  • Holder for inclining a coffee cartridge
    Patent number: 4995978
    Abstract: A filter device has a coffee-cartridge holder (11) constructed to receive a coffee cartridge (1) having two facing walls (2, 3) made of a filter material, one of said walls (2) being adapted to receive water (8) for making coffee. In order to prevent the foam formed during the extraction process from excessively influencing the extraction time, it is proposed to provide the coffee-cartridge holder (11) or the coffee cartridge (1) or both with means which ensure that, when the holder is in the operating position and containing the coffee cartridge, the wall (2) of a filter material to which water is supplied is inclined at an angle between 15 and 90 to the horizontal.
