PROBLEM TO BE SOLVED: To obtain a liquid toner container of such a type that a pour-out plug of an inner bag is visible through a pour-out plug window of a carton, which shrinks approximately uniformly from all directions with a volume gradually reduced, by using a seamless tube in the inner bag. SOLUTION: An inner bag 3 to be used for the liquid toner container comprises a seamless tube made of a plastic or the like, or a balloon, which is formed of a thin film material made of rubber or the like, which is excellent in elasticity. The flexible inner bag 3 made of the seamless tube with contents received is mounted in a box formed with a lid so that a pour-out plug part 31 is visible through a pour-out plug window. Further on it, a rear wall lower extension piece is folded onto left and right sidewall lower extension pieces folded inward, and a rear face of a lower wall is stuck to a surface of the rear wall lower extension piece to form a bottom, thereby obtaining the liquid toner container in an approximate parallelopiped form. When the liquid toner container is used in a copy machine, the inner bag 3 shrinks approximately uniformly from all directions as contents are discharged and reduces its volume gradually.
