Definitions
- the invention relates to a tap with a foam choke for removing liquid from a container with a plastic bushing, in which a piston is guided and which has a passage opening for the liquid, which closes the piston in a retracted locking position and in an extended removal position releases.
- Such taps are from the DEU 298 21 780, DE 198 25 929 A1 .
- Beer is traditionally tapped with CO 2 under overpressure. This technique is widely used in gastronomy. It has the advantage that the beer comes with CO 2 substantially saturated to the customer. This is unsurpassed for the freshness, quality and taste of the beer.
- a party keg of beer can be emptied by gravity with simultaneous pressure equalization without CO 2 .
- a tap integrated into a party keg of the type mentioned was developed.
- the tap is used in conjunction with a manual pressure relief valve in a bunghole at the top of the barrel. The consumer can aerate the barrel through the valve and bring about an unpressurized evacuation by gravity alone.
- the disadvantage here is that the beer comes into contact with atmospheric oxygen, and that outgasses CO 2 from the beer. Remedy is seen in a CO 2 dispenser, which is located inside the party keg and gives off a controlled CO 2 overpressure into the headspace of the keg the first time it is taped.
- the CO 2 dispenser is activated by the consumer in exactly the same way as the pressure equalization valve at the top of the drum. The CO 2 overpressure ensures that the existing CO 2 remains dissolved in the beer and no oxygen enters the headspace of the barrel.
- the object of the invention is to provide a foam choke, with which a tap of the type mentioned in a simple, easy to install and retrofit can adapt to a pin with CO 2+ under pressure, so that beer and foam in an appropriate ratio be issued.
- the foam choke that accomplishes this task consists of a hood which can be placed in front of the passage opening on the bushing of the tap, which covers the passage opening and which encloses a labyrinth channel with the bushing, which at one end is open towards the interior of the container and which ends at the other end into the passage opening.
- the labyrinth channel has a meandering course.
- the open end of the labyrinth channel is near the outer end of the bushing. This is important for the emptying of the container.
- the tap is located just above the bottom of the container, which is tilted to remove the liquid residue. In this case, a liquid level must adjust at the open end of the labyrinth channel.
- the labyrinth channel can be formed both on the outer jacket of the liner, as well as on the inner surface of the hood.
- the labyrinth channel may end in a tap hole through the hood or leak at an end face of the hood.
- the opening of the labyrinth channel is even closer to the end of the bushing.
- the hood can be clipped onto the bushing.
- the hood can be both fully cylindrical, as well as partially cylindrical.
- the hood has a wrap angle of more than 180 °, preferably about 220 °. It holds so under slight spread by inherent elasticity of the liner.
- the liner is provided with ribs on its outer shell.
- the hood of the foam choke has recesses that fit over these ribs for positioning.
- the tap consists of a liner 10, a piston 12 and a foam throttle 14th
- the bush 10 has a circular cylindrical cup body 16, the bottom 18 is closed at its inner end.
- a conically expanding bung made of elastic material is formed, which has a flange-like outer bearing part 20, a recessed behind it circumferential sealing part 22 and located in front of the sealing part 22, circumferential conical locking part 24 whose diameter is greater than that the sealing part 22.
- the tap is pressed as a completely pre-assembled unit of bush 10, piston 12 and foam throttle 14 in the round opening of a container containing a liquid to be tapped. It is a pressureless or pressurized liquid that may contain carbon dioxide. Specifically, it is about the tapping of drinks, especially beer, from barrels, small barrels (party kegs) or cans.
- the nozzle is pressed with the cup body 16 and the conical latching portion 24 of the bushing 10 in the opening of the container.
- the peripheral sealing portion 22 receives the edge of the opening under seal, so that it comes to rest between the flange-like bearing section 20 and the latching portion 24 of the bushing 10, with the latter engages at the edge of the opening.
- the liner 10 has in the jacket wall of its cup body a passage opening 28 for the liquid to be tapped.
- the piston is a cylindrical hollow body whose shell wall at the inner end of the piston has an inlet opening 30, and at the outer end of the piston an outlet opening 32 for the liquid.
- the piston 12 takes a retracted into the bush 10 locking position (see. Fig. 1 ), in which he closes the passage opening 28 of the bush 10 tightly.
- the inlet opening 30 reaches the height of the passage opening 28, and liquid flows through the interior of the piston towards its outlet opening 32.
- the foam throttle 14 is a partially cylindrical hood made of plastic.
- the hood is clipped outside the passage opening 28 on the cup body 16 of the bushing 10 so that it covers the passage opening 28.
- the hood has a wrap angle of about 220 ° -. It sits slightly spread apart by its own elasticity on the cup body 16 of the bushing 10 fixed.

