Description

The present disclosure relates to aerosol-generating articles for use in aerosol-generating devices. In particular, the present invention relates to an aerosol-generating article for use in an aerosol-generating device, the aerosol-generating device comprising an odor-suppressing substrate.

Aerosol-generating articles in which an aerosol-forming substrate, such as a tobacco-containing substrate, is heated rather than combusted are known in the art. Typically, in such aerosol-generating articles, an aerosol is generated by transferring heat from a heat source to a physically separated aerosol-forming substrate or material that is in contact with the heat source; or may be located within, around, or downstream of the heat source. During use of the aerosol-generating article, volatile compounds are released from the aerosol-forming substrate by heat transfer from the heat source and entrained into the air drawn through the aerosol-generating article. As the released compounds cool, they condense or nucleate to form an aerosol.

Some prior art aerosol generating articles include a combustible heat source upstream of the aerosol forming substrate. The aerosol-forming substrate may include tobacco. In use, heat from a combustible heat source heats the aerosol-forming substrate and volatilizes compounds, which cool and condense or nucleate to form an aerosol.

The aerosol-forming substrate may be heated by a separate aerosol generator. Many prior art documents disclose aerosol generating devices for use with aerosol generating articles. Such devices include, for example, electrically heated aerosol generators in which the aerosol is generated by heat transfer from one or more electric heater elements of the aerosol generator to an aerosol-forming substrate of a heated aerosol-generating article.

However, it has been found that the process of heating the aerosol-forming substrate may also lead to the generation of undesirable and unpleasant odors. This problem may be particularly pronounced when the aerosol-forming substrate includes tobacco. In some cases, it has been observed that the aerosol generated by the aerosol generator remains in the air and the surrounding environment after the user has finished using the aerosol generator. This is known as off-flavor. In other cases, it has been observed that improper use or maintenance of aerosol generators can lead to distinctive and unpleasant odors. This may occur, for example, when the electric heating element of an aerosol generator is not properly cleaned. This is known as malodour. Both off-flavors and malodors may be experienced both by the user of the aerosol-generating article and by other users in close proximity to the aerosol-generating article.

As a result, it would be desirable to provide an aerosol-generating article that reduces or prevents unpleasant odors, such as off-flavors and malodors, caused by heating of an aerosol-forming substrate.

It may be desirable to provide an aerosol-generating article that reduces or prevents unpleasant odors without the use of very strong fragrances or pleasant scents.

It may be desirable to provide an aerosol-generating article that reduces or prevents unpleasant odors without affecting the flavor of the mainstream aerosol.

The present disclosure relates to aerosol generating articles. The aerosol-generating article includes an aerosol-forming substrate. The aerosol generating article may include an odor control substrate.

The odor control substrate may release at least one odor control molecule to reduce or prevent unpleasant odors generated by the aerosol forming substrate. The odor control substrate may release odor control molecules including odor masking molecules such as perfumes. The odor-suppressing substrate may release odor-suppressing molecules, or a particular combination of odor-suppressing molecules, that are configured to produce an olfactory white. The odor suppressing substrate may emit a combination of odor masking molecules and molecules configured to produce olfactory whiteness.

Providing an odor suppressing substrate may advantageously reduce or prevent the perception of unpleasant odors, such as off-flavors and malodors, caused by heating of the aerosol-forming substrate in an aerosol-generating article.

The odor control substrate may include two or more different odor components. For example, the odor control substrate may include at least 2, at least 3, at least 5, or at least 8 different odor components. The odor control substrate may include at least ten different odor components.

As presented in more detail below, providing an odor control substrate comprising at least ten different odor components may advantageously improve the effectiveness of the odor control substrate to produce an olfactory white. .

According to the present invention, an aerosol-generating article is provided that includes an aerosol-forming substrate and an odor-suppressing substrate. The odor control substrate includes at least ten different odor components.

It is known to use perfumes or pleasant scents to mask or mask unpleasant odors. However, the inventors have shown that the provision of a large number of different odorants, such as 10 different odorants, reduces a subject's ability to distinguish between any of the individual odorants. In this way, a combination of 10 different odor components may produce an "olfactory white". While not wishing to be bound by theory, this effect is a visual effect where a mixture of different wavelengths or colors may be perceived as "white", or a mixture of different sound frequencies may be considered "white noise". It is believed that this may be similar to the auditory effect that may be perceived as a common perceptual hum called

The concept of "olfactory white" has been proven. It has been found that the more odor components two mixtures have, the more similar they will smell, even if the two mixtures have no individual components in common. Moreover, odorant mixtures having about 10 or more constituents will certainly begin to produce similar odors, regardless of which individual odorant components are included. The effect becomes more pronounced when a larger number of odorants are included, for example 20, 30 or 40 odorants. As discussed in more detail below, the effect may also be more pronounced when the odorants extend into the olfactory stimulation space.

