Gelöst wird die Aufgabe mit einer Portionskapsel zur Zubereitung eines Getränks in einer Getränkeherstellungsmaschine, wobei die Portionskapsel ein Basiselement mit einem Flansch und mit einem Hohlraum zum Aufnehmen eines Getränkerohmaterials und einen den Hohlraum verschließenden Kapseldeckel aufweist, wobei der Kapseldeckel an dem Flansch befestigt ist und auf der dem Kapseldeckel gegenüberliegenden Fläche eine Dichtung vorgesehen ist, die Gelatine aufweist und teilplastisch vorgesehen ist.The object is achieved with a portion capsule for preparing a beverage in a beverage production machine, the portion capsule having a base element with a flange and a cavity for receiving a beverage raw material and a capsule lid closing the cavity, the capsule lid being attached to the flange and on the a seal is provided on the surface opposite the capsule lid, which comprises gelatine and is provided in a partially plastic manner.
Weiterhin gelöst wird die Aufgabe mit einer Portionskapsel zur Zubereitung eines Getränks in einer Getränkeherstellungsmaschine, wobei die Portionskapsel ein Basiselement mit einem Flansch und mit einem Hohlraum zum Aufnehmen eines Getränkerohmaterials und einen den Hohlraum verschließenden Kapseldeckel aufweist, wobei der Kapseldeckel an dem Flansch befestigt ist und auf der dem Kapseldeckel gegenüberliegenden Fläche eine Dichtung vorgesehen ist, die Gelatine aufweist und teilelastisch vorgesehen ist.The object is also achieved with a portion capsule for preparing a beverage in a beverage production machine, the portion capsule having a base element with a flange and a cavity for receiving a beverage raw material and a capsule lid closing the cavity, the capsule lid being attached to the flange and on the surface opposite the capsule lid is provided with a seal which comprises gelatin and is provided to be partially elastic.
Die zu diesem Gegenstand der vorliegenden Erfindung gemachten Ausführungen gelten für die anderen Ausführungen der vorliegenden Erfindung gleichermaßen und umgekehrt. Merkmale, die im Zusammenhang mit dieser Ausführungsform der vorliegenden Erfindung gemacht worden sind können in andere Gegenstände der vorliegenden Erfindung übernommen werden.The statements made on this subject matter of the present invention apply equally to the other variants of the present invention and vice versa. Features made in connection with this embodiment of the present invention can be incorporated into other objects of the present invention.
Die folgenden Ausführungen gelten für beide Gegenstände der vorliegenden Erfindung gleichermaßen.The following statements apply equally to both objects of the present invention.
Diese Gegenstände der vorliegenden Erfindung betreffen eine Portionskapsel, die beispielsweise zur Getränkeherstellung eingesetzt wird. Beispielsweise wird mit der Portionskapsel Kaffee oder Espresso oder Tee hergestellt. Dafür wiest die Portionskapsel ein Basiselement mit einem Boden und Seitenwänden auf, die einen Hohlraum aufspannen, in den das Getränkerohmaterial eingefüllt wird. Der Hohlraum wird dann mit einem Kapseldeckel verschlossen. Zur Herstellung des Getränks wird die Portionskapsel beispielsweise mit heißem Wasser durchströmt. Vorzugsweise unterscheiden sich der Werkstoff, aus dem die Dichtung und das Basiselement gefertigt sind. Vorzugsweise ist das Basiselement aus einem metallischen Werkstoff, insbesondere Aluminium gefertigt.These objects of the present invention relate to a portion capsule that is used, for example, for beverage production. For example, coffee or espresso or tea is made with the portion capsule. For this purpose, the portion capsule has a base element with a base and side walls that span a cavity into which the raw beverage material is filled. The cavity is then sealed with a capsule lid. To produce the drink, hot water flows through the portion capsule, for example. The material from which the seal and the base element are made preferably differ. The base element is preferably made of a metallic material, in particular aluminum.
