This application claims prior benefit of U.S. provisional application No. 62/081,870, filed on 11/19/2014, which is incorporated herein by reference as if fully set forth herein.

Technical Field

The present invention relates to methods, compositions, and devices for producing functionalized aerosols that mimic the sensory characteristics and properties of mainstream smoke produced by traditional tobacco-based smoking articles.

Background

Electronic cigarettes are a common alternative to traditional smoking articles that burn tobacco products to produce mainstream smoke for inhalation. Unlike traditional tobacco-type smoking articles, electronic cigarettes generate aerosol-based vapors for inhalation, which generally mimic the mainstream smoke of traditional tobacco-type smoking articles. However, it is generally recognized that aerosol-based vapors produced by e-cigarettes do not deliver the same "quality" experience as traditional smoking articles. Applicants have found that this deficiency in the "quality" experience is caused at least in part by the use of a composite aerosol-forming liquid solution to produce an aerosol-based vapor. More specifically, the composite aerosol-forming liquid solution includes an aerosol-forming liquid and one or more taste, flavor, or nicotine delivery components. In addition, it is believed that the use of such composite aerosols to form liquid solutions can result in the formation of chemically or pharmacologically incompatible components. Furthermore, it is believed that interactions between the various components of the composite aerosol-forming liquid solution may cause chemical, pharmacological, and/or thermal instability, which in turn may lead to particle precipitation, fouling of the aerosol heating element, or chemical degradation of the solution, as well as other limitations of aerosol vapor delivery. Each of these drawbacks detracts from the sensory characteristics and quality of the aerosol-based vapor produced by the e-cigarette. Accordingly, it is desirable to provide improved methods, compositions, and devices for generating functionalized aerosols having enhanced organoleptic properties and properties that more closely mimic the smoking experience provided by mainstream smoke from traditional tobacco-based smoking articles.

Detailed Description

According to one aspect of the invention, an aerosol having sensory characteristics suitable for delivery using an e-cigarette is formed using a two-step process. In the first step of the method, an aerosol is formed from an unflavored formulation located within a first chamber or region of an e-cigarette. Any aerosol-forming device (e.g. heated, mechanical, piezoelectric) may be used in the present invention. The aerosol is then subjected to a taste, flavour and/or nicotine carrying substrate suitable for transferring the desired organoleptic properties to the aerosol. During this step, the taste, flavor, and/or nicotine delivery components in the high vapor pressure solvent are released into the aerosol before the aerosol exits the mouthpiece of the e-cigarette. Figure 1 illustrates this two-step process, in which a fragrance insert is used to deliver a fragrance to an e-smoke sol. Another object is to manufacture an electronic cigarette with a removable and replaceable taste functional mouthpiece, wherein the mouthpiece itself may contain functional parts.

The formation of an unflavoured aerosol in an electronic cigarette may involve any known atomizer device. For example, ultrasonic atomization (vibrating with a piezoelectric element and generating high frequency ultrasonic waves to cause vibration and atomization of the liquid formulation), electrospray (with a heating element built on a high surface member in direct contact with the aerosol-forming material), or spray atomization by passing the aerosol solution through a small venturi injection channel. Generally, aerosol characteristics depend on the rheological and thermodynamic properties of the aerosol-forming liquid and the atomizing device. Due to the physicochemical stresses (i.e., thermal degradation, shear-induced phase separation, etc.) of the aerosol-forming material during atomization, the aerosol characteristics and delivery consistency are affected when the liquid is atomized. If the affected aerosol material component is organoleptic, this is closely related to the quality of the aerosol. For example, nicotine may degrade under thermal atomization; menthol and other hydrophobic taste materials may precipitate due to incompatibility with hydrophilic aerosol-forming formulations. In other instances, materials of desirable organoleptic properties, i.e., menthol, tobacco flavors, etc., are insoluble in the aerosol-forming liquid at viscosities and/or surface tensions suitable for delivering acceptable aerosols, thereby limiting the organoleptic properties delivered. Also, this approach can be employed to improve the consistency of aerosol delivery since the absence of sensory material during aerosol formation does not affect viscosity and surface tension. These material variables affect the aerosol particle size distribution. Particularly when it is desired that the aerosol leaving the mouthpiece of an electronic cigarette delivers a consistent amount of nicotine, conducting the aerosol-forming process prior to perfuming can ensure the consistency of the aerosol.

