Description

Die Erfindung bezieht sich auf ein Verfahren zum Entleeren von kartuschenartigen Behältern mittels einer den Behälter aufnehmenden, den Behälterumfang abstützenden Pistole, an deren vorderem Ende die am vorderen Ende des Behälters vorgesehene Düse vorsteht sowie die vordere Wand des Behälters abgestützt wird und in deren hinterem Ende ein in Richtung auf das vordere Ende bewegbarer Kolben gehalten ist, sowie auf einen Behälter zur Durchführung des Verfahrens.The invention relates to a method for emptying cartridge-like containers by means of a pistol which holds the container and supports the circumference of the container, at the front end of which protrudes the nozzle provided at the front end of the container and the front wall of the container is supported and in the rear end thereof Piston movable towards the front end is held, as well as a container for performing the method.

Üblicherweise ist in das hintere Ende derartiger kartuschenartiger Behälter ein Verschlußkolben dichtend eingesetzt, der nach Einfügen des Behälters in die zum Entleeren des Behälterinhalts dienende Pistole und Öffnen der Düse, etwa durch Abschneiden der sie verschließenden Spitze, mit Hilfe des Kolbens der Pistole im Behälter nach vorn verschoben wird und dadurch Behälterinhalt aus der Düse herausdrückt. Diese bekannten, kartuschenartigen Behälter sind sehr aufwendig in der Befüllung und in der Herstellung, weil einerseits der Verschlußkolben in einem gesonderten Arbeitsgang nach dem Befüllen eingesetzt werden muß und andererseits der Verschlußkolben mit engen Toleranzen hergestellt und die Behälterwand stabil und maßgenau gefertigt werden muß. Trotzdem besteht die Gefahr, daß bei der Verschiebung des Verschlußkolbens in Richtung auf die Düse zwischen Verschlußkolben und Innenfläche der Umfangswand des Behälters der Behälterinhalt austritt. Ferner kann bei längerer Lagerung des Behälters zwischen Verschlußkolben und Innenfläche der Umfangswand Lösungsmittel oder Weichmacher hindurchtreten, so daß der Behälterinhalt allmählich austrocknet bzw. aushärtet.Usually, a sealing piston is inserted sealingly into the rear end of such cartridge-like containers, which after inserting the container into the pistol used to empty the container and opening the nozzle, for example by cutting off the tip closing it, with the piston's piston is moved forward in the container and thereby pushes the container contents out of the nozzle. These known, cartridge-like containers are very expensive to fill and manufacture, because on the one hand the sealing piston has to be used in a separate operation after filling and on the other hand the sealing piston has to be manufactured with tight tolerances and the container wall has to be manufactured stably and accurately. Nevertheless, there is a risk that the contents of the container will escape when the sealing piston is displaced towards the nozzle between the sealing piston and the inner surface of the peripheral wall of the container. Furthermore, when the container is stored for a long time between the sealing piston and the inner surface of the peripheral wall, solvents or plasticizers can pass through, so that the contents of the container gradually dry out or harden.

Es ist Aufgabe der Erfindung, ein Verfahren zu schaffen, mit dem sich ein wesentlich einfacher herstellbarer kartuschenartiger Behälter entleeren läßt, bei dem nicht die Gefahr des Austritts von Behälterinhalt und/oder Lösungsmittel oder Weichmacher am hinteren Ende des Behälters besteht.It is an object of the invention to provide a method with which a cartridge-type container which can be produced much more easily can be emptied, in which there is no risk of the container contents and / or solvent or plasticizer escaping at the rear end of the container.

Zur Lösung dieser Aufgabe wird ein Verfahren der eingangs erwähnten Art erfindungsgemäß derart ausgestaltet, daß der Kolben bei Bewegung in Richtung auf das vordere Ende der Pistole zur Anlage am geschlossenen hinteren Ende des Behälters kommt und die Umfangswand des Behälters balgförmig zusammendrückt. Vorzugsweise wird dabei ein Behälter mit in Richtung auf sein vorderes Ende plastisch verformbarer Umfangswand verwendet.To achieve this object, a method of the type mentioned is designed according to the invention such that the piston comes to rest against the closed rear end of the container when moving in the direction of the front end of the pistol and compresses the peripheral wall of the container like a bellows. A container with a peripheral wall which is plastically deformable in the direction of its front end is preferably used.

