Description

Fabric for white snus pouch
Description
The present invention is directed to a pouch for white snus. The pouch comprises a fabric and is at least partially coated. Furthermore, a method for producing a pouch for white snus comprising the steps of providing a fabric, providing an odorizing composition, coating at least parts of a surface of the fabric with the odorizing composition, forming a pouch from the fabric and filling white snus in the pouch, is described.
Snus is a smokeless tobacco product which is usually consumed by placement inside the lip between the lip and gums for an extended period. (Brown) snus usually comprises tobacco composition in a pouch. Often the tobacco composition is prepackaged as moist powder in small teabag-like sachets (also referred as pouches). Snus is often mildly flavored with foodgrade, bergamot, citrus, juniper berry, herbs and/or floral flavors. In contrast to snuff, the snus tobacco is usually not fermented. In its traditional form, the sachet material is moisturized during the manufacturing process. This results in a brownish appearance of the pouch.
Since the brownish pouch is often considered to appear unhygienic, so-called white snus have become popular. The white snus is usually a milder-tasting and slightly slower-release form. The main difference with respect to the traditional form is that the sachet material is not moisturized during the manufacturing process. The pouch remains dry and discoloration due to diffusion of coloring agents through the pouch material is slowed. Furthermore, even if the tobacco composition within the pouch has the same moisture content, the nicotine and flavor are passing slower through the pouch material as described in WO 2017/093941. Also nicotine pouches, which are not containing tobacco leaves are considered to be white snus.
However, due to the different composition of white snus and/or even lack of tobacco in such a composition, these products are not providing the usual odor of brown snus. Since the known tobacco odor is desired by most of the users, it is a subject matter of the present invention to provide a white snus pouch, which provide the requested odor.
Furthermore, a method for producing a pouch for white snus is requested.
It has been found that these problems could be overcome by a white snus according to claim 1 and a method according to claim 12.
A pouch suitable for a white snus according to the invention comprises a pouch comprising a fabric. Preferably the white snus comprises a carrier material and nicotine without tobacco being present. A surface of the fabric is at least partially coated with an odorizing composition comprising tobacco particles having an average size (sDso laser diffraction) < 30 pm. The odorizing composition may comprise further odorizing substances. However, the small tobacco particles have been found to be important since they provide a full tobacco odor over a long period. The tobacco particles may originate from any part of the tobacco plant, e.g. leaves, stems or roots.
Since the full tobacco odor could be provided by the pouch, the snus could comprise a nicotine source other than tobacco leaves. The snus composition could be even tobacco free.
Preferably, the average size of the tobacco particles (sDso laser diffraction) is > 1 pm, preferably > 2.5 pm, more preferably > 5 pm, most preferably > 8 pm. It has been found, that grinding of the tobacco particles to a smaller particle size could affect the odor. It is believed that some of the odorizing molecules of the leaf tobacco decompose due to the high shear energy. Furthermore, some odorizing molecules could exit too small tobacco particles during the grinding process or during a later handling process. This would result in a depletion of these odorizing molecules in the tobacco particles and an odorizing composition different with respect to the full tobacco odor. Surprisingly, it has been found that tobacco particles having such a small size and adhered to the surface of a carrier material are coloring of the pouch only a little or are even not coloring. Because of the small size, the particles are not visible to the human eye. Furthermore, the small size of the particles is preferred since these particles have shown to deliver the full tobacco odor to a user.
Tobacco particles having such a small average particle size are providing a high surface area from which odorizing molecules could leave the particle. The mean particle size of < 30 pm has been found to allow transfer of a plurality of odorizing molecules homogeneously over a long time period. Thus, a full tobacco odor could be maintained. The particle size allows migration of bigger and smaller molecules from an internal volume of the particles to their surface from which these molecules could pass over to the packaging volume and - after opining of the packaging - could be sensed by a user. It has been shown that the mean size of the tobacco particles provides an optimal volume to surface ratio, due to which a mixture with widely constant ratios of odorizing molecules leaves the particles over a long time interval.
The tobacco particles having an average size < 30 pm may be adhered on an inert carrier. The inert carrier may be a part of the fabric of the pouch. However, the inert carrier could also be a different material.
