Abstract
A chew toy for animals is molded into the shape of a familiar animal food item, such as a dog bone, from a polymer composition which is both edible and degradable. The composition is essentially comprised of a starch material and a degradable ethylene copolymer, preferably poly-ethylene-acrylic acid or poly-ethylene, vinylalcohol. The preferred weight ratio of the ethylene copolymer and the starch material is within the range of about 1:1 to 2:1. Plasticizers and edible lubricants can also be added to the composition.
Claims5
An edible chew toy for animals molded into a desired configuration from a degradable polymer composition comprising:
- a first material selected from the group consisting of starch, starch hydrozolate and starch destrines and mixtures thereof;
- and a degradable ethylene copolymer selected from the group consisting of poly-ethylene-acrylic acid, poly-ethylene-vinylalcohol and mixtures thereof;
- and wherein the weight ratio of said ethylene copolymer and said first material is within the range of about 1:6 to 2:1.
An edible chew toy for animals molded into a desired animal food configuration from a degradable polymer composition comprising:
- a first material selected from the group consisting of starch, starch hydrozolate and starch destrines and mixtures thereof;
- and a degradable ethylene copolymer selected from the group consisting of poly-ethylene-acrylic acid, poly-ethylene vinylalcohol and mixtures thereof;
- and wherein the weight ratio of said ethylene copolymer and said first material is within the range of about 1.6 to 1.1.
An edible chew toy for animals molded from a degradable polymer composition so as to define a dog bone, said composition being comprised of a starcheous material having a degradable ethylene copolymer disbursed therein and wherein the weight ratio of said ethylene copolymer and said starcheous materials is within the range of about 1.6 to 1.1.
An edible chew toy for animals formed of a thermo-plastic blend comprising:
- a first material selected from the group consisting of starch, starch hydrolyzate, starch destrines and mixtures thereof;
- a degradable ethylene copolymer;
- and an edible lubricant selected from mono-, di-, and tri-esters of edible polyhydric alcohols with edible higher fatty acids and phospholipids.
