Preferred heating agents may be, but are not limited to, vanillyl ethyl ether, and preferred cooling agents may be, but are not limited to, eucalyptol or WS-3.
[0025] Aerosol-generating material is a material that can generate an aerosol when, for example, it is heated, irradiated, or otherwise energized. The aerosol-generating material may be, for example, in the form of a solid, liquid, or gel, and may or may not contain active substances and / or flavorings. In some embodiments, the aerosol-generating material may include an "amorphous solid" (which may instead be called a "monolithic solid" (i.e., non-fibrous)). In some embodiments, the amorphous solid may be a dry gel. An amorphous solid is a solid material that can hold some fluid, such as a liquid, within it. In some embodiments, the aerosol-generating material may include, for example, about 50% by weight, 60% by weight, or 70% by weight to about 90% by weight, 95% by weight, or 100% by weight of an amorphous solid.
[0026] The aerosol-generating material may include one or more active substances and / or fragrances, one or more aerosol-forming materials, and optionally one or more other functional materials.
[0027] The aerosol-forming material may contain one or more components capable of forming an aerosol. In some embodiments, the aerosol-forming material may contain one or more of the following: glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, mesoerythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, a mixture of diacetins, benzyl benzoate, benzyl phenylacetate, tributyline, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.
[0028] One or more other functional materials may include one or more of the following: pH adjusters, colorants, preservatives, binders, fillers, stabilizers, and / or antioxidants.
[0029] The material may be present on or within a support to form the substrate. The support may be, for example, paper, cardboard, cardboard, recycled material, plastic material, ceramic material, composite material, glass, metal, or alloy, or may include these. In some embodiments, the support comprises a susceptor. In some embodiments, the susceptor is embedded within the material. In some alternative embodiments, the susceptor is on one or both sides of the material.
[0030] Consumables are articles containing or consisting of aerosol-generating material, some or all of which are intended to be consumed by the user during use. Consumables may also comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol-generating area, a housing, a wrapper, a mouthpiece, a filter, and / or an aerosol modifier. Consumables may also comprise an aerosol generator, such as a heater that releases heat to generate an aerosol in the aerosol-generating material during use.
[0031] An aerosol modifier is a substance configured to modify a generated aerosol, for example, by altering the taste, flavor, acidity, or other properties of the aerosol. The aerosol modifier may be provided in an aerosol modifier release component that is operable to selectively release the aerosol modifier.
[0032] The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may contain, for example, one or more of the following: flavorings, colorings, water, and carbon adsorbents. The aerosol modifier may be, for example, a solid, a liquid, or a gel. The aerosol modifier may be in the form of a powder, thread, or granules. The aerosol modifier may be used without a filter.
[0033] Articles, such as rod-shaped articles, are often named according to their length as follows: "Regular" (typically 68-75mm, e.g., in the range of approximately 68mm-72mm), "Short" or "Mini" (68mm or less), "King Size" (typically 75-91mm, e.g., in the range of approximately 79mm-88mm), "Long" or "Super King" (typically 91-105mm, e.g., in the range of approximately 94mm-101mm), and "Ultra Long" (typically in the range of approximately 110mm-121mm).
[0034] The items are also named according to their circumference: "Regular" (approximately 23-25mm), "Wide" (over 25mm), "Slim" (approximately 22-23mm), "Demi-Slim" (approximately 19-22mm), "Super Slim" (approximately 16-19mm), and "Micro Slim" (less than approximately 16mm).
[0035] Therefore, for example, a king-size super-slim item has a length of approximately 83 mm and a circumference of approximately 17 mm.
[0036] Each form may be manufactured with mouthpieces of different lengths. The mouthpiece length is approximately 30mm to 50mm. The tip paper connects the mouthpiece to the aerosol-generating material and is usually longer than the mouthpiece, for example, 3 to 10mm longer. As a result, the tip paper covers the mouthpiece and overlaps with the aerosol-generating material, for example, in the form of a rod of base material, connecting the mouthpiece to the rod.
[0037] The articles described herein, as well as the aerosol-generating materials and mouthpieces thereof, may be made in any of the above forms, but are not limited to these.
[0038] As used herein, the terms “upstream” and “downstream” are relative terms defined in relation to the direction of the mainstream aerosol drawn through the article or device during use.
[0039] The filament tow materials described herein may include cellulose acetate fiber tow. Filament tow can also be formed using other materials used to form fibers, such as polyvinyl alcohol (PVOH), polylactic acid (PLA), polycaprolactone (PCL), poly(1-4 butanediol succinate) (PBS), poly(butylene adipate-co-terephthalate) (PBAT), starch-based materials, cotton, aliphatic polyester materials, and polysaccharide polymers, or combinations thereof. The filament tow may be plasticized with a plasticizer suitable for tow, such as triacetin if the material is cellulose acetate tow, or the tow may be unplasticized. The tow can have any suitable specifications, such as a cross-section of "Y" shape or "X" shape, and a fiber having a single fineness value of 2.5 to 15 denier per filament, for example, 8.0 to 11.0 denier per filament, and a total fineness value of 5,000 to 50,000 denier, for example, 10,000 to 40,000 denier.
[0040] As used herein, the term “tobacco material” refers to any material including tobacco or its derivatives or substitutes. The term “tobacco material” may include one or more of tobacco, tobacco derivatives, expanded tobacco, re-fed tobacco, or tobacco substitutes. Tobacco material may include one or more of ground tobacco, tobacco fibers, shredded tobacco, extruded tobacco, tobacco stems, tobacco leaflets, re-fed tobacco, and / or tobacco extracts.
[0041] In the figures described herein, similar reference numerals are used to indicate equivalent features, articles, or components.
[0042] Figure 1 is a side cross-sectional view of article 1 for use in a combustible aerosol supply system, for example, as part of a cigarette.
[0043] Article 1 includes an aerosol-generating material 3, in this example a cylindrical rod of tobacco material, and a downstream portion, in this example called a mouthpiece 2, connected to the aerosol-generating material 3 so as to be downstream of the aerosol-generating material 3. The aerosol-generating material 3 supplies an aerosol when burned.
[0044] The aerosol-generating material 3, also referred to herein as the aerosol-generating substrate 3, comprises at least one aerosol-forming material. In this example, the aerosol-forming material is glycerol. In alternative examples, the aerosol-forming material may be another material or a combination thereof, as described herein, for example, propylene glycol.
[0045] In this example, the intake includes a tubular portion 4a formed by a hollow tube, also referred to in this example as a cooling element. The intake 2 includes a component comprising a material body 6 downstream of the tubular portion 4a. In this example, the material body 6 is adjacent to and in contact with the tubular portion 4a. The material body 6 and the tubular portion 4a each define a substantially cylindrical overall shape and share a common longitudinal axis.
[0046] The material body is formed from a sheet material having fibers in the range of 2 mm to 6 mm in length. Such fibers have the advantage of being less likely to absorb and retain aerosol-forming agents (e.g., glycerol as in this example) and / or aerosol modifiers (e.g., menthol). Therefore, a material body containing such fibers may allow a larger amount of aerosol-forming agents and / or aerosol modifiers to reach the user through the material body. The material body can be formed from a sheet material having fibers in the range of 2 mm to 6 mm in average length. In some embodiments, the sheet material included in the material body has fibers in the range of 2 mm to 5 mm, 2 mm to 4 mm, or 2 mm to 3 mm in average length. The fiber length can be selected, for example, based on the form of the cellulose material used to form the sheet material. For example, pine seeds generally result in wood pulp with an average fiber length in the range of about 3.5 mm to 4.4 mm, while ash seeds can result in wood pulp with an average fiber length of about 1.05 mm to 1.20 mm. The average fiber length in a sheet material can be determined, for example, by a scanning electron microscope or by other techniques known to those skilled in the art. For example, at least 70% of the fibers may have a length in the range of 2 mm to 6 mm, or at least 80% or 90% may have a length in that range.
[0047] The material body may comprise one or more fibers with an average length of approximately 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, and 6 mm.
[0048] The length of the fibers can be measured according to appropriate standards, and the fiber length mentioned above can be the length-weighted average value of the fiber lengths.
