ABSTRACT:
The present invention is directed to improved multi-layer golf balls. In this regard, a smaller and lighter core is produced and metal particles, or other heavy weight filler materials, are included in the cover compositions. This results in a molded golf ball exhibiting enhanced perimeter weighting. Preferably, the particles are included in a relatively thick inner cover layer (or mantle) of a solid, three-piece multi-layered golf ball. In another preferred version, one or more patterns of weighting material are incorporated in the ball, and most preferably along the outer periphery of the ball so that the pattern is visible along the ball's exterior. A wide array of shapes and sizes of the patterns may be used. The size and weight of the core is reduced in order to produce an overall golf ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association. The particles or weighting material preferably have a size ranging from about 10 to about 325 mesh. In another preferred version, the weighting material is incorporated in a cover layer in an amount of from about 1 to about 100 parts per 100 parts of cover layer material. And, in another preferred version, the weighting material is incorporated in a golf ball having a multi-layer cover. The cover may utilize an inner layer that includes a material having a flexural modulus of at least about 15,000 psi and a hardness of at least about 60 Shore D. The cover may also utilize an outer layer that includes a material having a flexural modulus of from about 1,000 to about 10,000 psi and a Shore D hardness of about 65 or less. The weighting material is disposed in at least one of the inner or outer cover layer.
