摘要： The invention relates to a capsule (10) designed for preparing a beverage upon injection of liquid into the capsule by means of a beverage preparation machine. The capsule (10) comprises a cup-shaped base body (1) for holding beverage preparation ingredients and a flange-like rim (2) with a sealing member (3) comprising an inner and an outer series (4,5) of arc-shaped protrusions (4a,5a), wherein the base-body (1), the flange-like rim (2) and the sealing member (3) are made integrally from metallic material such as aluminum, in which the inner and outer series (4,5) of the sealing member (3) are concentrically arranged on a surface (2a) of the flange-like rim (2) such as to form an annular space (6) there-between for receiving a sealing surface (21a) of a capsule engagement member (21) of the beverage preparation machine (20). The respective arc-shaped protrusions (4a,5a) of the inner and outer series (4,5) are continuous protrusions with circumferentially extending gaps (4b,5b) formed there- between, wherein the respective arc-shaped protrusions (4a,5a) of the inner and outer series (4,5) are arranged such as to circumferentially overlap outside the circumferentially extending gaps (4b, 5b) of the inner and outer series (4, 5) in side view of the capsule, and wherein the arc-shaped protrusions (4a,5a) of the inner and outer series (4,5) are locally connected together by at least one bridging element (8) positioned proximate to each circumferentially extending gaps (4b, 5b) of the inner and outer series (4, 5).
