The medical container includes a container body having a proximal end opening, a proximal-end edge portion surrounding the proximal end opening, a plug body sealing a mouth section a bag body including an edge portion fixed in a fluid-tight manner to the proximal-end edge portion, and a flexible reversing part surrounded by the edge portion. In a first state, the reversing part expands toward a distal end side and in a second state the reversing part expands toward a proximal end side. The medical container further includes a protection cover which can take a proximal end side mounting state in which the protection cover is mounted on the container body so as to cover the proximal end opening, and a distal end side mounting state in which the protection cover is mounted on the container body so as to cover the mouth section.
