Abstract

See full text

Methods and apparatus for liquid preservation according to various aspects of the present invention may comprise a vessel and a displacer. The displacer may be disposed in an interior volume defined by an interior surface of the vessel. The displacer may change the volume of the interior volume. An aperture at an apex of the displacer or vessel may allow air to escape from the interior volume as the displacer decreases the volume of the interior volume. An at least partially transparent displacement indicator may be positioned atop the aperture.
