Description

The present invention relates to a multi-component filter for tobacco products, as well as to tobacco products containing such a multi-component filter.

Filter cigarettes typically contain a stick of final blend tobacco, which is wrapped in paper, and a cylindrical filter, aligned with the wrapped tobacco stick so that their ends touch, and connected to the same by means of filter paper. Ventilation, in the form of perforations around the circumference, is usually provided along the filter to mix the main stream of smoke, formed during the burning of the wrapped tobacco stick, with the surrounding air.

In conventional filter cigarettes, the filter usually contains a plug of cellulose acetate fibers, which is wrapped in a porous wrapper. However, cigarettes with a multicomponent filter, which contains two or more segments of filter material, are also known for removing particles and gaseous components from tobacco smoke. In order to improve the aroma of the main stream of tobacco smoke produced during the burning of a rolled tobacco stick, it is known to introduce cigarettes with a filter containing aromatic substances. In particular, the inclusion of aromatic substances in the form of plant material, such as leaves, seeds or roots of one or more aromatic plants, is suggested. In one known example, a multi-component filter cigarette is proposed which has a flavor release segment containing a mixture of herbal materials including licorice, ginger root and shredded peppermint leaf.

Also, the inclusion of tobacco material in the filter of the tobacco product is known. For example, WO-A-2006/090290 discloses a filter containing tobacco grains. Optionally, the tobacco beans may contain aromatic substances.

It would be desirable to provide a multi-component filter for tobacco products which, when used, ensures an improvement of the aroma, and in particular an improved release of the aroma of mint and menthol into the main stream of smoke, when it is withdrawn, by the user, from the tobacco stick through the filter. In addition, it would be desirable to provide a multi-component filter for tobacco products, containing an aroma release segment that minimizes aroma loss during storage.

In accordance with the present invention, there is provided a multi-component filter for tobacco products comprising: a mouth piece, and a flavor release segment upstream of the mouth piece. The aroma release segment comprises a plug of fibrous filter material, a peppermint leaf disposed along the fibrous filter material, and a filter plasticizer applied to the fibrous filter material. The weight share of plasticizers in the flavor release segment is up to 5% of the fibrous filter material.

In accordance with the invention, there is also provided a tobacco product comprising a wrapped stick of tobacco material and a multi-component filter, in accordance with the present invention, connected to the stick of tobacco material, preferably by filter paper. It is preferable to give the tobacco product cigarettes with a filter.

In this specification, the terms "upstream" and "downstream" are used to describe the relative position of the segments of the multicomponent filter of the invention, relative to the direction of the main stream of smoke drawn from the tobacco stick through the multicomponent filter during use. For example, in the filter of the present invention, the flavor release segment is located upstream of the mouthpiece, which means that the main stream of smoke is drawn first through the flavor release segment and then through the mouthpiece.

The term "filter plasticizer" refers to any ingredient suitable for use as a plasticizer in conventional fiber cigarette filters. In conventional fiber filters, the role of the filter plasticizer is to bind the filter fibers together, thus increasing the strength of the filter and therefore its resistance to compression. A plasticizer is usually a solvent for the fibrous material that acts to soften the outer surface of the fibers causing them to bond together. Glycerol triacetate is commonly used as a filter plasticizer with cellulose acetate fibers.

Preferably, the filter plasticizer used in the present invention is glycerol triacetate.

The term "peppermint leaf" is used to denote a material consisting of the leaves of the peppermint plant that have been cut or shredded to obtain the desired material.

A peppermint leaf can release aroma into the main stream of smoke that is pulled through the multi-component filter. The aroma emitted from peppermint leaves is provided by volatile substances, such as the oils contained in them, which evaporate during tasting. The main stream of smoke enriched with peppermint leaf oils passes downstream through the mouthpiece portion of the multi-component filter and enters the consumer's mouth.

Before use, the volatile oils remain trapped in the peppermint leaf. This advantageously ensures the minimization of aroma loss during storage of multi-component filters and tobacco products according to the present invention, while at the same time maximizing the release of aroma into the main stream of smoke during smoking.

Preferably, the peppermint leaf in the flavor release segment has been chopped, cut, or otherwise reduced in size. Even more preferably, the peppermint leaf is cut approximately between 0.25 mm and 3 mm wide. And it is most preferable if the peppermint leaf is cut approximately to a width between 1 mm and 2 mm.

