Description

Die vorliegende Erfindung betrifft eine Kapsel nach Anspruch 1.The present invention relates to a capsule according to claim 1.

Im Stand der Technik sind eine Vielzahl von unterschiedlichen Portionsverpackungen und Systemen zur Herstellung von flüssigen Lebensmitteln bekannt. Insbesondere Kapseln werden häufig zur Zubereitung von unterschiedlichen Getränken, allen voran Kaffee oder Tee, allerdings auch lösliche Getränke, im Heimgebrauch eingesetzt. Üblicherweise umfassen solche Kapseln, die als Einwegprodukte konzipiert sind, einen Kapselkörper, der einen Hohlraum zur Aufnahme von Getränkezutaten bildet, sowie einen den Hohlraum abschliessenden Deckel. Bei den Getränkezutaten handelt es sich in vielen Fällen um geröstetes und gemahlenes Kaffeepulver, teilweise aber auch um getrocknete Teeblätter. Allerdings kommen auch lösliche Produkte im Allgemeinen oder Konzentrate in Frage. Zur Getränkezubereitung wird unter Druck stehendes Wasser durch die Kapsel geleitet, wodurch es zu einer Extraktion bzw. zu einem Auflösen des in der Kapsel enthaltenen Materiales kommt.A large number of different portion packs and systems for the production of liquid foods are known in the prior art. In particular, capsules are often used at home to prepare different beverages, above all coffee or tea, but also soluble beverages. Such capsules, which are designed as single-use products, usually comprise a capsule body, which forms a cavity for receiving beverage ingredients, and a lid closing off the cavity. In many cases, the beverage ingredients are roasted and ground coffee powder, but sometimes also dried tea leaves. However, soluble products in general or concentrates can also be used. To prepare the beverage, pressurized water is passed through the capsule, causing the material contained in the capsule to be extracted or dissolved.

So beschreibt die EP 1 440 911 A1 eine Kapsel, welche zur Aufnahme von verschiedenen Getränkezutaten geeignet ist. Die besagte Kapsel besteht aus im Wesentlichen luft- und wasserundurchlässigen Materialien. Die Kapsel umfasst einen Kapselkörper, der eine Kammer für die Getränkezutaten bildet. In der Kammer ist ein Innenteil lagestabil gehalten, welches einen Auslaufstutzen für ein in der Kammer erzeugtes Getränk aufweist. Im Lieferzustand sind sowohl die Kammer als auch der Auslaufstutzen mit einem den Kapselkörper abdeckenden Deckel verschlossen. Zur Zubereitung eines Getränkeproduktes wird der Deckel gleichzeitig an zwei Stellen penetriert; einerseits zum Einleiten von unter Druck stehendem Wasser in die Kammer, andererseits um den Auslaufstutzen zu öffnen.That's how she describes it EP 1 440 911 A1 a capsule which is suitable for receiving various beverage ingredients. Said capsule consists of essentially air and water impermeable materials. The capsule includes a capsule body that forms a compartment for the beverage ingredients. An inner part is held in a stable position in the chamber and has an outlet nozzle for a beverage produced in the chamber. When delivered, both the chamber and the outlet nozzle are closed with a lid that covers the capsule body. To prepare a beverage product, the lid is penetrated in two places at the same time; on the one hand to introduce pressurized water into the chamber, on the other hand to open the outlet nozzle.

Bei der besagten Kapsel ist es für die erfolgreiche Herstellung eines Getränkeproduktes zentral, dass der den Kapselkörper abdeckende Deckel fest mit den Stirnseiten des Kapselkörpers und des Auslaufstutzens verbunden ist. Weist diese Verbindung Schwachstellen auf, kann unter Druck stehendes Wasser potenziell unkontrolliert aus der Kapsel austreten. Dies kann insbesondere bei einer Extraktion des Kapselinhaltes gravierend sein, da eine in der Kapsel vorliegende Suspension von Getränkezutaten, beispielsweise von Kaffeepulver, die Kapsel unkontrolliert verlassen kann. Die Folge davon kann eine Verschmutzung der Getränkeherstellungsvorrichtung oder eine Verunreinigung des fertigen Getränkes sein.In the case of said capsule, it is central to the successful production of a beverage product that the lid covering the capsule body is firmly connected to the end faces of the capsule body and the outlet nozzle. If there are any weak points in this connection, pressurized water can potentially leak out of the capsule in an uncontrolled manner. This can be particularly serious when the capsule contents are extracted, since a suspension of beverage ingredients, for example coffee powder, present in the capsule can leave the capsule in an uncontrolled manner. The consequence of this can be contamination of the beverage production device or contamination of the finished beverage.

