The field of the invention is an eyelash extension system and method for applying the same, and more particularly but not exclusively, artificial lashes having magnetized components.
Artificial eyelash extension systems 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 eyelash extension systems typically comprise a lash line support 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 generally applied with adhesive.
An alternative to adhesive is an artificial eyelash extension system that employs magnetism. In some instances, the end-user applies an eyeliner or other makeup with metallic powder. Such powder may or may not have magnetic properties, and magnets attached to the eyelash extension system will be attracted to such metal-containing makeup. In other instances, a pair of eyelash systems with magnets attached to their support strips are provided. The end-user applies the eyelash extension systems by sandwiching his/her natural eyelashes between the two extension systems, where the magnets hold the two extension systems together. In these prior art approaches, the magnetic components are found on top of the support strips of the artificial eyelash extension systems. However, because such magnets are glued to or otherwise placed on the exterior surface of the support strip, the magnets may easily fall off the support strip. And because of the magnets' location on top of the support strip, they also cause the support strip to become bulky. This also makes it undesirable to place more than just a few magnets along the support strip because doing so would increase the bulk. This, in turn, increases the size of each magnet so that sufficient magnetic strength can be created to hold the eyelash systems in place.
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 incorporates magnetic elements within an artificial eyelash support strip without individually gluing the magnets to the exterior of the eyelash support strip.
An object of the invention is to create eyelash extension systems that overcome many of the drawbacks in prior art. A feature of the invention is that the eyelash extension systems have integrated magnetic components to lessen the bulk present in the prior art systems. An advantage of the invention is that the eyelash extension system can be manufactured without the time-consuming step of adhering magnetic elements to the exterior of an eyelash support strip. An additional advantage of the invention is that the magnetic elements are securely embedded in the eyelash support strip.
A further object of the invention is to provide a support strip of artificial eyelash extension systems with magnetic elements that are fast to manufacture. A feature of the invention is that magnetic elements are added to the support strip during the manufacturing of the artificial eyelash extension systems. An advantage of the invention is that the manufacturing of the artificial eyelash extension systems does not add steps at the end of the manufacturing process.
Another object of the invention is to create an artificial eyelash extension system where the magnetic elements will not fall off. A feature of the invention is the full or partial integration of magnetic elements into the support strip. An advantage of the invention is that the magnetic elements are not sitting on the exterior of the support strip of the artificial eyelash extension system and are kept in place within the interior of the eyelash support strip in one embodiment.
Another object of the invention is to create artificial eyelash extension systems with magnetic features, which are nonetheless flexible; a feature of the invention is that the magnetic elements are as small as possible.
Yet another object of the invention is to provide an artificial eyelash extension system that is more lightweight than the prior art systems by using smaller magnetic elements.
Yet another advantage of the invention is that the corresponding quantity of eyeliner containing metallic powder can be lessened because the magnetic properties of the support strip are more evenly distributed along the entire length of the support strip.
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 magnetic elements are used 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,
As shown in
In another embodiment (not shown), the eyelash filaments 14 are substantially parallel and may comprise only a single layer.
In the embodiment shown in
In prior art approaches, as exemplified in
The embodiment 10 of
The layer also includes a strip of double-sided tape 22. The double-sided is overlaid over the eyelash filaments 14, when forming the first layer 20.
In the embodiment of the first layer 20 shown in
The first layer 20 includes a first thread 24 and optionally a second thread 26. The second thread 26 may also be placed after a second layer of eyelash filaments 34 is applied to the first layer 20, as will be shown later. The threads are mounted on the eyelash filaments 14 and glued thereon. Disposed between the first thread 24 and the second thread 26 are the magnetic elements 29. In the depicted embodiment, the magnetic elements 29 comprise blocks having dimensions of between 0.25 mm to 1.5 mm. In one embodiment, the magnetic elements 29 comprise a set of magnetic cuboids having approximate dimensions of 1 mm width, 1 mm length, and 0.4 mm in height. In this context, approximate dimensions refer to ones that can be achieved using standard manufacturing procedures, where margins of ten percent are acceptable.
In the embodiment of the first layer 20 shown in
Multiple placements of the magnets are possible. For example, each magnetic element is coupled to space on the filaments between the first thread 24 and the second thread 26. In that space, each magnet is glued to the eyelash filaments 14. As another example, as shown in FIG. 2A1, magnets may also be placed in locations between the first thread 24 and the second thread 26 where there are no eyelash filaments 14 so that the magnets are placed in a horizontal direction with respect to the eyelash filaments 14, as opposed to being adhered on the filaments in a vertical orientation, so as to decrease the overall thickness of the extension system. Further, the magnets may be placed across either or both the first thread 24 and the second thread 26 so that the magnets protrude out of either or both threads 24, 26 and/or do not fill the space between the threads, as shown in FIGS. 2A2 and 2A3.
A cut line 28 at a point on the eyelash filaments 14 between the second thread 26 and the strip of the double-sided tape 22 is also shown in
In one embodiment, the eyelash filaments 14 are placed on a work surface in the arrangement shown in
In this embodiment, the first thread 24 and the second thread 26 form raised limiting lines for the glue added to the eyelash filaments 14. In one embodiment, especially the first thread 24 forms a boundary for the glue to ensure that the glue stays near the bases 16 of the eyelash filaments 14.
