Definitions

  • the present invention relates to an oral pouched product, such as an oral pouched smokeless tobacco product, comprising a filling material, such as tobacco material, and a saliva-permeable pouch enclosing the filling material.
  • Smokeless tobacco for oral use includes chewing tobacco, dry snuff and moist (wet) snuff.
  • dry snuff has a moisture content of less than 10 wt % and moist snuff has a moisture content of above 40 wt %.
  • Semi-dry products having between 10% to 40 wt % moisture content are also available.
  • Smokeless tobacco products for oral use are made from tobacco leaves, such as lamina and stem of the tobacco leaf.
  • the material from roots and stalks are normally not utilized for production of smokeless tobacco compositions for oral use.
  • Both the American-type and the Scandinavian-type of moist snuff for oral use are available in loose form or portion-packed in a saliva-permeable, porous wrapper material forming a pouch.
  • Pouched moist snuff including snus, is typically used by the user by placing the pouch between the upper or lower gum and the lip or cheek and retaining it there for a limited period of time.
  • the pouch material holds the tobacco in place while allowing saliva to pass into the interior of the pouched product and allowing flavours and nicotine to diffuse from the tobacco material into the user's mouth.
  • the pouch material is typically made of a nonwoven fleece (soft fabric) material, such as viscose (regenerated cellulose; viscose fibres are often referred to as viscose rayon or rayon), including an acrylic polymer that acts as binder in the nonwoven material and provides for heat-sealing of the pouches during manufacturing thereof.
  • a nonwoven fleece (soft fabric) material such as viscose (regenerated cellulose; viscose fibres are often referred to as viscose rayon or rayon), including an acrylic polymer that acts as binder in the nonwoven material and provides for heat-sealing of the pouches during manufacturing thereof.
  • the viscose nonwoven material normally used for pouched smokeless tobacco products is similar to the fabric used in tea bags. Nonwovens are fabrics that are neither woven nor knitted. Methods for the manufacturing of nonwoven materials are commonly known in the art.
  • Pouched smokeless tobacco products may be produced by measuring portions of the smokeless tobacco composition and inserting the portions into a nonwoven tube.
  • U.S. Pat. No. 4,703,765 discloses a device for packaging precise amounts of finely divided tobacco products, such as snuff tobacco or the like, in a tubular packaging material into which snuff portions are injected via a fill tube. Downstream from the tube, welding means are positioned for transverse sealing of the packaging material, and also cutting means for severing the packaging material in the area of the transverse seal to thus form discrete or individual portion packages.
  • EP 2428450 B1 relates to a snus dosing method, wherein a portion of tobacco is filled into a dosing chamber of a dosing device and then blown out of the dosing chamber by means of blow-out air to which water vapor has been added.
  • Pouched smokeless tobacco products may alternatively be produced by placing portions of moist snuff on a nonwoven web using a pouch packer machine in accordance with the device disclosed in U.S. Pat. No. 6,135,120.
  • This device comprises feeding means for feeding the tobacco material into pockets formed in a rotary portioning wheel for portioning the material into portions, at least one compression means for compressing the tobacco material portions, a unit for advancing a packaging material, such as a nonwoven web, in synchrony with the compressed portions, at least one discharge means for discharging the portions from the pockets to the packaging material, and a forming unit for forming individual portion packages (i.e. pouched smokeless tobacco products) from the discharged portions and the packaging material.
  • said packaging material has the form of a tape, the compression means being arranged to compress the portions in a direction which differs from the discharging and the feeding directions.
  • the compression is preferably effected in a direction perpendicular to the discharging and the feeding directions.
  • the compression may be effected in the axial direction of the portioning wheel whereas the feeding and discharging may be effected in the radial direction of said wheel.
  • This technique is herein referred to as the “NYPS” technique.
  • each final pouched product includes parallel transverse seams with seals at opposite ends and a longitudinal seam with a seal orthogonal to the transverse seams/seals.
  • the seals should be of sufficient strength to preserve the integrity of the pouched product during use while not disturbing the user's experience.
