If the one-dimensional machine-readable code runs in a defined direction relative to the tab or its position, the orientation of the code on the capsule in relation to the reading device on the beverage preparation device is also determined. This makes reading the code easier. In one possible orientation, the straight line along which the code extends can, for example, run through the tab.

Description

Die vorliegende Erfindung betrifft eine Kapsel, insbesondere zur Zubereitung eines Getränkeproduktes, ein Verfahren zum Herstellen mehrerer Kapseln sowie ein Getränkezubereitungssystem umfassend eine derartige Kapsel.The present invention relates to a capsule, in particular for preparing a beverage product, a method for producing several capsules and a beverage preparation system comprising such a capsule.

Getränkezubereitungssysteme für die Zubereitung von Kaffee oder Tee sind heutzutage insbesondere in Privathaushalten weit verbreitet. Für die jeweiligen Systeme sind Portionsverpackungen, insbesondere Kapseln, mit verschiedenen Kaffee- oder Teesorten im Handel erhältlich. Die Getränkezubereitung erfolgt in der Regel durch Einlegen einer entsprechenden Kapsel in eine dafür vorgesehene Vorrichtung und Extraktion oder Auflösen einer in der Kapsel enthaltenen Substanz durch Durchleiten einer Flüssigkeit. Bei der Substanz 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. Nach erfolgter Getränkeherstellung wird die Kapsel aus der Vorrichtung entfernt und in der Regel entsorgt.Beverage preparation systems for preparing coffee or tea are now particularly widespread in private households. Portion packaging, especially capsules, with different types of coffee or tea are commercially available for the respective systems. The beverage is usually prepared by inserting a corresponding capsule into a device provided for this purpose and extracting or dissolving a substance contained in the capsule by passing a liquid through it. In many cases the substance is roasted and ground coffee powder, but sometimes it is also dried tea leaves. However, soluble products in general or concentrates are also possible. After the beverage has been produced, the capsule is removed from the device and usually disposed of.

Damit mit ein und derselben Vorrichtung Kapseln unterschiedlichen Inhaltes (bspw. verschiedene Kaffee- oder Teesorten, lösliche Produkte, oder Konzentrate) verwendet werden können, besteht das Bedürfnis, die Betriebsparameter der Vorrichtung in Abhängigkeit des jeweils verwendeten Produktes einzustellen. Dies betrifft beispielsweise die durchzuleitende Menge an Flüssigkeit, die Extraktionstemperatur oder auch die Extraktionsgeschwindigkeit. Aus Sicherheitsgründen soll darüber hinaus verhindert werden, dass die Maschine mit nicht kompatiblen Kapseln betrieben wird.So that capsules with different contents (e.g. different types of coffee or tea, soluble products, or concentrates) can be used with one and the same device, there is a need to set the operating parameters of the device depending on the product used. This concerns, for example, the amount of liquid to be passed through, the extraction temperature or the extraction speed. For safety reasons, it should also be prevented that the machine is operated with incompatible capsules.

Zu diesem Zweck ist es grundsätzlich bereits bekannt, eine Portionsverpackung mit einer Kennung und eine Vorrichtung mit Mitteln zum Erfassen der Kennung auszurüsten. So beschreibt die CH 707374 A1 ein Getränkeherstellungssystem mit Kapseln, auf deren Deckeln jeweils ein maschinenlesbarer Code angeordnet ist, der sich aus konzentrischen Kreisen zusammensetzt. Die entsprechende Getränkezubereitungsmaschine weist ein Lesegerät für den Code auf, das mit einer Steuervorrichtung verbunden ist, mit welcher in Abhängigkeit vom eingelesenen Code die Betriebsparameter der Getränkezubereitungsmaschine einstellbar sind. Das besagte Getränkeherstellungssystem erlaubt damit eine benutzerfreundliche Erkennung der jeweils verwendeten Kapselsorte. Aufgrund der rotationssymmetrischen Ausgestaltung des Codes auf dem Kapseldeckel ist ein maschinelles Lesen desselben unabhängig von der relativen Orientierung von Kapsel und Lesegerät möglich.For this purpose, it is basically already known to equip a portion packaging with an identifier and a device with means for detecting the identifier. That's how it describes CH 707374 A1 a beverage production system with capsules, each of which has a machine-readable code on the lid, which is made up of concentric circles. The corresponding beverage preparation machine has a reading device for the code, which is connected to a control device with which the operating parameters of the beverage preparation machine can be adjusted depending on the code read. The beverage production system in question allows user-friendly recognition of the type of capsule used. Due to the rotationally symmetrical design of the code on the capsule lid, it can be read by machine regardless of the relative orientation of the capsule and the reading device.