Es ist daher eine Aufgabe der vorliegenden Erfindung, die Nachteile im Stand der Technik zu überwinden. Insbesondere ist es eine Aufgabe der vorliegenden Erfindung, eine Kapsel der oben genannten Art zu schaffen, bei der die Zuverlässigkeit der Anbringung des Deckels am Kapselkörper und am Auslaufstutzen verbessert ist. Darüber hinaus soll die besagte Kapsel gegenüber dem Stand der Technik vielseitiger einsetzbar und einfacher herstellbar sein.It is therefore an object of the present invention to overcome the disadvantages of the prior art. In particular, it is an object of the present invention to provide a capsule of the type mentioned above, in which the reliability of the attachment of the lid to the capsule body and the spout is improved. In addition, said capsule should be more versatile and easier to produce than the prior art.

Diese Aufgaben werden durch eine Kapsel gelöst, welche die Merkmale in Anspruch 1 aufweist.These objects are achieved by a capsule having the features of claim 1.

Eine derartige Kapsel umfasst einen vorzugweise rotationssymmetrisch ausgebildeten Kapselkörper, der einen Hohlraum mit einer Öffnung zur Aufnahme mindestens einer Substanz zur Zubereitung eines flüssigen Lebensmittels bildet. Zur Durchleitung einer Flüssigkeit durch die Kapsel ist innerhalb des Hohlraums ein Auslaufstutzen angeordnet, der in Richtung der Öffnung gerichtet ist. Der Auslaufstutzen ist insbesondere mit einem die Öffnung abdeckenden Deckel verschlossen. Der Kapselkörper und der Auslaufstutzen sind einstückig ausgebildet.Such a capsule comprises a preferably rotationally symmetrical capsule body, which forms a cavity with an opening for receiving at least one substance for preparing a liquid foodstuff. For the passage of a liquid through the capsule, an outlet nozzle is arranged inside the cavity, which is directed in the direction of the opening. The outlet nozzle is in particular closed with a cover covering the opening. The capsule body and the outlet nozzle are designed in one piece.

Bei dieser Ausgestaltung der Kapsel muss der Auslaufstutzen nicht als separates Teil in den Hohlraum des Kapselkörpers eingesetzt werden. Da Kapselkörper und Auslaufstutzen einstückig ausgebildet sind, ist die präzise relative Positionierung Auslaufstutzens im Kapselkörper gewährleistet. Beim Anbringen des Deckels an der Kapsel kann damit leichter erreicht werden, dass dieser sowohl die Öffnung des Kapselkörpers als auch den Übergang zum Auslaufstutzen, bzw. gegebenenfalls den Auslaufstutzen selbst, dichtend abschliesst. Die Gefahr eines Auslaufens des Kapselinhalts vor, während oder nach der Getränkezubereitung ist damit erheblich verringert.With this configuration of the capsule, the outlet nozzle does not have to be inserted as a separate part into the cavity of the capsule body. Since the capsule body and outlet nozzle are designed in one piece, the precise relative positioning of the outlet nozzle in the capsule body is ensured. When attaching the cover to the capsule, it can thus be achieved more easily that it seals off both the opening of the capsule body and the transition to the outlet connection piece, or possibly the outlet connection piece itself. The risk of the capsule contents escaping before, during or after the beverage preparation is thus considerably reduced.

