Method and system for improved scent delivery

The present invention<u style="single">, Incense</u>Distribution kit<u style="single">To</u>Related. The present invention provides the user with a scent experience that is less attenuated over time. The present invention thus provides the user with a scent experience that can be more easily noticed over a longer period of time.

It is generally known to use electrical devices to evaporate fragrances and / or fragrance compositions into spaces, especially home spaces, such as the living room, to provide a pleasant fragrance. For example, AIRWICK® Diffuser ACTIF® (manufactured by Reckitt Benckiser) or AMBI-PUR® air freshener diffuser. A variety of such devices are on the market, including (manufactured by Sara Lee). Generally, these devices consist of a perfume or air freshener source, an electric heater, and a power supply. By applying heat to the fragrance or fragrance source, the fragrance or fragrance is continuously supplied to the space in which the device is placed.

The problem with this arrangement is that the person occupying the space quickly becomes accustomed to the fragrance or fragrance, and after a while, does not perceive the intensity of the fragrance as much as the actual intensity, and may not notice it at all. That is. This is a well-known phenomenon called habituation. A solution to this problem has been sought.

One approach to address this issue is described in Patent Document 1 (Whitby et al.). A patent application by Whitby et al. Has been made to provide two or more fragrance compositions in a space, at least one of these fragrance compositions being provided cyclically, methods and The device is disclosed. This method and apparatus may provide a continuous supply of the first fragrance composition and a periodic supply of the second fragrance composition. This air freshener composition (s) may be volatilized by heat and may include a deodorant and / or an insecticide compound. These fragrance compositions are preferably selected such that the two fragrance compositions are contrasting with each other or have different notes. This air freshener composition is generally rhythmically delivered from a device equipped with a heater. The periodic supply of heat to release the fragrance composition is controlled by providing this device, in particular a heater with a control device. This control device is in the form of an electric circuit. The controller is adapted to allow the heater to operate for a short period of time, preferably 15 seconds to 15 minutes, "with an appropriate interval of time between them."

<p num="0006"> However, Whitby et al.'S patent application maintains or sustains the olfactory effects of continuously released air freshener compositions, rather than giving the user a noticeable change in air freshener. It is clear that it is primarily oriented towards that. In addition, Whitby et al.'S patent application refers to the periodic supply of two or more air fresheners, but the user is individual rather than a single air freshener that is a blend of the two compositions. No specific teaching is given regarding release patterns or programs that direct the supply of different air fresheners in relation to each other so that they can actually experience the air fresheners of.</p>

<p num="0007"> (Features and advantages of the invention) We have found that the decrease in user perception of scent is not solely due to well-reported habituation phenomena, but also to physical, mechanical, and / or physical, mechanical, and / or fragrance release devices that occur during use. Or it was discovered that it was also caused by chemical changes. In particular, during use, emissions from the wick were found to be attenuated as a function of time, at least in part due to wick clogging. Clogged wicks reduce volatilization (or evaporation), thus reducing the perception of perfume components. This phenomenon of clogging can be caused, for example, by a chemical reaction in the perfume composition and the gradual but selective evaporation of the non-clogging perfume constituents. The present invention addresses these issues.</p><p num="0008"> In some embodiments, the present invention provides the user with a more noticeable and constant fragrance experience over time when compared to existing products.

The present specification concludes with claims that specify, point out and explicitly claim the invention, but the following description made with the accompanying drawings will help the invention to be better understood. Hereinafter, the present embodiment (typical embodiment) of the present invention will be referred to in detail, and examples of this embodiment are shown in the accompanying drawings. Whenever possible, the same reference number is used throughout the drawing to refer to the same or similar parts.

The present invention relates to methods, devices and systems for releasing volatile compositions as well as novel compositions. In some embodiments, the invention relates to methods and devices for releasing more than one volatile composition. In some embodiments, the present invention relates to releasing one or more volatile compositions. There are numerous embodiments of the methods and devices described herein, all of which are intended to be non-limiting examples.

The method for releasing volatile compositions can include a variety of different embodiments. Volatile compositions can be fragrance compositions, pesticides, air fresheners, deodorants, aromachologies, aromatherapy, compositions that act as pesticides, or the atmosphere can be adjusted, altered, or otherwise filled. It can be any other substance that acts to change the environment. The volatile substances released in a given embodiment of the method can be the same type of substance (eg, two or more fragrance compositions), or they can be different types of substances (eg, fragrance). Agent composition and air freshener). The deodorant or malodor control composition may contain an odor neutralizing substance, an odor blocking substance, an odor masking substance, and a substance selected from a combination thereof. The method is capable of releasing volatile compositions in a procedure in which the release of different volatile compositions automatically alternates between those different volatile compositions.