A benefit of the addition of one or more threads is to ensure that the support strip is not excessively flexible. If the glue were applied directly to the filaments, the filaments could bend and may curl excessively upon drying. As such, the addition of the first thread 24, either alone or in conjunction with the second thread 26 provides for consistent placement of the liquid glue. It provides structural integrity to the strip of the artificial eyelashes.
Following the placement of the threads and the glue, the magnetic elements are added. In one embodiment, the magnetic elements comprise rare-earth magnets and are placed in the space between the threads. Additional glue can then be applied in the area between the thread and the strip of the double-sided tape.
In another embodiment (not shown), the magnetic elements are embedded into or otherwise added to a layer of lace, such as a segment of fine lace fabric, added on top of the eyelash filaments or where the eyelash filaments are tied or otherwise adhered to the layer of lace.
A second layer of the eyelash filaments is then applied. In one embodiment, the second layer filaments are oriented so as to cross the first layer. The two layers are shown in
Turning to
A cut line 38 is defined in the second layer along the lengths of the eyelash filaments 34 in a similar manner as the cut line 28 of
The second layer filaments 34 are added over the first layer of eyelash filaments 14 using any number of techniques, including folding them over, machine and manual distribution, and others.
After the addition of the second layer and the formation of the two-layer construct 30, a quantity of glue is added in one embodiment. The glue may be mixed with and contain metallic powder; the powder may have inherent magnetic properties, which provide additional magnetic attraction force to the support strip. In other embodiments, the glue is not added if sufficient glue was already applied to the first layer 20.
Once the glue in the construct 30 dries, a cut is made along the cut line 38, which will correspond to the cut line 28 of the first layer.

Other options for the order of adding various elements of the present invention are shown in
Depending on the number of eyelash filaments, in some embodiments only one thread is used. The embodiments shown in
In another embodiment, the applied glue has a gel-like consistency and does not spread without the application of external pressure. Such a gel-like glue will remain in place without the need for multiple threads to limit spreading. In one embodiment, a thickener is added to conventional glue. In another embodiment, the glue includes a variety of additives, including stabilizers, plasticizers, and pigments. In another embodiment, the glue includes reinforcement fibers, which allow a thin line of the glue to act as a support strip.
Although exemplary implementations of the invention have been depicted and described in detail herein, it will be apparent to those skilled in the relevant art that various modifications, additions, substitutions, and the like can be made without departing from the spirit of the invention. These are therefore considered to be within the scope of the invention as defined in the following claims.
In the embodiments shown above, the magnetic elements comprise magnets having a rectangular or square profile, with the longest side not exceeding 1.5 mm in length, in one embodiment. In another embodiment, the magnetic elements comprise magnets having a substantially square profile, with each side being approximately 1 mm. In another embodiment, the magnetic elements are provided by a magnetized iron powder, such as spherical ferromagnetic iron powder. In one embodiment, the powder comprises Neodymium-iron-boron alloy (NdFeB), but any biocompatible powders or chips which can be magnetized or chips are used. In another embodiment, the magnetic elements may consist only of magnetic powders mixed with and contained in the glue that forms the support strip of the eyelash extension system, enabling a thinner overall profile.
While in the embodiments shown above, the magnetic elements are shown as placed in the space between the two threads, the placement of the magnetic elements need not be performed with a high degree of precision. As such, some magnetic elements may overlap with one or more threads. In one embodiment, all of the magnetic elements are placed on top of one of the threads. This is because the magnetic elements are subsequently covered by the second layer of eyelash filaments, and so the alignment need not be completely precise.
Use of Artificial Eyelashes with Magnetic Elements
During use, the end-user must first apply an appropriate base, such as an eyeliner to allow the magnetic elements to function. In one embodiment, the packaging for the magnetized artificial eyelash extension system includes a quantity of eyeliner with embedded metallic powder in quantities sufficient to allow the magnetic elements to be attracted to the wearer's body, such as the skin.
In one embodiment, the base does not include a dye and is instead the same color as the end user's skin. In most instances, the magnetic powder is in the form of microspheres, and so the powder will apply only a subtle color to the base.
After the base has dried on the user's body, the user can apply the support strip of the eyelash extension system to the desired location, making contact between the user's body and the support strip. A benefit of the magnetic features of the eyelash support strip is that the eyelash extension system may be repositioned on the wearer's body after initial placement.
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 long support strip of lash extension systems into a plurality of lash extension systems having desired lengths, forming a cluster of lash extension systems. Other embodiments form a wisp or a flare of eyelash extension systems.
A benefit of the artificial eyelash extension systems with magnetic elements is that the end-user does not need to apply additional adhesive.
Improving Magnetic Performance
In order to increase the magnetic force of the completed product, the eyelash extension system may be made by following the steps below:
First, the initial layer of filaments is placed on the double-sided tape.
Second, the second layer, oriented in the opposite direction of the initial layer, is placed on top of the first layer.
Third, the first thread may be placed on the second layer to prevent the glue from going outside of the desired area when the glue is applied on top of the second layer.
Fourth, the glue is applied on top of the second layer at a location between the first thread and the double-sided tape.
Fifth, when the glue dries, a cut is made in the section between the first thread and the double-sided tape.
Sixth, the second thread may be placed at regular intervals from the band so that the magnets can be placed at certain locations. The magnets may be placed between the band and the second thread. Then, the glue may be applied between the band and the second thread.
In the resulting construct, the magnets would directly contact the eyelid so the magnetic force may be stronger.
The resulting construct is shown in
