The present disclosure relates to aerosol delivery devices, and more particularly, to aerosol delivery devices that include a cartridge moveable between multiple configurations relative to a separate housing. The aerosol delivery device includes an atomizer comprising a heating element configured to heat an aerosol precursor. The aerosol precursor composition, which may include components made or derived from tobacco or otherwise incorporate tobacco, is heated by the atomizer to produce an inhalable substance for human consumption.
Many smoking devices have been proposed through the years as improvements upon, or alternatives to, smoking products that require combusting tobacco for use. Many of those devices purportedly have been designed to provide the sensations associated with cigarette, cigar or pipe smoking, but without delivering considerable quantities of incomplete combustion and pyrolysis products that result from the burning of tobacco. To this end, there have been proposed numerous smoking products, flavor generators and medicinal inhalers that utilize electrical energy to vaporize or heat a volatile material, or attempt to provide the sensations of cigarette, cigar or pipe smoking without burning tobacco to a significant degree. See, for example, the various alternative smoking articles, aerosol delivery devices and heat generating sources set forth in the background art described in U.S. Pat. No. 7,726,320 to Robinson et al. and U.S. Pat. No. 8,881,737 to Collett et al., which are incorporated herein by reference. See also, for example, the various types of smoking articles, aerosol delivery devices and electrically-powered heat generating sources referenced by brand name and commercial source in U.S. Pat. Pub. No. 2015/0216232 to Bless et al., which is incorporated herein by reference. Additionally, various types of electrically powered aerosol and vapor delivery devices also have been proposed in U.S. Pat. Pub. Nos. 2014/0096781 to Sears et al. and 2014/0283859 to Minskoff et al., as well as U.S. patent application Ser. No. 14/282,768 to Sears et al., filed May 20, 2014; Ser.

These and other features, aspects, and advantages of the disclosure will be apparent from a reading of the following detailed description together with the accompanying drawings, which are briefly described below.
Having thus described the disclosure in the foregoing general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present disclosure will now be described more fully hereinafter with reference to exemplary embodiments thereof. These exemplary embodiments are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in the specification, and in the appended claims, the singular forms “a”, “an”, “the”, include plural variations unless the context clearly dictates otherwise.
Aerosol delivery devices according to the present disclosure may use electrical energy to heat a material (preferably without combusting the material to any significant degree) to form an inhalable substance; such articles most preferably being sufficiently compact to be considered “hand-held” devices. An aerosol delivery device may provide some or all of the sensations (e.g., inhalation and exhalation rituals, types of tastes or flavors, organoleptic effects, physical feel, use rituals, visual cues such as those provided by visible aerosol, and the like) of smoking a cigarette, cigar, or pipe, without any substantial degree of combustion of any component of that article or device. The aerosol delivery device may not produce smoke in the sense of the aerosol resulting from by-products of combustion or pyrolysis of tobacco, but rather, that the article or device most preferably yields vapors (including vapors within aerosols that can be considered to be visible aerosols that might be considered to be described as smoke-like) resulting from volatilization or vaporization of certain components of the article or device, although in other embodiments the aerosol may not be visible. In highly preferred embodiments, aerosol delivery devices may incorporate tobacco and/or components derived from tobacco. As such, the aerosol delivery device can be characterized as an electronic smoking article such as an electronic cigarette.
Aerosol delivery devices of the present disclosure also can be characterized as being vapor-producing articles or medicament delivery articles. Thus, such articles or devices can be adapted so as to provide one or more substances (e.g., flavors and/or pharmaceutical active ingredients) in an inhalable form or state. For example, inhalable substances can be substantially in the form of a vapor (i.e., a substance that is in the gas phase at a temperature lower than its critical point). Alternatively, inhalable substances can be in the form of an aerosol (i.e., a suspension of fine solid particles or liquid droplets in a gas). For purposes of simplicity, the term “aerosol” as used herein is meant to include vapors, gases and aerosols of a form or type suitable for human inhalation, whether or not visible, and whether or not of a form that might be considered to be smoke-like.
In use, aerosol delivery devices of the present disclosure may be subjected to many of the physical actions employed by an individual in using a traditional type of smoking article (e.g., a cigarette, cigar or pipe that is employed by lighting and inhaling tobacco). For example, an aerosol delivery device of the present disclosure can be hand-held by a user, a user can draw on a portion of the article for inhalation of aerosol produced by that article, a user can take puffs at selected intervals of time, and the like.
