An oral care implement that includes a conical tuft of bristles. In one embodiment, the invention is an oral care implement that includes a handle and a head coupled to the handle, the head having a front surface. A plurality of tooth cleaning elements extend from the front surface of the head. The plurality of tooth cleaning elements include a conical tuft that has a continuous bristle wall having an inner surface defining a cavity, the cavity having a transverse cross-sectional area that increases with distance from the front surface of the head. The plurality of tooth cleaning elements may also include a central cleaning element located within the cavity. The conical tuft may terminate in an annular top surface that undulates in height relative to the head. The plurality of tooth cleaning elements may include arcuate cleaning elements arranged in a loop about the conical tuft.

An oral care implement having tooth cleaning elements and an elastomeric soft tissue cleanser. In one aspect, the oral care implement has a handle and a head (110) coupled to the handle, an elastomeric soft tissue cleanser having a plurality of protuberances (152) extending from a rear surface of the head (110), and a plurality of tooth cleaning elements (115) extending from a front surface of the head. The protuberances (152) of the elastomeric soft tissue cleanser collectively define a convex longitudinal side profile and comprise at least one convex transverse top profile. The plurality of tooth cleaning elements (115) collectively define a concave longitudinal side profile and comprise at least one concave transverse top profile.

The present invention relates to an applicator for applying a cosmetic, makeup or care product to the eyelashes and/or eyebrows, having an application member comprising a core that extends along a longitudinal axis, and spikes that are carried by the core and are arranged in groups of spikes within longitudinal rows, in which applicator the groups of spikes are preferably uniformly spaced along the longitudinal rows and each comprise at least two spikes, at least one longitudinal row of spikes being axially offset with respect to the consecutive longitudinal row, in such a way that at least one group of spikes of the offset row occupies the same axial position as a space free of spikes between two groups of spikes of the consecutive row.

The present invention discloses a deburring brush, comprising a pressing plate, jacking posts, copper sleeves, gaskets, guide posts, springs and bristle units. When the bristle units need replacement, it only needs to place the deburring brush on the ground and then press down edges of the front side of a top plate, so that all the bristle units will fall off against the suction force of strong magnets under the action of each jacking post. According to the present invention, it avoids being time consuming and labor intensive due to removing the bristle units one by one by using a screw driver or other similar devices while replacing the bristle units, and at the same time the replacing speed of bristles is greatly increased.

A cosmetic brush device utilizing a plurality of bristles mounted to a base holder. A first portion of the bristles are located adjacent the base holder and include a part having a narrow transverse dimension, a second part possessing a relatively wide transverse dimension, and an intermediate part positioned between the first and second parts possessing a transverse dimension of a value between the first and second parts. The bristles also extend outwardly to a second portion having a crest of curved configuration.

An oral care implement that includes a handle (120) and a head (100) with a front surface. A plurality of tooth cleaning elements extend from the front surface. In one embodiment the plurality of tooth cleaning elements include a conical tuft (130) that is formed by a wall of bristles. The tooth cleaning elements may also include first and/or second sets of peripheral tooth cleaning elements located adjacent to opposing lateral edges of the head. The peripheral tooth cleaning elements may include elastomeric sleeve portions (144, 154) and bristle tuft portions (145, 155). The elastomeric sleeve portions may be formed as a part of an integrally formed elastomeric component (170).

Systems, methods, and new file formats are provided for printing 3D microstructures. In some implementations, a new file format is provided that defines 3D objects by a wireframe model expressed as a collection of wires. Because wires and their parameters are defined within the new file format, objects may be processed more efficiently and quickly to support 3D rendering operations. Such methods may be used to print new articles, such as eyelashes, bushes, swabs and other novel items.

A mascara applicator that comprises a molded brush (adapted for grooming) to which is mounted a non-molded, fiber brush (adapted for loading product). The molded brush comprises relatively harder, relatively less flexible, injection molded bristles, while the non-molded brush comprises relatively softer, more flexible fiber bristles.

An cosmetic applicator comprising a brush portion of relatively soft, flexible injection molded bristles, and a comb portion of relatively hard, inflexible injection molded teeth, the comb portion being assembled to the brush portion after each portion is molded. In one preferred embodiment, the comb portion has two or more columns of teeth arranged parallel to each other, which makes for a more effective comb.

A rotating cosmetics brush includes a movable brush head mounted in a housing. A motion actuator is operative to move the brush head in a rotational motion, wherein the brush head rotates about a rotational axis and simultaneously moves in a non-oscillatory movement about another axis different than the rotational axis.
