  • Doll having simulated hair-cutting feature
    Patent number: 6139397
    Abstract: A doll head supports a pair of retracting mechanisms which provide a rotating spool upon which a quantity of hair forming a hair bundle is wound. The retracting mechanisms are operated in response to the child user squeezing the extending portion of the mechanisms at the base of the hair bundles in a simulated hair-cutting action. Each squeeze of the simulated scissors triggers an incremental spring-driven retraction of the hair bundle thereby shortening the hair bundle and simulating hair-cutting. A releasable latch mechanism operative within the retracting mechanisms allows the hair bundles to be drawn outwardly to their maximum length to repeat the hair-cutting cycle.

  • Toy nursing bottle for a doll
    Patent number: 5176561
    Abstract: A toy nursing bottle for simulating emptying of the bottle when the doll is "drinking" and "filling" the bottle from a can or the like. The bottle body is formed of outer and inner shells defining a liquid receiving chamber therebetween, a nipple member mounted on the bottle body and having a liquid receiving reservoir, and a valve that controls flow of liquid between the liquid receiving chamber and the liquid receiving reservoir. A rod extends from the valve member through the reservoir and into the nipple, so that it moves, when the nipple is depressed, to open the valve. Any surface on a container, such as a can, bottle or cardboard container or the like, may be used to depress the nipple to open the valve.

  • Simulated feeding apparatus
    Patent number: 5118321
    Abstract: A utensil which has a feeding end and a hollow handle. A holding element is displaceable within the hollow element relative to the feeding end between a revealing position, where an end of the holding element that is decorated with imitation food projects over the feeding end, and a hidden position, where the decorated end of the holding element is withdrawn and concealed within the hollow handle. A spring biases the holding element into the hidden position and a latch retains the holding element in the revealing position. The holding element enters the revealing position during withdrawal of the utensil from a toy container and enters the hidden position during insertion of the feeding end into a doll`s mouth.
