1. An improved golf ball comprising:

  • a hollow, spherical shell of a deformable polymeric material and a unitary core of a material which, at the time of introduction into the shell, is a liquid or can be handled as a liquid and which forms a substantially homogeneous core that substantially fills the hollow spherical shell without stressing the spherical shell;

    the structural characteristics of the spherical shell and the core being such that the improved golf ball has a high coefficient of restitution, so that when the improved golf ball is struck by a golf club, the improved golf ball has an initial velocity which approaches the maximum allowable limits imposed by the U.S.G.A. and so that when the improved golf ball is struck by the golf club, the improved golf ball may be driven at long distances in regulation play.
