Title (EN) SMOKING ARTICLE WITH COMBINED VENTILATION AND FILTRATION EFFICIENCY ADJUSTMENT
(FR) ARTICLE À FUMER AVEC RÉGLAGE COMBINÉ DE LA VENTILATION ET DE L'EFFICACITÉ DE FILTRATION
Abstract: front page image
(EN)The invention relates to a smoking article (10) comprising a tobacco rod (12) and a filter, the filter comprising a filter unit (14) comprising a first segment (16) of filtration material; a second segment comprising a tubular element (18) of filtration material upstream of the first segment (16), the tubular element (18) having an outer diameter (D2) and an inner diameter (D1). An inner surface of the tubular element (18) is substantially air impermeable. The second segment further comprises a frangible or irreversibly collapsible flow restrictor (24) disposed in the tubular element (18). When the flow restrictor (24) is in a substantially unbroken or non-collapsed state, the filter unit (14) has a first RTD. When the flow restrictor (24) is broken or collapsed, the filter unit (14) has a second RTD, the second RTD being smaller than the first RTD.
(FR)L'invention concerne un article à fumer (10) comprenant une tige de tabac (12) et un filtre, le filtre comprenant une unité de filtre (14) comprenant un premier segment (16) de matériau de filtration ; un second segment comprenant un élément tubulaire (18) de matériau de filtration en amont du premier segment (16), l'élément tubulaire (18) ayant un diamètre extérieur (D2) et un diamètre intérieur (D1). Une surface intérieure de l'élément tubulaire (18) est sensiblement imperméable à l'air. Le second segment comprend en outre un limiteur de débit cassable ou repliable de manière irréversible (24) disposé dans l'élément tubulaire (18). Lorsque le limiteur de débit (24) est dans un état sensiblement non cassé ou non replié, l'unité de filtre (14) a un premier RTD. Lorsque le limiteur de débit (24) est cassé ou replié, l'unité de filtre (14) a un second RTD, le second RTD étant plus petit que le premier RTD.
