ABSTRACT:
A safety sprayer is set forth for use in combination with the spray dispensing of fluid within associated containers. A spray head is selectively locked in a first position and unlocked upon a 90 degree rotation of the spray head relative to an associated closure top. The spray head is vertically reciprocatable relative to an axially concentric and surrounding enclosure tube wherein the closure tube is permanently threaded to the top closure whereupon the enclosure tube must be rotated 90 degrees also relative to a cap threadedly engaging an associated storage container wherein the cap is provided with a plurality of diametrically opposed recesses accepting diagonally opposed flanges integrally associated and orthogonally disposed relative to the enclosure tube that are to be rotated out of the recesses to enable the enclosure tube to sealingly engage a plug seal associated with the mouth of the bottle to enable fluid to be directed from the bottle through the spray head during use.
