Abstract

The present invention concerns a container (1) containing coffee ingredient, comprising a chamber delimited by an injection wall (3) able to be punctured or otherwise opened for circulating water under pressure and by a coffee delivery wall (4), the entire chamber being filled with said coffee. At least a portion of said injection wall (3) has the shape of a half torus, or a half toroidal polyhedron, so as to define a ring-shaped chamber portion (2).
