[0093] Some detailed example embodiments are disclosed herein. However, specific structural and functional details disclosed herein are merely representative for purposes of describing example embodiments. Example embodiments may, however, be embodied in many alternate forms and should not be construed as limited to only the example embodiments set forth herein.

[0094] Accordingly, while example embodiments are capable of various modifications and alternative forms, example embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit example embodiments to the particular forms disclosed, but to the contrary, example embodiments are to cover all modifications, equivalents, and alternatives thereof. Like numbers refer to like elements throughout the description of the figures.

[0095] It should be understood that when an element or layer is referred to as being "on," "connected to," "coupled to," “attached to,” “adjacent to,” or "covering" another element or layer, it may be directly on, connected to, coupled to, attached to, adjacent to or covering the other element or layer or intervening elements or layers may be present. In contrast, when anAtty. Dkt. No. 24000NV-001126-WO-POAelement is referred to as being "directly on," "directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout the specification. As used herein, the term "and / or" includes any and all combinations or sub-combinations of one or more of the associated listed items.

[0096] It should be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section from another region, layer, or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of example embodiments.

[0097] Spatially relative terms (e.g., "beneath," "below," "lower," "above," "upper," and the like) may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the term "below" may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0098] The terminology used herein is for the purpose of describing various example embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "includes,"Atty. Dkt. No. 24000NV-001126-WO-POA"including," "comprises," and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0099] While the term “same” or “identical” is used in description of example embodiments, it should be understood that some imprecisions may exist. Thus, when one element is referred to as being the same as another element, it should be understood that an element or a value is the same as another element within a desired manufacturing or operational tolerance range (e.g., ±10%).

[0100] When the terms "about" or “substantially” are used in this specification in connection with a numerical value, it is intended that the associated numerical value includes a manufacturing or operational tolerance (e.g., ±10%) around the stated numerical value. Moreover, when the words "generally" and "substantially" are used in connection with geometric shapes, it is intended that precision of the geometric shape is not required but that latitude for the shape is within the scope of the disclosure. Further, regardless of whether numerical values or shapes are modified as "about" or "substantially," it will be understood that these values and shapes should be construed as including a manufacturing or operational tolerance (e.g., ±10%) around the stated numerical values or shapes.

[0101] The controller may include processing circuitry such as hardware including logic circuits; a hardware / software combination such as a processor executing software stored in a memory; or a combination thereof. For example, the processing circuitry more specifically may include, but is not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a System-on-Chip (SoC), a programmable logic unit, a microprocessor, application-specific integrated circuit (ASIC), etc.Atty. Dkt. No. 24000NV-001126-WO-POA

[0102] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. It will be further understood that terms, including those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0103] Some electronic devices are configured to heat a material (e.g., plant material) to a temperature that is sufficient to release constituents of the material while keeping the temperature below its ignition temperature so as to avoid a self-sustaining burning or a self-sustaining combustion of the material (i.e., in contrast to where a material is lit, such as lit-end cigarettes). Such devices may be characterized as generating an aerosol of constituents released by heating, and may be referred to as heat-not-burn aerosol-generating devices, or heat-not-burn devices.

[0104] It is understood that heating of a material below its ignition temperature may, in some circumstances, produce incidental and insubstantial levels of oxidized or other thermal decomposition byproducts. However, in some embodiments, the heating in aerosol-generating devices is below the pyrolysis temperature of the material so as to produce an aerosol having no or insubstantial levels of thermal decomposition byproducts of the material. Thus, in an example embodiment, pyrolysis of the material does not occur during the heating and resulting production of aerosol. In other instances, there may be incidental pyrolysis, with production of oxidized or other thermal decomposition byproducts at levels that are insignificant relative to the primary constituents released by heating of the material.