Vorzugsweise weist die Portionskapsel eine Seitenwand und einen Boden auf. Die Seitenwand ist vorzugsweise konisch oder zylindrisch vorgesehen und insbesondere einstückig mit dem Boden verbunden. An dem dem Boden gegenüberliegenden Ende der Seitenwand weist diese einen, insbesondere kreisringförmigen, Flansch auf, der vorzugsweise einstückig mit der Seitenwand verbunden ist und in einem Winkel, insbesondere einem stumpfen Winkel, zu dieser vorgesehen ist.The portion capsule preferably has a side wall and a base. The side wall is preferably conical or cylindrical and is in particular connected in one piece to the base. At the end of the side wall opposite the bottom, the latter has a flange, in particular an annular flange, which is preferably connected in one piece to the side wall and is provided at an angle, in particular an obtuse angle, to the latter.
An einer Seite des Flansches ist in der Regel ein Kapseldeckel angeordnet, insbesondere gesiegelt, der einen Hohlraum in dem Basiselement, in dem sich ein Getränkerohmaterial befindet, abdichtet. An der dem Kapseldeckel gegenüberliegenden Seite des Flansches ist die Dichtung vorgesehen.A capsule lid is usually arranged, in particular sealed, on one side of the flange and seals a cavity in the base element in which a beverage raw material is located. The seal is provided on the side of the flange opposite the capsule cover.
Erfindungsgemäß ist die Dichtung teilplastisch und/oder teilelastisch vorgesehen. Einmal verformt bleibt die Dichtung also nicht in der verformten Form und/oder nimmt seine ursprüngliche Form nicht wieder an. Beispielsweise verformt sich die Dichtung beim Schließen der Brühkammer teilplastisch. Dadurch wird eine gute Dichtwirkung erzielt und die Dichtwirkung bleibt zumindest teilweise bestehen auch wenn der Schließdruck der Kammerteile nachlässt. Teilplastisch im Sinne der Erfindung bedeutet, dass sich der Abdruck, den die Brühkammer in die Dichtung eindrückt nur teilweise rückformt. Vorzugsweise beträgt die Rückformung 10 -40 % des von der Brühkammer erzeugten maximalen Abdrucks. Vorzugsweise beträgt die Abweichung des Querschnitts der Dichtung nach Verformung und Rückformung zwischen 10 und 40 % bezogen auf den Querschnitt der Dichtung vor der Verformung. Die Dichtung ist demnach teilelastisch und formt sich teilweise zurück nachdem der Druck von der Brühkammer nachgelassen hat. Die Dichtung unterscheidet sich folglich von einer gummielastischen Dichtung, die sich vollständig zurückformen wird, wenn der Druck der Brühkammer nachlässt. Die Dichtung unterscheidet sich auch von einer plastisch verformbaren Dichtung, bei der die maximale Verformung der Dichtung zumindest im wesentlichen erhalten bleibt.According to the invention, the seal is provided to be partially plastic and/or partially elastic. Thus, once deformed, the gasket will not remain in the deformed shape and/or will not resume its original shape. For example, the seal deforms partially plastically when the brewing chamber is closed. This achieves a good sealing effect and the sealing effect remains at least partially intact even if the closing pressure of the chamber parts decreases. Partially plastic within the meaning of the invention means that the imprint that the brewing chamber presses into the seal only partially recovers. The recovery is preferably 10-40% of the maximum impression produced by the brewing chamber. The deviation of the cross section of the seal after deformation and reshaping is preferably between 10 and 40% in relation to the cross section of the seal before deformation. The seal is thus partially elastic and partially recovers after the pressure from the brewing chamber has been released. The seal thus differs from an elastomeric seal, which will fully recover when the brewing chamber pressure is released. The seal also differs from a plastically deformable seal, in which the maximum deformation of the seal is at least substantially retained.
Biopolymer gemäß der vorliegenden Erfindung sind Polymere, die aus nachwachsenden Rohstoffen erhalten werden und/oder biologisch abbaubar, insbesondere vollständig biologisch abbaubar, sind. Die Herstellung dieser Biopolymere kann dabei umfassende Reinigungsschritte und/oder Modifizierungsschritte beinhalten.

In particular, the seal can also consist entirely of biopolymer.
