ABSTRACT:
A cigarette comprises a tobacco rod and a filter element interattached by an air-impermeable tipping wrapper, the rod and the element abutting each other along a flat, continuous plane inclined at 45.degree. to the longitudinal axis of the cigarette. The tipping wrapper does not reach to the maximum upstream extent of the element, therefore air is able to enter the exposed air-permeable periphery of the element without the need for perforations in the air-impermeable tipping wrapper.
