Oral care implement

An oral care implement comprising:

• a head portion having a front surface;
• a plurality of bristle tufts extending from the front surface;
• a cup member extending from the front surface of the head portion along a first axis, the cup member comprising:
• a top surface;
• a plurality of grooves formed into the top surface, each of the grooves extending along a groove axis that extends radially outward from the first axis;
• the grooves comprising a plurality of first grooves and a plurality of second grooves, and wherein, taken along a reference cylinder about the first axis, each of the first grooves has a first transverse cross-section and each of the second grooves has a second transverse cross-section, the first and second transverse cross-sections being different from one another;
• wherein each of the first grooves has a groove floor having a longitudinally concave shape;
• and wherein each of the second grooves has a groove floor that slopes downward with distance from the first axis.

An oral care implement comprising:

• a head portion having a front surface;
• a plurality of bristle tufts extending from the front surface;
• a cup member extending from the front surface of the head portion along a first axis, the cup member comprising:
• a top surface;
• a plurality of grooves formed into the top surface;
• a plurality of rib members, wherein adjacent ones of the grooves are separated by one of the rib members, each of the rib members extending along a rib axis that extends radially outward from the first axis, and wherein each of the rib members has a thickness that increases with distance from the first axis;
• wherein the grooves have a depth that increases with distance from the first axis.
