Technical Developments in Nail Coating Brushes

A new type of nail polish brush that prevents damage to the bristles during production and improves efficiency. The brush has a unique design with a removable fixed piece that attaches to the bristle end. This allows the bristles to be inserted into the brush head pores without getting caught or damaged during assembly. The fixed piece can be easily removed once the brush is complete. This prevents bristle damage during production while still providing a secure connection to the brush head.

Brush device for applying liquid, like nail polish, with a brush shaft that has improved elastic deflection behavior compared to conventional brushes. The shaft has stiffening ribs protruding radially outward from the outer surface. These ribs reduce elastic bending of the shaft during use, improving application precision. The ribs form fields delimited by sections without ribs. The shaft tapers and has a round or oval cross-section. It also has channels and a guide section.

A brush for applying cosmetic products like nail varnish that allows both right-handed and left-handed users to apply the product equally well by having an asymmetrical tuft of bristles. The brush handle is coupled at one end to a head with a tuft of bristles at the other end. The bristle tuft is shaped asymmetrically with respect to the brush handle axis. This allows the user to apply the product more naturally by holding the brush with the asymmetric tuft facing the nail instead of having to twist their hand to align the tuft parallel to the nail.

Interchangeable brush system for nail products like polish bottles that allows users to switch out the applicator brush for a different size, shape, style, composition, or color brush after purchase. The system involves a removable brush attached to the cap that can be swapped with another brush. This allows users to customize their brush for personal preference and application needs.

A brush for applying cosmetic products like nail varnish that allows applying the product to multiple nails with a single dip without smudging or wasting. The brush has a handle with a hole near the bristle end. The hole has at least one internal rib. The ribs couple with tufts of bristles. This configuration holds a reserve of product in the handle hole when dipping the brush. The ribs prevent the bristles from fully entering the hole, leaving some product in the hole. This allows applying the product to multiple nails with a single dip, without re-dipping.

A simple, low-cost nail polish brush that allows gradient nail painting without multiple brushes. The brush has a sponge body with an arched groove on one side that fits over a nail. The groove penetrates both sides of the sponge. By pressing harder or softer on the sponge, it applies more or less polish for gradient colors. The arched groove allows absorbing polish on both sides of the sponge. The handle detaches for replacing the sponge.

A replaceable brush nail polish applicator that allows easy brush replacement for nail artists. The applicator has a detachable brush head that can be easily swapped out when worn or damaged. The brush handle stays the same. This avoids the need to buy a whole new applicator when the brush wears out. The applicator also has a detachable lid to prevent contamination of the brush and storage area. The applicator has a unique hexagonal shape to prevent rolling. The brush head, handle, and lid all have matching hexagonal cross-sections. The brush head can be detached from the handle by removing the brush coupling portion. The lid attaches to the handle using a separate lid coupling portion. This allows independent replacement of the brush head and lid. The hexagonal shape prevents rolling when placed down during use. The hexagonal shape also has intaglio patterns to provide grip and prevent slipping.

Nail brush with two partially interpenetrating hair bunches to increase the amount of cosmetic substance taken each time the brush is dipped into a receptacle containing the substance. The brush also has longitudinal grooves along the handle that are equally spaced apart from the hair bunches at the base. This allows more substance to accumulate in the space defined by the handle and bunches. The grooves can be through the handle width for maximum substance retention.

Nail art brush design that enables uniform application of nail polish to avoid color unevenness when painting multiple nails at once. The brush has a handle and a curved or bent brush section with both long and short hair bundles. The long hair bundle is shorter than the short bundle but they both have the same width at the center. The shorter bundle curves or bends toward the long bundle at the center. This curved shape allows applying polish consistently across all nails without missing areas or overlapping.

A nail brush with a unique design that allows applying nail polish in one stroke and removing excess. The brush has a curved plate with bristles and a scraper on the bottom. The scraper is closer to the bristles than the end of the bristles. This configuration allows dipping the brush into the nail polish and then scraping off excess from the nail without needing to wipe it on the edge. The curved shape of the plate also helps apply the polish evenly.

A dual fan brush for applying nail polish and other cosmetics to nails with improved coverage and reduced drying issues. The brush has multiple fan-shaped hair bunches, each with increasing section size further from the handle. This allows more nail polish to be absorbed and distributed compared to a single fan brush. It prevents the need for multiple dips and applications, reducing drying variations and streaks.

A nail polish brush design and container with lighting to facilitate even application and manicure. The brush has flat unfolded bundles that spread widely on the nail to avoid thickness variations. The container has a light guide and lamp with a reflector and lens to illuminate the brush as it is applied to the nail. This allows visual confirmation of the brush position and spread for consistent coverage.

A nail polish brush with a unique brush head shape designed to evenly apply nail polish without multiple coats. The brush has a curved arc-shaped head with bristles that project outward. The curved head conforms to the shape of the nail, preventing application issues caused by a cylindrical brush. The bristles have a terminal at the center that protrudes outward and connects to a middle-of-arc fixed base. This arrangement distributes the bristles like a fan, allowing even coverage on the curved nail surface.

Nail brush with flexible hinged brush bodies that can easily adapt to the curved surfaces of nails and nail beds for more effective cleaning. The brush has three narrow rectangular brush bodies made of a flexible material connected by hinges. The hinged connection allows the brush bodies to pivot and fold, enabling the brush to conform to the concave shape of nails and nail beds without the need to adjust the angle. This provides better access and contact to remove dirt from areas like the back of the nail, hairline, and spaces between nails.

A nail polish applicator with multiple insertion grooves to improve nail polishing efficiency and prevent splitting. The applicator has separate insertion grooves in the handle instead of just one. This allows multiple brushes to be fixed into the grooves. The extra brushes enable wider coats to be applied faster without splitting. The brushes have curved shapes with varying radii to match nail edges. This helps evenly coat the nail bed and corners.

Nail polish applicator with a bent brush tip to prevent tearing and apply polish accurately when inserting into the nail. The applicator has a hollow rectangular metal piece with a brush attached at one end. The metal piece is folded and inserted into the nail bed to hold the brush in place. This prevents the brush from tearing the nail as it goes in. The bent brush tip ensures the nail polish is applied evenly when pressed against the nail. The metal piece has rounded corners at the front to prevent snagging.

A nail brush with a rotating structure to apply nail polish without damaging the brush or the nail polish formula. The brush has a rotating handle with a guide tube inside. The brush bristles are attached to the rotating handle. When the handle is rotated, the guide tube lifts the bristles from inside. This allows the bristles to be raised and lowered by rotating the handle. It prevents damage to the brush or nail polish formula by keeping the bristles elevated when not in use. The rotating mechanism allows the bristles to be easily raised and lowered for convenience.

Applicator for nail varnish and similar liquid compositions that prevents drying and clogging issues. The applicator has a reservoir, brush, passage, and suction mechanism. Nail varnish is drawn into the reservoir using the suction, applied to the nail with the brush, and then suctioned back to refresh the brush. This allows multiple nails to be coated without dipping the brush repeatedly. The applicator can also be attached to a nail varnish container for convenient usage.
