Abstract

The cartridge (1) has a piston movable in the cartridge, and a separating wall (12) for dividing the cartridge into a set of chambers. The separating wall is separated from the cartridge for pressing free-flowing masses when the piston is moved in the cartridge. The separating wall runs in a longitudinal direction and is clamped in a transverse direction of the cartridge, where the separating wall is formed as a flexible foil. A foil bag (6) contains components of the free flowing masses, where an area of a wall of the foil bag forms the separating wall.

Description

Die Erfindung betrifft eine Mehrkomponenten-Kartusche mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a multi-component cartridge having the features of the preamble of claim 1.

Solche Kartuschen werden zum Aufbewahren und zum Ausbringen von fließfähigen, beispielsweise pastösen Massen wie beispielsweise Klebern oder Dichtmassen verwendet. Zum Auspressen werden die Kartuschen in Auspresspistolen oder dgl. eingesetzt, die einen Kolben in einer Auspressrichtung in der Kartusche verschieben und dadurch die in der Kartusche enthaltene Masse auspressen.Such cartridges are used for storing and dispensing flowable, for example, pasty masses such as adhesives or sealants. For squeezing the cartridges are used in Auspresspistolen or the like., Which displace a piston in a Auspressrichtung in the cartridge and thereby squeeze out the mass contained in the cartridge.

Die Offenlegungsschrift DE 10 2005 017 599 A1 offenbart eine Zweikomponenten-Kartusche, die in zwei Kammern unterteilt ist, in denen zwei Komponenten einer fließfähigen Masse getrennt voneinander aufbewahrt sind. Die bekannte Kartusche weist eine biegeschlaffe Folie auf, die mit Hilfe von Kernen so in eine Spritzgießform eingelegt wird, dass sie zwei Schläuche mit einer gemeinsamen Trennwand bildet. Die Folie wird mit einem Kunststoff umspritzt, der die Kartusche bildet. Die Folie verbindet sich mit der um sie gespritzten Kartusche, wobei die Trennwand des von der Folie gebildeten Beutels auch in der Kartusche eine Trennwand bildet, die die Kartusche in zwei Kammern unterteilt, die mit den beiden Komponenten befüllt werden. Die beiden Komponenten der fließfähigen Masse können mit einer herkömmlichen Auspresspistole für Einkomponenten-Kartuschen ausgepresst werden, wobei die Trennwand beim Verschieben des Kolbens von der Kartusche getrennt wird. Ein Nachteil der bekannten Zweikomponenten-Kartusche ist die biegeschlaffe Trennwand, die weder feste Kammervolumina noch ein konstantes Auspressverhältnis der beiden Komponenten sicherstellt. Außerdem ist die Herstellung der bekannten Kartusche aufwendig.The publication DE 10 2005 017 599 A1 discloses a two-component cartridge which is divided into two chambers in which two components of a flowable mass are kept separate from each other. The known cartridge has a pliable film which is inserted by means of cores in an injection mold so that it forms two tubes with a common partition. The film is overmolded with a plastic, which forms the cartridge. The film bonds to the cartridge sprayed around it, the partition wall of the bag formed by the film also forming in the cartridge a partition dividing the cartridge into two chambers which are filled with the two components. The two components of the flowable mass can be pressed with a conventional Einpresspistole for one-component cartridges, wherein the partition is separated during displacement of the piston from the cartridge. A disadvantage of the known two-component cartridge is the pliable partition which ensures neither fixed chamber volumes nor a constant Auspressverhältnis the two components. In addition, the production of the known cartridge is expensive.

