DETAILED DESCRIPTION OF THE INVENTION

[0048] [DETAILED DESCRIPTION] Some detailed exemplary embodiments are disclosed herein. However, the specific structural and functional details disclosed herein are merely representative for explaining the exemplary embodiments. However, the exemplary embodiments can be embodied in many alternative forms and should not be construed as limited only to the exemplary embodiments described herein.

[0049] Accordingly, the exemplary embodiments are capable of various changes and alternative forms, and the exemplary embodiments are shown by way of example in the drawings and will be described in detail herein. However, it should be understood that there is no intention to limit the exemplary embodiments to the specific forms disclosed, and on the contrary, the exemplary embodiments are intended to cover all modifications, equivalents, and alternatives thereof. Like numbers refer to like elements throughout the description of the figures.

[0050] When an element or layer is said to be "on", "connected to", "coupled to", or "covering" another element or layer, it should be understood that it may be directly on, connected to, coupled to, or covering the other element or layer, or there may be intervening elements or layers. On the other hand, when an element is said to be "directly on", "directly connected to", or "directly coupled to" another element or layer, there are no intervening elements or layers. In this specification, the same number means the same element. In this specification, the term "and / or" includes any and all combinations or sub-combinations of one or more of the associated listed items.

[0051] In this specification, terms such as first, second, third, etc. may be used to describe various elements, regions, layers, and / or sections, but it should be understood that these elements, regions, layers, and / or sections should not be limited by these terms. These terms are only used to distinguish one element, region, layer, or section from another region, layer, or section. Thus, the first element, region, layer, or section described below could be referred to as the second element, region, layer, or section without departing from the teachings of the exemplary embodiments.

[0052] In this specification, for the sake of ease of explanation, spatially relative terms (such as "beneath", "below", "lower", "above", "upper", etc.) are used to describe the relationship between one element or function and another element or function as shown in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device during use and operation in addition to the orientation depicted in the figures. For example, if the device in the figure is turned over, an element described as "below" or "beneath" another element or feature will be oriented "above" the other element or feature. Thus, the term "below" can potentially encompass both the "above" and "below" orientations. Also, the device may be oriented in other directions (it may be rotated 90 degrees or oriented in other directions), and the spatially relative descriptors used in this specification are to be interpreted accordingly.

[0053] The terms used in this specification are for the purpose of describing various exemplary embodiments only and are not intended to limit the exemplary embodiments. The singular forms "a", "an", and "the" used in this specification are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "includes", "including", "comprises", and / or "comprising" used in this specification identify the presence of the described features, integers, steps, operations, and / or elements, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, and / or groups thereof.

[0054] In this specification, when the words "about" and "substantially" are used in relation to a numerical value, unless otherwise explicitly defined, the associated numerical value is intended to include a tolerance of ±10% around the recited numerical value.

[0055] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification shall have the same meaning as commonly understood by one of ordinary skill in the art to which the illustrated embodiments belong. Further, terms including those defined in commonly used dictionaries shall be interpreted as having a meaning that coincides with the meaning in the context of the relevant art, and it will be understood that they shall not be interpreted in an idealized or overly formal sense unless explicitly defined herein.

[0056] Hardware can be implemented using a processing circuit or a control circuit such as one or more processors, one or more CPUs (Central Processing Unit), one or more microcontrollers, one or more ALUs (Arithmetic Logic Unit), one or more DSPs (Digital Signal Processor), one or more microcomputers, one or more FPGAs (Field Programmable Gate Array), one or more SoCs (System-on-Chip), one or more programmable logic units (PLU), one or more microprocessors, one or more ASICs (Application Specific Integrated Circuit), or other devices that can execute in response to instructions in a defined manner (but not limited thereto).

