ABSTRACT:
Coffee filters formed by longitudinally spaced segments of a continuous tape of filter paper, connected by intact strips of said paper, the tape being rolled longitudinally to permit large numbers of said segments to be stored in a small space. The tape may be paid out from the roll and torn or otherwise separated from the tape for individual use. Each individual segment is provided with fold lines facilitating its formation into cup form, after separation from the tape, as required for use in most coffee making machines. Also provided is a dispenser container for the filter paper roll, the container being configurated to permit easy, one-at-a-time dispensing of the tape segments, and to prevent damage to the tape during dispensation.
