DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

The present invention, in some embodiments thereof, relates to a device and method for controlling odor and, more particularly, but not exclusively, to a skin adhesive scent patch.

Overview

An aspect of some embodiments of the current invention relates to a skin patch that can be activated discreetly to give off a fragrance while attached to skin and/or clothing. Optionally, the patch may remain in place for an entire day. For example, the patch may be unobtrusive, comfortable and/or stable for at least 8 hours and/or at least 12 hours and/or at least 24 hours. Optionally, while the patch is worn, a wearer may activate the patch to give off a fragrance and/or control an odor. Optionally, the patch can be activated without scented materials contacting the skin of the user. In some embodiments, activation of the patch will not produce a byproduct (for example, it may not be necessary to remove a cover which would then need to be disposed of). Optionally, once activated the patch continues to spread fragrance and/or control odor for an effective period. Optionally, the effective period may be less than the time that the patch is configured to remain on the skin. For example, the effective period may last up to 15 minutes and/or between 15 minutes to an hour and/or between an hour to 4 hours and/or between 4 hours to 8 hours and/or longer.

An aspect of some embodiments of the current invention relates to a skin patch that includes a volatilization area and/or a reservoir containing fragrance and/or volatile solvent. Optionally, the patch is activated after it is placed on the skin. For example, the patch may be activated by moving the solvent and/or the fragrance to the volatilization area. Optionally the fragrance will be released without contact with the skin of the wearer.

In some embodiments, a user may actively control the patch. For example, the user may transfer the contents of the reservoir to the volatilization area (for example by putting pressure on the reservoir to force its contents to the volatilization area). Alternatively or additionally, the patch may be activated without active involvement of the user. For example, body heat and/or moisture (e.g. sweat) and/or motion of the user may change a characteristic of a substance (for example decrease viscosity) and/or change a characteristic of the patch facilitating the transfer of the contents of the reservoir to the volatilization area. For example, the reservoir may be elastic pushing its contents to the volatilization area. Alternatively or additionally, movement of the wearer of the patch may flex the reservoir and push fluid to the volatilization area. Optionally, a one-way valve will facilitate transfer from the contents of the reservoir to the volatilization area and/or resist transfer from the volatilization area back to the reservoir.

An aspect of some embodiments of the current invention relates to a patch having a mechanism to refresh a fragrance and/or odor control. For example, the patch may have a have multiple reservoirs of fragrance and/or solvent. Optionally, when one reservoir has expired another can be activated. Optionally, the patch is effective without the fragrant chemicals and/or solvent contacting the user.

In some embodiments, the patch may include a volatilization area. Optionally, the volatilization area is configured to increase the rate of volatilization of the effective ingredients. For example, the surface area of the volatilization area may be large. For example, the surface area of the volatilization area may be between 20% to 40% of the exposed surface of the patch and/or between 40 to 80% of the exposed surface of the patch and/or between 80 to 100% of the exposed surface of the patch.

Some embodiments of the current invention may be useful to a person who seeks a discreet way to control odors and/or fragrances in around him. For example, a person may find himself in an area where he wishes to nullify an offensive odor without offending the people around him (for example without offending a person who is the source of the odor). For example, a person may run into a person with whom he wishes to converse at an inopportune moment. Optionally, some embodiments of the current invention may be worn discreetly and/or activated discreetly when needed. In some cases, a scent patch and/or an odor controlling patch may be used where it is difficult to bring a bottle of liquid perfume, for example, on an airplane and when the user is wearing tight clothes and does not want a bottle bulging from his pocket.

In some embodiments, patches may be packaged in various forms. For example, patches may be sold in boxes of separate patches which may optionally be individually wrapped. Alternatively or additionally, patches may be arranged in one or two dimensional array. For example, patches may be arranged on a roll. Optionally a strip of patches may be boxed and/or individually separated.

In some embodiments, a scented patch in accordance with the current invention may be used as a perfume sample and/or as perk to be given out, for example to a purchaser of product such as houseware or clothing or jewelry.

In some embodiments, a patch in accordance with the current invention will be connected to clothing and/or to a pin and/or to a hook and loop connect (e.g. Velcro ®). Detailed Embodiments

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

Referring now to the drawings, FIG. 1 illustrates a multi-reservoir fragrance patch in accordance with an embodiment of the current invention. In some embodiments, a patch may include a volatilization area 100 for exposing an odor affecting substance to air. Optionally, multiple reservoirs 101, 102, 103 are in selective fluid communication with the volatilization area. For example, when it is desired to affect an odor, a flow is opened from a reservoir 101 to the volatilization area. Optionally, fluid from the reservoir 101 flows to the volatilization area and/or contacts the air. For example, a reservoir 101 may contain a scented liquid and/or the reservoir 101 may include volatizing agent (for example, the volatilization area may include a scented substance that is activated by the volatilizing agent). Optionally, the reservoirs 101, 102, 103 and/or the volatilization area are positioned on a flexible substrate 104.

