<p>The device has a capsule holder receiving and supporting a capsule and detachable from a pressurized fluid supply unit. An injection unit (5) is provided through an injection support i.e. disc, of the supply unit, and movable in engagement to the capsule. An elastic ring (16) is associated with the injection unit for carrying out local and direct sealing between the injection unit and an injection wall of the capsule. An activation system applies a locking effort of the supply unit against a support side (40) of the capsule holder and an edge (34) of the capsule. An independent claim is also included for a method for reducing liquid resurgence or gas-liquid mixture through an injection point of a capsule.</p> |
