Description

Kartuschen für plastische Massen wie beispielsweise Dichtstoffe, Fugenfiillstoffe, Klebstoffe und dergleichen in Gestalt zähflüssiger plastischer Massen bestehen aus einem hinten offenen und vorne durch eine Stirnwand verschlossenen Rohrkörper, und an der vorderen Stirnwand ist ein Mundstück angeformt.Cartridges for plastic materials such as sealants, joint fillers, adhesives and the like in the form of viscous plastic masses consist of a rear open tubular body, closed at the front by a front wall, and at the front A mouthpiece is formed on the end wall.

Üblicherweise ist das Mundstück, das mit einem Außengewinde zum Aufschrauben einer Düse versehen ist, vorne mit einer geschlossenen Spitze ausgebildet, die zum Gebrauch der Kartusche abgeschnitten wird. Die so angebrochene Kartusche ist dann nicht mehr verschließbar.Usually the mouthpiece is with an external thread for screwing on Nozzle is provided with a closed tip at the front, which is used for the Cartridge is cut off. The opened cartridge can then no longer be closed.

Bei Zweikomponentenkartuschen ist es üblich, ein Mundstück mit zwei Auslässen vorzusehen, die bei Nichtgebrauch durch einen Deckel, üblicherweise einen mit einer Schraubhülse zu sichernden Doppelstopfen, verschließbar sind. Zum Gebrauch wird der Deckel abgenommen und statt dessen eine Mischdüse aufgesetzt.With two-component cartridges, it is common to provide a mouthpiece with two outlets, that when not in use through a lid, usually one with a screw sleeve double plugs to be secured are closable. The lid is used removed and put a mixing nozzle instead.

Aus dem DE Gbm 202 06 461 ist eine verschließbare Austragsdüse bekannt, die auf ein herkömmliches Kartuschenmundstück, das vor Ingebrauchnahme aufzuschneiden ist, aufgeschraubt werden kann. Diese Düse enthält eine kegelige Spitze, die eine seitliche Austrittsöffnung aufweist, und eine diese umschließende äußere Düsenhülse mit ebenfalls kegeliger, vorne offener Spitze und einem hinteren Griffteil, das auf ein Außengewinde des Düsenkörpers aufgeschraubt ist. Eine Drehbewegung der äußeren Düsenhülse wird durch das Schraubgewinde in eine Axialbewegung umgesetzt, welche den kegeligen vorderen Teil der äußeren Düsenhülse axial von der kegeligen Düsenspitze abhebt oder mit dieser in Anlage bringt, um die seitliche Austrittsöffnung der Düsenkegelspitze zu öffnen oder zu verschließen. Diese bekannte Anordnung erfordert nach wie vor das Aufschneiden des Kartuschenmundstücks und das anschließende Aufschrauben der Düse, und darüber hinaus hat die bekannte Anordnung den Nachteil, daß zwischen der Düse und der äußeren Düsenhülse ein sich von der Austrittsöffnung nach hinten bis zum Schraubgewinde erstreckender Spalt und damit ein Totraum vorhanden ist, in dem sich unkontrolliert Kartuscheninhaltsmasse ansammeln und Störungen verursachen kann.A closable discharge nozzle is known from DE Gbm 202 06 461, which acts on a Conventional cartridge mouthpiece, which has to be cut open before use can be. This nozzle contains a tapered tip that has a side exit opening and an outer nozzle sleeve enclosing this, also with a conical, open tip at the front and a rear handle that fits onto an external thread of the Nozzle body is screwed on. The outer nozzle sleeve is rotated by the screw thread is converted into an axial movement which corresponds to the conical front Part of the outer nozzle sleeve axially lifts off from or with the conical nozzle tip System brings to open or close the lateral outlet opening of the nozzle cone tip close. This known arrangement still requires the cutting of the Cartridge mouthpiece and the subsequent screwing of the nozzle, and beyond the known arrangement has the disadvantage that between the nozzle and the outer nozzle sleeve one extending from the outlet opening backwards to the screw thread Gap and thus a dead space is present, in which the cartridge content is uncontrolled can accumulate and cause interference.

    In den Zeichnungen (Figuren 1 bis 15) ist jeweils eine Kartusche 1 mit einem Verschluss 2 mit Öffnungs-/Schließ-Funktion dargestellt. Die Schnittdarstellungen zeigen jeweils den oberen Endteil des Kartuschenkörpers mit Kartuschenrohrwand 11 und vorderer Stirnwand 12 sowie dem an der vorderen Stirnwand angeformten Mundstück 13.In the drawings (FIGS. 1 to 15) there is a cartridge 1 with a closure 2 shown with opening / closing function. The sectional views each show the upper end part of the cartridge body with cartridge tube wall 11 and front end wall 12 and the mouthpiece 13 formed on the front end wall.

