Description

BeschreibungDescription

Vorliegend wird eine Erfindung beschrieben, die eine Mischkapsel mit Ausspritzöffnung betrifft, welche vorwiegend im Dentalbereich und für Zemente aller Art eingesetzt werden kann. Es hat nicht an Versuchen gefehlt, solche Kapseln anzugeben und herzustellen, jedoch wurde das wesentliche Problem dieser Kapseln für Dentalzemente, nämlich die Abschirmung des Zements gegen die die Kapsel umgebende Luftfeuchtigkeit einerseits und die Feuchtigkeit der Anmischflüssigkeit andererseits, bislang nicht gelöst. Dies schlägt sich insbesondere darin nieder, dass die nach dem Stand der Technik verkapselten Zemente, insbesondere nach Öffnung der die Kapsel umgebenden Packung, nur sehr begrenzt haltbar sind.An invention is described here which relates to a mixing capsule with a discharge opening, which can be used primarily in the dental field and for cements of all kinds. There has been no lack of attempts to specify and produce such capsules, however, the main problem of these capsules for dental cements, namely the shielding of the cement against the humidity surrounding the capsule on the one hand and the moisture of the mixing liquid on the other hand, has not yet been solved. This is reflected in particular in the fact that the cements encapsulated according to the state of the art have a very limited shelf life, especially after the packaging surrounding the capsule has been opened.

Der Erfindung daher liegt die Aufgabe zugrunde, eine Mischkapsel zu schaffen, es bei gleichzeitiger leichter Aktivierbarkeit ermöglicht, die Komponenten getrennt voneinander und vollständig dicht gegenüber der Umgebung, aufzubewahren.The invention is therefore based on the object of creating a mixing capsule that, while at the same time being easy to activate, enables the components to be stored separately from one another and completely sealed from the environment.

Ferner soll der Mischraum möglichst gross gestaltet werden, damit bei dem durch die in den Zahnarztpraxen vorhandenen, bekannten Ausbringgeräte vorgegebenen maximalen Kapseldurchmesser, eine möglichst grosse Mischgutmenge angemischt werden kann. Zusätzlich soll eine entsprechend grosse Flüssigkeitsmenge in den Mischraum eingepresst werden, die zum Anmischen einer grossen Menge von Pulver erforderlich ist.Furthermore, the mixing chamber should be designed to be as large as possible so that the largest possible quantity of mixture can be mixed with the maximum capsule diameter specified by the known dispensing devices available in dental practices. In addition, a correspondingly large quantity of liquid should be pressed into the mixing chamber, which is required to mix a large quantity of powder.

Zudem soll die Entleerung des Komponentenraumes (8) vollständig erfolgen, damit die angemischte Masse im vorschriftsmässigen Verhältniss vorliegt.In addition, the component chamber (8) should be completely emptied so that the mixed mass is present in the prescribed ratio.

Es wurden Kapseln beschrieben ( DE 39 20 537, DE 37 18 326 Al, DE 38 32 757), bei denen die zu mischende erste Komponente, zumeist eine Flüssigkeit, in Folienbehältern innerhalb der Kapsel aufbewahrt wird. Die Herstellung von hinreichend grossen Folienbehältern zum Auspressen innerhalb der Kapsel ist jedoch herstellungstechnisch schwierig und teuer. Die bekanntenCapsules have been described (DE 39 20 537, DE 37 18 326 A1, DE 38 32 757) in which the first component to be mixed, usually a liquid, is stored in foil containers inside the capsule. However, the production of sufficiently large foil containers for squeezing inside the capsule is technically difficult and expensive. The known

Folienbehälter können andererseits nicht beliebig vergrössert werden.On the other hand, foil containers cannot be enlarged at will.

Die nach dem Stand der Technik für Mischkapseln mit Ausspritzdüse zum Verschluss des Mischraumkörpers verwendeten Stifte, bieten keine Gewähr für den dichten Verschluss des Mischraumes (11). Andererseits muss auch das problemlose Öffnen des Mischraumes zum Ausbringen der angemischten Masse gewährleistet sein, die erfindungsgemässe Konstruktion, bei der der Dorn (12) zunächst die Membran (3), später die Membran (20a) durchstösst, bietet für beide Forderungen an die Mischkapsel eine exzellente Lösung.The pins used according to the state of the art for mixing capsules with ejection nozzles to close the mixing chamber body do not guarantee that the mixing chamber (11) is sealed tightly. On the other hand, the problem-free opening of the mixing chamber for dispensing the mixed mass must also be guaranteed; the design according to the invention, in which the mandrel (12) first pierces the membrane (3) and later the membrane (20a), offers an excellent solution for both requirements of the mixing capsule.

