The field of the invention is an eyelash extension system and method for applying same, and more particularly but not exclusively, artificial lashes having a pre-applied adhesive element.
Artificial eyelashes are popular products that are used to improve the look of a user's lash line through the addition of lash length and/or volume. Such artificial eyelashes typically comprise a lash line strip with eyelash filaments extending from there. The eyelash filaments can be made from mink, synthetic materials, horsehair, and in some instances, human hair. Artificial eyelashes are typically applied by spreading adhesive on or around the lash line strip component of a lash extension and pressing the lash line strip to a user's lash line or proximate thereto. Such eyelash extensions can be difficult to apply and require that a user have access to both the extensions and specialized adhesives.
More recently, do-it-yourself, under-lash eyelash extension systems have been developed. In these systems, a strip of eyelash extensions is glued to the underside of a user's natural eyelashes in a similar fashion to more traditional above-lash extension systems. The do-it-yourself systems often come in small sections (e.g., wisp lashes, cluster lashes, individual lashes), allowing for an inexperienced user to apply the eyelash extensions without the difficulty of aligning a longer, single strip of eyelash extensions. However, these do-it-yourself systems still require the user to have and apply specialty adhesive either to their lashes or to the lash extension system before use.
A need exists in the art for eyelash extension systems that eliminate the difficulties of prior art systems. A need also exists for a means that easily facilitates a user to apply eyelash extensions without the drawbacks of existing systems.
An object of the invention is to create eyelash extensions that overcome many of the drawbacks in the prior art. A feature of the invention is that the eyelash extensions have pre-applied adhesive elements before being packaged for sale to a user. An advantage of the invention is that the eyelash extension system is ready to use without the need for any additional supplies such as glue. An additional advantage of the invention is that the user can apply the invented eyelash extension system quickly and with one hand.
A further object of the invention is to provide a ready-to-use eyelash extension system having a pre-applied adhesive that is easy for a user to apply. A feature of the invention is that the pre-applied adhesive is droplets of adhesive applied to the eyelash filaments of the eyelash extension system. Alternatively, the invention features double-sided tape as the pre-applied adhesive. An advantage of the invention is that users can apply the invented lash extension system without modifying the pre-applied adhesive.
Another object of the invention is to maintain a ready-to-use eyelash extension system in usable condition before use. A feature of the invention is the use of temporary overlayment of a pre-applied adhesive element that is removed before the use of the eyelash extension system. An advantage of the invention is that the pre-applied adhesive elements of the eyelash extension system are maintained in clean condition for use by a user.
Yet another object of the invention is to provide a lash extension system that is easily applied by a user onto their natural lashes. A feature of the invention is that the lash extension system adheres directly to the natural lashes of a user at a position not directly adjacent to the eyelid of a user. An advantage of the invention is that by adhering the lash extension system to the lashes of a user in a position spaced from the eyelid, the user avoids any pain and skin irritation associated with lash systems that are applied to the skin of the eyelid or adjacent thereto.
The invention provides an artificial eyelash extension system comprising a plurality of eyelash filaments, each having a base and a tip; a support strip attached to the bases of the eyelash filaments, an adhesive element applied to the plurality of the eyelash filaments before the artificial extension system is packaged for sale to a user.
Also provided is a method for applying artificial eyelash extensions comprising providing to a user an eyelash extension system already having an adhesive element disposed on the eyelash extension system before being packaged for sale to the user, moving the adhesive element of the eyelash extension system into contact with the user's natural eyelashes.
The invention, together with the above and other objects and advantages, will be best understood from the following detailed description of the preferred embodiment of the invention shown in the accompanying drawings, wherein:
In various embodiments, the invention provides a ready-to-apply eyelash extension system. The eyelash extension system comprises eyelash filaments extending from an eyelash support strip wherein the filaments feature adhesive elements for attachment to the natural eyelashes of a user. The eyelash extension system may be referred to as a lash extension system or an artificial eyelash extension system.
