Abstract

A device for tapping beer or the like from cans comprises a housing with an outlet closable by a tapping valve and an air pump. Attached to the housing is a piercing pipe which can be introduced into the can and forms a beer discharge channel which is in communication with the outlet. The air supplied by the air pump flows separately from the beer through lateral air outlet openings of the piercing pipe into the can above the level of the beer and applies pressure to the beer. The flow cross-section of the beer discharge channel in the piercing pipe is determined substantially throughout its entire length by the internal diameter of this pipe. A thin-walled sleeve of smaller external diameter than the internal diameter of the piercing pipe which separates the beer discharge channel from the flow path of the supplied air and which is sealed relative to this channel below the air outlet openings is provided in the upper region only of the piercing pipe.

Die Erfindung betrifft eine Vorrichtung zum Zapfen von Bier aus Behältern, insbesondere Dosen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for tapping beer from containers, in particular cans, according to the preamble of patent claim 1.

Eine derartige Vorrichtung ist aus DE-A-2 531 697 bekannt. Aus der US-A-1 995 098 ist ein Zapfhahn anderer Art bekannt, bei dem eine Art Verteilerstück durch eine rohrartige Verlängerung unmittelbar am Behälter befestigt wird. Schließlich zeigen GB-A-1 068 055 und US-A-3 327 899 flexible Schläuche zwischen der Luftpumpe und dem Anstechrohr einer Zapfvorrichtung.Such a device is known from DE-A-2 531 697. From US-A-1 995 098 a tap of a different type is known, in which a type of distributor piece is attached directly to the container by means of a tubular extension. Finally, GB-A-1 068 055 and US-A-3 327 899 show flexible hoses between the air pump and the tapping pipe of a dispenser.

Es ist Aufgabe der Erfindung, eine gattungsgemäße Vorrichtung so zu verbessern, daß sie leichter gefertigt und montiert werden kann.It is an object of the invention to improve a generic device so that it can be manufactured and assembled more easily.

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale A bis F des Patentanspruchs 1 gelöst.The object is achieved by the characterizing features A to F of claim 1.

Die nachstehende Beschreibung bevorzugter Ausführungsformen der Erfindung dient im Zusammenhang mit beiliegender Zeichnung der weiteren Erläuterung. Es zeigen:

  • Fig. 1 eine Querschnittsansicht einer Zapfvorrichtung für Bier oder andere kohlensäurenhaltigen Getränke;
  • Fig. 2 eine Draufsicht der Vorrichtung in Richtung des Pfeiles A in Fig. 1 und
  • Fig. 3 schematisch eine abgewandelte Ausführungsform einer Verteilerhülse.
The following description of preferred embodiments of the invention serves in conjunction with the accompanying drawings for further explanation. Show it:
  • 1 is a cross-sectional view of a tap for beer or other carbonated beverages.
  • Fig. 2 is a plan view of the device in the direction of arrow A in Fig. 1 and
  • Fig. 3 schematically shows a modified embodiment of a distributor sleeve.

Die in Fig. 1 dargestellte Zapfvorrichtung für Bier oder andere kohlensäurenhaltige Getränke umfaßt ein Gehäuse 1 mit einem in Fig. 1 nach rechts gerichteten Arm 2, in dessen Inneren eine von einem Schlauch 3 gebildete Bierausströmleitung verläuft, die ihrerseits an einem Auslaufende 4 des Armes 2 ins Freie mündet. An der Unterseite des Gehäuses 1 sind eine gehäusefeste Nase 5 und eine federnd bewegliche Nase 6 vorgesehen, mit deren Hilfe das Gehäuse 1 in an sich bekannter Weise auf den oberen Rand 7 einer mit Bier od. dgl. gefüllten Dose 8 aufgeklipst werden kann, die an ihrem Deckel 9 durch einen Stopfen 11 verschlossen ist.The dispensing device for beer or other carbonated drinks shown in FIG. 1 comprises a housing 1 with an arm 2 directed to the right in FIG. 1, inside which a beer outflow line formed by a hose 3 runs, which in turn runs at an outlet end 4 of the arm 2 leads into the open. On the underside of the housing 1, a housing-fixed nose 5 and a resiliently movable nose 6 are provided, with the aid of which the housing 1 can be clipped onto the upper edge 7 of a can 8 filled with beer or the like in a manner known per se is closed on its cover 9 by a stopper 11.

