ABSTRACT:
A filter is provided for a brew cup for use in a hot beverage brewing machine such as a coffee brewing and dispensing machine. The filter is attached to the inside of a brew cup about halfway up the side walls and to the center of a guide spider axially movable within the brew cup. By this arrangement, spent grounds and fines are prevented from traveling with the brewed coffee or other beverage as it passes through the brew cup. When the brew cup mechanism is inverted and moved to the dumping station, this arrangement provides for the dumping of substantially all of the spent grounds and fines by a snap action applied to the spider and the filter material. The filter material is restrained from engaging the floor of the brew cup to prevent clogging and caking of the filter material and fines or spent grounds on the floor of the brew cup.
