1. A spray dispenser for dispensing and atomizing liquid comprising:
- a. a reservoir for storing a viscous liquid;
b. means to deliver viscous liquid under pressure from said reservoir to a delivery passageway;
c. a nozzle having two outlets which provide intersecting streams of viscous liquid during dispensing;
said nozzle including;
i. a post having an inlet end and an outlet end in fluid communication with the viscous liquid in said delivery passageway;
said post mounted in said delivery passageway to form a fluid flowpath between said post and said delivery passageway;
ii. a first groove and a second groove located on said post;
iii. said first and second grooves having a preselected length and extending to said outlet end of said post;
iv. a groove containment cap mounted in said delivery passageway, said cap located at a preselected point along said first and second groove to provide top confinement to said grooves at a preselected point intermediate to the outlet end of said post so that said grooves have top confinement for at least a portion of their length;
said groove containment cap terminating prior to termination of said grooves at the outlet end of said post whereby said grooves extend along said post from said groove containment cap to the post outlet end without top confinement;
v. said grooves having a preselected greater depth at the outlet end of said post than at the inlet end of said post so that fluid flowing along said first groove intersects with fluid flowing along said second groove at a preselected impingement angle after said fluid is discharged from the dispenser;
vi. said grooves providing a flow path for viscous liquids during dispensing;
vii. means to direct fluid flowing along said flow path through said outlets during dispensing;
viii. said groove containment cap having a central outlet for snug receipt and engagement of said post;
ix. said central outlet having side walls;
x. said side walls engaging said post and providing said top confinement of said grooves prior to dispensing said viscous liquid.

Abstract
A spray dispenser for dispensing and atomizing viscous liquids and a system for dispensing same is provided. The dispenser includes a reservoir for storing a viscous liquid. The viscous liquid is delivered under pressure from the reservoir to a delivery passage. A nozzle is provided with two opposed outlets to the atmosphere which provides intersecting streams of viscous liquid during dispensing.