[0049] In this example, the constituent material body 6 is formed from a corrugated sheet material. In this example, the material body comprises a corrugated sheet material formed to have a corrugated pattern comprising a series of substantially parallel ridges and grooves, with an average spacing between adjacent ridges wider than approximately 0.3 mm. In addition, in this example, the amplitude of the waves is less than approximately 0.7 mm. In other examples, the sheet material may include either an average spacing between adjacent ridges wider than approximately 0.3 mm, or a wave amplitude less than approximately 0.7 mm. In any of these examples, the average density of the material body is approximately 0.1 to approximately 0.25 mg / mm³. 3 Alternatively, the amplitude of the waveform can be greater than 0.7 mm, for example, between 0.7 mm and 1.2 mm.
[0050] The amplitude of the waveform (also known as the "crimp coefficient") refers to the depth of the grooves formed in the sheet material forming the main body by the corrugation process. That is, when the sheet material is corrugated, multiple peaks and valleys are created in the sheet material when viewed from the first side of the sheet material, as shown in Figure 2B. Here, the amplitude of the waveform "A" is the depth of the valley measured from the peak. The corrugation process may form a "zigzag" shape or other shapes. In some embodiments, the spacing between adjacent grooves in the corrugated sheet material is in the range of 0.3 to 2 mm, preferably in the range of 0.4 to 1 mm, i.e., the pitch [P] is in this range. In some embodiments, the spacing between adjacent grooves in the corrugated sheet material is at least 0.4 mm, or at least 0.5, 0.6, 0.7, or 0.8 mm. In some embodiments, the spacing between adjacent grooves in the corrugated sheet material 10 is at most 1.5 mm, preferably at most 1.4, 1.3, 1.2, 1.1, or 1.0 mm. For example, a sheet material can have a waveform where the amplitude of the waveform is less than a distance of 500 μm, and the spacing between peaks (or troughs) is at least 300 μm, at least 400 μm, or at least 500 μm.
[0051] In some embodiments, the sheet material 10 is heated when being corrugated. For example, the sheet material 10 may be passed between corrugating rollers, and one or both of the corrugating rollers are heated.
[0052] It is advantageous that it has been found that using a sheet material, such as paper, having the above-mentioned corrugation pitch and / or amplitude for components of an aerosol supply system shows an improvement in performance. In particular, these relatively small levels of corrugation pitch and amplitude surprisingly result in a lower pressure drop of the material body compared to a body formed from a sheet material with a larger level of corrugation.
[0053] In this example, the density of the material body 6 is about 0.19 mg / mm 3 . In some embodiments, the density of the body 6 is at least 0.1 mg / mm 3 , 0.12 mg / mm 3 , or 0.15 mg / mm 3 . Instead of or in addition to this, the density of the material body 6 can be less than about 0.3 mg / mm 3 , less than 0.25 mg / mm 3 , or less than 0.22 mg / mm 3 . It is advantageous that the density of the material body can be from about 0.1 or 0.15 mg / mm 3 to about 0.25 mg / mm 3 . These values include any additives contained within the material body 6. Before being corrugated to form the material body, the density of the sheet material can be from about 0.2 to 0.5 mg / mm 3 , for example, about 0.25, 0.30, or 0.35 mg / mm 3 .
[0054] In an alternative embodiment, the article 1 can be adapted, for example, by removing the tubular portion 4a and / or by adjusting the level of the aerosol-forming material.
[0055] The material body 6 may be formed from a continuous web of sheet material 6A. In this example, the sheet material 6A is pleated in a manner similar to that of a "crepe filter" to form the material body 6. The sheet material 6A can be manufactured using a CU-20 filter manufacturing machine manufactured by Decouflé®. However, those skilled in the art will understand that other machines can be used to manufacture the material body 6.
[0056] In this example, sheet material 6A contains cellulose. In this example, sheet material 6A is paper.
[0057] In some embodiments, the width of the continuous web of the sheet material 6A is at least 60 mm, at least 70 mm, at least 80 mm, at least 90 mm, at least 100 mm, at least 110 mm, or at least 120 mm.
[0058] In some embodiments, the width of the continuous web of the sheet material 6A is up to 240 mm, up to 230 mm, up to 220 mm, up to 210 mm, up to 200 mm, or up to 190 mm.
[0059] In some embodiments, the width of the sheet material is in the range of 120mm to 200mm, 150mm to 190mm, 160mm to 190mm, or 160mm to 180mm.
[0060] The thickness of the sheet material can be approximately 50 to 100 μm, or approximately 60 to 90 μm. For example, the sheet material may have a thickness of 60 to 70 μm and a weight of 30 to 40 g / m². 2 It is paper.
[0061] The sheet material 6A may contain, in addition to or in lieu of, other materials. For example, in some embodiments, the sheet material 6A includes recycled tobacco formed on the sheet material 6A arranged to form the material body 6. The recycled tobacco contains cellulose. In another embodiment (not shown), the recycled tobacco is manufactured into a uniform plug of the material forming the body 6. The recycled tobacco may optionally be recycled paper tobacco.
[0062] In some embodiments, the sheet material 6A includes paper with a weighing range of 15 gm to 80 gsm, or 20 gsm to 50 gsm.
[0063] In some embodiments, the weighing of the sheet material 6A is at least 15 gsm, at least 20 gsm, at least 25 gsm, or at least 30 gsm.
[0064] In some embodiments, the weighing of the sheet material is 100 gsm or less, 90 gsm or less, 80 gsm or less, or 70 gsm or less. Preferably, the weighing of the sheet material is 60 gsm or less, 50 gsm or less, or 40 gsm or less.
[0065] In some embodiments, the weighing of the sheet material is in the range of 20 gsm to 40 gsm, 24 gsm to 36 gsm, or 30 gsm to 40 gsm.
[0066] The main material body 6 is wrapped in a first plug wrap 7. In this example, the tubular portion 4a and the main material body 6 are joined together using a second plug wrap 9 wrapped around both of these sections. The tip paper 5 is wrapped around the entire length of the mouthpiece 2 and a portion of the rod of the aerosol-generating material 3, and has adhesive on its inner surface to connect the mouthpiece 2 and the rod 3.
[0067] In this example, the tubular portion 4a is formed from multiple layers of paper, which are wound parallel to each other and joined at the seams to form a hollow tube. In this example, the first and second layers of paper are provided in a double tube, but in other examples, three, four, or five or more layers of paper can be used to form triple, quadruple, or quintuple or more tubes. Other structures can be used, such as spirally wound paper layers, cardboard tubes, tubes formed using paper mache-type processes, or molded or extruded plastic tubes.
[0068] In some embodiments, the wall thickness of the tubular portion is at least about 150 μm to a maximum of about 2 mm, 200 μm to 1.5 mm, or 250 μm to 1 mm. In this example, the wall thickness of the tubular portion is about 300 μm. The "wall thickness" of the tubular portion corresponds to the thickness of the radial wall of the tubular portion. This can be measured, for example, using calipers.
[0069] The aeration level of article 1 is approximately 75% of the aerosol drawn through the article. In an alternative embodiment, the aeration level of the article can be 50% to 80%, e.g., 65% to 75%, of the aerosol drawn through the article. These levels of aeration help to slow down the flow of aerosol drawn through the suction port 2, thereby allowing the aerosol temperature to be sufficiently lowered before it reaches the downstream end 2b of the suction port 2. The aeration is supplied directly into the suction port 2 of article 1. In this example, the aeration is supplied into the tubular section 4a, which has been found to be particularly beneficial in assisting the aerosol generation process. In this case, the aeration is supplied through first and second parallel rows of vents 12, formed as laser perforations, located at 13.925 mm and 14.625 mm, respectively, from the downstream mouth end 2b of the suction port 2. These vents 12 pass through the tip paper 5, the second plug wrap 9, and the tubular section 4a. In an alternative embodiment, the vent may be supplied into the suction port at another location. For example, the vent may be supplied into the material body 6.
[0070] In some examples, the aerosol-generating material 3 described herein is a first aerosol-generating material, and the tubular portion 4a may include a second aerosol-generating material. In one example, the wall 4b of the tubular portion 4a includes a second aerosol-generating material. For example, the second aerosol-generating material can be placed on the inner surface of the wall 4b of the tubular portion 4a.
[0071] The second aerosol-generating material comprises at least one aerosol-forming material and at least one aerosol modifier or other sensory material. The aerosol-forming material and / or aerosol modifier may be any or a combination thereof of the aerosol-forming material and / or aerosol modifier described herein.
[0072] In this specification, when an aerosol generated from the aerosol-generating material 3, referred to as the first aerosol, is drawn in through the tubular portion 4a of the mouthpiece, the heat from the first aerosol can aerosolize the aerosol-forming material of the second aerosol-generating material, thereby forming the second aerosol. The second aerosol may contain a flavoring that is any of the flavorings described herein and can be added to or supplement the flavoring of the first aerosol.
