Description

Stand der TechnikState of the art

Die vorliegende Erfindung geht aus von einer Portionskapsel zur Zubereitung eines Getränks in einer Getränkeherstellungsmaschine, wobei die Portionskapsel ein flüssigkeitsdichtes Basiselement mit einem Hohlraum zum Aufnehmen eines Getränkerohmaterials und einen den Hohlraum verschließenden Kapseldeckel aufweist.The present invention is based on a portion capsule for preparing a beverage in a beverage production machine, the portion capsule having a liquid-tight base element with a cavity for receiving a raw beverage material and a capsule lid closing the cavity.

Solche Portionskapseln sind aus dem Stand der Technik bekannt. Beispielsweise offenbaren die Druckschriften DE 10 2012 223 291 A1 , DE 10 2013 215 274 A1 , DE 10 2012 109 186 A1 und DE 10 2012 105 282 A1 Portionskapseln für Portionskapselmaschinen aufweisend jeweils ein starres oder halbstarres Basiselement, das einen Hohlraum zur Aufnahme eines Getränkerohmaterials, wie Kaffeeröstgranulat, Instantkaffee, Schokoladenpulver, Teeverschnitt, Milchpulver oder dergleichen, umschließt, wobei der Hohlraum nach dem Befüllen der Portionskapsel mit einem Kapseldeckel verschlossen wird. Damit das Getränkerohmaterial bei der Lagerung und beim Transport der Portionskapsel sein Aroma nicht verliert, ist das Basiselement gas- und flüssigkeitsdicht ausgebildet. Zudem muss das Basiselement bei der Herstellung des Getränks vergleichsweise hohen mechanischen Kräften standhalten, da die Extraktionsflüssigkeit unter hohem Druck und mit hoher Temperatur in den Hohlraum eingeleitet wird, um unter Wechselwirkung mit dem Getränkerohmaterial das Getränk zu erzeugen.Such portion capsules are known from the prior art. For example, the publications disclose DE 10 2012 223 291 A1 , DE 10 2013 215 274 A1 , DE 10 2012 109 186 A1 and DE 10 2012 105 282 A1 Portion capsules for portion capsule machines each having a rigid or semi-rigid base element, which encloses a cavity for receiving a raw beverage material, such as roasted coffee granules, instant coffee, chocolate powder, ground tea, milk powder or the like, the cavity being closed with a capsule cap after the portion capsule has been filled. So that the raw beverage material does not lose its aroma during storage and transport of the portion capsule, the base element is designed to be gas and liquid-tight. In addition, the base element has to withstand comparatively high mechanical forces during the production of the drink, since the extraction liquid is introduced into the cavity under high pressure and at high temperature in order to produce the drink in interaction with the raw beverage material.

Typischerweise werden bei den aus dem Stand der Technik bekannten Portionskapseln daher tiefgezogene bzw. thermogeformte Basiselemente aus Polyethylen (PE), Polypropylen (PP), Polyvinylchlorid (PVC) und/oder Polyethylenterephthalat (PET) verwendet, da solche Basiselemente kostengünstig herstellbar, mechanisch stabil, sowie gas- und flüssigkeitsdicht sind.Typically, therefore, deep-drawn or thermoformed base elements made of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) and / or polyethylene terephthalate (PET) are used in the portion capsules known from the prior art, since such base elements can be produced inexpensively, mechanically stable, as well as gas and liquid tight.

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 made available as a mixture of several substances. Furthermore, at least a portion 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, inbesondere 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 to mean 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, methyl ethyl cellulose, hydroxyethyl methyl cellulose, hydroxypropyl methyl cellulose, ethyl hydroxyethyl cellulose and carboxymethyl hydroxyethyl 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.Hydroxypropylmethyl cellulose is very particularly preferred. A correspondingly suitable hydroxypropylmethyl cellulose is also used, for example, in the production of vegan hard capsules in the field of pharmaceutical technology.

Vorzugsweise weist die Hydroxypropylmethylcellulose im Basiselement und/oder des Kapseldeckel 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.The hydroxypropylmethyl cellulose in the base element and / or the capsule lid preferably 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 am most preferably 2.5-10% by weight.

Erfindungsgemäß 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.According to the invention, the term plastic is based on gelatin and / or polysaccharide and / or cellulose, in particular plastic is based on gelatin and / or hydroxypropylmethyl cellulose 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. Es ist aber auch möglich das Biopolymer, insbesondere den Kunststoff, zu verflüssigen und zu gießen und/oder zu spritzen, um so die gewünschte Form des Basiselementes zu erhalten.The biopolymer, in particular the plastic based on gelatin and / or polysaccharide and / or cellulose, is preferably provided as a film / film, which is then shaped, in particular deep-drawn. 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 base element.

Alternativ bevorzugt wird eine Form des herzustellenden Basiselements und/oder des Kapseldeckels ein- oder mehrmals in ein flüssiges Biopolymer, insbesondere eine flüssige Kunststoffmasse, eingetaucht bis die gewünschte Materialstärke erreicht wird.Alternatively, a shape of the base element to be produced and / or the capsule lid is preferably immersed one or more times in a liquid biopolymer, in particular a liquid plastic mass, until the desired material thickness is reached.

