A liquid container includes a container body (2) formed with a liquid supply port (3), and a container-side fixing structure (7) which releasably regulates movement of the liquid container in.an outward pulling direction in cooperation with apparatus-side fixing structure provided for the container mounting part in a state where the liquid container is mounted onto the container mounting part. The container-side fixing structure (7) has a guide groove (16) into which a fixing pin of the apparatus-side fixing structure can be inserted, and which guides the fixing pin in mounting and removal operations of the liquid container to and from the container mounting part. The guide groove (16) includes a fixing part (18) which engages the fixing pin to regulate the movement of the liquid container (1) in the pulling direction in the state where the liquid container is mounted to the container mounting part. A slanted entrance surface (22) is located at an entrance part of the guide groove, which slanted entrance surface slants so that a groove depth decreases in the movement direction of the fixing pin that relatively moves in association with an inserting operation of the liquid container into the container mounting part.

摘要:
There is provided an ink cartridge which is formed from an ink-filled ink pack and a hermetic outer shell case for housing the ink pack and which supplies ink to a recording head by means of application of air pressure to a space between the outer shell case and the ink pack. The outer shell case is formed by coupling an upper case and a lower case together. The ink-filled ink pack is housed in the lower case, and the upper case is laid on the lower case from above. The upper and lower cases are hermetically sealed by vibratory welding or heat welding, thus constituting the ink cartridge.

An ink cartridge (1) attachable to an ink jet printer, includes a liquid chamber (5) for accommodating an ink liquid (4), a liquid supply port (7) to be connected to a liquid receiving portion (2a) on the ink jet printer side, a liquid passage (9) for causing the liquid chamber (5) to communicate with the liquid supply port (7), and an ink end sensor (13) forming a part of the liquid passage (9) and serving to detect a presence or absence of the ink liquid (4) in the liquid chamber (5). The liquid passage (9) on a downstream of the ink end sensor (13) is provided with a buffer chamber (15) capable of storing the ink liquid (4) to be supplied to the liquid supply port (7) and supplying the ink liquid in a constant amount after the ink end sensor (13) detects that the liquid is not present. An amount of storage of the liquid in the buffer chamber (15) is set tobe substantially 10% of aneffective amount of the ink liquid to be accommodated in the liquid cartridge (1).
