Abstract
A semi-permanent lash extension, applied in segments distributed laterally, includes individual filaments of preselected density, length, and curl radius bonded to or embedded into a substrate. Adhesive may be integral with the substrate, applied to it during or after manufacture, or in multiple layers to secure filaments to the substrates or the assembly to lashes of a wearer. Double-sided tape may do both. A semi-permanent lash extension, applied by a consumer, includes a pre-applied adhesive and provides for quick, easy application.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
[0095] It will be readily understood that the components of the present invention, as generally described and illustrated in the drawings herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the system and method of the present invention, as represented in the drawings, is not intended to limit the scope of the invention, but is merely representative of various embodiments of the invention. The illustrated embodiments of the invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout.
[0096] Referring to
[0097] The word “extension” may be used to refer to both an entire set 10 or an individual fiber 14. Context should make it clear. In the illustrated embodiment, the system 10 or extension 10 relies on a substrate 16 such as a band 16 or tape 16. This substrate 16 may be film, may be a polymer, and may at different stages be, for example, an uncured polymer, a B-staged polymer where it is partially cured, or may be a fully cured and therefore mechanically stable polymer. This substrate may be any type of pre-applied adhesive suitable for the intended purpose.
[0098] In the illustrated embodiment of
[0099] In the illustrated embodiment of
[0100] In one embodiment, a synthetic eyelash system 10 may consist of distinct upper and lower segments of lashes. Each segment may have specific characteristics. Any segment may implement an adhesive tape 16 in a specific, prescribed manner. An adhesive tape 16 may be considered as double-sided tape. An adhesive tape may be comprised of poly methyl methacrylate, and may include other compounds. An adhesive 18 that thickens may be used, and an adhesive may be non-Newtonian. In one embodiment, an adhesive may be absent and replaced with a heat fusion process.
[0101] Referring to
[0102] Typically, the band 16 in such an embodiment is on the lower extremum of each filament 14. Thus, adhesive 18 is applied on an upper extremum. As a matter of fact, the band 16 may be melted, injected, or otherwise cured to not only fit below the filaments 14 but to surround them. An adhesive layer 18 may be added to the band 16 at or before the time of application of the system 10 to a user.
[0103] Referring to
[0104] Referring to
[0105] In the illustrated embodiment, a tray 24 or case 24 is provided with stations 25 as depressions 25 or indentations 25 within a material as holders 25 for the different segments 22 to be used in an application. One will note that the density (the number of filaments 14 or fibers 14 per unit of width) along the band 16 of each segment 22 is comparatively sparse. Typically, the overall density desired is somewhat more dense than the natural lashes 12. However, each filament 14 typically has a somewhat greater diameter than that of a natural lash 12. Length is substantially longer than that of a natural lash 12. That's why “extensions” exist.
[0106] In the illustrated embodiment, the band 16 on each segment 22 is covered with a backer 21 protecting the adhesive 18 on the band 16 against contamination, or against other contact. The backer 21 will eventually be removed by a technician before contacting a subject's natural lash 12 by the adhesive 18 on a band 16 of a segment 22. The band 16 may ultimately be used to refer to the entire continuous expanse of individual bands 16 for each segment 22 once applied to natural lashes 12.
[0107] Referring to
[0108] Referring to
[0109] An additional mechanism is found useful in the adhesive 18. If the adhesive 18 is excessively rigid, then adjacent lashes 12, growing at different rates (distance or length per unit of elapsed time) may cause tension or compression by lashes 12 against the eyelid 20. It has been found preferable to use a rheological material such as a rheological adhesive 18 in order to permit a certain amount of creep (permanent deformation of molecules) or even yielding (permanent displacement of atoms) of the adhesive over time.
[0110] By rheological material is meant a non-Newtonian material. Newtonian fluids operate according to conventional rules of viscosity. A fluid, whether gas, saturated vapor, or liquid is defined in the art of fluid mechanics as a material that will move under any amount of stress. How fast such a fluid will respond to shear stress is measured in terms of viscosity. A more viscous material (e.g., honey, heavy oils, etc.) will have a different response from that of a thinner, less viscous, or more inviscid liquid (e.g., water, alcohol, etc.).
[0111] A rheological material may act like a solid, but flow as a non-Newtonian fluid under sufficient stress or prolonged stress.
