Protection is sought for the shape and ornamental features of the suction part. The shank of the suction part is not hollow but single-walled and thus rather thin, in addition slightly bended. The actual suction part has, seen from the front, a more ring-shape, and, seen from the side, it is curved (convex) on the upper side and flattened on the bottom side, with openings at the sides.
