Description

Tobacco smoke filter {TOBACCO SMOKE FILTER}

The present invention relates to a cigarette smoke filter (for example, for a cigarette) and a method of manufacturing the same.

Worldwide, lulolol acetate is the leading substance used in tobacco smoke filters. For example, it is also known to use paper as filter material in cigarette filters, where paper offers several advantages over cellulose acetate in terms of biodegradability, relatively high filtration efficiency at a given pressure drop, and low material cost . Despite these advantages, the use of paper filters is small and generally limited to niche applications. The main reason that paper filters do not attract broad market interest is that paper filters have the effect of damaging the taste of cigarettes. This so-called 'paper taste' is often thought to impart a more uncomfortable and drier sensation to tobacco smoke.

It is therefore highly desirable to overcome this 'paper taste' and produce a cigarette feel from a paper-filter cigarette that is comparable to the taste of a cigarette using a conventional cellulose acetate filter. In addition, discarded paper butts are degraded much faster than in the case of cellulose acetate, resulting in significant environmental improvements. However, all measures to overcome the paper taste must also bring about a smoking experience comparable to that of a cigarette with a conventional cellulose acetate filter. This has not been achieved with previous attempts to overcome the 'paper taste' defect (eg, the addition of certain spices such as menthol).

Another limitation of the paper filter is the retention of toxic phenolic compounds (for example, phenol, cresol, catechol and resorcinol) found on the volatile and sub-volatile properties of tobacco smoke compared to cellulose acetate filters , Which results in a further increase in the relative yield of phenolic compounds in the case of cigarettes using paper filters. This is due to the well-known selectivity of the cellulose acetate filter for phenolic compounds, rather than the inherent defect of the paper filter. Needless to say, however, it is still necessary to increase the phenolic retention of the paper filter so that the cigarette is not exposed to a high concentration phenolic compound when the cigarette is smoked by the paper filter as compared to the cigarette using the cellulose acetate filter.

Therefore, it is desirable to provide a filter for cigarettes that has no unpleasant paper taste effect and / or has the advantage of a paper filter (biodegradability, etc.) that has a phenolic retention capacity at least comparable to that of a cellulose acetate filter.

It is an object of the present invention to provide such a cigarette smoke filter and a method of manufacturing the same.

According to the present invention there is provided, in a first aspect, a tobacco smoke filtering material comprising paper; And group 21 of the European Union Chemical Groupings List in Annex 1 of the Commission Regulation (EC) No. 1565/2000 and in the EU Spice Information System ("FLAVIS") database A selected one) of a tobacco smoke filter or filter element.

As used herein, the term " anti-enhancement additive "refers to a compound that reduces the unpleasant" paper taste "effect on the taste of a cigarette and / or causes a more unpleasant and drier sensory smoker's perception compared to a cigarette with a known cellulose acetate filter ≪ / RTI > That is, the flavor of the cigarettes with the paper filter containing the flavor enhancer additive should be within the typical flavor-per-cigarette flavor range associated with cigarettes using a commercial brand of cellulose acetate filter. Various attempts have been made to classify flavor materials according to their chemical properties and distribute them into groups of structurally related compounds. To this end, the European Union has compiled a list of 34 chemical groups for flavor substances, which are listed in Commission Regulation (EC) No. 1565/2000, Attachment 1 and the EU Spice Information System ("FLAVIS") database. The present invention uses a flavor enhancing additive selected from Group 11 and / or Group 21 of this list.

