A golf ball having an outside diameter of at least 1.70 inches which includes a core, an inner cover, or mantle, and an outside cover. The mantle and the outer cover have a different Shore D hardness. Dimples cover at least seventy percent of the outer surface area of the ball. In one embodiment, the mantle has a Shore D hardness between 50 and 60 and the cover has a Shore D hardness of 65 or less with the mantle hardness being greater than the cover hardness. In another embodiment, the mantle has a Shore D hardness of 65 or less and the cover has a Shore D hardness between 50 and 60, with the cover hardness being greater than the mantle hardness.

Golf ball

The present invention is directed to improved multi-layer golf ball compositions having a core, an inner cover and an outer cover and the resulting regulation balls produced using these compositions. In this regard, a smaller and lighter core is produced and metal particles, or other heavy weight filler materials, are included in the inner cover compositions. This results in a molded golf ball exhibiting enhanced interior perimeter weighting. the heavy weight filler particles, such as powdered metals, are included in a relatively thick inner cover layer (or mantle) formed from an ionomer resin of a solid, three-piece multi-layered golf ball. The size and weight of the core can thereby be 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. It has been found that the combination of the present invention produces a golf ball with an increased moment of inertia and/or a greater radius of gyration and thus generates lower spin due to the increased weight of the inner cover layer. This results in a golf ball exhibiting enhanced distance without substantially effecting the feel and durability characteristics of the ball.

Golf ball and method of producing same

A golf ball including two poles and an equator is characterized by the arrangement of a preselected number of dimples in a geometrical lattice configuration based upon a subdivided tetrahedron on the surface thereof The lattice includes six dimple-free great circles around the circumference of the ball, one of the circles corresponding with the equator and another of the circles passing through the poles. All of the circles define twenty-four generally equivalent triangles, twelve in each hemisphere of the ball. An equal number of dimples are arranged within each of the triangles, and the dimple arrangement in at least two of the triangles is different from the dimple arrangement in the remaining triangles.

Tetrahedral dimple pattern golf ball

A golf ball having an outside diameter of substantially 1.70 to 1.80 inches and a weight no grater than 1.62 ounces.

Disclosed herein is a multi-layer golf ball having a central core, an inner cover layer containing a non-ionomeric polyolefin material, preferably a plastomer, and an outer cover layer comprising a thermoplastic material. The combined thickness of the inner and outer cover layer preferably is at least about 0.10 inches. The golf ball has a coefficient of restitution of at least about 0.780. When the inner cover layer contains a non-ionomeric material such as a metallocene-catalyzed polyolefin and the outer cover layer contains ionomer, the golf ball of the invention can be configured to have playability properties comparable to those of golf balls which contain substantially higher quantities of ionomer. A method for forming the golf ball described above also is disclosed.

Multi-layer golf ball

An object with a hologram image and method of fabrication comprising a first outermost layer. Such first layer has an exterior surface and an interior surface. The first layer is formed of a coating with a diffraction grating on its interior most surface. The first layer is coated with a solution, either solvent or water born, and is of a transparent material which is an ultraviolet stabilized polymer. The material of the first layer is an acrylic polymer, preferably polyurethane and constitutes a flexible metalized sheet. A second layer has an exterior surface and an interior surface. The second layer is formed of a reflective layer of aluminum deposit vacuum. A third innermost layer has an exterior surface and an interior surface. The third layer is formed of hot melt adhesive.

Game ball with a hologram image

A golf ball of improved playing characteristics weighing no more than 1.62 ounces and having a core and cover, a mean outside diameter of between 1.73 inches and 1.75 inches, a cover thickness of 0.125 inches or greater and a cover hardness of Shore D60 or greater.