In this embodiment, the first non-nicotine e-vaping section 12 may be disposed of after the depletion of the non-nicotine pre-vapor formulation 21 in the reservoir 62. In an exemplary embodiment, the first non-nicotine e-vaping section 12 is not disposable. In an exemplary embodiment, the non-nicotine e-vaping device 10 is a single section, and the structures of the power unit 14 and the first e-vaping section 12 are included in the single section. In an exemplary embodiment, the non-nicotine e-vaping device 10 comprises two or more sections.

[0072] FIG. 6 is an explanatory diagram of a cross-sectional view of the first non-nicotine e-vaping section 12 in an exemplary embodiment. The reference numbers described previously are generally not described again here for the sake of brevity. In an exemplary embodiment, the first housing 13 and the inner housing 33 surround the internal elements of the first non-nicotine e-vaping section 12. In an exemplary embodiment, the inner housing 33 defines at least one vent 30.

[0073] In one embodiment, the reservoir 62 is defined by a first reservoir housing (wall) 37 and a second reservoir housing (wall). In an exemplary embodiment, the first reservoir housing 37 includes a distal end portion 37a. The distal end portion 37a slides on the inner wall 39a of the second reservoir housing 39 to couple the first reservoir housing 37 and the second reservoir housing 39 through a friction fit connection. In an exemplary embodiment, the distal most end portion 45 of the second reservoir housing 39 contacts the ledge 47 of the first housing 13. Therein, the cutout region 43 holds the gasket 41 to form a liquid-tight seal between the first reservoir housing 37 and the second reservoir housing 39. In an exemplary embodiment, the reservoir 62 is defined by one continuous wall and / or housing, or two or more walls and / or housings. In an exemplary embodiment, the capacity of the reservoir 62 supplies a non-nicotine pre-vapor formulation 21 sufficient for the first non-nicotine e-vaping section 12 to produce approximately 10 to 20 draws before disposal. In an exemplary embodiment, the capacity of the reservoir 62 supplies a non-nicotine pre-vapor formulation 21 sufficient for the first non-nicotine e-vaping section 12 to produce 20 or more draws before disposal.

[0074] In an exemplary embodiment, the first non-nicotine e-vaping section 12 includes a channel 65 between a reservoir 62 and a chamber 72. In an exemplary embodiment, the first reservoir housing 37 defines one or more channels 65. In an exemplary embodiment, the channel 65 includes one or more first channels (first microchannels) 66. The first channel 66 is defined to be present between the reservoir 62 and the wick 64. In an exemplary embodiment, the one or more first channels 66 include only one channel, or two channels, or two or more channels. In an exemplary embodiment, the one or more first channels 66 enable the wick 64 to transport a flow 67 of the non-nicotine pre-vapor formulation 21 from the reservoir 62 to the wick 64, at least partially due to capillary forces generated by the wick 64. In an exemplary embodiment, the one or more first channels 66 enable the wick 64 to transport a flow 67 of the non-nicotine pre-vapor formulation 21 from the reservoir 62 to the wick 64, at least partially due to capillary forces generated by the small diameter of the one or more first channels 66. In an exemplary embodiment, the flow 67 of the non-nicotine pre-vapor formulation 21 is at least partially assisted by an air flow 69 entering the reservoir 62, as described below.

[0075] In an exemplary embodiment, the one or more first channels 66 include at least two channels. The at least two channels reduce the possibility that the one or more first channels 66 are partially or completely blocked by air bubbles. The air bubbles prevent or block the flow 67 of the non-nicotine pre-vapor formulation 21 from moving through the one or more first channels 66. In an exemplary embodiment, the wick 64 does not extend directly into the reservoir 62. In an exemplary embodiment, there is no capillary structure or wicking system between the reservoir 62 and the wick 64, or within the one or more first channels 66, and the sole transport mode of the non-nicotine pre-vapor formulation 21 from the reservoir 62 to the wick 64 is via exchange through the one or more first channels 66.

