Abstract: A security seal for an aerosol container (12), which has an actuator (16) in communication with a valve (14). Means are provided such as adhesive (24), contact cement or a weld to deter removal of the actuator (16) from the valve system (14). The valve system (14) and actuator (16) are made of compatible materials so they may be joined by laser or sonic welding, or by solvent cement. Optionally, a collar (26) has a first ledge (28) that locks under rim (18) and has a second ledge (30) that engages a base portion (27) of the actuator and prevents its removal, except by breaking the collar. The security seal can include means such as a cap (34) which is joined to the collar (26) by a frangible connection (38), to provide a tamper indication of whether the actuator (16) has been accessed.
