    摘要: The invention relates to a filter cartridge (1) which comprises a firmly fixed lid (10) and has a long service life. Said lid (10) is embodied in such a way that the bottom (11) of the lid extends towards the peripheral wall (3) of the cartridge container to join the lateral wall (16) of the lid, by means of an inwardly curved edge section (14), the curved edge section (14) and the lateral wall (16) in the form of a strip joining in the forming region to form an inwardly tapered common wall section (15). In this way, the region fixing the lateral wall (16) to the peripheral wall (3) is subjected only to a tensile load, minimizing the risk of shear fracture, and the inner pressure in the region of the common wall section (15) presses the wall section against the peripheral wall (3), thus exerting an additional sealing force.
