Percolator including pump-type dispenser

A percolator/dispenser comprising:

• an insulated vessel;
• a spout extending between the interior and the exterior of the vessel;
• a perforated basket inside the vessel;
• percolator means, disposed within the vessel, for causing a liquid contained in the vessel to percolate through the basket;
• a cap mounted to the vessel and movable between first and second positions;
• a seal mounted between the cap and a wall of the vessel to seal a space between the cap and the wall;
• first valve means, in communication with the space, for directing air from the exterior of the vessel into the space when the cap is moved from the first position to the second position;
• second valve means, in communication with the space, for directing air from the space into the vessel when the cap is moved from the second position to the first position;
• third valve means for providing a normally open vent path between the exterior of the vessel and an upper portion of the interior of the vessel, said third valve means operative automatically to close the vent path when the cap is moved from the second to the first position in order to allow momentary pressurization of the vessel;
• said first, second, and third valve means cooperating to cause liquid to be pumped out of the spout when the cap is moved from the second to the first position, while allowing the vessel to vent during normal operation of the percolator means.

A percolator/dispenser comprising:

• an insulated vessel which defines an upper opening;
• a lid sized to seal the opening;
• a percolator system positioned within the vessel, said system including a percolator tube extending between a lower and an upper point in the vessel and a heater adapted to force heated liquid up the tube;
• a perforated basket mounted in the vessel below the upper point such that liquid forced up the tube percolates through the basket, said opening sized to permit removal of the basket from the vessel;
• a spout extending from a point near the bottom of the interior of the vessel, up to an upper edge of the interior of the vessel, and then to the exterior of the vessel;
• means for defining a normally open vent path between an upper portion of the spout and an upper portion of the interior of the vessel;
• a manually operated pressure pump, included in the lid, for pumping air from the outside of the pressure vessel to the inside of the vessel, and pump comprising:
• a cap mounted on the lid to define a chamber therebetween, said cap movable between an upper position and a lower position, the volume of the chamber being greater when the cap is in the upper position than when the cap is in the lower position;
• a first one-way valve for passing air from the exterior of the vessel into the chamber as the cap moves to the upper position;
• and
• a second one-way valve for passing air from the chamber into the vessel as the cap moves to the lower position;
• and
• a vent valve, responsive to movement of the cap from the upper to the lower position, for momentarily sealing the vent path to permit momentary pressurization of the vessel and the dispensing of liquid from the spout.
