Definitions

  • the present invention relates to a capsule according to the preamble of claim 1 and a method for producing such a capsule.
  • Capsules which in particular are only used once and are disposed of after use, are now widely used as portion packs for the preparation of, for example, coffee or tea in a device. The consumer no longer has to worry about dosing the correct amount of coffee, for example, and after the extraction process the capsule and its contents can be disposed of.
  • a capsule containing a substance for beverage production which has circular openings or elongated slots in the bottom.
  • a capsule for receiving a substance for beverage production is known, in which slots are arranged in the lid which can be opened by means of an opening device.
  • a capsule for receiving a substance for beverage production is known in which a base or a membrane of the capsule has areas of reduced thickness which can tear open during operation under the pressure of a supplied liquid.
  • a portion pack with a container, a base and a membrane is known, in which the base is perforated during operation by means of a piercing device for the supply of fluid.
  • a capsule which contains a substance such as coffee for the preparation of a beverage by brewing in a device.
  • This known capsule is usually made of aluminum sheet.
  • a plastic capsule which contains a substance for the production of a drink with a machine.
  • This known capsule is already less expensive to manufacture than aluminum, for example, and the energy consumption for its manufacture is also reduced compared to the known aluminum capsules.
  • this known capsule has the disadvantage that the plastic capsule is often not reliably penetrated in the machines for food production, as a result of which food of reduced quality may be produced if not enough liquid is conveyed through the capsule in accordance with the respective specifications.
  • a large overpressure arises in the device if the capsule is not penetrated and the supplied liquid cannot therefore be easily drained away, which may damage the device.
  • the overpressure can also pose a safety risk for the operator.
  • Another disadvantage of the known prior art is the need to include means for penetrating the capsule in the device, which is expensive.
  • a capsule is to be provided which can be used in a device for producing drinks without a penetration device.
  • the capsule according to the invention consists of a capsule body with a side wall and a bottom.
  • the capsule body is preferably designed to be rotationally symmetrical.
  • the capsule body is formed in one piece with the side wall and the bottom.
  • the capsule comprises a lid covering the capsule body to form a closed chamber which contains a substance for the preparation of a foodstuff.
  • the capsule body has at least one slot for the passage of a liquid through the capsule, which slot is formed essentially without material removal.
  • the slot in the capsule body is formed in a device for producing a food product before the capsule is used as intended.
  • the phrase “essentially without material removal” is understood to mean a non-cutting process with which the slot is formed, that is to say that essentially no material is removed from the capsule body during the formation of the slot. This can be achieved, for example, with a cutting method if a suitable cutting tool such as a knife is used.
  • the slot in the capsule body is formed before the intended use of the capsule in a device for the production of a foodstuff
  • the slot in the capsule body is formed during the production of the capsule body, after the production of the capsule body or after the filling and sealing of the capsule with a lid and the capsule with the slot in the capsule body is sold and stored.
  • a capsule in which a slot is formed during use in a device for the production of a food by a device of the device is therefore not a slot in the capsule body for the purposes of the present application, which is formed before the intended use of the capsule.
  • the slot can be produced with a knife and / or a laser.
  • the capsule is suitable for producing a foodstuff and in particular a drink in a device without a penetration device.
  • a “penetration device” is understood to mean a device with which the capsule can be penetrated and in particular pierced in the device when used as intended, so that liquid can be passed through the capsule.
  • rotationally symmetrical is understood to mean symmetry with respect to rotation about the longitudinal axis of the capsule by a discrete angle or also by any angle.
  • the formation of at least one slot in the capsule body has the advantage that if the penetration of the capsule body is possibly not reliable, the liquid can flow through the slot. This advantageously means that the creation of an overpressure in the device can be avoided, as a result of which the risk of damage to the device is reduced.
  • the arrangement of the slot in the capsule body makes it possible to achieve a more constant quality of the food produced, since at least a certain flow through the device is ensured.
  • the capsule according to the invention can be used in a device for producing a foodstuff without a penetration device.
  • coffee, tea and chocolate or any combination thereof can be used as the substance.
  • parameters such as the length of the slot, the wall thickness of the capsule body and the material of the capsule body or any combination of these parameters can advantageously influence the opening behavior of the slot when used as intended; For example, it is possible that the slot for the passage of a liquid only opens when a certain overpressure is reached in the device, which only exists if the capsule is not properly penetrated in the device; the slot can thus function as a safety valve and / or as a flow control device.
  • the opposite edges of the slot preferably touch at least in sections in a rest position.
  • the opposite edges of the slot preferably touch one another over at least 90% of a length l of the slot, in particular preferably to at least 95% and very particularly preferably to 100%.

  • a “rest position” is understood to mean the position of the slot in which, for example, no force is exerted on the capsule body by the device for producing a foodstuff.
  • a force can be, for example, a mechanical force to deform the capsule body, as a result of which the slot would move from the rest position.
  • it can also be, for example, a hydraulic force that arises when a liquid is fed into the capsule under pressure to extract the substance in the capsule, for example for brewing a coffee drink.
  • the configuration of the slot in such a way that the opposite edges touch at least in sections in the rest position has the advantage that the capsule is essentially closed and no substance can get out of the capsule body.
  • the slot can be opened from a rest position into an open position by means of an action of force.
  • the slot can be opened by means of a mechanical and / or hydraulic force.
  • an “open position” of the slot is understood to mean that position of the slot in which the opposite edges of the slot are spaced apart by the action of force for the passage of the liquid.
  • the slot can be opened by generating a pressure difference at least in the area of the slot between the chamber and the outside of the capsule body, in particular when the pressure difference is generated by means of a liquid that can be supplied under pressure.
  • the slot can be opened by means of a pressure difference between the outside of the capsule and the inside of the capsule formed by the chamber.
  • the slot can essentially be closed reversibly and essentially returns to the rest position.
  • the slot remains essentially in the open position after opening by means of the action of force in the open position and the supply of thermal energy.
  • the slot remains in the open position after the pressure difference has been removed.

The consumer no longer has to worry about dosing the correct amount of coffee, for example, and after the extraction process the capsule and its contents can be disposed of.

Aus der DE 27 52 733 ist eine Kapsel bekannt, die eine Substanz wie beispielsweise Kaffee für die Herstellung eines Getränks durch Aufbrühen in einer Vorrichtung enthält. Diese bekannte Kapsel wird üblicherweise aus Aluminiumblech hergestellt.From the DE 27 52 733 a capsule is known which contains a substance such as coffee for the preparation of a beverage by brewing in a device. This known capsule is usually made of aluminum sheet.

Die Verwendung von Aluminium als Material für die aus dem Stand der Technik bekannte Kapsel weist jedoch den Nachteil auf, dass Aluminium kostspielig ist und ein hoher Energieverbrauch bei der Aluminiumherstellung entsteht.However, the use of aluminum as the material for the capsule known from the prior art has the disadvantage that aluminum is expensive and high energy consumption arises in the production of aluminum.

Aus der WO 2008/087009 A2 ist eine Kunststoffkapsel bekannt, welche eine Substanz für die Herstellung eines Getränks mit einer Maschine enthält. Diese bekannte Kapsel ist bereits weniger kostspielig als beispielsweise Aluminium in der Herstellung und auch der Energieverbrauch für deren Herstellung ist gegenüber den bekannten Aluminiumkapseln verringert.From the WO 2008/087009 A2 a plastic capsule is known which contains a substance for the production of a drink with a machine. This known capsule is already less expensive to manufacture than aluminum, for example, and the energy consumption for its manufacture is also reduced compared to the known aluminum capsules.

Diese bekannte Kapsel weist jedoch den Nachteil auf, dass die Kunststoffkapsel in den Maschinen zur Lebensmittelherstellung oft nicht zuverlässig penetriert wird, wodurch unter Umständen Lebensmittel verringerter Qualität hergestellt werden, wenn nicht genügend Flüssigkeit entsprechend den jeweiligen Spezifikationen durch die Kapsel gefördert wird. Zudem ist es auch möglich, dass in der Vorrichtung ein grosser Überdruck entsteht, wenn die Kapsel nicht penetriert wird und die zugeführte Flüssigkeit somit nicht ohne weiteres abführbar ist, wodurch die Vorrichtung möglicherweise beschädigt werden kann. Zudem kann durch den Überdruck auch ein Sicherheitsrisiko für den Bediener entstehen.However, this known capsule has the disadvantage that the plastic capsule is often not reliably penetrated in the machines for food production, as a result of which food of reduced quality may be produced if not enough liquid is conveyed through the capsule in accordance with the respective specifications. In addition, it is also possible that a large overpressure arises in the device if the capsule is not penetrated and the supplied liquid cannot therefore be easily drained away, which may damage the device. In addition, the overpressure can also pose a safety risk for the operator.

Ein weiterer Nachteil des bekannten Stands der Technik ist die Notwendigkeit der Anordnung einer Einrichtung zur Penetrierung der Kapsel in der Vorrichtung, was kostspielig ist.Another disadvantage of the known prior art is the need to include means for penetrating the capsule in the device, which is expensive.

