System for preparing a beverage from a capsule using a fluid supplied under pressure into the capsule for use in such a system

System for preparing a potable beverage, the system comprising:

• a multi-seal capsule containing a substance for the preparation of a potable beverage by extracting and/or dissolving the substance by means of a fluid supplied under pressure into the multi-seal capsule, wherein the multi-seal capsule comprises an aluminum capsule body having a central capsule body axis, the aluminum capsule body being provided with a bottom, a side wall and an outwardly extending flange, and further comprises an aluminum cover attached to the outwardly extending flange, the cover hermetically closing the multi-seal capsule,
• a first beverage preparation device including a first enclosing member for receiving the multi-seal capsule, wherein the first enclosing member comprises first fluid injection means for supplying fluid under pressure into the multi-seal capsule received in the first enclosing member, wherein the first beverage preparation device comprises a first closing member for closing the first enclosing member, wherein the first enclosing member includes a first annular element having a first central annular element axis and a first free contact end, said first free contact end of the first annular element optionally being provided with a plurality of radially extending first open grooves,
• a second beverage preparation device including a second enclosing member for receiving the multi-seal capsule, wherein the second enclosing member comprises second fluid injection means for supplying fluid under pressure into the multi-seal capsule received in the second enclosing member, wherein the second beverage preparation device comprises a second closing member for closing the second enclosing member, wherein the second enclosing member includes a second annular element having a central second annular element axis and a second free contact end, said second free contact end of the second annular element optionally being provided with a plurality of second radially extending open grooves,
• wherein the multi-seal capsule includes a sealing member at the outwardly extending flange for providing a fluid sealing contact with the first enclosing member if the capsule is positioned in the first enclosing member and the first enclosing member is closed by means of the first closing member, such that the outwardly extending flange of the multi-seal capsule and at least a portion of the sealing member of the multi-seal capsule are sealingly engaged between the first enclosing member and the first closing member,
• wherein the sealing member of the multi-seal capsule is integral with the outwardly extending flange and comprises at least one projection projecting from the outwardly extending flange, said at least one projection comprising a projection top, and wherein the at least one projection is configured such that its projection top exerts a radial force on the first free contact end of the first annular element if the capsule is positioned in the first enclosing member and the first enclosing member is closed by means of the first closing member of the first beverage preparation device,
• wherein there is a first sealing interface between the multi-seal capsule and the first enclosing member for providing a fluid sealing contact if the multi-seal capsule is positioned in the first enclosing member and the first enclosing member is closed by means of the first closing member,
• wherein there is a second sealing interface, different than the first sealing interface, between the multi-seal capsule and the second enclosing member for providing a fluid sealing contact if the multi-seal capsule is positioned in the second enclosing member and the second enclosing member is closed by means of the second closing member.

A multi-seal capsule containing a substance for the preparation of a potable beverage by extracting and/or dissolving the substance by means of a fluid supplied under pressure into the multi-seal capsule, wherein the multi-seal capsule comprises an aluminum capsule body having a central capsule body axis, the aluminum capsule body being provided with a bottom, a side wall and an outwardly extending flange, and further comprises an aluminum cover attached to the outwardly extending flange, the cover hermetically closing the multi-seal capsule,

• wherein the multi-seal capsule is arranged for being receivable in:
• a first beverage preparation device including a first enclosing member for receiving the multi-seal capsule, wherein the first enclosing member comprises first fluid injection means for supplying fluid under pressure into the multi-seal capsule received in the first enclosing member, wherein the first beverage preparation device comprises a first closing member for closing the first enclosing member, wherein the first enclosing member includes a first annular element having a first central annular element axis and a first free contact end, said first free contact end of the first annular element optionally being provided with a plurality of radially extending first open grooves, and
• a second beverage preparation device including a second enclosing member for receiving the multi-seal capsule, wherein the second enclosing member comprises second fluid injection means for supplying fluid under pressure into the multi-seal capsule received in the second enclosing member, wherein the second beverage preparation device comprises a second closing member for closing the second enclosing member, wherein the second enclosing member includes a second annular element having a central second annular element axis and a second free contact end, said second free contact end of the second annular element optionally being provided with a plurality of second radially extending open grooves,
• wherein the multi-seal capsule includes a sealing member at the outwardly extending flange for providing a fluid sealing contact with the first enclosing member if the capsule is positioned in the first enclosing member and the first enclosing member is closed by means of the first closing member, such that the outwardly extending flange of the multi-seal capsule and at least a portion of the sealing member of the multi-seal capsule are sealingly engaged between the first enclosing member and the first closing member,
• wherein the sealing member of the multi-seal capsule is integral with the outwardly extending flange and comprises at least one projection projecting from the outwardly extending flange, said at least one projection comprising a projection top, and wherein the at least one projection is configured such that its projection top exerts a radial force on the first free contact end of the first annular element if the capsule is positioned in the first enclosing member and the first enclosing member is closed by means of the first closing member of the first beverage preparation device,
• wherein there is a first sealing interface between the multi-seal capsule and the first enclosing member for providing a fluid sealing contact if the multi-seal capsule is positioned in the first enclosing member and the first enclosing member is closed by means of the first closing member,
• wherein there is a second sealing interface, different than the first sealing interface, between the multi-seal capsule and the second enclosing member for providing a fluid sealing contact if the multi-seal capsule is positioned in the second enclosing member and the second enclosing member is closed by means of the second closing member.
