Description

[0001] Arrangement for dispensing a beverage. Equipped with sensors and internal connection for further processing of the information.

[0002] The present invention relates to an arrangement for detecting the flow rate and / or the filling level of a beverage keg and / or the temperature of the beverage and / or the pressure of the pressurized gas line.

[0003] It is known from the state of the art to store beverages for consumption in containers. This allows for transport from the beverage production site, for example, a brewery, to the place of consumption, for example, a restaurant.

[0004] Common containers for beverages are bottles, cans, and kegs. In the latter case, it is possible to store larger quantities of the respective beverage,

[0005] REPLACEMENT LEAF (RULE 26) for example, to provide more than 10 liters, in particular more than 20 liters and preferably more than 30 liters of the beverage in a beverage keg.

[0006] In order to fill the beverage into the keg at the filling point and extract it at the tapping point, it is known that the beverage is dispensed from the keg under pressure with the aid of a gas. CO2 is used in particular for this purpose. The beverage kegs have a keg body with an outer shell. The keg body is usually made of a metallic material. The keg body usually has an opening in the middle of its top side into which a fitting is inserted. The fitting serves as a coupling point for filling the keg. Once the filling process is complete, the fitting remains on the keg and has a seal or sealing arrangement so that the beverage filled into the keg remains sealed and, if necessary, under pressure.

[0007] At the dispensing point, the beverage keg is connected to a dispensing system. There is a gas line for introducing the gas into the beverage keg and a beverage line for dispensing or extracting the beverage from the keg. For this purpose, a dispensing head is used, which is connected to the fitting, particularly in a form-fitting and fluid-tight, yet detachably connected manner.

[0008] Since the barrel body itself is usually made of a metallic, i.e., non-transparent and opaque material, and since the barrels are often cleaned after the initial filling and refilled dozens of times, it is necessary to obtain information about the respective barrel contents and, if necessary, additional information about the barrel and / or the fitting. Particularly due to the reuse of the fitting, external markings, such as stickers, labels, or even permanent markings, such as laser engraving, are only suitable to a limited extent.

[0009] For example, DE 10 2006 047 524 A1 and DE 199 48 471 C2 disclose a dispensing arrangement in which a central electronic unit is coupled wirelessly or by cable to a sensor.

[0010] REPLACEMENT LEAF (RULE 26) The present invention has the object of providing a possibility to improve the monitoring capability of a dispensing system or dispensing arrangement and thus to improve the ease of use and the quality of the beverages to be dispensed.

[0011] The above-mentioned object is achieved with the features in claim 1.

[0012] Advantageous embodiments are described in dependent patent claims.

[0013] The arrangement for detecting the flow rate and / or the fill level of at least one beverage keg in a dispensing arrangement comprises at least one sensor, wherein the sensor detects at least the "flow" state and / or the "no flow" state. According to the invention, it is characterized in that a central electronics unit is provided, which is wirelessly and / or wiredly coupled to the at least one sensor, wherein the sensor is arranged remotely from the electronics unit.

[0014] The electronics unit can also be described as a gateway. The electronics unit is a printed circuit board (also called a PCB) with corresponding chips, allowing at least raw data from sensors to be collected.

[0015] In its simplest form, a dispensing system is a dispensing system to which a beverage keg is connected. The beverage keg itself has a fitting onto which a dispensing head is attached, and a tap is connected to the dispensing head via a beverage line. However, the arrangement according to the invention is preferably used in larger establishments. These are, for example, restaurants where there are several taps in a serving area, with each tap connected to its own beverage keg. A gas can also be used to extract the respective beverage from the keg.

[0016] The goal is to monitor dispensing operations in real time. This allows for the fill levels of the respective beverage kegs, the temperature of the dispensed beverage, and, via conversion, the quantities of beverages dispensed or poured, as well as the respective gas pressure, to be recorded.

[0017] REPLACEMENT SHEET (RULE 26) The advantage of this is that it allows the user, i.e. the bartender, to monitor their connected beverage kegs in real time and, for example, to detect an impending keg change early on. They can also monitor the gas pressure of the respective compressed gas line for each tap head / keg, as well as the temperature of the respective beverages, and have an overview of the beverage quantities served. This provides the higher-level restaurant owner with a good opportunity to evaluate and control how many drinks are being served, allowing them to carry out logistical and business analyses, for example, regarding the stocking of beverage quantities, ordering of beverage quantities, and billing of beverage quantities.

[0018] A beverage supplier, or even a brewery, that is subordinate to the restaurant owner can also access data, for example, and thus conduct logistical and business analyses. By encrypting the data, this can be done anonymously, thus complying with the data protection regulations applicable in the respective country.

[0019] To ensure that the system is reliable and simple to design for on-site operation, the electronics unit initially only records the raw data. The raw data can then be transmitted to a cloud via the electronics unit. This ensures small data volumes due to the transmission of raw data. In particular, sensors can communicate wirelessly with the electronics unit, whereby the sensors and / or electronics unit can then be operated via an autonomous power supply, for example, batteries or accumulators. However, it is also possible to connect the electronics unit to a fixed power supply, particularly in the low-voltage range, for example, 5, 12, or 24 volts, to ensure operational reliability.Due to the small data size and preferably a triggered data query, for example not continuously but every few seconds, low energy consumption of the sensors and electronic unit is also guaranteed.

[0020] REPLACEMENT SHEET (RULE 26) The raw data is then particularly preferably imported into an evaluation unit remote from the electronics unit, for example a cloud storage or similar. This is where the raw data is converted into evaluation data, for example. Furthermore, the cloud storage can then be accessed via a display device. However, it is also conceivable for the conversion to take place in the gateway itself, using integrated software, and then the raw data is converted in the cloud for direct transmission to the display device. The display device can be, for example, a tablet or smartphone or other screen device that can be set up in the guest room of the restaurant and thus gives the user, i.e. the bartender, the ability to monitor the connected beverage kegs or the drinks being poured in real time, to signal an impending keg change, or similar.However, the display device can log into a cloud and thus also provide the information to the bartender. However, the data can also be read and visualized in a higher-level system center at the restaurant or brewery.

[0021] The sensors themselves are preferably at least one flow sensor, which is arranged, for example, in the dispensing head. However, the flow sensor can also be arranged in the dispensing nozzle itself. Preferably, at least one pressure sensor and / or a temperature sensor are also provided. The pressure sensor is preferably also arranged in the area of ​​the dispensing head, and the temperature sensor is preferably arranged in the area of ​​the dispensing nozzle.

[0022] The previously described sensors are then used to monitor a connected beverage keg. However, it is also possible to use multiple sensors and thus simultaneously use multiple beverage kegs, so that the previously described sensors—i.e., flow sensor, pressure sensor, and / or temperature sensor—are arranged per beverage line / installation.

[0023] For this purpose, it has proven particularly preferable for the electronic unit to monitor up to six dispensing arrangements. If more than six dispensing arrangements are present, it has again proven preferable for two electronic units to be connected in series, thus monitoring up to 12

[0024] REPLACEMENT SHEET (RULE 26) dispensing arrangements, or with three electronic units, up to 18 dispensing arrangements can be monitored. It is particularly preferred if the gateways are not connected to each other locally, but rather the data is then assigned to a shared operation / installation in the web app / cloud.

