Abstract: An interdental cleaner has a gripping portion (3) and a cleaning portion (4) formed by an elongate body made from a thermoplastic material. The cleaning portion (4) has a coating made of a self-adhesive, heat-vulcanized rubber material forming peripheral, flexible brush members (6).

Abstract: The disclosure relates to a method of manufacturing a toothbrush handle and includes heating a pelletized polyolefin based (preferably polyethylene based) polymeric material having a biobased content of at least 60% by weight, and injection moulding the heated polymeric material into a moulding cavity thereby forming a toothbrush handle. The moulding cavity has the shape of a toothbrush handle comprising a gripping portion and a bristle support portion. The disclosure also relates to toothbrush handle, a toothbrush and a method of manufacturing a toothbrush.

Abstract: A method of providing an insertion guidance tip at a distal end of an interdental brush, use of a first set of filaments and a second set of filaments in an interdental brush, and an interdental brush comprising a first set of filaments arranged along a first longitudinal sub-length and having a first filament diameter, and a second set of filaments arranged along a second longitudinal sub-length and having a second filament diameter, wherein the second filament diameter is smaller than the first filament diameter, wherein the second longitudinal sub-length is positioned at the distal end of the interdental brush, and wherein the second sub-length has a length along the longitudinal direction being less than 15% of a longitudinal extension of the brush portion and extending along less than three twists of a core member.

Abstract: An interdental cleaner has a gripping portion (3) and a cleaning portion (4) formed by an elongate body made from a thermoplastic material. The cleaning portion (4) has a coating made of a self-adhesive, heat-vulcanized rubber material forming peripheral, flexible brush members (6).

Abstract: A method for end rounding bristles of a brush section includes providing a focused laser beam propagating along a geometrical main propagation direction and having a main irradiation spot, providing a relative motion between an end of each bristle and the main irradiation spot of the focused laser beam such that the end of each bristle is moved through the main irradiation spot in a path having a main component transverse to a longitudinal extension of the bristle, wherein the focused laser beam is directed such that the geometrical main propagation direction has a main component transverse to the longitudinal extension of respective bristle having its end at the main irradiation spot, whereby a rounding of the end is provided by the focused laser beam heating the end and causing it to partly melt and form a rounded end, and providing a relative motion between the main irradiation spot and the brush section along a direction having a main component being transverse to the path, thereby subjecting in sequence

Abstract: An interdental brush comprises a brush member having bristle filaments attached to a spine which projects from a handle part. The handle part comprises a main body and a resilient transition portion. The handle part further comprises a hollow cavity, in the transition portion. The hollow cavity improves the cushioning effect of the transition portion, and increases the length of stroke of the interdental brush by allowing the transition portion to be deformed.

Abstract: The invention depicts a detachable brush comprising a brush portion (60) and a fastening portion (50) that extends along a first axis (C). The fastening portion (50), in order to be retained by a handle, comprises a first surface (52a) being angled in a first direction such that a normal of the first surface has at least a component in a first direction along said first axis (C), and a second surface (53a) being angled in a second direction such that a normal of the second surface has at least a component in a second direction, opposite to the first direction, along said first axis (C). The invention further depicts a handle with retainer portions shaped to receive and carry the detachable brush.