[0105] As discussed herein, an aerosol -forming substrate is a material or combination of materials that may yield an aerosol. An aerosol relates to the matter generated or output by the devices disclosed, claimed, and equivalents thereof. The material may include a compoundAtty. Dkt. No. 24000NV-001126-WO-POA(e.g., nicotine, cannabinoid, cannabimimetic agent) that is released when the material is heated. In such an instance, an aerosol including the compound is produced when the material is heated. The heating may be below the ignition temperature so as to avoid a self-sustaining burning or a self-sustaining combustion of the material (i.e., in contrast to where a material is lit, such as lit-end cigarettes). It is understood that heating of a material below its ignition temperature may, in some circumstances, produce incidental and insubstantial levels of oxidized or other thermal decomposition byproducts. However, in some embodiments, the heating in aerosolgenerating devices is below the pyrolysis temperature of the material so as to produce an aerosol having no or insubstantial levels of thermal decomposition byproducts of the material. Thus, in an example embodiment, pyrolysis of the material does not occur during the heating and resulting production of aerosol. In other instances, there may be incidental pyrolysis, with production of oxidized or other thermal decomposition byproducts at levels that are insignificant relative to the primary constituents released by heating of the material.

[0106] The material(s) of the aerosol-forming substrate may include a fibrous material. For instance, the fibrous material may be a botanical material. The fibrous material is configured to release a compound when heated. The compound may be a naturally occurring constituent of the fibrous material. For instance, the fibrous material may be plant material such as tobacco, and the compound released may be nicotine. The term “tobacco” includes any tobacco plant material including tobacco leaf, tobacco plug, reconstituted tobacco, compressed tobacco, shaped tobacco, or powder tobacco, and combinations thereof from one or more species of tobacco plants, such as Nicotiana rustica and Nicotiana tabacum.

[0107] In some example embodiments, the tobacco material may include material from any member of the genus Nicotiana. In addition, the tobacco material may include a blend of two or more different tobacco varieties. Examples of suitable types of tobacco materials that may be used include, but are not limited to, flue-cured tobacco, Burley tobacco, Dark tobacco,Atty. Dkt. No. 24000NV-001126-WO-POAMaryland tobacco, Oriental tobacco, rare tobacco, specialty tobacco, blends thereof, and the like. The tobacco material may be provided in any suitable form, including, but not limited to, tobacco lamina, processed tobacco materials, such as volume expanded or puffed tobacco, processed tobacco stems, such as cut-rolled or cut-puffed stems, reconstituted tobacco materials, blends thereof, and the like. In some example embodiments, the tobacco material is in the form of a substantially dry tobacco mass. Furthermore, in some instances, the tobacco material may be mixed and / or combined with at least one of propylene glycol, glycerin, subcombinations thereof, or combinations thereof.

[0108] The compound in the generated aerosol may also be a naturally occurring constituent of a medicinal plant that has a medically-accepted physiological effect (e.g., therapeutic effect, prophylactic effect). For instance, the medicinal plant may be a cannabis plant or a cannabimimetic plant (i.e., a plant with similar pharmacological effects to those of cannabis). For a cannabis plant, the compound may be a cannabinoid. Cannabinoids interact with receptors in the body to produce a wide range of effects. As a result, cannabinoids have been used for a variety of medicinal purposes (e.g., treatment of pain, nausea, epilepsy, psychiatric disorders). The fibrous material may include the leaf and / or flower material from one or more species of cannabis plants such as Cannabis sativa, Cannabis indica, and Cannabis ruderalis. In some instances, the fibrous material is a mixture of 60-80% (e.g., 70%) Cannabis sativa and 20-40% (e.g., 30%) Cannabis indica. For a cannabimimetic plant, the compound may be a cannabimimetic agent. Cannabimimetic agents interact with receptors in the body to produce similar pharmacological effects as cannabinoids.

