A liquid storage container comprising:

• a liquid reservoir part configured to reserve a liquid;
• a partition wall configured to separate an inside of the liquid reservoir part and an outside of the liquid reservoir part;
• a through hole configured to penetrate the partition wall in a first direction;
• a movable support member inserted into the through hole, the movable support member being capable of moving in the through hole in the first direction, and including (1) a first opening communicating with the outside of the liquid reservoir part, and (2) a second opening communicating with the first opening;
• a first seal member disposed on the movable support member;
• and
• a biasing member configured to bias the first seal member so that the first seal member is positioned at a first position where the first seal member is in contact with the partition wall,
• wherein an opening area of the second opening is covered by the partition wall when the first seal member is at the first position,
• wherein the movable support member includes a receiving part configured to receive an external force, and
• wherein by moving the movable support member by receiving the external force, the first seal member moves from the first position to a second position where at least a part of the second opening is exposed from the partition wall, and the inside of the liquid reservoir part is communicated with the outside of the liquid reservoir part through the first opening and the second opening.
