An internal peripheral level is located above the openings. A chamfer (17) is located in coincidence with the input opening, where height and width of the chamfer is equal to diameter of the input opening. The chamfer internally determines a flat contour around the input opening, and an upper plate is located between the input opening and the peripheral level.
