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.

Abstract: A hand holdable spray delivery system for dispensing a relatively viscous and/or solids laden liquid is provided. This spray delivery system includes a container adapted to house the liquid. A manually actuated pump device is mounted on the container. The pump device including an inlet passage, a pump chamber, and a discharge passage having a distal end connected in liquid communication so that the liquid is pumped from within the container, through the inlet passage, into the pump chamber and through the discharge passage upon manual actuation of the pump device. A slotted spray nozzle including a housing having an inlet side and an exit side is also included. The housing having an internal recess through the inlet side that terminates in an elongated orifice at the exit side.
