Thb px%am$, relates to a drinks (beverage) capsule for creating a drink (beverage) ingredient contained in the capsule, In particular., It capsule which compete a ©ode, said code able to contain information on ire drinks ingredient contained in the capsule or on other characteristics of the capsule, and being able tobe decoded by a brewing machine, fisc invention moreover relates to a drinks (beverage) preparation spieni comprising a drinks capsule and a brewing machine, and to a method for Idcutilying a drinks capsule inn brewing Machine,

Specifically, the present invention relates to a capsule for drinks preparation in a brewing machine, said capsule comprising a capsule beaker filled with a drinks ingredient and basing an essentially square base, and a capsule cover which is fastened on tire capsule beaker. The capsule as a whole is thereby preferably essentially cubic, Ire, the lateral walla of t&a· eeutreetihe base and the cover have essentially the same square shape an the bass and the cover, lire lateral edge length however can also he larger or smaller, so that an resserdMIy cuboid capsule then arises.

Capsules of this type are known from BP 1119332 All (WO l2C)lb(l:li§43 All, WO 20135)969851, WO 2105/0969%5 and WO 2015/096991. whidh are referred to here. hulls idea! portion capsules for preparing drinks, in particular hot drinks (beverages) such as coffee, tea, chocolate drinks or milks drinks are enjoying increasing popularity. Such drinks capsules typical Is comprise an extraction material, such as roasted or ground coffee or tea for example, or one or more soluble drinks ingredients such as instant coffee, milk powder or cocoa pfwder. Apart from these known ingredients, the terra “extraction material'' within the scope of the present inventiou is also to include a cleaning agent which cart be utilised for cleaning a brewing machine.

It is already known to provide drinks capsules with a code which can be read out by the brewing machine and which tor example contains information on the capsule type, on the drinks foiredient or on the pp^ntitfemwing p^pet^sfos ire capsule concerned. Capsules, m Which: a bar code is deposited on a cover membrane, amongst others are known for example from b.P 2168073, and capsules, on which a QR-code is printed, likewise on a cover membrane, are known from WO 2011/089048A1 for example. Also according to WO 02/07|498Α1, a machine-readable identifier is attached onto a cover membrane, wherein the cover and the code are feigned in a rotatiunaily wmmetrieal manner* is* BF 2F 43206A1,, whore capsules wilts g detieeiing means f#« tb& thii flow %iiftin. The capsulo are described, amongst other :ihings capsules with a code which, is deposited m- the acftpl capsule body, on a side wall arc also shown.

It is ihieed teiatpeiy simple 10 deposit a code: on a cover membrane which ss 10 say oa a capsule cover. fhe covers are often printed in any ease and can he provided with a code with only little additionally eft'ori. However, the reading-out of die code on the ower is difficult, particularly given a.:hofiAmtai arrangement of the capsule in a brewing machine, with which the water is mostly mtodncsd thtough. the capsule base;,: and the brewed product exits through die cover metnbraue which, is to say through the cover: arid is led into the enp, A detection unit which: Is provided In the brewing chamber at the side of the capsule cover is fherclore always exposed; to: a contamination, by way of drinks residues:, splashes, etc. Mmeovet, one typically wishes to: keep the path between the exit of the drink out of the capsule and the eup as slant: as possible, and: tor this reason it is quite a cbaliengoio Be abic to accommodate the detection onft at all. 1¼ solutions which arc described in EP 2168073 and In WO 201l../(>89048Al are there tore not Statable :ler capsules which are Brewed in so-called1 horizontal brewing machines, he. in a horizontal alignment.

Further disadvantages of the state of the art lie in the applied codes themselves. The quantity attii: type :t>;f Information which can be coded into a bar code Is very limited, QR-codes and similar, known 2-1) nodes, although: being able to contain and node very much more information, however due 10 their structure are only suitable tor the application on drinks capsules to a limited extent, if these are to he read out in brewing machines, A common problem on reading out a node provided on a capsule, in a; Brewing machine, are specifically the contanhnaions which arise due to splashing of drinks, line deposits and the like, and such contamination can occur on the read-out optica, as well as on the capsule itself, depending on the mmmiftg of the capsules,