[0073] By attaching a second aerosol-generating material to the tubular body 4a, a second aerosol can be generated that enhances or supplements the flavor or appearance of the first aerosol.
[0074] In this example, the circumference of article 1 is approximately 21 mm (i.e., the article is demi-slim). In some embodiments, article 1 has a rod of aerosol-generating material with a circumference longer than 19 mm.
[0075] The outer circumference of the mouthpiece 2 is substantially the same as the outer circumference of the rod of the aerosol-generating material 3, resulting in a smooth transition between these components. In this example, the outer circumference of the mouthpiece 2 is approximately 20.8 mm.
[0076] In some cases, the tip paper 5 contains a citrate such as sodium citrate or potassium citrate. In such cases, the citrate content of the tip paper 5 may be 2% by weight or less, or 1% by weight or less. Reducing the citrate content of the tip paper 5 is thought to help reduce the carbonization phenomenon that may occur during use.
[0077] In this example, the tip paper 5 extends 5 mm to cover the rod of the aerosol generating material 3, but instead, it can be extended 3 mm to 10 mm or 4 mm to 6 mm to cover the rod 3, ensuring adhesion between the mouthpiece 2 and the rod 3. The weight of the tip paper 5 can be greater than that of the plug wrap used in article 1, for example, 40 gsm to 80 gsm, or 50 gsm to 70 gsm, or 58 gsm in this example. At these weight ranges, the tip paper was found to have sufficient flexibility to wrap around article 1 and adhere to itself along the longitudinal wrap seam of the paper, while possessing an acceptable tensile strength. The outer circumference of the tip paper 5 is approximately 21 mm when wrapped around the mouthpiece 2.
[0078] In some embodiments, the weighing capacity of the first plug wrap 7 is less than 50 gsm, for example, about 20 gsm to 40 gsm. However, it should be recognized that the weighing capacity of the first plug wrap 7 may be greater to increase the stiffness of the suction. For example, the weighing capacity of the first plug wrap 7 may be at least 50 gsm, at least 60 gsm, at least 70 gsm, at least 80 gsm, at least 90 gsm, or at least 100 gsm. In some embodiments, the weighing capacity of the first plug wrap 7 is in the range of 50 gsm to 110 gsm, or in the range of 60 gsm to 100 gsm.
[0079] In some embodiments, the weighing capacity of the first plug wrap 7 is at least 20 gsm, or at least 30 gsm. In some embodiments, the weighing capacity of the first plug wrap 7 is at most 120 gsm, 110 gsm, or 100 gsm. In some embodiments, the weighing capacity of the first plug wrap 7 is in the range of 20 gsm to 120 gsm, or in the range of 30 to 100 gsm.
[0080] In some embodiments, the thickness of the first plug wrap 7 is 30 μm to 60 μm, or 35 μm to 45 μm. However, it should be noted that the thickness of the first plug wrap 7 may be thicker to increase the stiffness of the mouthpiece. In some embodiments, for example, the thickness of the first plug wrap 7 may be at least 40 microns, 50 microns, 60 microns, 70 microns, 80 microns, 90 microns, or 100 microns. In some embodiments, the thickness of the first plug wrap 7 is in the range of 40 microns to 120 microns, or in the range of 50 to 100 microns.
[0081] In some embodiments, the first plug wrap 7 is a non-porous plug wrap having permeability of, for example, less than 100 cholesta units, or less than 50 cholesta units. However, in other embodiments, the first plug wrap 7 can be a porous plug wrap with permeability of, for example, more than 200 cholesta units.
[0082] In some embodiments, the length of the material body 6 is less than approximately 20 mm. In this example, the length of the material body 6 is approximately 12 mm.
[0083] In some embodiments, the axial length of the material body 6 is in the range of 10 mm to 20 mm.
[0084] In some embodiments, the aerosol-forming material is applied to the material body 6. For example, the aerosol-forming material may be applied to the sheet material 6A before the sheet material 6A is folded to form the material body 6. The aerosol-forming material may be sprayed onto the sheet material 6A, applied by a brush, or by immersing the sheet material 6 in the aerosol-forming material.
[0085] In some embodiments, the aerosol-forming material may contain one or more of the following: glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, mesoerythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, a mixture of diacetin, benzyl benzoate, benzyl phenylacetate, tributyline, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. For example, the aerosol-forming material may contain triacetin and / or triethyl citrate.
[0086] In some embodiments, at least 0.02 mg of aerosol-forming material is applied to the material body per 1 mm of axial length. In some embodiments, at least 0.03 mg, at least 0.04 mg, or at least 0.05 mg of aerosol-forming material is applied to the material body per 1 mm of axial length.
[0087] In some embodiments, an aerosol-forming material of 0.5 mg or less per 1 mm of the axial length of the material body is applied to the material body. In some embodiments, an aerosol-forming material of 0.4 mg or less or 0.3 mg or less per 1 mm of the axial length of the material body is applied to the material body.
[0088] At least some of the aerosol-forming materials mix with the aerosol as it passes through the material body 6, which helps to make the aerosol feel less dry in the user's mouth.
[0089] In some embodiments, the outer volume of the material body 6 is at least 115 mm². 3 In this example, the material body 6 is generally cylindrical and therefore has a generally cylindrical outer volume. In other embodiments, the outer volume of the material body 6 is 115 mm³. 3 It should be recognized that smaller sizes are also acceptable.
[0090] In this example, the width W1 of the material body 6 (corresponding to the diameter of the material body 6 in this example) is approximately 6.36 mm, and the axial length L1 of the material body 6 is 12 mm. Therefore, the external volume of the material body 6 is approximately 381 mm³. 3 That is the case.
[0091] Contains cellulose and at least 115 mm 3 It was found that the volume of the material body 6A helps remove moisture from the aerosol generated by the aerosol generating material 3 as the aerosol passes through the material body 6A of the mouthpiece 2. In other words, the cellulose containing the sheet material 6A absorbs water from the aerosol. By removing moisture from the aerosol, the aerosol feels colder in the user's mouth.
[0092] In some embodiments, the volume of the material body 6 is at least 19 mm per 1 mm of axial length of the material body. 3 , at least 25 mm per 1 mm of axial length 3 , or at least 30 mm per 1 mm of axial length 3 For example, if the volume of the material body 6 is 19 mm per 1 mm of axial length. 3 Therefore, if the length L1 is 10 mm, the volume of the material itself is 190 mm³. 3 It will become.
[0093] Generally, the larger the volume of the material body 6A, the greater the effect of removing moisture from the aerosol. In some examples, the outer volume of the material body 6 is at least 200 mm³. 3 , at least 300mm 3 , at least 400mm 3 , at least 500mm3 , at least 600mm 3 , at least 700mm 3 , at least 800mm 3 , at least 900mm 3 , or at least 1000mm 3 That is the case.
[0094] In some embodiments, the axial length L1 of the material body 6 is at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm, or at least 10 mm.
[0095] In some embodiments, the axial length L1 of the material body 6 is in the range of 5mm to 20mm, 6mm to 15mm, or 8mm to 14mm.
[0096] In some embodiments, the width W1 of the material body 6 is at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, or at least 9 mm.
[0097] In some embodiments, the outer circumference of the material body 6 is at least 16 mm, at least 18 mm, at least 20 mm, at least 22 mm, at least 25 mm, or at least 26 mm.
[0098] In some embodiments, the pressure drop across the material body 6 is at least 2 mm of water columns, at least 3 mm of water columns, or at least 4 mm of water columns. The pressure drop across the material body may also be at least 5 mm of water columns, at least 6 mm of water columns, at least 7 mm of water columns, at least 8 mm of water columns, at least 9 mm of water columns, at least 10 mm of water columns, or at least 11 mm of water columns.
[0099] In some embodiments, the pressure drop in the material body 6 is less than 30 mm of water column, less than 28 mm of water column, or less than 25 mm of water column.
[0100] In some embodiments, the pressure drop in the material body 6 is approximately 20 mm of water column, 23 mm of water column, or 28 mm of water column.
[0101] In some embodiments, the pressure drop in the material body 6 is in the range of 10 mm to 30 mm of water columns, or 15 mm to 25 mm of water columns.
[0102] In some embodiments, the pressure drop across the material body 6 is at least 1.0 mm of water column per 1 mm of axial length of the material body 6. In some embodiments, the pressure drop across the material body 6 is at least 1.2 mm of water column, 1.5 mm of water column, or 1.8 mm of water column per 1 mm of axial length of the material body 6.
