Description

The present invention relates to aerosol generation, particularly, but not limited to, articles for use in non-combustion aerosol delivery systems and non-combustion aerosol delivery systems.

Smoking products such as cigarettes and cigars burn tobacco and produce smoke when used. Alternatives to these types of articles release compounds without combustion.

BACKGROUND OF THE INVENTION Devices are known that heat an aerosol-generating material to volatilize at least one component of the aerosol-generating material without burning or combusting the aerosol-generating material, typically to form an inhalable aerosol. Such devices are sometimes described as "non-combustion heating" devices or "tobacco heating products" (THPs) or "tobacco heating devices" or the like. A variety of different structures are known for volatilizing at least one component of an aerosol generating material.

The materials may be a combination of tobacco or other non-tobacco products or blends that may or may not contain nicotine.

In a first aspect of the invention there is provided an article for use in a non-combustible aerosol delivery system, the article comprising a filter and an aerosol generator, the aerosol generator comprising an aerosol generator and an encapsulated aerosol generator. the encapsulated first aerosol modifier is released upon heating to at least a threshold release temperature, and the filter includes a member holding the second aerosol modifier. and a second aerosol modifier is selectively released from the member.

Providing an encapsulated first aerosol modifier that is releasable upon heating to a threshold temperature allows the first aerosol modifier to be released over an extended period of time. By providing a selectively releasable second aerosol modifier in the first filter portion of the article, the composition of the generated aerosol is controlled by the user. The user can select whether and when to release the second aerosol modifier.

In a second aspect of the invention there is provided a non-combustion aerosol delivery system comprising a heater and an article according to the first aspect, the heater being for heating an aerosol generating portion of the article when used to generate an aerosol. It is arranged in

The features disclosed herein for an article are expressly disclosed in combination with the system of the invention and vice versa.

Further characteristics and advantages of the invention will become apparent from the following description of some examples of the invention, given by way of example only and with reference to the accompanying drawings, in which: FIG.

FIG. 1 is a perspective view of an example article for use within a non-combustion aerosol delivery system. FIG. 1 is a perspective view of an example of a non-combustion aerosol supply system. Figure 2 is a graph showing the results of the study described in the Examples below. Figure 2 is a graph showing the results of the study described in the Examples below.

Aerosol generation systems according to some examples of the invention may also be referred to herein as non-combustion heating devices, tobacco heating products, or tobacco heating devices.

As noted above, the present invention provides an article for use in a non-combustion aerosol delivery system, the article including a filter and an aerosol generator;
The aerosol generating section includes an aerosol generating material and an encapsulated first aerosol modifier, the encapsulated first aerosol modifier is released by heating to at least a threshold release temperature, and the filter is , a member retaining a second aerosol modifier, the second aerosol modifier being selectively released from the member.

Separately, such articles may also be referred to herein as aerosol-generating articles.

As used herein, the term "aerosol modifier" refers to an aerosol modifier that is capable of being aerosolized and that can be combined with an aerosol generated by heating an aerosol generating material to modify how the aerosol is perceived by the user. Any chemical compound that changes In some embodiments, the aerosol modifier may include one or more of an aerosol former, a flavoring agent, a fragrance, and an active ingredient. In some embodiments, the aerosol modifier includes one or more flavoring agents, preferably menthol. In some cases the aerosol modifier consists essentially of or consists of menthol.

Optionally the first and/or second aerosol modifier comprises or consists of a flavoring agent, preferably menthol. In some cases the first and second aerosol modifiers are the same. In some cases the first and/or second aerosol modifiers are different.

The first aerosol modifier is encapsulated and the aerosol modifier is released by heating the encapsulated modifier to at least a threshold release temperature. The encapsulated first aerosol modifier is released from its capsule at a temperature that is lower than or equal to the temperature that the encapsulated modifier reaches in situ within the article during use.

In some cases the threshold release temperature is at least 50°C, sometimes at least 100°C, sometimes at least 150°C, and sometimes less than about 300°C, about 270°C or about 250°C. Encapsulation can be used to prevent unintentional volatilization of the aerosol modifier, to deliver the aerosol modifier over an extended period of time, and to prevent migration of the aerosol modifier within the aerosol generating material prior to use. .