In use, at least ten different odor components of the odor control substrate combine with unpleasant odors, such as off-flavors and malodors, caused by heating of the aerosol-forming substrate to form an olfactory white. Olfactory white formation means that the user and others in the immediate vicinity of the aerosol-generating article are unable to discern any of the particular odor components of the odor control substrate. More importantly, the user and others in the immediate vicinity of the aerosol-generating article cannot distinguish between off-flavors and malodors caused by heating of the aerosol-forming substrate. As a result, advantageously, any unpleasant odors caused by heating of the aerosol-forming substrate are not perceived.

As used herein in connection with the present invention, the term "aerosol-generating article" is used herein to mean an article in which an aerosol-forming substrate is heated to produce an inhalable aerosol and deliver it to a consumer. used for. As used herein, the term "aerosol-forming substrate" refers to a substrate that has the ability to generate an aerosol by releasing volatile compounds upon heating.

The at least ten different odor components may be any odor components. One or more of the at least 10 different odor components may include abhexone, acetophenone, ortho-acetylpyridine, strawberry aldehyde, gamma-nonalactone, isoamyl acetate, amyl butyrate, iso-pentylphenyl acetate, pentyl valerate, anisole, benzaldehyde. , isobornyl acetate, butanoic acid, butyl sulfide, caryophyllene, celeriac, chlorothymol, cinnamaldehyde, coumarin, p-cresol, p-cresyl acetate, p-cresyl isobutyrate, 4-methylanisole, cuminaldehyde, cyclohexanol, 2 , 4-trans-trans-decadienal, dibutylamine, diethyl sulfide, dimethylbenzylcarbinyl butyrate, Muguet carbinol, 2,3-dimethylpyrazine, 2,5-dimethylpyrazine, dimethyltrisulfide, diphenyloxide, ethyl butyrate, propion Ethyl acid, 2-ethylpyrazine, eucalyptol, eugenol, furfuryl mercaptan, guaiacol, heptanal, 1-heptanol, hexanal, hexanoic acid, 1-hexanol, 3-hexanol, trans-1-hexanal, 2-phenylpropionaldehyde Dimethyl acetal, hydroxycitronellal, indole, linalool, melonal, l-menthol, 2-methoxynaphthalene, methyl anthranilate, methylacetaldehyde dimethyl acetal, paramethylquinoline, methyl salicylate, S-(methylthio)butyrate, musk galaxolide, Nonyl acetate, 1-octanol, 1-octen-3-ol, pentanoic acid, 4-pentenoic acid, phenylacetic acid, phenylacetylene, phenylethanol, isophorone, alphapinene, propyl butyrate, propyl sulfide, skatole, α-terpineol, thio Glycolic acid, thiophene, thymol, ortho-tolualdehyde, toluene, gamma-undecalactone, undecylenic acid, isovaleraldehyde, iso-valeric acid, gamma-valerolactone, vanillin, acetic acid, acetaldehyde, acetoin, propan-2-one , butanal, octanal, 2-hydroxypropanoic acid, butan-2,3-dione, propan-1-ol, 2-oxopropanoic acid, methylsulfanylmethane, decanoic acid, propan-2-ol, 2-methylpropanal, Butan-2-one, methyl acetate, 2-methylpropanoic acid, methyl benzoate, ethyl benzoate, ethyl 2-hydroxypropanoate, 2-methyl-5-propan-2-ylcyclohex-1,3-diene, 1-Methyl-4-propan-2-ylbenzene, 2-phenylethyl acetate, (3S)-3,7-dimethyloct-6-en-1-ol, ethyl octoate, propan-1-thiol, ethyl formate , ethyl decanoate, heptane-2-one, methyl octoate, undecanal, ethyl acetate, 4-methylpent-3-en-2-one, butan-2-thiol, ethyl pentanoate, heptane-2-ol, propane Methyl acid, hexan-3-one, pent-1-en-3-ol, methyl butanoate, (methyldisulfanyl)methane, pentyl acetate, nonan-2-ol, decan-2-one, bis(methylsulfanyl) Methane, pentan-2-ol, hexyl hexanoate, 4-methoxybenzaldehyde, diethyl butanedioate, ethyl hexanoate, butyl acetate, 4-ethylguaiacol, (R)-(+)-beta-citronellol, limonene, laevo- It may be selected from the list consisting of beta-pinene, geraniol, thiolane, trimethylamine.

At least ten different odor components may be selected from this list. Each of at least ten different odor components may be selected from this list.

Provision of at least ten different odor components selected from this list has been found to produce an effective olfactory white.

At least ten different odor components may span the olfactory stimulation space.

The provision of at least ten different odorants spanning the olfactory stimulation space may produce a particularly effective olfactory white.

As used herein in connection with the present invention, the term "olfactory stimulation space" refers to a database in which odor components are arranged based on a number of parameters of the odor components. The olfactory stimulation space may be an "odor perception space." In this case, the odor component is assigned multiple perceptual descriptors characterizing the odor. An example of a suitable "odor perceptual space" is the "Atlas of Odor Character Profiles" by Andrew Dravnieks, which assigns quantitative values to each of 146 perceptual descriptors for each of 114 odor components. assign. The olfactory stimulation space may be an "odor physiochemical space". In this case, the odor components are assigned physicochemical or molecular descriptors based on their chemical composition. Physicochemical or molecular descriptors may be assigned to odor components using software. For example, physicochemical or molecular descriptors are described by Talete S. r. l. odor components may be assigned using the Dragon software. In this way, each of the 1438 physicochemical properties of each of the 1492 odorant components is assigned a qualitative value.

