Abstract
An ink container includes a cylindrical member having a closed end and an opposite open end; and a flexible member covering the open end of the cylindrical member to define an ink containing portion. The flexible member has a bottom portion and a bent portion that is movable along an internal surface of the cylindrical member with consumption of the ink therein, wherein the bottom portion is less easily deformable than the bent portion and movement of the bent portion is irreversible.
