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. The present invention also prevents afterspray by discharging the stored charge remaining in storage elements of the high voltage power supply.

Electrostatic spray device

An electrostatic spray device and a cartridge for an electrostatic spray device that reduce the occurrence of electrically induced emulsion product separation are disclosed. The device and/or the cartridge may reduce electrically induced emulsion product separation by providing a conductive high voltage shield substantially around the product reservoir. Alternatively, the device and/or the cartridge may prevent the product located at the charging location from being in fluid communication with the product reservoir so that the product that is being charged cannot flow back into the product reservoir. The device and/or cartridge may alternatively reduce electrically induced emulsion product separation by minimizing the volume of product between the charging location and the exit orifice of the nozzle.

An electrostatic spraying device being configured and disposed to electrostatically charge and dispense a product from a supply to a point of dispersal. This device has a reservoir configured to contain the supply of product and a nozzle to disperse the product. A channel is disposed between the reservoir and the nozzle, wherein the channel permits the electrostatic charging of the product upon the product moving within the channel. A positive displacement mechanism is used to move the product from the reservoir to the nozzle. A portion of the high voltage electrode being disposed between the reservoir and the nozzle is used to electrostatically charge the product within the channel at a charging location. A mixing mechanism may be disposed between the reservoir and the nozzle to reconstitute any product which may have separated. The high voltage contact may be spring biased in direction towards the high voltage electrode. The high voltage electrode may be annular to improve contact with the high voltage contact.

Disposable cartridge for electrostatic spray device

The present invention is an electrostatic spraying device to electrostatically charge and dispense a product from a reservoir to a point of dispersal that includes a nozzle having an exit orifice and being disposed at the point of dispersal to disperse the product. A channel is included that permits the electrostatic charging of product. A positive displacement mechanism is used to move the product from the reservoir to the nozzle. A power source supplies an electrical charge. A portion of a high voltage electrode being disposed between the reservoir and the nozzle is used to electrostatically charge product within the channel at a charging location. A distance between the charging location and the nozzle exit orifice is governed by V /d<100,000, wherein V &equals;an output voltage of said high voltage power supply and d&equals;linear distance between the charging location and said nozzle exit orifice.

The present invention relates to substantially uniform, discontinuous films of a skin care product having a defined average particle size, particle spacing and coverage value. The films provide improved skin appearance, e.g., good apparent coverage and a natural look. The films can be formed by any method which provides the defined particle size, particle spacing and coverage value, including silk screening and the like and electrostatic spray techniques. The films are preferably formed by electrostatically spraying the composition onto the skin.

Sprayer cartridge

Sprayer

An electrostatic spraying device which is designed to be portable, hand-held, self-contained and battery operated, with a disposable cartridge. The electrostatic spraying device is configured to provide a precise essentially constant flow rate of a product being applied, to provide uniformity and ease of application of the product, as well as to conserve product usage.

The present invention is for powder compositions containing high levels of talc, low levels of titanium dioxide and a sebum absorbing material wherein the composition has improved skin coverage, uniformity and duration of wear. The invention can be used in formulating numerous cosmetic powder compositions such as eye shadow, foundation, loose powder and the like.

Cosmetic powder compositions having improved skin coverage

The present invention is for powder compositions having high levels of talc and low levels of titanium dioxide wherein said compositions have improved skin coverage and uniformity. Said compositions comprise talc wherein said talc comprises a first talc having a particle size distribution wherein no more than about 45% of the particles are 10 microns or less; no more than about 70% of the particles are 15 microns or less and no more than about 75% of the particles are 20 microns or less and a second talc having a particle size distribution wherein no less than about 75% of the particles are 10 microns or less, no less than about 90% of the particles are 15 microns or less and no less than about 95% of the particles are 20 microns or less. The ratio of said first talc to said second talc is from about 1:1 to about 6:1. The invention can be used in formulating numerous cosmetic powder compositions such as eye shadow, foundation, loose powder and the like.

Green coffee beans are dried prior to roasting to a moisture content of from 0.5 to 7%. The drying is conducted at from 70.degree. to 325.degree. F. (21.degree. to 163.degree. C.) for from 1 minute to 24 hours. The dried green beans are fast roasted to a Hunter L-color of from 10-16. The dried roasted beans are blended with non-dried coffee beans roasted to a Hunter L-color of from 17-24 and having a moisture content before roasting of greater than about 7%. The blend contains from 1-50% of the dried dark roasted beans and from 50-99% of the non-dried roasted beans. The blend has a surprisingly high yield.

High-yield roasted coffee with balanced flavor

Roasted coffee granules are admixed with roasted coffee non-granules in critical weight ratios. The smaller coffee non-granules include flaked coffee, flaked coffee fines, ground coffee fines, and coffee agglomerates. The larger coffee granules include roast and ground coffee. The coffee granules and coffee non-granules are densified to between 0.41 to 0.56 grams/cc. The compact coffee has the flowability, flavor, aroma and strength of roast and ground coffee. At equal volumes, the compact coffee results in more brewed coffee than conventional roast and ground coffee.
