    description
    The invention relates to a layer composite which encloses the filter attached to a smoking article.
    By the term " smoking article " is meant a cigarette or a cigarillo. The invention is further described with reference to the cigarette application, although it is also applicable to cigarillos provided they are provided with a filter.
    The essential parts of today's filter cigarettes are an approximately circular cylindrical tobacco rod, an approximately circular cylindrical filter, cigarette paper wrapping around the tobacco rod, filter sleeve (often also referred to as "filter wrapper paper") immediately surrounding the filter and tipping paper (also often called " tipping ", " tipping " or " tipping "), which both envelopes the filter wrapper and connects the filter-near portion of the cigarette paper and thus their sheaths tobacco rod and filter together. The tipping paper is that part of the cigarette which, when smoking, is touched directly by the lips of the person smoking the cigarette. Although the term " tipping paper " the word " paper " includes, the tipping paper does not necessarily have to be a real paper. It can also be formed, for example, by a film, for example made of cellulose hydrate, or else by a combination of different layers, which need not necessarily be made of paper.
    It is common to influence the sensations that a person smoking a cigarette has by adding sensory agents to cigarettes. &Quot; sensation substances " in this sense are substances which evoke sensations in the smoking person, such as coldness (freshness) or warmth, or a taste sensation.

    In the specifications EP 1891866 A1, EP 1942753 B1, EP 539009 A2, US Pat. No. 4,643,205 A, WO 2007052170 A2, WO 2008019281 A2 and WO 2010051076 A1, it is proposed to provide the mouthpiece covering paper with a sensation substance, for example to impregnate it with a liquid sensation substance. By touching the tipping paper with the lips one can thus already have a pleasant sensation, for example a taste sensation or a sensation of freshness, even if one does not suck on the cigarette. According to the two last-mentioned WO documents, it is proposed to arrange the sensory-providing mouthpiece covering paper as the third, outermost coating layer around the cigarette filter and to optionally removably fasten this layer to the smoking person.
    In US 4675064 A, it is proposed to form the filter core and a circular cylindrical layer of cellulose acetate directly surrounding it, wherein the material is present in the filter core as fibers and in the enveloping layer as a dense, extruded shell. US 4869275 A proposes the same construction using a plastic instead of cellulose acetate. By using the same material for the core and immediately adjacent jacket of the filter, the manufacturing process becomes cost-effective since waste can be recycled well into the manufacturing process. By forming a rigid shell, the shell itself can be soft and thus made of extremely thin fibers so that it has a high internal surface. By being dense, the jacket prevents the unwanted ingress of substances from the tipping paper. The use of sensory fabrics for the tipping paper is not mentioned. However, the tight sheathing of the filter core has been found to be disadvantageous. Substances such as Triace P.006 / 029 17/09/2012 16:50 17, Sep, 2012 16:44 LAWFIRM 0732 773410 6

Reinforced by the intended particularly large inner surface of the filter core, the volatilization can be done on the faces in the usual and economical production processes only under extreme time, since the existing filter core and immediate sheathing filter blanks are produced with multiple length of a final cigarette filter and their last division cut only in the cigarette manufacturing machine experienced.
    Above all, in order to set smoke levels, the sheaths around the filter are porous, so designed to be permeable to air, so that not only smoke passes through the tobacco rod in the filter and in the mouth of the person smoking the sucking on the cigarette, but also fresh air over the exposed lateral surface area of the tipping paper. Thus, sensory substances contained in the tipping paper or substances which serve as carriers for sensory substances are inhaled together with the smoke coming from the tobacco stream. For this reason, only those sensory fabrics and carriers can be used for this on the tipping paper, which are not harmful or disturbing when inhaled, or interfere with the smoke flow. Furthermore, it is disturbing that sensory fabrics, b2w. their carriers diffuse to a high degree from the tipping paper into the filter bag and into the material of the filter.
    It has been found that sensory fabric applied to a tipping paper is barely effective after processing the sensitized tipping paper in the cigarette manufacturing machine, for example, scarcely causing a sensation of taste when the mouth is touched / 2012 16:50 No4 / 2 ^ 9 17, Sep. 2012 16:44 LAWFIRM 0732 773410 6

