    [001] The present invention relates to a smoking article including a wrapper forming a mouth end cavity and including one or more symbols applied to the inner surface of the mouth end cavity. The present invention also relates to a method for producing such a smoking article.
    [002] Various types of smoking articles are known, including some smoking articles in which the smoke material is burned and other smokeless articles in which no combustion occurs. As an example of a combustion smoke article, filter cigarettes typically comprise a cylindrical filter aligned in an end-to-end relationship with a rolled tobacco rod, with the filter attached to the tobacco rod by the tip paper. In such filter cigarettes, the filter may consist of a filter made of a fibrous filtration material, such as cellulose acetate tow, wrapped in a porous filter wrap. Conventionally, the rolled tobacco rod and the filter are joined by the tip wrapper which is typically formed of a strip of paper material that circumscribes the entire length of the filter and an adjacent portion of the rolled tobacco rod.
    [003] As an example of a smokeless smoking article, several smoking articles, in which the tobacco is heated rather than burned, have been revealed. In heated tobacco articles, an aerosol is generated by heating an aroma-generating substrate, such as tobacco. Known heated smoking articles include, for example, electrically heated smoking articles and smoking articles in which an aerosol is generated by transferring the heat from a fuel element or heat source to a physically separate aerosol forming material. During smoking, volatile compounds are released from the aerosol-forming substrate by heat and dragged into the air pulled through the smoke article. As the released compounds cool, they condense to form an aerosol that is inhaled by the consumer. As another example of a non-combustible smoking article, smoking articles in which an aerosol containing nicotine is formed from a tobacco material or other source of nicotine without combustion and without the addition of heat have been disclosed, such as those described in WO -A- 2008/121610 and WO-A-2010/107613. In these types of smoking articles, a chemical source is provided to generate the aerosol containing nicotine.
    [004] It was previously proposed to provide wraps in tobacco articles that were printed with a graphic design, in order to present the tobacco article with a more aesthetically attractive appearance. Such an impression may be a continuous repetition pattern covering all or a portion of a tobacco rod wrap or sharp paper, or it may be discrete or graphic symbols.
    [005] It would be desirable to create a smoking article with new ways of displaying symbols, such as text, images, letters, words, logos, templates or similar. It would be particularly desirable to present a smoking article having such new ways of displaying graphics or symbols without significantly affecting the overall dimensions of the smoking article. In addition, it would also be desirable if such a smoking article could be assembled using standard packaging apparatus and techniques.
    [006] According to the invention, an article of smoke is presented comprising a tobacco rod and a mouthpiece. The nozzle comprises at least one segment and an envelope circumscribing the at least one segment and defining a cavity at the end of the mouth. The nozzle is in axial alignment with the tobacco rod and has an end of the rod adjacent to the tobacco rod and an end of the mouth opposite the end of the rod. One or more symbols are applied to the inner surface of the wrap portion defining the mouth end cavity.
    [007] The inclusion of the mouth end cavity increases the area for the printing of symbols without the requirement to significantly increase the overall dimensions of the smoking article. By providing the symbols on the inner surface of the mouth-end cavity, the consumer can have a strong visual impact and a distinctive product. In addition, the visible surface area in the smoking article can be increased with only a limited effect on the filtration efficiency of the smoking article.
    [008] The tobacco rod of the present invention is preferably formed of a tobacco material adapted to be burned to form smoke, such as with a cigarette or other combustible smoke article. Alternatively, the tobacco rod can be any aerosol-generating substance that contains tobacco or another substance containing nicotine. As such, the nozzles according to the present invention can be used to advantage in filter cigarettes and other smoking articles in which the tobacco material is burned to form the smoke. The nozzles according to the present invention can also be used in smoking articles in which the tobacco material is heated to form an aerosol, instead of being burnt. The nozzles according to the present invention can also be used in smoking articles in which an aerosol containing nicotine is generated from a tobacco material, tobacco extract or other source of nicotine, without combustion or heating.