Beim beschriebenen System besteht allerdings das Problem, dass ein erfolgreiches Erfassen des Codes stark von der relativen Positionierung von Kapsel und Lesegerät abhängt. So ist es insbesondere bei optischen Lesegeräten, welche den Code lediglich in einer Dimension erfassen, erforderlich, dass der Lesevorgang entlang einer Linie verläuft, die durch das Zentrum des durch konzentrische Kreise gebildeten Codes verläuft. Dies erfordert in der Regel nicht nur eine exakte Positionierung der Kapsel vor dem Lesegerät sondern auch ein präzises Anbringen des mit dem Code bedruckten Deckels am Kapselkörper. Ist der Code entlang der Leserichtung des Lesegerätes verschmutzt, kann der Lesevorgang gestört sein. Darüber hinaus ist aufgrund der rotationssymmetrischen Ausgestaltung des Codes dessen Wortlänge im Verhältnis zu seiner Breite auf nur die Hälfte beschränkt.However, the problem with the system described is that successful capture of the code depends heavily on the relative positioning of the capsule and the reader. In particular with optical reading devices, which only detect the code in one dimension, it is necessary that the reading process runs along a line that runs through the center of the code formed by concentric circles. This usually requires not only precise positioning of the capsule in front of the reader but also precise attachment of the lid printed with the code to the capsule body. If the code is dirty along the reading direction of the reading device, the reading process may be disrupted. In addition, due to the rotationally symmetrical design of the code, its word length is limited to only half of its width.

Weitere Anordnungen von maschinenlesbaren Codierungen auf einer Kapsel sind beispielsweise in WO 2016009258 A1 , WO 2015055849 A1 , EP 1790470 A1 und EP 2572609 A1 gezeigt. Allen gezeigten Codierungen ist gemeinsam, dass bei einer Verschmutzung des Codes oder der entsprechenden Lesevorrichtung der Lesevorgang gestört ist und der Code nicht korrekt ausgelesen werden kann.Further arrangements of machine-readable codes on a capsule are, for example, in WO 2016009258 A1 , WO 2015055849 A1 , EP 1790470 A1 and EP 2572609 A1 shown. What all of the codes shown have in common is that if the code or the corresponding reading device is dirty, the reading process is disrupted and the code cannot be read correctly.

Es ist daher die Aufgabe der vorliegenden Erfindung, die Nachteile im Stand der Technik zu überwinden. Insbesondere ist es eine Aufgabe der Erfindung, eine Kapsel und ein Getränkezubereitungssystem der oben genannten Art zu schaffen, bei denen die Zuverlässigkeit des maschinellen Lesens des auf der Kapsel angebrachten Codes verbessert ist.It is therefore the object of the present invention to overcome the disadvantages in the prior art. In particular, it is an object of the invention to provide a capsule and a beverage preparation system of the above-mentioned type in which the reliability of the machine reading of the code attached to the capsule is improved.

Diese Aufgabe wird durch eine Kapsel gelöst, welche die Merkmale in Anspruch 1 aufweist. Die besagte Kapsel, insbesondere zur Zubereitung eines Getränkeproduktes, umfasst einen mit einem Deckel abgedeckten, vorzugweise rotationssymmetrisch ausgebildeten Kapselkörper. Auf dem Deckel ist ein eindimensional-maschinenlesbarer Code angebracht, insbesondere gedruckt, der sich entlang einer durch den Flächenschwerpunkt des Deckels verlaufenden Geraden erstreckt. Der Code ist in einer Leserichtung senkrecht zur Geraden maschinenlesbar.This task is solved by a capsule which has the features in claim 1. The capsule in question, in particular for preparing a beverage product, comprises a capsule body covered with a lid and preferably designed to be rotationally symmetrical. A one-dimensional machine-readable code is attached to the lid, in particular printed, which extends along a straight line running through the center of gravity of the lid. The code is machine readable in a reading direction perpendicular to the straight line.

Darunter, dass sich der Code entlang der Geraden erstreckt, ist im vorliegenden Zusammenhang zu verstehen, dass der Code eine Ausdehnung in Richtung der Geraden hat und die Gerade auf oder unmittelbar neben dem Code verläuft.In the present context, the fact that the code extends along the straight line means that the code has an extension in the direction of the straight line and the straight line runs on or immediately next to the code.

