Abstract
A super-tough molded elastomeric chewable polyurethane toy for an animal. The toy may be shaped to simulate a dog bone and to make swallowing difficult when being chewed. It is also chemically inert in the animal's digestive system and is characterized by moderate hardness, resilient deformability, large tensile strength and resistance to shearing. It is generally slightly heavier than water, but may be foamed or impregnated with air to float. The toy also makes use of a unique property of polyurethane whereby a surface-migrating flavoring pleasing to the animal is mixed with the polyurethane composition while the latter is in a liquid phase prior to being molded to the desired shape. Thus as the flavoring is chewed off or otherwise dissipated from the exterior surface of the toy, the flavoring is continuously replenished.
