Personal-care applicator and processes for manufacturing same
View Patent ↗A personal-care applicator comprises at least one stem having a proximal end including a handle and a distal end opposite to the proximal end and at least one bristled component attached to the stem, wherein the bristled component comprises a carrier and a plurality of bristles ultrasonically welded to the carrier and outwardly extending therefrom according to a pre-determined pattern, wherein the elongated carrier and the at least first plurality of 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.
1. A personal-care applicator comprising:
at least one stem having a proximal end including a handle and a distal end opposite to the proximal end, and
at least one bristled component attached to the stem, wherein the at least one bristled component comprises
a carrier having a longitudinal axis and a length, wherein the carrier has at least one longitudinal slot disposed along at least a portion of the length; and
at least a first plurality of bristles ultrasonically welded to the carrier and outwardly extending therefrom according to a first pre-determined pattern, wherein the elongated carrier and the at least first plurality of 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 personal-care applicator of claim 1 , wherein the at least one bristled component is attached to at least the first distal end of the stem.
3. The personal-care applicator of claim 2 , wherein the at least one bristled component is substantially parallel to the stem.
4. The personal-care applicator of claim 2 , wherein the at least one bristled component is angled relative to the stem.
5. The personal-care applicator of claim 1 , wherein the at least one bristled component is attached to the stem lengthwise between the proximal and distal ends of the stem.
6. The personal-care applicator of claim 5 , wherein the at least one bristled component is substantially parallel to the stem.
7. The personal-care applicator of claim 5 , wherein at least a portion of the bristled component has a shape of a substantially helical coil spiraling around the stem.
8. The personal-care applicator of claim 7 , wherein the bristled component and the stem are at least partially twisted around a longitudinal axis of the stem.
9. The personal-care applicator of claim 1 , wherein the at least one bristled component is slidably attached to the stem.
10. The personal-care applicator of claim 1 , wherein the at least one bristled component comprises a plurality of bristled components selected from the group consisting of a component for heavy-loading mascara application, a component for increased-volume mascara application, a component for lift-and-curl mascara application, a component for lash-separation mascara application, and any combination thereof.
11. The personal-care applicator of claim 10 , wherein the plurality of bristle components include bristled components removably attachable to the stem.
12. The personal-care applicator of claim 10 , wherein the plurality of bristled components and the stem are structured and configured to at least partially fold into the stem and to unfold from the stem.
13. The personal-care applicator of claim 1 , wherein the at least first plurality of bristles comprises at least a first array of bristles and a second array of bristles, and wherein the first array of bristles differs from the second array of bristles with respect to at least one physical parameter selected from the group consisting of material, length, thickness, shape, elasticity, stiffness, rigidity, color, angles of inclination, and pattern of distribution of bristles in the row, including density and distances between adjacent bristles.
14. The personal-care applicator of claim 1 , wherein the at least 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.
15. The personal-care applicator of claim 1 , wherein the at least first plurality of bristles comprises bristles that outwardly extend from the stem at angles comprising from about −45 degrees to about +45 degrees relative to the stem.
16. The personal-care applicator of claim 1 , wherein the at least first plurality of bristles comprises bristles that mutually intersect to form a crisscross pattern of the bristles.
17. The personal-care applicator of claim 1 , wherein the at least first plurality of bristles comprises bristles that form tufts of bristles.
18. The personal-care applicator of claim 1 , wherein the at least first plurality of bristles comprises bristles having cross-sectional configurations selected from the group consisting of round, rectangular, triangular, polygon, elliptical, solid, hollow, and irregular shapes, and any combination thereof.
19. The personal-care applicator of claim 1 , comprising two stems attached to the handle at both sides thereof so that the handle is disposed intermediate the distal ends of the two stems.
20. The personal-care applicator of claim 19 , wherein the two stems consist of a first stem and a second stem substantially parallel to the first stem, wherein the first stem has a first array of bristles attached thereto and the second stem has a second array of bristles attached thereto, and wherein the bristles of the first array differ from the bristles of the second array in at least one characteristic selected from the group consisting of pattern of distribution of the bristles on the stem, bristle material, length, thickness, shape, specific gravity, rigidity, stiffness, flexibility elasticity, color, and angle of inclination relative to the stem.