Bei dem erfindungsgemäßen Verfahren wird also ein Behälter eingesetzt, der im hinteren Ende keinen mit hohem Aufwand einzusetzenden Verschlußkolben aufweist, sondern dessen hinteres Ende mit einer Bodenwand verschlossen ist, die fest mit der Umfangswand verbunden ist. Zum Austragen von Behälterinhalt wird der gesamte Behälter vom Kolben der verwendeten Pistole in axiale Richtung zusammengedrückt, so daß die gleiche Wirkung wie mit einem eingesetzten Verschlußkolben erzielt wird, ohne daß die Gefahr besteht, daß am hinteren Ende Behälterinhalt und/oder Lösungsmittel oder Weichmacher austritt.In the method according to the invention, a container is used which does not have a high one in the rear end Has to be used locking piston, but its rear end is closed with a bottom wall which is fixed to the peripheral wall. To discharge the contents of the container, the entire container is compressed in the axial direction by the piston of the pistol used, so that the same effect as with an inserted sealing piston is achieved without the risk of container contents and / or solvent or plasticizer escaping at the rear end.

Ist die Umfangswand des Behälters plastisch verformbar, so sind die Abmessungen des Behälters nach dem Entleeren deutlich verringert, d. h. die Abfallbeseitigung wird vereinfacht.If the peripheral wall of the container is plastically deformable, the dimensions of the container are significantly reduced after emptying, i. H. waste disposal is simplified.

Zur Durchführung des erfindungsgemäßen Verfahrens kann ein Behälter mit einer im wesentlichen zylindrischen Umfangswand, einer am vorderen Ende vorgesehenen Düse und einem verschlossenen hinteren Ende dienen, der sich dadurch auszeichnet, "daß am hinteren Ende eine fest und dichtend mit der Umfangswand verbundene, entsprechend dem Querschnitt der im wesentlichen zylindrischen Umfangswand geformte Bodenwand vorgesehen ist und daß die im wesentlichen zylindrische Umfangswand in Richtung auf das vordere Ende des Behälters zusammendrückbar und vorzugsweise plastisch verformbar ist.To carry out the method according to the invention, a container with an essentially cylindrical peripheral wall, a nozzle provided at the front end and a closed rear end can be used, which is characterized in that "at the rear end a fixed and sealingly connected to the peripheral wall, corresponding to the cross section the substantially cylindrical peripheral wall shaped bottom wall is provided and that the substantially cylindrical peripheral wall is compressible towards the front end of the container and is preferably plastically deformable.

Bei einem derartigen Behälter legt sich der Kolben der Pistole auf die Bodenwand auf und verlagert diese in Richtung auf das vordere Ende des Behälters. Dadurch erfolgt eine gleichmäßige Druckbeaufschlagung der Umfangswand und somit eine gleichmäßige Verformung.In such a container, the pistol of the pistol lies on the bottom wall and shifts it towards the front end of the container. This results in an even pressurization of the peripheral wall and thus a uniform deformation.

Die Umfangswand und die Bodenwand können aus Metall, vorzugsweise aus Aluminium, Blei oder Zinn, oder auch aus mit Aluminium kaschierter Polyethylenfolie bestehen, wobei die Materialstärke 120 /um bis 180 µm, insbesondere 150 /um betragen kann. Die Bodenwand kann durch Bördelung mit der Umfangswand verbunden sein.The peripheral wall and the bottom wall may be made of metal, preferably of aluminum, lead or tin, or also be made of laminated aluminum polyethylene film, wherein the material thickness of 120 / um to 180 .mu.m, in particular 150 / can to be. The bottom wall can be connected to the peripheral wall by flanging.

Bisher ist es praktisch nicht möglich, die beiden Komponenten einer härtbaren Zweikomponentenmasse im richtigen Mengenverhältnis aus einem einzigen kartuschenartigen Behälter auszutragen, weil für jede dieser beiden Komponenten ein gesonderter, von der Pistole zu bewegender Verschlußkolben erforderlich ist. Ein derartiger Behälter ist mit wirtschaftlichem Aufwand nicht herzustellen.So far, it has not been practically possible to dispense the two components of a curable two-component mass in the correct proportions from a single cartridge-type container, because a separate locking piston which is to be moved by the pistol is required for each of these two components. Such a container can not be produced with economic effort.