    Allen Ausführungsformen ist gemeinsam, daß das Mundstück 13 an seinem vorderen Ende eine geschlossene Querplatte 14 aufweist, die über eine kranzartige Anordnung axialer Stege 15 mit dem übrigen Mundstück 13 verbunden ist, so dass zwischen dem Mündungsende der geschlossenen Mantelwand des Mundstücks 13 und der Querplatte 14 ein Kranz seitlicher Austrittsöffnungen zwischen den einzelnen Stegen 14 gebildet ist.All embodiments have in common that the mouthpiece 13 at its front end has a closed cross plate 14 which is axially arranged over a ring-like arrangement Web 15 is connected to the rest of the mouthpiece 13, so that between the mouth end the closed jacket wall of the mouthpiece 13 and the cross plate 14 a wreath lateral outlet openings between the individual webs 14 is formed.

    Der Kartuschenverschluss 2 mit Öffnungs-/Schließ-Funktion besteht jeweils aus dem einstückig mit dem übrigen Kartuschenkörper 1 ausgebildeten feststehenden Mundstück 13 mit dessen eben beschriebenen Teilen sowie einem auf dieses aufgesetzten Verschlussteil 3 in Gestalt einer beweglichen Hülse. Bei den Ausführungsformen nach den Figuren 1 bis 5 (Schiebeausführung) und nach den Figuren 6 bis 10 (Schraubausführung) hat das Verschlussteil 3 an seinem oberen Ende jeweils einen offenen Hals 31 mit Außengewinde zum Aufschrauben einer Düse (nicht dargestellt). Bei der Ausführungsform nach den Figuren 11 bis 15 ist eine Düse 32 bereits einstückig mit dem Verschlussteil 3 ausgebildet.The cartridge closure 2 with opening / closing function consists of the Fixed mouthpiece 13 formed integrally with the rest of the cartridge body 1 with the parts just described and a closure part 3 placed thereon in the form of a movable sleeve. In the embodiments according to FIGS. 1 to 5 (Sliding version) and according to Figures 6 to 10 (screw version) has the closure part 3 at its upper end each an open neck 31 with an external thread Screwing on a nozzle (not shown). In the embodiment according to the figures 11 to 15, a nozzle 32 is already formed in one piece with the closure part 3.

    Bei allen Ausführungsformen weist das Verschlussteil einen rückwärtigen erweiterten Hülsenteil 33 auf, der die axial bewegliche Verbindung des Verschlussteils 3 mit dem Mundstück 13 herstellt, und einen vorderen verengten Halsteil (bei der Ausführungsform nach den Figuren 11 bis 15 ist das die Düse 32) auf, dessen rückwärtiger Innenwandbereich am Übergang zum hinteren Hülsenteil 33 als schwach konische Dichtfläche 34 ausgebildet ist, die im geschlossenen Zustand des Kartuschenverschlusses mit in der hinteren Position befindlichem Verschlussteil 3 (Figuren 4 und 5 bzw. Figuren 9 und 10 bzw. Figuren 14 und 15) dichtend mit dem Umfangsrand bzw. der vorzugsweise ebenfalls konischen Umfangskantenfläche der Querscheibe 14 zusammenwirkt. Dadurch ergibt sich eine saubere, absolut dicht schließende Dichtung.In all embodiments, the closure part has a rear, expanded sleeve part 33 on the axially movable connection of the closure part 3 with the mouthpiece 13, and a front neck portion (in the embodiment of FIG 11 to 15, this is the nozzle 32), the rear inner wall area of which on Transition to the rear sleeve part 33 is designed as a weakly conical sealing surface 34, the one in the closed state of the cartridge closure with the one in the rear position Closure part 3 (Figures 4 and 5 or Figures 9 and 10 or Figures 14 and 15) sealing with the peripheral edge or the preferably also conical peripheral edge surface the cross disk 14 cooperates. This results in a clean, absolutely tight-fitting seal.

