摘要： 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.
摘要翻译：一种用于动物的超强韧的模制弹性咀嚼聚氨酯玩具。玩具可以成形为模拟狗骨，并在咀嚼时使吞咽困难。它在动物的消化系统中也是化学惰性的，其特征在于硬度适中，弹性变形，拉伸强度大，抗剪切性能好。它通常比水略重，但是可以发泡或用空气浸渍以漂浮。该玩具还利用了聚氨酯的独特性质，使得将动物的令人愉悦的表面迁移调味剂与聚氨酯组合物混合，而后者在模制成所需形状之前处于液相。因此，由于香味被咀嚼或者从玩具的外表面消散，所以调味剂被不断补充。
