  • Patent number: 7393089
    Abstract: A method of refilling an ink bag that is used in an ink jet recorder, the ink bag is initially filled with ink through an opening in the bag, and is sealed after the ink bag is initially filled. The method comprises the steps of removing the ink bag from the ink jet recorder, positioning the ink bag, inserting an ink needle into a separate opening in the ink bag that is different than the first opening through which the ink bag is initially filled with ink, discharging ink from the ink bag through the second opening, and charging the ink bag through the second opening with a specified quantity of ink.

  • Publication number: 20080049083
    Abstract: A liquid container capable of determining whether ink is filled into a correct liquid container in a liquid-filling process, when there are products having the same misinsertion preventing shapes but different liquid capacities, is provided. A liquid container 11 is detachably mounted on a liquid ejecting apparatus 13 and has a side face parallel to a fitting direction of a container body 31. The liquid container 11 includes a fittingness-determination portion that extends in the fitting direction and enables fittingness determination depending on a position thereof in a direction perpendicular to the fitting direction, and a filling-determination portion that is formed at the fittingness-determination portion and enables determination of the amount of liquid to be filled in the container body 31.
