  • Patent number: 11305549
    Abstract: A container stores a fluid for use in an ink jet printer. The container includes: a casing that defines a storage space for storing the fluid, and has an opening communicating with the storage space; a film that covers the opening and seals the storage space; and a film attachment section that fixes the film to the casing. The casing includes a first surface that surrounds a periphery of the opening, and faces the film, and a second surface that surrounds the opening at a position farther from the opening than the first surface, has an angle intersecting the first surface, and faces the film, and the film attachment section is provided on the second surface.
    Type: Grant

  • Patent number: 10173431
    Abstract: A liquid containing member that can supply a liquid having a uniform concentration of a precipitating component to a liquid ejecting portion is provided. A liquid containing member includes: a liquid containing portion that can contain ink; a liquid supply port for supplying the ink contained in the liquid containing portion to a liquid ejection head; and a communication channel that is in communication with the liquid containing portion and the liquid supply port. The communication channel has a first end that is positioned at a lower end on the gravity direction side in the liquid containing portion and can suck the ink, and a second end that is positioned closer to the anti-gravity direction side than the first end is, and can suck the ink, in an in-use state in which the ink is supplied from the liquid supply port to the liquid ejection head.
