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.
Claims11
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.

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.
4 more elements
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.
