Definitions
- This invention relates to wrappers for smoking articles such as cigarettes and especially to a wrapper construction in which burn rate is controlled.
- Affixing bands of non-porous paper, which contain cellulose, to a cigarette wrapper presents the problem of increasing the cellulose pyrolysis products from the ignited cigarette. It is known that the pyrolysis products from cellulose are often subjectively undesirable to smokers. These products may have an undesirable effect upon, for example, taste. Consequently, it is desirable to produce a wrapper construction for smoking articles such as cigarettes that would control burn rate without adversely affecting the subjective impact of the smoking article to the smoker.
- a wrapper and smoking article such as a cigarette
- the wrapper is formed from a web of porous base paper having circumscribing bands cut from a sheet of reconstituted tobacco, such as BL sheet, affixed to it.
- Reconstituted tobacco sheet is typically a slow burning material which is non-porous.
- the bands of reconstituted tobacco sheet are affixed to the base in selected regions by using a standard adhesive.
- the burn rate of the smoking article is controlled because the bands of reconstituted tobacco sheet burn at a different rate than the remainder of the porous base wrapper.
- the use of bands cut from sheets of reconstituted tobacco provides burn rate control while maintaining the desirable properties of the smoking article.
- FIG. 1 illustrates an embodiment of cigarette 10 manufactured according to the present invention.
- Cigarette 10 is comprised of base wrapper 20, bands 30 affixed to base wrapper 20 at selected intervals and tobacco column 12.
- bands 30 may be affixed to base wrapper 20 at any interval desired.
- bands 30 are 5-10 mm wide and are spaced 15-20 mm apart. It has been found that the use of 4 or 5 bands is preferable.
- BL sheet is formed by digesting scraps of tobacco along with other ingredients into a slurry. The slurry is held in a tank for a predetermined period of time. The slurry is then poured onto a continuous steel belt which is passed through a series of dryers. Thus, the moisture in the slurry is driven off by the application of heat. The BL sheet is removed from the belt after drying.
- the cast sheet process is similar to the BL sheet process but the tobacco slurry is generally not held in a tank during processing.
- the cast leaf process involves mixing tobacco dust particles, a binder and other agents such as humectants or preservatives in an aqueous media to form a slurry. Air trapped within the slurry is removed. The slurry is then cast onto a continuous stainless steel belt or other supportive device where it is dried to form a reconstituted tobacco sheet. The sheet is removed after drying.
- the cast leaf process is more particularly described in copending, commonly assigned application Serial Number 07/ (PM 1415), "Reconstituted Tobacco Sheets And Methods For Producing And Using The Same.”
- RL sheet is formed by a process similar to paper making in which a tobacco slurry is fed over a Fourdrinier wire arrangement. The moisture in the slurry is driven off by letting it flow through the wire arrangement while the slurry remains on top of the wire arrangement.
- BLsheet is, however, preferred because the resulting strip is less porous than the other varieties of tobacco sheet. Therefore, the use of BL sheet will result in greater control of the burn rate of the cigarette in the region of the band due to its low porosity.
- FIGS. 2 and 3 more clearly illustrate bands 30 affixed to base wrapper 20.
- Attachment of bands 30 to base wrapper 20 may be either to the inner surface of base wrapper 20 or to the outer surface of base wrapper. However, attachment to the inner surface of base wrapper 20 is preferable in order to maintain a more pleasing appearance of the cigarette.
- Bands 30 may be affixed to base wrapper 20 using known adhesives, for exam- pie polyvinyl acetate.
