Patent Description:
Some non-nicotine e-vaping devices include a first section coupled to a second section. The first section may include a wick and a heater. The wick is configured to move a non-nicotine pre-vapor formulation via capillary action and is positioned so as to extend into a reservoir and a vapor passage. The heater is in thermal contact with the wick and is configured to vaporize the non-nicotine pre-vapor formulation drawn via the wick into the vapor passage. The second section includes a power source configured to supply an electric current to the heater during vaping. The initiation of the operation of the non-nicotine e-vaping device may be achieved through manual- and/or puff-activation. <CIT> discloses an e-vapor apparatus including a pod assembly including a pre-vapor formulation compartment, a vapor channel traversing the pre-vapor formulation compartment, and a vaporizer, the pre-vapor formulation compartment configured to hold a pre-vapor formulation therein and in fluidic communication with the vaporizer during an operation of the e-vapor apparatus. The e-vapor apparatus further includes a dispensing body.

The present invention is defined herein in accordance with the appended claims.

According to independent claim <NUM>, a non-nicotine e-vaping device includes a non-nicotine pod assembly and a device body. The non-nicotine pod assembly has an upstream end and a downstream end and is configured to hold a non-nicotine pre-vapor formulation. The upstream end defines at least one upstream recess, and the downstream end defines at least one downstream recess. The device body defines a through hole configured to receive the non-nicotine pod assembly. The through hole includes an upstream sidewall and a downstream sidewall. The upstream sidewall includes at least one upstream protrusion, and the downstream sidewall includes at least one downstream protrusion. The at least one upstream protrusion and the at least one downstream protrusion are configured to engage with the at least one upstream recess and the at least one downstream recess, respectively, so as to facilitate a pivoting of the non-nicotine pod assembly into and retaining the non-nicotine pod assembly within the through hole of the device body. The at least one downstream protrusion of the device body includes two downstream protrusions disposed on adjacent corners of the downstream sidewall of the through hole.

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.

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.

It should be understood that when an element or layer is referred to as being "on," "connected to," "coupled to," "attached to," "adjacent to," "covering," etc. another element or layer, it may be directly on, connected to, coupled to, attached to, adjacent to, covering, etc. the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being "directly on," "directly connected to," "directly coupled to," etc. 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.

It should be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, regions, layers and/or sections, 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, a first element, region, layer, or section discussed below could be termed a second element, region, layer, or section without departing from the teachings of example embodiments.

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.

<FIG> is a front view of a non-nicotine e-vaping device according to an example embodiment. <FIG> is a side view of the non-nicotine e-vaping device of <FIG>. <FIG> is a rear view of the non-nicotine e-vaping device of <FIG>. Referring to <FIG>, a non-nicotine e-vaping device <NUM> includes a device body <NUM> that is configured to receive a non-nicotine pod assembly <NUM>. The non-nicotine pod assembly <NUM> is a modular article configured to hold a non-nicotine pre-vapor formulation. A non-nicotine pre-vapor formulation is a material or combination of materials that is devoid of nicotine and that may be transformed into a non-nicotine vapor. For example, the non-nicotine pre-vapor formulation may include a liquid, solid, and/or gel formulation. These may include, for example and without limitation, solutions and suspensions (e.g., emulsions) containing water, oil, beads, solvents, active ingredients, ethanol, plant extracts, non-nicotine compounds, natural or artificial flavors, vapor formers such as glycerin and propylene glycol, and/or any other ingredients that may be suitable for vaping. During vaping, the non-nicotine e-vaping device <NUM> is configured to heat the non-nicotine pre-vapor formulation to generate a non-nicotine vapor. Non-nicotine vapor, non-nicotine aerosol, and non-nicotine dispersion are used interchangeably and refer to the matter generated or outputted by the devices disclosed, claimed, and/or equivalents thereof, wherein such matter is devoid of nicotine.

As shown in <FIG> and <FIG>, the non-nicotine e-vaping device <NUM> extends in a longitudinal direction and has a length that is greater than its width. In addition, as shown in <FIG>, the length of the non-nicotine e-vaping device <NUM> is also greater than its thickness. Furthermore, the width of the non-nicotine e-vaping device <NUM> may be greater than its thickness. Assuming an x-y-z Cartesian coordinate system, the length of the non-nicotine e-vaping device <NUM> may be measured in the y-direction, the width may be measured in the x-direction, and the thickness may be measured in the z-direction. The non-nicotine e-vaping device <NUM> may have a substantially linear form with tapered ends based on its front, side, and rear views, although example embodiments are not limited thereto.

The device body <NUM> includes a front cover <NUM>, a frame <NUM>, and a rear cover <NUM>. The front cover <NUM>, the frame <NUM>, and the rear cover <NUM> form a device housing that encloses mechanical components, electronic components, and/or circuitry associated with the operation of the non-nicotine e-vaping device <NUM>. For instance, the device housing of the device body <NUM> may enclose a power source configured to power the non-nicotine e-vaping device <NUM>, which may include supplying an electric current to the non-nicotine pod assembly <NUM>. In addition, when assembled, the front cover <NUM>, the frame <NUM>, and the rear cover <NUM> may constitute a majority of the visible portion of the device body <NUM>. The device housing may be regarded as including all constituent parts of the device body <NUM> except for the mouthpiece <NUM>. Stated differently, the mouthpiece <NUM> and the device housing may be regarded as forming the device body <NUM>.

The front cover <NUM> (e.g., first cover) defines a primary opening configured to accommodate a bezel structure <NUM>. The primary opening may have a rounded rectangular shape, although other shapes are possible depending on the shape of the bezel structure <NUM>. The bezel structure <NUM> defines a through hole <NUM> configured to receive the non-nicotine pod assembly <NUM>. The through hole <NUM> is discussed herein in more detail in connection with, for instance, <FIG>.

The front cover <NUM> also defines a secondary opening configured to accommodate a light guide arrangement. The secondary opening may resemble a slot, although other shapes are possible depending on the shape of the light guide arrangement. In an example embodiment, the light guide arrangement includes a light guide housing <NUM> and a button housing <NUM>. The light guide housing <NUM> is configured to expose a light guide lens <NUM>, while the button housing <NUM> is configured to expose a first button lens <NUM> and a second button lens <NUM> (e.g., <FIG>). The first button lens <NUM> and an upstream portion of the button housing <NUM> may form a first button <NUM>. Similarly, the second button lens <NUM> and a downstream portion of the button housing <NUM> may form a second button <NUM>. The button housing <NUM> may be in a form of a single structure or two separate structures. With the latter form, the first button <NUM> and the second button <NUM> can move with a more independent feel when pressed.

The operation of the non-nicotine e-vaping device <NUM> may be controlled by the first button <NUM> and the second button <NUM>. For instance, the first button <NUM> may be a power button, and the second button <NUM> may be an intensity button. Although two buttons are shown in the drawings in connection with the light guide arrangement, it should be understood that more (or less) buttons may be provided depending on the available features and desired user interface.

The frame <NUM> (e.g., base frame) is the central support structure for the device body <NUM> (and the non-nicotine e-vaping device <NUM> as a whole). The frame <NUM> may be referred to as a chassis. The frame <NUM> includes a proximal end, a distal end, and a pair of side sections between the proximal end and the distal end. The proximal end and the distal end may also be referred to as the downstream end and the upstream end, respectively. As used herein, "proximal" (and, conversely, "distal") is in relation to an adult vaper during vaping, and "downstream" (and, conversely, "upstream") is in relation to a flow of the non-nicotine vapor. A bridging section may be provided between the opposing inner surfaces of the side sections (e.g., about midway along the length of the frame <NUM>) for additional strength and stability. The frame <NUM> may be integrally formed so as to be a monolithic structure.

With regard to material of construction, the frame <NUM> may be formed of an alloy or a plastic. The alloy (e.g., die cast grade, machinable grade) may be an aluminum (Al) alloy or a zinc (Zn) alloy. The plastic may be a polycarbonate (PC), an acrylonitrile butadiene styrene (ABS), or a combination thereof (PC/ABS). For instance, the polycarbonate may be LUPOY SC1004A. Furthermore, the frame <NUM> may be provided with a surface finish for functional and/or aesthetic reasons (e.g., to provide a premium appearance). In an example embodiment, the frame <NUM> (e.g., when formed of an aluminum alloy) may be anodized. In another embodiment, the frame <NUM> (e.g., when formed of a zinc alloy) may be coated with a hard enamel or painted. In another embodiment, the frame <NUM> (e.g., when formed of a polycarbonate) may be metallized. In yet another embodiment, the frame <NUM> (e.g., when formed of an acrylonitrile butadiene styrene) may be electroplated. It should be understood that the materials of construction with regard to the frame <NUM> may also be applicable to the front cover <NUM>, the rear cover <NUM>, and/or other appropriate parts of the non-nicotine e-vaping device <NUM>.

The rear cover <NUM> (e.g., second cover) also defines an opening configured to accommodate the bezel structure <NUM>. The opening may have a rounded rectangular shape, although other shapes are possible depending on the shape of the bezel structure <NUM>. In an example embodiment, the opening in the rear cover <NUM> is smaller than the primary opening in the front cover <NUM>. In addition, although not shown, it should be understood that a light guide arrangement (e.g., including buttons) may be provided on the rear of the non-nicotine e-vaping device <NUM> in addition to (or in lieu of) the light guide arrangement on the front of the non-nicotine e-vaping device <NUM>.

