Disclosed is a method for suppressing adhesion of a liquid to the plug member. A disclosed liquid storage container has a storage chamber for storing a liquid, a supply port having a hollow cylindrical portion protruding from the storage chamber and being capable of supplying the liquid to the storage chamber, and a plug member detachably attached to the supply port. The plug member has a plug portion inserted into the hollow cylindrical portion to plug the supply port. On the plug portion, a first water repellent film having water repellency is formed on an exposed surface exposed at least to the inside of the hollow cylindrical portion in a portion inserted into the storage chamber.

Liquid storage container and liquid discharge apparatus

Provide is a liquid storage bottle capable of discharging liquid while preventing the liquid stored therein from remaining. The liquid storage bottle has a bottle body and a nozzle for pouring out the liquid stored in the bottle body, and inside the nozzle, a first fluid passage and a second fluid passages each of which opens to an outside on a tip end side of the nozzle and parallel to each other, and a communication passage which opens to an inside of the bottle body on a base end side of the nozzle and communicates with both the first and second fluid passages, are formed, and an inner circumferential surface of the communication passage is inclined inwardly toward the first and second fluid passages.

Liquid storage bottle and liquid replenishing system

To provide a liquid storage container equipped with a plug member that can prevent leakage of a liquid from the liquid storage container and can be opened without causing scatter of the liquid, and a liquid ejection apparatus equipped with the liquid storage container. For the purpose, at least one of a connection part of the convex part with the cover part and an apical part of the convex part most apart from the connection part is provided offset from the centroid of the cover part, seen from a direction orthogonal to an opening surface of a supply port in a state that the plug member is mounted on a supply port of the liquid storage container.

An ink cartridge includes an ink chamber that stores ink. A protruding chamber protrudes upward from the ink chamber in a gravitational direction when the ink cartridge is used. A swing body has a float and a detection portion, and a detection chamber in which the detection portion moves and with which an amount of ink stored in the ink chamber is detected in accordance with a position of the detection portion. In the ink cartridge, a pivot center of the swing body that pivotally moves is disposed inside the protruding chamber.

A liquid container unit includes: a liquid container including: a plurality of liquid storage portions; and a plurality of injection ports which are provided to the respective plurality of liquid storage portions, and are configured to enable injection of liquid into the plurality of liquid storage portions; and an injection port cover which is provided to the liquid container so as to be rotatable and is configured to cover the plurality of injection ports so as to be openable and closable, the injection port cover including a plurality of stopper members configured to close the plurality of injection ports when the injection port cover is closed.

Liquid container unit and recording apparatus

There are provided a liquid ejection apparatus with low costs, a liquid container, and a manufacturing method thereof. To this end, a rocking body is assembled to the liquid container to suppress the drop thereof by melting and swaging of a support shaft.

Liquid ejection apparatus, liquid container, and manufacturing method thereof

There are provided a liquid container including a plug member which prevents leakage of a liquid from the liquid container and can be opened without scattering the liquid and a liquid ejection apparatus including the liquid container. For that purpose, a projecting portion in the plug member is provided below a center part of the plug member in a gravity direction in an attitude at the time of use of the liquid ejection apparatus.

Liquid container and liquid ejection apparatus

A liquid supplying mechanism includes: a tank including a liquid storage section configured to store a liquid, and a liquid injection port configured to inject the liquid into the liquid storage section; and a bottle configured to replenish the liquid into the tank. The bottle includes: a bottle section configured to store the liquid; and a protruding section, which protrudes from the bottle section, and is insertable into the liquid injection port so as to inject, into the liquid storage section, the liquid stored in the bottle section. The liquid injection port includes: a protruding section insertion portion into which the protruding section of the bottle is insertable; and a protruding section fixing portion, which is engageable with the protruding section of the bottle, to thereby be capable of fixing the bottle to the tank.

Liquid supplying mechanism, and liquid ejection apparatus

An object is to provide a liquid ejecting apparatus that enables a liquid storage container to be properly and easily refilled with a liquid from a liquid refilling container without causing color mixture in the liquid storage container. The liquid ejecting apparatus includes liquid storage containers each configured to feed the liquid to a liquid ejecting portion and liquid refilling containers each configured to refill the liquid storage container with the liquid. A first fitting unit is provided around a liquid injection port in each of the liquid storage containers. A second fitting unit is provided around a liquid pour-out port in each of the liquid refilling containers. The second fitting unit is fitted to the first fitting unit to enable the liquid to be delivered from the liquid pour-out port to the liquid injection port.