Oommon, dpkai 2-0 codes comprise all; so-called finder pitmens, whose successful recognition is absolutely necessary, in order to be able to read out the code. If a local ecettmnluafton is now located right In the region of the finder patmtu, then the complete code Becomes unreadable. This then leads to art error notice, depending on the programming of the machine* and this demands a removal of the non-madaB!e capsule, if such a problem cannot he overcome by way of cleaning the read-out opties or the capsule, then the capsule - which per so is constnnalie -must possibly even he throw?·! away, which is of course not acceptable from the customers point of view:. The demands upon the optics of the camera and on the coinputation capability of the processor of the detecMeo unit in a brewing machine fire dillicnli to meet wA. ait aceaftahie effort with mgard to eosi; and space, in; the ease of die known 2-P bodes, § Is therefore an facet of the present invention, to provide a capsule of the mlfanly mentkmed type -wMoh.it ptwAd 'With a code, said code being able to stem a sufficient quantity of klhsmailonand being able M: be read out in the brewing machine in a rapid marmer and with m extremely high success rate. li. .& iurtbpr m. plpct of the.

According to the Ittverttiom at least one fat optically readable code, which is to: say one which is visually and directly recognisable in the visible region, and/or for exaiapie m dm mimed region or possibly ultnv-vsoie? region, by way of suitable aids (camera with a sensor sensitivity in tite infinred region or the likes is provided on the base:ef fa Chpfa beaker,. Ibis: code comprises a two-dimensional arrangement of several first code elements. The first code is; thereby divided Into a regular Imagined: arrangement of code fields which at least k pairs: are grouped Into code groups. Thereby, within a code group, only a single code field is provided with a code element. A code group can consist of at least two or more code fields. The number of code fields which are grouped together into a code group can be arbitrarily large, Ihe individual code fields are typically termed in a reetanplar or square Manner. They typleally^^ fomt a type: of grid or ή type of raster, which extends oveMhe complete smlaee area of the code. Ihe feamte, according to which the code is subdivided into a regular imagined arraapment of code fields gtoupd together at least in pairs into code gmiips, wherein only a single code field within a code group la provided with a code clement. Is to be understood m that the gfid points of a regular gird in each case comprise a code element or do not comprise a code element, wherein die grid points are grouped into groups of grid points which are atiaeent to one anofan and wherein each of these groups comprises precisely one code element. Alternatively, it is moreover also conceivable not to provide exactly one code element per poop, but very generally a fixed man her Of code elements per group of code fields or of grid points, Thus; for example, it each: ease always exactly two; code fields within a iroup of four code fields can be provided; with: a code element in each ease,

Aftaehmg the code on the base of the capsule, and: not on a cover, or, as described; In, the: state of the art cited above, on a cover membrane, has various advantages. The capsule cover is therefore available for a decorative print iir infbrrnafioa which can be read by the user, or the: like, and me fashioning of the cover is nor compromised by an additional eode. llowevef, supplememarily or alternatively 10 a printing of the capsule cover, one also does not mie out the base ol the capsule beaker comprising further visually recognisable information additionally to the code, tor ok ample decorative elements, a characterisation or other information in a suitable form, which can be read out. In particular, the code can also: lie suitably integrated into a decorative element tor example.

Motmryety due to: the itieorpGratton of the code on: tie 1¾¾ a detection: unit In a hortxotttal Imtwmg machine can be Mtanged ahead of the: brewing ebatnber, Le, upstream of the: brewing chamber where there la less danger of eondapination due to tlte splashbtg tfdrinbs or tie β|%,8ΐϊί.^.Μ!ί8ΐϊ®^^^ΐ8 less critical.

Xhe grouping or bringing-together of several code fields into, a code group is advantageously homogenous and uniform over the entire surface of tie code, fit: particular, one can envisage all code fields of tie code being subdivided into code groups which with regard: to the surface area are equally large and are non-overlapping and continuous. In particular, one envisages the Individual code groups of the code lying next to one another In the surface ofthe base of the capsule beaker in a gapless manner, typically, each code group has art ideifocai geometry and code fields. over the entire surface of the iwwdtmensiorsal code, which is to say a hbnfogpbbbs: Surface density of code elements results over the surfocc of the code, inasmuch as the evaluation of die density is effected on the basts ofthe raster ofthe code groups, due to the fact that each code group is provided with exactly one code dement, or alternatively, very generally with a fixed number of code elements, M lomogencous enriaee density of code elements on the base of the capsule beaker is advantageous for "the attachment {dcptistting) of the code. The code w hich can be iasdred onto or iasered into the base by way of laser: mitatipn, specifically can be written at a constant speed.

