  • Patent number: 5176830
    Abstract: A filter support fits inside a disposable coffee filter within the filter basket of an automatic drip coffee maker to prevent the side walls of the coffee filter from collapsing while coffee is being brewed. The filter support includes a base frame which rests on the bottom of the coffee filter, and a plurality of retaining members extending upwardly from the base frame for engaging the side walls of the coffee filter. The base frame includes first and second sets of horizontally extending cross members disposed at an angle to one another such that the cross members of each set intersect and join the cross members of the other set. The retaining members extend upwardly from the ends of the cross members and terminate in a free upper end. The cross members may include a downwardly extending portion which forms a leg to support the cross members in vertical spaced relation with respect to the bottom of the coffee filter.
