DETAILED DESCRIPTION OF THE INVENTION

[0042] As used herein, the term "delivery system" is intended to encompass a system that delivers at least one substance to a user; Combustion aerosol delivery systems, such as cigarettes, cigarillos, cigars, and tobacco for pipes or hand-rolled or homemade cigarettes (whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, tobacco substitutes, or other smokable materials); and non-combustion aerosol delivery systems that release compounds from aerosol-forming materials without burning the aerosol-forming materials, such as e-cigarettes, tobacco heating products, and hybrid systems that generate aerosols using a combination of aerosol-forming materials.

[0043] According to the present disclosure, a "combustion-based" aerosol delivery system is one in which the constituent aerosol-generating materials (or components thereof) of the aerosol delivery system are combusted or burned during use to facilitate delivery of at least one substance to a user.

[0044] In some embodiments, the delivery system is a combustion aerosol delivery system, such as a system selected from the group consisting of a cigarette, a cigarillo, and a cigar.

[0046] According to the present disclosure, a "non-combustion" aerosol delivery system is one in which the constituent aerosol-generating materials (or components thereof) of the aerosol delivery system are not combusted or burned to facilitate delivery of at least one substance to a user.

[0047] In some embodiments, the delivery system is a non-combustion aerosol delivery system, such as a powered non-combustion aerosol delivery system.

[0048] In some embodiments, the non-combustion aerosol delivery system is an electronic cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it should be noted that the presence of nicotine in the aerosol-generating material is not a requirement.

[0049] In some embodiments, the non-combustion aerosol delivery system is an aerosol-generating material heating system, also known as a non-combustion heating system. One example of such a system is a tobacco heating system.

[0050] In some embodiments, the non-combustion aerosol delivery system is a hybrid system that generates an aerosol using a combination of aerosol-generating materials, where one or more aerosol-generating materials can be heated. Each aerosol-generating material can be, for example, in solid, liquid, or gel form and can contain nicotine or not. In some embodiments, the hybrid system includes a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material can include, for example, tobacco or a non-tobacco product.

[0051] Typically, a non-combustion aerosol delivery system may include a non-combustion aerosol delivery device and a consumable item for use with the non-combustion aerosol delivery device.

[0052] In some embodiments, the present disclosure relates to consumables, sometimes referred to as articles throughout this disclosure, that comprise aerosol-generating materials and are configured for use with non-combustion aerosol delivery devices.

[0053] In some embodiments, a non-combustion aerosol delivery system, e.g., the non-combustion aerosol delivery device, can include a power source and a controller. The power source can be, for example, an electrical power source or a heat generating power source. In some embodiments, the heat generating power source includes a carbon substrate that can be energized to deliver power in the form of heat to an aerosol-generating material or a heat transfer material proximate the heat generating power source.

[0062] The aerosol-generating film may be discontinuous. For example, the aerosol-generating film may include one or more discrete portions or regions of aerosol-generating material, such as dots, stripes, or lines, that may be supported on a substrate. In such embodiments, the substrate may be planar or non-planar.

[0063] The aerosol-generating film can be formed by combining a binder, such as a gelling agent, with one or more other ingredients, such as a solvent, such as water, an aerosol-forming agent, and one or more substances to be delivered, to form a slurry, and then heating the slurry to volatilize at least a portion of the solvent and form the aerosol-generating film.

[0064] The slurry can be heated to remove at least about 60%, 70%, 80%, 85%, or 90% by weight of the solvent.

[0090] Aerosol modifier-releasing components are often used in delivery systems. A consumer can activate the aerosol modifier-releasing component 8 so that the aerosol modifier therein is released and imparts a property to the aerosol flowing through the delivery system 1. However, the aerosol modifier tends to be absorbed by the body of material 13 in which the aerosol modifier-releasing component 8 is embedded. This inhibits the aerosol modifier's ability to impart said property to the aerosol, thus reducing the intensity of the aerosol modifier's desired effect.

[0091] FIG. 2 shows a cross-sectional view of one embodiment of the delivery system shown in FIG. 1 taken along line AA through component 3. As shown in FIG. 2, component 3 further includes a first sheet of material 9 that forms at least a portion of body 13 and surrounds aerosol modifier-releasing component 8, and a second sheet of material 10 that surrounds first sheet of material 9. At least a portion of first sheet of material 9 has a lower absorbency than second sheet of material 10. To reduce the absorbency of first sheet of material 9, a portion of first sheet of material 9 is treated with a coating. The coating is one of silicone, starch, glassine, clay, silica, alginate, or guar. However, it should be understood that other coating materials may be suitable to achieve the desired functionality.

