Abstract
A garden roller capable of storing and dispensing a large volume of liquid without immobilizing the roller, includes a hollow drum, preferably made of plastic and having a handle pivotally connected thereto for rolling the drum. A flexible conduit passes outwardly from the interior of the drum through a flow aperture in an end wall of the drum and a seal is provided to prevent escape of liquid through the aperture. Liquid can be dispensed through the conduit via a pump connected to the conduit outside the drum or by pressurizing the interior of the drum. The flexible conduit is weighted at its open end such that it remains adjacent the bottom of the drum enabling the entire contents therein to be dispensed.
