摘要

The cartridge (1) according to the invention comprises an envelope (2) having a first and a second end wall (4, 5) connected together by an annular lateral wall (6) and defining an inner chamber (7) containing a quantity or dose of a substance (S) for preparation of the beverage. The envelope (2) has at least one first and at least one second permeable wall (6a, 5) acting as an inlet for the introduction of a flow of water into the chamber (7) and as an outlet from it respectively for outflow of the beverage from chamber (7). Between the first and the second permeable walls (6a, 5) the envelope (2) has an outwardly projecting annular formation (3g). A portion of the permeable inlet wall (6a) for the introduction of water into the chamber (7) is made in the annular lateral wall (6) of the envelope (2). The annular formation (3g) extends from the second end wall (5) in a direction substantially opposite to the first end wall (4).