[0092] In some embodiments, the portion of the first sheet of material that is treated forms more than 40%, more than 50%, more than 60%, more than 70%, more than 80%, or more than 90% of the first sheet of material, or the entire first sheet of material is treated.

[0093] Because the first sheet of material 9 surrounding the aerosol modifier-releasing component 8 has a lower absorbency than the second sheet of material 10, when the aerosol modifier-releasing component 8 is activated, the aerosol modifier is less absorbed into the body of material 13 9 and therefore has a stronger effect on the aerosol. In other words, reduced absorption of the aerosol modifier into the body of material 13 improves the aerosol modifier's ability to impart properties to the aerosol.

[0094] As shown in Figure 2, body of material 13 is formed from first sheet of material 9 and second sheet of material 10. Body of material 13 is wrapped in plug wrap 5. Alternatively, body of material 13 is formed from first sheet of material 9 and second sheet of material 10 is plug wrap 5.

[0095] The first sheet of material 9 is a sheet of nonwoven material, such as a paper material, having a thickness of 70 μm to 90 μm. The second sheet of material 10 is also a sheet of nonwoven material, such as a paper material, having a thickness of 70 μm to 350 μm. In some embodiments, the width of the first sheet of material 9 is smaller than the width of the second sheet of material 10. For example, the width of the first sheet of material 9 is 120 mm to 180 mm, and the width of the second sheet of material 10 is 140 mm to 200 mm. Furthermore, the metric basis weight of the first sheet of material 9 and the second sheet of material 10 is 20 gsm to 80 gsm. As shown in FIG. 2, the first sheet of material 9 and / or the second sheet of material 10 are corrugated. Furthermore, the first sheet of material 9 and / or the second sheet of material 10 are biodegradable. However, it should be understood that in other embodiments, the first sheet of material 9 and the second sheet of material 10 may have other configurations.

[0096] The plug wrap 5 wrapped around the body of material 13 may be treated to reduce its absorbency by treating it with any one of silicone, starch, glassine, clay, silica, alginate, or guar, although it should be understood that other coating substances may be suitable to achieve the desired functionality.

[0097] FIG. 3 shows a cross-sectional view of another embodiment of the delivery system shown in FIG. 1 taken along line AA through component 3. As shown in FIG. 3, body of material 13 includes sheet of material 11 surrounding aerosol modifier-releasing component 8. Body of material 13 is wrapped in plug wrap 5. At least a portion of sheet of material 11 is treated to have lower absorbency than sheet of material 11 had prior to said treatment. As seen in FIG. 3, sheet of material 11 includes surface 12 facing the aerosol modifier-releasing component. In particular, the treatment of sheet of material 11 includes treatment of surface 12 of sheet of material 11 facing aerosol modifier-releasing component 8. To reduce the absorbency of sheet of material 11, sheet of material 11 is treated with a coating. The coating is any one of silicone, starch, glassine, clay, silica, alginate, or guar. However, it should be understood that other coating materials may be suitable to achieve the desired functionality.

[0098] In some embodiments, the portion of the sheet of material that is treated forms more than 40%, more than 50%, more than 60%, more than 70%, more than 80%, or more than 90% of the first sheet of material, or the entire sheet of material is treated.

[0099] 2, because the surface 12 of the sheet of material 11 surrounding the aerosol modifier-releasing component 8 has a lower absorbency than the sheet of material 11, when the aerosol modifier-releasing component 8 is activated, the aerosol modifier is less absorbed by the first sheet of material 11 and therefore has a stronger effect on the aerosol. In other words, reduced absorption of the aerosol modifier by the first sheet of material 11 improves the aerosol modifier's ability to impart properties to the aerosol.

[0100] Sheet of material 11 is a nonwoven sheet of material, such as a paper material. As shown in Figure 3, sheet of material 11 is corrugated. Furthermore, sheet of material 11 is biodegradable. However, it should be understood that in other embodiments, first sheet of material 11 may have another configuration.

[0101] The plug wrap 5 around the body of material 13 may be treated to reduce its absorbency and / or permeability by treating it with any one of silicone, starch, glassine, clay, silica, alginate, or guar, although it should be understood that other coating substances may be suitable to achieve the desired functionality.

[0102] Figure 4 is a data table showing the results of a medium-chain triglyceride (MCT) absorbency test. The method used is a modified version of the Cobb test, in which a conditioned specimen is weighed before and after one side of the specimen is exposed to MCT under specified conditions. Excess MCT is removed from the specimen surface before final weighing, and the amount of MCT absorbed per unit area is calculated.

[0103] The MCT absorbency tester consists of a device that allows for uniform wetting of one side of the test specimen at the moment the immersion period begins and allows for rapid removal of the MCT at the end of the test period. 2 The test specimen is secured to a flat base plate having a cylindrical cup or ring with an internal cross-sectional area of ​​4.0 cm and a height of 4.0 cm. The base plate has a rubber mat on it that is larger than the outer dimensions of the ring on which the specimen is secured.