Gelatine ist vorzugsweise ein tierisches Protein, vorzugsweise ein Stoffgemisch. Hauptbestandteil ist vorzugsweise denaturiertes bzw. hydrolysiertes Kollagen, das aus dem Bindegewebe verschiedener Tierarten, vor allem Schweinen und Rindern, aber auch Fischen und Geflügel produziert werden kann. Bei der Gelatine kann es sich aber auch um pflanzliche Gelatine handeln, die meistens Polysacharide sind.Gelatine is preferably an animal protein, preferably a mixture of substances. The main component is preferably denatured or hydrolyzed collagen, which can be produced from the connective tissue of various animal species, primarily pigs and cattle, but also fish and poultry. However, the gelatine can also be vegetable gelatine, which are mostly polysaccharides.
Als Gelatine kommt vorzugsweise insbesondere Gelatine zum Einsatz, wie sie im Bereich der pharmazeutischen Technologie zur Herstellung von Hartgelatine oder Weichgelatinekapseln Verwendung findet. Die Gelatine kann geschäumt sein. Dieses Schäumen kann mit einem Gas, insbesondere Luft erfolgen.The gelatin used is preferably, in particular, gelatin such as is used in the field of pharmaceutical technology for the production of hard gelatin or soft gelatin capsules.

Vorzugsweise ist die Gelatine gehärtet und/oder wasserunlöslich gemacht. Alternativ dazu ist die Gelatine gehärtet und/oder temporär wasserunlöslich oder temporär feuchtigkeitsresistent. Unter einer temporär wasserunlöslichen oder temporär feuchtigkeitsresistenten Gelatine wird beispielsweise Gelatine verstanden, die nach dem Gebrauch der Kapsel und/oder unter Umwelteinflüssen, beispielsweise Feuchtigkeit, Sonnenstrahlung und/oder Mikroorganismeneinfluss nach einer gewissen Zeit, beispielsweise nach 1-28 Tagen, insbesondere 1-14 Tagen, bevorzugt 1-7 Tagen, besonders bevorzugt 1-5 Tagen, Anzeichen einer Zersetzung zeigt.Preferably the gelatin is hardened and/or rendered water-insoluble. Alternatively, the gelatin is hardened and/or temporarily water-insoluble or temporarily moisture-resistant. A temporarily water-insoluble or temporarily moisture-resistant gelatin is understood to mean, for example, gelatin that after a certain time, for example after 1-28 days, in particular 1-14 days, after the capsule has been used and/or under environmental influences, for example moisture, solar radiation and/or the influence of microorganisms , preferably 1-7 days, more preferably 1-5 days, shows signs of decomposition.
Dies ist beispielsweise durch Vernetzung des Produktes mit einer oder mehreren Chemikalien erreichbar, also insbesondere ein Prozess, der das Molekulargewicht des Proteins wirksam erhöht. Dafür eignen sich beispielsweise Alginsäure-Alkylenglykolderivate, mit Natriumperoxid oxidierte Alginsäure, Amylopectindialdehydoktenylsuccinat, Bisacryloylurea, Bis(azidinethyl)sulfon, Bis(bromacetyl)ethylendiamin, Bis(chlormethyl)adipat, Bis(chlormethyl)diethylmalonat, Bis(chloracetyl)dimethylendiamin, Benzoldisulfonylfluorid, Bromessigsäure, Carbodiimide, Carboxylbenzylbromid, Bis(chlorethyl)urea, Chromacetat und - alaune, Cyallurchlorid, Dialdehydstärke behandelt mit kaustischer Soda, Dichlorhydroxy-s-triazin, Natriumsalz, Dichlorquinoxolinkarbonylchlorid, Diethylenurea, Diformyldihydroxytrioxanonan, Ditrioxynaphthalin, Difluordinitrobenzol, Dihydroxydioxan, Diglycidylmono(propylenchlorhydrin)ether von