Abstract
A percolator/dispenser is disclosed which includes an insulated container having a hinged lid. A percolator heater, tube, and basket are mounted inside the container, and a manually operated pressure pump is included in the lid of the container. This pressure pump operates to pump air from the outside of the container to the inside of the container when operated. A normally open vent path is provided between a spout of the container and the upper portion of the interior of the container. When the manually operated pump is operated, a vent valve is controlled to close this vent path in order to seal the container such that air introduced into the container by means of the pump operates to force liquid out of the spout of the container.