Durch diese Ausgestaltung des Codes und seine Anordnung auf der Kapsel ist das maschinelle Lesen desselben deutlich weniger störungsanfällig. Dies trifft einerseits in Bezug auf die relative Positionierung der Kapsel und des Lesegerätes zu. Andererseits kann der Code an mehreren Stellen entlang der Geraden ausgelesen werden, wodurch im Falle von Verschmutzungen auf dem Deckel der Code dennoch erkannt werden kann. Dies ist insbesondere vorteilhalft, wenn das Lesegerät nur zum eindimensionalen Lesen geeignet ist. Darüber hinaus können die Toleranzen in Bezug auf die Anbringung des Codes auf der Kapsel deutlich grösser sein. Nicht zuletzt kann auch die gesamte Breite des Codes für dessen Wortlänge genutzt werden.This design of the code and its arrangement on the capsule means that machine reading of the code is significantly less prone to errors. On the one hand, this applies to the relative positioning of the capsule and the reading device. on the other hand The code can be read at several points along the straight line, which means that the code can still be recognized if the lid is dirty. This is particularly advantageous if the reading device is only suitable for one-dimensional reading. In addition, the tolerances regarding the placement of the code on the capsule can be significantly larger. Last but not least, the entire width of the code can be used for its word length.

Neben eigentlichen Druckverfahren, die üblicherweise auf Pigmentauftrag basieren, kommt für das Anbringen des eindimensional-maschinenlesbaren Codes auch ein Laserbeschriftungsverfahren in Betracht, bei dem das zu beschriftende Material selbst verändert wird.In addition to actual printing processes, which are usually based on pigment application, a laser marking process can also be used to apply the one-dimensional machine-readable code, in which the material to be marked is itself changed.

Der Code ist entlang des gesamten auf den Deckel verlaufenden Abschnitts der Geraden maschinenlesbar. Dadurch können die vorangehend beschriebenen Vorteile maximiert werden. Alternativ ist der Code entlang mehrerer auf dem Deckel verlaufenden unterbrochenen Abschnitte der Geraden maschinenlesbar. Damit können die oben beschriebenen Vorteile, noch immer erzielt werden.The code is machine readable along the entire section of the straight line running onto the lid. This allows the advantages described above to be maximized. Alternatively, the code is machine-readable along several interrupted sections of the straight line running on the lid. This means that the advantages described above can still be achieved.

Der Code kann sich mittig entlang der Geraden erstrecken. Dies ermöglicht die Verwendung eines Codes mit grösserer Wortlänge. Darunter, dass sich der Code mittig entlang der Geraden erstreckt, ist im vorliegenden Zusammenhang zu verstehen, dass die Gerade durch den Flächenschwerpunkt der vom Code belegten Fläche verläuft.The code can extend in the middle along the straight line. This allows the use of a code with a longer word length. In the present context, the fact that the code extends centrally along the straight line means that the straight line runs through the center of gravity of the area occupied by the code.

Beim eindimensional-maschinenlesbaren Code handelt es sich um einen Strichcode. Der Strichcode kann einzeilig oder mehrzeilig sein, jedoch ist der Code stets in einer Leserichtung senkrecht zur Geraden lesbar. Der Strichcode kann genormt sein. So kann es sich beispielsweise um einen Handelsstrichcode (EAN, UPC, IAN, JAN), einen 2/5-Code, einen Code 39, einen Code 93, eine Codabar, oder einen Code 128 handeln. Derartige Codes sind im Stand der Technik weit verbreitet. Sie weisen im Zusammenhang mit ihrer Erfassung eine hohe Zuverlässigkeit auf, und es steht eine Reihe von verschiedenen Systemen zur Verfügung, mit denen sie ausgelesen werden können. Der Strichcode kann überquadratisch sein, wobei darunter verstanden wird, dass dieser senkrecht zu seiner Leserichtung eine grössere Ausdehnung aufweist als in seiner Leserichtung. Damit ist es möglich, mit zwei zu einander im rechten Winkel stehenden Scannern den Strichcode in jeder Orientierung zu lesen.The one-dimensional machine-readable code is a barcode. The barcode can be single-line or multi-line, but the code can always be read in a reading direction perpendicular to the straight line. The barcode can be standardized. So it can for example, a commercial barcode (EAN, UPC, IAN, JAN), a 2/5 code, a Code 39, a Code 93, a Codabar, or a Code 128. Such codes are widely used in the prior art. They have a high level of reliability in terms of their detection and a number of different systems are available with which they can be read. The barcode can be oversquare, which means that it has a greater extent perpendicular to its reading direction than in its reading direction. This makes it possible to read the barcode in any orientation using two scanners positioned at right angles to each other.

Es versteht sich allerdings von selbst, dass es sich beim eindimensional-maschinenlesbaren Code nicht um einen herkömmlichen Strichcode handeln muss. So kann der Code beispielsweise beliebige Formen, unter anderem auch eine Wellenform aufweisen. Darüber hinaus kann der Code auch durch eine Aussenkontur maskiert sein.However, it goes without saying that the one-dimensional machine-readable code does not have to be a conventional barcode. For example, the code can have any shape, including a waveform. In addition, the code can also be masked by an outer contour.

