ABSTRACT:
A squeeze toy of air-filled elastomer material including a whistle, and a method and apparatus for forming the same. A small cavity or depression is molded into the body of the toy to form the whistle site. A small cap, which may comprise a flat or slightly rounded disk, or a small hollow cylinder, closes the small cavity or depression forming the whistle site. A pair of small openings are formed in centered, aligned relation in the cap and in the bottom of the cavity, completing the whistle. The body of the toy is preferably formed by blow molding techniques, using the opening in the bottom of the cavity corresponding to the whistle hole to blow air in during the molding process, and to blow the finished part out of the mold. The whistle cap is made by separate injection molding techniques.
