This application is a national phase application of PCT Application No. PCT/AT2017/060181, filed Jul. 20, 2017, which claims priority to Austrian Patent Application No. A 50669/2016, dated Jul. 21, 2016, both of which are incorporated by reference in their entirety.
FIELD OF THE INVENTIONThe invention relates to a tobacco product in the form of a filter cigarette with fluorescent or phosphorescent substances.
A tobacco product with fluorescent or phosphorescent substances in the sense of the present specification is a tobacco product which exhibits at least one externally visible or detectable feature upon excitation of the fluorescent or phosphorescent substance. The printing described herein is also applicable to packaging material of tobacco products, wherein this application is disclosed but not claimed within this application.
DESCRIPTION OF RELATED ARTUS2921587A shows a filter cigarette with a luminescent or phosphorescent material which is applied on the outside of the wrapper material of the filter cigarette. Which phosphorescent material is applied is not disclosed, and it is not disclosed whether or whereby a safe use of the filter cigarette is ensured.
For the safe use of a fluorescent printing in connection with a filter cigarette, it is proposed in US 2015/0090274 A1 to provide the fluorescent printing on an additional wrapper or end cap which must be removed before smoking the filter cigarette. The disadvantage is that the ready-to-use cigarette has no luminescent properties, or that additional packaging material is required on each individual filter cigarette.
For the safe use of a filter cigarette with luminescent coating, it is proposed in CN203058273U to cover the luminescent coating with a protective layer of water-based lacquer. The disadvantage is that compared to the substances of the luminescent coating, a coating with lacquer can only be produced in a dense layer in a very elaborate manner which requires a time-consuming coating with a relatively thick lacquer layer. In addition, this coating with lacquer can interact with the luminescent substances through the solvent of the protective lacquer, which can result in the attenuation of the luminous effect, or causes the luminescent substances to migrate with the solvent of the protective lacquer into deeper layers of the filter cigarette, or fine structures of the fluorescent coating become “washed out” and thus blurred. Assuming that the luminescent coating would be done with nitrocellulose lacquer, then applying the water-based protective lacquer might move the luminescent substance into the base paper or into the protective lacquer layer.
It is proposed in US 2016108293 A1 to apply a fluorescent substance with the glue or adhesive with which the individual components of the filter cigarette are glued together. In a second embodiment, it is envisioned to provide components of smoking articles with a printing which contains a fluorescent substance.
It is proposed in US 2015041345 A1 to provide the cigarette packaging with fluorescent markings. It is envisioned in one embodiment that the fluorescent substance is contained in a paper of the cigarette for labelling the cigarette box, or is applied thereto, so that the cigarette box is identifiable due to the contained cigarettes.
It is proposed in CN 105013719 A to provide products with codes to be able to identify and sort them, wherein the codes can be applied with fluorescent substances.
SUMMARY OF THE INVENTIONThe first underlying object of the invention is to make the use of fluorescent or phosphorescent substances safer on the ready-to-use tobacco product, wherein even fine structures should be easy to represent.
To achieve this object, it is proposed to transfer such fluorescent or phosphorescent substances, the use of which is recognized as safe in the food sector, into this different technical field and/or to integrate the fluorescent or phosphorescent substances into the layer structure of the tobacco product in such a way that said substances are protected against contact and other external influences.
Another underlying object of the invention is to provide the tobacco product with features that are not visible in daylight and only become visible in the dark, or can only be made visible through excitation by light of a particular wavelength.
To achieve this object, it is proposed to apply fluorescent or phosphorescent substances which are colourless, or for which the colour thereof corresponds to the substrate on which they are applied. Preferably, such substances are applied which will emit light after stimulation over a longer period of time, and which will glow in the dark after removal of the illumination and thus are visible and easier to find, wherein this effect of prolonged afterglow is generally achievable through phosphorescence. The luminous intensity is preferably selected such that the printing with the phosphorescent substances is not visible in daylight and becomes visible only in the dark or in muted light. Likewise, preferably those substances are applied which radiate only briefly or only immediately after excitation by light so that they can be made visible through illumination with UV light (black light) in the dark and after removal of the illumination with black light have no or only insignificant afterglow and thus are not visible in the dark, this effect of short-term afterglow generally being achievable through fluorescence. The luminous intensity is preferably selected such that the printing with the fluorescent substances is not visible in daylight and can be made visible with black light only in the dark or in muted light.
Both of the objects according to the invention are achieved through the use of riboflavin which is applied as, on, in, or under the yellow imitation cork (yellow base paper or printed) of the mouthpiece of filter cigarettes. Riboflavin is a yellowish substance that is used in food technology as a yellow food colourant (E101). Preferably, a riboflavin-containing lacquer is applied to a finished filter cigarette or a finished mouthpiece wrapper material as the outermost or final layer, with the advantage that no further layer is applied over the riboflavin printing which could affect it or wash it out.
