A powered toothbrush and toothbrush head comprise a transmission housing; a substantially disk-shaped bristle carrier; a plurality of first bristle tufts arranged on the bristle carrier along a first virtual circle; and a plurality of second bristle tufts arranged on the bristle carrier along a second virtual circle, the second virtual circle being concentric with and having a smaller diameter than the first virtual circle, wherein each of the plurality of first bristle tufts includes a plurality of bristles of a first type, having a tapered form.

A backcombing brush for backcombing hair includes an array of bristles 4. Each bristle extends from a base to a free end and two lengths of bristle are provided. Shorter bristles 4a and the bottom of longer bristles 4b carry out backcombing, whilst the longer bristles smooth hair, or untangle knots/tangles in the hair to reduce the level of backcombing. The long bristles have a relatively wide first portion 5, towards the base of the bristle, and a relatively narrow second portion 6, towards the free end of the bristle. The bristles are arranged such that bristles in one row neither extend between adjacent bristles in an adjacent row nor partially occlude the space between bristles in an adjacent row.

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 $\frac{1}{X}\times \frac{TCEA}{TSA}=Z$
and Z is in a range of 0.04 to 0.065.

Rotating dental systems and related guards and methods are disclosed. In some instances a guard may be configured to prevent material from building up on at least a portion of the dental system. The guard may be configured to prevent materials from being discharged from the dental system. In some embodiments, the guard may also be configured to direct the flow of material along a portion of the dental system. Some guards within the scope of this disclosure comprise bristles.

Brush for cosmetic products made of plastic material of the type apt to engage with an applicator rod including a central core having a substantially cylindrical shape carrying at the end a dome-shaped radiussed appendix and of the combination of various series of teeth mutually equidistant in a longitudinal direction, characterised in that the teeth have a grain-shaped section, which furthermore has two opposite edge lines in correspondence of the extreme points of the major axis.

An oral care implement includes a head portion. The head portion includes one or more tooth cleaning elements. The oral care implement includes a handle portion that may be coupled to the head portion. The handle portion includes a central body having a proximal portion. The proximal portion may be opposite the head portion. The handle portion may include a first appendage extending laterally outwards from a first side of the central body in a first direction and a second appendage extending laterally outwards from a second side of the central body in a second direction opposite to the first direction. The first and second appendages may be angled towards each other to form an obtuse angle therebetween (e.g., when in an unstressed state). The proximal portion of the central body may protrude from a bottom end of the first and second appendages.

An end-rounding device comprises a movable body comprising an abrasive surface; a gearing for transferring a movement from a motor to the movable body; a providing unit for providing a plurality of bristle filament ends to the abrasive surface, wherein the providing unit comprises a clamping unit for clamping a bunch of filaments, wherein the bunch comprises a multiple of filaments of a bristle tuft; wherein the abrasive surface has a diameter from 80 mm to 300 mm and comprises a concave curvature oriented in the direction of the clamping unit; and wherein the clamping unit is movably spaced from the abrasive surface at a distance. A method of smoothening bristle filament ends utilizes the end-rounding device.

The invention relates to a wound cleansing device comprising a number of strand-shaped cleansing elements, characterized in that the cleansing quotient R=(E*F)/l of at least some cleansing elements is 0.05 N/mm or larger, particularly 0.1 N/mm or larger, preferably 1 N/mm or larger, particularly preferably 10 N/mm or larger and smaller than 1000 N/mm, preferably less than 500 N/mm, in particular 100 N/mm or smaller, wherein E denotes the modulus of elasticity of the material of which the cleansing elements are made, F denotes the average cross-sectional area of the cleansing elements in a direction perpendicular to the strand axis, and l denotes the effective length of the cleansing elements.

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 L is in a range of 0.04 to 0.065.

A toilet brush 1 having an articulated connection 5 between brush head 4 and brush handle 3 has a targeted blocking or lock in one of the two possible pivoting directions of the articulated connection 5 formed as a rotatable joint 10. For this purpose, the rotatable joint 10 is formed by the two fork ends 32, 33 at the end of the brush handle 3 and an axis 11, whereby the fork ends 32, 33 permit pivoting towards the side 15, but lock towards the other side 16, because here the two fork ends 32, 33 are connected to each other via a locking shell 41 and prevent pivoting. This locked, articulated connection 5 permits on the one hand very intensive cleaning of the outlet of the toilet basin, because the brush head 4 is bent up when pushed through and can then also clean the upper area of the outlet pipe. In addition, when the toilet brush 1 is turned, this articulated connection 5 is locked simultaneously and can clean the rest of the toilet basin with the corresponding pressure and also the inner channel at the upper edge of the toilet basin, again with the curved brush head 4. This improved cleaning effect is further optimized by the fact that practically the entire brush head 4 especially with bristles 6, 7, 8 is made of flexible, hygienically flawless material.
