FIELD OF THE INVENTION
The present application provides a dual functioning volatile medium delivery system.
BACKGROUND OF THE INVENTION
A number of methods exist for dispensing a volatile fragrance material into the air in order to create a pleasant indoor fragrance experience and/or for the purpose of counteracting or neutralizing offensive odors. Previous methods utilizing vessels made from porous materials such as ceramic, have been used as a means to provide fragrance dispersion. Typically, these products are offered with a pre-measured amount of fragrance which is simply poured into the vessel in order to initiate activation. Migration of the fluid fragrance into the absorbent vessel completes the process. A glazing on the outside of the vessel protects surfaces from unwanted exposure to the fragrance.
Previously, there have been devices created to combine various technologies with candles, saturated papers, gels of varying compositions, and liquid wick diffusers. Some of such devices have been created for distributing fragrance. The units employing these varying methodologies are generally singularly-purposed, stand-alone devices devoted to the sole purpose of fragrance dispersal.
Most commonly the candle has been used as a heat source to evaporate the volatiles from gels, liquids, waxes on absorbent substrates that are positioned above the flame or in close proximity to it. Although being effective to an extent, these devices also suffer from being fully functional only while the candle is lit.
Gels, although continuous in their odor producing capabilities, have frequently lacked a sustainable fragrance intensity that is consistent throughout their functional lives. The performance profile for gels typically generates good fragrance awareness early; however, this odor awareness dissipates quickly to imperceptible levels shortly after activation. This inconsistent performance by gels has been a significant drawback to their success in the marketplace.
Both candles and gels offer economic methodologies for use as fragrance dispersion mediums and if their performances could be improved, a much wider acceptance of the forms of air freshening would be achieved.
Candles, while offering a relatively inexpensive means to achieve fragrance dispersion, exhibit limitations preventing them from effectively operating in a continuous manner. The volatilization of fugitive fragrance materials occurs primarily when the candle is lit and the candle composition is melted to create a molten pool. The elevated temperature that occurs in this pool hastens the diffusion of the volatiles into the surrounding environment. Very little fragrance is emitted from the candle when it is not lit, only that which is available from any of the candle's exposed surfaces.
Candles are generally not continuously operational throughout their lifetimes. This is largely because of the safety concern created by having an unsupervised open flame. In addition, the continuous operation would greatly reduce the functional life of the candle. In the case of creating a continuous indoor fragrance experience, the intermittent operation of the candle does not allow for the sufficient release of volatiles to create a seamless fragrance impression.
There remains a need in the art to combine a device intended to diffuse compositions of volatile mixtures and to integrate this form into a device capable of supporting either fragranced or non-fragranced articles. Accordingly, there is a need and desire for a dual-functioning volatile medium delivery system capable of emitting volatile mediums, for example a fragrance, in addition to providing an article that benefits from a union with the porous emanator.

DETAILED DESCRIPTION
One or more objects of the present application are accomplished by the provision of a dual-functioning volatile medium delivery device. The creation of systems according to the disclosed subject matter allows for the combined benefit of a volatile medium diffusing methodology in combination with a container, vessel, design element, or additional volatile medium diffusing device to broaden the appeal of such a device. The use of a fragrance diffusing device in combination of an additional fragrance medium of some type would serve to augment the fragrance awareness created by that medium, whereas when used with articles that are unfragranced, the device serves as a primary source of fragrance emanation and creates a unique indoor odor experience.
The disclosed subject matter generally includes:

    
    
        (a) a reservoir containing a volatile medium; and
        (b) an emanating element including an exposed emanating surface and a wicking extension, the emanating element being adapted to engage the reservoir.
    
    


The emanating element can have a wide variety of shapes and constructions. For purposes of explanation and not limitation, the emanating element can include, for example, an element capable of serving as both an emanator and a container (e.g., a porous vessel) or a cradle capable of engaging with a tertiary element such as a decorative article, a functional article, or a substance-containing article. As such, the volatile medium delivery device according to the disclosed subject matter can be a two-piece construction. For example, in one embodiment, a dual-purpose fragrance delivery system can include:

    
    
        (a) a vessel either wholly or partially fabricated from a porous composition and having a porous surface;
        (b) a first fragrance medium, such as a candle, capable of being housed in the fragrance delivery system and;
        (c) a second fragrance medium, such as a gel or liquid fragrance composition, that is capable of being loaded within in a reservoir of the fragrance delivery system;
        (d) at least one wicking extension from the porous surface of the vessel located at or near its base that extends downward for eventual engagement with the reservoir and capable of wicking the contents of the reservoir.
    
    


The volatile medium delivery device can also be constructed from three (or more) pieces. For example, in one embodiment, a three-piece delivery system can include:

    
    
        (a) an article;
        (b) a cradle including an exposed emanating surface and a wicking extension, the cradle being adapted to engage the article; and
        (c) a reservoir containing a volatile medium and adapted to engage the cradle.
    
    


In various embodiments, the reservoir can be a detachable reservoir base sized such that it can accept the full contents of the fluid reservoir composition as well as the extensions of the vessel. Preferably the extension that will rest within the confines of the base and have intimate and complete contact with the contents of the reservoir. The vessel can be a hollow vessel, and the hollow vessel can be optionally be further loaded with a third fragrance medium, such as polymeric beads.
In one embodiment, a liquid or gel fragrance composition is charged into the reservoir base and the hollow vessel is oriented directly over, or substantially directly over, said base with the porous extensions at least partially disposed in the liquid or gel fragrance composition. Preferably, the vessel is lowered onto the loaded reservoir base until it comes to engage the base with the wicking extensions resting on the bottom of the reservoir base. In various embodiments, the vessel is additionally supported by the engagement of the elevated sidewalls of the reservoir base with an accepting recess formed into the side of the vessel. The fluid reservoir composition first enters the porous extensions of the vessel for evaporation into the atmosphere from the porous surface of the vessel. Fragrance is also dispersed from the first fragrance medium (e.g., a gel or candle contained within the void of the vessel interior), creating a dually sourced fragrance dispenser.
