Abstract

The invention relates to a cartridge system comprising a tubular cartridge pistol and a cartridge which can be inserted into the cartridge pistol. The outlet end of the cartridge protrudes out of the cartridge pistol when the cartridge is in an inserted position. The cartridge is provided with an attachment piece at the end for attaching an outlet nozzle. The aim of the invention is to improve the cartridge system in such a way that handling during operation of the system is considerably simplified and in particular no additional auxiliary elements are required apart from said cartridge system. To this end, the attachment piece is sealed with a pierceable membrane on the inside, and the outlet nozzle is provided with piercing elements at the attachment end for piercing the membrane. The piercing elements can be engaged with the attachment pierce.

Description

Die Erfindung betrifft ein Kartuschensystem mit einer rohrförmigen Kartuschenpistole und einer in die Kartuschenpistole einsetzbaren Kartusche, welche mit ihrem Austrittsende in eingeführter Lage aus der Kartuschenpistole herausragt, wobei die Kartusche an ihrem Austrittsende mit einem Befestigungsstutzen zum Befestigen einer Austrittsdüse versehen ist.The invention relates to a cartridge system with a tubular Cartridge gun and one that can be inserted into the cartridge gun Cartridge, which with its outlet end in the inserted position from the Cartridge gun protrudes, with the cartridge at its exit end Equipped with a mounting socket for attaching an outlet nozzle is.

Bekannte Kartuschensysteme dieser Art weisen eine rohrförmige Kartuschenpistole auf, welche am Austrittsende eine Durchstecköffnung für das Austrittsende der Kartusche aufweist. Diese Kartusche weist am Austrittsende einen Befestigungsstutzen auf, welcher endseitig verschlossen ist und ein Außengewinde trägt. Vor dem Gebrauch einer solchen, vorzugsweise aus Kunststoff bestehenden Kartusche, ist es erforderlich, das kappenförmige Ende des Befestigungsstutzens mit einem Messer abzuschneiden, um anschließend auf die so geöffnete Kartusche eine Austrittsdüse aufzuschrauben und die so ausgerüstete Kartusche dann in die Kartuschenpistole einzusetzen.Known cartridge systems of this type have a tubular one Cartridge gun, which has a push-through opening at the outlet end has the outlet end of the cartridge. This cartridge points to Exit end on a fastening piece, which is closed at the end and has an external thread. Before using one, preferably plastic cartridge, it is necessary that cut off the cap-shaped end of the fastening piece with a knife, to then place one on the opened cartridge Unscrew the outlet nozzle and then insert the cartridge equipped in this way insert the cartridge gun.

Ein solches Kartuschensystem ist ersichtlich relativ aufwendig zu bedienen, da zum Öffnen der Kartusche ein Messer oder dergl. benötigt wird, welches häufig nicht greifbar zur Verfügung steht. Außerdem ist von weiterem Nachteil, daß das abgeschnittene kappenförmige Ende entsorgt werden muß oder dieses unkontrolliert auf den Boden fällt, was insbesondere dann unerwünscht ist, wenn, was nicht auszuschließen ist, dieser abgeschnittene kappenförmige Bereich mit dem Kartuscheninhalt verschmutzt ist. Ist eine solche Kartusche beispielsweise mit Klebstoff oder einer Fugendichtmasse gefüllt, kann dies unerwünschte Folgen nach sich ziehen, wenn dadurch beispielsweise Klebstoffreste am Fußboden anhaften.Such a cartridge system is evidently relatively difficult to use because a knife or the like is required to open the cartridge, which is often required is not available. Another disadvantage is that the clipped cap-shaped end must be disposed of or this falls to the ground in an uncontrolled manner, which is particularly undesirable if what cannot be ruled out is this cut off cap-shaped area the contents of the cartridge are dirty. Is such a cartridge, for example filled with adhesive or a joint sealant, this can have undesirable consequences if there is, for example, adhesive residue on the floor adhere.