Smoking articles of the present disclosure generally include a housing and a number of additional components coupled thereto and/or positioned within the housing, some of the components being movable relative to the housing. The overall design of the housing can vary, and the overall size and shape of the housing can vary. The smoking articles can include a cartridge, which can be defined by an outer body or shell—e.g., an elongated body resembling the shape of a portion of a cigarette or cigar. For example, an outer shell or body of the cartridge can be substantially tubular in shape and, as such, resemble the shape of a conventional cigarette or cigar. In some embodiments, the housing may contain one or more reusable components (e.g., a rechargeable battery and various electronics for controlling the operation of that article), and the cartridge can be removable, refillable, and/or disposable.
Aerosol delivery devices of the present disclosure most preferably comprise some combination of a power source (i.e., an electrical power source), at least one control component (e.g., means for actuating, controlling, regulating and/or ceasing power for heat generation, such as by controlling electrical current flow from the power source to other components of the aerosol delivery device), a heater or heat generation component (e.g., an electrical resistance heating element or component commonly referred to as part of an “atomizer”), and an aerosol precursor composition (e.g., commonly a liquid capable of yielding an aerosol upon application of sufficient heat, such as ingredients commonly referred to as “smoke juice,” “e-liquid” and “e-juice”), and a mouthend region or tip for allowing draw upon the aerosol delivery device for aerosol inhalation (e.g., a defined air flow path through the article such that aerosol generated can be withdrawn therefrom upon draw). When the heating element heats the aerosol precursor composition, an aerosol is formed, released, or generated in a physical form suitable for inhalation by a consumer. It should be noted that the foregoing terms are meant to be interchangeable such that reference to release, releasing, releases, or released includes form or generate, forming or generating, forms or generates, and formed or generated. Specifically, an inhalable substance is released in the form of a vapor or aerosol or mixture thereof.
As noted above, the aerosol delivery device may incorporate a battery or other electrical power source (e.g., a capacitor) to provide current flow sufficient to provide various functionalities to the aerosol delivery device, such as powering of a heater, powering of control systems, powering of indicators, and the like. The power source can take on various embodiments. Preferably, the power source is able to deliver sufficient power to rapidly heat the heating element to provide for aerosol formation and power the aerosol delivery device through use for a desired duration of time. The power source preferably is sized to fit conveniently within the aerosol delivery device so that the aerosol delivery device can be easily handled. Additionally, a preferred power source is of a sufficiently light weight to not detract from a desirable smoking experience. A battery for use in the present devices may be replaceable and/or rechargeable and thus may be combined with any type of recharging technology, including connection to a typical alternating current electrical outlet, connection to a car charger (i.e., a cigarette lighter receptacle), and connection to a computer, such as through a universal serial bus (USB) cable or connector. Examples of electrical power sources are described in U.S. Pat. App. Pub. No. 2010/0028766 to Peckerar et al., the disclosure of which is incorporated herein by reference in its entirety.
An aerosol delivery device according to the present disclosure preferably incorporates a sensor or detector for control of supply of electric power to a heat generation element when aerosol generation is desired (e.g., upon draw during use). As such, for example, there is provided a manner or method for turning off the power supply to the heat generation element when the aerosol generating piece is not be drawn upon during use, and for turning on the power supply to actuate or trigger the generation of heat by the heat generation element during draw. For example, with respect to a flow sensor, representative current regulating components and other current controlling components including various microcontrollers, sensors, and switches for aerosol delivery devices are described in U.S. Pat. No. 4,735,217 to Gerth et al.; U.S. Pat. No. 4,947,874 to Brooks et al.; U.S. Pat. No. 5,372,148 to McCafferty et al.; U.S. Pat. No. 6,040,560 to Fleischhauer et al.; U.S. Pat.

In some embodiments, the aerosol delivery device can include an indicator, which may comprise one or more light emitting diodes. The indicator can be in communication with the control component through a connector circuit and illuminate, for example, during a user draw on the mouthend as detected by the flow sensor.
Various elements that may be included in the housing are described in U.S. App. Pub. No. 2015/0245658 to Worm et al., which is incorporated herein by reference in its entirety.

Various additional examples of heaters and materials employed to form heaters are described in U.S. Pat. No. 8,881,737 to Collett et al., which is incorporated herein by reference, as noted above.
A variety of heater components may be used in the present aerosol delivery device. In various embodiments, one or more microheaters or like solid state heaters may be used. Embodiments of microheaters and atomizers incorporating microheaters suitable for use in the presently disclosed devices are described in U.S. Pat. No. 8,881,737 to Collett et al., which is incorporated herein by reference in its entirety.
