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.

The present invention relates to a brush with fusion interlocking bristle strip and a method of manufacturing the same. The brush includes carrier strips and knotted bristle strips bonded together by ultrasonic welding and interlocking.

A brush roller and its manufacturing method and brush roller mold is provided, the brush roller is manufactured by foaming a gaseous pore filler, while solving the problem of using a solid pore filler foaming method to manufacture the brush roller. In addition, the brush roller of the present invention has a plurality of fluid channels communicating between any adjacent two, and the plurality of fluid channels respectively extend to the surface of the brush roller to form pores to improve the fluid permeability of the brush roller, and in the brush roller manufacturing method of the present invention, after the PVA emulsified solution is cured, the compressive stress under the condition of the predetermined compression ratio can be formed to meet the expected brush roller, and it can be used to brush the circuit substrate.

Embodiments described herein generally relate to a brush, a method of forming a brush, and a structure embodied in a machine readable medium used in a design process are provided. The brush includes a body and a channel configured to deliver a cleaning liquid through holes in the body. The method forms the brush using 3D printing. The structure provides details for making the brush. The disclosure herein allows a method of forming a brush that does not require the removal of active porogen.

A cosmetic applicator with a bristle carrier (9), which merges into a stem (12), by way of which the bristle carrier (9) is connected to a handle (13), or into a coupling portion (11) for connecting the bristle carrier (9) to such a stem (12), wherein the bristle carrier (9) carries a multiplicity of in each case single-piece bristles (1) of length (L) and is distinguished in that the bristles (1) consist of two halves (2, 3), which are axially symmetrical relative to one another and are displaced relative to one another, and connected in one piece to one another, along their axis of symmetry (4), wherein each of the halves (2, 3) forms a planar region (6) of the bristle (1), said planar region being located in the displacement plane (5).

In an example, a method includes identifying, by processing circuitry, a feature of less than a threshold size of an object to be generated in additive manufacturing. In some examples the method further includes determining, by processing circuitry, a first density of a print agent to be applied to build material when generating the identified feature of the object based on an intended flexibility of the feature of the object. The method may further include determining, by processing circuitry, a second density of print agent to be applied to build material when generating another feature of the object.

A method of manufacturing a paint brush head comprising a bundle of bristles comprising synthetic bristles and a ferrule, a paint brush head manufactured according to the method and a paint brush comprising a paint brush head, The method comprising gathering a number of bristles comprising synthetic bristles into a bundle of bristles such that the bristles are tangent to each other along their length, aligning the bristles of the bundle of bristles at a first end of the bristles obtaining a flush end surface of the bundle of bristles, arranging the first end of the bristles in the ferrule, applying a thermoplastic adhesive in the ferrule at the flush end surface, fusing the first ends of the bristles at the flush end surface together by heat into a jointed bundle of bristles, and fusing the thermoplastic adhesive in the ferrule by means of the laser to connect the thermoplastic adhesive to the jointed bundle of bristles and the ferrule.

An applicator for applying a cosmetic composition to the human body having a substantially cylindrical base body, and bristles with flock fibers arranged on and protruding from the base body and distributed over the periphery of the base body.

An application element and an applicator comprising pluralities of said application elements on a molded support is provided for applying a product such as a cosmetic, a medicinal or a care product. At least one application element of the applicator includes a base portion and at least one thin projection. The thin projection includes at least one surface and wherein the at least one outer surface flushes with at least a portion of an outer surface of the base portion.