Thus, in various embodiments, the dual functioning fragrance delivery system of the present application offers the advantage of being able to serve as the container for a first fragrance medium such as a gel composition or candle, while at the same time providing a source for a second, independent fragrance medium, such as a liquid composition (e.g., essential oils) or, in alternative embodiments, a solid fragrance composition (e.g., potpourri). In some embodiments, the fragrance emitted from the first fragrance medium, and the fragrance emitted from the second fragrance medium, while pleasing alone, are, as combined, designed to provide a synergistically pleasing fragrance to a consumer.
In embodiments in which the second fragrance medium includes a liquid or otherwise diffusible fragrance composition, the partial immersion of the vessel into the detachable reservoir base that contains the second fragrance composition (e.g., a fluid reservoir fragrance composition) results in the transfer of the second fragrance composition into the absorbent porous surfaces of the vessel which holds the first fragrance composition. In various embodiments, evaporation of the fugitive fragrance materials (i.e., the second fragrance composition) from the porous surface of the vessel results in a very effective fragrance dispersion method.
The combination of fragrance diffusion from the surface of the vessel as well as that emanating from first fragrance composition contained within the vessel offers significant advantages as compared to those fragrance dispersion methods that rely on a single source.
The application will now be described in reference to the drawings. FIG. 1 depicts an embodiment of the present application (1000). The exploded crosscut view of the unit depicted in FIG. 1 provides a candle (60) as the first fragrance medium which is supported on a reservoir that forms the base (80) of the device.
The unit includes a hollow vessel (10) made from a porous material such as ceramic. Other non-limiting examples of the hollow vessel material, besides a ceramic, include, but are not limited to terracotta, clay earthenware, concrete and porcelain. A glazed coating can be applied to the surface of vessel, including a glazed interior coating (20) and a glazed exterior coating (40) that can be positioned so as to allow a consumer to handle the vessel without coming into contact with the contents of the reservoir that will diffuse into the porous sidewalls of the vessel (30).
A candle wick (50) is centrally positioned in the vessel prior to the loading of the molten candle composition which forms a candle (60) upon cooling (e.g., a solid or semi-solid candle upon cooling). Wicking extensions (70) protrude downward from the base of the vessel and are generally along the same plane as the vessel's sidewalls (30).
A detachable reservoir base (80), upon which the vessel rests, is composed of a material such that when the liquid reservoir composition is loaded into it, and there is no permeation through the reservoir base. Suitable compositions for said base would include, but are not limited to, any porous materials with a glaze applied thereto, such as a glazed ceramic, terracotta, clay earthenware, concrete or porcelain substrate. Thermoplastic or thermoformed compositions such as, but not limited to, polypropylene, polyethylene, polyethylene terephthalate and the like, would also prove a suitable material for the reservoir base.
The reservoir base (80) is sized proportionately to receive the full amount of the fluid reservoir composition, as well as be sufficiently sized to accept the wicking extensions (70) protruding from the base of the vessel. The upper lip of the reservoir base (90) can engaged into a recess (100) formed in the body of the vessel to accept it.
The reservoir base (80) can be optionally provided with an elevated interior center so as to yield a domed convex surface (110). This elevated center gradually tapers down to the channel edge (120) of the recessed channel (130).
FIG. 2 is an enlarged crosscut view (2000) of the base of the device of FIG. 1, which includes a recessed channel (130) that fully circumscribes the outermost circumference of the reservoir base (80) and is of sufficient width to have the wicking extensions (70) reside in the recess formed by the recessed channel (130) and to rest in flush contact with the bottom reservoir base. Alternatively, the wicking extensions can be sized so as to, when fully engaged, rest short of the bottom of the reservoir base, although it is preferred that the wicking extensions rest on the recessed channel itself when fully engaged.
The convexed surface (110) of the reservoir base center will direct the fluid reservoir composition (not shown) toward the wicking extensions (70) and maximize the contact between the wicking extensions and the reservoir fluid. A channel edge (120) is also provided, and preferably spaced at such a distance to engage the wicking extension.
FIG. 2 also shows a detailed view of the hollow vessel (10) containing porous vessel sidewalls (30). A recess (100) is provided along the bottom of the hollow vessel for engagement with the reservoir base upper lip (90).
FIG. 3 is a crosscut view (3000) depicting the engagement of the hollow vessel (10) with the reservoir base (80) after the liquid reservoir composition (140) has been loaded into the reservoir base in a separate process (not shown). The engaging of the vessel (10) with the reservoir base (80) will cause the wicking extensions (70) to rest in the recessed channel (130) formed to accept them and to come into intimate contact with the reservoir liquid composition (140). Migration of the fragrance composition out of the reservoir base (80) and into the vessel's porous absorbent sidewalls (30) will continue until the reservoir fluid in the reservoir base is depleted or until the vessel's sidewalls (30) are fully saturated.
The diffusion of the volatile components of the reservoir composition (140), the result of their exposure to the expanded surface offered by the vessel's porous sidewalls (30), results in a highly effective emanating process for the creation of a fragranced indoor environment.
FIG. 3 also depicts a recess (100) which serves to position the wicking extension (70) inside the sidewall of the reservoir base (80) and within the recessed channel edge (120). The reservoir base is provided with a convex surface (110) along the bottom of the reservoir in order to direct the reservoir liquid composition (140) to the wicking extensions (70). The hollow vessel, which is porous, is coated with a glazed coating exterior (40) and a glazed coating interior (20) for purposes of aesthetics and to facilitate handling of the device. Although this device is shown with a candle (60) and candle wick (50), the hollow vessel (10) can alternatively hold, for example, a gel composition as an independent fragrance medium in addition to the reservoir liquid composition (140).
