1. A filter cigarette comprising:
- a substantially cylindrical tobacco rod;
a substantially cylindrical filter plug, the tobacco rod and the filter plug having substantially the same cross-sectional area and shape;
tipping paper circumscribing said filter plug and a portion of said tobacco rod;
means associated with said filter plug for lengthening and shortening said cigarette, said lengthening and shortening means being such as to retain said filter plug against removal from said cigarette; and
means for varying the air dilution value of said filter cigarette responsive of lengthening and shortening of said filter cigarette.

Abstract
A cigarette is provided having a variable length. A filter or mouthpiece slides within a sleeve attached to the cigarette, or a sleeve attached to the filter or mouthpiece slides over the cigarette. A single band is adhered to one element and a pair of bands is adhered to the other element. The single band is captive between the pair of bands so that the cigarette can be lengthened or shortened within the range allowed by the pair of bands, but the filter or mouthpiece cannot be removed from the cigarette. The variable length mechanism can be made to additionally provide variable dilution or variable flavorant.

7. A filter cigarette comprising:
-
a substantially cylindrical cigarette rod; a substantially cylindrical filter plug having a length and having a mouth end and a rod end open to the passage of air and smoke, the cigarette rod and the filter plug having substantially the same cross-sectional area and shape; a peripheral layer circumscribing said filter plug; a first section of tipping paper circumscribing said filter plug adjacent the mouth end thereof; a second section of tipping paper circumscribing a portion of said filter plug adjacent the rod end thereof and a portion of said cigarette rod adjacent said filter plug, and being adhered to said portion of said cigarette rod; and first, second and third bands having respective widths an circumscribing said filter plug in sequence between said peripheral layer and tipping paper, said first band adhered to said peripheral layer at a first preselected distance from said rod end of said filter plug and to said first section of tipping paper, said third band adhered solely to said peripheral layer at a second preselected distance from said rod end of said filter plug, said first preselected distance exceeding said second preselected distance by an amount greater than the width of said second band, and said second band adhered solely to said second tipping paper section at a third preselected distance from the end of said cigarette rod adjacent said filter plug, said third preselected distance being at least equal to said first preselected distance, whereby said filter plug is movable longitudinally between a position in which said second band abuts said third band and a position in which said second band abuts said first band, thereby lengthening and shortening said filter cigarette. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A filter cigarette comprising:
-
a substantially cylindrical cigarette rod; a substantially cylindrical filter plug having a mouth end and a rod end open to the passage of air and smoke, the cigarette rod and the filter plug having substantially the same cross-sectional area and shape; a peripheral layer circumscribing said filter plug; tipping paper circumscribing said filter plug and a portion of said cigarette rod, and being adhered to said filter plug; and first, second and third bands having respective widths and circumscribing said cigarette rod in sequence between said tipping paper and said cigarette rod adjacent said filter plug, said first band adhered to said cigarette rod at a first preselected distance from the end of said cigarette rod adjacent said filter plug, said third band adhered to said cigarette rod at a second preselected distance from said end of said cigarette rod, said second preselected distance exceeding said first preselected distance by an amount greater than the width of said second band, and said second band adhered to said tipping paper at a third preselected distance from said mouth end of said filter plug, said third preselected distance exceeding the sum of the length of said filter plug and said first preselected distance, and exceeding the sum of the length of said filter plug and the difference between said second and first preselected distances, whereby said filter plug is movable longitudinally between a position in which said second band abuts said third band and a position in which said second band abuts said first band, thereby lengthening and shortening said filter cigarette. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A cigarette comprising:
-
a substantially cylindrical cigarette rod, having a mouth end and a coal end; a mouthpiece having a mouth end, a rod end, and a mouthpiece length circumscribing the mouth end of said cigarette rod; a layer of tipping paper circumscribing said mouthpiece and a portion of said cigarette rod, said layer being adhered to said mouthpiece; and first, second and third bands having respective widths circumscribing said cigarette rod in sequence between said cigarette rod and said layer, said first band adhered to said cigarette rod at a first preselected distance from said mouth end of said cigarette rod, said third band being adhered to said cigarette rod at a second preselected distance from said mouth end of said cigarette rod, said second preselected distance exceeding said first preselected distance by at least the width of said second band and by at most said mouthpiece length, and said second band being adhered to said layer at a third preselected distance from the mouth end of said mouthpiece, said third preselected distance exceeding the sum of said mouthpiece length and said first preselected distance, and exceeding the sum of said mouthpiece length and the difference between said second and first preselected distances, whereby said layer and said mouthpiece are movable longitudinally between a first position in which said second band abuts said first band, and a second position in which said second band abuts said third band. - View Dependent Claims (30, 31, 32, 33, 34, 35)