The flavor enhancing additive may include alicyclic lactones (e.g., alicyclic lactones having 20 or fewer carbon atoms such as C ₃ -C ₂₀ alicyclic lactones); Aromatic lactones (e.g., aromatic lactones having up to 20 carbon atoms such as C ₆ -C ₂₀ aromatic lactones); Aromatic ketones (e.g., aromatic ketones having up to 20 carbon atoms, such as C ₆ -C ₂₀ aromatic ketones), or esters of secondary alcohols or secondary alcohols. The flavor enhancing additive may be a lactone, which is a phthalide such as an alkylphthalide, for example (C ₁ -C ₆ branched or straight chain alkyl) -phthalide. The Association of Manufacturers of Spices and Extracts (FEMA) compiled a list of generally identified safe substances (GRAS) and numbered them individually (known as FEMA GRAS numbers). The flavor enhancing additive preferably has a FEMA GRAS number (numbered). The flavor enhancing additive may be a lactone (Group 11) with a FEMA GRAS number, such as χ-valerolactone (FEMA GRAS number FEMA 3103), χ-hexa lactone (FEMA 2556), δ-hexa lactone (FEMA 3167), χ-heptaractone (FEMA 2539), χ-octaractone (FEMA 2796), δ-octaractone (FEMA 321), 4-hydroxy- (FEMA 3744), 4,4-dibutyl-χ-butyrolactone (FEMA 2372), mint lactone (FEMA 3764), dihydro- mentofurolactone (FEMA 3755) , 3-butylidene phthalide (FEMA 3333), 3-n-butylphthalide (FEMA 3334) and whiskey lactone (FEMA 3803). The flavor enhancing additive may be a cetylnolide. The spice augmenting additive may be added to a portion of the mixture comprising the spice augmenting additive, such as, for example, an essential oil containing a spice augmenting additive (e.g., a plant extract or vegetable oil or a degradation such as seed oil or nut oil) A portion of the unresolved mixture). The mixture comprising the spice augmenting additive (e.g., plant extract or vegetable oil or undecomposed mixture such as seed oil or nuts oil) may comprise one or more spice augmenting additives. For example, the flavor enhancing additive (or additives) may be included in the form of celery seed oil (e.g., aroma oil of celery seeds). The aromatic oil of the celery seeds includes cetainolide and 3-butylphthalide. Although celery seed oil is known as a fragrance for cigarettes, the use of celery seed oil in combination with a paper filter-used cigarette has not been proposed so far. Preferably, the mixture comprising the spice augmenting additive (e.g. plant extract or vegetable oil or undecomposed mixture such as seed oil or nuts oil) is mixed with, for example, Massoia bark oil (FEMA 3747) It has the same FEMA GRAS number.

Preferably, the flavor enhancing additive is present in the filter or filter element in an amount of up to 1% by weight of the paper weight of the filter or filter element.

The tobacco smoke filter element of the present invention may have a length of 5 to 30 mm, for example 6 to 20 mm, or 8 to 15 mm, or 10 to 12 mm.

The paper can be any paper (or any type of paper) conventionally used in a filter or filter element. The paper may be, for example, a filter paper, an aperture paper or a crepe paper. The paper may be in the form of a web of paper, for example, which is laterally gathered and held in the form of a rod. The fibers of the paper web may be 100% natural fibers (e.g., wood pulp), 100% synthetic fibers, or a mixture of the two (in the case of apertured paper, the paper is preferably 100% natural fibers) . When the paper web includes synthetic fibers, a bonding agent (e.g., a plasticizer) may be included to increase the hardness of the finished filter or filter element (rods). The paper may be in the form of a web of lengthwise corrugated and / or fibril-formed paper, for example, as disclosed in patent document GB 2075328, which is laterally gathered and held in the form of a bar . The filter or filter element may be (or may comprise) a rod (e.g., a cylindrical rod) of filtering material (e.g., formed) that includes (e.g. The filter or filter element may comprise a cigarette smoke filtering material comprising paper and one or more additional filtration materials. The filter or filter element is in the form of a coherent web comprising (for example, formed from a material comprising thereof) a paper and a second filtration material, and optionally one or more additional filtration material Tobacco smoke filtering material. The filter or filter element may include (include) a number of sticks (e.g., formed therefrom) that comprise the web to which it is attached. The second and optional additional filtration materials may be selected from, for example, cellulose acetate tow, (additional) paper (e.g., different from other paper in the filter or filter element), natural and / or synthetic fibers, For example, a nonwoven web made of polypropylene or the like.

In one embodiment of the present invention, a cigarette smoke filter (or filter element) comprising a cigarette smoke filtering material comprising paper has the same or similar structure to that of a filter sold under the trademark MYRIA (a product of Filtrona International Limited) And further comprises a flavor enhancer additive. In another embodiment, a cigarette smoke filter (or filter element) comprising a cigarette smoke filtering material comprising paper has the same or similar structure as the filter sold under the trademark PURACEL (a product of Filtrona International Limited) , And a flavor enhancing additive. In another embodiment, a cigarette smoke filter (or filter element) comprising a cigarette smoke filtering material comprising paper has the same or similar structure to that of a filter sold under the trademark CREST (a product of Filtrona International Limited) , And a flavor enhancing additive.

The filter or filter element (rod) may be overwrapped with a wrapping paper, for example a wrapper of breathable paper. The filter or filter element according to the invention can be packaged in a plugwrap of a standard range and can be vented in any conventional manner.

The spice augmenting additive can be located on or in the filter or filter element (e.g., on paper and / or wrapping paper, if present, and / or if present, on or in a second or additional filtration material Lt; / RTI > If more than one spice enhancing additive is present, the additive can be added to the same location (e.g., both / all on paper) or at different locations (one spice augmenting additive on paper, one on additional filtration material, etc.) Can exist.

