摘要

A system for preparing a drinkable beverage, comprising: a capsule, a first beverage preparation device and a second beverage preparation device each arranged to receive the capsules. The capsule includes a sealing member at the outwardly extending flange to provide a fluid sealing contact with the first enclosure member when the capsule is used in the first beverage preparation device. A first sealing interface exists between the capsule and the first enclosure member for providing a fluid sealing contact when the capsule is positioned within the first enclosure member and the first enclosure member is closed by the first enclosure member, wherein the capsule is in the second enclosure A second sealing interface exists between the capsule and the second enclosure member positioned within the member and for providing a fluid sealing contact when the second enclosure member is closed by the second closure member, the second sealing interface being with the first sealing interface and the second enclosure member. different