[0103] In some embodiments, the pressure drop across the material body 6 is less than 3.0 mm of water column, 2.8 mm of water column, or 2.6 mm of water column per 1 mm of axial length of the material body 6. In some embodiments, the pressure drop across the material body 6 is less than 2.5 mm of water column, 2.4 mm of water column, or 2.3 mm of water column per 1 mm of axial length of the material body 6.
[0104] In some embodiments, the pressure drop in the material body 6 is in the range of 1.5 mm to 2.5 mm of water column per 1 mm of axial length of the material body 6, or in the range of 1.6 to 2.4 mmWG per 1 mm of axial length of the material body 6.
[0105] In some embodiments, the mass of the material body 6 is at least 50 mg, at least 60 mg, or at least 70 mg. It has been found to be advantageous that using a material body 6 with a larger mass results in a greater amount of water being absorbed from the aerosol. In this example, the mass of the material body is approximately 75 mg.
[0106] In some embodiments, the mass of the material body 6 is less than 150 mg, less than 100 mg, less than 85 mg, or less than 80 mg.
[0107] In some embodiments, the weight of the material body 6 is at least 2 mg per 1 mm of axial length of the material body. In some embodiments, the weight of the material body 6 is at least 3 mg per 1 mm of axial length, or at least 4 mg per 1 mm of axial length.
[0108] In this example, the weight of the material body 6 is approximately 6 mg per 1 mm. That is, in this example, when the axial length L1 of the material body 6 is 12 mm, the total mass of the material body 6 is approximately 74 mg.
[0109] In some embodiments, the material body 6 is a solid cylindrical material body.
[0110] In some embodiments, the hardness of the mouthpiece 2 is in the range of approximately 80% to 95%, or approximately 85% to 90%. The hardness of the mouthpiece 2 may be at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, or at least 92%.
[0111] The hardness of the mouthpiece 2 can be measured according to the following protocol. Where the hardness of a section is referred to herein, that hardness is such that it is determined by the following measurement process. The measurement may be performed using any suitable device such as a Borgwaldt Hardness Tester H10.
[0112] Hardness is defined as the ratio of the height h0 to the height h1 of the body under a specified load, and is expressed as a percentage of h0. Hardness can be expressed as follows: Hardness=(h1 / h0)×100 For individual bodies or bodies included in a rod of multiple sections, hardness measurement is performed at the center of the body in the longitudinal direction.
[0113] A load bar is used to apply a predetermined load to the specimen. The length of the load bar should be significantly longer than the specimen being measured. The specimen being measured is conditioned according to ISO 3402 for a minimum of 48 hours prior to the hardness measurement and is maintained under ISO 3402 environmental conditions during the measurement.
[0114] To perform hardness measurement, the main body is placed inside the Hardness Tester H10, a preload of 2g is applied to the main body, and after 1 second, the initial height h0 of the main body under the 2g preload is recorded. Next, the preload is removed, and a load bar loaded with a 150g load is lowered onto the sample at a speed of 0.6mm / second, and after 5 seconds, the height h1 of the main body under the 150g load is measured.
[0115] The hardness of the mouthpiece is determined as the average hardness of at least 20 mouthpieces measured according to this protocol.
[0116] The hardness of the material body 6 enclosed by the first plug wrap 7 (hereinafter collectively referred to as the “component” for determining hardness) may also be determined using the protocol described above by carefully cutting the article to remove the material body 6 enclosed by the first plug wrap 7. The hardness of the component may be at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, or at least 92%.
[0117] The term "roundness" refers to the ratio of the cross-sectional shape of an object / component to a perfect circle. Roundness is calculated according to the following formula 1.
[0118]
number
[0119] To determine the roundness of article 1, the maximum outer diameter "X" of the components is measured using calipers, and the minimum outer diameter "Y" of the article is measured using calipers (these diameters are perpendicular to the central axis of article 1). The smaller the deviation between the maximum outer diameter X and the minimum outer diameter Y of article 1, the higher the roundness, which indicates that the cross-sectional shape of article 1 is close to a perfect circle.
[0120] In some embodiments, the roundness of article 1 is at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, or at least 95%.
[0121] The hardness of the material body 6 enclosed by the first plug wrap 7 (hereinafter collectively referred to as the "component" for determining roundness) may also be determined using the above protocol by carefully cutting the article to remove the material body 6 enclosed by the first plug wrap 7.
[0122] To determine the roundness of the material body 6 enclosed by the first plug wrap 7 (hereinafter collectively referred to as the "component" for determining roundness), the maximum outer diameter "X" of the component is measured using a caliper, and the minimum outer diameter "Y" of the component is measured using a caliper (these diameters are perpendicular to the central axis of the component). The smaller the deviation between the maximum outer diameter X and the minimum outer diameter Y of the component, the higher the roundness, which indicates that the cross-sectional shape of the component is close to a perfect circle.
[0123] In some embodiments, the roundness of the component (i.e., the roundness of the material body 6 enclosed by the first plug wrap 7) is at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, or at least 95%.
[0124] If the roundness of an item / component is not high, the excessively elliptical downstream portion may get stuck or misaligned in the manufacturing machine. Therefore, high roundness helps ensure that the downstream portion can be processed reliably.
[0125] The first plug wrap 7 and / or the second plug wrap 9 can be bonded around a component(s) of an article by an adhesive applied to a wrap seam that extends longitudinally along the first plug wrap and / or the second plug wrap. Alternatively, or in addition to the above, the first plug wrap 7 and / or the second plug wrap 9 can be bonded directly to the underlying component(s) using an adhesive. In both cases, the adhesive may be selected to be water-soluble to aid in the decomposition of the component(s). In addition, or in addition to the above, the first plug wrap 7 and / or the second plug wrap 9 can be formed from paper, or other materials with improved biodegradability, such as other materials with improved dispersibility when exposed to water.
[0126] Biodegradability can be measured according to the procedures specified in ISO 14855. Components such as those described herein can achieve more than 50% biodegradation in 30 days when exposed to either freshwater or seawater.
[0127] In some embodiments, the length of the tubular portion 4a is less than approximately 50 mm. In some embodiments, the length of the tubular portion 4a is less than approximately 40 mm. In some embodiments, the length of the tubular portion 4a is less than approximately 35 mm. In addition to or alternatively, the length of the tubular portion 4a is at least approximately 10 mm. In some embodiments, the length of the tubular portion 4a is at least approximately 15 mm.
[0128] In some embodiments, the length of the tubular portion 4a is approximately 15 mm to 35 mm, approximately 20 mm to 30 mm, approximately 23 mm to 29 mm, or approximately 25 mm or 29 mm. In this example, the length of the tubular portion 4a is 25 mm.
[0129] In some embodiments, the weight of the second plug wrap 9 is less than 50 gsm. In some embodiments, the weight of the second plug wrap 9 is approximately 20 gsm to 45 gsm. However, it should be noted that the weight of the second plug wrap 9 may be greater to increase the hardness of the spout. For example, the weight of the second plug wrap 9 may be at least 50 gsm, at least 60 gsm, at least 70 gsm, at least 80 gsm, at least 90 gsm, or at least 100 gsm. In some embodiments, the weight of the second plug wrap 9 is in the range of 50 gsm to 110 gsm, or in the range of 60 gsm to 100 gsm.
[0130] In some embodiments, the weighing capacity of the second plug wrap 9 is at least 10 gsm, at least 15 gsm, at least 20 gsm, or at least 25 gsm.
[0131] In some embodiments, the weighing capacity of the second plug wrap 9 is less than 40 gsm, less than 35 gsm, or less than 30 gsm.
[0132] In some embodiments, the weighing capacity of the second plug wrap 9 is in the range of 10–40 gsm, 15–35 gsm, 20–30 gsm, or 25–30 gsm. In some embodiments, the weighing capacity of the second plug wrap 9 is approximately 27 gsm.
[0133] In some embodiments, the thickness of the second plug wrap 9 is 30 μm to 60 μm, or 35 μm to 45 μm. However, it should be noted that the thickness of the second plug wrap 9 may be thicker to increase the hardness of the mouthpiece. In some embodiments, for example, the thickness of the second plug wrap 9 may be at least 40 microns, at least 50 microns, at least 60 microns, at least 70 microns, at least 80 microns, at least 90 microns, or at least 100 microns. In some embodiments, the thickness of the second plug wrap 9 is in the range of 40 microns to 120 microns, or in the range of 50 microns to 100 microns.
