  • Patent number: 7273273
    Abstract: A container in which is arranged a housing borne by an upper wall of the container suitable for storing a color cartridge to be refilled. The container has at least three tanks containing the different color inks. The three tanks are substantially shaped as concentrical cylinders. More particularly, the outer tank completely encompasses the intermediate tank and both are arranged concentrically around the central tank. In the operating position, i.e. with the container in the vertical position, the ink is contained in the bottom part of each of the tanks in corresponding feeding compartments. Each of the tanks extends upwardly, i.e. in the direction of the upper wall, forming corresponding back-flow compartments concentrical and disposed ring-like about the housing, each of which communicates freely with the corresponding feeding compartment below.