Weiterhin ist ein in dem amerikanischen Patent US-A-4 453 651 beschriebenes Kartuschensystem bekannt, bei dem eine einstückige Austrittsdüse an ihrem Befestigungsende sechs hervorstehende Zähne aufweist, mit welchen eine Membran durchstoßen wird, bevor die Kartusche in die Kartuschenpistole eingesetzt wird. Danach dreht der Benutzer eine Düse, damit die von den sechs Zähnen durchstoßene Membran vollständig von einem Befestigungsstutzen abgetrennt wird. Die Austrittsdüse wird dann wieder von der Kartusche zurückgezogen und die an der Düse anhaftenden Membranreste werden manuell entfernt. Danach wird die Düse wieder am Befestigungsstutzen angebracht.Furthermore, there is one described in U.S. Patent 4,453,651 Cartridge system known in which a one-piece outlet nozzle on her Fastening end has six protruding teeth, with which one Membrane is pierced before the cartridge into the cartridge gun is used. The user then turns a nozzle so that the one of the six Membrane punctured completely by an attachment piece is separated. The outlet nozzle is then removed from the cartridge withdrawn and the membrane residues adhering to the nozzle are manually away. Then the nozzle is attached to the mounting piece again.

Aus dem Dokument der US-A-4 461 454 ist ein Kartuschensystem bekannt, bei dem im gebrauchsfertigen Zustand eine Austrittsdüse aus drei in Längsrichtung ineinander verschiebbaren Teilen besteht. Zwar kann auch hier durch Verschieben eines "Düsenoberteils" in Richtung auf die Kartusche eine Membran durchstoßen werden, aber es sind keine Rastmittel vorgesehen, die ein unbeabsichtigtes Durchstoßen der Membran noch vor dem Einsetzen der Kartusche in die Kartuschenpistole verhindern. Ein Ventil am Ende der Austrittsdüse verhindert unkontrolliertes Austreten der Masse.A cartridge system is known from US-A-4,461,454 in the ready-to-use state, an outlet nozzle from three in the longitudinal direction there are mutually movable parts. Although can also pass through here Moving a "nozzle upper part" towards the cartridge a membrane be pierced, but there are no locking means provided that a unintentional puncture of the membrane before inserting the Prevent cartridge in the cartridge gun. A valve at the end of the Outlet nozzle prevents the mass from escaping in an uncontrolled manner.

Aufgabe der Erfindung ist es deshalb, eine wie im Anspruch 1 vorgeschlagene, verbesserte Vorrichtung bereitzustellen.The object of the invention is therefore to provide a provide improved device.

Zur Lösung dieser Aufgabe wird erfindungsgemäß ein Kartuschensystem mit den Merkmalen des Anspruchs 1 vorgeschlagen.To achieve this object, a cartridge system with the Features of claim 1 proposed.

Durch diese Gestaltung ist es nicht mehr erforderlich, zum Öffnen der Kartusche ein Messer oder dergl. zu verwenden, die Kartusche ist innenseitig im Befes tigungsstutzen durch die Membran verschlossen und kann auf einfache Weise quasi selbsttätig durch die Montage der Austrittsdüse am Befestigungsstutzen geöffnet werden. Die so geöffnete und ausgerüstete Kartusche kann dann anschliessend in normaler Weise in die Kartuschenpistole eingesetzt werden. Ersichtlich ergibt sich beim Öffnen der Kartusche somit kein Abfall, der zu Boden fallen könnte bzw. sonst entsorgt werden müßte.With this design, it is no longer necessary to open the cartridge to use a knife or the like, the cartridge is inside the fastening Closing connection sealed by the membrane and can be easily quasi automatically by mounting the outlet nozzle on the mounting piece be opened. The cartridge opened and equipped in this way can then be used can be inserted into the cartridge gun in the normal way. apparent there is no waste falling to the floor when the cartridge is opened could or should otherwise be disposed of.

