Abstract

A filter tip for a smoking product comprised of a filter rod attached at one end to the smoking product. The filter rod is surrounded by a tip wrapping layer which terminates at a distance from the mouth end of the filter rod. The projecting end of the rod is tapered toward the mouth end. The taper causes smoke drawn through the filter tip to flow out obliquely with respect to the longitudinal axis of the smoking product.
