1. A container, comprising:
a hollow cylinder having a closed bottom, an open top, and a spirally threaded inner wall extending between the closed bottom and the open top;
a lid configured to threadably engage the inner wall of the hollow cylinder and substantially seal liquid contained within the cylinder from exposure to air outside the cylinder, the lid having a center, a top surface, a perimeter, and a bottom surface; and
a leakage pathway formed between the perimeter of the lid and the inner wall;
the lid further configured to evacuate air from the hollow cylinder through the leakage pathway by compression of the lid against the liquid contained in the cylinder;
the leakage pathway continuously open between the perimeter of the lid and the inner wall as the lid compresses the liquid to permit leakage of the liquid through the leakage pathway to provide a visual indication of the leakage at the top surface of the lid.
