Liquid container and liquid ejection device

A liquid container for supplying liquid to a liquid ejection device, comprising:

• when three directions that orthogonally intersect each other are denoted as a D direction, a T direction, and a W direction,
• a positive direction of the D direction is denoted as a +D direction, and the direction opposite to the +D direction is denoted as a −D direction,
• a direction in which the size of an external shape of the liquid container is smallest is the T direction, and
• a direction orthogonal to the D direction and the T direction is the W direction,
• the D direction and the W direction extending in a horizontal direction in a state in which the liquid container is attached to the liquid ejection device,
• 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 on the −D direction side;
• and
• a connection member that is attached to the one end portion so as to cover the liquid outlet member and a portion of the one end portion from the outside,
• wherein 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 that is formed along the W direction at an end on the −D direction side of the flexible bag,
• the one end portion-side sealed portion comprises a surrounding region that is adjacent to the connection member in the W direction,
• a first width, which is a width of the one end portion-side sealed portion in at least the surrounding region, is larger than a second width, which is a width of the sealed portion at other ends of the bag, and
• a +D direction end of a portion of the one end portion-side sealed portion is located on the +D direction side relative to a +D direction end of the connection member.
