3 Claims. (Cl. 222-182)
This invention relates to a cap for a spray dispenser,
or the like, and more particularly, to a cap which is
detachably securable to a dispenser having a cylindrical
body and a valve element extending outwardly thereof
‘for manual actuation to release ?uid or gas under pres
sure contained therein.

to manufacture and capable of mass production.
These and other objects of this invention will be more