    [009] The term “symbols” is used to refer to a discrete printed element or repeated printed elements or models that provide an aesthetically pleasing representation. Symbols can be in the form of text, images, letters, words, logos, templates or a combination of these. For example, the symbols on the inner surface of the mouth-end cavity according to the present invention may comprise a manufacturer's brand or logo that allows the consumer to identify the type or origin of the smoking article. Alternatively, the symbols may comprise a repeated printed element or pattern on the inner surface of the wrap material. The symbols can generally be aligned with the geometric axis of the smoking article, generally perpendicular to the geometric axis of the smoking article or at an angle other than parallel or perpendicular to the smoking article. In addition, different symbols could be produced on various smoking articles that are sold together. For example, in a package, smoking articles can include two or more different types of symbols. In addition, the symbols could be presented in a way that presents a message, for example, with the symbols on adjacent smoking articles in a package visible when the package is opened and the visible symbols spelling a word or otherwise collectively transmitting a message. message.
    [0010] To form the mouth end cavity, the mouthpiece has a segment, such as a filter segment or other structure, and the wrap extends beyond the mouth end of the segment to form the mouth end cavity. The nozzle segment can have an internal structure, such as a hollow cylinder, or it can be a cavity type filter as described in more detail below. The wrap may extend beyond the mouth end of the segment by between approximately 2 mm and approximately 10 mm, preferably between approximately 4 mm and approximately 7 mm. The area of the visible inner surface of the wrap can be between approximately 50 square millimeters and approximately 250 square millimeters, preferably between approximately 100 square millimeters and approximately 200 square millimeters, more preferably between approximately 100 square millimeters and approximately 175 square millimeters. The area of the inner visible surface of the wrap can be at least approximately 5%, preferably at least approximately 10% of the total visible surface of the nozzle.
    [0011] Where the wrap material is a sheet material as discussed below, the basic weight of the wrap material is preferably at least approximately 40 grams per square meter (gsm), more preferably at least approximately 60 gsm, more preferably at least approximately 80 gsm. In the alternative, or in addition, the base weight of the wrap material is preferably less than approximately 160 gsm, more preferably less than approximately 150 gsm and more preferably still less than approximately 140 gsm. The base weight of the wrap material is preferably between approximately 40 gsm and approximately 160 gsm, more preferably between approximately 45 gsm and approximately 150 gsm, more preferably between approximately 80 gsm and approximately 140 gsm. In general, it is advantageous to use a harder wrap material than for conventional smoking articles to reduce the possibility of the mouth end cavity closing during smoking of the smoking article.
    [0012] In addition to producing symbols on the inner surface of the wrapper defining the cavity at the end of the mouth, such symbols can be produced on the outer surface of the mouthpiece. When symbols are produced on the outer surface of the nozzle, they can be located only in the portion of the nozzle that defines the cavity, or they can extend along the nozzle to the end of the nozzle rod. In some embodiments, the external symbols can be produced on an outer surface of the wrap, while in other embodiments, the external symbols can be produced on the outer surface of an additional wrap material, such as a tip wrap, which is further described. bellow.
    [0013] The shape of the cross section of the smoking article can have a variety of shapes including round, oval, elliptical or egg-shaped.
    [0014] Where the nozzle of the tobacco articles according to the invention comprises a filter, the filter can be formed of a single segment or it can be a multi-segment filter comprising two or more filter segments which are connected in a longitudinal direction . Where two or more filter segments are provided, the filter segments may be of the same construction and materials as each other, but more preferably they have a different construction or contain different filter material or additives. In certain preferred embodiments of the present invention, the nozzle comprises a multi-segment filter including a filter segment comprising filtration material and a particulate material dispersed through the filtration material.
    [0015] Where the filter comprises two or more segments, the segments are typically wrapped in a filter wrap. Any or all of the two or more segments can each be individually wrapped in a filter wrap. The two or more segments can be joined by a coupling filter wrap that couples the two or more segments together in an end-to-end relationship. That coupling filter wrap can be a wrap forming the mouth end cavity as described above or there can be a subsequent wrap which is arranged around the coupling filter wrap that forms the mouth end cavity.
    [0016] Preferably, the filtration material within the filter segment is a filter of fibrous filtration material, such as cellulose acetate tow or paper. A filter plasticizer can be applied to the fibrous filtration material in a conventional manner, by spraying it on the separated fibers, preferably before applying any particulate material to the filtration material.
    [0017] Alternatively or in addition to the filter segments described here, the multi-segment filter may include a hollow cavity at least partially filled with particulate material. In such embodiments, the hollow cavity is preferably produced between two filters of a filtration material.
