PROBLEM TO BE SOLVED: To provide a cartridge type bag used for hermetically sealing fluid contents, such as ink, and used by being attached to a printer or the like, which is totally excellent in usability, economical efficiency, disposability, and so on since a structure is simple, an air bag is not bulky, the ink in the bag does not contact air, and almost no ink is left after use. SOLUTION: The cartridge type bag 100 is formed from, for example, a laminated film bag and a tubular cover sheet 14. The laminated film bag has a discharging opening 20, made of plastic, which is joined to part of the top of the film bag. The tubular cover sheet 14 is attached so as to cover the periphery, or sides, of the bag. Sticking sections 15 of the cover sheet 14 are stuck to the surface of the bag so that the cover sheet 14 can be stripped. It is preferable that the cover sheet 14 be made of a material that is greater in stiffness than the laminated film of the bag and that the sticking area of each sticking section 15 gradually increase toward the discharging opening.
