  • Female playing doll, capable of imitating pregnancy and child birth
    Patent number: 5308277
    Abstract: In order to enable an imitated child birth from a doll the doll body is shaped with a stomach cavity covered from the inside by a flat stomach piece, which is held in a normal position by a spring. When the doll is desired to be pregnant the stomach piece is pressed inwardly, and a baby doll is laid into the cavity provided thereby, this cavity then being closed from outside by means of a separate, bulging stomach element. When it comes to the `birth` this element can be removed, whereby the baby doll is pressed out by the biased flat stomach piece, which will then automatically return into its normal position.
