Patent ID: 11154088

Abstract:
A smoking article (10) comprises a tobacco rod (11) and a filter (12) in axial alignment with the tobacco rod (11). Tipping wrapper (16) circumscribes at least a portion of the filter (12) and at least a portion of the tobacco rod (11) to secure the filter (12) in axial alignment with the tobacco rod (11). The filter (12) comprises a hollow tubular element (13) at the upstream end of the filter (12) adjacent to the tobacco rod (11) and a first segment of filtration material (15) downstream from and adjacent to the hollow tubular element (13). The tipping wrapper (16) comprises a line of weakness (17) disposed at, or within 5 millimetres upstream of, the interface between the hollow tubular element (13) and the tobacco rod (11). The tobacco rod (11), the first segment of filtration material (15) and the inner surface of the hollow tubular element (13) together define a cavity (14). The cavity (14) is designed to receive the lit end of the smoking article (10) and any unburnt tobacco material when the consumer chooses to extinguish the smoking article (10).