Mit Hilfe des erfindungsgemäßen Behälters ist es jedoch überraschenderweise möglich, die beiden Komponenten einer derartigen aushärtbaren Zweikomponentenmasse in einem einzigen Behältnis unterzubringen und auf einfache Weise in dem gewünschten Mischungsverhältnis auszutragen. Hierzu kann ein erfindungsgemäßer Behälter eine konzentrische Umhüllung in Form eines Außenbehälters aufweisen, der eine die Düse konzentrisch aufnehmende Behälterdüse hat, wobei zwischen der Umfangswand des Behälters und der Umfangswand des Außenbehälters ein Ringraum gebildet ist. In ein solches Behältnis kann eine der Komponenten in den Behälter und die andere in den zwischen Behälter und Außenbehälter gebildeten Ringraum eingebracht werden, und die beiden Komponenten werden dann beim Herausdrücken in der Behälterdüse zusammengeführt.With the aid of the container according to the invention, however, it is surprisingly possible to accommodate the two components of such a curable two-component composition in a single container and to discharge them in the desired mixing ratio in a simple manner. For this purpose, a container according to the invention can have a concentric casing in the form of an outer container which has a container nozzle which receives the nozzle concentrically, an annular space being formed between the peripheral wall of the container and the peripheral wall of the outer container. In such a container, one of the components can be introduced into the container and the other into the annular space formed between the container and the outer container, and the two components are then brought together in the container nozzle when they are pressed out.

Um die beiden Komponenten herauszudrücken, kann der Außenbehälter eine starre Umfangswand und einen von hinten in diese dichtend eingesetzten, verschiebbaren Verschlußkolben aufweisen, d.h. der Außenbehälter kann die Form einer üblichen, vorstehend beschriebenen Kartusche haben. Bei Verlagerung des Verschlußkolbens in Richtung auf die Behälterdüse wird dann einerseits das im Ringraum zwischen Behälter und Außenbehälter vorhandene pastöse Gut aus der Behälterdüse herausgedrückt, und andererseits drückt der an der Bodenwand des Behälters anliegende Verschlußkolben die Umfangswand des Behälters in Richtung auf die Düse in der vorstehend beschriebenen Weise zusammen.In order to push out the two components, the outer container can have a rigid peripheral wall and one of have in the back of these sealingly inserted, displaceable sealing pistons, ie the outer container can have the shape of a conventional cartridge described above. When the sealing piston is displaced in the direction of the container nozzle, on the one hand the pasty material present in the annular space between the container and the outer container is pressed out of the container nozzle, and on the other hand the sealing piston resting on the bottom wall of the container presses the peripheral wall of the container towards the nozzle in the above described way together.

In einer anderen Ausgestaltung kann der Außenbehälter eine in Richtung auf sein vorderes Ende zusammendrückbare Umfangswand aufweisen, mit deren hinterem Ende fest und dichtend eine Bodenwand verbunden ist, d.h. der Außenbehälter kann in gleicher Weise wie der eigentliche erfindungsgemäße Behälter ausgebildet sein. Wird dann die Bodenwand des Außenbehälters in Richtung auf die Behälterdüse verlagert, so wird die Umfangswand des Außenbehälters in dieser Richtung zusammengedrückt und außerdem die Bodenwand des Behälters durch Anlage der Bodenwand des Außenbehälters in Richtung auf die Düse verlagert.In another embodiment, the outer container can have a circumferential wall that can be compressed in the direction of its front end, with the rear end of which is firmly and sealingly connected to a bottom wall, i.e. the outer container can be designed in the same way as the actual container according to the invention. If the bottom wall of the outer container is then displaced in the direction of the container nozzle, the peripheral wall of the outer container is compressed in this direction and the bottom wall of the container is also displaced in the direction of the nozzle by abutment of the bottom wall of the outer container.