The front cover <NUM> and the rear cover <NUM> may be configured to engage with the frame <NUM> via a snap-fit arrangement. For instance, the front cover <NUM> and/or the rear cover <NUM> may include clips configured to interlock with corresponding mating members of the frame <NUM>. In a non-limiting embodiment, the clips may be in a form of tabs with orifices configured to receive the corresponding mating members (e.g., protrusions with beveled edges) of the frame <NUM>. Alternatively, the front cover <NUM> and/or the rear cover <NUM> may be configured to engage with the frame <NUM> via an interference fit (which may also be referred to as a press fit or friction fit). However, it should be understood that the front cover <NUM>, the frame <NUM>, and the rear cover <NUM> may be coupled via other suitable arrangements and techniques.

The device body <NUM> also includes a mouthpiece <NUM>. The mouthpiece <NUM> may be secured to the proximal end of the frame <NUM>. Additionally, as shown in <FIG>, in an example embodiment where the frame <NUM> is sandwiched between the front cover <NUM> and the rear cover <NUM>, the mouthpiece <NUM> may abut the front cover <NUM>, the frame <NUM>, and the rear cover <NUM>. Furthermore, in a non-limiting embodiment, the mouthpiece <NUM> may be joined with the device housing via a bayonet connection.

<FIG> is a proximal end view of the non-nicotine e-vaping device of <FIG>. Referring to <FIG>, the outlet face of the mouthpiece <NUM> defines a plurality of vapor outlets. In a non-limiting embodiment, the outlet face of the mouthpiece <NUM> may be elliptically-shaped. In addition, the outlet face of the mouthpiece <NUM> may include a first crossbar corresponding to a major axis of the elliptically-shaped outlet face and a second crossbar corresponding to a minor axis of the elliptically-shaped outlet face. Furthermore, the first crossbar and the second crossbar may intersect perpendicularly and be integrally formed parts of the mouthpiece <NUM>. Although the outlet face is shown as defining four vapor outlets, it should be understood that example embodiments are not limited thereto. For instance, the outlet face may define less than four (e.g., one, two) vapor outlets or more than four (e.g., six, eight) vapor outlets.

<FIG> is a distal end view of the non-nicotine e-vaping device of <FIG>. Referring to <FIG>, the distal end of the non-nicotine e-vaping device <NUM> includes a port <NUM>. The port <NUM> is configured to receive an electric current (e.g., via a USB/mini-USB cable) from an external power source so as to charge an internal power source within the non-nicotine e-vaping device <NUM>. In addition, the port <NUM> may also be configured to send data to and/or receive data (e.g., via a USB/mini-USB cable) from another non-nicotine e-vaping device or other electronic device (e.g., phone, tablet, computer). Furthermore, the non-nicotine e-vaping device <NUM> may be configured for wireless communication with another electronic device, such as a phone, via an application software (app) installed on that electronic device. In such an instance, an adult vaper may control or otherwise interface with the non-nicotine e-vaping device <NUM> (e.g., locate the non-nicotine e-vaping device, check usage information, change operating parameters) through the app.

<FIG> is a perspective view of the non-nicotine e-vaping device of <FIG>. <FIG> is an enlarged view of the pod inlet in <FIG>. Referring to <FIG>, and as briefly noted above, the non-nicotine e-vaping device <NUM> includes a non-nicotine pod assembly <NUM> configured to hold a non-nicotine pre-vapor formulation. The non-nicotine pod assembly <NUM> has an upstream end (which faces the light guide arrangement) and a downstream end (which faces the mouthpiece <NUM>). In a non-limiting embodiment, the upstream end is an opposing surface of the non-nicotine pod assembly <NUM> from the downstream end. The upstream end of the non-nicotine pod assembly <NUM> defines a pod inlet <NUM>. The device body <NUM> defines a through hole (e.g., through hole <NUM> in <FIG>) configured to receive the non-nicotine pod assembly <NUM>. In an example embodiment, the bezel structure <NUM> of the device body <NUM> defines the through hole and includes an upstream rim. As shown, particularly in <FIG>, the upstream rim of the bezel structure <NUM> is angled (e.g., dips inward) so as to expose the pod inlet <NUM> when the non-nicotine pod assembly <NUM> is seated within the through hole of the device body <NUM>.

For instance, rather than following the contour of the front cover <NUM> (so as to be relatively flush with the front face of the non-nicotine pod assembly <NUM> and, thus, obscure the pod inlet <NUM>), the upstream rim of the bezel structure <NUM> is in a form of a scoop configured to direct ambient air into the pod inlet <NUM>. This angled/scoop configuration (e.g., which may be curved) may help reduce or prevent the blockage of the air inlet (e.g., pod inlet <NUM>) of the non-nicotine e-vaping device <NUM>. The depth of the scoop may be such that less than half (e.g., less than a quarter) of the upstream end face of the non-nicotine pod assembly <NUM> is exposed. Additionally, in a non-limiting embodiment, the pod inlet <NUM> is in a form of a slot. Furthermore, if the device body <NUM> is regarded as extending in a first direction, then the slot may be regarded as extending in a second direction, wherein the second direction is transverse to the first direction.

<FIG> is a cross-sectional view of the non-nicotine e-vaping device of <FIG>. In <FIG>, the cross-section is taken along the longitudinal axis of the non-nicotine e-vaping device <NUM>. As shown, the device body <NUM> and the non-nicotine pod assembly <NUM> include mechanical components, electronic components, and/or circuitry associated with the operation of the non-nicotine e-vaping device <NUM>, which are discussed in more detail herein and/or are incorporated by reference herein. For instance, the non-nicotine pod assembly <NUM> may include mechanical components configured to actuate to release the non-nicotine pre-vapor formulation from a sealed reservoir within. The non-nicotine pod assembly <NUM> may also have mechanical aspects configured to engage with the device body <NUM> to facilitate the insertion and seating of the non-nicotine pod assembly <NUM>.

Additionally, the non-nicotine pod assembly <NUM> may be a "smart pod" that includes electronic components and/or circuitry configured to store, receive, and/or transmit information to/from the device body <NUM>. Such information may be used to authenticate the non-nicotine pod assembly <NUM> for use with the device body <NUM> (e.g., to prevent usage of an unapproved/counterfeit non-nicotine pod assembly). Furthermore, the information may be used to identify a type of the non-nicotine pod assembly <NUM> which is then correlated with a vaping profile based on the identified type. The vaping profile may be designed to set forth the general parameters for the heating of the non-nicotine pre-vapor formulation and may be subject to tuning, refining, or other adjustment by an adult vaper before and/or during vaping.

The non-nicotine pod assembly <NUM> may also communicate other information with the device body <NUM> that may be relevant to the operation of the non-nicotine e-vaping device <NUM>. Examples of relevant information may include a level of the non-nicotine pre-vapor formulation within the non-nicotine pod assembly <NUM> and/or a length of time that has passed since the non-nicotine pod assembly <NUM> was inserted into the device body <NUM> and activated. For instance, if the non-nicotine pod assembly <NUM> was inserted into the device body <NUM> and activated more than a certain period of time prior (e.g., more than <NUM> months ago), the non-nicotine e-vaping device <NUM> may not permit vaping, and the adult vaper may be prompted to change to a new non-nicotine pod assembly even though the non-nicotine pod assembly <NUM> still contains adequate levels of non-nicotine pre-vapor formulation.

The device body <NUM> may include mechanical components (e.g. complementary structures) configured to engage, hold, and/or activate the non-nicotine pod assembly <NUM>. In addition, the device body <NUM> may include electronic components and/or circuitry configured to receive an electric current to charge an internal power source (e.g., battery) which, in turn, is configured to supply power to the non-nicotine pod assembly <NUM> during vaping. Furthermore, the device body <NUM> may include electronic components and/or circuitry configured to communicate with the non-nicotine pod assembly <NUM>, a different non-nicotine e-vaping device, other electronic devices (e.g., phone, tablet, computer), and/or the adult vaper. The information being communicated may include pod-specific data, current vaping details, and/or past vaping patterns/history. The adult vaper may be notified of such communications with feedback that is haptic (e.g., vibrations), auditory (e.g., beeps), and/or visual (e.g., colored/blinking lights). The charging and/or communication of information may be performed with the port <NUM> (e.g., via a USB/mini-USB cable).

<FIG> is a perspective view of the device body of the non-nicotine e-vaping device of <FIG>. Referring to <FIG>, the bezel structure <NUM> of the device body <NUM> defines a through hole <NUM>. The through hole <NUM> is configured to receive a non-nicotine pod assembly <NUM>. To facilitate the insertion and seating of the non-nicotine pod assembly <NUM> within the through hole <NUM>, the upstream rim of the bezel structure <NUM> includes a first upstream protrusion 128a and a second upstream protrusion 128b. The through hole <NUM> may have a rectangular shape with rounded corners. In an example embodiment, the first upstream protrusion 128a and the second upstream protrusion 128b are integrally formed with the bezel structure <NUM> and located at the two rounded corners of the upstream rim.

The downstream sidewall of the bezel structure <NUM> may define a first downstream opening, a second downstream opening, and a third downstream opening. A retention structure including a first downstream protrusion 130a and a second downstream protrusion 130b is engaged with the bezel structure <NUM> such that the first downstream protrusion 130a and the second downstream protrusion 130b protrude through the first downstream opening and the second downstream opening, respectively, of the bezel structure <NUM> and into the through hole <NUM>. In addition, a distal end of the mouthpiece <NUM> extends through the third downstream opening of the bezel structure <NUM> and into the through hole <NUM> so as to be between the first downstream protrusion 130a and the second downstream protrusion 130b.

<FIG> is a front view of the device body of <FIG>. Referring to <FIG>, the device body <NUM> includes a device electrical connector <NUM> disposed at an upstream side of the through hole <NUM>. The device electrical connector <NUM> of the device body <NUM> is configured to electrically engage with a non-nicotine pod assembly <NUM> that is seated within the through hole <NUM>. As a result, power can be supplied from the device body <NUM> to the non-nicotine pod assembly <NUM> via the device electrical connector <NUM> during vaping. In addition, data can be sent to and/or received from the device body <NUM> and the non-nicotine pod assembly <NUM> via the device electrical connector <NUM>.