The first aerosol modifier may be encapsulated in an encapsulant. In some cases, the encapsulating material is a polysaccharide material such as alginates, carrageenan or pectin materials, cellulosic materials, gelatin, gums, protein materials, polyol matrix materials, amorphous solids, gels, waxes, polyurethanes, ethylene vinyl acetate polymers. At least one of hydrolysates, polyesters, polycarbonates, polymethacrylates, polyglycols, polyethylene, polystyrene, polypropylene, polyvinyl chloride or mixtures thereof or mixtures of all these.

Temperature-dependent release may optionally be achieved by the use of an encapsulant that melts, decomposes, reacts, disintegrates, swells or deforms to release the flavoring agent at the release temperature. Alternatively, heating may inflate the encapsulated aerosol modifier and rupture the encapsulating material.

The encapsulated first aerosol modifier may be provided in the form of capsules that are powders, granules or beads. Optionally these capsules may be supported on a substrate. The optionally encapsulated first aerosol modifier may be provided in the form of an amorphous solid that encapsulates the aerosol modifier. The amorphous solid may include a polysaccharide matrix. Amorphous solids may be provided as thin films. This thin film may be provided, for example, in chopped or sheet form. The optionally encapsulated first aerosol modifier may be included in a mixture of these forms, such as a combination of a capsule and an encapsulating membrane.

In some embodiments, the amorphous solid includes 1 to 60 wt% gelling agent, 0.1 to 50 wt% aerosol former, and 0.1 to 80 wt% flavoring agent, the weight of which is dry weight. Calculated on a standard basis.

In some other embodiments, the amorphous solid includes 1 to 50 wt% gelling agent, 0.1 to 50 wt% aerosol forming agent, and 30 to 60 wt% flavoring agent, the weight of which is dry weight. Calculated on a standard basis.

(i.e., the gelling agent and filler together account for about 10-60 wt% of the amorphous solids), and optionally the active agent and/or flavoring agent in an amount up to about 20 wt% of the amorphous solids. (i.e. the amorphous solid contains ≦20 wt% active material).

Amorphous solids may be formed from dry gels. It has been found that using the above composition ratios stabilizes the flavor compounds within the gel matrix when the gel hardens, allowing for more flavor input in non-gel compositions. Flavors (eg, menthol) are stabilized at high concentrations and provide good shelf life.

In some cases, the amorphous solid has a wall thickness of about 0.015 mm to about 1.5 mm. Suitably the thickness may be from about 0.05 mm, 0.1 mm or 0.15 mm to about 0.5 mm, 0.3 mm or 1 mm. The inventors have found that a material thickness of 0.2 mm is particularly suitable in some embodiments. Amorphous solids may include more than one layer, and the thicknesses mentioned herein refer to the total thickness of these layers.

If the amorphous solid is too thick, heating efficiency will be compromised. This has a negative impact on power consumption during use. Conversely, if the amorphous solid is too thin, it will be difficult to manufacture and handle, and very thin materials will be difficult to cast and fragile.

Preferably, the amorphous solid is from about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, 25 wt%, 30 wt% or 35 wt% to about 60 wt%, 55 wt%, 50 wt%, 45 wt%, 40 wt% or It may contain 35 wt% gelling agent (all calculated on a dry weight basis).

In some embodiments, the amorphous solid includes alginate and pectin, and the ratio of alginate to pectin is from 1:1 to 10:1. The ratio of alginate to pectin is usually >1:1, ie, alginate is present in an amount greater than the amount of pectin. In some examples, the ratio of alginate to pectin is about 2:1 to 8:1 or about 3:1 to 6:1 or about 4:1.

In some embodiments, the amorphous solid includes filler in an amount of 1-30 wt%, such as 5-25 wt% or 10-20 wt% of the amorphous solid. In some examples, the amorphous solid includes filler in an amount greater than 1 wt%, 5 wt%, or 8 wt% of the amorphous solid. In some examples, the amorphous solid includes filler in an amount less than 40 wt%, 30 wt%, 20 wt%, 15 wt%, 12 wt%, 10 wt%, 5 wt%, or 1 wt% of the amorphous solid. In other instances, the amorphous solid is free of fillers.