Moreover, a uni form Of homogeneous distribution of code elements over the surface of the code is advantageous for an integrity test of the code, as well as for a redundancy of the code information stored in the code. Even before the actual decoding or decrypting of the cone, already on the picture level one can determine whether if is the ease of a designated code of a capsule envisaged tor the brewing machine or for example the case of a product counterfeit, by wav of simple means of a: picture recognition and picture evaluation which are simple and Inexpensive to totalise. The occupancy of only a single code field within a code group, or very prteraly of a lxed number of code fields within a code group, inasmuch as this is concerned represents a first test: criterion for: m integrity test If for example several code elements:: :dfo located within a code grouper i>r example several code group» without a ample code ok mom are present, then Ms is at least an Mleaferi that with regard to the capsule* aria not a capsule for the brewing tte oodeor foe imaging optics of foe detection unit of the foe wing which is M say dirtied.

The described test criterion can already be effected on the picture level which ts to say without any decoding of io&nmarioP: or of kdMtual ihfonuatfos bits. Inasmuch m this Is concerned, only ah eforenmly low computation power is neeessutw for the first integrity test. Moreover the result of foiy fimt integrity testis already ayatlable after a relative short time, so thfo the Integrity teat which Is to say the codemeoghitfon and the code: evaluation leads to hardly any delays In the designated operation of the brewing maelloe., even; whist nsfob oorfiptnativcly foevpeosiye and low-capability hardware and software.

Moreover, if is also eoneefoable to eumpieteh male do without an integrity test on the bit level which is to say after dt durihg the read-out of code information.

According to a fhrther erubodimentj, one envisaps the: local: position of a code element within the code group containing information.

What is merely; necessary is tlaf they are reeogfosahle as code efements* for example by way of them, having si least one certain., defined characterishc (nnrdmam area» base shape and: alignment, etc.).

Tire subdivision of the code into code fields ami code group§di-uaambiguously specified for each code. In a simpleat embodiment, a code group comprises two code fields lying next to one another, If the code element is located in the first code field then this for example correspondsTo a;g#o bit, and lithe single code clement h located in the seetuul node leii, this can correspond to a one bit. A code group consisting of two code fields can ite represent information of one byte.

According to comprise at least lour code fields.

Advantageously, one bather envisages a code group comprising at least an even number of code fields. Λ code group for example can also comprise sk* eight, tenotiwelye or more code fields or consist of these, A code group which is termed from four code fields has an fofomraiion content of 1’ bits, and. a code group; formed from eight code fieldx'haSjan io&amp;mtados content of 3; bits (2"), '1%: pode- groups §®P:4ypicali|t"<|®aipii l&amp;lt square or rcetapfiar manner, fcaamueh as. -this-ia^emtdemed: they rnch comprise a regular arrangement of individual code fields which he next to one another, for example, a code group finned from, lour code fields can have a square gvwoetfv wtth two code fields hm< nev to mu aaothe; amt two code livid\ firng abote one another. Moreover, with a code group of four code Is to form a row or a column with lour code fields which he next ip one another orbelow one another, sMd rdw thwt corresponding to the code group in each case.

The regular subdivision of the code into code fields and the occupancy of a code group formed frqfo code fields* it each: case by only a single code element lead to the; rcspetlve code* With itgairdid code: groups, having a homogeneous; density of code elements over fitC iSurfaee of the eode, Ipasmucfr is this: is concerned, the presence of a honmgeoeous infonuaiop. density cun represent a; plausibility· or test criteiion dreatly nn a picture level of dm coda, % way pf which criterion read errors are recognised, said errors tug, befog able to be caused by way of contaminaien and can fee erroneotply Interpefod by the defeefitm tuih and/or a subsequently connected control as Code elements. The position of individual or several code dem«foS*. represent a test criterion or plausibility criterion, in the same way and manner. .^gecdilhjg: iteW'llallM embodiment, several code groups and/or code fields are brought together into a code word, The number of code groups and code fields In a code word can be whited foi-ap, a^ltmryvrnanner.. iypicaliy, each code word has an identical number of code starts which is ta f&amp;f an ibenhea! «te of code groups. !% the division is© code winds, « can envisage each code word consisting of on .integer number ofcode groups, Moreover, it Is conceivable tor a code word to comprise tor example one or more code groups as well as individual code fields, In parficuiar, a code word cap nave an odd multiple of code fieldse

