## Abstract

The liquid container has a fixing lever, a first surface, a second surface, a third surface, and a corner. The fixing lever engages with a designated portion of the liquid consuming device, thereby fixing the liquid container in the liquid consuming device. The fixing lever is provided on the first surface. A liquid supply port for supplying liquid to the liquid consuming device is provided on the second surface. The third surface corresponds to a surface facing opposite the second surface or to a top surface of the liquid container in a state with the liquid container mounted on the liquid consuming device. The corner has a cutout in contact with the first surface and the third surface.

## Claims

### Claim 1

A liquid container to be mounted on a liquid consuming device, comprising:
a fixing lever that engages with a designated portion of the liquid consuming device, thereby fixing the liquid container in the liquid consuming device;
a first surface on which the fixing lever is provided;
a second surface on which a liquid supply port is provided for supplying liquid to the liquid consuming device;
a third surface, which corresponds to a surface facing opposite the second surface or to a top surface of the liquid container in a state with the liquid container mounted on the liquid consuming device;
a corner having a cutout in contact with the first surface and the third surface; and
a projected portion that projects further to the third surface side than a free end of the fixing lever in a direction along the first surface, the projected portion increasing a liquid capacity of the liquid container,
wherein the corner having the cutout is provided in the projected portion.

### Claim 2 (depends on 1)

The liquid container according to claim 1, wherein
the fixing lever has a fixed end fixed on the first surface, and the free end that is displaceable toward the first surface during mounting operation of the liquid container to the liquid consuming device, and
when seen in the direction along the first surface, the free end is located closer to the third surface than the fixed end is.

### Claim 3 (depends on 2)

The liquid container according to claim 2, wherein
the cutout of the corner is provided near a position of the free end when the free end of the fixing lever is displaced toward the first surface.

### Claim 4 (depends on 2)

The liquid container according to claim 2, wherein
the cutout of the corner meets the first surface near a position of the first surface which is opposite to the free end of the fixing lever when the free end is displaced toward the first surface.

### Claim 5 (depends on 1)

The liquid container according to claim 1, wherein
the cutout of the corner is formed by a flat surface.

### Claim 6 (depends on 3)

The liquid container according to claim 3, wherein
the cutout of the corner meets the first surface near a position of the first surface which is opposite to the free end of the fixing lever when the free end is displaced toward the first surface.

### Claim 7 (depends on 1)

The liquid container according to claim 1, wherein the cutout of the corner is formed by a curved surface.

### Claim 8 (depends on 1)

The liquid container according to claim 1, wherein the cutout of the corner is formed by a combination of flat and curved surfaces.
