摘要

A liquid container includes a liquid containing bag which contains a liquid and has at least two sheets of flexible film, and a liquid supply portion which supplies the liquid to a liquid consuming apparatus. The liquid supply portion is welded with the two sheets of film at one end of the liquid containing bag, and has a liquid supply path, a first chamber, and a second chamber. The first chamber communicates with the liquid supply path and an interior of the liquid containing bag. The second chamber communicates with the interior of the liquid supply portion. The first chamber is partitioned by a first rib, and the second chamber is partitioned from the first chamber by a second rib separated from the first rib. The first chamber communicates with the second chamber via a gap between the second rib and the one sheet of film.
