Abstract

A filtering device for the preparation of coffee, with a pot-shaped vessel, at the bottom of which a sieve sheet is attached, and with a water distribution plate, which is adapted to be supported by the upper edge of the vessel. The diameter of the water distribution plate is smaller than the inner diameter of the vessel, and a plurality of feet protrude from the edge of the water distribution plate nearly perpendicularly to the surface of the same. The free ends of the feet each form a shoulder, which serve to rest on the upper edge of the vessel such that the water distribution plate lies within the interior of the vessel and leaves a circumferential clearance to the same. Hot water which is poured onto the water distribution plate flows through that clearance onto the coffee powder. The water distribution plate may be removed from the vessel and laid onto a surface with its feet down as a base plate for the vessel, thus collecting water that might still pass through the filter. A rim protruding from the circumference of the water distribution plate prevents water from flowing down when the same is used as a base plate.
