FIELD
[0001] The present disclosure relates to a smokeless article. This disclosure also relates to a method of manufacturing the smokeless article, a use of the smokeless article for oral delivery, a kit comprising the smokeless article, and related uses.
BACKGROUND
[0002] Smokeless articles are placed in the mouth where saliva extracts the soluble element from the content contained within. Typically, the smokeless article is placed in the oral cavity, sublingually or in the oral vestibule (between the teeth and lips/cheeks). The user may assist extraction by oral manipulation, such as by chewing and/or sucking or pressing on the outside of the mouth to squeeze the pouch.
[0003] One example of a smokeless article is a snus pouch, which contains a content (snus) comprising tobacco.
[0004] Snus and snus pouches may have appealing appearances to some users. Other users may prefer tobacco-free alternatives.
SUMMARY
[0006] In a first aspect, the present disclosure provides to a smokeless article for oral use. In some examples, the smokeless article may be an oral nicotine delivery (OND) article.
[0007] In some examples, the smokeless article may comprise a pouch enclosing a content. In some examples, the content may comprise a cellulosic material, wherein the cellulosic material comprises one or more selected from the group consisting of: coffee grinds, corn silk, cocoa nibs, lapsang tea, vanilla rooibos tea, seaweed, carob powder, and a combination of star anise with one or more selected from the group consisting of: coffee grinds, corn silk, cocoa nibs, lapsang tea, vanilla rooibos tea, seaweed, and carob powder.
[0008] In some examples, the content may comprise a cellulosic material, wherein the cellulosic material is one or more selected from the group consisting of: coffee grinds, corn silk, cocoa nibs, lapsang tea, vanilla rooibos tea, seaweed, carob powder, and a combination of star anise with one or more selected from the group consisting of: coffee grinds, corn silk, cocoa nibs, lapsang tea, vanilla rooibos tea, seaweed, and carob powder.
[0009] A content comprising the cellulosic material defined herein may, through the perception of a user, resemble the snus of a snus pouch. A pouch enclosing a content comprising the cellulosic material defined herein may, through the perception of a user, resemble a snus pouch i.e. may resemble a pouch containing a content wherein the content is snus. References herein to the resemblance of a pouch to a snus pouch should be considered to encompass resemblance of the content to snus. For example, the pouch of the present disclosure may have at least one sensory characteristic which resembles a snus pouch, such as its appearance, texture, odour and/or taste, and the content of the present disclosure may have at least one sensory characteristic which resembles snus, such as its appearance, texture, odour and/or taste.
[0010] In some examples, the pouch described herein has at least two sensory characteristics which resemble a snus pouch, such as two or more of appearance, texture, odour and taste. For example, the pouch may resemble a snus pouch in terms of at least its appearance and texture, or its appearance and odour, or its appearance and taste, or its texture and odour, or its texture and taste, or its odour and taste. In some examples, the pouch may resemble a snus pouch in terms of at least its appearance and texture, or in terms of its odour and taste.
[0011] In some examples, the pouch described herein has at least three sensory characteristics which resemble a snus pouch, such as three or more of appearance, texture, odour and taste. For example, the pouch may resemble a snus pouch in terms of at least its appearance, texture and odour, or its appearance, texture and taste, or its appearance, odour and taste, or its texture, odour and taste.
[0012] In some examples, the pouch described herein has at least four sensory characteristics which resemble a snus pouch, such as in terms of its appearance, texture, odour and taste.
[0013] In some examples, the pouch has as many sensory characteristics resembling a snus pouch as possible.
[0014] In some examples the pouch herein may have sensory characteristics resembling a snus pouch because the cellulosic material of the content has sensory characteristics resembling snus. For example, the cellulosic material may resemble at least one, at least two, at least three or at least four sensory characteristics of snus (e.g., at least one, two three or four of the appearance, texture, odour and taste of snus).
[0015] "Snus" will be familiar to the skilled person in this technical field and is a smokeless, powdered form of tobacco intended for oral delivery. Snus may be provided in loose form or in a pouch, e.g., a conventional snus pouch. Snus is typically made from ground tobacco and additives such as water and salt. "Snus pouch" is used herein to refer to a pouch containing snus.
