  "abstract": "Cases can be used to house sets of artificial lashes in a specified arrangement. For example, lash fusions may be placed within multiple predefined indentations in the shape of an eyelid. Applicators can be used to resiliently grasp all of the lash fusions in a set of lash extensions, and then simultaneously apply the entire set of lash extensions directly to the underside of the natural lashes. An applicator includes opposed arms that are connected to one another at an inner end designed to be gripped by an individual. The applicator can also include an outer end having a concave shape that is contoured to be substantially flush with the convex shape of the lash line and the predefined indentations of a case that includes the set of lash extensions.",
  "claims": [
    "1. A method for attaching artificial lash extensions to the natural lashes of a subject, the method comprising: grasping an applicator having opposed first and second arms joined at proximal ends thereof, the first and second arms each defining: an exterior surface, an interior surface and opposing first and second lateral sides disposed between the interior and exterior surfaces, wherein the interior surfaces of the first and second arms face each other and the arms are biased toward an open configuration in which the arms are spaced apart, each of the first and second arms having a handle portion extending from the proximal end outward to a distal end of the handle; and an applying portion extending outwardly from the distal end of the handle portion, the handle portion defining a first longitudinal axis and a convex arc such that the first lateral side of each arm is convex and the second lateral side of each arms is concave in the handle portion, and the applying portion defines a second longitudinal axis and each provide two crescent shaped portions extending in series from the respective handle portion such that the first lateral sides of each arm provide a pair of concavities facing away from the respective second lateral side and the second lateral side of each arm provides two convexities extending in series opposite the concavities, wherein the longitudinal axis of the applying portions is arranged offset from the longitudinal axis of the handle portion such that the concavities of the first and second arms face the longitudinal axis of the handle portion; applying pressure to the exterior surfaces of the first and second arms of the applicator to securely grasp a set of lash extensions that includes multiple lash fusions between the interior surfaces of a distal-most one of the two crescent shaped portions, wherein the application of the pressure causes the interior surfaces of the first and second arms at the distal-most one of the two crescent shaped portions to engage one another, thereby grasping the multiple lash fusions simultaneously, arranging the set of lash extensions proximate to a tightline of an eyelid of the subject via the opposing arms; attaching the set of lash extensions to an underside of the natural lashes of the subject; and discontinuing to apply pressure to the opposed arms of the applicator.",
    "2. The method of claim 1, further comprising: applying an adhesive to a top side of each lash fusion included in the set of lash extensions prior to performing said attaching.",
    "3. The method of claim 2, wherein the adhesive comprises cyanoacrylate.",
    "4. The method of claim 1, wherein said attaching is enabled by an adhesive coating applied to a top side of each lash fusion included in the set of lash extensions during a manufacturing process.",
    "5. The method of claim 1, further comprising: securing the multiple lash fusions to the underside of the natural lashes of the subject by initiating a second application of pressure to the opposed arms of the applicator, wherein the second application of pressure causes the outer portions of the opposed arms to clamp down on the multiple lash fusions and the natural lashes of the subject.",
    "6. The method of claim 1, further comprising: arranging the applicator over a case that includes the set of lash extensions, wherein the case includes multiple predefined indentations for receiving a lash fusion, and wherein the case includes a convex outer surface on which the multiple lash fusions are arranged, the convex outer surface substantially complementing the crescent shape of the outer portions of the opposed arms.",
    "7. The method of claim 1, further comprising: applying an adhesive to a top side of each lash fusion that allows the set of lash extensions to be applied to an underside of the natural lashes of the subject without requiring manual application of an adhesive to the natural lashes."

  "description_excerpt": "Various embodiments concern cases for housing artificial eyelashes and applicators for applying artificial eyelashes to the underside of an individual's natural eyelashes.\n\nEyelash extensions have conventionally been used to enhance the length, thickness, and fullness of natural eyelashes. Eyelash extensions, however, must be applied to an individual's natural eyelashes one by one to avoid having the eyelash extensions stick together. Consequently, lash extension services can cost hundreds of dollars depending on the type and number of lashes used, the skill of the cosmetician, and the venue where the eyelash extensions are applied. It usually takes an experienced cosmetician one to two hours to attach a full set of eyelash extensions.\n\nClusters of artificial lashes have conventionally been used to enhance the length, thickness, and fullness of an individual's natural eyelashes. However, each cluster must be applied to the individual's eyelashes individually in order to avoid having the clusters of artificial lashes stick together and to ensure multiple clusters are evenly distributed across the width of the individual's lash line.\n\nAlternatively, false eyelashes may be applied directly to an individual's eyelid. False eyelashes come in strips (and thus may also be referred to as “strip lashes”) that can be trimmed to fit the width of the individual's eyelid. While a strip of false eyelashes can be applied in a single motion, false eyelashes are easily distinguishable from the individual's natural eyelashes and may be uncomfortable when worn for extended periods of time.",