  • the organoleptic properties, such as texture, aroma, taste, shape and appearance, of the pouched smokeless tobacco product are of high importance to the user.
  • Oral pouched smokeless tobacco products are normally sized and configured to fit comfortably and discreetly in a user's mouth between the upper or lower gum and the lip.
  • oral pouched smokeless tobacco products have a generally rectangular shape.
  • Some typical shapes (length x width) of commercially available oral pouched smokeless tobacco products are, for instance, 35 mm ⁇ 20 mm, 34/35 mm ⁇ 14 mm, 33/34 mm ⁇ 18 mm, and 27/28 mm ⁇ 14 mm.
  • the thickness (“height”) of the pouched product is normally within the range of from 5 to 7 mm.
  • the total weight of commercially available oral pouched smokeless tobacco products are typically within the range from about 0.3 to about 3.5 g, such as from about 0.5 to 1.7 g, per pouched product.
  • FIGS. 5 and 6 Examples of some present commercially available oral pouched snus products are shown in FIGS. 5 and 6 .
  • the oral pouched smokeless tobacco product may be visible, for instance, when the user smiles. Some users find this problematic and undesirable.
  • saliva passes into the interior of the pouched product and allows flavours and nicotine to diffuse from the tobacco material into the user's mouth.
  • the user's experience may be affected by the initial moisture content of the pouched product when put in the user's mouth and the saliva uptake (rate of uptake and amount of saliva taken up) by the pouched product.
  • Oral pouched smokeless tobacco products may be post-moisturized after pouch formation or not post-moisturized after pouch formation which herein is referred to as non-post-moisturized.
  • Post-moisturized pouched products may be produced by spraying water on the pouched smokeless tobacco product before packaging the pouched products in cans.
  • Post-moisturized pouches are sometimes referred to as “original snus”.
  • Non-post-moisturized pouched products are sometimes referred to as “white snus” and are by some users considered to have a more appealing appearance.
  • the moisture content of the final oral pouched smokeless tobacco product comprising moist or semi-dry snuff is normally within the range of from 25 to 55% w/w based on the weight of the pouched product (i.e. the total weight of snuff and pouch material).
  • Saliva is secreted by major and minor salivary glands located in the oral cavity.
  • the major salivary glands are the parotid glands, the submandibular glands and the sublingual glands.
  • the oral pouched smokeless tobacco product has initial high moisture content and/or a large amount of saliva is taken up by the pouched product, the user may experience that the pouched product becomes too runny (flowing) even though the taste may be satisfactory. Thus, the user may experience an unpleasant excessive amount of saliva/water in the mouth when the pouched product has been used by the user a period of time, such as after about 15-40 minutes.
  • An object of the present invention is to alleviate one or more of the problems discussed above, and to provide advantages and aspects not provided by hitherto known oral pouched products, in particular oral pouched smokeless tobacco products.

  • the longitudinal seam/seal of the pouch may be a symmetrically placed seam/seal or an asymmetrically placed seam/seal.
  • a lap seam/seal is formed by bringing an outer surface portion of the pouch material and an inner surface portion of the pouch material into a superposed relation.
  • a lap seal is illustrated in FIG. 2 a.
  • a fin seam/seal is formed by bringing inner surface portions of the pouch material into a superposed relation.
  • a fin seal is illustrated in FIG. 2 b.
  • a combined lap-and-fin seam/seal is formed by first bringing inner surface portions of the pouch material into a superposed relation, optionally sealing to form a fin seal, and then lap sealing the fin seam/seal to an outer surface portion of the pouch material.
  • a combined lap-and-fin seal is illustrated in FIG. 2 c.
  • inner surface of the pouch material refers to the surface of the pouch material that will form the interior of the final pouch, i.e. the side of the pouch material that will face the filling material enclosed in the pouch.
  • outer surface of the pouch material refers to the surface of the pouch material that will form the exterior of the final pouch.