Correspondingly, the ability to create an intense fragrance environment is additionally supported by the use of the candle contained within the vessel as an additional means to achieve fragrance diffusion. The dual benefit derived by having two independent sources of fragrance in a single unit results in performance characteristics that are superior to those generated from either one of these methodologies being used exclusive of the other.
The exploded crosscut view of the unit (4000) depicted in FIG. 4 shows a hollow vessel (10) made from a porous material such as ceramic. The wicking extensions (70) are again shown at the base of the vessel (10) and are continuous with the porous vessel's sidewalls (30), but oriented inside the sidewalls due the recess (100).
The hollow vessel (10) in this embodiment can be used as a container for a fragranced gel composition (150). Fragranced air freshening gels can be formed by the use of either naturally derived hydrocolloids such as carrageenan or gellan gums for use in aqueous based compositions, metallic salts such as sodium stearate for water, glycol compositions, or through the use of synthetic polymers such as thermoplastic elastomers, polyurethane and polyamides, for anhydrous or substantially anhydrous fragrance solvent systems. Alternatively, another fragrance medium could be housed in the hollow vessel, such as, but not limited to, potpourri, fragranced soaps, and fragranced polymer beads.
The gels can be poured into the hollow vessel either as heated liquefied fluids such that upon cooling they set into a final solid or semi-solid form or they can be poured at ambient temperature and through a cross-linking process develop into their final gel-like consistency over a period of time.
The vessel (10) is glazed with an impervious glazed surface coating (20) covering the interior of the vessel to provide an aesthetically appealing appearance. A portion of the glazing (40) is also used on the outer surface of the vessel to facilitate handling. The gel composition (150) is loaded into the hollow vessel (10) and allowed to set until such time as the gel achieves its final, desired consistency.
FIG. 5 depicts a close-up view of the reservoir insert (160) also shown in FIG. 4, which is provided with a rupturable top foil seal (180) and a rupturable bottom foil seal (185). Reservoir insert (160) can be made of, for example a thermoplastic, which can be prepared, for example, by injection molding or thermoforming processes known to those of ordinary skill in the art. The cavity (170) formed in the reservoir insert (160) is sized such that it is capable of containing the full measure of the liquid reservoir composition (140). The reservoir is formed with two openings. A heat sealable material (185) that is capable of being ruptured is sealed over the narrower of the two openings (190). The liquid fragrance reservoir composition (140) is then loaded into the cavity (170) via filling through the larger opening (200).
Once the reservoir container is loaded, a heat sealable material (180) is affixed over the larger opening (20), sealing the fragrance composition (140) within the cavity (170). The reservoir container can then be adhesively or mechanically inserted into the space formed in the vessel (10) to accept it as depicted in FIG. 8.
Referring back to FIG. 4, the reservoir insert (160) is oriented such that the narrow opening (190) is directed towards the reservoir base (80). The reservoir base (80) provides a domed convex center (110) on top of which is a piercing lance (210). This piercing lance (210) is ideally formed as part of the injection molding process used to manufacture the reservoir base (80). The reservoir base (80) also exhibits in this embodiment a tear-away band (220) that runs continuously around the top of the reservoir base (80) and is formed as part of the same injection molding process in which the reservoir base (80) is formed. The tear-away band (220) serves the function of keeping the piercing lance (210) from contacting the reservoir insert (160) positioned above it and causing unwanted activation of the unit. Removal of the tear-away band (220) allows the reservoir base (80) to travel upward such the recess (100) will rest on the reservoir upper lip (90) and so that the piercing lance (210) can now engage the foil seal (not shown in FIG. 4) covering the narrow opening (190) of the reservoir insert (160).
Activation of the unit is effected when the hollow vessel (10) is forcibly engaged with the reservoir base (80) and in the process causing the piercing lance (210) to rupture the foil seal (180) oriented above it and thereby allowing the fluid contents (140) of the reservoir insert (160) to drain into the reservoir base (80). The fluid fragrance composition will then come in intimate contact with the wicking extensions (70). Positioning of the wicking extension within the base is added by a recessed channel in the base (130) which is provided with a recessed channel edge (120).
The reservoir liquid composition will absorb upwards into the absorbent porous surfaces of the hollow vessel (10). Fragrance is then dispersed into the surrounding environment by the evaporation of the volatile components from the surfaces of the vessel. Fragrance diffusion is augmented by the contribution of the fragranced gel contained within the hollow vessel.
FIG. 7 depicts another device (7000) that is provided with a reservoir insert (160) secured to the bottom of the hollow vessel (10) and positioned for ultimate engagement with a piercing lance (210). The reservoir insert can be secured to the bottom of the vessel by any appropriate means known to those of ordinary skill in the art. Due to the recess (100), the wicking extensions (70) fit just inside the sidewalls of the reservoir base. Upon removing the tear away band (220), the recess (100) will rest on the reservoir base upper lip (90), and the wicking extensions will be disposed in the recessed channel (130) which is provided along the periphery of the bottom of the reservoir base. Prior to removing the tear away band, the sealed bottom of the reservoir insert (180) does not engage with the piercing lance, and the contents of the reservoir insert remain inside. The bottom of the reservoir base is provided with a convex surface (110) so that, once deployed, the reservoir liquid composition will be directed towards the recessed channel and wicking extensions.
