    [0001] The present invention relates to an article for smokers, which comprises a mouthpiece, a capsule containing fluid that can be broken, and a segment of change and color, capable of changing the color. The invention also relates to a mouthpiece for this article for smokers.
    [0002] Some articles for smokers, such as filter cigarettes, typically comprise a cylindrical rod filled with tobacco fragments, surrounded by a paper wrapper and a cylindrical filter axially aligned in a longitudinally adjacent relationship with the tobacco rod involved. Conventionally, the wrapped tobacco rod and the filter are joined by a pointed paper, typically formed by a strip of paper material that surrounds the entire length of the filter and an adjacent part of the wrapped tobacco rod.
    [0003] Several articles for smokers, in which the tobacco is heated, instead of burned, were also proposed in the technique. In articles for heated smokers, an aerosol is generated by heating an aroma-generating substrate, such as tobacco. Known smokers' articles include, for example, electrically heated smokers' articles and smokers' articles, in which an aerosol is generated by transferring heat from a combustible heat source to a physically separate aerosol-forming material. During smoking, volatile compounds are released from the aerosol-forming substrate by transferring heat from the heat source and carried in the air aspirated through the smoking article. When the released compounds cool, they condense to form an aerosol that is inhaled by the consumer.
    [0004] Smokers' articles are known which comprise a capsule that releases a fluid, such as menthol.
    [0005] WO 2011/077141 A1 describes a filter for an article for smokers, which supposedly has a degree of biodegradation enhanced by means of a capsule in the filter, the capsule comprising a liquid capable of intensifying the disintegration of the smoking article. The liquid in the capsule can be colored in order to provide confirmation to the user that the capsule has been broken.
    [0006] EP-A-1895863 describes a cigarette, a capsule being provided between a first absorbent member and a second absorbent member of a filter element. The capsule is adapted to release at least part of a fluid, when the capsule is subjected to an external force, as well as tightening, by the consumer.
    [0007] However, the release of the fluid through this capsule is only detectable by changing the aroma or smoke composition of the article for smokers.
    [0008] Furthermore, this limited method for identifying fluid release makes it difficult for the consumer to know whether the fluid was released involuntarily, for example, in storage, since the release of a fluid, such as menthol, is not necessarily detectable after several days or weeks.
    [0009] It would be desirable, therefore, to obtain additional means to identify the release of the fluid. It would be especially desirable to obtain a solution that allows a consumer to use a different sense of smell or taste to determine the release of the fluid.
    [00010] It would be desirable, therefore, to obtain a means that allows the release of the fluid to be indicated to the consumer, in a way that remains visible.
    [00011] Therefore, according to the invention, an article for smokers is made available, which comprises a mouthpiece with a segment with a color change and a capsule containing fluid, which can be broken, and the segment of change of color. color is adapted to interact with the fluid in the capsule containing fluid that can be broken, and in this interaction the color change segment shows a visible color change from the outside of the article for smokers, when the capsule is broken.
    [00012] A color change offers a completely different way for a consumer to confirm the release of the fluid and has the added advantage that it is independent of the consumer's ability to identify the release through a change in flavor or aroma.
    [00013] The phrase "color change segment" indicates a part of the smoking article that changes color when in contact with the fluid in the capsule containing fluid, which can be broken. The color change may comprise the generation of a color that is different from the surrounding part of the article for smokers, the disappearance of a color that is equal to that of the surrounding part of the article for smokers, the change from opaque to transparent of a segment, the change from transparent to opaque of a segment, the appearance of a pattern, logo or other image, the change of a segment of any color or mixture of colors to another color or mixture of colors, regardless of whether they are the same or different from surrounding part of the article for smokers, or any other detectable change, which includes the appearance, disappearance or change of color or of a logo, image or print of the part of the article for smokers. The color-changing segment is preferably a mouthpiece segment, such as a filter segment, or a wrap, such as an inner or outer wrap.
    [00014] The "color change" phase indicates the result that is visible in the color change segment, when the fluid contacts the segment.
    [00015] The color change occurs, preferably, in an outer layer of the article for smokers. When there are multiple layers, the color change can occur on a layer that is not the outermost layer. This has the advantage that the fluid that interacts with the color-changing segment is preferably prevented from coming into direct contact with the consumer's lips or fingers.
