Definitions

  • the present invention relates to a liquid container configured to be mounted to a mounting portion comprising a stopper, a liquid supply device comprising such a liquid container and a mounting portion, and an image printing apparatus comprising such a liquid supply device.
  • a known image printing apparatus is configured to print images on a sheet of paper using ink.
  • the image printing apparatuses has an ink-jet print-head configured to selectively eject ink droplets from nozzles of the print-head toward the sheet of paper.
  • a desired image is printed on the sheet of paper when the ink droplets land on the sheet of paper.
  • the image printing apparatuses has a liquid container which contains ink to be supplied to the print-head.
  • the liquid container is a liquid cartridge, which is configured to be inserted into and removed from a mounting portion provided in the image printing apparatus.
  • a liquid cartridge storing ink is also referred to as an ink cartridge.
  • the mounting portion has a locking structure configured to lock or retain the ink cartridge in a specific position in the mounting portion.
  • the mounting portion also has an urging member configured to urge the ink cartridge positioned in the mounting portion in a direction in which the ink cartridge is removed from the mounting portion when the ink cartridge is locked or retained by the locking structure.
  • the ink cartridge When the ink cartridge is moved with a great force, the ink cartridge may jump out of the mounting portion. If the ink cartridge jumps out of the mounting portion, the ink cartridge may fall down and hit a surface, and the impact of hitting the surface may cause the ink stored in the ink cartridge to splash out. The cartridge also may be broken when the ink cartridge hit the surface.
  • a known mounting portion such as a mounting portion described in JP-A-2005-288866 has a structure for preventing the ink cartridge from jumping out of the mounting portion. More specifically, the mounting portion has a resiliently deformable claw hook, and the claw hook is configured to engage an edge of an engaging recess formed in a bottom surface of an ink cartridge when the ink cartridge moves toward the outside of the mounting portion. With this engagement, the ink cartridge is prevented from jumping out of the mounting portion.
  • the claw hook when replacement of the ink cartridge is repeated and the claw hook is resiliently deformed repeatedly many times, the claw hook may be fatigued and may become unable to resiliently return to its original position or the deformation amount thereof may be reduced due to the fatigue, or the claw hook may even be fractured off. In such cases, the function of the claw hook, i.e., the prevention of the ink cartridge from jumping out of the mounting portion, is no longer effective. In order to restore its function, the mounting portion having the claw hook needs to be replaced.
  • EP 678390 A2 discloses a liquid container configured to be removed from a mounting portion.
  • a technical advantage of the present invention is that chances are reduced that a liquid container jumps out of a mounting portion, with a structure of the mounting portion, which is suitable for repeated use.
  • a liquid container is provided according to claim 1.
  • a liquid supply device comprises the liquid container as described above further comprising a guide portion comprising the first cartridge-surface, and a mounting portion having an opening.
  • the liquid container is configured to be inserted into the mounting portion in the insertion direction via the opening and to be removed from the mounting portion in the removal direction via the opening.
  • the mounting portion comprises an end portion opposite the opening in the insertion direction, an urging member configured to urge the liquid container positioned in the mounting portion toward the opening, a groove extending from the opening to the end portion in the insertion direction.
  • the groove is partially defined by a first groove-surface extending in the insertion direction and the removal direction and a second groove-surface extending in the insertion direction and the removal direction and opposing to the first groove-surface, and the guide portion is configured to be positioned and moved in the groove when the liquid container is inserted into and removed from the mounting portion.
  • the mounting portion also comprises a first stopper projecting from the first groove-surface into the groove.
  • the first cartridge-surface faces the first groove-surface when the liquid container is inserted into and removed from the mounting portion.
  • the first protrusion of the first deformable portion is configured to contact the first stopper when the liquid container is inserted into and removed from the mounting portion, and the first deformable portion is configured to resiliently deform when the first protrusion contacts the first stopper.
  • the mounting portion also comprises a retaining member configured to releasably retain the liquid container in a mount position in the mounting portion against an urging force of the urging member.
  • an image printing apparatus comprises the liquid supply device as described above, and a printing portion configured to selectively eject liquid supplied from the liquid supply device.
  • the liquid container is inserted into the mounting portion via the opening and mounted to the mounting portion.
  • the liquid container is urged by the urging member, but the retaining member retains the liquid container in the mount position against the urging force of the urging member.
  • the guide portion of the liquid container is positioned in the groove of the mounting portion.
  • the liquid container When the liquid container is released from the retained state by the retaining member, the liquid container is moved toward the opening by the urging force of the urging member.
  • the guide portion moves along the groove of the mounting portion, and the first protrusion of the first deformable portion comes into contact with the first stopper of the groove. The liquid container is stopped by this contact between the first protrusion of the first deformable portion and the first stopper.
  • the position where the liquid container stops is not limited to the position where the first protrusion of the first deformable portion contacts the first stopper.
  • the liquid container may move with the first protrusion of the first deformable portion sliding on the first stopper while the first deformable portion is resiliently deformed.
  • the velocity of the liquid container may be attenuated by the contact between the first protrusion of the first deformable portion and the first stopper, and the liquid container may be stopped after the first protrusion has passed the first stopper.
  • the liquid container that comprises the deformable portion may not be fatigued even after the liquid containers are repeatedly inserted into and removed from the mounting portion.
