Definitions

  • the present application relates to a new smoking article, typically a cigarette-like smoking article which has reduced emissions for the smoker compared to articles of the art.
  • a smoking article should fulfil the four Requirements of the cigarette that are (i) a pleasant taste, (ii) a psychoactive effect, mainly done by nicotine, (iii) a ritual, in particular with initial lighting, (iv) a social role, allowing sharing, mostly due to a low unit cost. Reduced toxicity is an extra step on these Requirements.
  • Filtered cigarettes are one of the first approaches explored and developed in the fifties. If they were widely accepted by smokers, their toxicity was not dramatically reduced because of compensatory phenomenon on drawing and smoking habits (such as depth of inhalation, volume and number of puffs per cigarette). Ventilated filter, launched in the seventies, suffered the same drawbacks.
  • Electronic cigarette is an electronic inhaler that vaporizes a liquid solution, generally containing nicotine and flavourings, into an aerosol mist. Often, a LED lights up at the distal end when air is drawn through the device to simulate classic cigarette smoking.
  • Similar Smokeless Cigarettes® consist of a hollow tube with nicotine-containing foam. Some vapour is released when air is drawn through. However these products are not satisfactory from ritual, aesthetic and taste smoker's points of view.
  • Heating tobacco without any combustion of the smoked device was also considered, using either an external gas (EP 1 441 607 Bl) or an electrical heater [Accord® (US 5,649,554) and Heatbar® (US 6,810,883 B2)].
  • an external gas EP 1 441 607 Bl
  • an electrical heater Accord® (US 5,649,554) and Heatbar® (US 6,810,883 B2).
  • Such a technology requires introducing a special cigarette into the heating device and this step deeply alters the smoking ritual.
  • None of the previously described existing products are able to efficiently and pleasantly burn a mostly non-tobacco combustible on a sufficient length, preferably on at least 4 cm, and, in the same time, deliver a nice taste.
  • this product is not able to balance the psychoactive compound(s) absorption, most efficient in the lungs, and the required maintaining of the flavour(s)' taste, felt in the mouth.
  • the same absorption problem occurs when nicotine is added to the combustible to fulfil the role of flavour and psychoactive at the same time.
  • Inventors now herein provide an advantageous smocking device based on a new concept wherein the act of smoking is in three different formal actions, which are (i) the generation of heat, (ii) the generation of an aerosol loaded with psychoactive substances and (iii) the generation of a pleasant taste. These three formal actions are done in the same steps in the ordinary cigarette.
  • the smoking article of the invention is less toxic than existing cigarette, enjoyable for smokers (ritual, taste, psychoactive action) and also easy to industrially produce for a low unit cost.
  • a first object of the present invention is a smoking article comprising two compartments, wherein
  • a first distal compartment comprises a combustible material producing heat, and at least one psychoactive compound
  • a second proximal compartment comprises at least one aromatic element.
  • proximal part or “proximal compartment” refers to the nearest part or compartment of the mouth compared to another considered element; and a “distal part” or “distal compartment” refers to the farthest part or compartment of the mouth compared to another considered element.
  • the smoking article comprises nicotine as the at least one psychoactive compound contained in the distal compartment.
  • the combustible material is not tobacco or comprises no more than about 35% of tobacco, preferably no more than about 10%, even more preferably no more than about 5%.
  • the combustible material of the distal compartment is a carbonized material, preferably obtained from pyrolizis of a lignocellulosic material, such as cellulose, or of a synthetic polymer, such as viscose.
  • Said combustible material may further comprise at least one of a loading agent and a combustion rate controller.
  • the at least one psychoactive compound in the distal compartment is selected from nicotine, a minor tobacco alkaloid, a therapeutic psychoactive compound and equivalents thereof.
  • the distal compartment may further comprise monoamine oxidase inhibitor, levulinic acid and/or a mixture of different psychoactive compounds.
  • the at least one aromatic element preferably comprises tobacco and is located inside the proximal compartment.
  • the aromatic element(s) may be natural or artificial. More particularly, artificial aromatic element is preferably menthol, and natural aromatic element is preferably selected from a tobacco material selected from Latakia, Oriental and Burley; a vegetal material selected from cichorium, mint, vanilla, lavender, liquorice, coffee, cocoa, tea, eucalyptus, carob, bergamot, melilotus, orange blossom, yerba mate, anise, cardamom, chili pepper, cinnamon, coriander, cumin, ginger, paprika, pepper, saffron, star anise, thyme, clove, curcuma; any extract thereof; and any mixture thereof.
  • the distal compartment may also comprise an aromatic element.
  • an irritation modulator is added to the combustible, in the distal compartment.
  • the proximal compartment further comprises a filter absorbing any undesirable elements of the smoke gaseous phase.
  • the filter may comprise activated charcoal, activated silica and/or a zeolite.
  • the proximal compartment contains two distinct sub-compartments, respectively, first and second sub- compartment, wherein the second sub-compartment comprises or corresponds to the filter, and the first sub-compartment comprises the at least one aromatic element.
  • the first sub-compartment is closer to the mouth (proximal) than the filter absorbing any undesirable elements.
  • the smoking article may produce smoke, and said smoke is preferably generated during combustion, typically by a compound added to the combustible.
  • a compound added to the combustible can be further added to the proximal compartment.
  • the said added compound may be, for instance, a polyol, and/or a low-to-medium volatility ester.
  • the smoking article according to the invention further comprises an aesthetical element to be introduced in the mouth.
  • the smoking article may comprise a wrapping material, possibly a perforated wrapping material, said perforated material surrounding preferably the proximal compartment.
  • the design of the smoking article of the invention allows the creation of a tailored smoke. More particularly, the burning of the combustible produces heat. Under this heat, the psychoactive compounds undergo a distillation-condensation process, which yields a psychoactive aerosol. Such an aerosol is able to reach lungs, and thus be absorbed pulmonary, which is the quickest way of absorption. An optional filter removes the smelly compounds, which may be created by the combustion. The flavour is generated under a mild heat, mostly in a vapour form, and thus has taste and smell for the smoker.