[0016] The resemblance of a pouch of the present smokeless article to different sensory characteristics of snus pouches may be measured qualitatively. For example, a user, or preferably a group of users, such as at least two users (e.g., from two to five users), will score the sensory characteristics of a smokeless article herein in terms of how well it resembles a smokeless article comprising a snus pouch based on observation with the naked eye (i.e., appearance), hand-feel and/or mouthfeel (i.e., texture), smell (i.e., odour) and flavour (i.e., taste). In a group sample, an average score can be taken for each sensory characteristic to determine the resemblance of the pouch of the smokeless article to a snus pouch.
[0017] The resemblance of a pouch herein to different sensory characteristics of a snus pouch may also be measured quantitatively. For example, the resemblance of a pouch herein to a snus pouch may be determined based on the similarity of their RGB values determined using a colourimeter, such as using a colourimeter model PCE XXM20. Measurements may be taken in different colour spaces (such as CIE LAB, XYZ, LCh, and LUV) and converted to RGB values using standard conversions and commonly available online tools.
[0018] In some examples, the smokeless article comprises a pouch enclosing a content. In some examples, the pouch of the smokeless article defines an internal volume in which the content resides. In some examples, the pouch is sealed, and in this way completely encloses the content. Such enclosing may mean that the content cannot leave the pouch when the smokeless article is not in use, for example when the smokeless article is in storage or transit. Such enclosing may mean that the content cannot leave the pouch when the smokeless article is in use, for example all or part of the content of the smokeless article does not transfer into or scatter in the oral cavity. Such enclosing may mean that the content cannot leave the pouch when the smokeless article is, and is not, in use.
[0019] In some examples, the pouch may be formed from one or more materials. In some examples, the pouch may be formed from one or more materials chosen from fibre, paper, cloth and fabric. In some examples, the pouch may be formed from one or more polymeric materials. In some examples, the polymeric material may be selected from one or more of hydroxypropyl cellulose (HPC), hydroxypropyl methylcellulose (HPMC), polyvinyl alcohol (PVOH), polyvinylpyrrolidone (PVP), polyethylene oxide (PEO) hydroxyethyl cellulose (HEC), polyethylene glycol (PEG), pullulan, sodium alginate, xanthan gum, tragancanth gum, guar gum, acacia gum, arabic gum, polyacrylic acid, maltodextrin, methylmethacrylate copolymer, carboxyvinyl copolymers, starch and gelatin.
[0020] In some examples, the pouch may be formed by folding a single sheet on itself, or by bringing two or more sheets together and sealing the edges. In some examples, the edges may first be partially sealed to provide an open pouch in which the content may be placed, before later completely sealing the pouch closed after the content is placed in the pouch. The sheets may be the same thickness or different thicknesses.
[0021] In some examples, the pouch is porous. In some examples, at least 50% of the pores have a diameter of at least 50 µm, such as at least 75 µm, at least 100 µm or at least 125 µm, based on the total number of the pores (wherein the total number of pores is 100%). In some examples, at least 50% of the pores have a diameter of up to 200 µm, such as up to 175 µm, up to 150 µm or up to 125 µm, based on the total number of the pores (wherein the total number of pores is 100%). In some examples, any combination of the foregoing may be combined to form a suitable range for the diameter of at least 50% of the pores, such as between 50 µm and 200 µm, between 100 µm to 175 µm, or 125 µm or 150 µm. In some examples, at least 50% of the pores have a diameter of at least 100 µm. In some examples at least 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or 100% of the pores have such diameters, based on the total number of pores.
[0022] Methods of measuring pore diameter will be known to the skilled person and include, for example, using electron microscopy techniques. Pore diameter here may refer to a mean average pore diameter based on the average pore diameter selected from a sample of pores in the water-permeable layer. The skilled person will be aware of a suitable sample size required to obtain a reliable mean average, which may, for example, 50, 100 or 200 randomly chosen pores.