The composition can include components suitable for use in a volatile composition release device. The constituents are not limited but can be selected based on their kovats Index (KI; as determined by 5% phenyl-methylpolysiloxane as the non-polar silicone stationary phase). The kovats Index places the volatile attributes of an object to be analyzed (eg, constituents of a volatile composition) on a column in relation to the volatile properties of the n-alkane series on that column. .. Typical columns used are DB-5 and DB-1. According to this definition, the KI of normal alkanes is set to 100n (in the formula, n = n-the number of C atoms in the alkane). Next, the number of carbon atoms is "n" and "N", and the corrected retention time t'_nAnd t'_NThe KI of the analyte x that elutes at time t'between two n-alkanes, each with, is calculated as:

<maths num="1"><img id="000002" he="15" wi="158" file="JP5214531B2_D0001.tif" img-format="tif" img-content="drawing" /></maths> On non-polar to slightly polar GC stationary phases, the KI of the workpiece correlates with their relative volatility. For example, an analyte with a small KI tends to be more volatile than one with a large KI. Ranking the objects to be analyzed by their corresponding KI values gives a good comparison of the evaporation rates of the objects to be analyzed in the liquid-gas partitioning system. Volatile compositions according to the invention are about 1800, 1750, 1700, 1650, 1600, 1550, 1500, 1450, 1400, 1350, 1300, 1250, 1200, 1150, 1100, 1050, 1000 or less, or less. Can have KI. The composition comprises the components having the defined KI at about 70% by weight, 80% by weight, 90% by weight, 91% by weight, 92% by weight, 93% by weight, 94% by weight, 95% by weight, 96% by weight. It can be included in% by weight, 97% by weight, 98% by weight, 99% by weight or more, or even higher.

The release of the volatile composition can be controlled and optimized by adjusting the core temperature. The evaporation rate is related to the core temperature. This is described using the gas-liquid partition coefficient as defined below:

<maths num="2"><img id="000003" he="16" wi="158" file="JP5214531B2_D0001.tif" img-format="tif" img-content="drawing" /></maths> In the formula, C_liIs the liquidus concentration of the object i to be analyzed, and C_giIs the gas phase concentration of the object i to be analyzed.

Thus, the invention is intended to alternate between "on" and "off" release of the volatile composition, or to toggle the toggle switch.

The duration of release can range from as short as about 15 minutes to as long as about 48 hours. Intermediate periods are 20, 25, 30, 35, 40, 45, 50, 55, and 60 minutes, and 2, 3, 4, 5, 6, 12, 18, and 24 hours, And can be any other intermediate time. Of course, the release period can range from any listed time to any listed time, eg, 20 minutes to 24 hours, or 30 minutes to 1 hour. One particular example of the release period is 30 minutes. Another example is 45 minutes.

The duration of the reduced release can be changed as well. It can range from as short as about 15 minutes to as long as about 48 hours. Intermediate periods of reduced release are 20, 25, 30, 35, 40, 45, 50, 55, and 60 minutes, and 2, 3, 4, 5, 6, 12, 18, and. It can be 24 hours, as well as any other intermediate time. Of course, the period of reduced release can also range from any enumerated time to any enumerated time, for example 20 minutes to 24 hours, or 30 minutes to 1 hour. .. Reduced release period One particular case is 30 minutes. Another example is 45 minutes.

Reduced release can be characterized by some reduction in release. The reduction in release can be measured quantitatively, for example by a reduction in the weight (mg) of the volatile composition delivered to the surrounding environment per unit time, or, for example, by the perception of the user. It can be measured qualitatively. The reduction can be small or large, resulting in minimal or no release. That is, the emission can be reduced to its ambient level, that is, the level of emission that occurs in the absence of deliberately applied external energy (eg, electricity in the form of heat) applied to the system, indoors. Normal ambient temperatures for the environment range from about 65 ° F to about 75 ° F (about 18 ° C to about 24 ° C).

