Abstract

An infusion coffee maker includes a cover, a filter assembly, a drip cup, a retaining plate, and a stop. The drip cup has a central through hole at the bottom, and the filter assembly also has a through hole in the center. The bottom periphery of the drip cup extends downwardly to form an extended wall which is provided with spaced elongated holes and legs. The retaining plate includes a ferrule, a positioning rib element disposed inside and integrally connected to the ferrule, and spaced slots for receiving the legs of the drip cup. The ferrule is fitted below the drip cup within the space defined by the extended wall. The stop is inserted through the through holes of the drip cup into a hole in the center of the positioning rib element of the retaining plate. When the drip cup is placed on a planar surface, the ferrule slips downwardly along the elongated hole due to its own weight. A liquid such as coffee poured into the drip cup causes the stop to be tightly held in the through hole of the drip cup to avoid leakage. When the drip cup is placed on a container, the ferrule or the retaining plate at the bottom of the drip cup is pushed upwardly so that the stop disengages from the through hole of the drip cup to allow discharge of coffee into the container below.
