Abstract
A novel cigarette structure is provided which produces an approximately uniform delivery of flavour along its length as the cigarette is smoked. The filler rod of the cigarette has a strip of more highly-flavoured tobacco to one side or to two sides of the rod, with the remainder of the cross-section of the rod being formed of lower flavoured tobacco, and has a higher proportion of the more highly-flavoured tobacco than the lower flavour tobacco at the lighting end. The cigarette filler rod of improved smoking characteristics may be formed by a simplified assembly procedure.
Claims7
A novel cigarette having a tobacco filler rod in a paper tube, comprising a first blend of shredded tobacco lamina material having a first flavour/tar ratio in a strip within the cross-section of the rod, a second bland of shreded tobacco lamina material having a higher flavour/tar ratio than said first blend provided in a strip to one side of the cross-section of said rod, and a lighting end having a higher proportion of said higher flavour/tar ratio tobacco in the cross-section of said rod than in the cross-section of said rod other than at said lighting end.
In a method of forming a cigarette filler rod in which tobacco is fed from a hopper as a shower of tobacco particles which is collected on a tobacco filler rod-forming and -conveying surface, the improvement wherein:
- a first blend of shredded tobacco lamina material having a first flavour/tar ratio is located in a first side of the thopper corresponding to the tobacco closest to the filler rod-forming and -conveying surface in the tobacco filler rod,
- a second blend of shredded lamina material having a higher flavour/tar ration than said first blend is located in a second side of the hopper corresponding to the tobacco farthest from the filler rod-forming and -conveying surface in the tobacco filler rod,
- higher flavour/tar ratio tobacco is trimmed from said filler rod and said trimmed tobacco is recycled to said first side of said hopper to form part of said first blend, and
- the quantity of higher flavour/tar ratio tobacco is increased at predetermined locations along the length of the filler rod corresponding to the lighting end of a cigarette formed from said rod.