Abstract
Description
Die Erfindung betrifft einen Zapfhahn mit einer Schaumdrossel zur Entnahme von Flüssigkeit aus einem Behälter mit einer Laufbuchse aus Kunststoff, in der ein Kolben geführt ist und die eine Durchtrittsöffnung für die Flüssigkeit aufweist, die der Kolben in einer eingefahrenen Sperrstellung dicht verschließt und in einer ausgefahrenen Entnahmestellung freigibt.The invention relates to a tap with a foam choke for removing liquid from a container with a plastic bushing, in which a piston is guided and which has a passage opening for the liquid, which closes the piston in a retracted locking position and in an extended removal position releases.
Derartige Zapfhähne sind aus dem DEU 298 21 780,
Bier wird traditionell mit CO2 unter Überdruck gezapft. Diese Technik ist in der Gastronomie weit verbreitet. Sie hat den Vorteil, daß das Bier mit CO2 im wesentlichen gesättigt zum Abnehmer kommt. Das ist für Frische, Qualität und Geschmack des Biers unübertroffen.Beer is traditionally tapped with CO 2 under overpressure. This technique is widely used in gastronomy. It has the advantage that the beer comes with CO 2 substantially saturated to the customer. This is unsurpassed for the freshness, quality and taste of the beer.
Mit Partyfässern für Bier wurde ursprünglich das Konzept verfolgt, die Zapftechnik mit CO2 in den Hausgebrauch zu bringen. Es gibt Zapfarmaturen mit CO2-Patronen, die ein Anstechrohr haben, das durch ein Spundloch an der oberen Kuppe des Partyfasses bis an dessen Boden eingeführt wird. Es wird CO2 unter Überdruck in den Kopfraum des Fasses eingespeist, um das Bier durch das Anstechrohr hochzufördern und auszugeben. Dabei kann die Qualität des Biers beeinträchtigt werden, da der CO2-Überdruck nicht geregelt ist. Ist der Druck zu niedrig, so gast CO2 aus dem Bier aus, und das Bier wird schal. Ist der Druck zu hoch, so tritt eine Überkarbonatisierung des Biers ein, mit der eine Verschlechterung des Geschmacks einhergeht. Viele Abnehmer scheuen auch den Umgang mit CO2-Patronen und das als umständlich und kostenträchtig empfundene Zapfen damit.With beer beer kegs, the concept of bringing the tap technology into home use with CO 2 was originally pursued. There are dispensers with CO 2 cartridges that have a piercing tube that is inserted through a bunghole at the top of the party keg to the bottom. It is CO 2 fed under pressure in the headspace of the barrel to hochzufördern the beer through the tapping tube and spend. The quality of the beer can be affected, since the CO 2 overpressure is not regulated. If the pressure is too low, CO 2 is released from the beer, and the beer becomes stale. If the pressure is too high, overcarbonation of the beer occurs, accompanied by deterioration of the taste. Many customers also shy away from handling CO 2 cartridges and the cumbersome and costly pin.
Ein Partyfaß Bier läßt sich ohne CO2 durch Schwerkraftwirkung bei gleichzeitigem Druckausgleich entleeren. Zu diesem Zweck wurde ein in ein Partyfaß integrierter Zapfhahn der eingangs genannten Art entwikkelt. Der Zapfhahn kommt zusammen mit einem von Hand zu betätigenden Druckausgleichsventil in einem Spundloch an der oberen Kuppe des Fasses zum Einsatz. Der Verbraucher kann das Faß über das Ventil belüften und eine drucklose Entleerung allein durch die Schwerkraft herbeiführen.A party keg of beer can be emptied by gravity with simultaneous pressure equalization without CO 2 . For this purpose, a tap integrated into a party keg of the type mentioned was developed. The tap is used in conjunction with a manual pressure relief valve in a bunghole at the top of the barrel. The consumer can aerate the barrel through the valve and bring about an unpressurized evacuation by gravity alone.
Nachteilig dabei ist, daß das Bier mit Luftsauerstoff in Kontakt kommt, und daß CO2 aus dem Bier ausgast. Abhilfe wird in einem CO2-Spender gesehen, der sich im Innern des Partyfasses befindet und bei erstmaligem Zapfen einen geregelten CO2-Überdruck in den Kopfraum des Fasses abgibt. Der CO2-Spender wird von dem Verbraucher genauso aktiviert, wie derzeit das Druckausgleichsventil an der Kuppe des Fasses. Der CO2-Überdruck gewährleistet, daß das vorhandene CO2 im Bier gelöst bleibt und kein Sauerstoff in den Kopfraum des Fasses gelangt.The disadvantage here is that the beer comes into contact with atmospheric oxygen, and that outgasses CO 2 from the beer. Remedy is seen in a CO 2 dispenser, which is located inside the party keg and gives off a controlled CO 2 overpressure into the headspace of the keg the first time it is taped. The CO 2 dispenser is activated by the consumer in exactly the same way as the pressure equalization valve at the top of the drum. The CO 2 overpressure ensures that the existing CO 2 remains dissolved in the beer and no oxygen enters the headspace of the barrel.