    In der Offenstellung (Figuren 2 und 3 bzw. Figuren 7 und 8 bzw. Figuren 12 und 13) befindet sich das Verschlussteil 3 in seiner axial etwas auswärts auf dem Mundstück 13 verschobenen Position, so dass Masse aus der Kartusche durch die seitlichen Austrittsöffnungen am vorderen Ende des Mundstücks in den hinteren erweiterten Innenraum des Verschlussteils 3 und axial an der Querscheibe 14 vorbei in den Hals 31 bzw. die Düse 32 gelangen kann.In the open position (Figures 2 and 3 or Figures 7 and 8 or Figures 12 and 13) the closure part 3 moved axially somewhat outward on the mouthpiece 13 Position so that mass from the cartridge through the side outlet openings at the front end of the mouthpiece in the rear expanded interior of the closure part 3 and axially past the cross disk 14 into the neck 31 or the nozzle 32 can.

    Bei der Schiebeausführung (Figuren 1 bis 5) hintergreift ein rückwärtiger Innenwulst 35 des Hülsenteils 33 einen äußeren Ringwulst 16 am vorderen Ringwandende des Mundstücks 13. Der Ringswulst 16 des Mundstücks 13 wirkt dichtend mit einer zylindrischen Innenfläche des Hülsenteils 33 zusammen. Die Verhältnisse sind so gewählt, daß sich eine ausreichend große Reibung ergibt, daß das Verschlussteil in jeder Stellung hinreichend fest sitzt, also insbesondere in geschlossener Stellung sich nicht ungewollt verschiebt. Dabei kann die Schließstellung durch eine leichte Raste am rückwärtigen Ende des Schiebewegs (nicht dargestellt) definiert bzw. gesichert werden.In the sliding version (FIGS. 1 to 5), a rear inner bead 35 engages behind of the sleeve part 33 an outer annular bead 16 at the front end of the ring wall of the mouthpiece 13. The annular bead 16 of the mouthpiece 13 acts sealingly with a cylindrical Inner surface of the sleeve part 33 together. The conditions are chosen so that one Sufficiently large friction means that the closure part is sufficiently firm in every position sits, so in particular in the closed position does not move unintentionally. there can the closed position by a slight detent at the rear end of the sliding path (not shown) can be defined or saved.

    Bei der Schraubausführung (Figuren 6 bis 10) wirken das hintere Ende des Hülsenteils 33 und das Mundstück 13 über komplementäre Gewindeelemente 17, 36 derart zusammen, daß eine Drehbewegung des Verschlussteils 3 über die Gewindeverbindung in eine Axialverschiebung umgesetzt wird. Auch bei der Schraubausführung ist am vorderen Ende der geschlossenen Ringwand des Mundstücks 13 ein Außenwulst 16 vorhanden, der dichtend mit der zylindrischen Innenwand des Hülsenteils 33 zusammenwirkt. Dies gilt gleichermaßen für die insoweit übereinstimmende Ausführungsform nach den Figuren 11 bis 15.In the screw version (FIGS. 6 to 10), the rear end of the sleeve part 33 acts and the mouthpiece 13 together via complementary threaded elements 17, 36, that a rotational movement of the closure part 3 via the threaded connection in an axial displacement is implemented. The screw version also has the closed ring wall of the mouthpiece 13, an outer bead 16 is present, the sealing cooperates with the cylindrical inner wall of the sleeve part 33. This applies equally for the corresponding embodiment according to FIGS. 11 to 15.

    Das Zusammenwirken des Außenwulsts 16 des Mundstücks 13 mit einem zylindrischen Innenwandbereich des Hülsenteils 33 verhindert, daß irgendwelches Material der Kartuschenfüllmasse nach rückwärts in den Spalt zwischen Hülsenteil 33 und Mundstück 13 austreten und diesen verunreinigen kann. The interaction of the outer bead 16 of the mouthpiece 13 with a cylindrical Inner wall area of the sleeve part 33 prevents any material of the cartridge filling compound backwards into the gap between sleeve part 33 and mouthpiece 13 can leak and contaminate it.

    Bei den Ausführungsformen nach den Figuren 6 bis 10 und 11 bis 15 mit Schraubfunktion kann in der Schließposition, also am rückwärtigen Ende der Drehbewegung des Verschlussteils, eine Rastung durch komplementäre Elemente 18 bzw. 37 von Mundstück 13 und Hülsenteil 33 vorgesehen sein, was auch den Vorteil hat, daß den Benutzer das Erreichen der Schließposition fühlbar signalisiert wird.In the embodiments according to FIGS. 6 to 10 and 11 to 15 with screw function can in the closed position, i.e. at the rear end of the rotary movement of the closure part, a catch by complementary elements 18 and 37 of mouthpiece 13 and sleeve part 33 can be provided, which also has the advantage that the user can reach the closing position is clearly felt.