By combining both perceptual descriptors and physicochemical properties, each odor component may be represented by a vector whose coordinates can be divided into 146 perceptual properties or 1438 physical properties of any given odor component. Describe chemical properties. By plotting multiple coordinates for different odor components, an "odor physiochemical space" may be constructed.

This "odor physiochemical space" may be used to calculate Euclidean distances between different odor components. Furthermore, in a mixture of many different odorants, it is also possible to calculate the minimum Euclidean distance between any given odorant and the nearest other odorant in the mixture. For example, if the coordinates of the odor components in the mixture in the virtual odor physiochemical space are ([4, -6, 8], [3, -3, 10], [-4, 0, 3]), The distance of odor x with coordinates [-2,1,1] to the mixture will be 3, because this distance is at the distance to the nearest point [-4,0,3] This is because there is.

In this way, the average minimum Euclidean distance T(G) between any given odor component and the closest other odor component in the mixture of odor components may be calculated. Using an iterative process, the average minimum Euclidean distance may be maximized.

Each of the at least ten different odor components may be provided with substantially equal perceived intensity.

It has been found that the provision of at least ten different odor components provided at substantially equal perceived intensities produces a particularly effective olfactory white. This is because no single odor component stands out from the mixture and therefore no single odor is distinguishable.

To provide odorants with substantially equal perceived intensities, all odorants used in the mixture are perceived approximately equally, either mineral oil, 1,2-propanediol, or deionized distilled water. diluted to the point of strength. At this point, the intensity of each diluted odor component is assessed by a group of naïve subjects. Any odor components that are more than two standard deviations away from the average intensity of the series are further diluted. This process is repeated until there are no outliers.

The odor control substrate may include at least about 10 different odor components. For example, the odor control substrate may include at least about 15 different odor components, at least about 20 different odor components, at least about 25 different odor components, or at least about 30 different odor components. The odor control substrate may include at least 20, preferably at least 30 different odor components.

The odor control substrate may contain more than 30 different odor components. For example, the odor control substrate can contain at least about 35 different odorants, at least about 40 different odorants, at least about 45 different odorants, at least about 50 different odorants, at least about 55 different odorants. component, or at least about 60 different odorant components.

It has been found that odor control substrates containing a greater number of odor components may provide more effective olfactory whiteness.

The odor control substrate may be a solid odor control substrate. The odor control substrate may be a liquid odor control substrate.

The odor control substrate may be applied to at least one other component of the aerosol generating article. The odor control substrate may be applied to at least one other component of the aerosol generating article by any method. If the odor control substrate is a liquid, the odor control substrate may be applied to at least one other component of the aerosol generating article by spraying as a solution, e.g., as an aqueous solution, as part of a glue or adhesive, or It may be contained within at least one capsule or bead.

For example, the odor control substrate may be encapsulated within a frangible capsule that is embedded within another component of the aerosol generating article. For example, the capsule may be embedded within a filter element or within a mouthpiece element. The capsule may be provided within a cavity of another component of the aerosol-generating article. The frangible capsule may be configured to break or rupture during use of the aerosol generating article to release the liquid odor control substrate. The frangible capsule may be configured to break or rupture in response to pressure from a user.

As provided in more detail below, the odor control substrate may include a solid support material impregnated with an odor component.

If the odor control substrate is a solid odor control substrate or a solid support material impregnated with an odor component, the solid substrate or support material may be embedded within another component of the aerosol generating article. For example, a solid substrate or support material may be embedded within a filter element or within a mouthpiece element. A solid substrate or support material may be provided within a cavity within another component of the aerosol generating article.

The odor control substrate may be provided anywhere within the aerosol generating article. For example, an odor control substrate may be provided on one or more of a mouthpiece element, a filter element, or an aerosol-forming substrate.

The aerosol generating article may further include a wrapper. The wrapper may surround at least a portion of the aerosol-forming substrate. The wrapper may be at least one of wrapping paper, tipping paper, or plug wrap. An odor control substrate may be provided on the wrapper.

Providing an odor control substrate on the wrapper may mean that the odor control substrate is located near the user's nose during use. This may advantageously maximize the effectiveness of the odor control substrate, particularly for reducing or preventing the perception of unpleasant odors by users of the aerosol generating article. Additionally, providing the odor control substrate on the wrapper rather than, for example, on a component embedded within the aerosol-generating article may keep the odor control substrate separate from the mainstream aerosol generated by the aerosol-forming substrate. This may advantageously prevent the odor control substrate from interfering with the flavor of the aerosol generated by the aerosol forming substrate.

An odor control substrate may be provided on the inner surface of the wrapper. Preferably, an odor control substrate is provided on the outer surface of the wrapper.