    [00016] Therefore, it is especially desirable for the outermost layer to be an impermeable layer. This further reduces the possibility of the fluid coming into direct contact with the consumer's lips or fingers. Therefore, it is especially preferred that the impermeable layer is impermeable to water.
    [00017] The color change segment preferably comprises part of a layer, therefore, the layer undergoing a color change in a localized part when it comes in contact with a certain fluid.
    [00018] Preferably, the color-changing segment comprises at least part of one of the outer layers of the mouthpiece.
    [00019] The mouthpiece in which the color change segment is located, can be opaque or transparent. It is preferable that the mouthpiece is opaque. This allows the consumer to see the color change more easily, as an opaque background offers greater contrast than a transparent background.
    [00020] The term "opaque" is used to describe a material that prevents at least a significant proportion of incident light from passing through, so that it is not possible to see through the material. Preferably, "opaque" indicates a total percentage of light transmission of about 40% or less, particularly preferably, about 30% or less, especially preferably, about 25% or less, most preferably , 15% or less, as measured using a Hunterlab Colorquest XE spectrophotometer.
    [00021] The outer layer of the mouthpiece can be a wrap, which is at least partially wrapped around at least part of the mouthpiece.
    [00022] Articles for smokers according to the invention, which comprise a mouthpiece and a color changing segment, may wear out in the form of filter cigarettes or other articles for smokers, in which we want to fill tobacco fragments or other material suitable for being smoked is burned to form smoke. The invention further comprises articles for smokers, in which tobacco material or other aerosol-generating substrate is heated to form an aerosol, rather than flared, and articles for smokers, in which an aerosol, particularly an aerosol containing nicotine, it is generated from a tobacco material, tobacco extract or alternative nicotine source or other aerosol-forming substrate, without combustion or heating.
    [00023] In the description below, the term "mainstream smoke" is used to describe both mainstream smoke produced by articles for combustible smokers, such as filter cigarettes, and mainstream aerosols, produced by articles for non-combustible smokers , such as articles for heated or unheated smokers of the types described above.
    [00024] As used herein, the terms "upstream" and "downstream" are used to describe the relative position of parts or components of mouthpieces and articles for smokers according to the invention, in relation to the direction of the smoke from. main chain aspirated through the mouthpieces and smokers' articles during their use. For example, in a mouthpiece, where the color change segment is upstream of an end segment of the mouth, the mainstream smoke is sucked in first through the change and color segment and then through the end segment of the mouth.
    [00025] As used herein, the term "length" indicates the dimension in the longitudinal direction of the segments, mouthpieces and articles for smokers releasing aroma according to the invention.
    [00026] In a preferred aspect the mouthpiece comprises a filter and the color change can occur in the filter.
    [00027] Therefore, when the fluid is released from the capsule, the consumer sees a color change on the outside of the filter and, therefore, knows that the fluid has been released. The fluid release can be activated by applying pressure on the filter, such as by tightening the filter, so that the capsule breaks and releases the fluid.
    [00028] Preferably, the color change can be made in a predetermined part, so that a predetermined shape, such as a trademark, logo or other print is visible to the consumer.
    [00029] In one aspect, the fluid in the capsule is colored. Therefore, the fluid itself may initially contain the desired dye, which is visible to the consumer when the fluid is released from the capsule. In that case, it is preferred that the color change segment comprises a material that can absorb the colored fluid and thus change color
    [00030] In another aspect, the fluid can interact with a dye provided for in the color change segment. Therefore, the fluid, which may not itself comprise a dye, interacts with and thereby activates a dye provided for in the color change segment, so that a color change is visible to the consumer. This offers the benefit that only in some areas of the filter element the dye needs to be provided, while the fluid released from the capsule is not colored in the other regions of the filter element.
    [00031] In yet another aspect, neither the fluid nor the color-changing segment comprises a dye, but their interaction generates a color when the fluid and the color-changing segment come into contact with each other.
    [00032] The capsule can be a fluid reservoir, which can be ruptured, and comprises about 0.1 ml to about 1.0 mil of a fluid. Suitable capsules are preferably spherical or elliptical. Preferred diameters are from about 2.9 mm to about 6.2 mm.
    [00033] In a preferred aspect, the color-changing segment may be provided in a wrapper, which surrounds at least part of the mouthpiece. An article for smokers according to the invention may comprise more than one wrap. In this modality, the segment of color change may be provided inside an external wrap.