[0112] For example, rheological materials may operate as solids under a certain amount of stress (where stress is a force per unit of area, whether tension, compression, or shear), but operate as a fluid or somewhat like a fluid under a higher stress. Various varieties of these non-Newtonian materials that can operate as both solids and fluids may involve highly viscous materials, may involve fillers that tend to stabilize a fluid, or may involve Bingham plastics.
[0113] A Bingham plastic is a material that does not move under some predetermined amount of stress, but then begins to flow once that level of stress is exceeded. A filled Bingham plastic may respond to stress by distorting, and even releasing and readhering to a lash 12. Thus, comfort is greatly increased by using a rheological material as the adhesive 18. In this way, materials may be used as adhesives 18 that accommodate the differential growth rates between newer and older natural lashes 12 captured by a single segment 22.
[0114] In addition, the fact that segments 22 need not contact one another, provides for more natural movement of the filaments 14. This provides a decoupling of stresses between different, neighboring, natural lashes 12 emerging from an eyelid 29.
[0115] Referring to
[0116] Accordingly, in the illustrated embodiment of
[0117] Referring to
[0118] A technician, typically in consultation with a subject (wearer) will typically select a length or a range of lengths to be used for the fibers 14 in individual segments 22. Segments 22 may typically be from about three to about seven in number to form one system 10 corresponding to a single eye. It has been found that a group of about six segments 22 covering a distance of about a few dozen millimeters or a few centimeters will typically accommodate the lash 12 of one eye or corresponding to one eye.
[0119] In a method 40 in accordance with the invention, the example of
[0120] A setup 46 by a technician may involve an arrangement of the subject in a comfortable, typically recumbent, position. The head and neck are properly supported to stabilize the face. Stability aids precision and easy access by the technician and comfort of the subject. Likewise, providing the selection of segments 22 at the proper lengths, according to the selections 42, 44 and arranging them in a tray 24 close at hand for easy access by the technician. Similarly, adhesives 18 may need to be provided for in the tray 24, although the illustrated embodiment contemplates an adhesive 18 previously applied to the band 16 of each segment 22, and covered with a backer 21 that may be removed with or without tools.
[0121] Referring to
[0122] The illustrated embodiment illustrates a training template 78 having simulated natural lashes 12 to which a set 23 of segments 22 may be attached in training. The nibs 74 may hold, manipulate, and otherwise move the segment 22 into contact with the lash 12. The adhesive 18 on the band 16 or strip 16 adheres against the lash 12. Typically, if a single set 23 is to be attached to the lash 12, then the segments 22 will typically adhere to the underside of the natural lash 12.
[0123] A cover 20 may adhere opposite the band 16 and adhesive 18. Alternatively, another segment 22 (a dual) having downward facing adhesive 18 may be the cover 20. Another band 16, absent any filaments may be applied as a cover 20 to protect any adhesive 18 exposed between the natural lashes 12. A material to neutralize the adhesive may be painted on, dusted on, or simply result from curing or reacting with the adhesive to form a stable skin thereon.

[0128] Referring to
[0129] Most lashes 12 are enhanced, made to appear thicker, longer, and darker than natural lashes 12. These properties are effected by the length, diameter, color, density, and so forth of the fibers 14 in each segment 22. By the same token, in order to not overwhelm the appearance of the eyes, the density of extensions 10 may be substantially reduced. This is particularly so for the density of individual segments 22 in a “dual” application. Segments 22 are applied in such a dual configuration as under segments 22a and over segments 22b illustrated in

[0134] Referring to
[0135] Typically, the adhesive 18 is sufficiently soft that the pressure of contacting the adhesive 18 and band 16 against the underside of the natural lash 12 will be enough to temporarily support the weight of the segment 22 against the lash 12. Nevertheless, a technician may remove the segment 22 in order to more perfectly locate it, without damage. Ultimately, the segment 22 is placed in contact at a proper location and orientation against the underside of the lash 12. Then the nibs 74 may release the segment 22 and move into position to pressure the lashes 12 into the adhesive 18. This extrusion effects a complete and durable securement of the segment 22 to the lash 12.
