ABSTRACT:
A nozzle for dispensing fluids with suspended solid particulates without experiencing permanent partial or total clogging is provided. The nozzle is made from a elastomeric material and has a dome-shaped tip. The dome-shaped tip has a slit that provides an elongated orifice which generates a fan-type spray pattern while allowing solid particulates to pass through the nozzle without permanent clogging. The slit is normally maintained closed at rest and provides precompression and shut-off functions. Several versions of the nozzle are described, such as a one-piece nozzle and a nozzle insert. Additionally, the nozzle can be attached to a manually actuated pump device and be used as a spray delivery system.
