Definitions

  • the following invention relates to liquid containers such as beverage kegs, in particular beer kegs, with a dispensing attachment and a corresponding dispensing method.
  • Dispensing attachments for arrangement on beer vessels such as cans or barrels containing several liters of beer are known from the prior art, which make it possible to dispense beer by applying gas such as CO 2 to the contents of the barrel and providing such a carbon dioxide pressure that the beer is conveyed out of the container and is filled appealingly and tastefully with glasses with the appropriate foam crown.
  • the beer is then tapped via a tap, which is often arranged close to the floor on a vertical wall or on the pressure cap on the lid of the can or the barrel.
  • a pressure attachment of this type which can be placed on beverage cans in order to pressurize the beverage with gas by means of a carbon dioxide cartridge arranged in the pressure lid, is shown in FIG DE 10 2007 032 414 B4 described.
  • a pressure attachment which, in addition to the pressurization, also allows the beverage to be skipped, is included in DE 10 2009 041 115 A1 disclosed.
  • This hood-like pressure nozzle which can be placed on beer containers, comprises a gas supply pipe, called a sword, which extends from the pressure nozzle into the beer container, and further a CO 2 cartridge, which is in a fluidic manner via a valve arrangement with the gas supply pipe Connection is established.
  • the CO 2 cartridge is arranged in the hood and can be moved against an arbor by an actuating device, so that the arbor can penetrate a closure of the cartridge neck and can open a channel for the gas to escape from the cartridge, which can extend as far as a gas inlet opening of the gas supply pipe extends.
  • the pressure tap attachment has a telescopic outlet pipe which, at its end pointing into the hood, opens into a valve which can be opened by a lever arrangement and which can be fluidly connected to a riser duct which extends into the gas supply pipe.
  • the amount of carbon dioxide in the beverage can disadvantageously vary.
  • the content may be too high, so that the tapped beer foams excessively, while with increasing emptying of the beverage keg, the carbon dioxide content may decrease, so that the tapped beer then tastes stale.
  • US 534 541 A discloses a tap with an elongated tap pipe, which projects into the interior of the barrel with one end section.
  • a gas feed pipe which is movable in the longitudinal direction is integrated in the dispensing pipe.
  • An expansion device is attached to the end of the gas supply pipe, which, when the tap is arranged in the bung opening of the keg, points inside the keg, which can be inflated via the gas supply pipe so as to provide a pressure in the beverage keg that is desired for the tap.
  • the expansion device can be pulled into the elongated tap through the movable gas supply pipe.
  • a dispensing cap is arranged on a beverage bottle, and an expansion device, which surrounds a gas-carrying rod in a fluid-tight manner and gradually takes up the volume of the bottle when the beverage is removed from the bottle in a controlled manner.
  • AU 64787 80 A discloses a pump attachment for beverage containers, in particular bottles, which also has an expansion device protruding into the bottle, so that during a pump stroke, on the one hand air is conveyed into the expansion device and expanded, and on the other hand the amount of liquid corresponding to the pump stroke is conveyed out of the area.
  • WO 2013/074782 A1 shows a dispenser with which both air and wine can be removed from a wine bottle, the fluid flows into and out of the bottle can be regulated via several valve arrangements.
  • the system also implemented for wine storage and distribution US 2009/0095776 A1 comprises an inflatable bag as an expansion device and a device for providing a fluid channel along the bag in order to keep the transport path out of the bottle open when the bag expands.
  • An arrangement according to the invention comprising a beverage keg and a dispenser attachment is characterized in that the dispenser attachment is provided for arrangement on a beverage keg.
  • the dispenser and beverage keg are matched to one another in such a way that the dispenser can be placed on such a pre-determined keg when it is to be put into operation.
  • the dispensing attachment has a base body which has one or more fastening elements (s) with which it can be fastened on the beverage keg.
  • the fasteners can be detachable or non-detachable attachment of the nozzle.
  • the tap attachment has a connection device for a gas source and a first valve arrangement and a gas channel with an opening which, when the tap attachment sits on the beverage keg, points into the interior thereof.