[0136] Referring to
[0137] Referring to
[0138] Referring to
[0139] In certain embodiments, various adhesives may be used for various purposes and with various component pieces. Adhesives may be described generally in two categories, liquid adhesives and tape adhesives. Any suitable liquid adhesive 19 may be used. In one embodiment, a first adhesive, or liquid adhesive 19, may be used on natural eyelashes. Such a liquid adhesive 19 may be comprised of water, styrene/acrylates/ammonium methacrylate copolymer, an adhesion promoter, acrylate copolymer, and/or carbon black. The styrene/acrylates/ammonium methacrylate copolymer may be described as a film-forming agent that is water-resistant. In one embodiment, a liquid adhesive may be comprised of 1-methyl-2-pyrrolidone, ammonia (anhydrous), and carbon black. Any suitable tape adhesive may be used, including rheological and non-rheological materials. A tape adhesive may be described as a medical grade adhesive, pressure-sensitive adhesive, double-sided tape with acrylic on both sides. It may be described as a non-Newtonian adhesive compound, or a rheological material. It may include a highly conformable polyethylene carrier for maximum user comfort, and easily die cuttable into various shapes and sizes. The use of a pressure-sensitive adhesive may be helpful because it can allow for some repositioning of an artificial eyelash, or segment, before pressure is applied activating the adhesive and before the artificial eyelash is adhered to the natural eyelash.

[0141] Referring to
[0142] Referring to
[0143] Referring to
[0144] Individual artificial lash segments 22, or one-piece lash segments 100, may be used for different situations and intended uses. For example and not by way of limitation, smaller segments 22 may be easier to apply or position, but may require multiple segments 22 to achieve a desired appearance. Similarly, a one-piece artificial segment 100 may be more difficult to apply or position, but may not require multiple segments to achieve a desired appearance. One may understand that this may depend on adhesives used and desired appearances, which can vary depending on the person applying or using the eyelash extensions.
[0145] Referring to
[0146] Referring to
[0147] Referring to
[0148] Any artificial eyelash, including without limitation, a bottom artificial eyelash 102 and a top artificial eyelash 104 and an artificial eyelash segment 22, may be described as having a proximate end and a distal end. The proximate end may include a band 16 or tape 16, and when applied, the proximate end of the artificial eyelash would be near or adjacent the eyelid of the natural eyelashes. The distal end of the artificial eyelash would be away from the eyelid of the natural eyelash, with the fibers at the distal end loose.
[0149] Referring to
[0150] Natural lashes 12 may be prepared to have extensions, or lash segments 22, or a bottom artificial eyelash 102, applied to them. The natural lashes may be cleaned 122 in any suitable manner. For example, a cleaning solution may be brushed onto the natural lashes so as to remove unwanted oils from the natural lash. In one embodiment, a method for applying an artificial eyelash extension, or segment, or bottom artificial eyelash, to a person may include a preparation step that includes using a primer, or preparatory solvent, that leaves a layer of plastic for the adhesive. An adhesion promoter may include an alcohol that removes oil from the natural lashes prior to placement of artificial eyelash extensions, or segments. An adhesion promoter may also or otherwise include an alcohol that utilizes oil present on the natural eyelashes to facilitate leaving a thin layer of plastic for the adhesive. For another example, the step of cleaning 122 may be as simple as wiping the natural eyelashes 12 with a cloth, dry or damp, to remove dirt or debris.
[0151] A liquid adhesive 19 may be applied 124 to the natural lashes 12. In one embodiment, a liquid adhesive 19 may be applied to prepare artificial eyelashes to be adhered to the natural lashes 12. In another embodiment, a liquid adhesive 19 may be used wherein the liquid adhesive 19 functions to clean the natural lashes, removing unwanted oils from the natural lashes, and to serve as an adhesive. In such an embodiment, a primer may not be necessary. In one embodiment, a liquid adhesive 19 may be applied using a mascara brush, or any other suitable tool or other suitable technique or manner. The liquid adhesive may be comprised of the following: styrene/acrylates/ammonium methacrylate copolymer, water, adhesion promoter, acrylate copolymer, and carbon black. Generally, the liquid adhesive 19 may be applied to the underside of the user's natural eyelash 12, and may be applied primarily at the base of the natural eyelash 12, although this application process may serve to coat the entire base of the natural eyelash with adhesive. The liquid adhesive 19 may be applied in any suitable manner. The liquid adhesive 19 may be described as a relatively thick, liquid adhesive, with a consistency similar to mascara. The use of the liquid adhesive 19 may allow the application process to proceed without the use of alcohol and/or other priming compounds, eliminating the need to prepare 122, or clean 122, the natural eyelash before the liquid adhesive 19 is applied. The elimination of this preparation step 122 can save a considerable amount of time in the application process 120, as well as saving a considerable amount of chemicals that are no longer required to complete the process.