Der Behälter wird im Außenbehälter im wesentlichen durch das im Ringraum zwischen Behälter und Außenbehälter vorhandene pastöse Gut gehalten. Zusätzlich können jedoch im Bereich der vorderen Wand des Behälters in Eingriff mit dem Außenbehälter stehende Stützstreben vorhanden sein, die bei Beaufschlagung der Bodenwand des Behälters mit Druck eine Verlagerung des Behälters in Richtung auf die Behälterdüse und damit ein mögliches Verschließen dieser Düse verhindern. Selbstverständlich müssen diese Stützstreben so ausgebildet sein, daß zwischen ihnen pastöses Gut aus dem Ringraum zwischen Behälter und Außenbehälter hindurchtreten kann.The container is held in the outer container essentially by the pasty material present in the annular space between the container and the outer container. In addition, however, support struts may be present in the area of the front wall of the container in engagement with the outer container, which, when the bottom wall of the container is pressurized, prevent the container from being displaced in the direction of the container nozzle and thus prevent this nozzle from being closed. Self Ver Of course, these support struts must be designed so that pasty material can pass between them from the annular space between the container and the outer container.

Die Erfindung wird im folgenden anhand der Figuren näher erläutert.

  • Figur 2 zeigt im Schnitt ein anderes Ausführungsbeispiel eines kartuschenartigen Behälters.
  • Figur 3 zeigt schematisch und vereinfacht einen Schnitt durch einen kartuschenartigen Behälter mit Außenbehälter.
  • Figur 4 zeigt in einer Darstellung entsprechend Figur 3 ein weiteres Ausführungsbeispiel für einen kartuschenartigen Behälter mit Außenbehälter.
The invention is explained in more detail below with reference to the figures.
  • Figure 1 shows in section and greatly simplified a pistol with a partially compressed container.
  • Figure 2 shows in section another embodiment of a cartridge-like container.
  • Figure 3 shows schematically and simplified a section through a cartridge-like container with an outer container.
  • Figure 4 shows in a representation corresponding to Figure 3, another embodiment of a cartridge-like container with an outer container.

Die in Figur 1 dargestellte Pistole 1 hat ein rohrförmiges Mittelteil 4, auf das ein vorderes Verschlußteil 3 aufgeschraubt ist, durch das sich die Düse 21 eines kartuschenartigen Behälters erstreckt und an den sich die an die Düse 21 anschließende vordere Endwand 22 des Behälters anlegt. Am hinteren Ende des Mittelteils 4 ist ein Anschlußstück 2 angeschweißt, durch das eine Kolbenstange 5 geführt ist, die an ihrem vorderen Ende einen Kolben 6 trägt. Das Anschlußstück weist außerdem einen Handgriff 12 auf, an dem um eine Achse 14 schwenkbar ein Griffhebel 13 befestigt ist.The gun 1 shown in FIG. 1 has a tubular middle part 4 onto which a front closure part 3 is screwed, through which the nozzle 21 of a cartridge-like container extends and against which the front end wall 22 of the container adjoining the nozzle 21 bears. At the rear end of the middle part 4, a connector 2 is welded, through which a piston rod 5 is guided, which carries a piston 6 at its front end. The connector also has a handle 12 on which a handle lever 13 is pivotally attached about an axis 14.

Auf der Kolbenstange 5 sitzt zwischen zwei Querabschnitten des Anschlußstücks 2 eine Verlagerungsbuchse 7, zwischen der und dem vorderen Querabschnitt des Anschlußstücks 2 eine Druckfeder 9 angeordnet ist. Außerdem weist die Verlagerungsbuchse einen schwenkbaren Eingriffshebel 8 auf, der die Verlagerungsbuchse 7 bei Verschwenkung nach vorn auf der Kolbenstange 5 arretiert. Eine an der Außenseite des äußeren Querabschnittes des Anschlußstücks'2 angeordnete Druckfeder wirkt auf einen Arretierhebel 10, der in der gezeigten Stellung eine axiale Bewegung der Kolbenstange 5 verhindert.On the piston rod 5 sits between two cross sections of the connector 2, a displacement bush 7, between which and the front cross section of the connector 2, a compression spring 9 is arranged. In addition, the displacement bushing has a pivotable engagement lever 8, which locks the displacement bushing 7 on the piston rod 5 when it is pivoted forward. A compression spring arranged on the outside of the outer transverse section of the connecting piece 2 acts on a locking lever 10 which prevents axial movement of the piston rod 5 in the position shown.