The present invention contemplates the ability to release more than one volatile composition. The two or more compositions can be the same or different. Different compositions may exhibit the same or different fragrances, or the same or different properties, such as fragrance and malodor suppression.

Release of the two or more volatile compositions can be made such that the two or more compositions are released at the same time or at different times. Thus, in some embodiments, the release of two or more compositions can be entirely overlapping. On the one hand, the emissions can also be designed so that they do not overlap at all. Releases can also be designed to have very few overlaps at release time to very long overlaps at release time. For example, the overlap of release times can range from as short as 0.1 seconds to as long as 48 hours. Release is such that when one composition is released, the second composition is not released, and when the second composition is released, the first composition is not released. Can be designed. Thus, the present invention is intended to alternate or toggle the release of two or more compositions in sequence.

As mentioned above, the release of the volatile composition can occur from a short period of, for example, as much as 15 minutes to a long period of, for example, as much as 48 hours. Release can be any time in between, and in some embodiments the release of the volatile composition is 30 minutes. In other embodiments, the release of the volatile composition is 45 minutes. If more than one composition is released, the first composition may be delivered for 30 minutes (on) and the second composition may not be delivered during that time (off). For the following 30 minutes, the first composition is off and the second composition is on. Of course, it can be tilted towards on and / or off so that there is some overlap in the release of the composition between the tilted phases.

Needless to say, the two or more volatile compositions can be released in any suitable order. The order of release of the volatile composition can be in a pattern or can be random. As used herein, the term "pattern" refers to an order of repetition. In embodiments where the order of release of the different volatile compositions is repeatable, the pattern can be repeated once or as many times as after the first order. As used herein, the term "random" refers to an order in which the release order of volatile compositions is not repeated in a regular manner. It is also possible that the release procedure includes some time in which the order is patterned and some time in which the order is random.

In some embodiments, the two or more volatile compositions are released in an alternating order. For example, a first volatile composition and a second volatile composition can be present and the first volatile composition is released in alternating periods with respect to the second volatile composition. That is, if the first volatile composition is represented by "1" and the second volatile composition is represented by "2", these volatile compositions are 1, 2, 1, 2, ... -Can be emitted in alternating patterns such as. Figure 1 graphically illustrates these release programs. In FIG. 1, this diagram represents the duration of exposure (or activation) of these volatile compositions to an energy source (eg, the heat by which they heat the composition). If in a device that has a vessel, the diagram can represent the period during which the heater is turned on and off). If three volatile compositions are present, they are released in an alternating pattern such as 1, 2, 3, 1, 2, 3, ..., as shown in FIG. obtain.

In looking at these figures (and their accompanying diagrams), it should be understood that they are non-limiting embodiments. Other embodiments do not require a separate volatile source (such as a heater) for each volatile composition. There can be any suitable number of volatile sources for the volatile composition. For example, a single volatile source can be used to volatilize more than one volatile composition. Such volatile sources can be moved, for example, to volatilize different volatile compositions, or (open or close doors or gates between the volatile source and a given volatile composition). It may be possible to selectively induce energy (eg, heat) into different volatile compositions (eg, by doing so). Alternatively, the storage tank can be movable with respect to the volatile source (eg, so that the storage tank can be selectively moved over the heater).

As used herein, the term "interval" refers to the shortest period of time in the release procedure. As used herein, the term "individual release period" can refer to an individual period during which a given volatile material (or combination of volatile substances) is released in a release order. This can generally correspond to, for example, the period during which the heater is turned on for a given volatile or combination of volatiles (although only between the operation of the heater and the release of the volatiles). There may be a time lag). Individual release periods can also refer herein to a first period, a second period, etc., each of which has a start and an end. As used herein, the term "injection" refers to a volatile composition after the heat core has been maintained at a reduced temperature to allow regurgitation of at least one component of the volatile composition. Refers to the early and peak release of. It should be understood that different volatile compositions do not need to be released over an equal period of time. For example, after one volatile composition has been released, different volatile compositions can be released for a shorter or longer period of time. In another example, one volatile composition can be released followed by another interval of the same volatile composition before different volatile compositions are released. If different volatile compositions are not released for the same period, it may be desirable to have a larger amount of composition with a longer cumulative release time so that the volatile compositions are emptied at about the same time. is there. There are many possible alternating release sequences. For the three volatile compositions, some other non-limiting examples of possible release patterns are (1, 2 2, 1, 3 3); (1, 2, 3, 3, 2, 1). ; And (1, 2 2 2 2, 1 1, 3 3 3 3, 1), but are not limited to these.

