The invention relates to a dispenser (1) for liquid and/or pasty masses, comprising a pump chamber (9) with an inlet (10) and an outlet valve (11) and a dispenser head (12), wherein the dispenser head (12) is provided with an essentially cup-shaped lower piece (8), forming a separating wall to a reservoir (2) with a return spring (5) arranged between the lower piece (8) and the dispenser head (12) which is supported at one end on the dispenser head (12) and on the lower piece (8) at the other end. According to the invention, a conventional dispenser may be improved by provision of a recessed groove (26) running in the lower piece (8) through the separating wall, radially external to the seat of the return spring (5) on the lower piece (8) in which a cover for the dispenser head (12) may be housed on operation.
