Description

Die vorliegende Erfindung betrifft ein Belüftungsventil für Getränkedosen, insbesondere für die Bier enthaltenen Dosen eines Volumens von 51.The present invention relates to a ventilation valve for beverage cans, in particular for the beer contained cans with a volume of 51.

Bekannt sind für diese 5 Liter Getränkedosen, welche einen seitlich angeordneten Entleerungshahn aufweisen können, in ein oberes Spundloch einsetzbare Belüftungsventile, welche aus einem einteilig geformten Ventileinsatz und einer ebenfalls einteilig geformten elastischen Spundbüchse mit einem mit dem Ventileinsatz zusammenwirkenden Dichtwulst, einer zur Auflage auf den die Dosenöffnung umgebendem Randbereich des Dosendeckels dienenden Auskragung, einer unterhalb der Auskragung befindlichen und mit dem Rand der Dosenöffnung zusammenwirkenden Dichtfläche sowie eine den Rand der Dosenöffnung hintergreifenden Halterung bestehen.Known for these 5 liter beverage cans, which are arranged on the side Can have drain valve, ventilation valves that can be inserted into an upper bung hole, which consists of a one-piece valve insert and also one one-piece molded elastic bung with a valve insert cooperating sealing bead, one for resting on the surrounding the can opening The edge area of the can lid serving as a projection, one below the overhang and cooperating with the edge of the can opening Sealing surface and a behind the edge of the can opening Bracket exist.

Die Spundbüchse weist im in das Innenteil der Dose gerichteten Abschnitt eine seitliche Belüftungsöffnung auf. Der Ventileinsatz ist drehbeweglich gelagert und kann zwischen einer "Offen"- und einer "Geschlossen"-Stellung bewegt werden, wobei die Belüftungsöffnung freigegeben oder verschlossen wird.The sheet pile can has one in the section directed into the inner part of the can side ventilation opening. The valve insert is pivoted and can be moved between an "open" and a "closed" position, whereby the ventilation opening is opened or closed.

Der Nachteil der bekannten Belüftungsventile besteht darin, daß die Spundbüchse komplett aus elastischem Material geformt ist und daher eine optimale Dichtung der unter Druck stehenden Getränkedose nicht erreicht werden kann.The disadvantage of the known ventilation valves is that the sheet pile can is completely made of elastic material and therefore an optimal seal of the pressurized beverage can cannot be reached.

Auch das Einbringen der bekannten Belüftungsventile in das Spundloch der Dosen ist mit Problemen behaftet, da die aus weichem Material geformte Auskragung unter Krafteinwirkung nachgeben kann, so daß das gesamte Ventil in die Dose hineingedrückt wird.Also the introduction of the well-known ventilation valves in the bung of the cans is fraught with problems because the projection made of soft material underneath Force can give way, so that the entire valve in the can is pushed in.

Zur Festlegung der "Offen"- oder "Geschlossen"-Stellung dienen bei den bekannten Belüftungsventilen zwei in die Auskragung aus elastischem Material eingeformte Aussparungen, in welche eine am Ventileinsatz angeformte Lippe eingreift. Zusätzlich dient ein im Inneren der Spundbüchse angeordneter Ansatz zusammen mit den Kanten einer Aussparung im Ventileinsatz als Anschlag zur Festlegung der "Offen"- oder "Geschlossen"-Stellung.To determine the "open" or "closed" position are used in the known Ventilation valves two molded into the cantilever made of elastic material Recesses in which a lip formed on the valve insert engages. In addition, an approach arranged inside the sheet pile box serves together with the edges of a recess in the valve insert as a stop for fixing the "Open" or "closed" position.

Nachteilig daran ist, daß während der Drehbewegung des Öffnungsvorganges die Lippe am Ventileinsatz in das Material der Auskragung hineinragt, dieses verformt und somit der Öffnungsvorgang erschwert wird. Durch das elastische Material des Ansatzes im Inneren der Hülse ist die Funktion des Anschlags eingeschränkt. Ein Überdrehen des Ventileinsatzes kann nicht verhindert werden.The disadvantage of this is that during the rotational movement of the opening process Lip on the valve insert protrudes into the material of the projection, this deforms and thus the opening process is difficult. Due to the elastic material of the Approach inside the sleeve limits the function of the stop. On It cannot be prevented that the valve insert is overturned.

