Brush with magnetic filaments
View Patent ↗A brush with magnetic filaments is described. The brush may be used, for example, as a brush for applying a cosmetic material. The filaments of the brush may, in one example, be made of a synthetic material infused with magnetic material.
1. A cosmetic brush for simultaneously applying a skincare product and magnetic therapy comprising:
a handle;
a magnet disposed in the handle;
a cosmetic applicator coupled to an end of the handle, the cosmetic applicator comprising:
a plurality of fibers comprising synthetic, elastomeric filaments including a polymer resin and a magnetic material;
wherein the magnetic material provides the fibers a magnetic character; and
a ferromagnetic metal plate coupled to the magnet interposed between the magnet and the plurality of fibers, the ferromagnetic metal plate distributing a magnetic flux evenly from the magnet into the plurality of fibers;
wherein the magnetic flux from the magnet supplements the magnetic character provided by the magnetic material of the plurality of fibers.
2. The cosmetic brush of claim 1 , wherein the synthetic, elastomeric filaments comprise greater than or equal to 80% but less than 100% of Polybutylene Terephthalate (PBT), and less than or equal to 20% of strontium ferrite by weight, and wherein the synthetic, elastomeric filaments comprise a diameter of between about 0.05 mm and about 0.25 mm.
3. The cosmetic brush of claim 1 , wherein the magnetic material comprises magnetic powder.
4. The cosmetic brush of claim 1 , wherein the magnetic material comprises magnetic granules.
5. The cosmetic brush of claim 1 , wherein the magnetic material comprises strontium ferrite, magnetite, and/or hematite.
6. The cosmetic brush of claim 1 , wherein the magnetic material comprises a permanent magnetic material.
7. The cosmetic brush of claim 1 , wherein the magnetic material comprises a ferrous material.
8. The cosmetic brush of claim 1 , wherein the synthetic, elastomeric filaments comprise taklon, nylon, Polybutylene Terephthalate (PBT), Polyethylene Terephthalate (PET), polyester and/or Polypropylene (PP).
9. A cosmetic brush for simultaneously applying a skincare product and magnetic therapy comprising:
a handle with a length dimension extending along a longitudinal axis, the length dimension being a greatest dimension of the cosmetic brush;
a cosmetic applicator coupled to an end of the handle extending in a direction substantially parallel to the longitudinal axis, the cosmetic applicator comprising:
a plurality of supple natural or synthetic fibers coated in or infused with a permanently magnetic material; and
a disk shaped permanent magnet disposed in the handle that distributes a magnetic flux into the plurality of fibers;
wherein the cosmetic applicator has a magnetic character comprising:
a first magnetic field provided by the permanently magnetic material; and
a second magnetic field, provided by the disk shaped permanent magnet, that supplements the first magnetic field.
10. The cosmetic brush of claim 9 , wherein the fibers comprise synthetic, elastomeric filaments infused with magnetic material.
11. The cosmetic brush of claim 9 , wherein the fibers comprise synthetic, elastomeric filaments, and wherein a composition of the synthetic, elastomeric filaments comprises greater than or equal to 80% but less than 100% of Polybutylene Terephthalate (PBT), and less than or equal to 20% of strontium ferrite by weight.
12. The cosmetic brush of claim 11 , wherein the synthetic, elastomeric filaments comprise a diameter of between about 0.05 mm and about 0.25 mm.
13. The cosmetic brush of claim 9 , further comprising a ferromagnetic plate disposed between the disk shaped permanent magnet and the plurality of supple natural or synthetic fibers to evenly distribute the magnetic flux of the disk shaped permanent magnet into the plurality of supple natural or synthetic fibers.
14. A cosmetic brush for simultaneously applying a skincare product and magnetic therapy comprising:
a handle with a length dimension extending along a longitudinal axis, the length dimension being a greatest dimension of the cosmetic brush;
a cosmetic applicator coupled to an end of the handle extending in a direction substantially parallel to the longitudinal axis, the cosmetic applicator comprising:
a plurality of supple natural fibers coated in or infused with a permanently magnetic material to provide the cosmetic brush a first magnetic field; and
a magnet disposed in the handle to provide the cosmetic brush a second magnetic field;
wherein the second magnetic field supplements the first magnetic field.
15. The cosmetic brush of claim 14 , wherein the magnet disposed in the handle is a permanent magnet.
16. The cosmetic brush of claim 14 , wherein the supple natural fibers comprise hair, cellulose fibers, cotton, hemp or flax.
17. The cosmetic brush of claim 14 , further comprising a ferromagnetic plate disposed between the magnet and the cosmetic applicator to evenly distribute the second magnetic field of the magnet onto the first magnetic field of the plurality of fibers.
