Cigarette comprising a filter having a highly porous peripheral surface and a tubular band of impervious material to render the cigarette smokable

摘要

A non-smokable tobacco product comprises a rod-shaped tobacco element 11 coaxially interconnected to a rod-shaped filter element 12 with respective first ends of the elements adjoining. A tubular wrapper 13 of smokable material encloses the tobacco element. The first end of the filter element is wrapped by and adhered to a circumferential strip of material that is carried by the tobacco element. The filter element has a peripheral surface that is highly porous thus rendering the product unsmokable in that when air is drawn from the product through the second free end of the filter element, the major portion of such air is drawn through the peripheral surface and any air flow drawn longitudinally through the tobacco element is insufficient to propagate combustion at the tip end thereof or to cause any appreciable amount of smoke to flow through the filter element to the second end thereof. A preformed tubular band 20 of flexible substantially impervious material having a width corresponding to that of the highly porous surface of the filter element, and a circumference corresponding to that of the product is slidable on the product to a position overlying the highly porous peripheral surface to render the product smokable.