[0152] The liquid adhesive may be allowed to cure 126. The liquid adhesive applied to the natural lashes may be allowed to cure by contact with the air, allowing the liquid adhesive to become tacky. The time to allow for curing 126 may be approximately ten (10) seconds, but may be any suitable time from about two (2) seconds to about sixty (60) seconds.
[0153] A bottom artificial eyelash, or extension, or any artificial lash segment, may be applied 128 to the natural lashes 12 so that the tape affixed to the bottom artificial eyelash, or artificial lash segment, adheres to the liquid adhesive on the natural lash. In one embodiment, a bottom artificial eyelash may include a tape 16 adhesive 18 that is pre-applied to the bottom artificial eyelash 102, or artificial segment 22. The pre-applied adhesive may be in any suitable form, including without limitation, tape, liquid, gel and/or elastic adhesives, and may be an un-cured adhesive. In one embodiment, an adhesive may be absent and replaced with a heat fusion process, which process may also be described as forming a base or substrate 16. Such a bottom artificial eyelash may be configured so that the tape adhesive is already present on the bottom artificial eyelash and readily available to be applied to the natural lash. In the same embodiment or another embodiment, the bottom artificial eyelash may also include a transverse fiber 15 along the bottom of the bottom artificial eyelash. In one embodiment, packaging for artificial eyelash extensions, including without limitation bottom artificial eyelashes, that have been prepared and are ready to be applied to a user or person may be packaged in such a manner so that the backing film 21 for the adhesive tape 16 remains with the packaging as the artificial lash segment, or bottom artificial eyelash 102, is removed from the packaging just before the segment is affixed to the natural eyelashes of a user or person. In one embodiment, the packaging for the artificial lash segment 22, or bottom artificial eyelash 102, may include a backing layer between the packaging base and the tape adhesive 18. The backing layer may remain attached to the packaging base as the artificial lash segment 22, or bottom artificial eyelash 102, is removed from the packaging. The tape adhesive 18 will be exposed in preparation for application 128, and may begin to dry and/or cure as it is exposed to air. The tape adhesive 18 may be pressure-sensitive. The bottom artificial eyelash 102, or artificial eyelash segments 22, may be applied near the eyelid of the user as desired by the user. The tape adhesive 18 on the artificial eyelash should be placed where the liquid adhesive 19 was applied to the natural eyelash 12.
[0154] In one embodiment, the step of applying 128 a bottom artificial eyelash may include selecting an artificial lash segment 22, or bottom artificial eyelash 102. The artificial lash segment 22, or bottom artificial eyelash 102, may be comprised of artificial lashes or fibers 14 bound together in a short segment that may be approximately 1-20 millimeters in length. Also, the artificial lash segment 22, or bottom artificial eyelash 102, may be removed from its packaging in such a manner that a second adhesive 18, or tape adhesive 18, remains attached to the lower portion of the artificial lash segment 22, or bottom artificial eyelash 102, generally along the base of the artificial eyelash extension segment. The artificial lash segment 22, or bottom artificial eyelash 102, may be applied to the underside of a user's, or person's, natural eyelash. The tape adhesive 18 on the artificial eyelash should be placed where the liquid adhesive 19 was applied to the natural eyelash 12. One or more artificial eyelash segments 22 may be applied in a similar manner.