  • the gas duct can be opened and closed, so that gas when connected to a gas source, precisely when the dispensing attachment is arranged in an operational arrangement on the beverage keg (i.e. readiness for dispensing consists), can be supplied from the gas source at a certain, preset pressure.
  • an actuating device is provided with which the valve arrangement can be actuated to open the gas channel.
  • the connection device can also be actuated in order to allow gas to flow, that is to say to release the fluidic connection to the gas source - this can be achieved with a separate actuation device or by coupling with the actuation device of the valve arrangement.
  • the dispensing attachment has a second valve arrangement and a riser duct with an opening, which, when the dispensing attachment is arranged in operation, points inside the beverage keg and an outlet provided by a dispensing tap.
  • the second valve arrangement which can be actuated with a further actuating device, opens and closes the connection between the riser and the outlet, so that when this actuating device is actuated, the beverage can be tapped from the barrel.
  • the dispensing attachment has a gas-tight expansion device which surrounds the gas channel at its mouth, so that gas supplied does not get into the beverage present in the beverage barrel, but into the expansion device.
  • the gas-tight expansion device can be converted from an unexpanded state into an expanded state by supplying gas from the gas source.
  • the expansion device is designed such that, in the expanded state and consequently in the operating arrangement, it has a volume which corresponds to at least an inner volume of the beverage keg on which the dispensing cap is placed. It is also conceivable that the expansion device in its fully expanded state can have a volume that is somewhat smaller than the internal volume of the beverage barrel, so that the expanded expansion device does not completely fill the inner volume of the barrel.
  • the expansion device should be designed such that in the expanded state it can have 100% of the interior volume of a predetermined beverage barrel or even more - the latter can of course only be fully developed outside the barrel. If such an expansion device is arranged in the barrel, it will of course not be able to take up a larger volume than the inner volume of the barrel. The oversizing only ensures that the expansion device can completely fill the inner volume of the barrel.
  • the dispensing attachment has a stabilization device which is formed by a rod which is present in or on the expansion device and stabilizes the latter when it is transferred from the unexpanded state to the expanded state.
  • the stabilization device is formed by the rod with an internal channel, so that a gas supply pipe is provided for supplying gas into the expansion device.
  • the gas supply pipe is attached so that the internal channel continues the gas channel.
  • a gas outlet opening can be located anywhere along the rod or tube, both at the very top, i.e. adjacent to the mouth of the gas channel, or at the distal end, so that the inner channel extends completely through the rod, or somewhere in between. More than one gas outlet opening can also be provided.
  • the rod thus extends from the base body of the nozzle way that he protrudes in the interior of the dispensing attachment according to the invention on the beverage barrel, preferably in or parallel to the longitudinal axis of the beverage barrel.
  • the beverage barrel has at least one spacer element which is attached to at least one inner wall of the beverage barrel, e.g. B. the inner surface of the jacket.
  • spacer elements can also be provided.
  • a spacer element provides a fluid channel on the wall of the barrel, so that even with the expansion device expanded to a very large extent, liquid can still reach the mouth of the barrel from the bottom of the barrel.
  • spacer elements which can be rod-shaped, tube-shaped or channel-shaped, for example, can also provide fluid channels on the barrel bottom and barrel top, so that fluid communication between the barrel bottom, inner surface of the beverage barrel and the barrel top can take place up to the mouth of the riser.
  • the spacer elements can be fastened to the barrel wall or inserted in the manner of a cage; the inside walls of the barrel can also be made with a profile; however, there may also be loose spacer elements in the barrel which lie against the wall with the expanding expansion device.
  • the tubes which extend from the dispensing attachment into the beverage keg are all used to remove the beverage, so that the beverage to be tapped rises through the beverage outlet tube, which partially extends to the bottom of the keg, according to the invention the beverage is discharged through the Press the riser with the mouth, which is located close to the tap, through the tap.
  • the tube, which extends through the container and is used to stabilize the expansion device, is provided for inflating the expansion device.
