An ink container including water-based ink for ink-jet recording and a package in which the water-based ink is accommodated, wherein the water-based ink includes an inert gas dissolved therein and an amount of oxygen dissolved in the water-based ink for ink-jet recording is less than 3 mL/L.
A packing kit for packing a container which contains a fluid together with a first gas, and thereby providing a package including the container, the packing kit including a packing bag which is adapted to fluid-tightly accommodate the container together with a second gas, a non-gas-tight case which accommodates the packing bag together with a third gas and which has a rigidity to restrain an expansion of the packing bag in a low-pressure environment where a portion of the third gas leaks from the non-gas-tight case and accordingly a pressure of the third gas becomes lower than a pressure of the second gas, and a volume-ratio reducing device which is provided inside of at least the non-gas-tight case so as to reduce a ratio of a volume of the third gas to a volume of the second gas.
