Abstract

A cartridge body (11) contains a piston (14) which can be advanced in order to press the plastic mass contained in the cartridge body out of a discharge neck (13). At the rear end of the cartridge body (11), there are inwardly directed sawtooth-shaped projections (20) which allow the insertion of the piston (14) into the cartridge body (11) with elastic deformation but prevent the return movement of the piston (14). In this manner, the return movement of the piston is blocked without mounting or deformation operations still having to be carried out after the insertion of the piston (14) into the cartridge body (11). <IMAGE>

Description

Die Erfindung betrifft eine Kartusche für plastische Massen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a cartridge for plastic materials according to the preamble of patent claim 1.

Es ist bekannt, plastische Massen, die als Dichtungs­mittel, Klebemittel o.dgl. verwendet werden, in Kartuschen aus Kunststoff unterzubringen. Diese Kartuschen bestehen aus einem zylindrischen Kartuschen­körper, in dem ein Kolben verschiebbar untergebracht ist. Am vorderen Ende des Kartuschenkörpers befindet sich eine Austrittsöffnung, durch die die plastische Masse beim Vorschieben des Kolbens ausgepreßt wird. Das Vorschieben des Kolbens erfolgt mit einem Auspreß­werkzeug, in das die Kartusche eingesetzt wird.It is known plastic or the like as a sealant, adhesive or the like. used to accommodate plastic cartridges. These cartridges consist of a cylindrical cartridge body in which a piston is slidably housed. At the front end of the cartridge body there is an outlet opening through which the plastic mass is squeezed out when the piston is pushed forward. The plunger is pushed forward with an extrusion tool into which the cartridge is inserted.

Derartige Kartuschen sind am rückwärtigen Ende offen, damit der Kolben in das rückwärtige Ende eingeführt werden kann. Im Lagerzustand verschließt der Kolben das rückwärtige Ende des Kartuschenkörpers abdichtend und die Austrittsöffnung ist verschlossen, damit keine Luft in Kartusche eindringt und die darin enthaltende Masse zum Aushärten bringt.Such cartridges are open at the rear end so that the plunger can be inserted into the rear end. The piston closes this in storage condition sealing rear end of the cartridge body and the outlet opening is closed so that no air penetrates into the cartridge and causes the mass contained therein to harden.

Eine Schwierigkeit bei derartigen Kartuschen besteht darin, den Kolben am Herausgleiten aus dem rückwärtigen Ende des Kartuschenkörpers zu hindern. Zu diesem Zweck ist es bekannt, am rückwärtigen Ende ein Verschlußteil anzubringen, das nach dem Einbringen des Kolbens auf­gesetzt wird und das Zurückbewegen des Kolbens ver­hindert. Ein derartiges Verschlußteil stellt einen zu­sätzlichen Aufwand dar und erhöht die Kosten der Kartusche. Eine weitere Möglichkeit besteht darin, das rückwärtige Ende des Kartuschenkörpers nach dem Ein­bringen des Kolbens nach innen umzulegen, so daß ein einwärtsgerichteter Rand entsteht, der einen Anschlag für den Kolben bildet. Hierbei ist es jedoch erforder­lich, einen thermischen Verformungsvorgang nach dem Einbringen des Kolbens am Kartuschenkörper vorzunehmen, was einen erheblichen Aufwand erfordert.A difficulty with such cartridges is to prevent the plunger from sliding out of the rear end of the cartridge body. For this purpose, it is known to attach a closure part at the rear end, which is placed after the piston has been inserted and prevents the piston from moving back. Such a closure part represents an additional effort and increases the cost of the cartridge. Another possibility is to fold the rear end of the cartridge body inwards after the piston has been introduced, so that an inward edge is formed which forms a stop for the piston. Here, however, it is necessary to carry out a thermal deformation process after inserting the piston on the cartridge body, which requires considerable effort.

Der Erfindung liegt die Aufgabe zugrunde, eine Kartusche der im Oberbegriff des Patentanspruchs 1 an­gegebenen Art zu schaffen, die ein Herausbewegen des Kolbens aus dem Kartuschenkörper auf einfache Weise verhindert, die Montage des Kolbens aber nicht er­schwert, und die einfach und kostengünstig herstellbar ist, wobei nach dem Einbringen des Kolbens keine weiteren Montage- oder Umformvorgänge erforderlich sind.The invention has for its object to provide a cartridge of the type specified in the preamble of claim 1, which prevents the piston from moving out of the cartridge body in a simple manner, but does not complicate the assembly of the piston, and which is simple and inexpensive to produce, wherein no further assembly or forming operations are required after the piston has been inserted.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im kennzeichnenden Teil des Patentanspruchs 1 an­gegebenen Merkmalen.This object is achieved according to the invention with the features specified in the characterizing part of patent claim 1.