Surprisingly, the present inventors have surprisingly found that the incorporation of the above-described flavor enhancing additives or additives into the filter or filter element (for example as a flavoring oil of celery seeds (celery seed oil)) or a cigarette with a paper filter ], &Apos; paper taste ' and can provide a cigarette with sensory characteristics similar to that from the cigarette using a cellulose acetate filter.

The filter or filter element may further comprise another additive that selectively reduces one or more phenolic compounds found on the volatile and / or sub-volatile phase of the tobacco smoke. Here, the term " another additive that selectively reduces one or more phenolic compounds found on the volatile and / or quasi-volatile phase of cigarette smoke "refers to one or more of the compounds in smoke (e.g., Quot; means an additive that proportionally reduces the yield of phenolic compounds, such as phenol, cresol, catechol, or a proportionate decrease in one or more of the resorcinols. The filter or filter element may further comprise at least one additive that selectively reduces at least one phenolic compound found on the volatile and / or sub-volatile phase of the tobacco smoke.

Preferably, additional additives that selectively reduce one or more phenolic compounds found on the volatile and / or sub-volatile phases of tobacco smoke include polyethylene glycol (e.g. PEG200, PEG300, PEG400) or methoxypolyethylene glycol (e.g., mPEG350) to be. Preferably, a further additive that selectively reduces one or more phenolic compounds found on the volatile and / or semi-volatile phase of the tobacco smoke is added to the filter or filter element in an amount of less than 20% by weight of the paper in the filter or filter element exist. For example, an additional additive that selectively reduces one or more phenolic compounds may be present in an amount of from 1 to 19% by weight of the paper in the filter or filter element. If there is at least one additional additive in the filter or filter element (an additive that selectively reduces one or more phenolic compounds found on the volatile and / or sub-volatile components of the cigarette smoke), the additional additive (optionally containing one or more phenolic compounds Reducing additive) is preferably less than or equal to 20% by weight of the paper in the filter or filter element.

Additional additives that selectively reduce one or more phenolic compounds can be located on or in the filter or filter element (e.g., paper and / or wrapping paper, and / or a second or additional filtration material, if present) Or may be impregnated therein). If more than one additional additive is present, the additive may be present at the same position (e.g., both / all on paper) or at different locations (one additive on paper, one on additional filter material, etc.) .

The present inventors have found that polyethylene glycol (e.g., PEG 200, PEG 300, and PGE 400) and methoxy-polyethylene glycol (e.g., mPEG 350) are the most effective additives to selectively reduce phenols in tobacco smoke. Surprisingly, the inventors have also found that when these materials are used in combination with paper, a flavor enhancer additive or a filter or filter element containing the above-mentioned additives, the yield of phenolic compounds is comparable to the yield from a conventional cigarette using a cellulose acetate filter, A filter cigarette having more selective filtration than a conventional paper filter cigarette, and a desirable reduction in paper taste.

The filter element according to the invention can be used as a segment of a two-component, three-component or other multi-component (multi-segment) filter. Two component and other multicomponent filters are known in the art.

In one embodiment, the two-component, three-component, or other multi-component filter includes a granular additive (s) such as activated carbon, silica gel, zeolite, ion exchange resin or sepiolite. The granular additive is preferably not included in the filter element of the present invention (i.e., one contained in one of the other segments of the multi-component filter). In one embodiment, the filter element of the present invention forms the mouth end of a two-segment filter, and the tobacco end segment of the dichroic filter comprises a granular additive.

The filter according to the invention can be used in machine-manufactured cigarettes (e.g., in mass produced and packaged). The filter according to the present invention may also be used in combination with individually filtered roll cigarettes (e.g., manually rolled cigarettes) or roll your own or make-your-own products, Lt; / RTI >

In the filter cigarette according to the present invention, the filter of the present invention (or the filter comprising the filter element of the present invention) is coupled to a cigarette packed with one end facing the cigarette. The filter can be, for example, a ring tipping (in a manner such that it is fastened around the immediately adjacent end of the [packed] filter and the rod to expose much of the filter wrapping paper) or full tipping wrap The length and the manner of fastening around the proximal end of the cigarette bar). Any filter or filter cigarette according to the present invention may or may not be vented or may be vented by well known methods such as pre-pierced or breathable plug wraps, and / or the use of laser perforation and tipping packaging of plug wraps have. The final filter cigarette may be in any perimeter range conventionally used in smoking articles (e.g., about 14 mm to about 28 mm perimeter).

The present invention also provides a filter cigarette comprising the tobacco smoke filter or filter element of the present invention as described above.