Wherein an unflavored aerosol formulation suitable for forming with particle size distribution and/or density and providing a desired user experience and subsequent sensory profile delivery that can be further tailored, located within the first chamber or first region, is attractive to e-cigarette manufacturers. Base aerosol formulations suitable for use in the present invention include aerosol-forming materials, vapor pressure modifiers, buffers, salts, nucleation site structures, surfactants, preservatives and adjuvants. Moreover, any component that forms an unflavored aerosol formulation can be used to chemically excite another component located downstream of the atomizer. For example, water may be employed to activate an exothermic or endothermic reaction of a salt located in the downstream insert to cause a thermal change that heats the sublimable material insert or alters the deliverable aerosol particle size distribution. Non-limiting examples of unperfumed aerosol-forming formulations are included in table I below.

TABLE I Aerosol formulations

Organoleptically functionalized formulations

Taste, flavour and/or nicotine carrying matrix formulations suitable for use in the present invention to modify the organoleptic properties of the delivered aerosol are given in the embodiments below. These formulations can be liquids, dispersions, gels, encapsulated fragrances, fibers or any other form and shape that allows intimate contact with the unperfumed aerosol stream. These formulations can have high vapor pressures to maximize their flavor contribution to the aerosol stream. Illustrative examples of functionalized formulations that may be incorporated into an electronic cigarette are presented below.

Fragrance delivery

When the preparation is in a liquid state, the main preparation components in this example are composed of a perfume, a vapor pressure modifier, a preservative, and an auxiliary. These formulations also include other components such as surfactants, nucleation sites, buffers, and the like to further modify the delivered aerosol stream. Table II shows non-limiting examples of physical forms of solutions, dispersions, encapsulants and gel formulations. These formulations may contain nicotine as required by the final aerosol delivery specifications.

TABLE II functionalized formulations

Sensory Property flavor delivery with Low solubility/hydrophobicity

When the solubility of the organoleptic material is low, the amount of organoleptic material in the aerosol compatible formulation can be limited. By placing the sensory materials downstream of the e-gas sol formation section, the formulation can be made to have a high concentration of materials that deliver sensory properties, as they are not limited by their low solubility in the aerosol-forming formulation. The formulation components in this example may be comprised of a fragrance, a vapor pressure modifier, a preservative, and an adjuvant. These formulations may also contain other components such as surfactants, nucleation sites, buffers, etc. to further modify the delivered aerosol stream. The following table represents non-limiting examples of liquids, solutions and dispersants.

TABLE III functionalized formulations

Low solubility/hydrophobicity sensory fragrance delivery

A. Chemical/thermal aerosol delivery activity

The present invention also allows for further improvements in aerosol delivery to be obtained because of the benefits arising from their different properties, as two or more chambers, compartments or regions with different formulations are employed in the practice of the invention. These modifications are included for the examples disclosed in tables I, II and III above. Two specific examples are described below:

1. chemical equilibrium or chemical reactivity

According to this embodiment, the unflavored preparation may contain a chemical component that may react with or affect another chemical component comprised by the downstream functionalized formulation. For example, it is known according to

Acid/base theory, nicotine in solution is chemically balanced. Thus, acidic or basic components carried by unflavored aerosols, such as buffers of acetic acid, citric acid, and the like, can be used to control the ionization of nicotine in the final delivery aerosol. Wherein according to this embodiment nicotine delivery consistency can be improved. In addition, in situ formation of the friable flavor and taste components is possible if the reactants are kept separate until mixed within the aerosol vapor prior to delivery.

2. Thermal activity

A chemical component that can react with another chemical component contained in a downstream formulation is included in the unflavored formulation to exothermically or endothermically alter the temperature of the aerosol. For example, water in the unflavoured aerosol may react with salt compartments in the downstream portion of the e-cigarette to release heat generated by hydration of iron, manganese salts, caO, etc. that are food grade. The heat may be used to promote sensory sublimation of downstream portions of the e-cigarette. Another example is the use of an endothermic reaction, i.e. food grade NH4Cl or the like. This allows the aerosol vapour to be cooled after its formation and thus improves the delivery consistency of the aerosol particle size distribution.

