Referring to <FIG>, an e-vaping device <NUM> includes a replaceable cartridge (or first section) <NUM> and a reusable power supply section (or second section) <NUM>. The sections <NUM>, <NUM> may be coupled together at complimentary interfaces <NUM>, <NUM> of the respective sections <NUM>, <NUM>.

In some example embodiments, the interfaces <NUM>, <NUM> are threaded connectors. It should be appreciated that an interface <NUM>, <NUM> may be any type of connector, including, without limitation, at least one of a snug-fit, detent, clamp, bayonet, or clasp.

As shown in <FIG>, in some example embodiments, an outlet end insert <NUM> may be positioned at an outlet end of the cartridge <NUM>. The outlet end insert <NUM> includes at least one outlet port <NUM> that may be located off-axis from the longitudinal axis of the e-vaping device <NUM>. One or more of the outlet ports <NUM> may be angled outwardly in relation to the longitudinal axis of the e-vaping device <NUM>. Multiple outlet ports <NUM> may be uniformly or substantially uniformly distributed about the perimeter of the outlet end insert <NUM> so as to substantially uniformly distribute vapor drawn through the outlet end insert <NUM> during vaping. Therefore, as a vapor is drawn through the outlet end insert <NUM>, the vapor may move in different directions.

The cartridge <NUM> includes a vaporizer assembly <NUM> and an additive assembly <NUM>. The vaporizer assembly <NUM> may form a generated vapor <NUM>, and the additive assembly <NUM> may form a flavored vapor <NUM> based on releasing one or more additives into the generated vapor <NUM> formed by the vaporizer assembly <NUM>.

In some example embodiments, the additive assembly <NUM> is configured to release one or more additives into the generated vapor <NUM> based on desorbing one or more additives from one or more adsorbent materials included in the additive assembly <NUM>.

In some example embodiments, the additive assembly <NUM> is configured to release one or more additives into the generated vapor <NUM> based on desorption of the one or more additives from the one or more adsorbent materials. The one or more additives may be desorbed from the one or more additive materials based on one or more elements of the generated vapor <NUM> adsorbing on the one or more adsorbent materials, thereby displacing the one or more additives on the one or more adsorbent materials. In some example embodiments, the additive assembly <NUM> reacts with one or more elements of the generated vapor <NUM> to release the one or more additives.

As described further below, the one or more elements of the generated vapor <NUM> may include one or more elements of a pre-vapor formulation from which the generated vapor <NUM> is formed.

In some example embodiments, the outer housing <NUM> may be a single tube housing both the cartridge <NUM> and the power supply section <NUM> and the entire e-vaping device <NUM> may be disposable. The outer housing <NUM> may have a generally cylindrical cross-section. In some example embodiments, the outer housing <NUM> may have a generally triangular cross-section along one or more of the cartridge <NUM> and the power supply section <NUM>.

The connector element <NUM> may be included in the interface <NUM>.

In some example embodiments, a nose portion of gasket <NUM> is fitted into another end portion of the inner tube <NUM>. An outer perimeter of the gasket <NUM> may provide a substantially airtight seal with an interior surface of the outer housing <NUM>. The gasket <NUM> includes a passage <NUM> disposed between the channel <NUM> of the inner tube <NUM> and the interior of an outlet end insert <NUM>. The passage <NUM> may transport a vapor from the channel <NUM> to the outlet end insert <NUM> via the additive assembly <NUM>.

In some example embodiments, at least one air inlet port <NUM> may be formed in the outer housing <NUM>, adjacent to the interface <NUM> to minimize the probability of an adult vaper's fingers occluding one of the ports and to control the resistance-to-draw (RTD) during vaping. In some example embodiments, the air inlet ports <NUM> may be machined into the outer housing <NUM> with precision tooling such that their diameters are closely controlled and replicated from one e-vaping device <NUM> to the next during manufacture.

In some example embodiments, the air inlet ports <NUM> may be drilled with carbide drill bits or other high-precision tools or techniques. In some example embodiments, the outer housing <NUM> may be formed of metal or metal alloys such that the size and shape of the air inlet ports <NUM> may not be altered during manufacturing operations, packaging, and vaping. Therefore, the air inlet ports <NUM> may provide consistent RTD. In some example embodiments, the air inlet ports <NUM> may be sized and configured such that the e-vaping device <NUM> has a RTD in the range of from about <NUM> millimetres of water to about <NUM> millimetres of water.

Still referring to <FIG>, the reservoir <NUM> may include a pre-vapor formulation. The space defined between the gaskets <NUM> and <NUM>, the outer housing <NUM> and the inner tube <NUM> may establish the confines of the reservoir <NUM>, such that the reservoir <NUM> may be contained in an outer annulus between the inner tube <NUM>, the outer housing <NUM> and the gaskets <NUM> and <NUM>. Therefore, the reservoir <NUM> may at least partially surround the channel <NUM>.