The odor control substrate may be provided at least about 8 millimeters, at least about 10 millimeters, or at least about 12 millimeters from the downstream end of the aerosol generating article. This may advantageously prevent the odor control substrate from being covered by the user's lips during use.

The wrapper surrounding at least a portion of the aerosol-forming substrate may be a paper wrapper or a non-paper wrapper. Suitable paper wrappers for use in certain embodiments of the invention are known in the art and include, but are not limited to, cigarette paper and filter plug wrap. Suitable non-paper wrappers for use in certain embodiments of the invention are known in the art and include, but are not limited to, sheets of homogenized tobacco material. In certain preferred embodiments, the wrapper may be formed from a laminated material that includes multiple layers. Preferably, the wrapper is formed from an aluminum co-laminated sheet. The use of a co-laminated sheet containing aluminum advantageously prevents combustion of the aerosol-forming substrate when it should be ignited rather than being heated in the intended manner.

The wrapper may be a thermally conductive, non-flammable wrapper.

Providing a thermally conductive, non-flammable wrapper may advantageously allow heat from the heater to be transferred to the aerosol forming substrate by conduction. This may advantageously help achieve a sufficiently high conductive heat transfer from the heater to the aerosol-forming substrate to produce an acceptable aerosol.

Suitable thermally conductive nonflammable wrappers include metal foils (e.g., aluminum foil wrappers, steel foil wrappers, iron foil wrappers, copper foil wrappers, etc.), alloy foil wrappers, graphite foil wrappers, and certain ceramic fiber wrappers. These include, but are not limited to:

The wrapper may have any thickness. The wrapper may have a thickness of about 30 micrometers to about 200 micrometers. The wrapper may have a thickness of at least about 30 micrometers, at least about 50 micrometers, or at least about 75 micrometers.

The wrapper may have a thickness of about 250 micrometers or less, about 200 micrometers or less, or 150 micrometers or less.

For example, the wrapper may have a thickness of about 50 micrometers to about 200 micrometers, or about 75 micrometers to about 150 micrometers. The wrapper coating may have a thickness of about 150 micrometers.

As used herein in connection with the present invention, the terms "upstream" and "forward" and "downstream" and "aft" refer to the direction in which air flows through an aerosol-generating article during use of the aerosol-generating article; Used to describe the relative position of components or portions of components of an aerosol-generating article. Aerosol generating articles according to the invention include a proximal end through which the aerosol exits during use. The proximal end of the aerosol generating article may also be referred to as the mouth end or downstream end. The oral end is downstream of the distal end. The distal end of the aerosol generating article may also be referred to as the upstream end. Components or portions of components of an aerosol-generating article may be upstream or downstream of each other based on their relative positions between the proximal end of the aerosol-generating article and the distal end of the aerosol-generating article. may be written. The forward portion of a component or portion of a component of an aerosol-generating article is the portion that is at the end closest to the upstream end of the aerosol-generating article. The rear of a component or portion of a component of an aerosol-generating article is that portion of the aerosol-generating article that is at the end closest to the downstream end.

The odor control substrate may be provided as a band surrounding a portion of the wrapper.

Providing a band surrounding the wrapper may advantageously simplify manufacturing of the aerosol generating article.

The odor control substrate may include a solid support material impregnated with an odor component.

Providing an odor control substrate that includes a solid support material may advantageously provide a simple and straightforward way to add odor components to an aerosol generating article.

Odor components may be adsorbed or absorbed onto the solid support material.

The solid support material may include a porous solid support material. This may advantageously allow greater amounts of odor components to be absorbed into the solid support material.

The solid support material may include strips of paper.

A strip of paper may surround a portion of the wrapper. The paper strips may be attached to the wrapper by adhesive.

The paper strips may have a basis weight of about 20 gsm to about 120 gsm. For example, the paper strip may have a basis weight of about 40 gsm to about 100 gsm, or about 60 gsm to about 90 gsm.

The upstream end of the paper strip may be at least 10 millimeters from the upstream end of the aerosol generating article.

Ensuring that the paper strip is at least 10 millimeters from the upstream end of the aerosol-generating article is advantageous when the paper strip is at least 10 millimeters from the upstream end of the aerosol-generating article when the article is inserted into the device. It may be ensured that it is located on the outside. If the paper strip is placed inside the aerosol generator during use, the odor components will not be able to diffuse effectively into the user's nose.

Ensuring that the paper strip is at least 10 mm from the upstream end of the aerosol-generating article may advantageously ensure that the odor control substrate is placed close to the user's nose. Yes, this may help odor control substrates reduce or prevent unpleasant odors.

In embodiments where the odor control substrate includes a band, but does not include a strip of paper, the upstream end of the band may be at least 10 millimeters from the upstream end of the aerosol-generating article.

The upstream end of the paper strip may be at least 15 millimeters, or at least 17 millimeters from the upstream end of the aerosol generating article.

The downstream end of the paper strip may be at least 8 millimeters from the downstream end of the aerosol generating article.