<FIG> is an enlarged perspective view of the through hole in <FIG>. Referring to <FIG>, the first upstream protrusion 128a, the second upstream protrusion 128b, the first downstream protrusion 130a, the second downstream protrusion 130b, and the distal end of the mouthpiece <NUM> protrude into the through hole <NUM>. In an example embodiment, the first upstream protrusion 128a and the second upstream protrusion 128b are stationary structures (e.g., stationary pivots), while the first downstream protrusion 130a and the second downstream protrusion 130b are tractable structures (e.g., retractable members). For instance, the first downstream protrusion 130a and the second downstream protrusion 130b may be configured (e.g., spring-loaded) to default to a protracted state while also configured to transition temporarily to a retracted state (and reversibly back to the protracted state) to facilitate an insertion of a non-nicotine pod assembly <NUM>.

In particular, when inserting a non-nicotine pod assembly <NUM> into the through hole <NUM> of the device body <NUM>, recesses at the upstream end face of the non-nicotine pod assembly <NUM> may be initially engaged with the first upstream protrusion 128a and the second upstream protrusion 128b followed by a pivoting of the non-nicotine pod assembly <NUM> (about the first upstream protrusion 128a and the second upstream protrusion 128b) until recesses at the downstream end face of the non-nicotine pod assembly <NUM> are engaged with the first downstream protrusion 130a and the second downstream protrusion 130b. In such an instance, the axis of rotation (during pivoting) of the non-nicotine pod assembly <NUM> may be orthogonal to the longitudinal axis of the device body <NUM>. In addition, the first downstream protrusion 130a and the second downstream protrusion 130b, which may be biased so as to be tractable, may retract when the non-nicotine pod assembly <NUM> is being pivoted into the through hole <NUM> and resiliently protract to engage recesses at the downstream end face of the non-nicotine pod assembly <NUM>. Furthermore, the engagement of the first downstream protrusion 130a and the second downstream protrusion 130b with recesses at the downstream end face of the non-nicotine pod assembly <NUM> may produce a haptic and/or auditory feedback (e.g., audible click) to notify an adult vaper that the non-nicotine pod assembly <NUM> is properly seated in the through hole <NUM> of the device body <NUM>.

<FIG> is an enlarged perspective view of the device electrical contacts in <FIG>. The device electrical contacts of the device body <NUM> are configured to engage with the pod electrical contacts of the non-nicotine pod assembly <NUM> when the non-nicotine pod assembly <NUM> is seated within the through hole <NUM> of the device body <NUM>. Referring to <FIG>, the device electrical contacts of the device body <NUM> include the device electrical connector <NUM>. The device electrical connector <NUM> includes power contacts and data contacts. The power contacts of the device electrical connector <NUM> are configured to supply power from the device body <NUM> to the non-nicotine pod assembly <NUM>. As illustrated, the power contacts of the device electrical connector <NUM> include a first pair of power contacts and a second pair of power contacts (which are positioned so as to be closer to the front cover <NUM> than the rear cover <NUM>). The first pair of power contacts (e.g., the pair adjacent to the first upstream protrusion 128a) may be a single integral structure that is distinct from the second pair of power contacts and that, when assembled, includes two projections that extend into the through hole <NUM>. Similarly, the second pair of power contacts (e.g., the pair adjacent to the second upstream protrusion 128b) may be a single integral structure that is distinct from the first pair of power contacts and that, when assembled, includes two projections that extend into the through hole <NUM>. The first pair of power contacts and the second pair of power contacts of the device electrical connector <NUM> may be tractably-mounted and biased so as to protract into the through hole <NUM> as a default and to retract (e.g., independently) from the through hole <NUM> when subjected to a force that overcomes the bias.

The data contacts of the device electrical connector <NUM> are configured to transmit data between a non-nicotine pod assembly <NUM> and the device body <NUM>. As illustrated, the data contacts of the device electrical connector <NUM> include a row of five projections (which are positioned so as to be closer to the rear cover <NUM> than the front cover <NUM>). The data contacts of the device electrical connector <NUM> may be distinct structures that, when assembled, extend into the through hole <NUM>. The data contacts of the device electrical connector <NUM> may also be tractably-mounted and biased (e.g., with springs) so as to protract into the through hole <NUM> as a default and to retract (e.g., independently) from the through hole <NUM> when subjected to a force that overcomes the bias. For instance, when a non-nicotine pod assembly <NUM> is inserted into the through hole <NUM> of the device body <NUM>, the pod electrical contacts of the non-nicotine pod assembly <NUM> will press against the corresponding device electrical contacts of the device body <NUM>. As a result, the power contacts and the data contacts of the device electrical connector <NUM> will be retracted (e.g., at least partially retracted) into the device body <NUM> but will continue to push against the corresponding pod electrical contacts due to their resilient arrangement, thereby helping to ensure a proper electrical connection between the device body <NUM> and the non-nicotine pod assembly <NUM>. Furthermore, such a connection may also be mechanically secure and have minimal contact resistance so as to allow power and/or signals between the device body <NUM> and the non-nicotine pod assembly <NUM> to be transferred and/or communicated reliably and accurately. While various aspects have been discussed in connection with the device electrical contacts of the device body <NUM>, it should be understood that example embodiments are not limited thereto and that other configurations may be utilized.

<FIG> is a partially exploded view involving the mouthpiece in <FIG>. Referring to <FIG>, the mouthpiece <NUM> is configured to engage with the device housing via a retention structure <NUM>. In an example embodiment, the retention structure <NUM> is situated so as to be primarily between the frame <NUM> and the bezel structure <NUM>. As shown, the retention structure <NUM> is disposed within the device housing such that the proximal end of the retention structure <NUM> extends through the proximal end of the frame <NUM>. The retention structure <NUM> may extend slightly beyond the proximal end of the frame <NUM> or be substantially even therewith. The proximal end of the retention structure <NUM> is configured to receive a distal end of the mouthpiece <NUM>. The proximal end of the retention structure <NUM> may be a female end, while the distal end of the mouthpiece may be a male end.

For instance, the mouthpiece <NUM> may be coupled (e.g., reversibly coupled) to the retention structure <NUM> with a bayonet connection. In such an instance, the female end of the retention structure <NUM> may define a pair of opposing L-shaped slots, while the male end of the mouthpiece <NUM> may have opposing radial members <NUM> (e.g., radial pins) configured to engage with the L-shaped slots of the retention structure <NUM>. Each of the L-shaped slots of the retention structure <NUM> may have a longitudinal portion and a circumferential portion. Optionally, the terminus of the circumferential portion may have a serif portion to help reduce or prevent the likelihood that that a radial member <NUM> of the mouthpiece <NUM> will inadvertently become disengaged. In a non-limiting embodiment, the longitudinal portions of the L-shaped slots extend in parallel and along a longitudinal axis of the device body <NUM>, while the circumferential portions of the L-shaped slots extend around the longitudinal axis (e.g., central axis) of the device body <NUM>. As a result, to couple the mouthpiece <NUM> to the device housing, the mouthpiece <NUM> shown in <FIG> is initially rotated <NUM> degrees to align the radial members <NUM> with the entrances to the longitudinal portions of the L-shaped slots of the retention structure <NUM>. The mouthpiece <NUM> is then pushed into the retention structure <NUM> such that the radial members <NUM> slide along the longitudinal portions of the L-shaped slots until the junction with each of the circumferential portions is reached. At this point, the mouthpiece <NUM> is then rotated such that the radial members <NUM> travel across the circumferential portions until the terminus of each is reached. Where a serif portion is present at each terminus, a haptic and/or auditory feedback (e.g., audible click) may be produced to notify an adult vaper that the mouthpiece <NUM> has been properly coupled to the device housing.

The mouthpiece <NUM> defines a vapor passage <NUM> through which non-nicotine vapor flows during vaping. The vapor passage <NUM> is in fluidic communication with the through hole <NUM> (which is where the non-nicotine pod assembly <NUM> is seated within the device body <NUM>). The proximal end of the vapor passage <NUM> may include a flared portion. In addition, the mouthpiece <NUM> may include an end cover <NUM>. The end cover <NUM> may taper from its distal end to its proximal end. The outlet face of the end cover <NUM> defines a plurality of vapor outlets. Although four vapor outlets are shown in the end cover <NUM>, it should be understood that example embodiments are not limited thereto.

<FIG> is a partially exploded view involving the bezel structure in <FIG>. <FIG> is an enlarged perspective view of the mouthpiece, springs, retention structure, and bezel structure in <FIG>. Referring to <FIG>, the bezel structure <NUM> includes an upstream sidewall and a downstream sidewall. The upstream sidewall of the bezel structure <NUM> defines a connector opening <NUM>. The connector opening <NUM> is configured to expose or receive the device electrical connector <NUM> of the device body <NUM>. The downstream sidewall of the bezel structure <NUM> defines a first downstream opening 148a, a second downstream opening 148b, and a third downstream opening 148c. The first downstream opening 148a and the second downstream opening 148b of the bezel structure <NUM> are configured to receive the first downstream protrusion 130a and the second downstream protrusion 130b, respectively, of the retention structure <NUM>. The third downstream opening 148c of the bezel structure <NUM> is configured to receive the distal end of the mouthpiece <NUM>.

As shown in <FIG>, the first downstream protrusion 130a and the second downstream protrusion 130b are on the concave side of the retention structure <NUM>. As shown in <FIG>, a first post 142a and a second post 142b are on the opposing convex side of the retention structure <NUM>. A first spring 144a and a second spring 144b are disposed on the first post 142a and the second post 142b, respectively. The first spring 144a and the second spring 144b are configured to bias the retention structure <NUM> against the bezel structure <NUM>.