[0023] In some examples, the material from which the pouch is comprised may be coloured. In some examples, the material from which the pouch is comprised is partially or completely coloured by a colourant. In some examples, the pouch may additionally or alternatively include markings such as brand logos and text. Such colour or markings may affect identifiability.
[0024] In some examples, the cellulosic material comprises one or more of coffee grinds, corn silk, and cocoa nibs. In some examples, the cellulosic material is one or more of coffee grinds, corn silk, and cocoa nibs. Use of these cellulosic materials may increase the perception by users that the pouch resembles at least one sensory characteristic of a snus pouch, or at least two sensory characteristics of a snus pouch.
[0025] In some examples, the cellulosic material comprises one or more of coffee grinds and corn silk. In some examples, the cellulosic material is one or more of coffee grinds and corn silk. Use of these cellulosic materials may increase the perception by users that the pouch resembles at least one sensory characteristic of a snus pouch, such as at least two sensory characteristics of a snus pouch. In some examples, the at least two sensory characteristics include appearance and texture.
[0026] In some examples, the cellulosic material comprises coffee grinds. In some examples, the cellulosic material is coffee grinds. Use of this cellulosic materials may increase the perception by users that the pouch resembles at least one sensory characteristic of a snus pouch, such as at least two, three or four sensory characteristics of a snus pouch. In some examples, the at least four sensory characteristics of a snus pouch include appearance, texture, odour and taste.
[0027] In some examples, the cellulosic material comprises one or more selected from the group consisting of: corn silk, seaweed and carob powder. In some examples, the cellulosic material is one or more selected from the group consisting of: corn silk, seaweed and carob powder. Use of these cellulosic materials may increase the perception by users that the pouch resembles at least one sensory characteristic of a snus pouch.
[0028] In some examples, the cellulosic material is or comprises one or more selected from the group consisting of: corn silk and carob powder. Use of these cellulosic materials may increase the perception by users that the pouch resembles at least one sensory characteristic of a snus pouch, such as at least two sensory characteristics.
[0029] In some examples, the seaweed in the content comprises at least one of dulse seaweed and kombu seaweed. In some examples, the seaweed in the content is at least one of dulse seaweed and kombu seaweed. Suitable dulse and kombu seaweeds may include MARA seaweed dulse and MARA seaweed kombu.
[0030] In some examples, the cellulosic material content is at least 10 wt%, at least 20 wt%, at least 30 wt%, at least 40 wt%, at least 50 wt%, at least 60 wt%, at least 70 wt%, at least 80 wt%, at least 90 wt%, at least 95 wt%, or at least 97 wt% of the total weight of the content (wherein the total weight of the content is 100 wt%).
[0031] In some examples, the cellulosic material content is no more than 99 wt%, 95 wt%, 90 wt%, 80 wt%, 70 wt%, 60 wt%, 50 wt%, 40 wt%, 30 wt%, 20wt%, or 10 wt% of the total weight of the content.
[0032] In some examples, any suitable combination of the above may be applied to obtain an appropriate range. For example, the cellulosic material may be between 10 wt% to 99 wt%, 20 wt% to 90 wt%, 30 wt% to 70 wt%, 40 wt% to 60 wt%, or 50 wt% to 99 wt%.
[0033] In some examples, the content comprises a combination of cellulosic materials, for example a combination of two or more of coffee grinds, lapsang tea, vanilla rooibos tea, seaweed, corn silk, cocoa nibs, carob powder, and star anise. Combining more than one cellulosic material may affect the perception of the pouch to a user. For example, combining more than one cellulosic material may alter (for example, may improve) the resemblance of the pouch to a snus pouch perceived by a user in terms of at least one sensory characteristic, and typically more than one sensory characteristic. By choosing an appropriate combination of cellulosic materials, it may be possible to adjust the content of the pouch to achieve a desired combination of sensory characteristics resembling those of a snus pouch.
