Abstract

A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged and a coupling portion in which a male thread portion is arranged on the outside; and a cover portion including a female thread portion on the inside and configured to be attachable to the discharge port member, the female thread portion configured to be screwed to the male thread portion, in which the male thread portion is discontinuous in the coupling portion.

Claims (40)

1. An ink storage bottle for replenishing a liquid tank of a liquid ejecting apparatus with ink, the liquid ejecting apparatus configured to eject the liquid, comprising:

a discharge port portion including a discharge port through which ink stored in a storage portion can be discharged; and

a cover portion configured to be attachable and detachable to the discharge port portion, wherein

the discharge port portion viewed from a direction in which the cover portion is attached has continuously a first circular arc, a linear portion, and a second circular arc.

2. The ink storage bottle according to claim 1 , wherein the cover portion is configured to be attached to the discharge port portion by screwing of a male thread portion of the discharge port portion to a female thread portion of the cover portion.

3. The ink storage bottle according to claim 2 , wherein the male thread portion is discontinuous in that threads thereof are not continuously formed over the entire outside periphery of the discharge port member.

4. The ink storage bottle according to claim 3 , wherein in a state where the cover portion is attached to the discharge port portion, a space is provided between a portion of the discharge port portion in which the male thread portion is discontinuous and the cover portion.

5. The ink storage bottle according to claim 2 , wherein the male thread portions form one helical shape as a whole and are configured such that the male threads are screwed to the female thread in the cap.

6. The ink storage bottle according to claim 1 , wherein a recess portion is provided in the circular arcs.

7. The ink storage bottle according to claim 6 , wherein

the recess portion is configured to engage with a protruding portion provided in a socket provided to surround the outside of the liquid tank.

8. The ink storage bottle according to claim 7 , wherein the recess portion is configured to engage with the protruding portion in replenishment of the liquid tank with the ink.

9. The ink storage bottle according to claim 7 , wherein

the liquid ejecting apparatus includes a plurality of the liquid tanks, and the sockets of the respective liquid tanks vary in shape, and

the recess portion is capable of engaging only with the protruding portion formed in the socket of one of the plurality of liquid tanks and not to engage with the protruding portions formed in the sockets of the other liquid tanks.

10. The ink storage bottle according to claim 7 , wherein

the discharge port portion includes a plurality of the recess portions, and is configured such that at least one of the recess portions engages with the protruding portion and the other recess portions do not engage with the protruding portion.

11. The ink storage bottle according to claim 10 , wherein the plurality of recess portions are rotationally symmetric by 180° about a center of a circle corresponding to the first circular arc and the second circular arc.

12. The ink storage bottle according to claim 7 , wherein

the socket of the liquid tank includes a plurality of the protruding portions,

the discharge port portion includes a plurality of the recess portions, and

the plurality of the recess portions are configured to engage with the plurality of protruding portions, respectively.

13. The ink storage bottle according to claim 1 , wherein a protrusion is provided in a position where the cover portion faces the discharge port.

14. The ink storage bottle according to claim 1 , wherein a distance between center of the linear portion and a center of a circular arc in a circle corresponding to the first circular arc and the second circular arc is 0.5 mm or more, the circular arc corresponding to the linear portion.

15. The ink storage bottle according to claim 1 , wherein a proportion of the recess portion to a circle corresponding to the first circular arc and the second circular arc is 10% or more and 90% or less.

16. The ink storage bottle according to claim 1 , wherein a proportion of the recess portion to a circle corresponding to the first circular arc and the second circular arc is 20% or more and 70% or less.

17. The ink storage bottle according to claim 1 , further comprising a sealing portion formed of a contact portion between the cover portion and the discharge port portion.

18. The ink storage bottle according to claim 1 , wherein the first circular arc has a first recess portion and the second circular arc has a second recess portion viewed from the direction in which the cover portion is attached.

19. An ink storage bottle for replenishing ink to a liquid tank of a liquid ejecting apparatus comprising:

a discharge port portion including a discharge port through which ink stored in a storage portion can be discharged; and

a cover portion configured to be attachable and detachable to the discharge port portion, wherein

the discharge port portion viewed from a direction in which the cover portion is attached has continuously a first circular arc, a linear portion, and a second circular arc,

wherein the cover portion is configured to be attached to the discharge port portion by screwing of a male thread portion of the discharge port portion to a female thread portion of the cover portion, and the male thread portion is discontinuous in the coupling portion in that threads thereof are not continuously formed over the entire outside periphery of the discharge port member and the male thread portions form one helical shape as a whole and are configured such that the male threads are screwed to the female thread in the ca p, and

wherein the recess portion is provided in the circular arcs.

20. An ink storage bottle for replenishing a liquid tank of a liquid ejecting apparatus with ink, the liquid ejecting apparatus configured to eject the liquid, comprising:

a discharge port portion including a discharge port through which ink stored in a storage portion can be discharged; and

a cover portion configured to be attachable and detachable to the discharge port portion, wherein

the discharge port portion viewed from a direction in which the cover portion is attached has two linear portions and two circular arcs,

wherein each of the circular arcs has a recess portion recess from a circle corresponding to the circular arcs,

wherein the recess portions are rotationally symmetric by 180° about a center of the circle.
