<p>An inflatable padded game ball, such as a football, comprising an outer carcass of relatively tough durable material, padding disposed within the carcass and engaging the carcass over substantially its entire inner surface, a liner assembly contained within the carcass on the inside of the padding and engaging the padding over substantially its entire inner surface, and an air-impervi-ous multi-layer bladder inside the liner assembly engaging the liner assembly over substantially its entire inner surface and comprising at least an inner layer and an outer layer. The liner assembly comprises at least two layers, including a layer of plastic sheet material having a shape, under normal ball inflation pressures, substantially conforming to the final inflated shape of the game ball and being substantially dimensionally stable to hold said shape under said normal ball inflation pressures, and an outer layer adjacent the padding. A method of making a game ball of the present invention is also disclosed.</p> |