In some examples, the amorphous solid is about 10 wt%, 20 wt%, 25 wt%, 30 wt%, 35 wt%, 40 wt%, 45 wt%, 50 wt%, 55 wt% in the combined amount of gelling agent and filler. or about 60 wt%. In some examples, the amount of gelling agent and filler combined is no more than 85 wt%, 80 wt%, 75 wt%, 70 wt%, 65 wt%, or 60 wt% of the amorphous solids. In some examples, the amorphous solid comprises a gelling agent and filler in an amount of about 20-60 wt%, 25-55 wt%, 30-50 wt%, or 35-45 wt% of the amorphous solid.

In some examples that include fillers, the fillers may be fibrous. For example, the filler may be a fibrous filler such as wood pulp, hemp fiber, cellulose or cellulose derivatives. Without wishing to be bound by any theory, it has been determined that the inclusion of fibrous fillers in amorphous solids increases the tensile strength of the material.

In some instances, the amorphous solid does not include tobacco fiber. In certain instances, the amorphous solid does not include fibrous material.

In some embodiments, the amorphous solid is from about 0.1 wt%, 0.5 wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt% or 10 wt% to about 80 wt%, 50 wt%, 45 wt%, 40 wt% , 35 wt%, 30 wt% or 25 wt% of aerosol former (all calculated on a dry weight basis). For example, the amorphous solid may include 0.5-40 wt%, 3-35 wt% or 10-25 wt% aerosol former.

The aerosol former may function as a plasticizer. If the content of plasticizer is too high, the amorphous solid will absorb water, resulting in a material that does not provide a suitable consumption experience when used. If the content of plasticizer is too low, the amorphous solid will become brittle and break easily.

The presence of a colorant in the amorphous solid may enhance the appearance of the amorphous solid and the aerosol generating material. A coloring agent may be added to the amorphous solid to match the color of the amorphous solid to other components of the aerosol generating material or article containing the amorphous solid.

Various colorants may be used depending on the desired color of the amorphous solid. The color of the amorphous solid may be, for example, white, green, red, purple, blue or black. Other colors are also envisioned. Natural or synthetic colorants may be used, such as natural or synthetic dyes, food grade colorants and pharmaceutical grade colorants. In certain embodiments, the colorant is a caramel that gives the amorphous solid a brown appearance. In such embodiments, the color of the amorphous solid may be similar to the color of other components in the aerosol generating material (such as tobacco material) that include the amorphous solid. In some embodiments, a colorant is added to the amorphous solid to allow visual differentiation of other components of the aerosol-generating material.

The colorant may be incorporated during the formation of the amorphous solid (e.g., during the formation of a slurry containing the material forming the amorphous solid) or applied to the amorphous solid after it has been formed. (e.g. by spraying onto amorphous solids).

Articles for use in non-combustion aerosol delivery systems may additionally include ventilation openings. These ventilation openings may be provided in the side walls of the product. Optionally, ventilation openings may be provided in the filter. These openings can allow cooling air to be drawn into the article during use, which can mix with the heated and volatilized components, thereby cooling the aerosol.

Ventilation increases the production of visible heated volatilized components from the generated product when it is heated during use. The heated and volatilized components are visualized by a cooling step of the heated and volatilized components such that supersaturation of the heated and volatilized components occurs. The heated and volatilized components then form into droplets, also known as nucleation, and the final heated and volatilized aerosol particle size is determined by the heated and volatilized components. It grows larger due to further condensation and solidification of the newly formed droplets from the heated and volatilized components.

The ratio of cooling air to the sum of heated and volatile components and cooling air, sometimes known as the ventilation rate, is at least 15%. The components heated and volatilized at a ventilation rate of 15% can be made visible in the manner described above. By making the heated and volatilized components visible, the user can confirm that the volatilized components have occurred and adds to the sensory experience of the smoking experience.

