An extruding mechanism for a tubular bag and a method of extruding the contents of a tubular bag are provided, by which a sealing material or the like is extruded and discharged from a tubular bag with an extruding gun for a cartridge container, and which reduces the amount of discarded waste, thereby serving as one solution to environmental problems. The extruding mechanism includes an extruding gun having a holding base, and a stationary holding plate disposed on a front end portion of the holding base. The holding plate is provided with a notched portion opened upward. An extruding rod is equipped at its leading end with a pressing plate. A cylindrical member having a cylinder body is set on the holding base and accommodates the tubular bag and is opened at both ends, and a piston body is inserted into the cylinder body. A head adapter includes a base plate and has an outer surface side located on an inner surface of the stationary holding plate, an inner surface side thereof with which the opening end portions of the cylinder body are brought into contact, and an opening portion. A nozzle body has a discharge hole at its leading end, the nozzle body being attached to the opening portion of the head adapter.
