Abstract
An application device for applying a cosmetic product includes a wand, and an applicator member on the wand. The applicator member includes a plurality of bristles configured to apply a cosmetic product. Some of bristles include a plurality of particles providing roughness on at least a portion of the outer surface of the bristles. The application device can be used in a cosmetic application system having a reservoir. The reservoir is configured to contain a cosmetic product capable of being applied with the application device.
Claims104
An application device for applying a cosmetic product, comprising:
- a wand;
- and
- an applicator member on said wand, the applicator member including a plurality of bristles configured to apply a cosmetic product other than toothpaste, wherein at least one bristle of the plurality of bristles includes a plurality of particles providing roughness on at least a portion of the outer surface of the at least one bristle, and wherein the at least one bristle is non-tapered.
An application device for applying a cosmetic product, comprising:
- a wand;
- and
- an applicator member on said wand, the applicator member including a plurality of bristles configured to apply a cosmetic product, wherein at least one bristle of the plurality of bristles includes a plurality of particles providing roughness on at least a portion of the outer surface of the at least one bristle,
- wherein some of the plurality of bristles lack the particles providing roughness.
A cosmetic application system comprising:
- an application device for applying a cosmetic product, comprising:
- a wand, and
- an applicator member on said wand, the applicator member including a plurality of bristles configured to apply a cosmetic product, wherein at least one bristle of the plurality of bristles includes a plurality of particles providing roughness on at least a portion of the outer surface of the at least one bristle;
- and
- a reservoir configured to contain a cosmetic product capable of being applied with the application device, wherein the reservoir includes an opening and a wiper configured to remove excess product from the applicator member when the applicator member is withdrawn from the reservoir.
A method of forming at least one non-tapered bristle having a plurality of particles providing roughness on at least a portion of the outer surface of the bristle, the method comprising:
- preparing a mixture of a thermoplastic material and a plurality of particles such that particles make up from about 0.2% to about 20% by volume of the total volume of the mixture;
- heating the mixture;
- extruding the mixture through a die to form a strand;
- cooling the strand at least once;
- raising the temperature of the strand to allow at least some of the particles to emerge at the surface of the strand;
- and
- cutting the strand to a desired length for the bristle,
- wherein the at least one bristle formed in the method is non-tapered.
A cosmetic application system comprising:
- an application device for applying a cosmetic product, comprising
- a wand, and
- an applicator member on said wand, the applicator member including a plurality of bristles configured to apply a cosmetic product, wherein at least one bristle of the plurality of bristles includes a plurality of particles providing roughness on at least a portion of the outer surface of the at least one bristle, and wherein the at least one bristle is non-tapered;
- and
- a reservoir configured to contain a cosmetic product capable of being applied with the application device.
An application device for applying a cosmetic product, comprising:
- a wand;
- and
- an applicator member on said wand, the applicator member including a plurality of bristles configured to apply a cosmetic product other than toothpaste, wherein at least one bristle of the plurality includes a plurality of particles providing roughness on at least a portion of the outer surface of the at least one bristle, and wherein the particles lack clay and lack silica.
An application device for applying a cosmetic product, comprising:
- a wand;
- and
- an applicator member on said wand, the applicator member including a plurality of bristles configured to apply a cosmetic product other than toothpaste, wherein at least one bristle of the plurality of bristles includes a plurality of particles providing roughness on at least a portion of the outer surface of the at least one bristle, and wherein the particles comprise a material chosen from one of mica, ZnO, TiO2, MgO, Al2O3, cotton, cellulose, talc, urea/formaldehyde, powdered wood, graphite, carbon, and mixtures thereof.