[0076] In an exemplary embodiment, the channel 65 includes one or more second channels (ventilation channels) 68. In an exemplary embodiment, the one or more second channels (second microchannels) 68 include only one channel, or two channels, or two or more channels. In an exemplary embodiment, the one or more second channels 68 are defined between the reservoir 62 and the chamber 72. In an exemplary embodiment, the one or more first channels 68 are disposed adjacent to the wick 64. In an exemplary embodiment, the one or more second channels 68 surround the wick 64 and / or the heater 60. In an exemplary embodiment, the one or more second channels 68 enable an air flow 69 to move from the chamber 72 to the reservoir 62 when the non-nicotine pre-vapor formulation 21 is discharged from the reservoir 62. In an exemplary embodiment, the air flow 69 is facilitated and / or assisted by the pressure generated within the chamber 72. The pressure is due to the inflowing air flow 31 and the flow of the non-nicotine vapor 73 passing through the chamber 72. In an exemplary embodiment, the air flow 69 is facilitated and / or assisted by a displacement (vacuum) force when the non-nicotine pre-vapor formulation 21 is displaced and consumed from the reservoir 62. In an exemplary embodiment, the one or more second channels 68 are defined between the reservoir 62 and the non-nicotine vapor channel 70, or another portion of the first non-nicotine e-vaping section 12 other than the chamber 72, or the ambient air.

[0077] In an exemplary embodiment, the first total flow channel cross-sectional area of the one or more first channels 66 is larger than the second total flow channel cross-sectional area of the one or more second channels 68. In an exemplary embodiment, the ratio of the first total flow channel cross-sectional area of the one or more first channels 66 to the second total flow channel cross-sectional area of the one or more second channels 68 is between about 10:1 and 4:1, or between about 9:1 and 5:1, or about 7:1. In an exemplary embodiment, the first total flow channel cross-sectional area of the one or more first channels 66 is between about 0.5 mm 2 and 1.5 mm 2 or between about 0.75 mm 2 and 1.25 mm 2between, or about 1 mm 2 In an exemplary embodiment, the total cross-sectional flow area of the one or more second channels 68 is from about 0.075 mm 2 to 0.225 mm 2 between, or about 0.1 mm 2 to 0.2 mm 2 between, or about 0.15 mm 2 In an exemplary embodiment, each of the one or more second channels 68 is small enough that the non-nicotine pre-vapor formulation 21 cannot pass through the one or more second channels 68. The size of each of the one or more second channels 68 depends on factors including the smoothness of each of the one or more second channels 68, the material defining the one or more second channels 68 (first reservoir housing 37), the surface tension of the non-nicotine pre-vapor formulation 21, etc. In an exemplary embodiment, assuming that the one or more second channels 68 include two channels, the cross-sectional flow area of each of the channels 68 is less than about 0.12 mm 2 or less than about 0.1 mm 2 or less than about 0.075 mm 2 Other ranges of values for the size of the one or more first channels 66 and the one or more second channels 68, and the ratio of the total cross-sectional flow area of the one or more first channels 66 to the one or more second channels 68 are contemplated.

[0078] In an exemplary embodiment, the wick 64 is on the wall 76 of the chamber 72. In an exemplary embodiment, the wall 76 is at least partially formed by the first reservoir housing 37. In an exemplary embodiment, the wick 64 is embedded in the wall 76 by the recess 78 of the wall 76. In an exemplary embodiment, the heater 60 heats the vicinity of the wick 64. That is, the heater 60 is close enough to the wick 64 to be able to at least partially vaporize the non-nicotine pre-vapor formulation 21 absorbed by the wick 64.

