Cigarette provided with a self-lighting device

Abstract

The invention relates to a cigarette provided with a self-lighting device comprising: a primary chemical material ( 7 ) placed at the lighting end ( 4 ) of the cigarette ( 1 ), and a secondary chemical material ( 8 ) that is incompatible with the primary material ( 7 ), said primary and secondary materials being inflammable when they are in contact with each other. The secondary material ( 8 ) is contained in a receptacle ( 9 ) initially arranged at one of the ends of the cigarette, in an arrangement preventing said secondary material and said primary material ( 7 ) from coming into contact, and said receptacle is removable and configured in such a way as to be positioned against the end ( 4 ) to be lit, in an arrangement enabling the secondary material ( 8 ) to be brought into contact with the primary material ( 7 ), the receptacle being initially fixed to the end ( 5 ) opposing the end to be lit ( 4 ).

1 . A cigarette provided with a self-lighting device comprising:
 a primary chemical material placed at the end to be lit of the cigarette,   a secondary chemical material that is incompatible with the primary material, said primary and secondary materials being flammable when they are in contact with each other,   the secondary material is contained in a receptacle initially arranged at one of the ends of the cigarette, in an arrangement preventing said secondary material from corning into contact with the primary material, said receptacle being removable, and configured in such a way as to be positioned against the end to be lit, in an arrangement enabling said secondary material to be brought into contact with said primary material,   characterised in that the receptacle is initially fixed to the inhalation end opposite the end to be lit, said receptacle being scored in such a way as to allow for an independent manipulation of the cigarette and of said receptacle.   
     
     
         2 . A cigarette according to  claim 1 , characterised in that:
 a filter is fixed by a packaging onto the inhalation end,   the receptacle is a cylindrical tube arranged in the extension of the filter, with the packaging providing the fastening of said tube onto said filter.   
     
     
         3 . A cigarette according to  claim 1 , characterised in that the receptacle is a cylindrical tube arranged in the extension of the inhalation end, said receptacle being fixed by a packaging directly onto said inhalation end. 
     
     
         4 . A cigarette according to  claim 2 , characterised in that the packaging comprises a fragile portion making it possible to manually detach the receptacle by traction, bending, twisting or rotation. 
     
     
         5 . A cigarette according to  claim 1 , characterised in that the receptacle is configured to:
 be positioned at the inhalation end opposite the end to be lit of the cigarette, so that the secondary chemical material is initially physically separated from the primary chemical material,   fit over the end to be lit, in order to bring the secondary chemical material into contact with the primary chemical material and ignite the end to be lit of the cigarette.   
     
     
         6 . A cigarette according to  claim 1 , characterised in that the receptacle has the shape of a cylindrical tube configured to fit over the end to be lit of the cigarette and bring the secondary chemical material into contact with the primary chemical material. 
     
     
         7 . A cigarette according to, characterised in that the secondary chemical material is conditioned in one or several capsules arranged in the receptacle, said receptacle comprising one or several flexible walls making it possible to break said capsules by crushing when a force of pressure is exerted on said flexible wall or walls. 
     
     
         8 . A cigarette according to  claim 1 , characterised in that the receptacle is closed by a frangible seal. 
     
     
         9 . A cigarette according to  claim 1 , characterised in that the primary chemical material comprises potassium permanganate. 
     
     
         10 . A cigarette according to  claim 1 , characterised in that the secondary chemical material comprises glycerin.
