[0015] Embodiments of the present invention are described herein by reference only to the accompanying figures. [Brief explanation of the drawing]

[0016] [Figure 1]This is a side cross-sectional view of a first embodiment of an article having a coating containing a combustion-inhibiting salt having combustion-inhibiting properties. [Figure 2] Figure 1 is a perspective view of a non-combustible aerosol supply device for generating aerosols from the aerosol-generating material of the article shown. Detailed explanation

[0017] The present invention aims to provide an article having combustion-suppressing properties for use in a non-combustible aerosol supply system. The present invention provides an article comprising a rod containing a columnar aerosol-generating material, wherein the columnar aerosol-generating material is at least partially packaged in a package, and at least a portion of the surface of the package has a coating containing a combustion-suppressing salt.

[0018] The inventors have found that adding at least one combustion-inhibiting salt to a coating applied to the surface of a package provides combustion-inhibiting properties. The presence of the coating containing the combustion-inhibiting salt makes it even more difficult to ignite the article, thereby preventing the article from burning.

[0019] The present invention enjoys the advantage that the article can withstand higher temperatures without burning and subsequently release more volatile substances. This is desirable for the end user of a non-flammable aerosol supply system. In addition, the present invention has the added advantage of being safer because it reduces the combustion of the article if a consumer attempts to ignite it.

[0020] In addition, this packaging provides an environmentally friendly alternative to other known packaging materials that serve a role in combustion suppression. For example, aluminum is commonly used as packaging to suppress combustion in aerosol products. However, aluminum consumes a large amount of energy to manufacture and is difficult to recycle after use, making the packaging described herein a more sustainable alternative. As described herein, combustion suppression properties can be achieved using salts such as NaCl, which are sustainably available resources. In addition, the packaging may also include paper or paper-like materials, as described herein. These materials can be sustainably supplied and are biodegradable. The biodegradability of the packaging is environmentally friendly and an attractive feature for consumers.

[0021] In some embodiments, the coating on the packaging contains one or more combustion suppression salts in a total amount of at least about 3 wt%, about 3.5 wt%, about 4 wt%, about 4.5 wt%, about 5 wt%, about 5.5 wt%, about 6 wt%, about 6.5 wt%, about 7 wt%, about 7.5 wt%, about 8 wt%, about 9 wt%, about 10 wt%, about 20 wt%, about 30 wt%, about 40 wt%, about 50 wt%, about 60 wt%, about 70 wt%, and / or about 70 wt%, about 65 wt%, about 60 wt%, about 55 wt%, or about 50 wt% or less (all calculated on a dry weight basis). The amount of combustion suppression salt is selected to produce a desired combustion suppression effect.

[0022] To avoid any ambiguity, any reference to the amount of salt in the coating refers to the amount of salt added, and does not include any salt that may be present in the coating without the addition of the combustion-inhibiting salts described herein.

[0023] Combustion suppression salt The combustion-inhibiting salts used herein are compounds comprising an ionic assembly of a cation and anion. The salts used herein are salts whose anion and / or cation may be effective in inhibiting combustion. In some embodiments, the salt is an inorganic salt.

[0024] In some embodiments, the salt is a halide salt, i.e., it has a halide anion. In some embodiments, the salt is a chloride salt or a bromide salt. The presence of high concentrations of chloride or bromide has been shown to suppress combustion, as discussed further below.

[0025] In some embodiments, the salt can be an alkali metal salt, i.e., it has an alkali metal cation. In some embodiments, the salt has an alkaline earth metal cation. In some embodiments, the salt has an iron cation such as a zinc cation or a ferric or ferrous cation. In some embodiments, the salt has an ammonium cation or a phosphonium cation.

[0026] In some embodiments, the salt may be an alkali metal halide such as sodium chloride or potassium chloride. The salt may be an alkaline earth metal halide such as magnesium chloride or calcium chloride. The salt may be another metal halide such as zinc chloride or sodium bromide.

[0027] In some embodiments, the salt has a carboxylic acid anion. For example, the salt may be an alkali metal carboxylate such as potassium citrate, potassium succinate, potassium malate, potassium acetate, potassium tartrate, potassium oxalate, sodium citrate, sodium succinate, sodium acetate, or sodium malate.

[0028] In other embodiments, the salt has an anion selected from: borate anion, carbonate anion, phosphate anion, sulfate anion or sulfamate anion.