Der eindimensional-maschinenlesbare Code kann von zumindest einem weiteren eindimensional-maschinenlesbaren Code gekreuzt werden. Der weitere eindimensional-maschinenlesbare Code kann sich entlang einer zweiten Geraden, welche insbesondere senkrecht zur ersten Geraden verläuft, erstrecken. Allerdings muss die zweite Gerade nicht exakt senkrecht zur ersten Geraden verlaufen. So kann ein Schnittwinkel zwischen der ersten und der zweiten Geraden von 80° bis 90° vorteilhaft sein. Die zweite Gerade kann bevorzugt durch den Flächenschwerpunkt des Deckels verlaufen. Durch diese Ausgestaltung der Kapsel können mit den beiden sich kreuzenden Codes verschiedene Informationen auf dem Deckel angebracht und selektiv ausgelesen werden. Allerdings ist es auch möglich, dass die beiden Codes identisch sind. Insbesondere wenn die beiden Geraden senkrecht zueinander verlaufen, ist es möglich, mit nur einem Scanner die in den beiden Codes enthaltene Information unabhängig von der Orientierung der Kapsel zu lesen.The one-dimensional machine-readable code can be crossed by at least one further one-dimensional machine-readable code. The further one-dimensional machine-readable code can extend along a second straight line, which runs in particular perpendicular to the first straight line. However, the second straight line does not have to be exactly perpendicular to the first straight line. An intersection angle between the first and second straight lines of 80° to 90° can be advantageous. The second straight line can preferably run through the center of gravity of the cover. This design of the capsule allows different information to be attached to the lid and selectively read out using the two crossing codes. However, it is also possible that the two codes are identical. Especially if the two straight lines run perpendicular to each other, it is possible to read the information contained in the two codes with just one scanner, regardless of the orientation of the capsule.

Der Deckel der Kapsel kann eine in seiner Ebene angeordnete Lasche aufweisen. Die Lasche kann es einem Nutzer ermöglichen, den Deckel leichter von der Kapsel zu entfernen, um an deren Inhalt zu gelangen, falls dies erforderlich ist. Allerdings kann die Lasche auch als Griffelement zur leichteren Handhabung der gesamten Kapsel dienen. Darüber hinaus kann die Lasche die Funktion erfüllen, dass die Kapsel nur in einer bestimmten Orientierung in eine Getränkezubereitungsvorrichtung eingesetzt werden kann. Wenn der eindimensional-maschinenlesbare Code in einer festgelegten Richtung relativ zur Lasche bzw. deren Position verläuft, ist damit auch die Orientierung des Codes an der Kapsel im Verhältnis zum Lesegerät an der Getränkezubereitungsvorrichtung festgelegt. Dies erleichtert das Auslesen des Codes. In einer möglichen Orientierung kann die Gerade, entlang welcher sich der Code erstreckt, beispielsweise durch die Lasche verlaufen.The lid of the capsule can have a tab arranged in its plane. The tab may allow a user to more easily remove the lid from the capsule to access its contents if necessary. However, the tab can also serve as a grip element to make handling the entire capsule easier. In addition, the tab can fulfill the function that the capsule can only be inserted into a beverage preparation device in a certain orientation. If the one-dimensional machine-readable code runs in a defined direction relative to the tab or its position, the orientation of the code on the capsule in relation to the reading device on the beverage preparation device is also determined. This makes reading the code easier. In one possible orientation, the straight line along which the code extends can, for example, run through the tab.

Alternativ oder zusätzlich zu einer am Deckel angeordneten Lasche kann der Kapselkörper allerdings auch einen Fortsatz, insbesondere in Form einer Lasche, aufweisen. Auch dieser Fortsatz kann zur vereinfachten Handhabung der Kapsel als Griffelement dienen. Darüber hinaus kann ähnlich wie bei der Lasche am Deckel durch den Fortsatz am Kapselkörper die relative Orientierung zwischen dem Code und dem Lesegerät beim Einlegen der Kapsel in die Aufnahme einer Getränkezubereitungsvorrichtung festgelegt werden.Alternatively or in addition to a tab arranged on the lid, the capsule body can also have an extension, in particular in the form of a tab. This extension can also serve as a grip element to simplify handling of the capsule. In addition, similar to the tab on the lid, the extension on the capsule body can be used to determine the relative orientation between the code and the reading device when inserting the capsule into the receptacle of a beverage preparation device.