[0034] In some examples, the content comprises nicotine. The content may comprise nicotine in the form of nicotine freebase, a nicotine salt(s), a nicotine complex(es), and a nicotine solvate(s), or mixtures thereof. In some examples, nicotine salt is selected from the group consisting of nicotine hydrochloride, nicotine dihydrochloride, nicotine monotartrate, nicotine ditartrate, nicotine ditartrate dihydrate, nicotine sulfate, nicotine zinc chloride monohydrate, nicotine salicylate and mixtures thereof.
[0035] In some examples, the content comprises nicotine in an amount of from 0.3 wt% to 2 wt%, from 0.4 wt% to 2 wt%, from 0.5 wt% to 2 wt%, from 0.5 wt% to 1.9 wt%, from 0.8 wt% to 1.8 wt%, from 1 wt% to 1.6 wt%, from 1.2 wt% to 1.6 wt%, or from 1.3 wt% to 1.5 wt%, based on the total weight of the content.
[0036] In some examples, the total nicotine content per pouch is at least 1 mg, at least 2 mg, at least 3 mg, at least 4 mg, at least 5 mg, at least 6 mg, at least 7 mg, at least 8 mg, at least 9 mg, at least 10 mg, at least 11 mg, at least 12 mg, at least 13 mg, at least 14 mg, at least 15 mg, at least 16 mg, at least 17 mg, at least 18 mg, at least 19 mg, or at least 20 mg.

[0050] In some examples, the smokeless article has a length of at least 10 mm, at least 20 mm, at least 30 mm, at least 40 mm, at least 50 mm, at least 60 mm, at least 70 mm, at least 80 mm, at least 90 mm, or at least 100 mm.
[0051] In some examples, the smokeless article has a length no more than 100 mm, no more than 90 mm, no more than 80 mm, no more than 70 mm, no more than 60 mm, no more than 50 mm, no more than 40 mm, no more than 30 mm, no more than 20 mm, or no more than 10 mm.
[0052] In some examples, the smokeless article has a width of at least 10 mm, at least 11 mm, at least 12 mm, at least 13 mm, at least 14 mm, at least 15 mm, at least 20 mm, at least 30 mm, at least 40 mm, or at least 50 mm.
[0053] In some examples, the smokeless article has a width no more than 50 mm, no more than 40 mm, no more than 30 mm, no more than 20 mm, no more than 15 mm, no more than 14 mm, no more than 13 mm, no more than 12 mm, no more than 11 mm, or no more than 10 mm.
[0054] In some examples, the smokeless article has a depth of at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm, at least 10 mm, at least 11 mm, at least 12 mm, at least 13 mm, at least 14 mm, at least 15 mm, or at least 20 mm.
[0055] In some examples, the smokeless article has a depth of no more than 20 mm, no more than 15 mm, no more than 14 mm, no more than 13 mm, no more than 12 mm, no more than 11 mm, or no more than 10 mm.
[0056] In some examples, the smokeless article has a length of about 30 mm. In some examples the smokeless article has a length of about 28 mm. In some examples, the smokeless article has a length of about 26 mm. In some examples the smokeless article has a width of about 12mm. In some examples the smokeless article has a width of about 10 mm. In some examples the smokeless article has a width of about 8 mm. In some examples the smokeless article has a depth of about 5 mm. In some examples the smokeless article has a dept of about 4 mm. In some examples the smokeless article has a depth of about 3 mm. Dimensions may be measured using any suitable optical measurement method.
[0057] In some examples, the smokeless article may have an active lifetime of about 20 minutes to about 60 minutes after being placed in the mouth. In some examples, the smokeless article has an active lifetime of about 25 minutes to 50 minutes after being placed in the mouth. In some examples, the smokeless article has an active lifetime of about 30 minutes to about 45 minutes after being placed in the mouth. As used herein, the term "active lifetime" is intended to refer to the amount of time after being placed in the mouth that the smokeless article provides the user with a perceptible taste and/or physiological experience. In examples where the smokeless article comprises nicotine, the active lifetime may be defined as the in-use period of time within which 90 wt% of the available nicotine is released. In other words, the active lifetime may be the duration of time from insertion into the oral cavity for 90 wt% of the total amount of nicotine that is capable of being released during normal use to dissolve into the user's saliva and /or enter the user's bloodstream. It will therefore be appreciated that the active lifetime of a product may vary from user to user and for a user based on oral conditions, in particular extent of salivation. Nonetheless, the skilled person is able to mimic oral conditions to determine the active lifetime in one instance, which can be used as a comparison or analysis point.
