ABSTRACT:
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.