Vorzugsweise ist vorgesehen, daß die Membran innerhalb der Kartusche am Fuße des Befestigungsstutzens angeordnet ist. Dadurch wird vermieden, daß eine Beschädigung der Membran ungewollt bzw. versehentlich erfolgt, bevor die Kartusche eingesetzt wird, weil die Membran selbst geschützt angeordnet ist. Ggf. kann zusätzlich auch noch vorgesehen sein, daß auf den Befestigungsstutzen eine Schutzkappe aufgesetzt ist. Diese Kappe kann dann, da die Membran den Kartuscheninhalt von der Kappe trennt, jedoch nicht verschmutzt werden.It is preferably provided that the membrane on the inside of the cartridge Base of the mounting bracket is arranged. This avoids that damage to the membrane occurs unintentionally or accidentally before the Cartridge is used because the membrane itself is protected. Possibly. can also be provided that the A protective cap is attached to the fastening socket. This cap can then since the membrane separates the cartridge contents from the cap, but not become dirty.

Alternativ kann auch vorgesehen sein, daß die Membran im Bereich des Austritts des Befestigungsstutzens angeordnet ist.
Besonders vorteilhaft ist vorgesehen, daß die Austrittsdüse aus einem am Befestigungsstutzen befestigbaren Düsenunterteil und einem in Längsrichtung begrenzt innerhalb des Düsenunterteiles verschiebbaren, am inneren Ende die Durchstechmittel aufweisenden Düsenoberteil besteht. Das Düsenunterteil kann dann zunächst bei noch geschlossener Kartusche auf den Befestigungsstutzen der Kartusche aufgesetzt bzw. aufgeschraubt werden und durch Längsverschiebung des Düsenoberteiles in das Düsenunterteil hinein wird dann automatisch die Membran der Kartusche durchstochen und somit die Öffnung der Kartusche freigegeben. Die Verschiebung des Düsenoberteiles kann vorteilhaft erst dann erfolgen, wenn die Kartusche schon in die Kartuschenpistole eingesetzt ist.Alternatively, it can also be provided that the membrane is arranged in the region of the outlet of the fastening socket.
It is particularly advantageously provided that the outlet nozzle consists of a lower part of the nozzle which can be fastened to the fastening socket and a upper part of the nozzle which can be displaced longitudinally within the lower part of the nozzle and which has the piercing means at the inner end. When the cartridge is still closed, the lower nozzle part can then first be placed or screwed onto the mounting socket of the cartridge and the longitudinal displacement of the upper nozzle part into the lower nozzle part then automatically pierces the membrane of the cartridge and thus opens the opening of the cartridge. The upper part of the nozzle can advantageously only be moved when the cartridge has already been inserted into the cartridge gun.

Um die Handhabung einer solchen zweigeteilten Austrittsdüse zum Öffnen der Kartusche weiter zu vereinfachen, ist besonders vorteilhaft vorgesehen, daß das Düsenoberteil und das Düsenunterteil beabstandet voneinander jeweils erste und zweite korrespondierende Rastmittel aufweisen, wobei das Düsenoberteil entgegen der Wirkung der ersten Rastmittel in Längsrichtung bis in die Rastposition der zweiten Rastmittel verschiebbar ist. Durch diese Ausgestaltung ist sichergestellt, daß sich die beiden Düsenteile zunächst in der ersten Rastposition befinden, in welcher die Durchstechmittel des Düsenoberteiles nicht nach unten aus dem Düsenunterteil herausstehen, und daß erst nach dem Aufsetzen bzw. Aufschrauben des Düsenunterteiles am Befestigungsstutzen der Kartusche das Düsenoberteil aus der ersten Rastposition in die zweite Rastposition verschoben wird, in weicher die Durchstechmittel die Membran der Kartusche durchstechen. To handle such a two-part outlet nozzle for opening the To further simplify the cartridge, it is particularly advantageously provided that the The upper nozzle part and the lower nozzle part are spaced from each other first and have second corresponding latching means, the nozzle upper part against the action of the first locking means in the longitudinal direction up to the Locking position of the second locking means is displaceable. Through this configuration it is ensured that the two nozzle parts are first in the first Rest position are in which the piercing means of the upper part of the nozzle is not protrude downward from the lower part of the nozzle, and that only after Attaching or screwing on the lower part of the nozzle on the attachment socket of the Cartridge the nozzle upper part from the first locking position into the second locking position is moved into which the piercing means the membrane of the Pierce the cartridge.