Although the device of FIG. 7 is shown with a gel composition (150), other fragrance mediums can be housed in the hollow vessel. In some embodiments the reservoir liquid composition (140), which will diffuse out of the porous vessel sidewall (30), is designed to synergistically interact with the gel composition (150) to provide a pleasing, long-lasting fragrance to the ambient space around the device. As discussed above, the device is provided with a glazed coating interior (20) and exterior (40).
FIG. 8 provides another view of a device (8000) that is provided with a reservoir insert (160). As shown, the reservoir liquid composition (140) has been deployed, as the piercing lance (210) has ruptured the foil seal (180). The device is also provided with a hollow vessel (10), having a porous sidewall (30) and loaded with a gel composition (150), glazed coating along portions of the interior (20) and exterior (40), wicking extensions (70), a reservoir base (80) with a convex bottom surface (110), and a recessed channel (130).
An additional embodiment of a fragrance delivery device (9000) according to the present application is depicted in FIG. 9. This embodiment provides a dual cavity reservoir insert (230) capable of containing the reservoir composition (140) of a single fragrance or that of two different fragrances in the cavities (170) of the dual cavity reservoir insert (230). One benefit of having a reservoir insert capable of containing two fragrance compositions is that, as the fragrance emanation generated by the fragrance composition contained in the first reservoir dissipates over time, the contents of the second cavity can be released to renew the scent producing characteristics of the unit. The option of using two different fragrances in the dual cavity reservoir insert (230), in addition to the independent fragrance medium contained in the hollow vessel (10) (here a gel composition (150)), affords the user a more varied fragrance experience.
The device of FIG. 9 also contains a glazed coating along portions of the exterior (40), and interior (20) of the porous vessel sidewall (30). Also provided is a narrow opening (190), capped with a foil seal (180). Wicking extensions (70), sized to engage with a recessed channel (130), formed with a recessed channel edge (120) is also provided. The reservoir base (80) is provided with a reservoir base upper lip (90) and a convex surface (110) along the bottom to direct the reservoir liquid composition, once employed, to the recessed channel.
Referring now to FIG. 6, a dual cavity reservoir insert (230) according to one embodiment of the present application is formed from a thermoplastic material. The thermoplastic material can be manufactured, for example, by an injection molding or thermoforming process. The dual cavity reservoir insert (230) is formed with four openings defining the formation of two cavities (170). The narrower openings (190) are closed with a heat sealable, rupturable foil seal material (180). The reservoir liquid composition (140) is loaded into the cavities (170) and a heat sealable top foil seal covering (185) is used to close the larger openings (200). The dual cavity reservoir insert (230) is then affixed to the base of the vessel and oriented with the narrow openings (190) directed towards the reservoir base.
Referring now to FIG. 9, once the tear-away band (220) is removed, the engagement of the hollow vessel (10) with the reservoir base (80) results in the rupturing of the foil closure (180) by the piercing lance (210).
In this embodiment, since the narrow cavity openings (190) are off center, the piercing lance (210) is also positioned off center to engage the openings. The option of rotating the reservoir base (80) to have the piercing lance (210) positioned properly to rupture the seal of the second cavity would require that only one piercing lance (210) be molded into the reservoir base (80).
The exploded crosscut view of FIG. 10 depicts a vessel created with both a porous sidewall component (240) and a non-porous sidewall component (250) which when joined together form a complete vessel capable of containing an independent fragrance medium, such as a candle or gel as described in the previous embodiments.
An advantage of the embodiment shown in FIG. 10 is that in all prior embodiments, the hollow vessel, or at least the substrate of the hollow vessel, was exclusively porous. The current embodiment offers the option of creating a vessel in which at least a portion of which is fabricated from materials which are not porous such as, but not limited to, metal, glass, a thermoplastic, and the like.
The ability to insert a segment of the vessel fabricated from a porous composition such as ceramic, terracotta, clay earthenware, concrete, porcelain into a partially formed vessel fabricated from non-porous materials offers flexibility in the creation of unique diffusing devices.
Previous embodiments disclose the use of materials which are and opaque. In the current embodiment the option now exists to create a container fabricated from transparent or translucent glass in combination with a portion fabricated from a porous material. This offers many advantages especially when the vessel is used as container for a fragranced candle.
As depicted in FIG. 10 there is a portion of a container (10,000) manufactured from a non-porous sidewall composition (250) such as glass or a metal. A portion of the container is also depicted as being made with a porous sidewall (240) such as terracotta.
The porous sidewall components and the nonporous sidewall components could be slideably engaged or they could be mechanically joined by inserting them in the reservoir base (80) and using a binding collar (260) which slips over the top of the vessel to keep the sections in locking contact.
It is important that the union between the two components have sufficient integrity so as to contain the contents of the air freshening composition fluidly filled into the vessel (here, a candle (60) with a wick (50)) and until such time as this composition develops the consistency of its final form.
The interior surface of the porous sidewall component (240) of the vessel is provided with a glazed coating (20) on its interior surface to prevent the air freshening medium poured into the vessel (e.g., a candle) from penetrating the absorbent porous composition of this component.
The porous sidewall component (240) of the vessel also differs from the non-porous sidewall component (250) in that there are wicking extensions (70) which extend downward from the porous sidewall component (240) into the detachable reservoir base (80) of the unit. As opposed to a convex surface, a slanted surface (270) is provided along the bottom of the base to direct the liquid fragrance composition housed in reservoir base to the wicking extension that extends from the porous side wall component. The reservoir base (80) is also provided with a reservoir base upper lip (90) and a recessed channel (130). A recess (100) is also provided in the hollow vessel so as to properly position the sidewall component within the reservoir base.
FIG. 10 depicts the engagement of the composite hollow vessel (10) with the wicking extensions (70) fully residing in the recessed channel (130) formed to accept them. The liquid reservoir composition (140) has been loaded into the reservoir base (80) in a separate loading process.