Aufgabe der Erfindung ist, eine verbesserte Mehrkomponenten-Kartusche vorzuschlagen.The object of the invention is to propose an improved multi-component cartridge.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Die erfindungsgemäße Mehrkomponenten-Kartusche weist mindestens eine Trennwand auf, die in der Kartusche gespannt ist und die Kartusche in Kammern unterteilt. Eine Trennwand unterteilt die Kartusche in zwei Kammern, durch mehr als eine Trennwand sind mehr als zwei Kammern möglich. Dadurch, dass die Trennwand in der Kartusche gespannt ist, bewegt sie sich nicht quer in der Kartusche, so dass die Kammern ein festes Volumen haben und beim Auspressen die Komponenten in konstantem Verhältnis ausgepresst werden. Bei Berücksichtigung von Elastizität ist eine Änderung der Kammervolumina und des Auspressverhältnis möglich, allerdings ist die Änderung für die allermeisten Anwendungsfälle ohne Weiteres akzeptabel. Beim Auspressen trennt der in der Kartusche verschobene Kolben die Trennwand von der Kartusche. Wenngleich die Erfindung mit einer mehr oder weniger steifen Trennwand möglich ist, so ist sie doch an sich für eine biegeschlaffe Folie als Trennwand vorgesehen, weil ein Spannen einer steifen Trennwand nicht notwendig ist und eine steife Trennwand der Verschiebung des Kolbens einen hohen Widerstand entgegensetzt, der das Auspressen erschwert.This object is achieved by the features of claim 1. The multi-component cartridge according to the invention has at least one partition which is tensioned in the cartridge and subdivides the cartridge into chambers. A partition divides the cartridge into two chambers, more than one partition allows more than two chambers. The fact that the partition wall is stretched in the cartridge, it does not move transversely in the cartridge, so that the chambers have a fixed volume and the components are pressed in a constant ratio during pressing. Taking into account elasticity, a change of the chamber volumes and the Auspressverhältnis is possible, however, the change for most applications is readily acceptable. When squeezing the displaced in the cartridge piston separates the partition from the cartridge. Although the invention with a more or less rigid partition wall is possible, it is in itself intended for a pliable foil as a partition, because a clamping of a rigid partition wall is not necessary and a rigid partition of the displacement of the piston opposes a high resistance, the the pressing difficult.

Erfindungsgemäß verläuft die Trennwand in einer Längsrichtung der zylindrischen Kartusche, die Trennwand ist in einer Sehnenebene der Kartusche gespannt und teilt die Kartusche in Kammern mit über die Länge konstanten Querschnitten. Die Trennwand ist in einer Querrichtung der Kartusche gespannt, eine Spannung auch in Längsrichtung ist möglich.According to the invention, the dividing wall extends in a longitudinal direction of the cylindrical cartridge, the dividing wall is stretched in a chordal plane of the cartridge and divides the cartridge into chambers with cross-sections that are constant over the length. The partition is stretched in a transverse direction of the cartridge, a tension in the longitudinal direction is possible.

Eine Ausgestaltung der Erfindung sieht einen Folienbeutel vor, der eine Komponente der fließfähigen Masse enthält. Ein Bereich einer Wand des Folienbeutels ist als Trennwand in der Kartusche gespannt. Es können auch mehrere Folienbeutel vorhanden sein, beispielsweise für jede Komponente der fließfähigen Masse ein Folienbeutel. Auch ist ein Mehrkammer-Folienbeutel möglich, der mehrere, vorzugsweise schlauchförmige Kammern mit gemeinsamer Trennwand bzw. gemeinsamen Trennwänden aufweist, die in der Kartusche gespannt sind.An embodiment of the invention provides a film bag containing a component of the flowable mass. An area of a wall of the film bag is stretched as a partition wall in the cartridge. There may also be a plurality of foil bags, for example a foil bag for each component of the flowable mass. Also, a multi-chamber foil bag is possible, which has a plurality of, preferably tubular chambers with a common partition or common partitions, which are stretched in the cartridge.

