The Patent Description & Claims data below is from USPTO Patent Application 20080015054, Golf ball.

1. A golf ball comprising: a liquid core comprising a substantially spherical shell defining a hollow interior region and a liquid disposed within the hollow interior of the shell where the shell can be one or more layers; and a cover layer disposed about the core, the cover layer comprising a material selected from the group consisting of reaction-injection-molded polyurethane, reaction-injection-molded polyurethane/polyurea, reaction-injection-molded polyurea, and combinations thereof,

2. The golf ball according to claim 1, wherein the core has a size of from about 0.620 to about 1.725 inches.

3. The golf ball according to claim 1, wherein the spherical shell of the core comprises a high acid ionomer.

4. The golf ball according to claim 1, wherein the liquid is selected from the group consisting of a salt solution, sugar solution, and sugar/salt solution.

5. The golf ball according to claim 1, wherein the cover layer comprises a reaction-injection-molded polyurethane.

6. The golf ball according to claim 1, wherein the cover layer has a thickness of from about 0.005 to about 0.100 inches.

7. The golf ball according to claim 1, wherein the cover layer has a Shore B hardness of from about 60 to about 100.

8. The golf ball according to claim 1, wherein the core has a Shore D hardness of from about 45 to about 85.

9. The golf ball according to claim 1, wherein the liquid is a solution comprising an inorganic salt selected from the group consisting of calcium chloride, sodium chloride, potassium chloride, zinc chloride, potassium iodide, calcium iodide, zinc iodide, magnesium iodide, and combinations thereof.

10. A golf ball comprising: a liquid core; a mantle layer disposed over the core; and a cover layer disposed about the second mantle layer, the cover layer comprising a reaction-injection-molded polyurethane, a reaction-injection-molded polyurethane/polyurea, a reaction-injection-molded polyurea, and combinations thereof.

11. The golf ball according to claim 10, wherein the core comprises a salt solution comprising an inorganic salt.

12. The golf ball according to claim 10, wherein the liquid of the core has a viscosity of from about 0.5 to about 5000 cPs.

13. The golf ball according to claim 10, wherein the liquid of the core has a specific gravity of from about 0.85 to about 2.0.

14. The golf ball according to claim 10, wherein the cover layer comprises a reaction-injection-molded polyurethane.

15. The golf ball according to claim 10, wherein the cover layer comprises a reaction-injection-molded polyurethane/polyurea.

16. The golf ball according to claim 10, wherein the cover layer comprises a reaction-injection-molded polyurea.

17. The golf ball according to claim 10, wherein the mantle layer has a hardness of from about 50 to about 80.

18. The golf ball according to claim 10, wherein the core layer has a hardness of from about 50 to about 80.

19. A golf ball comprising: a core comprising i) a substantially spherical shell defining a hollow interior, and ii) a liquid disposed in the interior of the shell, the core having a Shore D hardness of at least about 50; a cover layer disposed about the core, the cover layer comprising a reaction-injection-molded polyurethane, a reaction-injection-molded polyurethane/polyurea, a reaction-injection-molded polyurea, and combinations thereof; and at least one mantle layer intermediate the core and the cover layer, the at least one mantle layer having a Shore D hardness of at least about 50. The golf ball according to claim 19, wherein the liquid is a inorganic salt solution comprising a metal selected from the group consisting of sodium, calcium, potassium, magnesium, and zinc.

20. The golf ball according to claim 19, wherein the liquid has a viscosity of from about 1 to about 5000 cPs.

21. The golf ball according to claim 19, wherein the liquid has a specific gravity of from about 1 to about 2.

22. The golf ball according to claim 19, wherein the cover has a thickness of from about 0.005 to about 0.100 inches.

23. The golf ball according to claim 19, wherein the shell comprises a high acid ionomer.
