An attachment for an aerosol dispensing package includes an actuator having at least one cam and a mounting cap having an upstanding wall and at least one inner rim to engage the cam. The actuator includes a spray nozzle and a downwardly extending projection, in fluid communication with the spray nozzle, to sealingly engage an upwardly projecting stem of an aerosol valve when the actuator is in a dispensing position. The cam engages the inner rim to lower the actuator to the dispensing position and raise the actuator to the non-dispensing position. The upstanding wall at least partially surrounds the actuator, and includes a lateral opening adjacent to the spray nozzle when the actuator is in the non-dispensing position, and a spray opening adjacent to the spray nozzle when the actuator is in the dispensing position. A nozzle closure, having a projection fitting into the lateral opening and the spray nozzle, may be hingedly attached to the mounting cap. The nozzle closure projection may seal the spray nozzle when the actuator is in the non-dispensing position. Safety and tamper evident tabs may also be included.
