Abstract

In the dispensing device, preferably a double cartridge (1) having a stopper and a locking ring provided with bayonet connecting means, the stopper (7), the external surfaces of the cartridge outlets (4, 5), and the wall interior of the locking ring (6,) comprise mutually cooperating means (17, 26; 18, 27) for pressing the stopper into the outlets or pulling it out from the outlets as the locking ring is rotated. On one hand, this allows to obtain a tight closure, and on the other hand, it is very simple in this manner to pull out the tightly fitting stopper.

Description

Die vorliegende Erfindung bezieht sich auf eine Austragvorrichtung mit Verschlussstopfen und Verriegelungsring mit Bajonett-Anschlussmitteln gemäss Oberbegriff vom Patentanspruch 1. Solche Austragvorrichtungen, insbesondere Mehrkomponentenkartuschen sind beispielsweise aus der US-A-5 918 772 des gleichen Anmelders bekannt. Bajonett-Anschlussmittel haben, verglichen mit Schraubverschlüssen, den Vorteil, eine Verbindung rasch herstellen oder lösen zu können. Andererseits weisen Bajonett-Anschlussmittel auch Nachteile auf, insbesondere wenn es um grössere Kartuschen geht, wo zum Teil höhere Kräfte erforderlich sind. Dies gilt nicht nur für den Anschluss eines Mischers oder eines Zubehörs sondern insbesondere auch für das Herausziehen des Verschlussstopfens, der infolge der erforderlichen Dichtigkeit leicht konische Zapfen aufweist und daher festsitzt.The present invention relates to a discharge device with sealing plug and locking ring with bayonet connection means according to the preamble of claim 1. Such discharge, in particular multi-component cartridges are for example from the US-A-5,918,772 of the same applicant. Bayonet connection means have the advantage, compared to screw caps, the advantage of being able to establish or release a connection quickly. On the other hand, bayonet connection means also have disadvantages, especially when it comes to larger cartridges, where sometimes higher forces are required. This is true not only for the connection of a mixer or an accessory but in particular for the extraction of the sealing plug, which has slightly conical pin due to the required tightness and therefore stuck.

Aus der US-A-5 137 182 des gleichen Anmelders ist eine Kartusche mit einem Verschlussstopfen gemäß dem Oberbegriff des Anspruchs 1 bekannt, worin die Oberseite der Bajonettnocken keilförmig sein können, um eine bessere Verriegelung zu erzielen.From the US-A-5 137 182 the same applicant, a cartridge with a sealing plug according to the preamble of claim 1 is known, wherein the top of the bayonet cams may be wedge-shaped to achieve a better locking.

Die US-A-5 320 233 offenbart einen Verschluss mit Mitteln, um das Zerreissen eines Sicherheitsbandes anzuzeigen. Das zweiteilige Sicherheitsband weist beidseits einer Schwächungszone Vorsprünge auf, wobei die eine Reihe Vorsprünge auf einer Rampe und die andere Reihe Vorsprünge auf einer anderen Rampe gleiten, wodurch das Band auseinander gerissen wird, falls der Verschluss geöffnet wird.The US-A-5 320 233 discloses a closure with means to indicate the tearing of a security tape. The two-part safety band has projections on either side of a zone of weakness, with one row of projections on one ramp and the other row of projections on another ramp, thereby causing the band to slip is torn apart if the shutter is opened.

Für Kartuschen mit einer Überwurfmutter mit Schraubgewinde zum Befestigen eines Mischers oder eines Stopfens, z. B. gemäss US-A-5 423 443 , ist es bekannt, am Verschlussstopfen eine Abzugscheibe anzubringen, um ihn durch Herausdrehen der Überwurfmutter zu entfernen. Während die Überwurfmutter mit Schraubgewinde einen relativ grossen Hub ermöglicht, um den Verschlussstopfen herauszuheben zu können, kann mit einer herkömmliche Bajonett-Verriegelung keine Abzugkraft ausgeübt werden. Daher konnte dieses Problem bei Bajonett-Anschlussmitteln für grössere Kartuschen mit grösseren Verschlussstopfen bislang nicht gelöst werden.For cartridges with a union nut with screw thread for attaching a mixer or a stopper, z. B. according to US-A-5 423 443 , It is known to attach a trigger disc on the stopper to remove it by unscrewing the nut. While the union nut with screw thread allows a relatively large stroke in order to lift out the stopper, can be exercised with a conventional bayonet locking no pull-off force. Therefore, this problem could not be solved with bayonet connection means for larger cartridges with larger plugs so far.

