Claims8
A game ball comprising:
- a carcass made up of a plurality of carcass segments, which are sewn together so as to form said carcass, each of said carcass segments having a major portion and a marginal portion that surrounds said major portion and that is thinner than said major portion, and including
- an outer layer having an outer surface, an inner surface opposite to said outer surface, a center, and a periphery,
- an intermediate layer adhered to said outer layer, and having a shape that corresponds to that of said outer layer, said intermediate layer having an outer surface adhered to said inner surface of said outer layer, an inner surface opposite to said outer surface of said intermediate layer, and a periphery, and
- an inner layer adhered to said inner surface of said intermediate layer, and having a shape that corresponds to that of said outer layer, said inner layer having a periphery heat-sealed to said inner surfaces of said outer and intermediate layers, and said inner layer has an area slightly larger than that of said outer layer.

- an inner layer adhered to said inner surface of said intermediate layer, and having a shape that corresponds to that of said outer layer, said inner layer having a periphery heat-sealed to said inner surfaces of said outer and intermediate layers,
- wherein said periphery of said outer layer has a first distance from said center along a radial direction with respect to said center, said periphery of said intermediate layer having a second distance from said center along the radial direction that is shorter than said first distance so that said periphery of said intermediate layer extends inside said periphery of said outer layer, said intermediate layer having a uniform thickness, said inner layer being stepped and having a central portion that abuts against said inner surface of said intermediate layer, said periphery of said inner layer abutting against said inner surface of said outer layer, and
- wherein said periphery of said outer layer has a first distance from said center along a radial direction with respect to said center, said periphery of said intermediate layer having a second distance from said center along the radial direction that is shorter than said first distance so that said periphery of said intermediate layer extends inside said periphery of said outer layer, said intermediate layer having a uniform thickness, said inner layer being stepped and having a central portion that abuts against said inner surface of said intermediate layer, said periphery of said inner layer abutting against said inner surface of said outer layer.
