  • Patent number: 4874112
    Abstract: A dispenser for pleated frusto-conical coffee filters has a housing provided with an opening preferably in the face normally forming the bottom, and one or more side openings communicating with the bottom opening. The bottom opening leaves shelves on opposite sides that support a stack of filter papers positioned so that the larger end rests on these shelves. Tabs on the filter papers facilitate the withdrawal of the papers one-by-one, and turning the stack inside-out from the initially pleated condition disengages the edges of the sheets for easier separation.