In some embodiments, a surface of the substrate 104 includes an adhesive 105. For example, the adhesive 105 may be configured for holding the substrate 104 to the skin of a wearer. In some embodiments, the substrate 104 may be thin and/or flexible enough to wear on the skin discreetly under clothes.

In some embodiments, a patch may include multiple reservoirs 101, 102, 103. For example, when the patch is not being used, the odor affecting agent is held inactive in a reservoir 101. When it is desired to control an odor, a reservoir 101 is activated. For example, the reservoir 101 may be uncovered and/or the contents of reservoir 101 may be moved from an inactive location (e.g. a closed reservoir) to an active location (for example a contract area with a large surface). Alternatively or additionally, the reservoir may be activated by opening the reservoir to contact air. Optionally, each reservoir 101, 102, 103 includes the same contents. Alternatively, different reservoirs 101, 102, 103 may include different scents and/or solvents and/or concentrations, for example for producing various possible smells and/or mixtures.

In some embodiments, a reservoir 101 may include a hollow portion of a patch (e.g. a bubble) in which a content is stored. Alternatively or additionally, a reservoir 101 may include an absorbent material (e.g. a sponge and/or a fabric).

FIG. 2A illustrates a method of controlling odor around a person in accordance with an embodiment of the current invention. In some embodiments, a user carries an unobtrusive device 200 (e.g. wears a patch) including an odor affecting substance and/or a volatilization area for contacting the substance with air. Optionally, the device is carried in an inactive state. For example, in the inactive state, the device does not produce an obvious smell and/or is not apparent on the user. For example, the device may be worn as a patch under clothing. Optionally, when user wants to neutralize an odor and/or release a scent, the device is activated. Optionally, the activation of the device volatizes the scent in a reservoir. For example, one or more reservoirs contain scent, volatilization material and/or an activator. Optionally the activation of the device causes the mixing of scent with an activator and/or volatilization material. For example, the scent may be mixed with a solvent and/or volatilizer.

In some embodiments, the device may be capable of multiple activations and/or reuse. For example, the device may include multiple reservoirs. Optionally each reservoir is activated separately. Individual activation of different reservoirs optionally facilitates user activating the device when necessary (for example to control an odor) and/or deactivating it for example to remain discreet.

In some embodiments, a device is configured for discrete activation 201. For example, the odor affecting substance may be released gradually. For example, gradual release may allow a person to affect an odor without a sudden change in odor making it obvious that an action was taken. Optionally, activation does not require changing a position of an object and/or moving an object between a covered position and a revealed position. For example, activation may not require removing an object like a patch and/or a perfume bottle from one’s pocket and applying the object. For example, activation may not require removing a disposable object (like an adhesive cover) that then must be disposed of. For example, activation may include moving a substance from one location on the device to another location on the device. For example, activation may be achieved by uncovering an activation substance (for example a fragrance reservoir). For example, activation may be achieved by moving an activation substance (for example a fragrant substance) to a contact area. For example, activation may be achieved by moving an activation substance from a closed reservoir to a volatilization area.

In some embodiments, the device may be activated on demand. For example, a user may squeeze a flexible patch to push a fluid from a flexible reservoir to a volatilization area and/or to break a seal between a reservoir and a volatilization area. Moving the fluid to the volatilization area optionally releases an odor controlling substance to the air. Alternatively or additionally, activation may be passive. For example, when a wearer exerts himself, changes in the temperature, moisture and/or movement may release the activation substance without the user taking any direct action. For example, the activation substance may be automatically released when there is an increase in the temperature of and/or moisture on the skin of a wearer and/or when there is an increase in the movement of a wearer. FIG. 2B illustrates a reservoir 202 containing a scented liquid (for example a perfume and/or a cologne and/or a spirit and/or an extract and/or an aromatic oil and/or a musk) in accordance with an embodiment of the current invention. Optionally, upon activation of the device (e.g. the patch), the scented liquid is selectively released and/or volatilized 203. For example, the scented liquid may be transferred from a closed reservoir to volatilization area exposed to an external atmosphere.

