A liquid container includes: a bag having flexibility configured to store liquid inside; a liquid outlet member mounted on one end of the bag and having a liquid outlet section to discharge the liquid to a liquid ejecting apparatus; a gas absorption unit movably disposed in the bag and having (i) a space holding member that forms an internal space of the gas absorption unit, and (ii) a gas transmission film that defines an inside of the internal space and an outside with the internal space decompressed to a pressure lower than an atmospheric pressure; and a plurality of liquid outlet pipes coupled to the liquid outlet section and disposed in the bag, the plurality of liquid outlet pipes having an inlet, which are configured to allow the liquid introduced from the inlet to flow to the liquid outlet section. Lengths of the plurality of liquid outlet pipes are different.

Liquid container

A liquid container includes: a bag having flexibility configured to store liquid inside; a liquid outlet member attached to one end of the bag and having a liquid outlet section to discharge the liquid to a liquid ejecting apparatus; a spacer member disposed in the bag, the spacer member including a filter chamber in which a filter that filters the liquid is disposed; and a liquid outlet pipe disposed in the bag and coupled to the filter chamber and the liquid outlet member, the liquid outlet pipe being configured to flow the liquid filtered by the filter to the liquid outlet section. The liquid outlet pipe has flexibility.

Provided is a liquid container configured to be detachably attached to a printer body. The liquid container includes a liquid containing portion, a supplying passage member, and an adapter. The liquid containing portion is a portion for containing liquid. The supplying passage member has a supplying passage in liquid communication with the liquid containing portion, the liquid contained in the liquid containing portion being supplied toward the printer body through the supplying passage. The adapter is mounted on the supplying passage member and configured to couple the supplying passage to the printer body. The adapter and the supplying passage member are joined by snap fitting.

A gas-absorbing apparatus disposed in a liquid housing that has a supply port portion for supplying the liquid to an external, includes a space retaining member that forms an internal space of the gas-absorbing apparatus, and a gas-permeable film that partitions off an inside of the internal space from an outside in a state where the internal space is depressurized to a pressure lower than atmospheric pressure, the gas-absorbing apparatus being separate from the supply port portion.

A liquid housing container includes a suppressing portion at one end portion of a first surface-portion film and one end portion of a second surface-portion film, and at another end portion of the first surface-portion film and another end portion of the second surface-portion film. The suppressing portion suppresses spreading of a gap between the one end portion of the first surface-portion film and the one end portion of the second surface-portion film, and spreading of a gap between the other end portion of the first surface-portion film and the other end portion of the second surface-portion film.

Liquid housing container, liquid housing apparatus, and liquid ejecting apparatus

The liquid container includes: a container main body including a containment chamber containing a liquid and has some walls including a front-end wall, a rear-end wall, and an upper-surface wall; a liquid outlet connected to a liquid-consuming device to flow out the liquid from the containment chamber to the liquid-consuming device; a liquid inlet on the upper-surface wall at a position closer to the rear-end wall and accepts injection of the liquid from outside of the container main body into the containment chamber; and a visual recognition portion that is provided on the rear-end wall and is see-through so that a position of a liquid surface of the liquid in the containment chamber is recognizable. The rear-end wall has scale marks as indexes of an amount of the liquid in the containment chamber on an outer wall surface and an inner wall surface.

There is provided with a cartridge comprising a liquid supply portion; a contact portion that is located on a +Z-axis direction side of the liquid supply portion and that is arranged to contact with an electrical connecting element; and a positioning structure that is located between the liquid supply portion and the contact portion in a Z-axis direction. The liquid supply portion is configured to receive a first external force in a &#x2212;Y-axis direction from the liquid introducing structure when the liquid supply portion is connected with the liquid introducing structure. The contact portion is configured to receive a second external force in a direction including a &#x2212;Y-axis direction component from the electrical connecting element when the contact portion comes into contact with the electrical connecting element. This configuration suppresses position misalignment of the cartridge or a connector to a mounting structure.

Cartridge and connector

Provided is a technique that makes it possible to mitigate impact acting on a liquid container. The liquid container includes a liquid storage portion that is surrounded by a plurality of wall portions, and contains liquid therein, and a plurality of contact portions that are provided on a first wall portion among the plurality of wall portions, and are in contact with terminals on-the-apparatus-side provided in a liquid consumption apparatus. The contact portions are provided at a position close to a first edge side, at least some of the plurality of contact portions form at least one column arranged along the first edge side, the liquid container includes protruding portions outward of outer contact portions, and the protruding portions are provided between an end portion the first edge side of the outer contact portions and the first edge side in a direction from the first edge side toward the column.

A liquid supply unit configured to supply a liquid to a liquid inlet of a liquid jet apparatus. The liquid supply unit includes a liquid housing part configured to house a liquid, a liquid outlet configured to draw the liquid from inside the liquid housing part to outside the liquid housing part, and a filter provided upstream of the liquid outlet in a channel of the liquid that is drawn from inside the liquid housing part to outside the liquid housing part via the liquid outlet. The filter includes a first filter and a second filter that are constituted by a plurality of fibers laminated in a flow direction of the liquid. The first filter is provided upstream of the second filter in the channel of the liquid, and the first filter and the second filter differ in coarseness.
