Benefits of technology

"The patent text describes the use of a metal granulate, specifically copper, zinc, or a copper-zinc alloy, as a filtering agent for tobacco smoke. The metal granulate is able to effectively bind to a variety of substances, including heavy metals and toxic agents, reducing their content in tobacco products. The metal granulate can be dispersed throughout a fibrous filter or affixed to the tobacco body. The technical effect of this invention is to provide a more effective and efficient way to filter tobacco smoke, improving the safety and quality of smoking devices."

Problems solved by technology

Technological progress in the world today has brought with it accompanying social and environmental problems.
Among the latter, air pollution is dominant.
Smoking constitutes another, albeit self-imposed, air pollution risk.

examples

[0046] An example is given below, which illustrates an embodiment of the invention as a tobacco smoke filter. This example is present to exemplify the invention; they are not, however, intended to limit in any way the invention as covered by the claims.

[0047] The experimental setup is shown in FIGS. 1 and 2. In FIG. Cigarettes 1 were smoked using a plastic tube 4 connected to the cigarettes 1 through a sleeve 2. A common filter only (in cigarette 1) was used as a control, as shown in FIG. 1. A test setup furthermore comprised a copper-zinc alloy (RAM) filter 5. The smoke was guided through the common filter of the cigarette and, when included, the RAM filter 5, and further through a test filter 4. Test filter 4 was weighed before and after smoking. The approximate amount of tar was calculated by the difference of filter weight before and after smoking. The results showed that the amount of tar inhaled from smoking one cigarette was reduced by 45%, when using a RAM filter with a gra...

Abstract

The invention relates to a tobacco smoke filter (40) affixed to a body of tobacco in a smokable device, such as a cigarette. The tobacco smoke filter comprises a metal granulate (42) including zinc or copper, and preferably a copper-zinc alloy. The metal granulate may be disposed between the body of tobacco and a fibrous filter (41), or be dispersed in the fibrous filter.

Description

FIELD OF INVENTION [0001] The invention relates to a tobacco smoke filter for use with smokable devices, such as cigarettes. The tobacco smoke filter comprises a metal granulate including zinc or copper, preferably a granulate of a copper-zinc alloy. BACKGROUND OF THE INVENTION [0002] Technological progress in the world today has brought with it accompanying social and environmental problems. Among the latter, air pollution is dominant. Efforts are presently being made to elevate air fouling problems stemming from sources including industrial and engineering production, and exhaust from motorised vehicles. Stricter regulatory controls and laws have been imposed in order to safeguard society's health and the environment. The International Agency for Research on Cancer (IARC) currently lists 88 individual chemical agents as “Group 1 Human Carcinogens” (IARC monographs, Vols. 1-82, 1987) A substantial number of these agents exist in polluted air, which highlight the urgency for solving...