Es ist daher eine Aufgabe der vorliegenden Erfindung, die Nachteile des Bekannten zu vermeiden, insbesondere also eine Kapsel bereitzustellen, die bei bestimmungsgemässen Gebrauch in einer Vorrichtung zur Herstellung eines Lebensmittels eine erhöhte Betriebssicherheit ermöglicht, wenig Umwelt belastend und kostengünstig herstellbar ist. Zudem soll eine Kapsel bereitgestellt werden, die in einer Vorrichtung zur Getränkeherstellung ohne Penetrierungseinrichtung verwendbar ist.It is therefore an object of the present invention to avoid the disadvantages of the known, in particular to provide a capsule which, when used as intended in a device for producing a foodstuff, has an increased Operational safety enables, has little impact on the environment and is inexpensive to manufacture. In addition, a capsule is to be provided which can be used in a device for producing drinks without a penetration device.

Diese Aufgabe wird durch eine Kapsel mit den Merkmalen gemäss Anspruch 1 gelöst.This object is achieved by a capsule with the features according to claim 1.

Die erfindungsgemässe Kapsel besteht aus einem Kapselkörper mit einer Seitenwand und einem Boden. Der Kapselkörper ist vorzugsweise rotationssymmetrisch ausgebildet. Der Kapselkörper ist mit der Seitenwand und dem Boden einstückig ausgebildet. Die Kapsel umfasst einen den Kapselkörper abdeckenden Deckel zur Bildung einer geschlossenen Kammer, die eine Substanz für die Zubereitung eines Lebensmittels enthält. Der Kapselkörper weist zumindest einen Schlitz für die Durchleitung einer Flüssigkeit durch die Kapsel auf, der im Wesentlichen ohne Materialabtrag gebildet wird. Der Schlitz im Kapselkörper wird vor dem bestimmungsgemässen Gebrauch der Kapsel in einer Vorrichtung zur Herstellung eines Lebensmittels gebildet.The capsule according to the invention consists of a capsule body with a side wall and a bottom. The capsule body is preferably designed to be rotationally symmetrical. The capsule body is formed in one piece with the side wall and the bottom. The capsule comprises a lid covering the capsule body to form a closed chamber which contains a substance for the preparation of a foodstuff. The capsule body has at least one slot for the passage of a liquid through the capsule, which slot is formed essentially without material removal. The slot in the capsule body is formed in a device for producing a food product before the capsule is used as intended.

Unter der Formulierung "im Wesentlichen ohne Materialabtrag" wird im Sinne der vorliegenden Anmeldung ein nicht-spanendes Verfahren verstanden, mit dem der Schlitz gebildet wird, das heisst, dass im Wesentlichen kein Material bei der Bildung des Schlitzes von dem Kapselkörper entfernt wird. Dies kann beispielsweise mit einem Schneidverfahren erreicht werden, wenn ein geeignetes Schneidwerkzeug wie beispielsweise ein Messer verwendet wird.In the context of the present application, the phrase “essentially without material removal” is understood to mean a non-cutting process with which the slot is formed, that is to say that essentially no material is removed from the capsule body during the formation of the slot. This can be achieved, for example, with a cutting method if a suitable cutting tool such as a knife is used.

Unter der Formulierung, dass "der Schlitz im Kapselkörper vor dem bestimmungsgemässen Gebrauch der Kapsel in einer Vorrichtung zur Herstellung eines Lebensmittels gebildet wird", wird im Sinne der vorliegenden Anmeldung verstanden, dass der Schlitz im Kapselkörper während der Herstellung des Kapselkörpers, nach der Herstellung des Kapselkörpers oder nach der Abfüllung und Verschliessung der Kapsel mit einem Deckel gebildet wird und die Kapsel mit dem Schlitz im Kapselkörper verkauft und gelagert wird. Eine Kapsel, bei der ein Schlitz während der Verwendung in einer Vorrichtung zur Herstellung eines Lebensmittels durch eine Einrichtung der Vorrichtung gebildet wird, ist daher im Sinne der vorliegenden Anmeldung kein Schlitz im Kapselkörper, der vor dem bestimmungsgemässen Gebrauch der Kapsel gebildet wird.The formulation that "the slot in the capsule body is formed before the intended use of the capsule in a device for the production of a foodstuff" is used in the sense of the present application understood that the slot in the capsule body is formed during the production of the capsule body, after the production of the capsule body or after the filling and sealing of the capsule with a lid and the capsule with the slot in the capsule body is sold and stored. A capsule in which a slot is formed during use in a device for the production of a food by a device of the device is therefore not a slot in the capsule body for the purposes of the present application, which is formed before the intended use of the capsule.

Beispielsweise ist der Schlitz mit einem Messer und / oder einem Laser herstellbar.
Insbesondere ist die Kapsel geeignet zur Herstellung eines Lebensmittels und insbesondere eines Getränks in einer Vorrichtung ohne Penetrierungseinrichtung.
For example, the slot can be produced with a knife and / or a laser.
In particular, the capsule is suitable for producing a foodstuff and in particular a drink in a device without a penetration device.

Dies weist den Vorteil auf, dass die Herstellung einer kostengünstigeren Vorrichtung zur Herstellung eines Lebensmittels ermöglicht wird.This has the advantage that the production of a more cost-effective device for producing a food is made possible.

Unter einer "Penetrierungseinrichtung" wird im Sinne der vorliegenden Anmeldung eine Einrichtung verstanden, mit der die Kapsel bei bestimmungsgemässen Gebrauch in der Vorrichtung penetriert und insbesondere durchstochen werden kann, sodass Flüssigkeit durch die Kapsel durchgeleitet werden kann.In the context of the present application, a “penetration device” is understood to mean a device with which the capsule can be penetrated and in particular pierced in the device when used as intended, so that liquid can be passed through the capsule.

Unter dem Begriff "rotationssymmetrisch" wird im Sinne der vorliegenden Anmeldung eine Symmetrie bezüglich Rotation um die Längsachse der Kapsel um einen diskreten Winkel oder auch um beliebige Winkel verstanden.In the context of the present application, the term “rotationally symmetrical” is understood to mean symmetry with respect to rotation about the longitudinal axis of the capsule by a discrete angle or also by any angle.

Die Bildung von zumindest einem Schlitz im Kapselkörper hat den Vorteil, dass bei gegebenenfalls nicht zuverlässiger Penetrierung des Kapselkörpers die Flüssigkeit durch den Schlitz fliessen kann. Hierdurch wird vorteilhaft erreicht, dass ein Entstehen eines Überdrucks in der Vorrichtung vermieden werden kann, wodurch das Risiko einer Beschädigung der Vorrichtung verringert wird. Zudem kann durch die Anordnung des Schlitzes im Kapselkörper eine konstantere Qualität des hergestellten Lebensmittels erreicht wird, da zumindest ein gewisser Durchfluss durch die Vorrichtung gewährleistet wird. Ein weiterer Vorteil ist die Verwendbarkeit der erfindungsgemässen Kapsel in einer Vorrichtung zur Herstellung eines Lebensmittels ohne Penetrierungseinrichtung.The formation of at least one slot in the capsule body has the advantage that if the penetration of the capsule body is possibly not reliable, the liquid can flow through the slot. This advantageously means that the creation of an overpressure in the device can be avoided, as a result of which the risk of damage to the device is reduced. In addition, the arrangement of the slot in the capsule body makes it possible to achieve a more constant quality of the food produced, since at least a certain flow through the device is ensured. Another advantage is that the capsule according to the invention can be used in a device for producing a foodstuff without a penetration device.

Insbesondere ist als Substanz Kaffee, Tee und Schokolade oder beliebige Kombinationen daraus verwendbar.In particular, coffee, tea and chocolate or any combination thereof can be used as the substance.

Insbesondere kann also beispielsweise durch Parameter wie beispielsweise der Länge des Schlitzes, der Wandstärke des Kapselkörpers und des Materials des Kapselkörpers oder beliebigen Kombination aus diesen Parametern das Öffnungsverhalten des Schlitzes vorteilhaft beim bestimmungsgemässen Gebrauch beeinflusst werden; beispielsweise ist es dadurch möglich, dass der Schlitz sich zur Durchleitung einer Flüssigkeit erst dann öffnet, wenn ein bestimmter Überdruck in der Vorrichtung erreicht wird, der lediglich bei nicht korrektem Penetrieren der Kapsel in der Vorrichtung besteht; der Schlitz kann somit als Sicherheitsventil und / oder als Durchflussregelungseinrichtung fungieren.In particular, parameters such as the length of the slot, the wall thickness of the capsule body and the material of the capsule body or any combination of these parameters can advantageously influence the opening behavior of the slot when used as intended; For example, it is possible that the slot for the passage of a liquid only opens when a certain overpressure is reached in the device, which only exists if the capsule is not properly penetrated in the device; the slot can thus function as a safety valve and / or as a flow control device.