The term “inert”, especially in combination with the word “carrier”, means in the context of the present invention, that a first substance does not chemically interact with the second substance (e.g. the carrier). An inert carrier is preferably inert with respect to the surrounding environment. Thus, the carrier itself remains chemically unchanged when contacted by other compounds of the snus, the snus packaging and/or the odorizing composition. However, “inert” does not mean that no interaction between the snus composition, the packaging and/or the odorizing composition and the (inert) carrier is possible. Especially physical interactions like energy transfer (e.g. friction) is possible. Also, other physical properties of the inert material (e.g. the carrier) could change due to such an interaction. For example, its shape or (specific) surface area could change because of application of an external force.
As described below, in a preferred embodiment of the invention odorizing molecules are released from the tobacco particles upon an activation signal (e.g. friction or temperature change). Also, the resulting change of at least one physical property of the inert carrier material is possible and is not excluded by the term “inert”.
In a preferred embodiment, a form of the carrier material is selected from a group comprising fibers, filtering material, fiber tow, staple fibers, randomly oriented staple fibers, sheets, paper sheet, folded paper, rolled paper, crimped paper, matrix material, sponge type, ceramic material, fleece, multiple tubes, single tube, granulate, spherical particles, cubes, cuboids and parallelepipeds. These kinds of carrier materials have been found advantageous, since they are commonly used for other purposes in the production of tobacco products. Thus, it is known in the art, how to handle these materials. Furthermore, these materials could be handled with common handling machines.
Preferably, the average size of the tobacco particles (sDso laser diffraction) is > 1 pm, preferably > 2.5 pm, more preferably > 5 pm, most preferably > 8 pm. It has been found, that grinding of the tobacco particles to a smaller particle size could affect the odor. It is believed that some of the odorizing molecules of the leaf tobacco decompose during the grinding process due to the high shear energy. Furthermore, some odorizing molecules could exit too small tobacco particles during the grinding process or during a later handling process. This would result in a depletion of these odorizing molecules in the tobacco particles and an odor different with respect to the full tobacco odor. Furthermore, it has been found, that larger particles could maintain the full tobacco odor over a longer period during storage and/or consumption of the snus.
Since the small tobacco particles provide a full tobacco odor over a long period, the total amount of the odorizing composition could be very low. In a preferred embodiment, the amount of the tobacco particles is less than 2 % (weight/weight) of the pouch, preferably less than 1 %, more preferably in the range of 0.01 to 0.1 %. All the previous mentioned percentages are defining the weight of the tobacco particles with respect to the weight of the pouch. Also, in the following, any percentages should be understood in this manner, if not explicitly specified differently. It has been shown, that an amount of the tobacco particles in the above-mentioned rage is high enough to provide the full tobacco odor over a long period.
The odorizing composition itself preferably comprises 0.05 - 60 % (weight/weight) of tobacco particles. Preferably, the odorizing composition comprises 1 - 50 %, more preferably 2 - 30 % of tobacco particles. It has been found that these percentages are sufficient to provide the desired tobacco odor over a long period when applied only on parts of the pouch.
According to the invention, the odorizing composition is an ink. Such an ink may comprise a liquid and/or a coloring agent. Application of the odorizing composition together with a coloring substance facilitated the production process, since the printing and the odorizing composition could be applied in a single step, preferably by common printing machines. The liquid is preferably selected from a group comprising water, alcohol, propylene glycol and glycerin.
In a preferred embodiment, the odorizing composition is applied in a predetermined pattern on the carrier. This embodiment allows application of signs, which could be recognized by the user. Preferably the predetermined pattern is a symmetrical geometrical pattern, a letter, a symbol, a logo and/or a trademark. Thus, the product could be distinguished from other products easily. This embodiment is especially preferred in combination with the above- mentioned embodiment in which the odorizing composition is part of an ink.
Preferably the odorizing composition is located only on parts of the surface of the fabric, preferably in a predetermined pattern. The pattern could include information relating to the product, its usage and/or its production. Preferably the pattern is selected from a group comprising a letter, a logo, a symmetric geometrical pattern or shape, a company logo, a company name, a trademark and a machine-readable code, wherein the machine-readable code is preferably selected from a group comprising EAN, UPC, IAN, JAN, ITF, 2/5i, Code39, Code93, Codabar, Code128 Codablock, Code49, PDF417, QR-Code, DataMatrix, MaxiCode, Aztec-Code, JAB-Code, Han Xin-Code, Dot-Code A, Snowflake code, BeeTagg Composite-Code and RM4SCC. Such a pattern facilitates recognition of a pouch by a user or by handling machines. Thus, handling failures or misuse could be avoided or reduced.