[0155] Pressure may be applied 130 to securely adhere the bottom artificial eyelash, or lash segment, to the natural lashes. Pressure may be applied 130 to thoroughly mix the liquid adhesive on the natural lashes 12 with the tape adhesive on the artificial eyelashes. In one embodiment, the artificial eyelash segment 22, or bottom artificial eyelash 102, now adjacent to the underside of the user's natural eyelash, may be crimped to activate a pressure-sensitive adhesive in the tape adhesive 18. This crimping 130, or applying pressure 130, may activate both the tape adhesive 18 and the liquid adhesive 19 allowing them to adhere together really well, and may allow for proper “mixing” of the adhesives. An artificial eyelash segment 22, or bottom artificial eyelash 102, that is applied and affixed in this manner may be expected to remain adhered to the user's natural eyelash for approximately 7-14 days. The liquid adhesive 19, or first adhesive 19, may adhere or bond better to the natural lashes than the tape adhesive 18, or second adhesive 18. The tape adhesive 18, or second adhesive 18, may adhere or bond better to the artificial lash fibers 14, or artificial eyelashes, than the liquid adhesive 19, or first adhesive 19. During the application process 120, the tape adhesive 18 adheres to the liquid adhesive 19 and may adhere in such a manner that allows the natural eyelashes to adjust, move, and grow in relation to the artificial lash segments 22, or bottom artificial eyelash 102, without pinching or wrinkling that can become uncomfortable for the user. The adhesion between the liquid adhesive 19 and the tape adhesive 18 may be described as a fluid bond that allows for relative movement of natural lashes in relation to the artificial lash segments 22, or bottom artificial eyelash 102. The mechanical surrounding of the natural lashes 12 by the liquid adhesive 19 may be a crucial step for establishing this fluid bond.
[0156] The application process 120, or adhesion process 120, may allow for a certain amount of movement between the adhesive, or adhesives, allowing a certain amount of movement between the natural eyelashes and the artificial eyelashes. In preferred embodiments, a configuration of artificial eyelashes affixed to natural eyelashes may still allow for “creep” of the natural eyelashes such that the natural eyelashes are allowed to grow as normal while the artificial eyelashes are attached without bunching or pinching occurring. The fluid bond of the adhesives may be instrumental in allowing for this “creep” to occur.
[0157] Any artificial eyelashes, or eyelash segments, applied in accordance with the application process 120, or any suitable variation of the process, may be removed by the user. A suitable remover, or remover solution, may be applied to the natural eyelashes 12, for example by brushing the remover solution onto the natural lashes. Any suitable remover solution may be used. A suitable remover solution may be characterized as a solution that weakens, dissolves, or breaks the bond between any adhesives used to adhere the artificial eyelashes to the natural eyelashes. Typically, the remover may be applied to the top of the natural eyelashes where the artificial eyelashes are adhered to the natural eyelashes. The remover should be applied to thoroughly wet the area where the artificial eyelashes will be removed. The remover may be allowed to sit on the eyelashes for a suitable amount of time, usually a few seconds will suffice. After the remover has been allowed to work on the adhesives and weaken the fluid bond, the artificial eyelashes may be removed. It is recommended that a user grab the artificial eyelashes near the base of the artificial eyelashes and gently pull the artificial eyelashes away from the natural eyelashes. The remover solution may be used to remove any residual adhesive on the natural eyelashes. After the artificial eyelashes have been removed, the natural eyelashes should be thoroughly cleaned by any suitable manner to remove any remover solution that may still be on the natural lashes.
[0158] In another embodiment of the application process 120, artificial lash segments 22, or a bottom artificial eyelash 102 and a top artificial eyelash 104, may be applied to a user's natural eyelash using a “sandwich” technique.
[0159] Natural lashes may be prepared to have extensions, or lash segments 22, or a bottom artificial eyelash 102 and top artificial eyelash 104, applied to them. The natural lashes may be cleaned 122 in any suitable manner. For example, a cleaning solution may be brushed onto the natural lashes so as to remove unwanted oils from the natural lash. In one embodiment, a method for applying an artificial eyelash extension, or segment 22, or bottom artificial eyelash 102 and top artificial eyelash 104, to a person may include a preparation step that includes using a primer, or preparatory solvent, that leaves a layer of plastic for the adhesive. An adhesion promoter may include an alcohol that removes oil from the natural lashes prior to placement of artificial eyelash extensions, or artificial segments. An adhesion promoter may also or otherwise include an alcohol that utilizes oil present on the natural eyelashes to facilitate leaving a thin layer of plastic for the adhesive. For another example, the step of cleaning 122 the natural eyelashes 12 may be very simple. A user may wipe the natural eyelashes 12 with a cloth, dry or damp, to remove dirt or debris.