Ensuring that the paper strip is at least 8 mm from the downstream end of the aerosol-generating article ensures that the paper strip is not covered by the user's lips when the aerosol-generating article is in use. It may be. This is because the odor control substrate is not intended to be consumed orally, and covering the paper strip with the user's lips may prevent odor components from reaching the user's nose. Therefore, it may be advantageous.

In embodiments where the odor control substrate includes a band, but does not include a strip of paper, the downstream end of the band may be at least 8 millimeters from the downstream end of the aerosol-generating article.

The downstream end of the paper strip may be at least 10 millimeters, or at least 12 millimeters from the downstream end of the aerosol-generating article.

The paper strip may have a width of about 1 millimeter to about 10 millimeters.

For example, the paper strip may have a width of about 1 millimeter to about 5 millimeters.

The odor control substrate includes a portion of the wrapper into which odor components have been adsorbed or absorbed.

If the odor control substrate includes a portion of the wrapper on which the odor component has been adsorbed or absorbed, there may be no need for a separate paper strip. This may advantageously simplify manufacturing and may also allow the article to maintain a constant diameter along its length.

The portion of the wrapper in which the odor component has been adsorbed or absorbed may be indicated by an indicia. This may help prevent the user from covering the odor control substrate during use.

The odor control substrate may include at least 0.01 grams of odor component.

In other words, the total mass of the at least 10 different odor components may be at least 0.01 grams.

Providing at least 0.01 grams of odor component may advantageously reduce or prevent unpleasant odors generated by the aerosol-forming substrate.

For example, the odor control substrate may include at least 0.05 grams, at least 0.1 grams, at least 0.15 grams, at least 0.25 grams, at least 0.5 grams, or at least 1.0 grams of odor control substrate. good.

The aerosol-generating article may further include a downstream segment located downstream of the aerosol-forming substrate, and the odor control substrate overlies the downstream segment.

Providing the odor control substrate around the downstream element rather than around the aerosol forming substrate may keep the odor control substrate separate from the aerosol forming substrate. This may advantageously help prevent odor components from mixing with the mainstream aerosol. Providing an odor control substrate around the downstream segment may also prevent the odor control substrate from heating during use of the aerosol generating article.

The downstream segment may be any downstream segment. For example, a downstream segment may include a single component. A downstream segment may include multiple components. The downstream segment may include one or more of a cooling element, a filter element, or a spacer element.

The downstream segment may include a mouthpiece element. The mouthpiece element may be located at the mouth end or downstream end of the aerosol generating article.

The downstream segment may include a segment of filtration material. For example, the mouthpiece element may include one or more segments of filtration material.

For example, the mouthpiece element may include one or more segments of filtration material. The filtration material may include fibrous filtration material. Suitable fibrous filter materials will be well known to those skilled in the art. It is particularly preferred that the at least one mouthpiece filter segment comprises a cellulose acetate filter segment formed from cellulose acetate tow.

The mouthpiece element may include a single mouthpiece filter segment. The mouthpiece element may include two or more mouthpiece filter segments axially aligned in abutting end-to-end relationship with each other.

The downstream segment may include a mouth end cavity at the downstream end downstream of the mouthpiece element as described above. The oral end cavity may be defined by a hollow tubular element provided at the downstream end of the mouthpiece. The oral end cavity may be defined by an outer wrapper of the mouthpiece element, the outer wrapper extending in a downstream direction from the mouthpiece element.

The mouthpiece element may optionally include a flavoring agent, which may be provided in any suitable form. For example, the mouthpiece element may include one or more capsules, beads, or granules of flavorant, or one or more threads or filaments loaded with flavor.

The downstream segment of the aerosol-generating article may include a support element located immediately downstream of the aerosol-forming substrate. The mouthpiece segment may be located downstream of the support element. The downstream segment may include an aerosol cooling element located immediately downstream of the support element. The mouthpiece element may be located downstream of both the support element and the aerosol cooling element. The mouthpiece element may be located immediately downstream of the aerosol cooling element. The mouthpiece element may abut the downstream end of the aerosol cooling element.

The mouthpiece element may have low particulate filtration efficiency.

The mouthpiece element may be surrounded by plug wrap. The mouthpiece element may not be vented to prevent air from entering the aerosol-generating article along the mouthpiece element.

Aerosol-generating articles according to the present invention include an aerosol-forming substrate. The aerosol-forming substrate may be a solid aerosol-forming substrate. The aerosol-forming substrate may be a liquid aerosol-forming substrate. Aerosol-forming substrates may include both solid and liquid components. The aerosol-forming substrate may include a tobacco-containing material containing volatile tobacco flavor compounds that are released from the substrate upon heating. The aerosol-forming substrate may include non-tobacco materials. The aerosol-forming substrate may further include one or more aerosol formers.

Suitable aerosol formers include, for example, polyhydric alcohols (e.g., triethylene glycol, 1,3-butanediol, propylene glycol, glycerin, etc.), esters of polyhydric alcohols (e.g., glycerol mono-, di-, or triacetate, etc.). ), aliphatic esters of mono-, di-, or polycarboxylic acids (eg, dimethyl dodecanedioate, dimethyl tetradecanedioate, etc.), and combinations thereof.

