Definitions

  • the present disclosure relates to a smokeless article.
  • the disclosure relates to a smokeless article comprising a pouch enclosing a content; the content comprising a non-tobacco filler material; wherein the non-tobacco filler material comprises: greater than 25 wt % of nicotine-dosed cellulose; and a nicotine-dosed non-tobacco plant material.
  • Smoking is generally considered to expose a smoker to potentially harmful substances. It is generally thought that the majority of the potentially harmful substances are formed by the heat generated during burning (combustion) of the article. There is interest in so-called heat not burn products, which heat a tobacco or similar substrate at a lower temperature than a conventional cigarette. These products are usually described as less harmful than conventional cigarettes. Both conventional cigarettes and heat not burn products are visible during use and produce smoke or vapour.
  • Smokeless articles are a suitable alternative because they do not require heating for substance delivery to the user. Instead, smokeless articles rely on saliva to extract soluble substances, typically nicotine and/or flavours, from tobacco contained within the smokeless article.
  • Conventional smokeless articles have a saliva permeable pouch housing a content.
  • the content is generally in the form of tobacco, said tobacco containing a soluble element, typically nicotine.
  • a product may be referred to as portion snus. It is typically provided as prepackaged (traditionally moist) powder in small teabag-like pouches. Each pouch is a single portion or unit. This moistened product may be referred to as original snus.
  • Smokeless articles are placed in the mouth where saliva extracts the soluble element from the tobacco contained within.
  • 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.
  • the resulting saliva which contains extracts, subsequently contacts a mucous membrane in the mouth, or at another point of the gastrointestinal tract, to deliver the soluble element across the membrane and into the bloodstream.
  • the soluble element is then transported by the bloodstream to the site of action. For example, nicotine is delivered to the brain where it acts upon acetylcholine receptors.
  • Snuff is smokeless tobacco made from ground or pulverised tobacco leaves. Snuff is available in dry form or wet (moist) form. Moist snuff may be referred to as snus. Two common varieties of snus are Scandinavian snus and American snus. Both varieties of snus are available in a loose form, but are often contained within a saliva permeable pouch.
  • snus is typically manufactured by grinding a blend of leaf tobaccos to specified particle sizes.
  • the ground tobacco is then mixed with water and sodium chloride in closed process blenders.
  • the mixture is subjected to a heat treatment, involving temperatures up to 80 - 100 °C, for several hours to pasteurize the snus. Thereafter, the snus is cooled and other ingredients may be added.
  • Snus is typically manufactured to meet the GothiaTek® standard, as detailed in " Swedish snus and the GothiaTek® standard” (2005), Rutqvist , et al.
  • the present disclosure relates to a smokeless article e.g. a snus article for oral use.
  • a smokeless article for oral consumption comprising a pouch enclosing a content; the content comprising a non-tobacco filler material; wherein the non-tobacco filler material comprises:
  • the smokeless article of the invention provides a reduced nicotine release rate. Due to the particular combination of greater than 25 wt% nicotine-dosed cellulose and nicotine-dosed non-tobacco plant material, nicotine is released from the smokeless article of the invention over a longer period of time relative to known smokeless articles containing the same total amount of nicotine. The consumer is therefore exposed to a lower level of nicotine when using the product, which may be desirable for e.g. first-time users or those who wish to maintain a lower level of nicotine exposure. This altered release profile offers a means to manufacture a more versatile product providing a tailored rate of nicotine release.
  • the reduced nicotine release rate also provides the benefit of extending the usable lifetime of the smokeless article, thereby enhancing the user experience of the product.
  • the nicotine-dosed cellulose comprises a cellulose component and a nicotine component.

  • a first embodiment of a smokeless article 10 having a pouch 12 containing contents 14.
  • the pouch 12 is substantially rectangular.
  • the pouch 12 is formed from a single sheet of material and is substantially filled by the contents 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 contents 14 in the pouch 12.
  • Figure 2 shows a second embodiment of a smokeless article 10' having a pouch 12 containing contents 14.
  • the pouch 12 is substantially circular.
  • the pouch 12 is formed from two opposing sheets of material and is substantially filled by the contents 14.
  • the pouch has a circumferential seal 16 along the edges where the two opposing sheets of material meet to seal the contents 14 in the pouch 12.
  • Figure 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 contents 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.
  • Figure 4 shows a fourth embodiment of a smokeless article 10'" that comprises the third embodiment enclosed by outer pouch 12" having an outer contents 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 contents 14" and inner pouch 12' in the outer pouch 12".
  • 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 contents 14". Upon leaving the outer pouch 12", the saliva soluble substances of outer contents 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 contents 14'. The saliva soluble substances of inner contents 14' therefore provide the user with a complimentary and secondary experience. When the extractable amount of saliva soluble substances in the inner contents 14' and outer contents 14" drops below perceivable levels the active lifetime of the smokeless article 10'" has ended.
  • Two smokeless articles according to the invention were prepared and tested: the first containing 50 wt% nicotine-dosed wheat and 50 wt% nicotine-dosed MCC (Article A), and the second containing 100 wt% nicotine-dosed MCC (Article B).
  • Each of Articles A-D contained the same total nicotine content (10 mg) and were tested for nicotine release rate under identical conditions.
  • the samples were tested by immersing each of the samples in the same model solution representing human saliva.
  • the model solution was made with deionised water containing the following ingredients: Ingredient Content (g/1000mL) Magnesium chloride hexahydrate 0.17 Potassium hydrogen phosphate anhydrous 0.68 Sodium chloride 0.33 Potassium chloride 0.75 Calcium chloride dehydrate 0.15 Potassium carbonate 0.53 Hydrochloric acid to pH 6.8 ⁇ 0.1
  • the model solution was prepared by mixing all ingredients in the table except hydrochloric acid and transferring to a 2 L glass reservoir. 500 mL of deionised water was added and the solution was mixed well to dissolve. Further deionised water was added to bring the total amount of deionised water added to 1 L. The reservoir was sealed and mixed well. The pH was then adjusted to 6.8 by the addition of HCI. The solution was used within 2 days of preparation.
  • Nicotine concentration in the model solution was determined at certain time intervals by an optimised HPLC method using USP 4 flow-through dissolution apparatus with online UV system, thereby providing an indication of the rate of release of nicotine from the immersed pouch.
  • Figure 5 shows the nicotine release rate from smokeless articles according to the invention and comparative smokeless articles over a 90 minute period.
  • the smokeless articles A and B according to the invention displayed a slower nicotine release rate over the period from 10-50 minutes of product use relative to the comparative articles C and D, which corresponds to the period of time for which the product would be used by a consumer before disposal. After 15 minutes, Articles A and B had each released approximately 4.5 mg of nicotine compared with 6 mg released from Articles C and D. After 50 minutes, Articles A and B had each released around 7-8 mg of nicotine compared with around 9-10 mg released from Articles C and D.
  • the invention provides a means to reduce the rate of nicotine release from a smokeless article such that nicotine is released more gradually over a longer period of time.
