7. A liquid container for supplying a liquid to a liquid ejection apparatus, comprising:
-
a liquid chamber provided to store the liquid; a liquid inlet connected with the liquid chamber and provided to fill the liquid into the liquid chamber; and a liquid discharge port provided to have one end connecting with the liquid chamber at a preset height from a bottom face of the liquid chamber and the other end open to outside, in a filling attitude of the liquid container in which the liquid is filled into the liquid chamber, the liquid discharge port causing the liquid stored in the liquid chamber to be flowed to outside, wherein the liquid container is installed such that the liquid discharge port is located below the liquid inlet, in a use attitude of the liquid container in which the liquid in the liquid chamber is supplied to the liquid ejection apparatus, and the liquid chamber has a liquid retainer connected with the one end of the liquid discharge port and provided to retain the liquid in the liquid chamber such that the liquid in the liquid discharge port is continuous with the liquid in the liquid chamber without the air, when attitude of the liquid container with the liquid chamber storing the liquid of not less than a predetermined amount is changed from the use attitude to the filling attitude. - View Dependent Claims (8, 9)

10. A liquid container for supplying a liquid to a liquid ejection apparatus, comprising:
-
a liquid chamber formed by a plurality of wall members to store the liquid; a liquid inlet provided to fill the liquid into the liquid chamber and to have one end open to outside and the other end open to the liquid chamber; a plug member provided to close the liquid inlet; an open-air flow path provided to introduce the outside air into the liquid chamber; and a liquid discharge port provided to supply the liquid stored in the liquid chamber to the liquid ejection apparatus, wherein the open-air flow path includes; an air chamber provided to have a predetermined volume; a first flow path provided to connect the air chamber to outside; and a second flow path provided to have an air-side opening at one end open to the air chamber and a liquid-side opening at the other end open to the liquid chamber and thereby connect the liquid chamber with the air chamber, wherein a meniscus is formed in the second flow path to retain the liquid, wherein the second flow path including the liquid-side opening and the air-side opening is located below the other end of the liquid inlet, in a use attitude of the liquid container in which the liquid in the liquid container is supplied to the liquid ejection apparatus, and a filling attitude of the liquid container in which the liquid is filled through the liquid inlet into the liquid chamber is a different attitude from the use attitude and causes the air-side opening to be located above the other end of the liquid inlet. - View Dependent Claims (11, 12, 13, 15)

14. A liquid container for supplying a liquid to a liquid ejection apparatus, the liquid container being set in a use attitude in which the liquid is supplied to the liquid ejection apparatus and in a filling attitude in which the liquid is filled into the liquid container, wherein the use attitude is a different attitude from the filling attitude,
the liquid container comprising: -
a liquid chamber formed by a plurality of wall members to store the liquid; a liquid inlet provided to fill the liquid into the liquid chamber; a liquid discharge port provided to supply the liquid in the liquid chamber to the liquid ejection apparatus; a lower limit element provided on a first wall member among the plurality of wall members, the first wall member being visible from outside, the lower limit element being used to detect, from outside, that liquid level in the liquid chamber reaches a first threshold value with consumption of the liquid in the liquid chamber in the use attitude; and an upper limit element provided on a second wall member among the plurality of wall members, the second wall member being visible from outside and being different from the first wall member, the upper limit element being used to detect, from outside, that the liquid level in the liquid chamber reaches a second threshold value as the liquid is filled through the liquid inlet into the liquid chamber in the filling attitude, wherein the first wall member is vertically-angled relative to a mounting surface on which the liquid container is mounted, in the use attitude, and the second wall member is vertically-angled relative to the mounting surface on which the liquid container is mounted, in the filling attitude.
