Description
Die Erfindung betrifft ein Austragselement für eine Zweikomponentenkartusche.The invention relates to a discharge element for a two-component cartridge.
Zweikomponentenkartuschen, beispielsweise für einen Zweikomponentenkleber, einen Zweikomponentenmörtel oder dergleichen, haben innerhalb einer Kartusche zwei getrennte Aufnahmeräume für jeweils eine Komponente. Üblicherweise sind solche Kartuschen als zylindrische Gehäuse ausgebildet. An einem Stirnende ist ein Hals ausgebildet, aus dessen Stirnseite die beiden Komponenten ausgedrückt werden. Hierzu wird auf den Hals ein Austragselement, üblicherweise auch als Mischer bezeichnet, aufgesetzt. Innerhalb dieses Austragselements ist ein Durchgangskanal mit einer Mischeinrichtung angeordnet, mit dessen Hilfe die beiden Komponenten so miteinander vermischt werden, dass sie aus dem Austrittsende des Mischers als möglichst homogene Mischung ausgedrückt werden.Two-component cartridges, for example for a two-component adhesive, a two-component mortar or the like, have within a cartridge two separate receiving spaces for each one component. Usually, such cartridges are formed as cylindrical housing. At one end of a neck is formed, from the front side of the two components are expressed. For this purpose, a discharge element, usually referred to as a mixer, placed on the neck. Within this discharge element, a passageway with a mixing device is arranged, with the aid of which the two components are mixed together so that they are expressed from the outlet end of the mixer as homogeneous as possible mixture.
Nach Gebrauch ist die Kartusche üblicherweise noch nicht leer. Dann wird das Austragselement abgenommen und das Stirnende des Halses mit einer Verschlusskappe wieder verschlossen, damit der Inhalt nicht austrocknet.After use, the cartridge is usually not empty yet. Then the Austragselement is removed and the front end of the neck closed with a cap, so that the content is not dry out.
Da der Inhalt der Kartusche zähflüssig ist, dringt nach dem Abnehmen des Austragselements noch Material aus den jetzt freiliegenden Öffnungen nach. Vor dem Aufsetzen der Verschlusskappe muss dieses Material entfernt werden. Dies kann mit einem getrennten Werkzeug gemacht werden.Since the contents of the cartridge is viscous, after removal of the discharge element still material from the now exposed openings after. Before attaching the cap, this material must be removed. This can be done with a separate tool.
Bei einer bekannten Zweikomponentenkartusche ist ein Austragselement vorgesehen, das auf den Hals der Zweikomponentenkartusche aufgesetzt werden kann. Zwischen den beiden Ausgangsöffnungen der Kartusche ist ein Steg vorhanden, der ein gleichzeitiges Abstreifen beider Ausgangsöffnungen verhindert (
Ebenfalls bekannt ist ein Austragselement für eine Zweikomponentenkartusche, bei dem seitliche Rippen mit geradlinig verlaufenden Kanten vorhanden sind (
Bei einer weiteren Zweikomponentenkartusche ist ein zu einem gemeinsamen Mischraum führender Aufsatz und getrennt von diesem eine Austragsdüse vorgesehen. Die Austragsdüse kann von dem Aufsatz abgenommen werden (
Eine Düse für eine Einkomponentenkartusche weist Anlageflächen zur Anlage an den Rändern einer Fuge auf (
Ein weiteres Austragselement für eine Einkomponentenkartusche weist seitliche Stabilisierungsflächen auf, mit deren Hilfe eine exakte Ausrichtung der Achse des Austragselements gegenüber einer Wandoberfläche gewährleistet werden soll (
Der Erfindung liegt die Aufgabe zu Grunde, dem Benutzer eine Möglichkeit an die Hand zu geben, das Entfernen von aus den Austragsöffnungen heraus gequollenem Komponentenmaterial zu vereinfachen.The invention is based on the object, the user a way to facilitate the removal of component material swollen from the discharge openings.