Ein Aspekt der erfindungsgemässen Lösung stellt die Aufbewahrung der flüssigen Komponente,- ohne weitere Ummantelung etwa durch einen Folienbehälter - , dar. Um einen dichten Abschluss zu erreichen muss daher, nach einem weiteren Aspekt der Erfindung, der Kolben (4) dicht gegen den Behälter (2) angebracht werden. Gleichzeitig darf jedoch nicht die leichte, insbesondere manuelle Aktivierbarkeit verloren gehen. Dabei liegt erfindungsgemäss im Kontaktbereich zwischen Kolben und Flüssigkeit (8) eine durch Dichtlippen erzeugte Dichtigkeit vor, während zusätzlich im gegenüberliegenden Teil des Kolbens die Dichtigkeit nach aussen durch eine Verschweissung oder Verklebung erreicht wird.One aspect of the solution according to the invention is the storage of the liquid component - without further covering, for example with a foil container. In order to achieve a tight seal, according to a further aspect of the invention, the piston (4) must be attached tightly against the container (2). At the same time, however, the easy, particularly manual, activation must not be lost. According to the invention, in the contact area between the piston and the liquid (8) there is a tight seal created by sealing lips, while in the opposite part of the piston the tightness to the outside is additionally achieved by welding or gluing.

Es würde sich, wie dargelegt, nachteilig auswirken, wenn der Kolben (4) nicht vollständig in das Behältnis (2) hineinrutschen würde, da dann das Mischungsverhältnis zwischen Pulver und Flüssigkeit nicht mehr stimmen würde. Nach einem weiteren Aspekt der erfindungsgemässen Lösung wird zu diesem Zweck der Kolben (4) auf der dem Behälter (2) zugewandten Seite mit einer oder mehreren, vorzugsweise zirkulären oder semizizkulären Verzahnungen versehen. Dadurch rutscht der Kolben während der Vibrationsmischung stets tiefer in den Behälter (2),ohne dass er wieder herausrutschen kann.As explained, it would have a disadvantageous effect if the piston (4) did not slide completely into the container (2), since the mixing ratio between powder and liquid would then no longer be correct. According to a further aspect of the solution according to the invention, the piston (4) is provided with one or more, preferably circular or semi-circular, toothings on the side facing the container (2). As a result, the piston slides deeper into the container (2) during the vibration mixing, without being able to slip out again.

Nun beschreibt DE 39 20 537 eine Mischkapsel, deren Prinzip der vorliegend beschriebenen Lösung ähnelt. Wesentliche Unterschiede,Now DE 39 20 537 describes a mixing capsule whose principle is similar to the solution described here. Important differences,

die durch die Lösung der Probleme aller bekannten Äiischkapseln begründet sind, liegen jedoch vor:However, there are solutions to the problems of all known capsules:

So wird zum Zwecke der Aktivierung bei der erfindungsgemässen Kapsel der Kolben (2) nicht vom Rand (13) gelöst. Diese Trennung erfolgt erst später und darüber hinaus , nach einem weiteren Aspekt der Erfindung, nicht zwingend direkt am hinteren Rand, sondern, in vorteilhafter Weise, im Bereich des Übergangs (22) zur Membranseite. Die hat den erheblichen Vorteil, dass die Aktivierung der Kapsel aufgrund des geringen Kraftaufwandes manuell erfolgen kann, da insbesondere der Kolben (4) nur bis auf das Niveau des Ringes (10) vorgeschoben werden muss.For the purpose of activation, the piston (2) is not detached from the edge (13) in the capsule according to the invention. This separation only takes place later and, in addition, according to a further aspect of the invention, not necessarily directly at the rear edge, but rather, advantageously, in the area of the transition (22) to the membrane side. This has the considerable advantage that the activation of the capsule can be carried out manually due to the low expenditure of force, since the piston (4) in particular only has to be pushed forward to the level of the ring (10).

Ferner benötigt die erfindungsgemässe Kapsel kein Folienkissen mehr, was herstellungstechnisch eine wesentliche Erleichterung und Verbilligung darstellt.Furthermore, the capsule according to the invention no longer requires a foil cushion, which represents a significant simplification and reduction in cost in terms of manufacturing technology.