The foregoing summary, as well as the following detailed description of certain embodiments of the present invention, will be better understood when read in conjunction with the appended drawings.
As used herein, an element or step recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural said elements or steps, unless such exclusion is explicitly stated. Furthermore, references to “one embodiment” of the present invention are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Moreover, unless explicitly stated to the contrary, embodiments “comprising” or “having” an element or a plurality of elements having a particular property may include additional such elements not having that property.
The phrases “lash,” “artificial eyelash,” and “eyelash,” as used herein, are interchangeable and refer to an apparatus that is not part of the wearer's body unless specifically indicated otherwise (e.g., phrases such as “natural eyelash” or “user's eyelash” refer to a part of the wearer's body).
Turning to the figures,
While in
As can be appreciated from
The eyelash filaments 14 are made from conventional materials used in eyelash extensions. Suitable materials include materials having an appearance similar to human eyelashes. Exemplary materials include mink, horsehair, human hair, synthetic materials, and combinations thereof.
Materials used in the support strip 12 are well known in the art and include any suitable material for the attaching of the bases of eyelash filaments 14. Exemplary materials include PBT, nylon, cotton, silk, and combinations thereof.
A salient feature of the invented lash extension system 10 is the inclusion of an adhesive element 20 disposed on the eyelash filaments 14. The adhesive element 20 may be applied before the artificial eyelash extension system is packaged for sale to a user, to the plurality of the eyelash filaments. The adhesive element 20 may be applied at a position between the support strip and one-half the eyelash filaments' average length away from the support strip. The adhesive element 20 may be applied continuously to a predetermined location that is less than half of the eyelash filaments' average length away from the support strip. At least some of the adhesive element 20 is applied to the eyelash filaments 14 at the time of manufacturing of the system.
A benefit of the adhesive element 20 is that the lash extension system is ready to use without applying external adhesive, as will be described below.
While the figures depict the lash extension system as being used in conjunction with a full-strip artificial eyelash extension system, the same ready-to-use adhesive concepts may be used in conjunction with artificial eyelash extension systems of various styles, lengths, and sizes, such as smaller “wisp” eyelash systems (e.g., KISS Falscara Eyelash made by Kiss Products, Inc. located in Port Washington, NY) that are segmented versions of a full-strip eyelash systems and whose support strip lengths are one-half to one-fifth of a full-strip eyelash extension system's support strip length, or even smaller “cluster” eyelash systems (e.g., KISS Lash Couture LuXtensions, also made by Kiss Products, Inc.), or the smallest “flare” or “individual” eyelash systems (e.g., KISS i⋅ENVY Ultra Black Flare Short/Medium/Long, KISS i⋅ENVY Ultra Black 3D Individual Lash Medium/Long, all of which are also made by Kiss Products, Inc.) that may include only a few eyelash filaments 14 attached together at their bases.
The adhesive element 20 can be disposed on a plurality of eyelash filaments 14 across the entire length L of the support strip 12 or some fraction of the eyelash filaments 14, such as two-thirds, one-half, or one-third. It will be apparent to one having ordinary skill in the art that the fraction of eyelash filaments 14 having the adhesive elements disposed thereon can be adjusted according to the weight of the section of lash extension system 10 being used. For example, a lash extension system 10 designed for application to all of a user's natural lashes may require that all the eyelash filaments 14 have corresponding adhesive elements. Alternatively, a lash extension system 10 designed for attachment to some lesser portion of a user's natural lashes may only require that one half or a smaller proportion of eyelash filaments 14 bear corresponding adhesive elements.
As depicted in
Suitable adhesives for use in the instant invention include any adhesive that can be applied to the eyelash filaments 14 and retain stickiness while the lash extension system 10 is stored in packaging. Suitable adhesives can be applied to eyelash filaments 14, then stored without drying.
