An apparatus for making one or more consumption units of a hot beverage, such as coffee, comprising a combination of a filter pan and a disposable filter cartridge with filters of fibrous web material, fitting therein, said pan and cartridge being provided with coacting walls ensuring a water seal between the said portions when the cartridge is being introduced into the pan and water is being infused. 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. |
