Definitions

  • the present invention relates to the use of a tobacco filler for a non-combustion smoking article and a non-combustion smoking article which is filled with the tobacco filler.
  • non-combustion smoking articles that replace cigarettes and allow experience of a smoke flavor without combusting tobacco have been developed, and one in which a smoke flavor component and a component capable of generating aerosol fill a pod-shaped container for use or one having a heat source at a tip thereof is typically known.
  • US 2011/232657 A1 is concerned with encapsulated tobacco beads which are used in snus type products and/or smoking articles likes cigarettes.
  • the tobacco beads may contain 0.001 to 5 wt.% of a humectant, and they may contain antioxidants and/or preservatives, which may inter alia be selected from ascorbic acid.
  • US 5,713,376 provides a tobacco product comprising nicotine in an amount below about 0.01 milligram per gram.
  • the tobacco product contains a small amount of propylene glycol as a flavourant and a mixture of ascorbic acid, citric acid and maleic acid for oxidizing nicotine.
  • EP 1 723 858 A1 provides a smoking composition for a hookah.
  • the tobacco material may contain propylene glycol as a humectant and ascorbic acid as a flavourant.
  • GB 2 203 022 A inter alia describes a process for culturing tobacco cells having an enhanced level of nicotine.
  • the smoking material may contain an antioxidant, which may be ascorbic acid, and it may contain a humectant, which may among others be propylene glycol.
  • the material may contain a humectant like glycerin or propylene glycol.
  • Ascorbic acid or isoascorbic acid may be used as a reducing agent for treating the tobacco.
  • the amount of evaporation of smoke flavor components may be insufficient compared to that from cigarettes or a user may feel so-called "smoke flavor inhibition".
  • An object of the present invention is to provide a tobacco filler which is used for a non-combustion smoking article that can suppress a reduction in an amount of evaporated smoke flavor components and suppress "smoke flavor inhibition" in a non-combustion smoking article, particularly a smoking article in which a filler containing shredded tobacco is heated.
  • the inventors of the present invention carried out an extensive study in order to solve the problem and, as a result, found that by adding an acid fulfilling specific conditions to a tobacco filler, a reduction in the amount of evaporated smoke flavor components may be suppressed and "smoke flavor inhibition" may be suppressed, thereby completing the present invention.
  • the present invention is defined in the appended claims. It relates to:
  • a reduction in the amount of evaporated smoke flavor components may be suppressed and "smoke flavor inhibition" may be suppressed in a non-combustion smoking article in which a filler containing shredded tobacco is heated.
  • the tobacco filler used for a non-combustion smoking article contains shredded tobacco, and liquid that generates aerosol, and is characterized in that the tobacco filler contains an acid that has a first acid dissociation constant of 4.0 to 6.0 inclusive and a boiling point of 366°C to 600°C inclusive.
  • the inventors of the present invention have revealed various issues on non-combustion smoking articles, particularly smoking articles in which a filler containing shredded tobacco is heated.
  • the amount of evaporated smoke flavor components may be reduced. This may be caused by penetration of added acid into shredded tobacco together with liquid that generates aerosol and formation of salts with smoke flavor components in shredded tobacco.
  • salts may be dissociated by heating or a reduction in the amount of evaporated smoke flavor components may be suppressed due to high temperature, while the influences may be significant in non-combustion smoking articles which are heated to low temperature.
  • smoke flavor inhibition such as receiving a stimulus that is different from tobacco or generating physiological spontaneous actions such as “choking”. This may be caused by components that inhibit smoke flavor in a filler, and volatilization of the components together with solvents such as propylene glycol may cause "smoke flavor inhibition”.
  • the inventors of the present invention revealed that formation of salts from acids and smoke flavor components in shredded tobacco is correlated with the first acid dissociation constant (pKa 1 ) representing the strength of acid and formation of salts may be suppressed by selecting an acid having a first acid dissociation constant within a specific range, and less chemical odor (chemical smell) may be sensed by selecting an acid having a boiling point at or above a certain temperature.
  • pKa 1 the first acid dissociation constant representing the strength of acid and formation of salts
  • the inventors of the present invention found that by adding an "acid that has a first acid dissociation constant of 4.0 to 6.0 inclusive and a boiling point of 366°C to 600°C inclusive" to a tobacco filler, a reduction in the amount of evaporated smoke flavor components may be suppressed and "smoke flavor inhibition" may be suppressed.
  • the "first acid dissociation constant” means an acid dissociation constant in water at normal temperature (25°C).
  • boiling point means a boiling point at pressure of 760 mmHg.
  • non-combustion smoking article "shredded tobacco”, “liquid that generates aerosol”, “acid that has a first acid dissociation constant of 4.0 to 6.0 inclusive and a boiling point of 366°C to 600°C inclusive” and the like are hereinafter specifically described.