[0134] In some embodiments, the second plug wrap 9 is a non-porous plug wrap having a permeability of less than 100 cholesta units, for example, less than 50 cholesta units. However, in alternative embodiments, the second plug wrap 9 can be a porous plug wrap having a permeability of, for example, more than 200 cholesta units.
[0135] The mouthpiece 2 of article 1 comprises an upstream end 3a adjacent to the aerosol generating substrate 3 and a downstream end 2b distal to the aerosol generating substrate 3.
[0136] The pressure drop or pressure difference (also called suction resistance) at the mouthpiece, for example, in the portion of article 1 downstream of the aerosol-generating material 3, is less than about 40 mm of water column. It has been found that such a pressure drop allows a sufficient aerosol containing the desired compound, such as a fragrance compound, to pass through the mouthpiece 2 and reach the consumer. In some embodiments, the pressure drop at the mouthpiece 2 is less than about 20 mm of water column. In some embodiments, particularly improved aerosols have been achieved using a mouthpiece 2 having a pressure drop of less than 15 mm of water column, for example, about 6 mm of water column, about 10 mm of water column, or about 14 mm of water column. Alternatively or in addition to this, the pressure drop at the mouthpiece can be at least 3 mm of water column, at least 4 mm of water column, or at least 5 mm of water column. In some embodiments, the pressure drop at the mouthpiece can be about 5 mm to 20 mm of water column, or 5 mm to 15 mm of water column. These values allow the aerosol to slow down at the mouthpiece 2 as it passes through it, resulting in time for the aerosol's temperature to decrease before it reaches the downstream end 2b of the mouthpiece 2.
[0137] In this example, the aerosol-generating material 3 is wrapped in a wrapper 10. The wrapper 10 can be, for example, paper or foil backed with paper. In this example, the wrapper 10 is substantially airtight. In alternative embodiments, the wrapper 10 has a permeability of less than 100 cholesta units or less than 60 cholesta units. It has been found that using a less permeable wrapper, e.g., one with a permeability of less than 100 cholesta units or less than 60 cholesta units, improves aerosol formation in the aerosol-generating material 3. Although we do not wish to be constrained by theory, this is assumed to be due to a reduction in the loss of aerosol compounds through the wrapper 10. The permeability of the wrapper 10 can be measured according to ISO 2965:2009 for measuring air permeability of materials used as cigarette paper, filter plug wraps, and filter bonding paper.
[0138] In this embodiment, the wrapper 10 includes aluminum foil. The aluminum foil has been found to be particularly effective in enhancing aerosol formation within the aerosol-generating material 3. In this example, the aluminum foil has a metal layer with a thickness of approximately 6 μm. In this example, the aluminum foil has a backing paper. However, in alternative configurations, the aluminum foil can have other thicknesses, for example, 4 μm to 16 μm. The aluminum foil does not necessarily have a backing paper, but it may have a backing made of other materials that help to give the foil adequate tensile strength, or it may not have a backing material at all. Metal layers or foils other than aluminum can also be used. The total thickness of the wrapper is 20 μm to 60 μm, or 30 μm to 50 μm, and this thickness allows the wrapper to have appropriate structural integrity and heat transfer properties. The tensile force that can be applied to the wrapper before it tears can be greater than 3,000 grams, for example, a force of 3,000 to 10,000 grams, or a force of 3,000 to 4,500 grams.
[0139] In some examples, the wrapper 10 surrounding the aerosol-generating material 3 has a high level of permeability, for example, greater than about 1000 cholesta units, greater than about 1500 cholesta units, or greater than about 2000 cholesta units. The permeability of the wrapper 10 can be measured according to ISO 2965:2009 for measuring air permeability of materials used as cigarette paper, filter plug wraps, and filter bonding paper.
[0140] The wrapper 10 may be formed from a material having an inherently high level of permeability, an inherently porous material, or a material having any level of inherent permeability, in which case the final level of permeability is achieved by providing a wrapper 10 having a permeable area or region. By providing a permeable wrapper 10, a path is created for air to enter the article. The wrapper 10 can have permeability such that the amount of air entering through the rod of aerosol-generating material is relatively greater than the amount of air entering the article through the vent hole 12 of the intake. An article having this configuration can generate a more flavorful aerosol, which can satisfy the user more.
[0141] In some embodiments, the aerosol-generating material 3 is provided as a cylindrical rod of aerosol-generating material. Regardless of the form of the aerosol-generating material, the length can be approximately 10 mm to 100 mm. In some embodiments, the length of the aerosol-generating material is in the range of approximately 25 mm to 50 mm, approximately 30 mm to 45 mm, or approximately 30 mm to 40 mm.
[0142] The volume of the aerosol generating material 3 provided is approximately 200 mm³. 3 ~Approximately 4300mm 3 Approximately 500mm 3 ~1500mm 3 , or approximately 1000mm 3 ~approximately 1300mm 3 It can be changed.
[0143] The mass of the aerosol generating material 3 provided can be greater than 200 mg, for example, approximately 200 mg to 400 mg, approximately 230 mg to 360 mg, or approximately 250 mg to 360 mg.
[0144] In some embodiments, the aerosol-generating material or substrate is formed from a tobacco material, such as those described herein, which contains tobacco components.
[0145] In the tobacco materials described herein, the tobacco component may include recycled tobacco. The tobacco component may also include loose leaf tobacco, extruded tobacco, and / or band-cast tobacco.
[0146] The aerosol-generating material 3 may contain recycled tobacco material at a density lower than approximately 700 milligrams (700 mg / cc) per cubic centimeter.
[0147] The tobacco material may be provided in the form of shredded rag tobacco. Shredded rag tobacco can have a cutting width of at least 15 cuts per inch (approximately 5.9 cuts per cm, equivalent to a cutting width of approximately 1.7 mm). In some embodiments, shredded rag tobacco has a cutting width of at least 18 cuts per inch (approximately 7.1 cuts per cm, equivalent to a cutting width of approximately 1.4 mm), or at least 20 cuts per inch (approximately 7.9 cuts per cm, equivalent to a cutting width of approximately 1.27 mm). In one example, shredded rag tobacco has a cutting width of 22 cuts per inch (approximately 8.7 cuts per cm, equivalent to a cutting width of approximately 1.15 mm). Shredded rag tobacco may have a cutting width of 40 cuts per inch (approximately 15.7 cuts per cm, equivalent to a cutting width of approximately 0.64 mm) or less. It has been found that a suitable tobacco material can be obtained with a cutting width of 0.5 mm to 2.0 mm, for example, 0.6 mm to 1.5 mm, or 0.6 mm to 1.7 mm, especially when heated, in terms of the ratio of surface area to volume of the base material 3, as well as the overall density and pressure drop. Shredded rag tobacco can be formed from a mixture of forms of tobacco material, such as a mixture of one or more recycled tobacco, loose leaf tobacco, extruded tobacco, and band-cast tobacco. In some embodiments, the tobacco material includes recycled tobacco, or a mixture of recycled tobacco and loose leaf tobacco.
[0148] In the tobacco materials described herein, the tobacco material may contain filler components. Filler components are generally non-tobacco components, that is, components that do not contain tobacco-derived components. Filler components may be non-tobacco fibers such as wood fibers or pulp or wheat fibers. Filler components may also be inorganic materials such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, or magnesium carbonate. Filler components may also be non-tobacco cast materials or non-tobacco extruded materials. Filler components may be present in an amount of 0 to 20% by weight of the tobacco material, or in an amount of 1 to 10% by weight of the constituent. In some embodiments, filler components are absent.
[0149] The tobacco material may contain 10% to 90% by weight of tobacco leaves, and the aerosol-forming material is supplied with a maximum amount of approximately 10% by weight of tobacco leaves.
[0150] The tobacco materials described herein contain nicotine. The nicotine content is 0.5 to 1.75% by weight of the tobacco material, and may be, for example, 0.8 to 1.5% by weight of the tobacco material. In addition to or instead of this, the tobacco material contains 10% to 90% by weight of tobacco leaves with a nicotine content greater than 1.5% by weight of the tobacco leaves. It has also been found to be advantageous that using tobacco leaves with a nicotine content greater than 1.5% in combination with a base material with less nicotine, such as recycled cigarettes, results in a tobacco material with an appropriate nicotine level but with better perceptual performance than when recycled cigarettes are used alone. Tobacco leaves, for example, shredded rag tobacco, can have a nicotine content of, for example, 1.5% to 5% by weight of the tobacco leaves.