In the embodiment depicted in
In an embodiment, the strength of the adhesion between the adhesive elements 20 and the elongated substrate 52 is tuned by selecting the thickness of an adhesive applied to the surface of the elongated substrate 52 that contacts the adhesive elements 20. Using particular adhesives on the elongated substrate 52, applying a thin layer of adhesive allows for easy removal of the elongated substrate 52 from the adhesive elements 20, while a thicker layer of adhesive will increase the strength of the bond between the elongated substrate 52 and the adhesive elements 20.
In another embodiment, the strength of the adhesion between the adhesive elements 20 and the elongated substrate 52 is tuned by applying a pre-glue (an adhesive that does not completely coalesce during storage of the stored eyelash extension system) to the surface of the elongated substrate 52 that is in contact with the adhesive elements 20.
As shown in
A person having ordinary skill in the art will readily appreciate that the elongated substrate 62 can be positioned across the eyelash filaments 14 anywhere along their length. Preferably, the elongated substrate 62 is positioned with its centerline (line x in
The elongated substrate 62 can be any suitable material for overlaying the eyelash filaments 14 without overly weighing down the lashes and without bending the lashes when worn by a user. Suitable materials for the elongated substrate 62 include double-sided tape and other types of thin strips with adhesives applied to both sides.
A salient feature of this embodiment is the ability of a user to obtain the eyelash extension system 60 and use it without applying their own adhesives either to the system or their lashes. To enable this feature, the eyelash extension system 60 has to be ready to use when desired by a user. As such, the eyelash extension system 60 should not be stuck to undesired surfaces or objects and should feature clean adhesive disposed on the upward-facing surface 66 of the elongated substrate 62. As shown in
The backing 72 is double-sided in one embodiment. The backing 72 can be removably secured to the adhesive distributed over the upward-facing surface 66 of the elongated substrate 62, can be made from any material suitable for the temporary overlayment of the adhesive on the elongated substrate 62. Suitable materials include paper, plastic, fiber, and combinations thereof.
In an embodiment featuring the backing 72, the bond between the backing 72 and the first elongated substrate 62 is weaker than the bond between the first elongated substrate 62 and the eyelash filaments 14. This can be accomplished by forming a permanent bond between the first elongated substrate 62 and the eyelash filaments 14 and a temporary one between the backing 72 and the first elongated substrate 62. Alternatively, the adhesive contacting surface of the backing 72 is scored, frosted, or otherwise treated to prevent over sticking. These configurations are exemplary and not meant to be limiting. A person having ordinary skill in the art will understand that any configuration is suitable wherein the second elongated substrate (backing 72) can be removed from overlayment of the first elongated substrate 62 without ripping the first elongated substrate 62 from the eyelash filaments 14.
The adhesive elements of the lash extension system can contact any portion of the underside of a user's natural lashes 80. Preferably, the adhesive elements of the lash extension system are put into contact with the user's natural lashes 80 such that the support strip 12 of the lash extension system underlies the underside of a user's natural lashes 80 or their eyelid.
A user applying any of the embodiments of the lash extension system described herein using an eyelash applicator such as the KISS Falscara Eyelash Applicator made by Kiss Products, Inc., located in Port Washington, New York. The Kiss applicator is one suitable eyelash applicator for use with the instant invention and is not meant to be limiting. A person having ordinary skill in the art will understand that many false lash applicators are suitable for use with the instant invention. Alternatively, a user may use their hand to grasp the invented lash extension system and move it into contact with the user's natural lashes.
A salient feature of the instant invention is its ready-to-use nature. Prior art lash systems require applying a bonding solution to the lash extensions and/or the natural lashes of a user before application. The pre-applied adhesive elements are suitable for immediate application to a user's lashes without further preparation of the lash extension system or the user's natural lashes.