Vom Gehäuse 1 steht nach unten ein Anstechrohr 12 ab, dessen Länge etwa der Höhe der Dose 8 entspricht. Mit diesem Anstechrohr 12 wird in an sich bekannter Weise der entsprechend ausgebildete Stopfen 11 durchbohrt. Anschließend wird das Anstechrohr 12 so weit durch den Stopfen 11 hindurchgeschoben, bis das Gehäuse 1 mittels der Nasen 5, 6 auf den Dosenrand 7 aufgeklipst werden kann. Danach befindet sich die untere Öffnung 13 des Anstechrohres 12 knapp über dem Boden der Dose 8.A piercing tube 12 projects downward from the housing 1 and its length corresponds approximately to the height of the can 8. With this piercing tube 12, the appropriately designed plug 11 is pierced in a manner known per se. The piercing tube 12 is then pushed through the stopper 11 until the housing 1 can be clipped onto the can rim 7 by means of the lugs 5, 6. The lower opening 13 of the piercing tube 12 is then located just above the bottom of the can 8.

Das Gehäuse 1 trägt weiterhin an seiner Oberseite eine Luftpumpe 15 mit einem ortsfesten Kolbengehäuse 16, an dessen Außenseite eine das Gehäuse überfangende Haube 17 mit Griffpartie 18 gleitverschieblich ist. An der Oberseite des Kolbengehäuses 16 ist eine kreisscheibenförmige, flexible Membran 19 angeordnet, die mit ihrem Außenrand an der Innenseite der Haube 17 anliegt. Im Inneren des Kolbengehäuses 16 ist weiterhin eine Druckluftleitung, beispielsweise in Form eines Schlauches 21 vorgesehen, die an ein mit der oberen Wand des Kolbengehäuses 16 fest verbundenes Rückschlagventil 22 angeschlossen ist.The housing 1 also carries on its upper side an air pump 15 with a stationary piston housing 16, on the outside of which a hood 17 with a grip part 18 which slides over the housing is slidable. A circular disk-shaped, flexible membrane 19 is arranged on the upper side of the piston housing 16 and its outer edge lies against the inside of the hood 17. In the interior of the piston housing 16, a compressed air line, for example in the form of a hose 21, is also provided, which is connected to a check valve 22 which is firmly connected to the upper wall of the piston housing 16.

Wird die Haube 17 über dem Kolbengehäuse 16 nach oben geschoben, so löst sich der Rand der Membran 19 von der Innenseite der Haube 17, und es strömt von außen und unten Luft in den zwischen der Oberseite des Kolbengehäuses 16 und der Innenseite der Haube 17 gebildeten Raum ein. Wird nun die Haube 17 wieder nach unten geschoben, so legt sich der Rand der Membran 19 abdichtend an die Haube 17 an und die Luft zwischen Kolbengehäuse 16 und Haube 17 wird über das Rückschlagventil 22 in die vom Schlauch 21 gebildete Druckluftleitung überführt.If the hood 17 is pushed upwards over the piston housing 16, the edge of the membrane 19 detaches from the inside of the hood 17 and air flows from outside and below into the air formed between the top of the piston housing 16 and the inside of the hood 17 Space. If the hood 17 is now pushed down again, the edge of the membrane 19 seals against the hood 17 and the air between the piston housing 16 and the hood 17 is transferred via the check valve 22 into the compressed air line formed by the hose 21.

In das Gehäuse 1 ist fest, z.B. durch Einklebung oder Verschraubung, ein Verteilerstück 25 eingesetzt, welches mit einer nach unten abstehenden Hülse 26 frei in den obersten Bereich des Anstechrohres 12 unter Ausbildung eines verhältnismäßig breiten Ringspaltes zwischen Außenwand der Hülse und Innenwanddes Anstechrohres hineinragt. Das Verteilerstück 25 enthält oben ein Zapfventil 27, welches über einen schwenkbar am Gehäuse gelagerten Zapfhebel 28 betätigt werden kann. Das Zapfventil 27 wird von einer Feder 29 abdichtend gegen den oberen Rand der Hülse 26 gedrückt. Beim Niederdrücken des Zapfhebels 28 hebt sich das Ventil 27 von seinem Sitz an der Hülse 26 ab.In the housing 1 is fixed, e.g. by gluing or screwing, a distributor piece 25 is inserted, which projects freely with a sleeve 26 projecting downward into the uppermost region of the piercing tube 12, forming a relatively wide annular gap between the outer wall of the sleeve and the inner wall of the piercing tube. The distributor piece 25 contains a nozzle valve 27 at the top, which can be actuated via a nozzle lever 28 pivotally mounted on the housing. The nozzle valve 27 is pressed by a spring 29 sealingly against the upper edge of the sleeve 26. When the lever 28 is depressed, the valve 27 lifts off its seat on the sleeve 26.

