Abstract: An electrostatic spraying device has a removable cartridge with a reservoir containing a volume of liquid compositions to be electrically sprayed. The device includes a nozzle for dispensing the liquid and an emitter electrode disposed adjacent to the nozzle for charging the liquid composition just being dispensed from the nozzle. A field electrode surrounds the reservoir in order to charge the liquid composition within the reservoir, thereby avoiding an occurrence of electric current which would deteriorate the composition remaining in the reservoir. The reservoir is at least partially made of deformable material such that the reservoir is capable of receiving pressure to deform and thus supply the liquid composition out of the reservoir. Thus, the reservoir can be designed into a simple and compact structure, thereby providing an increased liquid containing volume in relation to the bulk of the removable cartridge.

Abstract: An electrostatic spraying device has a capability of confirming that the device is ready for making an electrostatic spraying of the liquid composition on a user's skin. The device includes a nozzle and a pump for dispensing the liquid composition out through the nozzle. An emitter electrode is disposed to electrostatically charge the liquid composition being dispensed for making the electrostatic spraying. The device is provided with a power switch and a selector for selection between a spraying mode and a dripping mode. In the dripping mode, the pump is alone actuated to dispense the liquid composition absent electrostatic charge. In the spraying mode, both of the pump and the emitter electrode are activated to make the electrostatic spraying. Thus, the user can be easy to drip the liquid composition by simply manipulating the selector prior to initiating the electrostatic spraying.

Abstract: An electrostatic spraying device having a removable cartridge with a reservoir containing a volume of liquid compositions to be electrically sprayed on a user's skin. The device includes a nozzle for dispensing the liquid as well as an emitter electrode disposed adjacent to the nozzle for charging the liquid composition just being dispensed from the nozzle. A field electrode surrounds the reservoir in order to charge the liquid composition within the reservoir, thereby avoiding an occurrence of electric current which would otherwise flow in the liquid composition and would deteriorate the composition remaining in the reservoir. The reservoir is devoid of the field electrode, and therefor can be designed into a simple and compact structure without being restricted by the field electrode, assuring to have an enhanced liquid containing volume in relation to the bulk of the removable cartridge.

Abstract: An apparatus for applying a cosmetic, such as mascara to eyelashes, includes a handle, a stem, and an applicator head coupled to the stem and supported for rotation relative to the handle. An actuator moves the applicator head in a rotational oscillating motion, in which the applicator head automatically rotates in both a first rotational direction and a second rotational direction in response to operation of the actuator. Additionally or alternatively, the actuator may also radially translate the applicator head, move the applicator head through an angle of rotation less than 360 degrees, and vary the rotational speed of the applicator head. The applicator head may include protrusions that are spaced to define gaps during rotation, thereby to promote coverage and separation of eyelashes.

Abstract: An apparatus for modifying a keratinous surface that has a rotatable applicator that is in fluid communication with a first modification composition. The apparatus also has a sensor and a CPU. The sensor is positioned forward of the applicator head such that as the head rolls across the keratinous surface the sensor reads the portion of the keratinous surface in front of the rolling head. The sensor readings are transmitted to the CPU, the CPU analyzes the sensor readings of the keratinous surface, and the CPU sends a signal to the applicator head to treat or not to treat the analyzed surface. When the CPU sends a signal to the applicator to treat the surface, a small portion of the first modification composition is applied to the head such that when the head rolls over the keratinous surface the first modification composition contacts the area of the keratinous surface that needs treatment.

If the CPU sends a signal to the applicator to treat the surface, the motor is activated to move the applicator to the keratinous surface such that the ribbon contacts the keratinous surface near the protrusion to apply a portion of the first modification composition to the keratinous surface that was read by the sensor.

The applicator also includes a sensor and a CPU. The sensor reads the properties of a small portion of the keratinous surface, the readings are transmitted to the CPU, the CPU analyzes the sensor reading of the keratinous surface. The CPU sends a signal to the applicator to treat or not to treat the analyzed surface, and if the CPU sends a signal to the applicator to treat the surface, the motor is activated to move the stylus to the keratinous surface to apply a portion of the first modification composition to the same portion of the keratinous surface that was read by the sensor.

Abstract: An apparatus for modifying a keratinous surface having an applicator, a first modification agent; a sensor; and a CPU. The sensor reads the properties of a small portion of the keratinous surface, the readings are transmitted to the CPU, and the CPU compares the readings to a predetermined baseline value. The CPU then calculates the variance between the reading and the baseline value. When that variance exceeds a predetermined threshold the CPU sends a signal to the applicator which is activated to apply a portion of the first modification composition to the same portion of the keratinous surface that had the reading with a variance above the threshold value.

Abstract: An electrostatic spray device that maintains a consistent charge-to-mass ratio in order to maintain a consistent target spray quality is disclosed. During steady state conditions, the high voltage power supply adjusts the output voltage level in response to changing environmental and/or operating conditions. During transient conditions such as start-up, shut-down and changing flow rate conditions, the high voltage power supply ensures that the charge-to-mass ratio is maintained. During, start-up, for example, the high voltage power supply charges the high voltage electrode to a predetermined voltage level before the product is delivered to the charging location. During shut-down, the product delivery is stopped before the high voltage power supply shuts off power to the high voltage electrode, and during changes in product flow rate, the voltage level of the high voltage electrode is adjusted to maintain a consistent charge-to-mass ratio.