In particular, it is conceivable for example for 1,5 code groups to be brought together into a code word. If the code groups far example eompise four code fields in each ease, then a code word can consist for example of six code fields, of which four code fields are brought together into a code group, wherein the remaining two code fields belong to a further code group wbieh lies only partly within the code word. Hereby in particular one can envisage one or more code groups contained completely in the code word functioning as carriers of the code or encrypted: information,, whereas individual code fields of the code word -which lie outside the respective code groups provide one or more test bits, by way of which an integrity test of the code can also he earned out on the bit level. A tether integrity test of the code can he effected with stipulation that each code word comprises an identical number of cede elements, The position of code worts, code groups and: code fields relative to the visually recognisable code elements of the code can also be determined by way of this test criterion which is to be carried out on the picture level in p r ocular, v uu d plm-sb bn ued'm qumirv uww can be mvfomomed ms ddterem code levels, It is conceivable lor a first: test to be: elihefed with regard to a defined geometric shape of Individual code elements. If for example a node element having a geometric structure ddfetlng ineu a predefined foi example I -shaped geometry w to -,d out then ahead} Uns e m ted to a rejection, or a correct recognition of the code,.

The Implementation of a tether test criterion or f unity criterion Is also posfihle on a further, tor example second axle level. For example here, on the picture level, one can directly examine whether an envisaged number of code element is located within a predefined surface segment of tire plane, Thus e.g, an integrity test can be carried: but at the: level of each or individual code groups or code fields, E.g,, oue can examine whether a code group comprises precisely one Code element in each case, The test criterion w not fulfilled if Several or less than one code element is present per code group.. To the same extent, this can then Serve tor the correct recognition of the code or one which is to bo corrected.

According to a tether embodiment, foe code information which is stored in the eode ts redundantly contained In several code words» winch is to say tedundanify in the eodfo Tte redundant and. multiple deposition rtf code information: in the: Code and: a suriaeed dlstribidfon of the code information In the code render the decoding of the eode extremely robust with regard to external negative influences and errors, Inasmuch as this is concerned. 51 ts sufficient it only port-regions or a single part-region of the code can be visually read out ami accordingly decoded, tor reading out and decoding'llp^^l^iia imboanfoou.

Use cods information typically comprises lafof^ a special brewing pograny lor exalnple; a predefined number; of as- mewing program. The code information however can also comprisefurther informaUon emieetnhtg the brewing procedure in detail, seen as fe example; abrewing temperatee, a brewing pressure, a brewing time as well as brewing quantity or water quantity and/or pm-mfosiop time, -§it£fe:fo#maatk>n ears be represented as a sequence of individual tiia The conversion of the Intbrmrdlop to tbc stored in s he code, into an information bit ^p^n#M^fe^^:aceoidmg to a prede&amp;ed procedure. This for example can be stored in a eonversiontable, Is. sequence of foformaion bits can moreover be extended by a certain uuniber of test bits.

This can be el levied with the help of a predefined algorithm, depending on the coded irsfotmation. Said additional test bits can be used: for integrity testing theltfoirmation eonlained in the information bits. The test hits can be computed at any time from a given bit sequence of mformrnion. if these agree with the test bits which have been determined front a htiber bit sequence, for example from a further code word, it Is then to be assumed that: foe associated information which Is to; say the bit sequence represeiiipg the information is correct, ik present if foe test/bimsof dillerenf ceidei words ia

Finally, It is also conceivable to also carry out a plausibility test on the level of individual oj several code words. Thus in particular individual test bits contained in code words can be selcenxch mao and evaluated for the plausibility condos -\ cony Ίο < do* cbm-,· of the ode is tu > i\\ >sai> lomxd nlau-ub lm m qualm tesl\ winch ha\o von fox 'bed .hove.