    [0018] Preferably, between approximately 40% and approximately 100% of the cavity volume is filled with particulate material, more preferably between approximately 60% and approximately 80% of the cavity volume. Such cavity filters can be produced using machinery and techniques known to produce carbon filters. In such a technique, two filters of the filtration material are placed in a wrapping material with a space between them. The space between them is at least partially filled with the particulate material and then the wrap is wrapped around the filters, forming a cavity between the filters that is at least partially filled with the particulate material. A detailed process is described, for example, in EP-A-1,571,933. The machinery to perform these manufacturing methods is available from several sources. For example, Filtrona International Ltd. of Great Britain manufactures such machinery.
    [0019] The particulate material incorporated in the filter segments described above may include at least one sorbent capable of removing at least one constituent of the gas phase of the smoke from the stream drawn through the filter. Preferably, the at least one sorbent is selected from the group consisting of activated carbon, carbon beads, active aluminum, zeolites, sepiolites, molecular sieves and silica gel.
    [0020] Alternatively or in addition to at least one sorbent, the particulate material may include at least one flavoring material. For example, the particulate flavoring material may include particles of a sorbent or cellulosic material impregnated with a liquid flavoring. Alternatively, the particulate flavoring material may comprise particles of plant material. The plant material can be in the form of the plant leaf, as described in EP-A-1,958,523. For example, the filter segment can include tobacco leaf, green tea, peppermint, mint, bay leaf, eucalyptus, basil, sage, verbena and tarragon. In addition, portions of mint plants can also be used. The term 'mint' refers to plants that belong to the genus Mentha. The plant material may alternatively be in the form of a seed, root, bark, flower or combinations thereof, such as those typically used as seasonings.
    [0021] The tobacco articles according to the present invention can include a variety of different types of filter segments or combinations of filter segments, including those described above, as well as other types of filter segments that would be known to the skilled person. , such as segments including restrictors and segments that are used to adjust inhalation resistance (RTD).
    [0022] In a first aspect of the present invention, the wrap which includes one or more symbols is a filter wrap. In this first aspect, the smoking article may also comprise a tip paper, or tip wrap, circumscribing the nozzle and connecting the nozzle and the tobacco rod. The tip paper can advantageously increase the stiffness of the mouth end cavity wall in order to reduce the possibility that the cavity will close with smoke. Preferably, the tip wrap overlaps all or part of the filter wrap portion defining the mouth end cavity. The tip paper can be formed of a cellulosic paper sheet material, as in conventional cigarettes, and in this way, the consumer feels a familiar texture and mouth feel.
    [0023] In the first aspect, the filter wrap including one or more symbols may extend part of the way along the length of the nozzle from the end of the mouth, such that a portion of the nozzle at the end of the stem is not covered by the wrap of the filter. Preferably, a ventilation zone is provided positioned in the portion of the nozzle that is not covered by the filter housing. This can improve ventilation through the smoking article. More preferably, the ventilation zone comprises at least one circumferential row of perforations and the perforations extend through the tip paper. This provides ventilation for the smoke article, so that the smoke from the stream is mixed with the ambient air during the smoke. Where the nozzle comprises a filter, the circumferential rows of perforations are preferably produced at a location along the filter. Advantageously, where the filter wrap is substantially non-porous, not covering a portion of the nozzle with the filter wrap allows adequate ventilation through the ventilation zone.
    [0024] In the first aspect, alternatively, the filter wrap including one or more symbols may extend along the entire length of the nozzle, such that the entire nozzle, including the mouth end cavity is covered by the filter wrap. In a still further alternative, where the nozzle comprises at least one filter segment, the filter wrap is adapted to extend over the entire length of the filter segment or segments.
    [0025] Where the nozzle comprises a filter, preferably, perforations are produced between approximately 9 mm and approximately 20 mm from the end of the filter mouth. More preferably, the perforations are produced approximately approximately 12 mm from the end of the filter mouth. This can prevent the perforations from being blocked or closed by the consumer's lips during smoking.
    [0026] In a further aspect of the present invention, one or more symbols can be applied to the inner surface of a pointed paper that circumscribes the nozzle. In addition to the tip paper, a substantially transparent wrap in the form of a filter wrap can be provided that circumscribes the filter segment, or segments, as mentioned above. In this way, one or more symbols on the tip paper are visible through the substantially transparent filter wrap.
