A cleaning element carrier for a toothbrush in a form of a disk has a back surface including a central depression covering at least 70% of the back surface and forming an edge at the border. The carrier's front surface includes at least one protrusion so that the front surface comprises two levels, wherein the area covered by the depression is larger than the area covered by the protrusion.

Cleaning element carrier and toothbrush head comprising it

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.

Toothbrush heads comprising a two-component cleaning element and method for producing the same

A carrier for providing at least one cleaning element to a mold cavity is disclosed. The carrier includes a main body having a first surface including one or more openings of one or more blind holes having a depth (D) for carrying the at least one cleaning element and a second surface being substantially parallel to the first surface. The main body includes at least two partial bodies which are arranged adjacent to each other in the direction of the one or more blind holes so that at least one partial body comprises one or more through-holes as part of the one or more blind holes and one partial body comprising the second surface of the main body comprises the blind end of the one or more blind-holes.

Carrier for cleaning elements and method for producing such carriers for use in the production of toothbrush heads

A brush head section for an oral care device is provided. The brush section includes an insert being made from a first thermoplastic material by injection-molding, at least one oral cleaning element and a cleaning element carrier consisting of a second thermoplastic material or a second thermoplastic mixture. The insert and the at least one cleaning element are partially embedded into the cleaning element carrier by over-molding and the cleaning element carrier at least partly engages behind the insert. The hardness of the second thermoplastic material is less than the hardness of the first thermoplastic material.