Es ist davon ausgehend Aufgabe der vorliegenden Erfindung dieses Problem zu lösen und eine Möglichkeit anzugeben, bei einer Bajonett-Verriegelung den Verschlussstopfen durch den Verriegelungsring zu bewegen derart, dass er sich nicht nur zum Verschliessen zur Austragvorrichtung hin bewegt sondern auch von ihr abgehoben werden kann und daher eine Zugkraft ausübt. Diese Aufgabe wird mit den Merkmalen von Patentanspruch 1 gelöst.It is therefore an object of the present invention to solve this problem and to provide a way to move in a bayonet locking the plug through the locking ring such that it not only moves to close to the discharge out but also can be lifted from her and therefore exerts a tensile force. This object is achieved with the features of claim 1.

In den Figuren 1 und 2 erkennt man das Auslassende einer Doppelkartusche 1 mit den beiden Vorratsbehältern 2 und 3, den getrennten Auslässen 4 und 5, dem Verriegelungsring 6 und den Verschlussstopfen 7.In the Figures 1 and 2 one recognizes the outlet end of a double cartridge 1 with the two storage containers 2 and 3, the separate outlets 4 and 5, the locking ring 6 and the sealing plug. 7

Die Erfindung richtet sich vor allem darauf, den Verschlussstopfen 7 durch Drehen des Verriegelungsrings, hier im Gegenuhrzeigersinn, von der Kartusche abzuheben. Der Verschlussstopfen 7 weist zwei Zapfen 8 und 9, einen Anzugflansch 10 und einen daran anschliessenden Hals 11 auf, an dem ein Abzugflansch 12 angebracht ist, der zur Aufnahme einer Abzugscheibe 14 mit Ausnehmung 15 eine Nut 13 aufweist.The invention is primarily directed to the closure plug 7 by turning the locking ring, here counterclockwise, lift off the cartridge. The closure plug 7 has two pins 8 and 9, a tightening flange 10 and a neck 11 adjoining thereto, on which a withdrawal flange 12 is mounted, which has a groove 13 for receiving a take-off disk 14 with a recess 15.

Im Endbereich der beiden Auslässe 4 und 5 befindet sich ein Auslassflansch 16, der an seinem Umfang zwei gegenüberliegende Flanschstege 17 und 18 aufweist. Jeder Flanschsteg besitzt an seiner Unterseite 19 eine Anzugschräge 17A und an ihrer Oberseite 20 eine Abzugschräge 18A, wobei diese Flächen, in axialer Richtung gesehen schräg verlaufen. Die Anzug- und Abzugschrägen 17A und 18A am Auslassflansch der Kartusche kooperieren mit entsprechenden Anzug- und Abzugschrägen im Verriegelungsring.In the end region of the two outlets 4 and 5 there is an outlet flange 16, which has two opposite flange webs 17 and 18 at its periphery. Each flange web has on its underside 19 a suit slope 17A and on its upper side 20 a trigger slope 18A, these surfaces, viewed in the axial direction obliquely. The tightening and haul-off slopes 17A and 18A on the outlet flange of the cartridge cooperate with corresponding tightening and haul-off slopes in the locking ring.