Bevorzugt berühren sich die gegenüberliegenden Kanten des Schlitzes in einer Ruheposition zumindest abschnittsweise. Bevorzugt berühren sich die gegenüberliegenden Kanten des Schlitzes auf zumindest 90 % einer Länge l des Schlitzes, besonders bevorzugt auf zumindest 95 % und ganz besonders bevorzugt auf 100 %. Unter dem Begriff "100 %" wird eine Berührung auf im Wesentlichen der gesamten Länge l des Schlitzes verstanden.The opposite edges of the slot preferably touch at least in sections in a rest position. The opposite edges of the slot preferably touch one another over at least 90% of a length l of the slot, in particular preferably to at least 95% and very particularly preferably to 100%. The term “100%” is understood to mean contact over essentially the entire length l of the slot.

Unter einer "Ruheposition" wird im Sinne der vorliegenden Anmeldung die Position des Schlitzes verstanden, in der beispielsweise durch die Vorrichtung zur Herstellung eines Lebensmittels keine Kraft auf den Kapselkörper ausgeübt wird. Bei einer derartigen Kraft kann es sich beispielsweise um eine mechanische Krafteinwirkung zur Deformierung des Kapselkörpers handeln, wodurch sich der Schlitz aus der Ruheposition bewegen würde. Alternativ oder zusätzlich kann es sich beispielsweise auch um eine hydraulische Krafteinwirkung handeln, die bei der Zuführung einer Flüssigkeit unter Druck in die Kapsel zum Extrahieren der Substanz in der Kapsel entsteht, beispielsweise zum Aufbrühen eines Kaffeegetränks.In the context of the present application, a “rest position” is understood to mean the position of the slot in which, for example, no force is exerted on the capsule body by the device for producing a foodstuff. Such a force can be, for example, a mechanical force to deform the capsule body, as a result of which the slot would move from the rest position. As an alternative or in addition, it can also be, for example, a hydraulic force that arises when a liquid is fed into the capsule under pressure to extract the substance in the capsule, for example for brewing a coffee drink.

Die Ausgestaltung des Schlitzes derart, dass sich die gegenüberliegenden Kanten zumindest abschnittweise berühren in der Ruheposition hat den Vorteil, dass die Kapsel im Wesentlichen geschlossen ist und keine Substanz aus dem Kapselkörper gelangen kann.The configuration of the slot in such a way that the opposite edges touch at least in sections in the rest position has the advantage that the capsule is essentially closed and no substance can get out of the capsule body.

Besonders bevorzugt ist der Schlitz mittels einer Krafteinwirkung öffenbar von einer Ruheposition in eine Offenposition. Insbesondere ist der Schlitz öffenbar mittels einer mechanischen und/oder hydraulischen Krafteinwirkung.Particularly preferably, the slot can be opened from a rest position into an open position by means of an action of force. In particular, the slot can be opened by means of a mechanical and / or hydraulic force.

Unter einer "Offenposition" des Schlitzes wird im Sinne der vorliegenden Anmeldung diejenige Position des Schlitzes verstanden, bei der die gegenüberliegenden Kanten des Schlitzes durch die Krafteinwirkung voneinander beabstandet sind zur Durchleitung der Flüssigkeit.In the context of the present application, an “open position” of the slot is understood to mean that position of the slot in which the opposite edges of the slot are spaced apart by the action of force for the passage of the liquid.

Dies hat den Vorteil, dass der Schlitz in Abhängigkeit von der Krafteinwirkung von der Ruheposition in die Offenposition öffenbar ist, beispielsweise zur Anpassung des Durchflusses durch den Schlitz in Abhängigkeit von der Krafteinwirkung.This has the advantage that the slot can be opened from the rest position into the open position as a function of the action of force, for example to adapt the flow through the slot as a function of the action of force.

Ganz besonders bevorzugt ist der Schlitz mittels Erzeugung einer Druckdifferenz zumindest im Bereich des Schlitzes zwischen der Kammer und der Aussenseite des Kapselkörpers öffenbar, insbesondere bei Erzeugung der Druckdifferenz mittels einer unter Druck zuführbaren Flüssigkeit. Mit anderen Worten ist der Schlitz öffenbar mittels einer Druckdifferenz zwischen der Aussenseite der Kapsel und der durch die Kammer gebildeten Innenseite der Kapsel.Most preferably, the slot can be opened by generating a pressure difference at least in the area of the slot between the chamber and the outside of the capsule body, in particular when the pressure difference is generated by means of a liquid that can be supplied under pressure. In other words, the slot can be opened by means of a pressure difference between the outside of the capsule and the inside of the capsule formed by the chamber.

Dies hat den Vorteil, dass der Schlitz in Abhängigkeit von der sich in der Vorrichtung einstellenden Druckdifferenz zwischen der Innenseite und der Aussenseite der Kapsel beispielsweise durch die Zuführung einer Flüssigkeit zur Extraktion der Substanz öffnen kann zur weiter verbesserten und sichereren Verwendung der Kapsel in der Vorrichtung.This has the advantage that the slot can open depending on the pressure difference between the inside and the outside of the capsule, for example by adding a liquid to extract the substance, for further improved and safer use of the capsule in the device.

Bevorzugt ist der Schlitz nach Wegnahme der Krafteinwirkung im Wesentlichen reversibel schliessbar und kehrt im Wesentlichen in die Ruheposition zurück.Preferably, after the force has been removed, the slot can essentially be closed reversibly and essentially returns to the rest position.

Dies hat den Vorteil, dass nach der Herstellung des Lebensmittels der Schlitz im Wesentlichen sich wieder automatisch verschliesst und daher die extrahierte Substanz in der Kapsel eingeschlossen bleibt, was zu einer verbesserten Handhabung führt. Zudem hat dies den Vorteil, dass der Schlitz sich gegebenenfalls lediglich bei einem gewissen Überdruck öffnet und nach Abbau des Überdrucks wieder schliesst, sodass die Herstellung des Lebensmittels unter gegebenenfalls standardisierten Betriebsbedingungen erfolgen kann zur Erzielung einer möglichst konstanten und hohen Qualität des Lebensmittels.This has the advantage that after the production of the food the slot closes again essentially automatically and therefore the extracted substance remains enclosed in the capsule, which leads to improved handling. In addition, this has the advantage that the slot opens, if necessary, only at a certain excess pressure and closes again after the excess pressure has been relieved, so that the food can be produced under possibly standardized operating conditions can be done to achieve the highest possible quality of the food that is as constant as possible.

Besonders bevorzugt verbleibt der Schlitz nach dem Öffnen mittels der Krafteinwirkung in die Offenposition und der Zuführung von thermischer Energie im Wesentlichen in der Offenposition. Mit anderen Worten verbleibt der Schlitz nach Wegnahme der Druckdifferenz in der Offenposition. Insbesondere verbleibt der Schlitz nach dem Öffnen mittels einer Flüssigkeit zur Erzeugung der Druckdifferenz in der Offenposition, wenn die Flüssigkeit eine Temperatur grösser 70° C, bevorzugt grösser 75° C und besonders bevorzugt grösser 80° C aufweist zur Zuführung der thermischen Energie.
Insbesondere wird der Kapselkörper zumindest im Bereich des Schlitzes durch die thermische Energie im Wesentlichen irreversibel verformt, sodass der Schlitz in der Offenposition verbleibt.
Particularly preferably, the slot remains essentially in the open position after opening by means of the action of force in the open position and the supply of thermal energy. In other words, the slot remains in the open position after the pressure difference has been removed. In particular, after opening by means of a liquid to generate the pressure difference, the slot remains in the open position if the liquid has a temperature greater than 70 ° C., preferably greater than 75 ° C. and particularly preferably greater than 80 ° C. for supplying the thermal energy.
In particular, the capsule body is essentially irreversibly deformed by the thermal energy, at least in the region of the slot, so that the slot remains in the open position.

Dies hat den Vorteil, dass auch beispielsweise bei Reduzierung der Pumpleistung für die zugeführte Flüssigkeit ein guter Durchfluss durch die Kapsel gewährleistet wird, da der Schlitz in der Offenposition verbleibt auch bei einer Reduzierung der Druckdifferenz.This has the advantage that a good flow through the capsule is ensured even when the pump power for the supplied liquid is reduced, for example, since the slot remains in the open position even when the pressure difference is reduced.

Ganz besonders bevorzugt ist die Offenposition des Schlitzes abhängig von der Druckdifferenz, derart, dass bei Erhöhung der Druckdifferenz die Öffnung des Schlitzes in der Offenposition vergrösserbar ist.The open position of the slot is very particularly preferably dependent on the pressure difference, such that when the pressure difference increases, the opening of the slot in the open position can be enlarged.

