Abstract

The pressure activated cleaner discharge device is used in a standard toilet water tank, the tank having a ballcock for discharging water to fill the tank from a minimum water level to a maximum water level. The tank also includes a flush valve connected to a toilet bowl for flushing water therein from the tank, and an overflow pipe projecting above the maximum water level having a ballcock refill tube connected thereto for directing a pressure flow of tank water to refill the toilet bowl after said flushing. The cleaner discharge device includes a container in the tank having an inlet and outlet, an inlet water tube connected between the refill tube and the container inlet, and an outlet cleaner tube connected between the container outlet and the refill tube downstream of the inlet water tube connection. The refill tube and its connections and the container and its connections are all liquid-tight from the ballcock to the refill pipe substantially throughout the downstream flow of water therein. Furthermore, the connection between the outlet cleaner tube and the refill tube may have means for increasing the drawing of the liquid cleaner from the container and these additional devices may be a venturi, a right angle projecting tube with either downstream holes or a downstream angled end, or an angled tube angling downstream, any one or all.
