Example aspects of a brush assembly and a method for providing a brush assembly are disclosed. The brush assembly can comprise a plurality of elongate primary brush bristles, each of the primary brush bristles defining a star-shaped transverse cross section, each of the primary brush bristles defining five substantially parallel outer edges and five substantially parallel inner edges extending along a length of the primary brush bristle; and a ferrule attached to the plurality of primary brush bristles.

A dental appliance for removing material from the mouth of a user is disclosed. The appliance has a body with a plurality of bores extending through the body. A cleaning element is positioned in each of the bores. The cleaning elements are disposed to extend beyond the body and are moveably positioned in the bores.

A device for providing oral care includes at least one lumen fluidly coupled to a brush head. The lumen is adapted to suction fluid via an aperture disposed within the brush head. The brush head may be provided an oral cleaning fluid to facilitate cleaning of oral anatomy. The oral cleaning fluid may be provided within a cup provided within a containment assembly coupled to the oral care tool. Alternatively, or in addition, the cleaning fluid may be provided via fluid reservoir fluidly coupled to the oral care tool. The brush head comprises a bristles section and a foam section.

Example aspects of a method of providing a cosmetic brush for use in the application of cosmetics are disclosed. The method can comprise the steps of extruding a plurality of elongate brush bristles each having a triangular transverse cross section, such that each of said elongate brush bristles defines three substantially parallel edges along the length of each of said the bristles; and combining said plurality of said bristles to provide a brush head configured for the application of cosmetics.

Applicator for cosmetic product having an elongate general shape in a longitudinal direction, including a fixed part and a part movable in relation thereto. The movable part includes protrusions, at least one chain having a strand forming a succession of open loops, the chain extending substantially parallel to the longitudinal axis of the applicator. The fixed part includes at least two links, at least two of the open loops on each chain being passed through by a link of the fixed part. Thus, each chain of the movable part is fastened with at least one degree of freedom to the fixed part, enabling relative movement of the chain in relation to the fixed part longitudinally. This improves quality of the application of the product and gives the applicator a sensation of flexibility, even if the applicator is constituted by a rigid material. The applicator can be made by additive manufacturing.

A mold insert and an injection-molding machine including the mold insert. The mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided.

A bristle for an oral care implement and an oral care implement including a plurality of such bristles. The bristle may include a body extending along a longitudinal axis from a proximal end to a distal end, the body having tapered portion having a transverse cross-sectional profile with a perimeter defined by a first linear section and a second linear section that intersect to form a first apex, a third linear section and a fourth linear section that intersect to form a second apex, a first curved section extending between the first and third linear sections, and a second curved section extending between the second and fourth linear sections. The body may also include a cylindrical body portion such that the tapered portion extends from a top end of the cylindrical body portion. The bristle includes various edges and rounded contours for enhanced cleaning.

Toothbrush head for an electric toothbrush comprising a brush which comprises a bristled dome joined to an annular carrier, wherein the bristled dome comprises a supporting dome having a convex outer surface, and bristles which extend outwards from the convex outer surface, and wherein the bristled dome is a monolithic structure comprising fused bristles. The brush can be substantially hemi-spherical, and the head can comprise one or two such brushes.

An applicator for applying a cosmetic composition to the eyelashes or eyebrows including a core, at least one element attached to the core, each element including a central part fitted onto the core and at least one application member carried by the central part, this application member being hollow and comprising at least one cavity passing through it in one direction and having a closed or almost closed contour when viewed in this direction, and/or at least two adjacent application members forming at least one almost closed cavity between one another.

An applicator for a cosmetic product including a fixed portion having an elongated shape along a longitudinal axis defining a longitudinal direction. The fixed portion is hollow, so that it includes an elongated cavity, and it includes holes connecting the cavity and an exterior area. The applicator includes a movable portion in relation to the fixed portion, the movable portion including an elongated central core in the longitudinal direction and disposed in the cavity formed by the fixed portion. The movable portion includes protuberances, each protuberance passing through a hole of the fixed portion so that it protrudes outside of said fixed portion. The configuration of the protuberances and of the holes makes it possible to move at least longitudinally the movable portion in relation to the fixed portion. The applicator may be obtained by additive manufacturing.
