Abstract

A liquid storage container includes a liquid storage body storing ink supplied to a printer consuming the ink. The liquids storage body includes an ink chamber which can store the ink, a filler port through which ink can be poured into the ink chamber, a lead-out port which leads out the ink stored in the ink chamber to the printer side, and a lead-out channel which connects a channel opening formed in the ink chamber and the lead-out port.

Claims

1. A liquid storage container comprising:

a liquid storage body for storing liquid to be supplied to a liquid consumption apparatus consuming the liquid,

wherein the liquid storage body includes;

a liquid storage chamber;

a filler port;

a lead-out port which leads the liquid stored in the liquid storage chamber out to the liquid consumption apparatus side; and

a liquid channel which connects a channel opening formed in the liquid storage chamber and the lead-out port, the liquid channel including;

an inclined channel portion having a lead-out port side end and a channel opening side end, wherein when the liquid storage body is the posture in which the liquid storage body is used, the inclined channel portion extends in a direction intersecting a horizontal direction, and the lead-out port side end is positioned from the channel opening side end in a direction that is opposite from the direction of gravity;

a curved channel portion bent with respect to the inclined channel portion; and

a connection channel portion connecting the channel opening and the curved channel portion to each other.

2. The liquid storage container according to claim 1,

wherein the connection channel portion includes a filter.

3. The liquid storage container according to claim 1,

wherein the channel opening is opened to a bottom surface positioned at the gravity direction side in the liquid storage chamber when the liquid storage body is in the posture in which the liquid storage body is used.

4. The liquid storage container according to claim 1,

wherein the liquid storage chamber includes a horizontally inclined rib portion which extends in a direction intersecting the horizontal direction when the liquid storage body is in the posture in which the liquid storage body is used.

5. The liquid storage container according to claim 1,

wherein the inclined channel portion is positioned at the gravity direction side of the liquid storage chamber when the liquid storage body is in the posture in which the liquid storage body is used.

6. The liquid storage container according to claim 1,

wherein a cross-sectional area of the inclined channel portion is larger than a cross-sectional area of the connection channel portion.

7. The liquid storage container according to claim 1, further comprising:

a first liquid storage chamber in which the filler port is formed;

a second liquid storage chamber which communicates with the first liquid storage chamber via a communication opening; and

a partition wall which intersects a filler port formation surface in which the filler port is formed and partitions the liquid storage chamber into the first liquid storage chamber and the second liquid storage chamber;

wherein a surface of the communication opening that is at a directional side of the communication opening that is opposite from the gravity directional side, is inclined in a direction intersecting the horizontal direction when the liquid storage body is in the posture in which the liquid storage body is used.

8. The liquid storage container according to claim 7,

wherein the second liquid storage chamber further includes an intersection rib portion which intersects the filler port formation surface,

wherein a communication opening, which brings spaces separated by the intersection rib portion into communicate with each other, is formed in the intersection rib portion,

wherein a ventilation opening is formed in each of the partition wall and the intersection rib portion at positions that are closer to the filler port formation surface side than is the communication opening, and

wherein the ventilation opening formed in the partition wall is located closer to the filler port formation surface than is the ventilation opening formed in the intersection rib portion.