Glycerin, Dihydroxymaleillsäure, Di(maleimido)benzol, Di(maleimido-)hexan, Dimaleimid, Dimethylaminophosphoryl, Bis(dimethylamino)phosphorylchlorid, Dimethylbis(vinylsulfonyl)benzol, Dinatriumsalz, Tris(sulfatetyl)sulfonium-Innerethersalze, Ethylenglykol, Ethoxymethylisocyanat, Formalin(formaldehyd, Fluorsulfonylazetophenon, Glycerin, Gummi arabicum, beispielsweise oxidiert mit Perjodsäure, Glutaraldehyd, Hydroxytetramethylhydrooxazoniumchlorid, Milchsäure, Methotoluolsulfonat, Mono-I-O-bromethylmaleat, Methylendiethansulfonamid, Methansulfonsäurehalogenalkoholester, Mercaptoethylaziridin, Methylglucanopyranosid, Naphthalindisulforylfluorid, Pektinsäure, Peroxydisulfat, Phenolformaldehydharze, Phenyltriazinidinylsilan, Phloroformalin, Phosphonitrilchlorid, Phloroglucin, Polyurethan, Polyformal(e), Polyacrolein, Polyvinylmaleat, Kaliumpermanganat, Kaliumferrocyanid, Pyromellithanhydrid, Resorcindiglycidylether, Resorcin, Saccharid(e), Sulfanilinodichloro-s-triazin, Natriumhypochlorit, Natriumsalz von Dichlorhydroxytriazin, Stearylaminobenzoyl-Essigsäuure, Sucrose, oxidiert mit Perjodat,Tannin, Tetrahydroxyphenol, Trimellithanhydrid, Trimethylenbis(isomaleimid), Tris(chloracetyl)hexahydrotriazin, Tetraisopropyltitanat und/oder deren Gemisch aus mindestens zwei der oben genannten Substanzen.This can be achieved, for example, by cross-linking the product with one or more chemicals, specifically a process that effectively increases the molecular weight of the protein. Suitable for this are, for example, alginic acid-alkylene glycol derivatives, alginic acid oxidized with sodium peroxide, amylopectin dialdehyde octenyl succinate, bisacryloylurea, bis(azidinethyl) sulfone, bis(bromoacetyl)ethylenediamine, bis(chloromethyl)adipate, Bis(chloromethyl)diethylmalonate, bis(chloroacetyl)dimethylenediamine, benzenedisulfonyl fluoride, bromoacetic acid, carbodiimides, carboxylbenzyl bromide, bis(chloroethyl)urea, chromium acetate and alums, cyalluric chloride, dialdehyde starch treated with caustic soda, dichlorohydroxy-s-triazine, sodium salt, dichloroquinoxolinecarbonyl chloride, diethyleneurea , Diformyldihydroxytrioxanonane, Ditrioxynaphthalene, Difluorodinitrobenzene, Dihydroxydioxane, Diglycidylmono(propylenechlorohydrin)ether of glycerol, Dihydroxymaleillic acid, Di(maleimido)benzene, Di(maleimido)hexane, Dimaleimide, dimethylaminophosphoryl, bis(dimethylamino)phosphoryl chloride, dimethylbis(vinylsulfonyl)benzene, disodium salt, Tris(sulfatetyl)sulfonium inner ether salts, ethylene glycol, ethoxymethyl isocyanate, formalin(formaldehyde, fluorosulfonylacetophenone, glycerin, gum arabic oxidized, for example, with periodic acid, glutaraldehyde, hydroxytetramethylhydrooxazonium chloride, lactic acid, methotolluensulfonate, mono-IO-bromoethylmaleate, methylenediethane sulfonamide, methanesulfonic acid haloalcohol ester, mercaptoethylaziridine, methylglucanopyranoside, naphthalene disulforyl fluoride, pectic acid, peroxydisulphate, phenol formaldehyde resins, phenyltriazinidinylsilane, phloroformalin, phosphonitrile chloride, phloroglucinol, polyurethane, polyformal(s), polyacrolein, polyvinyl maleate, potassium permanganate, potassium ferrocyanide, pyromellitic ether, resaccharidyl ether, resaccharidyl hydride, resaccharidyl ether Sulfanilinodichloro-s-triazine, sodium hypochlorite, sodium salt of dichlorohydroxytriazine, stearylaminobenzoyl acetic acid, sucrose oxidized with periodate, tannin, tetrahydroxyphenol, trimellitic anhydride, trimethylene bis(isomaleimide), tris(chloroacetyl)hexahydrotriazine, tetraisopropyl titanate and/or a mixture thereof of at least two of the above mentioned substances.
