Patent ID: 8172388

Claim:
A liquid container mountable in a liquid ejecting apparatus, the liquid container comprising: a liquid storage section that stores liquid; a liquid supply section through which the liquid stored in the liquid storage section is supplied to the liquid ejecting apparatus; an air communication section that allows the liquid storage section and an outside of the liquid container to communicate with each other; a bubble separation section that separates bubbles from the liquid; a vertical communication path that has an entrance communicating with the liquid storage section and an exit communicating with the bubble separation section; and a detection section that communicates with the liquid supply section and the bubble separation section, adapted to detect a depletion of the liquid stored in the liquid container by detecting when the detection section becomes filled with air; wherein the vertical communication path includes a plurality of cylindrical segments that each extend in a direction intersecting the vertical direction, and at least one connecting segment that connects the plurality of cylindrical segments to each other so as to obtain a single flow path, the vertical communication path being located downstream of the liquid storage section and upstream of the detection section through the bubble separation section.
