A method for manufacturing a brushing part including the following steps: providing the support, pierced with through-holes, passing through the channel formed by the support; forming the tuft of bristles, by assembling a plurality of bristles by one end opposite the free end, so as to form a base of the tuft, so that a diameter of a section of the tuft, in a plane transverse to a direction of extension of the tuft, is greater than a diameter of a through-hole; merging the ends forming the base of the at least one tuft so that an extension of the merged zone in a direction transverse to the direction of extension of the at least one tuft is greater than an extension of the base in the transverse direction before the merging step; inserting the one tuft by force into one of the holes of the channel of the support, depositing glue and filling with resin.

An oral care implement comprises a head and a handle, the head being repeatedly attachable to and detachable from the handle. The head is at least partially made from a material having a density from about 0.5 g/cm.sup.3 to about 1.2 g/cm.sup.3, while the handle is at least partially made from a material having a density from about 2.1 g/cm.sup.3 to about 3.1 g/cm.sup.3.

The invention relates to an oral care instrument, in particular a toothbrush or a tongue cleaner, including at least one cleaning element made from a first plastic component, wherein the first plastic component contains a thermoplastic elastomer and activated carbon. The invention also relates to a method for producing an oral care instrument, in particular a toothbrush or a tongue cleaner, including the following steps: a) providing a first plastic component by adding activated carbon to a thermoplastic elastomer, and b) producing a cleaning element from the first plastic component using an injection molding method.

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.

The present invention, a cylindrical rotary tire brush element with an integrated wear indicator, is intended to replace the prior art cylindrical rotary tire brush element in a prior art rotary tire brush assembly. The cylindrical rotary tire brush element with integrated wear indicator is intended as a drop-in replacement to the prior art cylindrical rotary tire brush element of a prior art rotary tire brush assembly. The invention is made from at least two homogeneous pluralities of bristles, with each homogeneous plurality of bristles having the same purpose, material, color, and specified length. At least one plurality is a cleaning bristle of a first color and first specified length. At least one plurality is an indicator bristle of a second color and a third specified length, where the second color is a highly noticeable color such as yellow, red, orange, green, or white. The third specified length is equal to the minimum acceptable actual length of the cleaning bristles.

A toothbrush head, including at least one two-component cleaning element and at least one bristle tuft element, is produced by injection molding. To achieve high design flexibility regarding the arrangement of the two-component cleaning elements and regarding the material choice, the two-component cleaning elements are manufactured separately or in an upstream molding step. Then the two-component cleaning elements, together with the bristle tufts, are over-molded with plastic material, to form the brush head or a part thereof.

A method of manufacturing a brush includes providing a core wire section having a proximal end and a distal end, and an integral tip on the distal end, forming a bristle element having a throughbore, and inserting the core wire section into the throughbore until the bristle element is received on the core wire section.
