摘要： The liquid substance advancing container is constructed such that the piston is formed of a sealing part in a front part of the piston that comes in sliding contact with an inner wall of a reservoir of the barrel body and a bar member in the rear part of the piston that has a threaded section on the inner or outer periphery, is movable in a axial direction and is restrained form moving with respect to the rotational direction, a front bar-like part extended forward from the handle is formed with a threaded section that is directly or indirectly screw-fitted to the threaded section of the bar member in the rear part of the piston, and, as the handle is rotated relative to the barrel body, the piston advances and then after full advance of the piston the front bar-like part can extend and retract by multiple stages.
