wird der Einsatz mit entfernt. Ein Nachteil dieser bekannten Ausführungsform besteht darin, daß durch den Einsatz der Austrittsquerschnitt vermindert wird und somit zum Entleeren der Kartusche erheblicher Druck auf den Kartuschenkolben ausgeübt werden muß.In order to solve this problem, it is known to design the cartridge outlet openings in the form of to form two protruding tubes. Dip into these tubes in the mixing tip a seated insert, so that the hardening in the mixing tip and the Mixing cannula use takes place. When removing the mixing tip, the insert is used away. A disadvantage of this known embodiment is that the use the outlet cross section is reduced and thus more significant for emptying the cartridge Pressure must be exerted on the cartridge piston.

Weiterhin ist nachteilig, daß Mischer und Kartusche nicht der herkömmlichen Ausführung entsprechen und mit diesen somit nicht kompatibel sind. Die herkömmliche Ausführungsform weist ein Röhrchen mit einer Trennwand auf, womit zwei halbmondförmige Austrittsöffnungen gebildet werden.Another disadvantage is that the mixer and cartridge are not of the conventional design correspond and are therefore not compatible with them. The conventional embodiment has a tube with a partition, making two crescent-shaped Outlet openings are formed.

Bei einer zweiten Ausführungsform werden die Kartuschenaustrittsöffnungen gebildet durch zwei im Abstand zueinander angeordneten Bohrungen. Der Einsatz besteht in diesem Fall aus einem weichen Kunststoff und dichtet am Rand der Bohrungen anliegend ab. Bei dieser Ausführungsform muß darauf geachtet werden, daß die durch den Einsatz verlaufenden Kanäle mit den vorerwähnten Bohrungen der Kartusche fluchten. In a second embodiment, the cartridge outlet openings are formed by two holes spaced apart. The stake in this case consists of a soft plastic and seals against the edge of the holes. At this Embodiment must be taken to ensure that those running through the insert Channels are aligned with the aforementioned holes in the cartridge.

Es besteht die Aufgabe, eine Zweikomponentenkartusche so auszubilden, daß bei üblicher Konstruktion der Kartusche eine Mischkanüle herkömmlicher Bauart verwendbar ist, bei welcher eine Vormischung der Materialkomponenten der Kartusche am Eintritt in die Mischkanüle stattfindet.It is the task of designing a two-component cartridge in such a way that with conventional Construction of the cartridge, a mixing cannula of conventional design can be used which is a premixing of the material components of the cartridge at the entrance to the Mixing tip takes place.

Gelöst wird diese Aufgabe mit den Merkmalen des Anspruches 1. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.This problem is solved with the features of claim 1. Advantageous Refinements can be found in the subclaims.

Die Zweikomponentenkartusche 1 weist ein Röhrchen 2 auf, durch das eine Trennwand 3 verläuft, die die Kartusche in zwei Kammern 4 und 5 unterteilt. Durch die Trennwand 3 werden im Röhrchen 2 zwei halbmondförmige Austrittsöffnungen 7, 8 gebildet. The two-component cartridge 1 has a tube 2 through which a partition 3 runs, which divides the cartridge into two chambers 4 and 5. Through the partition 3 two crescent-shaped outlet openings 7, 8 are formed in the tube 2.

Mittels eines Bajonettverschlusses 6 ist auf die Kartusche 1 eine Mischkanüle 9 aufgesetzt. Diese Mischkanüle 9 übergreift mit ihrem unteren Teil einen Einsatz 10. Dieser Einsatz 10 übergreift mit seinem unteren Teil das Röhrchen 2 und sitzt mit seinem unteren Ende auf einer das Röhrchen 2 umgebenden Schulter 11 auf.A mixing cannula 9 is placed on the cartridge 1 by means of a bayonet catch 6. The lower part of this mixing cannula 9 overlaps an insert 10. This insert 10 overlaps tube 2 with its lower part and sits on one with its lower end the tube 2 surrounding shoulder 11.

