Abstract:
A liquid tank includes a liquid supply portion, a first liquid chamber, a liquid communication flow path and an air communication flow path. The liquid communication flow path includes an upstream end which is connected to the first liquid chamber, a rising flow path which is located on a downstream side with respect to the upstream end and which extends upward in a mounting state, a lowering flow path which is located on the downstream side with respect to the rising flow path and which extends downward in the mounting state and a downstream end which is located on the downstream side with respect to the lowering flow path and which is connected to the liquid supply portion. In the mounting state, the liquid supply portion is located lower than the downstream end and extends downward toward a liquid supply port.

Claim (Index 1):
A liquid tank which is mounted to a carriage including a liquid ejection head, the liquid tank comprising:\n a liquid supply portion which includes a liquid supply port that receives a liquid introduction needle included in the liquid ejection head; a first liquid chamber configured to store a liquid to be supplied to the liquid supply portion; a liquid communication flow path through which the first liquid chamber is in fluid communication with the liquid supply portion, the liquid communication flow path forming a flow path that is upwardly convex in a mounting state where the liquid tank is mounted to the carriage; and an air communication flow path through which the first liquid chamber is in communication with the liquid supply portion, the air communication flow path connected to the first liquid chamber in a position higher than a position of connection of the liquid communication flow path and the first liquid chamber in the mounting state, wherein in a direction of flow of the liquid from the liquid tank toward the liquid ejection head, the liquid communication flow path includes:\n an upstream end which is connected to the first liquid chamber; \n a rising flow path which is located on a downstream side with respect to the upstream end and which extends upward in the mounting state; \n a lowering flow path which is located on the downstream side with respect to the rising flow path and which extends downward in the mounting state; and \n a downstream end which is located on the downstream side with respect to the lowering flow path and which is connected to the liquid supply portion, and \n in the mounting state, the liquid supply portion is located lower than the downstream end and extends downward toward the liquid supply port.