[0079] In an exemplary embodiment, the wick 64 is a thin pad. In an exemplary embodiment, the wick 64 is rectangular. In an exemplary embodiment, the wick 64 is square, circular, or another shape. In an exemplary embodiment, the wick 64 is sized to absorb a non-nicotine pre-vaporizer formulation 21 sufficient to produce one draw from the first non-nicotine e-vaping section 12. In an exemplary embodiment, the wick 64 is made of a porous material and / or an absorbent material having the ability to absorb the non-nicotine pre-vaporizer formulation 21. In an exemplary embodiment, the wick 64 is made of a fibrous material, filaments, including glass or ceramic filaments. In an exemplary embodiment, the wick 64 does not extend into the reservoir 62. In an exemplary embodiment, the wick 64 does not extend into one or more of the first channels 66. In an exemplary embodiment, the wick 64 is about 5mm 3 ~15mm 3 or about 7.5mm 3 ~12.5mm 3 or about 10mm 3 and holds the non-nicotine pre-vaporizer formulation 21. In an exemplary embodiment, the heater 60 and the wick 64 vaporize the non-nicotine pre-vaporizer formulation 21 in about 0.2 seconds.

[0080] In an exemplary embodiment, the heater 60 is in direct contact with the wick 64. In an exemplary embodiment, the heater 60 is on the surface of the wick 64. In an exemplary embodiment, the heater 60 comprises a flat surface 80, as described in more detail in FIG. 8. The flat surface 80 extends across at least a portion of the surface of the wick. In an exemplary embodiment, the flat surface 80 of the heater 60 faces the interior of the chamber 72. In an exemplary embodiment, the heater 60 is on the first side of the wick 64 opposite the second side of the wick 64. The second side of the wick 64 faces one or more of the first channels 66.

[0081] In an exemplary embodiment, at least one vent 30 includes an outlet (discharge end) 30a that guides the inflowing air stream 31 with the heater 60. In an exemplary embodiment, the outlet 30a is heated in the vicinity of the heater 60. In an exemplary embodiment, the outlet 30a is at a distance of about 1.0 mm to 2.0 mm from the heater 60, or at a distance of about 1.2 mm to 1.5 mm from the heater 60, or at a distance of about 1.3 mm from the heater 60. In an exemplary embodiment, the outlet 30a faces the heater 60. In an exemplary embodiment, the outlet 30a guides the inflowing air stream 31 at the central position 71 of the heater 60 (see FIG. 8). In an exemplary embodiment, the flow of the non-nicotine vapor 73 in the chamber 72 passes across at least a portion of the heater 60. In an exemplary embodiment, by facing the heater 60 to the outlet 30a, a turbulent state is generated in the heater 60. This enables a uniform mixing of the inflowing air stream 31 and the non-nicotine vapor from the heater 60 to occur. In an exemplary embodiment, the inflowing air stream 31 is also directed to, into, or near one or more second channels 68. This supplies an air pressure that further causes the inflowing air stream 31 to cause the air stream 69 to move from the chamber 72 to the reservoir 62. In an exemplary embodiment, the inflowing air stream 31 enters the chamber 72 in a first direction, and the chamber 72 allows the inflowing air stream 31 to flow away across the heater 60 in a second direction, and the first direction and the second direction are substantially perpendicular to each other. In an exemplary embodiment, the first direction is substantially perpendicular to the flat surface 80 of the heater 60 (see FIG. 8). In an exemplary embodiment, the second direction is substantially parallel to the flat surface 80 of the heater 60. In an exemplary embodiment, the cross-sectional area of the flow path of at least one vent 30 is adjusted to control the desired RTD of the first non-nicotine e-vaping section 12. In an exemplary embodiment, since the ambient air first passes through at least one air inlet 18 and at least one air inlet 36 before reaching at least one vent 30 instead, the inlet 30b of at least one vent 30 is not directly exposed to the ambient air during the operation of the non-nicotine e-vaping device 10.

[0082] In an exemplary embodiment, the non-nicotine vapor channel 70 is defined within the first non-nicotine e-vaping section 12. In an exemplary embodiment, the non-nicotine vapor channel is at least partially defined by the first housing 13, the first reservoir housing 37, and the second reservoir housing 39. In an exemplary embodiment, the non-nicotine vapor channel 70 is in fluid communication with the chambers 72 and one or more outlets 16, and the non-nicotine vapor channel 70 directs the flow of non-nicotine vapor 73 from the chamber 72 to the one or more outlets 16.

