Assembly technology for any shape disk brush
A cosmetic applicator brush including a plurality of discs assembled relative to one another with each disc having a body with a plurality of bristles and/or combs extending radially therefrom. The adjacent discs are maintained at an angular relationship with respect to one another independent of a disc specific keying element.
1. A cosmetic applicator brush comprising:
a plurality of discs assembled relative to one another, the assembled discs forming a group, each disc having a body with a plurality of bristles and/or combs extending radially therefrom,
wherein each disc body has wire passages extending therethrough and wire extends through the passages of the group of the plurality of discs to link the discs together and an amount of twist in the wire defines the angular relationship between adjacent discs,
wherein the plurality of discs are linked, and the wire is twisted independently at both ends of the cosmetic applicator brush to form a desired shape,
wherein the plurality of discs are made of plastic or rubber, and
wherein the wire is made of metal or metallic materials.
2. The cosmetic applicator brush according to claim 1 wherein each disc body has a first face with a projection extending therefrom and an opposed second face with an indentation defined therein, wherein the projection and indentation are angularly offset from one another and the interaction of a projection of one disc with the indentation of an adjacent disc maintains the angular relationship between the adjacent discs.
3. The cosmetic applicator brush according to claim 2 wherein angular offset of the projection and the indentation of each disc is between 0° and 360°.
4. The cosmetic applicator brush according to claim 3 wherein the angular offset is the same for each of the discs.
5. The cosmetic applicator brush according to claim 3 wherein the angular offset is different for at least two of the discs.
6. The cosmetic applicator brush according to claim 2 wherein the interaction of the projection of one disc with the indentation of an adjacent disc maintains the adjacent discs interconnected to form the brush head.
7. The cosmetic applicator brush according to claim 6 wherein the discs are further secured to one another via welding and/or gluing.
8. The cosmetic applicator brush according to claim 1 wherein each of the discs has a through bore and a rod extends through the through bore of each of the discs, and wherein the rod and through bore are free of any keying elements.
9. The cosmetic applicator brush according to claim 8 wherein the through bores and the rod each have a circular configuration.
10. The cosmetic applicator brush according to claim 8 wherein the rod defines a cap end with a finished surface and a connecting surface opposite thereto, the connecting surface defining a projection or a recess configured to engage a recess or projection on a face of an adjacent disc.
11. The cosmetic applicator brush according to claim 1 wherein the bristles on adjacent discs define a twisted bristle path.
12. The cosmetic applicator brush according to claim 1 wherein the combs on adjacent discs define a straight comb path.
13. The cosmetic applicator brush according to claim 1 wherein at least one bristle includes a main portion and at least one secondary portion extending from the main portion.
14. The cosmetic applicator brush according to claim 1 wherein each disc has a body and the bristles are defined by cutting away portions of the body.
15. The cosmetic applicator brush according to claim 14 wherein the disc body varies in thickness from a central portion thereof to a circumferential portion thereof.
16. The cosmetic applicator brush according to claim 14 wherein the disc body varies in thickness from a central portion thereof to a circumferential portion thereof in a wavy pattern.
17. The cosmetic applicator brush according to claim 14 wherein the disc body includes a plurality of bumps and/or recesses defined thereon.
