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.
Capsule (1) par exemple pour préparation de café, comprenant un corps (2) de préférence à symétrie de rotation et pourvu d'une paroi latérale (3), et un fond (4) formé d'un seul tenant avec ladite paroi latérale. La capsule est fermée de manière étanche par un opercule (5) de manière à former une chambre destinée à recevoir la substance (7) contenue dans la capsule. Le fond (4) et l'opercule (5) peuvent être transpercés par des moyens appropriés de telle façon qu'un liquide puisse traverser la capsule. Le fond (4) est doté d'une goulotte annulaire (8) dont la partie paroi interne (9) forme une zone de renforcement. Le fond (11) de la goulotte forme une zone de transpercement qui peut être transpercée plus efficacement grâce à la zone de renforcement et sans déformation du fond de capsule en entier.