[0025] The electronics unit has a wireless receiver for communicating with the sensors wirelessly. This can be Wi-Fi, Bluetooth, or Bluetooth Low Energy (BLE), for example, although a radio connection, for example, in the 868 MHz range is preferred. This has proven to be particularly energy-efficient.

[0026] The electronics unit itself is then preferably connected via a wired structure, for example to the internet, in order to establish communication with, for example, a cloud. However, it has also been found that the electronics unit itself could preferably have a WiFi connection or a GSM connection, for example 4G or 5G, and thus provide data on an intranet or internet. This is particularly advantageous if the electronics unit is located, for example, in a drinks cellar that does not have a wired internet connection itself. The electronics unit can thus connect via a router located in the house, which in turn establishes the connection to the internet.In cases of poor GSM coverage, an antenna connector on the gateway can be used to connect an external antenna directly or to route it outside a building or room via a cable. From there, the GSM connection can then be used.

[0027] The electronic unit itself is splash-proof and moisture-proof.

[0028] Furthermore, a display device can be present on the electronics unit, in the simplest case LED or LCD displays, to signal the status of the sensors.

[0029] Especially if the beverage keg is provided with a data record, for example via a data carrier, also called a tag or NFC TAG in the fitting

[0030] REPLACEMENT SHEET (RULE 26) data can also be provided on the brand of the contents, i.e. on the beverage and manufacturer of the contents of the struck beverage keg.

[0031] With this information, the web app can then automatically set the connected beverage brand and keg volume, compare it with the best-before date, and link the tag's ID to the dispensed volume. Thus, if the same ID is detected within a defined short period of a few days, an opened keg can be identified with the individual fill level upon reconnection.

[0032] Preferably, the dispenser head also has a reading unit, such as an antenna, to read this data. The data can then be forwarded to the electronic unit or gateway described here via sensors or electronics in / on the dispenser head.

[0033] Furthermore, thanks to the available raw data, the WebApp can suppress an update of the measured temperature on the dashboard if the dispensed volume / duration was not large or long enough to overcome the natural inertia of the temperature sensor.

[0034] Furthermore, maintenance times and maintenance intervals of the beverage lines can be both displayed and documented so that hygiene regulations and manufacturer specifications are met.

[0035] It would also be conceivable for the electronics unit to directly convert the raw data using an additional chip unit and then process and transmit the information either via an LCD display or a dedicated connection to a display device, such as Bluetooth or Wi-Fi. However, this would increase the energy consumption of the electronics unit itself. However, the results converted in the gateway are preferably also transmitted to the cloud for the web app.

[0036] The electronic unit can in particular be arranged in a splash-proof plastic housing and then has plug connections in order to

[0037] REPLACEMENT SHEET (RULE 26) various sensors, power supply, antenna(s) or a display or a serial gateway connection.

[0038] Further advantages, features, properties, and aspects of the present invention are the subject of the following description. Preferred embodiments are the subject of the following description. These serve to facilitate understanding of the invention. They show:

[0039] Figure 1a Arrangement for detecting the flow rate and the fill level of a beverage barrel,

[0040] Figure 2a Electronics unit in detailed view.

[0041] In the figures, the same reference symbols are used for identical or similar components, even if a repeated description is omitted for reasons of simplification.

[0042] Figure 1a shows an arrangement 1 for recording the flow rate and fill level of a beverage keg 2. Four beverage kegs 2 are shown for this purpose. A dispensing head 3 is mounted on each beverage keg 2. The beverage kegs 2 are connected to gas bottles 4 via the dispensing head 3. Furthermore, a beverage line 5 leads from each dispensing head 3. These beverage lines 5 are led to a respective tap 6. A beverage can then be dispensed from the tap 6, for example into a glass 7. A central electronics unit 8 is provided. The electronics unit 8 is connected by cable 9 to at least one sensor in the dispensing head 3. This sensor can, for example, record the flow or non-flow of the dispensed amount of beverage. Using any stored information that a keg change has taken place, the fill level can then be calculated back.

[0043] Furthermore, the central electronic unit 8 also has a wireless communication 10 or wireless communication module via another sensor, for example a temperature sensor 12. Each tap 6 is assigned a temperature sensor 12, which in turn can communicate with the electronic unit 6 via a wireless communication 10. The electronic unit 6 itself can, for example,

[0044] REPLACEMENT SHEET (RULE 26) communicate with a cloud 16 via a wired connection via the internet 13, but also via WLAN 14 or a GSM module 15. The raw data from the sensors can then be analyzed or converted in the cloud 16. Various data can then be read out via various display devices, such as a smartphone 17, computer 18, laptop, or tablet 19, such as the fill level of the beverage keg 2, the brand and manufacturer of the beverage contained in each beverage keg 2, the temperature of the tapped beverage, and the gas pressure of the respective pressurized gas line. Furthermore, conclusions can be drawn about upcoming cleanings of the beverage lines, or these cleaning processes can also be documented.The display devices can be read, for example, by a user, a bartender who is also operating tap 6, but also by a restaurateur who also operates multiple restaurants, such as a chain restaurant, or even by a brewery that oversees this restaurant, which in turn can evaluate the data. Various security clearances can exist, allowing data to be read anonymously in order to comply with the respective data protection regulations of each country.

[0045] Figure 2a shows a detailed view of an electronics unit 8. The electronics unit 8 can, for example, have a plastic housing 20, and a printed circuit board or PCB board 21 is arranged in the plastic housing 20 itself. Wireless communication units 10, for example Bluetooth or WLAN 14, can in turn be arranged on the PCB board 21 itself. Furthermore, a power connection 22 can be provided, for example, for an external power supply, for example in the low-voltage range. Furthermore, a bus line 23 can be arranged, making it possible to connect several electronic units 8 in series. Each electronics unit 8 preferably has, as shown here, six wired connections 24 for connecting sensors. Furthermore, the electronics unit 8 has a GSM antenna 15 to enable wireless communication with a cloud 16, i.e., without the Internet 13 or an Ethernet connection.

[0046] Some or all features of this invention may be combined with some or all features of the inventions listed below.

[0047] REPLACEMENT LEAF (RULE 26) The present invention further relates to a dispensing head arrangement for connection to a beverage keg according to the features in the preamble of patent claim 6.

[0048] The present invention also relates to a method for determining the filling state of a beverage keg.

[0049] It is well known from the state of the art to provide beverages in kegs, especially in restaurants. Common keg sizes are 10 liters, 20 liters, 25 liters, and 30 liters, as well as 50 liters. The kegs are delivered by a logistics company and are usually stored in an out-of-sight area away from the bar or dispensing point. This area usually needs to be refrigerated so that the beverage can be provided chilled. Kegs are often stored in a beverage cellar.

[0050] There is a need to know the fill level of each tapped beverage keg, especially when different kegs containing different beverages are tapped at a dispensing system.

[0051] This knowledge is essential in three respects. Especially during peak times, a keg change can take several minutes, which a single bartender, a single person operating a dispensing system, cannot afford to spare.

[0052] A second need is to know the current fill level in order to be able to order the quantities of drinks required for the next days or weeks in an ordering process.

[0053] A third possibility is to use the respective fill level tables to ultimately record the respective withdrawal quantities from a particular beverage barrel over a particular period of time.