Zudem ist der Kolben (4) der erfindungsgemässen Kapsel dicht (verschweisst oder geklebt) mit dem Ring (13) und/oder dem Mischkörper verbunden.In addition, the piston (4) of the capsule according to the invention is tightly connected (welded or glued) to the ring (13) and/or the mixing body.

Ein wesentlicher Unterschied mit grosser praktischer Bedeutung ist, dass durch die vorliegend geschilderte Konstruktion die Aktivierung nicht mehr mit einem Werkzeug erfolgen muss, was bei dem in DE 39 20 537 beschriebenen Konstruktionsprinzip zwingend nötig ist. Denn der Ring (13) bleibt bei der erfindungsgemässen Kapsel auch während des Anmischens stets in seiner Position.A significant difference with great practical significance is that the design described here means that activation no longer has to be carried out with a tool, which is absolutely necessary with the design principle described in DE 39 20 537. This is because the ring (13) in the capsule according to the invention always remains in its position even during mixing.

Die Erfindung wird im folgenden näher unter Bezugnahme auf die Zeichnung erläutert, die vorteilhafte Aufführungsbeispiele veranschaulicht:The invention is explained in more detail below with reference to the drawing, which illustrates advantageous embodiments:

Fig. 1 a zeigt den Längsschnitt der Kapsel im aktivierten Zustand.Fig. 1 a shows the longitudinal section of the capsule in the activated state.

Der Dorn (12) hat bereits die Membran (3) durchstossen und die Flüssigkeit aus dem Raum (8) in den Mischraum (11) gepresst.The mandrel (12) has already pierced the membrane (3) and pressed the liquid from the chamber (8) into the mixing chamber (11).

Zu Beginn des aktivierungsvorganges ist der Dichtungsrand (10) vom Kolben (4) abgebrochen worden.At the beginning of the activation process, the sealing edge (10) was broken off from the piston (4).

In einer vorteilhaften Ausführung der Erfindungsgemässen Lösung bleibt jedoch der Dichtungsring (10) am Ring (13) oder am Kapselkörper (1) hängen, je nach dem, wo der Ring konstruktionsgemäss befesttigt wurde.In an advantageous embodiment of the solution according to the invention, however, the sealing ring (10) remains attached to the ring (13) or to the capsule body (1), depending on where the ring was attached according to the design.

Nach der initialen Aktivierung wird die Kapsel in einen handelsüblichen Vibrationsmischer eingelegt. Nach dem Anmischvorgang, der üblicherweise ca. 5-20 see. in anspruch nimmt, wird die Kapsel mit den Rillen (9) oder dem Vorsprung (14) in das Auspressgerät (19) eingesetzt. Durch Vorschub des StempelsAfter the initial activation, the capsule is placed in a commercially available vibration mixer. After the mixing process, which usually takes about 5-20 seconds, the capsule is placed with the grooves (9) or the projection (14) in the squeezing device (19). By pushing the plunger

(5) in der gezeigten Pfeilrichtung, werden Kolben (4) und Behälter (2) gemeinsam, oder Kolben (4) mit dem abgebrochenen Behälterboden(5) in the direction of the arrow shown, piston (4) and container (2) together, or piston (4 with the broken container bottom

(6) in den Mischraum (11) vorgeschoben, wobei der Dorn (12) die Membran (20a) durchstösst und der Behälter (2) vom Ring (13) abreiset.(6) is pushed into the mixing chamber (11), whereby the mandrel (12) pierces the membrane (20a) and the container (2) breaks away from the ring (13).

Fig. Ib zeigt die erfindungsgemässe Kapsel im Urzustand.Fig. Ib shows the capsule according to the invention in its original state.

Der Dorn (12) ist unweit der später zu durchstossenden Membran (3) platziert.The mandrel (12) is placed not far from the membrane (3) that will later be pierced.

Fig. 2a zeigt Kolben und Behälter in der maximalen Vorschubposition in der leeren Kapsel. Der Dorn (12), der vorteilhafterweise etwa rinnenförmig ausgebildet ist, kommt in der Ausspritzöffnung (7) zu liegen und verlegt diese dabei nicht.Fig. 2a shows the piston and container in the maximum advance position in the empty capsule. The mandrel (12), which is advantageously designed in a groove-like manner, comes to rest in the ejection opening (7) and does not block it.

Fig.2b zeigt die erfindungsgemässe Kapsel von aussen im nichtaktivierten Zustand.Fig.2b shows the capsule according to the invention from the outside in the non-activated state.
