Tubular heating element suitable for aerosolizable material
摘要
說明書
The cover 14 encircles the aerosolizable material 12, and helps to protect the aerosolizable material 12 from damage during transport and use of the article 10. During use, the cover 14 may also help to direct the flow of air into and through the aerosolizable material 12, and may help to direct the flow of aerosol through and out of the aerosolizable material 12. In this embodiment, the cover 14 comprises a wrapper that is wrapped around the aerosolizable material 12 so that free ends of the wrapper overlap each other. The wrapper thus forms all of, or a majority of, a circumferential outer surface of the article 10. The wrapper may be formed from paper, reconstituted tobacco, aluminum, or the like. The cover 14 also comprises an adhesive (not shown) that adheres the overlapped free ends of the wrapper to each other. The adhesive may comprise one or more of, for example, gum Arabic, natural or synthetic resins, starches, and varnish. The adhesive helps prevent the overlapped free ends of the wrapper from separating. In other embodiments, the adhesive and/or the cover 14 may be omitted. In still other embodiments, the article may take a different form to any of those discussed above. For example, in some embodiments the article 10 may include a filter for filtering aerosol generated in the article 10 in use.