The dispensing interface <NUM> is coupled to the reservoir <NUM>, such that the dispensing interface <NUM> may extend transversely across the channel <NUM> between opposing portions of the reservoir <NUM>. The dispensing interface <NUM> is configured to draw pre-vapor formulation from the reservoir <NUM>.

In some example embodiments, the heating element <NUM> may extend parallel to a longitudinal axis of the channel <NUM>.

The dispensing interface <NUM> is configured to draw pre-vapor formulation from the reservoir <NUM>, such that the pre-vapor formulation may be vaporized from the dispensing interface <NUM> based on heating of the dispensing interface <NUM> by the heating element <NUM>.

During vaping, pre-vapor formulation may be transferred from at least one of the reservoir <NUM> or storage medium in the proximity of the heating element <NUM> via capillary action of a dispensing interface <NUM>. The dispensing interface <NUM> may include a first end portion and a second end portion. The first and second end portions of the dispensing interface <NUM> may extend into opposite sides of the reservoir <NUM>. Dispensing interface <NUM> end portions may be referred to herein as roots. The heating element <NUM> may at least partially surround a central portion of the dispensing interface <NUM> such that when the heating element <NUM> is activated to generate heat, the pre-vapor formulation in the central portion of the dispensing interface <NUM> may be vaporized by the heating element <NUM> to form a vapor. The central portion of a dispensing interface <NUM> may be referred to herein as a trunk.

The reservoir <NUM> may include a pre-vapor formulation which is free of flavorants, such that when the vaporizer assembly <NUM> forms a vapor <NUM>, via vaporization of a pre-vapor formulation by the heating element <NUM>, the vapor <NUM> may be substantially absent of flavor, thereby being a "generated vapor. " Such an absence of flavorants in the reservoir <NUM> of the vaporizer assembly <NUM> may result in mitigation of chemical reactions between pre-vapor formulation materials and the flavorants in the reservoir <NUM> and upon vaporization as a result of heating of the pre-vapor formulation by the heating element <NUM>.

Still referring to <FIG>, the additive assembly <NUM> is positioned between the vaporizer assembly <NUM> and the outlet end insert <NUM>. As shown in <FIG>, the additive assembly <NUM> may be spaced apart from the vaporizer assembly <NUM> such that at least the additive assembly <NUM>, vaporizer assembly <NUM>, and outer housing <NUM> define a space <NUM> between the additive assembly <NUM> and the vaporizer assembly <NUM>. A generated vapor <NUM> formed by the vaporizer assembly <NUM> may pass through space <NUM> such that the generated vapor <NUM> is in fluid communication with the additive assembly <NUM>. In some example embodiments, the additive assembly <NUM> is located within the space <NUM> such that a generated vapor <NUM> may pass around at least one outer surface of the additive assembly <NUM> through the space <NUM>.

The additive assembly <NUM> is configured to form a flavored vapor <NUM> based on releasing one or more additives into a generated vapor <NUM> passing in fluid communication with one or more portions of the additive assembly <NUM>.

The additive assembly <NUM> is positioned in fluid communication with both the vaporizer assembly <NUM> and the outlet end insert <NUM>. The cartridge <NUM> may be configured to direct generated vapor <NUM> formed by the vaporizer assembly <NUM> to exit the cartridge <NUM> via the outlet ports <NUM>. The cartridge <NUM> may further be configured to direct the generated vapor <NUM> to pass in fluid communication with the additive assembly <NUM> towards the outlet ports <NUM>. Passing in fluid communication with the additive assembly <NUM> may include passing through at least a portion of the additive assembly <NUM>.

The additive assembly <NUM> may hold an additive and may be configured to release the additive into a generated vapor <NUM> formed by the vaporizer assembly <NUM> to form a flavored vapor <NUM>. As described further below, in some example embodiments the additive is carbon dioxide, and the additive assembly <NUM> may include one or more adsorbent materials onto which carbon dioxide is adsorbed. The additive assembly <NUM> may be configured to release an additive that is carbon dioxide into the generated vapor <NUM> to form a flavored vapor <NUM>. The additive assembly <NUM> may release the carbon dioxide into the generated vapor <NUM> based on one or more elements of the generated vapor <NUM> adsorbing onto the adsorbent material.