Figure 2 further illustrates the concept whereby an aerosol-forming liquid is contacted with a heating element in the aerosol-forming cartridge, thereby forming an unflavoured aerosol in the aerosol-forming cartridge. As the aerosol moves downstream and interacts with the fragrance insert, the aerosol becomes scented. Although the sketch in figure 2 shows the main components of a separate e-cigarette, it will be appreciated that any combination of battery, aerosol can and/or flavour insert may be physically integrated with each other as long as the flavour insert is located downstream of the aerosol can as indicated by the arrow.

This concept separates aerosol formation from the delivery of taste, aroma and/or nicotine. Thus, the aerosol may be improved by eliminating any degradation in quality, nicotine delivery and taste caused by the interaction of the aerosol-forming liquid formulation with the formulation contained in the flavour insert or by thermal degradation/deactivation thereof upon contact with the heating element of an electronic cigarette.

In addition, the fragrance formulation within the insert may be made from a wide range of materials such as conventional solutions, dispersions, emulsions, gels, creams, powders, pastes, waxes, and the like. Fragrance release can occur thermally, chemically, by dissolution, vapor pressure driven, humidified, electrically, and the like. The insert may use a combination of one or more fragrance bases such as surface coatings, dissolvable and non-dissolvable matrices, encapsulated fragrances, fibers, porous materials, wicking networks, coated networks, and the like.

Although this concept is based on aerosol hydrodynamics, it can be further enhanced by placing a heating element within the insert to control the scent release.

The embodiment of the device of the present invention described below in figure 3 comprises an electronic cigarette having a mouthpiece loaded with a glycol/water solution in addition to a cellulose acetate insert coated with tobacco flavor located in front of the mouth end. The aerosol delivered under this structure is called "tobacco flavored aerosol". As a further example, a vanilla flavoured insert may be employed to deliver vanilla flavourant to the aerosol.

The sketches demonstrated in the following figures show a number of embodiments of the proposed insert for implementing the invention. These embodiments are non-limiting, and it is to be understood that the invention may include a combination of one or more of these embodiments, which may be integrated into an e-cigarette or manufactured in a modular or removable manner.

Filled with flavouring agentsPorous matrix for implantation of coated or hollow fibers

FIG. 4 shows an embodiment of the invention comprising a flavor formulation within a porous matrix of embedded fibers. The flavor can be coated on the fibers for inclusion within the hollow fibers. According to this embodiment, fragrance is passed into the aerosol stream to perfume the aerosol stream. It can be selectively activated electrically or by dissolving the fragrance carrier. A similar release mechanism may be applied to many other embodiments described below.

Single/multi-layer screen insert wherein the screen carries a fragrance as a coated fiber, a fragrance as an encapsulated fiber And the like.

Figure 5 shows an embodiment of the present invention comprising a fragrance embedded within a single or multi-layer mesh for delivery to an unflavored aerosol vapor. According to the present invention, the release of e.g. encapsulated perfume may be activated by water/glycol in an unflavored aerosol formulation.

Woven or non-woven web or sheet form made of an erodable material or any of the aforementioned fragrance carriers

Figure 6 shows an embodiment of the present invention comprising a composite web that allows for the release of fragrance upon interaction with an unflavored aerosol.

Diffusible and/or erodable disc

Fig. 7 shows an embodiment of the invention comprising a diffusible or erodible disc containing a functionalized formulation. For example, the disc is formulated with a fragrance in a hygroscopic base that corrodes during inhalation.

Coil winding insert with high coating area or web structure

Fig. 8 illustrates an embodiment of the present invention including a coil wound insert with a coated area or mesh structure. The objective of the present design is to maximize the effective interaction between the unflavored aerosol and the fragrance insert. This design is also applicable to several embodiments disclosed herein.

