Definitions

  • the present disclosure relates to a pouched product for oral use comprising a liquid permeable cover material and a portion sized amount of a filling material comprising a liquid insoluble particulate material, and one or more water-soluble components in addition to the particulate material, the filling material being enclosed by the liquid permeable cover material, the particles of the particulate material having a particle density and a bulk density.
  • An oral pouched product as disclosed herein is intended for use in the oral cavity, such as by buccal placement e.g., by placing the pouched product between the upper or lower gum and the lip or cheek.
  • a pouched smokeless tobacco product may also be referred to as a portion-packed smokeless tobacco product for oral use.
  • the pouched product is normally sized and configured to fit comfortably and discreetly in a user’s mouth between the upper or lower gum and the lip or cheek.
  • oral pouched products are used in the oral cavity of a consumer to provide a user with the benefits of an active substance such as nicotine, caffeine, and/or different flavors.
  • a common type of nicotine containing oral pouched products is oral smokeless tobacco products.
  • Such products generally comprise water, salt, pH adjuster(s) and additional components such as flavors and humectants. Commonly, these products are called snuff.
  • Oral pouched nicotine containing products comprising no tobacco, or only a small amount of tobacco, are now becoming increasingly popular among consumers due to inter alia their appealing appearance, freshness, and taste. Moreover, this kind of product allows a user to enjoy nicotine without being exposed to tobacco.
  • the tobacco free or almost tobacco free oral pouched products are usually flavored compositions comprising a filling material which may e.g., comprise microcrystalline cellulose or fiber material derived from plants other than tobacco. 2021-12-20 PG22105PC00 / P00196PCT
  • the tobacco free oral pouched products are generally relatively dry products, with a preuse moisture content below 35% by weight of the filling material and often below 20% by weight of the filling material. Oral pouched products having even lower moisture content, in the order of 4-10 % by weight of the filling material are also known in the art.
  • oral pouched products are those which only deliver a flavor into the oral cavity and those which are designed for delivering active substances other than nicotine.
  • Oral pouched products are typically used by a consumer by placing the pouch between the upper or lower gum and the lip and retaining it there for a limited period of time.
  • the product is configured to fit comfortably and discreetly in the user's mouth.
  • the pouch material holds the filling material in place allowing saliva to pass into the filling material and allowing flavors and active substances such as nicotine to diffuse from the filling material into the consumer's mouth.
  • An objective with the disclosure herein is to offer an oral pouched product containing a filling material having improved properties, such as mouthfeel, user satisfaction and rapid release of components, such as active agents and flavors.
  • the pouched product for oral use as disclosed herein comprises a liquid permeable cover material and a filling material comprising a particulate material consisting of water insoluble particles, and one or more water-soluble components in addition to the particulate material.
  • the filling material is enclosed by the liquid permeable cover material.
  • the particles of the particulate material have a particle density and a bulk density.
  • the particles of the particulate material have a particle density in the range of from 0.9 g/cm 3 to 2.0 g/cm 3 .
  • the particle density is at least 1.4 times greater than the bulk density of the particulate material.
  • the filling material has a pre-use moisture content of from 1% by weight of the filling material to 35% by weight of the filling material.
  • the filling material is 2021-12-20 PG22105PC00 / P00196PCT
  • the filling material comprises tobacco material in an amount within the range of from 0.05 wt% to 10 wt% based on the total weight of the filling material.
  • the particle density of the particulate material may be from 1 .4 to 5 times greater than the bulk density of the particulate material, such as from 1 .5 to 4 times greater than the bulk density of the particulate material.
  • the bulk density of the particulate material is 0.6 g/cm 3 or less, and with a particle density of 2 g/cm 3 , the bulk density of the particulate material is 1.4 g/cm 3 or less.
  • the difference in particle density and bulk density reflects the amount of void volume in the filling material which is created by the interstices between the water insoluble particles of the particulate material.
  • the difference in particle density and bulk density is low, the amount of void volume in the filling material is low.
  • the difference in particle density and bulk density is high, the amount of void volume will be high.
  • a large void volume allows a correspondingly large amount of saliva to be contained within the bulk of the filling material.
  • the interstices between the particles form a macro-scale network of channels within the filling material, in which channels saliva can flow into and out of the filling material.
  • the water-soluble components in the filling material can readily dissolve in the saliva and can be rapidly transported out of the filling material in the macro-scale channels formed by the interstices between the water insoluble particles, resulting in a rapid release of water-soluble components into the oral cavity of a user.
  • Mechanical working of the pouch during use may further aid in promoting saliva transport in the filling material and rapid release of water-soluble components by changing the configuration of the channel network, thereby creating a “pumping action” within the mass of the filling material.
  • the filling material in the oral pouched products as disclosed herein have a pre-use moisture content as determined by the method disclosed herein of from 1 % by weight of the filling material to 35% by weight of the filling material.
  • the filling material in the oral pouched products as disclosed herein may have a pre-use moisture content as 2021-12-20 PG22105PC00 / P00196PCT
  • the filling material such as from 1 % by weight of the filling material to
  • the moisture content of the filling material in the oral pouched products as disclosed herein is less than 20% by weight.
  • a filling material in an oral pouched product as disclosed herein and having a relatively low pre-use moisture content as set out above is perceived by users to be fresh and agreeable to handle when taking it out of a user container and tucking it in, e.g., between the upper or lower lip and the gum of the user.
  • a relatively low pre-use moisture content also allows the particles of the particulate material constituting the bulk volume of the filling material to move more freely in relation to each other, which makes the oral pouched product easier to shape and to be made to conform to the shape of the space where the oral pouched product is placed in the oral cavity of the user.