    In the writings CN 201365521 Y and CN 201365522 Y is proposed to form the filter of an inner circular cylindrical part and an outer tubular member and to arrange in the inner circular cylindrical part in the longitudinal direction of the cigarette extending strands of material wetted with sensate material. According to the former of the two cited documents, it is proposed to provide the filter within the abovementioned sheaths with a further coating layer which has air ducts extending in the axial direction of the cigarette from approximately the longitudinal center of the filter to the smoker-side end. The formation of said channels serves to advantageously combine the volume flow which the person smoking from the cigarette draws from a partial stream coming through the tobacco stream and a partial stream coming through the air-permeable coating layers of the filter. All cladding layers of the filter are permeable to air and diffusion of sensory agents.
    The documents US 2755206 A, US 3916914 A, CN 2193654 Y and EP 1895863 Bl describe cigarette filters which have stored sensory substances in liquid form in the filter core, these substances typically being stored in a capsule which can be broken open by an external pressure force, that the substance can come into contact with the smoke stream from the tobacco part of the cigarette and develop its effect. In order for the liquid substance, often an oily substance, not the tipping paper, ie the outer coating layer of the filter of the finished cigarette, to be soaked and discolored, the tipping paper and the filter core containing the liquid substance are separated by a circular cylindrical jacket-shaped intermediate layer of a liquid-tight separating material. Neither the tipping paper nor the contact with the tipping paper 17/09/2012 16:51

    The sensitive portion of the dense layer has a sensory substance such as a sensation-causing substance.
    It has been found that not only sensory substances contained in the filter core can discolor the tipping paper, but also sensory agents mixed with the tobacco. This is typically the case with the so-called Kretek cigarettes, which are particularly widespread in Indonesia. Here, the cigarette tobacco clove meal is added. An oil diffuses out of the clove meal, which subsequently discolors the cigarette paper unattractive.
    EP 1 044 615 B1 deals with the problem that - especially in unfavorable environmental conditions - substances from the tobacco can diffuse into the adjacent cigarette paper and cause visible spots on it. To avoid this, it is proposed to use cigarette paper which is provided with a water-repellent impregnation of the cellulose derivative, in particular ethyl cellulose, wherein cigarette paper and impregnation are adjusted so that the air permeability of the impregnated paper is at least 20 Coresta units.
    By forming cigarette paper according to EP 1 044 615 Bl, it is possible to prevent cigarette paper from being discolored by oil which diffuses away from the clove meal which is mixed with tobacco in Kretek cigarettes. However, it has been found that this oil (and also other oils contained in the tobacco rod), especially during the smoking of a cigarette discolor also the tipping paper ugly.
    The object underlying the invention was to provide a layer composite comprising the tipping paper for the wrapping of the filter part of a cigarette, by P.009 / 029 17/09/2012 16:51 Nr6 / 28gg 7, Sep. 2012 16:45 LAWFIRM 0732 773410 6

For the solution of this problem, it is proposed to use as cover for the filter part of the cigarette a laminate which comprises mouthpiece covering paper and filter wrapping paper as well as a sensory-tight layer, the dense layer being arranged between the tipping paper and the filter wrapping paper.
    The dense layer prevents the oily components of the sensory substances from ever reaching the tipping paper. Nevertheless, a filter paper which is permeable to diffusion can be used, with the disadvantages of dense layers discussed above with reference to US Pat. Nos. 4,674,064 and 4,863,275 as a filter wrapping paper for the manufacturing process of filters are bypassed.
    In the course of further considerations, it has surprisingly been realized that this layer composite provides advantages for the application of sensory substances which are applied to the tipping paper, which are much more valuable than the mere achievement of the originally intended purpose, the discoloring of the tipping paper by oily substances to avoid from the tobacco cord.
    Namely, it is achieved that many restrictions on sensory fabrics applied to or on the tipping paper are overcome. Thus, a wider range of sensory fabrics can be used, larger amounts of Erapfindungsstoffen can be used, there are more combinations of different sensory substances applicable and sensory substances can be used even in such aggregate states in which they were previously unusable. 17/09/2012 16:52

    The outer layer of said layer composite, the tipping paper 5, is in contact with a sensory area 8, 18, 28. This sensory area 8, 18, 28 contains sensory substances as defined above. It can be applied by printing or impregnation on the outside or on the inside of the mouthpiece covering paper. However, it can also be applied as a coating or printing on the outside of the dense layer 6, which is the side of the dense layer 6 facing the tipping material paper. While cigarette paper 3, filter cover 4 and mostly mouthpiece covering paper 5 are intended porous and thus permeable to air and permeable, the material of the dense layer 6 is intended not or hardly permeable to air and hardly or hardly open to diffusion. Sensory fabric is thereby prevented from entering the filter 2 from the sensory area 8, 18, 28 from the tipping paper 5 and from this with the smoke into the lungs of the person smoking.
    So that an air flow from the environment at the smoke flow is at-mingled, which consists of dense layer 6 and tipping paper 5 sub-composite layer composite according to the invention is approximately in the region of the longitudinal center of the filter part of surface areas, which are not provided with sensory material, by a grid of small Breakthroughs 7 perforated. The process of perforating can be done by laser directly on the cigarette machine, the laser already acting on the composite layer of tipping paper and dense layer. (The breakthroughs 7 are usually so fine that you can not or hardly recognize them on the finished cigarette with the naked eye.)
    According to Fig. 1, the sensory fabric area 8 is applied to the outer side of the mouthpiece covering paper 5. Preferably, a different composition and / or a different concentration of sensation substances is applied to the tobacco-strand-side longitudinal half of the tipping paper 5 than to the tobacco rod starting from the tobacco rod

