  • Patent number: 4865737
    Abstract: A cylinder having both ends opened is structured of loosely woven metal or plastic wire. The cylinder is sized to fit vertically in a coffee maker filter basket inside a disposable coffee filter as a filter support. The filter support prevents the walls of the disposable filter from collapsing over the coffee grounds thus reducing chances of coffee grounds being released into the coffee pot. The rounded cylinder comprising this filter support is sized to fit and function in all shapes of coffee maker filter baskets and in other coffee making filter funnels, round, square, and frusto-conical. The filter support of the immediate invention is reuseable.
