  • Foraminous shell foam football
    Patent number: 5676611
    Abstract: A ball that has a foam outer shell which surrounds a hollow inner chamber. The ball is constructed by initially forming a first section and a separate second section. The first and second foam sections are attached to create a ball with an inner chamber. The outer shell and inner chamber create a moment of inertia that is conducive to a spiral rotation when thrown by a player. Additionally, the soft foam material of the outer shell minimizes the discomfort of catching the ball.