To increase the recognizability of the odorizing composition, it is preferred that the contrast between surface of the fabric coated with the odorizing composition and the surface of the fabric which is not coated with the odorizing composition is at least of grade C, preferably grade B, more preferred grade A measured according to ISO/IEC 15416:2016 or ISO/IEC 15415:2011. Preferably the odorizing composition comprises substances selected from a group comprising solvents, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate matter, fluorescents, water, humectant, glue, dyes and resins. These substances increase visibility of the odorizing composition and/or facilitate its handling (e.g. by adjusting the viscosity).
The viscosity of the odorizing composition is preferably > 20 to < 500 dPas, preferably > 40 and < 400 dPas, more preferably > 50 and < 350 dPas. These viscosities are measured with a falling-rod viscometer at 25°C. Also, in the following, any values relating to the viscosity should be understood in this manner, if not explicitly specified differently. Compositions of this viscosity are easy to handle and allow application I a predetermined pattern with common printing machines.
Preferably the odorizing composition has a density of 0.5 g/cm3 to 2.5 g/cm3, preferably 0.7 g/cm3 to 2.0 g/cm3, more preferably 0.8 g/cm3 to 1.5 g/cm3. Compositions of this density are easy to handle and could be processed with common machines.
Preferably, releasing of the odorizing molecules from the odorization composition is initiable by an activation signal. This embodiment is advantageous, since releasing of the odorizing molecules could be triggered by the user. Thus, depletion of odorizing molecules from the odorization composition during storage (when no odor is required), could be avoided.
Preferably, the activation signal is given when the pouch is handled by a user. For example, the activation signal could be triggered automatically when the packaging is opened and/or when a pouch is taken out of the packaging.
In a preferred embodiment, the activation signal is selected from a group comprising temperature change, human contact, friction, mechanical strain, exposure to visible light, humidity change, pressure change, electric signal, UV-light, IR-radiation, light and electromagnetic radiation. Thus, it is possible, that releasing of the odorizing molecules from the odorization device is initiated when the packaging is opened or when a pouch is taken out of the packaging. The process of opening the packaging can for example result in a change of temperature, humidity or pressure and/or in exposure to electromagnetic radiation such as visible light, UV-light or IR-radiation. Any of these signals could be used for releasing the odorizing molecules from the odorization composition. For example, a bond (chemical bond, van-der-Waals bond and/or London force) between the odorizing molecules and the pouch could be cleaved thermally or due to irradiation. Alternatively or in addition thereto, also mechanical stress due to the process of taking a pouch out of the packaging could initiate releasing of the odorizing molecules. In a preferred embodiment, the odorizing molecules are released due to the mechanical force caused by the movement of the pouch when taking a snus out of the packaging.
In a preferred embodiment, the odorizing composition is arranged in a closed environment. This closed environment could for example be opened by application of mechanical force, which may be caused by the movement of the snus when taken out of the packaging. Preferably, the closed environment is a capsule. This is advantageous, since a capsule could be handled easily and different capsules are known, which could be opened by different activation signals. More preferably the capsule is a microcapsule. Microcapsules are advantageous since little amounts of the odorizing composition could be encapsulated separately from each other in different microcapsules, from which only a single microcapsule or a small number of microcapsules is opened when an activation signal is given. This allows conservation of odorizing composition over a long period in the remaining (unopened) microcapsules.
Preferably, the odorization composition is located on an outer surface of the pouch. This embodiment is preferred since the odorization composition is prone to an activation signal, which is given when the packaging is opened. For example, the activation signal could be (visible) light which enters into a packaging upon opening.
Preferably, the odorization composition is located at a position of the pouch which is prone to mechanical strain and/or friction caused by taking the snus out of a container. The energy provided by the user due to mechanical strain and/or friction could serve as activation signal.