[0151] The tobacco materials described herein may include aerosol modifiers such as any of the flavorings described herein. In one embodiment, the tobacco material contains menthol to form a menthol-containing article. The tobacco material may contain 3 mg to 20 mg of menthol, 5 mg to 18 mg, or 8 mg to 16 mg of menthol. In this example, the tobacco material contains 16 mg of menthol. The tobacco material may contain 2% to 8% by weight of menthol, 3% to 7% by weight of menthol, or 4% to 5.5% by weight of menthol. In one embodiment, the tobacco material contains 4.7% by weight of menthol. Such high levels of menthol can be achieved by using a high proportion of recycled tobacco material, for example, more than 50% by weight of the tobacco material. Alternatively, or in addition thereto, using a large amount of aerosol-generating material, such as tobacco material, can allow for high levels of menthol to be incorporated, for example, in this case about 500 mm 3 More, or preferably about 1000 mm 3 More aerosol-generating materials, such as tobacco materials, are used.
[0152] In the components described herein, where quantities are given in weight percent, to avoid misunderstanding, this refers to the dry weight unless otherwise specifically indicated. Therefore, any water that may be present in the tobacco material or any component is completely disregarded for the purpose of determining the weight percent. The moisture content of the tobacco material described herein may vary, for example, from 5 to 15% by weight. The moisture content of the tobacco material described herein may vary, for example, depending on the temperature, pressure, and humidity conditions under which the component is maintained. The moisture content can be determined by Karl Fischer analysis, as is known to those skilled in the art. On the other hand, to avoid misunderstanding, even when the aerosol-forming material is a liquid-phase component such as glycerol or propylene glycol, any component other than water is included in the weight of the tobacco material. However, when the aerosol-forming material is provided within the tobacco component of the tobacco material or within the filler component of the tobacco material (if present), instead of being added separately to the tobacco material, the aerosol-forming material is not included in the weight of the tobacco component or filler component, but is included in the weight of the "aerosol-forming material" in the weight percent specified herein. All other components present in tobacco are included in the weight of the tobacco component, even if they are non-tobacco derived (for example, non-tobacco fibers in recycled cigarettes).
[0153] In one embodiment, the tobacco material comprises tobacco components as defined herein and an aerosol-forming material as defined herein. In one embodiment, the tobacco material consists substantially of tobacco components as defined herein and an aerosol-forming material as defined herein. In one embodiment, the tobacco material consists of tobacco components as defined herein and an aerosol-forming material as defined herein.
[0154] Figure 3 is a side cross-sectional view of a further article 1' including a mouthpiece 2' containing a hollow tubular element 8. The mouthpiece 2' is substantially the same as the mouthpiece 2 described above in relation to Figure 1, except that at the downstream end 2b, the mouthpiece 2' includes a hollow tubular element 8 formed from a filament tow. In this example, the tubular portion 4a, the material body 6, and the hollow tubular element 8 are joined together using a second plug wrap 9 wrapped around all three of these sections. The further article 1' may be used as a combustible aerosol supply system, for example, for use in a cigarette.
[0155] The material body 6 of article 1' in Figure 3 is the same as the material body 6 described above in relation to Figures 1 and 2. As previously mentioned, the material body 6 is manufactured from a sheet material containing cellulose, for example, the sheet material may be paper. The sheet material is pleated to form the material body 6.
[0156] In this example, the axial length L1 of the material body 6 is approximately 10 mm. However, those skilled in the art will recognize that the axial length L1 of the material body 6 may vary. In some embodiments, the length L1 of the material body 6 is less than approximately 20 mm or less than 15 mm. In some embodiments, the length L1 of the material body 6 is shorter than approximately 10 mm. In addition to or instead of this, the length L1 of the material body 6 may be at least approximately 5 mm. In some embodiments, the length L1 of the material body 6 is at least approximately 6 mm. In some embodiments, the length L1 of the material body 6 is approximately 5 mm to approximately 15 mm, or approximately 6 mm to approximately 12 mm. In some embodiments, the length L1 of the material body is 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.
[0157] The mouthpiece portion that contacts the consumer's lips is typically a paper tube, which is either hollow or surrounds a cylindrical body of filter material. The inclusion of a hollow tubular element 8 has been found to be advantageous in significantly lowering the temperature of the outer surface of the mouthpiece 2' at the downstream end 2b of the mouthpiece that contacts the consumer's mouth during use of the article 1'. In addition, the use of a tubular portion 4a has also been found to significantly lower the temperature of the outer surface of the mouthpiece 2', even upstream of the tubular portion 4a. While we do not wish to be constrained by theory, this is assumed to be due to the tubular portion 4a directing the aerosol closer to the center of the mouthpiece 2', thus reducing heat transfer from the aerosol to the outer surface of the mouthpiece 2'. Furthermore, the material body 6 has been found to remove moisture from the aerosol generated by the aerosol-generating material 3 as the aerosol passes through the material body 6A of the mouthpiece 2, which causes the aerosol to feel cool in the user's mouth.
[0158] In this example, the hollow tubular element 8 is formed from a filament tow. In alternative embodiments, the hollow tubular element may be formed using any structure described herein for the tubular portion 4a.
[0159] The "wall thickness" of the hollow tubular element 8 corresponds to the thickness of the radial wall of the pipe 8. This can be measured in the same way as the wall thickness of the tubular portion. It is advantageous for the wall thickness to be greater than 0.9 mm, and may be 1.0 mm or more. In some embodiments, the wall thickness is substantially constant throughout the wall of the hollow tubular element 8. However, if the wall thickness is not substantially constant, the wall thickness may be greater than 0.9 mm at any point around the hollow tubular element 8, for example, 1.0 mm or more.
[0160] The length of the hollow tubular element 8 is less than approximately 20 mm. In some embodiments, the length of the hollow tubular element 8 is less than approximately 15 mm. In some embodiments, the length of the hollow tubular element 8 is less than approximately 10 mm. In addition to or instead of this, the length of the hollow tubular element 8 may be at least approximately 5 mm. In some embodiments, the length of the hollow tubular element 8 is at least approximately 6 mm. In some embodiments, the length of the hollow tubular element 8 is approximately 5 mm to approximately 20 mm, approximately 6 mm to approximately 10 mm, or approximately 6 mm to approximately 8 mm. In some embodiments, the length of the hollow tubular element 8 is 6 mm, 7 mm, or 8 mm. In this example, the length of the hollow tubular element 8 is 6 mm.
[0161] The density of the hollow tubular element 8 is at least about 0.25 grams per cubic centimeter (0.25 g / cc), for example, at least about 0.3 g / cc. In some embodiments, the density of the hollow tubular element 8 is less than about 0.75 grams per cubic centimeter (0.75 g / cc), for example, less than 0.6 g / cc. In some embodiments, the density of the hollow tubular element 8 is 0.25 g / cc to 0.75 g / cc, 0.3 g / cc to 0.6 g / cc, or 0.4 g / cc to 0.6 g / cc. In some embodiments, the density of the hollow tubular element 8 is about 0.5 g / cc. These densities have been found to provide a good balance between the improved stiffness given by higher density materials and the lower heat transfer properties of lower density materials. For the purposes of the present invention, “density” of the hollow tubular element 8 refers to the density of the filament tow forming the element into which any plasticizer is incorporated. The density can be determined by dividing the total weight of the hollow tubular element 8 by the total volume of the hollow tubular element 8, and the total volume can be calculated using appropriate measurements of the hollow tubular element 8, for example, taken with calipers. If necessary, appropriate dimensions may be measured using a microscope.
[0162] The total fineness of the filament tow forming the hollow tubular element 8 may be less than 45,000 denier, for example less than 42,000 denier. It has been found that this total fineness allows for the formation of a hollow tubular element 8 that is not too dense. In some embodiments, the total fineness is at least 20,000 denier, for example at least 25,000 denier. In some embodiments, the total fineness of the filament tow forming the hollow tubular element 8 is 25,000 to 45,000 denier, for example 35,000 to 45,000 denier. In some embodiments, the cross-sectional shape of the tow filament is "Y" shaped, but in other embodiments, filaments with other cross-sectional shapes, such as "X" shaped, can be used.
[0163] The filament tow forming the hollow tubular element 8 may be thicker than 3 denier per filament. It has been found that this fineness per filament allows for the formation of hollow tubular elements 8 that are not too dense. In some embodiments, the fineness per filament is at least 4 denier, for example, at least 5 denier. In some embodiments, the filament tow forming the hollow tubular element 8 is 4 to 10 denier per filament, for example, 4 to 9 denier. In one example, the filament tow forming the hollow tubular element 8 is formed from cellulose acetate and has a tow of 8Y40,000 containing 18% plasticizer, for example, triacetin.