Basically, only a certain number of code fields,, code groups or code words need to fee able to be read out for a decoding. The. plausibility tests and quality assessments of code elemeptSj code fields, code groups and code words can then be used. In order to make a good scleetiom tmd foe reliability of the available information can he included In the decoding process on: decoding, hi particular, ail decoding possibilities resulting in a given situation can be compared to cue another. A decision concerning the coded content can then he made with a ceftaro probability or tmstworfoiPess fey wav of foe qualify assessment of the reppeedvcK determined decoding possibilities.

Moreover, the quality of foe code, he; if reeognisabmty can be determined several times and thus to a quite reliable extent, due to the possibility of a code testing or quality determining on the level of the code elements, on the level of the code fields or code groups and/or on the O'. 0 W ' X 'VO WOivW ν'» ν'* t'VO 0 ν Tv wl Kiv" t 01' *\ ν^ .WO'.O^' &amp;f fall Icvds. independently αί this, it is generally conceivable tor ait assessment of the quality of recoded code on the picture level its he included in the computation of a grid as ^ell as in the computation of one or more grid constants terming the basis of the code.

Thus tor die code recognition. in particular one can envisage a grid or a grid constant ot the code being determined by approximation, in particular by way of soOalkxi fitting, in order to carry out a seating of the recorded code inasmuch as this is concerned. The quality of the code which is determined on the picture level can be used tor this scaling, hut also lor the positioning of a grid. The decoding of the code itself'can be effected or simplified by way of the quality recognition. Since the code is contained redundantly and several times, fot example in each code word, then on the basis of a quality determining of ail code words, those words which amongst all code words have the highest quality or highest assessment, are selected for decoding the code. Decoding errors can be minimised to &amp; high degree in this way and manner.

Should the decoding on the basw of tho.se words with the highest quality <^wo\su.ic.ut not. be possible, or not provide a plausible result, one then envisages changing the grid constant <u.dm tta w d povu < <\1 cam mg out dt ., >v\sm .e.ionneoodu wmesh w<..ok1 n a o. ocT es cm Dnm !, urn -, s .a ο K t sq ,ode elements or. the dot code m cech c.s -e emnprisme. sofonn rsw from winch one .0 scwml possible align sms us of the tovlc sn tlte plasm of the Iv" e.at he uemtmgv.no.sly derived the .ode elements themsebes t\pv tlly have a two * meswouel design .usd Live such .t geometuc contour which perinits the alignment ,>r etwmaowi >n the code elctucsus in she plate ot the base to be determined, I he , gi'sse u it mowtduti n m m cement hereby correlates to the alignment of the first code s-umd K the code elements One or more povhhle alignments sd the code can he detent lined in a reliable and unambiguous manner on the basis of a determining of the orientation of an arbitrary1 code element, due to the fact that preferably each code dement has a defined alignment to the alignment of the code fhe information concerning the orientation of the code, in particular can be con missed in each code element, so that it in at least the aligmuent of the code which estrt be recognised without furtbefc independently of the actual reading-oat and decoding, A capsule of the known type can be inserted or introduced into the brewing machine in tons' different positions due to its symmetry and its square cross section. There are therefore tour orientations for the capsule, each rotated by 90*, ttnd thus also for the code which is present on the base of the capsule, fine of sevens! possible orientations of the mode can he unambiguously determined already by way of the recognition and identification of m individual and arbitrary ivWdorxMt ώ. e > t\ λ» 1 i ho \ ou<' ode 'or u ' i u ' a η ή % orferttation of the code.