Am Verteilerstück 25 sind weiterhin ein erster Schlauchnippel 31 zur Verbindung mit dem Schlauch 21 und ein zweiter Schlauchnippel 32 zur Verbindung mit dem Schlauch 3 ausgebildet.A first hose nipple 31 for connection to hose 21 and a second hose nipple 32 for connection with hose 3 are also formed on distributor piece 25.

Wie dargestellt ist das Anstechrohr 12 mit einem Außengewinde in ein Innengewinde einer ebenfalls am Verteilerstück 25 ausgebildeten Manschette 33 eingeschraubt, wobei zwischen Manschette 33 und einem Bund 34 am Anstechrohr 12 eine Ringdichtung 35 eingelegt ist.As shown, the piercing tube 12 is screwed with an external thread into an internal thread of a sleeve 33 which is also formed on the distributor piece 25, an annular seal 35 being inserted between the sleeve 33 and a collar 34 on the piercing tube 12.

Das Anstechrohr 12 weist seitliche Luftaustrittsöffnungen 36 auf, die im Betriebszustand der Vorrichtung unterhalb des Stopfens 11 und oberhalb des Spiegels 37 der in der Dose 8 befindlichen Flüssigkeit liegen. Unterhalb dieser Luftaustrittsöffnungen 36 ist der untere Rand der Hülse 26 mittels einer Ringdichtung 38 gegen die Innenwand des Anstechrohres 12 abgedichtet. Somit strömt beim Betätigen der Pumpe 15 die Luft über den Schlauch 21, den Nippel 31, den Ringraum zwischen Anstechrohr 12 und Hülse 26 und die Luftaustrittsöffnungen 36 in den Raum zwischen Flüssigkeitsspiegel 37 und Dosendeckel 9 ein. Hierdurch wird die Flüssigkeit in der Dose von oben her unter Druck gesetzt, so daß sie im Inneren des Anstechrohres 12 nach oben steigt, in die Hülse 26 eintritt und diese bis zum Zapfventil 27 füllt. Dabei vermittelt die Hülse 26 eine Trennung zwischen der zugeführten Luft und der Flüssigkeit. Wird nun durch Betätigung des Hebels 28 das Zapfventil 27 geöffnet, so gelangt unter der Wirkung des herrschenden Luftdruckes Flüssigkeit (Bier) über die Schlauchleitung 3 nach außen in ein bereitgehaltenes Gefäß.The piercing tube 12 has lateral air outlet openings 36 which, in the operating state of the device, lie below the stopper 11 and above the level 37 of the liquid in the can 8. Below these air outlet openings 36, the lower edge of the sleeve 26 is sealed against the inner wall of the piercing tube 12 by means of an annular seal 38. Thus, when the pump 15 is actuated, the air flows through the hose 21, the nipple 31, the annular space between the piercing pipe 12 and the sleeve 26 and the air outlet openings 36 into the space between the liquid level 37 and the can lid 9. As a result, the liquid in the can is pressurized from above, so that it rises inside the piercing tube 12, enters the sleeve 26 and fills it up to the nozzle 27. The sleeve 26 mediates a separation between the supplied air and the liquid. If the dispensing valve 27 is now opened by actuating the lever 28, this takes place under the effect of the prevailing air pressure Liquid (beer) via the hose line 3 to the outside in a prepared container.

