1. A capsule containing a substance for the preparation of a potable beverage by extracting and/or dissolving the substance by a fluid supplied under pressure into the capsule, wherein the capsule comprises an aluminum capsule body having a central capsule body axis, said aluminum capsule body being provided with a bottom, a side wall and an outwardly extending flange, the capsule further comprising an aluminum cover attached to the outwardly extending flange, the cover hermetically closing the capsule, wherein the capsule further comprises a sealing member at the outwardly extending flange for providing a fluid sealing contact with an enclosing member of a beverage preparation device if the capsule is positioned in the enclosing member of the beverage preparation device and the enclosing member is closed by means of a closing member of the beverage preparation device such that the outwardly extending flange of the capsule and at least a portion of the sealing member of the capsule are sealingly engaged between the enclosing member and the closing member of the beverage preparation device, wherein the enclosing member of the beverage preparation device comprises an annular element having a central annular element axis and a free contact end, wherein, the sealing member is integral with the outwardly extending flange and comprises a first projection extending from the outwardly extending flange, the first projection comprising a projection top, and wherein the first projection is configured such that its projection top exerts a radial force on the free contact end of the annular element if the capsule is positioned in the enclosing member of the beverage preparation device and the enclosing member is closed by means of the closing member of the beverage preparation device, wherein the sealing member comprises a second projection extending from the outwardly extending flange and a plateau between projections, wherein a distance between the first and second projections is such that the free contact end of the annular element is enclosed between the first and second projections if the capsule is positioned in the enclosing member and the enclosing member is closed by means of the closing member and wherein the first projection extends further from a base portion of the outwardly extending flange, to which base portion the cover is attached, than the second projection.
