PURPOSE:To obtain a flexible bag like ink container high in ink using efficiency, by sealing the entire periphery of a pair of plastic films except a discharge port so as to adhere or fusion bond the mutually opposed surfaces thereof. CONSTITUTION:Adhering flanges 16 are provided to four sides of a pair of flexible plastic films which are, in turn, adhered at the adhering flange parts by an adhesive to obtain a sealed ink container 15 wherein the mutually opposed surfaces of said films are adhered at the peripheries thereof except an ink discharging tube 17. The ink container 15 is collapsed in a flat state without forming an ink stay part when collapsed after the received ink is discharged and the ink can be efficiently used without wasting the ink. |