Bei der erfindungsgemäßen Kartusche sind am rück­wärtigen Ende des Kartuschenkörpers nach innen ge­richtete Vorsprünge angeordnet, an denen der Kolben bei seinem Einführen in den Kartuschenkörper unter elastischer Verformung entlangbewegt werden kann. Diese Vorsprünge, die dem Kartuschenkörper bei dessen Her­stellung bereits angeformt werden, gestatten zwar das Einschieben des Kolbens bei einigem Kraftaufwand, ver­hindern aber, daß der Kolben aus dem Kartuschenkörper austreten kann. Nach dem Befüllen des Kartuschenkörpers mit der plastischen Masse wird der Kolben in das rück­wärtige Ende des Kartuschenkörpers eingeschoben. Dieser Kolben besteht vorzugsweise aus Kunststoff mit einer gewissen Elastizität, so daß er sich beim Passieren der Vorsprünge verformen kann. Zweckmäßigerweise sind die Umfangsteile des Kolbens, die mit den Vorsprüngen in Berührung kommen, nach hinten abgeschrägt, so daß der Kolben leicht über die Vorsprünge überschnappen kann. Andererseits wird durch die nach hinten abgeschrägten Umfangsteile des Kolbens erreicht, daß der Kolben die Vorsprünge in Gegenrichtung nicht passieren kann, sondern sich an diesen Vorsprünge verhakt, so daß er nach dem Einbringen in den Kartuschenkörper diesen Kar­tuschenkörper nicht mehr zerstörungsfrei verlassen kann.In the cartridge according to the invention, inwardly directed projections are arranged at the rear end of the cartridge body, against which the piston can be moved with elastic deformation when it is inserted into the cartridge body. These projections, which are already molded onto the cartridge body during its manufacture, allow the piston to be pushed in with some effort, but prevent the piston from escaping from the cartridge body. After filling the cartridge body with the plastic mass, the plunger is inserted into the rear end of the cartridge body. This piston is preferably made of plastic with a certain elasticity, so that it can deform when passing through the projections. The circumferential parts of the piston which come into contact with the projections are expediently beveled to the rear, so that the piston can easily snap over the projections. On the other hand, the circumferential parts of the piston, which are chamfered towards the rear, ensure that the piston cannot pass the projections in the opposite direction, but hooks onto these projections, so that it can no longer leave this cartridge body without being destroyed after it has been introduced into the cartridge body.

Die Vorsprünge können grundsätzlich als nach innen ge­richtete Verdickungen der Wand des Kartuschenkörpers ausgebildet sein, jedoch handelt es sich vorzugsweise um sickenartige Deformierungen der Zylinderwand, die ursprünglich eine über die Länge konstante Stärke hat, jedoch in einem nachträglichen Verformungsvorgang nach innen deformiert bzw. ausgebeult ist.The projections can in principle be designed as inward thickening of the wall of the cartridge body, but it is preferably a bead-like deformation of the cylinder wall, which originally has a constant thickness over the length, but is deformed or bulged inwards in a subsequent deformation process.

Gemäß einer bevorzugten Ausführungsform der Erfindung haben die Vorsprünge sägezahnförmige Gestalt, die das Passieren des Kolbens in Vorwärtsrichtung ermöglicht, das Zurückziehen jedoch blockiert. Die Vorsprünge können aus jeweils an einen Umfangsschlitz angrenzenden Deformierungsabschnitt bestehen.According to a preferred embodiment of the invention, the projections have a sawtooth shape, which allows the piston to pass in the forward direction, but blocks the retraction. The projections can each consist of a deformable section adjoining a circumferential slot.

Obwohl der Kolben normalerweise eine gewisse Elastizi­tät hat um beim Einschieben in den Kartuschenkörper vorübergehend deformiert zu werden, haben auch die Vor­sprünge bzw. die Wand des Kartuschenkörpers eine Elastizität. Ob beim Einschieben des Kolbens in den Kartuschenkörper überwiegend der Kolben oder der Kar­tuschenkörper nachgibt, ist gleichgültig. Wichtig ist, daß der Kolben unter elastischer Verformung des Kolbens und/oder des Kartuschenkörpers in den Kartuschenkörper eingeschoben werden kann und danach abdichtend an der Wand des Kartuschenkörpers anliegt.Although the piston normally has a certain elasticity in order to be temporarily deformed when it is inserted into the cartridge body, the projections or the wall of the cartridge body also have an elasticity. It does not matter whether the piston or the cartridge body mainly yields when the piston is pushed into the cartridge body. It is important that the piston can be pushed into the cartridge body with elastic deformation of the piston and / or of the cartridge body and then lies sealingly against the wall of the cartridge body.

Im folgenden wird unter Bezugnahme auf die einzige Figur der Zeichnung ein Ausführungsbeispiel der Er­findung näher erläutert.In the following, an embodiment of the invention will be explained in more detail with reference to the single figure of the drawing.

In der Zeichnung ist ein Längsschnitt einer Kartusche dargestellt.In the drawing, a longitudinal section of a cartridge is shown.

Die Kartusche 10 weist einen zylindrischen Kartuschen­körper 11 aus Kunststoff auf. Der Kartuschenkörper 11 ist mit einer einstückig angeformten Frontwand 12 ver­sehen. An der Frontwand 12 ist ein mit Gewinde ver­sehener Auslaßstutzen 13 angeordnet, in dem sich die Austrittsöffnung befindet.The cartridge 10 has a cylindrical cartridge body 11 made of plastic. The cartridge body 11 is provided with an integrally molded front wall 12. On the front wall 12, a threaded outlet nozzle 13 is arranged, in which the outlet opening is located.

