An ink refill container includes a container main body including an ink storage chamber, an ink outlet-forming portion provided on an end portion of the container main body forming an ink outlet that allows the ink to flow out from the ink storage chamber, and a valve provided in the ink outlet-forming portion configured to openably seal the ink outlet, in which the ink outlet-forming portion includes a positioning portion on an outer side of the ink outlet-forming portion. in which the positioning portion is closer to the container main body than the valve is to the container main body in a central axis direction of the ink outlet, and in which the positioning portion partially abuts against an ink tank when the valve is opened for refilling the ink to the ink tank, to thereby position the valve relative to the ink tank.

Provided is a storage device including a container that includes an accommodation chamber accommodating fluid or powder, a flexible film that is bonded to the container and covers an opening portion of the accommodation chamber, and a tank holder to which the container having the film bonded thereto is fixed by a screw, in which the screw penetrates the film and fixes the container to the tank holder, and a part of a bonded portion between the film and the container surrounds a portion of the film through which the screw penetrates.

A device includes a fluid channel connecting a pair of ports and an attachment feature to attach the device at a dummy cartridge; wherein the pair of ports is dimensioned to mate with fluid feed ports of a printer when the device is attached to the dummy cartridge and the dummy cartridge is inserted in the printer.

In an image-recording device, a cartridge has a first chamber and an outlet. A mount body includes a tank, first and second sensors. The tank has an inlet, and a second chamber. The liquid in the first chamber flows into the second chamber via the outlet and the inlet. The first sensor outputs a first signal when a level of the liquid in the second chamber is higher than a first position, and outputs a second signal when the level is lower than the first position. The second sensor outputs a third signal when the level is higher than a second position higher than the first position, and outputs the fourth signal when the level is lower than the second position. A controller controls a notification device to issue a notification if a condition based on the first and second signals is satisfied.

When a known lid member was merely applied to a bottle that contains ink, there was room for improvement in terms of the operation of the lid member and the way how to bring attention to the handling thereof. A bottle set is provided that includes: a bottle that includes an ink container that contains ink, and an outflow port through which the ink in the ink container flows out to the outside; and a lid member that is configured to attach to and detach from the bottle, and is configured to cover the outflow port in a state of being attached to the bottle. The lid member includes a colored portion that has optical transparency and is colored with a color corresponding to a type of the ink contained in the ink container in at least a portion of the lid member.

Management system for the ink in a printing machine, comprising: one or more tanks (2), each of which is equipped with hydraulic connections (21) for quick coupling and an inner layer of insulation; a docking station (3), arranged to be placed in a printing machine, which comprises hydraulic connections (31) for quick coupling, intended to be connected to the hydraulic connections (21) of one or more tanks (2); motor means (4), associated with the docking station (3) and arranged to transfer a tank (2) between a standby position and an operating position within the docking station, and to produce the coupling of the hydraulic connections (21,31).

A cartridge includes a liquid containing portion and a liquid supply portion that includes a cartridge side valve mechanism, the cartridge side valve mechanism includes a cartridge side valve seat in which a cartridge side valve hole is formed, a cartridge side valve body that stops the cartridge side valve hole and has a tip surface positioned adjacent to the supply opening, and a cartridge side urging member that urges the cartridge side valve body in a direction toward the cartridge side valve seat, and the cartridge side valve body has a protrusion that protrudes from the tip surface and pushes the device side valve body to open the device side valve body.

A cartridge detachably mounted in a liquid ejecting apparatus including a liquid introduction portion includes: a liquid supply portion having a supply portion flow path; a valve seat having a valve seat insertion port; a valve body upstream of the valve seat; a biasing member biasing the valve body toward the valve seat; a cap located downstream of the valve seat; and a liquid absorbing material in contact with the cap, in which the cap has a first surface facing the valve seat, a second surface facing the first surface and contacting the liquid absorbing material, a cap insertion port formed over the first and second surfaces, into which the liquid introduction portion is inserted, a groove formed in the first surface and facing the valve seat, and a hole formed over the first and second surfaces and coupled to the groove, and liquid absorbing material is in the hole.

A recording apparatus includes an ink tank, a carriage, a recording head mounted on the carriage, a carriage control unit, and a supply tube connected to the recording head and the ink tank and including a bent portion that moves with carriage movement. The carriage control unit moves the carriage in predetermined directions to record on a recording medium. Assuming that, of an acceleration/deceleration area of a carriage moving area, an area in which pressure changes to decrease negative pressure in the recording head is a first area, and an area in which the pressure changes to increase the negative pressure in the recording head is a second area, the carriage control unit moves the carriage so that an absolute value of acceleration or deceleration of the carriage in the first area is less than an absolute value of acceleration or deceleration of the carriage in the second area.

A cartridge includes: a liquid accommodating portion; a liquid supply portion having a central axis and a supply portion flow path which communicates with the liquid accommodating portion; and a valve mechanism arranged in supply portion flow path, wherein the valve mechanism has a valve seat having an insertion port into which liquid introduction portion is inserted, a valve body having a closing surface which abuts on the valve seat to close the insertion port, and a biasing member biasing valve body toward the valve seat, the valve mechanism is opened by the valve body being pushed by the liquid introduction portion, and the closing surface has a flat surface portion, and an inclined surface portion formed around the flat surface portion and inclined toward an edge of the closing surface, and at least a part of the inclined surface portion faces the introduction portion flow path in mounted state.
