  • Publication number: 20150097902
    Abstract: A liquid housing body recycling method is provided for a liquid housing body that includes a liquid housing unit that is configured to house liquid, a supply member with a supply port that is configured to be connected to a liquid supply tube of a liquid consuming device, and a filter through which the liquid is configured to pass, with the liquid inside the liquid housing unit being supplied to the liquid consuming device via the supply port by passing through the filter. The liquid housing body recycling method includes forming an opening part on the liquid housing unit at a position outside an area facing opposite the filter on the liquid housing unit, injecting the liquid from the opening part of the liquid housing unit on which the opening part has been formed, and sealing the opening part.

  • Publication number: 20150077484
    Abstract: A liquid container that can be mounted to a mounting portion in a stable state is provided. An ink cartridge includes: a first surface that has formed therein a liquid supply opening through which the ink can flow from the ink chamber to the outside, and is on the side in the direction of insertion into the mounting portion; a second surface that opposes the first surface; a third surface that intersects the first surface and the second surface; a fourth surface that opposes the third surface; a fifth surface that intersects the first surface, the second surface, and the third surface; and a sixth surface that opposes the fifth surface. Protrusion portions are respectively provided on the fifth surface side and the sixth surface side of at least one of the third surface and the fourth surface, and the protrusion portions come into contact with the mounting portion.

  • Publication number: 20150077485
    Abstract: A liquid container can be smoothly mounted to a mounting portion, and the liquid container is reliably locked when mounting is complete. The liquid container includes: a first surface that is on a side in a direction of insertion (+Y direction); a second surface that opposes the first surface; a third surface that intersects the first surface and the second surface and has formed therein a groove portion that can engage with a lever member; a fourth surface that opposes the third surface; and lower protruding wall portions that are provided on at least one of the third surface and the fourth surface, and are positioned by guide surfaces of lower guide ribs of the mounting portion when the ink cartridge is locked by engagement of the groove portion with the lever member due to the ink cartridge moving in the direction of insertion into the mounting portion.

  • Publication number: 20150077483
    Abstract: A liquid containing body includes a liquid containing vessel, and a casing member. The liquid containing vessel contains a liquid, and includes a supply member with a liquid supply opening that supplies the liquid to a liquid consumption apparatus. The casing member supports at least the supply member. The supply member has a cylindrical flow path section that defines the liquid supply opening. The casing member has a through hole forming section with a through hole. The cylindrical flow path section is insertable in the through hole. The casing member further has an engaging section that engages with the supply member to regulate movement of the cylindrical flow path section in an opposite direction to an insertion direction while the cylindrical flow path section is rotated with the insertion direction as an axial line in a state where the cylindrical flow path section is inserted in the through hole.

  • Publication number: 20140340453
    Abstract: A cartridge comprises: a printing material container; a printing material supplier that supplies a printing material contained in the printing material container to a printing device; a first surface and a second surface that are opposed to each other; a third surface that intersects with the first surface and the second surface; a fourth surface that is opposed to the third surface; a cartridge-side engagement structure that is provided on the third surface at a position closer to the first surface than the second surface and is configured to be engaged with a device-side engagement structure of the printing device; and contact portions that are provided in an area where both an end of the first surface proximate to the fourth surface and an end of the fourth surface proximate to the first surface are located and are configured to be in contact with the printing device. A contact surface defined by the contact portions is inclined to the fourth surface.
