Abstract
Golf ball comprising a core and a cover, wherein the core includes between 2 and 20 smaller spheres that are surrounded by a second core composition having at least one different physical property than the composition(s) forming the smaller spheres. The smaller spheres can be entirely surrounded by the second core composition; or, at least two smaller adjacent spheres may each be partially surrounded by the second core composition while also being in partial contact with each other.
Claims6
A golf ball comprising a core and a cover, wherein the core has a core center and comprises four first smaller spheres and four second smaller spheres;
- wherein the four first smaller spheres:
- are disposed about the core center without intersecting it;
- are each comprised of a first core composition;
- are each tangent to two other first smaller spheres;
- have diameters D1, D2, D3, and D4, wherein D1=D2=D3=D4;
- are located distances X1, X2, X3, X4, from the core center, wherein:
- X1=X2=X3=X4;
- and
- X1 is greater than ½ D1;
- and
- wherein the four second smaller spheres:
- surround and are disposed between adjacent first smaller spheres;
- are each comprised of a third core composition;
- have diameters D5, D6, D7, and D8, wherein D5=D6=D7=D8;
- are located distances X5, X6, X7, and X8 from the core center, wherein:
- X5=X6=X7=X8;
- D5 is less than D1;
- and
- X5 is greater than X1;
- and
- wherein each of the first smaller spheres and each of the second smaller spheres is surrounded by a second core composition that has at least one different physical property than at least one physical property of the first core composition and the third core composition.
