Floor drain odor control device

DETAILED DESCRIPTION The floor drain odor control device of the present invention removably inserts into standard floor drains of various sizes and contains a washable and regenerable carbon-based adsorbent, and preferably a catalytically-active carbonaceous char such as Centaurs, described in U.
S.
Pat.
Nos.
5,356,849 and 5,444,031, which reduce odors associated with and originating from floor drains through adsorption and, preferably, through catalytic reaction as well.
In addition, contrary to prior art, the carbon-based adsorbent in the device regenerates when washed or contacted with water or aqueous solutions, and, therefore, the device is designed to facilitate such washing of the adsorbent.
In a preferred embodiment, the device includes a container for holding the adsorbent, which container is screened and/or has openings throughout to allow both water (and aqueous solutions) and gases to pass through the container and contact the adsorbent, and a flange which extends from the outer perimeter of the the container, rests on the top of the floor drain and fits underneath and is secured by the floor drain cover.