  • the tobacco filler used according to the present invention for a non-combustion smoking article contains shredded tobacco, and liquid that generates aerosol.
  • the non-combustion smoking article which is filled with the tobacco filler is not particularly limited, for example, as to the specific structure thereof, and may appropriately be any well-known non-combustion smoking article.
  • the non-combustion smoking article is hereinafter described by way of specific examples.
  • non-combustion smoking article examples include the one that has the structure as a non-combustion smoking article 10 illustrated in Fig. 1.
  • Fig. 1 is a section view of the cylindrical non-combustion smoking article 10 along the longitudinal direction.
  • the non-combustion smoking article 10 has the structure having a battery 101, a pod 103 that accommodates a filler 102 and a heater 104 and a mouthpiece 105. By filling the pod 103 with the tobacco filler and heating the same, aerosol is generated.
  • the heating temperature of the tobacco filler in the non-combustion smoking article is generally 22°C or higher, preferably 100°C or higher and more preferably 150°C or higher, and generally 350°C or lower, preferably 300°C or lower and more preferably 250°C or lower.
  • the non-combustion smoking article having a heating temperature of a tobacco filler within the above range tends to have an issue of "smoke flavor inhibition", and thus characteristics of the tobacco filler may be more efficiently exploited.
  • Examples of the type of the shredded tobacco include flue-cured tobacco, Burley tobacco, Japanese domestic tobacco, and regenerated tobacco.
  • Examples of the region used include the leaf (expanded tobacco), stem, rib (cut stem), root, and flower.
  • the dimension of the shredded tobacco is not particularly limited.
  • the shredded tobacco preferably has a sphere equivalent diameter of generally 1.5 mm or less and preferably 0.5 mm or less and generally 0.01 mm or more as measured by a projected sectional-area method (such as the method using Camsizer (Retsch Technology GmbH)).
  • the tobacco filler contains shredded tobacco at 20% by mass or more, preferably 30% by mass or more and more preferably 40% by mass or more, and 80% by mass or less, preferably 70% by mass or less and more preferably 60% by mass or less.
  • the content within the above range allows easier suppression of a reduction in the amount of evaporated smoke flavor components and more effective suppression of "smoke flavor inhibition".
  • the liquid that generates aerosol contains propylene glycol.
  • Further examples of the liquid that generates aerosol include polyhydric alcohols such as glycerol, triethylene glycol and tetraethylene glycol; aliphatic esters of carboxylic acids such as methyl stearate, dimethyl dodecanedioate and dimethyl tetradecanedioate.
  • the liquid used may be a combination of two or more.
  • the liquid that generates aerosol contains propylene glycol.
  • Propylene glycol is used for food and medicinal products as a highly safe solution and can easily generate visible smoke because of the low boiling point and liability of vaporisation. Meanwhile, propylene glycol has high vapour pressure, and thus is liable to volatilise in the oral cavity. Because of this, propylene glycol may create an atmosphere in which components inhibiting smoke flavor contained in aerosol are liable to volatilise, thereby more easily causing an issue of "smoke flavor inhibition". Consequently, characteristics of the tobacco filler may be more efficiently exploited.
  • the tobacco filler contains liquid that generates aerosol at 20% by mass or more, preferably 30% by mass or more and more preferably 40% by mass or more, and 80% by mass or less, preferably 70% by mass or less and more preferably 60% by mass or less.
  • the content within the above range allows easier suppression of a reduction in the amount of evaporated smoke flavor components and more effective suppression of "smoke flavor inhibition".
  • the tobacco filler is characterised in that the tobacco filler contains an acid that has a first acid dissociation constant of 4.0 to 6.0 inclusive and a boiling point of 366°C to 600°C inclusive (hereinafter also abbreviated as "acid").
  • the acid has a first acid dissociation constant of preferably 4.5 or more and preferably 5.5 or less.
  • the acid has a boiling point of preferably 400°C or higher and preferably 560°C or lower.
  • the first acid dissociation constant and the boiling point within the above ranges allows more effective suppression of "smoke flavor inhibition".
  • the acid is at least one selected from ascorbic acid, isoascorbic acid, heneicosanoic acid, lignoceric acid, octacosanoic acid, and nonadecanoic acid.
  • ascorbic acid and isoascorbic acid are particularly preferred.
  • the acid as described above allows easier suppression of a reduction in the amount of evaporated smoke flavor components and more effective suppression of "smoke flavor inhibition".
  • the tobacco filler contains the acid at 0.25% by mass or more and preferably 1% by mass or more and 10% by mass or less.
  • the content within the above range allows easier suppression of a reduction in the amount of evaporated smoke flavor components and more effective suppression of "smoke flavor inhibition".
  • the tobacco filler contains shredded tobacco, and liquid that generates aerosol.
