An ink container includes an ink pack filled with an ink and a container case housing the ink pack. The container case includes an upper plate and a lower plate respectively covering the ink pack, one side plate provided between side parts of the upper plate and the lower plate, and two hinges coupling the upper plate and the lower plate with the side plate. The upper plate, the lower plate, the side plate and the hinges are integrally molded. The upper plate, the lower plate and the side plate are bent by the hinges so as to be thereby assembled as the container case including a housing configured to house the ink pack at a center. One ends of the upper plate and the lower plate constitute a grip and other ends of the upper plate and the lower plate constitutes an aperture.
