Patent ID: 7472840

Claim:
An arrangement of at least two sets of nozzle inserts for use in irrigation systems comprising: a first carrier; a first set of irrigation nozzle inserts releasably connected to the first carrier, each insert having a body portion adapted for reception in a cooperating nozzle cavity and each insert defining a port configured for distribution of water in a predetermined irrigation spray pattern; a second carrier; a second set of irrigation nozzle inserts releasably connected to the second carrier, each insert having a body portion adapted for reception in a cooperating nozzle cavity and each insert defining a port configured for distribution of water in a predetermined irrigation spray pattern; a coupler capable of releasably interconnecting the second carrier with the first carrier; wherein the irrigation nozzle inserts of the first and second sets being at least partially nested among each other when the first carrier is interconnected with the second carrier to resist unintentional detachment of the nozzle inserts from their respective carrier; wherein the irrigation nozzle inserts of the respective sets are disposed so that each is interposed between two irrigation nozzles inserts of the other set when the first carrier is interconnected with the second carrier; wherein the irrigation nozzle inserts of the first and second sets are disposed in a generally radial-shaped pattern about their respective carrier; wherein the first and second carriers each include a plurality of arms and each irrigation nozzle insert is connected to its respective carrier by at least one of the arms; wherein the coupler comprises one of the first and second carriers having a projection and the other of the first and second carriers defining a recess that receives the projection to releasably interconnect the second carrier with the first carrier.