One or more heating terminals (e.g., positive and negative terminals) may connect to the heating element so as to form an electrical connection with the power source and/or a terminal may connect to one or more control elements of the aerosol delivery device. Further, various examples of electronic control components and functions performed thereby are described in U.S. Pat. App. Pub. No. 2014/0096781 to Sears et al., which is incorporated herein by reference in its entirety.
Various components of an aerosol delivery device according to the present disclosure can be chosen from components described in the art and commercially available. Reference is made for example to the reservoir and heater system for controllable delivery of multiple aerosolizable materials in an electronic smoking article disclosed in U.S. Pat. App. Pub. No. 2014/0000638 to Sebastian et al., which is incorporated herein by reference in its entirety.
In further embodiments, one or more components of the aerosol delivery device may be formed from one or more carbon materials, which may provide advantages in terms of biodegradability and absence of wires. In this regard, the heating element may comprise carbon foam, the reservoir may comprise carbonized fabric, and graphite may be employed to form an electrical connection with the battery and controller. An example embodiment of a carbon-based cartridge is provided in U.S. Pat. App. Pub. No. 2013/0255702 to Griffith et al., which is incorporated herein by reference in its entirety.
Aerosol delivery devices are often configured in a manner that mimics aspects of certain traditional smoking devices such as cigarettes or cigars. In this regard, aerosol delivery devices typically define a substantially cylindrical configuration. For example, aerosol delivery devices often include a control body and a cartridge which attach in an end-to-end relationship to define the substantially cylindrical configuration. While such configurations may provide a look and feel that is similar to traditional smoking articles, these configurations may suffer from certain detriments. For example, cylindrically-configured aerosol delivery devices may not define attachment points usable to retain the aerosol delivery device in a desired position when not in use. Further, the cylindrical configuration may result in the mouthpiece being exposed to the surrounding environment and therefore susceptible to contamination. Accordingly, it may be desirable to provide aerosol delivery devices in configurations that differ from shapes associated with traditional smoking articles.
In this regard,
As illustrated, in one embodiment the aerosol delivery device 100 may include a housing 102 and a cartridge 200. In some embodiments the cartridge 200 may be moveable with respect to at least a portion of, or an entirety of, the housing 102. In particular, the cartridge 200 may be moveable relative to at least a portion of the housing 102 between a retracted configuration illustrated in
In some embodiments, one or both of the housing 102 and the cartridge 200 may be referred to as being disposable or as being reusable. The aerosol delivery device 100 may include various other components disposed within the housing 102 or the cartridge 200 or otherwise coupled thereto. These components may be distributed between the housing 102 and the cartridge 200 in any of various manners. Accordingly, it should be understood that the described embodiments are provided for example purposes only.
One example embodiment of the cartridge 200 is illustrated in
The base shipping plug 202 may be configured to engage and protect the base 204 prior to use of the cartridge 200. Similarly, the mouthpiece shipping plug 222 may be configured to engage and protect the mouthpiece 220 prior to use of the cartridge 200. The control component terminal 206, the electronic control component 208, the flow tube 210, the atomizer 212, and the reservoir substrate 214 may be retained within the outer body 216. The label 218 may at least partially surround the outer body 216 and include information such as a product identifier thereon.
The atomizer 212 may comprise a first heating terminal 234a and a second heating terminal 234b, a liquid transport element 238 and a heating element 240. In this regard, the reservoir substrate 214 may be configured to hold an aerosol precursor composition. The reservoir substrate 214 is in fluid connection with the liquid transport element 238 so as to transport liquid from the reservoir substrate 214 to the heating element 240 (e.g., via capillary action).
Various other details with respect to the components that may be included in the cartridge 200, are provided, for example, in U.S. Pat. App. Pub. No. 2014/0261495 to Novak et al., which is incorporated herein by reference in its entirety. In this regard,
In another embodiment the cartridge 200 may be substantially similar, or identical, to the cartridge disclosed in U.S. patent application Ser. No. 14/286,552 to Brinkley et al., filed May 23, 2014, which is incorporated herein by reference in its entirety. Thus, for example, the cartridge may include a flow director defining a non-tubular configuration, an electronics compartment sealed with respect to a reservoir compartment, and/or any of the various other features and components disclosed therein. Accordingly, it should be understood that the particular embodiment of the cartridge 200 described herein is provided for example purposes only. In this regard, the cartridge 200 is schematically illustrated in
Similarly, in one embodiment the housing 102 may include some or all of the components of existing embodiments of control bodies configured to engage the above-described cartridge 200 positioned therein or otherwise coupled thereto. For example, the housing 402 may include some or all of the components of the control bodies disclosed in U.S. Pat. App. Pub. Nos. 2014/0261495 to Novak et al. and 2015/0245658 to Worm et al.; and U.S. patent application Ser. No. 14/286,552 to Brinkley et al., filed May 23, 2014, each of which is incorporated herein by reference in its entirety. However, as may be understood, the cartridge 200 may include some or all of these components in other embodiments.
