Abstract

A liquid container unit includes: a liquid container including: a plurality of liquid storage portions; and a plurality of injection ports which are provided to the respective plurality of liquid storage portions, and are configured to enable injection of liquid into the plurality of liquid storage portions; and an injection port cover which is provided to the liquid container so as to be rotatable and is configured to cover the plurality of injection ports so as to be openable and closable, the injection port cover including a plurality of stopper members configured to close the plurality of injection ports when the injection port cover is closed.

First claim

What is claimed is:

1. A liquid container unit comprising:
a liquid container; and
an integral injection port cover,
wherein the liquid container comprises:
a plurality of liquid storage portions; and
a plurality of injection ports which are provided to the respective plurality of liquid storage portions, and are configured to enable injection of liquid into the plurality of liquid storage portions; and

wherein the integral injection port cover integrally includes a plurality of stopper members provided in one to one with the plurality of injection ports, and wherein by rotating the integral injection port cover with respect to the liquid container, a state of the plurality of stopper members changes between a state in which the plurality of injection ports are opened and a state in which the plurality of injection ports are closed.

2. A liquid container unit according to claim 1 , wherein the injection port cover is rotatable with respect to the liquid container about a rotary axis parallel to an array direction of the plurality of liquid storage portions.

3. A liquid container unit according to claim 2 , wherein at least two injection ports of the plurality of injection ports are different from each other in radial distance from the rotary axis to respective centers of the injection ports.

4. A liquid container unit according to claim 3 , wherein the plurality of injection ports are different from each other in radial distance from the rotary axis to respective centers of the injection ports.

5. A liquid container unit according to claim 4 , wherein the plurality of injection ports are arranged along the array direction in a descending order of radial distances from the rotary axis to the respective centers of the injection ports.

6. A liquid container unit according to claim 3 , wherein an injection port, which is one of the plurality of injection ports and is largest in radial distance from the rotary axis to a center of the injection port, is an injection port of a liquid storage portion, which is one of the plurality of liquid storage portions configured to store liquids of a plurality of colors, and is configured to store liquid of a color having a lowest brightness.

7. A liquid container unit according to claim 6 , wherein the color having the lowest brightness is black.

8. A liquid container unit according to claim 3 , wherein an injection port, which is one of the plurality of injection ports and is largest in radial distance from the rotary axis to a center of the injection port, is arranged on a plane which is different from a plane on which other injection port is arranged.

9. A liquid container unit according to claim 2 , wherein the injection ports are formed in an inclined surface of the liquid storage portion.

10. A liquid container unit according to claim 1 , wherein the injection port cover comprises a plurality of injection port covers corresponding to the plurality of liquid storage portions, and the plurality of injection port covers are individually openable and closable.

11. A liquid container unit according to claim 10 , wherein an injection port cover corresponding to a liquid storage portion, which is one of the plurality of liquid storage portions configured to store liquids of a plurality of colors, and is configured to store liquid of a color having a lowest brightness, is individually openable and closable.

12. A liquid container unit according to claim 1 , wherein the plurality of stopper members are made of a material having rubber elasticity.

13. A liquid container unit according to claim 12 , wherein the material having rubber elasticity comprises chlorinated butylene rubber.

14. A liquid container unit according to claim 1 , wherein the injection port cover is rotatable with respect to the liquid container about a rotary axis, and the rotary axis is arranged on an upper end side of the liquid container.

15. A liquid container unit according to claim 14 , wherein, when a side of the liquid container on which the injection ports are formed is a front side, and a side opposite to the front side is a rear side, the rotary axis is arranged on the rear side of the liquid container.

16. A recording apparatus, comprising:
the liquid container unit of claim 15 ; and
a recording head configured to eject liquid fed from the liquid container unit.

17. A liquid container unit according to claim 1 , wherein the injection port cover is rotatable with respect to the liquid container about a rotary axis, and the rotary axis is arranged on a lower end side of the liquid container.

18. A liquid container unit according to claim 17 , wherein, when a side of the liquid container on which the injection ports are formed is a front side, and a side opposite to the front side is a rear side, the rotary axis is arranged on the front side of the liquid container.

19. A liquid container unit according to claim 1 , wherein the injection ports are formed in an inclined surface of the liquid storage portion.

20. A recording apparatus, comprising:
the liquid container unit of claim 1 ; and
a recording head configured to eject liquid fed from the liquid container unit.
