Aerosol-Generating Article
Patent No. EP3818883 (titled "Aerosol-Generating Article") was filed by Kt&G on Nov 13, 2019. The application was issued on Mar 5, 2025.
Patent Summary
Aerosol generating articles with adjustable aerosol flow resistance through a channel-based filter structure. The articles feature a front-end filter segment with a channel that connects to a rear-end filter segment, both containing a filter structure. The channel's cross-sectional area ratio determines the aerosol flow resistance, with the ratio being proportional to the channel and filter structure areas. This allows the aerosol flow resistance to be precisely controlled by adjusting the channel's cross-sectional area relative to the filter structure's area.