[0160] A liquid adhesive 19 may be applied 124 to the natural lashes 12. In one embodiment, a liquid adhesive 19 may be applied to prepare artificial lashes to be adhered to the natural lashes 12. In another embodiment, a liquid adhesive 19 may be used wherein the liquid adhesive 19 functions to clean the natural lashes, removing unwanted oils from the natural lashes, and to serve as an adhesive. In such an embodiment, a primer may not be necessary. In one embodiment, a liquid adhesive 19 may be applied using a mascara brush, or any other suitable tool or other suitable technique or manner. The liquid adhesive may be comprised of the following: styrene/acrylates/ammonium methacrylate copolymer, water, adhesion promoter, acrylate copolymer, and carbon black. Generally, the liquid adhesive 19 may be applied to the underside of the user's natural eyelash, and primarily to the base of the natural eyelash 12, although this application process may serve to coat the entire base of the natural eyelash with adhesive. The liquid adhesive 19 may be applied in any suitable manner. The liquid adhesive 19 may be described as a relatively thick, liquid adhesive, with a consistency similar to mascara. The use of the liquid adhesive 19 may allow the application process to proceed without the use of alcohol and/or other priming compounds, eliminating the need to prepare 122, or clean 122, the natural eyelash before the liquid adhesive 19 is applied. The elimination of this preparation step 122 can save a considerable amount of time in the application process 120, as well as saving a considerable amount of chemicals that are no longer required to complete the process.
[0161] The liquid adhesive 19 may be allowed to cure 126. The liquid adhesive applied to the natural lashes may be allowed to cure by contact with the air, allowing the liquid adhesive to become tacky. The time to allow for curing 126 may be approximately ten (10) seconds. Any suitable amount of time to allow curing may be used, including without limitation approximately two (2) seconds to approximately sixty (60) seconds.
[0162] A bottom artificial eyelash 102, or extension, or any artificial lash segment, may be applied 128 to the natural lashes so that the tape affixed to the bottom artificial eyelash, or lash segment, adheres to the liquid adhesive on the natural lash. In one embodiment, a bottom artificial eyelash 102 may include a tape 16 adhesive 18 that is pre-applied to the bottom artificial eyelash, or segment 22. The pre-applied adhesive may be in any suitable form, including without limitation, tape, liquid, gel and/or elastic adhesives, and may be an un-cured adhesive. In one embodiment, an adhesive may be absent and replaced with a heat fusion process, which process may also be described as forming a base or substrate 16. Such a bottom artificial eyelash may be configured so that the tape adhesive is already present on the bottom artificial eyelash and readily available to be applied to the natural lash. In one embodiment, a top artificial eyelash 104 may include a tape 16 adhesive 18 that is pre-applied to the top artificial eyelash, or segment 22. The pre-applied adhesive may be in any suitable form, including without limitation, tape, liquid, gel and/or elastic adhesives, and may be an un-cured adhesive. In one embodiment, an adhesive may be absent and replaced with a heat fusion process, which process may also be described as forming a base or substrate 16. In the same embodiment or another embodiment, the bottom artificial eyelash may also include a transverse fiber 15 along the bottom of the bottom artificial eyelash 102. In one embodiment, packaging for artificial eyelash extensions, including without limitation bottom artificial eyelashes, that have been prepared and are ready to be applied to a user or person may be packaged in such a manner so that the backing film 21 for the adhesive tape 16 remains with the packaging as the artificial lash segment, or bottom artificial eyelash, is removed from the packaging just before the segment is affixed to the natural eyelashes of a user or person. In one embodiment, the packaging for the artificial lash segment 22, or bottom artificial eyelash 102, may include a backing layer between the packaging base and the tape adhesive 18. The backing layer may remain attached to the packaging base as the artificial lash segment 22, or bottom artificial eyelash 102, is removed and may begin to dry and/or cure as it is exposed to air. The tape adhesive 18 may be pressure-sensitive. The bottom artificial eyelash 102, or artificial eyelash segments 22, may be applied near the eyelid of the user as desired by the user. The tape adhesive 18 on the artificial eyelash should be placed where the liquid adhesive 19 was applied to the natural eyelash 12.
