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 particulate material, the filling material being enclosed by the liquid permeable cover material.
  • 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 particles of microcrystalline cellulose or fiber material derived from plants other than tobacco.
  • 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.
  • the tobacco free oral pouched products are generally relatively dry products, with a pre-use 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 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.
  • oral pouched products having a relatively dry filling material made up mainly of a powdery or particulate material may be perceived by users as giving a disagreeably dry and gritty mouth feeling especially in an initial phase of use of such products.
  • Such products may also be found by users to have a less malleable consistency than desired.
  • An objective with the disclosure herein is to offer an oral pouched product containing a filling material having improved properties, in particular regarding mouthfeel and malleability.
  • the pouched product for oral use as disclosed herein comprises a liquid permeable cover material and a portion sized amount of a filling material comprising a particulate material, the filling material being enclosed by the liquid permeable cover material.
  • the particles of the particulate material have an average particle size within the range of from 0.3 mm to 3.0 mm, a particle density in the range of from 0.8 g/cm 3 to 1.7 g/cm 3 and a pre-use moisture content of from 1% by weight of the filling material to 35% by weight of the filling material.
  • a filling material for oral pouched products having a relatively low moisture content has been found to meet user expectations by providing a pleasant mouthfeel and good malleability when the filling material comprises a particulate material having relatively large particles and a relatively high particle density.
  • the particle size and the particle density of the particulate material combine to provide the material with a low dynamic coefficient of friction as measured according to the method disclosed herein and have been found to characterize a filling material having a high fluidity.
  • a high fluidity implies that the particles of the particulate material in the filling material can easily shift in relation to each other and to the cover material, resulting in the oral pouched products as disclosed herein having an excellent malleability and a fluid mouthfeel.
  • the filling material in the oral pouched products as disclosed herein may have a pre-use moisture content as determined by the method disclosed herein of from 1% by weight of the filling material to 30% by weight of the filling material, such as from 1% by weight of the filling material to 25% by weight of the filling material, such as from 1% by weight of the filling material to 15% by weight of the filling material, such as from 1% by weight of the filling material to 7% by weight of the filling material, such as from 5% by weight of the filling material to 30% by weight of the filling material, such as from 5% by weight of the filling material to 25% by weight of the filling material, such as from 5% by weight of the filling material to 15% by weight of the filling material, such as from 10% by weight of the filling material to 20% by weight of the filling material, such as from 10% by weight of the filling material to 15% by weight of the filling material.
  • a filling material in an oral pouched product as disclosed herein and having a relatively low pre-use moisture content 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.
  • the moisture content of the filling material in the oral pouched products as disclosed herein is less than 20% by weight.
  • the malleability of the oral pouched products as disclosed herein may be further enhanced by selecting a particulate material having a low content of small particles and fines.
  • a high content of small particles and fines may detract from the malleability of the filling material by lowering the ability of the particles in the particulate material to move freely in relation to each other. It may be preferred that the particulate material in the filling material as disclosed herein contains less than 0.5% of particles which are small enough to pass through a sieve having a mesh size of 250 ⁇ m.
  • a mesh size of 250 ⁇ m corresponds to a particle size in the order of a small to medium-sized 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 from a health and hygiene perspective of the manufacturing process.
  • the particles of the particulate material may have any useful shape, with regular shapes being preferred over irregular shapes. Furthermore, it may be preferred to use particles having a cylindrical or substantially cylindrical shape, a spherical or substantially spherical shape, or particles having an elongated rounded or substantially rounded shape such as an egg-shape or a grain shape.
  • a particle having a shape being substantially cylindrical, spherical, etc. implies that the overall shape of the particle may be e.g., spherical but that there may be irregularities in the particle surface such as dimples. Irregularly shaped particles having protruding parts, sharp corners and edges are generally less preferred.
  • the water insoluble particles may be relatively dense, non-porous particles having a particle density in the range of from 0.8 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 .
  • Dense, non-porous particles have a generally less irregular surface on a micro-scale which may contribute to further lower frictional forces between the particles as well as between the particles and the cover material.
  • the particles of the particulate material in the filling material as disclosed herein are relatively large particles and may have an average particle size within the range of from 0.4 mm to 3.0 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.