The additive assembly <NUM>, as discussed further below, may include a porous structure. The porous structure may hold an additive in fluid communication with at least one of the vaporizer assembly <NUM> and the space <NUM>, so that generated vapor <NUM> may pass at least partially through the porous structure and in fluid communication with the additive held in the porous structure. The generated vapor <NUM> may act as an eluent, eluting the additive from the porous structure and into the generated vapor <NUM> to form an eluate. The eluate may include the generated vapor <NUM> and the additive. Such an eluate may be referred to as the flavored vapor <NUM>.

In some example embodiments, an additive eluted into the generated vapor <NUM> is in a particulate phase. A particulate phase may include a liquid phase, solid phase, or the like. In some example embodiments, an additive eluted into the generated vapor <NUM> is in a vapor phase, gas phase, and so forth. An additive may include a volatile flavor substance, and the volatile flavor substance may be eluted into the generated vapor <NUM>. In some example embodiments, an additive eluted into the generated vapor <NUM> includes a nonvolatile flavor substance.

In some example embodiments, when the additive assembly <NUM> holds the additive separate from the vaporizer assembly <NUM> and the cartridge <NUM> is configured to direct generated vapor <NUM> through the additive assembly <NUM> subsequent to formation of the generated vapor <NUM>, the generated vapor <NUM> may be cooled from an initial temperature at formation in the vaporizer assembly <NUM>. Where the generated vapor <NUM> passing through the additive assembly <NUM> is cooled from the initial temperature, chemical reactions between the additive eluted into the generated vapor <NUM> and the elements of the generated vapor <NUM> may be at least partially mitigated.

In some example embodiments, when the e-vaping device <NUM> includes an additive assembly <NUM> that holds an additive separate from the vaporizer assembly <NUM>, the e-vaping device <NUM> may be configured to mitigate a probability of chemical reactions between the additive and one or more elements of the vaporizer assembly <NUM>. An absence of such chemical reactions may result in an absence of reaction products in the flavored vapor <NUM>. Such reaction products may detract from a sensory experience provided by the flavored vapor <NUM>. As a result, an e-vaping device <NUM> that is configured to mitigate the probability of such chemical reactions may provide a more consistent and improved sensory experience through the flavored vapor <NUM>.

In some example embodiments, the additive included in an e-vaping device <NUM> may be replaceable independently of the pre-vapor formulation in the cartridge <NUM>, as the flavorants are included in an additive assembly <NUM> that is separate from the vaporizer assembly <NUM> in which the pre-vapor formulation is included. The additive assembly <NUM> may be replaced with another additive assembly <NUM> to swap the additive included in the e-vaping device <NUM> as desired by an adult vaper. The additive assembly <NUM> may be replaced with another additive assembly <NUM> to replenish additives in the e-vaping device <NUM> without replacing a vaporizer assembly <NUM>, where the vaporizer assembly <NUM> may include sufficient pre-vapor formulation to support additional vaping.

The heater activation light <NUM> may include a light emitting diode (LED). Moreover, the heater activation light <NUM> may be arranged to be visible to an adult vaper during vaping. In addition, the heater activation light <NUM> may be utilized for e-vaping system diagnostics or to indicate that recharging is in progress.

The carbon dioxide <NUM> may be desorbed from an adsorbent material bead <NUM> based on one or more elements of the generated vapor <NUM> adsorbing on the adsorbent material of a bead <NUM> such that the carbon dioxide <NUM> is displaced from the adsorbent material.

In the example embodiments illustrated in <FIG>, the carbon dioxide <NUM> is illustrated as being adsorbed on to the surfaces on an exterior of the adsorbent material beads <NUM>. It will be understood that, in some example embodiments, the carbon dioxide <NUM> may be at least partially distributed throughout an interior of one or more adsorbent materials, including one or more adsorbent material beads <NUM>. The carbon dioxide <NUM> may be adsorbed to internal surfaces, including one or more internal pore surfaces, in an interior of the adsorbent material and distributed into the interior of the adsorbent material. In some example embodiments, carbon dioxide <NUM> is both adsorbed on to one or more external surfaces of an adsorbent material, including one or more external pore surfaces, and adsorbed on to one or more internal surfaces, including one or more internal pore surfaces. The carbon dioxide <NUM> may therefore be distributed throughout at least a portion of an interior of the adsorbent material in addition to being on an external surface of the adsorbent material.

In some example embodiments, the additive assembly <NUM> at least partially encloses the one or more adsorbent material structures in a containment structure. The containment structure may be configured to hold the one or more adsorbent material structures in a fixed volume.

The mesh structure may be partially permeable, such that the mesh structure is configured to direct vapor <NUM>, <NUM> across the mesh and restrict at least the adsorbent material beads <NUM> from passing through one or more of the openings <NUM>, <NUM>.

