Publication number: 20250009118Abstract: An oral care implement that includes a handle and an oral care refill head. The oral care refill head is alterable between a first state in which it is separated from the handle and a second state in which it is coupled to the handle. The oral care refill head has a proximal edge surface that defines an opening into a sleeve cavity. The proximal edge surface may be inclined in one direction only as it extends from an inner edge surface to an outer edge surface. The handle may have a gripping portion and a stem, with a distal end of the gripping portion forming an annular shoulder surface that surrounds the stem. The annular shoulder surface may be inclined in one direction only as it extends from an inner shoulder edge adjacent to the stem to an outer shoulder edge adjacent to an outer surface of the handle.Type: ApplicationFiled: September 13, 2024Publication date: January 9, 2025Applicant: Colgate-Palmolive CompanyInventors: Al Aquanza SPROSTA, Eduardo Jimenez, Douglas Hohlbein, Michael Rooney, Yanmei Ji, Xiangji Ding
