Abstract:
The present invention is directed to a ball including an outer shell formed from a first thermoplastic material and having an inner surface defining a cavity, outer details formed from a second thermoplastic material and disposed on at least a portion of the outer surface of the outer shell, and a core formed from a foamable polymeric material and disposed within the cavity of the outer shell. The ball may be produced by forming a pair of half shells having inner surfaces defining corresponding portions of the cavity of the outer shell, forming the outer details on the outer surface of at least one of the half shells, and foaming a polymeric material to form the core.