It is preferable that the peppermint leaf is dried so that the moisture content is approximately between 8 and 10%.

It is preferable that the mass fraction of oil in the peppermint leaf is at least 0.6%. Inserting a peppermint leaf into the aroma release segment of multi-component filters in accordance with the present invention advantageously provides an improved method of releasing mint and menthol aroma into the main stream of tobacco product smoke. Tobacco products according to the present invention advantageously provide an improved mint and menthol flavor compared to conventional menthol cigarettes.

In a particularly preferred solution of the invention, the filter plasticizer is glycerol triacetate. Unexpectedly, it was found that the introduction of peppermint leaf and glycerol triacetate into the aroma release segment of multi-component filters and tobacco products according to the present invention, usefully improves the mint and menthol aroma obtained by releasing menthol and other volatile oils from the peppermint leaf. This is illustrated, for example, by the results shown in Table 1.

Table 1 shows the content of individual flavoring components released into the main stream of peppermint leaf smoke in the flavor release segment of filter cigarettes (samples 1 and 3), in accordance with the invention, having the construction shown in drawing 1. The flavor release segment consists of a cellulose acetate fiber plug in which peppermint leaf and glycerol triacetate are arranged. Table 1 also shows the content of the individual flavor components released into the main stream of peppermint leaf smoke in the flavor release segment of filter cigarettes (samples 2 and 4), which are not in accordance with the invention, and have the same construction as samples 1 and 3, except that the flavor release segment does not contain glyceryl triacetate. Each sample contains 40 mg of peppermint leaves. Not all components released from peppermint leaves have been measured.

Each of the samples was tested according to ISO conditions, and the samples of the obtained smoke were analyzed using the GC-MS method of single ion monitoring, in order to determine the content of volatile components in the smoke. A full scan analysis was performed with a scan range of 30 to 400 m/z (anion mass to fill mass).

As can be seen from Table 1, the combination of glycerol triacetate and peppermint leaf in the flavor release segment of a filter cigarette according to the present invention results in an increased level of flavor components released from the peppermint leaf into the mainstream smoke, compared to filter cigarettes not in accordance with the invention, whose flavor release segment does not contain glycerol triacetate.

During consumption of a tobacco product containing a multicomponent filter according to the invention, where the filter plasticizer is glycerol triacetate, acetic acid and glycerin are released in the flavor release segment as a result of the hydrolysis of glycerol triacetate. Therefore, the amount of acetic acid released in the filter during smoking is significantly higher than in tobacco products not in accordance with the invention, which is illustrated by the results shown in Table 2. Table 2 shows the dimensions and characteristics of a filter cigarette (sample 5) according to the present invention, having the construction shown in Figure 9. aroma consists of a cap made of cellulose acetate fibers in which peppermint leaf and glycerol triacetate are arranged. Also, Table 2 shows the dimensions and characteristics of a filter cigarette (sample 6), which is not in accordance with the subject invention, and has the same construction as sample 5, with the fact that the flavor release segment does not contain glycerol triacetate.

As can be seen from Table 2, the combination of glycerol triacetate and peppermint leaf in the flavor release segment of a multi-component filter cigarette according to the present invention (Sample 5) results in a significantly increased level of acetic acid released in the filter, compared to filter cigarettes not according to the present invention (Sample 6) in which only the mouth portion contains glycerol triacetate.

Preferably, the overall length of the tobacco products according to the present invention is approximately between 70 mm and 128 mm, and more preferably about 84 mm.

Preferably, the outer diameter of the multi-component filters and tobacco products according to the present invention is approximately between 5 mm and 8.5 mm, and more preferably around 7.9 mm.

Preferably, the total length of the multi-component filters according to the present invention is approximately between 18 mm and 36 mm, and more preferably about 27 mm.

Preferably, the length of each individual segment of the multicomponent filters according to the present invention is approximately between 5 mm and 22 mm.

The part of the multi-component filters, in accordance with the present invention, which is placed in the mouth can in some solutions prevent the peppermint leaf from the flavor release segment from reaching the mouth of the consumer during smoking. It is preferable that the part that is placed in the mouth contains a filter material. Even more preferably, the mouthpiece contains a filter material that has no solid phase filtering capability or has very low solid phase filtering efficiency. The part that is placed in the mouth may for example contain cellulosic material such as cellulose acetate fibers or fibers of some other suitable filtering material of low filtering efficiency.