Die Befestigung der Trennwand kann beispielsweise durch Schweißen oder Kleben erfolgen, ein Schweißen ist auch von außen durch die Kartusche hindurch denkbar. Ein Folienbeutel, der einen Bereich aufweist, der die in der Kartusche gespannte Trennwand bildet, kann flächig oder auch entlang von Linien oder linienförmigen Streifen dort mit der Kartusche verbunden werden, wo die Trennwand gegen die Kartusche stößt. Eine Ausgestaltung der Erfindung sieht mindestens einen, vorzugsweise zwei nach außen abstehende Streifen des Folienbeutels vor, die mit der Kartusche verbunden werden. Zu diesem Zweck kann der Folienbeutel zu einem oder zwei gedoppelten Streifen gefalzt werden. Eine andere Möglichkeit ist, den Folienbeutel aus zwei Folien herzustellen, die streifenförmig zu dem Beutel miteinander verbunden werden, wobei die verbundenen Folienstreifen den nach außen abstehenden Streifen des Folienbeutels bilden.The attachment of the partition can be done for example by welding or gluing, welding is also conceivable from the outside through the cartridge. A foil pouch, which has a region which forms the dividing wall stretched in the cartridge, can be connected to the cartridge, flat or even along lines or line-shaped strips, where the dividing wall abuts against the cartridge. A Embodiment of the invention provides at least one, preferably two outwardly projecting strips of the film bag, which are connected to the cartridge. For this purpose, the film bag can be folded into one or two duplicated strips. Another possibility is to produce the film bag from two films, which are connected in strips to the bag, wherein the connected film strips form the outwardly projecting strips of the film bag.

Eine Ausgestaltung der Erfindung sieht ein steifes Kopfstück mit einem Auslass, beispielsweise einer rohrförmigen Düse, für die im Folienbeutel enthaltene Komponente der fließfähigen Masse vor. Der Folienbeutel kann mit dem Kopfstück beispielsweise verklebt oder verschweißt sein. Diese Ausgestaltung der Erfindung ermöglicht einen biegeschlaffen und damit dünnwandigen Folienbeutel und ein steifes Kopfstück. "Steif" im Sinne der Erfindung bedeutet nicht absolut starr, sondern schließt eine Elastizität des Kopfstücks ein. Das Kopfstück sollte so steif sein, dass es sich insbesondere beim Auspressen der Masse nicht so stark verformt, dass das Auspressen beeinträchtigt wird.An embodiment of the invention provides a rigid head piece with an outlet, for example a tubular nozzle, for the component of the flowable mass contained in the film bag. The foil bag can be glued or welded to the head piece, for example. This embodiment of the invention allows a pliable and thus thin-walled foil bag and a rigid head piece. "Stiff" in the sense of the invention does not mean absolutely rigid, but includes an elasticity of the head piece. The head should be so stiff that it does not deform so much, especially during the pressing of the mass, that the squeezing is impaired.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

Das Kopfstück 11 befindet sich auf einer Innenseite der Stirnwand 2, es ist mit dem Folienbeutel 6 verschweißt oder in anderer Weise verbunden. Das Kopfstück 11 einschließlich seines Auslass 5 besteht aus einem steifen Kunststoff, es behält seine Form bei.Concentrically in the outlet 3, a likewise tubular outlet 5 of a foil bag 6 located in the cartridge 1 is arranged. The outlet 5 is one of double-walled, so hollow head piece 11 from which has the shape of a circle segment in front view. The head piece 11 is located on an inner side of the end wall 2, it is welded to the film bag 6 or otherwise connected. The head 11 including its outlet 5 is made of a rigid plastic, it retains its shape.