FIG. 2C illustrates a reservoir 204 containing a volatilizing agent (for example a volatile solvent (e.g. alcohol and/or oil and/or a rectified spirit and/or a wax) in accordance with an embodiment of the current invention. Optionally, upon activation of the device the volatizing agent is selectively placed into contact with a scent source 205 (for example a concentrated scent) and/or volatilized 206. For example, a volatilization area may be preloaded with a scent. Optionally the scent may be concentrated and/or stabilized (for example impregnated into a wax and/or a sponge and/or a fabric). Upon activation, the volatile solvent may be transferred from a closed reservoir to the scent causing volatilization of scent. For example, a reservoir may include between 0.05 to 0.1 mΐ and/or between 0.1 to 0.5 mΐ and/or between 0.5 to 5 mΐ and/or between 5 to 50 mΐ.

FIGs. 3 and 4 are schematic exploded and perspective views respectively of a scent patch in accordance with an embodiment of the current invention. It is understood that any, some and/or all of the optional features illustrated with respect to one embodiment (for example the exemplary embodiment of FIGs. 3 and 4) may be included in other embodiments (for example as illustrated in FIGs. 1, 5, 6, 7, 9, 10, 11 and/or 12).

In some embodiments, a patch includes a substrate. For example, the substrate of the patch may include a base 301, 401. For example, the base may include a moisture barrier. For example, the moisture barrier may prevent some or all of the fluids stored within the patch from contacting the surface to which the patch is attached (for example the skin of a wearer of the patch). Alternatively or additionally, the substrate may include a cover and/or top barrier 302, 402. Optionally the cover may include a moisture barrier, for example to prevent wetting the top of the patch. Alternatively or additionally, the cover and/or the base may retain fluid and/or a fragrance from escaping the patch while the patch is not activated. In some embodiments, functional areas may be delimited on a substrate. For example, a volatilization area and/or a volatilization face 306, 406 for contacting a fluid with an external atmosphere may be delimited. Optionally, the volatilization area may include a volatilization pad 303. For example, the volatilization pad 303 may include a material that absorbs a volatile liquid and/or exposes the liquid to the air for volatilization. Optionally the cover of the patch includes a deployment opening 304, 404 exposing the volatilization area to an external atmosphere. Optionally the deployment opening 304, 404 may have a peel off cover or activation tab or tabs 305, 405, for example to protect the volatilization area from drying during storage. In some embodiments, each of the multiple reservoirs (for example 4) 307, 308, 309, 310, 407, 408, 409, 410 may be delimited for storing one or more fluids. Optionally, the reservoirs are located on one side of the patch, i.e., on a reservoir side 321, 421. Optionally, for each reservoir, a valve 311, 312, 313, 314, 411, 412, 413, 414 may control fluid communication between the reservoir 307, 308, 309, 310, 407, 408, 409, 410 and the volatilization area 303. In some embodiments, areas for function units of a patch may be delimited to different areas on the surface of a substrate (for example, as illustrated in FIGs. 2, 3, 9 and 12). Alternatively or additionally, the space for different functional areas of a patch may be delimited in layers of the patch (for example as illustrated in FIGs. 10 and 11).

In some embodiments, a barrier may delimit functional units on a patch. For example, a barrier strip 315, 415 may divide between a reservoir 307, 308, 309, 310, 407, 408, 409, 410 and a volatilization area 303. For example, the barrier may form a wall sealed on the top 302, 402 to the cover and the bottom by the base 301, 401 blocking fluid communication between the reservoir 307, 308, 309, 310, 407, 408, 409, 410 and the volatilization area 303. Optionally the barrier may be made of an impermeable and/or flexible material, for example silicone. In some embodiments, a valve 311, 312, 313, 314, 411, 412, 413, 414 may facilitate controlled fluid communication across the barrier (e.g. between a reservoir and the volatilization area). For example, a valve 311, 312, 313, 314, 411, 412, 413, 414 may be formed by cutting a slit in the flexible barrier. Under normal conditions, elasticity of the silicone closes the valve 311, 312, 313, 314, 411, 412, 413, 414 and prevents fluid flow from the reservoir 307, 308, 309, 310, 407, 408, 409, 410 to the volatilization area 303. Optionally, where there is a large pressure differential between the reservoir and the volatilization area, the pressure drives fluid across the valve. For example, a user may squeeze the patch at a location of reservoir 307, 308, 309, 310, 407, 408, 409, 410 to activate the patch. Optionally, squeezing the reservoir 307, 308, 309, 310, 407, 408, 409, 410 pressurizes and/or drives fluid from the reservoir 307, 308, 309, 310, 407, 408, 409, 410 across a valve 311, 312, 313, 314, 411, 412, 413, 414 into the volatilization area 303. Alternatively or additionally, a barrier 316, 317, 318, 319, 320, 416, 417, 418, 419, 420 between functional portions of a patch may be formed by glue and/or heat welding, etc. For example, in the exemplary embodiment of FIG. 3 separation 316, 317, 318, 319, 320 between reservoirs 307, 308, 309, 310 may be via heat welding the base to the cover thereby dividing the compartments. Alternatively or additionally, the cover 302 may be welded to the base 301 around the edges of the device, for example to prevent liquid from leaking out the sides of the device.