When assembled, the bezel structure <NUM> may be secured to the frame <NUM> via a pair of tabs adjacent to the connector opening <NUM>. In addition, the retention structure <NUM> will abut the bezel structure <NUM> such that the first downstream protrusion 130a and the second downstream protrusion 130b extend through the first downstream opening 148a and the second downstream opening 148b, respectively. The mouthpiece <NUM> will be coupled to the retention structure <NUM> such that the distal end of the mouthpiece <NUM> extends through the retention structure <NUM> as well as the third downstream opening 148c of the bezel structure <NUM>. The first spring 144a and the second spring 144b will be between the frame <NUM> and the retention structure <NUM>.

When a non-nicotine pod assembly <NUM> is being inserted into the through hole <NUM> of the device body <NUM>, the downstream end of the non-nicotine pod assembly <NUM> will push against the first downstream protrusion 130a and the second downstream protrusion 130b of the retention structure <NUM>. As a result, the first downstream protrusion 130a and the second downstream protrusion 130b of the retention structure <NUM> will resiliently yield and retract from the through hole <NUM> of the device body <NUM> (by virtue of compression of the first spring 144a and the second spring 144b), thereby allowing the insertion of the non-nicotine pod assembly <NUM> to proceed. In an example embodiment, when the first downstream protrusion 130a and the second downstream protrusion 130b are fully retracted from the through hole <NUM> of the device body <NUM>, the displacement of the retention structure <NUM> may cause the ends of the first post 142a and the second post 142b to contact the inner end surface of the frame <NUM>. Furthermore, because the mouthpiece <NUM> is coupled to the retention structure <NUM>, the distal end of the mouthpiece <NUM> will retract from the through hole <NUM>, thus causing the proximal end of the mouthpiece <NUM> (e.g., visible portion including the end cover <NUM>) to also shift by a corresponding distance away from the device housing.

Once the non-nicotine pod assembly <NUM> is adequately inserted such that the first downstream recess and the second downstream recess of the non-nicotine pod assembly <NUM> reach a position that allows an engagement with the first downstream protrusion 130a and the second downstream protrusion 130b, respectively, the stored energy from the compression of the first spring 144a and the second spring 144b will cause the first downstream protrusion 130a and the second downstream protrusion 130b to resiliently protract and engage with the first downstream recess and the second downstream recess, respectively, of the non-nicotine pod assembly <NUM>. Furthermore, the engagement may produce a haptic and/or auditory feedback (e.g., audible click) to notify an adult vaper that the non-nicotine pod assembly <NUM> is properly seated within the through hole <NUM> of the device body <NUM>.

<FIG> is a partially exploded view involving the front cover, the frame, and the rear cover in <FIG>. Referring to <FIG>, various mechanical components, electronic components, and/or circuitry associated with the operation of the non-nicotine e-vaping device <NUM> may be secured to the frame <NUM>. The front cover <NUM> and the rear cover <NUM> may be configured to engage with the frame <NUM> via a snap-fit arrangement. In an example embodiment, the front cover <NUM> and the rear cover <NUM> include clips configured to interlock with corresponding mating members of the frame <NUM>. The clips may be in a form of tabs with orifices configured to receive the corresponding mating members (e.g., protrusions with beveled edges) of the frame <NUM>. In <FIG>, the front cover <NUM> has two rows with four clips each (for a total of eight clips for the front cover <NUM>). Similarly, the rear cover <NUM> has two rows with four clips each (for a total of eight clips for the rear cover <NUM>). The corresponding mating members of the frame <NUM> may be on the inner sidewalls of the frame <NUM>. As a result, the engaged clips and mating members may be hidden from view when the front cover <NUM> and the rear cover <NUM> are snapped together. Alternatively, the front cover <NUM> and/or the rear cover <NUM> may be configured to engage with the frame <NUM> via an interference fit. However, it should be understood that the front cover <NUM>, the frame <NUM>, and the rear cover <NUM> may be coupled via other suitable arrangements and techniques.

<FIG> is a perspective view of the non-nicotine pod assembly of the non-nicotine e-vaping device in <FIG>. <FIG> is another perspective view of the non-nicotine pod assembly of <FIG>. <FIG> is another perspective view of the non-nicotine pod assembly of <FIG>. Referring to <FIG>, the non-nicotine pod assembly <NUM> for the non-nicotine e-vaping device <NUM> includes a pod body configured to hold a non-nicotine pre-vapor formulation. The pod body has an upstream end and a downstream end. The upstream end of the pod body defines a cavity <NUM> (<FIG>). The downstream end of the pod body defines a pod outlet <NUM> that is in fluidic communication with the cavity <NUM> at the upstream end. A connector module <NUM> is configured to be seated within the cavity <NUM> of the pod body. The connector module <NUM> includes an external face and a side face. The external face of the connector module <NUM> forms an exterior of the pod body.

The external face of the connector module <NUM> defines a pod inlet <NUM>. The pod inlet <NUM> (through which air enters during vaping) is in fluidic communication with the pod outlet <NUM> (through which a non-nicotine vapor exits during vaping). The pod inlet <NUM> is shown in <FIG> as being in a form of a slot. However, it should be understood that example embodiments are not limited thereto and that other forms are possible. When the connector module <NUM> is seated within the cavity <NUM> of the pod body, the external face of the connector module <NUM> remains visible, while the side face of the connector module <NUM> becomes mostly obscured so as to be only partially viewable through the pod inlet <NUM> based on a given angle.

The external face of the connector module <NUM> includes at least one electrical contact. The at least one electrical contact may include a plurality of power contacts. For instance, the plurality of power contacts may include a first power contact 324a and a second power contact 324b. The first power contact 324a of the non-nicotine pod assembly <NUM> is configured to electrically connect with the first pair of power contacts (e.g., the pair adjacent to the first upstream protrusion 128a in <FIG>) of the device electrical connector <NUM> of the device body <NUM>. Similarly, the second power contact 324b of the non-nicotine pod assembly <NUM> is configured to electrically connect with the second pair of power contacts (e.g., the pair adjacent to the second upstream protrusion 128b in <FIG>) of the device electrical connector <NUM> of the device body <NUM>. In addition, the at least one electrical contact of the non-nicotine pod assembly <NUM> includes a plurality of data contacts <NUM>. The plurality of data contacts <NUM> of the non-nicotine pod assembly <NUM> are configured to electrically connect with the data contacts of the device electrical connector <NUM> (e.g., row of five projections in <FIG>). While two power contacts and five data contacts are shown in connection with the non-nicotine pod assembly <NUM>, it should be understood that other variations are possible depending on the design of the device body <NUM>.

In an example embodiment, the non-nicotine pod assembly <NUM> includes a front face, a rear face opposite the front face, a first side face between the front face and the rear face, a second side face opposite the first side face, an upstream end face, and a downstream end face opposite the upstream end face. The corners of the side and end faces (e.g., corner of the first side face and the upstream end face, corner of upstream end face and the second side face, corner of the second side face and the downstream end face, corner of the downstream end face and the first side face) may be rounded. However, in some instances, the corners may be angular. In addition, the peripheral edge of the front face may be in a form of a ledge. The external face of the connector module <NUM> may be regarded as being part of the upstream end face of the non-nicotine pod assembly <NUM>. The front face of the non-nicotine pod assembly <NUM> may be wider and longer than the rear face. In such an instance, the first side face and the second side face may be angled inwards towards each other. The upstream end face and the downstream end face may also be angled inwards towards each other. Because of the angled faces, the insertion of the non-nicotine pod assembly <NUM> will be unidirectional (e.g., from the front side (side associated with the front cover <NUM>) of the device body <NUM>). As a result, the possibility that the non-nicotine pod assembly <NUM> will be improperly inserted into the device body <NUM> can be reduced or prevented.

As illustrated, the pod body of the non-nicotine pod assembly <NUM> includes a first housing section <NUM> and a second housing section <NUM>. The first housing section <NUM> has a downstream end defining the pod outlet <NUM>. The rim of the pod outlet <NUM> may optionally be a sunken or indented region. In such an instance, this region may resemble a cove, wherein the side of the rim adjacent to the rear face of the non-nicotine pod assembly <NUM> may be open, while the side of the rim adjacent to the front face may be surrounded by a raised portion of the downstream end of the first housing section <NUM>. The raised portion may function as a stopper for the distal end of the mouthpiece <NUM>. As a result, this configuration for the pod outlet <NUM> may facilitate the receiving and aligning of the distal end of the mouthpiece <NUM> (e.g., <FIG>) via the open side of the rim and its subsequent seating against the raised portion of the downstream end of the first housing section <NUM>. In a non-limiting embodiment, the distal end of the mouthpiece <NUM> may also include (or be formed of) a resilient material to help create a seal around the pod outlet <NUM> when the non-nicotine pod assembly <NUM> is properly inserted within the through hole <NUM> of the device body <NUM>.

The downstream end of the first housing section <NUM> additionally defines at least one downstream recess. In an example embodiment, the at least one downstream recess is in a form of a first downstream recess 306a and a second downstream recess 306b. The pod outlet <NUM> may be between the first downstream recess 306a and the second downstream recess 306b. The first downstream recess 306a and the second downstream recess 306b are configured to engage with the first downstream protrusion 130a and the second downstream protrusion 130b, respectively, of the device body <NUM>. As shown in <FIG>, the first downstream protrusion 130a and the second downstream protrusion 130b of the device body <NUM> may be disposed on adjacent corners of the downstream sidewall of the through hole <NUM>. The first downstream recess 306a and the second downstream recess 306b may each be in a form of a V-shaped notch. In such an instance, each of the first downstream protrusion 130a and the second downstream protrusion 130b of the device body <NUM> may be in a form of a wedge-shaped structure configured to engage with a corresponding V-shaped notch of the first downstream recess 306a and the second downstream recess 306b. The first downstream recess 306a may abut the corner of the downstream end face and the first side face, while the second downstream recess 306b may abut the corner of the downstream end face and the second side face. As a result, the edges of the first downstream recess 306a and the second downstream recess 306b adjacent to the first side face and the second side face, respectively, may be open. In such an instance, as shown in <FIG>, each of the first downstream recess 306a and the second downstream recess 306b may be a <NUM>-sided recess.

