| 015206000 | Twisted bristle holder | 8 |
| 20090139043 | Cleaning device with cleaning means and a frame body - The present invention relates to a cleaning device comprising cleaning means and a frame body. The frame body is provided with a plurality of connecting holes, wherein each connecting hole is constituted by a larger diameter hole and a smaller diameter hole, such that the twisted cleaning means is folded to stuff through the connecting holes from the larger diameter hole to the smaller diameter hole. The folded twisted cleaning means then is pulled back so as to bind the twisted cleaning means in the frame body. | 06-04-2009 |
| 20090276973 | Cosmetic Applicator Assembly - A cosmetic applicator assembly, which includes a polymeric brush and a twisted wire brush. Specifically, the polymeric brush comprises an elongated polymeric core and multiple polymeric tines protruding from the elongated polymeric core. The elongated polymeric core comprises a first polymeric material of a first tensile modulus, while at least some of the polymeric tines comprise a second polymeric material of a second tensile modulus that is smaller than the first tensile modulus. The twisted wire brush comprises a metal wire core and multiple bristles protruding from the metal wire core. The elongated polymeric core of the polymeric brush is complementarily engaged with at least a portion of the metal wire core of the twisted wire brush to form the cosmetic applicator assembly. The polymeric brush of the present invention is preferably formed by a bi-injection molding process. | 11-12-2009 |
| 20100192320 | HOMOGENEOUS CORE WIRE PROTECTIVE CLEANING TIP - A brush for use on sensitive surfaces comprising twisted a wire core having a handle end and a bristle end, a plurality of bristles extending radially outward from a portion of the wire core, the plurality of bristles defining a bristle block, and a protective tip integrally formed on the wire core at the bristle end for preventing the brush from damaging sensitive surfaces, wherein the wire core and the protective tip are formed from the same material. | 08-05-2010 |
| 20120240347 | APPARATUS AND METHOD FOR PRODUCING ROUND BRUSHES - An apparatus for producing round brushes, which have bristles twisted in between two portions of a folded wire. The apparatus has a bristle feeding device and a rotary gripper for twisting two portions of wire with bristles located therebetween, a deflecting device with two deflecting rollers spaced apart in the longitudinal direction of the wire. The rotary gripper is linearly displaceable transversely in relation to the longitudinal direction of the wire, for gripping the folded region of the wire that is formed by force being applied by an application element that is adjustable between the deflecting rollers transversely in relation to the longitudinal direction of the wire. A bristle feeding device, for feeding bristles to the bent-around portions of wire, is provided in the region of the deflecting rollers. In the region of the unfolded portions of wire there is provided a device for slowing the advancement of the wire. | 09-27-2012 |
| 20130232709 | METHOD FOR MOLDING SHAPE OF BRISTLES OF MASCARA BRUSH FOR EYELASHES, MOLD USED IN THE METHOD, AND MASCARA BRUSH MOLDED BY THE METHOD - The present invention relates to a method for molding a shape of bristles of a mascara brush for eyelashes, a mold in used in the method. Two strands of iron cores are twisted and brush bristles respectively having dorsal portions are radially spread between the twisted iron cores through post-process so as to form a mascara brush, wherein the dorsal portions are formed by the brush bristles of the same length on the basis of the iron cores without difference in the length of the brush bristles, so that a mascara solution contained in the dorsal portion does not run down when being applied to eyelashes, and the mascara provides more volume and a beautiful eyelash make-up when a sufficient amount of the mascara solution is applied. | 09-12-2013 |
| 20150033489 | TWISTED BRUSH WITH PARALLEL BRISTLES AT THE DISTAL END - A wire core brush composed of a core comprising at least two wires twisted together between which are held bristle-forming elements, which form bristles that protrude from the core, characterized in that the wire core brush has been produced in such a way that after the twisting, it has first bristles protruding from the core essentially in the radial direction with a first length and also has second bristles protruding from the core essentially in the radial direction with a second length that is greater than the first length so that the second bristles protrude beyond the first bristles essentially in the radial direction; after this, the brush has been pulled through a hot tube whose inner diameter and temperature are selected and matched to the residence time of the brush in the tube so that a section of the second bristles is permanently oriented essentially parallel to the longitudinal axis of the wire core. | 02-05-2015 |
| 20160128448 | METHOD FOR MOLDING SHAPE OF BRISTLES OF MASCARA BRUSH FOR EYELASHES, MOLD USED IN THE METHOD, AND MASCARA BRUSH MOLDED BY THE METHOD - A mascara brush for eyelash makeup includes two strands of iron cores and brush bristles having dorsal portions, which are formed by nylon bristles put on the iron cores and twisted spirally several times so as to be formed radially on the basis of the iron cores, the brush bristles having the dorsal portions having the same length on the basis of the iron cores. | 05-12-2016 |
| 20160128456 | BRUSH MANUFACTURING METHOD AND BRUSH - A plurality of bristle and core wire combination bodies each comprising a bristle of resilient wire formed into the shape of coil and a core wire of metal passed through the loops of the bristle are formed. The same number of other core wires of metal as the combination bodies are prepared. A core wire assembly is formed by twisting alternately the core wires of said combination bodies and the other core wires. A twisted wire body is formed by twisting the core wire assembly continuously in the longitudinal direction, in which a large number of loops of the bristles are arranged in a spiral shape in the longitudinal direction along the twist of the core wires. A plurality of rows of spiral brush bristles are formed by cutting the loops of the bristles of the twisted wire body. | 05-12-2016 |
