Abstract
A chewable animal toy comprising principally an ethylene/methacrylic acid copolymer, ionically cross-linked ionomer resin. The metal component in this polymer is sodium. The hardness of the toy on a "D" scale is 65-99 with a preferred range of 75-85. A starch-based flavoring additive is dispersed throughout the body of the animal toy. In the process of making the animal toy, the flavoring additive is dry mixed with pellets of the ionomer resin before melting and die injection molding the toy. The product is an ingestion safe toy that resists puncturing, cracking, splintering, or shattering, but shaves off to provide a roughening and bristling finish which is desirable for the satisfaction and hygiene of the animal.
