35. A spray delivery system for aerosol products, comprising:
a shell having a first wall with first and second apertures therein, a second wall and a housing extending outwardly from said shell and surrounding said first aperture;
a lock having a first end with a depressible button and a second end with a spring, said button extending through said second aperture of said shell, said spring being within said housing and movable from a first position wherein said button extends through said second aperture and outwardly from said shell an axial distance less than said housing, to a second position wherein said button is depressed and a substantial portion thereof is contained within said shell and said spring is compressed against said second wall of said shell and exerts a biasing force on said lock to automatically return it to said first position;
an actuator having a top, a nozzle and at least one projection extending downwardly from said top and slideably engaging a portion of said lock, said nozzle being contained and vertically movable within said housing, said projection further contacting said portion of said lock so that it is thereby prohibited from vertical movement when said lock is in said first position and is capable of vertical movement when said lock is in said second position; and
a canister in partial contact with said actuator, said canister including a level indicator on the outer surface thereof.