Zur Durchleitung einer Flüssigkeit durch die Kapsel kann innerhalb des Hohlraums ein Einlauf, insbesondere eine Einlaufrinne, angeordnet und in Richtung der Öffnung gerichtet sein. Allerdings ist es auch möglich, den Einlauf, gegebenenfalls zusätzlich, als Einlaufstutzen auszuführen. Das Vorhandensein eines Einlaufes erlaubt es, das Einleiten einer Flüssigkeit in den Hohlraum des Kapselkörpers besser zu kontrollieren. Mit einer Einlaufrinne kann beispielsweise die Verteilung der Flüssigkeit über den gesamten Kapselinhalt besser erreicht werden. Durch das Vorhandensein eines Einlaufstutzens ist es einfacher, eine dichte Fluidverbindung zwischen einer Getränkeherstellungsvorrichtung und der Kapsel herzustellen.To conduct a liquid through the capsule, an inlet, in particular an inlet channel, can be arranged inside the cavity and directed in the direction of the opening. However, it is also possible to design the inlet, optionally additionally, as an inlet nozzle. The presence of an enema allows better control of the introduction of a liquid into the cavity of the capsule body. With an inlet channel, for example, the liquid can be better distributed over the entire contents of the capsule. The presence of an inlet nozzle makes it easier to establish a tight fluid connection between a beverage production device and the capsule.

Der Einlauf kann mit dem gleichzeitig die Öffnung abdeckenden Deckel verschlossen sein. Bei einer derartigen Ausführung sind sowohl der Einlauf- als auch der Auslaufstutzen auf derselben Seite der Kapsel angeordnet. Dies hat den Vorteil, dass zur Durchleitung einer Flüssigkeit durch die Kapsel gegebenenfalls nur der die Öffnung des Kapselkörpers abdeckende Deckel durchbrochen werden muss. Eine oftmals schwierige Penetration des Kapselkörpers, die gegebenen Falls auch das Anbringen von Sollbruchstellen erfordert, entfällt.The inlet can be closed with the cover, which at the same time covers the opening. In such an embodiment, both the inlet and the outlet nozzle are arranged on the same side of the capsule. This has the advantage that in order to conduct a liquid through the capsule, only the cover covering the opening of the capsule body may have to be broken through. An often difficult penetration of the capsule body, which may also require the provision of predetermined breaking points, is no longer necessary.

Die Stirnseiten des Kapselkörpers und des Auslaufstutzens, und gegebenenfalls auch des Einlaufs, können im Wesentlichen in einer Ebene angeordnet sein. Damit kann das Anbringen des Deckels am Kapselkörper durch herkömmliche Verfahren erfolgen, wie sie zum Versiegeln von Lebensmittelpackungen gebräuchlich sind. Der Auslaufstutzen kann zentral und der Einlauf in einem Randbereich des Kapselkörpers angeordnet sein. Dies ist insbesondere vorteilhaft, da sich in der Praxis eine Extraktion beziehungsweise ein Auflösen des Kapselinhaltes von aussen nach innen als vorteilhaft erwiesen hat.The end faces of the capsule body and the outlet nozzle, and possibly also the inlet, can be arranged essentially in one plane. Thus, the attachment of the lid on the capsule body can be done by conventional methods, such as those for Sealing of food packages are common. The outlet nozzle can be arranged centrally and the inlet can be arranged in an edge area of the capsule body. This is particularly advantageous since in practice extraction or dissolution of the capsule contents from the outside inwards has proven to be advantageous.

Der Kapselkörper bildet einen Übergangsbereich und der Hohlraum steht über den Übergangsbereich mit dem Auslaufstutzen in Fluidverbindung. Durch die Unterteilung der Kapsel in den Hohlraum und den Übergangsbereich ist es möglich, im Inneren der Kapsel zwei Kompartimente zu schaffen. Dies ist insbesondere vorteilhaft, wenn der Kapselinhalt filtriert werden muss. Darüber hinaus können die beiden Kompartimente für weitere Funktionen verwendet werden. So kann beispielsweise der durch den Kapselkörper gebildete Hohlraum die eigentliche Speicherfunktion der Kapsel wahrnehmen, während im Übergangsbereich weitere Prozesse wie das Aufschäumen des zubereiteten flüssigen Lebensmittels durch Einbringen von Luft oder das Vermischen mehrerer Zutaten ablaufen.The capsule body forms a transition area and the cavity is in fluid communication with the outlet nozzle via the transition area. By dividing the capsule into the cavity and the transition area, it is possible to create two compartments inside the capsule. This is particularly advantageous when the capsule contents have to be filtered. In addition, the two compartments can be used for other functions. For example, the cavity formed by the capsule body can perform the actual storage function of the capsule, while other processes such as the foaming of the prepared liquid foodstuff through the introduction of air or the mixing of several ingredients take place in the transition area.

