Machine-readable identifier on a portion package, which contains ground coffee, for espresso machines

摘要

A machine readable identification on a single-serving unit containing coffee powder for espresso machines, designed so that it can be read easily and accurately, is structured in a rotation-symmetrical manner and is applied to an essentially level surface of the single-serving unit, whereby the single-serving unit preferably consists of a single-serving capsule ( 1 ) having an essentially circular base ( 2 ) whereupon the identification is applied in a coaxial manner.