  • the particulate material in the filling material are water insoluble particles.
  • the water insoluble particles may be particles of microcrystalline cellulose, water insoluble starch, silica, or a mixture thereof.
  • the water insoluble particles of the particulate material are relatively dense, non-porous particles having a particle density in the range of from 0.9 g/cm 3 to 2.0 g/cm 3 , such as from 1.0 g/cm 3 to 1.7 g/cm 3 , such as from 1.0 g/cm 3 to 1.5 g/cm 3 , such as from 1.1 g/cm 3 to 1 .4 g/cm 3 . 2021-12-20 PG22105PC00 / P00196PCT
  • Using dense non-porous water insoluble particles may enhance rapid release of water- soluble components from the filling material as essentially no, or only a minor amount of water-soluble components will be present in pores within the water insoluble particles of the particulate material in the filling material.
  • the water insoluble particles of the particulate material may constitute 75% by dry weight to 99% by dry weight of the filling material, such as 85% by dry weight to 98% by dry weight of the filling material or 95% by dry weight to 98% by dry weight of the filling material.
  • the particles of the particulate material may constitute 85% by dry weight to 99% by dry weight of the filling material.
  • the volume of the water insoluble particulate material in the filling material preferably defines the volume of the filling material, with any additional component of the filling material of the oral pouched product contributing only to a negligible or very small extent to the volume of the filling material.
  • a very small extent is implied a contribution to the volume of the filling material by components other than the particles of the particulate material of less than 5%, such as of less than 3%, of less than 2%, preferably of less than 1%.
  • the oral pouched products of the present disclosure may have a volume after use which is in the same order as the volume before use of the oral pouched product. This means that the volume of the oral pouched product may remain largely unchanged during use of the oral pouched product, which is a property of the oral pouched product that has been found to be appreciated by many users. An oral pouched product which does not lose volume during use may be perceived as retaining the mouthfeel of a new fresh product and to be more malleable and satisfactory to keep in the mouth for a longer time of use.
  • the particles of the particulate material in the filling material are preferably relatively large particles and may have an average particle size within the range of from 0.3 mm to 3.0 mm, such as from 0.4 mm to 3.0 mm, such as from 0.3 mm to 2.5 mm, such as from 0.4 mm to 2.5 mm such as from 0.5 mm to 2.5 mm, such as from 0.6 mm to 2.5 mm, such as from 0.7 mm to 2 mm, such as from 0.8 mm to 1.5 mm, such as from 0.85 mm to 1.2 mm.
  • the particles of the particulate material in the filling material may be of generally the same size, with a narrow particle size distribution profile. 2021-12-20 PG22105PC00 / P00196PCT
  • the particles of the particulate material in the filling material are preferably spherical or generally spherical particles having a sphericity within the range of from 0.7 to 1.0, such as from 0.8 to 1.0 and a diameter of from 0.3 mm to 3 mm, such as from 0.4 mm to 3 mm such as from 0.7 mm to 3 mm.
  • Sphericity and particle size may be determined with the aid of a QicPic image analysis instrument from 2012, Sympatec GmbH, ID No. 290-D, with Rodos/L dispersion line ID NO 214D and Vibri/L sample feeding ID NO 273, or equivalent equipment.
  • a well dispersed particle flow is led through the image plane of the instrument. If the particles are small, a high number of particles per image frame may be captured, such as in the order of 50,000-100,000 particles per image frame. For larger particles, such as particles having a particle size from 300 pm to 3000pm, the number of particles per image frame may be substantially less and may be in the order of from 300 to 2000 particles per image frame.
  • the particulate material in the filling material as disclosed herein may contain less than 0.5% of particles which are small enough to pass through a sieve having a mesh size of 250 pm.
  • a mesh size of 250 pm corresponds to a particle size in the order of a small to mediumsized grain of sand. Such particles are extremely unpleasant if they escape out through the cover material into the oral cavity of a user as they give rise to a gritty and dry mouthfeel which may linger for a long time after the product has been placed in the oral cavity, especially if the particles are non-soluble particles.
  • Small particles and fines in a filling material may also cause problems with dusting during manufacturing of oral pouched products, as they may impair seal formation and may cause clogging of machine parts. It is also desirable to minimize the amount of dust in the manufacturing process from a health and hygiene perspective.
  • the filling material of the oral pouched product as disclosed herein may comprise nicotine. 2021-12-20 PG22105PC00 / P00196PCT
  • the large void volume between the particles of the particulate material contributes to provide the oral pouched product with a high release rate for nicotine and other active ingredients, flavours, sweeteners etc., which are present in the oral pouched product.
  • the nicotine may be added to the particulate material of the filling material in the form of a nicotine compound.
  • the nicotine compound may be a nicotine base and/or may be selected from the group consisting of nicotine hydrochloride, nicotine dihydrochloride, nicotine monotartrate, nicotine bitartrate, nicotine bitartrate dihydrate, nicotine sulphate, nicotine zinc chloride monohydrate and nicotine salicylate, nicotine benzoate, nicotine polacrilex and any combination thereof.
  • the filling material of the oral pouched product as disclosed herein is a tobacco free filling material or a filling material having a low tobacco content, the filling material comprising tobacco material in an amount within the range of from 0.05 wt% to 10 wt%, such as from 0.05 wt% to 1 wt% or from 0.2 wt% to 1 wt%, based on the total weight of the filling material.
  • the tobacco material may be a nicotine source.
  • the tobacco material may be the only nicotine source or may be a nicotine source in addition to one or more of the nicotine compounds disclosed herein.
