Dispenser for delivering portions of pasty substances has an emptying nozzle (18) associated with a squeeze head (13), and a tubular housing (1) in which a plunger (9) is displaced in a stepwise manner during a process of emptying the dispenser. Displacement of the plunger occurs in the direction toward the nozzle (18). The squeeze head can be pressed in, in the direction of the plunger (9), and can be actuated via a handle (H). A cover (21) closes an opening (20) of the nozzle (18). A pivot-pin connection (DV) is provided between the cover and the nozzle, and a slit/pivot pin mounting (23/22) is disposed between cover and the housing such that, once the cover has been displaced open partially, the pivot pin (22) is displaced in the pressing-in direction of the squeeze head (13), and the nozzle is carried along in the process, by way of support against a housing-side abutment (w).