Eine genaue Definition des Anfangs- und Endpunkts der Drehbewegung des Ventileinsatzes ist ebenfalls nicht möglich, ein exaktes Öffnen und Schließen des Ventils kann somit nicht erfolgen.A precise definition of the start and end point of the rotary movement of the valve insert is also not possible, an exact opening and closing of the valve can not be done.

Der Ventileinsatz weist durch die Konstruktion des Anschlags eine sehr komplexe geometrische Form auf, die zu hohen Herstellungskosten führt. Zum anderen gestattet diese Form nur eine Drehrichtung des Ventileinsatzes innerhalb der Hülse.The valve insert is very complex due to the construction of the stop geometric shape, which leads to high manufacturing costs. On the other hand, allowed this shape only one direction of rotation of the valve insert within the sleeve.

Desweiteren sind aus der DE 3345619 Spundlochverschlüsse bekannt, die zur Aufnahme von Zapfarmaturen mit Anstechrohren dienen und auch zur Belüftung der Getränkedosen verwendet werden können, indem eine angeformte Platte durchstoßen wird.Furthermore, bunghole closures are known from DE 3345619, which are used for Serving tap fittings with piercing pipes and also for ventilation of the Beverage cans can be used by a molded plate is pierced.

Nachteilig ist hierbei, daß bei Verwendung eines seitlichen Entleerungshahn oder einer Zapfarmatur ohne Anstechrohr das Durchstoßen und somit das Belüften der Getränkedose nicht ohne Hilfsmittel erfolgen kann sondern dazu ein fester Gegenstand, wie z. B. Schlüssel oder Schraubendreher benötigt wird.The disadvantage here is that when using a side drain valve or a tap fitting without a piercing pipe to pierce and thus vent the Beverage can can not be done without tools, but rather a solid object, such as B. key or screwdriver is required.

Ein weiterer Nachteil ist, daß es bei Getränkedosen, die mit den bekannten Belüftungsventilen und einem seitlichen Entleerungshahn ausgestattet sind nicht möglich ist eine Zapfarmaturen mit Anstechrohr zu verwenden.Another disadvantage is that it is the case with beverage cans with the known ventilation valves and a side drain valve are not equipped it is possible to use a tap with a pipe.

Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, ein Belüftungsventil zu schaffen, daß eine optimale Dichtung gewährleistet, ein einfaches und exaktes Belüften von Getränkedosen sicherstellt und die Verwendung einer Zapfarmaturen mit Anstechrohr ermöglicht.The present invention has therefore set itself the task of a ventilation valve create that an optimal seal ensures a simple and accurate Ventilation of beverage cans ensures and the use of a tap with piercing pipe.

