Breakable aerosol generating article

Abstract

An aerosol generating article is provided, having a first section including a combustible heat source and an aerosol-forming substrate and a second section including a tubular element defining a recess at one end of the second section. The sections are integrally connected at a region of weakness and are separable at the region so that the element can be placed over the heat source and so that the heat source is at least partially received in the recess. The first section is upstream of the second section when the sections are integrally connected and the element is at least partially open at both ends thereof such that air may be drawn through the element. The element is either at a downstream end of the second section such that the recess forms a mouth end cavity, or is at an upstream end such that the recess forms a transfer element.

         13 . An aerosol generating article, comprising:
 a first section having a combustible heat source and an aerosol-forming substrate; and   a second section having a tubular element defining a recess at one end of the second section,   wherein the first section and second section are integrally connected at a region of weakness, the first section and second section being separable at the region of weakness to enable the tubular element to be placed over the combustible heat source, such that the combustible heat source is at least partially received in the recess,   wherein the first section is upstream of the second section when the first section and second section are integrally connected at the region of weakness,   wherein the tubular element is at least partially open at both ends thereof, such that air may be drawn along the aerosol generating article through the tubular element, and   wherein the tubular element is either at a downstream end of the second section, such that the recess forms a mouth end cavity of the aerosol generating article when the first section and second section are integrally connected, or the tubular element is at an upstream end of the second section and forms a transfer element of the aerosol generating article when the first section and second section are integrally connected.   
     
     
         14 . The aerosol generating article according to  claim 13 , wherein the tubular element is arranged such that, when the combustible heat source is received in the recess, the tubular element extends along substantially an entire length of the combustible heat source. 
     
     
         15 . The aerosol generating article according to  claim 13 , wherein the tubular element is arranged such that, when the combustible heat source is ignited and received within the recess, the tubular element sufficiently restricts a supply of air to the combustible heat source so that the combustible heat source is extinguished by the tubular element. 
     
     
         16 . The aerosol generating article according to  claim 15 , wherein the tubular element is dimensioned such that, when the combustible heat source is received within the recess, there is a frictional fit between an inner surface of the tubular element and an outer surface of the combustible heat source. 
     
     
         17 . The aerosol generating article according to  claim 13 , wherein an inner surface of the tubular element comprises a non-combustible material. 
     
     
         18 . The aerosol generating article according to  claim 17 , wherein the non-combustible material is at least one of a metal, a metal oxide, a ceramic, and a stone. 
     
     
         19 . The aerosol generating article according to  claim 13 , wherein the tubular element comprises a heat reactive material that is configured to deform in response to heat from the combustible heat source when the combustible heat source is received in the recess such that the tubular element fits tightly against the combustible heat source to restrict an air supply to the combustible heat source. 
     
     
         20 . The aerosol generating article according to  claim 19 , wherein the heat reactive material comprises an intumescent material. 
     
     
         21 . The aerosol generating article according to  claim 19 , wherein the heat reactive material comprises a heat-shrink material. 
     
     
         22 . The aerosol generating article according to  claim 13 , wherein the region of weakness is a line of weakness. 
     
     
         23 . The aerosol generating article according to  claim 13 ,
 wherein the first section and the second section are circumscribed by a wrapper, and   wherein the region of weakness comprises a weakness formation provided in the wrapper.   
     
     
         24 . The aerosol generating article according to  claim 23 , wherein the weakness formation comprises a plurality of perforations in the wrapper, the plurality of perforations circumscribing the aerosol generating article. 
     
     
         25 . The aerosol generating article according to  claim 13 , wherein the region of weakness is located at least about 10 mm from either end of the aerosol generating article. 
     
     
         26 . The aerosol generating article according to  claim 13 , wherein the region of weakness is located at least about 20 mm from either end of the aerosol generating article.
