There is provided a liquid pack including: a pouch configured to store a liquid therein; and a spout configured to be connectable to a part at one end in a first direction of the pouch, and having a channel in which the liquid passes. The pouch has: a liquid storing chamber configured to store the liquid therein and communicating with the channel of the spout, a sealing part configured to seal surrounding of the liquid storing chamber, and a liquid-non-storing chamber which is positioned to be separated with respect to the spout by the liquid storing chamber and the sealing part, and in which the liquid is not stored.

A tank set includes: tanks arranged in a predetermined direction, each of the tanks being composed of a casing including: a liquid storage chamber defined by mutually opposing two surfaces and configured to store liquid; an inlet provided to inject the liquid into the liquid storage chamber; and a liquid outflow port through which the liquid flows out from the liquid storage chamber to a liquid-consuming unit. Each of the two surfaces extends in a direction intersecting the predetermined direction, and is at least partially composed of a film.

A printable liquid supply cartridge includes a printable liquid reservoir extending between a first side and a second side, and between a front end and a rear end. The front end includes a printable liquid outlet to receive a first fluid pen and a gas inlet, above the printable liquid outlet, to receive a second fluid pen. The front end also includes an interface support at the first side, the support having an I2C data interface that includes electrical connection pads exposed on an interior side of the support to face from the first side towards the second side, the electrical connection pads being arranged vertically and to make contact with the printer data interface at least partially inserted into the second portion.

A print head can suppress contamination due to ink at the time of being mounted on a printing apparatus and/or after being detached from the printing apparatus. For this purpose, a positioning pin longer than a needle is provided in a joint unit of the print head, and the joint unit includes a shutter which closes an opening on a supply side and an opening on a collection side when the print head is detached.

A liquid storage container is configured to supply a liquid containing a precipitating component to a liquid ejecting apparatus, including: a partitioning member configured to divide a liquid storage chamber in a direction intersecting a direction of gravitational force; a plurality of liquid storage chambers divided by the partitioning member; and communication flow channel units provided to the plurality of liquid storage chambers, respectively, and configured to introduce the liquid in the liquid storage chambers and to supply the liquid to the liquid ejecting apparatus.

A system includes: a housing; a first tank; a second tank; a first reservoir configured to be connected to the first tank; a second reservoir configured to be connected to the second tank; and a liquid discharge head that ejects the liquid supplied from the first tank and the second tank. The housing includes: a front wall; a rear wall facing the front wall; and a housing side contact, the first reservoir and the second reservoir includes: a liquid flow hole; a first outer wall; and a second outer wall facing the first outer wall, the first tank includes a first flow pipe, and the second tank includes a second flow pipe. The system further includes a circuit board that is disposed on the second outer wall and has a reservoir side contact that contacts the housing side contact.

The present disclosure provides an inkjet assembly, an inkjet printing apparatus and an inkjet printing method for use in preparation of a display component. The inkjet assembly is for use in an inkjet printing apparatus, including a jet printing member having a first surface. A main inkjet channel, a liquid-phase channel in communication with the main inkjet channel, and a gas-phase channel in communication with the main inkjet channel are formed in the jet printing member. An axial direction of the liquid-phase channel intersects an axial direction of the main inkjet channel, and an axial direction of the gas-phase channel intersects the axial direction of the main inkjet channel. An end opening of the main inkjet channel is formed as a nozzle on the first surface.

A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged; a cover portion configured to be attachable to and detachable from the discharge port member and to be capable of opening and closing the discharge port; a liquid stop valve provided inside the discharge port member; and a protrusion provided inside the cover portion and configured to open the liquid stop valve in closing the cover portion. In the liquid storage container, the storage portion is sealable by at least one of a first sealing portion formed of a contact portion between the cover portion and the discharge port member and a second sealing portion formed of the liquid stop valve, and the first sealing portion and the second sealing portion are configured to be simultaneously unsealed.

An ink jet recording apparatus includes an ink composition, an ink encasement in which the ink composition is encased, a recording head that ejects the ink composition, and a carriage configured to move the recording head back and forth. The carriage carries the ink encasement, with the ink encasement integrated with the carriage. The ink encasement has an ink fill port that opens and shuts as a port through which the ink composition is loaded. The ink composition contains a disperse colorant, with the volume-average particle diameter of the disperse colorant being 105.0 nm or less.

In one example in accordance with the present disclosure, a refill container is described. The refill container includes a reservoir to house a volume of print compound and a chamber to house a pressurized fluid. A wall separates the reservoir from the chamber. A pressure release device of the refill container creates a fluid path between the chamber and the reservoir such that the pressurized fluid flows into the reservoir to mix with the volume of print compound. A trigger of the refill container activates the pressure release device.