[0059] In some examples, the filler comprises one or more natural fibres. In some examples, the natural fibres comprise or are one or more of micro-crystalline cellulose, wheat fibre, bamboo fibre, apple fibre, citrus fibre, sugar cane fibre, rice fibre, psyllium fibre, potato fibre, pea fibre, and oat fibre.
[0060] Fillers may be provided to increase the volume of the smokeless article. In some examples, increasing the volume contained within the pouch may strengthen the content.
[0061] In general, suitable fillers may include calcium carbonate, calcium phosphate, corn starch, grains, lactose, polysaccharides (e.g. maltodextrin), polyols, sugars (e.g. dextrose, manitol, xylitol, sorbitol), natural fibres (e.g. non-tobacco fibres), microcrystalline cellulose, cellulose and cellulose derivatives (e.g. finely divided cellulose), lignocellulose fibres (e.g. wood fibres), jute fibres and combinations thereof. In some cases, the filler is or comprises wheat fibres. In some cases, the filler is or comprises bamboo fibres. The use of a filler is able to improve the overall mouth-feel of the smokeless article.
[0062] In some cases, the filler is or comprises micro-crystalline cellulose and one of wheat fibres or bamboo fibres.
[0063] In some cases, the filler content is no more than 70wt%, no more than 60wt%, no more than 50wt%, no more than 40wt%, no more than 30wt%, no more than 20wt%, no more than 10wt%, no more than 5wt%, or no more than 1wt% of the content, based on the total weight of the content which is 100 wt%. In some examples, the content is free of any filler (i.e., the content comprises 0 wt% filler). In these examples, the only natural fibres in the content may be those present in the cellulosic material.
[0064] Cellulosic material may improve physical integrity and may function as a natural source of substances such as, for example, biologically/pharmacologically active compounds, flavourants, pH stabilisers etc. In some examples, the cellulosic material further comprises caffeine.
[0065] The form in which the cellulosic material is provided may affect its characteristics, which may affect the perception of the smokeless article to a user. For example, the form of the cellulosic material may affect how similar a user perceives the pouch of the smokeless article to be in comparison to a snus pouch, such as in terms of at least one of the appearance, texture, odour and taste.
[0066] For example, coffee grinds are a form of coffee that may be used to provide the pouch of the smokeless article with a particularly close resemblance to a snus pouch, such as in terms of at least one of its appearance, texture, odour and taste, for example in terms of all of its appearance, texture, odour and taste. Coffee grinds are ground coffee beans and may be provided as fine, medium and coarse grinds. Coarse grinds may have larger particle sizes than medium grinds, which in turn may have larger particle sizes than fine grinds.
[0067] In some examples, particle size may be measured by sieve analysis. For example, particles having the desired particle size may be obtained by passing a population of fibres through a sieve of corresponding mesh size. For example, to obtain fibres of particle size 300 µm (i.e. an average maximum fibre length of 300 µm), a population of fibres are passed through a sieve with 300 µm diameter apertures in the mesh. In this way, fibres with a length of 300 µm or less pass through the mesh and fibres longer than 300 µm are retained by the mesh. The fibres which pass through the mesh may then be used in the smokeless article of the invention, having a particle size of 300 µm. This method may be applied, for example, to measure the particle sizes of cellulosic material and filler.

Rather, it will be apparent to those skilled in the art having the benefit of the present disclosure that the systems, apparatuses and/or methods described herein could be embodied differently and/or be practiced or carried out in various alternative ways.
[0121] Unless otherwise defined herein, scientific and technical terms used in connection with the presently disclosed inventive concept(s) shall have the meanings that are commonly understood by those of ordinary skill in the art, and known techniques and procedures may be performed according to conventional methods well known in the art and as described in various general and more specific references that may be cited and discussed in the present specification.
