Description

Tobacco product comprising fluorescent or phosphorescent substance

The present invention relates to a tobacco product in the form of a filter cigarette comprising fluorescent or phosphorescent material.

Within the meaning of this document, a tobacco product comprising a fluorescent or phosphorescent substance is a tobacco product having at least one externally visible and/or detectable characteristic upon excitation of the fluorescent or phosphorescent substance. The printing according to the invention can also be applied to the packaging material of tobacco products, wherein this application is disclosed in the present application but is not claimed.

US2921587a discloses a filter cigarette comprising a luminescent and/or phosphorescent material which is applied to the outside of the wrapping material of the filter cigarette. There is no disclosure of what phosphorescent material is applied and/or whether or not or thereby ensuring safe use of the filter cigarette.

For safe use of fluorescent prints in conjunction with filter cigarettes, it is proposed in US 2015/0090274 A1 to place the fluorescent print on an additional envelope or end cap that must be removed prior to smoking the filter cigarette. Disadvantageously, ready-to-use cigarettes do not have any lighting characteristics and/or require additional wrapping on each individual filter cigarette.

For safe use of filter cigarettes comprising a luminescent coating, it is proposed in CN203058273U to cover the luminescent coating with a protective layer made of a water-based lacquer. Disadvantageously, the layer sealed with respect to the substance of the luminescent coating is producible with great effort only by using a coating of lacquer, which requires a time-consuming application using a relatively thick lacquer layer. Furthermore, such coatings using a lacquer may interact with the luminescent substance (due to the solvent of the protective lacquer), which may lead to a decay of the luminescent effect, or may cause luminescent substance to travel into deeper layers of the filter cigarette together with the solvent of the protective lacquer, or may cause the fine structure of the fluorescent coating to "wash off", i.e. become hazy. Given that the luminescent coating is carried out using nitrocellulose lacquer, the application of the water-based protective lacquer thus makes it possible to move the luminescent substance into the base paper or into the protective lacquer layer.

In US 2016108293 A1 it is proposed to apply a fluorescent substance using an adhesive or glue with which the individual components of the filter cigarette are adhesively bonded to one another. In a second embodiment variant, it is provided that the components of the tobacco product are provided with a print, which contains fluorescent substances. The embodiment variant with adhesive, which is provided under the paper of the glue layer and is therefore more difficult to perceive from the outside, has the disadvantage that the adhesive may not be applied in the area of the opening of the glue layer, since it would otherwise leave through this opening during the adhesive bonding and/or would make the area under the opening sticky, whereby it would disadvantageously adhere to machine parts, packages, or other cigarettes. In a second embodiment variant, neither a special layer structure of the filter cigarette nor another measure for protecting the printed fluorescent substance is proposed.

In US 2015041345 A1 it is proposed that the cigarette packets are provided with fluorescent markers. In one embodiment variant, it is provided that, for identifying the cigarette packs, fluorescent substances are contained in the paper of the cigarettes or are applied thereto, so that the cigarette packs are identifiable (due to the contained cigarettes). Neither a special layer structure of the filter cigarette nor another measure for protecting the fluorescent substance is proposed.

In CN 105013719A it is proposed that products are provided with codes to be able to identify and classify them, wherein these codes can be applied using fluorescent substances. Neither a special layer structure of the filter cigarette nor another measure for protecting the fluorescent substance is proposed.

The invention is based on the first object of making the use of fluorescent or phosphorescent substances on ready-to-use tobacco products safer, wherein the fine structure is also sufficiently displayable and sufficiently externally visible.

To achieve this, it is proposed to integrate the fluorescent or phosphorescent substances into the layer structure of the tobacco product, so that they are protected from contact and other external influences.

Specifically, a filter cigarette is proposed, comprising a filter, a filter wrapper enveloping the filter, a tobacco roll wrapper enveloping the tobacco roll, and a mouthpiece wrapper enveloping at least one sub-region of the filter wrapper and having an upper surface forming at least a part of a surface of the filter cigarette, wherein

The filter cigarette has at least one fluorescent or phosphorescent substance in a region of the mouthpiece envelope material below the upper surface of the mouthpiece envelope material, and wherein the mouthpiece envelope material has an opening or is embodied as a translucent or transparent film in at least one region of the fluorescent or phosphorescent substance, so that the at least one region is visible from the outside of the filter cigarette.

