Abstract:
1. A method for producing a beverage from an ingredient-containing capsule, which comprises: enclosing a sealed capsule into a capsule enclosure space of a beverage production device by a relative displacement of at least two enclosing members which define the capsule enclosure space, wherein the capsule comprises first and second wall members that are sealed at their peripheries to form a flange-like rim and that enclose beverage forming ingredients therein, with the first wall member including an inlet face and the second wall member including an outlet face, and with the enclosing members of the device including a first enclosing member arranged for opening the inlet face of the capsule and injecting a fluid under pressure therein, and a second enclosing member arranged for opening the outlet face of the capsule, opening the inlet face of the capsule with the first enclosing member which injects a fluid under pressure into the capsule in order to eventually open the outlet face of the capsule, the opening of the outlet face of the capsule being assisted by the fluid pressure inside the capsule, wherein the capsule has sealing material on part of the outer surface of the first wall member or extending from a portion of the flange-like rim adjacent the first wall member to form part of the capsule, which sealing material is exposed to the fluid pressure in the capsule enclosure space, and after enclosing the capsule, having the fluid pressure reigning in the capsule enclosure space at least partially act on the sealing material, such that in turn the sealing material is pressed against the first enclosing member thus constituting a flow resistance which prevents the fluid from bypassing the ingredients in the capsule and which is sufficient to guarantee a pressure build-up inside the capsule sufficient for the pressure-assisted opening of the outlet face of the capsule.