By way of example, in the illustrated embodiment (see, e.g.,
One or more components of the cartridge 200 may be configured to form an electrical connection with the connector 106. For example, referring to the cartridge embodiment of
During use, a user may draw on the mouthpiece 220 of the cartridge 200 of the aerosol delivery device 100. This may pull air through an opening in the connector 106 or in the cartridge 200. However, the flow of air may be received through other parts of the aerosol delivery device 100 in other embodiments. As noted above, in some embodiments the cartridge 200 may include the flow tube 210 (see,
As described below, a sensor in the aerosol delivery device 100 may sense the puff. When the puff is sensed, the controller 108 may direct current to the heating element 240 through a circuit including the first heating terminal 234a and the second heating terminal 234b (see,
In an alternative and optional embodiment, the region of the aerosol delivery device that acts to store or contain fluid that is intended for aerosol formation or for storing an aerosol precursor substance may have the form of at least one capsule or otherwise possess a capsule-type of format and configuration. That is, aerosol precursor composition can be adapted to have a form so as to segregate, or otherwise create physical separation for, that aerosol precursor. In another embodiment the capsule may include a flavorant or flavoring agent in addition to, or alternatively to, the aerosol precursor composition. In an alternative embodiment, the capsule may be in a fluid container that includes the aerosol precursor composition and they are mixed upon activation of the capsule. If desired, a diluent material may be incorporated within the capsule along with the aerosol precursor substance. Representative diluents are set forth in U.S. Pat. No. 8,695,609 to Dube et al.; and 2014/0053855 to Hartman et al., each of which are herein incorporated by reference. Preferably, each capsule is enclosed or sealed in such a way that the aerosol precursor substance does not leak from the capsule or may not be accessible from the capsule, prior to desired conditions of use.
Representative encapsulated components can vary. One example of an encapsulated formulation includes propylene glycol, glycerin, nicotine, organic acids and flavoring agents. An example of a suitable capsule is composed of an outer shell that possesses chemical and physical properties sufficient to provide a sealed container of good integrity for the encapsulated components. For example, such a shell can be provided using components comparable to those used to create capsules employed in filter elements of cigarettes marketed under the brand name “Camel Crush” by R. J. Reynolds Tobacco Company.
A typical capsule-type configuration is provided by an inner region or core of aerosol precursor components, and an outer region or shell that acts as a wall or barrier structure to define the shape and volume of the inner region; as well as entrap, contain or encapsulate the aerosol precursor, thus providing storage or positioning of aerosol precursor in a manner so that the aerosol precursor is physically separated from other components of the aerosol delivery device into which that capsule is incorporated. Preferably, each capsule is enclosed or sealed in such a way that the aerosol precursor substance that is contained therein does not leak from the capsule or may not be accessible from the capsule, prior to desired conditions of use.
Most preferably, a representative capsule is such that the outer shell or wall has sufficient resiliency and integrity to maintain encapsulation of the inner components during normal conditions or storage and handling; but can be broken, opened or activated to release the encapsulated inner components or contents during conditions of normal use. For example, the capsule can be composed of one or more shell materials so as to have a somewhat rigid exterior, or the capsule can have a somewhat flexible overall consistency. The outer wall or shell material of the capsule may be any of the following materials: proteins, polysaccharides, starches, waxes, fats, natural and synthetic polymers, and resins. Exemplary materials for use in the shell may include gelatin, acacia (gum arabic), polyvinyl acetate, potassium alginate, carob bean gum, potassium citrate, carrageenan, potassium polymetaphosphate, citric acid, potassium tripolyphosphate, dextrin, polyvinyl alcohol, povidone, dimethylpolysiloxane, dimethyl silicone, refined paraffin wax, ethylcellulose, bleached shellac, modified food starch, sodium alginate, guar gum, sodium carboxymethylcellulose, hydroxypropyl cellulose, sodium citrate, hydroxypropylmethylcellulose, sodium ferrocyanide, sodium polyphosphates, locust bean gum, methylcellulose, sodium trimetaphosphate, methyl ethyl cellulose, sodium tripolyphosphate, microcrystalline wax, tannic acid, petroleum wax, terpene resin, tragacanth, polyethylene, xanthan gum, and polyethylene glycol. If desired, the capsule can be over-coated with an outer barrier or seal on the outer region with a coating or moisture barrier. U.S. Pat. Pub. No. 2014/0053855 to Hartman et al. further describes capsule materials and is herein incorporated by reference.