[0029] Factors that can affect the selection of the salt include, for example, a melting point that is preferably at least 450°C. In some embodiments, the salt is water-soluble. In some embodiments, the salt is selected to provide a desired pH to the material being added. In some embodiments, the salt does not significantly change the pH of the material.

[0030] In some embodiments, the salt used is sodium chloride (NaCl). Packages with high chloride content have been demonstrated to be difficult to burn. Further, sodium chloride is neutral, highly soluble, and does not affect the pH of the package.

[0031] The combustion-inhibiting salt may be one salt disclosed herein or known in the art, or any number of combinations of salts, and is referred to herein as the "combustion-inhibiting salt". The combustion-inhibiting salt(s) can advantageously be selected to impart desired characteristics to the combustion-inhibiting material.

[0032] In some embodiments, the combustion-inhibiting salt comprises, consists essentially of, or consists of sodium chloride, potassium chloride, sodium bromide, and / or potassium bromide.

[0033] Depending on the desired combustion-inhibiting properties or other physical properties, the salt component may be in the free base form, salt form, or as a complex, or as a solvate. The combustion-inhibiting salt may have any density and any crystal structure.

[0034] Binder In some embodiments, a coating comprising a combustion-inhibiting salt further comprises a binder.

[0035] The binder may be a film-forming material that forms the base of the coating comprising the combustion-inhibiting salt. The combustion-inhibiting salt may be disposed within or on the film formed from the binder. In some embodiments, as discussed in more detail below, the salt is mixed with the binder and applied to the package.

[0036] The binder can adhere the combustion-inhibiting salt to the package. The binder may also be used to adhere the package to itself and other components of the article.

[0037] Suitable binders include, for example, film-forming agents such as polyvinyl alcohol (PVA), rubbers such as gelatin and acacia rubber, starch and its derivatives, polysaccharides, pectin, alginate, wood pulp, cellulose, cellulose derivatives such as carboxymethylcellulose, silica or silicone compounds, clay, and combinations thereof. Suitable binders also include, for example, one or more gelling agents such as alginate, pectin, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, pullulan, xanthan gum, guar gum, carrageenan, agarose, acacia rubber, fumed silica, PDMS, sodium silicate, kaolin, and polyvinyl alcohol. In some cases, the binder may include alginate and / or pectin, and the precursor material may further include a curing agent (such as a calcium source) that can assist in the formation of an amorphous solid. In some cases, the binder may include calcium-crosslinked alginate and / or calcium-crosslinked pectin.

[0038] In some embodiments, the coating contains at least about 0.1 wt%, about 1 wt%, about 10 wt%, about 20 wt%, about 30 wt%, about 35 wt%, about 40 wt%, about 45 wt%, or at least about 50 wt% of binder (all calculated on a dry weight basis). In some cases, the coating contains about 70 wt%, about 65 wt%, about 60 wt%, about 55 wt%, about 50 wt%, about 45 wt%, about 40 wt%, about 35 wt%, or less than about 30 wt% of binder (all calculated on a dry weight basis).

[0039] precursor material In some embodiments, the combustion suppression salt is incorporated into or added to the precursor material used to form a coating on the packaging.

[0040] In some embodiments, the combustion suppression salt is suspended in the precursor material. In some embodiments, the combustion suppression salt is optionally dissolved in the precursor material in the presence of a solvent. The solvent may be aqueous or an organic liquid, and may be polar or nonpolar depending on the material being dissolved and the degree of dissolution.

[0041] The precursor material may contain approximately 3 wt%, 3.5 wt%, 4 wt%, 4.5 wt%, 5 wt%, 5.5 wt%, 6 wt%, 6.5 wt%, 7 wt%, 7.5 wt%, 8 wt%, 9 wt%, 10 wt%, 20 wt%, 30 wt%, 40 wt%, or 50 wt% of combustion suppression salt (all calculated on a dry weight basis).

[0042] In some embodiments, a precursor material containing a combustion-inhibiting salt is applied to the surface of the packaging. This deposits the combustion-inhibiting salt on the surface of the packaging, resulting in a coating on the surface of the packaging.

[0043] In some embodiments, the packaging is in contact with a precursor material, such as a solution or suspension containing a combustion suppression salt. This technique can be used to form a coating containing the combustion suppression salt on the surface or a portion of the surface of the packaging. In some embodiments, the precursor material may be sprayed, printed, coated, or otherwise applied locally to the packaging. This is advantageous because it can result in the formation of a coating of combustion suppression salt that is uniformly distributed across the packaging. Some application methods, such as spraying, printing, and coating, can be more precise and result in a localized coating, or allow for the application of higher concentrations of combustion suppression salt to the packaging.