    [00034] In some embodiments, the capsule may comprise an additive, which modifies the smoke characteristics of the article for smokers. Such additives can comprise flavors, neutralizing agents or other smoke modifiers, such as chemical reagents. In addition, additives may also include diluents, solvents or processing aids in a preferred embodiment. Additives may include one or more flavors, such as liquid or solid flavors, and flavor formulations or materials containing appropriate flavors include, but are not limited to, menthol, mint, such as peppermint and green mint, cocoa, licorice, citrus and other fruit flavors, octalactone range, vanillin, ethyl vanillin, refreshing breath flavors, spice flavors such as cinnamon, methyl salicylate, lanalool, bergamot essence, geranium essence, lemon essence, ginger essence and tobacco aroma.
    [00035] Preferably, the capsule containing the fluid that carries out the color change is provided in a porous segment of the mouthpiece, so that the fluid contained within the capsule easily reaches the exterior of the porous segment, when the capsule is broken. In this case, it is believed that the fluid moves through a capillary effect in the porous segment. When the color change segment is located on a layer adjacent to and surrounding the porous segment, the color change occurs as soon as the fluid reaches the outer side of the porous segment.
    [00036] The porous segment can be a porous filter segment. A suitable porous filter segment may be formed of cellulose acetate, preferably with a low filtration efficiency, with a high absorption capacity. The porous filter segment can, in particular, be made of a single high denier material, with a weight of about 8.0g per 9km.
    [00037] The low filtration efficiency of the porous filter segment allows the fluid to flow towards the inner surface of the layer comprising the color-changing segment, to enable the color change and indicate that the capsule has released the fluid.
    [00038] In one embodiment, the mouthpiece can comprise only the porous filter segment.
    [00039] In a preferred embodiment, the article for smokers comprises a first and a second capsule located, in each case, in the first and second porous filter segments, the first segment being upstream of the second segment. The first capsule can contain the fluid to effect the color change and the second capsule can contain an additive, such as a flavoring. In a preferred aspect, the second filter segment has a lower absorption capacity than the first segment, so that the fluid released from the second capsule moves very slowly through the second filter segment, while the fluid from the first capsule quickly reaches the outer surface of the first filter segment. This has the advantage that the indicator that the flavoring is released can be perceived by the consumer before or at the same time that the flavoring reaches the consumer's mouth.
    [00040] This has the additional advantage that the fluid that effects the color change, in general, does not reach the consumer's mouth or change the color of the end of the mouth of the second seed filter.
    [00041] Preferably, the second filter segment has a minimum length of about 7 mm and is a fibrous filter material, such as cellulose acetate. Additional absorbent material, such as activated carbon, may be present in this segment.
    [00042] The second filter segment preferably has a high filtration efficiency, that is, a low absorption capacity. This has the advantage of preventing or reducing the absorption of the fluid released into the second filter segment.
    [00043] In one embodiment, the second porous filter segment is a mouth end filter segment. Preferably. it is about 10 mm long or longer.
    [00044] It is particularly preferred that the fluid causing the color change remains substantially in the first filter segment. Therefore, it is preferable that at least about 80%, particularly preferred, about 90% of the fluid remains in the first filter segment.
    [00045] In one embodiment, the mouthpiece comprises an internal waterproof wrap for liquids. Therefore, the fluid that effects the color change, when the capsule is ruptured, reaches, but does not cross, the internal envelope. This prevents contact with the consumer, especially the consumer’s fingers, and thus maintains a dry feel to the touch, which is typically desired by consumers.
    [00046] Preferably, an inner wrap is a wrap that surrounds at least one filter segment of the filter element. The inner wrap can connect several filter segments of a filter element, preferably up to five segments. The individual filter segments may, in particular, comprise absorbents, flavors, plant materials, botanical species or spices. Some or all of these segments may at least be partially visible through one or more transparent sections of the inner wrap. The transparent sections can be sections cut by stamping.
    [00047] In one embodiment, the filter element comprises at least one opaque, permeable inner wrap. In particular, the inner wrap may have a higher absorption capacity than the respective adjacent filter segments. Therefore, the inner wrap absorbs the fluid supplied by the capsule in a high concentration and therefore provides the color-changing segment. The opaque, permeable inner wrap may consist of a paper wrapper weighing about 20 grams per square meter (gsm) to about 30 gsm.