[0163] In one embodiment, the step of applying 128 a bottom artificial eyelash and a top artificial eyelash, may include selecting artificial lash segments 22, or a bottom artificial eyelash 102 and a top artificial eyelash 104. The artificial lash segments 22, or bottom artificial eyelash 102 and top artificial eyelash 104, may be comprised of artificial lashes bound together in a short segment that may be approximately 1-20 millimeters in length, perhaps approximately 10 millimeters in length. Also, the artificial lash segments 22, or bottom artificial eyelash 102 and top artificial eyelash 104, may be removed from its packaging in such a manner that a second adhesive 18, or tape adhesive 18, remains attached to the lower portion of the artificial lash segments 22, or bottom artificial eyelash 102 and top artificial eyelash 104, generally along the base of the artificial eyelash extension segment. The artificial lash segments 22, or bottom artificial eyelash 102 and top artificial eyelash 104, may be applied to the underside and topside of a user's natural eyelash 12. A bottom artificial eyelash 102 is generally applied to the underside of a natural eyelash and a top artificial eyelash 104 is generally applied to the topside of a natural eyelash. One or more artificial eyelash segments 22 may be applied to both sides of a natural eyelash in a similar manner. The artificial eyelash segments may be applied near the eyelid of the user as desired by the user. The tape adhesive 18 on the artificial eyelash should be placed where the liquid adhesive 19 was applied to the natural eyelash 12.
[0164] Pressure may be applied 130 to securely adhere the bottom artificial eyelash and top artificial eyelash, or artificial lash segments, to the natural lashes. Pressure may be applied 130 to thoroughly mix the liquid adhesive 19 on the natural lashes 12 with the tape adhesive 18 on the artificial eyelashes. In one embodiment, the artificial eyelash segments 22, or bottom artificial eyelash 102 and top artificial eyelash 104, now “sandwiched” on both sides of the user's natural eyelash 12, may be crimped to activate a pressure-sensitive adhesive in the tape adhesive 18. This crimping 130, or applying pressure 130, may activate both the tape adhesive 18 and the liquid adhesive 19 allowing them to adhere together really well, and may allow for proper “mixing” of the adhesives. Artificial eyelash segments 22, or bottom artificial eyelash 102 and top artificial eyelash 104, that are applied and affixed in this manner may be expected to remain adhered to the user's natural eyelash for approximately 14-28 days. The liquid adhesive 19, or first adhesive 19, may adhere or bond better to the natural lashes 12 than the tape adhesive 18, or second adhesive 18. The tape adhesive 18, or second adhesive 18, may adhere or bond better to the artificial lash fibers 14, or artificial eyelashes, than the liquid adhesive 19, or first adhesive 19. The liquid adhesive 19 and the tape adhesive 18 bond well to each other, and may be described as forming a fluid bond. During the application process 120, the tape adhesive 18 adheres to the liquid adhesive 19 and may adhere in such a manner that allows the natural eyelashes to adjust, move, and grow in relation to the artificial lash segments 22, or bottom artificial eyelash 102 and top artificial eyelash 104, without pinching or wrinkling that can become uncomfortable for the user. The adhesion between the liquid adhesive 19 and the tape adhesive 18 may be described as a fluid bond that allows for relative movement of natural lashes in relation to the artificial lash segments 22, or bottom artificial eyelash 102 and top artificial eyelash 104. The mechanical surrounding of the natural lashes 12 by the liquid adhesive 19 may be a crucial step for establishing this fluid bond.
[0165] The application process 120, or adhesion process 120, may allow for a certain amount of movement between the adhesive, or adhesives, allowing a certain amount of movement between the natural eyelashes and the artificial eyelashes. This movement may be accomplished, at least in part, because of the fluid bond created by the adhesives. In preferred embodiments, a configuration of artificial eyelashes affixed to natural eyelashes may still allow for “creep” of the natural lashes such that the natural lashes are allowed to grow as normal while the artificial eyelashes are attached without bunching or pinching occurring.
[0166] Some of the benefits to this process 120 may include a more robust adhesion result. Also very important, the result is significantly more comfortable for the user. The comfort level, and the duration of the comfort level, provided by this process 120 is surprising and unexpected as compared to other, previous application techniques or processes.
