Smoking article

Abstract

There is described an aerosol generating article, the aerosol generating article comprising an aerosol generating material and a laminate wrapper arranged around the aerosol generating material, the laminate wrapper comprising at least three layers; wherein the outermost layer of the laminate wrapper comprises a lacquer, an intermediate layer comprises a non-combustible material, and the innermost layer comprises paper; and wherein at least part of the innermost layer is disposed in contact with the aerosol generating material. The aerosol generating article may serve to prevent a user lighting or igniting the aerosol generating material in the aerosol generating article.

         4 . A wrapper according to  claim 1 , wherein the wrapper consists of three layers. 
     
     
         5 . A wrapper according to  claim 1 , wherein the lacquer is an acrylic lacquer. 
     
     
         6 . A wrapper according to  claim 1 , wherein the peripheral layer which comprises a lacquer has a dynamic coefficient of friction of from 0.4 to 1.0. 
     
     
         7 . An aerosol generating article, the aerosol generating article comprising an
 aerosol generating material and a laminate wrapper arranged around the aerosol generating material, the laminate wrapper comprising at least three layers;   wherein the outermost layer of the laminate wrapper comprises a lacquer, an intermediate layer comprises a non-combustible material, and the innermost layer comprises paper;   and wherein at least part of the innermost layer is disposed in contact with the aerosol generating material.   
     
     
         8 . An aerosol generating article according to  claim 7 , wherein the aerosol generating material comprises tobacco. 
     
     
         9 . An aerosol generating article according to  claim 7 , wherein the aerosol generating material is a rod of aerosol generating material, and the wrapper circumscribes at least the end of the rod that is distant from the user's mouth in use. 
     
     
         10 . An aerosol generating article according to  claim 9 , wherein the wrapper circumscribes the rod over at least 25% of the rod length. 
     
     
         11 . An aerosol generating article according to  claim 7 , further comprising a filter and/or a cooling element. 
     
     
         12 . An aerosol generating article according to  claim 11 , wherein the aerosol generating article comprises a filter and a cooling element, and wherein the cooling element is arranged between the aerosol generating material and the filter. 
     
     
         13 . An aerosol generating assembly comprising an aerosol generating article according to  claim 7  and a heater. 
     
     
         14 . An aerosol generating assembly according to  claim 13 , wherein the assembly is a tobacco heating product. 
     
     
         15 . An aerosol generating assembly according to  claim 13 , wherein the heater is a device into which the aerosol generating article is at least partially inserted muse. 
     
     
         16 . A system comprising an aerosol generating device and an aerosol generating article according to  claim 7 . 
     
     
         17 . (canceled) 
     
     
         18 . A method of preventing a user lighting or igniting an aerosol generating material in an aerosol generating article, the method comprising wrapping an aerosol generating material in a laminate wrapper, the laminate wrapper comprising at least three layers;
 wherein the outermost layer of the laminate wrapper comprises a lacquer, an intermediate layer comprises a non-combustible material, and the innermost layer comprises paper;   and wherein at least part of the innermost layer is disposed in contact with the aerosol generating material.
