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.

The present invention provides a brush including a brush head (28) carrying bristle filaments (6), a brush neck and a handle stem, which are arranged one behind the other in the longitudinal direction of the brush, in which a bristle carrier (32) holding the bristle filaments (6) is formed from a hard component (16) and the handle stem is formed from a foamed plastic material (24). In a method according to the invention, a first plastic component (16) is injected into a first mold cavity (14) to form a bristle carrier (32) holding bristle filaments (6), the bristle carrier (32) is transferred to a further mold cavity (22) and, in a further molding cycle, a foaming plastic (24) is introduced into the further mold cavity (22), which foams in the further mold cavity (22).

A paint brush having a handle with an integrated hanger that is pivotably movable between a retracted position for stowing the hanger within a groove of the handle, and an extended position for extending the hanger outwardly from the groove to hang the paint brush on an object. When stowed in the retracted position the hanger may be flush with an outer surface of the handle to enhance the ergonomic design. The hanger and groove may be configured to enable ease of deployment of the hanger from the retracted to extended position simply with a one-handed operation. The portion of the handle having the groove may be made of a flexible material which may better secure the hanger in the groove when stowed and/or may facilitate installation of the hanger. The handle may include a grip portion having the flexible material which is over-molded onto a rigid head portion.

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.

An applicator for applying a cosmetic product to the eyelashes and/or eyebrows. The applicator includes a core extending along a longitudinal axis X, and one or more elongated strip having a top planar surface with a plurality of bristles extending therefrom. The one or more elongated strip is wrapped in a helical pattern around the longitudinal axis X of the core. Each of the plurality of bristles have a bristle latitudinal axis Y and one or more branches extending at a downward angle θ from the bristle latitudinal axis Y.

Disclosed is a method of manufacturing bamboo toothbrush and a toothbrush manufactured thereby. According to the method of manufacturing bamboo toothbrush of a detailed embodiment of the present invention and a toothbrush manufactured by the method, it is possible to improve strength, surface roughness, and moisture resistance of a bamboo and adjust the color of the bamboo using hot pressing. Further, since sanding and polishing and separate coating and drying are not performed, the process time is reduced, whereby the manufacturing cost can be reduced.
