Abstract
Abstract The present invention relates to an improved urinal block composition comprised of fluid-soluble chemical components, and an improved dispenser to be used with that urinal block. Specifically, the present invention is directed to a unique combination of chemicals that when blended together to form a urinal block composition yields a stable product that is effective at deodorizing and cleaning urinals and toilets. The improvement of using an acid stable protease enzyme with the other fluid-soluble chemical components of the urinal block composition provides the advantage of dissolving and otherwise neutralizing odors associated with urinals and toilets. The urinal block is retained in and dispensable from a disposable dispenser assembly 10 for use in urinals and toilets. The urinal block is protected from direct action of urine by a retention cup 18 which retains the chemical block composition 32 in position, and the inner hollow area 12 of the dispenser 10 allows the dispenser 10 to fit around strainers found in urinals. The dispenser has a perforated flange 20 that supports the hollow area 12 and retention cup 18 within the urinal, while also allowing for effective drainage.
