摘要： An ink jet head cartridge include an ink container and a porous material contained in the container for retaining the ink. A process for filling the ink container includes the steps of supplying ink in a quantity greater than that which the porous material can retain through a first port and removing through a second port at least a quantity of ink which the porous material cannot retain. The process can also be performed through a single port. At least one of the ports can also be used for communicating with a recording head portion of the cartridge.

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： A method of making a replaceable ink cartridge uses a molded, one-piece container body with an open bottom, elongated front, back and top walls, two side walls providing major surfaces of the cartridge, and a partition attached to the side walls and extending from the top wall toward the open bottom to divide the container body into first and second compartments. A sponge-like absorbent material is inserted into the second compartment through the open bottom, which is then sealed with a bottom wall, so that the cartridge has first and second chambers communicating with each other through an opening formed by a gap between the partition and the bottom wall.
