Method of forming tossable device including game-ball unit
First Claim
1. In relation to the making of a tossable device which includes a generally ball-shaped unit, a method for creating such a unit comprisingforming, by molding, an inner core subunit utilizing a high-resilience, polyurethane foam material,lining the wall of a mold cavity which is larger than such a formed inner core subunit with a thin film of an outer, skin-forming material,suspending the inner core subunit generally centrally within, and circumsurroundedly spaced from, the lined mold cavity wall,filling the space intermediate the inner core subunit and the lined mold cavity wall with a soft, slow-return spongy polyurethane foam material, thus to form an outer core subunit encasing the inner core subunit and encased by the skin-forming material, andremoving from the mold cavity, in the form of the desired ball-shaped unit, the assembly including the inner and outer core subunits and the skin-forming material.

Abstract
A method of forming a ball-shaped unit including (1) molding an inner core subunit from a high-resilience, polyurethane foam material, (2) lining the wall of a mold cavity which is larger than such a formed inner core subunit with a thin film of an outer, skin-forming material--preferably a water-based, pigmented, acrylic emulsion, barrier release coating for urethane foam, (3) suspending the inner core subunit generally centrally within and circumsurroundedly spaced from the lined mold cavity wall, (4) filling the space intermediate the inner core subunit and the lined mold cavity wall with a soft, slow-return, polyurethane material thus to form an outer core subunit which encases the inner core subunit and which is encased by the skin-forming material, and (5) removing from the mold cavity, in the form of the desired ball-shaped unit, the assembly including the inner and outer core subunits and the skin-forming material.
