ventilated nozzle smoking article comprising first and second air flow paths

摘要

Patent specification: "Vented nozzle smoking article comprising first and second air flow paths". This is a variable vented smoking article (10, 30, 40, 50, 70) comprising a nozzle (12) circumscribed by a first wrap (24) and a second wrap (25). first wrap (24) and second wrap (25) are substantially air tight and movable relative to each other between a low ventilation configuration and a high ventilation configuration. the nozzle (12) comprises a first air flow path (18, 19) through the first wrap (24) or second wrap (25) and a second air flow path (26) through the first wrap (24) or the second wrapper (25). In the low ventilation configuration, an air flow in the nozzle (12) through the first air flow path (18, 19) is restricted and an air flow in the nozzle (12) through the second air flow path (26 ) is substantially unrestricted. In the high ventilation configuration, a nozzle air flow through the first air flow path and the second air flow path is substantially unrestricted.
