Cosmetic applicator and method of making
View Patent ↗A method of manufacturing a cosmetic applicator formed of a substrate and an application element comprising one or more application areas that are cohesively maintained on the substrate in a gapless, side-by-side formation in the presence of wet and/or dry binders. The substrate is subjected to a wetting agent that provides a better bind for the cosmetic slurries as they are printed onto their respective application area. The cosmetic compositions of each cosmetic application area may be different. Various cosmetic effects may be provided to end-users in a portable application.
1. A method for making a cosmetic applicator, comprising the steps of:
providing a flexible paper consisting of a cellulosic material;
screen printing a water miscible wetting agent directly onto the flexible paper to form a pre-wetted surface such that said wetting agent is absorbed into the flexible paper, and said wetting agent comprising a polyol having from 2 to 8 carbons and an agent to increase the viscosity of the wetting agent;
providing a first cosmetic slurry in a first pattern on the pre-wetted cellulosic material surface;
providing a second cosmetic slurry in a second pattern on the pre-wetted material surface, wherein the second pattern is adjacent the first pattern;
wherein the steps comprise:
allowing at least part of the wetting agent to become absorbed by the flexible paper;
subsequently, screen printing the first cosmetic slurry in the first pattern to form a screen printed first cosmetic;
evaporating at least part of the screen printed first cosmetic;
subsequently, screen printing the second cosmetic slurry in the second pattern to form a screen printed second cosmetic;
evaporating at least part of the screen printed second cosmetic; and
providing a protective layer over the screen printed first and second cosmetics.
2. The method of claim 1 , further comprising the step of subjecting the screen printed wetting agent to a temperature of about 60° F. to about 150° F. to evaporate at least part of the screen printed wetting agent.
3. The method of claim 1 , wherein the wetting agent is volatile.
4. The method of claim 1 , wherein the wetting agent is hydrophilic.
5. The method of claim 1 , wherein the wetting agent consists essentially of about 50.5% dipropylene glycol, about 44.5% propylene glycol, about 2.7% silica and about 2.3% varnish.
6. The method of claim 1 , wherein the first cosmetic slurry is different from the second cosmetic slurry.
7. The method of claim 1 , wherein the first pattern is in a side-by-side configuration with the second pattern, and wherein a side edge of the first pattern contacts a side edge of the second pattern.
8. The method of claim 1 , further comprising the step of sequentially providing a plurality of cosmetic slurries in a plurality of patterns on the pre-wetted material surface.
9. The method of claim 1 , further comprising the step of simultaneously providing a plurality of cosmetic slurries in a predefined pattern on the pre-wetted material surface.
10. The method of claim 1 , wherein the flexible paper has a thickness of about 0.0010 to about 0.0120 inches.
11. The method of claim 1 , wherein the flexible paper comprises paper provided on a carrier board.
12. The method of claim 11 , wherein the flexible paper has a thickness of about 0.0010 to about 0.0040 inches.
13. A method of manufacturing a disposable cosmetic applicator for applying a cosmetics preparation to an area between the human eyelid and the eyebrow, comprising the steps of:
providing a supporting paper surface consisting of a cellulosic material having a shape about similar to the shape of an area between the human eyelid and the eyebrow;
providing a water miscible wetting agent comprising at least one volatile material and at least one non-volatile material; said wetting agent comprising a polyol having from 2 to 8 carbons and an agent to increase the viscosity of the wetting agent;
employing a screen to print the wetting agent directly onto the supporting paper surface such that said wetting agent is absorbed into the supporting paper surface;
subjecting the screen printed wetting agent to drying conditions to evaporate at least part of the volatile material;
printing a plurality of cosmetic compositions on the supporting paper surface in a pre-determined pattern, so that at least one of the plurality of cosmetic compositions is provided in contact with, and in a side-by-side configuration, with another of the plurality of cosmetic compositions;
subjecting the plurality of printed cosmetic compositions to drying conditions to evaporate the remaining part of the volatile material; and
providing a protective layer over the plurality of printed cosmetic compositions.
14. The method of claim 13 , wherein the wetting agent is hydrophilic.
15. The method of claim 13 , wherein the wetting agent comprises two low molecular weight polyols.
16. The method of claim 13 , wherein the wetting agent comprises dipropylene glycol, propylene glycol, silica and varnish.
17. The method of claim 13 , wherein the supporting paper surface comprises a thickness of about 0.0010 to about 0.0120 inches.
18. The method of claim 13 , wherein the cosmetic compositions are in the form of a slurry or a powder.
