1. A sport ball comprising:
- a casing that forms at least a portion of an exterior surface of the ball;
an intermediate layer at least partially formed from a foam material, the intermediate layer being located directly adjacent to the casing and within the casing; and
a bladder located directly adjacent to the intermediate layer and within the intermediate layer,wherein the foam material of the intermediate layer directly bonds the casing to the bladder;
the bladder including an elastomeric material that substantially prevents air within the bladder from diffusing to the exterior of the ball.

Abstract
A sport ball may include a casing, an intermediate layer, and a bladder. In manufacturing the sport ball, a panel element of the casing and the bladder may be located in a mold, and a polymer foam material of the intermediate layer may be injected into an area between the bladder and the panel element. In addition, edges of panel element may be heatbonded to each other to join the panel elements and form seams of the casing.
