Golf ball incorporating pair of thin hemispherical cups having targeted configuration/geometry and being compression molded about large, soft subassembly/core

摘要

Golf ball having CoR of at least 0.700 and comprising: a substantially spherical subassembly having diameter of 1.3 inches or greater and compression of from about 15-60; and a thin outer layer having a compression molded thickness of about 0.015-0.055 inches and consisting of first and second hemispherical cups consisting of a polymer composition having a melt flow index at 190° C. under a 2.16-kg load of from about 0.8 g/10 min. to about 4 g/10 min. and having a cup thickness ratio of from about 1.10 to 1.70 as well as an inner surface that is sized, shaped and contoured to receive and conformally and adhesively mate onto and about the subassembly during compression molding such that the subassembly in the finished golf ball is substantially spherical and disposed concentrically within the thin outer layer. Also, the novel hemispherical cups and the method of making the golf ball.
