At least two or more layers are easily releasably stuck among the multilayered structure. On an upper layer sheet 11 on the upper face side of the flange from one easily releasable adhesive part stuck part 13 and on a lower layer sheet 12 on the lower face side of the flange from the easily releasable stuck part 13, cutting lines 3 and 4 are formed along the flange 2 respectively at different positions. The position of the cutting line 3 on the sheet layer 11 on the upper face side of the flange from the releasable layer 13 is on the inner edge side of the flange 2, and the position of the cutting line 4 on the sheet layer 12 on the lower face side of the flange from the easily releasable stuck part 13 is on the outer edge side of the flange 2.