Polysacharid ist der Hauptbestandteil von pflanzlichen Zellwänden. Vorzugsweise wird das Polysacharid in Form von Cellulose, beispielsweise Methyl-Cellulose und/oder Hydroxypropylmethyl-Cellulose und/oder Celluloseacetat, vorgesehen. Andere Cellulose basierende Verbindungen sind ebenfalls denkbar. Alternativ kann das Polysacharid in Form von Pullulan vorgesehen. Das Polysacharid kann als Mischung von mehreren Substanzen zur Verfügung gestellt werden. Weiterhin kann zumindest ein Teilbereich des Basiselements und/oder des Kapseldeckels ganz oder teilweise aus Cellulose, beispielsweise Methyl-Cellulose und/oder HydroxypropylmethylCellulose und/oder Celluloseacetat bestehen. Andere Cellulose basierende Verbindungen sind ebenfalls denkbar.Polysaccharide is the main component of plant cell walls. The polysaccharide is preferably provided in the form of cellulose, for example methyl cellulose and/or hydroxypropylmethyl cellulose and/or cellulose acetate. Other cellulose-based compounds are also conceivable. Alternatively, the polysaccharide can be provided in the form of pullulan. The polysaccharide can be provided as a mixture of several substances. Furthermore, at least a partial area of the base element and/or the capsule lid can consist entirely or partially of cellulose, for example methyl cellulose and/or hydroxypropylmethyl cellulose and/or cellulose acetate. Other cellulose-based compounds are also conceivable.
Unter Cellulosen werden erfindungsgemäß auch deren Derivate verstanden, insbesondere Celluloseether, welche durch teilweise oder vollständige Substitution der Wasserstoff-Atome der Hydroxy-Gruppen in der Cellulose entstehen. Diese Celluloseether können vorzugsweise ausgewählt werden aus der Gruppe bestehend aus Carboxymethylcellulose, Methylcellulose, Ethylcellulose, Hydroxyethylcellulose, Hydroxypropylcellulose, Methylethylcellulose, Hydroxyethylmethylcellulose, Hydroxypropylmethylcellulose, Ethylhydroxyethylcellulose und Carboxymethylhydroxyethylcellulose. Erfindungsgemäß können dabei auch Mischungen aus zwei oder mehr dieser Celluloseethyer zum Einsatz kommen.According to the invention, celluloses are also understood as meaning their derivatives, in particular cellulose ethers, which are formed by partial or complete substitution of the hydrogen atoms of the hydroxyl groups in the cellulose. These cellulose ethers can preferably be selected from the group consisting of carboxymethyl cellulose, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, methylethyl cellulose, hydroxyethylmethyl cellulose, hydroxypropylmethyl cellulose, ethylhydroxyethyl cellulose and carboxymethylhydroxyethyl cellulose. According to the invention, mixtures of two or more of these cellulose ethers can also be used.
Ganz besonders bevorzugt ist Hydroxypropylmethylcellulose. Eine entsprechend geeignete Hydroxypropylmethylcellulose wird beispielsweise auch in der Herstellung von veganen Hartkapseln im Bereich der pharmazeutischen Technologie eingesetzt.Hydroxypropylmethylcellulose is very particularly preferred. A correspondingly suitable hydroxypropylmethylcellulose is also used, for example, in the production of vegan hard capsules in the field of pharmaceutical technology.
Vorzugsweise weist die Hydroxypropylmethylcellulose in der Dichtung einen Wassergehalt von 1-23 Gew.%, noch mehr bevorzugt von 1,5-20 Gew.-%, viel mehr bevorzugt von 2,0-15 Gew.-% und am meisten bevorzugt 2,5-10 Gew.-% auf.Preferably, the hydroxypropylmethylcellulose in the seal has a water content of 1-23% by weight, more preferably 1.5-20% by weight, much more preferably 2.0-15% by weight and most preferably 2. 5-10% by weight.
Vorzugsweise wird im folgenden unter der Bezeichnung Kunststoff basierend auf Gelatine und/oder Polysaccharid und/oder Cellulose, insbesondere Kunststoff basierend auf Gelatine und/oder Hydroxypropylmethylcellulose und/oder Pullulan verstanden.In the following, the term plastic is preferably understood to mean plastic based on gelatin and/or polysaccharide and/or cellulose, in particular plastic based on gelatin and/or hydroxypropylmethylcellulose and/or pullulan.
