Abstract

For the discharge, particularly atomization of media, particularly liquid medicaments, a dispenser (11) is provided, which discharges a charge of the medicament in only one or optionally a few strokes. Actuation takes place between three fingers of the user, the thumb pressing an actuating pusher (80) in the actuating and discharge direction. In order to prevent an unintentional actuation and simultaneously protect the discharge opening (44) against dirtying and contamination, a protective cap (90) is provided, which covers the entire discharge section (13) and the holding surfaces (14) for actuation. It also has web-like projections (93) extending up to the actuating pusher (80) and securing the latter, which prevents an actuation when the protective cap is fitted. However, actuation is possible after removing the protective cap, which is secured by a snap connection.