Um die Verschiebung des Düsenoberteiles in das Düsenunterteil hinein weiter zu vereinfachen ist vorgesehen, daß das Düsenoberteil außenseitig einen umlaufenden Anschlag aufweist. Dieser Anschlag kann als Handhabungsgriff dienen.To further shift the upper part of the nozzle into the lower part of the nozzle simplify it is provided that the upper part of the nozzle on the outside revolving stop. This stop can be used as a handle serve.

Eine ganz besonders bevorzugte Ausführungsform der Erfindung zeichnet sich dadurch aus, daß die Kartuschenpistole ein topfförmig ausgebildetes Austrittsende aufweist, welches das Düsenunterteil und das Düsenoberteil bereichsweise umgibt und eine Durchtrittsöffnung für das Düsenoberteil aufweist, deren Größe derart ist, daß das Düsenoberteil in eingeführter Lage mit seinem Anschlag in Anlage an den Rand der Austrittsöffnung kommt. Durch diese Ausgestaltung wird die Handhabung des Kartuschensystemes noch wesentlich weiter vereinfacht. Es wird zunächst das Düsenunterteil mit dem darin befindlichen Düsenoberteil auf die Kartusche aufgeschraubt, anschließend wird die so ausgerüstete Kartusche in die Kartuschenpistole eingesetzt, wobei während des Einsetzens der Anschlag des Düsenoberteiles in Anlage an den Rand der Austrittsöffnung des topfförmig ausgebildeten Austrittsendes der Kartuschenpistole kommt, wodurch dann durch weiteres Einschieben der Kartusche in die Kartuschenpistole bzw. Betätigen des Abzugshebels, der die Kolbenstange und somit die Kartusche nach vorne schiebt, zwangsweise aufgrund der Anlage des Anschlages am Rand der Austrittsöffnung des topfförmigen Austrittsendes der Kartuschenpistole das Düsenoberteil von der ersten Rastposition in die zweite Rastposition in das Düsenunterteil hineingeschoben wird, wodurch das Öffnen der Membran bzw. das Durchstechen derselben erfolgt.A very particularly preferred embodiment of the invention is distinguished characterized in that the cartridge gun is a cup-shaped Exit end, which has the lower nozzle part and the upper nozzle part surrounds in areas and has a passage opening for the upper part of the nozzle, whose size is such that the upper part of the nozzle in its inserted position Stop comes into contact with the edge of the outlet opening. Through this configuration the handling of the cartridge system is still essential further simplified. First the lower part of the nozzle with the one in it screwed nozzle top part onto the cartridge, then the cartridge equipped in this way is inserted into the cartridge gun, whereby while inserting the stop of the nozzle upper part in contact with the Edge of the outlet opening of the cup-shaped outlet end of the cartridge gun comes, which then by pushing the cartridge in the cartridge gun or actuating the trigger that holds the piston rod and thus pushes the cartridge forward, due to the system of the stop at the edge of the outlet opening of the cup-shaped outlet end the cartridge pistol the upper part of the nozzle from the first stop position to the second locking position is pushed into the lower part of the nozzle, whereby the The membrane is opened or pierced.

Dabei kann, beispielsweise zur Nachrüstung von normalen Kartuschenpistolen, weiterhin vorgesehen sein, daß das topfförmige Austrittsende als Einzelteil ausgebildet ist, welches in die Kartuschenpistole einsetzbar ist.Here, for example for retrofitting normal cartridge guns, further be provided that the cup-shaped outlet end as a single part is formed, which can be inserted into the cartridge gun.

Besonders vorteilhaft kann weiterhin vorgesehen sein, daß in das Düsenoberteil ein Absperrhahn integriert ist. Mit einem solchen Absperrhahn kann verhindert werden, daß nach der Applikation noch Masse aus der Düse austreten kann. Außerdem kann durch Einstellen der Durchtrittsöffnungsgröße des Absperrhahns der Volumenstrom zusätzlich zum Druckaufbau am Pistolengriff der Kartuschenpistole variiert werden.It can also be particularly advantageously provided that in the upper part of the nozzle a shut-off valve is integrated. With such a stopcock can be prevented be that after the application mass can still emerge from the nozzle. In addition, by adjusting the opening size of the stopcock the volume flow in addition to the pressure build-up on the pistol grip Cartridge gun can be varied.

