Patent number: 10426249Abstract: An oral care implement that includes a handle and a head. A tuft of cleaning elements extends from the front surface of the head along an axis and includes a plurality of cleaning elements. In one embodiment, the cleaning elements may be formed of an elastomeric material. Furthermore, a sleeve may be coupled to the head and extend from the front surface of the head. The sleeve circumferentially surrounds a first portion of the tuft of cleaning elements and a second portion of the tuft of cleaning elements protrudes beyond a distal end of the sleeve. The sleeve may apply a radial compression force onto the first portions of the cleaning elements that are surrounded by the sleeves. The second portions of the cleaning elements may diverge as they extend from the distal end of the sleeve. The oral care implement may include sleeves of varying heights.Type: GrantFiled: September 1, 2016Date of Patent: October 1, 2019Assignee: Colgate-Palmolive CompanyInventors: Douglas Joseph Hohlbein, Chi Shing Wong

Patent number: 10278485Abstract: An oral care implement that includes a handle and a head. Cleaning elements are coupled to the head and extend from the front surface of the head. At least one of the cleaning elements is a first type of cleaning element that extends from a first end to a second end along a longitudinal axis and has a polygonal transverse cross-sectional shape. The first type of cleaning element has an outer surface having a plurality of elongated faces and a plurality of elongated edges. The first type of cleaning element is formed from a first component and a second component, the first and second components being different in at least one characteristic. An interface of the first and second components is located along at least one of the elongated edges.Type: GrantFiled: September 1, 2016Date of Patent: May 7, 2019Assignee: Colgate-Palmolive CompanyInventors: Douglas Joseph Hohlbein, Chi Shing Wong