[0044] The packaging material may be brought into contact with a precursor material containing a combustion suppression salt multiple times to form one or more layers containing the combustion suppression salt. In some embodiments, one layer may be dried before the next layer is applied. In some embodiments, the composition of the layers may differ and may include other components, such as different combustion suppression salts and / or binders. This may result in a specific combustion suppression profile or allow for the utilization of different adhesive properties of the binder. This process may also be repeated to provide a desired thickness of the combustion suppression salt layer and / or a desired amount or concentration of the combustion suppression salt, which is a further advantage. The additional thickness, if the coating is applied to the packaging material, may contribute to improving the structural rigidity of the packaging material or increasing its tensile strength.

[0045] In some embodiments, the precursor material and / or subsequent coating is in the form of an amorphous solid, which may also be referred to as a “integrated solid” (i.e., non-fibrous). In some embodiments, the precursor material or coating may be in the form of a dry gel. An amorphous solid is a solid material that can hold some fluid, such as a liquid, within it. The precursor material or coating in the form of an amorphous solid may contain a binder comprising at least one gelling agent as described herein. Precursor materials or coatings containing an amorphous solid enjoy the advantage of providing increased tensile strength and rigidity to the packaging.

[0046] In some embodiments, the precursor material used to form one layer may be in liquid form for that layer, and the precursor material used to form another layer may be in solid or amorphous solid form. In exemplary embodiments, a precursor material in liquid form containing a binder such as PVA may provide a first layer. A precursor material in amorphous solid form may provide a second layer. The second layer may be in sheet form. Such embodiments provide a packaging in which an amorphous solid sheet is bonded via the first layer. The layer(s) may be positioned in specific parts of the packaging and thus provide localized advantages of the amorphous solid form. The amorphous solid may contain additional components as described herein, and advantageously, it may provide the additional components locally to parts of the packaging.

[0047] The layers may contain the same or different salts. Additionally, the ratio of combustion-inhibiting salts in the precursor material can be changed to produce the desired properties in the layer(s) on the packaging.

[0048] In some embodiments, the coating containing the combustion-suppressing salt is applied to a portion of the packaging, for example, a patch or section of the packaging. The coating may be applied to the inner and / or outer surface of the packaging.

[0049] In some embodiments, the coating is located on the outer surface of the article.

[0050] In some embodiments, the aforementioned packaging surrounds the consumable. As described herein, the consumable may comprise a rod of aerosol-generating material having a first end and a second end. When in use, the article typically has a downstream end that connects to or includes a mouthpiece and / or filter, and an upstream end also referred to as the distal end. A coating containing a combustion-suppressing salt may be applied to the packaging at or toward the distal end of the consumable, spreading over an area of ​​about 1 mm, about 2 mm, about 3 mm, about 4 mm, about 5 mm, about 7 mm, and about 10 mm from the distal end. In some embodiments, it may be preferable that the coating spread over an area between about 5 and 7 mm from the distal end.

[0051] In an exemplary embodiment of the present invention, the precursor material is sprayed to the distal portion of the packaging. This has the advantage of providing combustion suppression salt only where needed, thus reducing waste and unnecessary use of combustion suppression salt, precursor material, and raw materials contained therein.

[0052] Suitable precursor materials for forming this coating may be in the form of a liquid, solution, or suspension, and may further include amorphous solid materials as described herein.

[0053] In another embodiment of the present invention, the precursor material may be applied in the form of a printed patch. In this embodiment, the precursor material may have properties suited to this application method, for example, the precursor material may have a suitable viscosity or may contain a higher concentration of combustion-inhibiting salt. The advantage of this application method is that the printed patch may be of precise size, shape and position on the packaging, and the method provides a more controlled application of the salt to the packaging. The printed patch may be placed on part of or over the packaging. If the patch is located at the distal end of the packaging, this has the advantage of preventing the aerosol-generating material from burning when attempting to light a consumable such as a cigarette.

[0054] Components of the precursor material In some embodiments, the precursor material includes a binder and a combustion suppression salt.

[0055] In some cases, the precursor material contains at least about 0.1 wt%, about 1 wt%, about 10 wt%, about 20 wt%, about 30 wt%, about 35 wt%, about 40 wt%, about 45 wt%, or at least about 50 wt% of binder (all calculated on a dry weight basis). In some cases, the precursor material contains about 70 wt%, about 65 wt%, about 60 wt%, about 55 wt%, about 50 wt%, about 45 wt%, about 40 wt%, about 35 wt%, or less than about 30 wt% of binder (all calculated on a dry weight basis). In some embodiments, the precursor material contains about 20 to about 25 wt% of binder.