[0122] Any patents, published patent applications, and non-patent publications mentioned in the specification are hereby incorporated by reference in their entirety.
[0123] All examples implementing the present disclosure can be made and executed without undue experimentation in light of the present disclosure. While particular examples have been described, it will be apparent to those of skill in the art that variations may be applied to the systems, apparatus, and/or methods and in the steps or in the sequence of steps of the methods described herein without departing from the concept, spirit, and scope of the inventive concept(s). All such similar substitutions and modifications apparent to those skilled in the art are deemed to be within the spirit, scope, and concept of the inventive concept(s) as defined by the appended claims.
[0124] The use of the term "a" or "an" in the claims and/or the specification may mean "one," as well as "one or more," "at least one," and "one or more than one." As such, the terms "a," "an," and "the," as well as all singular terms, include plural referents unless the context clearly indicates otherwise. Likewise, plural terms shall include the singular unless otherwise required by context.
[0125] The use of the term "or" in the present disclosure (including the claims) is used to mean an inclusive "and/or" unless explicitly indicated to refer to alternatives only or unless the alternatives are mutually exclusive. For example, a condition "A or B" is satisfied by any of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
[0126] As used in this specification and claim(s), the words "comprising", "having", "including," or "containing" (and any forms thereof, such as "comprise" and "comprises," "have" and "has," "includes" and "include," or "contains" and "contain," respectively) are inclusive or open-ended and do not exclude additional, unrecited elements or method steps.
[0127] As used herein, a "smokeless article for oral delivery" is an article that does not need to be heated or burned in order to function. The smokeless article is for oral delivery, as used herein, the term "oral delivery" is intended to refer to any oral administration route achieved by placing the smokeless article into the oral cavity (mouth).

[0131] As used herein, the term "particle size" may indicate the average (mean) of the longest dimension of the fibres. For example, a particle size of 50 µm indicates that in the population of fibres, the maximum fibre length is, on average, 50 µm.
[0132] As used herein, the term "flavourant" denotes a compound having a desirable taste, aroma or both.
[0133] Unless otherwise explicitly stated as incompatible, or the physics or otherwise of the embodiments, examples, or claims prevent such a combination, the features of examples disclosed herein, and of the claims, may be integrated together in any suitable arrangement, especially ones where there is a beneficial effect in doing so. This is not limited to only any specified benefit, and instead may arise from an "ex post facto" benefit. This is to say that the combination of features is not limited by the described forms, particularly the form (e.g. numbering) of example(s), embodiment(s), or dependency of claim(s). Moreover, this also applies to the phrase "in one embodiment," "according to an embodiment," and the like, which are merely a stylistic form of wording and are not to be construed as limiting the following features to a separate embodiment to all other instances of the same or similar wording. This is to say, a reference to 'an,' 'one,' or 'some' embodiment(s) may be a reference to any one or more, and/or all embodiments, or combination(s) thereof, disclosed. Also, similarly, the reference to "the" embodiment may not be limited to the immediately preceding embodiment. Further, all references to one or more embodiments or examples are to be construed as non-limiting to the claims.
[0134] As shown in Fig. 1 there is provided a first embodiment of a smokeless article 10 having a pouch 12 containing a content 14. The pouch 12 is substantially rectangular. The pouch 12 is formed from a single sheet of material and is substantially filled by the content 14. The pouch 12 has a seal 16 along each of the three edges where the inner face of the single sheet meets itself to seal the content 14 in the pouch 12.
[0135] Fig. 2 shows a second embodiment of a smokeless article 10' having a pouch 12 containing a content 14. The pouch 12 is substantially circular. The pouch 12 is formed from two opposing sheets of material and is substantially filled by the content 14. The pouch has a circumferential seal 16 along the edges where the two opposing sheets of material meet to seal the content 14 in the pouch 12.