Typically, activation is performed by breaking, crushing, or melting of the capsule; and such activation most preferably is initialized by the user of the aerosol delivery device. For example, the user may either press a button or other actuator to provide for movement of components that act to physically destroy the integrity (e.g., provide crushing or piercing) of the capsule, or initiate an electronic signal that can further initiate chemical or physical action upon the capsule. In another embodiment the outer body of the cartridge may be flexible or deformable so as to allow a user to crush the one or more capsules. Additionally, inhalation (i.e. when the flow sensor is triggered) may result in a physical crushing of the capsule by initiation of action of movable components. Furthermore, production of heat during conditions of use of the aerosol delivery device can act to degrade the physical integrity of the capsule wall, and hence release the inner, encapsulated contents of the capsule (e.g., the capsule is positioned in a heat exchange relationship with components of the aerosol delivery device that becomes hot during use, and the resultant heat that the capsule experiences is sufficient to cause a chemical or physical degradation of the capsule shell, hence releasing the sealed contents).
The overall shape of a capsule can vary. Typically, representative capsules are generally spherical in shape. However, the outer shell of the capsule can be adapted to have shapes that can be characterized as being, for example, generally cylindrical, bean-shaped, ovaloid or elongated in nature.
The size of the capsule can vary. For example, a relatively large sized capsule may be employed to replace the reservoir substrate, and in this embodiment the capsule can have an overall size that in comparable to that of the previously described reservoir substrate. In another embodiment the capsule also can be relatively small; and as such, for example, a plurality of microcapsules (e.g., about 50 to about 200 of such small capsules) can be incorporated within each aerosol delivery device. Additionally, spherical capsules having diameters of about 0.5 mm to about 3 mm can be incorporated within each aerosol delivery device; and in such a circumstance, an exemplary aerosol delivery device can incorporate from about one such capsule to about ten capsules.
A capsule most preferably is positioned within the aerosol delivery device such that it can be broken when desired, and such that the contents of the capsule can be made available for aerosol production or for the enhancement of aerosol that is produced by the aerosol delivery device. As such, it is highly preferable, that contents released from the capsule are located in in the vicinity of the wicking components or resistance heating element of the aerosol delivery device (e.g., the capsules can be in contact with, or in a location sufficiently close to, the components of the aerosol delivery device that generate heat or exhibit increased temperature during conditions of use). Thus, the contents of the capsule, which include aerosol precursor components, can be subjected to heat generated for aerosol formation, and hence can be vaporized for aerosol formation. In some embodiments the one or more capsules may be imbedded in, or otherwise coupled to, the wick or the reservoir substrate.
Numerous ways of handling breakable capsules and incorporating those breakable capsules into components of smoking articles and vapor delivery systems have been proposed. For example, various types of capsules suitable for use in smoking articles, smoking article components that incorporate breakable capsules, and equipment and techniques associated with manufacturing those smoking article components, are proposed in U.S. Pat. No. 6,631,722 to MacAdam et al.; U.S. Pat. No. 7,479,098 to Thomas et al.; U.S. Pat. No. 7,833,146 to Deal; U.S. Pat. No. 7,984,719 to Dube et al.; U.S. Pat. No. 7,972,254 to Stokes et al.; U.S. Pat.

No. 9,055,768 to Henley et al.; US Pat. App. Pub. Nos. 2010/0184576 to Prestia et al.; 2011/0053745 to Iliev et al.; 2011/0271968 to Carpenter et al.; to Henley et al. and 2013/0085052 to Novak III, et al.; and U.S. patent application Ser. No. 14/835,962, to Ademe, filed Aug. 26, 2015; which are incorporated herein by reference in their entireties. Additionally, representative cigarette products that possess filter elements incorporating breakable capsules have been marketed throughout the world under the brandnames such as “Marlboro W-Burst 5,” “Kent iSwitch,” “Kool Boost,” “Camel Lights with Menthol Boost,” “Camel Crush,” “Camel Silver Menthol,” “Camel Filters Menthol,” and “Camel Crush Bold.” Furthermore, representative types of vapor delivery systems that incorporate breakable capsules have been proposed in U.S. Pat. Pub. Nos. 2014/0261486 to Potter and 2015/0059780 to Davis; and U.S. patent application Ser. No. 14/282,768 to Sears et al., filed May 20, 2014; which are incorporated herein by reference in their entireties.
