Abstract
A printing liquid container includes first and second members having a supply port and a valve, respectively. The members rotate with respect to each other between first and second states. The valve closes and opens the supply port in the first and second states, respectively. The first and second members have first and second fitting portions, respectively. The fitting portions fit to a fitted portion of a tank in the first state. The second fitting portion allows rotation of the second member with respect to the fitted portion when the first fitting portion are fitted to the fitting portion. The first member does not rotate together with the second member due to fitting between the fitted portion and the first fitting portion. The second member cannot be removed from the fitted portion due to fitting of the second fitting portion to the fitted portion in the second state.
