Multi-piece golf balls containing a multi-layered core structure are provided. The core structure includes a small, heavy inner core (center) having a relatively high specific gravity, an intermediate core layer, and a surrounding outer core layer. The layers of the core structure may have different hardness gradients. In one preferred embodiment, each core layer has a positive hardness gradient. The center of the core comprises a metal material such as copper, steel, brass, tungsten, titanium, aluminum, and alloys thereof. The intermediate core layer is preferably formed from a thermoset composition such as polybutadiene rubber, and the outer core layer is preferably formed from a thermoplastic composition such as an ethylene acid copolymer. The resulting ball has high resiliency and good spin control.

The invention herein is directed to an Easter related game and method of play. The invention is intended to be played during Easter celebration, preferably by re-using found Easter Eggs or alternatively with any rollable oval, oblong, or ovoid object. The game of this invention comprising the following tools or game pieces: a rolling ramp and a plurality of oval, oblong, or ovoid objects, preferably Easter eggs. The game may be played by one or more participant or groups of participants.

The center of the core comprises a metal material such as copper, steel, brass, tungsten, titanium, aluminum, and alloys thereof. The intermediate core layer is preferably formed from a first thermoset composition such as polybutadiene rubber, and the outer core layer is preferably formed from a second thermoset composition. The resulting ball has high resiliency and good spin control.

A golf ball with a cover formed by spraying is disclosed herein. In the present invention, a mixture of a low viscous diisocyanate component and a diamine free of organic solvent are sprayed onto a mantle insert to form a cover layer for a golf ball. A rapid reaction occurs and a solid layer forms within ten seconds. The polyurea material is extremely durable so that the cover layer performs with excellent shear cut durability.

The present invention is directed to golf balls having improved aerodynamic performance due, at least in part, to the alteration of the dimple surfaces. In particular, the present invention relates to a golf ball that includes at least a portion of its dimples having circular perimeters and dimple profiles having a concentric groove or a non-concentric groove on the surface of the dimple. The golf ball dimples of the present invention provide golf ball surfaces having unique appearances, while maintaining ideal aerodynamic characteristics.

Disclosed herein are polyurethane golf ball compositions. The compositions are prepared by adding a UV absorber to a polyol prior to reacting the polyol with an isocyanate to form a prepolymer, which is then reacted with a curing agent to form the polyurethane.

A golf ball dimple pattern based on a hexagonal dipyramid is disclosed. The dimples are arranged based on six substantially similar dimple sections on each of the two hemispheres of the ball.

A ball has a lightweight inner bladder and an outer layer that covers the inner bladder. The inner bladder bunches up against the inner surface of the outer layer. The bunched up surface of the inner bladder may be flattened upon impact, thereby absorbing energy. The bunched up inner bladder may create an uneven surface on the outer layer thereby altering the manner through which the ball travels through the air. The outer layer may be provided with lines, indentations, graphics and/or other features that improve the performance of the ball and/or that replicate some or all of the characteristics of the exterior surface of the regulation ball it simulates. The ball may be configured for any of a variety of sports or games.
