Abstract
An improved golf ball comprising a hollow, spherical shell of a polymeric material; a unitary, noncellular core of a material which, at the time of introduction into the shell, is a liquid and a one-piece spherical cover over the center. The spherical shell, as opposed to the core, is primarily responsible for the high initial velocity obtained when the golf ball is struck by a golf club so as to allow the golf ball to be driven long distances both in the air and on the ground when it lands. In an alternate embodiment, the center and cover are of a one-piece, blow-molded construction.
