A bristle is provided. A first end of the bristle serves as a free end, and a second end of the bristle serves as a root. A cross section of the bristle is in a closed shape defined by at least two lines. Each of the lines is straight or curved. The bristle is twisted along a circumferential direction of its own axis. A mascara brush includes a core and at least one bristle. A root of the bristle is provided on the core, and a free end of the bristle is provided away from the core. A single row of bristles are spaced apart along an axis of the core, or multiple rows of bristles are spaced apart along the axis of the core and arranged radially along a circumferential direction of the core.

An oral care implement having a head with a bristle bearing surface. The oral care implement may include a central bristle tuft extending from a central portion of the bristle bearing surface, the central bristle tuft terminating in a domed distal surface. Furthermore, the oral care implement may include a plurality of perimetric bristle tufts extending from the bristle bearing surface and arranged to circumferentially surround the central bristle tuft. Each of the perimetric bristle tufts may have an inclined distal surface that slopes downward towards the central bristle tuft. The bristle bearing surface of the head may have a total surface area (TSA), and the toothbrush may include a tooth cleaning element field having X number of tooth cleaning elements that collectively occupy a total cleaning element area (TCEA) such that

[00001]$\frac{1}{X}\times \frac{TCEA}{TSA}=Z$

and Z is in a range of 0.04 to 0.065.

A cleaning brush for cleaning containers of complex design, wherein the cleaning brush can reach hard-to-reach areas of the container. The cleaning brush includes a twisted wire and a cleaning head coupled to the twisted wire. Portions of the twisted wire and the cleaning head have bristles. The cleaning head can flex sidewards relative to the twisted wire.

A dental hygiene device for brushing proximal surfaces of adjoining teeth and pockets resulting from crooked teeth includes a shaft, which has a first end and a second end. The first end is attachable to an electric toothbrush so that the shaft is operationally engaged thereto. The shaft is oscillated by the electric toothbrush. A plurality of bristles is engaged to and extends from the shaft proximate to the second end. The bristles oscillate coincidentally with the shaft. The plurality of bristles is tapered distal from the shaft so that the plurality of bristles is pointed. The plurality of bristles is used to brush proximal surfaces of adjoining teeth and pockets resulting from crooked teeth.

The present invention relates to a brush (10) for applying a product (P) to the eyelashes and/or eyebrows, comprising: a core (40) that extends along a longitudinal axis X, and bristles (41) that extend from the core (40) along a portion of length L.sub.2, the ends of the bristles (41) defining an envelope surface, the envelope surface having at least one longitudinally extending cutout, the cutout having: a length L.sub.2 where L.sub.2≥L.sub.1/2, a width w, measured at the bottom of the cutout, that is constant along at least a portion of its length L.sub.2, and a distance d from the longitudinal axis X that varies along its length L.sub.2.

A brush head for an electric toothbrush includes a support part supporting upper and lower lateral brush elements and transverse brush elements for the combined brushing of the inner, outer and occlusal surfaces of the upper and lower teeth, and an oscillating device intended to impart an oscillating movement to the support part. The support part is elastically deformable such that it can fit snugly against the upper and lower dental arches during brushing. The oscillating device includes a movable part on which the support part is mounted, and a drive shaft coupled to the movable part in order to move the movable part and the support part in an oscillating manner. The movable part extends between the upper lateral brush elements and the lower lateral brush elements.

A head for an oral care implement comprises a mounting surface and at least one tuft extending from the mounting surface. The tuft comprises a first group of filaments and at least a second group of filaments. The first group of filaments is surrounded by the second group of filaments. The filaments of the first group have a first length and the filaments of the second group have a second length, the first length being different from the second length. The difference in length between the first length and the second length is about 1.1 mm to about 1.9 mm.

A shed hair collection device includes a substantially planar mat and a gel pad. The mat has multiple substantially cylindrical protuberances with multiple nubs extending therefrom. A gel pad has multiple apertures attached to the mat such that each of the protuberances extends through one of the apertures. A shed hair collection device includes a hairbrush and a gel screen removably attached thereto. The hairbrush has a head with bristles and a handle. The gel screen has multiple apertures encircling the bristles. A shed hair collection device includes a silicone gel pad with multiple apertures and at least one loop formed at the perimeter. The silicone gel pad installs on a hairbrush head with bristles extending through the apertures.

Some embodiments of the present invention provide a novel, twisted-in-wire type interproximal brush equipped with yarn strands. According to some embodiments, the yarn strands may be formed of nylon filament having compression memory characteristics.

A pet hair removal apparatus has a plurality of engagement members. The apparatus has a handle and connected base member. On the base member is one or more engagement members, such as lugs, protrusions or frustums. On the lower surface of one of the engagement members is one or more striations, ribs, squeegees or ridges. The striations, ribs, squeegees or ridges operate in an operational engagement position to remove pet hair from the surface of an inanimate object, such as a couch or other fabric. This operational engagement position for the striations, ribs, squeegees or ridges is one of a number of other operational engagement positions for the pet hair removal apparatus.