Dies hat den Vorteil, dass die Öffnung des Schlitzes in der Offenposition mit der Druckdifferenz, beispielsweise erzeugt durch eine variierende Pumpleistung, an die jeweilige Druckdifferenz anpassbar ist und somit eine Durchflussregelung erreicht wird. Der Kapselkörper ist mittels Tiefziehen hergestellt und besteht aus einem Polymer. Der Kapselkörper hat eine Wandstärke im Bereich von 0,05 nun bis 0,4 mm, bevorzugt im Bereich von 0,06 mm bis 0,3 mm und besonders bevorzugt im Bereich von 0,07 mm bis 0,25 mm.This has the advantage that the opening of the slot in the open position with the pressure difference, for example generated by a varying pump power, can be adapted to the respective pressure difference and thus a flow control is achieved. The capsule body is made by deep drawing and consists of a polymer. The capsule body has a wall thickness in the range from 0.05 mm to 0.4 mm, preferably in the range from 0.06 mm to 0.3 mm and particularly preferably in the range from 0.07 mm to 0.25 mm.

Unter der "Wandstärke" des Kapselkörpers wird im Sinne der vorliegenden Anmeldung die mittlere Wandstärke des Bodens und der Seitenwand verstanden.In the context of the present application, the “wall thickness” of the capsule body is understood to mean the mean wall thickness of the base and the side wall.

Die Herstellung des Kapselkörpers mittels Tiefziehen hat den Vorteil, dass dies kostengünstig möglich ist. Insbesondere hat zudem die geringe Wandstärke den Vorteil, dass dadurch der Materialverbrauch bei der Herstellung der Kapsel verringert wird und somit die Kosten weiter gesenkt werden können.The production of the capsule body by means of deep drawing has the advantage that this can be done inexpensively. In particular, the small wall thickness also has the advantage that it reduces the material consumption in the manufacture of the capsule and thus the costs can be further reduced.

Besonders bevorzugt weist der Schlitz eine Länge 1 im Bereich von 0,1 bis 20 mm, bevorzugt von 1 mm bis 15 mm und besonders bevorzugt von 3 mm bis 8 mm auf.The slot particularly preferably has a length 1 in the range from 0.1 to 20 mm, preferably from 1 mm to 15 mm and particularly preferably from 3 mm to 8 mm.

Dies hat den Vorteil, dass die Ausgestaltung des Schlitzes an die jeweiligen Anforderungen des herzustellenden Lebensmittels und/oder der verwendeten Vorrichtung zur Herstellung des Lebensmittels anpassbar ist.This has the advantage that the design of the slot can be adapted to the respective requirements of the foodstuff to be produced and / or the device used for producing the foodstuff.

Ganz besonders bevorzugt weist der Schlitz in der Offenstellung eine maximale Breite b von 6 mm, insbesondere von 5 mm und weiter insbesondere von 4 mm. In der Geschlossenstellung weist der Schlitz insbesondere eine Breite b von etwa 0 mm auf.In the open position, the slot very particularly preferably has a maximum width b of 6 mm, in particular 5 mm and further in particular 4 mm. In the closed position, the slot has, in particular, a width b of approximately 0 mm.

Dies hat den Vorteil der weiteren Verbesserung der Durchflussregelung in Abhängigkeit von den jeweiligen Anforderungen bei der Herstellung des Lebensmittels.This has the advantage of further improving the flow control depending on the respective requirements in the production of the food.

Bevorzugt ist der Schlitz im Boden angeordnet.The slot is preferably arranged in the floor.

Dies hat den Vorteil, dass die zugeführte Flüssigkeit, welche durch die Schlitze gefördert wird, einen möglichst grossen Anteil der zu extrahierenden Substanz benetzen kann, da die Flüssigkeit im Wesentlichen die gesamte Länge der Kapsel durchströmen muss, sodass ein qualitativ hochwertiges Produkt herstellbar ist mit einer möglichst geringen Menge an Substanz, was die Herstellung der Kapsel kostengünstiger macht.This has the advantage that the supplied liquid, which is conveyed through the slots, can wet the largest possible proportion of the substance to be extracted, since the liquid has to flow through essentially the entire length of the capsule, so that a high-quality product can be produced with a the smallest possible amount of substance, which makes the production of the capsule cheaper.

Besonders bevorzugt weist der Boden zumindest zwei Schlitze auf, die sich insbesondere kreuzen, bevorzugt etwa im geometrischen Mittelpunkt des Bodens.The base particularly preferably has at least two slots which in particular intersect, preferably approximately in the geometric center of the base.

Dies hat den Vorteil, dass die Fläche der durch die zumindest zwei Schlitze gebildeten Öffnungen vergrössert wird, sodass mehr Flüssigkeit durch diese gefördert werden kann zur besseren Extraktion der Substanz. Die Anordnung von zumindest zwei Schlitzen im Boden, die sich insbesondere kreuzen, bevorzugt etwa im geometrischen Mittelpunkt, hat den weiteren Vorteil, dass sich in Abhängigkeit von der erzeugten Druckdifferenz sich grössere Öffnungen der Schlitze bilden können zur besseren Durchflussregelung.This has the advantage that the area of the openings formed by the at least two slits is enlarged so that more liquid can be conveyed through them for better extraction of the substance. The arrangement of at least two slots in the base, which intersect in particular, preferably approximately in the geometric center, has the further advantage that, depending on the pressure difference generated, larger openings of the slots can be formed for better flow control.

Ganz besonders bevorzugt ist der Schlitz in der Seitenwand angeordnet. Insbesondere ist der Schlitz bezogen auf die auf die Gesamtlänge der Kapsel entlang der Längsachse der Kapsel entlang der mittleren Strömung der Flüssigkeit durch die Kapsel in einer ersten Hälfte, bevorzugt in einem ersten Dritten und besonders bevorzugt in einem ersten Viertel der Seitenwand angeordnet. Mit anderen Worten ist der Schlitz in Strömungsrichtung vom Boden aus betrachtet beispielsweise in der ersten Hälfte, im ersten Drittel oder im ersten Viertel der Seitenwand bezogen auf die Länge entlang der Längsachse der Kapsel.The slot is very particularly preferably arranged in the side wall. In particular, the slot is arranged in a first half, preferably in a first third and particularly preferably in a first quarter of the side wall based on the total length of the capsule along the longitudinal axis of the capsule along the mean flow of the liquid through the capsule. In other words, the slot is, for example, in the first half, in the first half, when viewed from the bottom in the direction of flow Third or in the first quarter of the side wall based on the length along the longitudinal axis of the capsule.

Dies hat den Vorteil, dass durch diese Anordnung des Schlitzes die Zuführung von Flüssigkeit in die Kapsel weiter verbessert wird sowie auch die Durchflussregelung. Insbesondere hat die Anordnung der Schlitze in einer ersten Hälfte bezogen auf die Länge der Kapsel und die Strömungsrichtung der Flüssigkeit den Vorteil, dass ein möglichst grosser Anteil der Substanz von der durch den in der Seitenwand angeordneten Schlitz benetzbar ist, was die Qualität des hergestellten Lebensmittels verbessert und zu einem geringeren Bedarf an Substanz führt, was kostengünstig ist.This has the advantage that this arrangement of the slot further improves the supply of liquid into the capsule, as well as the flow control. In particular, the arrangement of the slots in a first half, based on the length of the capsule and the direction of flow of the liquid, has the advantage that the largest possible proportion of the substance can be wetted by the slot arranged in the side wall, which improves the quality of the food produced and leads to a lower need for substance, which is inexpensive.

Bevorzugt ist der Schlitz im Wesentlichen entlang des Umfangs der Seitenwand angeordnet. Mit anderen Worten ist also der Schlitz im Wesentlichen parallel zu einem Umfang des insbesondere rotationssymmetrisch ausgebildeten Kapselkörpers angeordnet.The slot is preferably arranged essentially along the circumference of the side wall. In other words, the slot is arranged essentially parallel to a circumference of the capsule body, in particular, which is designed to be rotationally symmetrical.

Der Umfang der Seitenwand ist also beispielsweise bei einem konusförmig ausgebildeten Kapselkörper im Wesentlichen ein Kreis in einer Ebene senkrecht zur Längsachse der Kapsel.The circumference of the side wall is therefore essentially a circle in a plane perpendicular to the longitudinal axis of the capsule in the case of a conical capsule body, for example.

Diese Anordnung des Schlitzes im Wesentlichen entlang des Umfangs oder in einem Winkel mit dem Umfang hat den Vorteil der weiter verbesserten Durchflussregelung und führt zu einer erhöhten Extraktionseffizienz der Substanz.This arrangement of the slot essentially along the circumference or at an angle with the circumference has the advantage of further improved flow control and leads to an increased extraction efficiency of the substance.