The second housing section <NUM> has an upstream end defining the cavity <NUM> (<FIG>). The cavity <NUM> is configured to receive the connector module <NUM> (<FIG>). In addition, the upstream end of the second housing section <NUM> defines at least one upstream recess. In an example embodiment, the at least one upstream recess is in a form of a first upstream recess 312a and a second upstream recess 312b. The pod inlet <NUM> may be between the first upstream recess 312a and the second upstream recess 312b. The first upstream recess 312a and the second upstream recess 312b are configured to engage with the first upstream protrusion 128a and the second upstream protrusion 128b, respectively, of the device body <NUM>. As shown in <FIG>, the first upstream protrusion 128a and the second upstream protrusion 128b of the device body <NUM> may be disposed on adjacent corners of the upstream sidewall of the through hole <NUM>. A depth of each of the first upstream recess 312a and the second upstream recess 312b may be greater than a depth of each of the first downstream recess 306a and the second downstream recess 306b. A terminus of each of the first upstream recess 312a and the second upstream recess 312b may also be more rounded than a terminus of each of the first downstream recess 306a and the second downstream recess 306b. For instance, the first upstream recess 312a and the second upstream recess 312b may each be in a form of a U-shaped indentation. In such an instance, each of the first upstream protrusion 128a and the second upstream protrusion 128b of the device body <NUM> may be in a form of a rounded knob configured to engage with a corresponding U-shaped indentation of the first upstream recess 312a and the second upstream recess 312b. The first upstream recess 312a may abut the corner of the upstream end face and the first side face, while the second upstream recess 312b may abut the corner of the upstream end face and the second side face. As a result, the edges of the first upstream recess 312a and the second upstream recess 312b adjacent to the first side face and the second side face, respectively, may be open.

The first housing section <NUM> may define a reservoir within configured to hold the non-nicotine pre-vapor formulation. The reservoir may be configured to hermetically seal the non-nicotine pre-vapor formulation until an activation of the non-nicotine pod assembly <NUM> to release the non-nicotine pre-vapor formulation from the reservoir. As a result of the hermetic seal, the non-nicotine pre-vapor formulation may be isolated from the environment as well as the internal elements of the non-nicotine pod assembly <NUM> that may potentially react with the non-nicotine pre-vapor formulation, thereby reducing or preventing the possibility of adverse effects to the shelf-life and/or sensorial characteristics (e.g., flavor) of the non-nicotine pre-vapor formulation. The second housing section <NUM> may contain structures configured to activate the non-nicotine pod assembly <NUM> and to receive and heat the non-nicotine pre-vapor formulation released from the reservoir after the activation.

The non-nicotine pod assembly <NUM> may be activated manually by an adult vaper prior to the insertion of the non-nicotine pod assembly <NUM> into the device body <NUM>. Alternatively, the non-nicotine pod assembly <NUM> may be activated as part of the insertion of the non-nicotine pod assembly <NUM> into the device body <NUM>. In an example embodiment, the second housing section <NUM> of the pod body includes a perforator configured to release the non-nicotine pre-vapor formulation from the reservoir during the activation of the non-nicotine pod assembly <NUM>. The perforator may be in a form of a first activation pin 314a and a second activation pin 314b, which will be discussed in more detail herein.

To activate the non-nicotine pod assembly <NUM> manually, an adult vaper may press the first activation pin 314a and the second activation pin 314b inward (e.g., simultaneously or sequentially) prior to inserting the non-nicotine pod assembly <NUM> into the through hole <NUM> of the device body <NUM>. For instance, the first activation pin 314a and the second activation pin 314b may be manually pressed until the ends thereof are substantially even with the upstream end face of the non-nicotine pod assembly <NUM>. In an example embodiment, the inward movement of the first activation pin 314a and the second activation pin 314b causes a seal of the reservoir to be punctured or otherwise compromised so as to release the non-nicotine pre-vapor formulation therefrom.

Alternatively, to activate the non-nicotine pod assembly <NUM> as part of the insertion of the non-nicotine pod assembly <NUM> into the device body <NUM>, the non-nicotine pod assembly <NUM> is initially positioned such that the first upstream recess 312a and the second upstream recess 312b are engaged with the first upstream protrusion 128a and the second upstream protrusion 128b, respectively (e.g., upstream engagement). Because each of the first upstream protrusion 128a and the second upstream protrusion 128b of the device body <NUM> may be in a form of a rounded knob configured to engage with a corresponding U-shaped indentation of the first upstream recess 312a and the second upstream recess 312b, the non-nicotine pod assembly <NUM> may be subsequently pivoted with relative ease about the first upstream protrusion 128a and the second upstream protrusion 128b and into the through hole <NUM> of the device body <NUM>.

With regard to the pivoting of the non-nicotine pod assembly <NUM>, the axis of rotation may be regarded as extending through the first upstream protrusion 128a and the second upstream protrusion 128b and oriented orthogonally to a longitudinal axis of the device body <NUM>. During the initial positioning and subsequent pivoting of the non-nicotine pod assembly <NUM>, the first activation pin 314a and the second activation pin 314b will come into contact with the upstream sidewall of the through hole <NUM> and transition from a protracted state to a retracted state as the first activation pin 314a and the second activation pin 314b are pushed (e.g., simultaneously) into the second housing section <NUM> as the non-nicotine pod assembly <NUM> progresses into the through hole <NUM>. When the downstream end of the non-nicotine pod assembly <NUM> reaches the vicinity of the downstream sidewall of the through hole <NUM> and comes into contact with the first downstream protrusion 130a and the second downstream protrusion 130b, the first downstream protrusion 130a and the second downstream protrusion 130b will retract and then resiliently protract (e.g., spring back) when the positioning of the non-nicotine pod assembly <NUM> allows the first downstream protrusion 130a and the second downstream protrusion 130b of the device body <NUM> to engage with the first downstream recess 306a and the second downstream recess 306b, respectively, of the non-nicotine pod assembly <NUM> (e.g., downstream engagement).

As noted supra, according to an example embodiment, the mouthpiece <NUM> is secured to the retention structure <NUM> (of which the first downstream protrusion 130a and the second downstream protrusion 130b are a part). In such an instance, the retraction of the first downstream protrusion 130a and the second downstream protrusion 130b from the through hole <NUM> will cause a simultaneous shift of the mouthpiece <NUM> by a corresponding distance in the same direction (e.g., downstream direction). Conversely, the mouthpiece <NUM> will spring back simultaneously with the first downstream protrusion 130a and the second downstream protrusion 130b when the non-nicotine pod assembly <NUM> has been sufficiently inserted to facilitate downstream engagement. In addition to the resilient engagement by the first downstream protrusion 130a and the second downstream protrusion 130b, the distal end of the mouthpiece <NUM> is configured to also be biased against the non-nicotine pod assembly <NUM> (and aligned with the pod outlet <NUM> so as to form a relatively vapor-tight seal) when the non-nicotine pod assembly <NUM> is properly seated within the through hole <NUM> of the device body <NUM>.

Furthermore, the downstream engagement may produce an audible click and/or a haptic feedback to indicate that the non-nicotine pod assembly <NUM> is properly seated within the through hole <NUM> of the device body <NUM>. When properly seated, the non-nicotine pod assembly <NUM> will be connected to the device body <NUM> mechanically, electrically, and fluidically. Although the non-limiting embodiments herein describe the upstream engagement of the non-nicotine pod assembly <NUM> as occurring before the downstream engagement, it should be understood that the pertinent mating, activation, and/or electrical arrangements may be reversed such that the downstream engagement occurs before the upstream engagement. The engagement of the non-nicotine pod assembly <NUM> with the device body <NUM> as well as other aspects of the non-nicotine e-vaping device <NUM> may also be as described in <CIT>, titled "Non-nicotine Pod Assemblies And Non-nicotine E-vaping Devices" (Atty. No. 24000NV-<NUM>-US), filed concurrently herewith, the entire contents of which is incorporated herein by reference.

<FIG> is a perspective view of the non-nicotine pod assembly of <FIG> without the connector module. Referring to <FIG>, the upstream end of the second housing section <NUM> defines a cavity <NUM>. As noted supra, the cavity <NUM> is configured to receive the connector module <NUM> (e.g., via interference fit). In an example embodiment, the cavity <NUM> is situated between the first upstream recess 312a and the second upstream recess 312b and also situated between the first activation pin 314a and the second activation pin 314b. In the absence of the connector module <NUM>, an insert <NUM> (<FIG>) and an absorbent material <NUM> (<FIG>) are visible through a recessed opening in the cavity <NUM>. The insert <NUM> is configured to retain the absorbent material <NUM>. The absorbent material <NUM> is configured to absorb and hold a quantity of the non-nicotine pre-vapor formulation released from the reservoir when the non-nicotine pod assembly <NUM> is activated. The insert <NUM> and the absorbent material <NUM> will be discussed in more detail herein.