[0056] The precursor material may contain an appropriate amount of binder to achieve a favorable viscosity. For example, the precursor material must be viscous enough to form a film and produce a coating of the desired thickness or other physical characteristics. However, if the viscosity of the precursor material is too high, the material may be difficult to apply to the packaging.

[0057] In some embodiments, a precursor material containing a binder imparts adhesive properties to the precursor material. The precursor material may be a viscous composition having adhesive or “glue-like” properties. In some embodiments, the precursor material and the subsequent coating may, advantageously, be used to fix a package in place or to hold the package in a closed state around a rod or aerosol-generating material.

[0058] In some embodiments, the precursor material comprises one or more solvents. The solvents may be included to dissolve one or more components of the precursor material. Additionally or alternatively, the solvents may be included to control properties of the precursor material, such as viscosity or drying behavior under specific conditions. The viscosity of the precursor material may be reduced, for example, to facilitate its application to packaging while maintaining the desired binder and salt content.

[0059] The solvent may comprise one or more liquids, including aqueous and non-aqueous liquids. For example, the solvent may be selected from the group consisting of: water (such as distilled water), benzyl alcohol, ethanol, methanol, triacetin, glycerol, propylene glycol, or combinations thereof. In some embodiments, the solvent is distilled water.

[0060] The solvent may be advantageously selected to be easily removed after the precursor material is applied to the packaging, forming a (dry) coating containing a combustion-inhibiting salt on the surface of the packaging. In some embodiments, the solvent may be removed as a result of the processing step, as will be discussed in more detail below. In some embodiments, the liquid carrier is a volatile solvent that can be advantageously removed by evaporation.

[0061] In some embodiments, the precursor material contains at least about 5 wt%, about 10 wt%, about 20 wt%, about 30 wt%, about 40 wt%, about 50 wt%, about 60 wt%, or at least about 70 wt% of combustion suppression salt (all calculated on a dry weight basis). In some cases, the precursor material contains about 80 wt%, about 75 wt%, about 70 wt%, about 65 wt%, about 60 wt%, about 55 wt%, about 50 wt%, about 45 wt%, about 40 wt%, about 35 wt%, or less of combustion suppression salt (all calculated on a dry weight basis). In some embodiments, the precursor material contains combustion suppression salt from about 50 wt% and optionally has 20 to about 25 wt% of binder.

[0062] Processing of precursor materials The precursor material may optionally be treated to produce a coating when applied to the surface of the packaging. The treatment may include steps involving drying, curing, crosslinking, heating, or any other suitable treatment of the alginate or polymer. This offers the advantage that the coating may have different properties from the precursor material. For example, the precursor material may be liquid but harden on the packaging during the treatment step, imparting a suitable rigidity to the coating. In further examples, the precursor material may be "sticky" before treatment but not sticky after treatment to prevent the packaging from unintentionally adhering to the surface.

[0063] The precursor material may be subjected to different treatments at different locations within the packaging. This offers the advantage that combustion-inhibiting salts and properties can be imparted to different sections of the packaging.

[0064] In some embodiments, some components of the precursor material are removed, for example, by evaporation, while combustion suppression salts (and other non-volatile components) remain deposited on the packaging in the coating.

[0065] In some embodiments, the precursor material or components of the precursor material may remain in the coating formed on the packaging, imparting additional combustion suppression, flavor, aroma, and / or physical characteristics to the coating.

[0066] In some embodiments, the precursor material is not treated, and a coating is formed without further processing.

[0067] coating In some embodiments, the coating may have a thickness of about 0.2 μm to about 10 μm. The coating may have a thickness of about 1 μm, about 2 μm, about 3 μm, about 4 μm, or about 5 μm.

[0068] The combustion suppression salt coating may consist of two or more layers, and the coating thickness described herein refers to the total thickness of these layers. The coating may also contain other additives in addition to the combustion suppression salts(s) disclosed herein. The coating may also be very thin and may not be consistent across the surface of the packaging. The coating thickness may be selected to provide desirable combustion suppression characteristics and to impart satisfactory rigidity and structural integrity to the packaging.

[0069] The thickness of the combustion-inhibiting salt coating can be measured using a microscope such as a scanning electron microscope (SEM) known to those skilled in the art, or any other suitable technique known to those skilled in the art.

