Definitions
- the present invention relates to a cigarette filter and a filter-tipped cigarette, and more specifically, to a cigarette filter that can efficiently filter the tobacco mainstream smoke when the cigarette is smoked, improving the tobacco taste, as well as a cigarette having such a filter.
- 44-29317 discloses a tobacco filter prepared by adding specified amounts of charcoal and polyalkylene glycol to a cellulose acetate fiber tow.
- Jpn. Pat. Appln. KOKOKU Publication No. 46-12957 discloses a tobacco filter prepared by adding various oils/fats and a sorbitan derivative to a filter material.
- charcoal is effective means to increase the filtration efficiency for the vapor phase components of the tobacco mainstream smoke.
- the fine pores of charcoal are clogged with tar contained in the tobacco mainstream smoke, and the charcoal loses its absorption activity.
- the filtration efficiency for the vapor phase components in the mainstream smoke while one cigarette is smoked decreases with time from the initial stage of the smoking to the final stage.
- the taste of the tobacco is degraded by the smell of the charcoal. Further, such measures are economically disadvantageous.
- an object of the present invention is to provide a cigarette filter that can efficiently filtrate the tobacco mainstream smoke for each component of the smoke.
- the inventors of the present invention have carried out intensive studies in which cigarettes were manufactured using filters to which various additives were added respectively, and the mainstream smoke of each cigarette was analyzed before and after passing the filter. From the results, it has been found that the filtrated components of the tobacco mainstream smoke were significantly different from one cigarette to another depending on the type of additive used.
- filters added with liquid fatty acids having a low viscosity i.e., a viscosity of 1 to 300 cP (e.g., lauric acid, oleic acid, linoleic acid and linolenic acid) are effective for the filtration of the entire tobacco mainstream smoke
- filters added with liquid fatty acid esters having a low viscosity i.e., a viscosity of 1 to 300 cP
- filters added with liquid fatty acid esters having a low viscosity i.e., a viscosity of 1 to 300 cP
- natural fats/oils such as olive oil, castor oil, rapeseed oil, corn oil, safflower oil and grape seed oil
- filters added with glycols having a low viscosity i.e., a viscosity of 1 to 300 cP (such as polyethyleneglycol and propylenegly
- the vapor pressure of the components in the tobacco mainstream smoke that are absorbed by these additives is 1 to 4000 Pa, whereas the vapor pressure of the components in the tobacco mainstream smoke that are adsorbed by charcoal is 100 to 100,000 Pa, thus indicating a significant difference between the former and the latter.
- the tobacco filter is divided into two or more sections and different types of additives (mainstream smoke component-removing agents) are added to respective sections.
- mainstream smoke component-removing agents mainstream smoke component-removing agents
- a cigarette filter comprising two or more filter sections of the following three filter sections (A) to (C):
- the use of olive oil as the additive improves the flavor of the tobacco smoke, which is preferable.
- the use of propylene glycol as the glycol improves the filtration efficiency for, especially, the high polarity components in the tobacco mainstream smoke.
- the filter section (C) be provided on a downstream side of the filter section (A) and/or filter section (B).
- the cigarette filter of the present invention may include a plain filter section at the most downstream position.
- a cigarette having a filter of the present invention provided at one end of a tobacco rod.
- the upstream and downstream are based on the flowing direction of the mainstream smoke when the cigarette is smoked.
- the tobacco rod side is an upstream side and the mouthend side is a downstream side.
- FIGURE is a partially developed perspective view of a filter-tipped cigarette according to an embodiment of the present invention.
- FIGURE is a partially developed perspective view of a filter-tipped cigarette according to an embodiment of the present invention.
- the FIGURE should be interpreted as also showing a cigarette filter according to an embodiment of the present invention.
- a filter-tipped cigarette 10 shown in the FIGURE comprises a tobacco rod 20 including an ordinary tobacco filler material 201 such as cut tobacco and a tobacco wrapper paper sheet 202, and a filter 30 attached to an end of the tobacco rod 20.
- the structure of the portion other than the filter portion is similar to that of an ordinary filter-tipped cigarette. Therefore, an ordinary tobacco rod can be employed as the tobacco rod 20.
- the filter comprises two or more filter sections of the following filter sections: (A) a filter section added with a liquid fatty acid ester or a liquid fatty acid, having a viscosity of 1 to 300 cP as a mainstream smoke component-removing agent; (B) a filter section added with a glycol having a viscosity of 1 to 300 cP as a mainstream smoke component-removing agent; and (C) a filter section added with a charcoal as a mainstream smoke component-removing agent.
- A a filter section added with a liquid fatty acid ester or a liquid fatty acid, having a viscosity of 1 to 300 cP as a mainstream smoke component-removing agent
- B a filter section added with a glycol having a viscosity of 1 to 300 cP as a mainstream smoke component-removing agent
- C a filter section added with a charcoal as a mainstream smoke component-removing agent.
