Abstract: A plastic decanter and method of use having inward sloping side walls and a broad base construction which interfits with a concave-shaped warmer plate mounted in the warming deck of a conventional coffee brewing machine, the decanter receiving freshly brewed coffee from a brewing assembly with the decanter containing over half of the coffee mass below the horizontal midpoint permitting a reduction in the required heat to be generated by the warmer plate heating element for avoiding burning the coffee, while the sloping sidewalls, a closure lid and the tight interfit between the decanter and the warmer plate contribute to a reduction in the air convection heat losses for maintaining the coffee fresh for at least four hours, the plastic decanter being relatively unbreakable for eliminating a potential hazard while being utilized as a lightweight serving container.

Abstract: A drip-type coffee maker with efficient heat transfer and minimal heat loss keeps coffee at the optimum temperature for proper flavor over an extended period of time. A closed-top decanter formed entirely of plastic heat insulating material fits into a well which contains a recessed aluminum warming plate. The warming plate is heated to a temperature only slightly above the desired temperature of the coffee. A warming plate adapter is provided for converting existing coffee makers.