In some example embodiments, the additive assembly <NUM> includes one or more flavor materials that hold one or more flavorants. The one or more flavor materials may release the one or more flavorants into the generated vapor <NUM> when the generated vapor <NUM> passes in fluid communication with the flavor materials.

An additive assembly <NUM> that includes an adsorbent material and a flavor material may be configured to release both carbon dioxide and one or more flavorants into the generated vapor <NUM> to form a flavored vapor <NUM>. In the example embodiments illustrated in <FIG>, for example, the additive assemblies <NUM> include flavor materials <NUM>, <NUM> in addition to the adsorbent material beads <NUM>.

As shown in <FIG>, a flavor material may have one or more various shapes. For example, in the example embodiment illustrated in <FIG>, the flavor material <NUM> is a "shredded" material having a fibrous shape. The flavor material <NUM> extends between adsorbent material beads <NUM> throughout the interior of the additive assembly <NUM>. In another example, in the example embodiment illustrated in <FIG>, the flavor material <NUM> is a bead-shaped material that is packed with the adsorbent material beads <NUM> into the additive assembly <NUM>.

In the illustrated example embodiments of <FIG>, the additive assemblies <NUM> each include a uniform or substantially uniform mixture of adsorbent material beads <NUM> and at least one of the flavor materials <NUM>, <NUM>. For example, in the illustrated example embodiment of <FIG>, the adsorbent material beads <NUM> and flavor material beads <NUM> are substantially uniformly mixed.

In some example embodiments, the mixture of adsorbent materials and flavor materials in the additive assembly <NUM> may be a non-uniform mixture. For example, a concentration of flavor materials in the additive assembly <NUM> may be greater with increased proximity to the opening <NUM>, relative to the opening <NUM>. As a result, a generated vapor <NUM> passing in fluid communication with the flavor materials may include carbon dioxide released from adsorbent material beads <NUM> that are closer to the opening <NUM> than the opening <NUM>.

In some example embodiments, an adsorbent material included in the additive assembly <NUM> may be configured to generate heat based on one or more elements of generated vapor <NUM> adsorbing on the adsorbent material, such that the adsorbent material is configured to release both carbon dioxide and heat when one or more elements of the generated vapor <NUM> adsorb onto the adsorbent material. For example, an adsorbent material bead <NUM> may release heat based on one or more elements of the generated vapor <NUM> adsorbing onto the adsorbent material bead <NUM> and displacing at least some carbon dioxide <NUM> from the adsorbent material bead <NUM>.

In some example embodiments, one or more flavor materials included in the additive assembly <NUM> are configured to absorb the heat generated by the adsorbent material included in the additive assembly <NUM>. A flavor material may release an increased amount of flavorant, via elution into a generated vapor <NUM>, based on an increased temperature of the flavor material. When the flavor material absorbs heat generated by adsorbent material in the additive assembly <NUM>, the flavor material may release an increased amount of flavorant into the generated vapor <NUM>, relative to an unheated flavor material.

In the example embodiments illustrated in <FIG>, the additive assembly <NUM> is configured to enable improved elution of flavorant into a generated vapor <NUM> based on elution of carbon dioxide <NUM> into the generated vapor <NUM>.

The generated heat may be absorbed by flavor materials <NUM>, <NUM> to heat the flavor materials <NUM>, <NUM>. Flavorants may be eluted from the flavor materials <NUM>, <NUM> into a generated vapor <NUM> passing in fluid communication with the additive assembly <NUM>. The flavorant elution into the generated vapor <NUM> may be improved, relative to an additive assembly <NUM> in which the adsorbent material beads <NUM> are absent, based on the adsorbent material-generated heat that is absorbed by the flavor materials <NUM>, <NUM>.

Referring to <FIG>, in some example embodiments, an additive assembly <NUM> may include one or more structures that include at least one of adsorbent material and flavor material. Such one or more structures may be porous structures that include at least one of adsorbed carbon dioxide and one or more flavorants. The one or more structures may be configured to release at least one of carbon dioxide and one or more flavorants into a generated vapor <NUM> when the generated vapor <NUM> flows in fluid communication with the one or more structures.

Referring to the example embodiment illustrated in <FIG>, the additive assembly <NUM> includes a structure <NUM> configured to release at least carbon dioxide into a generated vapor <NUM> flowing in fluid communication with the structure <NUM>.

The structure <NUM> may be configured to enable elution of one or more flavorants into a generated vapor <NUM> flowing through the internal structure of structure <NUM>.

