Definitions

  • the invention relates to a portion capsule for producing a beverage, comprising a base element which comprises a cavity in which a beverage raw material is provided and which is sealed by a membrane which is secured to the base element. Said base element is provided with an identifier, which enables the respective portion capsule to be individualised.
  • the invention further relates to a method for producing a portion capsule and to the use of the portion capsule for producing a beverage.
  • Such portion capsules are well known and are offered on the market in a variety of embodiments. They are used to produce coffee, espresso, cappuccino, tea, milk or cocoa beverages as well as other beverages or foods such as soups. To be able to be produced in a machine these capsules must all have the same outer shape, the difference being in the respective manufacturing method. For example, the amount of water and/or the temperature used for the production of a particular beverage can differ. Furthermore, the water of the portion capsule can be conducted continuously or intermittently through the portion capsule. The vending machines used to produce the particular beverage or food must be cleaned at regular intervals.
  • cleaning capsules are available, the outer dimensions of which are identical to the outer dimensions of the portion capsules, and through which water can also stream after it has [sic] been introduced into the machine, which releases the cleaning substance from the capsules and, with the solution, cleans the machine's infusion chamber and downstream pipes. That a user, for example a child or a visually impaired adult, uses the cleaning capsule to produce a beverage and consumes, must be avoided at all costs.
  • the object of the present invention is to provide a portion capsule which is only suitable for a quite specific beverage vending machine, which can be produced at low cost and/or which can avoid the disadvantages identified in connection with the prior art.
  • a portion capsule for producing a beverage comprising a capsule body with a capsule base and a cover.
  • a cavity, which is formed between the capsule base and the cover comprises a beverage substrate and said capsule comprises a machine-detectable identifier, which enables the respective portion capsule to be individualised.
  • the identifier is provided in a mono-layer or multi-layer plastic film, from which the portion capsule is, at least partially, produced.
  • the invention relates to a portion capsule for producing a beverage or food, which comprises a cavity in which a beverage raw material is provided.
  • a portion capsule is made, for example, out of plastic, a natural material and/or a biodegradable material and comprises a base element, in particular a shaped, preferably deep-drawn base element or a base element produced by spikes, which is preferably conical or cylindrical in shape, and comprises a base.
  • the beverage raw material which is, for example, extracted and/or released from a liquid, in particular water, is poured into the cavity of the portion capsule.
  • the base element is sealed, in particular with a membrane.
  • the membrane is preferably provided opposite the base of the base element.
  • the membrane can be made from the same material as the base element or from a different material and is preferably attached to the base element through sealing or gluing.
  • the membrane can be designed to be impervious to gas and/or liquids or permeable to gas and/or liquids.
  • one or more built-in elements such as a filter, a liquid distributor, a fleece, a felt material, a protective foil, and/or such like, can be provided.
  • a felt material and a fleece are provided, they are preferably bonded to one another.
  • the felt material and/or the fleece can be multi-layered, in which case the layers can differ as to the kind of material used and/or the processing of the material used.
  • the membrane and/or the base can be provided with several recesses (holes).
  • this portion capsule comprises an identifier, which enables the respective portion capsule to be individualised.
  • ‘to be individualised’ means that the particular portion capsule can be assigned to the appropriate group for the production of a beverage or food or for the cleaning of the vending machine.
  • the identifier it not necessary for the identifier to disclose which particular portion capsule is being referred to, i.e. for it to contain a serial number or batch number or such like, just to allow the assignment of the particular portion capsule to a group of portion capsules, for example beverage and/or food portion capsule, or cleaning capsule.
  • the identifier also makes it possible to distinguish between the individual beverages and/or type of food, for example, that a capsule is being referred to with which tea, coffee, a milky drink or such like, or a soup, can be produced.
  • a sensor/detector fitted to a vending machine, for example a coffee vending machine, detects this identifier and compares it preferably with a stored identifier.
  • the vending machine in particular its pressure pump, which provides the water, can only be put into operation if the detected identifier matches up with the reference identifier of a beverage/food portion capsule. Otherwise, the vending machine can not be put into operation, because there is a risk that the capsule identified might be a cleaning capsule in which there is a cleaning agent, for example.
  • the vending machine can, for example, only be put into operation if a specific key combination is previously pressed on the control panel of the vending machine, with which the user verifies that he or she is aware that this capsule is a cleaning capsule. This will ensure that a cleaning capsule is not accidentally used for the production of a beverage.
  • the identifier can be used to ensure that the coffee vending machine drives a specific program, i.e. heats the water to a specified temperature, for example, provides the water at a specified pressure, and/or conveys a specified amount of water through the portion capsule.
  • the identifier can be used to sort the materials from which the portion capsule is produced during a subsequent disposal and/or recycling process.