    [00048] The inner wrap may be provided with a dye The dye may be arranged on the inner side of the inner wrap. For a permeable inner wrap, the dye can be distributed along the itne3rno wrap.
    [00049] In one embodiment, the outer wrap is opaque and comprises a cutout. The cutout can be any type of opening, but a die cut opening is preferred. The outer wrap can be formed of standard tip paper, particularly, weighing from about 40 to about 60 gsm. An uncontrolled air flow through the opening in the outer casing is normally prevented by combining with a substantially impermeable inner casing.
    [00050] In one embodiment, the outer wrap is transparent and partially printed or engraved by means of printing or engraving, the outer wrap can be transparent only in predetermined areas, namely, in the areas where the color change occurs. Printing can provide marketing information or it can serve to design the article for smokers. In addition, the outer wrap may be embossed, the embossing being for the purpose of providing a mouth feel similar to the consumer as for an outer wrap of paper. In addition, printing can interact with the color change effect, so the color change effect changes the shape of a previously printed image in the color change effect area.
    [00051] Preferably, the outer wrap is impermeable.
    [00052] Alternatively, the outer wrap is permeable and is provided in a first region with an impermeable coating, such as a varnish, in order to make the premia substantially impermeable. Therefore, the permeable region of the outer envelope comprises the color-changing segment, and the fluid effects a color change in the outer envelope in the permeable region.
    [00053] The inside of the filter typically comprises at least one filter segment, with a capsule disposed in it, the capsule enclosing a fluid, which is released when pressure is applied to it.
    [00054] In a preferred embodiment, the at least one filter segment is surrounded by an inner wrap, which is formed of a transparent, impermeable film material, particularly a cellulose material, which is treated with an anti-stain varnish. Around the inner wrap, an outer wrap made of standard pointed paper is arranged, which comprises a stamped opening, so that a window is made available on the pointed paper. The window allows a consumer to see the effect of a color change inside the inner wrap, after breaking the capsule. In this modality, the color change is made when the fluid from the capsule reaches the transparent internal envelope. The consumer can observe the color change through the opening stamped on the outer wrap. For example, the color of the cellulose acetate in the filter segment changes due to the color of the fluid that was released.
    [00055] In another preferred embodiment, the at least one filter segment is surrounded by a transparent film, and the outer wrap is formed by a transparent tip film. The transparent tip film can be at least partially printed or engraved. Therefore, at least through the unprinted areas of the outer wrap, the color change can be seen inside the inner wrap. In this mode, the filter segment changes its color when it comes in contact with the fluid to effect the color change. The consumer can see the color change through the transparent inner and outer wraps. Preferably, only a transparent window is provided in the outer wrap while the remaining outer wrap is embossed and / or printed, so that it is not transparent The outer wrap or the inner wrap can both be impermeable to the capsule fluid.
    [00056] In another preferred embodiment, the at least one filter segment is wrapped with an opaque, permeable inner wrap, and a transparent, impermeable outer wrap. Therefore, when the inner casing interacts with the fluid from the ruptured capsule, a color change can be seen through the transparent outer casing. In this modality, the effect of color change can be seen when the fluid reaches the permeable internal envelope and interacts with it, as at least a transparent, unprinted part of the external envelope is expected in this region. Therefore, the coloring of the porous inner wrap confirms that the aroma has been distributed.
    [00057] In another preferred fashion, an opaque, permeable inner wrap surrounds at least one filter segment, and an opaque, at least partially permeable outer wrap is wrapped around the inner wrap. The partial permeability of the outer wrap can be achieved by treating only a part of the outer wrap with an anti-stain varnish. Therefore, the untreated part of the outer wrap is permeable and absorbs the fluid and therefore a color change is made on the outside of the outer wrap. In this modality, the color change is made when the fluid is dispersed through the permeable inner wrap and is then absorbed by the permeable part of the outer wrap. Therefore, the permeable part of the outer wrap changes its color, and the consumer sees that the aroma has been distributed.
    [00058] Nozzles for use in the invention can be single-segment nozzles or filters.
    [00059] Alternatively, mouthpieces for use in the invention may be multi-component mouthpieces, which comprise one or more segments, in addition to the color changing segment.
    [00060] Mouthpieces for use in the invention may comprise one or more segments upstream of the color change segment.