In some example embodiments, the additive assembly <NUM> may include multiple structures <NUM>. Separate structures <NUM> may include different ones of an adsorbent material holding adsorbed carbon dioxide and a flavor material holding one or more flavorants. For example, an additive assembly <NUM> may include a first structure <NUM> that is proximate to the vaporizer assembly <NUM> and a second structure <NUM> that is distal from the vaporizer assembly <NUM>. The first structure <NUM> may include an adsorbent material on which carbon dioxide is adsorbed, and the second structure <NUM> may include a flavor material holding one or more flavorants. A generated vapor <NUM> formed by the vaporizer assembly <NUM> may first flow in fluid communication with the first structure <NUM> to elute carbon dioxide from the first structure <NUM> and carry heat generated by adsorbent material included in the first structure <NUM>. The generated vapor <NUM> may then flow in fluid communication with the second structure <NUM> and transfer the carried heat to the second structure <NUM>. The generated vapor <NUM> may elute one or more flavorants from the second structure <NUM>, where flavorant elution is based at least in part upon the heat transferred to the second structure <NUM>.

In some example embodiments, the structure <NUM> may be configured to release one or more of carbon dioxide and one or more flavorants into a generated vapor <NUM> flowing in fluid communication with an outer surface of the structure <NUM>. For example, the structure <NUM> may be configured to direct the generated vapor <NUM> to flow around one or more outer surfaces of the structure <NUM>. The structure <NUM> may include at least one of carbon dioxide adsorbed to an outer surface and one or more flavorants that may be eluted through an outer surface.

In some example embodiments, at least one of the passages <NUM> may include one or more adsorbent materials configured to adsorb carbon dioxide, and at least one of the passages <NUM> may include one or more flavor materials configured to hold one or more flavorants.

<FIG> is a schematic illustration of the adsorbent material and flavor material included in an additive assembly releasing carbon dioxide and flavorant into a generated vapor to form a flavored vapor. The example embodiment of the additive assembly <NUM> shown in <FIG> may be included in any of the embodiments included herein, including the additive assembly <NUM> shown in <FIG>.

In some example embodiments, an additive assembly <NUM> includes at least one adsorbent material <NUM> and at least one flavor material <NUM>. In the example embodiment illustrated in <FIG>, the adsorbent material <NUM> includes a plurality of adsorbent material beads <NUM>. In the example embodiment illustrated in <FIG>, the adsorbent material <NUM> includes carbon dioxide <NUM> adsorbed on one or more external and internal pore surfaces of the adsorbent material beads <NUM>. The flavor material <NUM> includes one or more flavor material beads <NUM> holding at least the flavorants <NUM>. In some example embodiments, the one or more flavorants <NUM> are held within external and internal pore surfaces of the flavor material beads <NUM>. A desorption pathway, adsorption pathway, displacement pathway, some combination thereof, or the like with regard to an adsorbent material may include a process that occurs at the molecular level at the adsorption sites of the adsorbent material.

The example embodiment illustrated in <FIG> further shows that the adsorbent material <NUM> is closer to a source of generated vapor (for example, at least one of vaporizer assembly <NUM> and space <NUM> illustrated in <FIG>) than the flavor material <NUM>. However, it will be understood that, in some example embodiments, the additive assembly <NUM> may include a uniform or substantially uniform mixture of adsorbent material <NUM> and flavor material <NUM>.

The additive assembly <NUM> may be configured to release carbon dioxide <NUM> into a generated vapor <NUM> that flows in fluid communication with the adsorbent material <NUM>, based at least in part upon one or more elements of the generated vapor <NUM> adsorbing on one or more structures of the adsorbent material <NUM> to desorb the carbon dioxide. The adsorbent material <NUM> may further generate and release heat <NUM> based on the one or more elements of the generated vapor <NUM> adsorbing on the one or more structures of the adsorbent material <NUM> to desorb the carbon dioxide. One or more elements or compounds within the vapor <NUM> may be adsorbed by the adsorbent, based on at least one of the relative binding energies of the one or more elements or compounds, the relative affinities of the one or more elements or compounds for one or more specific adsorbents, or both.

As shown in <FIG>, a generated vapor <NUM> may flow in fluid communication with the adsorbent material beads <NUM> such that one or more elements <NUM> of the generated vapor <NUM> adsorb <NUM> onto the adsorbent material beads <NUM> to desorb <NUM> at least some of the carbon dioxide <NUM> from the adsorbent material beads <NUM>. The carbon dioxide <NUM> may be desorbed based on displacement from the adsorbent material beads <NUM> by the one or more elements <NUM> of the generated vapor <NUM>. The one or more elements <NUM> of the generated vapor <NUM> may include at least one of water, beads, solvents, active ingredients, ethanol, plant extracts, natural or artificial flavors, and one or more pre-vapor formulations. A pre-vapor formulation may include at least one of glycerin and propylene glycol.