In den Kartuschenkörper 11 ist der Kolben 14 ein­gesetzt. Dieser Kolben 14 weist eine zylindrische Um­fangswand 15 mit davon abstehenden, schräg nach hinten gerichteten kontinuierlichen Umfangsrippen 16 auf. Die Frontwand 17 des Kolbens 14 ist bogenförmig gewölbt und in ihrer Mitte mit einer Spitze 18 versehen. Die Um­fangswand 15 und die Frontwand 17 begrenzen den nach hinten offenen Hohlraum 19 des Kolbens 14. In diesen Hohlraum wird das Vorschuborgan eines (nicht darge­stellten) Auspreßwerkzeugs eingeführt, in das die Kar­tusche 10 eingesetzt werden kann, um den Kartuschen­inhalt aus dem Auslaßstutzen herauszudrücken.The piston 14 is inserted into the cartridge body 11. This piston 14 has a cylindrical circumferential wall 15 with continuous circumferential ribs 16 projecting therefrom and directed obliquely to the rear. The front wall 17 of the piston 14 is arched and provided with a tip 18 in the middle. The peripheral wall 15 and the front wall 17 delimit the rearwardly open cavity 19 of the piston 14. In this cavity, the feed member of an extrusion tool (not shown) is inserted, into which the cartridge 10 can be inserted in order to press the cartridge contents out of the outlet nozzle.

Am rückwärtigen Ende des Kartuschenkörpers 11 sind drei gleichmäßig über den Umfang verteilt angeordnete, nach innen gerichtete Vorsprünge 20 angeordnet, von denen in der Zeichnung nur zwei sichtbar sind. Jeder Vorsprung 20 grenzt an einen Schlitz 21 an, wobei der hinter dem Schlitz 21 angeordnete Bereich der Wand des Kartuschen­körpers 11 nach innen gedrückt ist und den Vorsprung 20 bildet. Die Vorsprünge 20 haben auf diese Weise säge­zahnförmige Gestalt, wobei die nach vorne gerichtete Flanke 22 die Begrenzung des Schlitzes 21 darstellt und eine Anschlagkante für den Kolben bildet. Jeder Schlitz 21 hat eine Umfangserstreckung von etwa 1 cm, während der Durchmesser des Kartuschenkörpers 11 ca. 5 cm be­trägt.At the rear end of the cartridge body 11, three inwardly directed projections 20 are arranged, distributed uniformly over the circumference, of which only two are visible in the drawing. Each projection 20 adjoins a slot 21, the region of the wall of the cartridge body 11 arranged behind the slot 21 being pressed inwards and forming the projection 20. The projections 20 have a sawtooth shape in this way, the forward flank 22 constituting the boundary of the slot 21 and forming a stop edge for the piston. Each slot 21 has a circumferential extent of approximately 1 cm, while the diameter of the cartridge body 11 is approximately 5 cm.

Beim Einschieben des Kolbens 14 in den Kartuschenkörper 11 gleiten die schräg nach hinten abstehenden Umfangs­rippen 16 über die Vorsprünge 20, wobei sie vorüber­gehend deformiert werden. Nachdem sämtliche Umfangs­rippen 16 des Kolbens 14 die Vorsprünge 20 passiert haben, ist der Kolben im Inneren des Kartuschenkörpers 11 gefangen. Bei einer Rückwärtsbewegung des Kolbens 14 stößt die hintere Umfangsrippe 16 gegen die Steilflanke 20, so daß eine Blockierung oder Verhakung des Kolbens erfolgt. Der Kolben kann nicht mehr zerstörungsfrei aus dem Kartuschenkörper herausbewegt werden.When the piston 14 is inserted into the cartridge body 11, the circumferential ribs 16 projecting obliquely to the rear slide over the projections 20, whereby they are temporarily deformed. After all the circumferential ribs 16 of the piston 14 have passed the projections 20, the piston is inside the cartridge body 11 caught. When the piston 14 moves backward, the rear circumferential rib 16 abuts the steep flank 20, so that the piston is blocked or caught. The piston can no longer be moved out of the cartridge body without being destroyed.

Die Vorsprünge 20 werden im Anschluß an die Herstellung des Kartuschenkörpers 11 durch Schlitzung und Deformie­rung der Wand des Kartuschenkörpers erzeugt. Nach dem Befüllen des Kartuschenkörpers 11 mit der plastischen Masse braucht lediglich der Kolben 14 eingeschoben zu werden. Montage- oder Verformungsvorgänge sind in diesem Stadium nicht mehr erforderlich.The projections 20 are produced after the manufacture of the cartridge body 11 by slitting and deforming the wall of the cartridge body. After filling the cartridge body 11 with the plastic mass, only the piston 14 needs to be inserted. Assembly or deformation processes are no longer required at this stage.
