  • Publication number: 20250033368
    Abstract: An embodiment is a liquid container mounted on a liquid consumption apparatus including a liquid ejection head for ejecting a liquid and configured to store the liquid to be supplied to the liquid ejection head. The liquid container includes: a tank chamber to store the liquid; an inlet port which is provided above the tank chamber and into which the liquid is poured; and an outlet port which is provided to face the inside of the tank chamber and from which the liquid from the inlet port is discharged after moving through a channel with air-liquid exchange. Provided that a depth direction is a direction crossing a height direction and a right-left direction of the liquid consumption apparatus, the depth-direction center position of the outlet port is closer to the center of the tank chamber than the depth-direction center position of the inlet port is.
