Definitions

  • the present disclosure relates to a smokeless article.
  • the disclosure relates to a smokeless article for oral consumption comprising a pouch enclosing a content, the content comprising nicotine-dosed non-tobacco plant material fibres, wherein the plant material fibres have a particle size of up to 30 ⁇ m.
  • 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 nicotine-dosed non-tobacco plant material fibres, wherein the plant material fibres have a particle size of up to 30 ⁇ m.
  • the use of plant material fibres having a particle size of up to 30 ⁇ m provides a more material-efficient product with a smaller amount of material used to manufacture each article. This is due to the higher bulk density of the smaller 30 ⁇ m plant fibres compared with existing products, which enables the same level of nicotine to be provided within a pouch of smaller size containing a smaller volume of plant fibres.
  • the smokeless article of the invention is therefore more economical to manufacture and more environmentally friendly in that the amount of pouch material necessary per article is reduced and less material is wasted when the article is disposed of.
  • the nicotine-dosed non-tobacco plant material fibres comprise or consist of wheat fibres.
  • wheat fibres provide additional advantages.
  • a smokeless article comprising wheat fibres having a particle size of up to 30 ⁇ m provides an unexpectedly high nicotine release rate from the article.
  • a higher nicotine release rate provides a more effective product which is more desirable to some consumers.
  • the wheat fibres provide the product with a paler appearance which increases the eye appeal of the product to consumers.
  • the plant material fibres have a particle size of up to 30 ⁇ m. In some embodiments, the plant material fibres have a particle size of up to 29 ⁇ m, for example up to 28 ⁇ m, for example up to 27 ⁇ m, for example up to 26 ⁇ m, for example up to 25 ⁇ m or up to 20 ⁇ m.
  • the plant material fibres have a particle size of from 1 to 30 ⁇ m, for example from 2 to 30 ⁇ m, for example from 5 to 30 ⁇ m, for example from 10 to 30 ⁇ m, for example from 15 to 30 ⁇ m, for example from 20 to 30 ⁇ m, for example from 1 to 25 ⁇ m, for example from 2 to 25 ⁇ m, for example from 5 to 25 ⁇ m, for example from 10 to 25 ⁇ m, for example from 15 to 25 ⁇ m.
  • the plant material fibres have a particle size of about 30 ⁇ m.
  • the nicotine-dosed plant material fibres comprise a nicotinic compound selected from nicotine, nicotine salt(s), nicotine complex(es); and nicotine solvate(s).
  • the nicotinic compound is provided in a plant material.
  • the plant material is tobacco.
  • the smokeless article is tobacco-free.
  • the user may experience a similar or enhanced recreational/pharmaceutical effect as compared to conventional tobacco-containing products without experiencing undesirable components inherent to tobacco (e.g. tobacco flavour).
  • tobacco flavour undesirable components inherent to tobacco
  • the total nicotine content is from 5 to 15 mg, preferably about 10 mg.
  • greater than 75 wt%, preferably greater than 80 wt%, of the total nicotine content of the smokeless article is released from the smokeless article after 20 minutes immersed in water.
  • Another aspect of the invention is the use of nicotine-dosed non-tobacco plant material fibres, wherein the plant material fibres have a particle size of up to 30 ⁇ m, to increase the material efficiency of a smokeless article and/or reduce manufacturing cost.
  • the smokeless article is according to the first aspect.
  • Another aspect of the invention is the use of nicotine-dosed wheat fibres, wherein the wheat fibres have a particle size of up to 30 ⁇ m, as a nicotine release accelerant in a smokeless article for oral consumption.
  • the smokeless article is according to the first aspect.
  • particle size when referring to fibres such as wheat fibres indicates the maximum size of the longest dimension of the fibres. For example, a particle size of 50 ⁇ m indicates that in the population of fibres, the maximum fibre length is 50 ⁇ m.
  • 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 ⁇ m (i.e. a maximum fibre length of 300 ⁇ m), a population of fibres are passed through a sieve with 300 ⁇ m diameter apertures in the mesh. In this way, fibres with a length of 300 ⁇ m or less pass through the mesh and fibres longer than 300 ⁇ m 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 ⁇ m. Fibres of a desired particle size are also available from commercial suppliers such as Jelu-technik.
  • the term "wheat fibres” refers to natural fibres from plants of the Triticum genus of grasses, for example T. aestivum (common wheat).
  • the fibres may originate from any part of the plant, but in some embodiments may be originate from the stem of the plant.
  • the fibres may be obtained from commercial sources such as JELUCEL® WF fibres sold by Jelu-technik, or may be prepared by grinding or milling plant material until fibers of the required particle size are obtained.
  • the term "nicotine-dosed wheat fibres” refers to a composition comprising wheat fibres and a nicotinic compound.
  • the nicotinic compound may be added to or mixed with the wheat fibres prior to incorporation into the smokeless article.
  • the wheat fibres are loaded into a suitable dryer, sprayed with a solution of nicotinic compound and dried to form nicotine-dosed wheat fibres.
  • the dryer may be a fluidised bed dryer.
  • the solution may be a solution of nicotinic compound in glycerin.
  • the solution of nicotinic compound in glycerin may comprise from 10 to 50 wt% nicotinic compound based on the total solution weight, for example from 10 to 40 wt% or from 10 to 30 wt%.
