Smoking article

Abstract

A smoking article comprising one or more rod articles, an inner layer extending around the rod articles, and an outer layer extending around the inner layer. The inner and outer layers are integrally formed. The outer layer comprises a selection portion configured to move over an underlying part of the inner layer to select a property of the smoking article.

         23 . A smoking article comprising:
 one or more rod articles,   an inner layer extending around the rod articles,   an outer layer extending around the inner layer,   the smoking article comprises a limiter to limit movement between the inner layer and the outer layer, and   the limiter comprises a slot defined by one of the inner and outer layers, and a limiter element moveable within the slot to limit movement,   the smoking article further comprising a ventilation area defined by the other of the inner and outer layers from the layer defining the slot,   wherein the ventilation area is movable relative to the slot, such that an area of overlap of the slot and ventilation area controls a ventilation of the smoking article.   
     
     
         24 . The smoking article as claimed in  claim 23  wherein a portion of the outer layer is frangibly connected to a further part of the outer layer and/or the underlying part of the inner layer is frangibly connected to a further part of the inner layer. 
     
     
         25 . The smoking article as claimed in  claim 23 , wherein the outer layer, and optionally also the inner layer, comprises a forward part and a rearward part longitudinally rearward of the forward part. 
     
     
         26 . The smoking article as claimed in  claim 25 , wherein the outer layer comprises a selection portion configured to move over an underlying part of the inner layer to select a property of the smoking article and wherein the selection portion is at an interface between the forward and rearward parts. 
     
     
         27 . The smoking article as claimed in  claim 26 , wherein the forward part is frangibly connected to the rearward part and configured to detach from the rearward part on application of a force. 
     
     
         28 . The smoking article as claimed in  claim 23 , comprising an indexing mechanism configured for indexing movement between the outer layer and a said rod article. 
     
     
         29 . A smoking article assembly for forming two smoking articles, comprising:
 rod articles for forming the smoking articles,   an inner layer extending around the rod articles,   an outer layer extending around the inner layer, and   a limiter for each smoking article to limit movement between the inner layer and the outer layer, wherein   the limiters each comprise a slot defined by one of the inner and outer layers, and a limiter element moveable within the slot to limit movement,   the smoking article assembly further comprising a ventilation area for each smoking article defined by the other of the inner and outer layers from the layer defining the slots,   wherein each ventilation area is movable relative to one of the slots, such that an area of overlap of the slot and ventilation area controls a ventilation of the smoking article, and   wherein the smoking article assembly is configured to be cut into two separate smoking articles.   
     
     
         30 . The smoking article assembly as claimed in  claim 29 , wherein the limiter elements are each initially at an end of a slot and arranged such that the two smoking articles are rotatable in a same sense on the two separated smoking articles. 
     
     
         31 . A blank for wrapping around one or more rod articles to form a smoking article, the blank comprising:
 a first area for forming an inner layer extending around the rod articles,   a second area for forming an outer layer extending around the inner layer, and   wherein one of the first and second areas defines a slot and a limiter element, and the other of the first and second areas defines a ventilation area, wherein, when the blank is wrapped around one or more rod articles to form a smoking article, the limiter element is moveable within the slot to limit movement and the ventilation area is movable relative to the slot, such that an area of overlap of the slot and ventilation area controls a ventilation of the smoking article.   
     
     
         32 . The blank as claimed in  claim 31 , wherein the blank is configured to wrap around rod articles to form two smoking articles,
 wherein the one of the first and second areas defining a slot and a limiter element defines a slot and a limiter element for each of the two smoking articles and the other of the first and second areas defining a ventilation area, defines a ventilation area for each of the two smoking articles, and   wherein the blank is configured to be cut into two sections for two separate smoking articles.   
     
     
         33 . The blank as claimed in  claim 32 , wherein the first area comprises a selection portion for each smoking article and wherein the limiter couples the selection portion of each smoking article to the underlying part of the inner layer, and
 the limiter of each smoking article is configured such that the selection portion of each of the two smoking articles is rotatable in a same sense on the two separated smoking articles.   
     
     
         34 . The blank as claimed in  claim 33 , wherein the limiter element is initially at an end of each slot and arranged such that the two smoking articles are rotatable in a same sense on the two separated smoking articles. 
     
     
         35 . A method of manufacturing a smoking article comprising:
 providing one or more rod articles,   wrapping a blank around the rod articles,   wherein the blank is wrapped to form an inner layer extending around the rod articles, and the blank is further wrapped to form an outer layer extending around the inner layer,   wherein the blank defines a slot and a limiter element on one of the inner and outer layers, and a ventilation area on the other of the inner and outer layers, wherein an area of overlap of the slot and ventilation area controls a ventilation of the smoking article.   
     
     
         36 . The method as claimed in  claim 35 , wherein providing one or more rod articles comprises providing rod articles for forming two smoking articles,
 wherein the blank defines a slot, a limiter element and a ventilation area for each smoking article, and   the method further comprises cutting the wrapped blank to form two separate smoking articles.