[0136] Fig. 3 shows a third embodiment of a smokeless article 10" that, like the first embodiment, has a pouch 12 made from a single sheet of material. However, one of the three seals 16' is formed by an overlap of the inner face and the outer face of the single sheet meet to seal the content 14 in the pouch 12. The remaining two seals at opposing ends of the pouch 12 are formed where the inner face of the single sheet meets itself.
[0137] Figure 4 shows a fourth embodiment of a smokeless article 10‴ that comprises the second embodiment enclosed by outer pouch 12" having an outer content 14" positioned in the space between the inner pouch 12' and the outer pouch 12". The outer pouch 12" also has a circumferential seal 16‴ to seal the outer content 14" and inner pouch 12' in the outer pouch 12".
[0138] Use of the fourth embodiment begins when the smokeless article 10‴ is placed in the user's mouth where it is exposed to saliva. Saliva first permeates outer pouch 12" and dissolves and extracts the saliva soluble substances of outer content 14". Upon leaving the outer pouch 12", the saliva soluble substances of outer content 14" therefore provide the user with a first experience. Saliva subsequently further permeates the inner pouch 12' where it dissolves and extracts the saliva soluble substances of inner content 14'. The saliva soluble substances of inner content 14' therefore provide the user with a complimentary and secondary experience. When the extractable amount of saliva soluble substances in the inner content 14' and outer content 14" drops below perceivable levels the active lifetime of the smokeless article 10‴ has ended.
EXAMPLES
Preparation of contents
[0139] The example contents were prepared according to the following method at the lab scale using a food processor.
- 1. All materials were dispensed into appropriately sized beakers using a 2 d.p. balance to determine weights.
- 2. Cellulosic material (coffee grinds), salt, sweeteners, and pH regulator are added to the food processor and mixed at full speed for 5 minutes.
- 3. Whilst mixing, the nicotine in water and flavourant is added over the course of 2-3 minutes.
- 4. The blend is mixed for a further 5 minutes, resulting in a final OND content.
[0140] The smokeless articles are then prepared by the following subsequent steps, making use of the content prepared as described above.
5. The content is filled into open or partially unformed pouches.
6. The open or partially unformed pouches are sealed and sprayed with water "water (sprayed)".
[0141] In this way, the following OND content (OND content 1) was prepared and inserted into pouches to form smokeless articles. Further OND contents were prepared by substituting the coffee grinds for the same w/w% amount (i.e., about 51.08 w/w%) of either lapsang tea leaves (OND content 2), vanilla rooibos tea (OND content 3), dulse seaweed (OND content 4), MARA seaweed dulse (OND content 5), MARA seaweed Kombu (OND content 6), corn silk (OND content 7), cocoa nibs (OND content 8), star anise (OND content 9), carob powder (OND content 10), and lapsang tea leaves and coffee grinds (OND content 11),which were each formed into smokeless articles.
[0142] Figure 5 shows a photograph of a container containing a plurality of snus pouches. Figure 6 shows a photograph of a container containing a plurality of smokeless articles filled with OND content 2. Figure 7 shows a photograph of a container containing a plurality of smokeless articles filled with OND content 4. Figure 8 shows a photograph of a container containing a plurality of smokeless articles filled with OND content 11.
[0143] The inventors performed qualitative experiments to compare the appearance, texture, odour and taste characteristics of each of OND contents 1-10 with a snus pouch. As shown below, the OND contents were scored in each of these sensory characteristic categories as either being a good match to a snus pouch (good), a medium match to a snus pouch (medium), or a poor match to a snus pouch (poor). Each of OND contents displayed at least one characteristic having at least a medium match to a snus pouch.
| OND Content | Appearance | Texture | Odour | Taste |
| 1 | Good | Good | Good | Good |
| 2 | Good | Good | Poor | Poor |
| 3 | Good | Good | Poor | Poor |
| 4 | Good | Medium | Poor | Poor |
| 5 | Good | Medium | Poor | Poor |
| 6 | Medium | Medium | Poor | Poor |
| 7 | Good | Good | Medium | Medium |
| 8 | Medium | Medium | Good | Good |
| 9 | Medium | Medium | Good | Good |
| 10 | Medium | Medium | Good | Good |
