Portion Capsule Having an Identifier

Abstract

The present invention relates to a portion capsule for producing a beverage, comprising a basic element having a cavity in which a raw beverage material is provided and being closed by a membrane fastened to the basic element.

1 . A portion capsule for producing a beverage, comprising a basic element having a wall region and a bottom area spanning a cavity in which a raw beverage material is provided, and having a periphery region provided on the basic element and the cavity being preferably closed by a membrane which is fastened to the periphery region of the basic element, the portion capsule having an identifier which makes it possible to individualize the respective portion capsule, wherein the identifier is a code, in particular a barcode, which is provided on a side of the periphery region of the basic element facing away from the membrane, and wherein indentations and/or protrusions are provided, which extend at least in sections between the periphery region and the bottom area in the wall region, wherein the indentations and/or protrusions are grooves/notches, wherein their longitudinal extent is provided at an angle >0 and <180° relative to a central axis/rotation axis. 
     
     
         2 . The portion capsule according to  claim 1 , wherein a cross-section of the grooves/notches changes with their longitudinal extension. 
     
     
         3 . The portion capsule according to  claim 1 , wherein the grooves/notches are provided at least partially crossing each other. 
     
     
         4 . A portion capsule for producing a beverage, comprising a basic element having a wall region and a bottom area spanning a cavity in which a raw beverage material is provided, and having a periphery region provided on the basic element and the cavity being preferably closed by a membrane which is fastened to the periphery region of the basic element, the portion capsule having an identifier which makes it possible to individualize the respective portion capsule, wherein the identifier is a code, in particular a barcode, which is provided on a side of the periphery region of the basic element facing away from the membrane, and wherein indentations and/or protrusions are provided, which extend at least in sections between the periphery region and the bottom area in the wall region, wherein the indentations and/or protrusions are provided as a golf ball structure. 
     
     
         5 . The portion capsule according to  claim 4 , wherein the indentations have a circular, oval or polygonal cross-section. 
     
     
         6 . A portion capsule for producing a beverage, comprising a basic element having a wall region and a bottom area spanning a cavity in which a raw beverage material is provided, and having a periphery region provided on the basic element and the cavity being preferably closed by a membrane which is fastened to the periphery region of the basic element, the portion capsule having an identifier which makes it possible to individualize the respective portion capsule, wherein the identifier is a code, in particular a barcode, which is provided on a side of the periphery region of the basic element facing away from the membrane, and wherein indentations and/or protrusions are provided, which extend at least in sections between the periphery region and the bottom area in the wall region, wherein the indentations and/or protrusions are grooves/notches and/or the indentations and/or protrusions are provided as golf ball structure, wherein the indentations and/or protrusions are applied. 
     
     
         7 . Use of the portion capsule according to  claim 1  for preparing a hot beverage.