Der Übergangsbereich ist auf einer der Öffnung des Kapselkörpers abgewandten Seite mit einer Abdeckung, insbesondere mit einem Abdeckelement oder einer Abdeckfolie, abgedeckt. Dadurch ist es möglich, die Kapsel hermetisch zu verschliessen. Ferner können durch das Abdeckelement verschiedene Funktionen, wie beispielsweise eine Sieb- oder Filterfunktion, in den Übergansbereich implementiert werden. Darüber hinaus ist es auch möglich, dass das Abdeckelement mit einem Einlaufstutzen versehen ist, oder die Abdeckfolie zum Einleiten einer Flüssigkeit penetriert wird. Dadurch wird eine modulare Ausführung der Kapsel ermöglicht, bei der das Einleiten und Abgeben von Flüssigkeit wahlweise entweder einseitig oder zweiseitig erfolgt.The transition area is covered with a cover, in particular with a cover element or a cover film, on a side facing away from the opening of the capsule body. This makes it possible to hermetically seal the capsule. Furthermore, various functions, such as a sieve or filter function, can be implemented in the transition area by the covering element. In addition, it is also possible for the cover element to be provided with an inlet nozzle, or for the cover film to be penetrated in order to introduce a liquid. This enables a modular design of the capsule, in which the introduction and dispensing of liquid takes place either on one side or on two sides.

Die Abdeckung kann durch Kleben, Ultraschallschweissen oder Heisssiegeln mit dem Kapselkörper verbunden sein. Dabei handelt es sich um bewährte Verfahren, welche eine zuverlässige Anbringung der Abdeckung auf dem Kapselkörper ermöglichen. Die Abdeckung kann als Abdeckelement, insbesondere als Stopfen, ausgeführt und kraft- und/oder formschlüssig, insbesondere über eine Rastverbindung, mit dem Kapselkörper verbunden sein. Diese Ausgestaltungen ermöglichen eine sehr einfache Montage der Kapsel. Wie bereits angedeutet, kann im Übergangsbereich ein Filterelement angeordnet sein. Dies ermöglicht es, das hergestellte Getränk bei der Zubereitung zu filtrieren. Dies ist insbesondere bei der Zubereitung von Kaffee vorteilhaft. Allerdings wäre auch die Herstellung von Tee aus getrockneten Teeblättern denkbar. Das Filterelement kann scheibenförmig und/oder aus Filterpapier hergestellt sein.The cover can be connected to the capsule body by gluing, ultrasonic welding or heat sealing. These are tried and tested methods that enable the cover to be reliably attached to the capsule body. The cover can be designed as a cover element, in particular as a plug, and can be connected to the capsule body in a non-positive and/or positive manner, in particular via a snap-in connection. These configurations enable the capsule to be assembled very easily. As already indicated, a filter element can be arranged in the transition area. This makes it possible to filter the drink produced during preparation. This is particularly advantageous when preparing coffee. However, the production of tea from dried tea leaves would also be conceivable. The filter element can be disc-shaped and/or made of filter paper.

Der Kapselkörper und die Abdeckung bilden im Übergangsbereich einen ringförmigen Fluidkanal. Ein solcher ermöglicht es, dass ein zubereitetes flüssiges Lebensmittel über den gesamten Umfang des Auslaufstutzens in diesen eingeleitet werden kann.The capsule body and the cover form an annular fluid channel in the transition area. Such a device makes it possible for a prepared liquid foodstuff to be introduced into the outlet connection piece over the entire circumference of the latter.

Der Kapselkörper und der Auslaufstutzen, und gegebenenfalls auch die Abdeckung, können durch ein Spritzguss- oder Tiefziehverfahren gefertigt sein. Die Anwendung eines Spritzgussverfahrens gewährt eine grosse Flexibilität in Bezug auf die Ausgestaltung der Form des Kapselkörpers. Diese ist zwar bei einem Tiefziehverfahren eingeschränkt, jedoch ist es damit möglich, besonders sauerstoff- und/oder aromadichte Kapseln herzustellen. Allerdings ist Sauerstoff- und/oder Aromadichtigkeit nicht auf durch ein Tiefziehverfahren hergestellte Kapseln beschränkt.The capsule body and the outlet nozzle, and possibly also the cover, can be manufactured using an injection molding or deep-drawing process. The use of an injection molding process allows great flexibility with regard to the design of the shape of the capsule body. Although this is limited in a deep-drawing process, it is possible to produce particularly oxygen- and/or aroma-tight capsules. However, oxygen and/or aroma tightness is not limited to capsules produced by a deep-drawing process.