Zum Einsetzen des Behälters in die Pistole 1 wird das vordere Verschlußteil 3 abgeschraubt und der Behälter von vorn in das rohrförmige Mittelteil eingesetzt. In dieser Lage ist der Kolben 6 in Figur 1 vollständig nach rechts verschoben. Danach wird das Verschlußteil 3 aufgeschraubt und der Behälter durch Kippen der Pistole so weit nach links verlagert, daß seine vordere Endwand 22 am Verschlußteil 3 anliegt. Nun wird die Kolbenstange durch Druck von Hand auf den Endbereich 6 so weit in das Mitteleil 4 hineingeschoben, bis der Kolben 6 an der Bodenwand 23 des Behälters anliegt. Danach wird die Düsenspitze abgeschnitten, so daß Behäl--terinhalt ausgetragen werden kann.To insert the container into the gun 1, the front closure part 3 is unscrewed and the container is inserted into the tubular middle part from the front. In this position, the piston 6 is completely shifted to the right in FIG. 1. Then the closure part 3 is screwed on and the container is displaced to the left by tilting the gun so that its front end wall 22 abuts the closure part 3. Now the piston rod is pushed by hand onto the end region 6 into the central part 4 until the piston 6 bears against the bottom wall 23 of the container. The tip of the nozzle is then cut off so that the contents of the container can be discharged.

Zum Herausdrücken von Behälterinhalt wird'der Griffhebel 13 im Gegenuhrzeigersinn um die Achse 14 verschwenkt, so daß der Arretierhebel 10 freikommt und infolge Drucks der Feder 11 in eine Lage gelangt, in der er die Bewegung der Kolbenstange 5 nicht mehr behindert. Gleichzeitig kommt der Griffhebel 13 mit seinem oberen Ende zur Anlage am Eingriffshebel 8 und verschwenkt diesen derart, daß die Verlagerungsbuchse 7 auf der Kolbenstange 5 arretiert wird, so daß durch weiteres Verschwenken des Griffhebels 13 die Verlagerungsbuchse 7 gegen die Kraft der Feder 9 und damit die Kolbenstange 5 und der Kolben 6 nach links bewegt werden. Diese Bewegung hat ein balgartiges Zusammendrücken der Umfangswand 20 und damit ein Herausdrücken von Behälterinhalt aus der Düse 21 zur Folge.To push out the contents of the container, the handle lever 13 is pivoted counterclockwise about the axis 14, so that the locking lever 10 is released and, due to the pressure of the spring 11, comes into a position in which it no longer obstructs the movement of the piston rod 5. At the same time, the handle lever 13 comes with its upper end to bear on the engagement lever 8 and pivots it in such a way that the displacement bushing 7 is locked on the piston rod 5, so that by further pivoting of the handle lever 13, the displacement bushing 7 against the force of the spring 9 and thus the piston rod 5 and the piston 6 are moved to the left. This movement results in a bellows-like compression of the peripheral wall 20 and thus a pushing out of the container contents from the nozzle 21.

Bei Freigabe des Griffhebels 13 löst sich die durch den Eingriffshebel 8 hervorgerufene Arretierung der Verlagerungsbuchse 7, und die Feder 9 drückt die Verlagerungs- buchse 7 auf der Kolbenstange 5 in die Ausgangsstellung zurück, während das obere Ende des Griffhebels 13 den Arretierhebel 10 wieder gegen die Kraft der Feder 11 in eine die Kolbenstange 5 arretierende Lage verschwenkt.Upon release of the handle lever 13 is caused by the engagement lever 8 locking the shifting sleeve 7 is released and the spring 9 pushes the Verla g erungs- bushing 7 on the piston rod 5 into the initial position, while the upper end of the grip lever 13, the lock lever 10 again pivoted against the force of the spring 11 into a position locking the piston rod 5.

Ein weiteres Zusammendrücken der Umfangswand 20 und damit weiteres Herausdrücken von Behälterinhalt aus der Düse 21 erfolgt durch wiederholtes Verschwenken des Griffhebels 13 mit den vorstehend geschilderten Bewegungsabläufen.A further compression of the peripheral wall 20 and thus further pressing out of the container contents from the nozzle 21 takes place by repeatedly pivoting the handle lever 13 with the movement sequences described above.

