  • Patent number: 5005224
    Abstract: The Toilet Bowl Silencer Dish is an accessory for the common household bathroom toilet bowl. It allows the adult male the capability to stand and use the toilet bowl without splashing urine or generating audible noise. A glazed ceramic dish is attached to a counterbalance and draped over the rim of the toilet bowl. Monofiliment line is looped through specially designed rings molded on the back side of the dish. This monofiliment twine is then looped through the counterbalance. The attached assembly will fit any toilet bowl shape. The dish hangs in a vertical position offering a concave target to the user. By directing his column of liquid, the user is able to avoid direct disruption of the noise generating toilet bowl water surface. The concaved shape of the dish blends with the rotating current of the swirling flush water and does not interfere with or obstruct the flushing action of the toilet.