    [0027] The term 'substantially transparent' is used to describe a material that allows at least a significant proportion of the incident light to pass through it, so that it is possible to see through the material. In the present invention, the substantially transparent wrap allows sufficient light to pass through that the symbols on the tip paper are visible through the wrap. The substantially transparent wrap can be completely transparent. Alternatively, the substantially transparent wrap may have a lower level of transparency while still transmitting sufficient light that the symbols are visible through the wrap.
    [0028] The thickness of the substantially transparent wrap is preferably at least approximately 25 micrometers, more preferably at least approximately 35 micrometers and most preferably still approximately 40 micrometers. In addition, or alternatively, the thickness is preferably less than approximately 110 micrometers, more preferably less than approximately 80 micrometers. The thickness is preferably between approximately 25 micrometers and approximately 110 micrometers, more preferably between approximately 35 micrometers and approximately 110 micrometers, most preferably between approximately 40 micrometers and approximately 80 micrometers. The base weight of the substantially transparent wrap is preferably at least approximately 40 grams per square meter (gsm) and more preferably between approximately 40 gsm and approximately 80 gsm, more preferably still between approximately 40 gsm and approximately 60 gsm. Materials suitable for use as the substantially transparent wrap of the tobacco articles according to the present invention include, but are not limited to cellophane, cellulose diacetate and polypropylene. Different qualities, thicknesses and basic weights of suitable substantially transparent materials are commercially available from various sources. For example, Innovia Films Ltd. and Clarifoil manufacture a variety of different types and qualities of such materials.
    [0029] The smoking articles according to the present invention can be a combustion smoking article, such as a filter cigarette or other smoking articles, in which the tobacco material or other combustible material is burned to form the smoke . Alternatively, the tobacco articles according to the present invention can be non-combustible. As an example, non-combustible smoking articles may include material that is heated to form an aerosol, rather than burned. In a type of heated tobacco article, the tobacco material or other aerosol forming material is heated by one or more electric heating elements to produce an aerosol. In another type of heated smoke article, an aerosol is produced by transferring the heat from a combustible or chemical heat source to a physically separate aerosol-forming material, which can be located inside, around, or downstream of the heat source .
    [0030] Alternatively, filters according to the invention can be incorporated into tobacco articles, in which an aerosol containing nicotine is formed from a tobacco material or other source of nicotine without combustion and without heating, such as those described in WO- A-2008/121610 and WO-A-2010/107613.
    [0031] Where the smoking article is non-combustible, the wrap may be a tube that forms the cavity at the mouth end of the smoking article. For example, the wrap can be a plastic tube. In addition, any internal structures within the tube may be integral with the tube or may be placed and otherwise secured within the tube.
    [0032] The present invention further provides a method for making a nozzle for a smoking article as described here. The method comprises the steps of: providing a wrapping sheet material having one or more symbols applied to it; providing a plurality of filter elements; arranging the filter elements in the wrapper sheet material, so that the filter elements are separated with one or more symbols between two adjacent filter elements; wrapping the wrapper sheet material around a portion of the filter elements, such that the wrapper sheet material forms a mouth end cavity with the symbols arranged in the mouth end cavity. The nozzle produced by this process can then be cut along the mouth end cavity in order to create individual filters and expose the mouth end cavity.
    [0033] In some embodiments, this method produces a nozzle that includes all elements of more than one nozzle or filter. This is often referred to as a multiple nozzle or multiple filter. Where the multiple filter comprises all the elements of two filters, it can be called as a double filter. Other multiple filters have also been produced, for example, quadruple filters.
    [0034] The nozzle or filter can subsequently be combined with rolled tobacco rods or other types of aerosol generating substrate from the smoke article. For example, a tip wrap can be provided and wrapped around all or a portion of the nozzle and a portion of an adjacent tobacco rod, in order to connect the nozzle and the tobacco rod to provide assembled smoking articles. Where the process uses multiple filters, the multiple filters can subsequently be cut through the mouth end cavity of the multiple filters to create two or more finished tobacco articles and expose the mouth end cavity. The combination of the nozzle or filter and the rolled tobacco rods or other types of aerosol-generating substrate can occur online or offline on a machine that is separate from the machine used to produce the nozzles.
    [0035] The symbols can be printed continuously on the wrapper and, in this mode, no positioning of the filtration elements in relation to the printed symbols is required. In an alternative embodiment, the symbols are printed discreetly and are separated, such that one or more symbols are located in said mouth end cavity. In this modality, the wrap and the filtration elements need to be aligned, so that the symbols are visible in the cavity at the end of the mouth. Preferably, the position of the one or more symbols is recorded using an optical device to enable the positioning of each symbol.