Insbesondere ist es möglich, bei Anordnung von mehreren Schlitzen diese in Kombination gemäss den oben offenbarten Anordnungen anzuordnen. Beispielsweise ist es möglich, im Boden zwei sich im geometrischen Mittelpunkt angeordnete Schlitze vorzusehen sowie zumindest einen Schlitz im Wesentlichen entlang des Umfangs und einen weiteren Schlitz im Wesentlichen senkrecht zum Umfang.In particular, when a plurality of slots are arranged, these can be arranged in combination in accordance with the arrangements disclosed above. For example, it is possible to provide two slots arranged in the geometric center point in the floor as well at least one slot essentially along the circumference and a further slot essentially perpendicular to the circumference.

Ganz besonders bevorzugt ist im Bereich der Kanten des Schlitzes auf der der Kammer zugewandten Seite kein Wulst angeordnet.Very particularly preferably, no bead is arranged in the region of the edges of the slot on the side facing the chamber.

Ein derartiger Wulst kann beispielsweise bei der Erzeugung des Schlitzes beispielsweise durch das Schneidwerkzeug entstehen. Die Vermeidung der Anordnung eines derartigen Wulstes hat den Vorteil, dass die Strömung der Flüssigkeit in der Kapsel im Bereich des Schlitzes nicht negativ beeinflusst wird und damit die Durchflussregelung und / oder der Durchfluss verbessert wird.Such a bead can arise, for example, when the slot is produced, for example by the cutting tool. Avoiding the arrangement of such a bead has the advantage that the flow of the liquid in the capsule in the area of the slot is not negatively influenced and thus the flow regulation and / or the flow is improved.

Bevorzugt weist der Kapselkörper zumindest zwei Schlitze, insbesondere zumindest drei Schlitze und weiter insbesondere vier Schlitze auf.The capsule body preferably has at least two slots, in particular at least three slots and further in particular four slots.

Dies hat den Vorteil der weiter verbesserten Durchflussregelung und der verbesserten Extraktion der Substanz zur Erhöhung der Qualität des hergestellten Lebensmittels.This has the advantage of the further improved flow control and the improved extraction of the substance to increase the quality of the food produced.

Besonders bevorzugt ist der Schlitz im Wesentlichen als gerader Schlitz ausgebildet.The slot is particularly preferably designed essentially as a straight slot.

Ganz besonders bevorzugt ist der Schlitz im Wesentlichen als gekrümmter Schlitz ausgebildet.The slot is very particularly preferably designed essentially as a curved slot.

Dies hat den Vorteil, dass der Schlitz in Abhängigkeit der Anforderungen in seiner Form entsprechend gewählt werden kann. Bei der Anordnung von zumindest zwei Schlitzen ist auch eine Kombination von geraden und gekrümmten Schlitzen möglich.This has the advantage that the shape of the slot can be selected as a function of the requirements. With the arrangement of at least two slots, a combination of straight and curved slots is also possible.

Bevorzugt ist der Schlitz derart ausgebildet, dass vor einem Extrahieren der Substanz zur Lebensmittelherstellung im Wesentlichen keine Substanz durch den Schlitz hindurch treten kann.The slot is preferably designed in such a way that essentially no substance can pass through the slot before the substance is extracted for food production.

Insbesondere weist eine Substanz eine Partikelgrössenverteilung im Bereich von grösser 0 µm bis 800 µm, bevorzugt von 25 µm bis 750 µm und besonders bevorzugt von 50 µm bis 700 µm auf. Eine Substanz weist eine derartige Partikelgrössenverteilung auf, wenn zumindest 95 Gew.-%, bevorzugt 97 Gew.-% und besonders bevorzugt 99 Gew.-% der Partikel eine Partikelgrösse in den vorstehend definierten Bereichen aufweisen. Unter einer Partikelgrösse wird im Sinne der vorliegenden Anmeldung die grösste Ausdehnung eines Partikels verstanden.In particular, a substance has a particle size distribution in the range from greater than 0 μm to 800 μm, preferably from 25 μm to 750 μm and particularly preferably from 50 μm to 700 μm. A substance has such a particle size distribution if at least 95% by weight, preferably 97% by weight and particularly preferably 99% by weight of the particles have a particle size in the ranges defined above. In the context of the present application, a particle size is understood to mean the largest dimension of a particle.

Dies hat den Vorteil, dass die Handhabung der Kapsel verbessert wird und während der Lagerung oder auch des Transports Substanz nicht aus der Kapsel entweichen kann, was unter Umständen zu einer verringerten Qualität führen kann, da die Kapsel in einem derartigen Fall weniger Substanz als vorgegeben enthalten kann.This has the advantage that the handling of the capsule is improved and substance cannot escape from the capsule during storage or transport, which may lead to a reduced quality, since in such a case the capsule contain less substance than specified can.

Erfindungsgemäss ist der Schlitz mit einer im Wesentlichen luftundurchlässigen Schicht verschlossen. Die luftundurchlässige Schicht ist auf der der Kammer abgewandten und / oder zugewandten Seite des Kapselkörpers angeordnet.According to the invention, the slot is closed with an essentially air-impermeable layer. The air-impermeable layer is arranged on the side of the capsule body facing away from and / or facing the chamber.

Dies hat den Vorteil, dass die Kapsel mittels der luftundurchlässigen Schicht im Wesentlichen aromadicht verschliessbar ist und damit für die Lagerung oder den Transport keine zusätzliche äussere Hülle notwendig ist, was die Herstellung der Kapsel kostspieliger machen kann und die Handhabung durch den Bediener erschwert.This has the advantage that the capsule can be closed in an essentially aroma-tight manner by means of the air-impermeable layer and therefore no additional outer shell is necessary for storage or transport, which can make the production of the capsule more expensive and make handling by the operator more difficult.

Bevorzugt ist die Schicht im Wesentlichen vollflächig an dem Kapselkörper und insbesondere an der Seitenwand und/oder dem Boden aufgebracht.The layer is preferably applied essentially over the entire surface of the capsule body and in particular on the side wall and / or the base.

Dies hat den Vorteil eines vereinfachten Beschichtungsverfahrens, da unabhängig von der Position der Schlitze der gesamte Kapselkörper beschichtet wird, was das Verfahren einfacher durchführbar und somit kostengünstiger macht.This has the advantage of a simplified coating process, since the entire capsule body is coated regardless of the position of the slots, which makes the process easier to carry out and thus more cost-effective.

Bevorzugt wird die Schicht abschnittsweise zur Verschliessung des Schlitzes aufgebracht.The layer is preferably applied in sections to close the slot.

Dies hat den Vorteil des verringerten Verbrauchs an Material für die Schicht, was die Materialkosten reduziert. Weiterhin hat dies den Vorteil, dass weniger Material der Schicht in das Lebensmittel gelangt, da die Schicht während der Herstellung des Lebensmittels mit der Flüssigkeit in Kontakt steht, die zur Herstellung des Lebensmittels verwendet wird.This has the advantage of the reduced consumption of material for the layer, which reduces the material costs. Furthermore, this has the advantage that less material of the layer gets into the food, since the layer is in contact with the liquid that is used to produce the food during the production of the food.

Besonders bevorzugt ist die Schicht auf zumindest einer der gegenüberliegenden Kanten und insbesondere auf beiden gegenüberliegenden Kanten des Schlitzes aufgebracht.The layer is particularly preferably applied to at least one of the opposite edges and in particular to both opposite edges of the slot.

Dies hat den Vorteil der weiteren Reduzierung des benötigten Materials für die Schicht mit dem vorstehend erläuterten Vorteil. Weiterhin ist in Abhängigkeit von dem gewählten Material für die Schicht eine gezielte Verklebung des Schlitzes möglich, was zu einer weiter verbesserten Abdichtung und gegebenenfalls besser definierten Öffnungseigenschaften des Schlitzes unter Druck führt.This has the advantage of further reducing the material required for the layer with the advantage explained above. Furthermore, depending on the material selected for the layer, targeted gluing of the slot is possible, which leads to a further improved sealing and possibly better defined opening properties of the slot under pressure.

Ganz besonders bevorzugt besteht die Schicht zumindest aus einem lösbaren und lebensmitteltauglichen Material, aus Aluminium oder einem lösbarem Polymer oder beliebigen Kombination daraus. Das Polymer schmilzt insbesondere bei Temperaturen > 50° C. Insbesondere kann Zucker, Polysacharid, Hydrogel, Biopolymer, Wachs und Parafin oder beliebige Kombinationen daraus zur Bildung der im Wesentlichen luftundurchlässige Schicht verwendet werden.The layer very particularly preferably consists at least of a detachable and food-grade material, of aluminum or a detachable polymer or any combination thereof. That Polymer melts in particular at temperatures> 50 ° C. In particular, sugar, polysaccharide, hydrogel, biopolymer, wax and paraffin or any combination thereof can be used to form the essentially air-impermeable layer.