Preferably, the small tobacco particles also provide a flavor during consumption of a snus comprising a pouch as described above. Due to the high relative surface area of the small tobacco particles (with respect to their volumes) the tobacco flavor could reach the surface easily and exit the particle. Preferably, the tobacco flavor is extractable from the tobacco particles by saliva. This embodiment is preferred since undesired loss of flavor during storage could be limited. Preferably, releasing of the flavoring molecules from the tobacco particles is initiable by an activation signal. This embodiment is advantageous, since releasing of the flavoring molecules could be triggered by the user. Thus, depletion of flavoring molecules from the tobacco particles during storage could be avoided. Preferably, the activation signal is selected from a group comprising temperature change, mechanical strain, humidity change, change of the pH value, contact to a liquid, contact to water and contact to saliva. Thus, it is possible, that releasing of the flavoring molecules from the small tobacco particles is initiated when the snus is used. Preferably, the extraction of the flavoring molecules from the small tobacco particles is initiated by one or more proteins of the saliva. Preferably, the tobacco particles remain adhered to the pouch or the inert carrier when contacted by saliva.
In a preferred embodiment, the amount (weight) of the nicotine source in the snus is at least 5-fold, preferably > 7-fold, > 10-fold or even > 20-fold higher than the amount of the small tobacco particles. It has been found, that even small amounts of the small tobacco particles are suitable to provide the full tobacco flavor and/or odor to a user, even if large amounts of the nicotine source are present. The above-mentioned ratios are preferred since a cheap and/or tobacco free nicotine source could be used and the full tobacco flavor/odor could be maintained anyway. High ratios between the amount of the nicotine source in the snus composition and the amount of the small tobacco particles are especially preferred if legal restrictions or high taxes limit the acceptance of tobacco leaves as nicotine source in the snus composition.
Preferably, the tobacco particles adhered to the inert carrier are obtained by grinding of a tobacco source. More preferably, the grinding process is performed at reduced temperature of < 15°C, preferably <12°C, more preferably a temperature of 0° to 10°C. The lower temperature avoids decomposition of odorizing molecules during grinding.
To avoid decomposing of odorizing molecules during the grinding process, it has been found advantageous, to reduce the viscosity of the grinding composition. This could be achieved by adding a solvent to this composition. Such a solvent (or “dispersion medium”) is preferably selected from a group comprising water, monovalent alcohols, polyvalent alcohols, sugar alcohols, sugars and polyvalent alcohol esters. By using such a dispersion medium, the average particle size of the leaf tobacco can be adjusted to the desired value, without significant changes of the odor. More preferably the one or more dispersion medium is selected from a group comprising water, monovalent alcohol, monovalent aliphatic alcohol, methanol, ethanol, 1-propanol, 2- propanol, 1-butanol, 2-butanol, 2-methyl-1 -propanol, 2,2-dimethylethanol, cyclohexanol, monovalent alcohol having an aromatic substituent, benzyl alcohol, monovalent alcohol containing one or more halogen element monovalent alcohol having one or more ether bond, polyvalent alcohol, glycerol, propylene glycol, sugar alcohol, sorbitol, maltitol, xylitol, erythritol, lactitol, sorbitan, xylose, arabinose, mannose, trehalose, sugar, lactose, sucrose, coupling sugar, glucose, enzyme-saccharified starch syrup, acid-saccharified starch syrup, maltose starch syrup, maltose, isomerized sugar, fructose, reduced maltose, reduced starch syrup, honey, polyvalent alcohol ester, fatty acid polyvalent alcohol ester and fatty acid triglyceride.
Preferably, the ratio of the tobacco particles in a grinding dispersion is > 0,5 % (w/w), preferably > 1 % (w/w), > 2 % (w/w) or > 5 % (w/w), more preferably > 10 % (w/w), most preferably > 20 % (w/w) and < 95 % (w/w), preferably < 90 % (w/w), < 80 % (w/w) or < 70 % (w/w), more preferably < 60 % (w/w), most preferably < 50 % (w/w). It has been found that these ratios allow grinding of the leaf tobacco to the desired average particle size in most of the solvents without significant loss of odor.
