A beverage filter cartridge includes an impermeable yieldably pierceable base having a predetermined shape and an access opening at one end. A self-supporting wettable filter element is disposed in the base and is permanently sealed to an interior surface of the base. The filter element subdivides the base into first and second chambers, a first chamber for storing an extract of the beverage to be made, and a second empty chamber for accessing the beverage after the beverage outflow from the filter has been made by combining a liquid with the extract. An impermeable, yieldably pierceable, imperforate cover is sealingly engaged with the top of the base to form an impermeable cartridge.

Beverage filter cartridge

A beverage filter cartridge includes an impermeable pierceable base having a predetermined shape and an opening at one end; a self-supporting wettable filter element disposed in the base sealingly engages with the opening in the base and has a form different and smaller than the predetermined shape of the base so that the filter element diverges from the base and divides the base into two sealed chambers, a first chamber for storing an extract of the beverage to be made, and a second empty chamber for accessing the beverage after the beverage outflow from the filter has been made by combining a liquid with the extract; and an impermeable pierceable cover sealingly engaged with the opening in the base to form an impermeable cartridge.
