The dispenser has a push button for controlling an aerosol valve or pump, or a stopper for a receptacle having flexible, compressible walls. The dispenser is characterized in that it comprises a nozzle (3) with an elastically deformable distribution slot (7) which nozzle is integrated by molding into a relatively rigid body (1).