As shown in <FIG>, the desorbed <NUM> carbon dioxide <NUM> may be eluted into the generated vapor <NUM> to form a modified vapor <NUM>. The modified vapor <NUM> includes one or more elements <NUM> of the generated vapor <NUM> and at least some of the desorbed carbon dioxide <NUM>.

As shown in <FIG>, the adsorbent material <NUM> may, in addition to releasing carbon dioxide <NUM> through desorption <NUM>, generate heat <NUM> based on one or more elements <NUM> of the generated vapor <NUM> adsorbing onto the adsorbent material beads <NUM>. The heat <NUM> may be absorbed by one or more of the flavor material beads <NUM> included in the flavor material <NUM>. The heat may be transferred to the flavor material <NUM> through one or more of conduction, convection, and radiation. For example, when the flavor material beads <NUM> and adsorbent material beads <NUM> are in physical contact, the generated heat <NUM> may be transferred from the adsorbent material beads <NUM> to the flavor material beads <NUM> through conduction. In another example, the heat <NUM> may be transferred to at least some of the flavor material beads <NUM> by the modified vapor <NUM> through convection. In some example embodiments, heat generated in the system may facilitate (enable) the release of a greater amount of flavorant to modified vapor <NUM>. Some flavorant mays transfer to stream <NUM> through an elution/entrainment type of mechanism (for example, a concentration driven mechanism, concentration gradient, or both, between the flavorant carrier and the passing vapor). Such a transfer may occur even in the absence of heat generation at the adsorbent material beads <NUM> and absorption at flavor material <NUM>.

The flavor material <NUM> included in the additive assembly <NUM> may be configured to release one or more flavorants into a vapor flowing in fluid communication with the flavor material <NUM> based at least in part upon absorbing the heat <NUM> generated by the adsorbent material beads <NUM>. Based on the flavor material <NUM> and the adsorbent material beads <NUM>, the additive assembly <NUM> may be configured to form a flavored vapor <NUM> that includes both carbon dioxide and one or more flavorants.

As shown in <FIG>, the flavor material beads <NUM> may release the one or more flavorants <NUM> based at least in part upon absorbing at least some of the heat <NUM> generated by the adsorbent material beads <NUM>. At least one of the rate of flavorant <NUM> released by the flavor material <NUM> and the amount of flavorant <NUM> released by the flavor material <NUM> may vary in direct proportion to the amount of heat <NUM> absorbed by the flavor material <NUM>. As a result, the flavor material <NUM> may be configured to release more flavorant <NUM> into a vapor <NUM>, <NUM> passing in fluid communication with the flavor material <NUM> when the flavor material <NUM> absorbs heat <NUM> from the adsorbent material beads <NUM>, relative to the amount of flavorant <NUM> released by the flavor material <NUM> into a vapor <NUM>, <NUM> in the absence of absorbing such heat <NUM>. Therefore, flavorant <NUM> elution from the flavor material <NUM> may be augmented by the flavor material <NUM> absorbing the heat <NUM> generated by the adsorbent material beads <NUM>.

As shown in <FIG>, when the flavorants <NUM> are released from the flavor material <NUM> into a modified vapor <NUM>, the flavorants <NUM> may mix with the modified vapor <NUM> to form a flavored vapor <NUM>. The flavored vapor <NUM> may include one or more generated vapor elements <NUM>, carbon dioxide <NUM> released by the adsorbent material <NUM>, and flavorants <NUM> released by the flavor material <NUM>. The flavored vapor <NUM> may exit the additive assembly <NUM>.

The cartridge interface <NUM> may be configured to electrically couple the vaporizer assembly <NUM> with a power supply included in a separate power supply section of an e-vaping device.

The additive assembly module <NUM> may include an additive assembly <NUM> within the housing <NUM>. The additive assembly <NUM> shown in <FIG> may be the additive assembly <NUM> shown in any of <FIG>, <FIG>, <FIG>, <FIG>, <FIG>, and <FIG>.

As shown in <FIG>, the interface <NUM> of module <NUM> may include a conduit <NUM>. The conduit <NUM> may extend between the interface <NUM> and the interior of the housing <NUM>, such that the additive assembly <NUM> held within the housing <NUM> of the module <NUM> is held in fluid communication with an exterior of the module <NUM> through the conduit <NUM>.

The cartridge <NUM> may further include the additive assembly <NUM> being in fluid communication with the outlet ports <NUM>, such that generated vapor formed by the vaporizer assembly <NUM> may pass out of the cartridge <NUM> by following a pathway extending through the additive assembly <NUM> to the outlet ports <NUM>. The additive assembly compartment <NUM> within the housing <NUM> may direct generated vapor received into the additive assembly compartment <NUM> to pass through the additive assembly <NUM>.

