  • Publication number: 20180104955
    Abstract: The liquid container has a spacer member provided in the liquid storage portion. When three directions orthogonal to each other are assumed to be a D direction, a T direction, and a W direction, in the D direction, a direction from a liquid outlet portion toward the other edge portion of the bag is assumed to be a +D direction, and the opposite direction to the +D direction is assumed to be a ?D direction, and a direction in which the dimension of the outer shape of the liquid container is smallest is assumed to be the T direction, and the spacer member has, on the +D direction side, a face inclined such that the dimension in the T direction of the spacer member increases from the +D direction side toward the ?D direction side.

  • Publication number: 20180043695
    Abstract: The liquid container is detachable from a case of a liquid ejection apparatus. The liquid container has a bag-shaped member that is flexible and has a storage portion for storing a liquid therein, and a connection member attached to the bag-shaped member. The connection member has a liquid introducing outlet into which a liquid introducing portion of the liquid ejection apparatus is inserted, a container-side electrical connection unit to which an apparatus-side electrical connection unit of the liquid ejection apparatus is connected, and a handle that pivots with respect to the connection member. In a state where the liquid container is arranged in the case, the handle is provided at a position exposed to the outside of the case, and when the liquid container is mounted to/removed from the case, the handle is brought into a second orientation in which the handle is pivoted from a first orientation.

  • Patent number: 9738082
    Abstract: An ink container that is attachable to and detachable from an ink supply apparatus that supplies ink, which is an example of a liquid, to a liquid injection apparatus, the ink container including: an ink container part that houses ink; a base member that is located at an end of the ink container part and that projects further outside than the ink container part; an ink outlet part that is provided on the base member so as to project from the base member in a V axis direction intersecting a direction in which the base member projects from the ink container part, and that is in communication with an inside of the ink container part via the base member; and a handle part that is provided on the opposite side to the ink outlet part side of the base member and that projects from the base member in a direction opposite to a direction in which the ink outlet part projects from the base member.

  • Publication number: 20170173966
    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.

  • Publication number: 20170151799
    Abstract: Provided is a liquid ejection device including a liquid container tray that can suppress change in orientation and position of a liquid container on a support surface due to the difference in size of the liquid container. The liquid ejection device includes: a casing including a guide wall: a liquid container tray configured to support a liquid container: and a recording head that ejects liquid supplied from the liquid container that is supported by the liquid container tray to a medium. The liquid container tray is configured to be inserted to or removed from a casing along the guide wall, and includes a support surface that supports the liquid container and a movable wall configured to move in at least one direction on the support surface.
