Abstract

Abstract A dispensing device is provided, connected to a container which holds a liquid to be dispensed, such connection being tight, for purposes of shipping, but being releasable, for movement between two end-closing positions for dispensing liquid from the container. The device is particularly adapted for toilet tank use, with a dispensing device including a buoyant member which functions with the increase and decrease of water level in the toilet tank, in order to dispense a liquid germicide, perfume or the like into the tank. The dispensing device is molded as a onepiece unit, and it is separable into two distinct components.
