Problems solved by technology

The ring is made of a solid material, preferably metal, which causes considerable staining and does not reliably achieve the desired level of sidestream smoke reduction and extinguishment time due to the variable diameter of the cigarette

Embodiment

[0088] The effectiveness of various embodiments of the present invention in treating sidestream smoke will be demonstrated in the following examples. However, the following examples are given in no way intended to limit the scope of the appended claims thereto.

example 1

[0090] The representative composition of the treatment material may vary to some extent, but its various components are generally within the following ranges.

[0091] Element

example 2

[0093] Several points should be considered with regard to the efficiency of materials for treating sidestream smoke. The visible constituents of the sidestream smoke must be reduced sufficiently for the smoker to appreciate the benefits of smoking the cigarette unit of the present invention. Systems that handle sidestream smoke should not significantly affect the flavor and taste of mainstream smoke. Again, the treatment should not add anything to the mainstream smoke that would significantly affect flavor and taste. The treated material must also be free from any odorous gases.

[0094] To evaluate the reduction in visible sidestream smoke, sample cigarettes were tested against a control (conventional cigarette) to evaluate the reduction in visible sidestream smoke. This test detects visible sidestream smoke and gives a relative value for the smoke emitted by the treatment device of the present invention in terms of the percentage smoke emitted relative to the control.

Abstract

A cigarette sidestream smoke treatment material made from a sheet of non-combustible active ingredients provides a porous structure for sidestream smoke treatment. The treatment material, when used in combination with conventional cigarette paper cigarettes, provides a cigarette unit that delivers low sidestream smoke. The porosity of the material facilitates the normal free burn rate of the cigarette. The material may contain an adsorbent capable of adsorbing sidestream smoke components and an oxygen storage component capable of releasing oxygen at the free burn rate temperature to ensure that the normal free burn rate is maintained and to enhance oxidation of the adsorbed non-water components. Preferably the material includes an oxidation catalyst, preferably the oxygen storage component also has dual functions as an oxidation catalyst. A particularly preferred component that performs a dual function is an oxide of cerium.

Description

field of invention [0001] Cigarette sidestream smoke management material formed from a sheet of non-combustible active ingredient that provides a porous structure for sidestream smoke management. The treatment material, when used in combination with conventional rolling paper cigarettes, provides cigarette units with low sidestream smoke release. The material has a porosity that promotes the normal free burn rate of the cigarette. The material may contain an adsorbent capable of adsorbing sidestream smoke constituents and an oxygen storage component that evolves oxygen at the free burn rate temperature to ensure that the normal free burn rate is maintained and enhances the retention of trapped non-aqueous constituents oxidation treatment. Preferably the material includes an oxidation catalyst, preferably the oxygen storage component also functions dually as an oxidation catalyst. A particularly preferred ingredient that performs a dual function is an oxide of cerium. Back...
