Abstract

A liquid replenishing container configured to replenish recording liquid to a liquid storage container having a receiving portion of the recording liquid, includes a holding portion that holds recording liquid to be replenished to the liquid storage container; and an injecting portion that has an opening to discharge the recording liquid in the holding portion, and that is inserted into the receiving portion of the liquid storage container, wherein the opening opens so as to face an inner wall of the receiving portion.

First claim

What is claimed is:

1. A liquid replenishing bottle configured to replenish recording liquid to a liquid discharging device, wherein the liquid discharging device includes (A) a recording head and (B) a liquid storage container for supplying the recording liquid to the recording head, and wherein the liquid storage container includes (1) a liquid storage portion containing the recording liquid replenished from the liquid replenishing bottle and (2) a receiving portion being provided on an upper side of the liquid storage portion, the liquid replenishing bottle comprising:
a holding portion that holds the recording liquid to be replenished to the liquid discharging device; and
an injecting portion for insertion into the receiving portion in an inserting direction having a gravity direction component,
wherein the injecting portion includes (1) an opening to discharge the recording liquid in the holding portion and (2) an engaging portion that is engageable with an engaged portion of the receiving portion,
wherein the opening is opened in a direction intersecting with the inserting direction, and
wherein the engaging portion positions the injecting portion with respect to the receiving portion so that the opening faces a predetermined direction with respect to an inner wall of the receiving portion.

2. The liquid replenishing bottle according to claim 1 , wherein the injecting portion includes a tip portion which protrudes at an end of the injecting portion in a direction that intersects with the inserting direction and that is toward an inner wall of the receiving portion, and
wherein the opening opens in the tip portion in the direction in which the tip portion protrudes.

3. The liquid replenishing bottle according to claim 1 , wherein the injecting portion includes a curved tip portion which protrudes at an end of the ejecting portion with curving from the inserting direction toward an inner wall of the receiving portion, and
wherein the opening opens in the curved tip portion in a direction in which the curved tip portion protrudes.

4. The liquid replenishing bottle according to claim 1 , wherein a width of the opening in a circumferential direction increases in direction to an end of the injecting portion.

5. The liquid replenishing bottle according to claim 1 , wherein the opening is disposed on both sides, as a pair, in a direction orthogonal to the inserting direction.

6. The liquid replenishing bottle according to claim 1 , wherein the opening faces a direction intersecting the inserting direction.

7. A liquid replenishing system comprising:
the liquid replenishing bottle according to claim 1 ,
wherein the receiving portion of the liquid storage container includes (1) a receiving port to which the injecting portion is inserted, and to which the recording liquid is injected via the opening of the injecting portion, which is inserted into the receiving port, and (2) a region on an inner wall that faces the opening.

8. The liquid replenishing system according to claim 7 , wherein the receiving portion includes an inclined surface in the region on the inner wall facing the opening, and
wherein the inclined surface is inclined such that the recording liquid, which is discharged from the opening toward the inner wall of the receiving portion, contacts the inner wall of the receiving portion and then moves in a direction toward the liquid storage portion.

9. The liquid replenishing system according to claim 8 , wherein the inclined surface is inclined so as to be distant from the receiving port in a direction orthogonal to the inserting direction of the injecting portion, as the distance from the receiving port increases.

10. The liquid replenishing system according to claim 7 , wherein the receiving portion includes:
a first wall face that faces the injecting portion on the inner wall on the side closer to the receiving port; and
a second wall face that faces the opening more distant from the injecting portion than the first wall face, on the inner wall on the side more distant from the receiving port than the first wall face.

11. The liquid replenishing system according to claim 10 , wherein the liquid storage container includes a protrusion at a position, on the outer surface of the receiving portion, corresponding to the second wall face.

12. The liquid replenishing system according to claim 11 , wherein a plurality of liquid storage containers are provided,
wherein the plurality of liquid storage containers are disposed adjacent to each other such that respective receiving portions of the plurality of liquid storage containers face a same direction, and
wherein each of respective protrusions of the plurality of liquid storage containers is disposed on the outer surface of the receiving portion, on one side in a direction where the plurality of liquid storage containers are adjacent to each other.

13. The liquid replenishing system according to claim 11 , wherein a plurality of liquid storage containers are provided,
wherein the plurality of liquid storage containers are disposed adjacent to each other such that respective receiving portions of the plurality of liquid storage containers face a same direction, and
wherein each of respective protrusions of the plurality of liquid storage containers is disposed on the outer surface of the receiving portion, at a position distant from a region facing another adjacent receiving portion.

14. The liquid replenishing system according to claim 7 , wherein the injecting portion is inserted downward into the receiving portion in a vertical direction.

15. The liquid replenishing system according to claim 7 , wherein the injecting portion is inserted downward into the receiving portion diagonally with respect to a vertical direction.

16. The liquid replenishing system according to claim 15 , wherein the receiving portion includes a region, which is inclined in the inserting direction of the injecting portion, in a region on the inner wall facing the opening.

17. The liquid replenishing system according to claim 7 , wherein the receiving portion includes a protrusion, which protrudes toward a region facing the opening, on the inner wall on a side more distant from the receiving port than the region facing the opening.

18. The liquid replenishing bottle according to claim 1 , wherein the inserting direction is vertical in a direction of gravity.

19. The liquid replenishing bottle according to claim 1 , wherein the inserting direction is oblique downward relative to a direction that is vertical in a direction of gravity.

20. The liquid replenishing bottle according to claim 1 , wherein the receiving portion is disposed on an end side of the liquid storage portion and protrudes from the liquid storage portion.

21. The liquid replenishing bottle according to claim 1 , wherein when the injecting portion is inserted into the receiving portion, there is a gap between (1) a part of an outer wall of the injecting portion and (2) the inner wall of the receiving portion.

22. The liquid replenishing bottle according to claim 1 , wherein the predetermined direction is a direction in which the recording liquid discharged from the opening contacts with the inner wall of the receiving portion.