In some embodiments of the method, the volatile composition can be released for individual release periods of about 15 minutes or less, but in some cases it is more desirable for each release period to be longer than 15 minutes. is there. In the case of fragrant substances, longer periods may be more desirable. In one embodiment of the method, the volatile compositions alternate for individual periods of greater than 15 minutes and less than about 12 hours, or less than about 24 hours, or less than about 48 hours, or longer, respectively. Is released to. All numerical ranges described throughout this specification include all narrower numerical ranges within the wider numerical range as expressly set forth herein. Thus, in another non-limiting embodiment, the volatile composition is released alternately for a period of time greater than 15 minutes or greater than or equal to about 1 hour and less than 2 hours. In one embodiment, each volatile composition is released for a period of about 72 minutes. In one embodiment, each volatile composition is released for about 30 minutes.

The volatile composition may be released such that one follows immediately after the end of the release period of the other. In other embodiments, the volatile compositions are released with an interval between the end of the release period of one of them and the beginning of the release period of another volatile composition. Can be done. FIG. 3 is a diagram showing one non-limiting embodiment of a release program for releasing two volatile compositions, where there is an interval between the releases of the volatile compositions. "G" indicates the interval. In other embodiments, the volatile composition can be released so that there is an overlap during the release period of two or more volatile compositions. FIG. 4 is a diagram showing one non-limiting embodiment of a release program for releasing two volatile compositions, where there is an overlap of release of the volatile compositions. The symbol "&amp;" indicates the release period during which both volatile compositions are released. FIG. 5 shows one non-limiting embodiment of a release program for releasing three (or more) volatile compositions, one volatile composition release and two other volatilizations. There is an overlap with the release of the sex composition. In other embodiments, one or more volatile compositions can be released continuously and another volatile composition can be released for a period of time greater than 15 minutes.

If it is desirable to have an interval between the end of the release time of one of the volatiles and the beginning of the release period of another volatile, the interval can be any suitable duration. The interval period between the releases of volatiles may be longer than 0% and up to 100% of the duration of the previous or subsequent release period, or longer. If it is desirable to have an overlap during the release period of two or more volatiles, the overlap can be of any suitable duration. The release period of the volatile material that is subsequently released may overlap up to 100%, longer than 0% of the time the first volatile material is released. In certain embodiments, it may be desirable, for example, to have about 25% overlap between different volatiles. For example, instead of releasing the scent substance "A" for 60 minutes and then the scent substance "B" for 60 minutes, the scent substance "A" is released for 45 minutes, followed by the scent substances "A" and "B]. Both can be released for 30 minutes, followed by the scented substance "B" for 45 minutes, in which case 30 minutes is the total release time of the scented substances "A" and "B" and their combination ( That is, it is 25% of 120 minutes).

The duration of the interval or overlap can be controlled automatically. In certain embodiments of articles (classes) or devices (classes) used to release volatiles, the articles (classes) or devices (classes) are provided by the user at any interval and / during the release period. Alternatively, a control device may be provided to allow control of the duration of the overlap. Overlapping procedures are used for any purpose, for example, when it is desirable for the user to smell not only individual scented substances for one period, but also scented substances blended for another period. May be good.

In certain embodiments, it is desirable that the method be operated by flame-free (eg, non-candle) articles (classes) and / or devices (classes). In certain embodiments, it may be desirable for the method to operate independently of other media, such as, but not limited to, cinema, television, and the like. .. In other embodiments, it may be desirable to operate the method in a manner coordinated with other media.

There can be any suitable release program or scheme for releasing the volatile composition. In certain embodiments where the scent is released, it is desirable that the device provide an alternating scent experience rather than a lasting impression of a single scent. In one embodiment, a day / night release program is provided in which one fragrance substance is provided to awaken a person and another fragrance substance is provided for a period of time while they are trying to fall asleep. May be desirable. Thus, in some embodiments, it may be desirable to deliver the same fragrance substance at the same time each day. In other embodiments, it may be desirable to avoid a stereotyped scent experience. For example, if it is desirable that the emission patterns do not have simultaneity over 24 hours, but that the user have a different scent experience at a given time between day or night for each 24-hour period. There is also. Many other embodiments are possible.

