Inflatable padded game ball
First Claim
1. An inflatable padded game ball, 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 impervious multi-layer bladder inside the liner assembly engaging the liner assembly over substantially its entire inner surface and comprising at least an inner and an outer simultaneously expandable layer;
the liner assembly comprising 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.

Abstract
An inflatable padded game ball, such as a football, having an outer carcass, a padding inside the carcass, a liner inside the padding and a bladder inside the liner. The liner is so dimensioned relative to the carcass that the liner establishes the final dimensions of the ball when the bladder is inflated within it. The bladder is air impervious and is formed of multiple layers to increase strength and durability. The liner is also formed of multiple layers including inner and outer woven fabric reinforcement layers and a plastic sheet middle layer for establishing the shape of the ball. The method of constructing such a ball includes a mold of smaller dimensions than the final dimensions of the ball which molds the shape of the inner liner. When the ball is removed from the mold the carcass and padding expand to the final size of the ball.