As shown in <FIG>, the additive assembly module <NUM> may be configured to restrict fluid communication through the module <NUM> to be through the additive assembly <NUM>, such that generated vapor passing from the vaporizer assembly <NUM> to the outlet ports <NUM> in the formed cartridge <NUM> are restricted to passing through the additive assembly <NUM>.

As shown in <FIG>, a cartridge <NUM> may include additive assembly modules <NUM>-<NUM> to <NUM>-N and a vaporizer assembly module <NUM>. As also show, the cartridge <NUM> may, in some example embodiments, include an outlet end insert module <NUM>. Modules <NUM>, <NUM>-<NUM> to <NUM>-N, and <NUM> may be coupled together via complimentary interfaces <NUM>, <NUM>-<NUM> to <NUM>-N, <NUM>-<NUM> to <NUM>-N, and <NUM>. It will be understood that the interfaces may include any of the types of interfaces described herein. Each module <NUM>, <NUM>-<NUM> to <NUM>-N, and <NUM> may include a respective housing <NUM>, <NUM>-<NUM> to <NUM>-N, and <NUM>.

The additive assembly modules <NUM>-<NUM> to <NUM>-N may include separate additive assemblies <NUM>-<NUM> to <NUM>-N within the respective additive assembly compartments <NUM>-<NUM> to <NUM>-N thereof. The compartments <NUM>-<NUM> to <NUM>-N may be at least partially defined by the respective housings <NUM>-<NUM> to <NUM>-N. Each of the additive assemblies <NUM>-<NUM> to <NUM>-N shown in <FIG> may be the additive assembly <NUM> shown in any of <FIG>, <FIG>, <FIG>, <FIG>, <FIG>, and <FIG>.

As shown in <FIG>, the additive assembly modules <NUM>-<NUM> to <NUM>-N include respective pairs of interfaces <NUM>-<NUM>, <NUM>-<NUM> to <NUM>-N, <NUM>-N at opposite ends. The interfaces <NUM>-<NUM> to <NUM>-N may be configured to be interchangeably and removably coupled to any of the interfaces <NUM>-<NUM> to <NUM>-N.

One or more of interfaces <NUM>-<NUM> to <NUM>-N may be interchangeably and removably coupled to interface <NUM> of module <NUM>. As a result, the modules <NUM>-<NUM> to <NUM>-N may be interchangeably and removably coupled together in one or more various combinations and configurations.

Each of the additive assembly module interfaces <NUM>-<NUM> to <NUM>-N may include a respective conduit <NUM>-<NUM> to <NUM>-N, and each of the additive assembly module interfaces <NUM>-<NUM> to <NUM>-N may include a respective conduit <NUM>-<NUM> to <NUM>-N, such that each of the additive assemblies <NUM>-<NUM> to <NUM>-N held within the housing of each module <NUM>-<NUM> to <NUM>-N is held in fluid communication with an exterior of the respective module <NUM>-<NUM> to <NUM>-N through the conduits <NUM>-<NUM>, <NUM>-<NUM> to <NUM>-N, <NUM>-N of the respective module <NUM>-<NUM> to <NUM>-N.

As shown in <FIG>, when the modules <NUM>, <NUM>-<NUM> to <NUM>-N, and <NUM> are coupled together, the modules <NUM>, <NUM>-<NUM> to <NUM>-N, and <NUM> may form a cartridge <NUM>, where the cartridge includes an outlet end insert <NUM> at an outlet end and an interface <NUM> at a tip end.

<FIG> is a cross-sectional view of an additive assembly <NUM> that includes multiple additive structures according to some example embodiments. The additive assembly <NUM> shown in <FIG> may be included in any of the embodiments included herein, including the additive assembly <NUM> shown in <FIG>.

In some example embodiments, an additive assembly <NUM> includes multiple additive structures <NUM>-<NUM> to <NUM>-N. The additive assembly <NUM> may include a configuration of multiple additive structures <NUM>-<NUM> to <NUM>-N that collectively define one or more passages through the additive assembly <NUM>. The additive assembly <NUM> may be configured to direct a generated vapor <NUM> through one or more of the passages <NUM>-<NUM> to <NUM>-N to flow in fluid communication with one or more surfaces of the additive structures <NUM>-<NUM> to <NUM>-N.

As shown in <FIG>, additive assembly <NUM> includes additive structures <NUM>-<NUM> to <NUM>-N. The additive structures <NUM>-<NUM> to <NUM>-N may each include at least one of an adsorbent material and a flavor material. Different additive structures may include different materials. For example, additive structure <NUM>-<NUM> may include an adsorbent material on which carbon dioxide is adsorbed and additive structure <NUM>-N may include a flavor material holding at least one flavorant.

