| abstract |
A golf ball comprising an inner core, an outer core, and a cover is disclosed. The outer core surrounds the inner core, and the cover encases the cores. The inner core has a plurality of projections forming gaps between each projection, where the free ends of the projections form a spheroid-shaped surface. The inner core is formed of a first material and the outer core is formed of a second material. The outer core is non-wound, and the second material is disposed within the gaps in the inner core so that the outer surface of the outer core is substantially spherical. The first and second materials have substantially different material properties. In one embodiment, the projections have enlarged free ends. In another embodiment, the projections taper from a base outward. In yet another embodiment, the maximum length of each projection is greater than the maximum width. |
