Liquid container and manufacturing method therefor
First Claim
1. A liquid container including a liquid chamber, comprising:
- a light emitter;
an electrical contact configured to receive a signal for causing the light emitter to emit light;
a display portion configured to direct the light emitted from the light emitter toward an outside of the liquid container to display information about states of the liquid container;
a latch lever elastically deformable and having a latching portion spaced from a first side of the liquid container, the first side being positioned between the latching portion and the liquid chamber; and
a liquid supply port disposed at a second side of the liquid container,wherein the electrical contact is disposed at a position which is between the latching portion and the liquid supply port when the liquid container is viewed in a direction perpendicular to the second side and which is between the latching portion and the second side when the liquid container is viewed in a direction perpendicular to the first side, andwherein the display portion is disposed adjacent to an upper portion, in use, of the first side.

Abstract
A liquid container detachably mountable to a mounting portion of an ink jet recording apparatus, and which includes a liquid chamber, a light emitter, an electrical contact which receives a signal for light emission by the light emitter, and a display portion which directs emitted light from the light emitter toward an outside of the liquid container. A latch lever is elastically deformable and has a latching portion spaced from a first side of the liquid container, the first side being between the latching portion and the liquid chamber. A liquid supply port is disposed at a second side of the liquid container. The electrical contact is disposed at a position which is between the latching portion and the liquid supply port as seen facing both of the first and second sides, and the display portion is disposed adjacent to an upper portion, in use, of the first side.

11. A liquid container including a liquid chamber, comprising:
-
a light emitter; an electrical contact; a controller (i) storing container discrimination information indicative of a color of liquid in the liquid container, and (ii) configured (ii-a) to receive a command for causing the light emitter to emit light and color information received via the electrical contact and (ii-b) to cause the light emitter to emit light in response to the received command if the received color information corresponds to the stored container discrimination information; a display portion configured to direct the light toward an outside of the liquid container to display information about states of the liquid container; a light guide portion having a light incident portion on which the light emitted from the light emitter is incident and the display portion, the light guide portion being configured to guide the light from the light incident portion to the display portion; a latch lever elastically deformable and having a latching portion spaced from a first side of the liquid container, the first side being positioned between the latching portion and the liquid chamber; and a liquid supply port disposed at a second side of the liquid container, wherein the electrical contact is inclined relative to the first and second sides at a position which is between the latching portion and the liquid supply port when the liquid container is viewed in a direction perpendicular to the second side and which is between the latching portion and the second side when the liquid container is viewed in a direction perpendicular to the first side, and wherein the display portion is disposed adjacent to an upper portion, in use, of the first side. - View Dependent Claims (12, 13)