[0104] The MCT absorbability test was carried out as follows.

[0105] ·Cut the test specimen into 7.0 x 7.0 cm squares and weigh them to the nearest 1.0 mg.

[0106] Place the test specimen on a rubber mat on a metal plate. Wipe the ring dry (do not use heat), place it on the test specimen, and clamp it in place with a crossbar (or another clamping mechanism) firmly enough to prevent any leakage between the ring and the test specimen.

[0107] Using a syringe, pour 25 mL of MCT into the ring as quickly as possible to obtain a 2.5 cm head. Immediately start a stopwatch. After 5 seconds, quickly pour the MCT out of the ring, being careful not to drip any MCT onto the outer portion of the specimen.

[0108] While holding the ring in place by pressing down on it with one hand, release the clamping mechanism and swing the crossbar out of the way. Carefully but quickly, remove the ring and place the specimen, wet side up, on a sheet of blotting paper placed on a flat, rigid surface. Place a second piece of blotting paper on top of the specimen and, without applying any additional pressure to the roller, remove excess MCT by running a hand roller back and forth once over the pad.

[0109] After removing excess MCT, immediately reweigh the test piece to the nearest 1.0 mg.

[0110] Flavor Absorption Units over 5 seconds (FAU5) can be calculated using the following formula: Flavor absorption unit (g / m 2 ) = [final weight (g) - initial weight (g)] / test area (m 2 ) In this case, the test area is 0.0001 m 2 is.

[0111] A lower FAU5 indicates a material with poor absorption properties. In one particular embodiment, the FAU5 of the first sheet of material 9 and the sheet of material 11 is 60 g / m 2 Less than 50g / m 2 Less than 40g / m 2 Less than 30g / m 2 Less than 20g / m 2 Less than 10g / m 2 Less than or equal to 5g / m 2 is less than.

[0112] Figure 5 is a data table showing the results of the contact angle tests. Contact angle measurements were made using an OCA 15 Dataphysics goniometer and recorded at 25 frames per second. For each experiment, a droplet (7 μL) of flavoring agent was placed on each paper surface. Image analysis software was used to calculate the contact angle, and the angle calculation was adjusted by circular fitting. Measurements were taken at instantaneous contact angles (0 seconds) and at 5 seconds.

[0113] A low difference in the average contact angles at 0 and 5 seconds indicates a material with low absorption properties. In certain embodiments, the difference in the average contact angles between first sheet of material 9 and sheet of material 11 at 0 and 5 seconds is less than 40°, less than 30°, or less than 20°.

[0114] Figure 6 is a data table showing the results of water absorption (TAPPI 432 method). Due to the high absorbency of the samples, the standard TAPPI 432 procedure was followed, using 10 μl of water. A droplet analyzer (Attension Theta Optical Tensiometer) was used to place a droplet on the sample, ensuring accurate absorption time measurements. The sample was recorded with a high-frame-rate camera parallel to the surface of the material. The time to absorb a specified volume was determined by frame-by-frame inspection of the optical tensiometer's video output. This absorption time was defined as the difference between the time the droplet left the needle and the time when the liquid was no longer considered appreciably present on the paper's surface. The samples were removed from the standard TAPPI atmosphere for a short period (<30 minutes) and tested at room temperature. A shorter average water drop absorption time indicates a more absorbent material. In some embodiments, the average water drop absorption time of first material sheet 9 and material sheet 11 is less than 3 seconds, less than 2 seconds, or less than 1 second.

[0115] Figure 7 is a data table showing the results of the oil drop absorption test. Due to the rapid absorption of the material, a method similar to the TAPPI 432 standard was used. A syringe equipped with a 12-gauge needle was filled with medium-chain triglyceride and attached to a droplet analyzer (Attension Theta Optical Tensiometer) perpendicular to the surface of the sample. A 10 μl drop was then formed at the tip of the needle. The medium-chain triglyceride drop was then mechanically dropped onto the surface, and the progressive absorption time by the sample was recorded. The time to absorb a specified volume was determined by frame-by-frame inspection of the optical tensiometer's video output. This absorption time was defined as the difference between the time the drop left the needle and the time when the liquid was no longer clearly present on the paper surface. Samples were tested at room temperature after being briefly removed (<30 min) from the standard TAPPI atmosphere. A lower average oil drop absorption time indicates a material with better absorption properties. In some embodiments, the average oil droplet absorption time of first sheet of material 9 and sheet of material 11 is less than 250 seconds, less than 200 seconds, less than 150 seconds, less than 100 seconds, less than 50 seconds, or less than 25 seconds.