<FIG> is a perspective view of the connector module in <FIG>. <FIG> is another perspective view of the connector module of <FIG>. Referring to <FIG>, the general framework of the connector module <NUM> includes a module housing <NUM> and a face plate <NUM>. In addition, the connector module <NUM> has a plurality of faces, including an external face and a side face, wherein the external face is adjacent to the side face. In an example embodiment, the external face of the connector module <NUM> is composed of upstream surfaces of the face plate <NUM>, the first power contact 324a, the second power contact 324b, and the data contacts <NUM>. The side face of the connector module <NUM> is part of the module housing <NUM>. The side face of the connector module <NUM> defines a first module inlet <NUM> and a second module inlet <NUM>. Furthermore, the two lateral faces adjacent to the side face (which are also part of the module housing <NUM>) may include rib structures (e.g., crush ribs) configured to facilitate an interference fit when the connector module <NUM> is seated within the cavity <NUM> of the pod body. For instance, each of the two lateral faces may include a pair of rib structures that taper away from the face plate <NUM>. As a result, the module housing <NUM> will encounter increasing resistance via the friction of the rib structures against the lateral walls of the cavity <NUM> as the connector module <NUM> is pressed into the cavity <NUM> of the pod body. When the connector module <NUM> is seated within the cavity <NUM>, the face plate <NUM> may be substantially flush with the upstream end of the second housing section <NUM>. Also, the side face (which defines the first module inlet <NUM> and the second module inlet <NUM>) of the connector module <NUM> will be facing a sidewall of the cavity <NUM>.

The face plate <NUM> of the connector module <NUM> may have a grooved edge <NUM> that, in combination with a corresponding side surface of the cavity <NUM>, defines the pod inlet <NUM>. However, it should be understood that example embodiments are not limited thereto. For instance, the face plate <NUM> of the connector module <NUM> may be alternatively configured so as to entirely define the pod inlet <NUM>. The side face (which defines the first module inlet <NUM> and the second module inlet <NUM>) of the connector module <NUM> and the sidewall of the cavity <NUM> (which faces the side face) define an intermediate space in between. The intermediate space is downstream from the pod inlet <NUM> and upstream from the first module inlet <NUM> and the second module inlet <NUM>. Thus, in an example embodiment, the pod inlet <NUM> is in fluidic communication with both the first module inlet <NUM> and the second module inlet <NUM> via the intermediate space. The first module inlet <NUM> may be larger than the second module inlet <NUM>. In such an instance, when incoming air is received by the pod inlet <NUM> during vaping, the first module inlet <NUM> may receive a primary flow (e.g., larger flow) of the incoming air, while the second module inlet <NUM> may receive a secondary flow (e.g., smaller flow) of the incoming air.

As shown in <FIG>, the connector module <NUM> includes a wick <NUM> that is configured to transfer a non-nicotine pre-vapor formulation to a heater <NUM>. The heater <NUM> is configured to heat the non-nicotine pre-vapor formulation during vaping to generate a non-nicotine vapor. The heater <NUM> may be mounted in the connector module <NUM> via a contact core <NUM>. The heater <NUM> is electrically connected to at least one electrical contact of the connector module <NUM>. For instance, one end (e.g., first end) of the heater <NUM> may be connected to the first power contact 324a, while the other end (e.g., second end) of the heater <NUM> may be connected to the second power contact 324b. In an example embodiment, the heater <NUM> includes a folded heating element. In such an instance, the wick <NUM> may have a planar form configured to be held by the folded heating element. When the connector module <NUM> is seated within the cavity <NUM> of the pod body, the wick <NUM> is configured to be in fluidic communication with the absorbent material <NUM> such that the non-nicotine pre-vapor formulation that will be in the absorbent material <NUM> (when the non-nicotine pod assembly <NUM> is activated) will be transferred to the wick <NUM> via capillary action.

<FIG> is an exploded view involving the wick, heater, electrical leads, and contact core in <FIG>. Referring to <FIG>, the wick <NUM> may be a fibrous pad or other structure with pores/interstices designed for capillary action. In addition, the wick <NUM> may have a shape of an irregular hexagon, although example embodiments are not limited thereto. The wick <NUM> may be fabricated into the hexagonal shape or cut from a larger sheet of material into this shape. Because the lower section of the wick <NUM> is tapered towards the winding section of the heater <NUM>, the likelihood of the non-nicotine pre-vapor formulation being in a part of the wick <NUM> that continuously evades vaporization (due to its distance from the heater <NUM>) can be reduced or avoided.

In an example embodiment, the heater <NUM> is configured to undergo Joule heating (which is also known as ohmic/resistive heating) upon the application of an electric current thereto. Stated in more detail, the heater <NUM> may be formed of one or more conductors (resistive materials) and configured to produce heat when an electric current passes therethrough. The electric current may be supplied from a power source (e.g., battery) within the device body <NUM> and conveyed to the heater <NUM> via the first power contact 324a and the first electrical lead 340a (or via the second power contact 324b and the second electrical lead 340b).

Suitable conductors (resistive materials) for the heater <NUM> include an iron-based alloy (e.g., stainless steel) and/or a nickel-based alloy (e.g., nichrome). The heater <NUM> may be fabricated from a conductive sheet (e.g., metal, alloy) that is stamped to cut a winding pattern therefrom. The winding pattern may have curved segments alternately arranged with horizontal segments so as to allow the horizontal segments to zigzag back and forth while extending in parallel. In addition, a width of each of the horizontal segments of the winding pattern may be substantially equal to a spacing between adjacent horizontal segments of the winding pattern, although example embodiments are not limited thereto. To obtain the form of the heater <NUM> shown in the drawings, the winding pattern may be folded so as to grip the wick <NUM>.

The heater <NUM> may be secured to the contact core <NUM> with a first electrical lead 340a and a second electrical lead 340b. The contact core <NUM> is formed of an insulating material and configured to electrically isolate the first electrical lead 340a from the second electrical lead 340b. In an example embodiment, the first electrical lead 340a and the second electrical lead 340b each define a female aperture that is configured to engage with corresponding male members of the contact core <NUM>. Once engaged, the first end and the second end of the heater <NUM> may be secured (e.g., welded, soldered, brazed) to the first electrical lead 340a and the second electrical lead 340b, respectively. The contact core <NUM> may then be seated within a corresponding socket in the module housing <NUM> (e.g., via interference fit). Upon completion of the assembly of the connector module <NUM>, the first electrical lead 340a will electrically connect a first end of the heater <NUM> with the first power contact 324a, while the second electrical lead 340b will electrically connect a second end of the heater <NUM> with the second power contact 324b. The heater and associated structures are discussed in more detail in <CIT>, the entire contents of which is incorporated herein by reference.

<FIG> is an exploded view involving the first housing section of the non-nicotine pod assembly of <FIG>. Referring to <FIG>, the first housing section <NUM> includes a vapor channel <NUM>. The vapor channel <NUM> is configured to receive a non-nicotine vapor generated by the heater <NUM> and is in fluidic communication with the pod outlet <NUM>. In an example embodiment, the vapor channel <NUM> may gradually increase in size (e.g., diameter) as it extends towards the pod outlet <NUM>. In addition, the vapor channel <NUM> may be integrally formed with the first housing section <NUM>. A wrap <NUM>, an insert <NUM>, and a seal <NUM> are disposed at an upstream end of the first housing section <NUM> to define the reservoir of the non-nicotine pod assembly <NUM>. For instance, the wrap <NUM> may be disposed on the rim of the first housing section <NUM>. The insert <NUM> may be seated within the first housing section <NUM> such that the peripheral surface of the insert <NUM> engages with the inner surface of the first housing section <NUM> along the rim (e.g., via interference fit) such that the interface of the peripheral surface of the insert <NUM> and the inner surface of the first housing section <NUM> is fluid-tight (e.g., liquid-tight and/or air-tight). Furthermore, the seal <NUM> is attached to the upstream side of the insert <NUM> to close off the reservoir outlets in the insert <NUM> so as to provide a fluid-tight (e.g., liquid-tight and/or air-tight) containment of the non-nicotine pre-vapor formulation in the reservoir.

In an example embodiment, the insert <NUM> includes a holder portion that projects from the upstream side (as shown in <FIG>) and a connector portion that projects from the downstream side (hidden from view in <FIG>). The holder portion of the insert <NUM> is configured to hold the absorbent material <NUM>, while the connector portion of the insert <NUM> is configured to engage with the vapor channel <NUM> of the first housing section <NUM>. The connector portion of the insert <NUM> may be configured to be seated within the vapor channel <NUM> and, thus, engage the interior of the vapor channel <NUM>. Alternatively, the connector portion of the insert <NUM> may be configured to receive the vapor channel <NUM> and, thus, engage with the exterior of the vapor channel <NUM>. The insert <NUM> also defines reservoir outlets through which the non-nicotine pre-vapor formulation flows when the seal <NUM> is punctured (as shown in <FIG>) during the activation of the non-nicotine pod assembly <NUM>. The holder portion and the connector portion of the insert <NUM> may be between the reservoir outlets (e.g., first and second reservoir outlets), although example embodiments are not limited thereto. Furthermore, the insert <NUM> defines a vapor conduit extending through the holder portion and the connector portion. As a result, when the insert <NUM> is seated within the first housing section <NUM>, the vapor conduit of the insert <NUM> will be aligned with and in fluidic communication with the vapor channel <NUM> so as to form a continuous path through the reservoir to the pod outlet <NUM> for the non-nicotine vapor generated by the heater <NUM> during vaping.