    [00061] Alternatively or in addition, mouthpieces for use in the invention may comprise one or more segments downstream of the color changing segment. This advantageously reduces the possibility that the fluid that interacts with the color-changing segment will come into direct contact with a consumer's mouth.
    [00062] Mouthpieces for use in smokers' articles according to the invention may comprise one or more segments comprising fibrous filtration materials, such as cellulose acetate tow.
    [00063] The mouth end segment may comprise a hollow tube or recess. The hollow tube or recess can be formed when the mouthpiece is connected to a stick of material suitable for smoking by, for example, pointed paper, to form a smoking article according to the present invention. Preferably, the recess further comprises a cylindrical element, which adds structural strength to the tube, for example, a paper or cardboard tube that is over-encased by the tip material. Indentation filters are well known in the art, for example, in European patent application WO-A-2004/089124.
    [00064] The mouthpiece may comprise a limiting segment. A limiting segment affects the aspiration resistance and other fluid dynamics of the smoking article and also affects the formation of carbon monoxide and carbon dioxide. Limiters on smokers' articles are known in the art, for example, from international patent application WO-A2-2008 / 059377.
    [00065] The mouthpiece may comprise a mouth end segment downstream of the color changing segment comprising a cellulose acetate tow plug or other fibrous filtration material.
    [00066] Mouthpieces for use in the invention may include one or more additional segments, which comprise absorbents (for example, activated carbon or silica gel), plant material (for example, tobacco blades), flavorings and other modifying agents. smoke.
    [00067] The one or more additional segments can be used to obtain a desired plasticizer content in the mouthpiece.
    [00068] Alternatively or additionally, one or more additional segments can be used to obtain a desired total suction resistance (RTD) of the mouthpiece.
    [00069] Nozzles for use in the invention can have an aspiration resistance (RTD) of, for example, between about 100 mm WG (water gauge) and about 180 mm WG, as measured from according to ISO 6565: 2002.
    [00070] Nozzles for use in the invention can have an outside diameter of, for example, between about 5 mm and about 8.5 mm.
    [00071] Nozzles for use in the invention can have a length of, for example, between about 20 mm and about 50 mm.
    [00072] When mouthpieces for use in the invention comprise a mouth end segment downstream of the color changing segment, the length of the mouth end segment could be, for example, between about 3 mm and about 15 mm , for example, between about 6 mm and about 12 mm.
    [00073] When the mouth end segment comprises a hollow tube or recess, the length of the mouth end segment can be, for example, between about 3 mm and about 8 mm.
    [00074] Mouthpieces for use in the invention can be incorporated into a wide variety of different types of articles for smokers. For example, mouthpieces for use in the invention can be incorporated into articles for combustible smokers, such as filter cigarettes, which comprise a stick wrapped with tobacco fragments, or other material suitable for smoking, which is burned during the act of smoking. smoke.
    [00075] Alternatively, mouthpieces for use in the invention can be incorporated into heated, non-combustible smoking articles, of the type described above, in which material is heated to form an aerosol, rather than being burned. For example, mouthpieces for use in the invention can be incorporated into articles for heated smokers, comprising a combustible heat source and an aerosol-forming substrate downstream of the combustible heat source, as described in WO-A-2009/022232 . Mouthpieces for use in the invention can also be incorporated into articles for heated smokers, which comprise non-combustible heat sources, for example, chemical heat sources or electrical heat sources.
    [00076] Alternatively, mouthpieces for use in the invention can be incorporated into smoking articles n
    [00077] For fuels, of the type described above, in which an aerosol is generated for an aerosol generating substrate without combustion or heating, such as those described in documents WO-A-2008/121610 and WO-A-2010/107613.
    [00078] In one embodiment, articles for smokers according to the invention may comprise a stick wrapped with tobacco fragments or other material suitable for smoking, attached to the mouthpiece by a pointed paper.
    [00079] In another fashion, articles for smokers according to the invention may comprise an aerosol generating substrate upstream of the mouthpiece.
    [00080] Articles for smokers according to the invention may comprise ventilated mouthpieces, in order to mix ambient air with main current drawn through the mouthpiece by a consumer during smoking. For example, one or more circumferential rows of perforations may be provided at a location along the mouthpiece by a consumer during smoking.
    [00081] Articles for smokers according to the invention can have a ventilation level of, for example, between about 20% and about 80%, as measured according to ISO 9512-2002.
    [00082] Articles for smokers according to the invention can have a total length of, for example, between about 60 mm and 128 mm.
