The body is of conical construction such that the body can be ejected from a brewing machine. At the capsule base there is a protruding rim. Said rim is needed for the brewing machine to be able to approach the capsule and form a seal therewith, in order to subsequently be able to inject hot water at pressure into the capsule. The aim of the invention is to provide an improvement of or an alternative to the prior art.