[0083] In an exemplary embodiment, the post 74 and the electrical connection 75 electrically connect the electrical connection 28 to the heater 60. [According to some embodiments, the first non-nicotine section and the general fluid flow through the device]

[0084] In an exemplary embodiment, air flow enters the non-nicotine e-vaping device 10 through at least one air inlet 18 (FIG. 4), passes through at least one air inlet 36, the internal space 29 (FIG. 5), and at least one vent 30, and enters the chamber 72. In the chamber 72, the air flow 31 entrains at least partially vaporized vapor from the heater 60. The resulting non-nicotine vapor 73 moves through the non-nicotine vapor channel 70 from the heater 60 before leaving the non-nicotine e-vaping device 10 through one or more outlets 16. In an exemplary embodiment, while the first non-nicotine e-vaping section 12 is in use, the flow 67 of the non-nicotine pre-vapor formulation moves from the reservoir 62 through one or more first channels 66 to the wick 64 and is at least partially vaporized by the heater 60, while the air flow 69 enters the reservoir 62 through one or more second channels 68. FIG. 7 is an explanatory diagram of another cross-sectional view (A-A perspective view of FIG. 6) of the first non-nicotine e-vaping section 12 according to an exemplary embodiment. The reference numerals previously described are generally not described again here for the sake of brevity. In an exemplary embodiment, the distal end 33a of the internal housing 33 at least partially defines the chamber 72. In an exemplary embodiment, the internal housing 33 fits into the first housing 13, and the first contact surface 77 of the internal housing 33 contacts the second contact surface 76 to ensure that the internal housing is correctly positioned within the first housing 13. In an exemplary embodiment, the internal housing 33 is held within the first housing 13 via a friction fit.

[0085] In an exemplary embodiment, the outlet 30a faces the heater 60 and the wick 64, and the outlet 30a is located at the substantial center of the central position 71 of the heater 60 (as shown in FIG. 8).

[0086] In an exemplary embodiment, the distal end 37a of the first reservoir housing 37 has an elliptical cross-section as shown in FIG. 7.

[0087] In an exemplary embodiment, the second reservoir housing 39 is adhesively connected inside the first housing 13 and the first reservoir housing 37 is adhesively connected to the second reservoir housing 39 through the application of an adhesive at one or more surface positions where the second reservoir housing 39 and the first housing 13 contact each other and at one or more surface positions where the first reservoir housing 37 and the second reservoir housing 39 contact each other. In an exemplary embodiment, using the application of an adhesive at the surface contact positions, the inner housing 33 is adhesively connected to the first reservoir housing and / or the first housing 13. In an exemplary embodiment, the adhesive (sealant) is a silicon-based adhesive or other suitable sealant that provides a liquid-tight and air-tight seal. In an exemplary embodiment, the first reservoir housing 37, the second reservoir housing 39, the inner housing 33 and the first housing 13 are held together via a friction (press) fit where no adhesive is used to assemble the first e-vaping section 12.

[0088] FIG. 8 is an explanatory diagram of a cross-sectional view (perspective view taken along line B-B in FIG. 7) of a first non-nicotine e-vaping section 12 according to an exemplary embodiment. In this figure, the elements along the wall 76 of the chamber 72 are shown in more detail. The reference numbers described previously are generally not described again here for the sake of brevity. In an exemplary embodiment, the heater 60 includes a heating element 61. In an exemplary embodiment, the heating element 61 is a flat metal structure. In an exemplary embodiment, the heating element 61 is a thin and / or linear structure. In an exemplary embodiment, the heating element 61 has a wave (e.g., sine wave) or "S" shape. In an exemplary embodiment, the heating element 61 has a shape that maximizes surface contact with the wick 64. In an exemplary embodiment, the heating element defines an opening 82 within the heating element 61 that exposes the surface area of the wick 64 to the interior of the chamber 72. In an exemplary embodiment, the heater 60, or the heating element 61 of the heater 60, forms a substantially flat surface 80. In an exemplary embodiment, the heater 60 is made of iron-aluminate (e.g., FeAl or Fe 3It is composed of (Al). In one embodiment, the heater 60 is in the form of a wire coil, a planar body, a ceramic body, a single wire, a cage of resistance wires, or other suitable form configured to vaporize the non-nicotine pre-vapor formulation 21. In at least one exemplary embodiment, the heater 60 is formed of any suitable electrically resistive material or materials. In an exemplary embodiment, the heater 60 is a ceramic heater having an electrical resistance layer on its outer surface.