Porous membranes or open-cell foams/sponges

Figure 9 shows an embodiment of the present invention involving the use of a porous membrane or open-cell foam/sponge structure. The porous membrane may be made of cellulose or any other highly absorbent material that can be used to carry flavors/nicotine. The electronic cigarette with the tobacco flavor-embedding material towards the mouth end shown in figure 3 is one embodiment of the present design.

Braided fragrance coating insert

Fig. 10 shows a fragrance coating insert comprising a braid, according to an embodiment of the invention. In addition to maximizing the area of effective interaction of the unflavored aerosol with the fragrance insert, this braided design benefits from venturi acceleration to drive the fragrance into the aerosol flow.

Three-dimensional fragrance coating insert

Fig. 11 shows a fragrance coating insert including a configuration according to an embodiment of the invention. In addition to being readily formed into a solid insert, the insert may also be made from a corrodible flavor/nicotine base. One or more flow paths can be employed to control flow dynamics and maximize the impact energy of the unflavored aerosol on the fragrance insert.

Tube bundle

Figure 12 shows a tube bundle containing flavors/nicotine releasable under different pressures, temperatures or electrical activation according to one embodiment of the present invention. The force of inhalation may also be the force of fragrance release.

Flavor/nicotine coated channels in honeycomb insert

Figure 13 shows an embodiment of the invention comprising a honeycomb cell structure with flavor/nicotine compartments. The release may be controlled by different release rates distributed in the cell. The concept of controlling the rate of fragrance release by varying the rate of activation of the entire fragrance insert is also applicable to other embodiments of the present invention.

Release of fragrance by inhalation-I

Figure 14 shows an embodiment of the invention comprising a flavor/nicotine containing capsule which releases its loading under inhalation pressure. The method can be used as an OFF/ON fragrance option to change fragrance. Although fig. 14 shows the taste of an unflavored aerosol stream, it can also be used to alter the taste of a fragranced aerosol stream. The insert is then used. These concepts may also be applied to the following embodiments where the scent is released by inhalation or by physical crushing.

Releasing flavour-II by inhalation or physical crushing

Figure 15 shows an embodiment of the invention comprising a flavour insert which can be ruptured under inhalation pressure or ruptured by physical crushing to release flavour into an aerosol stream.

Fragrance releasing nonwoven mesh/woven mesh bag

Figure 16 shows an embodiment of the present invention comprising a nonwoven mesh bag with a nonwoven sensitive material that typically has interstices through which smoke can pass when activated. The web is compressed and bonded while compressed to maintain the fibers in a compressed state to fill the interstices and prevent outward loss of their load. The payload can be a flavor, tobacco flavor, nicotine delivery enhancing chemical, or other desired material to modify the unflavored aerosol. The bag releases its load when punctured. The web can react with or dissolve one or more chemical components of the unflavored aerosol to be activated. Thus, the packaged formulations provide the benefit of improved shelf life by not interacting with the environment and protecting each other prior to use.

Fragrance releasing bag

Fig. 17 and 18 show an embodiment of the invention comprising a bag containing an effective loading substance. The loading substance can be a flavor, tobacco flavor, nicotine delivery enhancing chemical, or other desired material to modify the organoleptic properties of the aerosol. The bag releases its load to a mechanical device, a heat activated device or similar mixing device under the action of, for example, a puncture, a break, an open valve, etc. With the pouched formulation located within a sealed container, the user can use the ON/OFF option to adjust the aerosol sensory experience. The invention includes the use of multiple pockets or chambers placed in a carousel device aligned with the aerosol flow so that a user can select a particular flavourant to be delivered when using an e-cigarette. In addition, the formulations provide the benefit of improved shelf life by not interacting with the environment and protecting each other prior to use.

The user may then place the desired removable insert in the second portion, attach the mouthpiece to the second portion and use the e-cigarette. The removable insert may include at least one flavorant, a desired level of nicotine, or both. If the user desires a different flavor or nicotine content, they may remove the mouthpiece from the e-cigarette, remove the insert and place a new insert into the second portion. Once the user has exhausted the aerosol-forming substance within the second portion, the second portion may be thrown away or recycled and a new second portion attached to the rechargeable battery.
