Various defects that occur when a water-repellent or defoaming layer is formed on a contact portion of a liquid container are reduced. A method for manufacturing a liquid container for containing a liquid includes: (a) preparing a pre-formation liquid container in which a surface layer has not been formed; (b) bringing an aqueous solution obtained by adding water to one of a defoaming agent and a water-repellent agent into contact with a surface of a contact portion with which the liquid is brought into contact, of the pre-formation liquid container; and (c) drying, after the step (b), the contact portion to form the surface layer that is formed of one of the defoaming agent and the water-repellent agent on a surface of the contact portion.

Method for manufacturing liquid container, and liquid container

A liquid jet apparatus comprises a liquid jet head, a carriage carrying the liquid jet head in a side-to-side direction, a liquid flow channel, and a liquid container in fluid communication with the liquid jet head through the liquid flow channel. The liquid container includes a liquid containing chamber arranged along a front/back direction orthogonal to the side-to-side direction; a liquid outlet port, from which the liquid contained in the liquid containing chamber flows to the liquid flow channel; and a liquid inlet port, through which the liquid is injected into the liquid containing chamber. The liquid inlet port has an end surface that does not face in a vertical direction relative to a normal posture of the apparatus.

Liquid container, liquid consuming apparatus, liquid supply system and liquid container unit

A liquid ejecting apparatus includes a liquid ejecting head which ejects liquid from a nozzle that is disposed on a nozzle surface, and an absorption member which is able to contact the nozzle surface, in which it is possible to perform a first contact operation which causes the absorption member to contact the nozzle surface at a position which corresponds to a nozzle region that includes an opening region of the nozzle, and a second contact operation which causes the absorption member to contact the nozzle surface at a position which corresponds to a non-nozzle region that is a region outside of the nozzle region.

Liquid ejecting apparatus and cleaning device

A liquid storage container includes a liquid storage section configured to store a liquid, a liquid injection section connected to the liquid storage section and configured to inject the liquid into the liquid storage section, an air chamber communicated with air, an air introduction section communicated to the air chamber and configured to introduce the air to the air chamber, a communicating passage through which the liquid storage section and the air chamber are communicated to each other, a liquid injection port defined as an intersection at which the liquid injection section and the liquid storage section intersect each other, and a connecting port defined between the liquid storage section and the communicating passage and located above the liquid injection port in a posture where the liquid injection port is oriented upward in a direction intersecting with a horizontal direction.

Liquid storage container and liquid jet apparatus

Provided is a liquid storing body for preventing a liquid containing a sedimentous component with a predetermined concentration or more from being supplied to a liquid jetting apparatus. An ink tank is provided with an ink storing part in which an opening provided on a side surface of a case is sealed with a film. An ink injection port is formed in an upper portion wall of the case. A plug member is provided with a sealing part that can seal the ink injection port, an operation part that is inserted in an ink reservoir chamber via the ink injection port, and a stirring portion provided at the lower end of the operation part. Ink in the ink storing part can be stirred by a user moving the plug member up and down with their hand.

Liquid storing body including a stirring member

A liquid container includes a container portion configured to contain ink; an air chamber configured to contain the air that is introduced into the container portion; a first air introducing path configured to introduce the outside air into the air chamber; and a second air introducing path configured to introduce the air contained in the air chamber into the container portion. The first introducing port is located vertically above a liquid level in the air chamber of the ink flowing from the container portion into the air chamber, in a first attitude that the container portion and the air chamber are aligned in a direction intersecting with a vertical direction and that a first introducing port of the first air introducing path is located vertically above a delivery port of the second air introducing path.

Liquid container

A case includes a main receptacle body that accommodates an ink accommodating body which accommodates ink. A first tube support portion and second to fourth tube support portions that guide connection tubes that are connected to the ink accommodating bodies, respectively, are provided on an internal surface of the main receptacle body.

Liquid-accommodating-body accommodating receptacle, liquid supply apparatus, and liquid ejecting apparatus

A liquid container includes an ink chamber containing an ink to be supplied via a tube to a liquid ejecting head consuming the ink; an outlet port from which the ink contained in the ink chamber flows to the tube side; an injection port through which the ink can be injected into the ink chamber; and an air intake port taking air into the ink chamber from a further vertically upper position than a liquid level of the ink when the ink is contained in the ink chamber. If the ink equal to 5% of containing capacity containable in the ink chamber flows from the outlet port, the liquid container has an area where a fluctuation range of the liquid level of the ink inside the ink chamber becomes 5% or less of the cubic root of the containing capacity.

A liquid storage container includes a liquid storage section configured to store a liquid, a liquid injection section configured to inject the liquid into the liquid storage section, a liquid injection port defined as an intersection at which the liquid injection section and the liquid storage section intersect each other, an air chamber communicated with air, an air introduction path communicated to the air chamber and configured to introduce the air to the air chamber, a communicating passage through which the liquid storage section and the air chamber are communicated to each other, a first connecting port, which is a connecting port between the air introduction path and the air chamber, being located below a position that is lowered by a first distance from an upper end of the air chamber and located above a position that is raised by a second distance from a lower end of the air chamber in a posture where a liquid injection port is oriented upward in the intersecting direction, and a second connecting port, which is a connecting port between the communicating passage and the air chamber, in the intersecting direction in the posture, where the first distance is defined as a length of the first connecting port in an intersecting direction intersecting with a horizontal direction in the posture and the second distance is defined as a length of the second connecting port in the intersecting direction in the posture.

A liquid ejecting apparatus capable of supplying liquid stably and continuously through a liquid supplying tube which performs a following deformation in accordance with a movement of a carriage embedded with a liquid ejecting head, while achieving compactness of a main body of the apparatus. The liquid ejecting apparatus includes a liquid ejecting head capable of ejecting ink onto a sheet; a carriage capable of reciprocating inside a main body case in a state of being embedded with the liquid ejecting head and an adaptor capable of supplying ink to the liquid ejecting head; and an ink supplying tube which performs a following deformation in the main body case in accordance with the reciprocation of the carriage in a state of being led out to be able to supply ink from an ink tank at an upstream side, disposed outside a movement range of the carriage, to the adaptor at a downstream side.
