Abstract
Abstract A doll supports a quantity of rooted hair fabricated to provide a posable or cold setting characteristic. The posable hair is formed of an amorphous thermoplastic material preferably having a high molecular weight in a compound including plasticizers, heat stabilizers and lubricants. The material is formed to provide a combination of glass transition temperature characteristic and hardness to produce the cold setting or posable quality.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
96 words
A posable hair doll comprising: a doll head having a hair-supporting portion thereon; and a plurality of posable synthetic hair filaments each formed of a posable nonmetallic material being cold formable into a desired shape or set and tending to retain said desired shape or set when released and being restorable to their previous shape by heatless brushing or combing, said synthetic hair filaments being formed of an amorphous thermoplastic material having a glass transition temperature between zero degrees centigrade and plus twenty degrees centigrade and a hardness between eighty and one hundred Shore A Durometer.
Claim 2
Dependent Claim
96 words
A posable hair doll comprising: a doll head having a hair-supporting portion thereon; and a plurality of posable synthetic hair filaments each formed of a posable nonmetallic material being cold formable into a desired shape or set and tending to retain said desired shape or set when released and being restorable to their previous shape by heatless brushing or combing, said synthetic hair filaments being formed of an amorphous thermoplastic material having a glass transition temperature between zero degrees centigrade and plus twenty degrees centigrade and a hardness between eighty and one hundred Shore A Durometer.
Claim 3
Dependent Claim
20 words
A posable hair doll as set forth in claim 1 wherein said amorphous thermoplastic defines a high molecular weight characteristic.
Claim 4
Dependent Claim
26 words
A posable hair doll as set forth in claim 2 further including a plurality of non-posable synthetic hair filaments interspersed throughout said posable synthetic hair filaments.
Claim 5
Dependent Claim
30 words
A posable hair doll as set forth in claim 3 wherein said posable synthetic hair filaments and said nonposable synthetic hair filaments are generally equally distributed upon said doll head.
Claim 6
Dependent Claim
28 words
A posable hair doll as set forth in claim 3 wherein at least some of said posable synthetic hair filaments are grouped to form a posable pony tail.
Claim 7
Dependent Claim
84 words
For use in combination with a doll, a plurality of hair filaments formed of a material comprising a compound of not less than 60% nor more than 75% by weight of a high molecular weight polymer or copolymer of polyvinyl chloride; and not less than 20% nor more than 35% by weight of a plasticizer; and not less than 3% nor more than 10% by weight of a heat stabilizer; and not less than 0.5% nor more than 1.5% by weight of a lubricant.
Claim 8
Dependent Claim
84 words
For use in combination with a doll, a plurality of hair filaments formed of a material comprising a compound of not less than 60% nor more than 75% by weight of a high molecular weight polymer or copolymer of polyvinyl chloride; and not less than 20% nor more than 35% by weight of a plasticizer; and not less than 3% nor more than 10% by weight of a heat stabilizer; and not less than 0.5% nor more than 1.5% by weight of a lubricant.