Dies hat den Vorteil, dass bei Verwendung eines lösbaren und lebensmitteltauglichen Materials und / oder eines lösbaren Polymers die Schicht während der Herstellung des Lebensmittels sich auflöst und damit gegebenenfalls die Herstellung ermöglicht. Die Verwendung eines lebensmitteltauglichen Materials wie beispielsweise einer löslichen Zuckerschicht hat den Vorteil, dass dieser für die Herstellung des Lebensmittels unbedenklich ist.This has the advantage that when a releasable and food-grade material and / or a releasable polymer is used, the layer dissolves during the production of the food and thus possibly enables production. The use of a food-grade material such as a soluble sugar layer has the advantage that it is harmless for the production of the food.

Die Verwendung von Aluminium hat den Vorteil, dass eine zuverlässigere Abdichtung erzielbar ist. Die Aluminiumschicht wird vor dem Gebrauch entweder vom Kapselkörper entfernt oder so an und/oder in der Kapsel befestigt, dass diese gegebenenfalls mittels der zugeführten Flüssigkeit vom Schlitz gelöst wird und jedoch weiter an der Kapsel befestigt bleibt. Alternativ ist es auch möglich, dass die Aluminiumschicht unter Druck zerreisst und / oder von gegebenenfalls entsprechend angeordneten Penetrierungsmitteln durchstossen wird. Dies hat den Vorteil, dass das hergestellte Lebensmittel nicht durch das Aluminium verunreinigt ist.The use of aluminum has the advantage that a more reliable seal can be achieved. Before use, the aluminum layer is either removed from the capsule body or attached to and / or in the capsule in such a way that it is detached from the slot by means of the supplied liquid, but remains attached to the capsule. Alternatively, it is also possible that the aluminum layer tears under pressure and / or is pierced by penetrating means, which may be appropriately arranged. This has the advantage that the food produced is not contaminated by the aluminum.

Zwischen der Substanz und dem Schlitz kann eine im Wesentlichen luftundurchlässige und aromadichte Membran angeordnet sein zur Abdichtung der geschlossenen Kammer gegenüber dem Schlitz. Die Membran ist insbesondere im Kapselkörper befestigt. Mit anderen Worten enthält die geschlossene Kammer die Substanz, wobei in dem Kapselkörper die im Wesentlichen luftundurchlässige Membran angeordnet ist, so dass keine direkte Fluidverbindung für beispielsweise Flüssigkeiten und/oder Gase vom Schlitz zur Substanz vor Gebrauch der Kapsel besteht.A substantially air-impermeable and aroma-tight membrane can be arranged between the substance and the slot in order to seal the closed chamber from the slot. The membrane is fastened in particular in the capsule body. In other words, the closed chamber contains the substance, the essentially air-impermeable membrane being arranged in the capsule body, so that no direct fluid connection for example Liquids and / or gases from the slot to the substance before the capsule is used.

Dies hat den Vorteil, dass das Material des Kapselkörpers und das Material der Membran unterschiedlich auswählbar sind im Hinblick auf die Durchstechbarkeit mit einer Penetriereinrichtung der Vorrichtung zur Zubereitung des Lebensmittels. Dies erhöht die Zuverlässigkeit der Durchstechung der Kapsel im Betrieb, so dass das Lebensmittel zuverlässig zubereitet werden kann. Zudem erlaubt dies eine kostengünstige Herstellung des Kapselkörpers, der beispielsweise aus Kunststoff herstellbar ist.This has the advantage that the material of the capsule body and the material of the membrane can be selected differently with regard to the pierceability with a penetration device of the device for preparing the food. This increases the reliability of the piercing of the capsule in operation, so that the food can be reliably prepared. In addition, this allows a cost-effective production of the capsule body, which can be produced from plastic, for example.

Im Betrieb ist häufig bei Verwendung von Kunststoffkapseln, die beispielsweise aus einem Polymer bestehen, zu beobachten, dass nach der Durchstechung des Kapselkörpers mit einer Penetrierungseinrichtung durch ein teilweise elastisches Verhalten des Kapselkörpers die durch die Penetriereinrichtung erzeugte Penetrieröffnung wieder teilweise verschlossen werden, so dass nicht genügend Flüssigkeit zur Zubereitung des Lebensmittels zugeführt werden kann. Durch die Anordnung von zumindest einem Schlitz im Kapselkörper kann nun sichergestellt werden, dass auch nach einer teilweisen Verschliessung der Penetrieröffnungen durch das elastische Verhalten des Materials des Kapselkörpers ausreichend Flüssigkeit in die geschlossene Kammer der Kapsel zuführbar ist. Durch die Anordnung des zumindest einen Schlitzes im Kapselkörper wird jedoch verhindert, dass die Kapsel im Wesentlichen Luftdicht verschlossen ist zur Bildung einer aromadichten Verpackung; in diesem Fall ist es beispielsweise bei Verwendung von Kaffee als extrahierbare Substanz empfehlenswert, die Kapsel für den Transport und/oder die Lagerung der Kapsel in eine äussere Hülle im wesentlichen luftdicht zu verschliessen, was jedoch den Nachteil hat, dass mehr Verpackungsmaterial verbraucht wird und zudem jede verpackte Kapsel ein grösseres Volumen als die Kapsel als solche einnimmt. Durch Anordnung der im Wesentlichen luftundurchlässigen Membran in der Kapsel zwischen Schlitz und Substanz kann die Substanz im Wesentlichen luftdicht in der Kapsel verschlossen werden, so dass eine aromadichte Kapsel gebildet wird.In operation, when using plastic capsules, which for example consist of a polymer, it can often be observed that after the capsule body has been pierced with a penetration device, the penetration opening generated by the penetration device is partially closed again due to a partially elastic behavior of the capsule body, so that not enough Liquid can be supplied to prepare the food. By arranging at least one slot in the capsule body, it can now be ensured that sufficient liquid can be fed into the closed chamber of the capsule even after partial closure of the penetration openings due to the elastic behavior of the material of the capsule body. The arrangement of the at least one slot in the capsule body, however, prevents the capsule from being closed in an essentially airtight manner in order to form an aroma-tight packaging; In this case, for example, when using coffee as the extractable substance, it is advisable to close the capsule essentially airtight for transport and / or storage of the capsule in an outer shell, but this has the disadvantage that more packaging material is used and moreover each packed capsule has a larger volume than the capsule as such. By arranging the essentially air-impermeable membrane in the capsule between the slit and the substance, the substance can be sealed essentially airtight in the capsule, so that an aroma-tight capsule is formed.

Bei Anordnung von mehr als einem Schlitz im Kapselkörper können die Formen der Schlitze entsprechend den Anforderungen beliebig kombiniert werden.If more than one slot is arranged in the capsule body, the shapes of the slots can be combined as required according to requirements.

Bevorzugt ist die im Wesentlichen luftundurchlässige Membran zumindest im Bereich des zumindest einen Schlitzes beabstandet von der Seitenwand und/oder dem Boden angeordnet. Insbesondere ist die im Wesentlichen luftundurchlässige Membran beabstandet vom gesamten Boden angeordnet.The substantially air-impermeable membrane is preferably arranged at least in the region of the at least one slot at a distance from the side wall and / or the bottom. In particular, the substantially air-impermeable membrane is arranged at a distance from the entire floor.

Dies hat den Vorteil, dass nach der Durchstechung der Membran durch die Penetrierungseinrichtung eine Strömungsverbindung vom Schlitz zu der Position der Durchstechung der Membran gebildet wird für eine zuverlässige Extraktion der Substanz zur Zubereitung des Lebensmittels. Insbesondere bei Beabstandung der Membran vom gesamten Boden und bei Anordnung mehrerer Schlitze im Boden kann so eine zuverlässige und schnelle Extraktion der Substanz zur Zubereitung des Lebensmittels folgen.This has the advantage that after the membrane has been pierced by the penetration device, a flow connection is formed from the slot to the position of the piercing of the membrane for reliable extraction of the substance for preparing the food. In particular, when the membrane is at a distance from the entire base and when several slots are arranged in the base, a reliable and rapid extraction of the substance for the preparation of the food can follow.

Unter der Beabstandung der Membran vom Schlitz wird vorliegend verstanden, dass die Membran nicht am Kapselkörper in dem Bereich anliegt, in dem der Schlitz angeordnet ist.In the present case, the spacing of the membrane from the slot is understood to mean that the membrane does not bear against the capsule body in the area in which the slot is arranged.

Bevorzugt weist der Kapselkörper zumindest zwei Schlitze auf, wobei alle Schlitze auf der der Substanz abgewandten Seite der im Wesentlichen luftundurchlässigen Membran angeordnet sind.The capsule body preferably has at least two slits, all slits being arranged on the side of the essentially air-impermeable membrane facing away from the substance.

Dies hat den Vorteil, dass keine direkte Fluidverbindung zwischen der Umgebung und der Substanz durch Anordnung der Schlitze im Kapselkörper entsteht zur vereinfachten Abdichtung der geschlossenen Kammer, in der die Substanz angeordnet ist.This has the advantage that there is no direct fluid connection between the environment and the substance due to the arrangement of the slots in the capsule body in order to simplify sealing of the closed chamber in which the substance is arranged.