    [00083] Articles for smokers according to the invention can have an external diameter of, for example, between about 5 mm and about 85 mm, for example, between about 5 mm and about 7.1 mm, for articles for smokers sized finely, or between about 7.1 and about 8.5 mm for articles of normal size smokers.
    [00084] The mouthpiece for use in the present invention can comprise a filter. The filter may comprise one or more fibrous filter segments.
    [00085] When a filter comprises multiple segments, it can be produced by forming separate, continuous rods that comprise multiple units of each individual filter segment. Then, these separate rods are combined in a known manner in one or more stages to form a continuous filter rod comprising multiple filter units. The continuous filter rod can then subsequently be cut at regular intervals by a cutting mechanism to produce a succession of separate filters according to the invention.
    [00086] Preferably, articles for smokers according to the present invention comprise a stick wrapped with filling of tobacco fragments. Preferably, articles for smokers according to the present invention have a dry, total nicotine free (NFDPM) or "tar" distribution of up to and about 10 mg. Particularly preferably, the "tar distribution" is between 1 mg and 10 mg and, especially preferably, about 6 mg.
    [00087] Preferably, the color change segment, when located in the mouthpiece, adjoins the stick wrapped in material suitable for smoking.
    [00088] The invention is now described further, with reference to exemplified modalities, as shown in the figures.
    [00089] Figure 1 shows a cross-sectional view of a filter element according to a first embodiment of the invention.
    [00090] Figure 2 shows a cross-sectional view of a filter element according to a first embodiment of the invention.
    [00091] Figure 3 shows a cross-sectional view of an article for smokers according to a first embodiment of the invention.
    [00092] Figure 4 shows a cross-sectional view of an article for smokers according to a second embodiment of the invention.
    [00093] Figure 5 shows a perspective view of an article for smokers according to an embodiment of the invention.
    [00094] In Figure 1 there is shown a mouthpiece in the form of a filter element 1 according to a first embodiment of the present invention. The filter element 1 generally consists of a first filter segment 2, a rod end filter segment 3 and a mouth end filter segment 4. The filter segments 4, 2, 3 are arranged adjacent each other in the longitudinal direction 100. The longitudinal direction 100 corresponding to the axial direction of the cylindrical filter element 1. The rod end filter segment 3 is arranged in such a way that it abuts a smoking material rod in a smoking article, while the mouth end filter segment 4 is arranged downstream at the mouth end of the article. for smokers.
    [00095] In the first filter segment 2, a capsule 5 is provided. The capsule involves a fluid, which is released when the capsule 5 is subjected to pressure and, therefore, breaks. Capsule 5 is embedded in the filter material of the first filter segment 2, namely cellulose acetate. The rod end filter segment 3 and the mouth end filter segment 4 can also be produced from cellulose acetate.
    [00096] Preferably the absorption capacity of the first filter segment 2 is higher than the absorption capacity of the mouth end filter segment 4 or the rod end filter segment 3. Therefore, the fluid released 5 it remains substantially in the first filter segment 2 and is rapidly distributed to its outer circumference.
    [00097] The fluid in capsule 5 comprises a flavoring and, therefore, when it is released, it modifies the aroma of the smoking article. But, in other embodiments, the fluid contained in the capsule 5 may comprise only an additive, which modifies the constitution of the smoke provided by a smoking element.
    [00098] The fluid in the capsule 5 comprises a dye, so that upon release of the fluid, the material of the first filter segment 2 is colored.
    [00099] The first filter segment 2, the rod end filter segment 3 and the mouth end filter segment 4 are surrounded by an inner wrap 6, so that they are connected to each other. The inner wrap 6 may be formed of a transparent, impermeable material, or an opaque, permeable material. But, in any case, the released fluid makes a color change, which is visible on the external side of the filter element 1. In these modalities, in which the fluid contained in the capsule, does not comprise a dye, it can be predicted both in the first segment of filter 2 as in the inner casing 5, so that when the fluid reaches the dye, a color change is made.
    [000100] It must be emphasized that the filter segment at the end of the rod 3 is optional, and that the first filter segment 2 may also be provided at the end of the filter element 1, so that it directly abuts the material rod to smoke. In other embodiments, only one filter segment with the capsule in it can be provided in the filter element.
