Abstract
Abstract A ventilating means for the top of the pan or seat portion of the sanitary system. The ventilating means is provided by complementary top sections which are joined together in such a manner that intermediate portions thereof are spaced apart to provide a hollow member. Malodorous gases pass through ventilating holes in the lower section into the space between the complementary sections. An exhaust communicates with the space of the hollow device for carrying off the malodorous gases.
