The long cylinder and the obturating heads are connected by transition parts. The transition part is formed by an upper semicircle, a lower semicircle and a right-angled triangle between the upper and the lower semicircles; the diameters of all the semicircles are uniform, and the length of the short right-angle side of the right-angle triangle is equal to the length of the short side of the rectangle.
