Abstract
A toilet bowl cleaning means wherein a container is located within a water tank associated with the bowl with a cleaning compound such as calcium hypochlorite included within the container. A plurality of openings are provided, and this provides exposure to water in the tank so that the compound will be dissolved in the water and thereby delivered to the bowl when the toilet is flushed. The openings may be formed in a centrally located cylinder with the compound located within the cylinder and with a water space between the cylinder and the outer container walls. Controlled amounts of compound are thereby released to the water in this area.
