Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
183 words
A molded one-piece polyurethane dog bone having an elongated body and enlarged opposite end portions; said bone having opposite lateral surfaces and upper and lower surfaces curving in compound curvatures; said curvatures comprising said upper and lower surfaces of said elongated body extending in one direction from the mid-region of said body curving upwardly, the upper and lower surfaces of said body extending in the opposite direction from said mid-region curving downwardly, the upper and lower surfaces of the end portion in said one direction curving upwardly and downwardly respectively, the last named upper surface comprising a continuation of the upward curvature of said upper surface of said body, the last named lower surface recurving downwardly from the upward curvature of said lower surface of said body, the upper and lower surfaces of the end portion in said opposite direction curving upwardly and downwardly respectively, the last named upper surface recurving upwardly from the downward curvature of said upper surface of said body, and the last named lower surface comprising a continuation of the downward curvature of said lower surface of said body.
Claim 2
Dependent Claim
183 words
A molded one-piece polyurethane dog bone having an elongated body and enlarged opposite end portions; said bone having opposite lateral surfaces and upper and lower surfaces curving in compound curvatures; said curvatures comprising said upper and lower surfaces of said elongated body extending in one direction from the mid-region of said body curving upwardly, the upper and lower surfaces of said body extending in the opposite direction from said mid-region curving downwardly, the upper and lower surfaces of the end portion in said one direction curving upwardly and downwardly respectively, the last named upper surface comprising a continuation of the upward curvature of said upper surface of said body, the last named lower surface recurving downwardly from the upward curvature of said lower surface of said body, the upper and lower surfaces of the end portion in said opposite direction curving upwardly and downwardly respectively, the last named upper surface recurving upwardly from the downward curvature of said upper surface of said body, and the last named lower surface comprising a continuation of the downward curvature of said lower surface of said body.
Claim 3
Dependent Claim
41 words
A polyurethane dog bone according to claim 1, each said enlarged end portion bifurcating laterally and extending endwise from the associated end of said elongated body for approximately one-third the length of said bone from said mid-region to said associated end.
Claim 4
Dependent Claim
41 words
A polyurethane dog bone according to claim 2, the total transverse sectional area of the two bifurcated end portions of said bone at either end thereof being on the order of magnitude of the transverse sectional area of said longitudinal body.
Claim 5
Dependent Claim
41 words
A polyurethane dog bone according to claim 2, said elongated body being generally heart shaped in transverse section to provide a centrally located upwardly opening channel extending along its upper surface and a centrally located ridge extending along its bottom surface.
Claim 6
Dependent Claim
24 words
A polyurethane dog bone according to claim 4, the depth of said channel being approximately one-third the distance between said upper and lower surfaces.
Claim 7
Dependent Claim
38 words
A polyurethane dog bone according to claim 5, the total transverse sectional area of the two bifurcated end portions of said bone at either end thereof being approximately equal to the transverse sectional area of said longitudinal body.
Claim 8
Dependent Claim
27 words
A chewable toy for an animal, said toy comprising a molded elastomeric polyurethane material containing a surface-migrating flavoring extract dispersed within the molecular structure of said material.
Claim 9
Dependent Claim
27 words
A chewable toy for an animal, said toy comprising a molded elastomeric polyurethane material containing a surface-migrating flavoring extract dispersed within the molecular structure of said material.
Claim 10
Dependent Claim
30 words
A chewable toy according to claim 7, comprising the product of adding said extract to the polyurethane material when the latter is in a liquid phase prior to being molded.
Claim 11
Dependent Claim
27 words
A chewable toy according to claim 7, comprising the product of adding said extract during the formulation and mixing of the polymerizable liquid components of said polyurethane.
Claim 12
Dependent Claim
166 words
A chewable toy according to claim 7, said toy comprising a one-piece simulated bone having an elongated body and enlarged opposite end portions; said bone having opposite lateral surfaces and upper and lower surfaces curving in compound curvatures; said curvatures comprising said upper and lower surfaces of said elongated body extending in one direction from the mid-region of said body curving upwardly, the upper and lower surfaces of said body extending in the opposite direction from said mid-region curving downwardly, the upper and lower surfaces of the end portion in said one direction curving upwardly and downwardly respectively, the last named upper surface comprising a continuation of the upward curvature of said lower surface of said body, the upper and lower surfaces of the end portion in said opposite last named upper surface recurving upwardly from the downward curvature of said upper surface of said body, and the last named lower surface comprising a continuation of the downward curvature of said lower surface of said body.
Claim 13
Dependent Claim
74 words
A chewable toy according to claim 10, each said enlarged end portion bifurcating laterally and extending axially endwise from the associated end of said elongated body for approximately one-third the length of said bone from said mid-region to said associated end, the total transverse sectional area of the two bifurcated end portions of said bone at either end thereof being on the order of magnitude of the transverse sectional area of said longitudinal body.