[0054] Various inline measuring systems are known from the prior art; for example, a measuring arrangement is known from DE 20 207 334 U1. This involves a flow meter that allows a control unit to read or reset the meter reading and thus determine the amount of beverage dispensed for specific periods. The disadvantage of this is that a

[0055] REPLACEMENT SHEET (RULE 26) Such a flow sensor is operated, for example, via a vane wheel. The vane wheel engages directly with the beverage line. However, the beverage lines must be cleaned regularly, sometimes using so-called cleaning beads. Measuring systems that engage with the beverage line are therefore disadvantageous and require special cleaning.

[0056] The object of the present invention is therefore to provide a possibility that requires as little maintenance and is as error-free as possible in order to enable level monitoring and content information of the tapped or tapped beverage kegs with minimal use of measuring technology.

[0057] The above-mentioned object is achieved according to the invention in the arrangement for detecting the flow rate and / or the filling state of a beverage keg with the features in claim 6.

[0058] Advantageous embodiments of the present invention are described in the dependent claims.

[0059] The arrangement for detecting the flow rate and / or fill level of a beverage keg comprises at least one dispensing head and one beverage keg. The dispensing head is connected or attached to the beverage keg. A sensor is assigned to the dispensing head, with the sensor detecting at least the "flow" or "no flow" state.

[0060] The sensor itself is either integrated directly into the dispensing head or attached to the dispensing head.

[0061] According to the invention, the sensor detects the "flow" or "no flow" state. With the help of a stored database, which consists either of an algorithm and / or a stored table, a conclusion can be drawn about the amount of beverage flowing through the dispensing head or line based on the time during which flow is detected. This, in turn, can be used to calculate the remaining fill level of the beverage keg. For this purpose, the flow rate, e.g., in liters per minute, is preferably stored in the system at each measuring / dispensing point. This happens

[0062] REPLACEMENT SHEET (RULE 26) preferably by calibration / measurement by the system operator, e.g. by measuring the time during the dispensing of a specific and known amount of beverage. Alternatively, a learning program can be implemented in the electronics software so that after startup the times of all dispensing processes are added up and the operator can then simply enter the total amount dispensed. This in turn calculates the flow rate in liters per minute. With fixed control variables this is usually constant for each beverage line / installation. The flow rate only needs to be recalculated if changes are made to the installation by the operator (e.g. the delivery pressure or the compensator on the tap). This can also be done by adding up all the times for the complete dispensing of an entire keg.Since the operator already selects the keg change in the software by selecting the newly tapped volume, this is also possible semi-automatically. Alternatively, the volume of the tapped beverage can be entered into the web app for the last recorded measurement for calibration purposes.

[0063] If, for example, the system is set to a flow rate of 2.5 l / min and the tapping process takes 12 seconds, it can be converted that a volume of 0.5 liters has been withdrawn, which is subtracted from the total fill level of the keg.

[0064] The present invention has many advantages over variants known from the prior art. Firstly, only a minimal use of sensor technology is required, which is therefore cost-effective, simple, and resistant to failure. Because the data is recorded and processed, it is stored, in particular, on an external server or in a cloud and can therefore be retrieved. This allows the operator of the dispensing system to retrieve the individual fill level of one or more beverage kegs at any time, providing advance warning of a keg change. A forecast can also be created for ordering future beverage kegs, since the withdrawal quantities are logged over time.

[0065] In a particularly preferred embodiment, the sensor is integrated directly into the dispensing head. The sensor is designed, in particular, as a reed sensor or reed switch.

[0066] REPLACEMENT LEAF (RULE 26) or reed contact and / or capacitive sensor and / or inductive sensor. A tappet plunger is located in the tappet. Within the tappet plunger, in turn, there is usually a non-return valve. This non-return valve is designed, for example, as a magnetic bar or ball, particularly made of a metallic material. It can thus be used to switch a magnetic contact and thus detect the "flow" or "no flow" state.

[0067] According to the invention, a first sensor is thus designed such that a signaling element, in particular a magnetic rod or ball, but in other configurations, is integrated into the beverage line. This signaling element is moved to a different position as the beverage flows, in particular raised relative to the vertical direction. The signaling element thereby assumes the position of a sensor, in particular a reed sensor, which thus detects the "flow" state of beverages or fluid in the beverage line. The signaling element can be cleaned together with the dispensing head or simply removed for cleaning and then reinserted. Furthermore, such backflow preventers on dispensing heads are known.

[0068] For this purpose, the dispensing head itself can, in particular, be made of a plastic material. Such a dispensing head is known, for example, from EP 2 730 537 A2, the entire disclosure of which is incorporated herein.

[0069] In some applications, it may happen that a tap head is not stored vertically, for example, when changing kegs, but horizontally. This can inadvertently trigger the "flow" contact. To prevent this, a second sensor is preferably installed to detect that the tap head is properly attached to the keg and locked. This can be achieved, for example, by a second sensor that detects that the tap head lock is lowered and thus recognizes that the tap head is struck on the keg. This can also be achieved via a reed contact. Only when the sensor detects that the tap head is struck on the keg does the actual first sensor detect the "flow" state.

[0070] REPLACEMENT SHEET (RULE 26) Furthermore, an inductive or capacitive sensor is conceivable, positioned in the dispensing head in such a way that it detects the metal fitting of the beverage keg as soon as the dispensing head is tapped. In a preferred design variant, the flow signal from the dispensing head is validated in the electronics or the web app with the flow signal from the dispensing tap.

[0071] Additionally or alternatively, a pressure sensor is provided in the dispensing head. The pressure sensor and / or capacitive sensor and / or inductive sensor is designed, in particular, as a plug-in sensor. The pressure sensor is thus sealed fluid-tight and / or gas-tight, for example, with an O-ring. The plug-in connection allows the wired sensor to rotate completely around its own axis.

[0072] In a preferred embodiment, it is also possible to determine a flow rate using two pressure sensors connected in series in the axial direction according to the Venturi principle.

[0073] The pressure sensor can be located in the dispensing head, preferably in the gas line. To determine the flow rate, two pressure sensors can be arranged in series in the gas line. If pressurized gas is introduced into the gas, this automatically means that extraction is taking place elsewhere. In the case of a flow meter, which consists of two pressure sensors, these can also be located in the beverage line of the dispensing head.

[0074] Particularly preferred is an electronics unit assigned to the dispensing head, arranged directly on the dispensing head, or integrated into the dispensing head. Especially if the dispensing head is made of a plastic material, an electronic circuit board can be arranged directly on the dispensing head. The wiring of the pressure sensor and the reed sensor can then be connected directly to the electronics unit. The electronics unit can be connected to a higher-level evaluation unit either via a cable connection or via wireless communication with a higher-level evaluation unit.

[0075] In a further, particularly preferred or supplementary embodiment, the dispensing head has an antenna for reading information. This is

[0076] REPLACEMENT SHEET (RULE 26) particularly integrated at the bottom or foot of the dispensing head. In particular, this antenna is designed as an NFC antenna or RFID in any frequency range. This makes it possible to read information present on a keg or, in particular, a fitting of a keg, and here in turn preferably on a data carrier in a fitting of a keg. For example, such a data carrier of the fitting, which in turn is designed as an NFC or RFID in any frequency range, can store data on the filling date, contents, and type of beverage in the keg. This data could then be read by the dispensing head's antenna and transmitted to the electronics unit, which in turn is transmitted to a higher-level evaluation unit. The electronics unit and the antenna are capable of reading and processing various NFC standards, such as ISO 14443 and ISO 15693.