  • the length of the rod is adapted to that of the expansion device and corresponds at least to its length in its unexpanded state in order to be able to stabilize the expansion of the expansion device.
  • the expansion device arranged at the mouth of the gas channel thus also surrounds the rod or the gas feed pipe through which the gas is fed into the expansion device.
  • a suitable design of the stabilization device can prevent the displacement of the beverage from the barrel cover.
  • the expansion device With the gas outlet opening provided by the gas supply pipe at the lower end of the expansion device with an expansion device which has different areas with regard to its expandability, it can be achieved that the expansion device now initially expands near the ground, so that the beverage present in the barrel goes from bottom to top Is pushed towards the riser.
  • a stabilization device can consist of a plurality of rods which are connected to one another in an articulated manner and optionally with pretension to form a frame, similar to an umbrella rod. Such a linkage can also be at least partially attached to the wall of the expansion device.
  • the gas-tight expansion device can be formed by a balloon made of an elastic material which has a smaller surface area in the unexpanded state than in the expanded state.
  • the gas-tight expansion device can be a bag or bellows made of an inelastic or at least less elastic material than the balloon, such an expansion device being present in the unexpanded state and thus having only a small volume.
  • such an expansion device the surface of which does not differ significantly between the unexpanded and the expanded state, is unfolded by the supplied gas, in order to assume a correspondingly larger volume.
  • a preferred spacer element can be a channel device with a cross-sectional profile, which can be open U, V, C or W-shaped or a closed hollow profile.
  • the cross-sectional profile tapers from a lower opening in relation to the arrangement in the beverage keg to an upper opening, the wall thickness or the wall stability of the channel device increasing from the lower opening to the upper opening.
  • This channel device is arranged on the inner surface of the beverage keg and extends from the floor to the ceiling, so that the lower opening lies against the floor and the upper opening lies against the ceiling, the channel device having recesses or passage openings at both ends which have a fluid channel from the bottom of the beverage barrel through the channel device to the ceiling of the beverage barrel, even if the expansion device has already expanded far.
  • the channel device can be made of an elastically or plastically deformable material and so during expansion upon contact with the expansion device, first be pressed against the inner surface of the jacket in the area with thinner wall thickness / stability and then upwards. This change in shape only takes place when the expansion device fills the entire interior of the beverage barrel. This ensures that the fluid is finally pushed out of the channel device into the riser.
  • the tap attachment can have a suitable adapter.
  • Suitable adapters are, for example, flanges or fittings that can be detached - e.g. by means of a screw connection - or non-detachable, e.g. B. by welding or soldering, can be attached to the mouth of the gas channel and have one or more contact sections for gas-tight attachment of the expansion device. This can be done detachably or non-detachably, for example by means of gluing, welding, clipping or clamping.
  • the adapter can preferably be designed in such a way that the expansion device is detachably attached to the gas duct, so that virtually either the adapter or the expansion device are detachably attached, so that the expansion device can be easily detached for cleaning or replacement if the dispensing attachment is intended to be reused can.
  • the adapter can be used to attach the stabilization device.
  • the adapter can be used in particular to establish the glass flow, that is to say the fluid connection between the gas channel and the internal channel of the gas supply pipe.
  • a device for keeping the riser clear is arranged at the mouth of the riser.
  • This can be formed by a curved sieve device or a stepped basket device with side openings.
  • the curvature or the shoulder extends away from the riser, that is to say in the direction of the interior of the barrel, when the tap is arranged on a beverage barrel. This prevents the opening of the riser channel from being blocked by the expansion device in a partially expanded state before full expansion is reached. Even if the expansion device against the side of the screen or basket device facing the inside of the barrel bumps, the side openings remain free.
  • An alternative device for keeping the ascending channel free can be a crown device arranged around its mouth, which is formed by a plurality of wedge-like boundary walls that run radially towards the mouth, the height of which increases towards the mouth.
  • a device for keeping the riser clear can be part of the expansion device.
