Patent attributes
Air is removed from a bottle by placing the apparatus over the bottle in a manner similar to that of a cork. A switch is activated by placement of the apparatus over the bottle and causes a pump to evacuate air from an interior of the bottle. A pressure sensor senses reduced pressure and shuts off the pump when a sufficiently low pressure is reached. An indicator also visually indicates that a vacuum state exists within the bottle. A temperature probe is provided, coupled to a display for visual readout of temperature of liquid within the bottle. A tilt sensor is provided to shut off the pump if the apparatus is tilted excessively. A button is provided which can be depressed to cause air to return into space in the bottle to return the bottle interior back to atmospheric pressure for removal of the apparatus.
