  • 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.

  • 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imitation food projects over the feeding end, and a hidden position, where the decorated end of the holding element is withdrawn and concealed within the hollow handle.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.

  • Patent number: 4551114
    Abstract: An impact-activated toy suitable for use in a child's crib which is capable of generating a series of melodies in response to successive impacts by a child spaced by more than, for example, ten minutes from the termination of the preceding melody. A momentary push-button switch for the mother's use is provided to cause the toy to generate a series of melodies in response to actuation by the mother when no melody is being generated or to stop the generation of any melody being generated at the time of the switch actuation.

  • Patent number: 4363181
    Abstract: A mobile is rotated by an energy storage device to which energy is periodically transferred by a motor which is in turn controlled by an electronic circuit. The electronic circuit simultaneously controls a loudspeaker to produce a wide variety of music with variations in tune, tonal quality, key, tempo, and loudness.

  • Patent number: 4280809
    Abstract: An educational toy for testing a child's ability to properly associate logically related symbols and teaching proper associations. The toy includes an area for displaying two groups of symbols in a predetermined array on a housing and two members movably mounted to the housing so that the child may move each member into alignment with a symbol from one of the groups. In response to manual actuation of a switch, the toy emits a first signal, indicative of a correct performance, if the members are in alignment with logically related symbols at the time of such actuation and emits a second signal, indicative of incorrect performance, if the members are not so aligned at the time of such actuation. In a preferred embodiment, the toy includes electronic detection and signalling circuitry, a programmed microprocessor forms a part of the detection and signalling circuitry, and the microprocessor may be manually controlled to act in other play modes.
