    Abstract: A new fluid fill piston pump device comprising a piston chamber defined by an inner surface. Inside this piston chamber is an oscillating piston having an outer surface forming a sliding seal to the inner surface of the piston chamber. The oscillating piston separates the piston chamber into a gas chamber and a fluid chamber such that the sum of the two chambers remains the same as the piston oscillates changing the volume of the two chambers in opposition. As fluid is pumped into the container from the fluid chamber of the piston chamber, gas is drawn from the container into the gas chamber in the same action.

    Abstract: An cooler capable of achieving a sufficient temperature gradient between an inside of the cooler and an outside of the cooler such that at least a partial vacuum forms within the cooler may include an enclosure defined by at least one wall and a lid. The lid may form a relatively airtight seal with a wall of the cooler when in a closed position. A vacuum release assembly may be disposed in one of the walls or lid of the cooler, the assembly being capable of reducing a pressure differential between the enclosure and the outside of the cooler.