Es sei erwähnt, daß das Mittelteil 4 der Pistole 1 nicht unbedingt rohrförmig ausgebildet zu sein braucht. Es kommt lediglich darauf an, daß beim Zusammendrücken der Umfangswand 20 des Behälters ein seitliches Ausknicken verhindert wird, was schon dadurch erreicht werden kann, daß das Mittelteil in Umfangsrichtung verteilt axial verlaufende Streben aufweist.It should be mentioned that the central part 4 of the gun 1 does not necessarily have to be tubular. The only thing that matters is that when the peripheral wall 20 of the container is compressed, a lateral buckling is prevented, which can already be achieved in that the central part has axially extending struts distributed in the circumferential direction.

Der in Figur 2 dargestellte Behälter ist ähnlich dem Behälter gemäß Figur 1 aufgebaut, d. h. er hat eine zylindrische, vorzugsweise kreiszylindrische Umfangswand 20', an deren hinterem Ende eine im wesentlichen die gleiche Querschnittsform wie die Umfangswand 20 aufweisende Bodenwand 23' befestigt ist. Die vordere Endwand 22' geht in eine Düse 21 über, die jedoch in diesem Fall keinen sich verjüngenden Querschnitt, sondern ein Außengewinde hat, auf das ein lösbarer Verschluß aufgeschraubt werden kann.The container shown in FIG. 2 is constructed similarly to the container according to FIG. 1, ie it has a cylindrical, preferably circular-cylindrical peripheral wall 2 0 ', at the rear end of which a substantially the same cross-sectional shape as the peripheral wall 20 has a bottom wall 23' attached. The front end wall 22 'merges into a nozzle 21, which, however, in this case does not have a tapering cross section, but instead has an external thread onto which a releasable closure can be screwed.

Wenn die Umfangswand 20 des Behälters aus Figur 1 bzw. 20' des Behälters aus Figur 2 aus Metall, beispielsweise Aluminium, Blei oder Zinn, oder aus einer mit Aluminium kaschierten Polyethylenfolie bzw. Aluminium-Verbundfolie besteht, läßt sich die entsprechend aufgebaute Bodenwand 23 bzw. 23' auf einfache Weise durch Bördelung am hinteren Ende der Umfangswand befestigen. Außerdem verformt sich eine aus derartigem Material bestehende Umfangswand mit einer Materialstärke von 120 um bis 180 /um beim _Zusammendrücken plastisch, d. h., der entleerte Behälter nimmt als Abfall nur einen sehr geringen Raum ein.If the peripheral wall 20 of the container from FIG. 1 or 20 'of the container from FIG. 2 consists of metal, for example aluminum, lead or tin, or of an aluminum-laminated polyethylene film or aluminum composite film, the correspondingly constructed bottom wall 23 or 23 'simply attach to the rear end of the peripheral wall by flanging. In addition, an existing peripheral wall of such material deformed with a material thickness of 120 to 180 / um at _Zusammendrücken plastically, that is, the empty containers takes as a drop only a very small space.

In Figur 3 ist ein Behälter 100 dargestellt, der im wesentlichen entsprechend dem Behälter gemäß Figur 2 aufgebaut ist, d.h. seine balgartig zusammendrückbare Umfangswand 120 ist am hinteren Ende mit einer Bodenwand 123 dichtend verschlossen und geht am vorderen Ende in eine Düse 121 über. Der Behälter 100 ist koaxial in einen Behälter 101 eingesetzt, der ebenfalls eine balgartig zusammendrückbare Umfangswand 124 hat, die am hinteren Ende mittels einer Bodenwand 126 dichtend verschlossen ist und die am vorderen Ende in eine Behälterdüse 125 übergeht, in die sich die Düse 121 koaxial erstreckt. Auf die Behälterdüse 125 kann eine gestrichelt angedeutete Abdeckkappe 127 aufgesetzt werden.FIG. 3 shows a container 100 which is constructed essentially in accordance with the container according to FIG. its bellows-like compressible peripheral wall 120 is sealed at the rear end with a bottom wall 123 and merges into a nozzle 121 at the front end. The container 100 is inserted coaxially into a container 101, which also has a bellows-like compressible peripheral wall 124 which is sealed at the rear end by means of a bottom wall 126 and which at the front end merges into a container nozzle 125 into which the nozzle 121 extends coaxially . A cover cap 127, indicated by dashed lines, can be placed on the container nozzle 125.

