Abstract:
1. A timed release irrigation device comprising: a unitary container having upper and lower chambers partitioned by a central separator plate therebetween, said lower chamber being enclosed and defining a first fluid reservoir adapted to contain a first body of liquid, and said upper chamber defining a second fluid reservoir for containing a second body of fluid; a liquid discharge member projecting from the bottom portion of said lower chamber for enabling selective release of liquid therefrom; said upper chamber having an open top portion to provide fluid communication between the second body of fluid and the ambient environment, said upper chamber second fluid reservoir having a closed bottom portion defined by said separator plate and a mechanism for regulating the evaporation rate of the second body of liquid to the ambient environment; and a trigger mechanism passing through said separator plate between said upper and lower chambers for releasing the liquid from said first fluid reservoir through said discharge member, said trigger mechanism being actuated by said evaporation rate regulating mechanism.
