Definitions
- This invention relates to smoking articles such as cigarettes, cigars and cigarillos, and is concerned with the reduction of sidestream smoke from smoking articles.
- Sidestream smoke is that which is produced when the article is alight but not being drawn on by the smoker.
- Mainstream smoke is that which is generated when the smoking article is drawn on by the smoker; the chemistries of mainstream and sidestream smokes are different.
- the present invention uses activated carbon to modify the smoke of a smoking article.
- activated carbon has been used in smoking articles, and for various purposes, virtually ever since its excellent adsorbent properties became known.
- GB-A-1512352 shows the use of activated porous particles of carbon adhered to tobacco in the tobacco rod to affect mainstream smoke.
- GB-A-1348580 shows a sheet of reconstituted tobacco material containing activated carbon used as a main material for making cigarettes which gave a reduction in particulates and nicotine in mainstream smoke.
- the present invention is contrasted with all of this prior art by providing in a tobacco rod an activated carbon for having an effect on the chemistry of smoke while not being limited to the use of low permeability papers, and specifically not to papers of ⁇ 10 CORESTA. Furthermore, the present invention provides the addition of activated carbon in specific particulate form in reconstituted tobacco sheet to the tobacco rod of the smoking article in such a way that greater mildness of the smoking article is perceived by the smoker in the mainstream smoke, and at the same time there is a reduction in sidestream smoke over a wide range of porosities of the wrapper of the article and in particular with porosities high enough that special precautions do not have to be taken to prevent self- extinction of the article.
- the activated carbon particle should preferably be of vegetable origin since they will then contain minute traces of metals, which assist in the firm adsorption of (particularly) aldehydes from the smoke and indeed may chelate with such compounds. These are compounds the removal of which is particularly critical for improving mildness of perception of the article when smoked. At the same time, however, the activated carbon does not diminish and may even increase certain beneficial volatile components of the smoke.
- the reconstituted tobacco sheet containing the activated carbon particles may be made by conventional techniques for making such sheets, which in their turn resemble conventional paper-making techniques, the sheet then being shredded for incorporation with shredded tobacco which will be the material of the tobacco rod.
- the invention therefore includes within its scope a blend of shredded tobacco and of reconstituted tobacco sheet with the latter containing activated carbon .
- the handling of the sheet may cause loss of carbon particles and the reconstituted tobacco sheet may be coated or sized in order to assist retention of the particles in it, and in particular the particles may themselves be micro- encapsulated before incorporation. This latter has the advantage of increasing the size of the particles and therefore their retention mechanically and the uniformity of size but, perhaps surprisingly, does not affect their activity.
- Example 1
- Cigarettes were made from a mixture of US flue- cured and Burley tobaccos, cut rolled stem and expanded tobaccos, processed and cut to 32 cuts per inch ("cpi") . Incorporated in the shredded tobacco were 20% of a reconstituted tobacco sheet equally cut and containing 30% of activated carbon particles from coconut, of mean particle size 37 ⁇ m and ranging in particle size from 0.5 ⁇ m to 150 ⁇ m. Control cigarettes were made identically but with the omission of the activated carbon particles. The cigarettes were 84 mm long, 7.9 mm diameter, unfiltered. The wrapping was an 80 CORESTA flax-based paper, with 2% potassium citrate burn enhancer.
- Example 2 Cigarettes and controls were prepared using the same tobacco blend and reconstituted tobacco sheet as in Example 1, but using respectively papers of 25, 50, 80 and 180 CORESTA units porosity. Sidestream smoke from the inventive cigarettes and from the controls had significant reductions both in semi-volatiles and in nicotine content, as seen in Table 3. Increased carbon monoxide and carbon dioxide production is assumed to be due to the presence of the particulate carbon in the tobacco sheet .