Für den CO2-Überdruck im Kopfraum des Fasses werden ca. 0,6 bis 0,8 bar angestrebt. Gegenüber dem derzeitigen Stand, das Faß mit Druckausgleich bei Atmosphärendruck allein durch die Schwerkraft zu entleeren, bedeutet das eine deutliche Erhöhung des Förderdrucks. Die Konsequenz ist, daß praktisch nur noch Schaum gezapft wird.For the CO 2 overpressure in the headspace of the barrel approx. 0.6 to 0.8 bar are aimed for. Compared to the current state, to empty the barrel with pressure equalization at atmospheric pressure solely by gravity, this means a significant increase in the delivery pressure. The consequence is that practically only foam is tapped.
Aufgabe der Erfindung ist es, eine Schaumdrossel zu schaffen, mit der sich ein Zapfhahn der eingangs genannten Art auf einfache, montagefreundliche Weise nachrüsten und bei Bedarf an ein Zapfen mit CO2+ unter Überdruck anpassen läßt, so daß Bier und Schaum in einem angemessenen Verhältnis ausgegeben werden.The object of the invention is to provide a foam choke, with which a tap of the type mentioned in a simple, easy to install and retrofit can adapt to a pin with CO 2+ under pressure, so that beer and foam in an appropriate ratio be issued.
Die diese Aufgabe lösende Schaumdrossel besteht aus einer vor der Durchtrittsöffnung auf die Laufbuchse des Zapfhahns aufsetzbaren, die Durchtrittsöffnung überdeckenden Haube, die mit der Laufbuchse einen Labyrinthkanal einschließt, der einends zum Innern des Behälters hin offen ist und der andernends in die Durchtrittsöffnung mündet.The foam choke that accomplishes this task consists of a hood which can be placed in front of the passage opening on the bushing of the tap, which covers the passage opening and which encloses a labyrinth channel with the bushing, which at one end is open towards the interior of the container and which ends at the other end into the passage opening.
Bei einer bevorzugten Ausführungsform hat der Labyrinthkanal einen mäanderförmigen Verlauf.In a preferred embodiment, the labyrinth channel has a meandering course.
Bei einer bevorzugten Ausführungsform befindet sich das offene Ende des Labyrinthkanals nahe dem äußeren Ende der Laufbuchse. Das ist für die Restentleerung des Gebindes von Bedeutung. Der Zapfhahn ist dicht über dem Boden des Gebindes angeordnet, das zur Entnahme des Flüssigkeitsrests gekippt wird. Dabei muß sich ein Flüssigkeitspegel am offenen Ende des Labyrinthkanals einstellen.In a preferred embodiment, the open end of the labyrinth channel is near the outer end of the bushing. This is important for the emptying of the container. The tap is located just above the bottom of the container, which is tilted to remove the liquid residue. In this case, a liquid level must adjust at the open end of the labyrinth channel.
Der Labyrinthkanal kann sowohl auf dem Außenmantel der Laufbuchse, als auch auf dem Innenmantel der Haube ausgebildet sein. Bei letzterer Ausführungsform kann der Labyrinthkanal in einer Stichbohrung durch die Haube enden oder an einer Stirnseite der Haube auslaufen. In dieser Variante befindet sich die Öffnung des Labyrinthkanals noch näher am Ende der Laufbuchse.The labyrinth channel can be formed both on the outer jacket of the liner, as well as on the inner surface of the hood. In the latter embodiment, the labyrinth channel may end in a tap hole through the hood or leak at an end face of the hood. In this variant, the opening of the labyrinth channel is even closer to the end of the bushing.
Bei einer bevorzugten Ausführungsform läßt sich die Haube auf die Laufbuchse aufclipsen. Die Haube kann sowohl vollzylindrisch, als auch teilzylindrisch sein. In letzterer Variante hat die Haube einen Umschlingungswinkel von mehr 180°, vorzugsweise ca. 220°. Sie hält so unter leichter Spreizung durch Eigenelastizität an der Laufbuchse fest.In a preferred embodiment, the hood can be clipped onto the bushing. The hood can be both fully cylindrical, as well as partially cylindrical. In the latter variant, the hood has a wrap angle of more than 180 °, preferably about 220 °. It holds so under slight spread by inherent elasticity of the liner.
Bei einer bevorzugten Ausführungsform ist die Laufbuchse an ihrem Aussenmantel mit Rippen versehen. Die Haube der Schaumdrossel hat Ausnehmungen, die zwecks Positionierung über diese Rippen passen.In a preferred embodiment, the liner is provided with ribs on its outer shell. The hood of the foam choke has recesses that fit over these ribs for positioning.
