Reconstituted Plant Sheet For Devices That Heat Tobacco Without Burning It

Abstract

The invention relates to a reconstituted plant sheet suitable for devices that heat tobacco without burning it, said reconstituted plant sheet comprising one or two fibrous support(s) obtained by a papermaking process and comprising plant fibres, a plant extract and a solid additive.

1 . Reconstituted plant sheet comprising:
 1 or 2 fibrous supports comprising plant fibres,   a plant extract, and   a solid additive.   
     
     
         2 . Reconstituted plant sheet according to  claim 1 , also comprising an aerosol-generating agent, said aerosol-generating agent representing from 8% to 50%, in particular from 10% to 40%, more particularly from 15% to 35% by dry weight of the reconstituted plant sheet. 
     
     
         3 . Reconstituted plant sheet according to  claim 1 , in which the aerosol-generating agent is sorbitol, glycerol, propylene glycol, triethylene glycol, lactic acid, glyceryl diacetate, glyceryl triacetate, triethyl citrate or isopropyl myristate, or a mixture thereof. 
     
     
         4 . Reconstituted plant sheet according to  claim 1 , in which the weight content of dry matter of the plant fibres is from 20% to 92%, in particular from 25% to 75%, more particularly from 30% to 45%. 
     
     
         5 . Reconstituted plant sheet according to  claim 1 , in which the weight content of dry matter of the plant extract included in the reconstituted plant sheet is from 5% to 47%, in particular from 25% to 45%. 
     
     
         6 . Reconstituted plant sheet according to  claim 1 , in which the solid additive is chosen from plant dust, a diluent, a texturing agent, powdered or encapsulated flavourings or a mixture thereof. 
     
     
         7 . Reconstituted plant sheet according to  claim 1 , in which the solid additive is plant dust and the plant dust content is from 1% to 70% by dry weight relative to the total weight of said reconstituted plant sheet, in particular from 5% to 65%, more particularly from 10% to 30%. 
     
     
         8 . Reconstituted plant sheet according to  claim 1 , in which the plant is chosen from spore plants, seed plants or a mixture thereof, in particular the plant is chosen from the tobacco plant, food plants, aromatic plants, perfume plants, medicinal plants or a mixture thereof, more particularly the plant is the tobacco plant. 
     
     
         9 . Process for manufacturing a reconstituted plant sheet as defined in  claim 1  and comprising 1 fibrous support, said process comprising the following steps:
 a 1 ) providing the fibrous support, 
 b 1 ) bringing the plant extract into contact with the fibrous support, and 
 c 1 ) bringing the solid additive into contact with the fibrous support, 
 
       step b 1 ) possibly being carried out at the same time as step c 1 ), 
       said process also comprising a step:
 s 1 ) of drying after step c 1 ) of bringing the solid additive into contact with the fibrous support. 
 
     
     
         10 . Process for manufacturing a reconstituted plant sheet as defined in  claim 1  and comprising 2 fibrous supports, said process comprising the following steps:
 a 2 ) providing the 2 fibrous supports, 
 b 2 ) bringing the plant extract into contact with at least one of the 2 fibrous supports, 
 c 2 ) bringing the solid additive into contact with at least one of the 2 fibrous supports, and 
 d 2 ) stacking the 2 fibrous supports such that the solid additive is between the 2 fibrous supports, 
 
       step b 2 ) possibly being carried out at the same time as step c 2 ), 
       said process also comprising a step:
 s 2 ) of drying after step d 2 ) of stacking the 2 fibrous supports. 
 
     
     
         11 . Process according to  claim 9 , in which the fibrous support or the 2 fibrous supports are obtained by passing plant fibres into a papermaking machine, in particular the fibrous support or the 2 fibrous supports are obtained by a papermaking process. 
     
     
         12 . Process according to  claim 9 , in which the plant fibres and the plant extract are obtained according to the following steps:
 e) mixing one or more plant parts with water in order to extract the plant extract of the plant fibres,   f) separating the plant extract from the plant fibres.   
     
     
         13 . Use of the reconstituted plant sheet as defined in  claim 2  in a device for heating tobacco without burning it.
