Der Bodenteil weist zumindest eine Durchströmöffnung für das Extrakt auf über die es einem weiteren Gehäuseteil zugeleitet wird der der Durchströmöffnung zugewandt einen rohrförmigen Einlasskanal, sowie Strömungskanäle und eine Abgabeöffnung aufweist. Dieser Einlasskanal ist mit einer Dichtungsmembrane, zur Vermeidung des Eindringens von Verunreinigungen in den Innenraum der Kaffeekapsel überdeckt und die bei einem entsprechenden Mediumsdruck einen Durchlass für das Extrakt freigibt.From the document WO 2008/011913 A1 is a, provided for single use coffee capsule for receiving a predetermined quantity ground coffee known, which consists of three housing parts with an approximately cylindrical, filled with coffee powder, a bottom part having housing middle part is sealed with a, an inflow opening for an extraction fluid having the cover part. The bottom part has at least one through-flow opening for the extract via which it is fed to a further housing part which faces the flow-through opening, has a tubular inlet channel, as well as flow channels and a discharge opening. This inlet channel is covered with a sealing membrane, to prevent the ingress of contaminants into the interior of the coffee capsule and releases a passage for the extract at a corresponding medium pressure.

Aus einem weiteren Dokument, DE 26 02 832 A1 , ist eine Kapsel für die Aufnahme einer Quantität eines für eine Getränkezubereitung vorgesehenen Produktes durch Zuführen eines fluidischen Mediums in die Kapsel bekannt. Diese ist als ein kegelstumpfförmiges Gehäuse mit einstückig angeformten Boden ausgebildet der eine Ausströmöffnung aufweist. Im Innenraum der Kapsel ist der Ausströmöffnung eine verformbare Dichtungsscheibe vorgeordnet die an der Gehäusewand dichtend anliegt. Nach der Befüllung der Kapsel mit dem Produkt wird das Gehäuse mit einer Deckscheibe versiegelt. Bei Anwendung der Kapsel wird durch mechanische Durchtrennung der Deckscheibe eine Einströmöffnung zur Zuführung des Mediums in den Gehäuseinnenraum geschaffen. Wird ein von den elastischen Eigenschaften der Dichtungsscheibe abhängiger Innendruck in dem Gehäuse erreicht erfolgt, bedingt durch Stützmittel auf welche die Dichtscheibe gegen über dem Bodenteil aufgelagert ist, eine schüsselartige Verformung der Dichtscheibe wodurch ein Ringspalt längs der Gehäusewand frei gegeben wird durch den das Getränk der Ausströmöffnung zugeleitet wird.From another document, DE 26 02 832 A1 , a capsule is known for receiving a quantity of a product intended for a beverage preparation by supplying a fluidic medium into the capsule.

Eine Maßtoleranz zwischen einem Innendurchmesser 28 des zylindrischen Mantelabschnitts 8 und eines Außendurchmessers 29 des zylindrischen Ansatzes 26 ist für einen Haltesitz ausgelegt um den Deckelteil 4 nach einem Gebrauch manuell abnehmen zu können.A dimensional tolerance between an inner diameter 28 of the cylindrical shell portion 8 and an outer diameter 29 of the cylindrical projection 26 is designed for a retaining seat in order to be able to remove the cover part 4 manually after use.

Konzentrisch zur Mittelachse 25 ist im Deckelteil eine durch eine Bohrung 30 gebildete Auslassöffnung 31 vorgesehen. Diese Auslassöffnung 31 ist durch eine Membrane 32 aus einem elastomeren Werkstoff, z.B. Gummi, Kautschuk, Festsilikon etc., bevorzugt Flüssigsilikon (LSR), überdeckt.Concentric with the central axis 25, an outlet opening 31 formed by a bore 30 is provided in the cover part. This outlet opening 31 is defined by a membrane 32 of an elastomeric material, e.g. Rubber, rubber, solid silicone, etc., preferably liquid silicone (LSR), covered.

Diese ist mit dem Deckelteil 4 in einem Aufspritzverfahren durch Ummantelung eines Randbereiches 33 der Auslassöffnung 31 fest verbunden ist. Für eine dauerhafte Verbindung der Membrane 32 mit dem Deckelteil 4 sind in dem Randbereich 33 über einen Umfang der Auslassöffnung 31 verteilt Ankerbohrungen 34 vorgesehen wodurch auch die Haltbarkeit auch bei dem im Gehäuseinnenraum 12 auftretenden, und für eine gute Qualität des Kaffeegetränks maßgebenden, entsprechenden hohen Innendruckes, z.B. zwischen 8 bar und 16 bar gegeben ist.This is firmly connected to the cover part 4 in a spray-on process by sheathing a peripheral region 33 of the outlet opening 31. For a permanent connection of the membrane 32 with the cover part 4 anchor bores 34 are provided in the edge region 33 distributed over a circumference of the outlet opening 31 whereby the durability even in the housing interior 12 occurring, and for a good quality of the coffee beverage authoritative, corresponding high internal pressure , eg between 8 bar and 16 bar is given.

