Liquid container and liquid consumption device

A liquid container configured to be fitted to a carriage of a liquid jetting device that includes the carriage where a head is provided and that jets, while making the carriage reciprocate, a liquid from the head, the liquid container configured to store the liquid to be supplied to the head, the liquid container comprising:

• a liquid storage portion configured to store the liquid inside;
• an undulation reduction portion provided in the liquid storage portion and including a wall surface configured to reduce undulation of the liquid and configured to be directed in a direction of gravity in a fitting posture where the liquid container is fitted to the carriage;
• and
• a support portion configured to support the undulation reduction portion such that, in the liquid storage portion, the undulation reduction portion is allowed to swing together with the liquid and that a movement of the wall surface along the direction of gravity in the fitting posture is restricted, and the support portion includes:
• a bottom plate portion arranged below the wall surface so as to face a bottom surface of the liquid storage portion in a state where the bottom plate portion is allowed to swing together with the liquid;
• and
• a coupling portion extending upward from the bottom plate portion in the fitting posture and that couples together the bottom plate portion and the undulation reduction portion arranged in a position away from the bottom plate portion.

A liquid consumption device comprising:

• a head configured to jet a liquid;
• a carriage including the head and configured to reciprocate;
• and
• a liquid container configured to be fitted to the carriage and store the liquid to be supplied to the head,
• wherein the liquid container includes:
• a liquid storage portion configured to store the liquid inside;
• an undulation reduction portion provided in the liquid storage portion and including a wall surface configured to reduce undulation of the liquid and configured to be directed in a direction of gravity in a fitting posture where the liquid container is fitted to the carriage;
• and
• a support portion configured to support the undulation reduction portion such that the undulation reduction portion is allowed to swing together with the liquid, a movement of the wall surface of the undulation reduction portion along the direction of gravity is restricted, and that, when in the fitting posture, a position of a surface of the liquid in the liquid storage portion is lowered beyond a predetermined position, at least part of the wall surface is located higher than the surface of the liquid.