Die Lösung der Aufgabe gelingt durch ein Belüftungsventil für Getränkedosen mit einem in einer elastischen Spundbüchse radial beweglichen Ventileinsatz, wobei die Spundbüchse aus einem inneren dichtenden Weichteil und einem Hartteil in Form einer Hülse aufgebaut ist, wobei das Hartteil einen Rastmechanismus bestehend aus inneren Rastkeilen, einem äußeren Flansch sowie einem dazwischen liegenden Dichtungsring aufweist, wobei der dem äußeren Flansch gegenüberliegende Rand der Hülse durch eine angeformte Platte verschlossen ist und die Hülse eine Axialbohrung mit mindestens einem mit dem Ventileinsatz zusammenwirkenden Dichtwulst des Weichteils aufweist und wobei die Spundbüchse im unteren Abschnitt, welcher in das Doseninnere reicht eine das Hart- und Weichteil durchgreifende seitliche Bohrung aufweist, wobei erfindungsgemäß der radial bewegliche Ventileinsatz ein im wesentlichen als Platte gestaltetes Griffteil mit einem zentrisch daran angeformten Ansatz und einen Korb umfaßt, in welchen der Ansatz eingreift, wobei der Ansatz mindestens eine Fläche aufweist, die mit der Innenwandung des Weichteils der Hülse einen Kanal bildet. Der Korb weist mindestens eine Dichtfläche auf, welche zusammen mit der durch das Weichteil gebildeten Innenwandung der Hülse die seitliche Bohrung gegen die Flüssigkeit abdichtet und mindestens eine Fläche die mit der Innenwandung des Weichteils der Hülse einen Kanal bildet. Die Platte des Griffteils weist Ausnehmungen auf, welche mit der Oberfläche des äußeren Flansches einen parallel dazu verlaufenden Kanal bilden. Desweiteren ist an die Platte des Griffteils ist an der Unterseite ein Nocken angeformt, der in eine Aussparung im äußeren Flansch eingreift. Die an das Hartteil angeformte Platte weist Sollbruchstellen auf.The problem can be solved with a ventilation valve for beverage cans a radially movable valve insert in an elastic sheet pile head, the Sheet pile sleeve made of an inner sealing soft part and a hard part in shape a sleeve is constructed, the hard part consisting of a locking mechanism inner locking wedges, an outer flange and an intermediate one Sealing ring, the edge opposite the outer flange the sleeve is closed by a molded plate and the sleeve is a Axial bore with at least one interacting with the valve insert Has sealing bead of the soft part and the bung in the lower section, which extends into the inside of the can through the hard and soft part has lateral bore, the radially movable according to the invention Valve insert a handle part designed essentially as a plate with a central integrally formed neck and a basket in which the neck engages, wherein the approach has at least one surface that is with the inner wall of the Soft part of the sleeve forms a channel. The basket has at least one sealing surface on which, together with the inner wall formed by the soft part Sleeve seals the side hole against the liquid and at least one Surface that forms a channel with the inner wall of the soft part of the sleeve. The Plate of the handle part has recesses which match the surface of the outer flange form a parallel channel. Furthermore is a cam is formed on the underside of the plate of the handle part, which cam in a Recess engages in the outer flange. The plate molded onto the hard part has predetermined breaking points.

Die Wirkungsweise ist dabei folgende. Der Ventileinsatz besteht erfindungsgemäß aus einem Griffteil mit Ansatz und einem Korb in welchen der Ansatz eingreift. Der Ventileinsatz als ganzes wird in das Innere der Hülse eingeführt. Der Korb weist mindestens eine Dichtfläche auf, welche im Inneren der Hülse die seitliche Bohrung in der Hülse in der "Geschlossen"-Stellung des Ventils zur Flüssigkeit hin abdichtet sowie mindestens eine Fläche, welche mit der Innenwandung der Hülse einen Kanal bildet, durch welchen ein Druckausgleich mit der äußeren Atmosphäre in der "Offen"-Stellung des Ventils erfolgen kann. Der Ansatz des Griffteils ist an eine Platte angeformt, die mit dem äußeren Flansch der Spundbüchse im wesentlichen bündig abschließt. An der Unterseite der Platte ist ein Nocken angeformt welcher in eine Aussparung im äußeren Flansch der Spundbüchse eingreift. Diese Aussparung ist vorteilhaft im wesentlichen halbkreisförmig gestaltet. Die Enden der Aussparung bilden einen Anschlag für den Nocken und somit eine Begrenzung der Drehbewegung des Ventileinsatzes.The mode of action is as follows. The valve insert is according to the invention from a handle with attachment and a basket in which the attachment engages. The The valve insert as a whole is inserted into the interior of the sleeve. The basket points at least one sealing surface, which in the interior of the sleeve, the lateral bore seals in the sleeve in the "closed" position of the valve to the liquid and at least one surface which has a channel with the inner wall of the sleeve forms, through which a pressure equalization with the external atmosphere in the "open" position of the valve can be done. The attachment of the handle part is on a plate integrally formed, which is essentially flush with the outer flange of the sheet pile completes. A cam is formed on the underside of the plate, which cam in one Recess engages in the outer flange of the sheet pile. This recess is advantageously designed substantially semicircular. The ends of the recess form a stop for the cam and thus a limitation of the Rotary movement of the valve insert.