Die Membrane 32 ist mit einer Mehrzahl über die Kreisfläche der Auslassöffnung 31 verteilten Perforationen 35 versehen.The membrane 32 is provided with a plurality of perforations 35 distributed over the circular area of the outlet opening 31.

Anzahl und Form der Perforationen 35 gewährleisten in Verbindung mit den vorgegebenen elastischen Eigenschaften des Materials, insbesondere der Shore- Härte, aber auch der Dicke der Membrane 32 einen Druckaufbau in dem Gehäuseinnenraum 12 nach einem Zuführen des Extraktionsfluids 20 durch die Einströmöffnungen 18 des Bodenteils 7 bevor es zu einer Abgabe des Extraktes - Pfeile 21 - nach einer entsprechenden, druckbedingten Erweiterung der Perforationen 35 der Membrane 32 kommt. Dieser Vorgang ist für die Qualität des bereiteten Getränks maßgeblich.Number and shape of the perforations 35 ensure, in conjunction with the predetermined elastic properties of the material, in particular the Shore hardness, but also the thickness of the membrane 32 a pressure build-up in the housing interior 12 before feeding the extraction fluid 20 through the inlet openings 18 of the bottom part 7 before there is a release of the extract - arrows 21 - after a corresponding, pressure-related expansion of the perforations 35 of the membrane 32 comes. This process is decisive for the quality of the prepared drink.

Die Perforationen 35 in der Membran 32 können beispielsweise Bohrungen, Schlitze, Kreuzschlitze sein, die bei der Druckbeaufschlagung mit dem Extrakt zur Erzielung der Durchlässigkeit erweitert werden und nach Beendigung der Druckbeaufschlagung, aufgrund der elastischen Verformbarkeit des Materials der Membrane 32, ihre ursprüngliche Ausgangsgröße, die eine Rückhaltewirkung gewährleistet, wieder einnehmen.The perforations 35 in the membrane 32 may be, for example, bores, slots, cross-slits, which are expanded upon pressurization with the extract to achieve the permeability and after completion of the pressurization, due to the elastic deformability of the material of the membrane 32, their original output ensures a retention effect, take again.

In den Fig. 4 und 5 ist eine weitere und gegebenenfalls für sich eigenständige Ausführungsform der Kaffeekapsel 1 gezeigt, wobei wiederum für gleiche Teile gleiche Bezugszeichen bzw. Bauteilbezeichnungen wie in den vorangegangenen Fig. 1 bis 3 verwendet werden. Um unnötige Wiederholungen zu vermeiden, wird auf die detaillierte Beschreibung in den vorangegangenen Fig. 1 bis 3 hingewiesen bzw. Bezug genommen.In the 4 and 5 is a further and possibly independent embodiment of the coffee capsule 1 is shown, again for like parts, the same reference numerals or component names as in the preceding Fig. 1 to 3 be used. In order to avoid unnecessary repetition, the detailed description in the previous ones will be used Fig. 1 to 3 referred or referred.

Diese weitere Ausführungsform der Kaffeekapsel 1 betrifft den Bodenteil 7 der Kaffeekapsel 1 bei ansonst gleicher Ausführungsform des Gehäuseteils 3 und des Deckelteils 4, wie bereits in den vorhergehenden Fig. 1 bis 3 beschrieben.This further embodiment of the coffee capsule 1 relates to the bottom part 7 of the coffee capsule 1 with otherwise the same embodiment of the housing part 3 and the cover part 4, as already in the preceding Fig. 1 to 3 described.

Der Bodenteil 7 weist konzentrisch zu der Mittelachse 25 den in der Ebene 13, die senkrecht zu der Mittelachse 25 gerichtet ist, den ringförmigen Randbereich 10 auf. In Richtung der Mittelachse 25 schließt an den Randbereich 10 ein, eine durch eine Umformung in Richtung des Gehäuseinnenraumes 12 gebildete Nut 35 in einem ringförmigen Umformbereich 36 an.The bottom part 7 has concentric with the central axis 25 in the plane 13, which is directed perpendicular to the central axis 25, the annular edge portion 10. In the direction of the center axis 25, the edge region 10 adjoins a groove 35 formed by a deformation in the direction of the housing interior 12 in an annular deformation region 36.

Damit wird der bereits vorhergehend beschriebene Freiraum 15 gebildet für die nicht weiter dargestellten Piercingwerkzeuge für die Anwendung von gängigen Einmalkapseln. Diese Piercingwerkzeuge für die durchzuführenden Lochungen von Einmalkapseln dringen bei der Anwendung somit durch die gezeigte Ausbildung des Bodenteils 7 in den Freiraum 15, insbesondere Nut 37 ein und kommt es damit weder an den Piercingwerkzeugen noch am Bodenteil 7 zu Beschädigungen.Thus, the previously described free space 15 is formed for the piercing tools not shown for the use of common disposable capsules. These piercing tools for the perforations carried out by disposable capsules penetrate in the application thus by the training of the bottom part 7 shown in the free space 15, in particular groove 37 and thus it comes neither to the Piercingwerkzeugen still on the bottom part 7 to damage.