Es versteht sich allerdings von selbst, dass die relative Orientierung zwischen dem Code und dem Lesegerät auch durch eine an die Aufnahme der Getränkezubereitungsvorrichtung angepasste Form des Kapselkörpers festgelegt werden kann.However, it goes without saying that the relative orientation between the code and the reading device is also determined by an the shape of the capsule body adapted to the holder of the beverage preparation device can be determined.

Zumindest ein eindimensional-maschinenlesbarer Code kann Parameter zur Zubereitung des Getränkeproduktes enthalten und/oder damit verknüpft sein. Die Parameter können insbesondere ausgewählt sein aus einer Liste bestehend aus Temperatur, Volumen, Durchflussrate und Zusammensetzung einer in die Kapsel einzuleitenden Flüssigkeit. Dadurch können bei Einlegen der Kapsel in eine Getränkezubereitungsvorrichtung deren Betriebsparameter angepasst werden. Dies ermöglicht es, mit der Getränkezubereitungsvorrichtung verschiedenartige Getränke zuzubereiten. Allerdings kann der eindimensional-maschinenlesbare Code nicht nur Parameter enthalten und/oder damit verknüpft sein, die während der Getränkezubereitung konstant bleiben. Ebenfalls ist es möglich, dass der zumindest eine eindimensional-maschinenlesbare Code eine Getränkezubereitungsroutinen enthält und/oder damit verknüpft ist. So kann die Durchflussrate durch die Kapsel während einer Kaffeezubereitung beispielsweise variieren: Erst 100%, dann 0% (Vorbrühen), später 60%. Dies ermöglicht insbesondere die Herstellung eines qualitativ hochwertigeren Kaffeegetränkes.At least one one-dimensional machine-readable code can contain and/or be linked to parameters for preparing the beverage product. The parameters can in particular be selected from a list consisting of temperature, volume, flow rate and composition of a liquid to be introduced into the capsule. This means that when the capsule is inserted into a beverage preparation device, its operating parameters can be adjusted. This makes it possible to prepare various types of drinks with the beverage preparation device. However, the one-dimensional machine-readable code cannot only contain and/or be linked to parameters that remain constant during beverage preparation. It is also possible for the at least one one-dimensional machine-readable code to contain and/or be linked to a beverage preparation routine. For example, the flow rate through the capsule can vary while making coffee: first 100%, then 0% (pre-brewing), later 60%. In particular, this enables the production of a higher quality coffee drink.

Der Kapselkörper kann entlang seiner Längsmittelachse gestaucht oder gedehnt proportioniert sein. Dadurch kann die Form des Kapselkörpers der jeweiligen Anwendung, insbesondere hinsichtlich des aufzunehmenden Substanzvolumens und/oder des Druckes der einzuleitenden Flüssigkeit, beispielsweise bei einer Extraktion des Kapselinhaltes, angepasst werden. Der Kapselkörper kann mit einem Spritzguss- oder Tiefziehverfahren hergestellt sein. Während der Kapselkörper durch Spritzguss in deutlich komplexeren Formen ausgeführt werden kann, ist es durch Tiefziehverfahren möglich, Kapselkörper mit besonders hoher Sauerstoff- und/oder Aromadichtigkeit herzustellen. Allerdings ist Sauerstoff- und/oder Aromadichtigkeit nicht auf durch ein Tiefziehverfahren hergestellte Kapseln beschränkt. Der den Kapselkörper abdeckende Deckel kann aus einer Kunststofffolie und/oder Metallfolie bestehen. Dadurch ist es möglich die Charakteristika des Deckels hinsichtlich Sauerstoff- und/oder Aromadichtigkeit, Reissfestigkeit und Bedruckbarkeit den jeweiligen Anforderungen anzupassen.The capsule body can be compressed or stretched along its longitudinal central axis. As a result, the shape of the capsule body can be adapted to the respective application, in particular with regard to the volume of substance to be absorbed and/or the pressure of the liquid to be introduced, for example when extracting the capsule contents. The capsule body can be manufactured using an injection molding or deep-drawing process. While the capsule body can be made into significantly more complex shapes by injection molding, it is possible to produce capsule bodies with particularly high oxygen and/or aroma tightness using deep-drawing processes. However, oxygen and/or aroma impermeability is not limited to capsules produced by a deep-drawing process. The lid covering the capsule body can consist of a plastic film and/or metal film. This makes it possible to adapt the characteristics of the lid in terms of oxygen and/or aroma tightness, tear resistance and printability to the respective requirements.