Another object on which the invention is based is to provide a tobacco product having features that are invisible in daylight and become visible only in the dark, or that can be made visible only by excitation of light having a specific wavelength.

To achieve this, it is proposed to apply fluorescent or phosphorescent substances which are colourless or whose colour is provided according to the lower surface to which they are applied. Those substances which emit light for a longer period after excitation are preferably applied such that they emit light in the dark after removal of the light and are therefore visible and readily detectable, wherein this effect of longer light emission is generally achievable by phosphorescence. The luminosity is preferably selected such that the print with the phosphorescent substance is not visible in daylight and becomes visible only in the dark or in soft light. It may also be preferable to apply those substances which emit light only temporarily or immediately after excitation, so that they can be made visible in the dark by illumination with UV light (invisible light) and do not emit light or emit light only weakly and thus are not visible in the dark after removal of the illumination with invisible light, wherein this effect of the brief emission is achievable overall by fluorescence. The luminosity is preferably chosen such that the print comprising fluorescent substances is not visible in daylight and can be made visible only in the dark or under soft light using invisible light.

Both objects according to the invention are achieved by using riboflavin which is applied as yellow imitation cork (yellow base paper or print) for the mouthpiece of filter cigarettes, or applied on, in or under it. Riboflavin is a yellow substance used in food technology as yellow food pigment (E101). Preferably, the lacquer containing riboflavin is applied on a layer below the open or translucent or transparent film of the mouthpiece wrapper, with the advantage that no further layer which might affect such lacquer or wash it off needs to be applied on the riboflavin print, which is located downwardly (in the direction of the interior of the filter cigarette) spaced from the outer side surface of the filter cigarette formed by the mouthpiece wrapper. The riboflavin print is thus protected from external mechanical influences.

The two objects according to the invention are also achieved by the use of quinine. Quinine is a colourless substance used in food technology as a bitter substance. Preferably, the lacquer containing quinine or a quinine derivative is applied on a layer below the open or translucent or transparent film of the mouth-piece wrapper, with the advantage that no further coating layers which may affect such lacquer or wash it off need to be applied on the quinine print, which is positioned downwardly (in the direction of the interior of the filter cigarette) spaced from the outer side surface of the filter cigarette which is formed by the mouth-piece wrapper. The quinine print is thus protected from external mechanical influences.

Both objects according to the invention can also be achieved by using other fluorescent or phosphorescent substances which are colourless or whose colour corresponds to their lower surface in normal ambient light, if they are integrated into the layer structure of the tobacco product, so that they are reliably protected from contact with these substances. In this case, preference is given to using strontium aluminates (and also strontium aluminum oxides), particularly preferably europium-doped strontium aluminates. Strontium aluminates, or strontium aluminates doped with europium, including colourless substances, have a particularly bright or particularly long-lasting luminosity, depending on the structure.

The fact that the tobacco product of the invention is in any case safer for use or during consumption and that the appearance of the tobacco product in daylight may not show changes with respect to conventional tobacco products is advantageous with respect to the prior art.

The applications according to the invention include the use of these fluorescent or phosphorescent substances to enable rapid finding of the tobacco product in the dark, or to improve the counterfeit protection, identification ability, or information content of the tobacco product.

In a preferred embodiment variant according to the invention, the fluorescent or phosphorescent substances are dissolved in a suitable solvent and subsequently blended with the lacquer or are dispersed in the lacquer and subsequently applied or printed on the tobacco product or one of its layers. The solvent and the lacquer are preferably colourless and preferably transparent. The paints can also be coloured using pigments and/or printing inks, whereby, however, the effect or luminosity decay of these fluorescent or phosphorescent substances. The application or printing of the lacquer provided with fluorescent or phosphorescent substances is carried out, for example, in the gravure printing process or another known printing process. The paint is preferably a nitrocellulose paint which is tested in use on a mouthpiece wrapper.

