An overcap and nozzle for an aerosol can or the like. The overcap has a finger depression in its top extending part way across and intersecting a nozzle opening also formed in the cap and through which the top of the nozzle protrudes. A user lays his finger in the recession and presses on the nozzle to release the spray out of a lateral orifice in the nozzle. The cap and nozzle have cooperating means which ensure their relative orientation with the orifice pointed away from the user. The cooperating means consist of a key and a keyway formed in the adjacent surfaces of the nozzle and the nozzle opening in the overcap. A ledge lying in a plane that is inclined to the axis of the nozzle is also formed on the surface having the keyway and engageable by the key so as to produce relative rotation of the nozzle and overcap as they are telescoped together longitudinally by insertion of the nozzle into the nozzle opening, thus ensuring entry of the key into the keyway without the necessity for careful manual or visual inspection by an operator.