The filter or filter element according to the invention can be manufactured as a continuous rod, as is well known in the art. The continuous bar is cut to a constant length for subsequent use while being continuously discharged from the outlet of the manufacturing machine. By this cutting, it becomes a separate filter or filter element as defined and described above, each of which is subsequently attached to an individually packed cigarette bar to form a filter cigarette. However, more generally, a continuously discharged rod is first cut to a length of at least two times (usually four times or six times) for subsequent use; If the initial cut is more than four times the length, the latter is continuously cut to twice the length for the filter cigarette assembly, where a double length filter rod is assembled and joined between a pair of packed packed tobacco rods Lt; / RTI > package) and then separated from the center to obtain two individual filter cigarettes.

According to the present invention there is provided a tobacco smoke filter having the advantage of a paper filter that has no unpleasant paper taste effect and / or has a phenolic retention capacity at least comparable to that of the cellulose acetate filter.

Hereinafter, the present invention will be described in detail with reference to examples.

Example  One

A sample paper filter was prepared from a cylindrical bar (15 mm long, 24.50 mm circumference) of paper formed from perforated porous web of 100% wood pulp fibers according to the method presented in patent document GB2075328A.

The paper is formed on a sloping wire machine from fibers having a length of 2.5 to 6 mm, and has 15 to 35 g of finished material (per grate) per square meter (by the method given in GB 2075328). A spice solution comprising a first, flavor enhancing additive in the form of the essential celery seed oil [the undecomposed mixture of the compounds comprising the flavor enhancing additive cetennalide and 3-butylphthalide] Is applied to a finishing paper (before creasing) which proceeds continuously by a conventional method (for example, a printing wheel or the like). Additional additives in the form of polyethylene glycols are applied to the paper by methods well known in the art. Subsequently, a finishing web of paper advancing in the longitudinal direction (with the additives applied) is advanced between the cooperating rolls in the circumferential direction and then successively joined in the lateral direction During the time) is made in the form of rods. The continuously produced rod to be obtained is continuously cut into a predetermined length by a known method to obtain a filter or a filter rod as a product.

A sample cigarette was assembled using the sample filter prepared as described above. The yield of phenol, o-, m- and p-cresol (collectively referred to as mono-hydroxy phenol) was then determined for all samples under ISO smoking conditions. The yield was compared to a control cigarette (which had the same dimensions but contained a conventional cellulose acetate filter) that was smoked under ISO smoking conditions as well.

A sample filter according to the present invention comprising a paper filter was found to selectively reduce phenol; Exposure of the phenolic compounds described above has been found to be comparable to cellulose acetate filter cigarettes.

Example  2

As a result of the taste test (using methods well known in the art), the unpleasant "paper taste" effect on the taste of the cigarette was reduced and further excluded by the inclusion of a flavor enhancer according to one aspect of the present invention.

Sensory testing was carried out by judges consisting of trained professional smokers. A sample of good commercial cigarettes was purchased from a retail store in a lot. The brand provided one piece of cellulose acetate ('monoacetate') filter, hereinafter referred to as the 'control' cigarette ('C').

Filters were removed from the cigarettes of the first group and replaced with machine-made paper filters of equivalent tar retention. These filters are hereinafter referred to as unmodified paper-filter used cigarettes ('P').

The filter was also removed from the second group of cigarettes and replaced with a machine-made paper filter of equivalent tar retention (as in the case of the P group). A metered amount of a spice solution containing a spice enhancing additive (including, for example, a spice augmenting additive in the form of essential celery seed oil) was injected into each paper filter and the cigarette was aged for about 3 to 4 weeks. Such a filter is hereinafter referred to as a modified paper-filter used cigarette ('P +').

Subsequently, a comparative sensory comparison test (known in the art) was performed by the judges. The judges compare the unmodified paper-filter used cigarette ('P') with the monoacetate control ('C'); The modified paper filter ('P +') was compared to 'C'.

Panelists have determined that 'P' is dryer than 'C' and that cigarettes and overall spices are small. This is an expected fact. However, the panelist determined that the characteristics of the 'P +' filter (a filter comprising a flavor enhancing additive according to one aspect of the present invention) fall within the range of variation between normal packs of the 'C' cigarette. That is, the effect of the "paper taste" on the taste of the cigarette was greatly reduced.

Example  3

The smoking article which was heated without burning the cigarette was tested. A metered amount of the spice solution containing the spice augmenting additive (including, for example, the spice augmenting additive in the form of essential celery seed oil) was injected into the cellulose acetate filter of the smoking article which was heated without burning the cigarette.