Die beschriebene Ausbildung der Zapfvorrichtung hat gegenüber dem Stand der Technik folgende Vorteile: ein besonderes, enges, sich über die gesamte Länge des Anstechrohres 12 erstreckendes Steigrohr entfällt. Der Querschnitt des Bierausströmungskanales wird praktisch durch den verhältnismäßig großen Innendurchmesser des Anstechrohres 12, den ebenfalls noch relativ großen Innendurchmesser der Hülse 26 sowie den ebenfalls großen Durchmesser der Schlauchleitung 3 bestimmt. Da das gezapfte Bier auf seinem Weg von der Dose über das Anstechrohr 12 und die Hülse 26 keine engen Bereiche überwinden muß, strömt es in verhältnismäßig großer Menge jedoch mit kleiner Geschwindigkeit zum Auslaßende 4 der Vorrichtung. Infolgedessen entbindet das Bier beim Durchlaufen des Anstechrohres 12 und der Hülse 26 praktisch keine Kohlensäure. Es kann somit ohne Schaumbildung gezapft werden. Der Schaum bildet sich erst aus derjenigen Biermenge, die bereits in das zu füllende Gefäß eingeströmt ist. Daher kann gegenüber Vorrichtungen mit dem erwähnten, engen Steigrohr etwa um 30% schneller gezapft werden.The described design of the dispensing device has the following advantages over the prior art: a special, narrow riser pipe, which extends over the entire length of the piercing pipe 12, is omitted. The cross section of the beer outflow channel is practically determined by the relatively large inner diameter of the piercing tube 12, the likewise still relatively large inner diameter of the sleeve 26 and the likewise large diameter of the hose line 3. Since the draft beer does not have to overcome narrow areas on its way from the can via the tapping tube 12 and the sleeve 26, it flows in relatively large quantities at a low speed to the outlet end 4 of the device. As a result, the beer releases practically no carbon dioxide when it passes through the piercing tube 12 and the sleeve 26. It can therefore be tapped without foaming. The foam only forms from the amount of beer that has already flowed into the vessel to be filled. It is therefore possible to tap around 30% faster than devices with the narrow riser mentioned.

Folgende Abmessungen haben sich als besonders vorteilhaft erwiesen:

  • Innendurchmesser des Anstechrohres 12: zwischen 8 und 10 mm
  • Außendurchmesser der Hülse 26: zwischen 7,5 und 9,5 mm;
  • Innendurchmesser der Hülse 26: maximal 9 mm.
The following dimensions have proven to be particularly advantageous:
  • Inner diameter of the piercing tube 12: between 8 and 10 mm
  • Outer diameter of the sleeve 26: between 7.5 and 9.5 mm;
  • Inner diameter of the sleeve 26: maximum 9 mm.

Besonders bevorzugte Werte sind 9, 8 und 6 mm für den Innendurchmesser des Anstechrohres 12, den Außendurchmesser der Hülse 26 bzw. den Innendurchmesser dieser Hülse.Particularly preferred values are 9, 8 and 6 mm for the inside diameter of the piercing tube 12, the outside diameter of the sleeve 26 and the inside diameter of this sleeve.

Wie dargestellt, hat im Gegensatz zum Stand der Technik auch der die Luftzuführung vermittelnde Ringraum zwischen Anstechrohr 12 und Hülse 26 eine verhältnismäßig große Querschnittsfläche, so daß insoweit auch die Druckluftzufuhr erleichtert und verbessert ist.As shown, in contrast to the prior art, the annular space mediating the air supply between piercing tube 12 and sleeve 26 also has a relatively large cross-sectional area, so that the compressed air supply is also facilitated and improved.

Bei der in Fig. 1 dargestellten Ausführungsform der Erfindung ist die einen Teil des Verteilerstückes 25 bildende Hülse 26 fest mit dem Gehäuse 1 verbunden. Bei einer anderen bevorzugten Ausführungsform der Erfindung könnte die Hülse 26, welche die Trennung von Luft und Bier bewirkt, auch von den übrigen Funktionsteilen des Verteilerstückes 25, nämlich den Nippeln 31, 32 und der Aufnahme für das Zapfventil 27 getrennt ausgebildet werden. Eine solche Ausführungsform ist schematisch in Fig. 3 angedeutet. Eine der Hülse 26 in Fig. 1 entsprechende Hülse 126 ist in diesem Falle in das Anstechrohr 12 eingesteckt und unterhalb der Luftaustrittsöffnungen 26 fest und abgedichtet mit dem Rohr 12 verbunden. Am oberen (in Fig. 3 nicht mehr dargestellten) Ende von Anstechrohr 12 und Hülse 126 erfolgt in herkömmlicher Weise eine Abdichtung am Vorrichtungsgehäuse 1. Im übrigen funktioniert die Ausführungsform gemäß Fig. 3 ebenso wie die Ausführungsform gemäß Fig. 1.In the embodiment of the invention shown in FIG. 1, the sleeve 26 forming part of the distributor piece 25 is firmly connected to the housing 1. In another preferred embodiment of the invention, the sleeve 26, which effects the separation of air and beer, could also be formed separately from the other functional parts of the distributor piece 25, namely the nipples 31, 32 and the receptacle for the nozzle valve 27. Such an embodiment is indicated schematically in FIG. 3. In this case, a sleeve 126 corresponding to the sleeve 26 in FIG. 1 is inserted into the piercing tube 12 and is connected to the tube 12 in a tight and sealed manner below the air outlet openings 26. At the upper end (not shown in FIG. 3) of piercing tube 12 and sleeve 126, a seal is made on the device housing 1 in a conventional manner. Otherwise, the embodiment according to FIG. 3 functions just like the embodiment according to FIG. 1.

