Abstract
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.

An apparatus for preserving a liquid, comprising:
- a vessel comprising an interior surface defining an interior space to contain the liquid, wherein the vessel includes a top portion having an aperture defined therethrough;
- an interior surface of the top portion, wherein the top surface slopes significantly downward from the aperture to a side of the vessel;
- and
- a displacer disposed within the vessel, wherein the displacer includes a selectably movable surface within the interior volume, wherein movement of the selectably movable surface changes a volume of the interior volume.
An apparatus for preserving a liquid, comprising:
- a vessel comprising an interior surface defining an interior containing the liquid;
- a displacer disposed within the vessel, wherein the displacer includes a movable element within the interior defining a movable surface subjecting the liquid to compression within the interior, driving air out of the vessel interior, and changing a level of the liquid.
An apparatus for preserving a liquid, comprising:
- a vessel comprising:
- an interior surface defining an interior space to contain the liquid;
- and
- an aperture formed in the top of the vessel, wherein the aperture is positioned above the top interior space;
- a displacer disposed within the vessel, comprising:
- an outer rim sealingly engaging the interior surface of the vessel, and
- wherein:
- the displacer is selectably movable vertically within the interior space parallel to the interior surface and below the open top;
- and
- a movement of the displacer changes the volume of the interior space and a level of the liquid.
