A toothbrush includes a head with a new design and a handle that operates to move the head. The toothbrush head has multiple types of purpose-designed bristle-bundles precisely mapped to target specifically all dental-gingival surfaces and anatomically niches, including various dead-corner niches/surfaces that are usually not accessible by currently existing toothbrushes. Each cluster of bristle-bundles contains bristles of different sizes, diameters, hardness, lengths, angulations and colors. The head is designed to be inclined to accommodate both lingual and palatal surfaces. This toothbrush head also functions uniquely by coupling over dental arches and rotating so that the brush does not need to be lifted during movement from one end to the other. Further, moving the handle with respect to the brush head causes the width of the brush head to change to accommodate the different widths of the teeth along the dental arch.

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.

A method for manufacturing an interdental cleaner includes providing a rod-shaped carrier made of plastic, into which laterally protruding bristles are embedded. In this case, a filament array formed of a plurality of filament strands is inserted into a holding cassette and is fixed in a predefined alignment in the holding cassette by means of a holding device. The holding cassette is then inserted into an injection-molding device and the filament array is extrusion-coated with plastic in the injection-molding device, forming a plurality of rod-shaped carriers arranged spaced apart next to one another. Finally, the filament strands forming the filament array are separated at least in the sections located between adjacent rod-shaped carriers. In addition, a device for carrying out the method is provided.

A bottle brush includes a handle and a brush head connected to the handle. The brush head has a longitudinal axis and further includes a barrel having a sidewall substantially parallel to the longitudinal axis. A first row of bristles extends from the sidewall at least in part transversely from the barrel to define a first bristle reach. At least two second rows of bristles extend from the sidewall at least in part transversely from the barrel to define a second bristle reach different from the first bristle reach. The at least two second rows of bristles may be spaced longitudinally from each other with the first row of bristles being longitudinally intermediate to the second rows of bristles.

Automatic toothbrushes are disclosed herein. A toothbrush configured in accordance with embodiments of the present technology can include, for example, a handle and a mouthguard coupled to the handle. The mouthguard can be configured to be positioned within a mouth of a user over multiple teeth of the user. A brush assembly having a plurality of bristles can be removably positioned within the mouthguard for engaging and cleaning the teeth of the user. A motor can be disposed within or coupled to the handle and configured to articulate the brush assembly within the mouthguard.

A cosmetic applicator that includes at least two twisted core brushes. At least one of the two twisted core brushes is curved in at least two planes. The at least two twisted core brushes are connected to each other at least at respective first ends thereof to form a loop.

Disclosed is a concept of a synthetic fiber substitute for pony hair, for use in cosmetic brushes or the like, made of PBT, with a mix of two diameters of fibers, 0.05 mm diameter and 0.07 mm diameter, with the ratio of the blend being 8:2 (8 parts 0.05 mm diameter and 2 parts 0.07 mm diameter). The tips used on both types of fibers is a “short tip”, and the wave characteristic of both types of fibers is “small wave”.
