A hand holdable spray delivery system for dispensing a fluid is provided. This spray delivery system includes a container adapted to house the fluid. The fluid being relatively viscous and preferably also being solids laden. 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 fluid communication so that the fluid 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 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. The internal recess being attached in fluid communication to the distal end of the discharge passage such that the fluid passing through the discharge passage flows through the spray nozzle and converges toward the elongated orifice. The fluid being dispensed therefrom in a fan spray pattern. Several versions of the spray delivery system are illustrated, including a trigger operated sprayer and a reciprocating finger pump. |
