ABSTRACT:
A method of construction and resulting unitary latex pacifier is disclosed. The pacifier is constructed with the nipple section prefabricated as one unit and placed on a central post of a shield mold. Latex is poured around the nipple to form the shield and nipple as a single piece. While the latex is curing, it is removed from the mold, and the handle portion of the pacifier is dipped in liquid latex and inserted in the bottom of the shield to form a unitary construction. The handle section has been previously fashioned in a mold itself. Alternatively, an encircling ring which is used as reinforcement can be placed on the post followed by the nipple with the shield latex poured over that unit. Under pressure, the handle is then forced into the nipple before curing takes place. The resulting pacifier exhibits one-piece construction which will not separate or disintegrate into component parts which may be ingested by an infant. Various shield shapes may be utilized, including a tapered shield or a reinforced edge portion. The shield also has a series of holes in it.
