Abstract
Abstract A paper tobacco substitute which produces a neutral taste when blended with tobacco, comprising cellulose fibers and a filler, said filler comprising at least 55% by weight finely pulverized carbon particles based on the weight of the cellulose. In addition to carbon, the filler may include an alkaline earth metal carbonate or oxide such as calcium carbonate or magnesium oxide to further enhance the properties of the paper as a tobacco substitute. The carbon filled paper may be cut or shredded to simulate natural tobacco and can be used as a blend with tobacco in smoking articles.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
128 words
A tobacco substitute characterized by the smoke produced therefrom having an acrolein/tar ratio of about 3.18 × 10 - 3 and an organoleptic effect similar to natural tobacco smoke, and that when blended with tobacco and smoked reduces the total particulate matter and vapor phase yields to an extent greater than that expected from substitution of tobacco by an inert filler means in equivalent amounts, said substitute consisting of a shredded, combustible paper sheet of pulped natural organic cellulose fibers and finely pulverized carbon filler, said cellulose fibers constituting a sufficient amount of the weight of the sheet to enable sheet formation and handling during conventional paper making operations, said sheet containing at least 55% by weight carbon filler based on the weight of the cellulose fibers therein.
Claim 2
Dependent Claim
128 words
A tobacco substitute characterized by the smoke produced therefrom having an acrolein/tar ratio of about 3.18 × 10 - 3 and an organoleptic effect similar to natural tobacco smoke, and that when blended with tobacco and smoked reduces the total particulate matter and vapor phase yields to an extent greater than that expected from substitution of tobacco by an inert filler means in equivalent amounts, said substitute consisting of a shredded, combustible paper sheet of pulped natural organic cellulose fibers and finely pulverized carbon filler, said cellulose fibers constituting a sufficient amount of the weight of the sheet to enable sheet formation and handling during conventional paper making operations, said sheet containing at least 55% by weight carbon filler based on the weight of the cellulose fibers therein.
Claim 3
Dependent Claim
27 words
The tobacco substitute of claim 1 in which the paper sheet contains from 55% to 250% by weight carbon based upon the weight of the cellulose fibers.
Claim 4
Dependent Claim
27 words
The tobacco substitute of claim 1 in which the sheet contains an additional filler selected from the group consisting of an alkaline earth metal carbonate or oxide.
Claim 5
Dependent Claim
14 words
The tobacco substitute of claim 3 in which the additional filler is calcium carbonate.
Claim 6
Independent Claim
135 words
A method of reducing the total particulate matter and vapor phase yields from tobacco smoke to an extent greater than that expected from substitution of tobacco by an inert filler means in equivalent amounts comprising intimately blending with the tobacco in a smoking article a tobacco substitute characterized by smoke produced therefrom having an acrolein/tar ratio of about 3.18 × 10 - 3 and an organoleptic effect similar to natural tobacco smoke, said substitute consisting of a shredded, combustible paper sheet of pulped natural organic cellulose fibers and finely pulverized carbon filler, said cellulose fibers constituting a sufficient amount of the weight of the sheet to enable sheet formation and handling during conventional paper making operations, said sheet containing at least 55% by weight carbon filler based on the weight of the cellulose fibers therein.
Claim 7
Independent Claim
135 words
A method of reducing the total particulate matter and vapor phase yields from tobacco smoke to an extent greater than that expected from substitution of tobacco by an inert filler means in equivalent amounts comprising intimately blending with the tobacco in a smoking article a tobacco substitute characterized by smoke produced therefrom having an acrolein/tar ratio of about 3.18 × 10 - 3 and an organoleptic effect similar to natural tobacco smoke, said substitute consisting of a shredded, combustible paper sheet of pulped natural organic cellulose fibers and finely pulverized carbon filler, said cellulose fibers constituting a sufficient amount of the weight of the sheet to enable sheet formation and handling during conventional paper making operations, said sheet containing at least 55% by weight carbon filler based on the weight of the cellulose fibers therein.
Claim 8
Dependent Claim
26 words
The method of claim 5 in which said tobacco substitute contains from 55% to 250% by weight carbon based upon the weight of the cellulose fibers.
Claim 9
Dependent Claim
27 words
The method of claim 5 in which said tobacco substitute contains an additional filler selected from the group consisting of an alkaline earth metal carbonate or oxide.
Claim 10
Dependent Claim
17 words
The method of claim 7 in which the additional filler in said tobacco substitute is calcium carbonate.
Claim 11
Dependent Claim
139 words
A smoking article comprising a smoking charge of tobacco intimately blended with a tobacco substitute for reducing the total particulate matter and vapor phase yields in the smoke therefrom to an extent greater than that expected from substitution of tobacco by an inert filter means in equivalent amounts, said tobacco substitute characterized by the smoke produced having an acrolein/tar ratio of about 3.18 × 10 - 3 and an organoleptic effect similar to natural tobacco smoke, said substitute consisting of a shredded, combustible paper sheet of pulped natural organic cellulose fibers and finely pulverized carbon filler, said cellulose fibers constituting a sufficient amount of the weight of the sheet to enable sheet formation and handling during conventional paper making operations, said sheet containing at least 55% by weight carbon filler based on the weight of the cellulose fibers therein.
Claim 12
Dependent Claim
139 words
A smoking article comprising a smoking charge of tobacco intimately blended with a tobacco substitute for reducing the total particulate matter and vapor phase yields in the smoke therefrom to an extent greater than that expected from substitution of tobacco by an inert filter means in equivalent amounts, said tobacco substitute characterized by the smoke produced having an acrolein/tar ratio of about 3.18 × 10 - 3 and an organoleptic effect similar to natural tobacco smoke, said substitute consisting of a shredded, combustible paper sheet of pulped natural organic cellulose fibers and finely pulverized carbon filler, said cellulose fibers constituting a sufficient amount of the weight of the sheet to enable sheet formation and handling during conventional paper making operations, said sheet containing at least 55% by weight carbon filler based on the weight of the cellulose fibers therein.
Claim 13
Dependent Claim
38 words
The smoking article of claim 9 in which the tobacco substitute is blended with the tobacco in the smoking charge in an amount ranging from 10% to 50% by weight based on the weight of the smoking charge.
Claim 14
Dependent Claim
27 words
The smoking article of claim 9 in which said tobacco substitute contains from 55% to 250% by weight carbon based upon the weight of the cellulose fibers.
Claim 15
Dependent Claim
28 words
The smoking article of claim 9 in which the tobacco substitute contains an additional filler selected from the group consisting of an alkaline earth metal carbonate or oxide.
Claim 16
Dependent Claim
18 words
The smoking article of claim 12 in which said additional filler in said tobacco substitute is calcium carbonate.