  • the particles of the particulate material in the filling material may have a sphericity within the range of from 0.7 to 1.0, such as from 0.8 to 1.0.
  • 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. The particles are separated from each other by a transportation fluid and overlapping particles are avoided. A high number of particles per image frame may be captured.
  • the particulate material in the filling material may comprise or consist of 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 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 water permeable outer cover material of the oral pouched products as disclosed herein may have an air permeability of from 4,500 I/m 2 /s to 10,000 I/m 2 /s, when measured according to the test method WSP070.1.R3(12) specified by EDANA, i.e. the European Disposables and Nonwovens Association.
  • the air permeability is associated with the porosity of the packaging material and hence also associated with its tendency to leak filling material.
  • a cover material having an air permeability of more than 4,500 I/m 2 /s is referred to herein as having a high air permeability.
  • the water permeable outer cover material may have a basis weight in the range of from 10 g/m 2 to 30 g/m 2 .
  • a cover material having a relatively low basis weight has a high air permeability and constitutes a minimal barrier to saliva transport into and out of the filling material in the oral pouched product.
  • Such cover materials have also been found to offer sensory benefits, in particular when combined with particles having a relatively large particle size, as disclosed herein. Larger which are small enough to pass through are freely movable inside the cover and which may be felt through a cover material may contribute to the particulate filling material in the oral pouched product being perceived as having a pleasantly fluid quality.
  • the particles of the particulate material in the filling material of the oral pouched products as disclosed herein may have a relatively large particle size in the range of from 0.3 mm to 3 mm, preferably from 0.5 mm to 3.0 mm, more preferred from 0.6 mm to 3.0 mm, and most preferred from 0.7 mm to 3 mm, in combination with a water permeable cover material having a relatively high porosity in the range of from 4,500 l/m 2 /s to 10,000 l/m 2 /s, when measured according to the EDANA test method WSP070.1.R3(12).
  • Highly permeable cover materials may be preferred as they allow saliva to readily pass into and out of the filling material and may contribute to a high release rate for active components, flavours, sweeteners etc. from the filling material enclosed by the cover material.
  • a drawback with highly porous cover material may be that there is a risk that also non-soluble substrate materials such as water insoluble particles and powder as well as fibres in the filling material may escape through the pores in the cover material and into the oral cavity of a user of the oral pouched product. By selecting large particles in combination with highly porous cover materials, the risk of escaping particles may be considerably reduced or even eliminated.
  • the liquid permeable cover material of the oral pouched product may be a nonwoven material.
  • the filling material of the oral pouched product as disclosed herein may comprise nicotine.
  • the nicotine may be derived from a nicotine source being a nicotine base and/or being 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 may comprise tobacco material in an amount within the range of from 0.05 wt% to 10 wt%, based on the total weight of said 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 sourced disclosed herein.
  • the filling material of the oral pouched product as disclosed herein may comprise an additive selected from the group consisting of a flavouring agent, a sweetener, a humectant, and any mixture thereof.
  • the additive may comprise or consists of a flavouring agent, such as a flavour oil, such as a hydrophobic flavour oil, such as a synthetic flavour, such as a nature-identical flavour.
  • a flavouring agent such as a flavour oil, such as a hydrophobic flavour oil, such as a synthetic flavour, such as a nature-identical flavour.
  • the filling material of the oral pouched product as disclosed herein may be free from tobacco material.
  • a tobacco free filling material may contain material derived from other plant sources such as coffee, tea, herbs, etc., and/or any suitable flavouring agent, sweetener, etc., as known in the art.
  • one or more water soluble component of the filling material may be present on an outer surface of at least some of the particles of the particulate material in the filling material, such as on 20% to 100% of the particles, or 50% to 100% of the particles, or 80% to 100% of the particles.
  • one or more water soluble component of the filling material may be present in interstices between the particles of the particulate material in the filling material.
  • One or more water soluble components may be present both on an outer surface of at least some of the particles in the filling material and in interstices between the particles in the filling material.
  • no or substantially no water soluble component of the filling material such as nicotine, flavouring agents, sweeteners, etc., is present in an internal pore structure in the particles of the particulate material of the filling material.
  • the filling material of the oral pouched product as disclosed herein may comprise more than one type of particles.
  • a first type of particles may be water insoluble particles and a second type of particles may be water insoluble particles or fully or partially water soluble particles.
