发明名称 MAKE-YOUR-OWN CIGARETTE
摘要 A non-smokeable cigarette unit which may be rendered smokeable by application of a tubular sleeve to the cigarette filter region has a tobacco rod, a filter plug portion and connecting material for connecting the filter plug to the tobacco rod. At least a portion of the periphery of the filter plug is of a sufficient porosity to render the cigarette unit unsmokeable. The filter has a diameter less than the diameter of the tobacco rod. The connecting material bridges a transition from the smaller filter to the larger tobacco rod. This transition portion assists in sliding the sleeve onto the larger tobacco rod to provide a smokeable cigarette.