Ist die Kapsel sauerstoffdicht ausgebildet, wird ein Eindringen von Sauerstoff in die Kapsel während der Lagerung einer darin enthaltenen Ausgangssubstanz im Wesentlichen vermieden. Dadurch kann ein Altern der Ausgangssubstanz, beispielsweise von Kaffeepulver, durch Oxidation vermieden werden. Eine sauerstoffdichte Kapsel ist in der Regel auch aromadicht. Entsprechend wird ein Austreten von in der Ausgangssubstanz enthaltenen Aromastoffen während der Lagerung derselben innerhalb der Kapsel im Wesentlichen verhindert. Sauerstoff- beziehungsweise Aromadichtigkeit ist erforderlich, um insbesondere bei Kaffee eine Mindesthaltbarkeit von 12 Monaten, vorzugsweise 18 Monaten, zu erreichen. Entsprechend wird im vorliegenden Zusammenhang unter einer sauerstoff- und/oder aromadichten Kapsel eine Kapsel verstanden, in welcher Kaffeepulver für eine Dauer von mindestens 12 Monaten, vorzugsweise 18 Monaten, bei Raumtemperatur an Atmosphärenluft aufbewahrbar ist, ohne dass es zu einer Veränderung des Kaffeepulvers kommen würde, welche die Qualität eines daraus hergestellten Kaffeegetränkes beeinträchtigt.If the capsule is designed to be oxygen-tight, penetration of oxygen into the capsule during storage of a starting substance contained therein is essentially avoided. As a result, aging of the starting substance, for example coffee powder, can be avoided by oxidation. An oxygen-tight capsule is usually also aroma-tight. Accordingly, flavoring substances contained in the starting substance are essentially prevented from escaping during storage of the same within the capsule. Oxygen or aroma impermeability is required in order to achieve a minimum shelf life of 12 months, preferably 18 months, particularly in the case of coffee. Accordingly, in the present context, an oxygen- and/or aroma-tight capsule is understood to mean a capsule in which coffee powder can be stored at room temperature in atmospheric air for a period of at least 12 months, preferably 18 months, without the coffee powder changing , which impairs the quality of a coffee beverage made from it.

Wird eine sauerstoff- und/oder aromadichte Kapsel mit einem Tiefziehverfahren hergestellt, so kann das dazu verwendete Folienmaterial eine OTR (Oxygen Transmission Rate) von weniger als 5, vorzugsweise weniger als 2 haben. Die OTR gibt an, welche Menge an Sauerstoff pro Flächen- und Zeiteinheit durch eine Folie diffundiert, in der Einheit: cm3/m2/Tag/0.21 bar.If an oxygen and/or aroma-tight capsule is produced using a deep-drawing process, the film material used for this purpose can have an OTR (oxygen transmission rate) of less than 5, preferably less than 2. The OTR indicates the amount of oxygen per unit area and time that diffuses through a foil, in the unit: cm 3 /m 2 /day/0.21 bar.

Allerdings kann auch der fertige sauerstoff- und/oder aromadichte Kapselkörper, bzw. die gesamte Kapsel (inklusive Abdeckung und Deckel), eine OTR (Oxygen Transmission Rate) von weniger als 5, vorzugsweise weniger als 2, haben. Dies gilt losgelöst vom angewendeten Herstellungsverfahren.However, the finished oxygen- and/or aroma-tight capsule body, or the entire capsule (including cover and lid), can have an OTR (oxygen transmission rate) of less than 5, preferably less than 2. This applies regardless of the manufacturing process used.

Der Kapselkörper und der Auslaufstutzen, und gegebenenfalls auch die Abdeckung, können aus einem ein- oder mehrschichtigen Kunststoff, vorzugsweise enthaltend Polypropylen, gefertigt sein. Dabei handelt es sich um ein Material, das sich für die Herstellung von Getränkeverpackungen bewährt hat. Darüber hinaus lässt sich Polypropylen hervorragend durch Spritzguss verarbeiten.The capsule body and the outlet nozzle, and optionally also the cover, can be made of a single-layer or multi-layer plastic, preferably containing polypropylene. This is a material that has proven itself for the manufacture of beverage packaging. In addition, polypropylene can be excellently processed by injection molding.

