Patent number: 10238204Abstract: An oral care implement is provided comprising a head comprising a first face having a plurality of cleaning elements extending therefrom. The head has a length and a width perpendicular to the length. The head has a proximal section adjacent to the handle and a distal section remote from the handle, the proximal section having a first maximum width and the distal section having a second maximum width, wherein the second maximum width is less than the first maximum width. The distal and proximal sections are located adjacent to one another and are joined at a waist section that has a third maximum width which is less than the second maximum width. At least one bristle tuft having a distal end remote from the first face is provided that comprises bristles of varying lengths so as to form a cup-shaped recess at the distal end of the bristle tuft.Type: GrantFiled: November 5, 2013Date of Patent: March 26, 2019Assignee: Colgate-Palmolive CompanyInventors: David Kyung Min Lee, Robert Moskovich

Patent number: 10172442Abstract: An oral care implement including a body comprising a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending therefrom; a reservoir, in the body, for storing an oral care fluid; and a pump for pumping the oral care fluid from the reservoir towards the fluid outlet, wherein the pump comprises a first check valve downstream of the reservoir, and a second check valve downstream of the first check valve and upstream of the fluid outlet. One of the first and second check valves comprises a valve seat defining an opening through which the oral care fluid is flowable, a valve member separate from the valve seat and comprising a stopper movable linearly relative to the valve seat, and a resilient element separate from the valve member and biasing the stopper towards the valve seat.Type: GrantFiled: August 18, 2014Date of Patent: January 8, 2019Assignee: Colgate-Palmolive CompanyInventors: Donghui Wu, David Kyung Min Lee

Patent number: 10039370Abstract: An oral care implement comprising a head and a handle is provided. The head comprises first and second faces. The first face includes a plurality of cleaning elements extending therefrom. The second face is located on an opposite side of the head to the first face. The head has a length in a direction along a longitudinal axis of the handle, and a width perpendicular to the length. The head has a proximal section adjacent to the handle and a distal section remote from the handle. The proximal section has a first maximum width and the distal section has a second maximum width, wherein the second maximum width is less than the first maximum width. The second face comprises a tissue cleanser, the tissue cleanser extending over a distal-most edge of the head and forming a ridge located on the distal-most edge of the head.Type: GrantFiled: November 5, 2013Date of Patent: August 7, 2018Assignee: Colgate-Palmolive CompanyInventors: David Kyung Min Lee, Robert Moskovich