The seal <NUM> is attached to the upstream side of the insert <NUM> so as to cover the reservoir outlets in the insert <NUM>. In an example embodiment, the seal <NUM> defines an opening (e.g., central opening) configured to provide the pertinent clearance to accommodate the holder portion (that projects from the upstream side of the insert <NUM>) when the seal <NUM> is attached to the insert <NUM>. In <FIG>, it should be understood that the seal <NUM> is shown in a punctured state. In particular, when punctured by the first activation pin 314a and the second activation pin 314b of the non-nicotine pod assembly <NUM>, the two punctured sections of the seal <NUM> will be pushed into the reservoir as flaps (as shown in <FIG>), thus creating two punctured openings (e.g., one on each side of the central opening) in the seal <NUM>. The size and shape of the punctured openings in the seal <NUM> may correspond to the size and shape of the reservoir outlets in the insert <NUM>. In contrast, when in an unpunctured state, the seal <NUM> will have a planar form and only one opening (e.g., central opening). The seal <NUM> is designed to be strong enough to remain intact during the normal movement and/or handling of the non-nicotine pod assembly <NUM> so as to avoid being prematurely/inadvertently breached. For instance, the seal <NUM> may be a coated foil (e.g., aluminum-backed polyethylene terephthalate (PET)).

<FIG> is a partially exploded view involving the second housing section of the non-nicotine pod assembly of <FIG>. Referring to <FIG>, the second housing section <NUM> is structured to contain various components configured to release, receive, and heat the non-nicotine pre-vapor formulation. For instance, the first activation pin 314a and the second activation pin 314b are configured to puncture the reservoir in the first housing section <NUM> to release the non-nicotine pre-vapor formulation. Each of the first activation pin 314a and the second activation pin 314b has a distal end that extends through corresponding openings in the second housing section <NUM>. In an example embodiment, the distal ends of the first activation pin 314a and the second activation pin 314b are visible after assembly (e.g., <FIG>), while the remainder of the first activation pin 314a and the second activation pin 314b are hidden from view within the non-nicotine pod assembly <NUM>. In addition, each of the first activation pin 314a and the second activation pin 314b has a proximal end that is positioned so as to be adjacent to and upstream from the seal <NUM> prior to activation of the non-nicotine pod assembly <NUM>. When the first activation pin 314a and the second activation pin 314b are pushed into the second housing section <NUM> to activate the non-nicotine pod assembly <NUM>, the proximal end of each of the first activation pin 314a and the second activation pin 314b will advance through the insert <NUM> and, as a result, puncture the seal <NUM>, which will release the non-nicotine pre-vapor formulation from the reservoir. The movement of the first activation pin 314a may be independent of the movement of the second activation pin 314b (and vice versa). The first activation pin 314a and the second activation pin 314b will be discussed in more detail herein.

The absorbent material <NUM> is configured to engage with the holder portion of the insert <NUM> (which, as shown in <FIG>, projects from the upstream side of the insert <NUM>). The absorbent material <NUM> may have an annular form, although example embodiments are not limited thereto. As depicted in <FIG>, the absorbent material <NUM> may resemble a hollow cylinder. In such an instance, the outer diameter of the absorbent material <NUM> may be substantially equal to (or slightly larger than) the length of the wick <NUM>. The inner diameter of the absorbent material <NUM> may be smaller than the average outer diameter of the holder portion of the insert <NUM> so as to result in an interference fit. To facilitate the engagement with the absorbent material <NUM>, the tip of the holder portion of the insert <NUM> may be tapered. In addition, although hidden from view in <FIG>, the downstream side of the second housing section <NUM> may define a concavity configured receive and support the absorbent material <NUM>. An example of such a concavity may be a circular chamber that is in fluidic communication with and downstream from the cavity <NUM>. The absorbent material <NUM> is configured to receive and hold a quantity of the non-nicotine pre-vapor formulation released from the reservoir when the non-nicotine pod assembly <NUM> is activated.

The wick <NUM> is positioned within the non-nicotine pod assembly <NUM> so as to be in fluidic communication with the absorbent material <NUM> such that the non-nicotine pre-vapor formulation can be drawn from the absorbent material <NUM> to the heater <NUM> via capillary action. The wick <NUM> may physically contact an upstream side of the absorbent material <NUM> (e.g., bottom of the absorbent material <NUM> based on the view shown in <FIG>). In addition, the wick <NUM> may be aligned with a diameter of the absorbent material <NUM>, although example embodiments are not limited thereto.

As illustrated in <FIG> (as well as previous <FIG>), the heater <NUM> may have a folded configuration so as to grip and establish thermal contact with the opposing surfaces of the wick <NUM>. The heater <NUM> is configured to heat the wick <NUM> during vaping to generate a non-nicotine vapor. To facilitate such heating, the first end of the heater <NUM> may be electrically connected to the first power contact 324a via the first electrical lead 340a, while the second end of the heater <NUM> may be electrically connected to the second power contact 324b via the second electrical lead 340b. As a result, an electric current may be supplied from a power source (e.g., battery) within the device body <NUM> and conveyed to the heater <NUM> via the first power contact 324a and the first electrical lead 340a (or via the second power contact 324b and the second electrical lead 340b). The first electrical lead 340a and the second electrical lead 340b (which are shown separately in <FIG>) may be engaged with the contact core <NUM> (as shown in <FIG>). The relevant details of other aspects of the connector module <NUM>, which is configured to be seated within the cavity <NUM> of the second housing section <NUM>, that have been discussed supra (e.g., in connection with <FIG>) and will not be repeated in this section in the interest of brevity. During vaping, the non-nicotine vapor generated by the heater <NUM> is drawn through the vapor conduit of the insert <NUM>, through the vapor channel <NUM> of the first housing section <NUM>, out the pod outlet <NUM> of the non-nicotine pod assembly <NUM>, and through the vapor passage <NUM> of the mouthpiece <NUM> to the vapor outlet(s).

<FIG> is an exploded view of the activation pin in <FIG>. Referring to <FIG>, the activation pin may be in the form of a first activation pin 314a and a second activation pin 314b. While two activation pins are shown and discussed in connection with the non-limiting embodiments herein, it should be understood that, alternatively, the non-nicotine pod assembly <NUM> may include only one activation pin. In <FIG>, the first activation pin 314a may include a first blade 348a, a first actuator 350a, and a first O-ring 352a. Similarly, the second activation pin 314b may include a second blade 348b, a second actuator 350b, and a second O-ring 352b.

In an example embodiment, the first blade 348a and the second blade 348b are configured to be mounted or attached to upper portions (e.g., proximal portions) of the first actuator 350a and the second actuator 350b, respectively. The mounting or attachment may be achieved via a snap-fit connection, an interference fit (e.g., friction fit) connection, an adhesive, or other suitable coupling technique. The top of each of the first blade 348a and the second blade 348b may have one or more curved or concave edges that taper upward to a pointed tip. For instance, each of the first blade 348a and the second blade 348b may have two pointed tips with a concave edge therebetween and a curved edge adjacent to each pointed tip. The radii of curvature of the concave edge and the curved edges may be the same, while their arc lengths may differ. The first blade 348a and the second blade 348b may be formed of a sheet metal (e.g., stainless steel) that is cut or otherwise shaped to have the desired profile and bent to its final form. In another instance, the first blade 348a and the second blade 348b may be formed of plastic.

Based on a plan view, the size and shape of the first blade 348a, the second blade 348b, and portions of the first actuator 350a and the second actuator 350b on which they are mounted may correspond to the size and shape of the reservoir outlets in the insert <NUM>. Additionally, as shown in <FIG>, the first actuator 350a and the second actuator 350b may include projecting edges (e.g., curved inner lips which face each other) configured to push the two punctured sections of the seal <NUM> into the reservoir as the first blade 348a and the second blade 348b advance into the reservoir. In a non-limiting embodiment, when the first activation pin 314a and the second activation pin 314b are fully inserted into the non-nicotine pod assembly <NUM>, the two flaps (from the two punctured sections of the seal <NUM>, as shown in <FIG>) may be between the curved sidewalls of the reservoir outlets of the insert <NUM> and the corresponding curvatures of the projecting edges of the first actuator 350a and the second actuator 350b. As a result, the likelihood of the two punctured openings in the seal <NUM> becoming obstructed (by the two flaps from the two punctured sections) may be reduced or prevented. Furthermore, the first actuator 350a and the second actuator 350b may be configured to guide the non-nicotine pre-vapor formulation from the reservoir toward the absorbent material <NUM>.

The lower portion (e.g., distal portion) of each of the first actuator 350a and the second actuator 350b is configured to extend through a bottom section (e.g., upstream end) of the second housing section <NUM>. This rod-like portion of each of the first actuator 350a and the second actuator 350b may also be referred to as the shaft. The first O-ring 352a and the second O-ring 352b may be seated in annular grooves in the respective shafts of the first actuator 350a and the second actuator 350b. The first O-ring 352a and the second O-ring 352b are configured to engage with the shafts of the first actuator 350a and the second actuator 350b as well as the inner surfaces of the corresponding openings in the second housing section <NUM> in order to provide a fluid-tight seal. As a result, when the first activation pin 314a and the second activation pin 314b are pushed inward to activate the non-nicotine pod assembly <NUM>, the first O-ring 352a and the second O-ring 352b may move together with the respective shafts of the first actuator 350a and the second actuator 350b within the corresponding openings in the second housing section <NUM> while maintaining their respective seals, thereby helping to reduce or prevent leakage of the non-nicotine pre-vapor formulation through the openings in the second housing section <NUM> for the first activation pin 314a and the second activation pin 314b. The first O-ring 352a and the second O-ring 352b may be formed of silicone.