Der Verriegelungsring 6 weist einen geriffelten Drehteil 21 und einen anschliessenden zylindrischen Teil 22 auf, der einen kleineren Innendurchmesser aufweist als der Drehteil, wodurch ein Absatz 23 gebildet wird, der sich auf den Anzugflansch 10 des Stopfens 7 abstützt. Der Durchmesser D1 des Durchlasses 30 an dem den Zapfen abgewandten Ende des zylindrischen Teils 22 ist kleiner als der Durchmesser D2 der Abzugscheibe 14.The locking ring 6 has a corrugated rotary member 21 and a subsequent cylindrical portion 22, which has a smaller inner diameter than the rotary member, whereby a shoulder 23 is formed, which is supported on the tightening flange 10 of the plug 7. The diameter D1 of the passage 30 at the end facing away from the journal of the cylindrical portion 22 is smaller than the diameter D2 of the take-off disk 14th

Im Drehteil des Ringes befinden sich, nahe dem kartuschenseitigen Ende, zwei gegenüberliegende Ringstege 24 und 25, die an ihrer Oberseite mit einer Ringanzugschräge 26 und an ihrer Unterseite mit einer Ringabzugschräge 27 versehen sind. Auch hier verlaufen die Ringanzugschrägen und die Ringabzugschrägen axial gesehen schräg.In the rotating part of the ring are located near the cartridge side end, two opposite annular webs 24 and 25, which are provided on their upper side with a Ringanzugschräge 26 and on its underside with a Ringabzugschräge 27. Again, the ring suit slopes and the Ringabzugsschrägen axially oblique.

In Fig. 3 ist die Arbeitsweise der Vorrichtung in Anzugstellung, bzw. Schliessstellung dargestellt. Dabei kooperieren die Ringstege 24 und 25, die an ihrer Oberseite die Ringanzugschräge 26 und 27 aufweisen, mit je einer unten liegenden Anzugschräge 17A, 18A an Flanschsteg 17, 18 am Auslassflansch 16, um durch Drehen des Verriegelungsrings im Uhrzeigersinn den Verschluss in Pfeilrichtung anzuziehen, bzw. zu verschliessen.In Fig. 3 is the operation of the device in suit position, or closed position shown. In this case, cooperate the annular ribs 24 and 25, which have on their upper side the Ringanzugschräge 26 and 27, each with an underlying suit slope 17A, 18A to flange web 17, 18 at the outlet 16 to rotate by turning the locking ring in Clockwise to tighten the closure in the direction of arrow, or to close.

In Fig. 4, die die Abzugsbewegung in Pfeilrichtung zeigt, kooperieren die unten liegenden Abzugschrägen 26, 27 derselben Ringstege 24, 25 des Verriegelungsringes 6 mit den obenliegenden Abzugschrägen 17A, 18A an Flanschstege 17, 18 am Auslassflansch 16, um den Verschlussstopfen mittels des Verriegelungsrings zu lösen und abzuheben. Dabei greift die ringförmige Stirnseite 28 am Verriegelungsring an der Abzugscheibe 14 an.In Fig. 4 showing the withdrawal movement in the direction of the arrow, cooperate the underlying Abzugsschrägen 26, 27 of the same annular webs 24, 25 of the locking ring 6 with the overhead Abzugsschrägen 17A, 18A on flange webs 17, 18 at the Auslassflansch 16 to release the closure plug by means of the locking ring and lift , In this case, the annular end face 28 engages the locking ring 14 on the locking ring.

Im Drehteil des Verriegelungsringes sind ferner beim Übergang zu Absatz 23, zwischen den Stegen 24 und 25, Zentrierrippen 29 angeordnet, die in axialer Richtung schräg vom Drehteil zum zylindrischen Teil verlaufen, um ein Zentrieren des Verriegelungsringes zu ermöglichen, siehe Figuren 5 und 6.In the rotary part of the locking ring centering ribs 29 are further arranged at the transition to paragraph 23, between the webs 24 and 25, which extend in the axial direction obliquely from the rotary member to the cylindrical part to allow a centering of the locking ring, see FIGS. 5 and 6 ,

