Abstract

A semi-permanent lash extension, applied in segments distributed laterally, includes individual filaments of preselected density, length, and curl radius bonded to or embedded into a substrate. Adhesive may be integral with the substrate, applied to it during or after manufacture, or in multiple layers to secure filaments to the substrates or the assembly to lashes of a wearer. Double-sided tape may do both. A semi-permanent lash extension, applied by a consumer, includes a pre-applied adhesive and provides for quick, easy application.

Claims (17)

1 . An artificial eyelash system, comprising:

an artificial eyelash segment, comprising:

a substrate having a length, a proximal end, and a distal end;

a plurality of fibers connected to the substrate along the length of the substrate, wherein each fiber extends approximately orthogonal to the substrate; and

a first adhesive proximate the substrate and along the length of the substrate, wherein the first adhesive is pre-applied to an upper side of the artificial eyelash segment; and

a second adhesive that is different from the first adhesive and configured to be applied to at least a portion of a user's natural eyelashes;

wherein the artificial eyelash segment is configured to be secured to at least a portion of the user's natural eyelashes at a location corresponding to the first adhesive and where the second adhesive is applied to the user's natural eyelashes,

wherein an application of the first adhesive with the second adhesive creates a bond that attaches the artificial eyelash segment to the user's natural eyelashes and allows relative movement between the user's natural eyelashes and the artificial eyelash segment at the location.

2 . The artificial eyelash system of claim 1 , wherein the first adhesive is a pressure-sensitive tape adhesive.

3 . The artificial eyelash system of claim 1 , further comprising a transverse fiber connected along the length of the substrate to support the plurality of fibers.

4 . The artificial eyelash system of claim 1 , further comprising a cover connected to the plurality of fibers and to the substrate, wherein the plurality of fibers is between the substrate and the cover.

5 . The artificial eyelash system of claim 2 , further comprising a backer removably attached to the pressure-sensitive tape adhesive.

6 . The artificial eyelash system of claim 1 , wherein the plurality of fibers decrease in length toward the distal end of the substrate.

7 . The artificial eyelash system of claim 4 , further comprising a backer removably attached to the first adhesive.

8 . The artificial eyelash system of claim 2 , further comprising a transverse fiber connected along the length of the substrate to support the plurality of fibers.

9 . The artificial eyelash system of claim 1 , wherein the substrate further comprises a fold that stabilizes at least a portion of the plurality of fibers in a lateral direction.

10 . The artificial eyelash system of claim 1 , wherein the first adhesive is a non-Newtonian adhesive.