Wird der Behälter 100 mit einer Komponente B und der Ringraum zwischen Behälter 100 und Außenbehälter 101 mit einer Komponente A einer aushärtbaren Zweikomponentenmischung gefüllt und erfolgt dann ein Einsetzen in eine Pistole gemäß Figur 1, so kann die Bodenwand 126 des Außenbehälters 101 mittels des Kolbens 6 der Pistole in Richtung auf die Behälterdüse 125 verlagert werden. Dabei wird die Umfangswand 124 des Behälters 101 sowie infolge Anlage der Bodenwand 126 an der Bodenwand 123 auch die Umfangswand 120 des Behälters 100 in der vorstehend beschriebenen Weise balgartig zusammengedrückt, so daß sowohl die Komponente A als auch die Komponente B durch die Behälterdüse 125 bzw. die Düse 121 herausgedrückt wird.If the container 100 is filled with a component B and the annular space between the container 100 and the outer container 101 is filled with a component A of a curable two-component mixture and then inserted into a pistol according to FIG. 1, the bottom wall 126 of the outer container 101 can be moved by means of the piston 6 Gun are moved towards the container nozzle 125. The peripheral wall 124 of the container 101 and, as a result of the bottom wall 126 abutting the bottom wall 123, the peripheral wall 120 of the container 100 are compressed in the manner described above, so that both component A and component B are pressed through the container nozzle 125 or the nozzle 121 is pushed out.

In einem in Figur 4 dargestellten, abgewandelten Ausführungsbeispiel ist ein im wesentlichen dem Behälter 100 entsprechender Behälter 200, der eine zusammendrückbare Umfangswand 220, eine deren hinteres Ende verschließende Bodenwand 223 und eine an ihrem vorderen Ende vorgesehene Düse 221 hat, in einen Behälter 201 eingesetzt, der eine starre Umfangswand 224 hat, wie dies bei üblichen Kartuschen der Fall ist. Die Düse 221 erstreckt sich in eine Behälterdüse 225. Im Bereich der vorderen Endwand des Behälters 200 sind an diesen Stützstreben 227 angeformt, die sich, wie dargestellt, an einem schrägen Bereich der vorderen Endwand des Außenbehälters 201 abstützen, so daß sie den vorderen Teil des Behälters 200 positionieren und eine Verlagerung in axialer Richtung nach links (in der Figur) verhindern.In a modified exemplary embodiment shown in FIG. 4, a container 200 which essentially corresponds to the container 100 and has a compressible peripheral wall 220, a bottom wall 223 which closes the rear end thereof and a nozzle 221 provided at its front end, is inserted into a container 201, which has a rigid peripheral wall 224, as is the case with conventional cartridges. The nozzle 221 extends into a container nozzle 225. In the region of the front end wall of the container 200 are formed on these support struts 227, which, as shown, are supported on an inclined region of the front end wall of the outer container 201, so that they support the front part of the Position the container 200 and prevent it from moving axially to the left (in the figure).

In den Außenbehälter 201 ist, wie bei Standardkartuschen üblich, dichtend ein Verschlußkolben 226 eingesetzt. Wird dieser Verschlußkolben 226 nach vorn, also in der Figur nach links verlagert, so drückt er das im Ringraum zwischen Behälter 200 und Außenbehälter 201 befindliche pastöse Gut A nach vorn zwischen den Stützstreben 227 hindurch in die Behälterdüse 225. Darüber hinaus kommt der Verschlußkolben 226 zur Anlage an der Bodenwand 223 und verlagert diese in gleicher Weise, wodurch die Umfangswand 220 in der vorstehend beschriebenen Weise balgartig zusammengedrückt und das pastöse Gut B aus der Düse 221 herausgepreßt wird.A sealing piston 226 is sealingly inserted into the outer container 201, as is customary with standard cartridges. If this locking piston 226 is moved forward, that is to say to the left in the figure, it pushes it in Annular space between the container 200 and the outer container 201 located pasty goods A forward between the support struts 227 into the container nozzle 225. In addition, the sealing piston 226 comes to bear against the bottom wall 223 and displaces it in the same way, as a result of which the peripheral wall 220 in the manner described above Compressed like a bellows and the pasty material B is pressed out of the nozzle 221.
