Definitions

  • the present invention is related to a tobacco product for an aerosol generating device, wherein the tobacco product comprises an aerosolizable agent and a shell, the aerosolizable agent being encapsulated by the shell, wherein the shell comprises a hydrocolloidal material, is fluid tight at an ambient storage temperature of the tobacco product and decomposable by heat.
  • Capsules with flavour for usage in conventional cigarettes are known in the tobacco industry. Such capsules often contain flavour compounds like menthol, fruit flavours or other synthetic flavours. And by releasing their flavoured content, the capsule provides an extra taste sensation to the user.
  • the document WO2019166640A1 for example discloses a breakable capsule which is arranged in an aerosol generating article for a heat not burn device.
  • the capsule comprises a liquid, which can be released from the capsule by applying force on the capsule and crushing it.
  • flavours Although there are many different types of flavours available on the market, some users prefer an intense and natural taste of tobacco. Since an intense flavour of tobacco is sometimes not possible by just heating tobacco in heat not burn devices, people who appreciate an intense flavour may not be satisfied with such devices. Until now, capsules with flavours have been built in such way that a consumer has to crush the capsule to release the flavour. This is especially disadvantageous if the capsule contains natural flavours and should preferably be broken just when the taste of the actual tobacco product is fading.
  • the aerosolizable agent in the tobacco product comprises tobacco particles and an aerosol former which are aerosolizable by heat.
  • a tobacco product according to the invention can be used in an aerosol generating device which is preferably an electronic powered smoking device.
  • the tobacco product can be used in combination with an aerosol generating article for generating an inhalable aerosol when heated.
  • the tobacco product is then preferably arranged inside a filter section of the aerosol generating article.
  • the filter section of the aerosol generating article is used as an aerosol outlet or mouthpiece of the aerosol generating system.
  • the shell of the tobacco product is decomposable by heat. Preferably, by applying heat to the tobacco product during smoking, the shell decomposes to a point it releases the aerosolizable agent into the aerosol generating article.
  • decomposable means that the shell is no longer fluid-tight when heated and thus no longer completely encloses the aerosolizable agent or releases it into the environment.
  • the term “decomposition” thereby describes a fusion and/or melting and/or softening until rupturing of the shell.
  • the tobacco product can also be used alone and thereby not in combination with any further aerosol generating article. It is conceivable that the tobacco product is then arranged in an aerosol generating device in such way, that it is heated by a heating element of the device. Preferably, by applying heat to the tobacco product during usage of the device, the shell of the tobacco product decomposes and releases the aerosolizable agent into device. Preferably the tobacco product aerosolises during heating and also preferably the resulting inhalable aerosol is released through a mouthpiece or filter section which functions as an aerosol outlet of the device.
  • the material of the shell is meltable at a minimum temperature of 50°C, more preferably at 60°C and most preferably at 70°C. Also preferably the material of the shell is meltable at a maximum temperature of 100°C, more preferably at 90°C and most preferably at 80°C.
  • the shell is thereby meltable within the following temperature ranges:
  • the shell has a maximum thickness of less than 100 microns, preferably between 1 and 40 microns and most preferably between 1 and 10 microns. It is conceivable that other thicknesses can also be used. Preferably other thicknesses are used by a changing of the ingredients or composition of the shell to preferably maintain the same or similar stability at ambient and decomposition under same or similar heat.
  • the shell of the tobacco product is thick enough to protect the aerosolizable agent from external influences. It is conceivable that such influences can be heat and/or force and/or light.
  • the shell at least partially dissolves at a certain temperature, releasing the enclosed aerosolizable agent.
  • the tobacco particles have a mean particle size (D90) equal to or less than 100 microns, preferably equal to or less than 50 microns and most preferably equal to or less than less than 30 microns. It is conceivable that the particles can also have a mean particle size (D90) of less than 100 microns, preferably less than 50 microns and most preferably less than 30 microns. It is conceivable that the particles can also have a mean particle size (D90) of less than 100 microns, preferably less than 50 microns and most preferably equal to or less than 30 microns. It is conceivable that the particles can have a greater and preferably also smaller particle size. It is also conceivable that smaller tobacco particles have a greater surface and thereby preferably release more taste. It is conceivable that the tobacco particles have a size at which mixing with an aerosol former results in a paste.
  • D90 mean particle size
  • each of the ingredients for the aerosol former can be used alone. Further it is conceivable that at least two of the ingredients can be combined. Preferably, also materials can be used which are mentioned in the groups of the above-mentioned ingredients. It is conceivable that the used material is aerosolizable by heat and produces preferably vapour upon heating. Further it is conceivable that the aerosol former comprises at least one of the mentioned ingredients and is preferably mixed with tobacco particles to form the aerosolizable agent.

