Definitions

  • the following description relates to a non-heating type smoking article comprising a semi-solid medium part.
  • a large number of smoking articles have recently been proposed in which the smoking articles are heated rather than combusted. Unlike conventional smoking articles, these non-combustion type smoking articles are used by sucking an aerosol generated by heating the cigarette medium without burning a cigarette medium. As one of the types of such heating type smoking articles, there is a smoking article using electrical heating.
  • the delivery of nicotine through the non-heating type electronic cigarette method is mainly used in a state in which it is dissolved in a liquid substance, or changed to a sublimable nicotine free base form and then migrated by inhalation using the property of being self-vaporized.
  • nicotine in the form of a free base may have a possibility of losing components due to the nature of continuously sublimating.
  • Patent Document 1 Korean Patent Publication No. 2021-0017296
  • the present disclosure provides a non-heating type smoking article comprising:
  • the aerosol-generating material may be one or more selected from the group consisting of propylene glycol, glycerin, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, and tetraethylene glycol.
  • the semi-solidifying agent may be one or more selected from the group consisting of gelatin, starch, polysaccharide, pectin, cellulose, cellulose derivative, carboxymethyl cellulose, and alginate.
  • the semi-solid medium part may be adsorbed to a porous material.
  • the porous material may be one or more selected from the group consisting of aerogel, zeolite, and silica.
  • the filter part may contain an acetate material.
  • an aerosol-generating system comprising:
  • any member when any member is said to be located “on” the other member, this not only includes a case where the any member is in contact with the other member, but also includes a case where another member exists between the two members.
  • upstream refers to a portion where air is drawn from the outside of the smoking article to the inside thereof when the user inhales outside air using the smoking article
  • downstream refers to a portion where air exits from the inside of the smoking article containing a combustible heat source to the inside thereof.
  • upstream and downstream may be used in order to indicate the relative position or direction between parts or segments that make up the smoking article.
  • the "aerosol-generating device” may mean a device capable of generating an aerosol.
  • the aerosol contains volatile compounds.
  • the present disclosure provides a non-heating type smoking article 1000 comprising: a semi-solid medium part 100; a paper tube part 200; and a filter part 300, wherein the semi-solid medium part is a semi-solid phase containing nicotine and an aerosol-generating material.
  • the semi-solid medium part contains nicotine and an aerosol-generating material and has a semi-solid phase.
  • the semi-solid phase may be formed through a semi-solidifying agent, and may be, for example, a water-based gel type, a paste type, an ointment type, or the like.
  • the semi-solid phase may include, for example, a semi-solidifying agent such as gelatin, starch, polysaccharide, pectin, cellulose, cellulose derivative, carboxymethyl cellulose, alginate, or the like, but is not limited to the above-mentioned types.
  • the above-mentioned “semi-solid phase” is a state in which fluidity is lost. Specifically, even if the container is tipped sideways after the medium is accommodated in a container, the above-mentioned “semi-solid phase” is a state in which the composition is not diffused to the entirety of the container side surface that becomes the lower side after being tipped sideways, and the state can be visually confirmed.
  • the semi-solidifying agent may be contained in an amount of 5 to 40% by weight based on the total weight of the semi-solid medium part.
  • the semi-solidifying agent may be contained in an amount of less than 5% by weight, it may be possible to have a phase close to the liquid phase while the fluidity of the semi-solid medium part increases, and when the semi-solidifying agent is contained in an amount exceeding 40% by weight, it may affect the migration of nicotine contained in the medium part. It is not limited to the above range, but more preferably, the semi-solidifying agent may be contained in an amount range of 10 to 30% by weight that can smoothly migrate nicotine while having excellent properties.
  • the semi-solid medium part obtained by comprising the semi-solidifying agent may have a viscosity of 2,000 mPa ⁇ s to 90,000 mPa ⁇ s at 25°C. If the viscosity is less than 2,000 mPa ⁇ s, the fluidity of the medium part itself also increases so that materials including nicotine may be migrated to other materials of the smoking article, and if the viscosity exceeds 90,000 mPa ⁇ s, the semi-solid medium part has an excessive hardness so that there may be a concern that the migration of nicotine is affected.
  • the viscosity was measured using a rotational viscometer, and the viscosity was measured under each temperature up to 25°C by maintaining a constant stress of 5 Pa, a constant speed of 1 Hz, and a sample injection amount of 3 mL, warming the sample to 80°C and then injecting 3 mL of the sample onto a tray, hanging a contactor, using silicone oil as a sealing system, starting the measurement when the tray temperature reached 80°C.
  • the semi-solid medium part may contain water as a solvent. Water may be contained in an amount of 10 to 40% by weight, and the semi-solidifying agent may be easily mixed with nicotine, an aerosol-generating material, and the like by containing water in the semi-solid medium part. Other additives (flavors, etc.) in addition to the above-described components may be further added to the semi-solid medium part.
