Patent attributes
An irrigation system having a reservoir with self-sealing openings is provided. The reservoir comprises a body having an outer surface and a cavity for storing fluid. The reservoir also includes a plurality of self-sealing openings on the outer surface and configured to move between a first configuration in which the self-sealing openings are closed and a second configuration in which the self-sealing openings are open and permit fluid to release from the cavity to a target zone. The self-sealing openings are in the first configuration when a fluid pressure in the reservoir is at least one of zero pressure or negative pressure and the self-sealing openings are in the second configuration when the fluid pressure in the reservoir is a positive pressure relative to an external pressure.