The total release program (or simply the "release program") refers to the overall sequence of individual release periods from start to finish. In certain embodiments, it is desirable that the release program be continuous. The term "continuous", when used in connection with a release program, means that once the program is started, there is a planned release sequence over the entire period. This release program can include a period of time during which there is an interval in release, as described above. There is not necessarily a continuous release of the volatile composition, but it is still considered a continuous release program. However, it should be understood that the release program can be interrupted (eg, switched off) by the user if desired. That is, the method can provide a user interface, which can provide the user with the ability to interrupt the release program. In certain embodiments, the release program may be designed to operate continuously or nearly continuously until at least one of the volatile compositions is substantially empty. In certain embodiments, it is desirable that the release program be run continuously until all volatile compositions are substantially empty, and this should happen at about the same time. The release program can have any suitable length, including, but not limited to, 30 days, 60 days, or a shorter or longer period, or any period between 30 and 60 days.

One example of a device that can be used in accordance with the present invention is one that comprises a core. When using such a device, the wick acts as a conduit for transporting the volatile composition from the storage tank to the release point. The wick is generally porous or contains pores, which provide the flow of the volatile composition. The wick can be made from a variety of materials including, but not limited to, cellulose fibers, metals, plastics, ceramics, graphite, and fabrics. Synthetic materials such as plastics may be desirable because of their uniform performance. Plastic materials that can be used to form a porous core include high density polyethylene (HDPE), polytetrafluoroethylene (PTFE), ultra high molecular weight polyethylene (UHMW), nylon 6 (N6), polypropylene (PP), and poly. Examples include, but are not limited to, vinylidene fluoride (PVDF) and polyether sulfone (PES).

Cores can be described in relation to their average pore size. The core may have any suitable pore size. U.S. Patent Application 2002/0136886A1, entitled "Porous Wick for Liquid Vaporizers," describes a standard method for measuring pore size. In certain embodiments, the average pore size of the core useful in the present invention ranges from about 10 microns to about 500 microns, or about 50 microns to about 150 microns, or about 60 to about 100, or about 70 microns. Is. The wick can have an average pore volume of about 15% to about 85%, or about 25% to about 50%. Similarly, the wick is determined only by the desired application and can be of varying length. In certain embodiments, the core can be as short as 1 mm, as long as 100 mm, longer, or any length in between. The core can be in the range of about 5 mm to about 75 mm, or about 10 mm to about 50 mm in length.

Optionally, the cap may have a clip structure that facilitates fixing or positioning the volatile composition distributor to the building structure of the house or to parts of furniture or car fixtures. Figure 11 shows a cap structure that defines two vents, and a rotating knob to selectively expose one or another vent, or not expose either vent. Shows a rotatable cover that is manually actuated by. In some embodiments, the cap structure may be activated automatically.

A particularly useful volatile composition distribution module and material for use with equipment having a cap structure.

The device 20 can include many additional arbitrary features. The device can be provided with an instruction device that makes the person more aware that the released volatiles have changed. Such an indicator can be visual and / or auditory. For example, in the case of scented substances, such an indicator may allow a person to know which scented substance is being released at a given time. In the embodiments shown in FIGS. 6-8, the indicator is in the form of lights 70 and 72. In another example, at least part of the device 20 (eg, all or part of the housing) or storage tank may be made of a type of plastic that changes color when heated.

The device may be provided with an additional user control device. The device is equipped with an "on / off" switch, which allows the user to turn the device on and off without removing the device from the electrical socket. The device allows the user to control the release period of one or more volatile compositions and / or the time between the releases of different volatile compositions, or the time during which the volatiles overlap. A control device can be provided to enable this. For example, in one non-limiting embodiment, if the device is equipped with the ability to release each volatile substance for a period of more than 15 minutes and 48 hours or less, the device has one or more users. A control device can be provided that allows the release period for the volatile composition to be set, for example, 30 minutes, 45 minutes, or 72 minutes, or 1 hour.

The device may be provided with an additional user control device. The device can include a temperature controller or other switch to allow the user to adjust the temperature setting of the heat source for one or more volatile compositions. The settings may be pre-defined for a particular volatile composition or may be adjusted based on the selected temperature to be applied to the wick.

