1. Discharger.
2.1. The invention relates to a discharger for a flowable medium, comprising a discharge opening (112) on the one hand, and a medium container or a fastening device (114) for a medium container on the other hand, which are disposed at opposite ends of the discharger in mutual alignment along a principal direction of extent (102) of the discharger, and a pumping device (120) having a pumping chamber closed off on one side by a piston (124), the piston (124) being configured such that it is longitudinally movable along a pumping direction for the generation of a discharge pressure and the pumping direction forming approximately a right angle with the principal direction of extent (102).
2.2 According to the invention, the piston (124) is operatively connected to an actuating device (130) which can be manually pressed in in the pumping direction and which, in a delivery state of the discharger, is held by a securing element (150) in a pressed-in state in which the pumping chamber has a small volume. 2.3 The discharger according to the invention allows, in particular, an advantageous handling in connection with the assembly.
