  • Publication number: 20050185034
    Abstract: A liquid container detachably mountable to a mounting portion of an ink jet recording apparatus in a slot-like mounting configuration where the liquid container is supported between a pair of engaging portions that respectively engage with a corresponding pair of locking portions on the mounting portion of the recording apparatus. The liquid container is supported in an upright configuration and includes a display portion on an upper side thereof, and a light emitting portion which emits light for display by the display portion. Because the display portion is disposed on an upper side, a user can confirm the display despite the mounting arrangement of the liquid container in the recording apparatus.

  • Patent number: 6827431
    Abstract: An ink tank comprises a housing and a cover member, providing a hollow containing portion when bonded together, and in this containing portion, ink absorbent formed by laminating fiber material is contained. On the cover member, a rib is provided to extrude into the containing portion. This rib comprises a first directional rib arranged diagonally to the fibrous lamination face of the ink absorbent, and a second directional rib that intersects with the first directional rib orthogonally. On the position surrounded by the first directional rib and the second directional rib, an atmosphere communication port is formed, and around the atmosphere communication, the communication port guide that extrudes into the containing portion is arranged. The height of the rib is larger than that of the communication port guide. The rib presses the ink absorbent without being buried in it.

  • Publication number: 20040233259
    Abstract: An ink tank is provided which can apply an optimum negative pressure stably by a valve of a simple structure. To this end, the ink tank of this invention has a valve and a damper section installed in an ink flow path. The valve deforms when the negative pressure in the ink supply port is greater than a predetermined level, to temporarily open the ink flow path to introduce ink from the ink accommodation portion to the ink supply port. The damper section is installed between and communicates to the ink supply port and the valve in the ink flow path. The damper section is formed of a resilient member more easily deformed than the valve and applies a negative pressure to the interior of the ink supply port by an elastic recovery force of the resilient member.

  • Publication number: 20040233258
    Abstract: This invention provides an ink tank capable of a stable ink supply to a print head by using a simple valve construction. In one preferred example, an ink path is closed by a lip portion of a valve rubber engaging a flange, and an angle formed by an inner surface of an opening in the lip portion and an engagement surface of the flange is an acute angle.

  • Publication number: 20040227795
    Abstract: An ink tank in which an air communication passage and a pressure regulator valve passage are formed by covering grooves, etc., with a film is fabricated in a simple manufacturing process. Specifically, an atmosphere communication hole and a major part of an air communication passage are formed in the same surface on which a film for forming a valve passage is attached. By virtue of this, the process of attaching a major part of the air communication passage film and the process of attaching the valve film can be performed in a single process step. This simplifies the process of attaching the films.

  • Publication number: 20040076447
    Abstract: A tank includes a container for accommodating an ink, a removal preventing pawl which is provided at a rear surface of the container and engaged with a tank holder and a latch lever which is provided at a front surface of the container opposite to the rear surface so as to be elastically displaced and which has a latch pawl engaging with the tank holder. The height of a rear wall of the holder to which such tank is mounted is set to be lower than the height of the tank. The height of the side surface of the holder corresponding to a side surface of the container is set to the lower than the height of the liquid tank. Thus, the container abuts the upper end of peripheral wall of the tank holder to be rotated about this upper end so that a part of the side surface of the container is protruded externally of the holder. The container can be removed from the tank holder by using such rotational operation.