The device can also be sold in the form of a kit that includes the device and one or more storage tanks of the volatile composition. This device and / or kit also directs the user about a particular release period that may be used to produce a particular result, and / or place the device anywhere in a given space. It can include instructions on what to do. For example, the instructions may include instructions for setting the device relative to the size of the room, vehicle, etc. in which the device is placed. Such instructions may also include instructions to the user to choose more frequent changes during the release of the scented material in order to recognize the scent more strongly. Instructions may also be provided in connection with other devices to specify how to operate the device. Instructions can be provided in any suitable form, eg, in writing, audio, and / or video.

The device can also be powered by batteries so that it does not need to be plugged into an electrical outlet. The device can also be configured to be connected to a current source and powered, and also powered by batteries, or both. The device can also be provided with an adapter that can be plugged into an automobile cigarette lighter. In addition, the device allows the user to control the nature of any or all of the release of the device, including but not limited to changes in the volatiles being released, without touching the device. A remote control device that enables it can be provided.

The apparatus may include a microprocessor having fewer components than an analog circuit and having improved circuit quality for each lot number. The microprocessor allows the user to program and control temperature characteristics by adjusting to change behavior. If desired, the microprocessor may be connected to the user interface. This can be any suitable type of user interface. Examples of user interface types include, but are not limited to, LCD screens and LEDs. In addition, the microprocessor allows components to connect multiple devices, such as those located in different parts of a room or located in different rooms, to each other. For example, a microprocessor can allow a remote control device to send a digital signal over an infrared beam to "on" or "off" another device.

Many other types of equipment are possible. For example, in other embodiments, the methods described herein can be operated by two or more distributors. Such distributors include all types of distributors, including but not limited to aerosol atomizers. FIG. 12 shows a non-limiting embodiment of the arrangement of aerosol atomizers 80 and 82. The aerosol atomizer used in such a manner can function in any suitable manner. In some embodiments, the aerosol atomizers may operate independently, eg, may be operated by a timer 84 so that they switch the release of volatiles in the desired manner. The distributor can be powered in any suitable manner, such as by battery 86. Distributors 80 and 82 may be placed adjacent to each other, or they may be placed in different parts of the space where it is desired to release their volatiles. FIG. 13 shows another non-limiting embodiment of the distributor 88. In FIG. 13, the disperser 88 is a single device that includes two (or more) dispensers such as the aerosol atomizers 90 and 92. The device 88 may be actuated by one or more timers, or sensors 96, and can be powered by one or more batteries, or other power sources.

In some embodiments, the device can be configured to be turned on and off in response to some stimulus, such as by a sensor that responds to light, noise and / or movement. For example, one of the devices can be configured to be turned on when the light is felt, and another device can be configured to be turned off when the light is felt. In another embodiment, the microprocessor can be used with a motion sensor to operate a device (eg, a heater and / or a fan in the device). For example, the device can be turned off all the time until a person moves near the motion sensor. The device can then be turned on when a person walks near the motion sensor. The use of microprocessors provides flexibility in controlling the characteristics of volatile release characteristics. This is because the microprocessor can be replaced if it wishes to change the emission characteristics. Replacing the microprocessor eliminates the need to modify the entire circuit.