Der Folienbeutel 6 ist aus zwei biegeschlaffen Folien 7, 8 zusammengesetzt und wird, wie in Figur 2 zu sehen, auf einem Kern 9 hergestellt, dessen Querschnitt eine zum Kopfstück 11 kongruente Kreissegmentform aufweist. Die beiden Folien 7, 8 sind gleich lang und unterschiedlich breit. Die eine Folie 7 wird zylinderschalenförmig um eine zylindrische Fläche des Kerns 9 gelegt, die andere auf eine ebene Seite des Kerns 9. Die Folien 7, 8 sind so breit, dass sie über Längskanten des Kerns 9 überstehen, die überstehenden Streifen 10 der Folien 7, 8 werden miteinander verklebt, verschweißt oder in anderer Weise verbunden. Die überstehenden Streifen 10 der Folien 7, 8 bilden nach außen abstehende Streifen 10 des Folienbeutels 6, den die beiden miteinander verbundenen Folien 7, 8 bilden. Die Streifen 10 verlaufen in Längsrichtung des Folienbeutels 6 entlang von Längskanten des Kerns 9. Auf ein Ende des Kerns 9 wird das Kopfstück 11, das an seiner dem Auslass 5 gegenüberliegenden Seite offen ist, an einem Ende auf den Kern 9 aufgesetzt und mit Querrändern der den Folienbeutel 6 bildenden Folien 7, 8 verklebt, verschweißt oder in anderer Weise verbunden.The film bag 6 is composed of two pliable films 7, 8 and is, as in FIG. 2 can be seen, produced on a core 9, whose cross section has a congruent to the head piece 11 segmental circle shape. The two films 7, 8 are the same length and different widths. One film 7 is placed in the form of a cylindrical shell around a cylindrical surface of the core 9, the other on a flat side of the core 9. The films 7, 8 are so wide that they protrude over longitudinal edges of the core 9, the protruding strips 10 of the films. 7 , 8 are glued together, welded or otherwise connected. The protruding strips 10 of the films 7, 8 form outwardly projecting strips 10 of the film bag 6, which form the two interconnected films 7, 8. The strips 10 extend in the longitudinal direction of the film bag 6 along longitudinal edges of the core 9. On one end of the core 9, the head 11, which is open at its outlet 5 opposite side, placed at one end on the core 9 and with transverse edges of the the film bag 6 forming films 7, 8 glued, welded or otherwise connected.

Der auf dem Kern 9 befindliche Folienbeutel 6 wird mit dem Kopfstück 11 voraus von hinten in die Kartusche 1 eingebracht, so dass sich der Auslass 5 des Folienbeutels 6 konzentrisch im Auslass 3 der Kartusche 1, das Kopfstück 11 auf einer Innenseite der Stirnwand 2 der Kartusche 1 und die breitere Folie 7 des Folienbeutels 6 zylinderschalenförmig auf einer Innenseite der Kartusche 1 befinden. Die nach außen vom Folienbeutel 6 abstehenden Streifen 10 werden auf der Innenseite der Kartusche 1 befestigt, beispielsweise verklebt oder verschweißt. Denkbar und möglich ist ein Verschweißen von außen beispielsweise mit Ultraschall.The film bag 6 located on the core 9 is introduced from the rear into the cartridge 1 with the head piece 11, so that the outlet 5 of the film bag 6 concentrically in the outlet 3 of the cartridge 1, the head 11 on an inner side of the end wall 2 of the cartridge 1 and the wider film 7 of the film bag 6 are cylindrical shell-shaped on an inner side of the cartridge 1. The outwardly projecting from the film bag 6 strips 10 are mounted on the inside of the cartridge 1, for example, glued or welded. Conceivable and possible is a welding from the outside, for example, with ultrasound.