Oberhalb des Absperrhahns kann sich entweder ein Gewinde am Düsenoberteil befinden, auf das eine normale, marktgängige Düse aufgeschraubt werden kann, oder der Absperrhahn kann direkt in die Düsenspitze münden.Above the shut-off valve, there can either be a thread on the upper part of the nozzle on which a normal, commercially available nozzle can be screwed, or the shut-off valve can flow directly into the tip of the nozzle.

Von einem erfindungsgemäßen Kartuschensystem ist in Figur 1 eine rohrförmige Kartuschenpistole mit 1 bezeichnet und nur bereichsweise dargestellt. In diese Kartuschenpistole 1 ist in die stirnseitige Austrittsöffnung ein topfförmig ausgebildetes Austrittsende 2 eingesetzt, welches stimendseitig eine Durchtrittsöffnung 3 aufweist.A cartridge system of a cartridge system according to the invention is shown in FIG Cartridge gun designated 1 and shown only in areas. In these Cartridge gun 1 is a pot-shaped in the front exit opening trained exit end 2 is used, which on the stimulus side Passage opening 3 has.

Das Kartuschensystem weist darüber hinaus eine rohrförmige, beispielsweise aus Kunststoff bestehende, Kartusche 4 auf, welche an ihrem Austrittsende mit einem Befestigungsstutzen 5 mit Außengewinde 6 versehen ist. Die Kartusche 4 ist im Bereich des Befestigungsstutzens 5 innenseitig mit einer Membran 7 verschlossen. Die Membran kann alternativ auch im Bereich des Austritts des Befestigungsstutzens 5 angeordnet sein. Diese Position der Membran ist in Figur 1 gestrichelt angedeutet und mit dem Bezugszeichen 7' bezeichnet.The cartridge system also has a tubular, for example Plastic existing cartridge 4, which at its outlet end with a Fastening nozzle 5 is provided with an external thread 6. The cartridge 4 is in the Area of the fastening piece 5 on the inside with a membrane 7 locked. The membrane can alternatively also in the area of the outlet of the Fastening socket 5 may be arranged. This position of the membrane is in figure 1 indicated by dashed lines and designated by reference numeral 7 '.

Auf den Befestigungsstutzen 5 der Kartusche 4 ist eine Austrittsdüse 8 aufschraubbar, welche beim Ausführungsbeispiel nach Figur 1 aus zwei Teilen besteht, nämlich einem Düsenunterteil 9 und einem Düsenoberteil 10. Das Düsenoberteil 10 ist dabei begrenzt in Längsrichtung innerhalb des Düsenunterteiles 9 verschiebbar angeordnet. Die Verschiebung wird dabei durch Rastmittel begrenzt, nämlich erste Rastmittel und zweite Rastmittel. Die ersten Rastmittel sind dabei von einer umlaufenden Rastwulst 11 am Außenumfang des Düsenoberteiles 10 und einer korrespondierenden Rastnut 12 am Düsenunterteil 9 gebildet, während die zweiten Rastmittel von der Rastwulst 11 und einer zweiten, weiter innen liegenden Rastnut 13 im Düsenunterteil 9 gebildet sind.An outlet nozzle 8 is located on the attachment piece 5 of the cartridge 4 screwable, which in the embodiment of Figure 1 consists of two parts consists, namely a lower nozzle part 9 and an upper nozzle part 10. Das Upper nozzle part 10 is limited in the longitudinal direction within the Lower nozzle part 9 slidably arranged. The shift is thereby Limited locking means, namely first locking means and second locking means. The first Locking means are of a circumferential locking bead 11 on the outer circumference of the Upper nozzle part 10 and a corresponding locking groove 12 on the lower nozzle part 9 formed, while the second locking means of the locking bead 11 and one second, further inner locking groove 13 are formed in the lower nozzle part 9.

