A capsule (1), for example for brewing coffee consists of a preferably rotationally symmetrical capsule body (2) comprising a side wall (3) and a base (4) that is formed as one piece with said wall. The capsule is sealed by a lid (5), creating an impervious chamber for holding the substance (7) contained in the capsule. The base (4) and lid (5) can be pierced by suitable means to allow a liquid to be conducted through the capsule. The base (4) is provided with an annular channel (8), the inner wall section (9) of which forms a reinforcement zone. The base (11) of the channel forms a piercing zone, which can be pierced more effectively as a result of said reinforcement zone, without the deformation of the entire capsule base. |
