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.
Claims19
A chewable animal toy comprised of a single ethylene/methacrylic acid copolymer, ionically cross-linked ionomer resin having a hardness such that when chewed by an intended animal, the toy does not puncture, splinter, shatter, or crack, or prevent biting into said resin but instead shaves off and roughens and bristles whereby the animal is satisfied with the gnawing action and the animal's teeth are scoured and cleaned.
An animal toy comprised of an ethylene/methacrylic acid copolymer, ionically cross-linked ionomer resin having a hardness such that when chewed by an intended the animal, the toy does not puncture, splinter, shatter, or crack prevent biting into said resin but instead shaves off and roughens and bristles whereby the animal is satisfied with the gnawing action and the animal's teeth are scoured and cleaned and a starch-based flavoring additive dispersed throughout the entire body of said toy.
An animal toy in the form of a dog bone, comprising an ethylene/methacrylic acid copolymer, ionically cross-linked, ionomer resin having the general formula:
- ##STR3## where M.sup.+ is sodium and wherein the hardness is between 75-85 on the "D" scale, and also comprising 0.4%-1.25% of a spray dried starch-based artificial and natural flavor comprising dextrin, modified food starch, gum arabic, propylene glycol and vegetable oil.
The method of making a chewable animal toy, comprising dry-mixing pellets of ethylene/methacrylic acid copolymer, ionically cross-linked, ionomer resin, with approximately 0.4%-1.25% of a starch-based flavoring additive, melting to a temperature of approximately 350.degree. F., extruding into a chilled die-injection mold, and expressing said molded toy into ice water.
The use as a chewable animal toy of a molded bone, comprising only a single ethylene/methacrylic acid copolymer, ionically cross-linked, ionomer resin having the general formula:
- ##STR5## where M.sup.+ is a metal and wherein the hardness is between 65-100 on the "D" scale, and wherein said hardness is such that when chewed by an intended animal, the toy does not puncture, splinter, shatter, or crack, or prevent biting into said resin but instead shaves off and roughens and bristles whereby the animal is satisfied with the gnawing action and the animal's teeth are scoured and cleaned.
