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.

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.

2. A golf ball comprising:
-
a hollow, spherical shell formed of hemispheres spin welded together adjacent to its equator with an interface in a tongue and groove configuration, the shell being formed of a deformable polymeric material with a thickness of about 0.090 inches; a non-cellular, unitary, substantially homogenous core of a core material which at the time of its introduction into the shell, is a liquid or can be handled as a liquid; and a plug filling a hole in the shell through which the core material was introduced;
the structural characteristics of the shell and core material being such that the golf ball has a high co-efficient of restitution and conforms to the initial velocity requirements of the U.S.G.A. and such that the golf ball may be driven long distances in regulation play.

3. An improved golf ball that has a high coefficient of restitution, that conforms to the initial velocity requirements of the U.S.G.A., and that may, in regulation play, be driven long distances, in terms of both carry and roll, as a result of being struck by a golf club, the improved golf ball comprising:
- a substantially spherical shell of polymeric material and a core material that substantially fills the spherical shell without stressing the spherical shell, where the spherical shell is substantially solely responsible for the initial velocity of the golf ball when the golf ball is struck by the golf club and which allows the golf ball to be driven long distances both in the air and on the ground when it lands.
