On a surface of the impervious sheet 4, a roll member 5 is disposed, and a reinforcing sheet 6 is provided covering the roll member 5. The impervious sheet 4 and the reinforcing sheet 6 are heat-sealed, and an erected state of the reinforcing sheet 6 is maintained. By maintaining the reinforcing sheet 6 in the erected state, an unfolded state keeping structure for keeping the reinforcing sheet 6 in an unfoldable state is formed.
