Definitions

  • the present invention relates to a non-heating type flavor inhaler and a liquid for atomization for a non-heating type flavor inhaler.
  • a non-combustion flavor inhaler uses, as an aerosol source, glycerol, propylene glycol, or water.
  • Patent Literature (PTL) 1 discloses an electronic cigarette that heats a liquid material containing glycerin.
  • PTL 2 discloses a non-combustion flavor inhaler including capsules that contain water, a triglyceride, and a flavor, where a user inhales the flavor inside the capsules by breaking the capsules. In this case, the triglyceride acts as a diluent for the flavor.
  • PTL 3 discloses an inhibitor of peristalsis in gastrointestinal tract smooth muscle, containing water, a triglyceride, and an emulsifier but does not suggest anything about flavor inhalation.
  • GB 2524856 A is concerned with a pulmonary delivery apparatus comprising: a first chamber adapted to thermally vaporize a quantity of a first liquid to form a relatively warm first vapor (B) and a second chamber adapted to atomize a quantity of a second liquid without heating of the second liquid to form a mist of a relatively cold second vapor (A).
  • a pulmonary delivery apparatus comprising: a first chamber adapted to thermally vaporize a quantity of a first liquid to form a relatively warm first vapor (B) and a second chamber adapted to atomize a quantity of a second liquid without heating of the second liquid to form a mist of a relatively cold second vapor (A).
  • an active ingredient such as nicotine
  • an inert liquid such as a water-glycol mixture
  • the carrier liquids can comprise one of more of the group comprising solubilizers, solvents and mixtures thereof such as water, alcohols such as glycerol, propylene glycol, polyethylene glycol, vegetable oils, mineral oils, lipids, and cyclodextrins.
  • solubilizers such as water, alcohols such as glycerol, propylene glycol, polyethylene glycol, vegetable oils, mineral oils, lipids, and cyclodextrins.
  • the excipient, carriers or substances can be water: terpenes, such as menthol; alcohols, such as ethanol, propylene glycol, glycerol and other similar alcohols; dimethylformamide; dimethylacetamide; wax; supercritical carbon dioxide; dry ice; lipids, triglycerides, acids, surfactants and mixtures or combinations thereof.
  • an aerosol delivery device which includes a chamber having an upstream opening and a downstream opening which allow gas to flow through the chamber, and a heat-conductive substrate located at a position between the upstream and downstream openings. Formed on the substrate is a drug composition film.
  • a heat source in the device is operable to supply heat to the substrate to produce a substrate temperature greater than 300°C, and to substantially volatilize the drug composition film from the substrate.
  • US 2012/192861 A1 is concerned with formulations of pirfenidone or pyridone analog compounds for aerosolization.
  • a glycerol- or propylene glycol-based aerosol source is used from a viewpoint of obtaining a stable aerosol.
  • an aerosol source needs to have low viscosity in view of efficient aerosol generation, and thus, a water-based aerosol source is used.
  • the present inventors found that when a water-based aerosol source is used, visible smoke exhibits low visibility and a short duration time compared with cases in which a glycerol- or propylene glycol-based aerosol source is used, and as a result, a user might not be fully satisfied.
  • an object of the present invention is to provide a non-heating type flavor inhaler that can form visible smoke exhibiting high visibility and a long persistent state of high visibility.
  • the present inventors found that the object is attained by using a liquid for atomization containing a water-based aerosol source, a triglyceride, and an emulsifier.
  • the object is attained by a non-heating type flavor inhaler and a liquid for atomization for a non-heating type flavor inhaler as defined in the appended claims.
  • the present invention relates to: A non-heating type flavor inhaler including
  • a liquid for atomization for a non-heating type flavor inhaler containing a triglyceride, an emulsifier and a water-based aerosol source, the aerosol source containing 70 weight% or more of water, and wherein the triglyceride has an aliphatic group that is derived from a fatty acid and that has a carbon number of 6 or more.
  • a triglyceride is a compound in which three hydroxy groups of glycerol are esterified with fatty acids and is represented by the following formula.
  • R 1 to R 3 are aliphatic groups derived from fatty acids, and the carbon numbers are not limited as long as at least one of R 1 to R 3 is a group having the carbon number of 6 or more. However, at least two of R 1 to R 3 are preferably groups having the carbon number of 6 or more, and all of R 1 to R 3 are more preferably groups having the carbon number of 6 or more.
  • the upper limit of the carbon number is not limited but is preferably 12 or less. When the carbon number is excessively large, dispersion stability in a liquid decreases. In light of this, three aliphatic groups of a triglyceride preferably have the carbon number within the above-mentioned range.
  • a triglyceride in which all of R 1 to R 3 are groups having the carbon number of 6 or more is also called a medium-chain triglyceride.