The use of so-called tinder patterns tor a 2D code thus not only becomes superfluous, but moreover the disadvantages which are described above and which arise :ipm a. diflied foonMtmnatei} indet pattern: m advantageo n s i y avo i ded,

The use of Under patterns can be completely done away with due to the foot that the code elements provide code! Information by way of their shape, and their surfaced distribution in the plane. The robustness of the code, lit particular xwtt.lt regard to local contamination cart be improved inasmuch as this ;s concerned,

This can have an advantageous effect on the realisation of a.s low and as inexpensive as possible tecnnical demands on tne optical detection unit and on a subsequently connected picture evamatiom iTe determining of oneof several possible alignments of th© code relative to a detection unit of the brewing machine can fee effected on the hasls; of of least one code elements and Its alignment irt the plane of the base or its alignment in a picture plane of a detection unit. The determining of the Mlgnmem of the code Is dtus htdependenr of the arrMpment of several code elements teMve to one another,

Ife particular, in these embodiments, the alignment of the code in: the plane of the easels contained in each code element, so that the information concerning the alignment and orientation of the capsule relative to the detection unit of the brewing machine Is redundant^ comamcd is the code. This also applies to the grid parameters form mg the bads of the code. These are also redundantly coded over the complete surface.

At voiding to a further development of this, one further envisages at least one lino section of life tirst code dements running essentially parallel to the outer edges of the esseohally rectangular or square code.

Hereby, rn particular one ean envisage the material of the base undergoing a colour change or texture change when being subjected to laser radtatibu at a certain defined w avelength region, so that, the code elements which are formed by way of libs can be visually represented in a particularly high-contrast manner. Thereby, it docs not necessarily need to be the case of a colour change which Is visible to the human eye, it as also conceivable tor a change in the reflection characteristics and/or absorption characteristics concerning 1R or U¥ mdiaiioh to be achieved by the ioMtyso that a code which camtot;1be::^»piaed by naked eye* but; by a detection unit using Ifo-Ight or UV light arises.

According to a timber embodiment; one envisages thefesf code comprising SO to 400 individual code elements and preferably 70 to 100 individual code elements, wherein these codc elements are armnpd fwo^itnensiratally and spatially distributed on the base of the capsule beaker. The individual code elements in particular are arranged to one another wttltont any overiapping. inasmuch as this is concerned they are provided os the base of die capsule beaker ip: manner distanced to one another. In total 100 to 800 bits of information can be integrated into the: base of the capsule beaker by way of the mentioned number of code dements. Herebyf in particular* one envisages a code element having an information content oi 2 bits in each case. In pSrtmttlap the information content of each and every code element is contained fo the Spatial position bf the code dement in the plane of the base.

According m a foriher embndimetaS; one further envisages the capsules1 comprising at least one second opieaiy readable code on the bare of the capsule beaker; additionally to the first optically readable code. As already is the case with the lust code, the second visually recognisable code also comprises a two-dimensional arrangement of several second code elements* which with respect to a middle point of the first code lie mdiaily othside the first code. In particular, for the first code one envisages it extending over the miudle point oi the iatseoffhe capsule beaker. The middle point of the first code can thereby roughly coincide with a pdmetrie •middle' point of the base of the:: capsule heaken

Detailed description

The capsule 1.0 which is represented in Fig. 1 and 2 comprises a pot-like capsule beaker 11 with a square capsule base 12, The capsule beaker 11 is away .from the base 12 closed with a capsule cover 16 extending over the complete cross section of the capsule beaker 11. The capsule coyer 16 and the side wall! M of; tho capsule beaker I F form an outwardly ρύροοΐΙηρΤΙαΗρ section. 18. The peripheral Oange section W apart bom a closure fimctlon, serves for mechanically unbng the capsule. A receiver 21 which is provided on a brewing. macitneMfand is typically In the tone. of an insertion or receiving shaft, can have a geometry cots&amp;^p^dlngW: the outer comma of the capsule 10 which is represented in a lateral view in lag.2, so capsule .mm he Introiaeed Into the receiver of the brewing machine 20, eoMpelimgly mm mknkiiori or ailpment, in wMeh the base 12 of the capsule beaker feces a defection unit 14.

Orven a correct poslionlng of the capsule 10 in a rear! position L wliiin the tawing machine 20, there are ml! fmr dilerent: |Kissible orientations of the capsate it) and of the rmbeaiiy readable winch is to say visually wcopiaafele code 50 pnataod on the base ;lt5: due to the sqnam pometty of the base II .of the capsule beaker 11 and of the essentially sqnam,: peripheral flange section. The different and several possible alignments of the code 50 are due ip rotations of the capsule with respect to its imagined rotation axis 15 which extends esserttiully petpendlcularl> to the base 12 and perpendicularly to the capsule cover Kx and which do particular can coincide with a geometrical noddle point of the base 12 and capsule cover lb.