The liquid reservoir composition (140) now in contact with the wicking extensions (70) can freely migrate up into the porous surfaces of the porous sidewall component (240) of the vessel for eventual evaporation. Complete contact between the fluid reservoir composition (140) and the wicking extension (70) in the reservoir base (80) is facilitated by the slanted surface (270) on the interior of the reservoir base (80) which directs the fluid contents of the reservoir base (80) towards the recessed channel (130) for continuous contact with the wicking extension (70).
In the event that the liquid reservoir composition (140) is in excess such that the porous component (240) of the vessel becomes saturated before all of the reservoir fluid migrates out of the reservoir base (80), the porous sidewall component (240) of the vessel will be continually replenished with the reservoir composition as the surface of the porous sidewall component (240) becomes depleted and accepting of replenishment in a continuous wicking process. This process will continue until such time as the liquid fragrance composition (140) constituting the fluid reservoir is fully evacuated from the reservoir base (80).
Another unit (11,000) according to one embodiment of the present application is shown in FIG. 11. A hollow vessel (10) is provided containing a candle (60) and candle wick (50). As in FIG. 10, a porous sidewall components (240) and nonporous sidewall component (250) is provided. A wicking extension (70) extends from the porous sidewall component. Recesses (100) are provided for both sidewall components for proper positioning of the wicking extension (70) and an extension (75) from the nonporous sidewall component with the reservoir base (80). A binding collar (260) is provided to maintain structural integrity between the porous sidewall component and the nonporous sidewall component. The reservoir base (80) is provided with a reservoir base upper lip (90), a recessed channel (130) and a slanted surface (270).
FIG. 12 depicts an embodiment (12,000) of the present application in which the hollow vessel (10) includes both a porous sidewall component (240) and a nonporous sidewall component (250). A binding collar (260) joins the porous sidewall component and nonporous sidewall component. The hollow vessel contains a candle (60) and candle wick (40). A wicking extension (70) extends from the porous sidewall component, set in from the reservoir base (80) via a recess (100). Because this embodiment includes only one wicking extension, a slanted surface (270) is provided to direct the reservoir liquid composition (140) to the wicking extension.
FIG. 13 depicts an exploded crosscut view of a unit in which a gel composition (150) is filled into the confines of a secondary container (270), each of which being contained in the hollow vessel (10). The secondary container (270) is fabricated from a non-porous composition such as a thermoplastic, or other materials that would also prove suitable. Once the secondary container (270) is filled with a suitable air freshening medium of choice it can then be inserted into the hollow vessel (10).
A flange (280) surrounds the open circumference of the secondary container (270) such that when the secondary container (270) is loaded into the hollow vessel (10), the flange (280) will be supported by the uppermost open edge at the top of the hollow vessel (10).
Although shown in exploded view, a reservoir insert or cartridge (160) is provided and ultimately affixed to the bottom of the hollow vessel. The reservoir cartridge is provided with a narrow opening (190) with a ruptureable foil seal (180), positioned for engagement with a piercing lance (210), which is provided along the bottom of the reservoir base (80). Upon removing the tear away band (220), the recess (100) will rest on the reservoir base upper lip (90), and the foil seal will be torn, thereby emptying the reservoir liquid composition (140) into the reservoir. A convex surface (110) is provided along the bottom of the reservoir to direct the reservoir liquid composition to the recessed channel (130). The bottom of the wicking extensions (70) will ultimately be disposed in the recessed channel.
The secondary container (270) can be used to contain a gel composition or a candle but could also be used to contain other independent fragrance mediums, such as, but not limited to, potpourri, liquid wicks, fragrance membranes and fragranced polymer beads.
FIG. 14 depicts a crosscut view of the unit fully engaged and activated. An insertable reservoir (160) is loaded with a fragrance composition (140) and lockably attached to the base of the hollow vessel (10).
The tear-away band (FIG. 13, 220) has been removed to allow the base to travel upward and in the process have the piercing lance (210) rupture the foil seal (180) over the narrow opening (190) of the fragrance insert (160). The reservoir fluid (140) will drain into the base (80) and consequently contact the wicking extensions (70). The hollow vessel is provided with a recess (100), which joins the reservoir base upper lip (90) such that the porous vessel sidewall and reservoir sidewall form a substantially continuous plane.
A flange (280) is also provided along the outer opening of the hollow vessel. A secondary container (270) is also provided to contain the gel composition (150), both of which are contained in the hollow vessel.
FIG. 15 provides a depiction of a device according to one embodiment of the present application. An exploded view of the device (16,000) is provided in FIG. 16. A glazed coating (10) is provided along the interior of the hollow vessel. A glaze coating (20) is also provided along a portion of the exterior of the hollow vessel. Glaze is further provided along the reservoir rim (40) and the inner reservoir surface (30).
FIG. 17 provides a device (17,000) according to an alternative embodiment of the present application in which three wicking extensions or protrusions (50) are provided. In this embodiment, a wax candle (30), provided with a candle wick (80), is included as the first fragrance medium. The candle is contained in a hollow vessel (10). A recessed groove (90) is provided which ultimately engages with the reservoir rim (100). The reservoir (20) contains a liquid fragrance composition (40). The bottom of the reservoir as a convexed surface (60) so as to direct the liquid fragrance composition to a channel (70), which is formed along the outer periphery of the bottom of the reservoir.
FIGS. 18 and 19 provide an assembled view of an embodiment in which three wicking extensions or protrusions are provided.
In another embodiment of the disclosed subject matter, the volatile medium delivery device can include at least three members: a reservoir containing a volatile medium, a cradle including an exposed emanating surface and a wicking extension and being adapted to engage the reservoir, and an article adapted to engage the cradle. Exemplary embodiments of such a configuration are shown in FIGS. 20-31 and described in greater detail below.
