ABSTRACT:
A container of evacuated double wall construction has an open neck for receiving a beverage after the beverage has been heated to a desired temperature. A stopper member receivable in the open neck incorporates an evacuated electric light bulb covering a major portion of the cross sectional area of the neck to provide further heat insulation and also radiate heat onto beverage within the container. Regulation of the heat to maintain the beverage at a desired constant temperature is accomplished by a pressure actuated switch incorporated in the stopper member. When water is used as the beverage, the heated water can be passed from the container through an outlet spout to a cartridge housing including pay out and take up spools for a series of packets connected together to form a ribbon. Successive packets may be positioned under the spout and include coffee beans, the cartridge including a cup receiving area so that coffee can be brewed directly into a cup.
