Abstract: 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.

Abstract: A cleaning section for an electric oral hygiene device includes a carrier mounted for driven rotation and/or oscillating rotation around a rotation axis, at least a plurality of first cleaning elements and a plurality of second cleaning elements, the cleaning elements being mounted on a mounting surface of the carrier. The carrier has an outer rim and an inner portion. The plurality of first cleaning elements are arranged at the inner portion of the carrier, and the plurality of second cleaning elements are arranged at the outer rim of the carrier. The plurality of first cleaning elements have a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis, the cross-shaped cross-sectional area having four projections and four channels, the projections and channels being arranged in an alternating manner.

Abstract: A handle for an oral-care implement, the handle comprises an electrical motor arranged to drive an output element structured and configured to couple the handle and a head attachable to and detachable from the handle; and a microcontroller for controlling the motor and to cause the output element to vibrate in (a) at least one oral-hygiene mode during which the oral-care implement is being used for an oral-hygiene routine, wherein the output element is vibrating at a substantially constant frequency, and (b) a disinfection mode during which the handle is being disinfected, before or after being used for the oral-hygiene routine, wherein the output element is continuously vibrating at a modulated frequency alternating within a frequency range of between about 140 Hz and about 250 Hz, for a duration of the disinfection mode.

Abstract: A handle for an oral-care implement for safe and hygienic use by multiple users includes an electrical motor and a detachable head. The handle has a display for displaying instructions to control functional operation of the handle, a microcontroller for controlling the motor and the display, and at least one switch to allow a user to control the functional operation of the handle, including causing the output element to vibrate in at least one oral-hygiene mode having an oral-hygiene frequency and causing the output element to vibrate in a disinfection mode when the handle is being disinfected before or after being used for the oral-hygiene routine. The disinfection mode has a modulated frequency, different from the oral-hygiene frequency, and alternating up and down between a low modulated frequency and a high modulated frequency, wherein the high modulated frequency is at least 50 percent greater than the low modulated frequency.

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.

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.

Abstract: A toothbrush head or a brush carrier having at least one carrier element including at least one shape-shifting tuft mounted thereon. The shape-shifting tuft raises from a mounting end on a mounting surface of the carrier element generally along an extension direction towards a free end of the shape-shifting tuft. The shape-shifting tuft has a length from the mounting base to the free end and comprises a plurality of fibers.

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.

Abstract: A toothbrush head includes a cleaning element carrier and one or more bristle tufts, each consisting of a plurality of bristle filaments connected to one another via a fuse ball. The fuse balls are embedded in the cleaning element carrier such that the balls are completely enclosed and the bristle filaments protrude from the carrier's front surface. At least two fuse balls are located at different levels in the carrier.
