Abstract
An ink container for storing ink and an ink jet apparatus having such an ink container is provided. The ink container has an ink tank providing an enclosed space within an inner wall of the tank. The ink container is filled with inner and outer porous members having open pores for holding ink. The inner porous members are disposed within the enclosed space so as to only contact and press against other inner or outer porous members or both. The outer porous members are disposed within the enclosed space so as to contact and press against the inner porous members and the inner wall of the ink tank. This arrangement of inner and outer porous members within the ink container prevents an uneven compression distribution which occurs when conventional porous members are inserted into ink containers or when ink containers containing such conventional porous members suffer impacts. Further, the porous members can fill the entire ink container regardless of the shape of its interior, thus reducing the amount of non-dischargeable ink and leakage.
