Abstract

A bristled component for a cosmetic applicator comprising: an elongated carrier having a longitudinal axis; and at least a first plurality of bristles including at least one array of bristles ultrasonically welded to the carrier and outwardly extending therefrom according to a first pre-determined pattern, wherein the carrier and the bristles comprise ultrasonically compatible materials, and wherein the bristles are ultrasonically bonded to the carrier through a direct ultrasonic bond between a surface of the carrier and a lengthwise portion of each of the bristles.

First claim

We claim:

1. A bristled component for a personal-care applicator, the bristled component comprising:
at least one carrier having a longitudinal axis and a length, wherein the at least one carrier has at least one longitudinal slot disposed along at least a portion of the length of the carrier; and
at least a first plurality of bristles including at least one array of bristles ultrasonically welded to the carrier and outwardly extending therefrom according to a first pre-determined pattern, wherein the carrier and the bristles comprise ultrasonically compatible materials, and wherein the bristles are ultrasonically bonded to the carrier through a direct ultrasonic bond between at least one interior surface of the longitudinal slot of the carrier and a lengthwise portion of each of the bristles.

2. The bristled component of claim 1 , wherein the at least one carrier has a cross-sectional shape selected from the group consisting of round, rectangular, triangular, polygon, elliptical, substantially flat, solid, hollow, and irregular shapes, and any combination thereof.

3. The bristled component of claim 1 , wherein the bristles outwardly extend from the at least one carrier at an angle comprising from about −45 degrees to about +45 degrees relative to the longitudinal axis of the carrier.

4. The bristled component of claim 1 , wherein the bristles outwardly extend from the at least one carrier at various angles comprising from about −45 degrees to about +45 degrees relative to the longitudinal axis of the carrier.

5. The bristled component of claim 4 , wherein at least some of the bristles mutually intersect at a distance from a surface of the carrier to form a crisscross pattern of the bristles.

6. The bristled component of claim 1 , wherein at least some of the bristles are grouped together to form tufts of bristles.

7. The bristled component of claim 6 , wherein the first plurality of bristles comprises at least a first array of bristles and a second array of bristles, wherein the first array of bristles comprises a first plurality of tufts and the second array of bristles comprises a second plurality of tufts, and wherein the first plurality of tufts is offset relative to the second plurality of tufts.

8. The bristled component of claim 1 , wherein at least some bristles in the at least one array of bristles differ from one another in at least one physical characteristic selected from the group consisting of material, length, thickness, shape, specific gravity, rigidity, stiffness, flexibility elasticity, color, and angle of inclination relative to the carrier and angles of inclination of bristles relative to one another.

9. The bristled component of claim 1 , wherein the at least first plurality of bristles comprises a plurality of arrays of bristles extending from the carrier around its circumference.

10. The bristled component of claim 1 , wherein the at least first plurality of bristles comprises bristles having cross-sectional shapes selected from the group consisting round, rectangular, triangular, polygon, elliptical, solid, hollow, and irregular shapes, and any combination thereof.

11. The bristled component of claim 1 , wherein the at least one carrier comprises a plurality of carriers.

12. The bristled component of claim 1 , wherein the bristled component further comprises a core and wherein the at least one carrier is attached to the core.

13. The bristled component of claim 12 , wherein the core comprises an elongated element having a cross-sectional shape selected from the group comprising round, rectangular, triangular, polygon, elliptical, solid, hollow, and irregular shapes.

14. The bristled component of claim 1 , wherein the at least one longitudinal slot is generally V-shaped as viewed in a cross-section perpendicular to the longitudinal axis of the carrier, the at least one interior surface comprising a first interior surface and a second interior surface angled relative to the first interior surface, the first and second interior surfaces forming therebetween an angle from about 1 degree to about 179 degrees.

15. The bristled component of claim 14 , wherein the angle formed between the first and second interior surfaces is from about 5 degrees to about 90 degrees.

16. The bristled component of claim 14 , wherein the first interior surface is wider than the second interior surface.

17. The bristled component of claim 14 , wherein the at least one array of bristles comprises a first array of bristles and a second array of bristles, the first array of bristles being ultrasonically welded to the first interior surface of the longitudinal slot and the second array of bristles being ultrasonically welded to the second interior surface of the longitudinal slot, and wherein the lengthwise portions of the bristles forming the direct ultrasonic bonds with the first interior surface are substantially parallel to the first interior surface, and the lengthwise portions of the bristles forming the direct ultrasonic bonds with the second interior surface are substantially parallel to the second interior surface.

18. The bristled component of claim 14 , wherein the lengthwise portions of the bristles forming the direct ultrasonic bonds with the carrier are from about 0.1 mm to about 10 mm.
