Claims
- 1. A filter cigarette comprising a tobacco rod, a substantially cylindrical filter plug assembly having a first mouth-end filter plug segment and a second, axially aligned rod-end filter plug segment spaced apart from the first segment, means joining the tobacco rod to the second segment in axially aligned, abutting end-to-end relation, plug wrapping fixed to the first segment and to the second segment and defining a substantially cylindrical void therebetween, said plug wrapping being compressible in the region of said void, and tipping paper circumscribing the filter plug and the mouth end of the tobacco rod, either or both of said plug wrapping and said tipping paper being substantially air-impermeable, said first segment being movable along the longitudinal axis of the cigarette towards the second segment, whereby the plug wrapping in the region of said void between the first segment and the second segment is compressed, thereby decreasing the volume of said void and varying the resistance-to-draw of the cigarette.
- 2. The cigarette of claim 1 including a first contiguous band extending from the mouth end of the filter plug assembly to a position on the first segment adjacent the void and attached to the first segment for movement therewith, said means joining the second segment to the tobacco rod comprising a second contiguous band extending from a position on the tobacco rod adjacent the second segment to a position on the second segment adjacent the void, said tipping paper overlying said first and second bands and extending from the mouth end of the filter plug assembly to the tobacco rod end of the second band, said tipping paper being attached to the first band for movement therewith.
- 3. The cigarette of claim 2 including a first opening in the tipping paper and a second opening in the plug wrap positioned such that the first and second openings are movable into varying degrees of registry responsive to movement of the first segment towards the second segment, whereby the air dilution of the cigarette is varied.
- 4. The cigarette of claim 2 including a flavor generating disposed in the void and adapted to release varying amounts of a flavorant responsive to movement of the first segment towards the second segment.
- 5. The cigarette of claim 1 wherein the tipping paper extends from the mouth end of the first segment to a position on the tobacco rod adjacent the second segment, said tipping paper being attached to the first segment and including points of attachment to the plug wrapping spaced about the circumference of the inner surface of the tipping paper, said points of attachment being disposed in a plane perpendicular to the longitudinal axis of the cigarette, and intermediate the rod end of the first segment and the mouth end of the second segment.
- 6. The cigarette of claim 5 including a first opening in the tipping paper and a second opening in the plug wrap positioned such that the first and second openings are movable into varying degrees of registry responsive to movement of the first segment towards the second segment, whereby the air dilution of the cigarette is varied.
- 7. The cigarette of claim 5 including a flavor generator disposed in the void and adapted to release varying amounts of a flavorant responsive to movement of the first segment towards the second segment.
- 8. The cigarette of claim 1 wherein the tipping paper extends from a position intermediate the mouth end and the rod end of the first segment to a position on the tobacco rod adjacent the second segment, said tipping paper being attached to and joining the second segment and the tobacco rod.
- 9. The cigarette of claim 8 including a first opening in the tipping paper and a second opening in the plug wrap positioned such that the first and second openings are movable into varying degrees of registry responsive to movement of the first segment towards the second segment, whereby the air dilution of the cigarette is varied.
- 10. The cigarette of claim 8 including a flavor generator disposed in the void and adapted to release varying amounts of a flavorant responsive to movement of the first segment towards the second segment.
- 11. The cigarette of claim 1 wherein said plug wrapping and said tipping paper are substantially air-impermeable.
- 12. The cigarette of claim 11 including a first opening in the tipping paper and a second opening in the plug wrap positioned such that the first and second openings are movable into varying degrees of registry responsive to movement of the first segment towards the second segment, whereby the air dilution of the cigarette is varied.
- 13. The cigarette of claim 11 including a flavor generator disposed in the void and adapted to release varying amounts of a flavorant responsive to movement of the first segment towards the second segment.
- 14. The cigarette of claim 1 wherein said plug wrapping is substantially air-impermeable and said tipping paper is air-permeable.
- 15. The cigarette of claim 14 including a first opening in the tipping paper and a second opening in the plug wrap positioned such that the first and second openings are movable into varying degrees of registry responsive to movement of the first segment towards the second segment, whereby the air dilution of the cigarette is varied.
- 16. The cigarette of claim 14 including a flavor generator disposed in the void and adapted to release varying amounts of a flavorant responsive to movement of the first segment towards the second segment.
- 17. The cigarette of claim 1 wherein said plug wrapping is air-permeable and said tipping paper is substantially air-impermeable.
- 18. The cigarette of claim 17 including a first opening in the tipping paper and a second opening in the plug wrap positioned such that the first and second openings are movable into varying degrees of registry responsive to movement of the first segment towards the second segment, whereby the air dilution of the cigarette is varied.
- 19. The cigarette of claim 17 including a flavor generator disposed in the void and adapted to release varying amounts of a flavorant responsive to movement of the first segment towards the second segment.
- 20. The cigarette of claim 1 including a first opening in the tipping paper and a second opening in the plug wrap positioned such that the first and second openings are movable into varying degrees of registry responsive to movement of the first segment towards the second segment, whereby the air dilution of the cigarette is varied.
- 21. The cigarette of claim 1 including a flavor generator disposed in the void and adapted to release varying amounts of a flavorant responsive to movement of the first segment towards the second segment.