In the exemplary embodiment, once the activation tab has been removed, the fragrance can be refreshed with a discreet pressure on the reservoir without having to remove and/or dispose of any materials (such as a cover) and/or without exposing the skin of the user to perfume and/or chemicals. Optionally, the design of the volatilization area and/or valve may facilitate gradual release of volatile substances. For example, this may avoid sudden release of a strong fragrance when the patch is activated.

In some embodiments, a reservoir 307, 308, 309, 310, 407, 408, 409, 410 may include a complete perfume (for example a scent and a volatile solvent). Alternatively or additionally, a volatilization pad 303 may include a scent and/or the reservoir 307, 308, 309, 310, 407, 408, 409, 410 may include a solvent. Alternatively or additionally, a volatilization pad 303 may include a solvent and/or the reservoir 307, 308, 309, 310, 407, 408, 409, 410 may include a scent. For example, when the pad 303 begins to dry and/or the scent becomes weak solvent can be added to the pad 303 to freshen up the pad 303 and increase the strength of the fragrance. In some embodiments, a fragrance and/or a contents of a reservoir 307, 308, 309, 310, 407, 408, 409, 410 may include between 1 to 3% aromatic compounds and/or between 3 to 8% and/or between 8 to 15% and/or between 15 to 40% or more aromatic compounds. In some embodiments, a scent and/or a contents of a reservoir may include natural and/or artificial musk. In some embodiments, a fragrance and/or contents of a reservoir 307, 308, 309, 310, 407, 408, 409, 410 may include between 1 to 3% musk and/or between 3 to 8% and/or between 8 to 15% and/or between 15 to 40% or more musk. In some embodiments, the base 301, 401 may include a skin attachment surface. For example, the bottom surface of the base 301, 401 may include a skin adhesive (for example 3M™ 1776 Polyester Spunlace Nonwoven Fabric Medical).

Optionally the skin contact surface will include a substrate that is configured to facilitate long term and/or comfortable skin contact, for example the substrate may be soft and/or absorbent. In some embodiments, the adhesive will cover for example between 1/10 to 1/5 the lower face of the patch and/or between 1/5 to ½ and/or between ½ to ¾ and/or between ¾ to 9/10 and/or between 9/10 to all of the lower face.

In some embodiments, a patch may include a single volatilizing area and/or multiple reservoirs may facilitate a long acting patch with a large volatilization area. In some embodiments, the size of the volatilization area may determine the amount and/or rate of volatilization of the scent. For example, a large volatilization area may facilitate a stronger faster acting release of scent. For example, in the exemplary embodiment of FIGs. 3, 4 reservoirs 307, 308, 309, 310 take up between 20 to 40% of the inner surface of the base 301 of the device while the volatilization area 303 may take up between 50 to 80% of the surface area. Optionally, each reservoir 307, 308, 309, 310 may hold between 0.01 to 0.5 ml and/or between 0.5 to 2 ml.

In some embodiments, a patch may be configured to be discreet and/or inconspicuous. For example, the average thickness of the patch between the top (outer) face of the cover 302, 402 and the bottom face of the base 301, 401 may be less than 1 mm and/or between 1 to 3 mm and/or between 3 to 5mm and/or between 5 to 8 mm. For example, the center of the patch may be thick and/or the edges may be thin. For example, an adhesive skirt may enhance stability of adhesion of the patch to the skin of a subject. For example, a maximum thickness of the patch may range between 1 to 3 mm and/or between 3 to 5mm and/or between 5 to 8 mm. For example, the maximum thickness of the patch may be at the location of the barrier strip 315, 415 separating the reservoirs from the volatilization area. Optionally the top of the barrier strip may have a variable height. For example, the strip may have a maximum height towards the center of the patch and taper off as it approaches the ends of the strip at the end edges of the patch. In some embodiments a scent and/or contents of a reservoir 307, 308, 309, 310, 407, 408, 409, 410 may in include oil and/or wax. For example, a highly viscous wax and/or oil may be used to slow volatilization. Optionally when the patch warms up (for example under heat and/or during exercise), viscosity is reduced and the rate of release of scent and/or the rate of odor control is increased.