Both objects according to the invention are also achieved through the use of quinine. Quinine is a colourless substance which is used in food technology as a bitter substance. Preferably, a lacquer containing quinine or a quinine derivative is applied to a finished filter cigarette or a finished mouthpiece wrapper material as the outermost or final layer, with the advantage that no further layer is applied over the quinine printing which could affect it or wash it out.
Both of the objects according to the invention can also be achieved by the use of other fluorescent or phosphorescent substances which are colourless or for which the colour in normal ambient light corresponds to the background thereof if said substances are integrated into the layer structure of the tobacco product, so that the tobacco product is reliably protected against contact with the substances. Preferably, strontium aluminate (also aluminium strontium oxide), particularly preferably strontium aluminate doped with europium, is used. Depending on the structure thereof, strontium aluminates, or strontium aluminates doped with europium, comprise colourless substances with particularly bright or particularly long-lasting luminous intensity.
An advantage over the prior art is the fact that the tobacco products in question are absolutely safe in use or consumption, and that the appearance of the tobacco product in daylight is unchanged compared to the conventional tobacco product.
Use according to the invention comprises the application of the fluorescent or phosphorescent substances to enable rapid detection of the tobacco product in the dark or for the application of the fluorescent or phosphorescent to increase the protection against counterfeiting, identifiability, or information content of the tobacco product.
In a preferred embodiment according to the invention, the fluorescent or phosphorescent substances are dissolved in a suitable solvent and then mixed with lacquer or dispersed in lacquer and subsequently applied to or printed onto the tobacco product or onto one of the layers thereof. The solvent and the lacquer are preferably colourless and preferably transparent. The lacquer could also be coloured with pigments or printing inks, whereby, however, the effect or luminous intensity of the fluorescent or phosphorescent substances will be attenuated. The application or the printing of the lacquer provided with fluorescent or phosphorescent substances takes place, for example, in the gravure printing process or another known printing method. The lacquer is preferably nitrocellulose lacquer which has been proven for use on mouthpiece wrapper materials.
In a further preferred embodiment according to the invention, a film having the fluorescent or phosphorescent substances, in particular a film doped with fluorescent or phosphorescent substances, is provided on or in the tobacco product. The fluorescent or phosphorescent substances are preferably enclosed in or integrated into the polymer framework of a plastic film.
In a further preferred embodiment according to the invention, a three-dimensional object comprising the fluorescent or phosphorescent substances is placed inside the tobacco product.
Exemplary embodiments according to the invention of the claimed filter cigarette are illustrated below with reference to drawings:
The drawings of the figures are not to scale, in particular the layer thicknesses in the sectional images to illustrate the layer structure. In particular, the layer thickness of the luminous printing 2 is shown disproportionately thick to make it recognisable. Since the printing is usually available with a layer thickness in the μm range, this would not be visible in the layer structure true to scale. The term luminescence is used in the sense of photoluminescence as a collective term for phosphorescence and fluorescence. The “luminous” in the terms luminous printing, luminescent film, and luminous object refers to illumination in the form of luminescent light which is exposed through excitation with light of a suitable wavelength by the effect of phosphorescence and/or fluorescence.
The layer structure of
The technical features illustrated in embodiments one through eleven according to the invention can be differently combined within the scope of expert practice, for example a filter cigarette 1 according to the invention can have both at least one luminous object 12 and at least one luminous printing 2. In addition, the layer structure can have at least one or more intermediate layers 8, and the individual wrapper materials and intermediate layers of the layer structure can each have openings 10 and/or intermediate sections 9. At least one wrapper material, one intermediate layer 8 and/or one intermediate section 9 can have a luminous printing 2 on one or both sides. A further embodiment according to the invention can provide two dense layers, i.e., layers of materials through which the luminescent substances cannot pass, for example, a mouthpiece wrapper material 5 and an intermediate layer 8 can be provided, each formed of plastic film or cellophane, wherein the luminous printing 2 or a luminous film is arranged between the two dense layers. This layer construction prevents a transport or movement of the luminescent or fluorescent or phosphorescent substances both in the direction of the cigarette interior as well as outward in the direction of the cigarette surface.
The luminescent or fluorescent or phosphorescent substances or printings mentioned herein can be applied to mouthpiece wrapper material (tipping paper, mouthpiece covering paper), tear-off strips, cigarette paper, filter wrapper material (plug wrap/filter wrapper paper), an inner liner, feeders & inlays in cigarette packs or shoulder boxes, on or on e-cigarettes, and on packaging for the products or cigarette components mentioned.
The printed luminescent or fluorescent substances can be present either as security features or design elements, wherein each design element made of fluorescent materials is to be regarded as a technical security feature, since this is difficult to recognise and imitate in contrast to conventional printing. Security features can also be used for sweepstakes by printing numbers, symbols, or codes on cigarettes, or on the packaging material thereof, that can be made visible in the dark and the consumer can verify having won. QR codes can also be used so that the consumer can be forwarded to a specific homepage after reading in the code.
