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 outside the container to the inside of the container when operated. A discharge spout is movable between a vented position, a pump position, and a sealed position. A pressure lock system prevents the spout from being moved from the sealed position to the pump position when excessive pressure is present within the container. A lid stop system prevents the lid from being closed when the spout is in the pump position. A lid lock system prevents the lid from being opened when the container is pressurized.