[0164] The inner diameter of the hollow tubular element 8 may be greater than 3.0 mm. A smaller diameter would increase the velocity of the aerosol passing through the mouthpiece 2' to the consumer's mouth beyond the desired velocity, resulting in the aerosol becoming too hot, potentially reaching temperatures above 40°C or even 45°C. In some embodiments, the inner diameter of the hollow tubular element 8 is greater than 3.1 mm, for example, greater than 3.5 mm or 3.6 mm. In one embodiment, the inner diameter of the hollow tubular element 8 is approximately 3.9 mm.
[0165] In some embodiments, the hollow tubular element 8 contains 15% to 22% by weight of a plasticizer. For cellulose acetate tow, the plasticizer may be triacetin, but other plasticizers such as polyethylene glycol (PEG) can be used. In some embodiments, the hollow tubular element 8 contains 16% to 20% by weight of a plasticizer, for example, about 17%, about 18%, or about 19% of a plasticizer.
[0166] In this example, the tubular portion 4a is the first hollow tubular element, and the hollow tubular element 8 is the second hollow tubular element.
[0167] In this example, the vent is supplied into the tubular portion 4a, as described in relation to Figure 1. In an alternative embodiment, the vent may be supplied elsewhere into the intake, for example, into the material body 6 or into the hollow tubular element 8.
[0168] In the example above, mouthpieces 2 and 2' each comprise a single material body 6. In other examples, mouthpieces 2 and 2' may comprise multiple material bodies. Mouthpieces 2 and 2' may have cavities between the material bodies.
[0169] In some examples, the mouthpieces 2, 2' downstream of the aerosol-generating material 3 may be equipped with a wrapper containing the aerosol modifier described herein or other sensory material, such as a first plug wrap 7 or a second plug wrap 9, or a tip paper 5.
[0170] In some embodiments (not shown), the mouthpieces 2, 2' may include an aerosol modifier release component that is operable to release the aerosol modifier. In some embodiments, the aerosol modifier release component may be operable to selectively release the aerosol modifier. As discussed above, the material body 6 may include fibers in the range of 2 mm to 6 mm in length, thereby resulting in a material body 6 that does not absorb certain aerosol modifiers as the aerosol modifier is released from the aerosol modifier release component.
[0171] The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may contain, for example, one or more of the following: flavorings, colorings, water, and carbon adsorbents. The aerosol modifier may be, for example, a solid, a liquid, or a gel. The aerosol modifier may be in the form of a powder, thread, or granules. The aerosol modifier may be used without a filter.
[0172] The aerosol modifier release component may be, for example, a capsule, a thread, or a bead. In some embodiments, a plurality of aerosol modifier release components may be provided, and a plurality of charcoal particles containing the aerosol modifier may be included.
[0173] In some embodiments, the aerosol modifier release component includes a yarn containing the additive. The yarn may be made from, for example, cellulose acetate or cotton fibers.
[0174] In some embodiments, the aerosol modifier release component has an aerosol modifier in the range of 1 mg to 20 mg, for example, an aerosol modifier in the range of 2 mg to 15 mg.
[0175] Aerosol modifier release components, such as capsules, may be placed inside the main body 6. These aerosol modifier release components, or each aerosol modifier release component, may be combined with the sheet material 6A, for example, by bonding them to the sheet material 6A before the sheet material 6A is formed on the main body 6.
[0176] The aerosol modifier release component may include a capsule. In some embodiments, the aerosol modifier release component comprises a first capsule and a second capsule. The first capsule is located in a first portion of the aerosol modifier release component, and the second capsule is located in a second portion of the aerosol modifier release component downstream of the first portion.
[0177] The aerosol modifier release component may constitute one or more components of Article 1. In some embodiments, the first capsule and the second capsule are located on a material body 6. In one embodiment, the aerosol modifier release component includes two material bodies (not shown), with the first capsule located on the first material body and the second capsule on the second body. In some embodiments, the aerosol modifier release component may, in addition to or instead, comprise one or more tubular elements upstream and / or downstream of one or more material bodies. The aerosol generating component may comprise suction ports 2, 2'.
[0178] In some embodiments, the second capsule is positioned at a distance of at least 7 mm from the first capsule (measured as the distance between the centers of the first and second capsules). In some embodiments, the second capsule is positioned at a distance of at least 8 mm, 9 mm, or 10 mm from the first capsule. It has been found that increasing the distance between the first and second capsules increases the temperature difference between the first and second capsules.
[0179] The first capsule contains an aerosol modifier. The second capsule contains an aerosol modifier which may be the same as or different from the aerosol modifier of the first capsule. In some embodiments, the user can selectively rupture the first and second capsules by applying an external force to an aerosol modifier release component to release the aerosol modifier from each capsule.
[0180] In some embodiments, the capsule or each capsule comprises an outer shell and an inner core.
[0181] The shell of each capsule may be solid at room temperature. The shell may contain alginate, consist of alginate, or be substantially composed of alginate. However, it should be noted that in alternative embodiments, the shell may be formed from different materials. For example, the shell may instead contain, consist of, or be substantially composed of gelatin, carrageenan, or pectin. The shell may contain, consist of, or be substantially composed of one or more of alginate, gelatin, carrageenan, or pectin.
[0182] The shell of each additive capsule may be impermeable to the core aerosol modifier, or substantially impermeable. Therefore, the shell initially prevents the core modifier from leaking out of the capsule. When the user wishes to modify the aerosol, they crush the capsule shell to release the modifier.
[0183] In some embodiments (not shown), the capsule (or each capsule) further comprises a carrier material, which may include, for example, gelatin.
[0184] In some embodiments, the diameter of this capsule (or each capsule) is in the range of 1 mm to 5 mm, or 2 mm to 4 mm. In some embodiments, the diameter of this capsule (or each capsule) is approximately 3 mm. This capsule (or each capsule) may be generally spherical. In other examples, capsules of other shapes and sizes may be used.
[0185] The total weight of each capsule may be in the range of approximately 5 mg to approximately 50 mg, or approximately 10 mg to approximately 30 mg. In some embodiments, the weight of each capsule is approximately 14 mg.
[0186] In some embodiments, one or more aerosol modifier-releasing components are contained within the material body 6, which is formed from a sheet material weighing less than 40 gsm, for example, less than 35 or 30 gsm. This helps to lower the density of the material body 6 in order to counteract the presence of the aerosol modifier-releasing components within the body 6 (otherwise the body 6 may become rigid).
[0187] In some embodiments, one or more aerosol modifier-releasing components are contained within the material body 6, which is formed from a sheet material with a width of less than 100 mm, for example, less than 90 mm or 80 mm. This helps to reduce the density of the material body 6 in order to counteract the presence of the aerosol modifier-releasing components within the body 6 (otherwise the body 6 may become rigid).
[0188] In some embodiments, this capsule (or each capsule) is positioned in the center of the longitudinal axis of the mouthpiece 2.
[0189] As discussed above, this capsule (or each capsule) may have a core-shell structure. That is, the encapsulating material or barrier material forms a shell around a core containing the aerosol modifier. The shell structure prevents the aerosol modifier from moving during storage of the article, but allows for the controlled release of the aerosol modifier, also called the aerosol modifier, during use.
[0190] In some cases, the barrier material (also referred to herein as the encapsulating material) is fragile. This capsule (or each capsule) is crushed, ruptured, or destroyed by the user to release the encapsulated aerosol modifier. Typically, one or more capsules are destroyed immediately before heating begins, but the user can choose when to release the aerosol modifier from the capsule. The user can then choose to destroy other capsules later, for example, after heating has begun. The user can choose to destroy the other capsule once a portion of the aerosol has been released from the aerosol-generating material, so that the remaining aerosol-generating material is modified by the aerosol modifier from the other capsule. Alternatively, the user may choose to destroy multiple capsules simultaneously.
[0191] The term "destructible capsule" refers to a capsule whose shell can be broken by pressure to release the core, and more specifically, a capsule whose shell can be ruptured by pressure applied by the user's finger when the user wishes to release the capsule's core.