<FIG> is a perspective view of the connector module of <FIG> without the wick, heater, electrical leads, and contact core. <FIG> is an exploded view of the connector module of <FIG>. Referring to <FIG>, the module housing <NUM> and the face plate <NUM> generally form the exterior framework of the connector module <NUM>. The module housing <NUM> defines the first module inlet <NUM> and a grooved edge <NUM>. The grooved edge <NUM> of the module housing <NUM> exposes the second module inlet <NUM> (which is defined by the bypass structure <NUM>). However, it should be understood that the grooved edge <NUM> may also be regarded as defining a module inlet (e.g., in combination with the face plate <NUM>). The face plate <NUM> has a grooved edge <NUM> which, together with the corresponding side surface of the cavity <NUM> of the second housing section <NUM>, defines the pod inlet <NUM>. In addition, the face plate <NUM> defines a first contact opening, a second contact opening, and a third contact opening. The first contact opening and the second contact opening may be square-shaped and configured to expose the first power contact 324a and the second power contact 324b, respectively, while the third contact opening may be rectangular-shaped and configured to expose the plurality of data contacts <NUM>, although example embodiments are not limited thereto.

The first power contact 324a, the second power contact 324b, a printed circuit board (PCB) <NUM>, and the bypass structure <NUM> are disposed within the exterior framework formed by the module housing <NUM> and the face plate <NUM>. The printed circuit board (PCB) <NUM> includes the plurality of data contacts <NUM> on its upstream side (which is hidden from view in <FIG>) and a sensor <NUM> on its downstream side. The bypass structure <NUM> defines the second module inlet <NUM> and a bypass outlet <NUM>.

During assembly, the first power contact 324a and the second power contact 324b are positioned so as to be visible through the first contact opening and the second contact opening, respectively, of the face plate <NUM>. Additionally, the printed circuit board (PCB) <NUM> is positioned such that the plurality of data contacts <NUM> on its upstream side are visible through the third contact opening of the face plate <NUM>. The printed circuit board (PCB) <NUM> may also overlap the rear surfaces of the first power contact 324a and the second power contact 324b. The bypass structure <NUM> is positioned on the printed circuit board (PCB) <NUM> such that the sensor <NUM> is within an air flow path defined by the second module inlet <NUM> and the bypass outlet <NUM>. When assembled, the bypass structure <NUM> and the printed circuit board (PCB) <NUM> may be regarded as being surrounded on at least four sides by the meandering structures of the first power contact 324a and the second power contact 324b. In an example embodiment, the bifurcated ends of the first power contact 324a and the second power contact 324b are configured to electrically connect to the first electrical lead 340a and the second electrical lead 340b.

When incoming air is received by the pod inlet <NUM> during vaping, the first module inlet <NUM> may receive a primary flow (e.g., larger flow) of the incoming air, while the second module inlet <NUM> may receive a secondary flow (e.g., smaller flow) of the incoming air. The secondary flow of the incoming air may improve the sensitivity of the sensor <NUM>. After exiting the bypass structure <NUM> through the bypass outlet <NUM>, the secondary flow rejoins with the primary flow to form a combined flow that is drawn into and through the contact core <NUM> so as to encounter the heater <NUM> and the wick <NUM>. In a non-limiting embodiment, the primary flow may be <NUM> - <NUM>% (e.g., <NUM> - <NUM>%) of the incoming air, while the secondary flow may be <NUM> - <NUM>% (e.g., <NUM> - <NUM>%) of the incoming air. However, it should be understood that other ranges may be utilized, which may be above or below the ranges disclosed above.

The first module inlet <NUM> may be a resistance-to-draw (RTD) port, while the second module inlet <NUM> may be a bypass port. In such a configuration, the resistance-to-draw for the non-nicotine e-vaping device <NUM> may be adjusted by changing the size of the first module inlet <NUM> (rather than changing the size of the pod inlet <NUM>). In an example embodiment, the size of the first module inlet <NUM> may be selected such that the resistance-to-draw is between <NUM> - <NUM> mmHaO (e.g., between <NUM> - <NUM> mmH<NUM>O). For instance, a diameter of <NUM> for the first module inlet <NUM> may result in a resistance-to-draw of <NUM> mmHaO. In another instance, a diameter of <NUM> for the first module inlet <NUM> may result in a resistance-to-draw of <NUM> mmH<NUM>O. In another instance, a diameter of <NUM> for the first module inlet <NUM> may result in a resistance-to-draw of <NUM> mmHaO. In yet another instance, a diameter of <NUM> for the first module inlet <NUM> may result in a resistance-to-draw of about <NUM> - <NUM> mmH<NUM>O. Notably, the size of the first module inlet <NUM>, because of its internal arrangement, may be adjusted without affecting the external aesthetics of the non-nicotine pod assembly <NUM>, thereby allowing for a more standardized product design for non-nicotine pod assemblies with various resistance-to-draw (RTD) while also reducing the likelihood of an inadvertent blockage of the incoming air. The non-nicotine pod assembly <NUM> as well as other aspects of the non-nicotine e-vaping device <NUM> may also be as described in <CIT>, titled "Non-nicotine Pod Assemblies And Non-nicotine E-vaping Devices" (Atty. No. 24000NV-<NUM>-US), filed concurrently herewith, and in <CIT>, titled "Non-nicotine Pod Assemblies And Non-nicotine E-vaping Devices" (Atty. No. 24000NV-<NUM>-US), filed concurrently herewith, the entire contents of each of which are incorporated herein by reference.

In an example embodiment, the non-nicotine pre-vapor formulation neither includes tobacco nor is derived from tobacco. A non-nicotine compound of the non-nicotine pre-vapor formulation may be part of, or included in a liquid or a partial-liquid that includes an extract, an oil, an alcohol, a tincture, a suspension, a dispersion, a colloid, a general non-neutral (slightly acidic or slightly basic) solution, or combinations thereof. During the preparation of the non-nicotine pre-vapor formulation, the non-nicotine compound may be infused into, comingled, or otherwise combined with the other ingredients of the non-nicotine pre-vapor formulation.

In an example embodiment, the non-nicotine compound undergoes a slow, natural decarboxylation process over an extended duration of time at relatively low temperatures, including at or below room temperature (e.g., <NUM> °F). In addition, the non-nicotine compound may undergo a significantly elevated decarboxylation process (e.g., <NUM>% decarboxylation or greater) if exposed to elevated temperatures, especially in the range of about <NUM> °F or greater over a period of time (minutes or hours) at a relatively low pressure such as <NUM> atmosphere. Higher temperatures of about <NUM> °F or greater can cause a rapid or instantaneous decarboxylation to occur at a relatively high decarboxylation rate, although further elevated temperatures can cause a degradation of some or all of the chemical properties of the non-nicotine compound(s).

In an example embodiment, the non-nicotine compound may be from a medicinal plant (e.g., a naturally-occurring constituent of a plant that provides a medically-accepted therapeutic effect). The medicinal plant may be a cannabis plant, and the constituent may be at least one cannabis-derived constituent. Cannabinoids (e.g., phytocannabinoids) and terpenes are examples of cannabis-derived constituents. 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. Cannabis-derived materials may include the leaf and/or flower material from one or more species of cannabis plants, or extracts from the one or more species of cannabis plants. For instance, the one or more species of cannabis plants may include Cannabis sativa, Cannabis indica, and Cannabis ruderalis. In some example embodiments, the non-nicotine pre-vapor formulation includes a mixture of cannabis and/or cannabis-derived constituents that are, or are derived from, <NUM>-<NUM>% (e.g., <NUM>%) Cannabis sativa and <NUM>-<NUM>% (e.g., <NUM>%) Cannabis indica.

Non-limiting examples of cannabis-derived 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), while cannabidiolic acid (CBDA) is precursor of cannabidiol. 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 the heater may cause decarboxylation to convert tetrahydrocannabinolic acid (THCA) in the non-nicotine pre-vapor formulation to tetrahydrocannabinol (THC), and/or to convert cannabidiolic acid (CBDA) in the non-nicotine pre-vapor formulation to cannabidiol (CBD).

In instances where both tetrahydrocannabinolic acid (THCA) and tetrahydrocannabinol (THC) are present in the non-nicotine pre-vapor formulation, the decarboxylation and resulting conversion will cause a decrease in tetrahydrocannabinolic acid (THCA) and an increase in tetrahydrocannabinol (THC). At least <NUM>% (e.g., at least <NUM>%) of the tetrahydrocannabinolic acid (THCA) may be converted to tetrahydrocannabinol (THC), via the decarboxylation process, during the heating of the non-nicotine pre-vapor formulation for purposes of vaporization. Similarly, in instances where both cannabidiolic acid (CBDA) and cannabidiol (CBD) are present in the non-nicotine pre-vapor formulation, the decarboxylation and resulting conversion will cause a decrease in cannabidiolic acid (CBDA) and an increase in cannabidiol (CBD). At least <NUM>% (e.g., at least <NUM>%) of the cannabidiolic acid (CBDA) may be converted to cannabidiol (CBD), via the decarboxylation process, during the heating of the non-nicotine pre-vapor formulation for purposes of vaporization.

The non-nicotine pre-vapor formulation may contain the non-nicotine compound that provides the medically-accepted therapeutic effect (e.g., treatment of pain, nausea, epilepsy, psychiatric disorders). Details on methods of treatment may be found in <CIT>, titled "VAPORIZING DEVICES AND METHODS FOR DELIVERING A COMPOUND USING THE SAME," the disclosure of which is incorporated herein in its entirety by reference.

In an example embodiment, at least one flavorant is present in an amount ranging from about <NUM>% to about <NUM>% by weight (e.g., about <NUM>% to <NUM>%, about <NUM>% to <NUM>%, or about <NUM>% to <NUM>%) based on a total weight of the non-nicotine pre-vapor formulation. The 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. The at least one flavorant may include volatile cannabis flavor compounds (flavonoids) or other flavor compounds instead of, or in addition to, the cannabis flavor compounds. For instance, the at least one flavorant may include menthol, wintergreen, peppermint, cinnamon, clove, combinations thereof, and/or extracts thereof. In addition, flavorants may be included to provide other herb flavors, fruit flavors, nut flavors, liquor flavors, roasted flavors, minty flavors, savory flavors, combinations thereof, and any other desired flavors.
