Definitions
- the present invention relates to a one-part or multi-part stopper on a discharge cartridge according to the preamble of claim 1.
- Discharge cartridges are used for the targeted and metered application of adhesives, sealants and other highly viscous compounds in many areas. Examples include industry, construction and dental technology.
- multi-chamber mostly two-chamber cartridges for two-component compounds.
- the chambers of these cartridges, and of course the single-chamber cartridges, must be tightly sealed before use.
- plug-in plugs are common, which are manufactured separately from the cartridges, are inserted into the outlet opening of the cartridge before filling and are secured by means of a union nut.
- the first possibility suffers from the fact that this special tool is not always at hand and that it needs a separate tool for each cartridge type.
- the second option makes the stopper more expensive and also increases the storage volume of the cartridge, since the extension must be made quite stable and large in order to be easy to grasp manually.
- a stopper according to the preamble of claim 1 is known from EP-A-0 431 347, with the securing means being unlocked and removed in all versions for pulling out the stopper the stopper is then pulled out, whereby the disadvantages described above also come into play here.
- An object of the present invention is to provide a stopper that can be removed from a discharge cartridge without tools.
- the plug is inserted into the discharge opening of the cartridge and, if necessary, pressed in and locked by means of a screw ring or the like.
- the stopper has an extension projecting beyond the screw ring.
- a trigger is now attached laterally over the end of the screw ring and grasping the extension.
- This trigger means is designed in such a way that the screw ring can be rotated relative to the stopper since it has to be unscrewed from the discharge opening again in order to replace the stopper against the discharge nozzle. When unscrewing, however, a pulling force is transferred to the stopper thanks to the pulling means and the stopper is thus pulled out.
- the plug 1 shows the plug 1 with the screw ring 3 surrounding it.
- the screw ring 3 has an inner bevel 5 against which the shoulder 7 of the plug 1 lies and which can press it into the discharge opening of the cartridge.
- the extension of the plug 1 is designed here as a pull plate 12 which projects beyond the screw ring 3 and is connected to the body of the plug 1 via a neck 13.
- the trigger means 15 is designed as a slotted disc.
- the slot 16 can receive the neck 13 and the disc 15 is slightly thinner than the neck 13 is long.
- the disk 15 can be pushed according to the arrow 17 over the upper edge of the screw ring 3 under the tension plate 12, which results in the state according to FIG. 4.
- the screw ring 3 is simply unscrewed, the stopper 1 also being pulled off. It is important that the disc 15 can slide easily enough under the pressure forces during the removal either on the upper edge of the screw ring 3 and / or can twist relative to the plug 1.
- a generally U-shaped trigger can be used, the legs of which grip the extension on the stopper between them.
- the base of the U and also the leg ends are advantageously made flat, so that the screw ring can be turned underneath.
- the rotatability around the plug extension can also be sufficient.
- the leg ends, as well as the slot ends of the disk 15, can be funnel-shaped will.
- the pulling means can advantageously spread out at the inserted end and / or have barb elements in order to prevent falling out. It is also possible to carry out one leg while a second leg encompasses the neck.
- an elongated trigger means made of a resilient material in the manner of a clip 19, as shown by way of example in FIG. 6. If it is in principle U-shaped, it can be pushed laterally over the neck 13, after which the legs encompass the neck of the extension. An expansion adapted to the neck can preferably be provided in the legs, as a result of which the trigger means snaps onto the neck 13 of the extension. It is also possible to use a shape closed on both sides, roughly corresponding to an elongated oval, and advantageously to provide the extension with a tapered end. The trigger is then placed on the extension from above, the tapered end expanding the trigger against the spring force by the wedge effect, and the trigger then snaps into the taper. Here, too, a preferably central widening of the legs can be provided in order to prevent undesired lateral displacement.
- another part securing the stopper on the discharge opening 9 may also be present, e.g. B. one with a bayonet catch.
- this part since this part is designed for manual operation, simply pulling on it is sufficient to exert the force required to pull out the plug. In these cases, only a limited rotatability of the trigger means relative to the securing part or the stopper has to be guaranteed if the securing means is caused by a rotary movement must be unlocked, which makes the solution with pens etc. applicable in particular.
- the cartridges can also only be delivered with the plug inserted, i.e. H. without the screw ring 3. This is usually available at the place of use, e.g. B. if it is used to attach the mixing attachment or the discharge nozzle to the cartridge.
