Patent ID: 8100134

Claim:
A ventilated smoking article comprising: a rod comprising a column of smokable material circumscribed by an air permeable wrapper; and a mouthpiece with an air impermeable outer wrapper and an air impermeable inner wrapper, the mouthpiece comprising: a ventilation tube formed of air permeable, porous thermoplastic material, the ventilation tube substantially surrounded by the air impermeable outer wrapper and the air impermeable inner wrapper; and a mixing chamber downstream of the ventilation tube, the ventilation tube having an annular air permeable wall that defines a passage in which an end portion of the rod is received, the rod extending from a rod end of the ventilation tube, and wherein an end surface of the annular wall at the rod end of the ventilation tube extends outward from the rod and being in fluid communication with the mixing chamber, wherein the interface between the annular wall of the ventilation tube and the outer surface of the end portion of the rod received in the passage is air impermeable, wherein the rod further comprises a filter element downstream of the column of smokable material wherein the filter element and the column of smokable material are joined by a band of air impermeable material, in which the band of air impermeable material circumscribes the end portion of the rod received in the passage and a portion of the rod extending from the rod end of the ventilation tube adjacent thereto.