Exemplary types of capsules, capsule ingredients, capsule configurations and formats, capsule sizes, capsule properties and capsule preparation techniques are set forth in U.S. Pat. No. 5,223,185 to Takei et al.; U.S. Pat. No. 5,387,093 to Takei; U.S. Pat. No. 5,882,680 to Suzuki et al.; U.S. Pat. No. 6,719,933 to Nakamura et al.; U.S. Pat. No. 7,754,239 to Mane; U.S. Pat. No. 6,949,256 to Fonkwe et al.; U.S. Pat. No. 7,984,719 to Dube et al.; U.S. Pat. No. 8,470,215 to Zhang and U.S. Pat. No. 8,695,609 to Dube; U.S. Pat. App. Pub. Nos. 2004/0224020 to Schoenhard; 2005/0196437 to Bednarz et al.; 2005/0249676 to Scott et al. and 2014/0053855 to Hartmann et al.; and PCT WO 03/009711 to Kim and PCT WO 2014/170947 to Iwatani; which are incorporated herein by reference in their entireties. Additionally, examples of representative types of capsules and capsule components have been commercially available as “Momints” by Yosha! Enterprises, Inc. and “Ice Breakers Liquid Ice” from The Hershey Company; and representative types of capsules and capsule components have been incorporated into chewing gum, such as the type of gum marketed under the tradename “Cinnaburst” by Cadbury Adams USA. Additional disclosure with respect to aerosol delivery devices including capsules is provided in U.S. patent application Ser. No. 14/854,968 to Ampolini et al., filed Sep. 15, 2015, which is incorporated herein by reference in its entirety.
As noted above, the cartridge 200 may be moveable relative to the housing 102. In this regard, the aerosol delivery device 100 may further comprise an actuator 110. In particular, the actuator 110 may be coupled to the connector 106. Thereby, the actuator 110 may be operatively engaged with the cartridge 200 and configured to move the cartridge between the extended configuration and the retracted configuration.
As illustrated in
Conversely, as illustrated in
Thus, in one embodiment the mouthpiece 220 of the cartridge 200 may be at least partially received within the housing 102 in the retracted configuration. In another embodiment an entirety of the cartridge 200 including the mouthpiece 220 may be received within the housing 102 in the retracted configuration. Accordingly, by positioning the mouthpiece 220 relatively closer to the housing 102 (e.g., partially or entirely received therein), the mouthpiece may be protected from damage. Further, the mouthpiece 220 may be less prone to contamination (e.g., from lint, dust, or dirt) in the retracted configuration, which might otherwise transfer to a user's lips or contact the heating element, which could adversely affect performance thereof. Additionally, in the retracted configuration fluid leakage out of the mouthpiece 220 of the cartridge 200 (e.g., condensation) may be captured by the housing 102. For example, fluid leaking from the mouthpiece 220 may drain into a surrounding portion of the housing 102, at which the fluid may be retained and evaporate. In contrast, aerosol delivery devices defining configurations resembling traditional smoking articles typically include a fixedly-positioned mouthpiece, which may be exposed to its surroundings and thereby susceptible to damage or contamination if not properly stored by a user, and which may leak fluid (e.g., condensation) to its surroundings in certain instances.
As noted above, embodiments of the present disclosure relate to aerosol delivery devices that include a cartridge that is moveable with respect to at least a portion of a housing between a retracted configuration and an extended configuration. As further noted above, such aerosol delivery devices may include any of a wide variety of components as described elsewhere herein. However, embodiments of aerosol delivery devices including example configurations of components are described hereinafter. Again, however, it should be understood that the illustrated configurations are provided for example purposes only. Thus, a greater or lesser number of components and/or the same or differing components, which may be distributed between the cartridge and the housing in the same or differing manners, may be included in embodiments of aerosol delivery devices of the present disclosure. By way of further example, in one embodiment the reservoir and/or the heater may be positioned in the housing, rather than in the cartridge. In this embodiment the cartridge may deliver aerosol formed in the housing to the user, rather than produce the formed aerosol. Thus, the cartridge may substantially define a straw, tube, or the like on which the user draws in some embodiments.
