A tipping wrapper 16 circumscribes a part of the filter and a part of the tobacco rod, and fixes the filter aligned with the tobacco rod in the axial direction. The filter is provided with: a hollow tubular element 13 at a filter upstream end adjacent to the tobacco rod; and a first segment of a filter material adjacent to downstream of the hollow tubular element. The chipping wrapper includes a weak line 17 disposed at an interface between the hollow tubular element and the tobacco rod or upstream thereof. The tobacco rod, the first segment of the filter material and an internal surface of the hollow tubular element define a recess 14. The recess is designed to receive an end on an ignition side of the smoke article and any unburnt tobacco materials when a consumer extinguishes the smoking article.SELECTED DRAWING: Figure 1
