Tobacco-Containing Consumable For Aerosol Generating Devices

Abstract

A non-combustible tobacco article for use in conjunction with a heat source to produce an inhalable aerosol includes at least one tobacco derived portion, at least one distal filter portion and at least one mouth-end filter portion held together in an overwrap; the complete article having a compressibility factor in the longitudinal axis of <10%.

1 . A non-combustible tobacco article for use in conjunction with a heat source to produce an inhalable aerosol, the article comprising
 at least one tobacco derived portion, at least one distal filter portion and at least one mouth-end filter portion held together along a longitudinal axis in an overwrap;   the complete article having a compressibility factor in the longitudinal axis of <10%, the compressibility factor being measured in the longitudinal axis by application of a force of 10 Newtons at ends of the article and measuring deflection distance as a percentage of total length of the article.   
     
     
         2 . The tobacco article according to  claim 1  arranged to have a total pressure drop <120 mm water column across the article in the longitudinal axis. 
     
     
         3 . The tobacco article according to  claim 1  arranged such that in use the article modifies a first aerosol produced by the heat source to produce the inhalable aerosol. 
     
     
         4 . The tobacco article according to  claim 1  arranged such that in use the article provides volatile components to the inhalable aerosol upon action of the heat source. 
     
     
         5 . The tobacco article according to  claim 1  further comprising induction elements dispersed within the at least one tobacco derived portion such that, in use, electromagnetic energy can be applied to the induction elements to generate heat. 
     
     
         6 . The tobacco article according to  claim 1  where the at least one tobacco derived portion contains at least one from the group of a flavourant, a humectant and a pH modifying agent. 
     
     
         7 . The tobacco article according to  claim 1  where the at least one tobacco derived portion contains a flavourant, a humectant and a pH modifying agent. 
     
     
         8 . The tobacco article according to  claim 1  where the overwrap includes at least one transparent region. 
     
     
         9 . The tobacco article according to  claim 1  where the overwrap is arranged to resist absorbing volatile and aerosol components in the at least one tobacco derived portion such that the total weight gain by absorption after use is <10% of the original overwrap weight. 
     
     
         10 . The tobacco article according to  claim 1  where the overwrap is wound in a helical direction relative to the longitudinal axis of the article. 
     
     
         11 . The tobacco article according to  claim 1  where the at least one mouth-end filter portion comprises at least two distinct regions abutted together. 
     
     
         12 . The tobacco article according to  claim 1  where the at least one mouth-end filter portion and the at least one distal filter portion separately or combined contain at least one from the group of an aesthetic element, a flavourant and an attenuant. 
     
     
         13 . The tobacco article according to  claim 1  where the at least one mouth-end filter portion and the at least one distal filter portion separately or combined contain a flavourant and an aesthetic element. 
     
     
         14 . The tobacco article according to  claim 1  where the at least one mouth-end filter portion and the at least one distal filter portion separately or combined contain an attenuant, a flavourant and an aesthetic element. 
     
     
         15 . The tobacco article according to  claim 1  where at least one of the at least one mouth-end filter portion and the at least one distal filter portion contains at least one airflow channel in the longitudinal axis. 
     
     
         16 . A process of manufacturing a tobacco article, the method comprising the steps of:
 forming at least one distal filter portion and at least one mouth-end filter portion;   arranging said filter portions within an overwrap in such a manner to form a cavity between the at least one distal filter portion and the at least one mouth-end filter portion;   filling the cavity with tobacco derived material; and   closing the overwrap material to form an integral unit.