- liquid fatty acid ester added to the filter section (A) examples include natural fats/oils such as olive oil, castor oil, rapeseed oil, corn oil, safflower oil and grape seed oil.
- liquid fatty acid added to the filter section (A) examples include lauric acid, oleic acid, linoleic acid and linolenic acid.
- a preferable example of the mainstream smoke component-removing agent added to the filter section (A) is olive oil.
- the flavor of olive oil matches well with the flavor of tobacco.
- the amount of liquid fatty acid ester or fatty acid added is preferably 5% to 30% of the weight of the filter fibers.
- glycols having a viscosity of 1 cP to 300 cP added to the filter section (B) are polyethylene glycol and propylene glycol. Of these, propylene glycol is preferable.
- the amount of glycol added is preferably 5% to 30% of the weight of the filter fibers.
- charcoal added to the filter section (C) is charcoal used for an ordinary so-called charcoal filter, such as coconut shell charcoal.
- the amount of charcoal added is preferably 10 to 80 mg per 10 mm length of filter (circumference of filter 16.8 mm to 25.8 mm).
- the filter 30 includes, e.g., four discrete filter sections, that is, from the upstream side, a first filter section 301, a second filter section 302, a third filter section 303 and a fourth filter section 304.
- the first filter section 301 provided in contact with the tobacco rod 20 is constituted by the above-described filter section (A)
- the second filter section 302 is constituted by the above-described filter section (B)
- the third filter section 303 is constituted by the above-described filter section (C).
- the fourth filter section 304 located at the most downstream side is constituted by a plain filter intended to prevent the falling off of the charcoal in the third filter section 303 constituted by the above-described filter section (C).
- the plain filter does not contain any additive to remove the mainstream smoke, and it is made of substantially a filter material.
- Each of the first to the fourth filter sections 301 to 304 is formed from a filter material used in ordinary cigarette filters, for example, paper, or a tow of synthetic fibers such as cellulose rayon fibers, cellulose acetate fibers or vinylon fibers.
- a filter material used in ordinary cigarette filters for example, paper, or a tow of synthetic fibers such as cellulose rayon fibers, cellulose acetate fibers or vinylon fibers.
- the mainstream smoke component-removing agents for the filter sections 301 and 302 can be added thereto by spraying or coating them to the respective filter materials.
- the charcoal used in the third filter section can be added thereto by dispersedly mixing it into the filter material by an ordinary method.
- any one of the filter sections 301 to 303 can be omitted from the structure of the filter according to the preferred embodiment. Further, the filter section 304 can be omitted as well.
- the cigarette filter of the present invention most preferably has the filter section (C) on the downstream side of the filter sections (A) and/or (B). With this stricture, the filtration efficiency is improved in a synergetic manner. Further, when the filter section (C) is placed on the downstream side, the decrease with time in the filtration efficiency of the charcoal for the tobacco mainstream smoke can be suppressed.
- each of the first to the fourth filter sections 301 to 304 is individually wrapped with a respective filter wrapper paper sheet (not shown) as required, and then they are wrapped with one wrapper paper sheet 310 to integrate them together.
- the thus formed filter 30 is attached to one end of the tobacco rod 20 by an ordinary tipping paper 320.
- the filtration efficiency for the mainstream smoke components was evaluated for each of cigarette filters to which olive oil, propylene glycol and linoleic acid (each available from Wako Pure Chemical Industries, Ltd.) were added respectively as the mainstream smoke component-removing agent.
- a plasticizer-free cellulose acetate filter (3Y/43000) was used for each case.
- the mainstream smoke component-removing agent was sprayed in the form of fine particles onto the cigarette filter in amount of 35 mg, using an atomizer.
- the tobacco rod that of Mild Seven Super Light available from Japan Tobacco Inc. was used.
- the filter added with the respective mainstream smoke component-removing agent was attached to the tobacco rod with an adhesive tape, providing a sample cigarette.
- the calculated value for the combination of the charcoal filter section with the olive oil-added filter section is a simply calculated value based on each of the filter sections used singly.
- the comparison between the calculated values and the found values indicates that the filtration efficiency does not show a significant difference for the high boiling point components, but is significantly higher in the found values for the low boiling point components. From the results, it is seen that when a filter section added with charcoal as a mainstream smoke component-removing agent is combined, on the downstream side, with another filter section added with another mainstream smoke component-removing agent, a more excellent effect (synergetic effect) can be obtained as compared to the total effects obtained when the filter sections are used singly.
- a cigarette filter that can efficiently filtrate the tobacco mainstream smoke for each component thereof, and a filter-tipped cigarette comprising such a filter.