- the specified round parts can also be other, e.g. B. rectangular or polygonal outlines show how particularly the disc 15 and the tension plate 12.
- the neck 13 can be changed up to a web extending over the entire width of the tension plate 12. It is also possible to provide in the neck 13 fastening elements, such as depressions or elevations, which correspond to corresponding complementary designs on the trigger means 13 and secure it against falling off.
- the cartridge consists of separately manufactured and optionally separately filled individual bodies, the outlet openings of which can be combined with the partial plugs therein to form one of the embodiments or modifications presented.
- section line 20 shows a possible division of the stopper into two. The bracket 19 and the rod 18 as well as the screw ring 3 are each in one piece. The two part plugs are then pulled out together.
Description
Die vorliegende Erfindung bezieht sich auf einen ein- oder mehrteiligen Stopfen an einer Austragkartusche gemäss Oberbegriff von Anspruch 1.The present invention relates to a one-part or multi-part stopper on a discharge cartridge according to the preamble of
Austragkartuschen werden zum gezielten und dosierten Applizieren von Klebstoffen, Dichtstoffen und anderen hochviskosen Massen in vielen Bereichen angewandt. Als Beispiele seien Industrie, Baugewerbe und Dentaltechnik genannt. Neben Einkammerkartuschen gibt es auch mehrkammerige, überwiegend zweikammerige Kartuschen für Zweikomponentenmassen. Die Kammern dieser Kartuschen, und natürlich auch die Einkammerkartuschen, müssen bis zur Verwendung dicht verschlossen sein. Dazu sind Einsteckstopfen gängig, die getrennt von den Kartuschen hergestellt werden, vor dem Füllen in die Auslassöffnung der Kartusche eingesteckt und mittels einer Überwurfmutter gesichert werden.Discharge cartridges are used for the targeted and metered application of adhesives, sealants and other highly viscous compounds in many areas. Examples include industry, construction and dental technology. In addition to single-chamber cartridges, there are also multi-chamber, mostly two-chamber cartridges for two-component compounds. The chambers of these cartridges, and of course the single-chamber cartridges, must be tightly sealed before use. For this purpose, plug-in plugs are common, which are manufactured separately from the cartridges, are inserted into the outlet opening of the cartridge before filling and are secured by means of a union nut.
Da die Dichtwirkung des Stopfens nur durch die Pressung des Stopfens in der Auslassöffnung bewirkt wird, sind relativ grosse Kräfte für die Entfernung des Stopfens nötig. Dazu sind bisher entweder Werkzeuge üblich, oder der Stopfen muss einen entsprechend stabilen, gut greifbaren Fortsatz aufweisen.Since the sealing effect of the stopper is only achieved by pressing the stopper in the outlet opening, relatively large forces are required to remove the stopper. So far, either tools have been customary for this, or the stopper must have a correspondingly stable, easily graspable extension.
Die erste Möglichkeit krankt daran, dass dieses spezielle Werkzeug nicht immer zur Hand ist, und es für jeden Kartuschentyp ein eigenes Werkzeug braucht. Die zweite Möglichkeit verteuert den Stopfen und vergrössert auch das Staumass der Kartusche, da der Fortsatz recht stabil und gross ausgeführt sein muss, um gut manuell greifbar zu sein.The first possibility suffers from the fact that this special tool is not always at hand and that it needs a separate tool for each cartridge type. The second option makes the stopper more expensive and also increases the storage volume of the cartridge, since the extension must be made quite stable and large in order to be easy to grasp manually.
Ein Stopfen gemäss Oberbegriff von Anspruch 1 ist aus der EP-A-0 431 347 bekannt, wobei in allen Ausführungen zum Herausziehen des Stopfens das Sicherungsmittel entsichert und der Stopfen dann herausgezogen wird, wobei auch hier die oben beschriebenen Nachteile zum Tragen kommen.A stopper according to the preamble of
Eine Aufgabe der vorliegenden Erfindung besteht darin, einen Stopfen anzugeben, der ohne Werkzeug von einer Austragkartusche abgezogen werden kann.An object of the present invention is to provide a stopper that can be removed from a discharge cartridge without tools.