The aerosol former may include one or more of glycerin and propylene glycol. The aerosol former may consist of glycerin, or propylene glycol, or a combination of glycerin and propylene glycol.

The aerosol-forming substrate comprises about 5 weight percent to about 30 weight percent on a dry weight basis (such as about 10 weight percent to about 25 weight percent on a dry weight basis, or about 15 weight percent to about 20 weight percent on a dry weight basis). It may also have an aerosol former content.

For example, if the substrate is intended for use in an aerosol-generating article for an electrically operated aerosol-generating system having a heating element, it preferably contains from about 5 weight percent to about 30 weight percent aerosol on a dry weight basis. It may also include a former content. When the substrate is intended for use in an aerosol-generating article for an electrically operated aerosol-generating system having a heating element, it is preferred that the aerosol former is glycerol.

In other embodiments, the aerosol-forming substrate may have an aerosol former content of about 1 weight percent to about 5 weight percent on a dry weight basis.

In other embodiments, the aerosol-forming substrate may have an aerosol former content of about 30 weight percent to about 45 weight percent. This relatively high level of aerosol former is particularly suitable for aerosol generating substrates that are intended to be heated at temperatures below 275 degrees Celsius. In such embodiments, the aerosol-generating substrate further comprises from about 2 weight percent to about 10 weight percent cellulose ether on a dry weight basis and from about 5 weight percent to about 50 weight percent additional cellulose on a dry weight basis. It is preferable. The use of a combination of cellulose ethers and additional cellulose has been found to provide particularly effective aerosol delivery when used in an aerosol-forming substrate having an aerosol former content of 30 weight percent to 45 weight percent. Ta.

As presented above, it has been found that the process of heating rather than burning an aerosol-forming substrate can lead to the generation of undesirable and unpleasant odors. Without wishing to be bound by theory, it is believed that the generation of unpleasant odors may be caused in part by aerosol formers that assist in the generation of aerosols. The amount of aerosol former in an aerosol-generating article in which the aerosol-forming substrate is heated rather than combusted is typically higher than the amount in conventional cigarettes. As a result, the provision of an odor suppressing substrate in an aerosol generating article containing this amount of aerosol former may be particularly advantageous for reducing or preventing the perception of unpleasant odors.

The aerosol-forming substrate may be a rod containing tobacco-containing material.

When the aerosol-forming substrate is a solid aerosol-forming substrate, the solid aerosol-forming substrate is one of the following: herbal leaves, tobacco leaves, tobacco stem fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco, expanded tobacco. For example, it may contain one or more of powders, granules, pellets, pieces, spaghetti-like strands, strips, or sheets containing one or more of the following. The solid aerosol-forming substrate may be in bulk form or may be provided in a suitable container or cartridge. For example, the aerosol-forming material of a solid aerosol-forming substrate may be contained within a paper or other wrapper and in the form of a plug. When the aerosol-forming substrate is in the form of a plug, the entire plug, including any wrapper, is considered to be an aerosol-forming substrate.

The solid aerosol-forming substrate may contain additional tobacco or non-tobacco volatile flavor compounds that are released upon heating of the solid aerosol-forming substrate. The solid aerosol-forming substrate may also contain capsules containing, for example, additional tobacco or non-tobacco volatile flavor compounds, and such capsules may melt during heating of the solid aerosol-forming substrate.

The solid aerosol-forming substrate may be provided on or embedded within a thermally stable carrier. The carrier may take the form of a powder, granules, pellets, fragments, spaghetti-like strands, strips, or sheets. The solid aerosol-forming substrate may be deposited on the surface of the carrier, for example in the form of a sheet, foam, gel, or slurry. A solid aerosol-forming substrate may be deposited on the entire surface of the carrier. The solid aerosol-forming substrate may be deposited in a pattern to provide non-uniform flavor delivery during use.

The aerosol-forming substrate may be in the form of a plug or segment containing a material capable of emitting volatile compounds in response to heating surrounded by a paper or other wrapper. When the aerosol-forming substrate is in the form of such a plug or segment, the entire plug or segment, including any wrappers, is considered to be an aerosol-forming substrate.

Preferably, the aerosol-forming substrate has a length of about 5 millimeters to about 20 millimeters. In certain embodiments, the aerosol-forming substrate may have a length of about 6 millimeters to about 15 millimeters, or about 7 millimeters to about 12 millimeters.

The aerosol-forming substrate may be wrapped in plug wrap and provided with a plug of tobacco-based material. In a preferred embodiment, the aerosol-forming substrate comprises a plug of homogenized tobacco-based material wrapped in plug wrap.

The aerosol generating article may further include a susceptor element within the aerosol forming substrate. In some embodiments, the susceptor element may be an elongated susceptor element. In a preferred embodiment, the susceptor element extends longitudinally within the aerosol-forming substrate.

