摘要： A liquid container is provided with an atmospheric air communicating port communicated with atmospheric air in an upper portion thereof, and a liquid supply port for supplying ink contained in the liquid container to a recording head in a lower portion thereof. A negative pressure producing member for retaining ink and imparting a negative pressure to the recording head is contained in the liquid container. On an upper wall in the liquid container on which the atmospheric air communicating port is provided, a plurality of ribs are integrally formed to protrude to the inside of the liquid container. A space portion is formed between the upper wall of the liquid container on which the ribs are disposed and an upper surface of the negative pressure producing member. A capillary channel for generating a capillary force is provided on the upper wall and side walls of the liquid container which form the space portion.

摘要： A liquid discharge head cartridge can assuredly supply a liquid discharge head with a liquid even when a bubble is generated within a liquid channel, and maintain excellent recording characteristics even in a configuration in which light recovery or no recovery is adopted. The cartridge includes a slit-shaped opening provided at an ink channel facing an ink-jet recording head, a filter provided at an ink introducing unit so as to contact an ink absorber, and ribs for supporting the filter that extend from an inner wall of the ink introducing unit to a substantially central portion of the filter.

摘要： 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. With the rib thus structured, it is possible to enhance the use efficiency of ink in the ink tank, while preventing ink from leaking externally, and the rib from being broken as well.

摘要翻译： 墨盒包括壳体和盖构件，当粘合在一起时提供中空容纳部分，并且在该容纳部分中包含通过层压纤维材料形成的墨吸收剂。 在盖构件上设置肋条以挤压到容纳部分中。 该肋包括与油墨吸收体的纤维层压面对角排列的第一方向肋，以及与第一方向肋正交相交的第二方向肋。 在由第一定向肋和第二定向肋围绕的位置上形成大气连通口，并且在大气连通的周围设置有挤压入容纳部的连通口引导件。 肋的高度大于通信端口引导件的高度。 肋部压缩墨水吸收剂而不被埋入其中。 利用如此构造的肋，可以提高油墨罐中的油墨的使用效率，同时防止油墨从外部泄漏，并且肋也被破坏。