[0089] In an exemplary embodiment, the central position 71 of the heater 60, which is the portion of the heater 60 facing the outlet 30a, comprises a flat surface 80. In an exemplary embodiment, the central position 71 of the heater 60 corresponds to the central region of the heater 60 and / or the heating element 61.

[0090] In an exemplary embodiment, the heater 60 comprises an electrical connection portion 84. In an exemplary embodiment, the electrical connection portion 84 is electrically connected to the power source 50. In an exemplary embodiment, the electrical connection portion 84 of the heater 60 is electrically connected to the electrical connection portion 75 and the post 74 of the first non-nicotine e-vaping section 12, and the post 74 is electrically connected to the electrical connection portion 28 of the first non-nicotine e-vaping section 12 and the electrical connection portion 44 of the power section 14 in sequence. In an exemplary embodiment, one of the electrical connection portions 44 is electrically connected to the power source 50, and the other of the electrical connection portions 44 is connected to the control circuit 55. Therefore, through the electrical connection portion 28 of the first non-nicotine e-vaping section 12 and via the post 74 and the electrical connection portion 75, the control circuit 55 of the control system 58 can selectively send a current from the power source 50 to the electrical connection portion 44 of the power section to energize the heater 60.

[0091] In an exemplary embodiment, one or more second channels 68 are on the side surface of the wick 64. In an exemplary embodiment, one or more second channels 68 are not covered by the wick 64, and one or more first channels 66 are covered by the wick 64. [Advantages of Some Exemplary Embodiments]

[0092] The advantages of some exemplary embodiments are as follows.

[0093] [A. Independence from gravity] Several factors, including the relatively small mass of the non-nicotine pre-vapor formulation, the small size of one or more first channels 66, and the geometric shape of the elements of the first non-nicotine e-vaping section 12, at least partially assist in making the non-nicotine e-vaping device 10 less or not dependent on gravity to operate the non-nicotine e-vaping device 10 to convey the non-nicotine pre-vapor formulation 21 to the wick 64 and the heater 60. That is, the orientation of the non-nicotine e-vaping device 10 does not affect or change the performance of the non-nicotine e-vaping device 10. These factors at least partially assist in reducing leakage and ensuring that a desired and uniform amount of the non-nicotine pre-vapor formulation 21 is applied to the wick and vaporized by the heater 60.

[0094] [B. Reduction in power source size] Several factors, including the relatively small mass of the non-nicotine pre-vapor formulation and the geometric shape of the elements of the first non-nicotine e-vaping section 12, enable a relatively small power source 50. This can assist in the charging method of the non-nicotine e-vaping device 10. [Embodiments of non-nicotine pre-vapor formulations]

[0095] In an exemplary embodiment, a flavoring (at least one flavorant) and / or a non-nicotine compound is included in the non-nicotine pre-vapor formulation 21. In an exemplary embodiment, the non-nicotine pre-vapor formulation 21 is a liquid, solid, dispersion, and / or gel formulation including, but not limited to, water, beads, solvents, active ingredients, ethanol, plant extracts, natural or artificial flavors, and / or at least one non-nicotine vapor-forming agent such as glycerin or propylene glycol.