FIG. 5 is a block diagram of an odor controlling patch in accordance with an embodiment of the current invention. In some embodiments, a valve 500 supplies fluid communication between a flexible reservoir 501 and a volatilization area 502. Optionally when a user puts pressure on the reservoir 501, fluid is driven from the reservoir 501 to the volatilization area 502 and/or the fluid there is volatilized to produce a scent. In some embodiments, the volatilization area 502, valve 500 and/or reservoir 501 are all positioned on a flexible substrate 503. Optionally, the substrate 503 includes an adhesive 504. For example, the adhesive 504 may attach the substrate 503 to the skin of a user.

In some embodiments, the exemplary patch of FIG. 5 may be used to produce a scent on demand of a user. For example, a user may be standing on a bus and/or sitting in a meeting near a person with an unpleasant odor. The user may activate the patch by discreetly pressing the reservoir 501 of the patch to release perfume to the volatilization area 502 such that it is volatilized to freshen the air. Alternatively or additionally, a user who is hurrying from a far away parking space on a hot, sunny day to an important meeting may activate the patch. Should it become necessary to freshen up the atmosphere as the meeting progresses, the user may again discreetly volatilize further scent. In some embodiments, the patch may be activated by pushing against clothing covering the patch from outside the clothing.

FIG. 6 is a block diagram of an odor controlling patch in accordance with an embodiment of the current invention. In some embodiments, a one-way valve or conduit

600 supplies fluid communication between a flexible reservoir 601 and a volatilization area 602. Optionally when the reservoir 601 is stressed (for example when a wearer is undergoing heavy exercise), fluid moves between the reservoir 601 and the reservoir

601 and the volatilization area 602. Optionally the one-way valve 600 causes the net movement to be from the reservoir 601 to the volatilization area 602. The rate of movement may be proportional to the amount of stress. In some embodiments, the volatilization area 602, one-way valve 600 and/or reservoir 601 are positioned on a flexible substrate 603. Optionally, the substrate 603 includes an adhesive 604. For example, the adhesive 604 may attach the substrate 603 to the skin of a user. FIG. 7 is a block diagram of an odor controlling patch in accordance with an embodiment of the current invention. In some embodiments, an elastic reservoir 701 drives an activation agent and/or scented fluid toward a volatilization area 702. Optionally, a valve 700 is designed to control the rate of release on the activation agent and/or fluid to a volatilization area 702. Alternatively or additionally, the rate of release may be sensitive to other factors. For example, the rate of release may be sensitive to the viscosity of the contents of the reservoir. For example, the viscosity may be sensitive to heat such that more scent is released as the patch heats up. Alternatively or additionally, the patch may be configured not to be sensitive to heat and/or movement. In some embodiments, the volatilization area 702, rate control conduit 700 or valve and/or elastic reservoir 701 are positioned on a flexible substrate 703. Optionally, the substrate 703 includes an adhesive 704. For example, the adhesive 704 may attach the substrate 703 to the skin of a user.

FIG. 8 is a chart illustrating an exemplary time dependent rate of a release of a scent in accordance with an embodiment of the current invention. The chart’ s x-axis 801 represents elapsed time using hours as the unit of time. The chart’s y-axis 802 represents the rate of release of the scent. For example, user may adhere 803 a patch to his skin in the morning (time 0). When the user puts on the patch, he optionally opens a seal and the patch gives over a scent. Over a few hours, the level of scent goes down as a volatilization area of the patch dries up. Optionally, when the user goes to work (time 2), the heat and exertion of the trip and/or other movement and/or an increase in moisture on the skin of the user causes increased rate 804a of release of the scent for another few hours. Optionally as the strength of the scent decays 805a (e.g. time 4 to time 6), the user activates (e.g. time 6) a second reservoir of scent (for example as described in any of the embodiments herein above and/or below, for example to prepare for an event for example a meeting at work). Activating the reservoir causes an increase 804b in the smell for a few more hours after which the level of release may again decay 805b (time 9 to 11). After a few hours the user may activate (e.g. time 11) a third reservoir (for example as described in any of the embodiments herein above and/or below, for example to prepare to increase 804c a rate of release for an event for example a meeting a spouse upon return home).

FIG. 9 is a schematic illustration of a patch having multiple reservoirs 903, 904, 905, 906, 907, 908 connected to a single volatilization area or zone 901 in accordance with an embodiment of the current invention. The functional zones (reservoirs 903, 904, 905, 906, 907, 908, volatilization area 901) are optionally distributed along the surface of the patch. The majority of the surface is used by the volatilization area 901. Optionally having a large volatilization surface area allows a high rate of volatilization and/or replenishing the volatilization area 901 facilitates scent control over a long period of time. In some embodiments, functional areas (reservoirs 903, 904, 905, 906, 907, 908, volatilization area 901) may be delimited on a substrate 902.