FIG. 20 provides a view of a three-piece volatile medium delivery device (20,000) according to one embodiment of the present application, in which the wicking protrusions or wicking extensions (25) are provided as a separate member (20) (i.e., the cradle). The hollow vessel (10) contains a wax candle (40) and is designed to fit with both the separate member (20) containing the wicking extensions, and the liquid reservoir (30), which contains a liquid fragrance composition (50). As combined, sidewalls of the hollow vessel (10), separate member (20) and reservoir (30) form a substantially continuous plane.
FIG. 21 provides two alternative embodiments (21,000, 21,500) of the device of the present application. The hollow vessel (10) may be constructed of a liquid impervious material with absorbent sheathing (20). In this case the absorbent sheathing or members (30) could partially (as in 21,500) or entirely (as in 21,000) encompass the outside surface of the vessel and serve as means to absorb the liquid fragrance composition contained within the reservoir. With such a design, the hollow vessel 10 is constructed from an impervious material sheathed in an absorbent material to absorb the volatile liquid mixture 50 from the wicking protrusions 20 which are immersed in the liquid mixture contained in the liquid reservoir base. This exposure will allow the volatile liquid to evaporate and emanate from the exposed surface of the porous sheathing.
The three piece design of the device depicted in FIGS. 20 and 21 can also posses the advantage of being more cost effective, as it could simplify the manufacturing process, thus lowering the cost to produce.
A further variant to the examples detailed in FIGS. 20 and 21, the device can also be configured whereby the candle vessel and the wicking protrusions are both entirely constructed of a liquid impervious material. Such a device would be equipped with an absorbent sheathing or members that partially or wholly encompass the outside of the hollow vessel and wicking protrusions. With such a design, the hollow vessel is sheathed in an absorbent material to absorb the volatile liquid mixture from the wicking protrusions, which are also sheathed in an absorbent material to absorb the liquid mixture contained in the liquid reservoir base. This exposure will allow the volatile liquid to evaporate and emanate from the exposed surface of the porous sheathing. The porous material may include, for example, porous plastics and fibrous materials, such as cellulose and polyesters.
With reference to FIG. 22, a further embodiment of the three-piece volatile medium delivery device 2200 for evaporation of a volatile medium into the surrounding environment is shown. In accordance with the disclosed subject matter, the delivery device 2200 can include an article 2202, a cradle 2204, and a reservoir 2206. When the device is assembled, the cradle 2204 can be situated over and partially immersed in the reservoir 2206, which can contain a volatile medium
FIG. 23 illustrates an exemplary embodiment of the assembled delivery device 2300. As shown, the cradle 2304 can be adapted to engage with the reservoir 2306 and the article 2302. For example, the sidewalls of the article, the cradle, and the reservoir can form a continuous plane, providing a seamless visual execution.
The cradle can include three main portions: a reservoir-engaging portion, an article-engaging portion, and an exposed emanating surface.
With reference to FIG. 22, the reservoir-engaging portion can include at least one wicking extension 2208. The number of wicking extensions can be varied to suit the needs of a particular application. For example, FIG. 28 shows an embodiment with three wicking extensions, while FIG. 30 illustrates an embodiment with four wicking extensions. However, the wicking extensions can be designed in a number of forms without departing from the scope of the disclosed subject matter. For example, the wicking extensions 2208 can be connected. The wicking extensions 2208 can project downward and, when the delivery device is assembled, can be fully enclosed within, and rest in intimate contact with the bottom of, the reservoir 2206. Additionally, the wicking extensions 2208 can be designed in a way that minimizes the size (e.g., the mass or the area) of the wicking extensions. Such a design can be used to direct the majority volatile medium in the reservoir towards the emanating portion 2214 by retaining only a minimum amount of volatile medium in the wicking extensions. A lower mass of the porous material of the wicking extension corresponds to a lower amount of the volatile medium lost within the interstitial composition of the porous material. The wicking extensions can be shaped, for example, by removing portions of the porous material used to form the cradle.
With reference to FIG. 23, the reservoir-engaging portion can also include a recess 2310 connecting the wicking extensions 2308 to the emanating surface 2314 The recess 2310 allows the cradle 2304 to engage with the reservoir 2306 and can provide additional stability and improved aesthetics. However, other engaging members can be used in connection with device without departing from the scope of the disclosed subject matter.
With further reference to FIG. 22, the article-engaging portion of the cradle 2204 can include a cradling portion 2212 that engages with the article 2202. The cradling portion can be, for example, the top of a sidewall. Other engaging members can be used in connection with the device without departing from the scope of the disclosed subject matter. The article 2202 can include a complementary engaging portion. For example, the complementary engaging portion can be a recess 2224.
The third portion can include an exposed emanating surface 2214. With reference to FIG. 23, the exposed emanating surface 2314 can be the only portion of the cradle 2304 that is exposed when the device 2300 is assembled. The cradle can be formed from a porous material. Through a process of capillary action, the volatile medium can wickably transfer from the reservoir into the wicking extensions, and then migrate to the exposed emanating surface 2314 for eventual evaporation into the air. In another embodiment, the cradle can be formed from a liquid impervious material and an absorbent sheathing. Suitable materials for construction of the cradle include, but are not limited to, ceramic, porcelain, terracotta, cement, wood, porous polymer (e.g., polyethylene), felted fibers, rigid non-woven, or plaster of Paris.
The cradle 2204 illustrated in FIG. 22 is merely an exemplary embodiment. A cradle in accordance with the disclosed subject matter can be designed in any manner suiting the needs of a particular application. With reference to FIG. 20, another exemplary embodiment of a cradle 20 is shown. Yet another exemplary embodiment of a cradle in accordance with the disclosed subject matter is illustrated in FIG. 13. As shown, the cradle 30 can engage with the reservoir 80 and the secondary container 270 to form a volatile medium delivery device. A person having ordinary skill in the art will understand that further variations to the cradle can be made without departing from the scope of the claimed subject matter.