Bevorzugt ist die im Wesentlichen luftundurchlässige Membran derart angeordnet, dass die Membran bei bestimmungsgemässem Gebrauch von einer Penetrierungseinrichtung der Vorrichtung zur Zubereitung des Lebensmittels im Betrieb penetrierbar ist.The substantially air-impermeable membrane is preferably arranged in such a way that, when used as intended, the membrane can be penetrated by a penetration device of the device for preparing the foodstuff during operation.

Dies hat den Vorteil, dass der Kapselkörper und die Membran mit der gleichen Penetrierungseinrichtung penetrierbar sind zur zuverlässigen Zufuhr der Flüssigkeitsextraktion der Substanz zur Zubereitung des Getränks.This has the advantage that the capsule body and the membrane can be penetrated with the same penetration device for the reliable supply of the liquid extraction of the substance for the preparation of the drink.

Alternativ ist es selbstverständlich auch denkbar, dass nur der Kapselkörper mittels der Penetrierungseinrichtung durchstochen wird und die Membran durch den Druck der zugeführten Flüssigkeit im Betrieb aufreisst. Hierzu können insbesondere Schwächungsbereiche an der Membran angeordnet sein, so dass diese im Betrieb leichter aufreisst.Alternatively, it is of course also conceivable that only the capsule body is pierced by means of the penetration device and the membrane is torn open by the pressure of the supplied liquid during operation. For this purpose, areas of weakness in particular can be arranged on the membrane so that it tears open more easily during operation.

Bevorzugt ist die Membran aus Aluminium und/oder einem Laminat hergestellt. Insbesondere ist das Laminat im Wesentlichen plastisch verformbar.The membrane is preferably made of aluminum and / or a laminate. In particular, the laminate is essentially plastically deformable.

Dies hat den Vorteil der Anpassbarkeit der Kapsel an die entsprechende Vorrichtung zur Zubereitung des Lebensmittels, in der diese eingesetzt werden soll zur Gewährleistung einer zuverlässigen Zuführung der Flüssigkeit in die geschlossene Kammer zur Extraktion der Substanz. Insbesondere die Verwendung von Aluminium ist vorteilhaft, da sich beim Durchstechen die Aluminiummembran im Wesentlichen plastisch verformt und somit zuverlässig im Aluminium die Penetrierungsöffnung gebildet werden kann zur Zuführung der Flüssigkeit. Alternativ kann die Membran auch aus einem Laminat, das heisst einem Mehrschichtmaterial, gebildet werden, das insbesondere plastisch verformbar ist zur zuverlässigen Bildung der Penetrierungsöffnung.This has the advantage that the capsule can be adapted to the corresponding device for preparing the food in which it is to be used to ensure reliable supply of the liquid into the closed chamber for extraction of the substance. In particular, the use of aluminum is advantageous since the aluminum membrane is essentially plastically deformed when it is pierced and is therefore reliable The penetration opening can be formed in the aluminum for the supply of the liquid. Alternatively, the membrane can also be formed from a laminate, that is to say a multi-layer material, which in particular is plastically deformable in order to reliably form the penetration opening.

Beispielsweise kann das Laminat aus zwei Schichten von Polymeren oder auch aus einer Schicht Aluminium in Kombination mit einer Schicht aus einem Polymer gebildet werden entsprechend den Anforderungen an die Kapsel.For example, the laminate can be formed from two layers of polymers or also from a layer of aluminum in combination with a layer of a polymer, depending on the requirements of the capsule.

Bevorzugt sind der Kapselkörper und der Deckel aus einem im Wesentlichen luftundurchlässigen Material hergestellt. Dies hat den Vorteil, dass die in der Kapsel aufgenommene Substanz im Wesentlichen luftdicht verschlossen ist, so dass eine aromadichte Kapsel gebildet wird und keine zusätzliche äussere Hülle benötigt wird, was die Herstellungskosten verringert und die Handhabung der Kapsel bei Verwendung durch einen Bediener vereinfacht.The capsule body and the lid are preferably made from a substantially air-impermeable material. This has the advantage that the substance received in the capsule is essentially hermetically sealed, so that an aroma-tight capsule is formed and no additional outer shell is required, which reduces manufacturing costs and simplifies handling of the capsule when used by an operator.

Bevorzugt ist der Boden der Kapsel für die Durchleitung der Flüssigkeit durch die geschlossene Kammer mit einer ausserhalb der Kapsel angeordneten Penetrierungseinrichtung an einen Penetrationsbereich des Bodens penetrierbar. Der Boden weist dabei einen Versteifungsbereich auf, wobei insbesondere ein zentraler Bereich des Bodens als Penetrationsbereich ausgebildet ist. Der Versteifungsbereich ist um den Penetrationsbereich angeordnet. Die Anordnung des Versteifungsbereichs ist insbesondere rotationssymmetrisch um den Penetrationsbereich. Der Versteifungsbereich ist als zumindest eine abschnittsweise Vertiefung im Wesentlichen in Umfangsrichtung im Boden ausgebildet.The base of the capsule can preferably be penetrated to a penetration area of the base for the passage of the liquid through the closed chamber with a penetration device arranged outside the capsule. The floor has a stiffening area, in particular a central area of the floor being designed as a penetration area. The stiffening area is arranged around the penetration area. The arrangement of the stiffening area is in particular rotationally symmetrical around the penetration area. The stiffening area is designed as at least one section-wise recess essentially in the circumferential direction in the base.

Unter einer Vertiefung im Boden wird eine Vertiefung auf einer Aussenseite der Kapsel verstanden und zwar als integraler Bestandteil des Bodens.A recess in the base is understood to mean a recess on an outside of the capsule, specifically as an integral part of the base.

Unter einer abschnittsweisen Vertiefung im Boden im Wesentlichen in Umfangsrichtung wird verstanden, dass die Vertiefung in Umfangsrichtung eine Ausdehnung hat, die kleiner als 360° ist.A section-wise indentation in the base essentially in the circumferential direction is understood to mean that the indentation has an extent in the circumferential direction which is smaller than 360 °.

Unter einem Penetrationsbereich wird im Sinne der vorliegenden Anmeldung ein Bereich des Bodens verstanden, der von der Penetriereinrichtung penetriert wird.In the context of the present application, a penetration area is understood to mean an area of the floor that is penetrated by the penetration device.

Unter einem Versteifungsbereich wird im Sinne der vorliegenden Anmeldung ein Bereich des Bodens verstanden, in dem die Vertiefungen zur Versteifung angeordnet sind.In the context of the present application, a stiffening area is understood to mean an area of the floor in which the indentations for stiffening are arranged.

Die Anordnung des Versteifungsbereichs um den Penetrationsbereich hat nun den Vorteil, dass der Boden zuverlässig durch in handelsüblichen Vorrichtungen zur Zubereitung eines Lebensmittels angeordnete Penetriereinrichtungen penetrierbar ist, so dass die Getränkeherstellung ermöglicht wird. Zudem ist die Kapsel auch kostengünstig herstellbar, da der Versteifungsbereich als integraler Bestandteil der Kapsel ausgebildet ist und die Kapsel somit beispielsweise mittels eines Tiefziehverfahrens herstellbar ist. Somit können Kapseln aus Kunststoff in handelsüblichen Vorrichtungen verwendet werden, die ohne Anordnung eines Versteifungsbereichs nicht immer in den Vorrichtungen zuverlässig penetriert werden.The arrangement of the stiffening area around the penetration area now has the advantage that the base can be reliably penetrated by penetration devices arranged in commercially available devices for the preparation of a food, so that the production of beverages is made possible. In addition, the capsule can also be manufactured inexpensively, since the stiffening area is designed as an integral part of the capsule and the capsule can thus be manufactured, for example, by means of a deep-drawing process. Thus, capsules made of plastic can be used in commercially available devices which, without the provision of a stiffening area, cannot always be reliably penetrated in the devices.

Bevorzugt weist die Vertiefung wenigstens zwei zueinander geneigte Wandabschnitte auf. Insbesondere sind die Wandabschnitte in einer entlang der Längsachse des Kapselkörpers verlaufenden Schnittebene durch die Vertiefung zueinander geneigt.The recess preferably has at least two wall sections which are inclined towards one another. In particular, the wall sections are inclined to one another in a sectional plane running along the longitudinal axis of the capsule body through the recess.

Diese Anordnung von zwei zueinander geneigten Wandabschnitten als Vertiefung hat sich in der Praxis als vorteilhaft für die Bildung des Versteifungsbereichs gezeigt, wobei diese Vertiefung weiterhin einfach und kostengünstig beispielsweise mit einem Tiefziehverfahren herstellbar ist.This arrangement of two mutually inclined wall sections as a recess has been shown in practice to be advantageous for the formation of the stiffening area, this recess still being easy and inexpensive to produce, for example with a deep-drawing process.