Zur Lösung dieser Aufgabe schlägt die Erfindung ein Austragselement mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.To solve this problem, the invention proposes a Austragselement with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
Durch die Anbringung einer solchen Abstreifeinrichtung mit einer Abstreifkante hat der Benutzer nach dem Entfernen des Austragselements von der Kartusche das Werkzeug zum Entfernen der heraus gequollenen Reste gleich zur Hand. Wenn er das Austragselement beispielsweise abgeschraubt hat, hält er es schon in der Hand. Er kann daher ohne Ablegen und Suchen des Werkzeugs die Reinigung sofort durchführen.By attaching such a stripping device with a scraper edge, the user after removing the Austragselements of the cartridge, the tool for removing the swollen out residues right at hand. For example, if he has unscrewed the dispensing element, he already holds it in his hand. He can therefore carry out the cleaning immediately without storing and searching for the tool.
Die Abstreifkante der Abstreifeinrichtung weist eine Form auf, die der Form des Stirnendes des Halses der Zweikomponentenkartusche entspricht. Wenn das Stirnende, in dem die Austrittsöffnungen der Kartusche enden, eben ist, so ist auch die Abstreifkante geradlinig.The wiping edge of the wiper has a shape corresponding to the shape of the front end of the neck of the two-component cartridge. If the front end, in which the outlet openings of the cartridge end, is flat, then the wiping edge is rectilinear.
In Weiterbildung der Erfindung kann vorgesehen sein, dass sich an die Abstreifkante eine Nebenkante anschließt, die quer zur Abstreifkante verläuft und dazu dient, an der radialen Außenseite des Halses der Kartusche anhaftendes Material abzustreifen.In a further development of the invention, provision may be made for a side edge adjoining the wiping edge which runs transversely to the wiping edge and serves to wipe off material adhering to the radially outer side of the neck of the cartridge.
Erfindungsgemäß kann vorgesehen sein, dass die Abstreifeinrichtung mit der Abstreifkante seitlich an dem Austragselement ausgebildet ist, wobei insbesondere vorgesehen sein kann, dass die Abstreifkante parallel oder angenähert parallel zu einer Längsachse des Austragselements verläuft. Die Austragselemente sind in der Regel lang ausgebildet, um einerseits auch an schwierige Stellen herankommen zu können und andererseits eine lange Vermischungsstrecke für die beiden Komponenten vorzusehen. Seitlich ist an einem solchen Austragselement daher ausreichend Platz gegeben, um die Abstreifeinrichtung anzubringen.According to the invention it can be provided that the stripping device is formed with the scraping edge laterally on the discharge element, wherein it can be provided in particular that the stripping edge runs parallel or approximately parallel to a longitudinal axis of the discharge element. The Austragselemente are usually long, on the one hand to get to difficult places and on the other hand to provide a long mixing distance for the two components. The side is therefore given sufficient space on such a discharge element to attach the stripping.
Sinnvoll ist es, was von der Erfindung in Weiterbildung vorgeschlagen wird, dass die Abstreifeinrichtung benachbart zu dem Anschluss für den Hals der Zweikomponentenkartusche ausgebildet ist.It makes sense, what is proposed by the invention in development, that the stripping device is formed adjacent to the connection for the neck of the two-component cartridge.
Es wurde bereits erwähnt, dass die Abstreifeinrichtung eine Nebenkante aufweisen kann, um auch die radiale Außenseite des Halses der Kartusche zu säubern. Erfindungsgemäß kann vorgesehen sein, dass eine an dem Anschluss des Austragselements vorhandene Schulter diese Nebenkante bildet.It has already been mentioned that the stripping device can have a side edge in order to also clean the radial outside of the neck of the cartridge. According to the invention, it can be provided that a shoulder provided on the connection of the discharge element forms this side edge.
