Abstract

A liquid accommodation body to be connected to a liquid ejection device for ejecting liquid, the liquid accommodation body including a container that has an inlet section with an inlet through which liquid is introduced and that contains the liquid; a cap that seals the inlet by covering the inlet section; and a lead out section that leads liquid to the liquid ejection device; wherein when the cap seals the inlet, the cap and the inlet section configure an atmospheric release path that enables the inlet to connect to atmosphere.

Claims (39)

1. A liquid accommodation body to be connected to a liquid ejection device for ejecting liquid, the liquid accommodation body comprising:

a container that has an inlet section with an inlet through which liquid is introduced and that contains the liquid;

a cap that seals the inlet by covering the inlet section; and

a lead out section that leads liquid to the liquid ejection device, wherein

when the cap seals the inlet, the cap and the inlet section form an atmospheric release path that connects the inlet to atmosphere.

2. The liquid accommodation body according to claim 1 , wherein

the atmospheric release path has a through passage that penetrates through the inlet section.

3. The liquid accommodation body according to claim 2 , wherein

the atmospheric release path has a gap between the inlet section and the cap.

4. The liquid accommodation body according to claim 1 further comprising:

an indication section that indicates a type of liquid that is introduced through the inlet, wherein

the indication section is located on the cap.

5. The liquid accommodation body according to claim 1 , wherein

the container further has an inclined surface inclining upward and a gripping section to be gripped by a user, wherein

the inlet section is located on the inclined surface and

the gripping section is located at the same height as the inlet section in the vertical direction.

6. The liquid accommodation body according to claim 1 , further comprising:

a cover that covers a part of the container, wherein

the container is configured with a transparent or translucent material and

a surface area of the container that is covered by the cover is smaller than a surface area of the container that is not covered by the cover.

7. The liquid accommodation body according to claim 6 , wherein

the container has a visual check section that enables a visual check of a liquid level of the liquid contained in the container,

the inlet section is located above the visual check section and is vertically aligned with the visual check section as the visual check section is viewed from the front,

the cover covers a part of the container so as to expose the visual check section, and

the cover has an inlet opening into which the inlet section is inserted.

8. The liquid accommodation body according to claim 6 , wherein

the container has a visual check section that enables a visual check of a liquid level of the liquid contained in the container,

the visual check section protrudes from a front surface of the container,

the cover covers a part of the container so as to expose the inlet, and

the cover has a viewing opening into which the visual check section is inserted.

9. The liquid accommodation body according to claim 8 , wherein

the inlet section is located above the visual check section and is vertically aligned with the visual check section as the visual check section is viewed from the front, and

the cover has an inlet opening into which the inlet section is inserted.

10. The liquid accommodation body according to claim 1 , wherein

the cap further includes

an attachment member that is attached to the inlet section,

a lid member that is attached to the attachment member and that opens and closes with respect to the inlet section, and

a pressing member that presses the lid member so as to open the lid member, wherein

the attachment member has the holding portion that holds the lid member in a closed position by contacting the lid member.