  • oral and oral use refer to a use of a product in contact with mucous membranes in the oral cavity of a human being, such as buccal placement of the product in the oral cavity.

  • a major part of the water soluble components 11 i.e. components which are soluble in water and saliva, may to a large extent be present in the filling material 3 on surfaces of the particles 4 which are facing interstices 12 between the particles 4.
  • any water soluble components 12 may be substantially “concealed” within the mass of the filling material 3 where they do not add or do not substantially add to the volume of the filling material 3.
  • Fig. 3 shows only a very small number of particles 4.
  • the number of particles 4 in the particulate material is considerably higher, such as in the order of 150 particles or more which means that a large majority of the particle surfaces will be facing into the filling material 3.
  • the particles 4 of the particulate material may be dense, non-porous particles having a particle density in the range of from 0.8 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 .
  • dense non-porous particles no, or substantially no water soluble components 11 are present within the particles 4 themselves.
  • Figs. 4a , 4b , 4c and 4d illustrate some alternative shapes for the particles 4 of the filling materials 3 as disclosed herein.
  • the particles 4 which are shown in Fig. 4a have a substantially cubic shape
  • the particles 4 which are shown in Fig. 4b are grain-shaped
  • the particles 4 which are shown in Fig. 4c have a substantially cylindrical shape
  • the particles 4 which are shown in Fig. 4d have an irregular shape.
  • the particles 4 in Fig. 4a has an aspect ratio w/l which is approximately 1, while the particles 4 shown in Figs. 4b-4d have a smaller aspect ratio.
  • particle shapes having circular or oval cross-sections such as those shown in Figs. 3 , 4b, and 4c may be particularly preferred.
  • Irregular smoothly curved shapes such as shown in Fig. 4d are generally preferred over irregular shapes having sharp protrusions.
  • the moisture content as referred to herein may be determined by using a method based on literature references Federal Register/ vol.74, no. 4/712-719/Wednesday, January 7, 2009/Notices "Total moisture determination " and AOAC (Association of Official Analytical Chemics), Official Methods of Analysis 966.02: “Moisture in Tobacco” (1990), Fifth Edition, K. Helrich (ed ).
  • the moisture content is determined gravimetrically by taking 2.5 ⁇ 0.25 g sample and weighing the sample at ambient conditions, herein defined as being at a temperature of 22°C and a relative humidity of 60%, before evaporation of moisture and after completion of dehydration.
  • Mettler Toledo's Moisture Analyzer HB43 a balance with halogen heating technology, is used (instead of an oven and a balance as in the mentioned literature references) in the experiments described herein.
  • the sample is heated to 105°C (instead of 99.5 ⁇ 0.5°C as in the mentioned literature references).
  • the measurement is stopped when the weight change is less than 1 mg during a 90 seconds time frame.
  • the moisture content as weight percent of the sample is then calculated automatically by the Moisture Analyzer HB43.
  • the tests were carried out by applying a sample cover material on a test area of the horizontal test plate of the test apparatus having an extension of 215x130 mm.
  • a sample of 40 g of the filling material to be tested was applied on the cover material and was distributed evenly in the test area.
  • a three-walled enclosure of plastic bars was used to prevent spilling over of the filling material at the sides and rear of the test plate, while allowing motion of the test sled in the motion direction of the tow line.
  • the same cover material as the cover material on the horizontal plate of the test apparatus was applied to the friction sled and the sled was slid across the filling material yielding the dynamic coefficient of friction.
  • the tested filling materials were:
  • Example 1 was a filling material constituted by approximately 78% by weight of the total weight of the filling material of particles of microcrystalline cellulose having an average particle size of 945 ⁇ m, a particle density of 1.3 g/cm 3 and a bulk density of 0.78 g/cm 3 , and approximately 9% by weight of additional components based on the total weight of the filling material.
  • the moisture content in the filling material was 13% by weight of the filling material.
  • the cover material used in all three tests was a viscose nonwoven web comprising 40 wt% binder. 100% of the fibres in the cover material were viscose fibres having a linear density of 1.7 decitex and a basis weight of 29 g/m 2 .
  • Example 1 material according to the invention had a considerably lower coefficient of friction than the prior art filling material when measured against the same cover material.
