Abstract
A brewing means (1) for a coffee machine with a brewing chamber (3) is described, which is disposed in a housing (2) provided with an opening (9) on a front side. The opening (9) can be closed by means of a closing element (10) sealed against the opening. A hot water line (11) is furthermore provided, which supplies hot brewing water to the brewing chamber (3) under pressure and supports at the same time the sealing of the opening (9). In order to design such a brewing means (1) in such fashion that the service life of the seal (21) can be increased, it is suggested that the seal (21) comprises a flexible membrane disposed between a sealing chamber (22) connected to the hot water line (11) and a sealing seat (19), which can be arched and pressed against the sealing seat by means of the pressure.