[0070] In some cases, the coating thickness may vary across the area by approximately 25%, 20%, 15%, 10%, 5%, or less than 1%. This has the advantage that the rod may have a packaging with a consistent thickness, and as a result, the rod may be more easily adapted to non-flammable aerosol supply systems.

[0071] In some embodiments of the present invention, only a portion of the entire surface area of ​​the packaging has a coating containing a combustion-inhibiting salt. In other embodiments, the entire surface of the packaging has a coating containing a combustion-inhibiting salt.

[0072] In articles having the coating described herein, a portion of the packaging may include a coating containing a combustion-inhibiting salt toward or at the distal end of the consumable. This embodiment enjoys the advantage of preventing the packaging from burning when an attempt is made to light a consumable such as a cigarette.

[0073] The portion of the packaging having a coating containing combustion-inhibiting salts may be about 3 to 15%, or about 3 to 8%, or about 8 to 12% of the total surface area of ​​the packaging. The portion of the packaging having a coating containing combustion-inhibiting salts may be about 1 to 10 mm, about 3 to 8 mm, or about 4 to 6 mm in length from the distal end of the consumable. Alternatively, the portion of the packaging having a coating containing combustion-inhibiting salts may be located at most about 1 mm, about 3 mm, about 5 mm, or about 7 mm from the distal end of the packaging. The portion of the packaging having a coating containing combustion-inhibiting salts may be located at least about 1 mm, about 3 mm, about 5 mm, or about 7 mm from the distal end of the packaging.

[0074] packaging The packaging may include or be substantially composed of paper or a paper-like material. The paper or paper-like material may be between about 20 gsm and about 90 gsm, between about 25 gsm and about 35 gsm, or between about 55 gsm and about 65 gsm. The inventors have found that in the present invention, thicker paper works better, and additionally, thicker paper provides the rod with appropriate structural integrity.

[0075] In some embodiments, the packaging may have multiple holes and / or perforations. This can increase airflow within the article, enhance the user experience of the fragrance properties of the aerosol-generating material, and provide a suitable pressure drop to facilitate use. The location of these holes and / or perforations may be about 0.5 mm to about 10 mm, about 1 mm to about 4 mm, or about 4 mm to about 8 mm from the distal end of the rod. The holes and / or perforations may be of any preferred size and / or number. The size, number, and location of the holes and / or perforations on the packaging may be selected to provide a suitable airflow. For example, more and larger holes and / or perforations can introduce more air into the rod, increase airflow, and therefore provide a suitable pressure drop.

[0076] As used herein, the term “delivery system” is intended to encompass a system for delivering at least one substance to a user, and includes non-combustible aerosol supply systems, such as e-cigarettes and tobacco heating products, which release compounds from aerosol-generating materials without burning the aerosol-generating materials, and composite systems that generate aerosols using a combination of aerosol-generating materials.

[0085] In some embodiments, the non-combustible aerosol supply system, such as the non-combustible aerosol supply device, may include a power source and a control device. The power source may be, for example, a power supply or a heat-generating power source. In some embodiments, the heat-generating power source includes a carbon substrate that can be converted into energy to distribute power in the form of heat to an aerosol-generating material or heat-transfer material adjacent to the heat-generating power source.

[0118] Articles containing shredded rag aerosol-generating material were prepared using a variety of different packaging materials.

[0119] For testing purposes, we attempted to ignite the items using the same method as for flammable cigarettes and then smoke them by blowing on them. The greater the flammability of the packaging material, the less the items burned.

[0120] Example 1 In the first embodiment, various coatings were prepared on a packaging surrounding a rod of aerosol-generating material by applying two layers of precursor material. Different tests used different concentrations of combustion-suppressing salt and binder, as shown in Table 1. The combustion-suppressing salt was NaCl and the binder was PVA glue. All articles did not ignite when attempted to burn and behaved similarly to known combustion-suppressing foils.

[0121] [Table 1]

[0122] Example 2 In another series of tests, the coating according to the present invention was combined with an additional sheet of amorphous solid containing a combustion-inhibiting salt.

[0123] The packaging contained a coating with varying amounts of combustion-inhibiting salts and binders. An amorphous solid sheet surrounded the article at its distal end and covered the distal 5 mm of the paper packaging.

[0124] The tests demonstrated that a combination of an amorphous solid material containing sodium chloride and a coating containing a binder and a combustion-inhibiting salt effectively resisted combustion and functioned similarly to known combustion-inhibiting foils.