FIG. 10 is a schematic illustration of a patch having multiple reservoirs 1001,

1002, 1003 connected to a single volatilization area or zone 1004 in accordance with an embodiment of the current invention. The functional zones (reservoirs 1001, 1002,

1003, volatilization area 1004) are optionally distributed in layers and along the surface of the patch. For example, a volatilization layer 1004 on an outer surface of the patch is underlain by multiple reservoirs 1001, 1002, 1003 in a deeper layer. For example, putting the at least some of the reservoirs 1001, 1002, 1003 in a layer separate from the volatilization area 1004, the surface area of the volatilization area 1004 may be increased. Alternatively or additionally, without increasing the size of the patch, by distributing multiple reservoirs in a single layer, the thickness of the patch may be reduced.

In some embodiments, a patch may have additional functional units. For example, a lower layer of the patch 1005 may include substances that contact the skin. For example, the bottom layer of the patch 1005 may include an antiperspirant and/or a solvent and/or an absorbent material and/or an antibacterial material and/or a skin conditioner (for example a moisturizer e.g. Aloe Vera) and/or a skin balm. Alternatively or additionally, the bottom layer of the patch 1005 may include a channel and/or a reservoir which is sensitive to heat and/or to moisture. One or more adhesives 1006, 1007 may be placed on a portion of a skin contact surface. Optionally, the patch may have one or more flexible outer skirts 1008, 1011 for example, to increase its stability and/or adhesion to the skin. Optionally, one or more adhesives 1006, 1007 may cover only a part of the skin exposed surface of the patch. For example, the partial coverage of the one or more adhesives 1006, 1007 may let the skin breathe and/or dry and/or stretch. For example, this may make the patch more comfortable and/or avoid skin damage and/or avoid a negative skin response for instance that may cause the patch to be removed. In some embodiments, at least some functional areas (reservoirs 1001, 1002, 1003) may be delimited on a substrate 1009. Alternatively or additionally, the patch may include a cover 1010.

FIG. 11 is a schematic illustration of a patch having multiple volatilization areas 1101, 1102, 1103 distributed in layers of the patch in accordance with an embodiment of the current invention. Optionally, each volatilization layer is preloaded with a scent and/or volatilization agent. For example, when a user desires to refresh the action of the patch he may activate a lower layer by peeling off an upper layer. In some embodiments, at least some functional areas (volatilization areas 1101, 1102, 1103) may be delimited on a substrate 1104. Alternatively or additionally, the patch may include a cover 1105. In some embodiments, a patch may have additional functional units. For example, a lower layer of the patch 1106 may include substances that contact the skin. Alternatively or additionally, one or more adhesives 1107, 1108 may be placed on a portion of a skin contact surface.

FIG. 12 is a schematic illustration of a patch having multiple volatilization areas or zones 1201, 1202, 1203, 1204 in accordance with an embodiment of the current invention. For example, multiple volatilization zones 1201, 1202, 1203, 1204 may be distributed along the surface of a lower substrate 1205. Optionally, each volatilization zone is preloaded with a scented content. Optionally, the substrate acts as a barrier sealing the bottom of the volatilization zones and/or a top barrier 1206 seals the tops of the volatilization zones.

In some embodiments a plurality of deployment openings 1207, 1208, 1209, 1210 in the top barrier 1206 are configured to release a scent from each volatilization zone 1201, 1202, 1203, 1204. Optionally each opening 1207, 1208, 1209, 1210 may have a peel off activation tab or cover 1214, 1215, 1216 blocking the opening. For example, when a user wants to release a scent, he may uncover one or more of the openings 1207, 1208, 1209, 1210. For a stronger scent the user may open multiple openings 1207, 1208, 1209, 1210. Optionally, each volatilization area may include the same contents. Alternatively or additionally, different volatilization chambers may be preloaded with different scents.

In some embodiments the lower substrate 1205 includes at least one adhesive 1211, 1212. For example, the adhesives 1211, 1212 may attach the lower substrate 1205 to the skin of a user. Optionally, the adhesives 1211, 1212 are covered by an adhesive liner 1213 which may be peeled off before applying the patch onto the skin of a user. FIG. 13 illustrates aroll 1301 of patches 1302 in accordance with an embodiment of the current invention. Optionally the roll 1301 may be packaged in a box for easy distribution. For example, the box may include a cutter. Optionally, the box and/or the roll 1301 and/or the patches 1302 may be decorated. For example, the patch may include expensive materials such as velvet and/or felt and/or gilted letters and/or proprietary symbols for example in accordance with the perfume packaged in the patch.