Wie bereits erwähnt, kann der Kapselkörper losgelöst vom Herstellungsverfahren sauerstoff- und/oder aromadicht ausgebildet sein. 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- bzw. 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.As already mentioned, the capsule body can be designed to be oxygen-tight and/or aroma-tight, independent of the manufacturing process. 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. This means that aging of the starting substance, for example coffee powder, due to oxidation can be avoided. An oxygen-tight capsule is usually also aroma-tight. Accordingly, leakage of flavoring substances contained in the starting substance during storage within the capsule is essentially prevented. Oxygen and aroma impermeability is required in order to achieve a minimum shelf life of 12 months, preferably 18 months, particularly for coffee. Accordingly, in the present context, an oxygen-tight 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 being changed , which affects the quality of a coffee drink 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 can have an OTR (Oxygen Transmission Rate) of less than 5, preferably less than 2. The OTR indicates which ones Amount of oxygen diffused through a film per unit of area and time, 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 Deckel), eine OTR (Oxygen Transmission Rate) von weniger als 5, vorzugsweise weniger als 2, haben. Dies gilt losgelöst vom verwendeten Herstellungsverfahren.However, the finished oxygen and/or aroma-tight capsule body, or the entire capsule (including the lid), can also have an OTR (Oxygen Transmission Rate) of less than 5, preferably less than 2. This applies regardless of the manufacturing process used.

Ein weiterer Aspekt der vorliegenden Erfindung betrifft ein Verfahren zum Herstellen mehrerer Kapseln wie oben beschrieben, umfassend die folgenden Schritte:

  • Bereitstellen einer Folie, insbesondere einer Kunststoff- und/oder Metallfolie;
  • Aufdrucken eines eindimensional-maschinenlesbaren Codes auf die Folie entlang einer Geraden, insbesondere in einem kontinuierlichen Verfahren;
  • Optional: Beschichten, insbesondere Kaschieren oder Lackieren, der Folie mit einer transparenten Deckschicht;
  • Ausstanzen oder ausschneiden von mehreren Deckeln aus der Folie entlang der Geraden, derart dass sich die Flächenschwerpunkte der Deckel auf der Geraden befinden;
  • Aufbringen der Deckel auf Kapselkörpern.
Another aspect of the present invention relates to a method for producing multiple capsules as described above, comprising the following steps:
  • Providing a film, in particular a plastic and/or metal film;
  • Printing a one-dimensional machine-readable code onto the film along a straight line, in particular in a continuous process;
  • Optional: Coating, especially laminating or painting, the film with a transparent top layer;
  • Punching out or cutting out several lids from the film along the straight line so that the centers of gravity of the lids are on the straight line;
  • Applying the lids to capsule bodies.

Das beschriebene Verfahren ermöglicht es, die Herstellungseffizienz von Kapseln, welche mit einem eindimensional-maschinenlesbaren Code ausgestattet sind, deutlich zu verbessern. Dies kann insbesondere dadurch erzielt werden, da der eindimensional-maschinenlesbare Code kontinuierlich auf die Folie aufgedruckt werden kann, bevor die Deckel daraus ausgestanzt oder ausgeschnitten werden. Dadurch entfällt das schwierige Ausrichten einer Druckvorrichtung für den Code auf bereits vorgefertigte Deckel.The method described makes it possible to significantly improve the manufacturing efficiency of capsules that are equipped with a one-dimensional machine-readable code. This can be achieved in particular because the one-dimensional machine-readable code can be continuously printed onto the film before the lids are punched or cut out of it. This eliminates the need for difficult alignment a printing device for the code on prefabricated lids.

Das oben beschriebene Verfahren kann ferner den folgenden Zusätzlichen Schritt umfassen:

  • Aufdrucken von zumindest einem weiteren eindimensional-maschinenlesbaren Code, welcher den ersten eindimensional-maschinenlesbaren Code kreuzt und entlang einer zweiten Geraden, insbesondere senkrecht zur ersten Geraden, verläuft, wobei die zweite Gerade bevorzugt durch den Flächenschwerpunkt des Deckels verläuft.
The method described above may further include the following additional step:
  • Printing of at least one further one-dimensional machine-readable code, which crosses the first one-dimensional machine-readable code and runs along a second straight line, in particular perpendicular to the first straight line, the second straight line preferably running through the center of gravity of the lid.

Ein weiterer Aspekt der vorliegenden Erfindung betrifft ein Getränkezubereitungssystem, umfassend eine oben beschriebene Kapsel und eine Getränkezubereitungsmaschine. Die Getränkezubereitungsmaschine weist eine Aufnahme mit zumindest einem Lesegerät auf. Die Kapsel ist in die Aufnahme einsetzbar und zumindest ein eindimensional-maschinenlesbarer Code ist mit dem zumindest einen Lesegerät lesbar.Another aspect of the present invention relates to a beverage preparation system comprising a capsule described above and a beverage preparation machine. The beverage preparation machine has a receptacle with at least one reading device. The capsule can be inserted into the receptacle and at least one one-dimensional machine-readable code can be read with the at least one reading device.

