Definitions

  • keg systems developed.
  • the keg system is originally from England and builds on cylindrical Stainless steel drums with screwed riser on, designed for automatic cleaning and filling systems are.
  • the barrels have only one opening, into which the riser pipe, known as a sword, with the keg valve is screwed.
  • What is special about the keg system is that even the empty barrel is always closed to the outside world and it is constantly under carbon dioxide pressure. This means that beer residues or other contamination can practically not dry out. Almost sterile filling is also possible.
  • the relatively low weight also speaks for the keg barrel.
  • the keg system consists of a cylindrical outer part, the inside of the cylinder having a bayonet connection for attaching a filling system.
  • the upper edge of the outer part can be designed as a bead and, alternatively to the bayonet connection, can also be used to connect corresponding filling systems.
  • the sword which almost reaches the bottom of the barrel, directs the beer up through an opening to the tap system.
  • the top of the rapier can be closed by a closing element (plate or similar), which is normally closed by an appropriately adjusted spring.
  • a closing element plate or similar
  • part of the tap system is lowered onto this closing element by lever force, as a result of which the opening closed by the closing element is opened and the beer can flow into the tap system.
  • CO 2 overpressure connections for example for CO 2 cartridges, are also provided on the dispensing system, which can maintain sufficient pressure inside the beer keg as the internal pressure of the beer decreases as the tapping progresses.
  • the CO 2 pressure system is connected to openings in the keg closure which lead directly into the barrel area at the top of the barrel, that is to say are arranged separately from the rapier of the liquid surface of the beer.
  • the keg system is connected to beer kegs Dispensing systems significantly simplified.
  • Tap systems for keg connections only on designed the catering area and consist of numerous components made of metal. This leads to, that conventional tap systems for keg connections are expensive in the Purchase and complex maintenance (cleaning). So far, these restrictions have been limited to using Beer kegs with keg systems in the area of private beer consumption prevented. Breweries therefore need multiple beer keg systems run in parallel to meet all customers to be able to. On the one hand, this is complex, but on the other hand unsatisfactory for private customers, since they are not from the Benefits of the keg system can continue to benefit accept the operating problems of conventional dispensing systems have to.
  • the invention is based on the basic idea of implementation a complete tap system for keg connections only two main elements to use, which are linked together the mechanism can be locked in different positions of the keg system.
  • the keg connector according to the invention therefore consists only of two elements or assemblies, namely the connection element on the one hand, which is the one for mechanical connection with the necessary parts of the keg connection, and on the other hand from the tap, which is the flow of beer to a nozzle and, by means of a movement relative to the Connection element serves to open the keg closure.
  • the two elements are through the holding arrangement connected together.
  • the specific Design of the holding arrangement which is essentially only from a holding plate with an opening and a through it Holding arm exists, allows an overall very much simplified structure of the invention Dispensing systems compared to those known in the prior art Dispensing systems for the keg system.
  • the tap element can in brought a first relative position to the connecting element in which it is positioned so that when connecting of the connection element to the keg closure is in the way. Furthermore, the tapping element should never be one can make opening contact with the closing element, in order not to have a premature (i.e. before the safe connection of the connection element on the keg closure) To effect beer from the beer barrel. In the second relative position presses the valve element, which is on the tap element located on the closing element, and thereby achieves it Opening and the beer flow that through the beer line, which begins in the valve element, is led to the nozzle.
  • a Holding arrangement which is characterized is that the at least one holding arm has a holding projection has by engaging the at least one holding plate the connecting element and the tap element in the can lock second relative position to each other.
  • the holding arm takes the form of a hook, one The shoulder slides into the opening enables, and a projection area on the holding projection after sufficient pushing in through the opening can snap into place on the other side of the holding plate.
  • At least a holding arm has sufficient flexibility, to slide through the opening on the one hand, on the other hand to move when the holding projection slides through, that the retention tab is engaged with the retention plate can come.
  • the opening of the holding plate on its the holding projection opposite side leaves enough free space to the Holding projection by moving the at least one holding arm in the free space of the at least one holding plate to be able to solve.
  • the holding tab flexible and make the holding arm rigid. So the holding projection for example due to its intrinsic material elasticity or a built-in spring mechanism when sliding through Give in through the opening and after sliding through again snap forward to engage the retaining plate to kick.
  • the holding plate can both on the tap element and on the connection element be arranged, the holding arm then in each case is arranged on the other element.
  • the holding arm In the illustration is at least one holding plate on the tap element and at least a holding arm is arranged on the connection element.