Das Düsenoberteil 10 weist darüber hinaus außerhalb des in das Düsenunterteil 9 eingesteckten Bereiches einen umlaufenden Anschlag 14 auf. Außerdem ist am inneren Ende des Düsenoberteiles 10 ein spitz zulaufendes dornenförmiges Ende 15 ausgebildet, welches geeignet ist, bei entsprechender Positionierung die Membran 7 der Kartusche 4 zu durchstechen. Die geometrischen Abmessungen des Düsenoberteiles 10 sind so gewählt, daß dann, wenn sich die Rastwulst 11 in der ersten Rastnut 12 des Düsenunterteiles 9 befindet, die Durchstechmittel 15 in aufgeschraubter Lage des mit einem Innengewinde 16 ausgerüsteten Düsenunterteiles 9 nicht so weit in den Befestigungsstutzen 5 eintreten können, daß sie in Kontakt mit der Membran 7 geraten können. Wird das Düsenoberteil 10 entgegen der Rastwirkung der ersten Rastmittel 11, 12 in das Düsenunterteil 9 hineingeschoben, bis die Rastwulst 11 in der zweiten Rastnut 13 einrastet, so ist der Abstand des Anschlages 14 so gewählt, daß der Anschlag 14 diese Verschiebebewegung nicht behindert, sondern in dieser Lage etwa am freien Ende des Düsenunterteiles 9 anliegt. Gleichzeitig sind die Durchstechmittel 15 so angeordnet, daß in dieser Lage die Durchstechmittel 15 die Membran 7 durchdringen, d.h. öffnen.
Die Handhabung des Kartuschensystemes erfolgt derart, daß zunächst die Düse 8 in der in der Zeichnung dargestellten Position von Düsenunterteil 9 und Düsenoberteil 10 auf die Kartusche 4 bzw. die Befestigungsstutzen 5 der Kartusche 4 aufgeschraubt wird. Die so ausgerüstete Kartusche 4 wird anschließend in die Kartuschenpistole eingeführt, derart, daß der Anschlag 14 am Rand der Durchtrittsöffnung 3 des topfförmigen Austrittsendes 2 der Kartuschenpistole 1 anliegt. Die Kartusche 4 wird nun weiter in die Kartuschenpistole 1 eingeschoben, derart, daß aufgrund der Anlage des Anschlages 14 das Düsenoberteil 10 in das Düsenunterteil 9 hineingeschoben wird. Dabei wird die Kartusche 4 beim Betätigen der Pistole 1 nach vorne gedrückt, so daß die Rastwulst 11 in der zweiten Rastnut 13 einrastet. Bei diesem Vorgang wird die Membran 7 von den Durchstechmitteln 15 durchstochen und die Kartusche 4 ist geöffnet, so daß anschließend das Kartuschensystem einsatzbereit ist.The upper nozzle part 10 also has a circumferential stop 14 outside the area inserted into the lower nozzle part 9. In addition, a pointed, thorn-shaped end 15 is formed on the inner end of the nozzle upper part 10, which end is suitable for piercing the membrane 7 of the cartridge 4 with appropriate positioning. The geometric dimensions of the upper nozzle part 10 are chosen so that when the locking bead 11 is in the first locking groove 12 of the lower nozzle part 9, the piercing means 15 in the screwed-on position of the lower nozzle part 9, which is provided with an internal thread 16, do not enter the fastening socket 5 as far that they can come into contact with the membrane 7. If the upper nozzle part 10 is pushed into the lower nozzle part 9 against the latching action of the first latching means 11, 12 until the latching bead 11 engages in the second latching groove 13, the distance of the stop 14 is selected such that the stop 14 does not hinder this displacement movement, but rather in this position lies approximately at the free end of the lower nozzle part 9. At the same time, the piercing means 15 are arranged such that in this position the piercing means 15 penetrate the membrane 7, ie open it.
The cartridge system is handled in such a way that first the nozzle 8 is screwed onto the cartridge 4 or the attachment piece 5 of the cartridge 4 in the position of the lower nozzle part 9 and upper nozzle part 10 shown in the drawing. The cartridge 4 equipped in this way is then inserted into the cartridge gun in such a way that the stop 14 bears against the edge of the passage opening 3 of the cup-shaped outlet end 2 of the cartridge gun 1. The cartridge 4 is now pushed further into the cartridge gun 1 such that, due to the abutment of the stop 14, the upper nozzle part 10 is pushed into the lower nozzle part 9. The cartridge 4 is pressed forward when the gun 1 is actuated, so that the locking bead 11 engages in the second locking groove 13. In this process, the membrane 7 is pierced by the piercing means 15 and the cartridge 4 is opened so that the cartridge system is then ready for use.