[0077] The system is preferably designed in such a way that an electronic unit or an electronic evaluation system is present. This is particularly preferably connected via cable to the sensors in the dispensing heads. The sensors in the dispensing heads then transmit the "flow" or "no flow" signal to the electronic evaluation unit. The electronic evaluation unit can then directly calculate the flow rate, particularly based on the time window in which the sensor reports "flow." If necessary, an additional temperature sensor in the dispensing tap can also be used to prevent incorrect measurements when the dispensing head is in the horizontal position, validating the flow measurement by measuring the temperature drop as the beverage flows through. A pressure sensor on the so-called gas pressure reducer of the dispensing system can provide the same result, as the expected pressure drop validates the flow measurement.However, the electronic evaluation unit can also only record the raw data.

[0078] The raw data and / or the calculated flow rates are then preferably transferred to an external database. This is usually a cloud-based database. The required data can then be retrieved from the cloud, for example, via a mobile device, particularly a tablet or smartphone. This can be located at the pub itself or near the dispensing system, so that the dispensing system operator is informed about the

[0079] REPLACEMENT SHEET (RULE 26) the current fill level of a beverage keg. However, in the case of a larger catering chain with several geographically separated branches or similar, the data can also be forwarded to a central evaluation center, allowing a central ordering process to be carried out from there. Furthermore, the collected data is very useful for marketing purposes, for example, by breweries, because it allows them to see which brands are being served well or poorly at which locations and at what times.

[0080] Particularly preferably, an algorithm and / or data table or data matrix can be stored in the evaluation unit. The "flow" or "no flow" signal, as well as the respective time window, can then be readjusted if the measured values ​​deviate from the actual values. This can be the case, for example, if an existing dispensing infrastructure allows for a higher or lower flow, necessitating a respective readjustment.

[0081] In particular, the system can also be designed to be self-learning. By specifying or entering the respective fill volume of a beverage keg in the data matrix, a self-learning process can then take place. For example, when connecting any keg, the flow rate is determined by recording and summing all flow times. This is because the system assumes a nearly completely empty keg during each keg change and then correlates the measured dispensed beverage volume with the actual keg change, i.e., the consumed keg.

[0082] The sensors in the dispensing heads are typically connected to the electronic evaluation unit via a cable. However, wireless data transmission is also possible. A cable connection, however, allows the electronic evaluation unit to be centrally connected to a permanent power supply, such as an existing power grid. This, in turn, supplies the sensors in the dispensing heads with power. The sensors, preferably the NFC antenna, do not have to be connected to the electronic unit via a cable, but can also be connected to the electronic unit via a pluggable or detachable connection (pin and socket).

[0083] REPLACEMENT SHEET (RULE 26) Furthermore, the cable connection from the electronics unit to the evaluation unit (gateway) can be implemented by means of a cable as an integral part of the electronics unit, but preferably the electronics unit has a commercially available plug connection for data transmission so that any cable length can be connected.

[0084] The data can be transmitted wirelessly from the evaluation unit, for example, via a Wi-Fi or GSM connection, eliminating the need for a data line to another external evaluation unit or the cloud. A wired internet connection (Ethernet) is also conceivable.

[0085] The present invention thus also relates to a method for operating the above-described arrangement. In particular, the method can be used to determine the flow rate and / or the fill level of the beverage keg.

[0086] For this purpose, the process is operated in such a way that, with the help of the previously described sensors, it is detected whether a beverage is being drawn from a respective beverage keg, thus establishing a "flow" or "no flow." Using a stored database, which can be an algorithm or a database table, the drawn volume from the beverage keg is calculated based on the time window for which the sensor sends a message indicating flow. This, in turn, can be used to determine or calculate the remaining fill level of the beverage keg.

[0087] Further advantages, features, and aspects of the present invention are the subject of the following description. Preferred embodiments are illustrated in schematic figures. These serve to facilitate understanding of the invention. They show:

[0098] Figure 1b shows an arrangement 1 according to the invention for detecting the flow rate and / or the fill level of a beverage keg 2. For this purpose, a dispensing head 3 is arranged on the keg 2 and a sensor (not shown in detail) is integrated into the dispensing head 3. The dispensing head 3 is connected to a tap 5 via a beverage line 4. The beverage keg 2 is located, here shown, in a cellar 6 of a building 7. The tap 5 is located in a bar area 8. The cellar 6 and the bar area 8 can then be separated from one another by a floor 9. It is now desirable for the operator of the tap 5 to be aware of the respective individual fill level 10 or the fill level 10 of the beverage keg 2 shown. Several beverage kegs 2 can be arranged in order to provide different beverages at different taps 5, although this is no longer shown here.The sensor of the dispensing head 3 is now connected to an electronic evaluation unit 12. This can be done wirelessly as shown, but can also be wired 11. The electronic evaluation unit 12 preferably communicates via wireless signal with an external database, shown here in the form of a cloud 14. Either only raw data is transmitted, so that the fill level 10 is calculated using an algorithm of a web-based program within the cloud 14. However, the calculation can also already be performed in the electronic evaluation unit 12. From there or from the cloud 14, a terminal 15,

[0099] REPLACEMENT SHEET (RULE 26) For example, the fill level 10 can be queried or displayed using a tablet, PDA, or smartphone. This then provides the necessary information for further organizational processes, such as reordering drinks or the imminent need for a keg change. The keg change is then entered by the operator either on the unit 12 or via a terminal device 15 if the version with the NFC antenna is not available and a keg with a tag can be read. For example, an alarm signal can also be given when a keg change is imminent or when the temperature sensor on the tap 5 or the pressure sensor on the pressure reducer detects a deviation. During peak times in the tap room 8, it can thus be ensured that all guests are supplied with drinks without major downtimes.

[0100] The described advantage is that the measuring technology can be reduced to a minimum, so that the cleaning of beverage line 4 and the provision of food-compliant measuring technology is also optimized.

[0101] A preferred embodiment is shown in Figures 2b and 3b. Here, a dispensing head 3 is shown, which is shown in the attached and locked state in Figure 2b, and in the open state in Figure 3b. The dispensing head 3 itself has a lever 16. If the lever 16 is pressed down and locked, a dispensing head plunger 17 is retracted axially towards the plane of the image downwards into a fitting (not shown in detail) of a beverage keg 2. The beverage can then be directed in the direction of arrow 18 through the beverage line 4 towards the dispensing tap 5 (not shown in detail). For this purpose, a non-return valve, in particular designed as a magnetic rod 19, or a magnetic rod 19 with a food-compliant sheath, is arranged in the dispensing head plunger 17. The magnetic rod 19 is moved upwards in the axial direction, in particular due to the fluid flowing through. A sensor 20, here in the form of a reed sensor 20, is arranged in or on the dispensing head 3.This detects the position of the magnetic rod 19 and can thus emit the sensor signal "flow." In Figure 3b, the magnetic rod 19 is positioned downwards in the vertical direction and not near the reed sensor 20. This generates the signal "no flow." Optionally, the sensor can be connected via

[0102] REPLACEMENT LEAF (RULE 26) a sensor, not shown in detail, which is arranged in the area of ​​the lever 16 or detects the lever position, nor can it be ensured that, for example, a horizontal storage of the dispensing head 3 and thus an accidental upward sliding of the magnetic rod 19 still emits the signal "no flow", since in this state, for example when changing the keg, no flow of fluid occurs.