[0096] Non-nicotine compounds do not contain nicotine. In an exemplary embodiment, the non-nicotine compound does not contain tobacco and is not a compound derived from tobacco. In an exemplary embodiment, the non-nicotine compound is cannabis or contains at least one cannabis-derived component. In an exemplary embodiment, the cannabis-derived component includes at least one of cannabis-derived cannabinoids (e.g., phytocannabinoids or cannabinoids synthesized by the cannabis plant), at least one cannabis-derived terpene, at least one cannabis-derived flavonoid, or a combination thereof.

[0097] In an exemplary embodiment, the non-nicotine compound is in the form of or contained in a solid, semi-solid, gel, hydrogel, or a combination thereof, and the non-nicotine compound is injected into, co-mixed with, or bound within the non-nicotine pre-vaporizer formulation 21. In an exemplary embodiment, the non-nicotine compound is in the form of or contained in a liquid or semi-liquid form including an extract, oil, tincture, suspension, dispersion, colloid, alcohol, a generally non-neutral (slightly acidic or slightly basic) solution, or a combination thereof, and the non-nicotine compound is injected into, incorporated into, or bound within the non-nicotine pre-vaporizer formulation 21. In an exemplary embodiment, the non-nicotine compound is a component of the non-nicotine pre-vaporizer formulation 21. In an exemplary embodiment, the non-nicotine pre-vaporizer formulation 21 is a dispersion, suspension, gel, hydrogel, colloid, or a combination thereof or a part thereof, and the non-nicotine compound is a component of the non-nicotine pre-vaporizer formulation 21.

[0098] In an exemplary embodiment, the non-nicotine compound undergoes a slow, natural decarboxylation reaction process over an extended period at a low temperature, including room temperature (72°F) and below. In an exemplary embodiment, when the non-nicotine compound is exposed to a high temperature in the range of about 175°F or higher for a certain period (several minutes or hours at a relatively low pressure such as 1 atmosphere), the non-nicotine compound may undergo a decarboxylation reaction of about 50% or more and a significantly increased decarboxylation reaction process. At even higher temperatures (about 240°F or higher), there is a possibility of a rapid or instantaneous decarboxylation reaction occurring at a high decarboxylation reaction rate (50% or more), but this may cause partial or complete degradation of some of the chemical properties of the non-nicotine compound.

[0099] In an exemplary embodiment, at least one non-nicotine vapor-forming agent of the non-nicotine pre-vapor formulation includes diols (such as propylene glycol and / or 1,3-propanediol), glycerin, and combinations or sub-combinations thereof. Various amounts of the non-nicotine vapor-forming agent may be used. For example, in some exemplary embodiments, the at least one non-nicotine vapor-forming agent is included in an amount ranging from about 20% by weight based on the weight of the non-nicotine pre-vapor formulation 21 to about 90% by weight based on the weight of the non-nicotine pre-vapor formulation 21 (e.g., the non-nicotine vapor-forming agent ranges from about 50% to about 80% by weight, or from about 55% to about 75% by weight, or from about 60% to about 70% by weight, etc.). As another example, in an exemplary embodiment, the non-nicotine pre-vapor formulation 21 includes a weight ratio of diol to glycerin in the range of about 1:4 to 4:1, and the diol is propylene glycol, or 1,3-propanediol, or a combination thereof. In an example of an embodiment, this ratio is about 3:2. Other amounts or ranges may also be possible.

[0100] In an exemplary embodiment, the non-nicotine pre-vaporizer formulation 21 contains water. Various amounts of water may be used. For example, in some exemplary embodiments, the water is in an amount ranging from about 5% by weight to about 40% by weight based on the weight of the non-nicotine pre-vaporizer formulation 21, or in an amount ranging from about 10% by weight to about 15% by weight based on the weight of the non-nicotine pre-vaporizer formulation 21. Other amounts or percentages may be used. For example, in an exemplary embodiment, the remaining portion of the non-nicotine pre-vaporizer formulation 21 that is not water (and not a non-nicotine compound and / or flavorant) is a non-nicotine vapor-forming agent (described above), the non-nicotine vapor-forming agent is 30% to 70% propylene glycol, and the balance of the non-nicotine vapor-forming agent is glycerin. Other amounts or ratios may be used.

