ABSTRACT:
A safety closure of an aerosol can comprises an externally screw threaded sleeve having a slit extending along one side thereof and an inwardly extending flange at its lower end. The flange is engageable below an upper peripheral rim of the aerosol can after the sleeve has been temporarily flexed apart along its slit to enable the flange to pass over the rim. An internally screw threaded safety cap threadedly engages over the threaded sleeve and prevents the sleeve from flexing apart along the slit so locking the flange under the rim. The safety cap can only be unscrewed from the sleeve if the cap is additionally pressed firmly downwards. Advantageously the safety cap is of a type used as a childproof closure for medicines.