<p num="0101"> Example 1: Perfume evaporation of the plug-in device decreases over time It is known in the art that long-term exposure to fragrances produces a habituation effect, which makes it difficult for a person to recognize the presence of a particular fragrance even at the same concentration. This phenomenon occurs with the use of commercially available fragrance release devices.</p><p num="0102"> However, the Applicants believe that, in addition to the phenomenon of habituation, the decrease in fragrance substance output by a commercially available device over time causes the user to lose recognition of the fragrance. To test this hypothesis, a commercial product grade (GLADE)® Sky Breeze® was plugged in (ie turned on) to release fragrance material over an extended period of time. The rate of evaporation (or rate of release) was determined by measuring the starting content of the device and making daily measurements to determine the amount lost.</p><p num="0103"> Figure 14 shows the results of the study. As can be seen from the figure, the evaporation rate decreases remarkably over time. In fact, the evaporation rate dropped by nearly 50% after only one week of use. In addition, there is a visual difference between continuously used wicks and toggle-controlled wicks. (See Figure 15, this figure shows a photo of a wick that has been used continuously for 21 days, compared to a photo of a wick that has been toggled on and off for 42 days.</p><p num="0104"> Example 2: Clogged core causes a decrease in evaporation rate The observed decrease in evaporation rate was caused by a number of factors, including selective evaporation of the more volatile compounds and clogging of the wick. Further research was carried out to determine the mechanical reasons behind the decrease in evaporation rate.</p><p num="0105"> Grade (GLADE)® Vanilla Breeze® and Hawaiian Breeze® fragrance devices were turned on for 28 consecutive days. At the end of the 28th, the wick was removed from the device and frozen in liquid nitrogen. Samples were taken from the top, middle, and bottom of the wick. At the same time, the volatile composition remaining in the storage tank was sampled. The sampled volatile compositions were analyzed by gas chromatography to determine their kovats Indices. 16 and 17 show the results graphically.</p><p num="0106"> As can be seen from FIG. 16, the wick changes visibly over the test period. The bottom of the wick is the lightest in color and the wick becomes darker towards the top. This is also clear in the picture of Figure 15.</p><p num="0107"> Figure 17 shows exactly what happens when the core is clogged. There was little difference in the contents of the storage tank between the different components, and the low, intermediate, and high volatile components were little different from the controls, and little different from each other. The same was observed for the bottom and middle of the core.</p><p num="0108"> However, the top of the core showed a marked difference. The highly volatile compounds were mostly depleted, and the intermediate volatile compounds were slightly higher than the controls. Most notably, less volatile compounds were collected at the top of the core than in controls by more than 150%. The population of volatile compounds at the top of the wick (the main location of volatilization) was biased towards the extremely low volatile constituents. Thus, these low volatility components effectively suppressed the rate of evaporation, effectively "clogging the core".</p><p num="0109"> Not bound by theory, what is happening is the accumulation of low volatile material at the top of the core, which causes the more volatile material to move to the top of the core and evaporate. It is hindered. At the same time, the compounds in the more volatile volatile composition selectively evaporate, and the less volatile compounds are concentrated at the top of the core, further exacerbating the phenomenon of clogging. Thus, for many reasons, which can be additional or even synergistic, the evaporation of volatiles decreases rapidly during long-term use of the core device. The energy continuously applied to the device in the form of sustained heat to the wick causes these less volatile compounds to move against the concentration gradient, forcing them to accumulate at the top of the wick. .. Releases from commercial plug-in products showed a drop of about 50% during use for only one week. (See Figure 14.) Volatile components by deliberately switching the toggle switch of the heat core device to the "off" state, or by introducing an interval between the emissions of a single or multiple core devices. Diffuses inside the wick and reaches an equilibrium concentration close to the composition of the volatile constituent mixture in the storage tank. Thus, turning the toggle switch "off" or giving spacing during emission by removing heat from the wick normalizes the concentration gradient that "clogs" the wick.</p><p num="0110"> Example 3: Toggle switching reduces clogging and improves evaporation rate When it was discovered that the decrease in evaporation rate was due to clogging of the wick, steps were taken to resolve the problem. Surprisingly, allowing the wick evaporator to rest (generally by weakening the heat applied to the wick) causes backflow of volatiles inside the wick, which is more volatile. It has been discovered that lower constituents can flow with a concentration gradient to return to equilibrium. At the end of the rest period and the regurgitation of the less volatile constituents, the energy is reapplied to the system for a limited period of time, during which time the composition volatilizes again. This cycle can be repeated any number of times.