In some embodiments, patches may be arranged in a one or two dimensional array on a backing 1303. For example, FIG. 1, patches are arranged in a one-dimensional line along a rolled up strip. Alternatively or additionally, groups of patches may be arranged along the strip. For example, the strip may be divided into sections, each section having 4 patches of different perfumes to give out as a sample.

In some embodiments, the patches may include adhesive which adheres (reversibly and/or irreversibly) to the backing. Optionally the backing may have the form of a strip and/or may be rolled up. Alternatively or additionally, an array of patches may be folded.

In some embodiments, a patch may be removed from a backing 1303 and mounted to a user. Alternatively or additionally, a backing 1303 may be designed for separation and/or distribution. For example, the backing 1303 may include perforations for easy tearing into parts. Alternatively or additionally, an array of stickers may be packaged in a package designed for separating the array (for example, the array may include a cutter). Optionally patches of different scents and/or strengths may be included on a single backing 1303.

FIG. 14 illustrates a method of applying a scent in accordance with the current invention. For example, in some embodiments, a patch may be mounted on a person 1401, for example by attachment to the skin and/or clothes and/or an ornament of the person. For example, the patch may be attached to a person and/or his clothes and/or his belongings and/or his clothes via an adhesive and/or a clip and/or a pin and/or a ring and/or a magnet and/or a hook and/or a reversible connector and/or an irreversible connector and/or a reversible connector. Alternatively, a piece of clothing and/or an ornament may include a pocket and/or a hollow to hold a sticker. The scent of the patch may be activated 1402 at a selected time to for example to cover an odor and/or when a pleasant smell is desired. Optionally, the patch may be activated with different scents and/or strengths according to need. In some embodiments, an ornament may be designed for use with a scent patch. For example, a bracelet and/or a pin may include a large hidden surface for attaching a scented sticker. Optionally, an embodiment of a patch and/or method of the current invention may be used by persons with allergy to ingredients of a perfume to use the perfume without the perfume contacting the user’s skin.

Optionally a patch may have multiple reservoirs of scent, volatilization material and/or activator. For example, after activation a strength of a scent may dwindle, a further reservoir may be activated, refreshing the scent 1403.

FIG. 15 illustrates a method of using a perfume patch in accordance with some embodiments of the current invention. In some embodiments, a roll of patches may be used for free samples. For example, a customer interested in buying perfume (in a liquid form and/or a box of patches) may be given one or a few patches to try out 1501. Optionally a substrate may include repeated arrays of an assortment of different patches, for example different fragrances, and/or may be divided to separate and/or give out the assortment 1502 (e.g. as a perk and/or as a sample).

In some embodiments, a perfume patch may be used as a perk. For example, a customer buying a piece of jewelry and/or anyone who comes to visit a store at on a certain time may be given a few patches as a perk .

FIG. 16 is a schematic exploded view of a perfume patch in accordance with some embodiments of the current invention. In some embodiments, a movable selector element 1601 may selectively connect between one or more reservoirs 1602, 1603,

1604, 1605, 1606 and a volatilization zone.

In some embodiments, a selector may include a rotating element 1601. For example, the rotating element 1601 may include multiple reservoirs 1602, 1603, 1604,

1605, 1606. Rotating the selector optionally connects and/or disconnects a reservoir 1602, 1603, 1604, 1605, 1606 with the volatilization area. Optionally, each reservoir 1602, 1603, 1604, 1605, 1606 may include a solvent which wets and/or activates perfume in the volatilization area. Alternatively or additionally, each reservoir may include a fragrance (the fragrance and/or strength may be the same in all of the reservoirs and/or may differ).

In some embodiments, a volatilization area includes a perfume pad 1607 positioned on a substrate base 1608. For example, the base 1608 may include a hollow area 1609 in which the pad 1607 sits. The hollow area 1609 is optionally surrounded by a divider 1610. For example, the divider may include an opening 1611 through which fluid from a reservoir 1602, 1603, 1604, 1605, 1606 may enter the hollow area 1609 and/or wet the perfume pad 1607. Optionally, when the perfume pad is wet by the fluid in a reservoir, a fragrance is released through perforations 1612 in an outer face 1613 of the patch. For example, the perforations 1612 may be located above the volatilization zone.