[0192] In some cases, the barrier material is heat-resistant. That is, in some cases, the barrier will not rupture, melt, or otherwise become non-functional at the temperature reached at the capsule's location during the operation of the aerosol supply device. For example, a capsule placed in the mouthpiece may be exposed to temperatures in the range of, for example, 30°C to 100°C, and the barrier material can continue to hold the liquid core up to at least about 50°C to 120°C.
[0193] In other cases, the capsule (or each capsule) releases its core components upon heating, for example, by melting the barrier material or by expansion of the capsule resulting in the rupture of the barrier material.
[0194] The total weight of each capsule may be in the range of approximately 1 mg to 100 mg, approximately 5 mg to 60 mg, approximately 8 mg to 50 mg, approximately 10 mg to 20 mg, or approximately 12 mg to 18 mg.
[0195] The total weight of the core combination may be in the range of approximately 2 mg to 90 mg, approximately 3 mg to 70 mg, approximately 5 mg to 25 mg, approximately 8 mg to 20 mg, or approximately 10 mg to 15 mg.
[0196] In some embodiments, the capsule (or each capsule) comprises the core and shell described above. Each capsule may exhibit a crush strength of about 4.5 N to about 40 N, about 5 N to about 30 N, or about 5 N to about 28 N (e.g., about 9.8 N to about 24.5 N). The capsule burst strength of each capsule can be measured by removing the capsule from the material body 6 and using a force meter to measure the force at which the capsule bursts when pressed between two flat metal plates. A preferred measuring device is a Sauter FK50 force meter, which has a flat mounting head, and can be used to crush the capsule against a flat, hard surface having a surface similar to the mounting.
[0197] The capsule (or each capsule) may be substantially spherical, and its diameter may be at least about 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 2.0 mm, 2.5 mm, 2.8 mm, or 3.0 mm. The diameter of the capsule (or each capsule) may also be less than about 10.0 mm, less than 8.0 mm, less than 7.0 mm, less than 6.0 mm, less than 5.5 mm, less than 5.0 mm, less than 4.5 mm, less than 4.0 mm, less than 3.5 mm, or less than 3.2 mm. Exemplarily, the diameter of the capsule may be in the range of about 0.4 mm to about 10.0 mm, about 0.8 mm to about 6.0 mm, about 2.5 mm to about 5.5 mm, or about 2.8 mm to about 3.2 mm. In some cases, the diameter of the capsule (or each capsule) may be about 3.0 mm. These sizes are particularly suitable for incorporating the capsule into the articles described herein.
[0198] In some embodiments, the cross-sectional area of each capsule at the point of maximum cross-sectional area is less than 28% of the cross-sectional area of the mouthpiece 2 on which the capsule is provided, for example, less than 27% or less than 25%. For example, in a spherical capsule with a diameter of 3.0 mm, the maximum cross-sectional area of the capsule is 7.07 mm². 2 In the 21mm outer diameter mouthpiece described herein, the outer diameter of the material body 6 is 20.8mm, and the radius of this component is 3.31mm, which is 34.43mm. 2 This corresponds to the cross-sectional area of the mouthpiece 2. In this example, the cross-sectional area of the capsule is 20.5% of the cross-sectional area of mouthpiece 2. As another example, if the diameter of the capsule is 3.2 mm, its maximum cross-sectional area is 8.04 mm². 2 This is the case. In this case, the cross-sectional area of the capsule is 23.4% of the cross-sectional area of the material body 6. A capsule having a maximum cross-sectional area smaller than 28% of the cross-sectional area of the mouthpiece 2 on which the capsule is provided has the advantage, compared to a capsule with a larger cross-sectional area, that the pressure drop at the mouthpiece 2 is reduced, and when the aerosol passes through the mouthpiece 2, there is sufficient space left around the capsule for the aerosol to pass through without the material body 6 removing a large amount of aerosol mass. In some embodiments, a first capsule and a second capsule are provided, and these may be the same size or different sizes.
[0199] Figure 4 is a side cross-sectional view of a further article 1'' including a mouthpiece 2''. The mouthpiece 2'' is substantially the same as the mouthpiece 2 described above in relation to Figures 1 and 2. The difference is that the material body 6 of article 1'' is located upstream of the tubular portion 4a. The further article 1'' may be used as a combustible aerosol supply system, for example, for use with a cigarette.
[0200] In this example, the tubular portion 4a and the material body 6 are joined using a second plug wrap 9 that is wrapped around both sections.
[0201] The material body 6 of article 1'' in Figure 4 is the same as the material body 6 described above in relation to Figures 1 to 3. As previously mentioned, the material body 6 is manufactured from a sheet material containing cellulose, for example, the sheet material may be paper. The sheet material is pleated to form the material body 6.
[0202] The main material body 6 is positioned at the upstream end 2a of the mouthpiece 2'. The main material body 6 is adjacent to the aerosol generating material 3.
[0203] The tubular portion 4a is positioned at the downstream end 2b of the suction port 2'', and thus forms a cavity at the downstream end 2b. The tubular portion 4a is positioned downstream of the material body 6. In this example, the tubular portion 4a is directly adjacent to the material body 6.
[0204] The axial length L2 of the tubular portion 4a is at least 20 mm, for example, at least 22 mm. In this example, the axial length L2 of the tubular portion 4a is approximately 25 mm.
[0205] It was found that when the axial length L2 of the tube is at least 20 mm, the aerosol is significantly cooled as it passes through the tubular portion 4a. In addition, as mentioned above, the cellulose in the sheet material of the main body 6 absorbs water from the aerosol. By removing moisture from the aerosol, the user perceives the aerosol as cold in their mouth.
[0206] In some embodiments, the tubular portion 4a is provided with one or more vents, which also contribute to the cooling of the aerosol.
[0207] In some embodiments, the tubular portion 4a is manufactured from paper.
[0208] Figure 5 is a side cross-sectional view of a further article 1''' including a mouthpiece 2'''. The mouthpiece 2''' is substantially the same as the mouthpiece 2 described above in relation to Figures 1 and 2. The difference is that the mouthpiece 2''' further comprises a tubular element 20 disposed within the material body 6. The further article 1''' may be used as a combustible aerosol supply system, for example, for use with a cigarette.
[0209] In this example, the tubular portion 4a and the material body 6 are joined using a second plug wrap 9 that is wrapped around both sections.
[0210] The material body 6 of article 1''' in Figure 5 is the same as the material body 6 described above in relation to Figures 1 to 3. As previously mentioned, the material body 6 is manufactured from a sheet material containing cellulose, for example, the sheet material may be paper. The sheet material is pleated to form the material body 6.
[0211] The tubular element 20 may be, for example, a paper or plastic tube placed within the material body 6. The tubular element 20 forms a cavity 21 within the material body 6. Optionally, the tubular element 20 is positioned substantially radially centered within the material body 6.
[0212] In this example, the cavity 21 extends to the downstream end 2b of the mouthpiece 2''''.
[0213] In this example, the axial length L1 of the material body 6 is approximately 10 mm. However, those skilled in the art will recognize that the axial length L1 of the material body 6 may vary. In some embodiments, the length L1 of the material body 6 is shorter than approximately 15 mm. In some embodiments, the length L1 of the material body 6 is shorter than approximately 10 mm. In addition to or instead of this, the length L1 of the material body 6 may be at least approximately 5 mm. In some embodiments, the length L1 of the material body 6 is at least approximately 6 mm. In some embodiments, the length L1 of the material body 6 is approximately 5 mm to approximately 15 mm, approximately 6 mm to approximately 12 mm, or approximately 6 mm to approximately 12 mm. In some embodiments, the length L1 of the material body 6 is 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.
[0214] In some embodiments, the axial length L3 of the tubular element 20 is at least 4 mm, for example, about 5 mm.
[0215] The cavity 21 was found to facilitate the cooling of the aerosol. The portion 6b of the material body 6 surrounding the tubular element 21 was found to effectively insulate the user's lips from the heat of the aerosol. For example, in embodiments in which the material body 6 is manufactured from sheet material placed inside the material body, the multiple layers of sheet material of the material body 6 are considered to help insulate the user's lips from the heat of the aerosol. In some embodiments, optionally, there may be gaps, e.g., voids, between the layers of sheet material that contribute to the insulating effect.
[0216] Furthermore, the main material 6 may be more easily biodegradable than a structure in which a tubular portion of cellulose acetate is instead provided at the downstream end 2b of the mouthpiece.
[0217] The material body 6 may be manufactured from multiple rods 22 of different lengths, in this example four rods, as shown in Figure 6. The rods are cut along line CC to form individual material bodies 6, each having a tubular element 20 with a corresponding cavity 21.