When the mouth piece contains a filtering material, it is preferred that the length of the mouth piece is approximately between 3 mm and 12 mm, and more preferably approximately between 6 mm and 8 mm.

In addition, a multi-component filter according to the present invention may include an outermost rod segment upstream of the aroma release segment. Preferably, the end segment of the wand contains a fibrous filter material. For example, the end segment of the rod may comprise a cellulosic material, such as cellulose acetate fibers or some other suitable fibrous filter material, such as paper. The inclusion of an end segment of the rod containing the filter material advantageously provides additional filtration efficiency.

Alternatively, or additionally, the end segment of the wand may contain at least one sorbent capable of removing at least one gas phase constituent from the main stream of smoke drawn through the filter. It is preferable that the sorbent is selected from the group consisting of: activated carbon, activated aluminum, zeolites, sepiolites, molecular sieves and silica gel.

The end segment of the stick may contain one or more flavoring substances, preferably one or more liquid flavoring substances to further enhance the flavor provided to the consumer during smoking.

For example, the end segment of the stick may contain a plug of filter material containing one or more threads impregnated with a liquid aromatic substance. One or more threads may be made of cellulose acetate, rayon, cotton, or some other hydrophilic textile or non-textile material capable of absorbing or adsorbing the liquid aromatic substance. Threads can be colored to indicate, for example, the type of aromatic substance with which they are impregnated. If more than one thread is provided, the threads may be of the same or different colors and may be impregnated with the same or different liquid aromatic substance. Preferably, the thread diameter is approximately between 0.6 mm and 2 mm, and more preferably around 0.8 mm. Filter plugs containing threads impregnated with an aromatic substance, suitable for use in the rod end segments of multicomponent filters in accordance with the invention, as well as methods and apparatus for the manufacture of such plugs, are described in US patents 4,281,671 and 7,074,170 owned by American Filtrona Companv, Richmond, Virginia, USA.

Alternatively, the end segment of the stick can contain a larger number of grains impregnated with a liquid aromatic substance. The grains can be formed from, for example, cellulosic material combined with polyvinyl acetate, or from tobacco powder combined with microcrystalline cellulose. Beads suitable for use in the end segment of multicomponent filter rods in accordance with the present invention are manufactured and sold under the name Viscopearls by Rengo Co. Ltd, Japan. The method and apparatus for producing such grains is described in Japanese patent application no. 10182842. Beads can have the same or different diameter as well as color. The color of the grains can, for example, indicate the type of aromatic substance with which they are impregnated. Preferably, the grain diameter is approximately between 0.2 mm and 2 mm.

The liquid aromatic substances used in the end segment of the multi-component filter rod according to the present invention contain one or more aromatic components to create a certain type of aroma, and they can be natural extracts, artificial aromas or a combination thereof. Liquid aromatic substances and types of aroma that can be used in the end segment of the multi-component filter stick according to the present invention can be: menthol, peppermint, spearmint, coffee, tea, spices (such as cinnamon, garlic and ginger), cocoa, vanilla and fruit aromas, and other substances can be used. In a preferred solution of the present invention, the multi-component filter contains liquid menthol aroma. In such a solution, the addition of menthol aroma to the end segment of the stick enhances the aroma released into the main stream of smoke, which is pulled through the filter during smoking, and complements the menthol and peppermint aromas released downstream into the main stream of smoke by the peppermint leaves in the aroma release segment.

The part that is placed in the mouth can contain at least one flavoring substance, such as those previously described for the end segment of the stick. It is preferable, if aromatic substances are provided, that the part that is placed in the mouth contains one or more threads impregnated with a liquid aromatic substance.

A multi-component filter according to the present invention may include a part that is placed in the mouth containing at least one aromatic substance or an end segment of the stick that contains at least one aromatic substance or a part that is placed in the mouth that contains at least one aromatic substance and an end segment of the stick that contains at least one aromatic substance. When the mouthpiece and the end segment of the stick contain at least one flavoring substance, the flavoring substance in the mouthpiece may be the same or different from the flavoring substance in the end segment of the stick.