Vorzugsweise wird das Biopolymer, insbesondere der Kunststoff basierend auf Gelatine und/oder Polysacharid und/oder Cellulose, als Film/Folie zur Verfügung gestellt, die dann geformt, insbesondere tiefgezogen wird, um die Dichtung zu erhalten. Es ist aber auch möglich das Biopolymer, insbesondere den Kunststoff, zu verflüssigen und zu gießen und/oder zu spritzen, um so die gewünschte Form der Dichtung zu erhalten. Nach dem Gießen wird das Biopolymer gehärtet, insbesondere unter Kälteeinfluss. Die so erhaltene Dichtung kann an dem Basiselement, insbesondere an dessen Flansch angeordnet werden.The biopolymer, in particular the plastic based on gelatin and/or polysaccharide and/or cellulose, is preferably made available as a film/foil which is then formed, in particular deep-drawn, in order to obtain the seal. However, it is also possible to liquefy and pour and/or inject the biopolymer, in particular the plastic, in order to obtain the desired shape of the seal. After casting, the biopolymer is hardened, especially under the influence of cold. The seal obtained in this way can be arranged on the base element, in particular on its flange.
Alternativ bevorzugt wird eine Form der herzustellenden Dichtung ein- oder mehrmals in ein flüssiges Biopolymer, insbesondere eine flüssige Kunststoffmasse, eingetaucht bis die gewünschte Materialstärke erreicht wird.Alternatively, a mold of the seal to be produced is preferably dipped one or more times into a liquid biopolymer, in particular a liquid plastic compound, until the desired material thickness is reached.
Noch mehr bevorzugt wird das Biopolymer in eine Sicke, die eine Bördelung am äußeren Rand des Flansches und der Kapselkörper bildet, eingefüllt, beispielsweise mit einer Düse, vorzugweise während sich die Portionskapsel dreht. Ganz besonders bevorzugt ist zumindest ein Teilbereich des Basiselementes, insbesondere der Flansch vorm, beim und/oder nach dem Auftragen des Biopolymers, insbesondere der Gelatine, gekühlt.Even more preferably, the biopolymer is filled into a bead forming a flange at the outer edge of the flange and the capsule body, for example with a nozzle, preferably while the portion capsule is rotating. At least a partial area of the base element, in particular the flange, is very particularly preferably cooled before, during and/or after the application of the biopolymer, in particular the gelatine.
Das Auftragen des Biopolymers kann nach dem Verschließen der Portionskapsel durch eine Deckelfolie erfolgen. Es ist aber auch möglich das Basiselement mit der Dichtung zu versehen und das Basiselement sodann zu befüllen und zu verschließen.The biopolymer can be applied after the portion capsule has been sealed with a lid film. However, it is also possible to provide the base element with the seal and then to fill and close the base element.
Das Biopolymer wird beispielsweise mittels Trocknung, Wärme- und/oder Kältebehandlung und/oder Vernetzung, beispielsweise mittels IV- oder UV-Strahlung gehärtet, bis das Biopolymer, insbesondere der Kunststoff, so weit erstarrt ist, dass er die Verwendung als Basiselement gemeinsam mit der Dichtung insbesondere in der weiteren Produktion, zulässt.The biopolymer is cured, for example, by means of drying, heat and/or cold treatment and/or crosslinking, for example by means of IV or UV radiation, until the biopolymer, in particular the plastic, has solidified to such an extent that it can be used as a base element together with the seal, especially in further production.
Durch mehrmaliges Eintauchen der Form kann eine Dichtung mit mehreren Schichten erzeugt werden. Die Form kann nacheinander in verschiedene flüssige Biopolymere eingetaucht werden. Die Schichten, die durch das Eintauchen in verschiedene flüssige Biopolymere erzeugt werden, können sich hinsichtlich ihrer optischen Eigenschaften, ihrer UV-Beständigkeit, Härte, Verformbarkeit und/oder Dichtheit gegenüber Flüssigkeiten unterscheiden.A multiple layer seal can be created by dipping the mold multiple times. The mold can be successively immersed in different liquid biopolymers. The layers that are created by immersion in different liquid biopolymers can differ in terms of their optical properties, UV resistance, hardness, deformability and/or impermeability to liquids.
