PROBLEM TO BE SOLVED: To prevent defective molding from occurring on the wall of the long side of a bottomed container.SOLUTION: On an outer face 22L of the long side of a punch 20, a long side path 27L is structured to raise a workpiece 35 to be molded, between the outer face 22L and the inner face of a cavity 11, and a slidingly contacting face 25L of the long side is formed to make the rising workpiece 35 to be molded contact slidingly. On the outer face 22S of the short side of the punch 20, a short side path 27S is structured to raise the workpiece 35 to be molded, between the outer face 22S and the inner face of the cavity 11, and a slidingly contacting face 25S of the short side is formed to make the rising workpiece 35 contact slidingly. The height of the long side slidingly contacting face 25L on the basis of the bottom pressing face 21 is minimal at both longitudinal ends in the direction of the length of the outer face 22L of the long side and increases toward the center in the direction of the length of the outer face of the long side. |
