DEVICE FOR SELF-LIGHTING OF A CIGARETTE, COMPRISING INCOMPATIBLE CHEMICAL MATERIALS THAT GENERATE SUFFICIENT THERMAL ENERGY TO LIGHT THE END OF SAID CIGARETTE WHEN THEY ARE IN CONTACT WITH ONE ANOTHER

The invention relates to a device for self-lighting of a cigarette (1), comprising a primary chemical material and a secondary chemical material, said chemical materials being incompatible and generating sufficient thermal energy to light the end (4) of said cigarette when they are in contact with one another, -the primary chemical material is placed in a capsule (70) intended to be fixed at the end to be lit (4) of the cigarette (1), -the secondary chemical material is disposed in a receptacle (80) designed to be positioned at the end to be lit (4) of the cigarette (1) in an arrangement that allows said secondary material to be brought into contact with the primary material, characterized in that: -the capsule (70) is made of an airtight and moisture-tight combustible material, said capsule having at least one puncturing zone, -the receptacle (80) incorporates a sealed container containing the secondary chemical material, said reservoir comprising a pointed end piece (82) the rigidity of which is sufficient to pierce the capsule (7) in its puncturing zone and through which said secondary chemical material can flow.
