An ink jet head for ejecting ink, has an ink ejecting portion having an ink ejecting port formed thereon so as to eject ink through the ink ejecting port, a positioning portion for definitely determining the position of the ink jet head relative to an apparatus using the ink jet head when the ink jet head is fitted to the apparatus, an ink supplying portion adapted to be connected an ink supplying unit while ink is supplied to the ink jet head, and an electric connecting portion adapted to be electrically connected to an electric connecting portion on the apparatus side so as to send and receive signals. The positioning portion, the ink supplying portion and the electric connecting portion are disposed on a different surface from a surface on which the ink ejecting portion is disposed and at least one of the electric portion and the ink supplying portion is disposed on an opposite side surface to a surface on which the positioning portion is disposed.

An ink jet cartridge has a first chamber for accommodating a negative pressure producing material and having an air communication part for communication with ambient air, and a second chamber, substantially closed except for a liquid communication part, in communication with the first chamber, which second chamber contains a reservoir of ink to be supplied to the first chamber. The negative pressure producing material in the first chamber is retracted from the liquid communication part.

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.

An ink jet cartridge comprises a first chamber for accommodating a negative pressure producing material and having an air communication part for communication with ambient air, and a second chamber, substantially closed except for a liquid communication part, in communication with the first chamber, which second chamber contains a reservoir of ink to be supplied to the first chamber. A deformation prevention member is disposed within the second chamber thereby preventing or at least inhibiting deformation of the second chamber walls. A wall of the second chamber is 1.3 to 3 times as thick as a wall of the first chamber.

摘要:
A container for containing printing liquid for supplying to an ink jet head for an ink jet recording apparatus. The container includes a first chamber containing negative pressure producing material and having an air vent communicating with ambient air and a supply port for supplying printing liquid to the ink jet head. The container also includes a second chamber communicating with the first chamber via a communication port and providing a printing liquid reservoir for the first chamber. The capillary force provided by the negative pressure producing material adjacent a wall extending from the communication port and decreasing in a direction perpendicular to and towards the wall at least adjacent a part of the communication port which is uppermost in use of the container.