In a further preferred embodiment variant according to the invention, a layer with the fluorescent or phosphorescent substances, in particular a film doped with a fluorescent or phosphorescent substance, is arranged on or in the tobacco product. In this case, these fluorescent or phosphorescent substances are preferably encapsulated or incorporated into the polymer skeleton of the plastic film.

In a further preferred embodiment variant according to the invention, three-dimensional objects with the fluorescent or phosphorescent substances are placed in the interior of the tobacco product.

The claimed tobacco product is a filter cigarette according to the invention, which is implemented according to an exemplary embodiment variant of the invention.

The drawings of these figures are not to scale, in particular the layer thicknesses in the sectional images used to illustrate the layer structure. In particular, the layer thickness of the luminescent print 2 is shown disproportionately thick so that it is recognizable. Since a print with a layer thickness in the micrometer range is usually provided, this will not be visible to scale in this layer structure. The term luminescence is used in the sense of photoluminescence as a collective name for the terms phosphorescence and fluorescence. In the terms luminescent decal, luminescent film, and luminescent object, "luminescence" refers to luminescence in the form of luminescent light that is released by excitation with light of a matching wavelength via the effect of phosphorescence and/or fluorescence.

Figure 12 includes perspective views of cigarette packages including liners with and without UV illumination.

Fig. 1 to 8 and 12 show an embodiment variant according to the invention of a filter cigarette 1 comprising a luminescent print 2. As is known from the prior art, a filter cigarette 1 has a filter 3, a filter wrapper 4 enclosing the filter, a mouthpiece wrapper 5 enclosing the filter wrapper 4, and a tobacco roll wrapper 6 enclosing a tobacco roll. These wrappers are often also referred to as papers or as filter wrappers (or tipping papers) and mouthpiece cover papers (or tipping papers), even if they are not always embodied as papers, but can also be provided as films (e.g. plastic or cellulose films).

Fig. 1 shows a first embodiment variant according to the invention, in which the wrapper 5 is arranged as a tipping paper or cellulose film or tear strip comprising a full-surface luminescent print 2, wherein the luminescent print 2 is arranged on the outside of the filter-tipped cigarette 1, i.e. is accessible by a person's lips and/or fingers. A tear strip is understood to be a region of a single layer of mouthpiece enveloping material 5 which can be pulled off or a layer of a multilayer mouthpiece enveloping material 5 which can be pulled off, or the mouthpiece enveloping material 5 as a whole which can be pulled off. In contrast to wrappers known in the form of additional envelopes or end caps, the tear strip can also remain on the filter cigarette 1 during smoking so that the user can selectively decide whether he removes the tear strip. In this first embodiment variant, substances such as quinine or riboflavin, or combinations thereof, are applied via saliva, which substances are not critical at the time of contact and/or consumption. Alternatively, the mouthpiece enveloping material 5 can also be provided as a film doped with luminescent material, or can have a tear strip provided as a film doped with luminescent material.

Fig. 2 shows a second embodiment variant according to the invention, in which the luminescent print 2 is delimited as one or more sub-regions of the mouthpiece envelope material 5, which are located in the front region of the mouthpiece envelope material 5 so as not to be touched by the lips of a person during the intended use of the filter-tipped cigarette 1. The luminescent print 2 may be applied, in particular, in the form of one or more bands extending around the circumference of the filter-tipped cigarette 1, or as a pattern consisting of distributed, consecutive or separate printed sub-areas.

Fig. 3 shows a third embodiment variant according to the invention, in which a luminescent print 2 is applied on the underside, i.e. the side of the tipping wrapper 5 facing the filter wrapper 4, wherein the tipping wrapper 5 is at least sufficiently light-transmissive or translucent that the luminescent light released in the print is externally visible or detectable. In this variant, the mouthpiece enveloping material 5 is preferably provided as a transparent film made of plastic or particularly preferably made of cellulose hydrate. The luminescent print 2 may be provided on the entire surface of the underside of the mouthpiece envelope material 5, or on at least one sub-area, for example in the form of one or more bands extending around the circumference of the filter cigarette 1, or as a pattern consisting of distributed, consecutive or separate printed sub-areas. Less preferably, the luminescent print 2 may also be applied on the outside of the filter wrapper 4. Instead of the luminescent decal 2, it is also possible to use a luminescent intermediate layer in the form of a film doped with a luminescent pigment. This embodiment variant has the advantage that the luminescent print or luminescent film is arranged below the translucent to transparent mouthpiece enveloping material 5 and is thus protected from external contact from fingers or lips.