However, by way of example,
Additionally, in some embodiments the housing 102 may comprise a front cover 102G and a rear cover 102H. The front cover 102G may define the front 102E of the housing 102. Conversely, the rear cover 102H may define the rear 102F of the housing 102.
Further, the housing 102 may define a width extending between the sides 102C, 102D from about 20 mm to about 60 mm, a thickness extending between the front 102E and the back 102F from about 10 mm to about 50 mm, and a length extending between the bottom 102A and the top 102B from about 40 mm to about 120 mm. In some embodiments, the housing may be expressly non-cylindrical. In contrast, typical aerosol delivery devices configured to resemble traditional smoking articles (e.g., cigarettes) are substantially cylindrical in shape and may define a diameter from about 8 mm to about 15 mm and a longitudinal length from about 80 mm to about 120 mm. Accordingly, the width of the aerosol delivery devices of the present disclosure may be substantially greater than the diameter of traditional aerosol delivery devices in order to improve the level of comfort and secureness of grip associated with grasping the aerosol delivery devices of the present disclosure. Conversely, the length of the aerosol delivery devices of the present disclosure (in the retracted configuration) may be less than the length of traditional aerosol delivery devices in order to improve the portability of the aerosol delivery devices of the present disclosure.
As further illustrated in
The aerosol delivery device 100 may additionally include an input mechanism 114. The input mechanism 114 may comprise a button or switch configured to receive an input from a user. When the input mechanism 114 is actuated, the aerosol delivery device 100 may produce an output corresponding to a status of the aerosol delivery device. For example, the aerosol delivery device may output sound, vibration, or light. As illustrated in
In this regard, the indicator 116 may flash or otherwise illuminate to indicate a remaining or used portion of the capacity of the power source 104 or the reservoir 214 (see, e.g.,
Further in some embodiments the aerosol delivery device 100 may include a display 118, as illustrated in
As previously noted, the actuator 110 may be operatively engaged with the cartridge 200 and configured to move the cartridge between the extended configuration and the retracted configuration. Various embodiments of the actuator 110 may be employed. However, in one embodiment, as illustrated in
The slider 120 may be configured to slide upon a track 122 between the first and second positions. In this regard, a user may slide the slider 120 between the first and second positions via direct or indirect engagement therewith. For example, in the illustrated embodiment the actuator 110 includes an external engagement member 124 (see, e.g.,
The track 122 may guide movement of the slider 120 thereon. The track 122 may restrain motion of the slider 120 such that the slider may move only in first and second directions along the longitudinal length of the track. Various embodiments of the track 122 and the slider 120 may be employed to allow for movement in this manner. However, details with respect to one example embodiment of the track 122 and the slider 120 are illustrated in
As illustrated, the track 122 may define a longitudinal extension 128 and the slider 120 may define a slot 130 configured to receive the longitudinal extension therein. Accordingly, lateral motion of the slider 120, perpendicular to the longitudinal length of the longitudinal extension 128 may be substantially avoided while allowing the slider to move along the longitudinal length thereof. Further, the longitudinal movement of the slider 120 may be limited.