The aerosol-generating article according to the invention may further comprise a transition element or a spacer element downstream of the aerosol-forming substrate. Such elements may take the form of hollow tubes located downstream of the aerosol-forming substrate.

The hollow tube may extend from the downstream end of the aerosol-forming substrate to the downstream end of the aerosol-generating article.

The transition element may abut one or both of the aerosol-forming substrate and the mouthpiece. The transition element may be spaced apart from one or both of the aerosol-forming substrate and the mouthpiece.

The inclusion of a transition element advantageously allows the aerosol to cool. The inclusion of a transition element also advantageously reduces the overall length of the aerosol-generating article to a desired value (e.g., a length similar to the length of a conventional cigarette) by appropriate selection of the length of the transition element. ).

The transmission element may have a length of about 7 mm to about 50 mm, such as about 10 mm to about 45 mm, or about 15 mm to about 30 mm. The transition element may have other lengths depending on the desired overall length of the aerosol-generating article and the presence and length of other components within the aerosol-generating article.

Preferably, the transition element comprises a tubular hollow body open at at least one end. In such embodiments, in use, air drawn into the aerosol-generating article passes through the aerosol-generating article downstream from the aerosol-forming substrate to the distal end of the aerosol-generating article. It passes through two tubular hollow bodies.

Aerosol-generating articles according to the invention may include an aerosol cooling element or heat exchanger downstream of the aerosol-forming substrate. The aerosol cooling element may include a plurality of longitudinally extending channels.

An aerosol-generating article according to the invention may comprise a plurality of elements assembled in the form of a rod.

The aerosol generating article may further include an upstream element upstream of the aerosol forming substrate. Providing an upstream element may advantageously protect the aerosol-forming substrate and prevent a user from coming into direct contact with the aerosol-forming substrate. The upstream element may include an annular plug containing fibrous filtration material.

The aerosol generating article may be substantially cylindrical in shape. The aerosol generating article may be substantially elongated. The aerosol-forming substrate may be substantially cylindrical in shape. The aerosol-forming substrate may be substantially elongated.

For example, the aerosol generation system may be configured to heat the aerosol-forming substrate to a temperature of about 150 degrees Celsius to about 450 degrees Celsius, or about 200 degrees Celsius to about 400 degrees Celsius.

As presented above, it has been found that the process of heating rather than burning an aerosol-forming substrate can lead to the generation of undesirable and unpleasant odors. In aerosol-generating articles where the aerosol-forming substrate is heated rather than combusted to generate the aerosol, the aerosol-forming substrate is typically heated to a temperature well below the combustion temperature of the aerosol-forming substrate. As a result, providing an odor control substrate in an aerosol-generating article for use in a system configured to heat the aerosol-generating article to a temperature of about 100 degrees Celsius to about 500 degrees Celsius reduces or reduces the perception of unpleasant odors. It may be particularly advantageous to prevent

Examples will now be further described with reference to the following figures.

FIG. 1 shows a schematic longitudinal cross-sectional view of an aerosol-generating article according to the invention. FIG. 2 shows a schematic longitudinal cross-sectional view of an aerosol generation system comprising an aerosol generation article according to the invention in cooperation with an aerosol generation device.

The aerosol-generating article 10 shown in FIG. 1 includes an aerosol-forming substrate 12 and a downstream section 14 at a location downstream of the aerosol-forming substrate 12. The aerosol-generating article 10 shown in FIG. Aerosol generating article 10 further includes an upstream element 16 at a location upstream of aerosol forming substrate 12 . Thus, the aerosol generating article 10 extends from an upstream or distal end 18 to a downstream or oral end 20.

Aerosol generating article 10 has an overall length of approximately 30 millimeters.

Downstream section 14 includes a support element 22 located immediately downstream of aerosol-forming substrate 12 , with support element 22 in longitudinal alignment with aerosol-forming substrate 12 . In the embodiment of FIG. 1, the upstream end of the support element 18 abuts the downstream end of the aerosol-forming substrate 12. In addition, the downstream section 14 includes an aerosol cooling element 24 located immediately downstream of the support element 22 and in longitudinal alignment with the rod 12 and the support element 22. In the embodiment of FIG. 1, the upstream end of the aerosol cooling element 24 abuts the downstream end of the support element 22.

As will become apparent from the description below, support element 22 and aerosol cooling element 24 together define an intermediate hollow section 50 of aerosol generating article 10. Overall, the intermediate hollow section 50 does not substantially contribute to the overall RTD of the aerosol generating article.

Support element 22 comprises a first hollow tubular segment 26 . The first hollow tubular segment 26 is provided in the form of a hollow cylindrical tube made of cellulose acetate. First hollow tubular segment 26 defines an interior cavity 28 extending from an upstream end 30 of the first hollow tubular segment all the way to a downstream end 32 of first hollow tubular segment 26 . Internal cavity 28 is substantially empty, thereby allowing substantially unrestricted airflow therealong.