[0103] Figure 4b shows the dispensing head with a pressure sensor 21, which is arranged in a gas line 22 or the dispensing head 3 contained in the gas tap. The pressure sensor 21 is coupled via a cable 23 to an electronics unit 24 arranged on the dispensing head 3. Furthermore, the reed sensor 20 is also connected to the electronics unit 24 via a connecting cable, and the antenna 26, which is described further in the following figures, is also coupled to the electronics unit 24. The electronics unit 24 can be directly integrated into the dispensing head, particularly in the case of a plastic material dispensing head. For example, a closable cover can then simply be clipped onto the electronics unit 24, or preferably, the electronics are encapsulated in resin after assembly to protect them.

[0104] Also shown are two spring tongues 27. The spring tongues 27 allow a gas adapter 28 to be attached to the dispensing head in axial direction A. Furthermore, locking hooks 29 for receiving the pressure sensor 21 are arranged on the gas adapter 28. A screw thread for attaching a receptacle for the pressure sensor 21 of a gas adapter 28 can be omitted. This allows for easier handling.

[0105] Figures 5b and 6b illustrate this again. In Figure 5b, a gas adapter 28 is inserted over the spring tongues 27 on the gas side. To do this, the gas adapter 28 can simply be inserted in axial direction A and locked into place. It is then sealed gas-tight by an O-ring 30.

[0106] Figure 6b shows a pressure sensor 21. This is inserted into the gas adapter 28. For this purpose, locking hooks 28 are arranged and the pressure sensor 21 is sealed by a further O-ring 30. The cable 23 of the pressure sensor 21 can thus rotate about its own axis, so that installation is simplified and does not require a

[0107] REPLACEMENT SHEET (RULE 26) Pressure sensor 21 via a thread would cause a corresponding twisting of the cable.

[0108] Figures 7ab and bb show a further advantageous embodiment of the invention. Here, an antenna 26 is integrated into the tap head 2 in the area of ​​the underside of the tap head. The antenna 26 serves to read data arranged on the data carrier of a fitting (not shown in detail) or a keg. The antenna 26 is connected to the electronics unit. This allows the data from the keg's data carrier and / or the data from the fitting's data carrier to be read out, for example, the filling location, filling date, contents of the keg or keg volume, and the type of beverage contained in the keg. Figure 7bb shows a detailed sectional view of Figure 7ab.

[0109] Figures 8ab and 8bb show an alternative design variant. Here, the antenna 26 is inserted, for example, as a circumferential partial circle into a circumferential groove 31 at the bottom of the dispensing head 3, in the case of Figure 8ab. Figure 8bb shows an exploded view.

[0110] Figures 9ab and 9bb show further alternative design variants. Here, the antenna 26 is inserted not on the underside of the dispensing head 3, but in a central area, as shown in Figure 9ab. Figure 9bb, which is an exploded view, shows the antenna being pulled out of a corresponding groove and is shown in plan view. The antenna 26 is not circular or ring-shaped, but rather U-shaped, for example, so the antenna can be inserted from the side.

[0111] Some or all features of this invention may be combined with some or all features of the inventions listed above and / or listed below.

[0112] REPLACEMENT LEAF (RULE 26) The present invention further relates to a tap assembly for a dispensing system for connection to a beverage keg according to the features in the preamble of claim 16.

[0113] It is known from the state of the art to store beverages for consumption in containers. This allows for transport from the beverage production site, for example, a brewery, to the place of consumption, for example, a restaurant.

[0114] Common containers for beverages are bottles, cans, and kegs. In the latter case, it is possible to provide larger quantities of the respective beverage, for example, more than 10 liters, especially more than 20 liters, and preferably more than 30 liters of the beverage in a keg.

[0115] In order to fill the beverage into the keg at the filling point and extract it at the tapping point, it is known that the beverage is dispensed from the keg under pressure with the aid of a gas. CO2 is used in particular for this purpose. The beverage kegs have a keg body with an outer shell. The keg body is usually made of a metallic material. The keg body usually has an opening in the middle of its top side into which a fitting is inserted. The fitting serves as a coupling point for filling the keg. Once the filling process is complete, the fitting remains on the keg and has a seal or sealing arrangement so that the beverage filled into the keg remains sealed and, if necessary, under pressure.

[0116] At the dispensing point, the beverage keg is connected to a dispensing system. There is a gas line for introducing the gas into the beverage keg and a beverage line for dispensing or extracting the beverage from the keg. For this purpose, a dispensing head is used, which is connected to the fitting, particularly in a form-fitting and fluid-tight, yet detachably connected manner.

[0117] In the tap arrangement, a beverage keg is transported to a location, for example, a cold storage facility or a drinks cellar of a restaurant, and is connected to a dispensing system. The beverage can then be extracted from the tapped keg at a tap. For this purpose, a tap usually has

[0118] REPLACEMENT SHEET (RULE 26) has a pivoting lever. This pivoting lever is used to open and close the flow of the beverage. In the most common and simplest design, the pivoting lever can be pivoted between the "closed" position (no flow) and the "open" position (fully open to the flow of the beverage). The beverage is then extracted from the keg via a beverage line and flows through the tap into a container, such as a glass or pitcher.

[0119] To ensure that the beverage flows from the tap into the container, the tap is equipped with a spout. The spout is a tubular piece or piece of pipe. This is essentially oriented vertically. The spout itself can be slightly curved and does not have to have the same diameter across its entire length; the diameter can also vary slightly.

[0120] From US 2009 / 0248643 A1 a tap arrangement is known in which a temperature sensor for measuring the beverage liquid can be arranged in the tap.

[0121] The object of the present invention is, based on the prior art, to obtain more precise data on the beverage to be dispensed or on the tapped beverage keg during the operation of a dispensing system and / or during the dispensing of a beverage.

[0122] The above-mentioned object is achieved according to the invention with the features in claim 16.

[0123] Advantageous embodiments are described in the dependent claims.

[0124] The tap assembly according to the invention is intended for a dispensing system for connection to a beverage keg. The tap has a pivoting lever for adjusting the flow of a beverage through the tap and an outlet spout from which the beverage flows into a container.

[0125] REPLACEMENT SHEET (RULE 26) A valve is provided that opens or closes a beverage line running through the tap, and optionally partially opens it. The tap is connected to a dispensing head via the described beverage line. A beverage keg is attached to the dispensing head. The beverage line can be several meters long, so that it runs, for example, across a single floor in a restaurant, from the ground floor to a beverage cellar, or from a dispensing point to a cold storage facility.

[0126] According to the invention, the tap assembly is now characterized in that at least one sensor is arranged in the outlet spout for determining the temperature and / or the flow rate of the beverage to be tapped.

[0127] The temperature is preferably measured using a temperature sensor and output as an electrical signal, which can later be converted into any temperature unit, e.g., degrees Celsius or Fahrenheit.

[0128] The flow rate is preferably measured in accordance with the invention in such a way that flow occurs or not, and the sensor in the outlet spout therefore detects whether the tap is open or closed.

[0129] For this purpose, a customer-specific evaluation electronics unit is assigned to the tap. Optionally, a wireless communication unit is also assigned to the tap. The wireless communication unit or customer-specific evaluation electronics is located directly on the tap or integrated into the tap. Preferably, the electronics unit is only connected to the outlet pipe and can be completely removed from the tap itself along with the outlet pipe. The preferred location for the batteries is on or at the bottom of the housing to allow for easy battery replacement while the housing is or remains installed on the tap.