Ein weiterer Aspekt der vorliegenden Erfindung betrifft einen Kapselkörper für eine Kapsel wie oben beschrieben.Another aspect of the present invention relates to a capsule body for a capsule as described above.

Ein zusätzlicher Aspekt der vorliegenden Erfindung betrifft ein Verfahren zur Herstellung eines Kapselkörpers wie vorstehend beschrieben. Dieses Verfahren umfasst den Schritt eines Tiefziehens des Kapselkörpers. Anschliessend und/oder gleichzeitig mit dem Tiefziehen erfolgt ein Schneiden von zumindest einem Schlitz. Der Schritt des Schneidens erfolgt derart, dass im Wesentlichen kein Materialabtrag erfolgt. Insbesondere berühren sich die gegenüberliegenden Kanten des Schlitzes zumindest abschnittsweise, bevorzugt auf zumindest 90 %, besonders bevorzugt auf zumindest 95 % und ganz besonders bevorzugt auf 100 % einer Länge L des Schlitzes.An additional aspect of the present invention relates to a method for producing a capsule body as described above. This method comprises the step of deep-drawing the capsule body. Subsequently and / or simultaneously with the deep drawing, at least one slot is cut. The cutting step takes place in such a way that essentially no material is removed. In particular, the opposite edges of the slot touch at least in sections, preferably at least 90%, particularly preferably at least 95% and very particularly preferably 100% of a length L of the slot.

Das Erzeugen von zumindest einem Schlitz in dem tiefgezogenen Kapselkörper hat den Vorteil, dass der Schlitz mit einer derartigen Grösse kostengünstig herstellbar sind, sodass im Wesentlichen keine Substanz aus der Kapsel gelangen kann. Insbesondere ist das Verfahren der Erzeugung von zumindest einem Schlitzen wesentlich kostengünstiger als die Erzeugung von Löchern mit einem entsprechend kleinen Durchmesser in dem Kapselkörper. Der zumindest eine Schlitz ist insbesondere nach dem Abfüllen von Substanz und Verschliessen des Kapselkörpers mit einem Deckel erzeugbar.The creation of at least one slot in the deep-drawn capsule body has the advantage that the slot can be produced inexpensively with such a size that essentially no substance can get out of the capsule. In particular, the method of producing at least one slot is significantly more cost-effective than producing holes with a correspondingly small diameter in the capsule body. The at least one slot can be produced with a lid, in particular after the substance has been filled in and the capsule body has been closed.

Bevorzugt wird eine im Wesentlichen luftundurchlässige Schicht abschnittsweise und/oder vollflächig aufgebracht. Insbesondere wird die Schicht an der Seitenwand und/oder dem Boden aufgebracht.A substantially air-impermeable layer is preferably applied in sections and / or over the entire surface. In particular, the layer is applied to the side wall and / or the floor.

Ein weiterer Aspekt der vorliegenden Erfindung betrifft ein System umfassend eine mit einer Substanz gefüllten Kapsel, wie vorstehend beschrieben und eine Getränkeherstellungsvorrichtung. Die Getränkeherstellungsvorrichtung weist einen Kapselhalter auf zur Aufnahme der Kapsel. Die Getränkeherstellungsvorrichtung weist zudem eine Einrichtung zur Zuführung einer Flüssigkeit in die Kapsel zur Extraktion der Substanz zur Herstellung eines Getränks auf, wobei das Getränk durch einen Deckel der Kapsel abführbar ist. Schliesslich weist die Getränkeherstellungsvorrichtung vorteilhaft auch noch eine Penetrierungseinrichtung auf.Another aspect of the present invention relates to a system comprising a capsule filled with a substance, as described above, and a beverage production device. The beverage production device has a capsule holder for receiving the capsule. The beverage production device also has a device for feeding a liquid into the capsule for extracting the substance for producing a drink, the drink being able to be removed through a lid of the capsule. Finally, the beverage production device advantageously also has a penetration device.

Die Getränkeherstellungsvorrichtung weist zudem insbesondere eine Einrichtung zur Abführung des Getränks auf, beispielsweise in einen Trinkbehälter.The beverage production device also has, in particular, a device for discharging the beverage, for example into a drinking container.

Weitere Merkmale und Vorteile der Erfindung werden nachfolgend anhand von Ausführungsbeispielen zum besseren Verständnis näher erläutert, ohne das die Erfindung auf die Ausführungsbeispiele zu beschränken ist. Es zeigen:

In Figur 1 ist eine Draufsicht auf den Boden 4 eines erfindungsgemässen Kapselkörpers 2 dargestellt. Der Kapselkörper 2 weist einen Flansch 22 und eine Seitenwand 3 auf. Im Boden 4 sind vier Schlitze 8 in einer Ruhestellung, dass heisst in einer geschlossenen Position, dargestellt. Es wird keine Kraft auf den Kapselkörper 2 ausgeübt.In Figure 1 a top view of the base 4 of a capsule body 2 according to the invention is shown. The capsule body 2 has a flange 22 and a side wall 3. In the bottom 4, four slots 8 are shown in a rest position, that is to say in a closed position. No force is exerted on the capsule body 2.

In Figur 2 ist eine Draufsicht auf einen alternativen erfindungsgemässen Kapselkörper 2 dargestellt. Gleiche Referenzzeichen bezeichnen gleiche Merkmale in allen Figuren und werden deshalb nur bei Bedarf erneut erläutert.In Figure 2 a plan view of an alternative capsule body 2 according to the invention is shown. The same reference symbols denote the same features in all figures and are therefore only explained again when necessary.

Im Boden 4 des Kapselkörpers 2 sind zwei Schlitze 8 angeordnet, die sich etwa im geometrischen Mittelpunkt des Bodens kreuzen. Zur Abdichtung der Schlitze 8 ist der Kapselkörper 2, dass heisst die Seitenwand 3 und der Boden 4, vollflächig mit einer im Wesentlichen luftundurchlässigen Schicht 10 verschlossen. Diese Schicht 10 ist als lösbare und luftundurchlässige lebensmitteltaugliche Schicht bestehend im Wesentlichen aus Zucker ausgebildet.In the base 4 of the capsule body 2, two slots 8 are arranged, which intersect approximately in the geometric center of the base. To seal off the slots 8, the capsule body 2, that is to say the side wall 3 and the bottom 4, has a full surface with a substantially air-impermeable layer 10 closed. This layer 10 is designed as a detachable and air-impermeable food-grade layer consisting essentially of sugar.

In Figur 3 ist ein weiterer alternativer erfindungsgemässer Kapselkörper 2 mit Schlitzen 8 dargestellt. Die Schlitze 8 sind mit einer Aluminiumschicht 10, welche abschnittsweise den Boden 4 bedeckt, abgedichtet.In Figure 3 a further alternative capsule body 2 according to the invention with slots 8 is shown. The slots 8 are sealed with an aluminum layer 10 which covers the base 4 in sections.

In Figur 4 ist eine Draufsicht eines weiteren erfindungsgemässen Kapselkörpers 2 dargestellt. Die Schlitze 8 im Boden sind mit einer löslichen Polymerschicht 10 verschlossen, die vollflächig den Boden 4 bedeckt.In Figure 4 a top view of a further capsule body 2 according to the invention is shown. The slots 8 in the base are closed with a soluble polymer layer 10 which covers the entire surface of the base 4.

In Figur 5 ist eine Draufsicht eines weiteren erfindungsgemässen Kapselkörpers 2 dargestellt mit Schlitzen 8 im Boden 4 und der Seitenwand 3. Eine Schicht zur Verschliessung der Schlitze 8 ist auf der Innenseite, dass heisst in der Kammer des Kapselkörpers aufgebracht, in dem die Substanz zur Herstellung eines Getränks aufgenommen wird. Diese Schicht ist in der vorliegenden Figur nicht sichtbar.In Figure 5 is a plan view of a further inventive capsule body 2 shown with slots 8 in the bottom 4 and the side wall 3. A layer for closing the slots 8 is applied on the inside, that is, in the chamber of the capsule body, in which the substance for making a drink is received will.

In Figur 6 ist eine Draufsicht eines weiteren erfindungsgemässen Kapselkörpers mit gekrümmten Schlitzen dargestellt.In Figure 6 a top view of a further capsule body according to the invention with curved slots is shown.

Figur 7 zeigt eine Draufsicht eines weiteren erfindungsgemässen Kapselkörpers 2 mit Schlitzen 8 in der Seitenwand, welche mit einer löslichen und lebensmitteltauglichen Schicht 10 verschlossen sind. Die Schicht 10 ist auf der Seitewand 3 vollflächig aufgebracht. Figure 7 shows a top view of a further capsule body 2 according to the invention with slots 8 in the side wall, which are closed with a soluble and food-grade layer 10. The layer 10 is applied over the entire surface of the side wall 3.

In Figur 8 ist eine weitere Draufsicht einer alternativen Ausführungsform des Kapselkörpers 2 dargestellt umfassend zwei Schlitze 8 im Boden.