Das Lesegerät kann dabei als zumindest ein Strichcode-Scanner, insbesondere als zwei rechtwinklig zueinander geordnete Strichcode-Scanner ausgebildet sein. Dies ermöglicht es, dass ein eindimensional-maschinenlesbarer Code in jeder Orientierung der Kapsel relativ zum Lesegerät lesbar ist. Allerdings kann die Aufnahme der Getränkezubereitungsmaschine auch eine Aussparung für eine Lasche des Deckels der Kapsel aufweisen. Alternativ dazu, kann die Aufnahme auch derart ausgestaltet sein, dass die Kapsel aufgrund der Form des Kapselkörpers oder daran angebrachten Fortsätzen nur in einer Orientierung in die Aufnahme einsetzbar ist. Dies erleichtert das Auslesen eines Codes auf der Kapsel, da dies in einer vorgängig festgelegten Richtung erfolgen kann.The reading device can be designed as at least one barcode scanner, in particular as two barcode scanners arranged at right angles to one another. This enables a one-dimensional machine-readable code to be readable in any orientation of the capsule relative to the reading device. However, the holder of the beverage preparation machine can also have a recess for a tab on the lid of the capsule. Alternatively, the receptacle can also be designed in such a way that the capsule can only be inserted into the receptacle in one orientation due to the shape of the capsule body or extensions attached to it. This makes it easier to read a code on the capsule, as this can be done in a predetermined direction.

Es ist allerdings auch möglich, dass das Lesegerät als Kamerasystem ausgebildet ist. Mit einem solchen ist der eindimensional-maschinenlesbare Code in beliebiger Orientierung zum Lesegerät zuverlässig lesbar.However, it is also possible for the reading device to be designed as a camera system. With this, the one-dimensional machine-readable code can be reliably read in any orientation to the reading device.

Wie aus Figur 1 hervorgeht, kann der Deckel 2 der Kapsel 1 kreisrund ausgeführt sein. In diesem Fall entspricht der Flächenschwerpunkt S des Deckels 2 dem Mittelpunkt des durch ihn gebildeten Kreises. Zur besseren Übersichtlichkeit ist der Flächenschwerpunkt S in der vorliegenden Abbildung weiss hinterlegt. Durch den Flächenschwerpunkt S verläuft die Gerade g. Senkrecht zur Geraden g ist die Leserichtung r durch einen Pfeil symbolisiert. Der eindimensional-maschinenlesbare Code 4 ist hier als Strichcode ausgeführt, welcher sich beidseitig symmetrisch entlang der Geraden g erstreckt. In der räumlichen Darstellung gemäss Figur 2 ist die komplette Kapsel 1 mit dem eindimensional-maschinenlesbaren Code 4 auf dem Deckel 2 und dem Kapselkörper 3 ersichtlich.How out Figure 1 As can be seen, the lid 2 of the capsule 1 can be circular. In this case, the center of gravity S of the cover 2 corresponds to the center of the circle formed by it. For better clarity, the center of gravity S is highlighted in white in this figure. The straight line g runs through the center of gravity S. Perpendicular to the straight line g is the reading direction r by an arrow symbolized. The one-dimensional machine-readable code 4 is designed here as a bar code, which extends symmetrically on both sides along the straight line g. In the spatial representation according to Figure 2 the complete capsule 1 with the one-dimensional machine-readable code 4 on the lid 2 and the capsule body 3 can be seen.

Die Figuren 3 und 4 zeigen ein alternatives Ausführungsbeispiel einer erfindungsgemässen Kapsel 1 mit einer Lasche 5 am Deckel 2. Der eindimensional-maschinenlesbare Code 4 ist derart auf dem Deckel 2 angebracht, dass dieser sich auf der Lasche 5 fortsetzt.The Figures 3 and 4 show an alternative embodiment of a capsule 1 according to the invention with a tab 5 on the lid 2. The one-dimensional machine-readable code 4 is attached to the lid 2 in such a way that it continues on the tab 5.

Die Figuren 5 bis 7 zeigen weitere Ausführungsbeispiele von Deckeln 2 für erfindungsgemässe Kapseln 1. In Figur 5 ist der eindimensional-maschinenlesbare Code 4 ebenfalls als Strichcode ausgeführt, welcher jedoch neben der Geraden g verläuft. In Figur 6 ist der eindimensional-maschinenlesbare Code 4 als unregelmässig-wellenförmiger Strichcode ausgeführt. Figur 7 zeigt einen Deckel 2 mit einem eindimensional-maschinenlesbaren Code 4, der als Strichcode ausgeführt, jedoch in Form einer Tierfigur maskiert ist.The Figures 5 to 7 show further exemplary embodiments of lids 2 for capsules 1 according to the invention Figure 5 the one-dimensional machine-readable code 4 is also designed as a barcode, which, however, runs next to the straight line g. In Figure 6, the one-dimensional machine-readable code 4 is designed as an irregular, wave-shaped bar code. Figure 7 shows a lid 2 with a one-dimensional machine-readable code 4, which is designed as a barcode but is masked in the form of an animal figure.