[0130] A housing is provided. This housing is made, in particular, of a plastic material. The housing at least partially surrounds the tap. This makes it possible to retrofit existing taps in installations with the solution according to the invention. The outlet spout is designed to be removable from a tap, in particular for cleaning purposes.

[0131] REPLACEMENT SHEET (RULE 26) The outlet spout can be replaced with an outlet spout with a sensor according to the invention. According to the invention, the outlet spout is integrated into the housing, in particular detachably integrated, so that the outlet spout is replaceable for cleaning or maintenance purposes, or even for repair purposes. However, because the outlet spout is integrated into the housing, the sensor or multiple sensors are directly connected to a customer-specific evaluation electronics and / or wireless communication unit via a cable in the housing.

[0132] Particularly preferably, a power source, such as a rechargeable battery or batteries, is arranged in the housing. However, the housing can also be powered via an external power connection. A low-voltage power source is preferably used here to ensure operational safety.

[0133] The flow rate is particularly preferably measured by a sensor which is integrated into the spout. This sensor is designed in particular such that two opposing contact elements are arranged in the spout. The contact elements are arranged at the same height in particular in the axial direction or longitudinal direction of the spout, but are radially spaced apart, in particular on opposite sides. If a beverage is now dispensed through the spout, the liquid in the beverage itself is electrically conductive. The two opposing contacts of the sensor are thus electrically connected to one another and determine that a flow rate is taking place. Another option for checking the flow rate is to network the sensors by using only one contact of the first sensor and another contact of the second sensor. The flow rate can be measured, for example, using a resistance value to be measured.via a conductivity that results. This eliminates the possibility that residual moisture, for example, on the inner surface of the outlet spout, would still measure flow, even though only a film remains on the inner surface, and in reality, no flow through the outlet spout occurs.

[0134] In a particularly preferred embodiment variant, it is further provided that a second sensor for determining the flow is arranged downstream of a first sensor for determining the flow in the longitudinal direction of the outlet spout,

[0135] REPLACEMENT BLADE (RULE 26) so that the two sensors are spaced apart longitudinally. This makes it possible for a time delay to occur between the beverage passing the first sensor and the second sensor when multiple measurements are taken or multiple sensor signals are generated. The respective flow time and flow rate can be used to determine the fill level of the keg or the amount of beverage dispensed through the spout. For example, the sensor system according to the invention can be combined with a higher-level processing unit, which can also be part of the installation, with the processing unit storing the time when a new keg is tapped.

[0136] This allows for inventory control and consumption measurement of various tapped beverages, for example, in a restaurant. Furthermore, it enables quality control, which determines the temperature at which each beverage is dispensed and thus reaches the guest, which in turn provides the guest with information about the quality of the tapped beverage.

[0137] The present invention thus also relates to a method for operating the tap arrangement with outlet spout according to the invention.

[0138] Furthermore, a visual indicator or display is preferably arranged on the housing, particularly on the front. The display makes it possible to provide the tap operator with various data in real time. For example, the temperature of the tapped beverage can be displayed. Furthermore, it is possible to display the fill level of the keg or, when a certain remaining amount of the keg is reached, to emit a warning signal, such as a red LED. This allows the tap operator to more easily determine when to change kegs, especially during peak beverage dispensing times, and to avoid the dispensing system running dry in case of doubt.

[0139] Further advantages, features, properties, and aspects of the present invention are the subject of the following description. Preferred embodiments are the subject of the following description. These serve to facilitate understanding of the invention. They show:

[0140] Figure 1 c is a perspective view of a tap arrangement;

[0145] Figure 6c is a longitudinal sectional view through the outlet spout according to the invention

[0146] In the figures, the same reference symbols are used for identical or similar components, even if a repeated description is omitted for reasons of simplification.

[0147] Figure 1c shows a perspective view of a dispensing tap assembly 1. Shown are a pivot lever 2 and a spout 3, with which the dispensing tap 4 is connected via a beverage line 5 (shown as an example) to another dispensing system (not shown in detail) or a dispensing head and a beverage keg. The dispensing tap 4 is at least partially enclosed by an attachable housing 6. The housing 6 itself is shown again in Figure 2c. The spout 3 is integrated into the housing 6.

[0148] Furthermore, Figure 3c shows a partial detail of Figure 1c. A customer-specific evaluation electronics unit 7 / wireless communication unit is arranged in the housing 6 itself. This unit can communicate, for example, via radio, e.g., Bluetooth, with a gateway or higher-level processing unit (not shown in detail), or it can also operate independently without it. The evaluation electronics unit 7 is connected via cable to sensors 10, 11, 12 arranged in the outlet spout 3. Furthermore, a battery 8 for supplying power to the evaluation electronics unit 7 / wireless communication unit is arranged in the housing 6. A display 9, for example, an LCD display, can be arranged on a front side so that the temperature of the beverage 13 to be dispensed and / or the flow rate of the beverage 13 to be dispensed can be read during the dispensing process.In addition, the display 9 can indicate the keg fill level, an upcoming keg change, and the battery capacity. Another possible solution is to have a

[0149] REPLACEMENT SHEET (RULE 26) To have a multifunction button, e.g. to send a message to the cloud or other functions.

[0150] Figure 4c shows the spout 3. This spout is detachably connected to the tap 4. This allows the spout 3 to be removed for replacement or cleaning. Furthermore, commercially available spouts are also plugged into the taps, so that the spout 3 according to the invention with sensors 10, 11, 12 can be retrofitted to a tap 4.

[0151] Figure 5c shows the outlet spout 3 in a side view. A temperature sensor 10 and two flow sensors 11, 12 are provided.

[0152] Figure 6c shows a longitudinal sectional view through the outlet spout 3 according to the invention. The beverage 13 to be dispensed passes through the outlet spout 3 in its longitudinal direction 14. The first flow sensor 11 is formed by two opposite contacts

[0153] 11.1 and 11.2. Once the beverage 13 has reached the two contacts 11.1, 11.2, an electrical connection is established. The first flow sensor 11 is connected to the customer-specific evaluation electronics 7 via a connecting cable. This detects a flow. Furthermore, the beverage 13 can be measured with regard to its current temperature via the temperature sensor 10, which is also connected to the evaluation electronics 7, but not shown in detail. The beverage 13 then passes the second flow sensor 12 in the longitudinal direction 14. This also has two opposite contacts 12.1 and

[0154] 12.2. The two flow sensors 11, 12 allow a flow rate or volume flow to be determined in the evaluation electronics 7. Using the information from an external processing unit regarding when a new barrel is tapped, the evaluation electronics 7 can thus draw conclusions about the fill level of the barrel. The display on the housing 6 can thus, for example, show the fill level of the barrel or signal an impending barrel change through a simple visual display, for example, a red LED.

[0155] REPLACEMENT SHEET (RULE 26) Any or all of the features of this invention may be combined with any or all of the features of the inventions listed above and / or listed below.

[0156] REPLACEMENT LEAF (RULE 26) The present invention further relates to a fitting arrangement for a beverage keg having the features in the preamble of patent claim 26.

[0157] It is well known in the art to store beverages for consumption in containers. This allows for transport from the beverage production site, such as a brewery, to the place of consumption, such as a restaurant.

