  • According to a preferred embodiment of the second aspect of the present invention, one or more sweeteners, pH adjusting agents, colours or flavours are added. [0039]
  • According to a preferred embodiment of the second aspect of the present invention the load layers are pressed repeatedly after folding, preferably more than 30 times, before the backbone layer is added to the load layers to form the multi-layered tobacco product. [0040]
  • According to a preferred embodiment of the second aspect of the present invention a lubricant is distributed on the load layers before each folding, preferably the load layers are sprinkled with cornstarch before each folding. The lubricant may be potato fluor, talc or cornstarch, preferably cornstarch. [0041]
  • According to a preferred embodiment of the second aspect of the present invention the tobacco product is coated with a coating layer or is patterned. A method of achieving a patterning effect on the tobacco product surface and therefore a further preferred embodiment of the invention, comprises continuously printing the tobacco product with a coating substance, leaving gaps on the tobacco product that may correspond to marks, logotypes, texts or anagrams, thereby for printing of the tobacco product. A coloring agent may further penetrate through the outer layer of the tobacco product at such open points and not on the remaining surface that would be protected by the coating substance. Printing may thus be based upon applying the coating substance as a printed background, leaving the foreground or printed characters without this coating substance, and hence when the tobacco product with the layers inside undergoes coloring operations, it will only be penetrated through areas without the coating substance, leaving the surface of such tobacco product marked by the areas without coating substance. [0042]
  • According to a preferred embodiment of the second aspect of the present invention the tobacco product is subsequently punched out in pieces for oral use, preferably essentially circular pieces. The pieces are further preferably in size for use in the mouth, most preferred under the upper lip of a human being. If the pieces are circular they may preferably have a diameter of approximately 7 mm. [0043]
  • According to a preferred embodiment of the second aspect of the present invention the out-punched tobacco product is put on a carrier, preferably a strip of cloth, most preferred a cloth comprising heat-sealable non-woven, and optionally subsequently the cloth is sealed, preferably using heat. [0044]
  • According to a preferred embodiment of the second aspect of the present invention a further carrier, preferably a strip of cloth, most preferred a cloth comprising heat-sealable non-woven, is added on the other opposite side of the out-punched tobacco product, thus forming a sandwich with the tobacco product in the middle, and optionally subsequently the two carriers are sealed together, preferably using heat. The sealing may create a quadratic seal around each tobacco product (composition). The pieces (i.e. the tobacco product) with a diameter of approximately 7 mm, may be put between two strips of heat-sealable non-woven with a width of approximately 12 mm and sealed. [0045]
  • According to a preferred embodiment of the second aspect of the present invention a tobacco product obtainable by a method according to the second aspect is provided. [0046]
  • According to a preferred embodiment of the first and second aspect of the invention a container comprising one or more tobacco products, wherein preferably said container is a can with a lid, is provided. [0047]
  • According to a preferred embodiment of the first and second aspect of the invention i.e. one or more tobacco products are presented in the form of a spool, coil or reel. [0048]
  • Generally described the present invention provides according to the first aspect of the invention a tobacco product stabilized with hydrophobic plasticizers and constructed of more than one layer. The layers function to increase the nicotine yield or keep the nicotine yield high, hold the construction and improve the appearance. The present invention is constructed to function without chewing. The construction (the tobacco composition) will essentially be destroyed and the product will break up in pieces if it is chewed. The preferred use is under the upper lip of a human being. The product is essentially not soluble, just nicotine and taste are extracted from the invention when used in the mouth. In a non-chewing product nicotine release depends on the amount of nicotine and on the size of the surface exposed to saliva. In the present invention steps are taken to expand the surface. The product (the tobacco composition according to the first aspect) is made of thin layers loosely kept together, permitting saliva to wet the layers from between. The layers may preferably contain little plasticizers to promote some cracking, allowing salivia to penetrate the structure. To improve the appearance, “the stay in place performance” or the initial taste the exterior layers may contain other mixture, components or material compared to the inner ones. For example less tobacco, which makes it easier to colour. Stay in place improvement may be coating, “pattern” as set out above or a non-woven outer layer. [0049]
  • Preferred features of each aspect of the invention are as for each of the other aspects mutatis mutandis. The prior art documents mentioned herein are incorporated to the fullest extent permitted by law. The invention is further described in the following examples, which do not limit the scope of the invention in any way. Embodiments of the present invention are described in more detail with the aid of examples of embodiments, the only purpose of which is to illustrate the invention and are in no way intended to limit its extent.[0050]
  • EXAMPLES Example 1
  • This is a product for use under the upper lip. It can be made in strips to let the consumer decide the size or in portion pieces with different shapes. [0051]
    25% titanium dioxide
    30% tobacco powder
  • To form the invention all dry ingredients were first mixed. If the addition of sweeteners, pH adjusting agents, colours, flavours and others were large it was necessary to reduce the amount of titanium oxide or tobacco powder to keep the plastic properties. [0052]
    11% glycerol
    4% water
  • All wet components were stirred in. [0053]
    25% chewing gum base (Smily 2 toco Pellets from Gum Base Company
    S.p.A., Italy)
  • The gum base was heated to about 70° C. before it was added. This mixture should be mixed to a smooth dough. Depending on the size of the batch, it might be necessary to heat the mixture. The dough was processed in a pasta machine (Atlas, manufactured by Marcato); rolled, sprinkled with cornstarch and folded. This was repeated for at least 30 times, to a thinner and thinner plate. The end thickness should be about 1 mm. This plate was the load layer. A backbone with a thickness less than 0,5 mm was made of gum base in a pasta machine. A backbone layer was put between two load layers and was rolled in the pasta machine to a product plate with a thickness of about 2 mm. [0054]
  • The pressure is critical by the use of the pasta machine—if it is to high it will damage or destroy the layers. [0055]
  • The product plate can be coated or patterned before the product is cut or punched out from it. [0056]
  • Example 2
  • This is punched pieces of the invention in a spool of non-woven. The product is easy to keep in place, it lets the customer decide dose and it has a clean look. [0057]
    53% tobacco powder
  • To form the invention all dry ingredients were first mixed. If the addition of sweeteners, pH adjusting agents, colours, flavours and others are large it may be necessary to reduce the amount of tobacco powder to keep the plastic properties. [0058]
    16% glycerol
    9% water
  • All wet components were stirred in. [0059]
    16% chewing gum base
  • The gum base was heated to about 70° C. before it is added. This mixture should be mixed to a smooth dough. The dough was processed in a pasta machine to make a thin plate. This dough is hard to get through the pasta machine, but no layers are needed. A plate with a thickness of 12-15 mm is sufficiently. This is the load layer. The exterior layers (cosmetic layers) were made according to the procedure in Example 1, but when a smooth dough was reached no layers were built up instead the dough was rolled to a very thin plate less then 0,5 mm thick. The load layer was put between two exterior layers and was rolled in the pasta machine to a product plate with a thickness of about 2 mm. [0060]
  • The product plate can be coated before the product is punched out in circular pieces about 7 mm in diameter. The pieces were put between two strips of heat-sealable non-woven with a width of 12 mm and sealed. [0061]
  • Various embodiments of the present invention have been described above but a person skilled in the art realizes further minor alterations, which would fall into the scope of the present invention. The breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents. For example, any of the above-noted methods and products can be combined with other known methods and products. Other aspects, advantages and modifications within the scope of the invention will be apparent to those skilled in the art to which the invention pertains. [0062]
