Benefits of technology

[0019] It is the main object of the present invention to improve the efficiency of tobacco smoke cleaning.
[0020] It is another object of the invention to provide variable efficiency of tobacco smoke cleaning.

Problems solved by technology

Tobacco smoke is known to contain toxic and mutagenic compounds leading to various smokers' diseases.
However, such filters are able only to reduce partially the amount of toxic and mutagenic compounds entering the smoker's body.
Besides, conventional filters disadvantageously result in removal of aromatic compounds, thereby making such cigarettes less attractive for smokers.
The above referenced filter for a tobacco product has a limited functionality since the efficiency of tobacco smoke cleaning remains practically at the level achieved with the use of a conventional tobacco filter.
The disadvantage of the prior art solution consists in actually non-controllable time change of the efficiency of tobacco smoke cleaning (dilution) as the tobacco product is consumed by the smoker, which is caused by a continuous drop in resistance to the flow of tobacco smoke owing to thermal decomposition (“smoking”) of the tobacco core, resulting in shortening of the same (and consequently drop in dynamic resistance to the flow of tobacco smoke passing through the tobacco core), with the resistance to the air flow through the perforation of the filter air ventilation remaining unchanged.
Since a single capsule with water is used in the above described filter, it appears impossible either to vary the efficiency of tobacco smoke cleaning or to aromatize tobacco smoke.

example 1

[0097] Forty cigarettes were used manufactured according to ISO 3402 (cigarette weight 874±20 mg). Twenty cigarettes were kept as a reference batch, and two ampoule-type capsules in the form of a globe were put in each of the remaining twenty cigarettes. Thereafter, each cigarette was weighed again. Said first ampoule-type capsule had a casing made of aluminum foil, and said second ampoule-type capsule had silver foil casing. A double-sided notching was provided on the inner and the outer sides of both ampoule-type capsules. In said first capsule a rectangular notching was provided with the surface area of 1 mm 2, and a M-shaped notching was provided in said second capsule, with the surface area of 1.5 mm 2. A first filtering member in the thus modified filter amounted to about 29% of its initial volume as determined by individual weighing of the filtering material filaments removed by mechanical micromilling, with said filaments having the weight of 56 to 60 mg.

[0103] Thirty cigarettes were used, ten of which were kept as a control batch.

[0104] Ten cigarettes of the first batch were brought to conformity with the inventive filter design shown in FIG. 1, and the remaining ten cigarettes of the second batch were brought to conformity with the filter design shown in FIG. 2.

[0105] Cigarettes of the first batch were provided with a tubular capsule containing 40 percent by volume of a liquid flavoring agent in the form of a 60% ethanol-based extract containing fennel oil, said capsule being mounted in the porous filtering member on the part of the filter end abutting on the tobacco core. An ampoule-type capsule containing 98 percent by volume of deionized water was placed in the porous filtering member on the part of the mouthpiece. A waterproof paper impregnated from the inside with a thin layer of paraffin refined wax was used as the filter casing.

[0106] Cigarettes of the second batch were provided with an ampoule-type capsule containing 98...

example 3

[0116] Seventy filter-tipped cigarettes were used, having the porous filtering member in the form of acetate fiber tow and provided with a plastic mouthpiece. Ten cigarettes of the said seventy cigarettes were kept as a control batch.

[0117] The ratio of 1:3 was established between tubular and ampoule-type capsules. The remaining sixty cigarettes were divided into the first batch (30 cigarettes) and the second batch (30 cigarettes).

[0118] Cigarettes of the first batch were provided with a tubular capsule containing a flavoring agent in the form of a gas-vapor composition comprising 40% of eucalyptus ester in freon gas, said capsule being mounted in the porous filtering member on the part of the filter end abutting on the tobacco core. Then, an axial recess was made in the porous filtering member on the mouthpiece part, wherein three ampoule-type capsules were placed one after another. The relative volume change between said capsules was adjusted based on the following ratio: 70%: 2...

Abstract

A filter-tipped cigarette comprises tobacco core 1 contained in casing 3, and filter 2, the filter having first filtering member 4 connected by its one end to tobacco core 1, and a second filtering member provided within first filtering member 4. The second filtering member comprises a distributed system of water-resistant casings having a liquid nucleus, the casings being in the form of tubular capsules 6 and / or ampoule-type capsules 7, which capsules 6, 7 are caused to rupture upon mechanical force is exerted externally thereon. The second filtering member has a volume within the range from 3 to 75 percent by volume of the volume of the first filtering member. The filter-tipped cigarette provides high-quality tobacco smoke cleaning along with enabling the smoker to vary the efficiency of tobacco smoke cleaning and simultaneously flavor tobacco smoke.

Description

RELATED APPLICATIONS [0001] This application claims priority to Eurasian patent application number EA 200501915 / 26, filed Nov. 29, 2005, which is incorporated herein by reference in its entirety. FIELD OF THE INVENTION [0002] The present invention relates to the field of tobacco industry, particularly, to a filter-tipped cigarette. [0003] The present invention is suitable for production of filter-tipped cigarettes with reduced content of human health-detrimental substances in tobacco smoke. BACKGROUND OF THE INVENTION [0004] Tobacco smoke is known to contain toxic and mutagenic compounds leading to various smokers' diseases. One of the possible ways to lower the content of harmful substances in tobacco smoke entering the respiratory tract of a smoker is to use filters forming part of the cigarette and mounted between the lighted tobacco core and the smoker's oral cavity. [0005] As a rule, cigarette filters are made of acetyl cellulose with activated charcoal added thereto. However, ...
