Abstract:
1. A container for the filtration of liquid, comprising: a cup, which is at least partly filled with a filter material, wherein the cup has an upper peripheral flange with an upwardly facing surface and at least one outlet window at a bottom of the cup for the liquid to exit the cup, and a cover having an outer peripheral flange with a downwardly facing surface mounted on the upwardly facing surface of upper peripheral flange of the cup, wherein the cover has at least one inlet window for the liquid and at least one outlet window for air, wherein the at least one inlet window for liquid and the at least one outlet window for air are positioned above said upwardly facing surface and the at least one outlet window for air is positioned above the at least one inlet window for the liquid relative to said upwardly facing surface, wherein the at least one inlet window for the liquid has a first lattice structure with lattice openings, wherein the first lattice structure is positioned above said upwardly facing surface, wherein the at least one outlet window for air has a second lattice structure with lattice openings, wherein the second lattice structure defines a recess that extends inwardly into the container from a plane of the outlet window for air to a level below said upwardly facing surface for permitting a passage of air from an interior of the container to an exterior of the container.