[0158] Common containers for beverages are bottles, cans, and kegs. In the latter case, it is possible to provide larger quantities of the respective beverage, for example, more than 10 liters, especially more than 20 liters, and preferably more than 30 liters of the beverage in a keg.

[0159] In order to fill the beverage into the keg at the filling point and extract it at the tapping point, it is known that the beverage is dispensed from the keg under pressure with the aid of a gas. CO2 is used in particular for this purpose. The beverage kegs have a keg body with an outer shell. The keg body is usually made of a metallic material. The keg body usually has an opening in the middle of its top side into which a fitting is inserted. The fitting serves as a coupling point for filling the keg. Once the filling process is complete, the fitting remains on the keg and has a seal or sealing arrangement so that the beverage filled into the keg remains sealed and, if necessary, under pressure.

[0160] At the dispensing point, the beverage keg is connected to a dispensing system. There is a gas line for introducing the gas into the beverage keg and a beverage line for dispensing or extracting the beverage from the keg. For this purpose, a dispensing head is used, which is connected to the fitting, particularly in a form-fitting and fluid-tight, yet detachably connected manner.

[0161] Since the barrel body itself is usually made of a metallic, i.e. non-transparent and opaque material, and since the barrels are often cleaned after the initial filling and refilled dozens of times, it is necessary to obtain information about the respective barrel contents and, if necessary, further information about the barrel and / or the fitting.

[0162] REPLACEMENT SHEET (RULE 26) For the reuse of the fitting, external markings, for example with stickers, labels or even permanent markings, for example by engraving with a laser, are only suitable to a limited extent.

[0163] From GB 383 900 A a riser pipe is known into which a transponder is cast by means of a sealing mass, for example rubber material.

[0164] The present invention therefore has the object of providing a beverage keg, wherein information about the beverage keg and optionally about the beverage remains rewritable and non-detachable on the beverage keg.

[0165] The above-mentioned object is achieved according to the invention with a fitting arrangement according to the features in claim 26.

[0166] Advantageous embodiments are described in the dependent claims.

[0167] The fitting assembly for a beverage keg comprises a fitting sleeve with a preferably spring-loaded and, depending on the design, sometimes relatively movable riser tube arranged therein, as well as a seal. The fitting assembly, in particular the sleeve and the riser tube, are made of metallic material, in particular of a food-grade material, such as stainless steel. The seal is located between the fitting housing, in particular on the inner surface of the fitting housing, and the riser tube, and thus seals the riser tube against the fitting housing.

[0168] According to the invention, the fitting assembly is characterized in that an electronic data carrier is arranged on or in the seal or a cover located above it. The data carrier is, in particular, an RFID tag or an NFC tag. This makes it possible to store information on the electronic data carrier, which in particular, individually or cumulatively, but not exclusively, contains the following data:

[0169] - Age of the seal and / or fitting

[0170] - Information about the barrel, in particular age and / or fitting changes and / or fillings of the barrel.

[0171] REPLACEMENT SHEET (RULE 26) - The capacity of the keg can also be stored. In particular, however, the age, type or brand, and / or bottling location of the keg contents, i.e., the beverage contained in the keg, are recorded.

[0172] - Furthermore, information relating to the keg pressure, for example, can be provided. With additional sensors coupled, conclusions can be drawn about temperature, keg pressure, and / or the transport of the keg and the beverage content contained therein.

[0173] - Best before date of the drink

[0174] - Name of the drink

[0175] - Brewery / Manufacturer.

[0176] The data storage device itself is designed to be energy-free, meaning it has no active energy source.

[0177] The data storage device itself is, in particular, rewritable. It is particularly preferred that the data storage device be protected by a code or password. This means that writing to the data storage device is only possible with special technical tools and authentication. This prevents misuse or incorrect overwriting.

[0178] The fitting arrangement is particularly suitable for reading data with appropriate reading hardware. This can consist of a smartphone with appropriate software or an app, so that during the delivery of beverage kegs to a wholesaler's transshipment point or at a delivery point for an event or a restaurant, the respective keg can be randomly checked for contents, filling date, type of beverage, etc. The kegs can also be recorded at least partially or fully automatically at the breweries or transshipment points. This way, information such as the number of keg rinses performed or the dates and contents of the filling are stored. Furthermore, the manufacturer can integrate the tag writing fully automatically into their filling plant or a downstream point in the process chain.

[0179] REPLACEMENT SHEET (RULE 26) However, the fitting arrangement is particularly suitable in conjunction with a sensor system in a tap head. This makes it possible, for example, for the innkeeper or a higher-level brewery to identify where a specific keg containing the filled beverage is on tap or connected to a dispensing system.

[0180] In order for the electronic data carrier to be able to be integrated according to the invention, it has proven advantageous that the data carrier is preferably arranged either in the seal, and here in particular in an upper region of the seal in the vertical direction or towards the dispensing head, or that the data carrier is arranged on the seal. If the data carrier is arranged on the seal, a cover is arranged over this. The data carrier can preferably be self-adhesive and can thus be arranged on the seal or the cover. The seal is made of a rubber-like material, in particular an elastomeric material. The cover is preferably made of a material that does not provide electronic shielding, for example a plastic material. This makes it possible to read out the data on the data carrier or to store it on the data carrier, despite the fact that the data carrier itself has no active energy source.to label the data carrier, and to do so wirelessly. As an alternative to the arrangement on the top side of the seal, the data carrier can also be arranged on the underside of the seal, in particular by bonding it to the seal.

[0181] Because the data carrier is either located in the upper area of ​​the seal or covered by a cover, it is not in direct contact with the beverage or cleaning media. Furthermore, when filling or when a dispensing nozzle is used, the data carrier is not exposed to abrasive wear or direct mechanical contact. This makes the data carrier particularly durable, particularly readable and rewritable for the lifespan of the seal or fitting.

[0182] For the production of the data carrier, for which food-grade material should preferably be used, it has proven particularly preferred, especially in

[0183] REPLACEMENT SHEET (RULE 26) In the case of an RFID tag or NFC tag, electronic conductor tracks are provided on a plastic film or a dimensionally stable material such as a plastic ring or a PCB (so-called FR-4 glass fiber composite material) and the data carrier is then poured into the seal or the cover is poured onto the seal or attached to the seal cover. This process is called overmolding. During the overmolding process, the circuit board or the conductor film of the data carrier can melt at least partially, but in particular completely. Because the seal or the cover is not electrically conductive, the conductor tracks of the data carrier are electrically insulated from one another, in particular from direct contact, so that the functions are retained after the seal has been produced or after a cover has been applied to the seal.The data carrier according to the invention can thus have a construction height of less than 0.5 mm.

[0184] It has proven particularly advantageous to mount the data carrier on a rigid ring carrier and then attach it to the underside of the sealing cover using epoxy resin. This creates a chemical / positive connection, which, with no gaps or other irregularities, is particularly suitable for use with food. Even if the assembly is located outside the drum, the use of bonding material approved for food contact is recommended. This same connection must, of course, withstand the thermal, chemical, and mechanical stresses of a drum's life cycle. And the space required by the data carrier and bonding material can be compensated for by optimizing the design of the elastomer seal in such a way that the assembly consisting of the seal and data carrier, including the TAG, is 1:1 interchangeable with the seal and carrier assembly as before and currently on the market.

