摘要： An ink container includes a casing, an air vent which is located in the casing, an ink supply opening for supplying ink out of the casing, and an ink absorbing material that is contained in the casing. The ink absorbing material retains ink therein, and has a generally rectangular parallelopipedal shape defined by sides of the ink absorbing material, and also has an ink supply portion for supplying ink to the ink supply opening. The ink absorbing material includes corner portions which are located between adjacent sides of the ink absorbing material. A preventing means prevents complete surface contact between the casing and said ink absorbing material by providing spaces between the casing and ink absorbing material which are in fluid communication with each other with a given space that is adjacent to a particular one of the corner portions that is most remote from the ink supply portion. The air vent is in fluid communication with the spaces.

摘要： An ink container, as well as a method of making the same, which has ink absorbing material for retaining ink, a casing for holding the ink absorbing material, an ink supply port through which ink is withdrawn from the absorbing material, and an air vent. The air vent and ink supply port are each provided adjacent to different longitudinal halves of the ink absorbing material, and the casing is initially filled with an amount of ink which is larger than the quantity of ink which can be retained by the ink absorbing material. Then, ink adjacent to the air vent is removed to such an extent that the casing contains the quantity of the ink which the ink absorbing material can retain. Thus, ink is retained at a higher density adjacent to the ink supply port than adjacent to the air vent.