The former longitudinal half is mainly in contact with the fingers of the person smoking and therefore should have a different effect than the second half of the length, which comes mainly in contact with the lips of the person smoking.
    In the examples of FIGS. 2 and 3, the sensory area 18 is attached at the interface between the dense layer 6 and tipping paper 5. In the course of manufacture, it may have been applied either to the dense layer 6 or to the tipping paper 5. Arranging the sensory area 18 at the interface between the dense layer 6 and tipping paper 5 is particularly advantageous over placing it on the outside of the tipping paper because it allows the sensory area 18 to be better protected against mechanical impact. It is thus possible to avoid contact of the sensory area with parts of the cigarette machine and / or with the cigarette packaging machine and / or with other cigarettes and / or with the cigarette packaging. Due to the nature of the sensory substances, the sensory area is often susceptible to abrasion or tends to stick.
    If the tipping paper 5 is not extremely thin and porous, it is advantageous to provide it with a perforation of a grid of fine apertures 5.1 at the surface areas which are in contact with the sensing area 18, so that the sensory fabrics fit well to the the smoking person touched can get surface side. As intended, these openings 5.1 extend only through the tipping paper 5 and in no case through the dense layer 6, since otherwise the effect of the dense layer 6 according to the invention would be lost. Through these apertures 5.1, a per se diffusion-tight film can be used as mouthpiece covering paper 5, even if the sensory-material region 18 is arranged on the inside of the mouthpiece-covering paper. The breakthroughs 5.1 can be so fine 17/09/2012 16:53

    Be designed so that they are not or hardly recognizable with the naked eye.
    On which side of the tipping paper 5 it is more advantageous to apply the sensation cloth, it also depends on the nature of the sensation cloth, in particular on its mobility and on its sensitivity to environmental conditions, e.g. Light, off. On the inside of the tipping paper 5 and on the outside of the dense layer 6, the sensation cloth is better protected from light, in particular, than when it is attached to the outside of the tipping paper 5; but then he is not so quickly and directly touchable and perceptible through the lips of the smoking person.
    Whether it is more advantageous to apply the sensory substance to the inside of the mouthpiece covering paper 5, which is then forcibly porous, or to the outside of the dense layer 6, depends above all on the adhesion properties of the sensation substance b2w. from the entrainment materials containing them as well as the manufacturing conditions for tipping paper and dense coating. By including the consideration that the sensation fabric can be applied not only to the tipping paper 5 but also (instead) to the outside of the dense layer 6, the spectrum of useful senses is broadened. If necessary, 5 sensory fabric can also be applied to both the dense layer 6 and the mouthpiece covering paper. Thus, a larger amount of sensory fabric can be applied and otherwise difficult to mix senses can be combined.
    In the embodiment according to FIG. 3, the length of the dense layer 6 (in the axial direction of the filter cigarette) is shorter than the length of the tipping paper 5, so that it extends essentially only on the sensation area 18 of the tipping paper 5.

    Example 4 illustrates by way of example how a reservoir of sensory substance 18 can be arranged between the dense layer and the mouthpiece covering paper 5.
    On the outside of the dense layer 6, an annular elevation 16 is applied by a structural lacquer, the enclosed volume is filled with sensory material and thus the sensory fabric Fbereich 18 forms. This structure is like the entire dense layer 6 enclosed by mouthpiece covering paper. In over the middle of the region of the sensory fabric 18, the mouthpiece covering paper is provided with an opening 5.1, whose diameter is significantly smaller than the diameter of the annular elevation 16. At the edge of the opening 5.1, the mouthpiece covering paper 5 is provided with an impregnation 15, by the adhesive and firming effect the edge of the opening 5.1 is protected against fraying. In addition, of course, impregnation 15 can also have the function of a further sensory substance and / or optical function. By a reservoir of sensation is stored between the dense layer 6 and the mouthpiece covering paper 5, which communicates only with the outside of the mouthpiece covering paper 5 via a comparatively small opening 5.1, it is possible to accommodate a comparatively very large amount of sensory substance in a well-protected manner and to control it slowly and well be used.
    Instead of limiting the sensory area 18 by an annular elevation of separately applied textured lacquer, one could also form the boundary by creating a localized depression on the dense layer 6 or tipping paper 5, for example by embossing, lasering or grinding. With a matching, not too liquid consistency of the sensory fabric 18 and good bonding between tipping paper 5 and 17/09/2012 16:53