Der Folienbeutel 6 wird so auf dem Kern 9 hergestellt und die Streifen 10 werden so in der Kartusche 1 befestigt, dass die Folie 8 auf der ebenen Seite des Kerns 9 gespannt ist und nach dem Herausziehen des Kerns 9 gespannt bleibt. Die Folie 8 bildet eine Trennwand 12, die in einer Längsebene der Kartusche 1 gespannt ist und die Kartusche 1 in zwei Kammern unterteilt. Eine der beiden Kammern weist einen kreissegmentförmigen Querschnitt auf, die andere Kammer nimmt den Restquerschnitt ein. Nach dem Herausziehen des Kerns 9 werden die beiden Kammern der Kartusche 1 mit zwei Komponenten einer fließfähigen Masse, beispielsweise mit einem Binder und einem Härter eines Harzes bzw. Klebstoffs, befüllt. Das hintere, dem Kopfstück 11 ferne Ende des Folienbeutels 6 kann nach dem Befüllen zusammengedrückt und verschlossen werden, beispielsweise durch Kleben, Schweißen oder mit einem Clip (nicht dargestellt). Da die Folie 8 des Folienbeutels 6, die die Trennwand 12 der Kartusche 1 bildet, in der Kartusche 1 gespannt ist, ist es möglich, die beiden Komponenten nacheinander in die beiden Kammern der Kartusche 1 zu füllen. Durch ihre Spannung wölbt sich die Trennwand 12 nur wenig und die Volumina der beiden Kammern ändern sich kaum.The film bag 6 is thus produced on the core 9 and the strips 10 are secured in the cartridge 1, that the film 8 is stretched on the flat side of the core 9 and remains tensioned after pulling out of the core 9. The film 8 forms a partition 12, which is stretched in a longitudinal plane of the cartridge 1 and the cartridge 1 divided into two chambers. One of the two chambers has a circular segment-shaped cross section, the other chamber takes the remaining cross section one. After pulling out the core 9, the two chambers of the cartridge 1 are filled with two components of a flowable mass, for example with a binder and a hardener of a resin or adhesive. The rear, the head piece 11 far end of the film bag 6 can be compressed after filling and sealed, for example by gluing, welding or with a clip (not shown). Since the film 8 of the film bag 6, which forms the partition wall 12 of the cartridge 1, is tensioned in the cartridge 1, it is possible to successively fill the two components in the two chambers of the cartridge 1. Due to their tension, the partition wall 12 bulges only slightly and the volumes of the two chambers hardly change.

Ausgepresst wird die Kartusche 1 in gleicher Weise, wie es von Einkomponenten-Kartuschen bekannt ist, die nicht in Kammern unterteilt sind: die Kartusche 1 wird in eine Auspresspistole oder dgl. eingelegt, die einen Kolben aufweist, der in die Kartusche 1 verschiebbar ist (nicht dargestellt). Der Kolben verdrängt die Komponenten aus den beiden Kammern der Kartusche 1 durch die beiden Auslässe 3, 5, d.h. der nicht dargestellte Kolben presst die Komponenten aus der Kartusche 1 aus. Mit einem auf das Gewinde 4 des Auslass 3 der Kartusche 1 aufgeschraubten, nicht dargestellten Statikmischer können die beiden Komponenten gemischt werden. Beim Verschieben in der Kartusche 1 trennt der nicht dargestellte Kolben den Folienbeutel 6 von der Kartusche 1 und faltet oder knüllt ihn auf seiner der Stirnwand 2 zugewandten Vorderseite zusammen. Das Trennen des Folienbeutels 6 von der Innenseite der Kartusche 1 erfolgt zugleich mit der Verschiebung des Kolbens, der Kolben trennt den Folienbeutel 6 auf seiner Verschiebelänge von der Innenseite der Kartusche 1. Da die von der einen Folie 8 des Folienbeutels 6 gebildete Trennwand 12 in der Kartusche 1 gespannt ist, ist das Verhältnis der ausgepressten Mengen der beiden Komponenten konstant, es entspricht dem Querschnittsverhältnis der beiden Kammern der Kartusche 1. Es können für jede Komponente der in der Kartusche 1 aufzubewahrenden, fließfähigen Masse ein Folienbeutel 6 in die Kartusche 1 eingebracht und in ihr befestigt werden (nicht dargestellt). Das gilt grundsätzlich für mehr als zwei Komponenten. Bereiche der Folienbeutel 6, die eine Trennwand 12 bilden, werden wie beschrieben in Sehnenebenen der Kartusche 1 gespannt in der Kartusche 1 befestigt.The cartridge 1 is pressed in the same way as is known from single-component cartridges which are not subdivided into chambers: the cartridge 1 is inserted into an ejection gun or the like which has a piston which is displaceable into the cartridge 1 ( not shown). The piston displaces the components from the two chambers of the cartridge 1 through the two outlets 3, 5, i. the piston, not shown, presses the components out of the cartridge 1. With a screwed onto the thread 4 of the outlet 3 of the cartridge 1, not shown static mixer, the two components can be mixed. When moving in the cartridge 1, the piston, not shown, separates the foil bag 6 from the cartridge 1 and folds or crumples it on its front wall 2 facing the front side together. The separation of the film bag 6 from the inside of the cartridge 1 at the same time with the displacement of the piston, the piston separates the film bag 6 on its displacement length from the inside of the cartridge 1. Since the formed by a film 8 of the film bag 6 partition 12 in the Cartridge 1 is stretched, the ratio of the extruded amounts of the two components is constant, it corresponds to the cross-sectional ratio of the two chambers of the cartridge 1. It can be for each component of the stored in the cartridge 1, flowable mass a foil bag 6 is inserted into the cartridge 1 and to be fixed in it (not shown). This basically applies to more than two components. Portions of the foil pouches 6, which form a dividing wall 12, are clamped in the cartridge 1, as described, in tendon planes of the cartridge 1.