Aerosol cooling element 24 includes a second hollow tubular segment 34 . The second hollow tubular segment 34 is provided in the form of a hollow cylindrical tube made of cellulose acetate. The second hollow tubular segment 34 defines an interior cavity 36 that extends from an upstream end 38 of the second hollow tubular segment all the way to a downstream end 40 of the second hollow tubular segment 34 . Internal cavity 36 is substantially empty, thereby allowing substantially unrestricted airflow therealong. Second hollow tubular segment 28 and, as a result, aerosol cooling element 24 do not substantially contribute to the overall RTD of aerosol generating article 10.

Aerosol generating article 10 includes a ventilation zone 60 provided at a location along second hollow tubular segment 34 . More particularly, a ventilation zone is provided approximately 2 millimeters from the upstream end of the second hollow tubular segment 34. The aeration level of the aerosol generating article 10 is approximately 25 percent.

In the embodiment of FIG. 1, downstream section 14 further comprises an optional mouthpiece element 42 at a location downstream of intermediate hollow section 50. In the embodiment of FIG. More particularly, mouthpiece element 42 is positioned immediately downstream of aerosol cooling element 24. As shown in the drawing of FIG. 1, the upstream end of the mouthpiece element 42 abuts the downstream end 40 of the aerosol cooling element 18.

Mouthpiece element 42 is provided in the form of a cylindrical plug of low density cellulose acetate.

Aerosol generating article 10 further includes an elongate susceptor element 44 within aerosol forming substrate 12 . More particularly, susceptor element 44 is disposed substantially longitudinally within aerosol-forming substrate 12, such as substantially parallel to the longitudinal axis of rod 12. As shown in the drawing of FIG. 1, the susceptor element 44 is positioned radially centrally within the aerosol-forming substrate 12 and effectively extends along the longitudinal axis of the aerosol-forming substrate 12.

Susceptor element 44 extends from the upstream end of aerosol-forming substrate 12 all the way to the downstream end. In fact, the susceptor element 44 has substantially the same length as the aerosol-forming substrate 12 of the aerosol-forming substrate.

The upstream element 46 is provided in the form of a cylindrical plug of cellulose acetate surrounded by a rigid wrapper.

Aerosol generating article 10 further includes an odor control substrate 60. Odor control substrate 10 is in the form of a band formed by a strip of paper material surrounding mouthpiece element 42 . Paper strips are attached to the wrapper using glue. The paper strip is positioned about 12 millimeters downstream of the downstream end 20 of the aerosol generating article 10. The paper strips are impregnated with at least 10 different odorants. Details of suitable combinations of odorant components are provided below.

As shown in FIG. 2, the aerosol generating article 10 is inserted into an aerosol generating device 65 during use. The induction coil in the aerosol generator inductively heats the susceptor 44 in the aerosol generating article 10. The heating susceptor 44 heats the aerosol forming substrate 12 . Aerosol-forming substrate 12 generates steam, which cools within hollow section 50 and nucleates into an aerosol. The pressure drop at the downstream end 20 of the aerosol-generating article 10 draws air into the aerosol-generating article 10 through the air inlet 60. Air drawn through air inlet 60 entrains vapor from aerosol-forming substrate 12 . This air entrained with vapor then passes through the mouthpiece 42 and exits the downstream end of the aerosol generating article 10.

At the same time, the odor control substrate 60 disposed on the outside of the aerosol generating article 10 releases odor control molecules from at least ten different odor components. These molecules released from at least 10 different odor controls create an olfactory white that prevents the user from discerning unpleasant odors generated by the aerosol-forming substrate.

Examples of suitable combinations of odorant components that have been found to produce olfactory whites are presented below. Specific combinations of odor components are listed as "Ex-1" through "Ex-34" and are presented in Tables 1 through 4. The odor components in each example are identified by the chemical's PubMed CID number. The name of each odor component corresponding to each CID number is presented in Table 5 below.

Table 1 shows three examples, Ex-1, Ex-2, Ex-3. Ex-1 and Ex-2 each contain 60 different odor components. There is no overlap between Ex-1 and Ex-2. Example Ex-3 contains 30 different odor components.

Table 2 shows five examples, Ex-4 to Ex-8. Each of Ex-4 to Ex-8 contains 30 different odorants, spanning the physicochemical space.

Table 3 shows 12 examples, Ex-9 to Ex-20. Ex-9, Ex-10, Ex-15, and Ex-16 each contain 10 different odor components. Ex-11, Ex-12, Ex-17, and Ex-18 each contain 20 different odor components. Ex-13, Ex-14, Ex-19, and Ex-20 each contain 30 different odor components. The specific selection of odor components for Examples Ex-9 to Ex-20 was selected based on the odor perception space.

Table 4 shows 14 examples, Ex-21 to Ex-34. Ex-21, Ex-22, Ex-27, and Ex-28 each contain 10 different odor components. Ex-29 and Ex-30 each contain 15 different odor components. Ex-23, Ex-24, Ex-31, and Ex-32 each contain 20 different odor components. Ex-25, Ex-26, Ex-33, and Ex-34 each contain 30 different odor components. The specific selection of odor components for Examples Ex-21 to Ex-34 was selected based on the odor physicochemical space.