After moving the lash extension system into contact with their natural lashes, the invented lash extension system will stay in place without any further pressing using their hand or an applicator. Further, no additional bonding solutions need to be applied. Once the invented lash system is in place, the user can optionally use the applicator or hand to adjust the precise position of the lash extension system or firmly squeeze the adhesive elements and natural lashes together. Surprisingly and unexpectedly, the inventors have discovered that the step of firmly pressing together their natural lashes and adhesive elements from the lash extension system is not necessary as it was in prior art systems. Similarly, the instant invention does not require the sandwiching of natural lashes between a lash extension system on the top of the lashes and one on the bottom of the lashes in order to form a lasting bond as is found in the prior art. Another significant feature of the instant invention is that the lash extension systems described herein can be applied using only one hand.
Use of Lash Extensions
The adhesive element may further include a second elongated substrate temporarily overlaying the adhesive disposed on the upward-facing surface of the elongated substrate, and wherein that second elongated substrate is removed before moving the adhesive element of the extension system into contact with the user's natural eyelashes. Where the adhesive elements of the lash extension system shown in
After the application step in
The figures show the eyelash extension system having a length that approximates the length of a user's eyelid. This is exemplary and not meant to be limiting. In an embodiment, a user will apply only one lash extension system that removably underlies all or substantially all of a user's natural lashes. In such an embodiment, a user needs only apply one eyelash extension system to their natural lashes. In alternative embodiments, the length of the support strips will be shorter and will require a user to apply more than one lash extension system in order to removably underlie all or substantially all their lashes. In yet another embodiment, a user will cut a longer strip of lash extension systems into a plurality of lash extension systems having desired lengths, forming a cluster of lash extension systems.
In one embodiment, the steps of use include applying additional glue, drying, and applying heat. The heat-activated adhesive becomes more pliant when heated. In this embodiment, the users will apply heat by using a heat applicator. In one embodiment, the heat applicator is a small heater included in the package. In another embodiment, the source of heat is a force-activated heat pack. In another embodiment, the heat source comprises a layer of material that heats up when exposed to the electromagnetic radiation found in a microwave oven.
When dried on the lashes, the glue is substantially solid. When heated, the glue changes states to a somewhat liquid or soft—jello-like, jelly-like, or pudding-like state. Such a state and is more comfortable to apply to the natural eyelashes.
Briefly, an embodiment provides a method for applying artificial eyelash extensions comprising: providing to a user an eyelash extension system already having an adhesive element disposed on the eyelash extension system before being packaged for sale to the user; and moving the adhesive element of eyelash extension system into contact with the user's natural eyelashes.
In some embodiments of the method, the eyelash extension system comprises a plurality of eyelash filaments, each having a base and a tip; a support strip attached to the bases of the eyelash filaments; and an adhesive element applied, before the artificial eyelash extension system is packaged for sale to a user, to the plurality of the eyelash filaments.
Further, in some embodiments, the user does not apply adhesive to their natural eyelashes. In some embodiments, the adhesive element comprises discrete droplets of adhesive. In some embodiments, the adhesive element is applied to an upward-facing surface of the eyelash filaments. In some embodiments, the adhesive element is applied continuously to a predetermined location that is less than half of the eyelash filaments' average length away from the support strip. In some embodiments, the adhesive element comprises an elongated substrate having a longitudinal axis, an upward-facing surface, a downward-facing surface, and an adhesive disposed on the upward-facing and downward-facing surfaces, and wherein the adhesive on the downward-facing surface contacts the eyelash filaments. In some embodiments, the step of moving the adhesive element of the extension system into contact with the user's natural eyelashes comprises contacting an underside of the user's natural eyelashes with the adhesive disposed on the upward-facing surface of the elongated substrate. In some embodiments, the adhesive element further comprises a second elongated substrate temporary overlaying the adhesive disposed on the upward-facing surface of the elongated substrate, and wherein that second elongated substrate is removed before moving the adhesive element of the extension system into contact with the user's natural eyelashes.