  • FIGS. 2 a , 2 b and 2 c show seals held together by adhesive illustrated by the dashed regions. If any one of these seals instead is created by, for instance heat melt-welding or ultrasonic welding, portions of the pouch material will form a solid-state weld (i.e. no dashed region exists).
  • the transverse seams/seals of the pouch may be fin seams/seals.
  • Each of the transverse fin seals may correspond in width to the width of the respective transverse fin seam.
  • Fin seals may have a higher strength than lap seals.
  • the seals may be provided by any known suitable sealing method, such as by sewing, by applying an adhesive and/or by using a welding method selected from the groups consisting of heat melt-welding (heat and pressure), high frequency welding (high frequency electromagnetic waves and pressure) and ultrasonic welding (high frequency ultrasonic acoustic vibrations, such as about 15 kHz to 70 kHz, and pressure).
  • a welding method selected from the groups consisting of heat melt-welding (heat and pressure), high frequency welding (high frequency electromagnetic waves and pressure) and ultrasonic welding (high frequency ultrasonic acoustic vibrations, such as about 15 kHz to 70 kHz, and pressure).

  • the binder may be any suitable adhesive material, and suitable binders will be known to the skilled person.
  • suitable binders will be known to the skilled person.
  • thermoplastic binders based on polyacrylates can be used as suitable polymer binders.
  • Viscose nonwoven including an acrylic polymer is normally used for pouched smokeless tobacco products.
  • Heat melt-welding is commonly used today in the production of oral pouched smokeless tobacco products and this method may be used to create the transverse seal(s) and/or the longitudinal seal, if present, of the oral pouched product as disclosed herein.
  • Fin seals created by heat melt-welding may be within the range of from about 2 mm to about 5 mm in width. This means that fin seams comprising fin seals created by heat melt-welding may be within the range of from about 2 mm to about 5 mm in width.
  • Ultrasonic welding may be used to generate seals that are narrower in width (smaller) and more precise. Such seals are therefore tidier, more visually appealing and more discrete. They may also be more comfortable in the mouth of the user. Narrower seams/seals have the further advantage that the amount of pouch material required is reduced. Fin seals created by ultrasonic welding may be within the range of from about 0.1 mm to about 2 mm in width, such as within the range of from 0.1 mm to about 1 mm or 0.5 mm to about 1 mm in width. By using ultrasonic welding to create fin seals, the fin seams may be within the range of from about 0.5 mm to about 2 mm in width, such as from about 0.5 mm to 1 mm in width.

  • the typical main ingredients are water, sodium chloride (NaCl) and sodium carbonate (Na 2 CO 3 ).
  • Flavours and humectants e.g. propylene glycol or glycerol are also common ingredients and additional food approved additives might be used.
  • tobacco flour is produced by batch grinding. Compressed tobacco is emptied from its cases and torn to large fragments which are cut to pieces. The cut tobacco pieces are dried and transported to a mill. The tobacco is ground and ground tobacco particles are sieved and separated into fractions. Too large particles may be brought back to the mill for re-grinding. The cutting, grinding and sieving is done in equipment where foreign objects such as fragments of metallic material and stones are separated and removed from the tobacco. A number of approved fractions are weighed in separate fractions scales. The weighed tobacco flour fractions are collected to pre-set quantities in a container and blended by circulation. The blended tobacco flour is stored in a container. Different types of tobacco flours are kept in separate containers.
  • the snus mixture (herein referred to as smokeless tobacco composition) is produced by batch processing and should be carried out in a closed system to minimize the risk of contamination from bacteria or foreign substances. Since automatic feeding of tobacco and the other ingredients is preferred, the whole process may be computer controlled and can be run day and night, all week around.
