Patent number: 11284707Abstract: A filament for an oral care implement has 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 has four projections and four channels. The projections and channels are arranged in an alternating manner. Each channel has a concave curvature formed by neighboring and converging projections. The concave curvature has a radius, and each projection is end-rounded thereby forming a curvature. The curvature has a diameter, and the ratio of the diameter of the curvature of the projection to the radius of the curvature of the channel is from about 0.2 to about 1.5.Type: GrantFiled: October 10, 2017Date of Patent: March 29, 2022Assignee: The Procter & Gamble CompanyInventors: Erwin Paul Mark, Jochen Erich Kawerau, Jens Alinski, Sven Alexander Franke, Karen Lynn Claire-Zimmet, Uwe Jungnickel
