- the controller is adapted to determine in a data storage, whether the use indicator is listed as a used food supplementation vessel. In other words, the controller determines, whether the food supplementation vessel has already been inserted into a guide up to the extraction position.
- the data storage may be a local database of a beverage preparation device comprising the vessel extraction device.
- the database may also be a remote database accessible by network means, such as the internet.
- the data storage may also be implemented in the use indicator coding element and the reader may comprise a writing device that can amend the data in the use indicator coding element in order to indicate that the food supplementation vessel has already been inserted into the extraction position and that the first septum and the second septum have been pierced by the hollow needle.

- Figure 6 shows a top view of a vessel extraction device 300 comprising three openings 304a, 304b, 304c.
- Each opening 304a, 304b, 304c is connected to a slot having a guide 306a, 306b, 306c as will be explained in further detail with reference to figure 7 .
- first slot 306a connected to the first opening 304a single hollow needle 324a for extracting a fluid from a fluid vessel 204 is arranged.
- the second slot 306b connected to the second opening 304b a single hollow needle 324b for extracting a fluid from the fluid vessel 204 is arranged.
- the third slot 306c connected to the third opening 304c a single hollow needle 324c for extracting a fluid from the fluid vessel 204 is arranged.
- the first opening 304 comprises a complementary mechanical coding means 330a, 330a formed as recess in the guide and slot, respectively, wherein the complementary mechanical coding means 330a, 331a comprise a first angular distance.
- complementary mechanical coding means 330b, 331b are formed as a recess in the guide and slot, respectively.
- the complementary mechanical coding elements 330b, 331b comprise a second angular distance.
- the complementary mechanical coding element 330c and 331c formed in the slot and guide 306c, respectively at the third opening 304c comprise a third angular distance.
- the angular distance between the complementary coding element 330a, 330b, 330c, 331a, 331b, 331c allows that only a particular type of fluid mineralization vessel may be introduced in a particular opening 304a, 304b, 304c. Thereby, it may be ensured that only one type of fluid vessel 200, 200', 200" may be inserted into a particular opening 304a, 304b, 304c.
- a fluid mineralization vessel 200 is inserted into a slot, guide 306, respectively.
- the guide 306 guides the extraction cap 210, the outer wall 202 of the first section 204 of the vessel body.
- the guide 306 also guides in a recess 330a embodying a complementary mechanical coding element the mechanical coding element 230 formed on the extraction cap 210 of the fluid vessel.
- Figure 7 shows the fluid vessel 200 and its extraction position in the extraction device 300.
- a first hollow needle 324a passes through the opening 228 formed in the lid portion 222, the second septum 220 and the first septum 216 into the second section 206 of the vessel body.
- the first hollow needles 324a can extract a fluid 205 from the fluid vessel 200.
- an RFID tag 232 is arranged in the extraction cap 210 .
- a controller 106 is adapted to instruct a reader 332 to read the RFID tag 232.
- the RFID tag 232 acts as a data storage element.
- the reader 332 can read data from the RFID tag 232, for example a unique serial number or data indicating, whether the fluid vessel 200 has already been inserted into an extraction mechanism 300. The data read by the reader 332 is passed to the controller 106.
- the controller 106 determines by the data read from the RFID tag 232 that the fluid vessel 200 has not been inserted into a vessel extraction mechanism 300, the controller 106 enables the metering pump 104a to extract a fluid 205 from the vessel 200, when required for mineralizing the beverage.
- the controller 106 also instructs the reader 332 to write data 232 on the RFID tag 232 indicating that the fluid vessel 200 has been inserted into a vessel extraction device 300 and that the first septum 216 and the second septum 220 have been pierced by the first hollow needle 324a.
- the vessel extraction device 300 may comprise a position sensor 334 determining that the fluid vessel 200 has reached the extraction position. If the position sensor 334 detects that the fluid vessel 200 has reached the extraction position, the above described procedure commences.
- the controller 106 determines by the reader 332 that the data are stored on the RFID tag 232 indicates that the vessel has already been inserted into a vessel extraction device 300, the controller 106 disables the metering pump 104a such that no fluid can be extracted from the fluid vessel 200.
- the first hollow needle 324a pierces the first septum 216 and the second septum 220. As soon as the fluid 205 in the vessel body 204, 206 is depleted, the fluid vessel 200 must be removed from the guide 306 of the vessel extraction device 300.
- mineralization fluid collects at the first hollow needles 324a.
- a droplet of mineralization fluid also passes the first septum 216.
- Such droplets are undesired in the vessel extraction device 300, since the droplets and particularly the minerals in the droplets may jeopardize the operation of the vessel extraction device. Therefore, a second septum 228 is arranged spaced apart from the first septum 216. The small droplets are encased between the first septum 216 and the second septum 220 and do not enter the vessel extraction device 300. Thereby, operation of the vessel extraction device 300 is improved.
- the removable cover element 274 (see figure 2 ) has been removed from the valve seat 254, and thus the vent passage 270 and vent opening 272 as well as the recess 264 are exposed to the environment.
- the metering pump 104a removes mineralization liquid 205 from the vessel body 204. Therefore, the pressure in the mineralization body 204 falls under the ambient pressure. If the pressure in the vessel body 204 is significantly lower than the ambient pressure, accuracy of the metering pump 104a is reduced.
- the outer perimeter of the umbrella shaped membrane 260 is lifted from the lower portion 278 of the valve seat 254 and gas (air) may enter the vessel body 204 through the vent passage, vent opening and the cavity formed between the umbrella shaped membrane 260, the lower portion 278 of the valve seat and the valve stem 262, until the pressure difference between the ambient and within the vessel body 204 is compensated. After this pressure compensation there will be a small pressure difference between the vessel body 204 and the ambience will remain, which is termed residual pressure.
- the fill level of the mineralization liquid 205 is monitored.
- the invention tries to dispense with additional electrodes piercing the first septum 216 and the second septum 220.
- a fill level sensor 350, 352 is formed in the conduit 325a.
- the controller 106 determines that the food supplementation vessel 200 has to be replaced.
- the fill level sensors 350, 352 may be formed by any suitable sensor, such as an optical sensor, a plurality of electrodes.
- a first electrode 350 is arranged closer to the hollow needle 324 than a second electrode 352, wherein both electrodes 350 and 352 electrically contact the fluid in the conduit 325a.
- the first electrode 350 and the second electrode 352 are electrically connected to the controller. If the controller determines that the electric resistance between the electrodes 350 and 352 increases a predetermined level, and/or the voltage between the first electrode 350 and second electrode 352 exceeds a predetermined level and/or the current flowing between the first electrode 350 and the second electrode 352 falls under a predetermined threshold, the controller 106 determines that the level of the mineralization fluid 205 has fallen under a predetermined level and that the food supplementation vessel 200 has to be exchanged. The controller 106 of the vessel extraction device 100 informs a user to change the vessel 200.
- the controller of the vessel extraction device 100 can also store on a memory device, such as an RFID tag 232, attached to the vessel that the vessel is empty.
- the present invention has the advantage that no droplet of mineralization fluid can enter the vessel extraction apparatus 300. Further, appropriate insertion of a fluid vessels into the vessel extraction device can be assured. Further, each fluid vessel can only be used once, and abuse is prevented. The invention also ensures proper ventilation of the food supplementation vessel 200.