    [0036] The symbols can be printed on the wrapper online or offline. As used here, the term online refers to the execution of printing the symbols as a step during the manufacture of the nozzle or smoking article. The term offline refers to the execution of the printing of the symbols as a separate process. In the case of offline printing, the process can be conducted using separate machinery in the same manufacturing facility as the nozzle or smoke article manufacture. Alternatively, offline printing can be conducted using separate machinery in a location alternating with the manufacture of the nozzle or smoke article.
    [0037] The invention will now be further described with reference to the following drawings in which: Figure 1 shows a perspective view of a smoke article according to the invention with a cavity in the end of the mouth, Figure 2 shows a schematic section of a smoke article according to the invention and Figure 3 shows a wrapper according to the invention with discrete symbols applied to the inner surface.
    [0038] Figure 1 shows a perspective view of a smoke article 100 comprising a filter segment 102, a tobacco rod 104 and a mouth end cavity 106. As can be seen, the mouth end cavity 106 it has symbols, in the form of text in this particular example, inside. The text is oriented, such that when the smoker is holding the smoking article in the conventional manner, the text is readable by the smoker. Likewise, where the symbols are graphic or similar, they are oriented in a similar way. The smoking article has a diameter of approximately 7.85 mm and a length of approximately 84 mm. The nozzle 101, which contains the mouth end cavity 106 and the filter segment 102, is approximately 32 mm long. The mouth end cavity is approximately 5 mm deep and approximately 7.45 mm in diameter. Therefore, the area of the inner surface of the wrapper defining the cavity is approximately 117 mm2 and the area of the total nozzle surface available to display the symbols and the like is 874 mm2 or the area of the inner surface of the wrapper defining the cavity is approximately 13 % of the total visible surface area of the nozzle.
    [0039] Figure 2 shows an embodiment of the smoking article according to the invention. The tobacco article comprises a tobacco rod 104 or any other type of aerosol generating substrate containing tobacco material or nicotine-containing material, a nozzle 101 and tip paper 202 used to join tobacco rod 104 with nozzle 101 The nozzle 101 comprises a mouth end cavity 106, which is defined by the wrap 212, and the tip paper 202. The nozzle also comprises two filter segments 204 and 206. Each filter segment is wrapped in respective filter wraps. 208 and 210. Ventilation in the form of perforations 214 is produced at the nozzle 101 upstream of the mouth end cavity. In this embodiment, the perforations 214 are produced adjacent to the filter segment 204 and extend through the filter wrap 208, the wrap 212 and the tip paper 202. Alternatively, where the filter wrap 208 is porous, the perforations can only be extend through wrap 212 and tip paper 202. Additionally, where wrap 212 is porous, perforations can only extend through tip paper 202.
    [0040] The mouth end cavity produces an internal surface area for the symbols to be displayed. Symbols or the like are printed on the inner surface of wrap 212.
    [0041] Wrap 212 has a basic weight of approximately 70 gsm to produce sufficient stiffness, so that the mouth end cavity 106 does not close when smoking the article of smoke.
    [0042] Figure 3 shows the inner surface of envelope 204 with discrete symbols 300 printed on a recurring model. During the continuous manufacture of the nozzles, a sheet material of wrap 212 with pre-printed symbols receives the filter segments, wrapped around the filter wrap, to form a nozzle complete with a mouth end cavity. The filter segments are arranged in the wrapper sheet material, so that each set of filter segments is separated with the symbols arranged in the open space. Optical recording equipment can be used to ensure that the filter segments are aligned with the symbols. The manufacturing equipment is adapted to cut the nozzles in sets of two. Each set of two nozzles being joined at the end of the mouth. The length of the double nozzle is suitable for use in standard cigarette making equipment.
    [0043] A tobacco rod is arranged in axial alignment with a nozzle at the end of the nozzle opposite the cavity at the end of the mouth and attached to the nozzle with a pointed paper. The tip paper and wrap sheet material are cut along the AA line, such that a portion of the wrap, including one or more symbols, extends beyond the filter segments of each nozzle to define the mouth end cavity .
    [0044] It will be found that, although the specific modalities described above refer to tobacco articles comprising a tobacco rod and filter, a similar arrangement of the mouth end cavity could also be used in a non-combustible tobacco article, such as described above.
