An Aerosol Generating Article and Method of Manufacturing the Same

Abstract

An aerosol generating article for use with an aerosol generating device includes a substantially planar aerosol generating substrate and a wrapping member surrounding the substantially planar aerosol generating substrate to form a substantially planar aerosol generating article. The wrapping member includes a window aligned with part of the aerosol generating substrate, and optionally includes a removable portion covering the window.

1 . An aerosol generating article for use with an aerosol generating device, the aerosol generating article comprising:
 a substantially planar aerosol generating substrate;   a wrapping member surrounding the substantially planar aerosol generating substrate to form a substantially planar aerosol generating article;   wherein the wrapping member comprises a window aligned with part of the aerosol generating substrate.   
     
     
         2 . The aerosol generating article according to  claim 1 , wherein the wrapping member comprises a sheet material and the window comprises a die-cut portion formed in the sheet material. 
     
     
         3 . The aerosol generating article according to  claim 1 , wherein the aerosol generating substrate comprises a main surface, the window is positioned adjacent to the main surface and has an area which is smaller than an area of the main surface. 
     
     
         4 . The aerosol generating article according to  claim 1 , wherein the wrapping member extends beyond an end of the aerosol generating substrate to form a mouth-end portion of the article. 
     
     
         5 . The aerosol generating article according to  claim 1 , wherein the wrapping member comprises a removable portion covering the window and one or more lines of weakness defining a periphery of the removable portion, and the removable portion is removable by a user prior to use of the aerosol generating article in an aerosol generating device. 
     
     
         6 . The aerosol generating article according to  claim 5 , wherein the one or more lines of weakness comprise one or more perforations. 
     
     
         7 . The aerosol generating article according to  claim 1 , wherein the substantially planar aerosol generating substrate has a flat rectangular shape having a pair of main surfaces and the wrapping member comprises a pair of rectangular sheets attached, respectively, to the pair of main surfaces. 
     
     
         8 . The aerosol generating article according to  claim 1 , further comprising a support member forming a mouth-end portion of the article, and the support member has a tubular form configured to receive a downstream end of the aerosol generating substrate. 
     
     
         9 . The aerosol generating article according to  claim 1 , wherein the wrapping member has a porous inner surface facing towards the aerosol generating substrate for absorbing condensation and an anti-stick outer surface facing away from the aerosol generating substrate. 
     
     
         10 . The aerosol generating article according to  claim 9 , wherein the wrapping member comprises an anti-stick coating on the outer surface. 
     
     
         11 . A method of manufacturing an aerosol generating article for use with an aerosol generating device, the method comprising:
 providing a substantially planar aerosol generating substrate;   providing a wrapping member comprising a window;   wrapping the substantially planar aerosol generating substrate with the wrapping member to form a substantially planar aerosol generating article and aligning the window in the wrapping member with part of the aerosol generating substrate.