Die Figuren 8 und 9 zeigen ein alternatives Ausführungsbeispiel einer erfindungsgemässen Kapsel 1 mit zwei gekreuzten Strichcodes 4a, 4b. Während der Strichcode 4a entlang der Geraden g verläuft, erstreckt sich der Strichcode 4b entlang der Geraden h. Die Geraden g und h schneiden sich unter einem rechten Winkel im Schwerpunkt S des Deckels 2. Im Gezeigten Ausführungsbeispiel ist in den beiden Strichcodes 4a und 4b jeweils dieselbe Information enthalten.The Figures 8 and 9 show an alternative embodiment of a capsule 1 according to the invention with two crossed bar codes 4a, 4b. While the bar code 4a runs along the line g, the bar code 4b extends along the line h. The straight lines g and h intersect at a right angle in the center of gravity S of the lid 2. In the exemplary embodiment shown, the two bar codes 4a and 4b contain the same information.

Die Figur 10 zeigt eine Zwischenstufe in einem Verfahren zum Herstellen mehrerer Kapseln 1. Im vorliegenden Beispiel wird die Folie, aus der die Deckel 2 der Kapseln 1 hergestellt werden, als Endlosstreifen 6 bereitgestellt, welcher kontinuierlich entlang der Geraden g mit dem eindimensional-maschinenlesbaren Code 4 bedruckt wird. Die spätere Kontur der Deckel ist durch die strichlierten Kreise 7 angedeutet.The Figure 10 shows an intermediate stage in a process for producing several capsules 1. In the present example, the film from which the lids 2 of the capsules 1 are produced is provided as an endless strip 6, which is printed continuously along the straight line g with the one-dimensional machine-readable code 4 . The later contour of the lid is indicated by the dashed circles 7.

Die Figur 11 zeigt die an die oben beschriebene Zwischenstufe anschliessenden Verfahrensschritte zur Herstellung der Kapseln 1. Die Kreisrunden Deckel 2 werden entlang der Geraden g aus dem Endlosstreifen 6 ausgestanzt oder ausgeschnitten. Hierzu wird eine Stanze 8, 8' bzw. ein Messer verwendet. Die Deckel 2 werden darauf auf Kapselkörper 3 aufgebracht, um Kapseln 1 zu erhalten.The Figure 11 shows the process steps for producing the capsules 1 following the intermediate stage described above. The circular lids 2 are punched or cut out of the endless strip 6 along the straight line g. For this purpose, a punch 8, 8' or a knife is used. The lids 2 are then applied to capsule bodies 3 to obtain capsules 1.

Die Figuren 12 und 13 zeigen das Einlegen einer erfindungsgemässen Kapsel 1 in eine dazu geeignete Getränkezubereitungsmaschine. Die Maschine weist eine Aufnahme 9 auf, die sich aus den beiden Hälften 9' und 9" zusammensetzt. Die obere Hälfte 9' ist mit einem Lesegerät 10 für den für den eindimensional-maschinenlesbaren Code 4 der Kapsel 1 ausgestattet. Die untere Hälfte 9" weist einen konkaven Bereich auf, dessen Form im Wesentlichen der Aussenkontur des Kapselkörpers 3 entspricht. Zudem verfügt die untere Hälfte 9" der Aufnahme eine Aussparung 11 für die Lasche 5 der Kapsel 1. Im gezeigten Ausführungsbeispiel sind an der oberen und unteren Hälfte 9', 9" der Aufnahme jeweils Penetrationselemente 12, 13 zum Durchleiten einer Flüssigkeit durch die Kapsel 1 angebracht.The Figures 12 and 13 show the insertion of a capsule 1 according to the invention into a suitable beverage preparation machine. The machine has a receptacle 9, which is composed of the two halves 9' and 9". The upper half 9' is equipped with a reader 10 for the one-dimensional machine-readable code 4 of the capsule 1. The lower half 9" has a concave area, the shape of which essentially corresponds to the outer contour of the capsule body 3. In addition, the lower half 9" of the receptacle has a recess 11 for the tab 5 of the capsule 1. In the exemplary embodiment shown, there are penetration elements 12, 13 on the upper and lower half 9 ', 9" of the receptacle for passing a liquid through the capsule 1 appropriate.