    [000101] In Figure 2 there is shown a second embodiment of a mouthpiece in the form of a filter element 1 according to the invention. The filter element 1 comprises a first filter segment 2 with a capsule 5 disposed on an upstream side, which is the rod end side of the filter element 1. A second filter segment 7, with a second capsule 8, is provided adjacent to the first filter segment 2 at a downstream location.
    [000102] In some embodiments, the second filter segment 7 may be shorter than the first filter segment 2 in the longitudinal direction 100. The shortest length is possible, since the filter material of the second filter segment 7 it comprises a lower absorption capacity than the filter material of the first filter segment 2 and, therefore, the fluid of the second capsule 8 is dispersed a shorter distance than the fluid of the capsule 5 of the first filter segment 2.
    [000103] In addition, adjacent to the downstream direction of the second filter segment 7, a filter segment 4 of the mouth end 4 is provided. The filter segments 4, 7, 2 are arranged adjacent to each other in the longitudinal direction 100 The respective filter segments 2, 7, 4 are surrounded by the inner casing 6. The capsule 5 comprises a fluid with a dye, the second capsule comprising a fluid with an additive, such as a flavoring. When the consumer squeezes the filter element, the first and second capsules 5, 8 break. The first filter segment 2 has a higher absorption capacity than the second filter element 7, so that the fluid dispersion from the first capsule in the first filter segment 2 is carried out more quickly than the fluid dispersion in the second filter segment 7. Therefore, the fluid from the first capsule 5 quickly reaches the inner envelope 6 and provides the effect of changing the color therein. The inner wrap 6 can be a transparent, impermeable material, or an opaque, permeable material, as specified in the previous embodiment. Since the color change function and the flavor release function are provided by different capsules, a more localized supply of the color change effect can be obtained, while preventing the color from reaching the consumer's mouth. In addition, the mouth end filter segment prevents the flavoring from being dispersed in a liquid form to a consumer's mouth.
    [000104] In Figure 3, a first embodiment of an article for smokers 9 according to the present invention is shown. The article for smokers 9 comprises the filter element according to the second embodiment, as shown in Figure 2. In particular, the article for smokers 9 comprises a rod of smoking material 10, which is connected by means of an external wrap 11 on the filter element 1. The outer wrap surrounds the downstream part of the smoking material rod and the filter element 1. The outer wrap 11 is formed of an opaque material, particularly a standard pointed paper. The outer wrap 11 comprises an opening 12 in the area of the first filter segment 2. The inner wrap 6 is a transparent, impermeable wrap. Therefore, when the smoking article 9j is squeezed in the area of the filter element, the capsules 5, 7 rupture and their fluid is released, the fluid from the first capsule 5 being rapidly distributed through the first highly absorbent filter segment 2 and the colored material of the first filter segment 2 is visible through the transparent inner wrap 6 and the opening 12 in the outer wrap 11. However, the remaining mouth end of the filter element 1 offers the usual look and feel of a wrapping paper. standard tip.
    [000105] In Figure 4 a second embodiment of an article for smokers 9 according to the present invention is shown. The article for smokers 9 according to the second modality also comprises a filter element 1 according to the second modality, as shown in figure 2. But, unlike the first modality of the article for smokers 9, the inner wrap 6 and the outer casing 11 are both formed of a transparent material. The transparent material of the outer wrap 11 can be printed or engraved. However, in the region of the first capsule 5, a transparent window is provided in the eternal wrapper 11 that allows the visibility of the color change made by the fluid provided by the first capsule 5. The inner wrapper 11 in the second modality of the article for smokers 9 can be an opaque, permeable wrap, or a transparent impermeable wrap, since the outer wrap 11 provides the impermeability necessary to prevent fluid containing dye from reaching the outside.
    [000106] The configuration and arrangement of the internal and external envelope, as described with reference to Figures 3 and 4, can be applied to any type of filter segment configuration in the filter element. For example, a filter element 1 according to Figure 1, or a filter element with only one filter segment containing a capsule, which contains a fluid with a dye and an additive, such as a flavoring, can be provided.
    [000107] In Figure 5, an article for smokers according to one embodiment of the present invention is shown in a perspective view. As can be seen, a color-changing effect in the form of an image 13 is visible on the outside of the outer wrap11. Therefore, before the capsule breaks, no symbol is visible and, when broken, the symbol appears quickly. The symbol 13 can be a representation of the type of flavoring released, such as a mint leaf or the like.