In Fig. 5 ist in einem Schnitt der Verschlussstopfen mitsamt dem Verriegelungsring in verriegelter Stellung und in Fig. 6 in entriegelter Stellung dargestellt. Aus den Zeichnungen geht ferner hervor, dass sich beim Verriegeln der Absatz 23 am Verriegelungsring auf dem Anzugflansch 10 des Stopfens aufstützt, während die beiden Anzugsschrägen miteinander kooperieren, um die Zapfen des Verschlussstopfen in die Kartusche zu pressen und dass beim Entriegeln die ringförmige Stirnseite 28 des zylindrischen Teils des Verschlusstopfens die Abzugsscheibe 14 in einer Nut im Verschlussstopfen beaufschlagt wird, während die beiden Abzugsschrägen beim Herausdrehen miteinander kooperieren, um den Verschlussstopfen herauszuziehen.In Fig. 5 is in a section of the sealing plug together with the locking ring in the locked position and in Fig. 6 shown in unlocked position. From the drawings also shows that when locking the shoulder 23 is supported on the locking ring on the tightening flange 10 of the plug, while the two Anzugsschrägen cooperate with each other to press the pins of the stopper into the cartridge and that upon unlocking the annular end face 28 of cylindrical portion of the Verschlußstopfens the pulley 14 is acted upon in a groove in the sealing plug, while the two Abzugsschrägen cooperate when unscrewing with each other to pull out the sealing plug.

Zum Verschliessen der Kartuschenauslässe wird zuerst der im Verriegelungsring vormontierte Verschlussstopfen in die Auslässe der Kartusche gedrückt und durch Drehen des Ringes um 90° verriegelt. Zum Entriegeln wird der Verriegelungsring um etwas mehr als 90° zurück gedreht, wodurch der Verschlussstopfen herausgezogen wird und zusammen mit dem Verriegelungsring entfernt werden kann. Nachher kann nach Herausnahme der Abzugscheibe der Verschlussstopfen aus dem Verriegelungsring entfernt und mit demselben Verriegelungsring ein Mischer an der Kartusche befestigt werden.To close the cartridge outlets, first push the locking plug pre-mounted in the locking ring into the outlets of the cartridge and lock it by turning the ring by 90 °. To unlock the locking ring is rotated back by slightly more than 90 °, whereby the plug is pulled out and can be removed together with the locking ring. Subsequently, after removing the trigger disk, the sealing plug can be removed from the locking ring and a mixer can be fastened to the cartridge with the same locking ring.

In der Ausführungsvariante gemäss den Figuren 7 und 8 wird an Stelle der Abzugscheibe die Längserstreckung von Abzugflansch 31 in Bezug auf den Abzugflansch 12 auf eine Länge D2 vergrössert, die grösser ist als der Durchmesser D1 der Öffnung 32 des Verriegelungsringes 33. Damit die ringförmige Stirnseite 34 des Verriegelungsringes unter den Abzugflansch gelangen kann, weist die Öffnung 32 an zwei gegenüberliegenden Seiten je eine Ausnehmung 35 auf, so dass der Abzugflansch 31 hindurchgelangen kann.In the embodiment according to the FIGS. 7 and 8 In the place of the take-off disk, the longitudinal extent of the discharge flange 31 with respect to the take-off flange 12 is increased to a length D2 which is greater than the diameter D1 of the opening 32 of the locking ring 33. Thus, the annular end face 34 of the locking ring can pass under the take-off flange the opening 32 on two opposite sides each have a recess 35, so that the trigger flange 31 can pass therethrough.

Zur Verstärkung der Abzugsbewegung des Verschlussstopfens 35 weist die Unterseite vom Abzugflansch zwei gegenüberliegende Abzugflanschschrägen 36 und 37 auf.To reinforce the withdrawal movement of the sealing plug 35, the underside of the trigger flange on two opposite Abzugflanschschrägen 36 and 37.