In another example, the ventilation rate is between 50% and 85% to further cool heated and volatile components. In some cases the ventilation rate may be at least 60% or 65%.

Examples of suitable ceramic materials include silicon carbide (SiC), silicon nitride (Si ₃ N ₄ ), titanium carbide, and zirconium dioxide (zirconia).

The second aerosol modifier is selectively releasable. The user activates the release mechanism to release the second aerosol modifier. For the avoidance of doubt, the second aerosol modifier is not released solely by heating the aerosol generator.

Optionally, the member holding the second aerosol modifier is a compressible member, which releases the second aerosol modifier upon application of a compressive force. For example, the member may be a compressible capsule having a release valve biased in a closed position and upon application of a compressive force to release the second aerosol modifier. open. In another example (described in more detail below), the member includes a breakable capsule that includes a second aerosol modifier. The term "breakable capsule" means a capsule whose shell can be broken by pressure to release the core, and more specifically the shell is broken by the user's finger (or ruptureable under pressure exerted by any other pressure producing means).

The optional second aerosol modifier carrying member is configured to release the aerosol modifier upon heating of the filter section. Importantly, the second aerosol modifier is not released by heating the aerosol generator alone; the user must use a boost heater that directly heats the filter section to ensure that the release temperature of the second aerosol modifier is reached. must be activated selectively. Illustratively, the filter may be exposed to temperatures in the range from 30°C to 100°C, for example from heating of the aerosol generator, and the release temperature of the second aerosol modifier is greater than 50°C and up to 120°C. Good too.

In some cases, the member includes a rupturable capsule, as described above, and the rupturable capsule includes a second aerosol modifier. The term "breakable capsule" means a capsule whose shell can be broken by pressure to release the core, and more specifically the shell is broken by the user's finger (or ruptureable under pressure exerted by any other pressure producing means).

EXAMPLE A sensory evaluation was conducted to compare the release of menthol, as an example of an aerosol modifier, from an article heated in a non-combustion aerosol delivery system. Three different articles were tested. The first article contained menthol only in the user-actuated capsule. The second article contained menthol encapsulated within an amorphous solid and contained within a rod of aerosol generating material. The third article contained menthol in a user actuated capsule and an aerosol generator rod encapsulated in an amorphous solid.

These articles were in the form of a demi-slim stick containing a rod-shaped aerosol generator, an aluminum foil wrapper, a thermal displacement chamber, a cellulose acetate plug containing one capsule, and a filter containing a tubular mouthpiece section. The capsules were standard friable core-shell capsules containing 4.5 mg of menthol.

The article containing menthol encapsulated in a rod of aerosol generating material contained 40 mg of amorphous material. The amorphous solids included:
Menthol: 40%
Glycerol: 16%
Binder (alginate/pectin mixture): 24%
Fiber (wood pulp): 20%

For testing, the articles were inserted into a commercial non-combustion aerosol delivery system, a Glo Hyper device, and heated (as per normal commercial device heating parameters). When evaluating the effectiveness of menthol capsules, the capsules were crushed before the first puff. Puffs were made every 20 seconds, and the cooling sensation and menthol taste intensity were ranked.

The results are shown in Figures 3 and 4, with Figure 3 showing the ranking of flavor perception and Figure 4 showing the ranking of cold sensation perception. It was found that the combination of an aerosol modifier encapsulated in an amorphous solid and contained in a rod of aerosol-generating material and an aerosol modifier in a user-activated capsule improved taste and cold sensation perception. These results indicate that the combination of an encapsulated aerosol modifier in the aerosol generating section of the article and a component containing the aerosol modifier in the filter can deliver a long and consistent flavor.

The above-mentioned examples are to be understood as illustrative examples of the invention. It will be understood that any feature described for any one instance may be used alone or in combination with other features described, and may be used alone or in combination with any one or more features of any other instance or any other instance. May be used in combination with any combination of the above. Furthermore, equivalents and modifications not described above may be employed without departing from the scope of the invention as defined in the appended claims.