</p><p num="0111"> FIG. 18 shows that the evaporation rate can be significantly improved by turning the single core device on and off with a toggle switch. Simply put, Figure 18 shows two evaporation curves for a commercial product, Grade® Sky Breeze®, which are operated in two different ways. It was. One device was kept continuous for approximately 4 weeks ("no toggle control"). The other device was cycled on and off for an interval of 72 minutes (toggle control) for 8 weeks. (It took twice as long to test the toggle-controlled device, so we divided the value on the "day" axis by 2 to achieve a comparable curve.) As can be seen from FIG. 18, the on / off circulation of the core device results in a significant increase in the rate of evaporation from the device. The picture in Figure 15 provides evidence that on / off circulation significantly reduces core clogging.</p><p num="0112"> Example 4: Larger pore size improves evaporation properties When it was discovered that wick clogging was responsible for reducing evaporation and that reducing clogging could increase evaporation, further to identify ways to improve evaporation. Steps have been taken. This example shows that increasing the pore size increases evaporation.</p><p num="0113"> Simply put, AIR WICK® Country Belize® fragrance device with two cores: a) average pore size of 36 microns, and b) average pore size of 73 microns. Tested. The two wicks were tested by operating the device continuously by turning it on and off with a toggle switch for more than a month. Figure 19 shows the result.</p><p num="0114"> As can be seen, within the first week, cores with large pore dimensions performed significantly better than cores with small pore dimensions. This difference decreased in the second week and disappeared by the third week. This convergence at the point of low performance is considered to be due to the clogging of the core. Core clogging occurs much faster with cores with smaller pore sizes than cores with larger pore sizes. From these experiments, it can be concluded that a core with a large pore size produces better evaporation than a core with a small pore size.</p><p num="0115"> Example 5: Shorter wicks work better Additional research was done to determine if other features of the wick could improve the evaporation properties. This example shows how evaporation can be improved by reducing the length of the wick.</p><p num="0116"> Simply put, AIR WICK® Country Berries® fragrance devices are used with two 73 micron cores, a) 75 mm long, and b) 85 mm long. Tested. The two wicks were tested by running the device continuously for more than a month. The device was alternately turned on and off every 72 minutes. During the "on" part of each cycle, the temperature of the heater was 70 ° C. Figure 20 shows the result.</p><p num="0117"> As can be seen from the figure, the shorter core produced more stable evaporation properties. After longer than 3 weeks of use, evaporation was reduced by only about 25%, while evaporation from long wicks was reduced by more than 50%.</p><p num="0118"> Example 6: Determination of circulation time Additional studies were performed to determine the cycle time to achieve the most desirable fragrance release for the dual core system.</p><p num="0119"> Simply put, two AIR WICK® Country Berries® fragrance devices were tested. The first time was turned on and off alternately every 30 minutes. The second time was turned on and off alternately every 72 minutes. Emissions were measured using a photoionization detector (PID), Photovac 2020. The results were plotted against time. In each case, the recorded results were additionally shifted by 30 minutes and 72 minutes, respectively, to simulate a second identical scent release core. The plots are shown in Figures 21 (a) and 21 (b).</p><p num="0120"> As can be seen, the 30-minute cycle time for the two-core system achieved the most desirable level, the lowest percentage of peaks: valleys for the simulated combination curve. However, it should be noted that longer cycle times can be effective for tricore systems. The theoretical ideal is an immeasurable core. Obviously, from a practical point of view, fewer cores are required, and 2, 3, 4, or 5 cores may be more practical.</p><p num="0121"> Example 7: Determining the effect of cycle time on volatilization Additional studies were conducted to determine the effect of cycle time on volatilization of perfume compositions from a single core system.</p><p num="0122"> Simply put, four AIR WICK® fragrances were used in this study. The wick was made of porous polyethylene with an average pore size of 73 microns and an average pore volume of 38%, with a length of 85 mm and a diameter of 6.8 mm. During the "on" part of each cycle, the temperature of the heater was 70 ° C and an average core temperature of 60 ° C was obtained based on temperature measurements at the top of the core (hot part) (temperature probe core). Placed on top of). The first device was turned on and off alternately every 15 minutes. The second device was turned on and off alternately every 30 minutes. The third device was alternately turned on and off every 45 minutes. The fourth device was alternately turned on and off every 72 minutes. Emissions were measured using a photoionization detector (PID), Photovac 2020. The test site was a 10 x 10 ft (3 x 3 m) room with ambient temperature and ambient airflow.</p><p num="0123"> Release was tested on each core after 2 weeks of use of the device and then 4 weeks of use. The PID sensor was positioned approximately 5 mm above the center of the top of each core. Emissions were sampled at the time of peak emission (the first emission after heat was applied to the wick) and once a minute throughout three full on / off cycles. For example, at 2 weeks for the 3rd device, the release was sampled once a minute for the total sample time of 270 minutes; again at 4 weeks for the 1st device, for the total sample time of 270 minutes. Emissions were sampled once every minute. Electrical readings from the PID were captured and the average concentration of perfume at the top of the core during the measurement period was quantified in parts per million. The results of one of these studies are shown in Table 11.</p><p num="0124"><tables num="11"><img id="000015" he="48" wi="159" file="JP5214531B2_D0001.tif" img-format="tif" img-content="drawing" /></tables> Other embodiments of the invention will be apparent to those skilled in the art by reviewing the specification and operating the inventions disclosed herein.