The brewing machine 20 which is shown; in Fig. 3 is envisaged tor receiving at least one capsule 10 which by was ol insertion into the axxiwu 21 * an muth be held m a read pusmon 1 . In due read position 1., the code 50 provided on the onkr side of the base 12 of the capsule beaker 11 can be visually detected by way of the detection unit 24 and fed to a. picture evAafeon, by way of which pufem evaluation: the coded irdbosatlon can fee decoded. A brewing ehfeobef 26, in Which the eapstde 10 ®£i •'Mth -'fe^taetion product 4s at least partially gerferafed and the mtractiou material can fee sul^ccied to a fluid envisapd for the extraiilem procedum, in ptrtieular hot water, is located after the read position L. 1¾ extract which Is to say the drink pepared In fiis way and manner can subsequently he collected via an: outlet 20, in. a drinks vessel which is not explicitly shown. I hc spent capsule 10 can then be fed m a capture container 28 after the ferewmg procedure, and this cOMamer needs to fee emptied now &amp;nd again.

The brewi^'»aifei.20 Is mmmmx provided with a control 30, which In the one hand is coupled to tine detection unit 24 and on the other hand to the brewing chamber 26. A picture evaluation can cifber be contained in the detection unit 24 or in the enntml 30. The brewing procedure can be controlled, however at the minimum can be influenced, by reading out the code information of the capsule 10. The code SO for example can contain iufbmiaiioni COoeenUffg a preset brewing program which can be automatically selected by the control 30 by way of the mere visual recognition of the code 50. The pperaing comfort of the brewing: machine 20 can he increased and improved in this manner.

Moreover, by way of the provision of a code on the capsule., one succeeds ip only original capsules provided by the manutactufer lot: the ferewthg: maebinc :30 being: able to be subjected to a blowing: process. Product eomnerieits aa woll tssi oapmsks 10 which aldmtgb toeing art outer geometry which Is identical to that of the capsules shown In Fig. I and 1, however do not have a code or a wrong code due to them rad being envisaged for the browing machine, cart fee recognised by fc: detection unit Id or by the control 30, so that the initiation of #ie::fewlhg#»ess can be prevented.

The detection unit 24 Is represented ip: a simplified manner in the schematic representadop: according to lag, 4. The detection rant M In parheolat comprises a camera 25 which with its optical axis typically and advantageously esseutlaily coincides roughly with the middle point 55 of a first code 50 shown in r ig. 5 and (\ as soon: as the capsule 10 is located in the read position L within the. brewing machine 20. A first code $0 op the base 12 of the cppsole beaker 11 is represented schematically in Fig. 5. The first oode 50 has an at least imagined middle point 55 which lies eenirtoaliy which is to say centrally within the outer edges 54 of the first code 50.

The first code 50 moreover comprises a two dimensional arrangement, of several first code element^ 5.? bach of the first code elements 42 contains iiuwnnation, trout which one of several possible alignments of the code 50 in the plane of the base 12 is unambiguously derivable. The code 50 can he arranged in total In fbm drf&amp;rent alignments. In the X-Y plane which is represented in Figure 5 arid # and which fin detection unit 24 or coincides with, this. The individual alignments can he assumed for example byway of a rotation of the capsule 10 in each case fey 0(F with respect to its rotnrionMis:lY The: rotation axis 15 of the capsule beaker 1:1 pgli ttehy doMlP: MfMte nMglned tmddiepOinfsSdi of the first cone St). is that all first code elements 52 of the Star code 50 m:c designed: in an identical or essentially identical manner.

In particular* a pointer structure 56 can be tmambtguoasly assigned to the code element 52.

Moreover, one envisages a code group 60 comprising at least .font 0040:1½¾¾¾¾ $3,; 64 and, emailed by this, a minimum information noth a 2 bit length. Moreover, several code groups 60 and/or several code fields 61, 62, 63, 64 can be grouped together into a code word ?D> With the embodiment shown in Fig 6, the code groups 60 which are provided in the left upper square of die code 50 are grouped together Into a code word ?0 which in total comprises sixteen code holds 61, 62, 63,64.
