Benefits of technology

[0008] Accordingly, it is an object of the invention to provide a multi-sectioned filter for reducing the level of toxic constituents such as tar, nicotine, carbon monoxide, nitrous oxides and the like that are drawn into the filter during the smoking of a tobacco product.

Problems solved by technology

The long-term harmful effects of tobacco smoke are well known.
Heretofore, none of the aforementioned prior art systems provide a filter for a tobacco smoking product or tobacco smoking article that effectively reduces the level of toxic constituents in the tobacco smoke stream prior to delivery to the smoker.
The prior art also lacks such a filter that incorporates a non-toxic, non-combustible and inorganic material such as calcium hydroxide, or such a filter whose physical characteristics optimizes its filtration action.

Embodiment Construction

[0021] Referring now to drawing FIGS. 1 and 2, which show in a preferred embodiment of the invention a cigarette 10 including a tobacco section 20 and a filter section 30. The tobacco section 20 is typically filled with a smokable material such as tobacco 21. Tipping paper 40 is wrapped around the periphery of the filter section 30 and a portion of the tobacco section 20 to complete the cigarette construction. The tipping paper 40 may be provided with a plurality of holes (not shown) for introducing air into the tobacco smoke stream as the smoke is drawn through the filter section 30. The tobacco section 20 preferably has a length ranging from about 35 mm to about 85 mm, and a circumference of about 17 mm to about 27 mm. Tobacco sections 20 having short lengths (i.e., in a range of about 35 mm to about 50 mm), however, may be employed in accordance with the invention. The filter section 30 preferably has a length ranging from about 15 mm to about 40 mm, and a circumference of about ...

Abstract

A multi-sectioned filter section for reducing the content of toxic constituents contained in a stream of tobacco smoke. The multi-sectioned filter section is composed of at least one non-fibrous section and at least one fibrous plug section. The multi-sectioned filter section is adaptable for use in tobacco products such as cigarettes, cigars, cigarillos and smoking articles such as tobacco pipes and cigarette and cigar holders.

Description

FIELD OF THE INVENTION [0001] The invention relates generally to a multi-sectioned filter for reducing the level of toxic constituents such as tar, nicotine, carbon monoxide, nitrous oxides and the like that are drawn into the filter during the smoking of a tobacco product or tobacco article. DESCRIPTION OF THE RELATED ART [0002] Tobacco smoke is produced during the burning of a tobacco product such as cigarettes, cigars and cigarillos, and a tobacco article such as cigarette and cigar holders, and tobacco pipes. The long-term harmful effects of tobacco smoke are well known. For instance, cigarette smoking is a leading cause of lung cancer, and the leading cause of cancer death in both men and women in the United States. Worldwide, lung cancer kills over one million people each year. Tobacco smoke contains over 60 carcinogens. These chemicals represent approximately 7 chemical classes (polycyclic aromatic hydrocarbons, arenes, N-nitrosamines, aromatic and heterocyclic aromatic amine...