Die nach außen vom Folienbeutel 6 abstehenden Streifen 10 sind nicht zwingend für die Befestigung des Folienbeutels 6 in der Kartusche 1 notwendig. Auch ist ein nahtloser, insbesondere schlauchloser Folienbeutel verwendbar (nicht dargestellt). An einem nahtlosen Folienbeutel können in Längsrichtung verlaufende, nach außen vom Folienbeutel abstehende Streifen zur Befestigung des Folienbeutels in der Kartusche 1 durch Längsfaltungen des Folienbeutels hergestellt werden, die streifenförmige Doppelungen der Wand des Folienbeutels bilden. Die die Streifen bildenden Doppelungen werden geklebt, geschweißt oder in sonstiger Weise verbunden.The outwardly projecting from the film bag 6 strips 10 are not mandatory for the attachment of the film bag 6 in the cartridge 1 is necessary. Also, a seamless, in particular tubeless foil bag can be used (not shown). On a seamless foil bag can run longitudinally, outward from Foil bag protruding strip for attachment of the film bag in the cartridge 1 are produced by longitudinal folds of the film bag, which form strip-shaped duplications of the wall of the film bag. The doublings forming the strips are glued, welded or otherwise connected.

Figur 3 zeigt einen Zweikammer-Folienbeutel 6. Er besteht aus einer Folie 7, die um zwei Kerne 9, 13 gelegt ist. Der eine Kern 9 hat die Kreissegmentform des in Figur 2 gezeigten Kerns 9, der andere Kern 13 ergänzt den Kern 9 zu einer Zylinderform. Die Folie 7 ist zwischen den ebenen Flächen der beiden Kerne 9, 13 hindurch geführt und anschließend um beide Kerne 9, 13 herum gelegt. Die ebenen Flächen der Kerne 9, 13 liegen unter Zwischenlage der Folie 7 aneinander an. Auf einer Seite der Kerne 9, 13 steht ein Streifen 14 der Folie 7 vor, der zur Bildung des Zweikammer-Folienbeutels 6 mit dem um die Kerne 9, 13 herumgelegten Teil der Folie 7 verklebt, verschweißt oder in anderer Weise verbunden wird. Auf der anderen Seite überlappt ein Längsrandstreifen 15 der Folie 7 den zwischen den beiden Kernen 9, 13 vortretenden und um die Kerne 9, 13 herumgelegten Teil der Folie 7 und wird ebenfalls durch Kleben, Schweißen oder in sonstiger Weise verbunden. Der Zweikammer-Folienbeutel 6 kann außerhalb der Kartusche 1 hergestellt werden. Denkbar ist eine Herstellung in der Kartusche 1, wenn die Folie 7 in beschriebener Weise zwischen den Kernen 9, 13 hindurchgeführt und um sie herumgelegt ist und mit den Kernen 9, 13 in die Kartusche 1 eingebracht wird. Das Verkleben des Streifens 14 und des überlappenden Längsrandstreifens 15 auf der gegenüberliegenden Seite der Kerne 9, 13 kann beispielsweise durch Ultraschallschweißen von außen durch die Kartusche 1 hindurch erfolgen, wodurch zugleich die beiden Streifen 14, 15 mit der Kartusche 1 verschweißt werden, so dass der zwischen den Kernen 9, 13 befindliche Teil der Folie 7, der die Trennwand 12 bildet, in der Kartusche 1 gespannt ist. Der Zweikammer-Folienbeutel 6 aus Figur 3 weist keine nach außen abstehenden Streifen zu seiner Befestigung in der Kartusche 1 auf, was allerdings nicht ausgeschlossen ist. FIG. 3 shows a two-chamber film bag 