  • Pacifier
    Patent number: 4193407
    Abstract: A baby pacifier of the type that includes a hollow resilient nipple and a ring-shaped handle that extend outwardly in opposite directions from a substantially rigid disc that has a diameter of sufficient magnitude to prevent the disc entering the child'mouth. The nipple contains a non-toxic material, for example table salt, that has a disagreeable taste and a non-toxic dye. Upon a baby biting through the nipple, the non-toxic material subjects him to a disagreeable taste, and the baby rejects the pacifier.