[0109] Examples of cannabinoids include tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), cannabidiolic acid (CBDA), cannabidiol (CBD), cannabinol (CBN), cannabicyclol (CBL), cannabichromene (CBC), and cannabigerol (CBG). Tetrahydrocannabinolic acid (THCA) is a precursor of tetrahydrocannabinol (THC), whileAtty. Dkt. No. 24000NV-001126-WO-POAcannabidiolic acid (CBDA) is precursor of cannabidiol (CBD). Tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) may be converted to tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively, via heating. In an example embodiment, heat from a heater (e.g., of the heating assembly 340 shown in FIG. 8) may cause decarboxylation so as to convert the tetrahydrocannabinolic acid (THCA) to tetrahydrocannabinol (THC), and / or to convert the cannabidiolic acid (CBDA) to cannabidiol (CBD).

[0110] In instances where both tetrahydrocannabinolic acid (THCA) and tetrahydrocannabinol (THC) are present, the decarboxylation and resulting conversion will cause a decrease in tetrahydrocannabinolic acid (THCA) and an increase in tetrahydrocannabinol (THC). At least 50% (e.g., at least 87%) of the tetrahydrocannabinolic acid (THCA) may be converted to tetrahydrocannabinol (THC) during the heating. Similarly, in instances where both cannabidiolic acid (CBDA) and cannabidiol (CBD) are present, the decarboxylation and resulting conversion will cause a decrease in cannabidiolic acid (CBDA) and an increase in cannabidiol (CBD). At least 50% (e.g., at least 87%) of the cannabidiolic acid (CBDA) may be converted to cannabidiol (CBD) during the heating.[OHl] Furthermore, the compound which is released may be or may additionally include a non-naturally occurring additive that is subsequently introduced into the fibrous material. In one instance, the fibrous material may include at least one of cotton, polyethylene, polyester, rayon, combinations thereof, or the like (e.g., in a form of a gauze). In another instance, the fibrous material may be a cellulose material (e.g., non-tobacco and / or non-cannabis material). In either instance, the compound introduced may include nicotine, cannabinoids, cannabimimetic agents, and / or flavorants. The flavorants may be from natural sources, such as plant extracts (e.g., tobacco extract, cannabis extract, cannabimimetic extract), and / or artificial sources. In yet another instance, when the fibrous material includes tobacco and / or cannabis, the compound may be or may additionally include one or more flavorants (e.g.,Atty. Dkt. No. 24000NV-001126-WO-POAmenthol, mint, vanilla). Thus, the compound within the aerosol -forming substrate may include naturally occurring constituents and / or non-naturally occurring additives. In this regard, it should be understood that existing levels of the naturally occurring constituents of the aerosolforming substrate may be increased through supplementation. For example, the existing levels of nicotine in a quantity of tobacco may be increased through supplementation with an extract containing nicotine. Similarly, the existing levels of one or more cannabinoids in a quantity of cannabis may be increased through supplementation with an extract containing such cannabinoids. Likewise, the existing levels of one or more cannabimimetic agents in a quantity of cannabimimetic material may be increased through supplementation with an extract containing such cannabimimetic agents.

[0138] In at least one example embodiment, as shown in FIG. 3B, air enters the consumable 200 at the first perforations 208 along a first flow path 350. Once inside the consumable 200, air follows a second flow path 352 through the first annular gap 304 between the outer housing 202 and the inner housing 302. At this point, air is split into a third flow path 354 and a fourth flow path 356. The third flow path 354 is through the second perforations 320 and into the second interior region 318. The fourth flow path 356 is through the aerosol -forming substrate 100. When the air reaches the second end 206, it follows a fifth flow path 358 through the third perforations 322 into the second interior region 318, and then a sixth flow path 360 through the third portion 310 of the inner housing 302 and toward the second perforations 320. Past the second perforations 320, air follows a seventh flow path 362 through the second interior region 318 toward the flow restrictor 324. A portion of the air flows through the orifice 328 of the flow restrictor 324 along an eighth flow path 364. Another portion of the air flows around the flow restrictor 324 along a nineth flow path 366, and through the second annular gap 326 along a tenth flow path 368.
