  • Patent number: 5080110
    Abstract: The invention is an external ring, a radial collar, and a protruding portion which extends inside the ear canal to dampen sound. In the preferred embodiment, the collar and the exterior of the protruding portion are molded of a soft, flexible rubber, and the ring is made of a rigid plastic and includes an extending cylindrical core which inserts into the protrusion to make the two parts integral. The ear plug has a dual function, first, to conveniently permit insertion of the plug into the ear to the proper depth automatically and to prevent its easy removal, and secondly, to imitate as exactly as possible a scaled down version of a baby pacifier to enhance the ability to sell a pair of the units as novelty items.