Diese ringförmig umlaufende Nut 37 weist gegenüber der Ebene 13 beispielsweise eine Tiefe 38 von ca. 2,0 mm bis 2,5 mm auf, und einen Mitteldurchmesser 39 von ca. 12,0 mm bis 13,0 mm, bei beispielsweise einem Außendurchmesser 40 des Bodenteils 7 von etwa 22,0 mm bis 26,0 mm.This annular circumferential groove 37 has, for example, a depth 38 of approximately 2.0 mm to 2.5 mm with respect to the plane 13, and an average diameter 39 of approximately 12.0 mm to 13.0 mm, for example an outer diameter 40 of the bottom part 7 of about 22.0 mm to 26.0 mm.

Der Zentrumsbereich 11 des Bodenteils 7 ist mit einer napfförmigen Ausformung in einer zum Gehäuseinnenraum 12 entgegen gesetzten Richtung versehen, wobei eine Höhe 42 der napfförmigen Ausformung 41 größer ist als die Tiefe 38 der Nut 37.The center region 11 of the bottom part 7 is provided with a cup-shaped formation in a direction opposite the housing interior 12 opposite direction, wherein a height 42 of the cup-shaped formation 41 is greater than the depth 38 of the groove 37th

Damit wird ein ebenflächiger Abschluss des Gehäuseteils 3 als Kreisfläche in einer die Ebene 13 entgegen den Gehäuseinnenraum 12 überragenden Distanz 43 erreicht, die der Differenz aus der Höhe 42 abzüglich der Tiefe 38 der Nut 37 entspricht.Thus, a planar end of the housing part 3 is achieved as a circular area in a plane 13 against the housing interior 12 superior distance 43, which corresponds to the difference from the height 42 minus the depth 38 of the groove 37.

Durch diese Ausformung 41 und entsprechend einer vorgesehenen Höhe 42 wird eine Erweiterung des Aufnahmevolumens für die Substanz 2 erreicht, ohne die grundsätzlichen Abmessungen des Gehäusemantels 6 zu verändern.By this formation 41 and corresponding to a designated height 42, an extension of the receiving volume for the substance 2 is achieved, without changing the basic dimensions of the housing shell 6.

Weiter ist der Fig. 4 zu entnehmen, dass für den Einsatz der Kaffeekapsel 1 in Getränkeautomaten und deren Funktion der Deckelteil 4 in einem ringförmigen Überstand 44 mit dem dieser den Außendurchmesser 23 des Gehäuseteils 3 überragt bei Anwirkung einer radialen Kraft - gemäß Pfeil 45 - eine federelastische Verformung - gemäß Doppelpfeile 46 - zulässt.Next is the Fig. 4 It can be seen that for the use of the coffee capsule 1 in beverage vending machines and their function, the cover part 4 in an annular projection 44 with this the outside diameter 23 of the housing part 3 surmounted by the application of a radial force - according to arrow 45 - a resilient deformation - according to double arrows 46th - allows.

Wie nun weiter der Fig. 5 zu entnehmen, weist der Bodenteil 7 im ringförmigen Randbereich 10 eine Vielzahl von um die Mittelachse 25 radial angeordneter Bohrungen 47 auf, die als Einströmöffnungen 18 für die Zufuhr des Extraktionsfluid - Pfeile 19 - dienen. Weiters sind derartige Bohrungen 47 im ebenflächigen Zentrumsbereich 11 des Bodenteils 7 vorgesehen.Now how the next Fig. 5 can be seen, the bottom part 7 in the annular edge portion 10 a plurality of about the central axis 25 radially arranged bores 47, which serve as inflow openings 18 for the supply of the extraction fluid - arrows 19. Furthermore, such holes 47 are provided in the planar center region 11 of the bottom part 7.

Durch diese Verteilung der Bohrung 47 in den ringförmigen Randbereich 10 und dem Zentrumsbereich 11 wird der in der Kaffeekapsel 1 befindlichen Substanz 2 sehr rasch und auf das gesamte Füllvolumen gleichmäßig einwirkende Extraktionsfluid - Pfeile 19 - zugeführt, wodurch eine sehr ausgewogene Qualität an den zu erzeugenden Extrakts erreicht wird.By this distribution of the bore 47 in the annular edge region 10 and the central region 11 of the substance 2 located in the coffee capsule 1 is supplied very rapidly and uniformly acting on the entire filling volume extraction fluid - arrows 19 - whereby a very balanced quality of the extract to be produced is reached.