Bei einer weiteren Ausführungsform kann die Hülse 126 auch als loses Zwischenteil zwischen Anstechrohr 12 und Gehäuse 1 eingeführt sein.In a further embodiment, the sleeve 126 can also be inserted as a loose intermediate part between the piercing tube 12 and the housing 1.

Bei beiden zuletzt erwähnten Ausführungsformen sind dann die Nippel 31, 32 und die Aufnahme für das Zapfventil 27 in anderer Weise fest im Gehäuse ausgebildet, in welches auch das Anstechrohr 12, z.B. durch eine Schraubverbindung einsetzbar ist.In both of the last-mentioned embodiments, the nipples 31, 32 and the receptacle for the nozzle valve 27 are then embodied in a different manner in the housing, in which the piercing pipe 12, e.g. can be used by a screw connection.

Die im Zusammenhang mit Fig. 1 beschriebene Luftpumpe 14 mit der manuell verschieblichen Haube 17 kann auch durch einen anderen Gasdruckerzeuger ersetzt werden, beispielsweise durch eine Kohlensäurepatrone.The air pump 14 described in connection with FIG. 1 with the manually displaceable hood 17 can also be replaced by another gas pressure generator, for example by a carbon dioxide cartridge.

Wie aus Fig. 1 hervorgeht, ist erfindungsgemäß zwischen dem Nippel 31 des Verteilerstücks 25 und dem stationären Kolbengehäuse 16 der Luftpumpe 15 der die Druckluft-Zuführleitung bildende Schlauch 21 angeordnet. In diesen Schlauch 21 ist an seinem dem Kolbengehäuse 16 zugewandten Ende das Rückschlagventil 22 eingesetzt. Hierdurch werden die Vorteile erreicht, daß das Schlauchende, welches das Rückschlagventil 22 enthält, fest in seiner hierfür vorgesehenen Aufnahme 41 abgedichtet gehalten und gleichzeitig das Rückschlagventil 22 am Kolbengehäuse 16 fixiert ist. Ausbildung und Zusammenbau der Pumpe werden hierdurch besonders einfach, weil eine besondere Aufnahmeeinrichtung für das Rückschlagventil 22, die bisher vorgesehen werden mußte, entfällt. Der Schlauch 21 kann dabei auch durch eine andere Druckluftleitung, beispielsweise auch eine starre Leitung, ersetzt werden.Wie dargestellt, weist das Rückschlagventil 22 zur Abdichtung und Fixierung an seinem oberen Ende mehrere, umlaufende, sägezahnartige Rippen 42 auf.As is apparent from FIG. 1, according to the invention the hose 21 forming the compressed air supply line is arranged between the nipple 31 of the distributor piece 25 and the stationary piston housing 16 of the air pump 15. The check valve 22 is inserted into this hose 21 at its end facing the piston housing 16. This achieves the advantages that the hose end, which contains the check valve 22, is kept tightly sealed in its receptacle 41 provided for this purpose and, at the same time, the check valve 22 is fixed on the piston housing 16. This makes training and assembly of the pump particularly simple because a special receiving device for the check valve 22, which previously had to be provided, is dispensed with. The hose 21 can also be replaced by another compressed air line, for example also a rigid line. As shown, the check valve 22 has a plurality of circumferential, sawtooth-like ribs 42 for sealing and fixing at its upper end.