Preferably, the snus comprises further additives. Adding additional substances (or additives) the snus could be adapted to individual preferences of different users. Preferably, the snus comprises at least 2, preferably > 3, more preferably > 4, more preferably > 5, more preferably > 6 further substances. Preferably, these additives are selected from a group comprising a filler material, water, humectants, cellulose, glycol, propylene glycol, glycerol, sweetener, sugar, sugar alcohol, gum, pH-adjusting agent, puffer agent, ammonia, ammonium carbonate, potassium carbonate, sodium carbonate, calcium carbonate, preservative, salt.
In a preferred embodiment, the tobacco particles are pasteurized. This could increase the shelf life of the pouch and/or snus. Preferably, the sterilization (the terms “pasteurized” and “pasteurization” are used synonymously with the terms “sterilized” and “sterilization”) follows the grinding process. In a preferred embodiment, the sterilization process is performed at elevated temperature. The higher temperature could be used to get rid of the solvent (or dispersion medium) added during the grinding process. The sterilization process could also include the process of adhering the tobacco particles on the carrier.
A further aspect of the invention is a method for manufacturing a pouch for a white snus comprising the steps of: providing fabric, providing an odorizing composition comprising tobacco particles having an average size < 30 pm,
- coating at least parts of a surface of the fabric with the odorizing composition,
- forming a pouch from the fabric and
- filling white snus in the pouch.
This method allows production of a pouch for a white snus in an easy manner. Such a pouch provides a desired tobacco odor even if this tobacco is not the main nicotine source of the snus or the snus composition does not contain tobacco. Thus, this method allows selection of a desired tobacco odor independently from an eventually present odor of the nicotine source. Even snus compositions which originally do not provide a tobacco flavor (e.g. because the nicotine does not derive from tobacco), could be adjusted easily to provide a desired tobacco odor.
Preferably, the method further comprises the step of coating parts of a surface of the fabric with the odorizing composition by printing. In this embodiment, the odorizing composition is preferably part of an ink.
Preferably, the printing process is performed by conventional printing machinery. The printing could be applied by inline printing or offline printing.
Preferably, the application of the odorizing composition is performed together with the application of a coloring substance. This facilitates the production process, since a printing and the odorizing composition could be applied in a single step, preferably by common printing machines. Such an ink comprising the odorizing composition and a coloring substance is preferably based on a liquid selected from a group comprising water, alcohol, propylene glycol and glycerin. Preferably, the printing step comprises printing a pattern which includes information relating to the product, its usage and/or its production. Preferably, a pattern printed, which is selected from a group comprising a letter, a logo, a symmetric geometrical pattern or shape, a company logo, a company name, a trademark and a machine-readable code, wherein the machine-readable code is preferably selected from a group comprising EAN, UPC, IAN, JAN, ITF, 2/5i, Code39, Code93, Codabar, Code128 Codablock, Code49, PDF417, QR-Code, DataMatrix, MaxiCode, Aztec-Code, JAB-Code, Han Xin-Code, Dot-Code A, Snowflake code, BeeTagg Composite-Code and RM4SCC.
In a further preferred embodiment, the odorizing composition is part of a glue and a surface of the fabric is coated with this glue and subsequently fold on other parts of the fabric for forming the pouch. This process is very easy since the application of the odorizing composition and the glue could be performed in a single step.
Preferably, the method comprises the step of pasteurizing the tobacco particles adhered on an inert carrier. The pasteurization step is preferably performed at elevated temperature. This higher temperature could also be used to reduce or remove a solvent from the odorizing composition. Reduction or removal of the solvent may also result in adherence of the tobacco particle on a surface of the inert carrier. Thus, the steps of pasteurization and adhering the tobacco particles on the surface of the carrier are performed simultaneously. In this context simultaneously should be understood in that the steps of pasteurization and adhering the tobacco particles on the surface of the carrier overlap each other at least partially. However, one of these steps (preferably the step of adhering the tobacco particles on the surface of the carrier (eventually including removal of a solvent)) could be finished prior the other of these steps. Preferably no further handling step is performed between these two steps.
It will be understood that the embodiments explained above are merely a first embodiment of the method and/or system of the invention. In this respect, the disclosure of the invention is not limited to these embodiments.
All the features disclosed in the application documents are claimed as being essential to the invention in so far as they are individually or in combination novel over the prior art.
