Portion capsule comprising a plastic film provided with a machine-detectable identification

Abstract

The invention relates to a portion capsule ( 1 ) for producing a beverage, comprising a capsule body ( 2 ) with a capsule base ( 2.2 ) and a cover ( 3 ). A cavity ( 4 ), which is formed between the capsule base ( 2.2 ) and the cover ( 3 ) comprises a beverage substrate and said capsule comprises a machine-detectable identifier ( 5 ), which enables the respective portion capsule to be individualised. The invention also relates to the use of the portion capsule for producing a beverage.

1 . Portion capsule ( 1 ) for producing a beverage, comprising a capsule body ( 2 ) made from plastic film ( 6 ) with a capsule base ( 2 . 1 ) and a cover ( 3 ) made from plastic film, wherein, between the capsule base ( 2 . 1 ) and the cover ( 3 ), a cavity ( 4 ) is formed in which a beverage substrate is provided, and which comprises a machine-detectable identifier ( 5 ), which enables the respective portion capsule to be individualised, wherein the identifier is provided in a mono-layer or multi-layer plastic film ( 6 ), from which the portion capsule is, at least partially, produced, wherein at least one layer (a) of the plastic film ( 6 ) comprises a specified value for the surface resistance and/or contact resistance as identifier ( 5 ), characterised in that the layer (a) is constructed from at least two thermoplastic polymers with a different value for electrical resistance. 
     
     
         2 . Use of a portion capsule ( 1 ) according to  claim 1  for the production of a beverage.