Die übrigen Teile sowie die Wirkungsweise ist dieselbe wie bei der ersten Ausführung mit Abzugscheibe. Der Verschlussstopfen wird aufgesetzt, der Verriegelungsring derart auf den Abzugflansch gesetzt, dass dieser beim Verriegeln durch die Öffnung 32 hindurchgelangt. Zum Entriegeln wird der Verriegelungsring zunächst gedreht um den Verschlussstopfen frei zu geben und in einer weiteren Drehbewegung wird der Verschlussstopfen herausgehoben. Diese Lösung hat den Vorteil, ein an sich verlierbares Teil - Abzugscheibe - weniger zu enthalten.The remaining parts as well as the mode of action is the same as in the first version with trigger pulley. The stopper is placed, the locking ring set on the trigger flange so that it passes through the opening 32 during locking. To unlock the locking ring is first rotated to give the stopper free and in another Rotary movement of the plug is lifted out. This solution has the advantage of containing a per se loseable part - take-off disc - less.

Die oben beschriebene Lösung mit Abzugflanschschrägen ist auch auf eine Ausführung mit einem Verriegelungsring mit einem Schraubgewinde übertragbar, wobei das Schraubgewinde mit einem Gewinde am Auslassflansch der Austragvorrichtung zusammenwirkt.The abovementioned flanged-flange approach is also applicable to an embodiment having a screw threaded locking ring, the screw thread cooperating with a thread on the outlet flange of the dispensing device.

Ausgehend von dem gezeigten Ausführungsbeispiel sind viele Variationen denkbar, ohne den Bereich der Erfindung zu verlassen. So können die Auslassöffnungen und/oder die Zapfen konisch sein, die Auslassöffnungen und damit auch die Zapfen können von der zylindrischen Form abweichen, beispielsweise D-förmig sein, die bajonettartige Verriegelung und entsprechend die Entriegelung kann im Uhrzeigersinn oder gegen den Uhrzeigersinn erfolgen, sowohl die Vorratsbehälter als auch die Auslässe können voneinander verschieden sein und beispielsweise eine Querschnittsfläche, bzw. ein Volumen in einem Verhältnis von 1 : 1 bis 1 : 10 aufweisen und die Zapfen des Verschlussstopfens können sowohl im Durchmesser als auch in der Länge unterschiedlich sein. Anstelle der Abzugscheibe kann auch ein Spreizstift oder ein Schnappring oder dergl. verwendet werden.Starting from the illustrated embodiment, many variations are conceivable without departing from the scope of the invention. Thus, the outlet openings and / or the pins may be conical, the outlet openings and thus the pins may deviate from the cylindrical shape, for example, be D-shaped, the bayonet-type locking and accordingly the unlocking can be done in a clockwise or counterclockwise direction, both Reservoir and the outlets may be different from each other and, for example, a cross-sectional area, or a volume in a ratio of 1: 1 to 1: 10 and the pins of the sealing plug may be different both in diameter and in length. Instead of the pulley, a spreader pin or a snap ring or the like. Can be used.

Aus der Beschreibung der Erfindung geht hervor, dass unter Beibehalt der Vorteile einer Bajonett-Verbindung eine gute Dichtung und eine problemlose Lagerung durch den eingepressten Verschluss gewährleistet, eine einfache, sichere und saubere Bedienung sowie eine leichte und schnelle Montage und Demontage des Verschlusses möglich ist.From the description of the invention shows that while maintaining the advantages of a bayonet connection ensures a good seal and easy storage by the pressed closure, a simple, safe and clean operation and easy and quick assembly and disassembly of the closure is possible.

Das beschriebene Ausführungsbeispiel bezieht sich zwar auf eine Doppelkartusche, doch kann der Verschliess- und Abhebemechanismus auch für andere Austragvorrichtungen oder Kartuschen verwendet werden, beispielsweise für Einkomponentenkartuschen sowie Mehrkomponentenkartuschen oder -Austragvorrichtungen.While the described embodiment relates to a dual cartridge, the capping and lifting mechanism may also be used for other dispensers or cartridges, for example, single component cartridges and multi-component cartridges or dispensers.
