Abstract: The present invention relates to a standing bag type container and aims to increase a visibility of the residual liquid volume in accordance with the progress of infusion process. The standing bag type container includes a bag 10 made of soft resin films and forming at its one end a base member 20 and an outlet port 18 at the other end of the bag. A suspension of the bag 10 is done in a manner that the base member 20 is located at the top. Marks for indication of residual liquid volume are printed on the surface of the bag. An infusion liquid is charged to the bag while an air gap 109? is left, so that a residual liquid volume is verified from the liquid level. Under the suspended condition, the base member 20 has a value of width which is unchanged from the when the bag is under upright condition. The base member 20 is not collapsed and maintains its width even when the residual liquid volume is zero.