Vorzugsweise ist eine Schicht, insbesondere eine Schicht, die Gelatine aufweist, geschäumt. Das Schäumen kann beispielsweise mit einem Treibgas erfolgen. Vorzugsweise wird diese Schicht mit einer Haftvermittler Schicht, die besonders bevorzugt Gelatine aufweist, kombiniert. Besonders bevorzugt verbessert diese Haftvermittlerschicht die Haftung zwischen der geschäumten Schicht und einem Metall-Basiselement, insbesondere einem Aluminium aufweisenden Basiselement. Eine weitere Schicht kann eine Schutzschutzschicht sein, die beispielsweise verhindert, dass eine Bipolymer-, insbesondere eine Gelatine-Schicht, aufweicht und/oder quillt.A layer, in particular a layer comprising gelatin, is preferably foamed. The foaming can take place, for example, with a propellant gas. This layer is preferably combined with an adhesion promoter layer, which particularly preferably contains gelatin. This adhesion promoter layer particularly preferably improves the adhesion between the foamed layer and a metal base element, in particular a base element comprising aluminum. A further layer can be a protective protective layer which, for example, prevents a bipolymer layer, in particular a gelatine layer, from softening and/or swelling.
Ganz besonders bevorzugt weist die Dichtung eine geschäumte Gelatineschicht und eine Haftvermittlerschicht, die die Haftung mit einem Aluminium-Basiselement verbessert und einer Schutzschicht, die ein Aufweichen und/oder Quellen, insbesondere der geschäumten Schicht zumindest vermindert, vorzugsweise verhindert. Vorzugsweise weist die geschäumte Schicht eine größere Schichtdicke als mindestens eine andere, vorzugsweise eine der anderen beiden Schichten, auf.Very particularly preferably, the seal has a foamed gelatin layer and an adhesion promoter layer that improves adhesion to an aluminum base element and a protective layer that at least reduces, preferably prevents, softening and/or swelling, in particular of the foamed layer. The foamed layer preferably has a greater layer thickness than at least one other layer, preferably one of the other two layers.
Vorzugsweise wird zumindest der Teil der Oberfläche des Basiselementes, insbesondere des Kragens/Flansches, der mit dem Biopolymer, insbesondere der Gelatine, in Kontakt kommt, vorbehandelt, um die Haftung zwischen Biopolymer und dem Basiselement, insbesondere ein Basiselement aus Aluminium zu verbessen. Eine derartige Vorbehandlung kann beispielsweise eine Plasmahandlung und/oder eine Behandlung mit Säure sein.Preferably, at least that part of the surface of the base element, in particular the collar/flange, which comes into contact with the biopolymer, in particular the gelatine, is pretreated in order to improve the adhesion between the biopolymer and the base element, in particular an aluminum base element. Such a pretreatment can be, for example, a plasma treatment and/or a treatment with acid.
In diesem Zusammenhang hat es sich als vorteilhaft erwiesen, wenn die Form eine Tauchform der Dichtung ist, wobei die Tauchform eine Kontur mit einem Tauchbereich aufweist, welcher in das flüssige Biopolymer eingetaucht wird. Der Tauchbereich entspricht bevorzugt einem Negativ der Kontur der herzustellenden Dichtung. Bei dem Herstellungsverfahren wird der Tauchbereich der Kontur mit einer Schicht des Biopolymers überzogen. In einem weiteren Schritt kann die Form aus dem flüssigen Biopolymer entnommen werden. Die Schicht des Biopolymers, die die Kontur der Form überzieht, kann erstarren und getrocknet werden. Ein entsprechendes Verfahren ist beispielsweise im Bereich der Pharmazie als Colton-Verfahren zur Herstellung von pharmazeutischen Kapseln bekannt. Insbesondere kann die überzogene Form während des Erstarrens und/oder Trocknens in einer oder mehreren Dimensionen gesteuert werden, um die Ausgestaltung des Basiselements, insbesondere die Form und/oder die Dicke gezielt einzustellen. Noch ein Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung der erfindungsgemäßen Portionskapsel, bei dem eine Form in ein Biopolymerbad getaucht wird und sich dabei ein Film auf der Oberfläche der Form bildet, der anschließend gekühlt und/oder getrocknet wird. Abschließend wird die Portionskapsel von der Form gelöst und gegebenenfalls noch beschnitten.In this context, it has proven to be advantageous if the mold is a dipping mold of the seal, with the dipping mold having a contour with a dipping area which is dipped into the liquid biopolymer. The immersion area preferably corresponds to a negative of the contour of the seal to be produced. During the manufacturing process, the dipping area of the contour is covered with a layer of the biopolymer. In a further step, the mold can be removed from the liquid biopolymer. The layer of biopolymer covering the contour of the mold is allowed to solidify and dry. A corresponding method is known, for example, in the field of pharmacy as the Colton method for the production of pharmaceutical capsules. In particular, the coated shape can be controlled in one or more dimensions during solidification and/or drying in order to set the configuration of the base element, in particular the shape and/or the thickness, in a targeted manner. Another object of the present invention is a method for producing the portion capsule according to the invention, in which a mold is immersed in a biopolymer bath and a film is formed on the surface of the mold, which is then cooled and/or dried. Finally, the portion capsule is released from the mold and trimmed if necessary.
