Abstract
Abstract A doll simulating a warm-blooded human baby or other mammal form is provided with an internal vessel containing an exothermic salt and means to introduce water into the vessel to activate the salt to release heat. The heat is transferred to the wall of the doll to provide a feeling of body warmth.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
80 words
A doll simulating a warm-blooded mammal comprising a head, torso and limb portions, a non-porous heat conductive skin covering said portions, a quantity of an exothermic salt contained within at least one of said portions, said quantity of said salt being sufficient, when wet, to produce heat to warm said skin to a temperature simulating that of a warm-blooded mammal, and fluid communication means extending from the outside of said skin to said salt for wetting and drying said salt.
Claim 2
Dependent Claim
80 words
A doll simulating a warm-blooded mammal comprising a head, torso and limb portions, a non-porous heat conductive skin covering said portions, a quantity of an exothermic salt contained within at least one of said portions, said quantity of said salt being sufficient, when wet, to produce heat to warm said skin to a temperature simulating that of a warm-blooded mammal, and fluid communication means extending from the outside of said skin to said salt for wetting and drying said salt.
Claim 3
Dependent Claim
12 words
The doll of claim 1 wherein said doll simulates a human baby.
Claim 4
Dependent Claim
18 words
The doll of claim 1 including an effectively closed vessel in said one portion containing said exothermic salt.
Claim 5
Dependent Claim
30 words
The doll of claim 3 including an orifice extending through said skin and connected with said fluid communication means for forming a fluid communication between said vessel and said orifice.
Claim 6
Dependent Claim
30 words
The doll of claim 4 including a one-way valve interposed between said orifice and said vessel and oriented for restricting fluid flow in one direction between said vessel and orifice.
Claim 7
Dependent Claim
33 words
The doll of claim 5 wherein said fluid communication means includes a conduit member extending into said vessel from said orifice to enable the flow of fluid from said orifice into said vessel.
Claim 8
Dependent Claim
35 words
The doll of claim 4 wherein said fluid communication means includes at least an escape opening in said vessel communicating with an orifice in said skin to enable the escape of fluid from said vessel.
Claim 9
Dependent Claim
13 words
The doll of claim 7 wherein said vessel extends into said limb portions.
Claim 10
Independent Claim
122 words
An apparatus for simulating a warm-blooded mammal comprising a body portion in the configuration of a mammal, including torso, limb and head portions, a non-porous plastic heat conductive skin enclosing said apparatus, a fluid-tight container in said body portion having a fluid input orifice, conduit means extending from an inlet opening in said skin extending from outside of said body to said input orifice, a quantity of exothermic salt within said container sufficient to warm said skin when activated by water supplied thereto from said opening, heat transfer filler material occupying the space between said skin and said container, and a fluid outlet opening in said skin communicating with said container and said exothermic salt to permit the exhaust of fluid therefrom.
Claim 11
Independent Claim
122 words
An apparatus for simulating a warm-blooded mammal comprising a body portion in the configuration of a mammal, including torso, limb and head portions, a non-porous plastic heat conductive skin enclosing said apparatus, a fluid-tight container in said body portion having a fluid input orifice, conduit means extending from an inlet opening in said skin extending from outside of said body to said input orifice, a quantity of exothermic salt within said container sufficient to warm said skin when activated by water supplied thereto from said opening, heat transfer filler material occupying the space between said skin and said container, and a fluid outlet opening in said skin communicating with said container and said exothermic salt to permit the exhaust of fluid therefrom.
Claim 12
Dependent Claim
47 words
In combination with the apparatus of claim 9, a bottle having a nipple adapted to fit said inlet opening in an air-tight relationship, said bottle having a volume sufficient to supply a quantity of water to said salt to activate said exothermic salt to heat said body.
Claim 13
Dependent Claim
78 words
A heatable doll comprising a non-porous skin, a container in said doll, a quantity of exothermic salt in said container for activation by a fluid to exude heat that is felt at the skin, opening means on said skin, and fluid communication means between said opening means to communicate activating fluid to said salt from outside said skin and to permit the evaporation of said activating fluid from said salt to enable said salt to dry for reuse.
Claim 14
Dependent Claim
78 words
A heatable doll comprising a non-porous skin, a container in said doll, a quantity of exothermic salt in said container for activation by a fluid to exude heat that is felt at the skin, opening means on said skin, and fluid communication means between said opening means to communicate activating fluid to said salt from outside said skin and to permit the evaporation of said activating fluid from said salt to enable said salt to dry for reuse.
