A printing liquid container fits to one of first and second tanks each including a fitted portion. The printing liquid container includes a first member having a supply port, and a second member having a valve configured to open or close the supply port. The first member and the second member are rotatable with respect to each other between a first state and a second state. The valve closes the supply port in the first state and opens the supply port in the second state. The first member has a fitting portion configured to fit to the fitted portion. The second member is rotatable with respect to the fitted portion when at least a portion of the second member is inserted into the fitted portion. The first member does not rotate by the rotation of the second member due to the fitting between the fitted portion and the fitting portion.

Printing liquid container, container set, and system including printing liquid containers and tanks

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.