As illustrated in
In order to guide movement of the cartridge 200, in some embodiments the aerosol delivery device 100 may further comprise a guide member 134, as illustrated in
In some embodiments the actuator 110 may define features configured to retain the slider 120 at a selected position along a longitudinal length of the track 122. For example, as illustrated in
A position of the indentation 136 (see,
In other embodiments the indentation 136 and the protrusion 138 may not be included and retention of the slider 120 in a selected position may be caused by frictional engagement between the slider 120 and the track 122. For example, the slot 130 defined by the slider 120 may be dimensioned so as to tightly fit over the longitudinal extension 128 of the track 122 (see, e.g.,
As noted above, the actuator 112 may include the concealment member 126 (see, e.g.,
In this regard, as illustrated in
In this regard, as illustrated in
As illustrated in
In this regard, as illustrated in
The open gap 148 may allow for increased travel of the slider 120 along the track 122 during movement of the cartridge 200 to the extended configuration without requiring a corresponding increase in the longitudinal length of the opening 144 in the concealment member 126 (see, e.g., FIG. 7). In this regard, as illustrated in
Additionally, in some embodiments the concealment member 126 may be configured to slide in first and second opposing longitudinal directions. In this regard, as the slider 120 slides in a first direction to cause the cartridge 200 to move to the extended configuration, the concealment member 126 may also slide in the first direction (e.g., generally to the left in terms of the orientation illustrated in
As noted above, in the retracted configuration (see, e.g.,
As noted above, the aerosol delivery device 100 may employ the connector 106 to cause movement of the cartridge 200 when the actuator 110 is displaced. As illustrated in
In this regard, the connector 106 may be configured to mechanically engage the cartridge 200 such that the cartridge is firmly coupled therewith. Various mechanisms may connect the cartridge 200 to the connector 106 to result in a threaded engagement, a press-fit engagement, an interference fit, a magnetic engagement, or the like. Further, the connector 106 may be configured to form an electrical connection between the cartridge 200 and the controller 108. Thereby, for example, current may be delivered to the atomizer 212 and the electronic control component 208 (see, e.g.,
The connector 106 may include a coupler 150 (see,
Conversely in other embodiments the coupler 150 may be configured to releasably engage the cartridge 200 such that the cartridge may be removed therefrom. Thus, for example, the cartridge 200 may be replaced or removed and refilled when it runs out of the aerosol precursor composition. The coupler 150 may be configured to engage the base 214 (see, e.g.,
With the cartridge 200 coupled to the connector 106, the user may employ the actuator 110 to move the cartridge to the extended configuration (see, e.g.,
As described above, embodiments of the present disclosure relate to aerosol delivery devices that include a cartridge and a housing, wherein the cartridge is moveable with respect to at least a portion of the housing between an extended configuration and a retracted configuration. Thereby, in the retracted configuration the cartridge may be protected, the aerosol delivery device may define a relatively more compact configuration, and/or various other benefits may be provided as described above. Conversely, the extended configuration of the cartridge may allow for a draw thereon and production of aerosol in a substantially conventional manner.
Although an example embodiment of the aerosol delivery device 100 is described above and illustrated in
By way of example,
In one embodiment the slider 520 may be flexible. For example, the slider 520 may comprise a flexible membrane or a plurality of substantially rigid members serially pivotably connected to one another in a manner similar to the cover portion of a roll top desk. Accordingly, when the external engagement member 524 is moved by a user, the slider 520 may change shape based on a shape of a surrounding structure which guides movement thereof. For example, the movement of the slider 520 and the corresponding change in shape thereof may be guided by the housing 502 in one embodiment.
As illustrated in
However, when a user slides the external engagement member 524 (e.g., downwardly in terms of the orientation illustrated in
Additional embodiments of aerosol delivery devices configured to simultaneously open an opening and extend the cartridge therethrough during a transition from a retracted configuration to an extended configuration are also provided. For example,
Thus, as illustrated in
Further,
Conversely, the cartridge 200 may retract back through the opening 754 to a retracted configuration as the moveable portion 702B is rotated to a closed position. Movement of the cartridge 200 in this manner may be caused by a connecting mechanism (e.g., a linkage, not shown) that connects the cartridge to the moveable portion 702B of the housing 702. Accordingly, usage of an actuator, which may comprise a slider or a connecting mechanism, may be employed to simultaneously open an opening and extend a cartridge therethrough, and close an opening and retract the cartridge therethrough, as described above in reference to
Additional embodiments of actuators may be employed in other embodiments. For example,
As illustrated in
An alternate embodiment of an aerosol delivery device 1000 is illustrated in
The housing 1002 may include a main body portion 1002A and a moveable portion 1002B defining a lid. The moveable portion 1002B may be configured to pivot with respect to the main body portion 1002A via a hinge 1056. The cartridge 200 may be configured to remain stationary with respect to the main body portion 1002A of the housing 1002. In this regard, the connector 1006 may be fixedly attached to the main body portion 1002A of the housing 1002.
More particularly, the moveable portion 1002B of the housing 1002 is configured to move with respect to the main body portion 1002A of the housing between a first position (see,
During movement of the moveable portion 1002B the cartridge 200 may be configured to remain stationary with respect to the main body portion 1002A of the housing 1002 while still allowing for transitions of the cartridge between the retracted configuration and the extended configuration in which the mouthpiece 220 is respectively covered and exposed. A user may draw on the mouthpiece 220 of the cartridge 200 when the moveable portion 1002B of the housing 1002 is in the second position (see,
The housing 1102 may include a main body portion 1102A and a moveable portion 1102B defining a lid. The moveable portion 1102B of the housing 1102 may be configured to translate toward and away from the main body portion 1102A of the housing.