  • the process normally starts with loading of tobacco material in powder form (tobacco flour), water, sodium chloride (NaCl) and possibly additional additives, into a cylindrical blender. Loading is done while stirring. The loaded materials are mixed to a homogeneous blend, which is heated by injection of steam. The blend is then kept heated for several hours with support of steam to ensure reduction of the natural bacterial flora in the tobacco and to bring texture, taste and color to the snus blend. Time, temperature and frequency of stirring during heat treatment, parameters specified for different snus blend qualities, are preferably controlled by a process computer program. After heat treatment, the blend is normally chilled by flow of cold water through the blender jacket during stirring. Water, flavours, pH adjuster, such as sodium carbonate, and possibly additional additives may then be added to the chilled blend. The blend is finally mixed to a homogeneous snus composition.
  • the oral pouched (i.e. portion-packed) products such as oral pouched smokeless tobacco products, as disclosed herein, may be positioned randomly in a container or in a pattern, as described in WO 2012/069505. Alternatively or additionally, each oral pouched (i.e. portion-packed) product may be placed in a sachet.

  • the target weight per pouched product is the total weight of the product (i.e. including filling material and pouch).
  • the moisture content of Table 1 is the average value of 3 to 4 measurements of about 3 ⁇ 0.5 g of the respective oral pouched smokeless tobacco products.
  • the maximum length and maximum width of the product were measured as illustrated in FIG. 1 a.
  • the approximate “thickness at waist” (generally referred to as the thickness of the product) was measured for each product as the height of the product, in a non-compressed state, at the centre of the maximum length of the product as illustrated in FIG. 1 b.
  • the centre of the maximum length of the product is herein referred to as the waist of the product.
  • the approximate “width at waist” was measured in a direction perpendicular to the direction in which “thickness at waist” was measured.
  • the transverse waist circumference (TWC) of the pouch was measured by cutting the product 1 around the waist of the product, such as along the two dotted lines shown in FIG. 3 a .
  • the thereby provided continuous annular piece of the pouch was cut open and the length of the resulting rectangular piece of pouch material was measured. This length is herein referred to as the transverse waist circumference of the pouch.
  • the longitudinal circumference (LC) of the pouch was measured by cutting the product 1 along the length of the product, such as along the two dotted lines shown in FIG. 3 b .
  • the thereby provided continuous annular piece of the pouch was cut open between the transverse seams and the length of the resulting rectangular piece of pouch material was measured. This length, which thus excludes the width of the two transverse seams 2 , is herein referred to as the longitudinal circumference of the pouch.
  • the LC-to-TWC ratio of the product according to Example 1 was about 3.0.
  • the thickness at waist and the width at waist of the product according to Example 1 was substantially the same; about 5 mm.
  • Each individual of a panel of 12 individuals were provided with 4 pouched snus products of Example 1, 4 pouched snus products of Ref. 1 and 4 pouched snus products of Ref. 2.
  • the format of Ref. 1 is, when sold commercially, referred to as “mini”.

  • FIG. 5 illustrates the maximum length (35 mm) and the maximum width (14 mm) of the commercially available pouched snus product “LaB 02” (Ref. 3a) having a product weight of 0.9 g.
  • FIG. 6 illustrates the maximum length (37 mm) and the maximum width (13 mm) of another commercially available pouched snus product called “Camel Frost” having a product weight 0.6 g.
  • Each individual of a panel 11 panelists the first day and 12 panelists the second day, was provided with two different types of pouched snus products in two replicates on two days in a row.
  • the reference product (called Ref. 4) was the commercially available product called “G.3 White XSTR PSWS” (Slim White Portion, 0.9 g, 1.8% nicotine, 46.5% water).
  • Example 2 Oral pouched snus products (called Example 2) having the same format as in Example 1 and containing the same snus composition as in the reference product were produced.
  • the panelists were instructed to put a snus product in the mouth under the upper lip and keep it there for 10 minutes, with a pause of a couple of minutes in between the two tested products.
  • the result of the test showed that even more individuals perceived the nicotine delivery as higher from the product of Example 1 despite the lower nicotine content of the product of Example 2 compared to the reference product. This result was unexpected since the amount of nicotine (9 mg) in the product of Example 2 was lower than the 10 amount of nicotine (16 mg) in the product of Ref. 4.