Sodann erstarrt das Kunststoffmaterial beispielsweise mittels Trocknung, Wärme- und/oder Kältebehandlung und/oder Vernetzung, beispielsweise mittels IV- oder UV-Strahlung, bis das Biopolymer, insbesondere der Kunststoff, so weit erstarrt ist, dass er die Verwendung als Basiselement für Getränkekapseln und/oder Kapseldeckel zulässt. Durch mehrmaliges Eintauchen der Form kann ein Basiselement und/oder Kapseldeckel 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.The plastic material then solidifies, 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 for beverage capsules and / or capsule cover. By immersing the mold several times, a base element and / or capsule cover with several layers can be produced. The mold can be immersed in various liquid biopolymers in succession. The layers that are created by immersion in various liquid biopolymers can differ in terms of their optical properties, their UV resistance, hardness, deformability and / or tightness to liquids.

In diesem Zusammenhang hat es sich als vorteilhaft erwiesen, wenn die Form eine Tauchform des Basiselements und/oder des Kapseldeckels ist, wobei die Tauchform eine Außenkontur mit einem Tauchbereich aufweist, welcher in das flüssige Biopolymer eingetaucht wird. Der Tauchbereich entspricht bevorzugt einem Negativ der Innenkontur des herzustellenden Basiselements und/oder des Kapseldeckels. Bei dem Herstellungsverfahren wird der Tauchbereich der Außenkontur 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 Außenkontur 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.In this context, it has proven to be advantageous if the shape is an immersion shape of the base element and / or the capsule lid, the immersion shape having an outer contour with an immersion area which is immersed in the liquid biopolymer. The dipping area preferably corresponds to a negative of the inner contour of the base element to be produced and / or the capsule cover. In the manufacturing process, the dipping area of the outer 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 the biopolymer that covers the outer contour of the mold can 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 selectively adjust the configuration of the base element, in particular the shape and / or the thickness.

Vorzugsweise weist zumindest ein Teilbereich des Basiselements ein Fasermaterial, insbesondere vorzugsweise verdichtete und/oder vorzugsweise geleimte Cellulosefasern, auf. Das Fasermaterial kann Papier sein, das ein oder beidseitig mit Gelatine beschichtet ist.At least a portion of the base element preferably has a fiber material, in particular preferably compressed and / or preferably sized cellulose fibers. The fiber material can be paper which is coated on one or both sides with gelatin.

Gemäß einer erfindungsgemäßen oder bevorzugten Ausführungsform weist die Portionskapsel einen Flüssigkeitsverteiler auf, der insbesondere ein Biopolymer aufweist. Bezüglich des Biopolymers wird auf die oben gemachte Offenbarung verwiesen.According to a preferred embodiment according to the invention, the portion capsule has a liquid distributor, which in particular has a biopolymer.

Die Fasern des Filzes oder Vlieses können zumindest teilweise aus einem Zellulosehaltigen Werkstoff, beispielsweise Papier oder Pappe gefertigt sein.The filter medium preferably comprises a filter fleece or a filter felt, which can each be made at least partially of gelatin. For example, the fibers of the felt or fleece can be coated with gelatin. The fibers of the felt or nonwoven can be made at least partially from a cellulose-containing material, for example paper or cardboard.

Gemäß einer weiteren bevorzugten Ausführungsform ist an dem Basiselement eine Siegelfolie, insbesondere im Bereich des Bodens vorgesehen, insbesondere um eine Öffnung im Boden, beispielsweise eine Ablauföffnung, vorzugsweise reversibel, zu verschließen. Diese Siegelfolie ist vorzugsweise zumindest teilweise aus Gelatine gefertigt. Diese Siegelfolie wird beispielsweise vor dem Gebrauch der Portionskapsel abgezogen oder durchstochen.According to a further preferred embodiment, a sealing film is provided on the base element, in particular in the region of the base, in particular in order to close an opening in the base, for example a drain opening, preferably reversibly. This sealing film is preferably made at least partially from gelatin. This sealing film is pulled off or pierced, for example, before the portion capsule is used.

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.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 detached from the mold and optionally trimmed.

Vorzugsweise weist das Biopolymerbad Gelatine auf.The biopolymer bath preferably has gelatin.

In Figur 1 ist eine schematische Schnittbildansicht einer Portionskapsel 1 zur Zubereitung eines Getränks in einer nicht abgebildeten Getränkeherstellungsmaschine gemäß einer beispielhaften Ausführungsform der vorliegenden Erfindung dargestellt.In Figure 1 FIG. 3 shows a schematic sectional view of a portion capsule 1 for preparing a beverage in a beverage production machine (not shown) according to an exemplary embodiment of the present invention.

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.The portion capsule 1 has a cup-shaped base element 2 and a capsule cover 4 fastened to a peripheral flange 7 of the base element 2. The capsule cover 4 is in particular welded or glued to the flange 7. The base element 2 consists of a bottom area 6 and a wall area 8, which are preferably provided in one piece. A cavity 3 is formed within the base element 2, which is filled with raw beverage material (not illustrated for reasons of clarity) and which is closed by the capsule cover 4.

