ABSTRACT:
A drip coffeemaker basket and filter assembly is provided comprising a cup-shaped basket supporting a matching water permeable filter and the basket is generally funnel-shaped with a substantially flat bottom wall of spaced supporting means defining a fixed opening water passage where the supporting means may be spaced radiating ribs. A second adjacent and larger cross-section supporting shelf is spaced above the bottom wall and supports the filter thereon. A convex curved surface connects the shelf and the supporting means whereby the filter seals on the convex surface inversely to the coffee quantity in the filter and automatically varies the effect of filtering area directly with the coffee quantity in the filter providing a single molded unit with non-movable or replaceable parts that automatically adjusts itself for larger and smaller quantities for the correct brew.