  • Such a medium-chain triglyceride has a feature that a user does not feel the taste or flavor during smoking.
  • the concentration of a triglyceride in a liquid for atomization is not limited. However, when the concentration of a triglyceride is excessively high, the viscosity of the liquid increases. This causes a problem in which the amount to be atomized decreases in a non-heating type flavor inhaler that utilizes vibrations, such as ultrasonic vibrations.
  • the upper limit of the concentration in a liquid for atomization is preferably 10 weight% or less and more preferably 5 weight% or less. Meanwhile, the lower limit of the concentration is not limited but is preferably 1 weight% or more and more preferably 2 weight% or more.
  • An emulsifier has an affinity with water in a liquid for atomization and a triglyceride as a hydrophobic substance.
  • any publicly known emulsifier can be used, and examples include anionic surfactants (sodium lauryl sulfate and alkyl ether carboxylates, for example), cationic surfactants (benzalkonium chloride, for example), amphoteric surfactants (lecithin, for example), and nonionic surfactants (polyglycerol fatty acid esters, sucrose fatty acid esters, calcium stearoyl lactylate, sorbitan fatty acid esters, propylene glycol fatty acid esters, polyoxyethylene alkyl ethers, polyoxyethylene sorbitan fatty acid esters, and saponins, for example).
  • anionic surfactants sodium lauryl sulfate and alkyl ether carboxylates, for example
  • cationic surfactants benzalkonium chloride,
  • the concentration of an emulsifier in a liquid for atomization is not limited but is preferably 2 weight% or less and more preferably 1 weight% or less.
  • the lower limit of the concentration is not limited but is preferably 0.1 weight% or more and more preferably 0.2 weight% or more.
  • a water-based aerosol source is used.
  • the expression of "water-based” herein means that 70 weight% or more of water is contained in an aerosol source. Water preferably accounts for 80 weight% or more relative to the entire aerosol source. Exemplary aerosol sources other than water include glycerol and propylene glycol. The amount of these is preferably 30 weight% or less and more preferably 20 weight% or less in an aerosol source. Alternatively, an aerosol source may solely consist of water. Moreover, water preferably accounts for 70 weight% or more in a liquid for atomization. Since water preferably contains no impurity, deionized water or the like may be used.
  • a liquid for atomization used in the present invention may contain any flavor publicly known in the field concerned. Such a flavor is not limited, and examples include menthol.
  • the amount may be a publicly known amount but is preferably 8 weight% or less and more preferably 5 weight% or less in a liquid for atomization.
  • the lower limit of the concentration is not limited, and other components (flavor) need not be contained.
  • a liquid for atomization used in the present invention does not contain nicotine in an embodiment.
  • a liquid for atomization 1 originally has a structure in which an oil droplet 4 of a hydrophobic substance (triglyceride) having a low vapor pressure is finely dispersed in a water-based aerosol source 2. Such oil droplets exist in a stable manner by means of an emulsifier 6. The liquid for atomization is then atomized to form an atomized product of aggregated particles 1'.
  • a hydrophobic substance triglyceride
  • the diameter of the particles 1' is 0.1 to 10 ⁇ m, and the diameter of oil droplets 4 present within each particle 1' is 0.01 to 1 ⁇ m.
  • oil droplets 4 act as nuclei and suppress vaporization of the surrounding aerosol source 2. Further, due to the low vapor pressure, oil droplets 4 alone remain there without vaporization even after the aerosol source 2 is vaporized. Consequently, it is presumed that the visibility of visible smoke is enhanced and the duration time of such a high visibility state increases.
  • a non-heating type flavor inhaler is an apparatus that makes a flavor component contained in a liquid for atomization inhalable and that includes at least a liquid storage section for storing the liquid for atomization and an atomization section for atomizing the liquid for atomization.
  • the flavor inhaler is thus used in the state in which the liquid storage section is filled with the liquid for atomization.
  • the non-heating type flavor inhaler includes a mouthpiece for facilitating inhalation.
  • the atomization section may have a vibration generating mechanism that can apply vibration to the liquid for atomization. Such an atomization section having a vibration generating mechanism is preferable since atomization efficiency is high.
  • the atomization section preferably does not have a heating mechanism.
  • a heating mechanism herein means a mechanism that can alone atomize a liquid for atomization. For example, the temperature of a liquid rises in some cases when vibration is applied by a vibration generating mechanism. In this case, however, such a vibration generating mechanism is not regarded as a heating mechanism.
  • auxiliary heating mechanism herein means a heating mechanism that can heat a liquid for atomization but cannot alone atomize the liquid for atomization.
  • exemplary auxiliary heating mechanisms include a heating mechanism that does not heat a liquid for atomization to its boiling point.