Die Trennwand 3 weist an ihrem oberen Ende eine Nut 12 auf. In diese Nut 12 greift der Mittelsteg 13 des Einsatzes 10 ein. Dieser Mittelsteg 13 kann bis zum oberen Ende des Einsatzes 10 verlaufen.The partition 3 has a groove 12 at its upper end. In this groove 12 engages Middle web 13 of the insert 10. This central web 13 can be up to the top of the Bet 10 run.

Im gezeigten Ausführungsbeispiel weisen die Durchtrittsöffnungen eine Form auf, die bewirkt, daß die beiden Komponenten der Kammern 4 und 5 bereits beim Eintritt in die Mischkammer 14 der Mischkanüle 9 miteinander vermischt werden.In the exemplary embodiment shown, the passage openings have a shape that causes the two components of the chambers 4 and 5 already when entering the Mixing chamber 14 of the mixing cannula 9 are mixed together.

Von der Austrittsöffnung 7 der Kammer 5 verlaufen zwei seitliche Durchtrittsöffnungen 15 koaxial durch den Einsatz 10 bis an das obere Ende des Einsatzes 10. Von der Austrittsöffnung 8 der Kammer 4 verlaufen zwei weitere Durchtrittsöffnungen 16 koaxial bis zum oberen Ende des Einsatzes 10. Zwischen den Durchtrittsöffnungen 15 und den Durchtrittsöffnungen 16 sind zwei weitere Durchtrittsöffnungen 17, 18 angeordnet. Der untere Eingang der Durchtrittsöffnung 17 kommuniziert mit der Austrittsöffnung 7 der Kammer 5, während der Eingang der Durchtrittsöffnung 18 mit der Austrittsöffnung 8 der Kammer 4 kommuniziert. Die Durchtrittsöffnungen 17, 18 weisen jeweils eine schräg verlaufende Lippe 19, 20 auf, deren Schrägen zueinander entgegengesetzt sind. Hierdurch wird bewirkt, daß der Ausgang der Durchtrittsöffnung 17 am oberen Ende des Einsatzes 10 zwischen den beiden Durchtrittsöffnungen 16 liegt, während der Ausgang der Durchtrittsöffnung 18 zwischen den beiden Durchtrittsöffnungen 15 liegt. Am Eingang der Mischkammer 14 liegt somit ein Materialstrang aus der Kammer 4 zwischen zwei Materialsträngen der Kammer 5 und ein Materialstrang der Kammer 5 zwischen zwei Materialsträngen aus der Kammer 4. Dies bedeutet, daß zwischen den beiden Materialsträngen aus den Durchtrittsöffnungen 15, die mit der Kammer 5 kommunizieren, ein Materialstrang aus der Durchtrittsöffnung 18, die mit der Kammer 4 kommuniziert, austritt. Entsprechendes gilt bezüglich der mit der Kammer 4 kommunizierenden Durchtrittsöffnungen 16 und der mit der Kammer 5 kommunizierenden Durchtrittsöffnung 17. Two lateral passage openings 15 run from the outlet opening 7 of the chamber 5 coaxially through the insert 10 to the top of the insert 10. From the The outlet opening 8 of the chamber 4 extends two further through openings 16 coaxially to the upper end of the insert 10. Between the passage openings 15 and the Through openings 16, two further through openings 17, 18 are arranged. The lower The entrance of the passage opening 17 communicates with the outlet opening 7 of the chamber 5, during the entrance of the passage opening 18 with the outlet opening 8 of the chamber 4 communicates. The passage openings 17, 18 each have an oblique lip 19, 20, the slopes of which are opposite to each other. This causes the Exit of the passage opening 17 at the upper end of the insert 10 between the two Passage openings 16 is located, while the exit of the passage opening 18 lies between the two through openings 15 is located. At the entrance of the mixing chamber 14 is therefore a Material strand from the chamber 4 between two material strands of the chamber 5 and one Strand of material from chamber 5 between two strands of material from chamber 4. This means that between the two strands of material from the openings 15, the the chamber 5 communicate, a strand of material from the passage opening 18, with the Chamber 4 communicates, exits. The same applies to the chamber 4 communicating passage openings 16 and the communicating with the chamber 5 Passage opening 17.