Darüber hinaus weist die Platte erfindungsgemäß an der Unterseite Ausnehmungen auf, welche mit der Oberfläche des äußeren Flansches einen parallel dazu verlaufenden Kanal bilden, welcher mit dem durch die Innenwandung der Hülse und den Abflachungen des Ansatzes sowie des Korbs geformten Kanal verbunden ist und somit den gewünschten Druckausgleich bei Betätigung des Ventils zwischen dem Doseninneren und der Atmosphäre ermöglicht.In addition, according to the invention, the plate has recesses on the underside on which is parallel to the surface of the outer flange form extending channel, which with the through the inner wall of the sleeve and the flats of the approach and the basket-shaped channel is connected and thus the desired pressure compensation when the valve is actuated between the inside of the can and the atmosphere.

In dem Fall daß die Vorrichtung nicht zum Belüften der Getränkedose sondern zur Aufnahme einer Zapfarmatur mit Anstechrohr dienen soll, wird das Griffteil mit Ansatz aus der Spundbüchse herausgezogen. Der Korb verbleibt in diesem Fall im Inneren der Hülse und wird beim Durchstoßen der Platte mit dem Anstechrohr in das Doseninnere gestoßen. Die an der zum Doseninneren gerichteten Unterseite der Hülse angeformte Platte weist Sollbruchstellen auf, welche ein leichtes Durchstoßen der Platte ermöglichen. In einer weiteren bevorzugten Ausführungsform der Erfindung ist anstelle der angeformten Platte die Hülse durch einen über Klemmwirkung gehaltenen Stopfen verschlossen, wodurch eine Zapfarmatur mit Anstechrohr besonders leicht eingeführt werden kann.In the event that the device is not for ventilating the beverage can but for The handle part with shoulder is intended to accommodate a tap fitting with a piercing pipe pulled out of the sheet pile. In this case, the basket remains inside the sleeve and is pierced with the piercing tube into the Bumped inside the can. The on the underside of the The molded-on plate has predetermined breaking points which are easy to pierce allow the plate. In a further preferred embodiment of the Invention is instead of the molded plate, the sleeve by a Clamping stopper plug closed, creating a tap with Piercing tube can be inserted particularly easily.

In einer besonders bevorzugten Ausgestaltung der Erfindung weist der Korb an der Unterseite eine Schneide auf, die die Sollbruchstelle der angeformten Platte beim Einstechen der Zapfarmatur anritzt und so das Durchstoßen der Platte erleichtert. In a particularly preferred embodiment of the invention, the basket on the Underside of a cutting edge that the predetermined breaking point of the molded plate at Pierce the tap fitting and make it easier to pierce the plate.

Der Korb kann an der Unterseite ein radiales Führungsglied aufweisen, wodurch zum einen das Einführen des Ventileinsatzes in die Hülse erleichtert, eine bessere Führung bei der Drehbewegung des Ventils erreicht wird und zum anderen der Korb positionsgenau gehalten werden kann, um eine optimale Dichtung zu gewährleisten.The basket can have a radial guide member on the underside, which leads to an easier insertion of the valve insert into the sleeve, a better one Guidance is achieved in the rotary movement of the valve and secondly the basket can be held in position to ensure an optimal seal.

Das Führungsglied kann als an der Unterseite des Korbs angeformte Scheibe mit einem Durchmesser, der im wesentlichen dem Durchmesser der Axialbohrung Hülse entspricht, gestaltet sein.The guide member can be formed as a disc on the underside of the basket a diameter that is essentially the diameter of the axial bore sleeve corresponds to be designed.

Bevorzugt ist das Führungsglied jedoch als Ausnehmung im unteren Bereich des Korbs gestaltet, in welche ein Fortsatz der an das Hartteil angeformten Platte eingreift.However, the guide member is preferred as a recess in the lower region of the Designed basket, in which an extension of the molded onto the hard part engages.

Auch der Ansatz des Griffteils kann Führungsglieder aufweisen, die mit dem Dichtwulst der Hülse zusammenwirken und einer weitere Verbesserung des Verhaltens des Ventileinsatzes bewirken.The approach of the handle part can have guide members that with the Sealing bead of the sleeve interact and further improve behavior of the valve insert.

An der Platte des Griffteils ist vorteilhaft eine aufbiegbare Lasche angeordnet, welche zur bequemeren Betätigung des Ventils aufgebogen werden kann. Die Lasche greift vorzugsweise in einen Durchbruch im Rand des äußeren Flansches der Hülse ein.On the plate of the handle part a bendable tab is advantageously arranged, which can be bent open for more convenient operation of the valve.