With further reference to FIG. 22, the reservoir 2206 is adapted to engage the cradle. The reservoir can also contain a volatile medium. The term “volatile medium,” as used herein, includes volatile liquids, gels, and other volatile compositions. Any volatile medium can be used in connection with the disclosed subject matter, including fragrance mediums, essential oils, medicants, insect control agents, and malodor counteractants. The volatile medium can be, for example, a volatile gel composition. In one embodiment, the article can include a candle that melts the volatile gel composition into liquid form. The reservoir can be formed from a material that is impervious to the effects of contact with the volatile medium. Suitable materials include, but are not limited to, thermoplastics such as polyethylene, polyethylene terephthalate, modified acrylonitrile-methyl acrylate copolymer, and acrylonitrile-butadenestyrene, as well as metal and glass. The reservoir can also be formed of a material including a liquid-impervious liner. For example, the reservoir can be formed from ceramic glazed with a liquid-impervious coating, or wood with a thermoplastic or glass liner.
FIG. 24 illustrates an exemplary embodiment of the assembled delivery device 2400. The reservoir 2406 can include a convex base 2416 and a channel 2418 running along the outside of the base. The convex base 2416 can include a center portion of an interior surface of the base that is formed into a convex shape so as to direct the volatile medium 2422 toward the channel 2418. Thus, when a volatile medium 2422 is present in the reservoir, the convex base 2416 can cause the volatile medium to flow into the channel 2418. The ends of wicking extensions 2408 can be disposed in the channel. As such, the design of the reservoir 2418 can direct the volatile medium into the wicking extensions 2408 for later evaporation through the exposed emanating surface 2414. The emanating surface 2414 is exposed to the ambient air and allows the volatile medium to evaporate over a sustained period of time. However, other configurations can also be used to cause the volatile medium to flow toward the wicking extensions. Such configurations can include, for example, the configuration shown in FIG. 12.
In an exemplary embodiment, the volatile medium can be provided in a pre-measured vial 2420. The volatile medium can be loaded into the reservoir 2406. The cradle 2404 can then be placed on top of the reservoir 2406 such that these components engage each other. The article 2402 can then be placed upon the cradle 2404 to complete assembly of the delivery device 2400. The volatile medium 2422 will be wickably transferred into the wicking extensions 2408 and migrate to the emanating surface 2414 for diffusion into the ambient air.
In another exemplary embodiment, the reservoir can be re-filled using reservoir cartridges. FIG. 25A illustrates an exemplary embodiment of the reservoir cartridge. The reservoir cartridge 2500 contains a volatile medium 2502. The volatile medium 2502 can be completely enclosed by the cartridge body 2504, a top seal 2506, and a bottom seal 2508.
FIG. 25B shows an exemplary reservoir cartridge 2500 before the volatile medium is loaded. The cartridge body 2504 can include a large opening 2510 at the top of the cartridge body 2504 and a narrow opening 2512 at the bottom of the cartridge body 2504. The narrow opening 2512 is first sealed using the bottom seal 2508. The bottom seal can be constructed from a heat-sealable material that is capable of being ruptured. The volatile medium can then be loaded into the cartridge body 2502 through the large opening 2510, as shown in FIG. 25C. The large opening 2510 can then be sealed using the top seal 2506. The top seal 2506 can be constructed from a heat-sealable material. Although the narrow opening 2512 and the large opening 2510 of FIG. 25 are described with reference to their sizes, these openings can be of varying size without departing from the scope of the claimed subject matter. For example, the large opening 2510 and the narrow opening 2512 can be the same size.
FIG. 26 illustrates an exemplary embodiment of the delivery device 2600 when a reservoir cartridge 2602 is being loaded into the delivery device. As shown in FIG. 26, the article 2604 can be removed, but the cradle 2606 can remain in place, when accessing the interior of reservoir 2608. In another embodiment, the cradle 2606 must also be removed to access the interior of reservoir 2608. The reservoir cartridge 2602 can then be loaded into the reservoir 2608. The reservoir cartridge 2602 can be, for example, adhesively or mechanically inserted into the reservoir 2608. The reservoir cartridge can be oriented such that the narrow opening of the reservoir cartridge 2602 is directed toward the base of the reservoir 2608. The reservoir 2608 can include a piercing lance 2610 designed to rupture the bottom seal 2614 of the reservoir cartridge 2602. The piercing lance 2610 can be placed at the top of a domed convex center of the base of the reservoir 2608. The piercing lance 2610 can be formed, for example, during an injection molding process used to manufacture the reservoir 2608. The bottom seal can be constructed from any rupturable material including, for example, foil. The article 2604 can then be replaced to form the assembled delivery device.
An exemplary embodiment of the assembled delivery device containing a reservoir cartridge is shown in FIG. 27. When the bottom seal 2722 of the reservoir cartridge 2702 is ruptured, the volatile medium 2720 flows into the reservoir 2708. The volatile medium is then directed by the convex surface 2712 of the reservoir 2708 into the channel 2714, where it can be absorbed by wicking extensions 2716 and released into the air through an emanating surface 2718.
In a further embodiment of the disclosed subject matter, two cartridges can be used so that a second cartridge can be opened once the contents of the first cartridge have been depleted.
With further reference to FIG. 22, the delivery device 2200 can include an article 2202. The article 2202 can be adapted to engage with the cradle 2204. The article can include, for example, a recess 2216 to allow the article 2202 to provide a flush union of the article 2202 with the cradle 2204, as shown in FIG. 22.
