Abstract
Abstract A figure toy or doll having a layered plastic skin including a molded soft, pliable outer skin exteriorly of a substantially rigid, molded inner skeletal shell, and a method for making the same. The figure toy includes a molded smooth, pliable outer skin covering defining the exterior surface and shape of the doll, which is bonded to a substantially rigid molded inner wall interiorly thereof, which provides support for the doll. The method includes the steps of coating the interior walls of a suitable mold cavity with a generally soft plastisol and gelling the plastisol by heating the mold cavity during rotation thereof to form a soft outer covering or skin; coating the interior of the skin with a second plastisol which will cure to form a rigid plastic skeleton to give support to said outer shell; pressurizing the mold cavity; and heat curing both the first and second plastisol during rotation of the mold cavity, then recovering the doll from the mold.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
60 words
A multiple layered figure toy, comprising: a pliable impervious outer smooth molded plastic skin of predetermined shape defining the exterior features of the figure toy; and a substantially rigid impervious inner molded plastic layer of similar material, interiorly cured with said outer skin retaining said outer skin in its predetermined shape and defining an internal cavity within the figure toy.
Claim 2
Dependent Claim
60 words
A multiple layered figure toy, comprising: a pliable impervious outer smooth molded plastic skin of predetermined shape defining the exterior features of the figure toy; and a substantially rigid impervious inner molded plastic layer of similar material, interiorly cured with said outer skin retaining said outer skin in its predetermined shape and defining an internal cavity within the figure toy.
Claim 3
Dependent Claim
26 words
The figure toy of claim 1 wherein said outer skin and said inner wall are heat and pressure cured together simultaneously to prevent relative movement therebetween.
Claim 4
Dependent Claim
31 words
The figure toy of claim 1 wherein the outer skin and the inner wall are substantially homogeneous solids, free of entrapped voids, and differing only in their respective resistance to deformation.
Claim 5
Dependent Claim
37 words
The figure toy of claim 1 wherein the figure toy comprises a head portion having lips, a nose and ears substantially filled by said outer pliable skin with an increased thickness in an attempt to approximate reality.
Claim 6
Independent Claim
174 words
A method of making a multiple layered figure toy, comprising the steps of: providing a suitable mold cavity having a predetermined size and shape for said figure toy; introducing an amount of first plastisol composition into said cavity of a durometer to provide a soft impervious outer skin; partially heat curing said first plastisol as a layer on the interior walls of said mold cavity by heating and rotating the mold cavity; introducing an amount of second plastisol composition into said mold cavity on the interior of said first plastisol layer, said second plastisol composition having a durometer substantially higher than said first plastisol composition to provide a rigidifying backing layer for said first plastisol layer; pressurizing said mold cavity to a predetermined pressure; and heat curing the second plastisol on the interior side of said first plastisol layer while simultaneously completing the curing of said first layer during rotation of the mold cavity to produce a figure toy having a pliable outer skin portion reinforced by a substantially rigid inner wall portion therebehind.
Claim 7
Independent Claim
174 words
A method of making a multiple layered figure toy, comprising the steps of: providing a suitable mold cavity having a predetermined size and shape for said figure toy; introducing an amount of first plastisol composition into said cavity of a durometer to provide a soft impervious outer skin; partially heat curing said first plastisol as a layer on the interior walls of said mold cavity by heating and rotating the mold cavity; introducing an amount of second plastisol composition into said mold cavity on the interior of said first plastisol layer, said second plastisol composition having a durometer substantially higher than said first plastisol composition to provide a rigidifying backing layer for said first plastisol layer; pressurizing said mold cavity to a predetermined pressure; and heat curing the second plastisol on the interior side of said first plastisol layer while simultaneously completing the curing of said first layer during rotation of the mold cavity to produce a figure toy having a pliable outer skin portion reinforced by a substantially rigid inner wall portion therebehind.
Claim 8
Independent Claim
195 words
A method of making a doll having a substantially life-like skin, comprising the steps of: providing a mold having a suitable mold cavity having the desired shape of a doll to be formed; introducing a predetermined amount of a first plastisol composition into said mold cavity, the first plastisol composition having a relatively low durometer when cured; coating the inner walls of said mold cavity with said first plastisol composition; heating said mold when said first plastisol is coated thereon to partially cure said plastisol; introducing a predetermined amount of a second plastisol composition into said mold cavity, the second plastisol composition having a substantially higher durometer when cured; coating the inner walls of said first cured plastisol with said second plastisol composition; introducing a predetermined amount of pressure into said mold cavity to increase the heat conductivity between the mold, the first plastisol, and the second plastisol; and heating said mold a second time to simultaneously complete curing of said first plastisol and cure and bond the second plastisol to the interior of said first plastisol to provide a figure toy having a soft, pliable outer skin bonded to a substantially rigid inner skeleton.
Claim 9
Independent Claim
195 words
A method of making a doll having a substantially life-like skin, comprising the steps of: providing a mold having a suitable mold cavity having the desired shape of a doll to be formed; introducing a predetermined amount of a first plastisol composition into said mold cavity, the first plastisol composition having a relatively low durometer when cured; coating the inner walls of said mold cavity with said first plastisol composition; heating said mold when said first plastisol is coated thereon to partially cure said plastisol; introducing a predetermined amount of a second plastisol composition into said mold cavity, the second plastisol composition having a substantially higher durometer when cured; coating the inner walls of said first cured plastisol with said second plastisol composition; introducing a predetermined amount of pressure into said mold cavity to increase the heat conductivity between the mold, the first plastisol, and the second plastisol; and heating said mold a second time to simultaneously complete curing of said first plastisol and cure and bond the second plastisol to the interior of said first plastisol to provide a figure toy having a soft, pliable outer skin bonded to a substantially rigid inner skeleton.
Claim 10
Dependent Claim
23 words
The method of claim 6 wherein the mold cavities defining the extremities of said figure toy are substantially filled by said first plastisol.
Claim 11
Dependent Claim
14 words
The method of claim 6 wherein said mold is rotated during said heating steps.