  • Zapfsystems can already have a holding plate and a holding arm should be sufficient to match the system to stabilize and lock. It is for the sake of symmetrical force absorption however preferred that each two holding plates and two associated holding arms opposite each other are arranged on the tap system. Use too of three or more holding plates and corresponding holding arms is possible and can be useful. Can also be a holding plate can be combined with several holding arms, provided this holding plate has enough openings for the holding arms. So it is conceivable to use the holding plate as a ring surrounds the tap element, lay out and on the connection element provide a number of support arms which are in openings of the annular holding plate area engage.
  • connection element After connecting the connection element to the keg closure to initiate the tapping process, push the tapping element down towards the beer barrel in the second relative position to be brought.
  • at least one support for moving the Pin elements is arranged in the second relative position.
  • the support serves to support the hand holding the dispensing element should press into the second relative position, on the Post member.
  • the overlay can be used as a plate-shaped area or be designed as a handle, but it can also in the Special design of the top of the pin element exist.
  • the edition is part of the at least one holding plate is executed.
  • the holding plate can also serve as a support if it is sufficiently large to provide a support surface for the hand or part of the hand or hands of the user Offer.
  • the connection element has an annular region and the tap element at least with its valve part the annular region can be passed through in order to second relative position to be brought. So that surrounds it Connection element at least partially the tap element.
  • the tap system according to the invention can also be a safety arrangement have as a backup in the first Relative position of the connecting element and the tapping element prevents unwanted separation.
  • the second relative position is necessarily a locked position, in the two elements of the tap system are practical can not move relative to each other, so the safe To be able to guarantee beer flow would be without an additional one Fuse arrangement possible that the two Elements in the first relative position simply from each other separate.
  • the safety arrangement prevents this and ensures the mechanical integrity of the invention PTO system.
  • the safety arrangement can be carried out in this way be that after breaking the fuse a separation of the two elements is still possible, for example to make cleaning easier.
  • the securing arrangement can, for example, be a barb have on the connecting element or the tap element is arranged and in engagement with a holding projection can come, arranged on the other element is when the connecting element and the tapping element are in the first relative position.
  • a hook projection mechanism resembles that of the holding arrangement in use a holding projection for engagement in the holding plate.
  • the barb is preferably arranged on the holding arm and the retaining projection on the other element. To this Way, a particularly simple construction can be achieved, since barbs for securing arrangement and retaining tab for the holding arrangement in the same area, namely the holding arm can be arranged so that no additional Parts are needed.
  • the holding arm is preferably arranged on the connection element , it follows that the barb of the securing arrangement is arranged on the connection element or as an integral part of the holding arm for the connection element is attributable.
  • a recess may be provided on the tap element, which is a Retaining tab forms inside, in which the Barbs can engage.
  • Keg connection systems used in the catering sector have a pressure supply, for example using a CO 2 cartridge, which is intended to keep the internal pressure of a beer keg at a level necessary for the tapping process, even as the tapping process progresses.
  • a comparable system can also be installed in the tap system according to the invention.
  • the tap element further has a pressure connection for a gas supply and a gas line leading from the pressure connection through the tap element to the valve part.
  • the gas line must be routed in such a way that it opens into the beer barrel at a point that allows pressure to be exerted on the beer from above.
  • the gas line must therefore not end in the area of the closing element of the keg closure, since only the beer located in the riser pipe would be pressed down there, making tapping impossible.
  • a cartridge containing a CO 2 cartridge can be connected to the pressure connection.
  • the tap system has an air pump for generating an overpressure in the barrel, which is connected to the pressure connection. This air pump can then be used by the user to create an overpressure in the beer keg if he determines during the dispensing process that the internal pressure of the beer keg is no longer sufficient for a correct dispensing process.
  • the air pump can, for example, be one that e.g. has a cylindrical structure and on top the tap system can be connected so that Pressing down a lifting part of air pressed into the beer keg becomes.
  • Possibilities to build such a pump, which must also contain a check valve are one Specialist in the field of air pump technology.
  • the pressure connection can have a bayonet lock, in order to attach the air pump or one as simply as possible To enable carbon dioxide cartridge.
  • a screw cap can also be used be used or dispensing system and air pump are already firmly connected to one another during production, so that a separation is not possible for the end user is.
  • valve part must be designed so that it is on the one hand exert pressure on the closing element of the keg connector can, but on the other hand an influx of beer through the valve part to the nozzle is possible.
  • This can for example the valve part has a central bore, that is part of the beer line.
  • the keg system allows this in two different ways Attaching dispensing systems. This is the one on the inside Keg-lock lying bayonet connection, on the other hand the marginal bead on the outer part of the keg closure. On a tap system can be pushed onto these. Accordingly it is also possible to connect the connecting element of the invention To design dispensing systems differently. So it can be preferred that the connection element has a Keg-compliant bayonet connection for connecting the tap system to the keg connector. Because of the spatial cramped conditions this is usually the actually represent used embodiment.
  • connection element can also be used as a sliding connection for pushing the tap system onto an edge (Bead) of the keg closure.
