Claim:
1. A method for producing a beverage using a capsule in a centrifugal beverage producing device, the method comprising: placing the capsule in the centrifugal beverage production device for preparing the beverage from a substance contained in the capsule by introducing liquid in the capsule and passing the liquid through the substance using centrifugal forces, the capsule comprising a body comprising a bottom end and an open end, an upper wall for covering the body at the open end, an enclosure between the body and the upper wall containing a predetermined amount of the substance, and a flange-like rim extending outwardly from the body, wherein the flange-like rim comprises an annular force ring designed for being engaged by an enclosing member of the centrifugal beverage production device, wherein the annular force ring comprises at least one curved, folded part formed of at least a first folded ply and a second folded ply, the first folded ply forms (i) an inner section tilted at an angle with respect to a central axis of rotation of the capsule, (ii) a bent intermediate section extending from the inner section, and (iii) an outer section extending from the bent intermediate section to a lower circumferential edge in a direction essentially parallel to the central axis of rotation; and the second folded ply forms a section of the annular force ring bent inwardly from the lower circumferential edge toward the body of the capsule, and wherein the curved, folded part of the annular force ring extends, in a direction away from the body of the capsule and beyond a plane in which a portion of the flange-like rim is sealed on the upper wall, by a distance of extension from the plane; and centrifuging the capsule wherein in the centrifugal beverage producing device the annular force ring is engaged by the enclosing member of the centrifugal beverage production device, the annular force ring forming part of a valve for selectively blocking and/or restricting a flow of the liquid coming out of the capsule.