In Figur 1 ist ein Kapselkörper 2 für eine erfindungsgemässe Kapsel 1 (vgl. Fig. 9) von seiner der Öffnung 4 mit dem Hohlraum 3 des Kapselkörpers 2 abgewandten Seite dargestellt. Zu erkennen ist der Übergangsbereich 10 welcher über mehrere Durchgänge 9, 9' mit dem Hohlraum 3 in Fluidverbindung steht. Figur 2 zeigt den Kapselkörper 2 gemäss Figur 1 aus einer anderen Perspektive. Zusätzlich ist auch eine Abdeckung 11 zu sehen, die hier als Abdeckelement in Form eines Stopfens ausgeführt ist. Die Figuren 3 und 4 zeigen ebenfalls den Kapselkörper 2 und das Abdeckelement 11. Allerdings ist diesmal das Abdeckelement 11 in den Übergangsbereich 10 des Kapselkörpers 2 eingesetzt.In figure 1 is a capsule body 2 for a capsule 1 according to the invention (cf. 9 ) shown from its side facing away from the opening 4 with the cavity 3 of the capsule body 2 . The transition area 10 can be seen, which is in fluid connection with the cavity 3 via a number of passages 9, 9'. figure 2 shows the capsule body 2 according to FIG figure 1 from a different perspective. In addition, a cover 11 can also be seen, which is designed here as a cover element in the form of a plug. The Figures 3 and 4 also show the capsule body 2 and the cover element 11. However, this time the cover element 11 is inserted into the transition region 10 of the capsule body 2.

Aus Figur 5 sind nähere Einzelheiten des durch den Kapselkörper 2 gebildeten Hohlraums 3 ersichtlich. So ist beim gezeigten Ausführungsbeispiel der Auslaufstutzen 5 zentral im Hohlraum 3 angeordnet. Des Weiteren enthält der Hohlraum 3 einen Einlauf 7, welcher im vorliegenden Fall als Einlaufrinne ausgeführt ist. In der gezeigten Draufsicht sind die Durchgänge 9, 9' ersichtlich, welche den Hohlraum mit dem Übergangsbereich 10 fluidmässig verbinden. Zudem ist erkennbar, dass die Einlaufrinne 7 über einen Spalt 14 mit dem restlichen Teil des Hohlraumes 3 verbunden ist.Out of figure 5 more details of the cavity 3 formed by the capsule body 2 can be seen. In the exemplary embodiment shown, the outlet connection 5 is arranged centrally in the cavity 3 . Furthermore, the cavity 3 contains an inlet 7, which in the present case is designed as an inlet channel. In the plan view shown, the passages 9, 9' can be seen, which fluidly connect the cavity with the transition region 10. It can also be seen that the inlet channel 7 is connected to the remaining part of the cavity 3 via a gap 14 .

Figur 6 zeigt den Kapselkörper gemäss den Figuren 1 bis 5 in Kombination mit dem Deckel 6, welcher zum Verschliessen der Öffnung 4 des Kapselkörpers 2 diesen vollständig abdeckt. figure 6 shows the capsule body according to the Figures 1 to 5 in combination with the cover 6, which completely covers the opening 4 of the capsule body 2 in order to close it.

Die Figur 7 zeigt eine zu Figur 2 analoge Abbildung. Es ist allerdings ersichtlich, dass zwischen dem Kapselkörper 2 und der Abdeckung 11 innerhalb des Übergangsbereiches 10 noch ein Filterelement 12 angeordnet ist.The figure 7 shows one to figure 2 analog figure. However, it can be seen that a filter element 12 is also arranged between the capsule body 2 and the cover 11 within the transition area 10 .