Preferably the mixture of the aerosol former and the tobacco particles forms the aerosolizable agent.
  • the aerosolizable agent may further comprise at least one flavour for altering the natural tobacco taste and providing different taste experiences to the customer.
  • Flavours can be obtained by extraction from natural source or by chemical synthesis.
  • sources of flavours includes menthol, mint, coffee, tea, cinnamon, ginger, lemon, water melon, berry, thyme, etc.
  • the aerosolizable agent further comprises at least one of the following binder and/or gelling agents:
  • each of the binder and/or gelling materials can be used alone. Further it is conceivable that at least two of the materials can be combined. Preferably, also materials can be used which are mentioned in the substance groups of the above-mentioned materials.
  • the binder material is preferably used as an ingredient to thicken the consistency of the vapour generating component. Thereby the vapour generating material preferably has a firmer consistency and preferably does not flow directly into the filter material of the aerosol generating article and/or into the aerosol generating device upon dissolving the shell of the tobacco article.
  • the tobacco particles themselves can be used as a binder, whereby it is conceivable that they must have a special particle size for such a function.
  • the mixing ratio between vapour generating material and tobacco particles must also be correct so that the tobacco particles can bind the vapour generating material.
  • the aerosol former, the binder and the tobacco particles are mixed in a certain ratio to obtain the aerosol former.
  • a preferred mixture for the aerosolizable agent comprises 13% cellulose, 14% carrageenan, 12% polypropylene glycol and 61% tobacco material. It is conceivable that the mixture comprises 10-15% cellulose, 10-20% carrageenan, 10-20% polypropylene glycol and 60-70% tobacco material.
  • Another preferred mixture for the aerosolizable agent comprises 11% gellan gum, 10% alginate, 12% polypropylene glycol and 67% tobacco material. It is conceivable that the mixture comprises 10-20% gellan gum, 5-15% alginate, 10-20% polypropylene glycol and 60-70% tobacco material.
  • the aerosolizable agent is enclosed by a shell, wherein the shell is preferably decomposable by heat. It is further conceivable that the shell is also aerosolizable by heat. This would minimize waste production compared to shells and or capsules which are replaced.
  • the shell comprises a hydrocolloidal material which has a melting point between 55°C to 100°C, more preferably between 60°C to 90°C and most preferably between 60°C to 80°C.
  • the shell can also be dissolvable at various other temperatures.
  • the temperature at which the shell is dissolvable matches the heating temperature of the aerosol generating device in which the tobacco product is used.
  • the shell comprises at least one of the following hydrocolloidal materials: Alginate, cellulose, gelatin, carrageenan, gelan gum, guar gum, arabic gum, xanthan gum, pectin and/or combinations the materials.
  • each of the shell materials can be used alone. Further it is conceivable that at least two of the materials can be combined. Preferably, also materials can be used which are mentioned in the substance groups of the above-mentioned materials. It is conceivable that the shell also comprises water as an ingredient.
  • a preferred mixture for the shell comprises 80% pectin and 20% water. It is conceivable that the mixture for the shell comprises 70-90% pectin and 10-30% water. Preferably the thickness of the shell is 10 microns. It is conceivable that the thickness of the shell depends on the used shell material and/or mixture. Also preferably, the thickness of the shell is also based on the plastic formability of the aerosolizable agent.
  • the tobacco product comprises at least one non-tobacco flavour.
  • the non-tobacco flavour is mixed within the aerosolizable agent.
  • the tobacco product comprises various non-tobacco flavours.
  • the tobacco product comprises a synthetic tobacco flavour or a tobacco syrup such as described in co-pending patent application no. PCT/EP2020/081767 to enhance the taste of the tobacco particles.
  • the aerosol former comprises a semi-liquid and/or pasty consistency. It is conceivable that the consistency of the aerosol former depends on the amount of binding and/or gelling material which is mixed with the vapour generating component. Preferably the mixing of the aerosol former and the tobacco particles also leads to a semi-liquid and/or pasty consistency of the aerosolizable agent. It is conceivable that the tobacco particles function as a binder by having such a small particle size that combining them with the aerosol former results in a pasty form of the aerosolizable agent.
  • the tobacco product comprises particles, preferably metal particles, which generate heat on contact with an electromagnetic and/or induction field.
  • these particles are not harmful to health and also preferably they don't affect the taste of the tobacco product.
  • these particles are not consumed and remain after use of the tobacco product.
  • the aerosol generating device for using the tobacco product generates an induction field to heat the tobacco product.
  • this induction field only exists in the inside of the device and very preferably only inside the heating section of the device.
  • the body of the device is made of a material which does not interact with the induction field, preferably as few parts of the device as possible are affected by an induction field to minimize losses and/or heating of unintended parts. It is conceivable that due to the induction field, the tobacco product is also heatable from the inside. This leads to a more even heating of the tobacco product compared to just heating it from the outside.
  • the tobacco product can be used in an aerosol generating article, wherein the aerosol generating article comprises at least one tobacco section and at least one filter section with a filter.
  • the aerosol generating article is an aerosol generating article for an aerosol generating device for generating an inhalable aerosol when heated, wherein the article comprises at least one tobacco section and preferably also a filter section.

  • the tobacco strands or shreds may be obtained by cutting or shredding reconstituted tobacco sheets obtained by paper forming, extrusion or casting.
  • tobacco is ground up into a fine powder and mixed with water, binders, additives, humectants and optional wood pulp fibres.

  • the aerosol former of the aerosolizable agent generates vapour, wherein the tobacco particles preferably cause a natural taste experience for a consumer.
  • the shell of the tobacco product decomposes slower by using it with an aerosol generating product, because the heat of aerosol from the aerosol generating product heats the tobacco product slower than by the direct heat of the heated cavity.

Such release can be delayed compared to the time the aerosol 13 starts to be released from the tobacco section 11. As a result, the possible reduction of the tobacco taste from the tobacco section 11 can be compensated at least partially by the release of flavour from the tobacco product 2. Overall, the flavour of tobacco in the aerosol 13 can be evened or modulated as desired during the vaping period.
