    摘要： A sealing member is applied to the surface of a liquid storage container having a liquid supply port provided so as to be open to a concave space formed on the surface with a gap between the applied sealing member and the liquid supply ports so as to seal the concave space. The liquid supply port has a profile adapted to be inserted into and connected to a connecting portion for supplying liquid to the liquid supply port. A cut score section is formed on the sealing member as including a center point located at the position on the extension from the front end of the liquid supply port in the direction of connecting the liquid supply port to the connecting portion and the cut score section is torn as it is pressed by the connecting portion moving toward the liquid supply port.

    摘要： A liquid storage bottle includes a nozzle which has an inlet through which a liquid is injected, a cylindrical cap which is mountable on the nozzle to open or close the inlet, a slit valve which is provided in the inlet and includes a plurality of slits intersecting each other, and a sealing unit which seals the inlet when the cap is mounted on the nozzle. The cap includes a protrusion which protrudes from a surface facing the inlet toward the slit valve when the cap is mounted on the nozzle, and a tip portion of the protrusion faces the slit valve at a position separated in a radial direction of the nozzle from an intersection of the plurality of slits in a state where the inlet is sealed by the sealing unit.

    摘要： Provided is a liquid ejecting apparatus comprising: a cartridge capable of ejecting a liquid stored therein; a flow channel through which the cartridge and a liquid tank capable of supplying the liquid to the cartridge are in fluid communication with each other; a closing unit capable of closing the flow channel; and a movable member configured to be operated before the cartridge and the flow channel are uncoupled. The closing unit comprises a closing member, and closes the flow channel with the closing member moved with movement of the movable member. The liquid ejecting apparatus further comprises a carriage capable of carrying the cartridge and moving during liquid ejection of the cartridge. The movable member is a covering member provided to the carriage and configured to cover the cartridge, and in replacement of the cartridge, the movable member is removed from covering the cartridge to allow access to the cartridge.

    摘要： There is provided a liquid storage container capable of keeping a negative pressure therein more reliably. An ink cartridge includes a negative pressure generation unit configured to generate a negative pressure in an ink storage chamber and a filter attached to an atmosphere communication channel opening and allowing air to pass from the outside to the inside of the liquid storage chamber depending on the negative pressure in the ink storage chamber. The ink cartridge has a capillary groove configured to supply ink from a portion in which ink is stored in the ink storage chamber to the filter.
