    Abstract: A liquid container comprises a liquid supply port provided in a bottom wall, a first chamber configured to contain a liquid, a second chamber configured to contain the liquid and to include at least one sub-chamber having a smaller dimension in the X direction than that of the first chamber, a partition wall configured to part the first chamber from the second chamber, and a connecting hole configured to connect the first chamber with the second chamber. The second chamber is connected with the liquid supply port, and the first chamber is connected with the liquid supply port via the connecting hole and the second chamber. The liquid contained in the first chamber is flowed from the connecting hole into the second chamber and is subsequently introduced through the sub-chamber to the liquid supply port.

    Abstract: A liquid supply unit includes a first wall, a second wall that opposes the first wall, a third wall that intersects the first wall and the second wall, a fourth wall that intersects the second wall and opposes the third wall, a fifth wall that intersects the first wall, the second wall, the third wall, and the fourth wall, a sixth wall that intersects the first wall, the second wall, the third wall, and the fourth wall, and opposes the fifth wall, and a seventh wall that intersects the fifth wall and the sixth wall and is located between the first wall and the fourth wall. The direction from the third wall toward the fourth wall is a direction parallel to a moving direction in which the carriage moves back and forth. The seventh wall inclines relative to the gravity direction toward the third wall side.

    Abstract: A liquid container includes: a flexible bag provided with a liquid container that internally contains the liquid; a liquid outlet member attached to a one end portion of the bag; and a connection member that is attached to the one end portion of the bag so as to cover the liquid outlet member and a portion of the one end portion of the bag from the outside. The bag includes a sealed portion on an outer periphery side relative to the liquid container, the sealed portion includes a one end portion-side sealed portion, and a first width, which is a width of the one end portion-side sealed portion in at least a surrounding region of the connection member, is larger than a second width, which is a width of the sealed portion at other ends of the bag.

    Abstract: A liquid storage container includes a liquid storage part, a liquid supply part, a liquid outflow part, and a cover. The liquid storage part stores a liquid. The liquid supply part has a liquid supply port defining an opening by which the liquid is supplied to a liquid jet apparatus from the liquid storage part. The liquid outflow part is made of a porous material. The liquid outflow part is disposed inside of the liquid supply port and allows the liquid to flow out to the liquid jet apparatus from the liquid storage part. The cover includes a sealing part contacting with the liquid supply part and sealing off the liquid supply port, the sealing part and the liquid outflow part defining a space therebetween, and a contact part made of a non-porous material, the contact part contacting with a part of the liquid outflow part.
