Abstract

An eyelash fan may include a plurality of hairs having a proximate end and a distal end. The plurality of hairs may be coupled together at a coupling region via an adhesive composition, heat fusion, or may be integrally formed. The coupling region is positioned at a distance from the proximate end such that the artificial hairs at the proximate end are not coupled or bound to each other. In this configuration, when the eyelash fan is applied to a single natural lash, the artificial hairs at the proximate end can wrap around the natural lash—thereby increasing the surface area and improving the wear time of the eyelash fan.

Claims (50)

1. An eyelash fan system comprising:

an eyelash fan comprising:

a plurality of artificial hairs having a proximate end and a distal end, the first plurality of artificial hairs defining:

a base region at the proximate end and having a first length ranging between 1 mm and 6 mm, the plurality of artificial hairs unbonded with respect to other each artificial hair prior to being installed, the plurality of artificial hairs at the proximate end are stacked to define an approximately circular cross-section;

a coupling region adjacent to the base region and having a second length that is a ratio from 1:1 to 1:4 of the first length, the coupling region including a first adhesive composition that is cured to bind the plurality of artificial hairs throughout the coupling region; and

a flared region adjacent to the coupling region and splaying outward from the coupling region, wherein:

the first length of the base region, the second length of the coupling region, and the circular cross-section are configured to cause the artificial hairs at the base region to wrap at least partially around a natural eyelash of a wearer when the eyelash fan is installed, and

a second adhesive composition applied to the base region prior to attachment of the eyelash fan to the natural eyelash of the wearer, wherein:

the plurality of artificial hairs of the eyelash fan are unbonded with respect to other eyelash fans of the eyelash fan system prior to being installed.

2. The eyelash fan system of claim 1 , wherein:

the eyelash fan is a first eyelash fan of a set of eyelash fans;

each eyelash fan of the set of eyelash fans are not attached to each other prior to being installed; and

each eyelash fan of the set of eyelash fans are configured to be attached to a respective upper natural lash of the wearer.

3. The eyelash fan system of claim 1 , wherein the plurality of artificial hairs includes 3 to 10 artificial hairs.

4. The eyelash fan system of claim 1 , wherein the eyelash fan is configured to be applied over the natural eyelash.

5. The eyelash fan system of claim 1 , wherein each artificial hair of the plurality of artificial hairs define a respective curvature with respect to the proximate end.

6. An eyelash fan configured to be applied to a single natural lash of a wearer's natural eyelashes, the eyelash fan comprising:

a plurality of artificial hairs defining a proximate end of the eyelash fan and a distal end of the eyelash fan, the plurality of artificial hairs defining a fanned region;

a base region at the proximate end and having a first length from 1 mm to 6 mm;

a coupling region positioned between the fanned region and the base region, the coupling region including a first adhesive that is cured to bind the plurality of artificial hairs together, the coupling region having a second length that is a ratio of 1:1 to 1:4 of the first length; and

a second adhesive composition applied to the base region prior to attachment of the eyelash fan to a natural eyelash of a wearer

wherein:

each artificial hair of the plurality of artificial hairs at the base region are unbonded with respect to each other artificial hair, the plurality of artificial hairs at the base region are stacked to define an approximately circular cross-section and are configured to at least partially wrap around the single natural lash.

7. The eyelash fan of claim 6 , wherein:

the eyelash fan is a first eyelash fan of a set of eyelash fans;

each eyelash fan of the set of eyelash fans are configured to be attached to a different natural lash of the wearer's natural eyelashes; and

two or more eyelash fans of the set of eyelash fans have a different length.

8. The eyelash fan of claim 6 , wherein:

the plurality of artificial hairs includes 3 to 10 artificial hairs; and

the coupling region comprises an adhesive composition extending longitudinally along the coupling region at a bonding length ranging between 1 and 5 mm.

9. The eyelash fan of claim 6 , wherein:

each artificial hair of the plurality of artificial hairs is between 0.03 mm and 0.07 mm in diameter; and

each artificial hair of the plurality of artificial hairs is formed from polybutylene terephthalate.

10. The eyelash fan of claim 6 , wherein the plurality of artificial hairs does not exceed 36 artificial hairs.

11. The eyelash fan of claim 6 , wherein the eyelash fan is a monolithic eyelash fan formed via a three-dimensional printing process.

12. The eyelash fan of claim 6 , wherein the plurality of artificial hairs are bonded at the coupling region via heat fusion.

13. An eyelash fan system comprising:

an eyelash fan comprising:

a plurality of artificial hairs having a proximate end and a distal end, the plurality of artificial hairs defining:

a base region starting at the proximate end and having a first length between 1 mm and 6 mm;

a coupling region extending from the base region and having a second length that is a ratio of 1:1 to 1:4 of the first length, the coupling region comprising a first adhesive composition binding the plurality of artificial hairs;

a second adhesive composition applied to the base region prior to attachment of the eyelash fan to a natural eyelash of a wearer; and

a flared region extending from the coupling region and widening toward the distal end, wherein:

the plurality of artificial hairs at the base region are arranged to define an approximately circular cross-section;

the plurality of artificial hairs at the base region are unbonded with respect to each other artificial hair by the first adhesive composition; and

the first length of the base region, the second length of the coupling region and the circular cross-section are configured to cause the artificial hairs at the base region to wrap at least partially around a natural eyelash of a wearer when the eyelash fan when installed.

14. The eyelash fan system of claim 13 , wherein the eyelash fan is configured to be positioned on one natural eyelash.

15. The eyelash fan system of claim 13 , wherein the first adhesive composition is cured prior to the eyelash fan being applied to the natural eyelash of the wearer.

16. The eyelash fan system of claim 13 , wherein the eyelash fan is configured to be applied under the natural eyelash.

17. The eyelash fan system of claim 13 , wherein each artificial hair of the plurality of artificial hairs defines a curvature.
