EP4637425A1 — Aerosol-generating article comprising a frame

USPTO Abstract

There is provided an aerosol-generating article (10) for use with an aerosol-generating device (90) to generate an aerosol. The aerosol-generating article (10) comprises a length extending in an x-direction, a width extending in a y-direction, and a thickness extending in a z-direction. The aerosol-generating article (10) comprises an air inlet (11) and an air outlet (12). The aerosol-generating article (10) comprises an airflow passage extending between the air inlet (11) and the air outlet (12). The aerosol-generating article (10) comprises a cavity (30). The aerosol-generating article (10) comprises one or more aerosol-generating substrates (40, 41, 42). The aerosol-generating article (10) comprises a first planar external surface (21) and a second planar external surface (22) spaced from the first planar external surface (21) in the z-direction. The aerosol-generating article (30) comprises a frame (50) positioned between the first planar external surface (21) and the second planar external surface (22). The frame (50) at least partially defines the cavity (30). The frame (50) forms at least 75 percent of a perimeter of any cross-section, in an x/y plane, of the aerosol-generating article (10) that extends through the frame. There is also provided an aerosol-generating device (90) for use with an aerosol-generating article (10), an aerosol-generating system comprising the aerosol-generating device (90) and the aerosol-generating article (10), and a method of manufacturing (1100) an aerosol-generating article (10).
