Abstract
Abstract Bodies for use in connection with urinal drains and the like, which are positioned in relation thereto in a manner whereby drain or flush water will come into direct contact with at least a portion of the bodies. The bodies preferably include a solid cleaning and/or sanitizing material which will dissolve in part with each flow of drain or flush water thereby to provide automatic and metered cleaning, disinfecting, deodorizing, and the like, of the urinal. The solid-cleaning and -sanitizing material most useful for urinals is most advantageously in bar or premolded form and comprises, as its essential active ingredients, an intimate admixture of (a) one or more synthetic detergents which are solid at room temperatures, and (b) an acidic agent in the form of one or more acids or acid-forming salts or both, the ratio of the synthetic detergent to the acidic agent in the solid, sanitizing material ranging preferably from about 1 to 100 of the former to about 1 of the latter. The bodies include a holder, which can be placed in a urinal drain or the like, designed to be made economically and to support the cleaning and sanitizing material in a position where drain or flush water will come into direct and extensive contact therewith.