In use, when the tobacco smoke is drawn from the tobacco material stick through the multi-component filter, the aroma is released into the main smoke stream from the peppermint leaf in the aroma release segment. In embodiments of the present invention in which at least one flavoring substance is provided in the end segment of the stick, the flavoring is also released upstream of the flavoring release segment, as previously described. In embodiments of the present invention wherein at least one flavoring substance is alternatively or additionally provided in the mouthpiece, the flavoring is also released downstream of the flavoring release segment. Therefore, multi-component filters in accordance with the present invention can provide a double and triple enhancement of the aroma in the main stream of smoke drawn through the filter during smoking.

Multicomponent filters according to the present invention can be made by forming separate continuous rods containing multiple units of each individual segment of the multicomponent filter, and then combining these separate rods in a known manner, in one or more stages, to form a continuous filter rod containing multiple units of the multicomponent filter. The continuous filter rod can then be successively cut at regular intervals, by means of a cutting mechanism, to produce a series of discrete multi-component filters in accordance with the invention.

It is desirable that the tobacco products according to the present invention contain a rolled patch of the final tobacco mixture.

It is desirable that the tobacco products according to the present invention have a total amount of dry particles without nicotine (NFDPM - Nicotine Free Dry Particulate Matter) or an amount of released tar not exceeding approximately 10 mg. More preferably, the amount of tar released is between 1 and 10 mg, and more preferably about 6 mg.

Tobacco products according to the present invention can be packaged in containers, for example soft packs or packs with a hinged lid, with an inner lining impregnated with one or more aromatic substances.

In the filter of the present invention, the peppermint leaf in the flavor release segment is arranged in a plug made of fibrous filter material, preferably cellulose acetate fibers. The filter plasticizer is applied to the fibrous filter material in the standard way, by spraying it onto the individual fibers, preferably before applying the peppermint leaf to the filter material.

It is desirable that the peppermint leaf is predominantly evenly distributed along the plug of fibrous filter material. Preferably, the amount of peppermint leaf in the flavor release segment is approximately between 1 mg and 4 mg per mm of flavor release segment, for a multi-component filter having a diameter of approximately between 7.5 mm and 7.8 mm.

The amount of filter plasticizer may be between 1% and 9% by weight of the fibrous filter material plug, preferably 5% or less. If glycerol triacetate is used as a filter plasticizer, it is preferable that the amount of glycerol triacetate is approximately 5% of the mass of cellulose acetate fibers or other fibrous filter material. This amount of glycerol triacetate was found to provide acceptable strength to the fibrous filter material plug of the aroma release segment without blocking the release of aroma from the peppermint leaf. This amount is significantly less than the amount of glycerol triacetate in conventional cellulose acetate fiber plugs, where it is typically 7% by weight.

In tobacco products according to the present invention, the length of the flavoring segment is approximately between 5 mm and 22 mm, more preferably approximately between 10 mm and 15 mm, and most preferably approximately 12 mm.

In tobacco products according to the present invention, the mouth piece may comprise a hollow tube or cavity. A hollow tube or cavity may be formed when a multi-component filter is joined to a tobacco stick using, for example, filter paper to form a tobacco product according to the present invention. In such tobacco products, the downstream portion of the flavor release segment is visible in the portion of the multicomponent filter that is placed in the mouth, through a hollow tube or cavity, which allows the consumer to see a peppermint leaf, arranged in a plug of fibrous filter material. When the mouthpiece comprises a hollow tube or cavity, it is preferred that the length of the mouthpiece be approximately between 3 mm and 4 mm.

In addition, the multi-component filters according to the present invention may contain a second flavor release segment, between the mouth piece and the flavor release segment, which was previously described. The inclusion of a second aroma release segment further enriches the aroma delivered to the consumer during smoking.

Preferably, the second flavor release segment contains a tobacco leaf. The tobacco leaf may be torn, cut or otherwise reduced in size. It is preferable that the tobacco leaf is finely cut, and it is even more preferable that the tobacco leaf is cut to a width of approximately 0.4 mm.

It is preferable that the tobacco leaf in the second segment is dried to release the aroma. Preferably, the mass fraction of moisture in the tobacco leaf is approximately 15% or less.

Preferably, the length of the second flavor release segment is approximately between 6 mm and 12 mm, more preferably between 6 mm and 10 mm.

The second flavor release segment may comprise a tobacco leaf to which a coating containing, for example, sugars or humectants has been applied.
