Patent ID: 7040554

Claim:
An apparatus for spreading a flowable product ( 2 ), said apparatus comprising: a product container ( 4 ) for containing the flowable product ( 2 ); and a spray head ( 1 ) for receiving the flowable product ( 2 ) from the product container ( 4 ) through a product feeder ( 5 ), said spray head ( 1 ) discharging and spreading the flowable product ( 2 ), said spray head ( 1 ) having an upper coupling member ( 7 ) connected to a feed conduit ( 3 ), a lower coupling member ( 8 ), and a nozzle member ( 9 ) disposed between said upper coupling member ( 7 ) and said lower coupling member ( 8 ), said upper coupling member ( 7 ) and said lower coupling member ( 8 ) being tightly attached and interconnected to each other when spreading the flowable product ( 2 ), said upper coupling member ( 7 ) and said nozzle member ( 9 ) together defining a space ( 13 ) for distributing the flowable product ( 2 ) being fed through the feed conduit ( 3 ) into said spray head ( 1 ) to said nozzle member ( 9 ), said nozzle member ( 9 ) having spraying nozzles ( 18 ) for discharging the product ( 2 ) when said spraying nozzles ( 18 ) are subjected to pressure by the product ( 2 ), said spraying nozzles ( 18 ) being closed when said spraying nozzles ( 18 ) are not subject to pressure by the flowable product ( 2 ), said upper and lower coupling members ( 7 , 8 ) being disconnectable from each other, said nozzle member ( 9 ) being removable from said upper and lower coupling members ( 7 , 8 ) when said upper and lower coupling members ( 7 , 8 ) have been disconnected from each other, said upper coupling member ( 7 ) including an upper wall ( 10 ) having an inlet ( 11 ) for the product ( 2 ), said upper wall ( 10 ) having a downwardly directed collar ( 12 ) defining an outer wall of said space ( 13 ), said collar ( 12 ) engaging a disc member ( 21 ) of the nozzle member ( 9 ), said nozzle member ( 9 ) having distributing walls ( 31 ) extending in a radial direction outwards from an axially directed, geometric centre line (CL), said axially directed, geometric centre line (CL) extending through said spray head ( 1 ), said distributing walls ( 31 ) defining said space ( 13 ).
