Lash band for artificial lashes
An artificial eyelash extension unit includes a lash band supporting a plurality of artificial lashes. The lash band is an elongated member having a non-uniform property along its length. The property may include a cross-sectional dimension, composition, or a chemical or physical property such as modulus of elasticity or degree of cross-linking.
1 . A lash band for an artificial eyelash extension unit comprising:
an elongated base having an inner end, an outer end, and a length defined therebetween, the length extending along a longitudinal axis of the elongated base;
wherein the inner end of the elongated base is configured to be positioned proximate an inner corner of an eyeline;
wherein, at the inner end, the elongated base has a circular, rectangular, or elliptical cross-section, the circular, rectangular, or elliptical cross-section being taken along a first plane perpendicular to the longitudinal axis of the elongated base, the circular, rectangular, or elliptical cross-section at the inner end defining:
a first dimension,
a second dimension perpendicular to the first dimension, and
a first cross-sectional area based on the first and second dimensions;
wherein, at the outer end, the elongated base has a circular, rectangular, or elliptical cross-section being taken along a second plane perpendicular to the longitudinal axis of the elongated base, the circular, rectangular, or elliptical cross-section at the outer end defining:
a third dimension,
a fourth dimension perpendicular to the third dimension, and
a second cross-sectional area based on the third and fourth dimensions;
wherein the second plane is spaced in a parallel relation from the first plane;
wherein, at a third position between the inner end and the outer end, the elongated base has a circular, rectangular, or elliptical cross-section being taken along a third plane perpendicular to the longitudinal axis of the elongated base, the circular, rectangular, or elliptical cross-section at the third position defining:
a fifth dimension,
a sixth dimension perpendicular to the fifth dimension, and
a third cross-sectional area based on the fifth and sixth dimensions;
wherein the third plane is spaced in a parallel relation from the first plane and the second plane; and
wherein the third cross-sectional area is less than the first cross-sectional area and the third cross-sectional area is less than the second cross-sectional area.
2 . The lash band of claim 1 , wherein the elongated base comprises a non-uniform composition along the length thereof.
3 . The lash bad of claim 2 , wherein the non-uniform composition comprises a coating layer on a first portion of the elongated base, the coating layer being absent from a second portion of the elongated base.
4 . The lash band of claim 1 , wherein the cross-section at the inner end, the outer end, and/or the third position is circular.
5 . The lash band of claim 1 , wherein the cross-section at the inner end, the outer end, and/or the third position is rectangular.
6 . The lash band of claim 1 , wherein the cross-section at the inner end, the outer end, and/or the third position is elliptical.
7 . The lash band of claim 1 , wherein the length of the elongated base is approximately equal to a length of the eyeline.
8 . The lash band of claim 1 , wherein the elongated base is tapered from the inner end and/or the outer end to the third position.
9 . The lash band of claim 1 , wherein the elongated base has a stepped cross-sectional profile being taken along a fourth plane parallel to the longitudinal axis of the elongated base.
10 . An artificial eyelash extension unit comprising:
the lash band of claim 1 ; and
a plurality of artificial lashes attached to and extending from the lash band.