[0101] In an exemplary embodiment, the non-nicotine pre-vaporizer formulation 21 contains at least one flavorant in an amount ranging from about 0.2 wt% to about 15 wt% (e.g., the flavorant may range from about 1 wt% to 12 wt%, or from about 2 wt% to 10 wt%, or from about 5 wt% to 8 wt%). In an exemplary embodiment, at least one flavorant contains a volatile cannabis flavor compound (flavonoid). In an exemplary embodiment, at least one flavorant contains a flavor compound instead of, or in addition to, a cannabis flavor compound. In an exemplary embodiment, at least one flavorant may be at least one of a natural flavorant, an artificial flavorant, or a combination of a natural flavorant and an artificial flavorant. For example, at least one flavorant may include menthol, wintergreen, peppermint, cinnamon, clove, combinations thereof, and / or extracts thereof. Further, flavors can be included to provide herb flavors, fruit flavors, nut flavors, liqueur flavors, roasted flavors, mint flavors, celery flavors, combinations thereof, and other desired flavors.

[0102] In an exemplary embodiment, the non-nicotine compound may be a natural component of a medicinal plant or a plant having a medically recognized therapeutic effect. The medicinal plant may be a cannabis plant, and the component may be at least one cannabis-derived component. Cannabinoids (phytocannabinoids) are an example of cannabis-derived components, and cannabinoids interact with receptors in the body to produce various effects. Therefore, cannabinoids are said to have various medicinal effects. Cannabis-derived materials may include materials of leaves and / or flowers of one or more cannabis plants, or extracts from one or more cannabis plants. In an exemplary embodiment, one or more cannabis plants contain Cannabis sativa, Cannabis indica, and Cannabis ruderalis. In some exemplary embodiments, the non-nicotine pre-vaporizer formulation 21 contains a mixture of cannabis and / or cannabis-derived components that are 60 to 80% (e.g., 70%) Cannabis sativa and 20 to 40% (e.g., 30%) Cannabis indica, or derived therefrom.

[0103] Examples of cannabis-derived cannabinoids include tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), cannabidiolic acid (CBDA), cannabidiol (CBD), cannabinol (CBN), cannabicyclol (CBL), cannabichromene (CBC), cannabigerol (CBG), and the like. Tetrahydrocannabinolic acid (THCA) is a precursor of tetrahydrocannabinol (THC), and cannabidiolic acid (CBDA) is a 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 exemplary embodiment, heat from the heater 60 may cause a decarboxylation reaction to convert tetrahydrocannabinolic acid (THCA) in the non-nicotine pre-vaper formulation 21 to tetrahydrocannabinol (THC), and / or may cause a decarboxylation reaction to convert cannabidiolic acid (CBDa) in the non-nicotine pre-vaper formulation 21 to cannabidiol (CBD).

[0104] When both tetrahydrocannabinolic acid (THCA) and tetrahydrocannabinol (THC) are present in the non-nicotine pre-vaporizer formulation 21, decarboxylation reaction and the resulting conversion cause a decrease in tetrahydrocannabinolic acid (THCA) and an increase in tetrahydrocannabinol (THC). At least 50% (e.g., at least 87%) of tetrahydrocannabinolic acid (THCA) may be converted to tetrahydrocannabinol (THC) via the decarboxylation reaction process during heating of the non-nicotine pre-vaporizer formulation 21 for the purpose of vaporization. Similarly, in an example where both cannabidiolic acid (CBDA) and cannabidiol (CBD) are present in the non-nicotine pre-vaporizer formulation 21, decarboxylation reaction and the resulting conversion cause a decrease in cannabidiolic acid (CBDA) and an increase in cannabidiol (CBD).
