A container forming material is folded to form a stage along an outer side of the upper surface periphery of a peeling portion thereof. In addition, the container forming material and a pinching tab are formed so that they are not in contact with each other. The interior and the exterior of the upper surface periphery at the peeling portion are both shaped to form a corner. The package such as the blister package is formed so that a distance between vertexes of the corners is shorter than a width of the upper surface periphery except the peeling portion.;COPYRIGHT: (C)2002,JPO
