Abstract

A liquid dispenser for dispensing a liquid from the rim of a toilet bowl such that a controlled, consistent amount of liquid is dispensed into each flush is disclosed. The liquid dispenser includes a bottle for holding the liquid, a base for holding the bottle and for providing a liquid feed conduit between the bottle and a dispensing plate, and a hook for suspending the base from the rim of the toilet bowl. The dispensing plate is integral with or attached to the base, and serves to distribute liquid from the feed conduit to a dispensing position on the upper surface of the dispensing plate where the liquid is contacted by flushing water from the toilet bowl. The dispensing plate has various configurations that assist in the distribution of the liquid to the dispensing position on the upper surface of the dispensing plate. In a preferred version of the liquid dispenser, the dispensing plate has capillary channels in its upper surface for distributing the liquid from the feed conduit to the dispensing position.