Ein solcher Stopfen ist im Anspruch 1 angegeben, die weiteren Ansprüche beinhalten bevorzugte Ausführungen.Such a stopper is specified in
Demgemäss wird der Stopfen in die Austragöffnung der Kartusche eingesetzt und gegebenenfalls mittels eines Schraubrings o. ä. eingepresst und verriegelt. Der Stopfen weist einen über den Schraubring hinausragenden Fortsatz auf. Es wird nun seitlich über das Ende des Schraubrings hinweg und den Fortsatz erfassend ein Abzugsmittel angebracht. Dieses Abzugsmittel ist derart gestaltet, dass der Schraubring gegenüber dem Stopfen verdreht werden kann, da er zum Auswechseln des Stopfens gegen die Austragdüse von der Austragöffnung wieder abgeschraubt werden muss. Beim Abschrauben wird jedoch dank des Abzugsmittels eine Zugkraft auf den Stopfen übertragen und dieser damit herausgezogen.Accordingly, the plug is inserted into the discharge opening of the cartridge and, if necessary, pressed in and locked by means of a screw ring or the like. The stopper has an extension projecting beyond the screw ring. A trigger is now attached laterally over the end of the screw ring and grasping the extension. This trigger means is designed in such a way that the screw ring can be rotated relative to the stopper since it has to be unscrewed from the discharge opening again in order to replace the stopper against the discharge nozzle. When unscrewing, however, a pulling force is transferred to the stopper thanks to the pulling means and the stopper is thus pulled out.

Fig. 1 zeigt den Einsteckstopfen 1 mit dem ihn umfassenden Schraubring 3. Der Schraubring 3 weist eine innere Schräge 5 auf, an die sich die Schulter 7 des Einsteckstopfens 1 anlegt und die ihn in die Austragöffnung der Kartusche hineindrücken kann. Der Fortsatz des Einsteckstopfen 1 ist hier als Zugplatte 12 ausgeführt, die über den Schraubring 3 hinausragt und über einen Hals 13 mit dem Körper des Einsteckstopfen 1 verbunden ist.1 shows the
Das Abzugsmittel 15 ist als geschlitzte Scheibe ausgebildet. Der Schlitz 16 kann den Hals 13 aufnehmen, und die Scheibe 15 ist etwas dünner als der Hals 13 lang ist. Wie Fig. 3 zeigt, kann die Scheibe 15 gemäss dem Pfeil 17 über den oberen Rand des Schraubrings 3 hinweg unter die Zugplatte 12 geschoben werden, wonach sich der Zustand gemäss Fig. 4 ergibt.The trigger means 15 is designed as a slotted disc. The
Soll nun die verschlossene Kartusche geöffnet werden, so wird einfach der Schraubring 3 abgeschraubt, wobei der Stopfen 1 mit abgezogen wird. Wichtig ist dabei, dass die Scheibe 15 leicht genug auch unter den Andruckkräften während des Abziehens entweder auf der Oberkante des Schraubring 3 gleiten kann und/oder sich gegenüber dem Einsteckstopfen 1 verdrehen kann.If the closed cartridge is now to be opened, the
Abwandlungen sind im Rahmen der Erfindung vorstellbar. Anstelle einer Scheibe kann ein allgemein U-förmiges Abzugsmittel verwendet werden, dessen Schenkel den Fortsatz am Stopfen zwischen sich erfassen. Vorteilhaft sind die Basis des U und auch die Schenkelenden flächig ausgeführt, damit der Schraubring darunter gedreht werden kann. Es kann jedoch auch die Drehbarkeit um den Stopfenfortsatz ausreichen. Zur Erleichterung des Aufsteckens auf den Fortsatz, insbesondere den Hals 13, können die Schenkelenden, wie auch die Schlitzenden der Scheibe 15, trichterförmig ausgebildet werden. Möglich ist es auch, den Fortsatz mit einer Durchbrechung, Bohrung o. ä. auszustatten, durch den das Abzugsmittel in der Art eines Bolzens, Stifts oder Splints 18 durchgesteckt werden kann (Fig. 5). Vorteilhaft kann sich das Abzugsmittel am durchgesteckten Ende spreizen und/oder Widerhakenelemente aufweisen, um ein Herausfallen zu verhindern. Auch eine Durchführung eines Schenkels, während ein zweiter Schenkel den Hals umfasst, ist möglich.Modifications are conceivable within the scope of the invention. Instead of a disk, a generally U-shaped trigger can be used, the legs of which grip the extension on the stopper between them. The base of the U and also the leg ends are advantageously made flat, so that the screw ring can be turned underneath. However, the rotatability around the plug extension can also be sufficient. To facilitate plugging onto the extension, in particular the