  • the "smoking article” may mean any product, which can be smoked regardless of whether or not it is based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes, or any product which can provide smoking experience.
  • the smoking article may refer to a smokable article capable of generating an aerosol in a non-heating manner (non-heating type).
  • the smoking article according to the present disclosure comprises nicotine, an aerosol-generating material, and a semi-solidifying agent contained in the semi-solid medium part.
  • the "aerosol-generating material” may mean a material capable of generating an aerosol.
  • the aerosol-generating material may be a liquid phase.
  • a liquid phase aerosol-generating material may include a liquid phase composition based on a tobacco extract and/or various flavoring agents.
  • the aerosol-generating material may further include a solid phase aerosol-generating material.
  • the solid phase aerosol-generating material may have a configuration that includes solid materials based on tobacco raw materials such as reconstituted tobacco leaf tobacco, cut tobacco, and reconstituted tobacco, but preferably does not include a solid phase aerosol-generating material, and includes nicotine and a liquid phase aerosol-generating material.
  • tobacco raw materials such as reconstituted tobacco leaf tobacco, cut tobacco, and reconstituted tobacco
  • a solid phase aerosol-generating material and includes nicotine and a liquid phase aerosol-generating material.
  • the scope of the present disclosure is not limited to the examples listed above.
  • liquid phase aerosol-generating material may further include at least one of propylene glycol, glycerin, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, and tetraethylene glycol.
  • aerosol-generating material may further comprise at least one of moisture and flavoring material.
  • the aerosol-generating material may be contained in an amount of 5 to 60% by weight based on the total weight of the semi-solid medium part. If the aerosol-generating material is contained in an amount of less than 5% by weight, the amount of atomization may not be sufficient, and if it is contained in an amount of exceeding 60% by weight, smoke may be excessively generated, and it may be affected to maintain the semi-solid phase of the medium part.
  • the aerosol-generating material may further comprise various additives such as cinnamon, capsaicin, and the like.
  • the aerosol-generating material may comprise substances in the form of gels or solids as well as liquid substances with high fluidity.
  • the components of the aerosol-generating material may be variously selected according to embodiments, and the composition ratio thereof may also vary according to the embodiments.
  • the liquid phase may refer to a liquid phase aerosol-generating material.
  • the nicotine after the nicotine is dissolved in the aerosol-generating material, it may be appropriately semi-solidified (e.g., gelated) by a semi-solidifying agent.
  • the semi-solidifying agent may be any one of gelatin, starch, polysaccharide, pectin, cellulose, cellulose derivative, carboxymethyl cellulose, and alginate, but is not limited to the above-mentioned types.
  • the nicotine may be contained in an amount of 0.1 to 20% by weight based on the total weight of the semi-solid medium part, and may be adjusted and contained depending on the type of a smoking article to be manufactured.
  • the nicotine may be contained in the smoking article in a gelated form by a semi-solidifying agent, and unlike nicotine contained in a liquid phase, it does not sublime continuously and can be stably contained.
  • the aerosol-generating material may comprise a pH adjusting agent.
  • the pH adjusting agent may include potassium carbonate, sodium hydrogen carbonate, a mixture thereof, or the like.
  • the pH adjusting agent can adjust the pH of the aerosol-generating material to the alkaline side, thereby enabling the release of flavor components to be facilitated from the aerosol-generating material accordingly.
  • Conventional smoking articles comprising a medium part having a liquid phase contain nicotine in the form of a free base and continuously sublimate nicotine so that it is somewhat difficult to adjust the pH which can increase the volatility of nicotine.
  • the smoking article according to the present disclosure is characterized in that it reduces the sublimation of nicotine due to having a semi-solid phase. That is, the smoking article according to the present disclosure can bring about a rich taste expression effect through pH control. That is, the pH of the medium part of the present disclosure may have a pH of 7 or more, more preferably 8 or more.
  • the semi-solidified semi-solid medium part may be used by being adsorbed to a porous material.
  • the porous material may be any one of aerogel, zeolite, or silica, and is not limited to the above-mentioned materials as long as it is a porous material having a property that the semi-solid medium part in which nicotine and aerosol-generating material as described above are gelled can be adsorbed.

In addition, if the specific surface area is less than 100 cm 3 /g, the semi-solid medium part may not be well adsorbed, and if it exceeds 500 cm 3 /g, nicotine in the semi-solid medium part is excessively adsorbed to the porous material, which may affect nicotine migration.
  • the porous material may be manufactured in a tubular shape so that it may be formed in a form in which a semi-solid medium part is injected into the tubular shaped porous material, or in a form in which the semi-solid medium part is adsorbed to a granular porous material.
  • the form of the porous material is an example, and the semi-solid medium part may be adsorbed and included in other various forms of porous materials.
  • the porous material when the porous material is in a granular form, the porous material may be prepared so that the porous material is agglomerated with the binder by including a binder so that the porous material is stably wrapped and included in a wrapping paper.