Fig. 4 shows a fourth embodiment variant according to the invention, in which the mouthpiece enveloping material 5 has at least one opening 8 which is preferably produced by laser cutting (laser die cutting) and exposes the layers of the underlying layer structure. An intermediate layer 7 made of a translucent material is applied below the opening 8, which intermediate layer may cover only the area of the opening 8, or of the ring shape of the mouthpiece enveloping material 5, closing off the opening 8, or the entire surface of the mouthpiece enveloping material 5. The print 2 is preferably applied to the underside of the intermediate layer 7, wherein the print can be limited to a sub-area of the surface of the opening 8. The intermediate layer 7 is preferably a transparent film made of plastic or in particular cellulose hydrate.

Fig. 5 shows a fifth embodiment variant according to the invention, in which the mouthpiece enveloping material 5 has a plurality of portions, wherein at least one translucent intermediate portion 9 is provided, which may preferably consist of a transparent film (made of plastic or in particular cellulose hydrate). The remainder of the mouthpiece envelope material 5 may consist of paper. The intermediate portion 9 is preferably provided as a ring-shaped portion and thus extends over the entire circumference of the filter-tipped cigarette 1. The intermediate part 9 preferably has a luminescent print 2 on its underside and/or consists of a film doped with a luminescent material.

Fig. 6 shows a sixth embodiment variant according to the invention, in which the mouthpiece enveloping material 5 of the first embodiment variant additionally has perforations 10. Small perforations 10 extending through the mouthpiece cover paper 4 are known from the prior art for improving the air permeability and are provided as a band of one or more small holes extending over the circumference of the filter cigarette 1. According to the invention, perforations 10 are provided which are larger than typical perforations so that they are well recognizable with the naked eye. In this case, the perforations 10 have a size of at least 0.3mm diameter. Upon excitation of the luminescent pigment, the perforations 10 become sufficiently visible. Ablation 18 is additionally shown in fig. 6, which ablation is produced according to the invention by ablating at least the material of the luminescent print 2 from the entire surface luminescent print 2 using a laser, wherein the tipping wrapper 5 may additionally also be at least partially ablated. Via ablation using a laser, a light-dark design may be provided that is not visible in daylight. Vice versa, it is also possible to provide the mouthpiece envelope material 5 with a light-emitting region or with a view showing the light-emitting region by means of transparent and opaque decals, and to provide the decal with ablations 18, which again show a view of the light-emitting region.

Fig. 7 shows a seventh embodiment variant according to the invention, in which the mouthpiece cover 5 has perforations 10, wherein a luminescent print 2 or a luminescent layer (film provided with and/or doped with luminescent particles) is applied below the mouthpiece cover 5 in the layer structure of the filter cigarette 1. When the luminescent material is excited by incident light having a matching wavelength, luminescent light is released outwards through the small openings of the perforations 10. If the holes of the perforations 10 are so small that they are imperceptible or hardly perceptible to the naked eye, they can be made clearly visible by excitation.

Fig. 8 shows an eighth embodiment variant according to the invention, in which the luminescent print 2 is applied as a QR code 11 or as part of a QR code 11. If the luminescent print 2 forms the QR code 11 itself, which is not visible to the observer, it can be entered and/or made visible via a suitable camera or only after excitation. The luminescent print 2 may also serve merely to highlight the outline of the QR code 11 upon excitation. Preferably, additional information items can be added to the visible QR code 11 by means of the luminescent stamp 2 (for example, by overprinting the visible QR code 11 with the luminescent QR code 11), which each contain different information items. Quinine is preferred for use in this embodiment variant because it has a small particle size and therefore good printing resolution can be achieved. The high image edge definition required for inputting the QR code can be achieved using quinine.

