CAPSULE, A SYSTEM FOR PREPARING A POTABLE BEVERAGE FROM SUCH A CAPSULE AND USE OF SUCH A CAPSULE IN A BEVERAGE PREPARATION DEVICE

摘要

A capsule containing a substance for the preparation of a potable beverage. The capsule comprises an aluminum capsule body having a side wall and an outwardly extending flange. The capsule is hermetically closed by an aluminum cover attached to the outwardly extending flange. 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. The capsule further comprises an elastic support structure, which is attached to an outer cover surface of said cover. In a condition, in which the capsule is freely resting with said elastic support structure on a fully straight reference surface, the elastic support structure provides a spacing between the outwardly extending flange and said reference surface, said spacing being constant all around in the circumferential capsule direction.
