A method (500) for manufacturing a brush head (10). The method includes the steps of providing a plurality of bristle tuft retention elements (52), and inserting a bristle tuft (21) into each of the bristle tuft retention elements; using a heat reflection device (200) to evenly apply heat to at least partially melt the bristle tuft proximal end and, optionally, the retention element, create proximal end head portion (26) to retain the bristle tuft in the retention element.

The method for manufacturing a makeup brush includes: molding a ferrule and welding bristles to the ferrule. The ferrule includes a ferrule inner end; a ferrule outer end; a ferrule body; an interior; and a well. The well has a well base parallel to the ferrule outer end. The well base has an inner side and an outer side. The step of welding the bristles includes the steps of disposing the bristles in contact with the outer side of the well base and exposing the inner side of the well base to welding.

A method for manufacturing a toothbrush having a bristle carrier made of a thermoplastic material with a front side and a rear side is provided. At least one recess formed as a blind hole in the bristle carrier extends from the front side in the bristle carrier, and holds at least one bristle. The at least one bristle is received in a receiving opening of a tool melted to form a thickening at its attachment-side end and inserted with its attachment-side end into the recess. The thermoplastic material is heated and, by pressing the tool against the front side of the bristle carrier, is deformed such that the thermoplastic material is displaced radially inwards into the recess, at least in the region of an edge surrounding the recess, for the form-fitting sealing of the thickening, in that a projection provided radially adjacent to the recess is pressed into the thermoplastic material.

The present invention is a makeup brush with a releasably connectable ferrule and handle, so that the ferrules and handles are interchangeable. The means for releasably connecting the ferrule and the handle may be, for examples, by friction fit or by the inclusion of sliding features, such as a notch and channel, such being additional methods for releasable connectivity beyond those already patented and/or developed by the inventor.

The present invention relates to a brush comprising a system for mechanically fixing tufts of fibers that does not requires metal elements.

The present invention also refers to a method for the production of brushes by means of the fixing system.

According to the inventions, the brush (10) comprises a support body (1) comprising a plurality of holes (2) or cavities, and a plurality of tufts of fibers (3), each tuft being constituted by a plurality of fibers substantially U-folded in their central portion, in which said tufts of fibers (3) are fixed to said support body (1) through a mechanical fixing system of tufts of fibers (3) according to which, in each of said holes (2) is inserted the U-folded end of one of said tufts of fibers (3) and an insert (4), presenting a shape partially complementary to that of the hole (2), said insert (4) being coupled to the support body (1) by means of a forced coupling; wherein said fixing system is implemented by a punching machine (15) to which said insert (4) is fed in the form of a continuous chain (6) or a continuous profile (7) which separates said inserts (4) from each other when they are inserted into said holes (2); said insert (4), said support body (1) and said tufts of fibers (3) being made of equal or different materials but compatible with each other for being recycled together.