  • components contained in shredded tobacco such as water elute in the liquid that generates aerosol, and thus it can be regarded that the tobacco filler also contains water.
  • the tobacco filler contains water at generally 5% by mass or more, preferably 7.5% by mass or more and more preferably 10% by mass or more, and generally 30% by mass or less, preferably 25% by mass or less and more preferably 20% by mass or less of the whole tobacco filler.
  • the content within the above range allows easier suppression of a reduction in the amount of evaporated smoke flavor components and more effective suppression of "smoke flavor inhibition".
  • Shredded tobacco used was obtained by grinding tobacco in a household mixer followed by shaking on a sieve (AS200, manufactured by Retsch Technology GmbH) under the condition: amplitude-1.5 mm/"g" for 2 minutes, and had a mesh size of 0.5 mm or less.
  • the prepared sample was placed so as to attach to a pod dedicated to a product with the product name "Ploom ® " marketed by Japan Tobacco Inc., and stored for 2 days or more under the conditions of 22°C and humidity of 60%. It was verified that the heating temperature (during stable operation) of shredded tobacco using Ploom was about 160°C to 170°C by preliminary measurement using a thermocouple.
  • the prepared pod was attached to Ploom and the amount of evaporated smoke flavor components during initial 10 puffs was measured under specified smoking conditions (55 ml/2s, smoking interval: 30s) on a smoking machine (Borgwaldt, RM-26).
  • the indicative component selected was nicotine, which can be easily measured as a smoke flavor component.
  • Smoke was trapped with a Cambridge filter pad, the smoke trapped on the filter was extracted in a methanol solvent while shaking for 40 minutes and nicotine was assayed by GC-FID.
  • Fig. 2 indicates a graph illustrating the relationship between the first acid dissociation constant of acids and the amount of evaporated smoke flavor components. From Fig. 2 , it resulted that acids having low first acid dissociation constant had low amounts of smoke flavor components, and for most of acids having an acid dissociation constant of 4.0 or more, the amounts of smoke flavor components were equivalent to the amount of smoke flavor components without addition of acid. From this result, it was found that by using an acid having a first acid dissociation constant of 4.0 or more, the amount of evaporated smoke flavor components does not decrease. As most of acids have a first acid dissociation constant or 6.0 or less by taking the pH of acids into account, the ideal range of the first acid dissociation constant is 4.0 to 6.0 inclusive.
  • Fig. 3 indicates a graph illustrating the relationship between the boiling point of acids having a first acid dissociation constant of 4.0 to 6.0 inclusive and smoke flavor inhibition. It was found that at a boiling point of 366°C or higher, smoke flavor inhibition could be reduced with almost all acids, and thus the boiling point was important for reduction of smoke flavor inhibition.
  • Fig. 4 indicates a graph illustrating the relationship between the boiling point of acids having a first acid dissociation constant of 4.0 to 6.0 inclusive and chemical odor. It was found that chemical odor decreased with acids having a boiling point of 366°C or higher. When the boiling point of acid is too high, the amount of acid released by heating decreases, and thus it is believed that the boiling point is preferably 600°C or lower.
  • test was carried out in the same manner as in previous Examples except that the contents of acids, isoascorbic acid, lignoceric acid and nonadecanoic acid, were changed from 5% by mass in previous Examples to 3% by mass or 1% by mass. In the present evaluation, only an effect on smoke flavor inhibition was focused because the amounts of evaporated smoke flavor components are equivalent.
  • Fig. 5 indicates a graph illustrating the relationship between the acid content and smoke flavor inhibition. From Fig. 5 , it may be observed that even when the content is reduced to 1% by mass, the effect of acid is high. This is merely because a highly effective acid can exhibit the effect at a low content. Because acids such as isoascorbic acid, lignoceric acid and nonadecanoic acid have high boiling points, the acids tend to be evaporated by heating, generate aerosol by condensation and remain in particles, and it is predicted that a high effect is obtained because the acids remain in aerosol even after dilution in the oral cavity during smoking. When the acid content is excessive, characteristics of acid may be noticeable, and thus a suitable content may be 10% by mass or less.
  • the test was carried out in the same manner as in previous Examples and Comparative Examples except that the liquid that generates aerosol was varied.
  • the solvents which were liquids that generate aerosol used were, in addition to propylene glycol, glycerol, diacetin and triethyl citrate (TEC), and the acid used was nonadecanoic acid.
  • TEC triethyl citrate
  • the results are shown in Fig. 6 .
  • propylene glycol was used, the highest smoke flavor inhibition was obtained and the smoke flavor inhibition was low for other liquids. This indicates that the liquid that generates aerosol which is likely to exhibit the highest effect is propylene glycol, and the present technology is effective when a whole or a small amount of the liquid contained is propylene glycol.
  • the tobacco filler may fill a non-combustion smoking article for smoking.