Der Wandbereich 8 kann becherförmig ausgebildet sein und kann eine beschichtete Fasermaterialschicht 10 aufweisen. Auch der Bodenbereich kann eine Fasermaterialschicht 10 aufweisen. Das Fasermaterial 10 umfasst Papier oder Karton aus vorzugsweise verdichteten und/oder vorzugsweise geleimten Cellulosefaser, wodurch eine mechanische belastbare starre oder halbstarre Formgebung erzielt wird. Die becherförmige Ausgestaltung des Basiselementes 2 wird vorzugsweise durch Thermoformen, beispielsweise Tiefziehen mittels Unterdruck, Überdruck und/oder einem beweglichen Stempel, erzeugt. Alternativ wird das Basiselement durch Gießen, Spitzgießen und/oder Tauchen hergestellt. In dem vorliegenden Fall ist die Innenseite des Fasermaterials 10 mit einer Gelatineschicht 11 versehen. Die Beschichtung dient als Feuchtigkeitsbarriere, so dass einerseits das Getränkerohmaterial aromadicht verschlossen ist und andererseits der Hohlraum 3 als Brühkammer verwendet werden kann. Alternativ können aber auch die Fasern des Fasermaterials mit Gelatine umhüllt sein.The wall area 8 can be cup-shaped and can have a coated fiber material layer 10. The bottom area can also have a fiber material layer 10. The fiber material 10 comprises paper or cardboard made of preferably compressed and / or preferably sized cellulose fiber, as a result of which a mechanically resilient rigid or semi-rigid shape is achieved. The cup-shaped configuration of the base element 2 is preferably produced by thermoforming, for example deep drawing by means of negative pressure, positive pressure and / or a movable stamp. Alternatively, the base element is produced by casting, injection molding and / or dipping. In the present case, the inside of the fiber material 10 is provided with a gelatin layer 11. The coating serves as a moisture barrier so that on the one hand the raw beverage material is sealed aroma-tight and on the other hand the cavity 3 can be used as a brewing chamber. Alternatively, the fibers of the fiber material can also be coated with gelatin.

Die Portionskapsel 1 wird im Gebrauch in einer Getränkeherstellungsmaschine in eine Brühkammer eingeführt. Anschließend werde 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.The portion capsule 1 is inserted into a brewing chamber in use in a beverage manufacturing machine. Then the capsule cover 4 and the base region 6 are perforated one after the other or simultaneously and extraction liquid under pressure is introduced into the cavity 3 through the perforation openings in the capsule cover 4. The interaction between the extraction liquid and the raw beverage material results in the desired beverage, which leaves the portion capsule 1 through the perforation openings in the bottom region 6 and is fed to a beverage container. Any particles of the raw beverage material are filtered out of the beverage by the filter medium 9 and retained in the portion capsule 1.

Das Filterelement 9 kann aus einem Filz- und/oder Vliesmaterial hergestellt sein und es kann Gelatine aufweisen. Beispielsweise kann die Oberfläche aller oder eines Teils der Fasern des Filz- und/oder Vliesmaterials mit Gelatine beschichtet sein. Beispielsweise kann das Filterelement aus einem Papier- und/oder Kartonwerkstoff gefertigt sein. Das Filterelement kann beim Öffnen der Kapsel an- und/oder durchstochen werden.The filter element 9 can be made of a felt and / or non-woven material and it can have gelatin. For example, the surface of all or part of the fibers of the felt and / or nonwoven material can be coated with gelatin. For example, the filter element can be made from a paper and / or cardboard material. The filter element can be pierced and / or pierced when the capsule is opened.

In Figur 2 ist eine schematische Detailansicht der in Figur 1 illustrierten Portionskapsel 1 dargestellt, welche den Schichtaufbau des Teilbereichs 8 verdeutlich. Der Teilbereich 8 besteht aus einem formstabilen Fasermaterial 10, gebildet aus verdichteten und/oder geleimten Cellulosefasern, welches auf seiner Innenseite mit einer Beschichtung 10 als Feuchtigkeitsbarriere, insbesondere Gelatine und/oder Sauerstoffbarriere, insbesondere eine entsprechend dotierte Gelatine, versehen ist. Optional ist auf der Innenseite ferner ein Siegelmedium und/oder auf der Außenseite möglicherweise ein Dispersionslack 11 vorgesehen. Als Feuchtigkeitsbarriere eignen sich auch PE, PLA, SIOx und/oder eine Plasmabeschichtung.In Figure 2 is a detailed schematic view of the in Figure 1 illustrated portion capsule 1, which illustrates the layer structure of the portion 8. The partial area 8 consists of a dimensionally stable fiber material 10, formed from compressed and / or glued cellulose fibers, which is provided on its inside with a coating 10 as a moisture barrier, in particular gelatin and / or oxygen barrier, in particular a correspondingly doped gelatin. Optionally, a sealing medium is also provided on the inside and / or possibly a dispersion lacquer 11 on the outside. PE, PLA, SIOx and / or a plasma coating are also suitable as a moisture barrier.
