a neck having an opening therein,
wherein a cross-section of each of the plurality of guides has a curvature in the general shape of a letter “C” or a reversed letter “C” when each of the plurality of guides is cut by a plane through a central axis of the spiral pattern, and wherein each of the curvatures changes in a manner such that, in a liquid flow direction from the body directly towards the opening, a leading portion of the curvature is relatively tight and a trailing portion of the curvature is relatively loose.
