Definitions

  • the present invention relates to a portion capsule for production of a beverage with a base element, having a cavity, in which a beverage raw material is provided and which is sealed by a membrane, which is fastened to the base element, wherein it has an identification, which enables the respective portion capsule to be individualised.
  • the present invention further relates to a method for manufacture of a portion capsule and the use of the portion capsule for producing a beverage.
  • Such portion capsules are well known and are offered on the market in numerous versions and are used to produce coffee, espresso, cappuccino, tea, milk or chocolate beverages and also other beverages, or foods such as soups. To enable them to be produced in a machine, these capsules must all have the same external shape, for which the respective manufacturing methods differ. For example, the amount of water and or the temperature used for producing the respective beverage can differ. Furthermore, the water for the portion capsule can be passed continuously or intermittently through the portion capsule.
  • the machines that are used for producing the respective beverage or food must be cleaned at regular intervals, for which cleaning capsules are available whose external dimensions are identical to the dimensions of the portion capsules and through which water also flows after it has been introduced into the machine to dissolve the cleaning substance from the capsules and cleaning the brewing chamber of the machine and the downstream piping. In doing so, it is essential to avoid a user, for example a child or a disabled adult, using the cleaning capsule to produce a beverage and then consume it.
  • a portion capsule for production of a beverage with a base element, having a cavity in which a beverage raw material is provided, and which is sealed by a membrane, which is fastened to the base element, wherein it has an identification, which enables the respective portion capsule to be individualised, wherein the identification is provided on a film which is attached to the membrane and/or the base element.

It is not necessary for the identification to disclose which portion capsule is especially involved, i.e. contains a serial number or batch number or the like, but only allows the classification of the respective portion capsule to a group of portion capsules, for example beverage/food portion or cleaning capsule. Preferably the identification additionally allows the differentiation between the individual beverages and/or type of food, for example that it is a capsule with which tea, coffee or a milk drink or the like or a soup can be produced.

  • a further advantage of the portion capsule according to the invention is that, because of the arrangement of grooves in the wall area of base element, it performs better when the extraction liquid flows through it in the brewing chamber because, due to the arrangement of grooves, in particular their course between the membrane and the bottom area over at least part of the height of the wall area, it is possible to increase the quality and reliability of the extraction process significantly.
  • the thickness of the material of the base element is thus substantially more cost-effective and environmentally friendly.
  • the plurality of the grooves due to the plurality of the grooves, adherence of the wall area to the brewing chamber wall in the brewing chamber is reduced or avoided, favouring the ejection or removal of a portion capsule from the brewing chamber.
  • a further advantage of the plurality of grooves is that the flow of extraction liquid within the cavity along the bottom area can be optimised by the groove structure in the wall area so that, by design of the group structure, a better or stronger turbulence of the extraction liquid in the cavity or a more uniform (laminar) flow of the extraction liquid results or can be realised by simple means.
  • a stronger turbulence of the extraction liquid in the cavity in comparison with the prior art, has the advantage that no unwanted and random main liquid streams are formed through the bed of beverage raw material but instead flow through the whole volume of the beverage raw material.

  • this portion capsule now has an identification, with which it can be established whether the respective portion capsule is suitable or producing a beverage or food. If this is not the case, significant health problems can result. For example, by using a cleaning capsule, a watery solution that is unpalatable for the user can be produced. This must be avoided.
  • the identification 7 is provided on a film 6 , in particular a plastic foil, which, after the portion capsule has been formed, is attached to the base element 2 of the portion capsule, as the arrow 5 shows.
  • the identification 7 has at least one, preferably two stripes, which differ in their optical characteristics from the material of the film and/or from the material of the base element of the portion capsule.
  • the identification has a different colour or other light reflection characteristics from at least one of the two materials and/or the area 8 between two identifications 7 .
  • the film 6 extends around the complete circumference of the base element.
  • each identification 7 extends around the complete outer circumference of the film/film ring.
  • it is preferable that neither the film nor the identification extends over the whole length of the base element of the portion capsule.
  • identification shown in FIG. 2 can also be made by application of ink, by one or a plurality of nozzles located in the deep-drawing die on the circumference of the base element of the portion capsule and/or by rotating the portion capsule during application.
  • the film is made available as tubing, which can be cut to the required length ( FIG. 3 ).
  • the identification is preferably applied to the film or the film is made from two materials, wherein one shows the identification, for example another colour.
  • the ends 6 . 1 , 6 . 2 of the film are joined together after manufacture. This can be carried out before the film is attached to the base element, during attachment or after attachment.
  • the ends 6 . 1 , 6 . 2 can also be arranged edge-to-edge or at a distance from one another.
  • FIG. 5 shows another embodiment of the portion capsule according to the invention in a side view and a bottom view.
  • the identification 7 is provided on the underside 2 . 3 . 1 of the rim/flange of the portion capsule, for example an application, in particular an ink application.
  • the underside is the side facing the bottom or the side of the rim remote from the membrane.
  • the ink application extends in a circular ring.
  • the identification 7 can also be an RFID, which is preferably provided as a circular segment. This circular segment is preferably cut or stamped out of a plastic foil.
  • the RFID can be laminated and/or printed on this plastic foil.
  • the bond between the plastic foil and the RFID is preferably made by sealing or adhesive bonding, particularly preferably during the deep-drawing of the base element 2 .
  • the RFID can also be printed on.