    T 2101 dense layer you need no depression or no separately applied boundary 16.
    In the embodiment according to FIG. 5, the mouthpiece covering paper 5 is provided with apertures 5.2, which are quite macroscopically large. Sensory fabric is applied to the area exposed by the bridge surface areas on the outside of the dense layer 6, which thus form the sensory areas 28. According to the invention, the openings 5.2 are so large that when the cigarette is being consumed, the sensory areas 28 are touched directly by the lips or the fingers of the smoking person. The minimum cross-sectional area of the individual apertures 5.2 should depend on the shape and orientation of the cross-sectional area and on the thickness of the tipping paper. In any case, the cross-sectional area should be at least 1 mm2. By shape and arrangement of the apertures 5.2 and color and application of sensory fabrics can be contributed to the visually appealing design of the cigarette. In this embodiment, crystals of sensational substances may be applied to the sensation area 28, or sensation substances originally applied in liquid form may be allowed to crystallize out there. Because the sensory region 28 is arranged in a depression somewhat protected by the tipping material 5, sensory substances can also be applied thereto in the form of a sensitive layer, for example in the form of flakes, coarser particles or dusts.
    It is also possible to provide the sensory area 28 with such a strong coating of sensation material that this coating is flush with the outside of the mouthpiece covering paper 5 or projects slightly out of it. In these cases, the sensory layer must be at least mechanically strong at least on its outer surface so that it is not damaged during manufacture and packaging of the cigarette. 17/09/2012 16:54

    In the exemplary embodiment according to FIG. 6, the mouthpiece covering paper 5 has apertures 5. 2, which are quite so large that they are visible to the naked eye, for example having a diameter of several mm. At the locations where these breakthroughs lie is the dense layer 6 with a " sealant " markable local coating 9 provided. This coating 9 can typically be a relatively hard wax, on whose outer surface a structure, for example in the form of a logo or a pattern, is embossed. Above all, the lower-lying surface regions of this structure form the sensing material region 28.
    As the material of the dense layer 6 are in principle materials that are easy to produce as thin films.
    It is particularly advantageous to form the dense layer 6 of cellulose hydrate (also referred to as "cellophane" or "cellophane"), since, in addition to good manufacturability as a film, it is also compostable and, in the case of combustion, burns with an approximately identical odor dry wood or paper and also forms about the same combustion products. Another significant advantage of cellulose hydrate is that it is impermeable to liquids but allows water vapor to pass through. This is advantageous for the microclimate in and on the filter. For example, it is achieved that even in extremely unfavorable environmental conditions on the dense layer 6 does not come to the formation of moisture from water vapor condensation.
    The dense layer 6 can also be formed from polylactic acid or from starch. Also from these materials thin films are very easy to produce and the materials are well korapostierbar.
    Likewise, the dense layer 6 may also be formed by a thin metal foil, preferably a thin aluminum foil. Of course, the dense layer 6 may also be formed of a bond formed by bonding of a (thin) film and a (thin) paper layer. P.017 / 029 17/09/2012 16:54 No14 / 28ig 17.

    Cigarette paper 3, filter sleeve 4 and tipping paper 5 are made in the Norraalfall of paper, since thus the desired properties, especially in terms of flammability, processability, porosity and environmental compatibility are easily accessible. Within the concept of the invention, however, materials other than paper can also be used for these coverings.
    In order to make no major adjustments for the production of filter cigarettes according to the invention on cigarette machines, it is advisable to already connect in upstream operations mouthpiece covering paper 5 and dense layer 6 and also the sensory fabric before the mouthpiece covering paper 5 and / or on the outside of the dense layer 6 to install. In addition to the simple operation in the cigarette machine can be achieved with the additional advantage that the sensory fabric does not come into contact with the moisture of that adhesive, which is required for the connection process with the filter wrapper paper. As a result, the disturbing effect described above is avoided, that sensory material which has been applied to tipping paper is hardly effective after the processing of the mouth piece tipping paper in the cigarette machine. This inactivation seems to be caused by the fact that possibly the moisture of the adhesive causes the sensory material of the near-surface areas diffused into deeper areas and thus can no longer be perceived.
    In an advantageous embodiment, the tipping paper 5 of a filter cigarette according to the invention is encased with a user-removable outer covering layer which is typically peelable by releasing a light bond.

By preventing the inner dense layer 6 diffusion of the sensory fabric into the filter, more and different sensory fabric can be applied than if this dense layer 6 were absent. By a removable outer cover layer, which also covers the mouthpiece covering paper 5, further limitation on the type and amount of sensory substances are overcome. For the material of the outer cover layer, especially film materials and diffusion-proof papers are suitable. In particular, the materials are cellulose hydrate, polylactic acid and starch, since the films produced with them are both sufficiently diffusion-tight and readily biodegradable.