In some embodiments, a rubber seal 1614 prevents leaking of the solvent. Alternatively or additionally, the seal may initially close the divider opening 1611. For example, when the selector is initially moved, the seal may be pushed out of the opening allowing fluid to enter the volatilization area from a reservoir 1602, 1603, 1604, 1605, 1606 that is initially positioned with its opening at the opening of the divider 1611. Wetting the volatilization area may optionally start releasing fragrance. Subsequently, user may refresh the fragrance by rotating the selector to position an opening 1615, 1616 of a new reservoir 1602, 1603, 1604, 1605, 1606 at the divider opening 1611 to add new fluid to the volatilization area, for example to renew the fragrance.

In some embodiments, matching interference elements may position the rotating element at stopping points with each reservoir opening aligned to the divider opening. For example, the interference elements may include a selector stop 1617 and/or a guide slot 1618. In some embodiments, the base may include clasps 1619 that hold the selector to the base 1608. For example, the clasps 1619 may include flexible interference elements that allow the selector to move (e.g., rotate) but prevent the selector from separating from the base 1608.

In some embodiments, a selector and/or a base 1608 may be made of molded plastic. Optionally a face of the patch is made of foil (for example aluminum and/or plastic). For example, the face may be adhered to the selector.

FIG. 17 is a schematic perspective view of a perfume patch in accordance with some embodiments of the current invention. The assembled patch is shown from the outside. For example, a skin contact zone of the base 1701 faces into the page and the perforations 1702 of the outer face 1703 of a rotating selector 1704 of the patch are seen facing out of the page.

FIG. 18 and 19 are schematic cutaway views of a perfume patch in accordance with some embodiments of the current invention. It is seen how the selector clasp 1801, 1901 of the divider 1804, 1904 optionally holds the selector to the base 1802, 1902 of the patch. The rotating selector 1803, 1903 optionally rotates to position each reservoir opening at the divider opening. Optionally the divider 1804, 1904 interferes with flow between a solvent reservoir 1905 and a perfume pad 1806, 1906. Optionally the outer face 1807, 1907 is perforated. Optionally a seal 1908 is located between a reservoir and a volatilization area. Optionally the seal 1908 prevents leaking of the solvent. Alternatively or additionally, the seal may initially close the divider opening.

FIG. 20 is a schematic overhead cross-sectional view of a perfume patch in accordance with some embodiments of the current invention. In some embodiments, an active (in use) reservoir 2001 is in fluid communication with the volatilization area. For example, when the reservoir opening 2002 is aligned with the divider opening 2003 of a divider 2004, fluid communication passes through the openings between the reservoir and the volatilization area. Other reservoirs whose openings are not aligned with the opening in the divider are optionally not in fluid communication with the volatilization area. Optionally the interference elements may include a selector stop 2006.

FIG. 21 is a top perspective view of a perfume patch in accordance with an embodiment of the current invention. In some embodiments, a patch may include an adhesive base 2204 for holding a patch to the skin of a user. In some embodiments, the patch may include a perfume pad 2206 (for example including a cotton sponge impregnated with a fragrance). Optionally there are five reservoirs 2203 connected to the perfume pad 2206. The reservoirs 2203 are optionally sealed by a cover 2202. For example, the cover 2202 is optionally sealed over an opening of the reservoirs 2203. For example, sealing may be through ultrasonic welding. Optionally, each reservoir 2203 is associated with an activation tab 2212.

In some embodiments, a user activates the patch by pulling a tab 2212. For example, each reservoir 2203 may include a volatilizing agent (e.g. a volatile solvent). Each tab 2212 may be attached to a plug that serves as a valve preventing the volatilization agent from reaching the perfume pad 2206. When the tab 2212 is pulled away from the patch, it optionally pulls out the plug and/or causes a release of the volatilization agent to the perfume pad 2206 causing volatilization of the fragrance.

FIG. 22 is a side view of a perfume patch of FIG. 21 in accordance with an embodiment of the current invention. In some embodiments, a base cover is sealed over the bottom of the patch and/or attaches the body 2204 of the patch to the adhesive 2204. FIG. 23 is a top perspective view of components of a perfume patch in accordance with an embodiment of the current invention. In some embodiments a path body 2204 includes chambers for the volatilization area 2205 and five reservoirs 2203. For example, the volatilization area 2205 is configured to hold the perfume pad 2206. Optionally, a respective channel 2215 connects between each reservoir 2203 and the volatilization area 2205. When the patch is assembled, a plug end 2211 of each tab 2212 optionally serves as a valve blocking the respective channel 2215. When the tab 2212 is pulled away the plug end 2211 is pulled away allowing the volatilization agent to pass through the channel 2215 to the volatilization area 2205 and/or to soak the pad 2206 and/or to release the scent.

It is expected that during the life of a patent maturing from this application many relevant scents, volatilization means, adhesives etc. will be developed and the scope of the terms are intended to include all such new technologies a priori.
