A capsule includes a cup-like capsule body with a circumferential side wall, a transverse base wall at a first end of the side wall, and a radially outwardly protruding flange encircling the side wall at its second end, and a multi-layered sealing ring lying against the flange while encircling the side wall. The sealing ring includes a compressible layer of fibrous and/or cellulose and/or paper material and an outer shielding layer of a liquid-impermeable material, where the shielding layer is provided on an outwardly directed external surface of the sealing ring and where the shielding layer is configured for shielding the inner compressible layer of fibrous and/or cellulose and/or paper material against pressurized liquid during beverage production.
