Ink pack

A liquid storage bag includes a bag configured to store a liquid and a feeder that feeds the liquid in the bag to an external component. The bag is formed of a film. The film includes a first base layer, a second base layer, and a first black layer located between the first base layer and the second base layer. The first black layer is formed of a black colorant filling a layer surface of the second base layer.

Liquid storage bag

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.

Liquid container

A cartridge includes a concave portion. The concave portion has an opening, first and second side walls, and a bottom wall, and the bottom wall has a tilted surface tilted. The tilted surface is provided with a cartridge side terminal group. The first side wall is provided with a first restriction portion which restricts movements in a +Z axis direction and a +X axis direction of an apparatus side terminal unit, and the second side wall is provided with a second restriction portion which restricts movements in the +Z axis direction and a −X axis direction of an apparatus side terminal unit.

A cartridge includes a concave portion. The concave portion has an opening, first and second side walls, and a bottom wall, and the bottom wall has a tilted surface tilted. The tilted surface is provided with a cartridge side terminal group. The first side wall is provided with a first restriction portion which restricts movements in a +Z axis direction and a +X axis direction of an apparatus side terminal unit, and the second side wall is provided with a second restriction portion which restricts movements in the +Z axis direction and a &#x2212;X axis direction of an apparatus side terminal unit.

A technique for suppressing a contact failure between a contact portion and an apparatus-side terminal in a cartridge including a case, a liquid supply port, and a contact portion that is disposed at a corner where a front surface and a top surface intersect each other and is in contact with an apparatus-side terminal of a liquid ejecting apparatus, the liquid supply port is disposed at the center of the case in a width direction in which a first side surface and a second side surface oppose each other, and the contact portion is disposed at a position shifted to one side of the first side surface side and the second side surface side in the width direction.

Cartridge and liquid ejecting apparatus

An exterior body for storing a liquid storage body including a first main film, a second main film, and a first side film that define an interior space containing a liquid, the first side film having a gusset portion having a fold, the exterior body including an outer shell that forms a storage space storing the liquid storage body, and a pressing portion that is provided in the outer shell, that presses the first side film, and that bend the gusset portion inward.

Ink cartridge

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

A detachable body for a printing apparatus enables positioning a board for electrical connection to a printing apparatus, while also reducing manufacturing cost. The detachable body for a printing apparatus includes a case that is mounted to and detached from a printing apparatus that performs printing on a sheet, and a board that is attached to an attachment surface that is a surface of the case, and that is electrically connected to the printing apparatus by coming into contact with detachable body-side contacts provided on the printing apparatus when the case is mounted to the printing apparatus. The attachment surface of the case is provided with an attaching portion to which the board is attached. The attaching portion surrounds the board and positions the board in a direction along the attachment surface of the case by coming into contact with peripheral edges of the board.

Detachable body for printing apparatus

A liquid ejecting apparatus includes a liquid ejector that ejects a liquid, a liquid supply flow path that connects a liquid supply source and the liquid ejector, a plurality of branch flow paths provided in the liquid supply flow path, filters that are disposed separately in each of the branch flow paths, and a flow path opening/closing mechanism that opens and closes the branch flow paths.

Ink storage attachment

A liquid holding container having an ink pack constituted by a sheet member, capable of housing ink inside, a flow path member extending through the sheet member, between the outside and inside of the ink pack, and having a flow path capable of delivering ink from the inside to the outside of the ink pack, and a filter provided in the flow path member inside the ink pack. The flow path member and the sheet member are joined, and the flow path extends further to the inside of the ink pack than the end part which is the junction part at the position of the sheet member joined with the flow path member. At the flow path member, the filter is provided at a site further to the inside of the ink pack than the junction part.