[0185] For other fitting design variants (especially A- and G-types: Figure 8d), arranging the data carrier in the main seal is particularly effective. Thus, the integration of the data carrier into the overall product by replacing the seal in existing fittings is also conceivable. The design can thus be carried out during the seal manufacturing process by inserting the data carrier into the seal production tool.

[0186] REPLACEMENT LEAF (RULE 26) such that the data carrier is inserted / held in the mold and overmolded with elastomer. Alternatively, the data carrier is attached to / into the seal after the production process, or subsequently inserted into a separate carrier part in the top side of the seal, or arranged on the underside of the seal.

[0187] Further advantages, features, properties, and aspects of the present invention are the subject of the following description. Preferred embodiments are the subject of the following description. These serve to facilitate understanding of the invention. They show:

[0202] REPLACEMENT LEAF (RULE 26) Figure 1d shows a cross-sectional view of the fitting arrangement 1. A fitting housing 2 has an outer seal 3 for being arranged in a fluid-tight manner in a beverage keg 13 (not shown in detail). The seal 4 is arranged in the fitting housing 2 and is inserted in a form-fitting, fluid-tight manner into an upper end 5 of a riser pipe 6. For this purpose, a sealing body in the form of a ball 7 with a helical compression spring 9 is inserted, so that the ball 7 is brought into form-fitting contact with an inner sealing surface of the seal 4 against a spring force. For this purpose, curvatures 8 directed into the riser pipe 6 are formed, which hold the helical compression spring 9 in a form-fitting manner in the riser pipe 6. Furthermore, a helical compression spring 10 surrounding the riser pipe 6 and a retaining ring 11 are arranged, which press the entire riser pipe 6 from the inside into the fitting housing 2.Furthermore, the fitting housing 2 has recesses 12 in its outer surface. Furthermore, the seal 4 is arranged between the fitting housing 2, specifically an inner side of the fitting housing 2 at a sealing surface 17, and the riser pipe 6. The seal 4 thus seals the fitting housing 2 from the riser pipe 6. The riser pipe 6 itself can be arranged relatively movably within the fitting housing 2. However, the riser pipe 6 can also be fixed in the fitting housing 2, in which case another valve body is mounted in the riser pipe 6.

[0203] Figure 2d shows a cross-sectional view through an assembled fitting arrangement 1, wherein the fitting arrangement 1 is inserted into a beverage keg 13. For this purpose, a gas side 14 is formed in the beverage keg 13 itself, as well as in the riser pipe ß itself and below the fitting arrangement 1, provided that the beverage keg 13 is oriented upwards relative to the vertical direction V. In particular, the gas side 14 is formed between the fitting housing 2 and the riser pipe 6, which is realized by the recesses 12 in the fitting housing 2. In the closed, sealed state, the spring force F9 thus presses the ball 7 against an inner sealing surface 16 of the seal 4. A beverage present on the beverage side 15 is thus prevented from escaping into the environment U.

[0204] The upper end 5 of the riser pipe 6 is widened, whereby the second helical compression spring 10 comes into contact with the entire riser pipe 6 against a spring force F10 with the seal 4 to an internal sealing surface

[0205] REPLACEMENT LEAF (RULE 26) 17 of the fitting housing 2. This also seals the beverage from the gas side 14 against the environment U when closed.

[0206] In the event of activation, a dispensing head (not shown in detail) would be positively inserted into a dispensing head receptacle 18 and would press the riser pipe 6 with seal 4 downwards relative to the vertical direction V. As a result, a gas would be conveyed via the gas side 14 into the beverage keg 13, so that when the dispensing head is connected, the ball 7 or sealing plate would also be moved downwards relative to the vertical direction V relative to the seal 4, and the beverage could thus flow out and be removed from the beverage keg 13.

[0207] The seal 4 itself is formed from a reinforcing ring 19 and an elastic sealing material 20 surrounding it. The seal 4 has an upper head section K and a web section S.

[0208] This is an S-type fitting. A data carrier 22 is arranged on the seal 4, specifically on the top side of the seal 4. This electronic data carrier 22 is arranged in the form of a circular ring or circular ring section once around the seal 4 or on the seal 4. A cover 24 is arranged above the seal 4 in the direction of a possible outlet 23 of the fitting arrangement 1, which cover at least partially overlaps the seal 4. The cover 24 also overlaps the electronic data carrier 22 so that the latter does not come into contact with the liquid or beverage in the barrel 13. To produce the seal 4 with cover 24, the data carrier 22 is positioned in particular on the material of the seal 4 or the material of the cover 24, and then both components are plugged together. Furthermore, it is possible to injection-mold the cover 24 from a plastic-like material onto the seal 4 or to mold it onto the seal 4.to be cast, particularly in the form of an overmolding process. The data carrier 22 is thus cast between the cover 24 and the seal 4 and thus sealed. Using a suitable reading device, the data carrier 22 can then be read through the cover 24.

[0209] Figure 3d shows an exploded view of Figure 2d. Here, it can be seen that the data carrier 22 is designed as a continuous circular ring.

[0210] REPLACEMENT BLADE (RULE 26) Figure 4d shows a cross-sectional view, similar to Figure 2d. However, here the data carrier 22 is cast into the seal 4 itself. The cover 24 is additionally applied to the seal 4. However, the seal 4 is first manufactured with the data carrier 22. The tag is held or positioned in the mold of the seal 4, and then the seal 4 is cast as a single piece in a single step.

[0211] Figure 5d shows an alternative design variant. Here, the data carrier 22 is cast into the cover 24. Thus, the data carrier 22 is located on the seal 4, but completely encapsulated or cast into the cover 24 itself.

[0212] Figure 6d shows an alternative design variant. A fitting arrangement 1 of the II type is shown. The data carrier 22 is arranged here on a circumferential ring 25, preferably made of metal or alternatively also plastic. The metal ring 25 is at least partially cast into the seal 4. Here, too, the data carrier 22 can first be arranged on the metal ring 25 or the metal reinforcement of the sealing body and then overmolded with the sealing material 20, also in an overmolding process. The data carrier 22 is thus sealed from the beverage, at least with regard to the outlet 23. The data carrier 22 can be partially formed laterally beyond the metal ring 25 to facilitate positioning in the tool.

[0213] Figure 7d shows a D-type fitting assembly 1, already described in Figure 1d. Here, too, a metallic reinforcement ring 19 is arranged in the seal 4 itself. Here, the electronic data carrier 22 is mounted on a reinforcement ring 19, either metallic or plastic, but sufficiently dimensionally stable, and then overmolded with the sealing material 20 in an overmolding process, so that here, too, the data carrier 22 is sealed off from a beverage to be dispensed.

[0214] Figure 8d shows a cross-sectional view through a fitting assembly. The seal 4 is arranged between the riser pipe 6 and on the inside of the fitting. The data carrier 22 itself is arranged centrally in the seal 4 and was overmolded with elastomer during manufacturing.

[0215] REPLACEMENT LEAF (RULE 26) Figure 9d alternatively shows the data carrier 22 inserted into a top side of the seal 4. For this purpose, it can be injected directly into the seal 4, but can also be subsequently inserted into a groove.

[0216] In an alternative embodiment according to Figure 10d, the data carrier 22 is arranged below the seal 4. It rests on an upper sleeve 26.

[0217] According to Figure 11 d, the data carrier 22 is completely integrated into the seal 4, thus completely encapsulated by the sealing material 20, in particular elastomer.

[0218] Some or all features of this invention may be combined with some or all features of the previously listed inventions.