In some example embodiments, one or more of the additive structures <NUM>-<NUM> to <NUM>-N is a monolithic structure that restricts generated vapor <NUM> to flow along an outer surface of the respective one or more additive structures <NUM>-<NUM> to <NUM>-N.

As further shown in <FIG>, the additive structures <NUM>-<NUM> to <NUM>-N may be positioned in the additive assembly <NUM> in a configuration such that the additive structures <NUM>-<NUM> to <NUM>-N at least partially define one or more passages <NUM>-<NUM> to <NUM>-N through the additive assembly <NUM>. The additive assembly <NUM> shown in <FIG> may direct a generated vapor <NUM> entering the additive assembly <NUM> to flow through at least one of the passages <NUM>-<NUM> to <NUM>-N such that the generated vapor <NUM> flows in fluid communication with an outer surface of at least one of the additive structures <NUM>-<NUM> to <NUM>-N.

Based on directing at least a portion of the generated vapor <NUM> to flow through one or more passages in fluid communication with an outer surface of one or more additive structures <NUM>-<NUM> to <NUM>-N, the additive assembly <NUM> may enable improved release of at least one of flavorant and carbon dioxide into the generated vapor <NUM>. For example, based on including multiple additive structures <NUM>-<NUM> to <NUM>-N configured to define multiple passages <NUM>-<NUM> to <NUM>-N through the additive assembly <NUM>, the additive assembly <NUM> may include a greater additive structure outer surface area, relative to an additive assembly <NUM> that includes an individual additive structure <NUM>-<NUM>. Based on including such an increased outer surface area, the additive assembly <NUM> shown in <FIG> may be configured to provide improved release of one or more additives into a generated vapor <NUM> flowing in fluid communication with the one or more additive structures <NUM>-<NUM> to <NUM>-N.

<FIG> is a cross-sectional view of an additive assembly <NUM> that includes multiple additive structures <NUM>-<NUM> to <NUM>-<NUM> and <NUM> according to some example embodiments. The additive assembly <NUM> shown in <FIG> may be included in any of the embodiments included herein, including the additive assembly <NUM> shown in <FIG>.

In some example embodiments, an additive assembly <NUM> may include a configuration of multiple additive structures that collectively define one or more passages through the additive assembly <NUM>. The one or more passages may include portions having different orientations. A vapor flowing through the one or more passages may change direction based on flowing through differently-oriented passage portions. When a vapor flows from a first passage portion having a first orientation to another passage portion having a different orientation, the vapor may impinge on an outer surface of an additive structure. Additive release from the additive structure may be improved, based on the impingement.

As shown in <FIG>, additive assembly <NUM> includes a configuration of additive structures <NUM>-<NUM> to <NUM>-<NUM> and <NUM> that collectively define a passage <NUM> through the additive assembly <NUM>. The passage <NUM> includes portions having portions <NUM>-<NUM> and <NUM>-<NUM>.

Additive structures <NUM>-<NUM> to <NUM>-<NUM> define a first portion <NUM>-<NUM> of the passage <NUM> through the additive assembly <NUM>. The first portion <NUM>-<NUM> of the passage <NUM> is oriented to extend in parallel or substantially in parallel with a longitudinal axis of the additive assembly <NUM>.

Additive structures <NUM>-<NUM> to <NUM>-<NUM> and <NUM> at least partially define portions <NUM>-<NUM> of the passage <NUM>. Portions <NUM>-<NUM> are oriented to extend orthogonally or substantially orthogonally to the longitudinal axis of the additive assembly <NUM>. As shown, the passage <NUM> first portion <NUM>-<NUM> extends orthogonally or substantially orthogonally to an outer surface <NUM> of the additive structure <NUM>.

Based on the orientations of portions <NUM>-<NUM> and <NUM>-<NUM> of the passage <NUM>, a generated vapor <NUM> flowing through the passage <NUM> from portion <NUM>-<NUM> to one of the portions <NUM>-<NUM> may impinge upon the outer surface <NUM> of the additive structure <NUM>.

In some example embodiments, the additive structure <NUM> may divert at least a portion of the impinging generated vapor <NUM> to flow through portions <NUM>-<NUM> of the passage <NUM> such that the generated vapor <NUM> flows in fluid communication with one or more outer surfaces <NUM> of the additive structure <NUM>. Based on the generated vapor <NUM> impinging upon the additive structure <NUM> outer surface <NUM>, additive release from the additive structure <NUM> into the generated vapor to form a flavored vapor 97a may be improved.
