  • Patent number: 6224755
    Abstract: A coffee maker and a method of preparing coffee in which steam is applied to the coffee grinds prior to passing hot water through the coffee grinds. The coffee maker includes a controllable outlet valve disposed within a fluid path, between a water reservoir and a flow-through heater. In a first position, the outlet valve has a flow opening dimensioned sufficiently small that water exiting the outlet valve evaporates completely in the flow-through heater. In a second position, the outlet valve has a flow opening dimensioned sufficiently large that water exiting the outlet valve is heated in the flow-through heater without appreciable development of steam.

  • Patent number: 6189438
    Abstract: The invention is directed to a filtering device, a filter element therefor and a method of manufacturing the filter element (28) from filter paper. The filter element (28) has a receiving cavity (76) to be filled with extractable materials such as coffee grounds or tea leaves. Following contact with hot water, the extractable materials deliver extractive substances to the water, resulting in a brewed beverage that is drained from the filter element (28). During this process, the filter element (28) is held by the filter support (1) by way of a supporting member which includes a rim (39) formed on the filter element (28) and having a bearing surface (40), and a supporting surface (24) formed on the filter support (1). The rim (39) of the filter element (28) is reinforced mechanically by providing the filter paper with exposed pleats (42, 51, 52) which cooperate with corresponding elevations (115) and recesses (79) formed on the supporting surface (24) of the filter support (1).