Aus Figur 8 sind nähere konstruktive Einzelheiten der Kapsel mit Filterelement 12 gemäss der Figur 7 besser ersichtlich. Es ist zu erkennen, dass sich der zentral innerhalb des Hohlraums 3 angeordnete Auslaufstutzen 5 aus einem Innenteil 15 und einem umlaufenden Kragen 16 zusammensetzt. Der umlaufende Kragen 16 ist dabei derart ausgestaltet, dass seine Stirnseite 8' mit der Stirnseite 8 des Kapselkörpers 2 in einer Ebene liegt. Das fluiddichte Anbringen eines Deckels 6 wird damit deutlich erleichtert. Zwischen dem Innenteil 15 und dem umlaufenden Kragen 16 ist ein Luftansaugloch 17 erkennbar. Das Luftansaugloch 17 dient dazu, im Rahmen der Zubereitung eines flüssigen Lebensmittels das Ansaugen von Luft in den Übergangsbereich 10 zu ermöglichen, wodurch ein Aufschäumen des durch den Auslaufstutzen 5 ausgegebenen flüssigen Lebensmittels erzielt werden kann. Ferner ist erkennbar, dass der Einlauf 7 als umlaufende Rinne ausgeführt ist, die über einen Spalt 14 mit dem restlichen Hohlraum des Kapselkörpers 2 in Verbindung steht. Der Kapselkörper 2 und die Abdeckung 11, welche hier als stopfenartiges Abdeckelement ausgebildet ist, bilden im Übergangsbereich 10 einen umlaufenden Fluidkanal 13. Dieser ist über eine Vielzahl von Durchgängen 9, 9' mit dem durch den Kapselkörper 2 gebildeten Hohlraum 3 verbunden.Out of figure 8 are more structural details of the capsule with filter element 12 according to figure 7 better visible. It can be seen that the outlet nozzle 5 arranged centrally within the cavity 3 is composed of an inner part 15 and a peripheral collar 16 . The peripheral collar 16 is designed in such a way that its end face 8 ′ lies in one plane with the end face 8 of the capsule body 2 . The fluid-tight attachment of a cover 6 is thus made significantly easier. An air intake hole 17 can be seen between the inner part 15 and the circumferential collar 16 . The air intake hole 17 serves to allow air to be sucked into the transition area 10 as part of the preparation of a liquid foodstuff, as a result of which foaming of the liquid foodstuff dispensed through the outlet nozzle 5 can be achieved. It can also be seen that the inlet 7 is designed as a circumferential channel which is connected to the remaining cavity of the capsule body 2 via a gap 14 . The capsule body 2 and the cover 11, which is designed here as a plug-like cover element, form a peripheral fluid channel 13 in the transition area 10. This is connected to the cavity 3 formed by the capsule body 2 via a large number of passages 9, 9'.

Die Figur 9 zeigt eine vollständig montierte Kapsel mit einem Kapselkörper wie vorgängig beschrieben. Zur besseren Übersichtlichkeit ist allerdings die Substanz zur Zubereitung eines flüssigen Lebensmittels innerhalb des Hohlraumes 3 weggelassen. Es ist zu erkennen, dass die Folie 6 mit den Stirnseiten 8, 8' des Kapselkörpers 2 und des Auslaufstutzens 5 in direktem Kontakt steht. Diese sind durch ein Ultraschallschweissverfahren miteinander verbunden. Alternativ wäre allerdings auch ein Heisssielverfahren anwendbar. In Figur 10 ist der durch einen Kreis markierte Teil der Figur 9 vergrössert dargestellt. Es sind nähere Einzelheiten zum Übergangsbereich 10 zu erkennen. Insbesondere ist ersichtlich, dass am Auslaufstutzen 5 ein Filterelement 12 angebracht ist, womit die in der Kapsel 1 enthaltene Substanz zur Zubereitung eines flüssigen Lebensmittels filtriert werden kann. Dies ist insbesondere bei der Herstellung von Kaffeegetränken aus gemahlenem Kaffeepulver vorteilhaft.The figure 9 shows a fully assembled capsule with a capsule body as previously described. However, for the sake of clarity, the substance for preparing a liquid foodstuff within the cavity 3 has been omitted. It can be seen that the foil 6 is in direct contact with the end faces 8 , 8 ′ of the capsule body 2 and the outlet nozzle 5 . These are connected to each other by an ultrasonic welding process. Alternatively, however, a hot sieve method could also be used. In figure 10 is the part marked by a circle figure 9 enlarged. More details about the transition area 10 can be seen. In particular, it can be seen that a filter element 12 is attached to the outlet connection piece 5, with which the substance contained in the capsule 1 for the preparation of a liquid foodstuff can be filtered. This is particularly advantageous when producing coffee beverages from ground coffee powder.
