  • Patent number: 10687925
    Abstract: A brush head for an electric toothbrush comprises an attachable housing and a carrier having a mounting side and mounted for driven oscillatory rotational motion around a rotation axis that extends through a center point on the carrier's mounting side. Each of the tufts has a tufting area of at least about 2.0 mm2. Filaments in each of the tufts have a cross-sectional area perpendicular to their length extension direction that corresponds to a circular cross sectional area having a diameter in the range of between 140 ?m and 102 ?m, wherein the brush head comprises only tufts of the defined type.

  • Patent number: 10362858
    Abstract: A method of manufacturing a toothbrush includes steps of providing a carrier having at least a first through hole extending from a front side to a backside of the carrier and at least a first wall element integral with the carrier and extending from the back side in a vicinity of the through hole; introducing a first cleaning element into the first through hole such that an end portion of the first cleaning element is exposed on the backside of the carrier; treating the end portion of the first cleaning element such that it deforms and becomes wider than the first through hole; and deforming the first wall element until it at least partially extends over the deformed end portion of the first cleaning element such that the first cleaning element is effectively retained in its axial position. A brush having structural features resulting from the manufacturing method.

  • Publication number: 20190125065
    Abstract: A brush head for an oral care implement includes at least one (first) group of tufts extending from a mounting surface of a tuft carrier having a rotation axis. The tufts have a base end and a free end. The tufts of the first group are tufts having an extension in a circumferential direction about the rotation axis exceeding an extension in a radial direction. The tufts of the first group may be inclined with respect to the mounting surface in at least one direction. Each of the first-group tufts may comprise a first group of filaments and a second group of filaments, wherein the second-group filaments' free ends protrude beyond the first-group filaments' free ends.

  • Publication number: 20180000236
    Abstract: 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.

  • Patent number: 9579175
    Abstract: An oral-hygiene implement having a housing, a first carrier on which at least one first oral-treatment element is mounted, a second carrier on which at least one second oral-treatment element is mounted, wherein at least the first carrier element is mounted for driven oscillatory movement with a peak amplitude value relative to the housing and wherein the first and second oral-treatment elements are arranged such that the first oral-treatment element contacts the second oral-treatment element at least once during each oscillation period of the first carrier at a contact amplitude value smaller than the peak amplitude value and moves the second oral-treatment element out of its initial position until the peak amplitude value is reached.

  • Publication number: 20160367022
    Abstract: An oral hygiene implement, in particular a replacement brush head, that has a carrier assembly mounted at a housing part for movement relative to the housing part. The carrier assembly has at least two carriers arranged at a distance therebetween and an elongated, shaft-like connector element connected to the at least two carriers. The connector element has undercut sections at the locations where the carriers are connected to the connector element. The carriers are plastic-injection molded parts extending around the connector element so that the carriers are non-detachably connected to the connector element by a positive-fit connection. A method of assembling an oral hygiene implement is also provided.

  • Patent number: 9144299
    Abstract: 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.

  • Publication number: 20150257520
    Abstract: A head for an oral care implement has a mounting surface and at least one tuft mounted thereon. The tuft has a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis. The tuft comprises a plurality of substantially cylindrical filaments. Each filament has a longitudinal axis and a cross-sectional area extending in a plane that is perpendicular to the longitudinal axis. The cross-sectional area of an individual filament has a substantially non-circular shape. The plurality of filaments is arranged such that the cross-sectional area of the tuft has a scaled-up shape of the individual filament's cross-sectional area.
