Abstract: The invention provides a liquid container capable of supplying ink to the exterior until the ink is almost depleted, and allowing simple detection of the remaining ink amount and deviated distribution of the ink component after a prolonged standing. The liquid container is provided with a first connection port and a second connection port on the bottom, communicating with a liquid chamber. The connection port is positioned closer to the end of the container bottom, while the connection port is positioned closer to the center thereof. In the connection ports, elastic members are provided so as to prevent leakage of the ink in the liquid chamber.

Abstract: A method for coupling a liquid jet head unit is to couple a liquid jet head unit for recording by discharging liquid to a recording medium with a head installation member capable of installing the head unit through an elastic member. This method comprises the steps of preparing a liquid jet head unit structured integrally with two orifice arrays substantially paralleled and a first supply opening group for supplying liquid to the orifice arrays, and a head installation member provided with a second supply opening group corresponding to the first supply opening group for supplying liquid to the liquid jet head unit, and also, an elastic member having holes corresponding to each of the supply opening groups, providing first and second coupling units for one end side and the other end side of the two orifice arrays for coupling the liquid jet head unit and the head unit installation member, respectively and coupling only one face of the liquid jet head unit and the head unit installation member using the first and second coupling units. With the adoption of this method, it is possible to implement stabilized recording on a recording medium by means of stabilized ink supply, at the same time, preventing any erroneous installation in the coupling mode.

Abstract: An ink absorber is housed inside a housing of an ink tank and is capable of retaining ink. The ink absorber has an outer surface equal to or corresponding to a shape of an internal surface of the housing and is made of a fiber material obtained by compressing a fiber body and thermally molding at least a surface thereof. An ink tank is comprised of the ink absorber and the housing. An ink jet cartridge is comprised of the ink tank and a print head. A process for producing the ink tank comprises a first molding step of molding a continuous fiber aggregate of a rod shape or a plate shape with elasticity, a step of cutting the fiber aggregate thus molded to form a fiber body, a second molding step of subjecting the fiber body to compression and thermal molding so as to provide the fiber body with an outer surface corresponding to a shape of the inside of the housing, thus forming an ink absorber and a step of inserting the ink absorber into the inside of the housing.
