Eyelash extension system
View Patent ↗An eyelash extension system having a backbone and a plurality of eyelash extensions attached to the backbone. An adhesive is applied to an application surface of the backbone, and the adhesive is selected from the group of adhesives comprising latex adhesives, solvent-borne adhesives, pressure-sensitive adhesives (PSAs), and hot melt adhesives.
1. An eyelash extension system comprising:
a backbone having a backbone surface and a backbone strip with opposed first and second ends;
a plurality of eyelash extensions attached to the backbone and depending therefrom;
a closure having a closure surface facing the backbone surface and a closure strip, the closure surface being substantially free of eyelash extensions, the closure strip having opposed first and second ends, wherein the first end of the backbone strip is attached to the first end of the closure strip and the second end of the backbone strip is attached to the second end of the closure strip, the closure having a first state wherein at least a part of the closure surface is spaced from the backbone surface, and a second state wherein the part of the closure surface abuts the backbone surface, wherein the backbone surface and the closure surface are both concave in the first state, and the backbone surface is concave and the closure surface is convex in the second state.
2. The eyelash extension system of claim 1 , wherein the part of the closure surface abutting the backbone surface is attached to the backbone surface in the second state.
3. The eyelash extension system of claim 2 , comprising an adhesive applied to one or both of the backbone surface and the closure surface.
4. The eyelash extension system of claim 2 , wherein the part of the closure surface abutting the backbone surface is magnetically coupled to the backbone surface in the second state.
5. The eyelash extension system of claim 1 , comprising at least one rib extending from the backbone surface to the closure surface.
6. The eyelash extension system of claim 5 , comprising a plurality of ribs extending from the backbone surface to the closure surface.
7. The eyelash extension system of claim 6 , wherein the plurality of ribs contract as the closure moves between the first state and the second state.
8. The eyelash extension system of claim 6 , wherein the plurality of ribs fracture as the closure moves between the first state and the second state.
9. An eyelash extension system comprising:
a backbone;
a plurality of eyelash extensions attached to the backbone and depending therefrom; and
a plurality of projections depending from at least some of the eyelash extensions, the projections having a surface facing toward the extensions from which the projections depend to hold an eyelash between the surface and the extension.
10. The eyelash extension system of claim 9 , wherein the projections have a first state wherein the surface faces away from the extensions from which the projections depend, and a second state wherein the surface faces towards the extensions from which the projections depend.
11. The eyelash extension system of claim 10 , wherein the projections transition between the first state and the second state in response to heat.
12. An eyelash extension system comprising:
a backbone comprising a plurality of slits, each slit defined by a first surface portion and a second surface portion, the first surface portion and the second surface portion being spaced from each other in a first state and the first surface portion and the second surface portion abutting each other in a second state; and
a plurality of eyelash extensions attached to the backbone and depending therefrom.
13. The eyelash extension system of claim 12 , comprising a plurality of pivots, each pivot disposed between one of the first surface portions and one of the second surface portions.
14. The eyelash extension system of claim 13 , wherein the pivots comprise living hinges.
15. The eyelash extension system of claim 13 , wherein the plurality of hinges are integral to the backbone.
16. The eyelash extension system of claim 12 , wherein the backbone has a backbone surface in which the slits are formed, the backbone surface being concave in the second state and not concave in the first state.
17. The eyelash extension system of claim 13 , wherein the pivot is biased toward the second state.