In Figur 2 ist eine weitere Ausführungsform eines erfindungsgemäßen Kartuschensystems dargestellt, das weitgehend der Ausführungsform nach Figur 1 entspricht. Es sind deshalb dieselben Bezugszeichen wie in Figur 1 verwandt, sofern gleiche Teile betroffen sind. Im Unterschied zur Ausführungsform nach Figur 1 ist bei der Ausführungsform nach Figur 3 in das Düsenoberteil 10 ein Absperrhahn 17 und Handhabungsgriff 18 integriert. Durch Schließen dieses Absperrhahnes 17 ist es möglich, das Kartuschensystem nach der Applikation zu verschließen, so daß keine Masse mehr aus der Düse austreten kann. Dieser geschlossene Zustand ist in Figur 2 dargestellt. Außerdem kann durch Einstellen der Öffnungsgröße des Absperrhahnes 17, was durch den Doppelpfeil in Figur 2 angedeutet ist, der Volumenstrom zusätzlich zum Druckaufbau am Pistolengriff variiert werden. Oberhalb des Absperrhahnes 17 geht das Düsenoberteil 10 in die Düsenspitze über.In Figure 2 is another embodiment of an inventive Cartridge system shown that largely corresponds to the embodiment according to FIG. 1. Therefore, they are the same Reference numerals as used in Figure 1, provided the same parts are affected. in the The difference to the embodiment according to FIG. 1 is in the embodiment according to 3 shows a shut-off valve 17 and handle 18 in the upper part 10 of the nozzle integrated. By closing this stopcock 17, it is possible Seal the cartridge system after application so that there is no more mass can emerge from the nozzle. This closed state is shown in Figure 2. In addition, by adjusting the opening size of the stopcock 17, what is indicated by the double arrow in Figure 2, the volume flow in addition to Pressure build-up on the pistol grip can be varied. Above the stopcock 17 goes the upper nozzle part 10 into the nozzle tip.

In Figur 3 ist eine weitere Ausführungsform dargestellt, die der Ausführungsform nach Figur 2 weitgehend entspricht. Der einzige Unterschied der Ausführungsform nach Figur 3 gegenüber derjenigen nach Figur 2 besteht darin, daß das Düsenoberteil 10 oberhalb des Absperrhahnes 17 in ein Außengewinde 19 mündet, auf das ein nicht dargestelltes marktgängiges Düsenendstück aufschraubbar ist. Das Düsenoberteil 10 weist bei dieser Ausführungsform über seiner gesamten Länge im wesentlichen den gleichen Durchtrittsquerschnitt auf, was durch die Durchmesserangabe a angedeutet ist. FIG. 3 shows a further embodiment, that of the embodiment largely corresponds to Figure 2. The only difference of the embodiment 3 compared to that of Figure 2 is that the Upper nozzle part 10 opens into an external thread 19 above the shut-off valve 17, onto which a commercially available nozzle end piece, not shown, can be screwed. The In this embodiment, the upper nozzle part 10 has a length over its entire length essentially the same cross section on what is due to the Diameter specification a is indicated.

Natürlich ist die Erfindung nicht auf die dargestellten Ausführungsbeispiele beschränkt. Weitere Ausgestaltungen sind möglich, ohne den Grundgedanken zu verlassen. So kann bei der Ausführungsform nach Figur 1 die Kartuschenpistole 1 auch einteilig mit dem topfförmigen Austrittsende 2 ausgebildet sein und dergl. mehr.Of course, the invention is not limited to the illustrated embodiments limited. Further configurations are possible without the basic idea leave. Thus, in the embodiment according to FIG. 1, the cartridge pistol can 1 can also be formed in one piece with the cup-shaped outlet end 2 and the like. more.