For purposes of explanation and not limitation, the article can be a decorative article, a functional article, or a substance-containing article. It should be noted that these terms are not mutually-exclusive; for example, a substance-containing article can also be classified as a functional article because it serves a functional purpose, i.e., it holds the substance. The article can be, for example, a vessel such as a container. The delivery device 2200 contrasts with the singularly positioned devices that are currently available by allowing for the volatile medium diffuser to be used in conjunction with an article such as a decorative article, a functional article, or a substance-containing article, so as to broaden the appeal of the device. The article can be constructed from a wide range of materials depending on the needs of a particular application.
FIG. 28 illustrates an exemplary embodiment of the disclosed subject matter including a substance-containing article, a cradle 2806, and a reservoir 2808. The substance-containing article can include the article 2802 and the substance 2804. The substance can include a fragrance medium such as a gel composition, a candle, potpourri, a reed diffusers, a liquid wick, polymer beads, saturated paper, aerosol, and the like. The use of the delivery device in combination with an additional fragrance medium can service to augment the fragrance awareness created by the volatile medium of the reservoir. However, the substance can also include a wide variety of other substances, including non-fragrant substances. When used with articles that are unfragranced, the delivery device can serve as the primary source of fragrance emanation and create a unique indoor odor experience.
FIG. 29 illustrates another exemplary embodiment of the disclosed subject matter including a substance-containing article, a cradle 2908, and a reservoir 2910. The substance-containing article includes the article 2902, the substance 2904, and a lid 2906. The lid 2906 seals the substance 2904 in the article 2902. The substance can be a fragrant substance, such as bath salts, bath oils, creams, or lotions, or a non-fragrant substance, such as decorative sand or glass beads.
FIG. 30 illustrates an exemplary embodiment of the disclosed subject matter including a functional article, a cradle 3004, and a reservoir 3006. The functional article 3002 shown in FIG. 30 is an ashtray. Other functional articles that can be used with the disclosed subject matter include soap dishes, liquid soap dispensers and the like.
The term “functional article” also encompasses a container, i.e., an article designed to hold objects. FIG. 31 illustrates an exemplary embodiment of the disclosed subject matter including a container 3102.
With further reference to FIG. 22, the disclosed subject matter can also include a decorative article, such as a vase 2202. However, the term “decorative article” can encompass a wide variety of articles, including statues, decorative lids, or the like.
As shown in FIG. 31, the cradle 3104 can be designed to suit the needs of a particular application, and does not have to completely separate the article 3102 from the reservoir 3016. For example, only a segment of the cradle can extend upward to form the emanating surface 3108.
It will be noted that the volatile medium delivery devices shown in FIGS. 22-24 and 26-31 constitute dual-functioning delivery devices. As used herein, the term “dual-functioning” device refers to a device that fulfills two functions. For example, each of the devices in FIGS. 22-24 and 26-31 are designed to emanate a volatile medium. By way of explanation and not limitation, in FIG. 22, the vase 2202 also fulfills at least a decorative or aesthetic function. In FIG. 28, the article 2802 also fulfills a carrying function (i.e., it holds the substance 2804) and, when filled with a fragrant substance, can also fulfill a fragrance-diffusing function. In FIG. 30, the ashtray 3002 fulfills a functional purpose (i.e., it provides a receptacle for the disposal of ash).
In one embodiment, the operation of the present application is multifunctional by design in that it combines, for example, a candle or fragranced gel delivery device with a porous vessel to wick and simultaneously emanate a volatile liquid fragrance composition. Hence, continuous delivery of a fragrance or volatile liquid mixture is achieved, regardless of candle operation. Functions of a candle design include illumination and fragrance delivery form the wax. A secondary function of the burning candle warmth would be to assist in the volatilization of the liquid components residing in the porous walls of the candle vessel. This improved delivery of volatile materials would be most evident with the higher molecular weight or higher boiling components of the reservoir base fragrance. In addition, the multifunctional design encompassing a candle with a liquid wicking feature in a single device would permit creative delivery of volatiles possessing unique characteristics unto themselves and in combination. Applications of this device include, but are not limited to, air-care, malodor elimination, aromatherapy, medicates, and any other composition containing volatile components.
The benefit of having fragrance emanation from both the porous sidewalls of the vessel as well as from the gel composition contained within it results in a highly impactful fragrance dispensing device. Accordingly, embodiments of the present application also provide a method of delivering a fragrance that includes loading the device with a liquid fragrance composition and allowing the fragrance to emanate to the ambient space surrounding the device.
The fragrance compositions that may be used include commercially available fragrances. Fragrances available from Takasago International Corporation are particularly preferred.
Also, malodor control compositions may be used in the liquid-evaporate delivery device of the present application, either alone or in combination with a fragrance composition. Accordingly, the liquid-evaporate delivery device may be used to neutralize and/or control odors, instead of, or in addition to, providing a hedonically pleasing odor to the surrounding air space. Use of malodor control compositions may find utility in bathroom and kitchen applications, and other areas in which malodors are likely to be present.
The liquid-evaporate delivery device may also deliver insecticides or insect repellents. Insect repellents and insecticides known to those of ordinary skill in the art can be used. Preferred insect repellent compositions include insect repellent compositions containing para-menthane diol, commercially available from Takasago International Corporation U.S.A. (Rockleigh, N.J.).
Gels could also be used in the liquid-evaporate delivery device of the present application. The gels could be, for example, fragrance gels or therapeutic gel (e.g. aloe vera gel, essential oil gels).
The device of the present application may be applied to household rooms and used as an air freshener. Alternatively, the liquid-evaporate delivery device may be used in an office environment (e.g. at reception areas), or a place of business (e.g. a reception area) or a place of recreation (e.g. a casino).