In nochmaliger Weiterbildung der Erfindung kann vorgesehen sein, dass die Abstreifkante der Abstreifeinrichtung an einer Rippe des Austragselements ausgebildet ist.In a further development of the invention it can be provided that the wiping edge of the wiper device is formed on a rib of the discharge element.
Bei einer Vielzahl von bekannten Zweikomponentenkartuschen ist eine Austrittsöffnung für eine Komponente zentral angeordnet und weist einen kreisrunden Öffnungsquerschnitt auf. Die Öffnung für die zweite Komponente kann eine diese zentrale Öffnung umgebende Schlitzöffnung sein, oder es können eine oder mehrere Austrittsöffnungen radial außerhalb der zentralen Öffnung vorhanden sein. Erfindungsgemäß ist vorgesehen, dass die Abstreifeinrichtung einen Zapfen für diese zentrale Austrittöffnung aufweist, wobei dann die Abstreifkante sich seitlich an den Zapfen anschließt. Damit wird das Austragselement mit seinem Zapfen in die Zentralöffnung eingesteckt und um diesen Zapfen bzw. die zentrale Öffnung herum verdreht. Dadurch lässt sich das Material der äußeren Öffnungen sehr leicht abstreifen bzw. abschaben. Gleichzeitig dient das Austragselement als Griff. Wegen der großen Länge des Austragselements lässt es sich für diesen von der Erfindung möglich gemachten Zweck günstig handhaben.In a plurality of known two-component cartridges, an outlet opening for a component is arranged centrally and has a circular opening cross-section. The opening for the second component may be a slot opening surrounding this central opening, or one or more exit openings may be present radially outside the central opening. According to the invention it is provided that the stripping device has a pin for this central outlet opening, in which case the stripping edge then adjoins the pin laterally. Thus, the Austragselement is inserted with its pin in the central opening and twisted around this pin or the central opening around. This allows the material of the outer openings very easily strip or scrape. At the same time the discharge element serves as a handle. Because of the large length of the discharge element, it can be handled favorably for this purpose made possible by the invention.
Das Austragselement nach der Erfindung lässt sich sowohl für einen Schraubanschluss als auch für einen Bajonettanschluss einer Zweikomponentenkartusche ausbilden.The Austragselement according to the invention can be both for a Form screw as well as for a bayonet connection of a two-component cartridge.
Der Anschluss kann als Anschlusshülse ausgebildet sein, die auch dazu dienen kann, zum Aufschrauben oder zur Herstellung der Bajonettverbindung an dem Austragselement anzugreifen.The connection can be designed as a connecting sleeve, which can also serve to attack for screwing on or for the production of the bayonet connection to the discharge element.
In nochmaliger Weiterbildung der Erfindung kann vorgesehen sein, dass das Austragselement ein Kunststoffteil ist, insbesondere ein einteiliges Kunststoffteil.In a further development of the invention can be provided that the discharge element is a plastic part, in particular a one-piece plastic part.
Die Erfindung betrifft ebenfalls die Verwendung eines solchen Austragselements zum Abstreifen von Material, das aus den Austragsöffnungen einer Zweikomponentenkartusche herausgequollen ist.The invention also relates to the use of such a discharge element for stripping material that has swelled out of the discharge openings of a two-component cartridge.
Sobald die gewollte Ausgabe von Material beendet ist, wird dabei das Austragselement von der Zweikomponentenkartusche abgenommen und dann die Abstreifkante über die Auslassöffnung der Kartusche bewegt. Damit kann das Material, das über die Ebene der Öffnung vorsteht, abgestreift werden. Anschließend kann die Austragsöffnung mit dem dafür vorgesehenen Deckel verschlossen werden.As soon as the intended dispensing of material has been completed, the dispensing element is removed from the two-component cartridge and then the scraper edge is moved over the outlet opening of the cartridge. Thus, the material that projects beyond the plane of the opening can be stripped off. Subsequently, the discharge opening can be closed with the lid provided for this purpose.
