ABSTRACT:
A double-walled container having a bottom wall, an exterior wall, and an interior wall disposed in concentric relation to the exterior wall. The bottom wall, the exterior wall, and the interior wall define a liquid fluid-holding reservoir. An annular top wall interconnects the exterior wall and the interior wall at their respective uppermost rims. A fill opening formed in the top wall enables introduction of liquid fluid into the liquid fluid-holding reservoir. The interior wall and the bottom wall define a soil or liquid fluid-holding space. A flow control valve extends through a first opening formed in the exterior wall and a second opening formed in the interior wall. Liquid fluid in the liquid fluid-holding reservoir is introduced into fluid communication with soil in the soil-holding space by opening the flow control valve. In another embodiment, a flask is retrofit into a single-walled container.
