Abstract

An elastic inner tube (1) is contained inside an outer tube (2) which has a finger-pressure opening (3). One end of the silicon rubber inner tube tapers to an applicator tip (5), whilst the other end is closed to the ambient atmosphere. The applicator tip is slit like a fountain pen or is in the form of a brush, and closed by a cap (7). The interior has a ventilation valve (6).

Description

Bei der Herstellung von künstlichen Zähnen oder dgl. wird nach wie vor die Keramikmasse in Form eines Schlickers mit dem Pinsel per Hand auf das Objekt aufgetragen. Diese Technik unterscheidet sich fast in nichts von der Technik eines Malers, der von einer Farbpalette mit dem Pinsel Ölfarbe auf ein Bild aufträgt, nur daß der Zahntechniker normalerweise eine Glasplatte benutzt.In the manufacture of artificial teeth or the like Ceramic mass in the form of a slip with the brush on the object by hand applied. This technique differs almost nothing from the technique of one Painter who only applies oil paint to a picture from a palette with a brush that the dental technician normally uses a glass plate.

Da Schlicker aus einer Mischung aus Keramikpulver und üblicherweise Wasser besteht, verdunstet das Wasser aus der Mischung heraus, wodurch der Schlicker unbrauchbar, da zu zäh, wird. Insbesondere bei Alumina-Schlickern ist das Was­ serverhältnis eine sehr kritische Größe. Bei nicht-optimalem Wasserverhältnis ergibt sich beim Brennen ein schlechtes Gefüge und damit eine geringe Bruchfestigkeit. Da dies dem Zahntechniker bekannt ist, bringt er an den auf der Arbeitsglasplatte befindlichen Schlicker Feuchtigkeitsspeicher an, z. B. feuchte Papierkügelchen usw. Der Phantasie sind in diesem Punkt keine Grenzen gesetzt.Because slurry consists of a mixture of ceramic powder and usually water , the water evaporates from the mixture, causing the slip unusable because it becomes too tough. The thing is especially with alumina slips server ratio a very critical size. If the water ratio is not optimal there is a bad structure during firing and thus a small one Breaking strength. Since this is known to the dental technician, he brings to the on the Working glass plate located slurry moisture storage, z. B. damp Paper balls etc. There are no limits to the imagination in this point.

Anderseits besteht aber auch die Gefahr, daß durch das erforderliche Pinsel­ auswaschen zuviel Wasser in den Schlicker eingetragen wird. Auch dies hat im Endeffekt die gleichen negativen Folgen.On the other hand, there is also the risk that the required brush wash out too much water is entered into the slip. This also has in Ultimately, the same negative consequences.

Es ist daher Aufgabe der in Anspruch 1 angegebenen Erfindung ein Auftraggerät für Keramikmassen anzugeben, das ein konstantes Flüssigkeit/Keramikpulver- Verhältnis beim Arbeiten garantiert.It is therefore an object of the invention specified in claim 1, an applicator to indicate for ceramic masses that a constant liquid / ceramic powder Relationship guaranteed when working.

Vorteilhafte Weiterbildungen sind in den Unteransprüchen 2 bis 6 beschrieben. Das Innenrohr gemäß Anspruch 7 gewährleistet die optimale Schlicker­ anmischung bereits beim Keramikhersteller.Advantageous further developments are described in subclaims 2 to 6. The inner tube according to claim 7 ensures the optimal slip Mixing already at the ceramic manufacturer.

Fig. 1 einen Schnitt durch die Auftragvorrichtung in einem vergrößerten Maßstab; Figure 1 is a section through the coating apparatus on an enlarged scale.

Fig. 2 eine Draufsicht auf die Auftragvorrichtung in Richtung des Pfeiles a der Fig. 1. Fig. 2 is a plan view of the applicator in the direction of the arrow a in FIG. 1.

Die Auftragvorrichtung besteht aus einem Außenrohr 2, das bei Gebrauch wie ein Pinsel in der Hand des Zahntechnikers liegt. In das Außenrohr 2 ist ein elastisches Innenrohr, vorzugsweise aus Silikonkautschuk, eingelegt, das mit der Keramik­ masse 4 gefüllt ist. Außenrohr 2 und Innenrohr 1 verjüngen sich zu einer Auftrag­ spitze 5. Da der Innenraum der Auftragvorrichtung durch eine Kappe 7 verschlos­ sen ist, kann durch Ausübung eines Fingerdruckes über die Fingerdrucköffnung 3 ein Überdruck erzielt werden, der den Schlicker an der Auftragspitze 5 austreten läßt. Um einen Unterdruck abbauen zu können, der beim Zurückgehen des einge­ drückten Innenrohres 1 in die Normallage entsteht, ist ein Belüftungsventil 6 vor­ gesehen.The application device consists of an outer tube 2 which, when in use, lies in the hand of the dental technician like a brush. In the outer tube 2 , an elastic inner tube, preferably made of silicone rubber, is inserted, which is filled with the ceramic mass 4 . Outer tube 2 and inner tube 1 taper to an order tip 5 . Since the interior of the application device is closed by a cap 7 , an excess pressure can be achieved by exerting a finger pressure on the finger pressure opening 3 , which allows the slip to escape at the application tip 5 . In order to be able to reduce a negative pressure that arises when the pressed-in inner tube 1 returns to the normal position, a ventilation valve 6 is seen before.

Zur Anpassung an die jeweiligen Arbeitsbedingungen kann die Auftragspitze füllfederhaltig geschlitzt oder pinselartig ausgebildet sein. Die Form der Spitze hängt von der Viskosität des Schlickers ab.The order peak can be adapted to the respective working conditions slotted fountain pen or brush-like design. The shape of the tip depends on the viscosity of the slip.

Da das elastische Innenrohr 1 in das Außenrohr 2 eingeschoben werden kann, ist es möglich, erfindungsgemäß den Schlicker beim Hersteller des Keramikpulvers an mischen und in das Innenrohr 1 einfüllen zu lassen, da beim Mischen im Zahn­ labor falsche Mischungsverhältnisse leicht möglich sind. Um einen gebrauchs­ fähigen Schlicker zu erhalten, muß das Innenrohr nur an beiden Enden dann aufge­ schnitten oder andersweitig geöffnet werden.Since the elastic inner tube 1 can be inserted into the outer tube 2 , it is possible, according to the invention, to mix the slip with the manufacturer of the ceramic powder and have it filled into the inner tube 1 , since incorrect mixing ratios are easily possible when mixing in the dental laboratory. In order to obtain a usable slip, the inner tube then only has to be cut at both ends or opened in another way.

Die Erfindung hat gegenüber anderen denkbaren Vorrichtungen den Vorteil, daß keinerlei mechanische Teile, wie Kolben, benötigt werden.The invention has the advantage over other conceivable devices that no mechanical parts such as pistons are required.