6. It consists of a film 7, which is placed around two cores 9, 13. The one core 9 has the circular segment shape of in FIG. 2 shown core 9, the other core 13 complements the core 9 to a cylindrical shape. The film 7 is guided between the flat surfaces of the two cores 9, 13 and then placed around both cores 9, 13 around. The flat surfaces of the cores 9, 13 lie with the interposition of the film 7 to each other. On one side of the cores 9, 13 is a strip 14 of the film 7, which is glued to the formation of the two-chamber film bag 6 with the around the cores 9, 13 lying around part of the film 7, welded or otherwise connected. On the other hand, a longitudinal edge strip 15 of the film 7 overlaps the part of the film 7 projecting between the two cores 9, 13 and around the cores 9, 13 and is likewise joined by gluing, welding or in some other way. The two-chamber foil bag 6 can be produced outside the cartridge 1. It is conceivable manufacture in the cartridge 1, when the film 7 in the manner described between the cores 9, 13 passed and placed around them and is introduced with the cores 9, 13 in the cartridge 1. The gluing of the strip 14 and the overlapping longitudinal edge strip 15 on the opposite side of the cores 9, 13 can for example be carried out by ultrasonic welding from the outside through the cartridge 1, whereby at the same time the two strips 14, 15 are welded to the cartridge 1, so that the between the cores 9, 13 located part of the film 7, which forms the partition wall 12, is stretched in the cartridge 1. The two-chamber foil bag 6 off FIG. 3 has no outwardly projecting strips for its attachment in the cartridge 1, which is not excluded.

Figur 4 zeigt einen aus einer Folie 7 hergestellten Folienbeutel 6. Die Folie 7 ist um einen Kern 9 gelegt, der wieder einen kreissegmentförmigen Querschnitt aufweist. Die Folie 7 ist um die zylinderförmige und ebene Fläche des Kerns 9 herumgelegt, so dass entlang einer Längskante des Kerns 9 zwei Streifen 14 abstehen, die miteinander verschweißt, verklebt oder in sonstiger Weise verbunden werden. Die Streifen 14 bilden einen seitlich überstehenden Streifen 10, mit dem der Folienbeutel 6 in der Kartusche 1 befestigt wird. Auf der anderen Seite des die Trennwand 12 bildenden Bereichs der Folie 7 weist der Folienbeutel 6 aus Figur 4 keinen nach außen stehenden Streifen auf, er wird dort an der Innenseite der Kartusche 1 anliegend mit ihr verbunden. FIG. 4 shows a film bag 6 produced from a film 7. The film 7 is placed around a core 9, which again has a circular segment-shaped cross section. The film 7 is placed around the cylindrical and flat surface of the core 9, so that along a longitudinal edge of the core 9 two strips 14 protrude, which are welded together, glued or connected in any other way. The strips 14 form a laterally projecting strip 10, with which the film bag 6 is mounted in the cartridge 1. On the other side of the dividing wall 12 forming portion of the film 7, the film bag 6 from FIG. 4 no outward strip, he is there connected to the inside of the cartridge 1 fitting with her.