Eine weitere Möglichkeit besteht darin, ein längliches Abzugsmittel aus einem federnden Material in der Art einer Klammer 19 vorzusehen, wie es beispielhaft Figur 6 zeigt. Falls es prinzipiell U-förmig ausgebildet ist, kann es seitlich über den Hals 13 geschoben werden, wonach die Schenkel den Hals des Fortsatzes umfassen. Vorzugsweise kann in den Schenkeln eine dem Hals angepasste Aufweitung vorgesehen sein, wodurch das Abzugsmittel am Hals 13 des Fortsatzes einschnappt. Es ist auch möglich, eine beidseitig geschlossene Form zu verwenden, in etwa einem langezogenen Oval entsprechend, und den Fortsatz vorteilhaft mit einem verjüngt auslaufenden Ende auszustatten. Das Abzugsmittel wird dann von oben auf den Fortsatz gesteckt, wobei das verjüngte Ende das Abzugsmittel gegen die Federkraft durch die Keilwirkung aufweitet, und das Abzugsmittel dann in der Verjüngung einschnappt. Auch hier kann eine vorzugsweise mittige Aufweitung der Schenkel vorgesehen sein, um eine ungewollte seitliche Verschiebung zu verhindern.Another possibility is to provide an elongated trigger means made of a resilient material in the manner of a
Anstelle eines Schraubrings kann auch ein anderweitig den Stopfen auf der Austragöffnung 9 sicherndes Teil vorhanden sein, z. B. eines mit Bajonettverschluss. Da dieses Teil jedenfalls für die Handbedienung ausgelegt ist, kann einfach das Ziehen an diesem genügen, um die zum Herausziehen des Stopfens nötige Kraft aufzubringen. In diesen Fällen muss nur noch eine begrenzte Drehbarkeit des Abzugsmittels gegenüber dem sichernden Teil oder dem Stopfen gewährleistet sein, wenn das Sicherungsmittel durch eine Drehbewegung entriegelt werden muss, was insbesondere die Lösung mit Stiften usw. anwendbar macht.Instead of a screw ring, another part securing the stopper on the
Die Kartuschen können auch nur mit eingestecktem Stopfen ausgeliefert werden, d. h. ohne den Schraubring 3. Dieser ist am Einsatzort in der Regel vorhanden, z. B. wenn er zur Befestigung des Mischvorsatzes oder der Austragdüse an der Kartusche dient.The cartridges can also only be delivered with the plug inserted, i.e. H. without the
Die angegebenen runden Teile können auch andere, z. B. rechteckige oder mehreckige Umrisse zeigen, wie besonders die Scheibe 15 und die Zugplatte 12. Auch der Hals 13 kann bis zu einem über die ganze Breite der Zugplatte 12 reichenden Steg verändert werden. Es ist auch möglich, in dem Hals 13 Befestigungselemente, wie Vertiefungen oder Erhebungen vorzusehen, die mit entsprechenden komplementären Ausbildungen am Abzugsmittel 13 korrespondieren und dieses gegen Abfallen sichern.The specified round parts can also be other, e.g. B. rectangular or polygonal outlines show how particularly the
Es ist auch vorstellbar, dass die Kartusche aus getrennt hergestellten und gegebenenfalls separat gefüllten Einzelkörpern besteht, deren Auslassöffnungen sich mit den darin befindlichen Teilstopfen zu einer der vorgestellten Ausführungsformen oder Abwandlungen davon vereinigen lassen. In den Figuren 5 und 6 zeigt die Schnittlinie 20 eine mögliche Zweiteilung des Stopfens. Die Klammer 19 und der Stab 18 wie auch der Schraubring 3 sind dabei jeweils einteilig. Die beiden Teilstopfen werden dann gemeinsam herausgezogen.It is also conceivable that the cartridge consists of separately manufactured and optionally separately filled individual bodies, the outlet openings of which can be combined with the partial plugs therein to form one of the embodiments or modifications presented. In FIGS. 5 and 6,