Bei der Ausführungsform nach den Figuren 6 bis 10 sind diejenigen Teile, die mit denjenigen des ersten Ausführungsbeispiels übereinstimmen, mit dem Buchstaben A versehen. Die Trennwand 3A weist wiederum eine Nut 12A auf, in welche das untere Ende des Mittelstegs 13A eingreift. Dieser Mittelsteg 13A erstreckt sich axial durch den Einsatz 10A. Mit der Austrittsöffnung 7A kommuniziert die Durchtrittsöffnung 17A, während mit der Austrittsöffnung 8A die Durchtrittsöffnung 18A kommuniziert. Der untere Teil der Mischkanüle 9A übergreift den Einsatz 10A. Die Durchtrittsöffnung 17A weist einen ersten Ausgang 21 auf. Die Durchtrittsöffnung 18A weist ebenfalls einen ersten Ausgang 22 auf. Die Durchtrittsöffnung 17A umfaßt einen in Umfangsrichtung des Einsatzes 10A verlaufenden Kanal 23, der in einem zweiten Ausgang 21A mündet.

Die Kanäle 23, 24 sind durch radial verlaufende Wandungsteile 26 voneinander getrennt. Deren Enden liegen an der Innenwand des unteren Teils der Mischkanüle 9A an, wobei dieser untere Teil den Einsatz 10A übergreift. Die Kanäle 23, 24 werden außen durch die Innenwand 25 des unteren Teils der Mischkanüle 9A begrenzt. Der Kanal 23 mündet im Ausgang 21A, während der Kanal 24 am Ausgang 22A mündet.In the embodiment according to FIGS. 6 to 10, those parts are the same as those match the first embodiment, provided with the letter A. The Partition 3A in turn has a groove 12A into which the lower end of the central web 13A engages. This central web 13A extends axially through the insert 10A. With the Outlet opening 7A communicates through opening 17A, while with the Exit opening 8A communicates the through opening 18A. The lower part of the Mixing cannula 9A overlaps insert 10A. The passage opening 17A has a first one Exit 21 on. The passage opening 18A also has a first outlet 22. The Passage opening 17A includes a circumferential direction of insert 10A Channel 23, which opens into a second output 21A. The passage opening 18A faces also on a channel 24 extending in the circumferential direction of the insert 10A, which in FIG a second outlet 22A opens. The channels 23, 24 are radial Wall parts 26 separated from each other. Their ends lie on the inner wall of the lower one Part of the mixing cannula 9A, this lower part engaging over the insert 10A. The canals 23, 24 are delimited on the outside by the inner wall 25 of the lower part of the mixing cannula 9A. Channel 23 opens into output 21A, while channel 24 opens into output 22A.

Die sich hierdurch ergebende Konfiguration der Ausgänge 21, 21A und 22, 22A zeigt die Figur 10. Zum Ausgang 21A ist der Ausgang 22A radial nach außen versetzt, während der Ausgang 21 A radial nach außen zum Ausgang 22 versetzt ist. Die Ausgänge 21, 21A kommunizieren mit der Durchtrittsöffnung 17A, während die Ausgänge 22, 22A mit der Durchtrittsöffnung 18A kommunizieren. Diese Ausgänge 21, 21A und 22, 22A sind jeweils kreisabschnittfdrmig ausgebildet, wobei der jeweils radial außen liegende Ausgang 21A, 22A einen größeren Winkelbereich einnimmt als der benachbarte Ausgang 21, 22. Die Kanäle 23, 24 und die zugehörigen Ausgänge 21A und 22A werden jeweils von der Innenwand 25 begrenzt.The resulting configuration of outputs 21, 21A and 22, 22A is shown in FIG Figure 10.
