Abstract

A capsule or cartridge () including a cup-shaped body () with a bottom wall (), a lateral wall () and a flange-like top formation () which is essentially planar and extends transversely towards the outside, and a cover () fixed to the flange-like formation () of the body (), such as to define a chamber () containing the material for the preparation of the beverage, in particular ground roasted coffee. The lateral wall () of the body () has a plurality of projections () and recesses () which as a whole define at least an identification of the capsule (). The projections () and recesses () are aligned in an essentially rectilinear direction, belonging to a plane essentially parallel to the flange-like formation () of the body () of the capsule ().
