Cosmetics applicator
A cosmetics applicator includes a housing including a movable brush head, and a motion actuator operative to move the brush head in a vibrational motion, a rotational motion or a combination thereof. A cartridge contains a cosmetic to be dispensed. A dispensing actuator is operative to dispense the cosmetic out of the cartridge. The cartridge includes an applicator probe that extends forward to a center of the brush head and the cosmetic is dispensed out of a distal tip of the probe.
1. A cosmetics applicator comprising:
a housing comprising a movable brush head;
a motion actuator operative to move said brush head in a combination of vibrational motion and rotational motion;
a cartridge containing a cosmetic to be dispensed; and
a dispensing actuator operative to dispense the cosmetic out of said cartridge, wherein said cartridge comprises an applicator probe that extends forward to a center of said brush head and the cosmetic is dispensed out of a distal tip of said probe.
2. The cosmetics applicator according to claim 1 , wherein said cartridge is inserted at a rear opening of said housing.
3. The cosmetics applicator according to claim 1 , wherein said dispensing actuator is disposed in said housing.
4. The cosmetics applicator according to claim 1 , wherein said dispensing actuator is disposed in said cartridge.
5. The cosmetics applicator according to claim 1 , wherein said probe comprises a compressible nipple with a normally closed discharge opening at its distal tip, wherein said nipple serves as a one-way valve.
6. The cosmetics applicator according to claim 1 , further comprising a controller operatively connected to said motion actuator.
7. The cosmetics applicator according to claim 1 , further comprising a controller operatively connected to at least one of said motion actuator and said dispensing actuator.
8. The cosmetics applicator according to claim 1 , wherein said motion actuator is operative to move said brush head through a one-way gear system.
9. The cosmetics applicator according to claim 8 , wherein said one-way gear system comprises:
a planetary gear system comprising an outer gear, which has gear teeth on its outer contour for meshing with a spur gear rotated by said motion actuator;
a rotatable shaft that passes through a center of said outer gear and through a portion of said housing, said applicator probe passing through said rotatable shaft, wherein one end of said rotatable shaft is connected to said brush head and a rigid arm is mounted on an opposite end of said rotatable shaft, said rigid arm being formed with a channel;
a hub platform connected to said rotatable shaft by means of a first one-way bearing, which permits said hub platform to rotate in one direction only;
a planetary gear mounted on a gear shaft, which is rotatingly mounted on said hub platform by means of a second one-way bearing, which permits said planetary gear to rotate in one direction only; and
an eccentric shaft that protrudes from said planetary gear and is constrained to travel in said channel;
wherein said eccentric shaft can oscillate in said channel as said outer gear rotates, which causes vibration of said brush head; or said hub platform can rotate together with said outer gear, with said planetary gear travelling together with said hub platform, which causes rotation of said brush head.
10. The cosmetics applicator according to claim 1 , wherein said brush head comprises bristles in a spiral pattern.
11. The cosmetics applicator according to claim 1 , wherein said brush head comprises bristles with tapered ends slanted towards a center of said brush head.
12. The cosmetics applicator according to claim 1 , wherein said brush head comprises bristles with tapered ends slanted away from a center of said brush head.
13. The cosmetics applicator according to claim 1 , wherein said brush head comprises bristles of different heights.