Erfindungsgemäss weist das Biopolymerbad Gelatine auf.According to the invention, the biopolymer bath contains gelatin.

In
Die Portionskapsel 1 weist ein becherförmiges Basiselement 2 und ein an einem umlaufenden Flansch 7 des Basiselements 2 befestigten Kapseldeckel 4 auf. Der Kapseldeckel 4 ist dabei mit dem Flansch 7 insbesondere verschweißt oder verklebt. Das Basiselement 2 besteht aus einem Bodenbereich 6 und einem Wandbereich 8, die vorzugsweise einstückig vorgesehen sind. Innerhalb des Basiselements 2 ist ein Hohlraum 3 ausgebildet, welcher mit Getränkerohmaterial befüllt ist (aus Gründen der Übersichtlichkeit nicht illustriert) und welcher durch den Kapseldeckel 4 verschlossen ist. Auf der dem Kapseldeckel (4) gegenüberliegenden Seite des Flansches ist eine Dichtung angeordnet, die sich beim Schließen der Brühkammer verformt. Vorzugsweise ist die Dichtung zumindest teilweise aus Gelatine gefertigt. Vorzugsweise wird das Dichtungsmaterial flüssig auf den Flansch aufgetragen und härtet dort aus, insbesondere indem das Dichtungsmaterial gekühlt wird. Dabei ist das Basiselement der Portionskapsel vorzugsweise um 180° gedreht, so dass die Schwerkraft das flüssige Dichtungsmaterial gegen den Flansch drückt. Vorzugsweise wird das Basiselement, insbesondere der Flansch, vor dem Auftragen des Dichtungsmaterials gekühlt. Beim Öffnen der Brühkammer stellt sich die Verformung nur teilweise zurück. Nach dem Öffnen der Brühkammer verbleibt folglich eine Deformation in der Dichtung zurück. Die Dichtung formt sich teilweise elastisch zurück, nimmt aber nicht ihre ursprüngliche Form ein.The
Die Portionskapsel 1 wird im Gebrauch in einer Getränkeherstellungsmaschine in eine Brühkammer eingeführt. Anschließend wird die Brühkammer geschlossen, beispielsweise indem zwei Brühkammerelemente relativ zueinander bewegt werden. Dabei werden der Kapseldeckel 4 und der Bodenbereich 6 nacheinander oder gleichzeitig perforiert und durch die Perforationsöffnungen im Kapseldeckel 4 Extraktionsflüssigkeit unter Druck in den Hohlraum 3 eingeleitet. Durch die Wechselwirkung zwischen der Extraktionsflüssigkeit und dem Getränkerohmaterial entsteht das gewünschte Getränk, welches die Portionskapsel 1 durch die Perforationsöffnungen im Bodenbereich 6 verlässt und einem Getränkegefäß zugeführt wird. Durch das Filtermedium 9 werden etwaige Partikel des Getränkerohmaterials aus dem Getränk gefiltert und in der Portionskapsel 1 zurückgehalten. Beim Schließen der Brühkammerelemente wird die Dichtung 11 verformt, d.h. nach de, Brühen bleiben Spuren der Brühkammer in dem Dichtungsmaterial sichtbar, die jedoch geringer ausfällt als die Verformung der Dichtung bei geschlossener Brühkammer.In use, the