Fig. 9 shows a ninth embodiment variant according to the invention, in which a three-dimensional luminous object 12 is arranged in the filter 3 of the filter cigarette 1, preferably in the form of a luminous ball. The three-dimensional luminescent object 12 may consist in its entirety of luminescent material, or its surface may be sprayed or impregnated with a fluorescent substance. The three-dimensional luminescent object 12 may be comprised of an encapsulation and filler medium, wherein either the encapsulation medium or the filler medium contains a luminescent material. The filler medium may also contain other materials, for example, liquid fragrance or flavor materials that are released when the encapsulation is broken. Such capsules with a flavourant material in the filter are known from the prior art, and they may therefore be provided with a luminescent material according to the present invention. However, the three-dimensional light object 12 is preferably not crushable, i.e. not a perfume capsule but is provided as a dimensionally stable element, which is used as a design or security feature.

The layer structure of figure 9 shows a transparent or at least translucent filter portion 13 containing a light emitting object 12. The filter wrapper 4 has a transparent or at least translucent central portion 9 which allows the emitted light to pass through to the outside. The mouthpiece enveloping material 5 also has a transparent or at least translucent middle portion 9, which allows the luminescent light to penetrate outwards.

Fig. 10 shows a tenth embodiment variant according to the invention, in which three-dimensional light-emitting objects 12 are also arranged in the filter 3 of the filter cigarette 1. The layer structure of the filter cigarette comprises a transparent or at least translucent filter portion 13 (which contains the luminescent object 12), a filter wrapper 4 (which is itself transparent or at least translucent), and a mouthpiece wrapper 5 (which has an opening 8) such that the luminescent light from the luminescent object 12 can penetrate outwards.

Fig. 11 shows an eleventh embodiment variant according to the invention, in which the mouthpiece cover 5 has an opening 8 and a luminescent coating 2 or a luminescent body 12 is applied to the filter cover 4 or the filter cover 4 itself contains a luminescent material. The luminescent coating 2 may be printed as a two-dimensional image of a three-dimensional object, such as a sphere, so that it simply looks like an object is present in the filter cigarette 1.

The technical features described for the embodiment variants one to eleven according to the invention can be combined differently by the person skilled in the art within the scope of the usual measures, for example a filter cigarette 1 according to the invention can have both at least one luminescent object 12 and also at least one luminescent print 2. Furthermore, the layer structure may have at least one or more intermediate layers 8 and the individual encapsulating materials and the intermediate layers of the layer structure may each have openings 10 and/or intermediate portions 9. The at least one encapsulating material, the intermediate layer 8, and/or the intermediate portion 9 may have a luminescent print 2 on one or both sides. According to a further embodiment variant of the invention, two leakage-proof layers can be provided, i.e. layers made of materials through which these luminous materials cannot pass, for example the mouthpiece enveloping material 5 and the intermediate layer 8, each made of a plastic film or cellophane, with the luminous print 2 or luminous film arranged between the two leakage-proof layers. The layer structure prevents the transport or displacement of the luminescent and/or fluorescent or phosphorescent substance both in the direction of the interior of the cigarette and also outwardly in the direction of the cigarette surface.

Figure 12 shows a cigarette pack 14 having a luminescent print 15 and containing an inner liner 16 having a luminescent print 17. The luminescent prints 15, 17 may be applied in a planar manner as characters, codes, shapes, patterns, images, or to highlight the outline of the cigarette package or another print, and may be used as a security feature to improve counterfeit protection of the cigarette package.

The luminescent and/or fluorescent or phosphorescent materials and/or printing mentioned here can be used on tipping wrappers (tipping paper ), opening strips, cigarette paper, filter wrappers (plug wrap), inner liners, inserts in cigarette cartons or shoulder boxes (wrapper box), and packaging of the articles, E-cigarettes and the mentioned products and/or cigarette components.

These printed luminescent and/or fluorescent materials can be provided as security features or design elements, wherein any design element made of fluorescent material is considered a technical security feature, since it is more difficult to recognize and imitate compared to conventional printing. The security feature may also be used for prize competition, which may be made visible in the dark by printed numbers, symbols, or codes on the cigarettes or their wrapper and which the consumer can check to see if he has won. Thus, the QR code may also be used by accessing the consumer to a specialized home page after entering the code.
