The filter pan and the filter cartridge are made of materials having different coefficients of expansion and the portions coacting for sealing purposes are dimensioned in such a manner that, upon insertion of the cartridge, it rests without clamping or loosely in the pan and the water seal is obtained by means of the capillary forces and/or the clamping effect occurring when the hot water is being infused.
