THE INK CONTAINER ENSURING A RELIABLE ELECTRICAL CONNECTION AND A LIQUID COMMUNICATION WITH ITS SITE Russian patent published in 2005 - IPC

FIELD: production of a replaceable ink container for the ink feeding in an ink-jet printing system.

SUBSTANCE: the invention is pertaining to the field of production of a replaceable ink container for the ink feeding in an ink-jet printing system. At that the printing system has its site mounted on the scanning carriage. At the site has an inlet opening for a liquid and the electrical contacts electrically connected to a section of control of the printing system work. At that the replaceable container has a tank for ink, and the lower butt surface perpendicular to a leading butt surface. At that the lower butt surface forms an outlet opening for a liquid and has a form to couple with the liquid inlet opening located on the site. Besides the replaceable ink container also has a keeping information electric device coupled to the ink container connected for storage of information on the replaceable ink container and the electric contacts mounted on the leading butt surface and electrically connected with the electric device for information storage. At that each of electric contacts located on the ink container has the form to interact with each of the electric contacts on the site for a working connection with the electric device for the information storage and with a part of the printing system control and a means of a catcher located on the leading butt surface in immediate proximity to the butt surface. At that the catcher has a means of catching for engagement of a corresponding means of catching located on the mounting surface to fasten the leading butt surface of the ink to the site. The offered development also concerns to the method ensuring the electrical connection and the liquid communication between the replaceable ink container and the site. The offered method and the device ensure production of the replaceable ink containers, which one easily mounted and removed. At that an ink container installation ensures the reliable liquid and electric coupling with the printing system. At that the ink containers should be simple in production and so reducing the cost of the ink feeding, and consequently also reducing the cost of one page print.

EFFECT: the invention ensures production of the replaceable ink containers easily mounted and removed, providing the reliable liquid and electric connection with the printing system, simplification of their production, reduction of cost and consequently reducing the cost of one page print.
